DETAILED DESCRIPTION
[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0013] Please see Figures 1-3 The present invention provides the following technical solution: A prefabricated building beam-column quick-connection structure includes a main beam 100, crossbeams 200 on both the front and rear sides of the main beam 100, and connecting plates 300 on both the front and rear sides of the main beam 100. It also includes: Two fixing mechanisms 400 are used to fix the crossbeam 200 on the same side from the left and right. The two fixing mechanisms 400 are respectively set in the middle of the opposite sides of the two docking plates 300. The fixing mechanism 400 includes four mounting plates 401 distributed in a matrix. The four mounting plates 401 are respectively fixed on the left and right sides of the docking plate 300 on the same side. A bidirectional screw 402 is rotatably connected between the two upper mounting plates 401. The threads at both ends of the bidirectional screw 402 are opposite. Clamping plates 404 are threaded to both ends of the bidirectional screw 402. The two clamping plates 404 are used to clamp and fix the crossbeam 200 on the same side from the left and right. Rotating the bidirectional screw 402 can drive the two clamping plates 404 to move closer or further away synchronously, so as to achieve the left and right clamping of the crossbeam 200 on the same side. Two reinforcing structures 500 are used to fix the crossbeam 200 on the same side from the top and bottom. The reinforcing structures 500 are respectively set on the opposite sides of the two docking plates 300. The reinforcing structure 500 includes two symmetrical inclined plates 505. The two inclined plates 505 are fixed with movable plates 506 at their close ends. The two movable plates 506 are used to clamp and fix the crossbeam 200 on the same side from the top and bottom. They can flexibly adapt to crossbeams 200 with different widths and heights, solve the problem of poor adaptability of traditional structures, improve docking efficiency and connection stability, and prevent loosening and displacement during long-term use.
[0014] In this embodiment, please refer to Figure 1 The connecting plate 300 is U-shaped, and the two connecting plates 300 form a rectangular frame that fits over the main beam 100. The main beam 100 and the two connecting plates 300 are fixed together by bolts. The U-shaped connecting plate 300 has a larger contact area with the main beam 100, and the bolt fixing enhances the connection firmness and makes installation and disassembly convenient. The rectangular frame structure provides a stable installation foundation for the mounting plate 401 of the fixing mechanism 400 and the bracket 501 of the reinforcement structure 500, preventing shaking when the fixing components are subjected to force and ensuring the load-bearing capacity of the overall connecting structure.
[0015] In this embodiment, please refer to Figure 2An auxiliary rod 403 is fixed between the two mounting plates 401 below. The auxiliary rod 403 is slidably connected to the two clamping plates 404. The auxiliary rod 403 guides and limits the clamping plates 404 to prevent the clamping plates 404 from shifting circumferentially as the bidirectional lead screw 402 rotates, and ensures that the two clamping plates 404 always remain in a parallel clamping state.
[0016] Specifically, the bidirectional lead screw 402 and the auxiliary rod 403 are located above and below the crossbeam 200 on the same side, respectively. The crossbeam 200 and the two clamping plates 404 on the same side are fixed by bolts. The bidirectional lead screw 402 and the auxiliary rod 403 are arranged vertically to make the crossbeam 200 more evenly stressed and avoid deformation caused by unilateral stress. The secondary bolt fixing further strengthens the connection on the basis of clamping by the clamping plate 404, preventing the crossbeam 200 from separating from the clamping plate 404 under vibration or external force, significantly improving the fixation reliability in the left and right directions and extending the service life of the structure.
[0017] Furthermore, one end of the bidirectional lead screw 402 extends to the outside of the mounting plate 401 and is fixed with a knob 405. The outer wall of the knob 405 is integrally formed with several protrusions, which increases the friction between the knob 405 and the hand. Without the need for additional tools such as wrenches and screwdrivers, the knob 405 can be manually and quickly rotated to drive the bidirectional lead screw 402, simplifying the operation process.
[0018] In this embodiment, please refer to Figure 3 The reinforcement structure 500 also includes two sets of brackets 501 arranged in pairs. The two sets of brackets 501 are respectively fixed to the top and bottom of the side of the connecting plate 300 near the crossbeam 200 on the same side. The other end of the inclined plate 505 is fixed with a lifting plate 503. The lifting plate 503 is slidably connected between the two sets of brackets 501 on the same side, and the height of the movable plate 506 can be flexibly adjusted to adapt to crossbeams 200 of different thicknesses, thus enhancing the versatility of the structure.
[0019] Specifically, each set of brackets 501 is fixed with a limiting post 502 that passes through the movable plate 506 on the same side. The two movable plates 506 are fixed at both ends by bolts. The crossbeam 200 is clamped between the middle of the two movable plates 506. The limiting post 502 restricts the movement trajectory of the movable plate 506, preventing the movable plate 506 from shifting left or right when moving up and down, and ensuring that the movable plate 506 accurately fits the upper and lower surfaces of the crossbeam 200.
[0020] Furthermore, in each set of brackets 501, a spring 504 is installed between the bracket 501 away from the crossbeam 200 on the same side and the lifting plate 503 on the same side. The spring 504 is sleeved on the limit post 502 on the same side. The spring 504 provides a continuous elastic force, pushing the lifting plate 503 to move closer to the crossbeam 200, so that the movable plate 506 forms a flexible clamp on the crossbeam 200, which can buffer the vibration and impact during the use of the building.
[0021] In use, the prefabricated building beam-column quick-connection structure of this utility model involves fitting two U-shaped connecting plates 300 onto the main beam 100 to form a rectangular frame structure, and then fixing the main beam 100 to the two connecting plates 300 with bolts. The crossbeam 200 is moved to the designated positions on the front and rear sides of the main beam 100, so that the crossbeam 200 is in contact with the surface of the butt plate 300 and is located between the bidirectional screw 402 and the auxiliary rod 403 of the same side fixing mechanism 400, and is also located between the upper and lower movable plates 506 of the reinforcement structure 500. Manually rotate the knob 405 at one end of the bidirectional lead screw 402. Since the threads at both ends of the bidirectional lead screw 402 are in opposite directions, its rotation will drive the clamping plates 404 at both ends to move closer to each other along the auxiliary rod 403. After the two clamping plates 404 are tightly attached to the left and right sides of the crossbeam 200, the crossbeam 200 and the two clamping plates 404 are further fixed with bolts to complete the left and right clamping and positioning. During the placement of the crossbeam 200, it will compress the upper and lower symmetrical movable plates 506. The movable plates 506 drive the connected inclined plates 505 and lifting plates 503 to slide along the limiting post 502, while compressing the spring 504 sleeved outside the limiting post 502. The spring 504 generates an elastic reaction force, which is transmitted to the movable plates 506 through the lifting plate 503 and inclined plates 505, so that the two movable plates 506 tightly clamp the upper and lower surfaces of the crossbeam 200. Then, the left and right ends of the two movable plates 506 are fixed by bolts to complete the elastic reinforcement in the upper and lower directions.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
