Description

Technical Field

[0001] This application relates to the field of building beam-column connection device technology, and in particular to a modular building beam-column connection device for quick locking. Background Technology

[0002] In the field of modular building construction, the on-site connection and assembly of building beams and columns is a critical construction process. Currently, most existing modular building beams and columns use traditional connection methods such as welding, on-site drilling and pre-embedded bolts, and rigid flange docking. These conventional beam-column connection structures have many defects: they lack self-adaptive quick-locking clamping structures, elastic self-locking and limiting guide structures, low beam-column insertion alignment accuracy, and cannot achieve automatic locking after insertion. They also require a large number of additional auxiliary reinforcement components, occupying a large installation space, and have poor component versatility, making them unsuitable for standardized rapid assembly of modular beams and columns of different specifications. Furthermore, the connection structure lacks dedicated limiting positioning and secondary reinforcement structures, making beams and columns prone to displacement and misalignment after assembly. The overall connection sealing and structural integrity are insufficient, and the seismic resistance and load-bearing performance cannot meet the usage standards of high-rise and prefabricated modular buildings. Summary of the Invention

[0003] This application aims to address the technical problems of existing modular building beams and columns, which mostly adopt welding, pre-embedded bolts, and flange connection methods, lacking quick locking, elastic self-locking and precise limiting structures, resulting in cumbersome installation, poor versatility, easy misalignment during assembly, and overall load-bearing and seismic performance that cannot meet the high standards of prefabricated buildings. The application provides a modular building beam and column connection device with quick locking.

[0004] This application adopts the following technical means to solve the technical problem: a modular building beam-column connection device with fast locking, including a connection mechanism, a beam mechanism and a beam-column mechanism; The connecting mechanism includes a connecting frame, with connecting ports at both ends. A rotating shaft passes through the front of the connecting frame. An upper locking plate and a lower locking plate are movably connected inside the connecting ports. Locking grooves are provided at the bottom of the upper locking plate and the top of the lower locking plate. A telescopic spring is installed between the upper locking plate and the lower locking plate. The beam mechanism includes a beam body installed inside the connection port; The beam-column mechanism includes a beam-column body installed inside the connection port.

[0005] Preferably, the connecting frame is threaded with fixing bolts on one side and at the bottom, and the fixing bolts pass through the connecting frame and the limiting block.

[0006] Preferably, the bottom of the upper locking plate and the top of the lower locking plate are integrally formed with a connecting plate on the side away from the locking groove, and the connecting plate is rotatably connected to the rotating shaft.

[0007] Preferably, the inner wall of the connection port is integrally formed with a limiting block, and four limiting blocks are provided, which are arranged symmetrically in pairs.

[0008] Preferably, the top and bottom of both ends of the crossbeam body are provided with crossbeam slots, and the front and back of both ends of the crossbeam body are integrally formed with crossbeam locking plates.

[0009] Preferably, four crossbeam locking plates are provided, and the four crossbeam locking plates have the same shape and are triangular in structure.

[0010] Preferably, a mounting plate is welded to the bottom of the main beam-column body, and mounting openings are provided at the four corners of the top of the mounting plate.

[0011] Preferably, beam and column slots are provided on both sides of the top of the beam and column body, and beam and column locking plates are integrally formed on the front and back of the top of the beam and column body.

[0012] Preferably, there are two beam-column slots, and the inner width of the two beam-column slots is adapted to the outer width of the limiting block.

[0013] This application provides a modular building beam-column connection device with quick locking, which has the following advantages: 1. This type of quick-locking modular building beam-column connection device allows direct connection of the main beam / column body and the main beam body via the connection ports at both ends of the connecting frame. It utilizes beam-column slots, beam slots, and limiting blocks for quick alignment and guidance. During the insertion process, the beam-column locking plate and beam locking plate directly press against the upper and lower locking plates. The locking plates rotate around the rotation axis and compress the telescopic spring. After assembly, the telescopic spring automatically resets, driving the upper and lower locking plates to close, allowing the locking plates to automatically engage with the locking slots and complete self-locking. No additional manual snapping or tightening operations are required. The assembly process is simple and quick, eliminating the tedious procedures of on-site welding, drilling for alignment, and tightening multiple bolts one by one. This significantly shortens the on-site assembly period for modular building beams and columns and reduces the intensity of manual labor.

[0014] 2. This type of quick-locking modular building beam-column connection device, by setting four symmetrical limiting blocks in pairs on the inner wall of the connection port, and with the inner width of the beam-column slot matching the outer width of the limiting blocks, and the crossbeam slot precisely fitting with the limiting blocks, can provide radial and axial bidirectional limiting constraints on the main body of the beam-column and the main body of the crossbeam, effectively limiting the left-right, up-down, and front-back displacement of the beam-column; at the same time, the triangular crossbeam locking plate and the beam-column locking plate cooperate with the locking groove to further limit the rotation and movement between the beam and the column. Compared with existing connectors without dedicated limiting structures, this device has higher alignment accuracy and better overall integrity after assembly, avoiding the problems of beam-column connection misalignment and loosening from the structural root.

[0015] 3. This type of quick-locking modular building beam-column connection device employs a dual-protection structure of elastic self-locking and fixed bolt reinforcement. Firstly, the elastic clamping force of the telescopic spring ensures that the upper and lower locking plates remain in constant contact, maintaining a continuous locking state and preventing loosening over long-term use. Secondly, fixed bolts on the sides and bottom of the connecting frame penetrate the connecting frame and the limiting block, with the ends pressing against the main beam and column body, achieving secondary locking reinforcement. Compared to traditional single bolt connections or welding connections, this device significantly improves shear, bending, and torsional resistance, resulting in uniform stress distribution at the connection, stronger load-bearing capacity, and excellent seismic stability, meeting the heavy-load and seismic requirements of high-rise buildings and prefabricated modular buildings.

[0023] Reference Appendix Figure 1 - Figure 7 This application provides a technical solution: a modular building beam-column connection device for quick locking, including a connection mechanism 1, a beam mechanism 2 and a beam-column mechanism 3; The connecting mechanism 1 includes a connecting frame 101. Both ends of the connecting frame 101 are provided with connecting ports 102. A rotating shaft 104 passes through the front of the connecting frame 101. An upper locking plate 106 and a lower locking plate 107 are movably connected inside the connecting ports 102. Locking grooves 108 are provided at the bottom of the upper locking plate 106 and the top of the lower locking plate 107. A telescopic spring 109 is installed between the upper locking plate 106 and the lower locking plate 107. The crossbeam mechanism 2 includes a crossbeam body 201 installed inside the connection port 102; The beam-column mechanism 3 includes a beam-column body 301 installed inside the connection port 102.

[0024] Furthermore, the connecting frame 101 is threaded with fixing bolts 103 on one side and bottom. The fixing bolts 103 pass through the connecting frame 101 and the limiting block 105. By arranging fixing bolts 103 on the side and bottom of the connecting frame 101, and the fixing bolts 103 passing through the connecting frame 101 and the limiting block 105, after assembly, the fixing bolts 103 are tightened so that their ends press against the limiting block 105 and abut against the main body of the crossbeam 201 and the main body of the beam and column 301, thereby achieving secondary tightening and reinforcement, preventing the crossbeam and the beam and column from loosening or shifting, and improving the stability and firmness of the overall connection structure.

[0025] Furthermore, a connecting plate 110 is integrally formed on the bottom of the upper locking plate 106 and the top of the lower locking plate 107 away from the locking groove 108. The connecting plate 110 is rotatably connected to the rotating shaft 104. The upper locking plate 106, the lower locking plate 107 and the rotating shaft 104 are rotated together by the connecting plate 110. When the beam-column locking plate 305 and the crossbeam locking plate 203 are squeezed between the upper locking plate 106 and the lower locking plate 107, the upper locking plate 106 and the lower locking plate 107 can rotate flexibly around the rotating shaft 104 with the help of the connecting plate 110, so as to realize automatic opening and closing and avoidance, and provide a rotating structural basis for elastic locking.

[0026] Furthermore, the inner wall of the connection port 102 is integrally formed with limiting blocks 105. Four limiting blocks 105 are provided, and the four limiting blocks 105 are symmetrically arranged in pairs. By setting four limiting blocks 105 symmetrically arranged in pairs on the inner wall of the connection port 102, the crossbeam body 201 and the beam-column body 301 inserted into the connection port 102 can be limited and guided in multiple directions, restricting the radial offset and circumferential rotation of the crossbeam and the beam-column, ensuring accurate alignment during insertion and assembly, and improving the assembly regularity and structural integrity.

[0027] Furthermore, the top and bottom of both ends of the crossbeam body 201 are provided with crossbeam slots 202, and the front and back of both ends of the crossbeam body 201 are integrally formed with crossbeam locking plates 203. The crossbeam slots 202 provided at the ends of the crossbeam body 201 can be aligned and fitted with the limiting block 105 to realize the quick insertion and positioning of the crossbeam body 201; at the same time, the crossbeam locking plates 203 can be inserted into the locking grooves 108 of the upper locking plate 106 and the lower locking plate 107 to realize the quick locking and fixing of the crossbeam body 201 and the connecting mechanism 1.

[0028] Furthermore, four crossbeam locking plates 203 are provided, and the four crossbeam locking plates 203 are identical in shape and have a triangular structure. By setting the four crossbeam locking plates 203 of the same specification into a triangular structure, the triangular structure has the characteristics of stable force and good guidance. When inserted, it can be smoothly squeezed between the upper locking plate 106 and the lower locking plate 107. After being locked into the locking groove 108, it is not easy to slip out, thereby improving the reliability of locking and the resistance to force.

[0029] Furthermore, an installation plate 302 is welded to the bottom of the beam-column body 301. Installation openings 303 are provided at the four corners of the top of the installation plate 302. By welding and fixing the installation plate 302 to the bottom of the beam-column body 301, fastening connectors can be passed through the installation openings 303 at the four corners of the installation plate 302 to fix the installation plate 302 to the foundation installation surface, thereby realizing the ground-mounted fixed installation of the beam-column body 301. The installation is convenient and the fixation is reliable.

[0030] Furthermore, beam and column slots 304 are provided on both sides of the top of the beam and column body 301. Beam and column locking plates 305 are integrally formed on the front and back of the top of the beam and column body 301. The beam and column slots 304 on both sides of the top of the beam and column body 301 can be inserted and limited with the limiting block 105 to realize the quick alignment and connection between the connecting frame 101 and the beam and column body 301. The beam and column locking plate 305 can be inserted between the upper locking plate 106 and the lower locking plate 107 and locked with the locking groove 108 to complete the self-locking connection between the beam and column body 301 and the connecting frame 101.

[0031] Furthermore, two beam-column slots 304 are provided, and the inner width of the two beam-column slots 304 is adapted to the outer width of the limiting block 105. By setting the inner width of the two beam-column slots 304 to match the outer width of the limiting block 105, the limiting block 105 can be accurately embedded into the beam-column slot 304, achieving clearance fit limiting, avoiding shaking or misalignment after the connecting frame 101 is sleeved, and ensuring the coaxiality and assembly accuracy of the beam-column connection.

[0032] Working principle: When using the quick-locking modular building beam and column connection device, first place the mounting plate 302 at the bottom of the beam and column body 301 in the beam and column mechanism 3 at the preset installation position, and use fasteners to pass through the installation holes 303 at the four corners of the mounting plate 302 for locking and fixing, so as to achieve a stable assembly of the beam and column body 301 with the foundation ground.

[0033] Subsequently, the connecting frame 101 of the connecting mechanism 1 is sleeved on the outer side of the top of the beam-column body 301 through the end connecting port 102, so that the limiting block 105 on the inner wall of the connecting port 102 is correspondingly inserted into the beam-column slot 304 on both sides of the beam-column body 301, thereby realizing the radial limiting and positioning of the connecting frame 101 and the beam-column body 301; at the same time, the beam-column locking plates 305 on the front and rear sides of the top of the beam-column body 301 are inserted into the gap between the upper locking plate 106 and the lower locking plate 107 inside the connecting port 102.

[0034] As the connecting frame 101 continues to slide downwards, the beam-column locking plate 305 presses against the upper locking plate 106 and the lower locking plate 107. The two locking plates rotate relative to each other around the rotation axis 104 via the connecting plate 110, while simultaneously compressing the telescopic spring 109 arranged between them. When the connecting frame 101 is assembled in place, the compressed telescopic spring 109 generates an elastic restoring thrust, driving the upper locking plate 106 and the lower locking plate 107 to close towards each other, causing the beam-column locking plate 305 to engage in the locking groove 108 on the inner side of the locking plate, thus completing the self-locking of the beam-column body 301 and the connecting frame 101.

[0035] Next, the main body 201 of the crossbeam mechanism 2 is inserted into the side connection port 102 of the connecting frame 101 for assembly, so that the crossbeam slot 202 at the end of the main body 201 is aligned and fitted with the limiting block 105 to achieve the positioning of the main body 201; the crossbeam locking plates 203 on the front and rear sides of the end of the main body 201 are simultaneously embedded into the locking slots 108 of the upper locking plate 106 and the lower locking plate 107, and the locking and limiting are achieved by the elastic pressing action of the telescopic spring 109.

[0036] Finally, tighten the fixing bolts 103 on the side and bottom of the connecting frame 101 so that the ends of the fixing bolts 103 are pressed against the limiting block 105 and abut against the main body of the beam 201 and the main body of the beam and column 301 respectively, forming a secondary reinforcement constraint; the whole assembly achieves the assembly effect of quick alignment, automatic locking and stable connection between the main body of the modular building beam 201 and the main body of the beam and column 301 through the combination of plug-in positioning, elastic self-locking and bolt-assisted reinforcement.

[0037] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
