[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1-4 This utility model provides an assembly node for a prefabricated reinforced concrete frame structure beam, including a column 1, with a horizontal beam 2 on both sides of the column 1; a right-angle mounting plate is installed on both sides of the column 1, the right-angle mounting plate includes a horizontal plate 3 and a vertical plate 4, one end of the horizontal plate 3 is fixedly connected to the top of the vertical plate 4, and the included angle between the horizontal plate 3 and the vertical plate 4 is 90°.

[0030] A first shaped plate 5 is fitted onto the horizontal plate 3, and the tops of the two first shaped plates 5 are in contact with the bottom surfaces of the two horizontal beams 2 respectively; a second shaped plate 6 is fitted onto the vertical plate 4, and the outer walls of the two second shaped plates 6 are in contact with the two sides of the column 1 respectively.

[0031] Elastic buffer components are installed between the horizontal plate 3 and the horizontal beam 2, and between the vertical plate 4 and the column 1; a transverse reinforcing rib 7 is fixedly installed between the horizontal plate 3 and the vertical plate 4, and the first C-shaped plate 5 and the second C-shaped plate 6 are both fixedly connected to the transverse reinforcing rib 7.

[0032] The crossbeam 2, the horizontal plate 3 and the first C-shaped plate 5 are fixedly connected by fastening bolts 16, the two vertical plates 4 are detachably connected by fastening components, and the second C-shaped plate 6 and the column 1 are fixedly connected to the fastening components.

[0033] With this configuration, the present invention achieves a stable connection between the beam 2 and the column 1 by installing right-angle mounting plates on both sides of the column 1, and connecting the horizontal plate 3 and the vertical plate 4 of the right-angle mounting plates to the beam 2 and the column 1 respectively. In addition, with the first C-shaped plate 5, the second C-shaped plate 6, the fastening bolts 16, and the fastening components, the installation is not only convenient, but also effectively transfers the load, ensuring the integrity and load-bearing capacity of the frame structure, and greatly improving the safety of the structure.

[0034] The elastic buffer assembly installed between the horizontal plate 3 and the horizontal beam 2, and between the vertical plate 4 and the column 1, can play a role in buffering and shock absorption, reduce stress concentration at the joint, enhance the compressive strength of the joint, reduce the risk of joint failure, and extend the service life of the building. At the same time, the elastic buffer assembly makes the right-angle mounting plate connection method adjustable to a certain extent, which can adapt to certain construction errors and improve the applicability of the joint.

[0035] The present invention provides a transverse reinforcing rib 7 fixedly installed between the horizontal plate 3 and the vertical plate 4. At the same time, the first U-shaped plate 5 and the second U-shaped plate 6 are both fixedly connected to the transverse reinforcing rib 7, which enhances the structural strength and stability of the right-angle mounting plate itself, and further improves the integrity and stability of the entire assembly node, so that the node can maintain a good working condition when subjected to various loads.

[0036] This utility model adopts a prefabricated structure, in which each component can be prefabricated in the factory. On-site installation of the nodes can be completed with only simple assembly, which effectively shortens the construction cycle, reduces on-site work, and improves construction efficiency.

[0037] Further optimization of the scheme: the elastic buffer component includes two rubber blocks 8. Two rubber blocks 8 are installed on the top of the horizontal plate 3 and the side wall of the vertical plate 4. There is a gap between the two rubber blocks 8. A cavity 9 is provided inside the rubber block 8. Several elastic elements 10 are installed in the cavity 9. The top of the elastic element 10 is fixed to the inner top wall of the rubber block 8, and the bottom is fixed to the inner bottom wall of the rubber block 8.

[0038] The first C-shaped plate 5 is located within the interval, the second C-shaped plate 6 is located within the interval, and the column 1, beam 2, horizontal plate 3 and vertical plate 4 are all in contact with the outer wall of the rubber block 8.

[0039] Two rubber blocks 8 installed on the top of the horizontal plate 3 and the side wall of the vertical plate 4 form a buffer layer between the horizontal beam 2 and the horizontal plate 3, and between the column 1 and the vertical plate 4. When the node is subjected to load, the rubber blocks 8 will undergo elastic deformation. Since the rubber material has good flexibility and elasticity, it can absorb some of the impact energy and reduce the force directly transmitted to key structural components such as the horizontal beam 2 and the column 1, thereby reducing the stress concentration at the node.

[0040] The cavity 9 inside the rubber block 8 and the several elastic elements 10 installed inside the cavity 9 further enhance the buffering effect. When the rubber block is squeezed or stretched, the spring will also undergo elastic deformation. During the deformation process, the elastic potential energy inside the spring changes, storing some energy. When the load decreases or disappears, the spring will return to its original shape, releasing the stored elastic potential energy and pushing the rubber block to reset. This dual buffering mechanism enables the elastic buffer component to absorb and consume energy more effectively, greatly improving the compressive strength of the node.

[0041] In a further optimized design, a diagonal support rod 11 is fixedly installed at the end of the horizontal plate 3 away from the vertical plate 4, and the bottom of the diagonal support rod 11 is fixedly connected to the end of the vertical plate 4 away from the horizontal plate 3.

[0042] In a further optimized design, a first through hole 12 is provided on each of the two opposite side walls of the second C-shaped plate 6, and a second through hole 13 is provided on the vertical plate 4. The fastening assembly includes a screw 14, which passes through the first through hole 12, the second through hole 13 and the column 1. Nuts 15 are threaded to both ends of the screw 14, and the two nuts 15 abut against the outer walls of the two second C-shaped plates 6 respectively.

[0043] After the screw 14 passes through these holes, the two ends are threaded with nuts 15. By tightening the nuts 15, the screw 14 is tightly connected to the second C-shaped plate 6, the vertical plate 4, and the column 1. The two nuts 15 abut against the outer walls of the two second C-shaped plates 6 respectively, generating sufficient preload to ensure the firmness of the connection. Due to the threaded connection of the screw 14 and nuts 15, when it is necessary to repair the node, replace parts, or perform other operations, it is only necessary to loosen the nuts 15 to pull the screw 14 out of the hole, thereby separating the vertical plate 4 from the column 1. This is convenient and quick, and improves the maintainability and flexibility of the node.

[0044] The design was further optimized by using springs for the elastic element 10, with several springs arranged at equal intervals.

[0045] The scheme is further optimized by adding two diagonal support rods 11. The tops of the two diagonal support rods 11 are fixed to the bottom sides of the horizontal plate 3. The two diagonal support rods 11 can provide stable support force to the horizontal plate 3 from both sides, preventing the horizontal plate 3 from being subjected to eccentric force or torsion when bearing load, and ensuring the force balance and structural stability of the right-angle mounting plate.

[0046] Two diagonal support rods 11 are distributed on both sides of the bottom surface of the horizontal plate 3, which can distribute the load transmitted by the horizontal beam 2 more evenly to the vertical plate 4, avoid local stress concentration, make the stress distribution inside the right-angle mounting plate more reasonable, and improve the overall stability of the node.

[0047] Further optimization of the scheme: the angle between the inclined support rod 11 and the horizontal plate 3 is 30° to 60°, and in this embodiment, it is preferably 45°. According to the principle of mechanics, at this time, the components of force of the inclined support rod 11 in the horizontal and vertical directions are equal, which can achieve the best mechanical balance state, so that the inclined support rod 11 can play a more efficient supporting role, further optimize the transmission path of internal forces of the node, and improve the stability of the structure.
