This technology is a fire-resistant composite floor panel featuring upper and lower plates facing each other with a rim to create a filling space. Inside, a wire-mesh fire-resistant holding reinforcement is fixed to the plates, and the space is filled with fire-resistant synthetic resin. As the resin penetrates the mesh and hardens around its free ends, the plates and the filler are integrated into a single unit.
Traditional floor construction relies on wet methods involving formwork, concrete pouring, and curing, which require temporary works, long curing times, and complex on-site labor. These processes also incur high costs and CO2 emissions from concrete production and waste disposal. While sandwich panels are common for non-structural partitions, metal-reinforced versions often fail as fire-rated flooring because the internal resin can vaporize, melt, or delaminate from the metal at high temperatures.
This technology connects a first wire mesh to the lower plate and cross-welds a second wire mesh vertically to form a 3D grid. The lower plate surface is textured with aggregates, folded plates, or embossed patterns to enhance adhesion to the resin. Optionally, stud bolt shear connectors with wide heads can be used to meet specific design requirements. Suitable for dry floor slabs in steel buildings, modular home floor panels, and prefabricated structural panels, it slows deflection during fires without concrete pouring, achieving the standard 2-hour fire resistance rating.
This technology is a fall prevention device consisting of a footrest with an insertion part that installs into the outer surface of a utility pole and a support part with a cross-section wider than it is tall, along with a sole component fixed to safety shoes that features multi-angled, overlapping grooves designed to fit the footrest. When a worker steps on the footrest, the grooves in the sole interlock with the footrest to prevent the foot from slipping.
Utility pole workers climb up and down by stepping on rod-shaped metal step bolts while wearing safety shoes, but fatal accidents involving falls from heights of up to 10 meters while changing positions have occurred consistently. Existing technology, which applies anti-slip metal particles to the surface of step bolts, becomes slippery again once the particles or shoe soles wear down, and it has limitations in that it easily slips even with slight movement while standing on the bolt, not just during climbing.
In this technology, the temporary coupling grooves of the sole component are formed to overlap at various stepping angles, ensuring they interlock with the footrest regardless of the angle of approach. Additionally, directional protrusions extending along the insertion part prevent the support from wobbling. The head at the end of the footrest features a through-hole for attaching a worker's safety lanyard, with a diameter set to no more than half the width of the support. Applicable to utility pole climbing steps, street light or tower inspection footrests, and safety shoes for electrical workers, this device reduces slip-related falls when standing or moving without requiring major changes to existing step bolt structures.
This technology is a ladder safety device that secures a leaning ladder to an external structure, such as a utility pole, by attaching a support frame to the ladder rungs under a hollow, rim-style main frame that allows the worker to pass through, and fastening the front locking mechanism to the structure. A folding seat is attached to the rear of the main frame with a hinge, allowing the worker to sit while working on the ladder.
High-altitude work is often performed by climbing ladders, and if the ladder is not properly secured, it can wobble or tip over, leading to falls. Such accidents are particularly common on cylindrical structures like utility poles where the ladder only makes contact at a single point. Existing safety devices that use curved supports to lean the ladder against the structure have failed to fully secure the ladder, leaving risks unresolved.
This technology uses a horseshoe-shaped frame to wrap around the structure, tightened by fasteners at both ends, and includes a preliminary fixture for temporary stabilization before final tightening to prevent wobbling during installation. The support frame's base wraps around the ladder rungs and locks with a hinge to prevent detachment. Safety hooks can be attached to handles on both sides of the main frame, and a detachable backrest helps reduce the risk of falling backward. Applicable to utility pole maintenance, street light and traffic signal repair, and telecommunications equipment installation, it provides a stable, fixed platform that allows workers to sit while working on ladders that were previously unstable.
This technology is a plate-structured damper that uses a double-sided friction action plate inserted into a cover plate's cavity to provide primary damping through friction. Secondary elastic resistance is provided by an elastic plate inside the action plate's hollow space and elastic springs between the cavity's inner end and the action plate. Fasteners passing through the cover and elastic plates adjust friction and guide relative movement.
Conventional self-centering dampers for earthquakes and typhoons, which use shape-memory steel rods to connect friction plates, are difficult to adjust for restoring force after production. Because they convert vibration energy into frictional heat, they often fail to fully return to their original state. Furthermore, damaged rods are hard to replace or repair, making reuse difficult, and exposed operating parts pose safety risks.
This technology uses pre-compressed polyurethane cylinders as elastic springs to increase resistance. By providing clearance between the polyurethane elastic plate and the hollow space, resistance can be adjusted by changing the size, placement, and thickness of the plates. The cover plate consists of a pair of support plates and a connector; pressure bolts, nuts, and washers passing through slots in the support plates regulate friction, while complementary surface textures and spring pins prevent detachment and guide movement. Applicable to seismic retrofitting for schools and hospitals, bridge bearings, and plant piping, this damper returns to its original position after major earthquakes without residual deformation and allows for on-site damping performance adjustment via bolt tightening.
This invention was developed with support from the Ministry of Land, Infrastructure and Transport for the commercialization of multi-functional seismic vibration reduction devices for pilotis structures capable of withstanding a magnitude 7.0 earthquake.
This technology provides a tunnel information modeling framework and system where a framework configuration unit links drill-and-blast tunnel project data to multiple data models to create a BIM-based tunnel information model, and a project support unit manages tunnel processes and project information for each process using this model. The framework consists of a data source layer, multi-modeler, integration layer, analysis layer, and application layer.
IFC, the foundation of BIM, has primarily developed in the architectural sector, while research in civil engineering has focused on roads and bridges, leaving a significant gap in IFC expansion for tunnel construction. Existing IFC information exchange environments have also suffered from 3D object information loss and inaccurate data transmission. Drill-and-blast tunneling generates diverse data throughout the project lifecycle—such as borehole logs, geological maps, and blasting vibration records—which are still manually exchanged using traditional methods, limiting accurate information sharing among stakeholders.
In this technology, a multi-modeler links project data collected at the data source layer to five data models—ground surface/soil, drill-and-blast, geological rock, rock support, and concrete lining—to construct an IFC schema-based tunnel class. The data source layer collects geophysical surveys, drilling logs, blasting logs, ground vibration monitoring, and process/cost records across feasibility, design, and construction phases. Each model is divided into detailed classes such as rock bolts, shotcrete, wire mesh, lattice girders, and convergence monitoring points. Applicable to NATM mountain tunnels for roads and railways, blasting sections for subways and deep underground roads, and hydraulic power tunnels, it integrates scattered geological, blasting, and support data from investigation to completion, allowing clients, designers, and contractors to make face-mapping decisions based on the same information.
This invention was developed with support from the Ministry of Science and ICT for a digital-twin framework for earthworks.
This technology is a piezoelectric harvesting module for roads, consisting of a case with an upper surface that receives external forces like vehicle loads and an openable lower surface. Piezoelectric elements are attached to the underside of the top surface, and the module is embedded into the road. The lower surface features receiving grooves for the piezoelectric elements and cushioning material, while both surfaces are made of high-friction material to integrate seamlessly with the road pavement.
While piezoelectric harvesting efficiently converts even minor vibrations into electricity and functions in the dark, generating significant power previously required embedding generators directly beneath traffic paths. Installing these in roads typically required cutting the pavement, which damaged the road, shortened its lifespan, and necessitated frequent maintenance.
This technology features a design where the upper and lower surfaces are embedded in parallel, connected by an elastic vibration-generating member that creates vibrations from external forces, and a support member that transmits these vibrations. Multiple piezoelectric elements are mounted on the support member, spaced apart and parallel to the surface. The vibration-generating member is placed outside the support member and piezoelectric elements, deforming when the top surface is pressed to create vibrations. Suitable for high-traffic areas like highway toll booths, intersections, bus stops, and parking entrances, it integrates with the pavement to convert vehicle loads into power for road lighting or sensors without damaging the road surface.
This invention was developed with support from the Ministry of Trade, Industry and Energy for the development and demonstration of piezoelectric energy harvesters to utilize untapped road traffic energy.
This technology is a system and resulting acoustic diffusion structure that receives architectural structural data, plots points on a corresponding 2D plane, divides the plane into polygonal Voronoi cells, and designs a 3D acoustic diffusion structure using each cell as a base and a polygon with the same number of vertices as the top surface.
Interior materials for spaces requiring acoustic diffusion, such as concert halls and opera houses, must evenly disperse indirect sound to enhance clarity and diffusion. However, conventional acoustic diffusers have uniform surface shapes and areas, varying only in height. This leads to sound waves failing to scatter effectively and instead concentrating in specific directions.
This technology features a processor that sets a virtual vertex at a fixed height perpendicular to the base's center of gravity, draws virtual edges connecting to each base vertex, and then randomly selects heights within a set range for each vertex to determine the top surface vertices along those edges. The heights vary per vertex, the top surface is smaller than the base, and the structure can be designed as either concave or convex. Applicable to wall finishes in concert halls, opera houses, auditoriums, recording studios, and home theaters, it automatically creates reflective surfaces with varying sizes and slopes per cell, evenly scattering sound waves while generating unique design patterns every time.
This invention was developed with support from the Ministry of Education for the development of acoustic diffusers for performance venues using liquid acrylic mixtures.
This technology is a medical booth featuring a caster-mounted base with hinged ceiling, front, and side panels. It can be folded for storage, moved to where needed, and unfolded to create a treatment space. A positive-pressure unit with a filter is attached to the ceiling panel to maintain a sterile internal environment.
In hospitals, sterile medical procedures are typically performed in operating rooms or intensive care units. Because these spaces are limited, patients requiring simple procedures often face long wait times. This leads to the inefficient use of expensive operating room resources and increased patient wait times.
This technology features a hexahedral base with open front and bottom sections, containing a horizontal shelf that meets the folded extension. The ceiling panel rotates vertically relative to the base, the front panel rotates vertically relative to the ceiling, and the side panels rotate horizontally to unfold. Torque hinges at the connections allow for positioning at any angle. The side panels consist of two hinged sections that lock to the front panel when deployed, with access doors on the front or sides. Suitable for emergency rooms, outpatient clinics, infectious disease screening centers, and disaster relief sites, it allows for the setup of a sterile treatment space anywhere in a hospital within minutes, without needing an operating room, and can be folded for compact storage after use.
This technology is a bracket structure for traditional buildings, assembled by fixing bracket units—formed by interlocking first and second bracket arms with central, extended, and end-coupling sections via fixing grooves—onto a block unit featuring assembly grooves on its top.
Brackets, composed of components like column capitals, blocks, and bracket arms, transfer roof loads to columns and serve decorative purposes. Because these components are joined through interlocking, their precise dimensions are critical, traditionally requiring skilled craftsmen to carve and assemble them. Furthermore, changing the bracket dimensions necessitated creating entirely new components, leading to a lack of compatibility between parts.
This technology features protrusions at one end of each bracket arm and corresponding coupling grooves at the other, allowing for longitudinal extension, or stepped sections on the top and bottom of the coupling parts for overlapping. The block unit is created by inserting first and second fastening members in a cross-direction into a plate-type fixing member with paired outer fastening grooves, with the number of groove pairs matching twice the number of bracket arms. Applicable to new hanok construction, cultural heritage restoration, and traditional-style public buildings, this system allows for factory-produced standardized parts, enabling unskilled labor to assemble brackets and accommodating dimension changes by simply extending the bracket arms.
This invention was developed with support from the Ministry of Science, ICT and Future Planning for the reconstruction of traditional wooden roof structures and forms using digital construction technology and ecological design techniques.
This technology creates 3D BIM-GIS information using construction equipment data collected by multiple server modules to integrate and control equipment and construction sites. It analyzes work history, including active and idle time, by calculating time intervals, displacement, and rotation angles from GPS data on equipment operator terminals.
Existing construction equipment management technologies are limited to specific equipment, using NFC tags, Bluetooth, or GPS to track transport vehicle trips or route deviations, making it difficult to analyze and manage interconnected tasks within a single program. Operators receive limited information, preventing them from considering step-by-step work plans and reducing efficiency. Furthermore, the inability to utilize 3D spatial data, such as earthwork volumes or orthophotos, has restricted these systems to simple monitoring tasks like relaying, authentication, and location tracking.
This technology links 3D design models and site conditions to GIS maps to display equipment locations, temporary roads, work zones, and planned routes in real time, while automatically calculating work plans and target earthwork volumes using geofences drawn on the map. The geofence entry/exit management module determines if equipment is inside a zone by calculating the intersection of the GPS path with the geofence boundary, recording entry/exit times, identifying circulation routes via zone attributes, and cross-referencing CCTV license plate recognition data. Applicable to large-scale land development, industrial complexes, road/railway subgrade construction, and dam/landfill projects, it quantifies actual utilization and idle time for dump trucks and excavators to optimize dispatching and automatically detect unauthorized removal or route deviations.
This invention was developed with support from the Ministry of Land, Infrastructure and Transport for intelligent control platforms and big data-based optimal route navigation technology.
This technology is a composite beam that creates a closed section by attaching a bent steel inverted U-shaped cover to an open-top steel beam, and provides shear connection with slab concrete through steel anchors formed at each side-perforation aligned along the cover's sidewalls.
Composite beams made by filling concrete into channel-type open-section steel previously required separate shear connectors like stud bolts, steel plates, or rebar to resist shear forces between the steel and concrete. Open-section steel assembly composite beams had lower flexural rigidity than closed sections, while bent steel plate composite beams had limited concrete space, requiring reinforcement with tendons. Furthermore, long rebar or dowel bar shear connectors often interfered with deck plates, making installation difficult.
This technology features steel anchors designed with a narrow anchor neck protruding toward the center of the side-perforation and a wide anchor head at the end to ensure sufficient bearing projection area. There are two configurations: one where the perforation is made in a recessed part of the sidewall and the anchor is tilted outward, and another where it is made in a protruding part and the anchor is tilted inward. The cover can be installed at the same length as the steel beam or in shorter, spaced segments. Applicable to composite beam floors in offices and logistics facilities using deck plates, semiconductor and electronics factories with cleanrooms, and remodeling projects requiring lower floor heights, this system achieves both cross-sectional rigidity and shear connection through cover forming alone, eliminating the need for stud welding or long connectors that conflict with deck plates.
This invention was developed with support from the Ministry of Education for the development of parking lot construction methods using studless concrete-filled composite beams.
This technology is an offshore wind structure production method where high-strength concrete segments are joined one by one at an onshore facility to create an integrated tower. A guide frame is then set up offshore, steel pipe piles are driven into the seabed support layer to mount the foundation connection, and the completed tower, nacelle, and blades are installed on top.
Monopile foundations and steel hollow towers, commonly used in offshore wind, have low rigidity, making them susceptible to buckling. They also suffer from poor durability in saline marine environments, and their internal gusset connections are prone to fatigue, requiring frequent on-site repainting and weld inspections. Consequently, their service life is limited to around 20 years, resulting in low economic efficiency over the lifecycle. Alternative concrete towers have faced limitations due to unresolved issues regarding offshore production, installation, and member connection.
This technology involves placing an existing segment next to an external formwork fixed at the production site, inserting a rebar cage using a movable bottom formwork to connect it to the existing segment's rebar, and then inserting a movable internal formwork to pour and cure concrete, repeating the process to horizontally extrude new segments. The internal and bottom formworks return to their original positions each time, with formwork and rebar cage positions verified by surveying and voids prevented through compaction. Applicable to large-scale offshore wind farms in the Southwest Sea and Jeju, coastal demonstration sites, and intertidal projects, it minimizes offshore work and ensures a longer lifespan than steel towers through seamless, high-durability concrete towers.
This invention was developed with research support from the Ministry of Education, Science and Technology for the rapid construction of pre-fab, pre-stressed concrete offshore wind towers.
This technology is an inter-story vibration control device that draws cables from four circles fixed symmetrically to the upper and lower floors of a structure to a midpoint height, secures them with a cross-shaped connector, and inserts dampers between the cables and the connector to absorb vibrations in an X-shape.
Although small to medium-sized earthquakes occur consistently in Korea, seismic research has focused on large structures and new buildings, leaving few examples of seismic retrofitting for existing low-to-mid-rise buildings. Installing vibration dampers on exterior walls compromises aesthetics and spatial openness, while interior installation often requires increasing wall thickness to meet damping capacity requirements, creating constraints on cost and space utilization.
This technology consists of a piston rod with a disk-type friction member, a cylinder body with a larger inner diameter, a hollow cap through which the piston rod passes, an opposing cylinder cap, a spring between the friction member and the hollow cap, and silicone oil filled inside. When ground vibrations are transmitted through the cables, the spring elasticity allows the piston rod to move, reducing external forces, while the viscosity of the silicone oil flowing around the friction member prevents rapid spring deformation. The connector combines bar and double-bar types with a hinge and can be easily attached using hooks at both ends of the cables. It can be applied to seismic remodeling of existing low-to-mid-rise buildings like schools and government offices, pilotis-structured apartment buildings, and small commercial buildings, allowing for the addition of damping devices in narrow indoor inter-story spaces with a short construction period without thickening walls or altering the exterior.
This invention was developed with support from the Small and Medium Business Administration for the development of an improved X-type slim damper for the seismic retrofitting of public structures.
This technology involves factory-producing half-precast concrete beams featuring main reinforcement and upward shear connectors within a half-panel thinner than the total beam depth. End steel plates are attached to the sides of both ends, and removable side panels are attached to the center. These are installed on-site by mounting them onto columns. After placing the deck, slab concrete is poured over the half-panel, and the side panels are removed.
While PC construction is advantageous for shortening schedules and ensuring quality, the increasing size of beams and columns has led to heavier lifting weights and more frequent lifts, complicating production, transport, and installation, while making it difficult to ensure joint integrity. Existing PC beams that form beams and slabs together without formwork are heavy due to their solid concrete construction, increasing transport frequency and the cost of large lifting equipment. They also lack end reinforcement, limiting their shear resistance.
This technology uses polygonal pre-assembled columns composed of precast panels on each side and temporary fasteners for external assembly. The panels contain main reinforcement, vertical bars, exposed shear loops, and hoop bars with bent connection ends. Placing the beam ends, equipped with steel plates, onto these columns integrates the joints during concrete pouring. Suitable for warehouses, industrial centers, retail facilities, and apartment parking structures, it significantly reduces beam weight for smaller equipment, enhances shear and moment resistance via end plates, and eliminates the need for beam bottom formwork and shoring.
This technology generates a user attribute context vector from text prompts and user metadata such as gender, age, and region. It then inputs this vector, along with text and biomechanical vectors, into a diffusion-based motion generation model to produce personalized joint rotation sequences.
Existing 3D character motion generation methods often fail to reflect the gender, age, or regional characteristics of the user or character, making it difficult to create motions tailored to individual traits.
By incorporating motion styles specific to each attribute through user attribute context vectors and contrastive learning, this technology can be applied to personalized 3D character content to generate motions that align with specific user characteristics.
This patent portfolio consists of four family patents covering AI-based 3D motion generation technology developed by Bumblebee Co., Ltd. Technology transfer is available alongside the patents, and the sale price is negotiable. Please refer to the attached technical manual for detailed information.
