A prefabricated seismic-resistant beam-column connection node structure

Abstract

This utility model discloses a prefabricated seismic-resistant beam-column connection node structure, specifically relating to the field of building structure technology. It includes a connecting column with a multi-faceted limiting mechanism on its outer side. The multi-faceted limiting mechanism includes two fixing frames, with a beam-column inserted into the inner side of each fixing frame. One side of each fixing frame is fixedly connected to the outer side of the connecting column, and two reinforcing ribs are fixedly connected to the outer side of each fixing frame. This utility model utilizes the insertion of the fixing frames into the beam-column connection to provide initial stiffness and shear resistance. Multiple guide strips are used to achieve multi-point frictional energy dissipation under earthquakes. Simultaneously, the clamps limit the high-strength bolts to prevent loosening or falling off during high-intensity earthquakes, ensuring the stability of the beam-column connection node. Combined with the guiding function of the guide columns for the insertion of the connecting square tube, even when there is a large deviation between the connecting column and the connecting square tube, automatic centering and precise positioning can be achieved during insertion, thereby improving on-site connection efficiency.

Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and more specifically, to a prefabricated earthquake-resistant beam-column connection node structure. Background Technology

[0002] Beams and columns generally refer to the columns used to support beams in a building, while the connecting node structure is the structure used to connect beams and supporting columns. It is a key component of steel structure. In steel structure system, the stiffness and strength of the nodes are important factors affecting the load-bearing capacity of steel structure.

[0003] The existing connection node structure has a rather complicated assembly process, which requires workers to spend a lot of time splicing and assembling it, thus interfering with the overall construction efficiency. In addition, the existing connection node structure has poor vibration damping effect, which makes the connection node structure prone to cracks or even direct breakage when encountering strong vibrations, thus posing certain safety hazards to users.

[0004] A search revealed that Chinese Patent No. CN219952224U discloses a prefabricated seismic-resistant beam-column connection node structure. This utility model has a better shock absorption effect, thereby avoiding cracks or even direct breakage of the connection node structure when encountering strong vibrations, thus effectively improving the safety of the device during use.

[0005] However, in actual use, when hoisting and installing the beams, workers need to support the beams to assist other workers in bolting the beams and connecting nodes. This step is prone to installation errors, affecting the stability of the beam-column connection. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a prefabricated seismic-resistant beam-column connection node structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A prefabricated seismic-resistant beam-column connection node structure includes a connecting column. A multi-faceted limiting mechanism is provided on the outer side of the connecting column. The multi-faceted limiting mechanism includes two fixing frames. A beam-column is inserted into the inner side of each fixing frame. One side of each fixing frame is fixedly connected to the outer side of the connecting column. Two reinforcing ribs are fixedly connected to the outer side of each fixing frame, with one side of each reinforcing rib fixedly connected to the outer side of the connecting column. Multiple reinforcing ribs are fixedly connected to the outer side of each fixing frame, with one side of each reinforcing rib fixedly connected to the outer side of the connecting column. Multiple guide strips are fixedly connected to the inner side of each reinforcing rib. Three high-strength bolts are inserted into the inner side of each fixing frame. A pad and a pad are slidably connected to the outer side of each high-strength bolt. The pads are symmetrically arranged on the outer side of the fixing frame. Three retaining seats are provided on one side of each retaining seat. A retaining slot is formed on one side of each retaining seat, and the inner side of each retaining slot engages with one end of a high-strength bolt. Two bolts are slidably connected to the inner side of each retaining seat, with one end of each bolt threadedly connected to the inner side of the pad. A connecting mechanism is provided inside the connecting column.

[0009] By adopting the above technical solution, the beams and columns can be quickly connected and aligned with the fixed frame through plug-in alignment. This simplifies the alignment operation between the beams and columns and the fixed frame at high altitudes, thereby reducing the hoisting and adjustment time and maintaining the efficiency of the beam-column connection.

[0010] As a further description of the above technical solution: the connecting mechanism includes two connecting plates, the inner side of the connecting plate is fixedly connected to the outer side of the connecting column, two guide columns are fixedly connected to the inner side of the connecting column, a connecting square tube is provided on the outer side of the connecting plate, a connecting plate is fixedly connected to one end of the connecting square tube, a high-strength bolt is inserted into the inner side of the connecting plate, and the outer side of the high-strength bolt is inserted into the inner side of the connecting plate.

[0011] By adopting the above technical solution, multiple guide posts are used to guide the connecting square tube, so that the connecting posts and connecting square tube can still be aligned even if there is a misalignment, and connecting plate one and connecting plate two can be easily connected and fixed by multiple high-strength bolts.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a multi-faceted limiting mechanism, compared with the existing technology, the fixed frame is used to connect with the beam and column. The connection provides initial stiffness and shear resistance. Multiple guide bars are used to perform multi-point friction on the beam and column to realize sliding friction energy dissipation under earthquake. The card seat is used to limit the high-strength bolt to prevent the bolt from loosening or falling off under high-intensity earthquake, and maintain the connection stability of the beam and column connection node.

[0014] 2. By setting up a connection mechanism, compared with the existing technology, the guide post guides the insertion of the connecting square tube, so that even if there is a large deviation between the connecting post and the connecting square tube, it can be automatically aligned and accurately positioned during the insertion process, thus speeding up the on-site connection.

One end of the bolts 10 is threadedly connected to the inside of the pad 2 12. The inside of the connecting column 1 is equipped with a connecting mechanism. The beam column 11 is inserted into the fixed frame 2, and multiple guide strips 5 inside the fixed frame 2 are used to perform multi-point friction on the upper and lower sides of the beam column 11. At the same time, the card slots 9 on one side of the three card seats 8 are used to engage the outside of the nut of the high-strength bolt 6, so that the high-strength bolt 6 remains tight during vibration.

[0024] Reference Figure 2 and Figure 3 As shown, the connecting mechanism includes two connecting plates 13. The inner side of the connecting plate 13 is fixedly connected to the outer side of the connecting column 1. Two guide columns 14 are fixedly connected to the inner side of the connecting column 1. A connecting square tube 15 is provided on the outer side of the connecting plate 13. A connecting plate 16 is fixedly connected to one end of the connecting square tube 15.
