Description

Technical Field

[0001] This utility model belongs to the field of beam-column joint reinforcement technology, specifically relating to a steel structure portal beam-column joint reinforcement structure. Background Technology

[0002] Compared to other structural forms in building engineering, steel structures have advantages such as ease of construction, convenient transportation, light weight, high strength, good seismic performance, good plasticity and toughness, and aesthetic appeal. High-precision steel components are mass-produced in metal structure factories and then transported to the construction site for installation and assembly, which has promoted the design of modern steel structure buildings. However, the load-bearing capacity at the assembled beam-column joints is relatively concentrated. If the structural stress performance at the connection point is not strong, the beam-column joint is prone to deformation, which in turn affects the stability of the entire building structure. To address the above problems, Chinese Patent Application No. CN202420488694.7 discloses a steel structure portal beam-column joint reinforcement structure, aiming to solve the technical problems of difficulty in installing T-shaped plates and lack of integrity between T-shaped plates and beam-column joints in the prior art. It mainly includes a T-shaped plate, which includes a web for relatively fixing at the corresponding connection between the steel beam and the beam-column, and a flange perpendicular to the web and whose corresponding end is relatively fixed to the steel beam; the flange end is connected to the steel beam by bolts. In this application, the T-shaped plate is connected to the beam-column joint and the steel beam through a combination of welding and bolting, thereby strengthening the integrity of the connection between the T-shaped plate and the steel beam and the beam-column joint, and reducing the installation difficulty of the T-shaped plate.

[0003] While the device in the aforementioned patent can improve the deformation capacity and load-bearing capacity at the joint to a certain extent, it requires welding and fixing the T-shaped plate to the beam and column during installation and use. This usually requires operators to use a welding gun to weld and fix it. Moreover, if welding is done in a single time, the welding quality is easily poor, which will affect the strengthening effect of the joint. Multiple welding is usually required until the T-shaped plate and the beam and column are stably fixed and connected. Therefore, the existing technology has the problem of inconvenience in the installation process of the joint reinforcement structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel structure portal beam-column joint reinforcement structure, which solves the problem of inconvenient installation process of the joint reinforcement structure in the existing technology.

Then, the first and second plates in each angle area between the column and the beam are connected through the connecting parts. After all the first and second plates are connected, the first and second sliding sleeves self-lock to form a stable structure, completing the assembly of the beam-column joint reinforcement structure. The assembly process is simple and convenient, and there is no need to drill holes in the beam and column, avoiding damage to the beam or column caused by drilling.

[0030] This combination Figures 1 to 3 This describes an embodiment of a steel portal beam-column joint reinforcement structure. Specifically, the steel portal beam-column joint reinforcement structure is constructed as a split structure, comprising components such as a first sliding sleeve 100, a second sliding sleeve 200, a first strip plate 300, a second strip plate 400, and connecting parts. Before the crossbeam 800 and the column 900 are assembled and fixed, the first strip plate 300 and the second strip plate 400 are disassembled and separated. The first sliding sleeve 100 is fitted onto the crossbeam 800, and the two second sliding sleeves 200 are slidably fitted onto the column 900. Then, the crossbeam 800 is fixed to the column 900 by welding or other means, with the crossbeam 800 located between the two second sliding sleeves. Between 200; after the beam 800 and column 900 are fixed, push the first sliding sleeve 100 and the second sliding sleeve 200 to adjust their positions. Then, the first plate 300 and the second plate 400 in each angle area between the column 900 and the beam 800 are connected through the connecting part. After all the first plates 300 and the second plates 400 are connected, the first sliding sleeve 100 and the second sliding sleeve 200 self-lock to form a stable structure, completing the assembly of the beam-column joint reinforcement structure. The assembly process is simple and convenient, and there is no need to drill holes in the beam 800 and the column 900, avoiding damage to the beam 800 or the column 900 caused by drilling.

[0031] Please refer to Figures 1 to 3 The steel portal beam-column joint reinforcement structure includes a first sliding sleeve 100 and a second sliding sleeve 200.

[0032] The first sliding sleeve 100 is slidably mounted on the crossbeam 800. The first plate 300 is rotatably hinged to both the upper and lower ends of the first sliding sleeve 100. The first plate 300 can rotate in a vertical plane parallel to the central axis of the crossbeam 800.

[0033] There are two second sliding sleeves 200. Both second sliding sleeves 200 are slidably mounted on the column 900, and the two second sliding sleeves 200 are located at the upper and lower ends of the crossbeam 800 respectively. A second plate 400 is rotatably hinged to the side of the second sliding sleeve 200 that is close to the first sliding sleeve 100. The second plate 400 can rotate in a vertical plane parallel to the central axis of the crossbeam 800.

[0034] The first plate 300 and the second plate 400 within any included angle area between the column 900 and the beam 800 are detachably connected by a connecting part;

[0035] Before assembling and fixing the crossbeam 800 and the column 900, the first plate 300 and the second plate 400 are disassembled and separated. The first sliding sleeve 100 is fitted onto the crossbeam 800, and the two second sliding sleeves 200 are slidably fitted onto the column 900. Then, the crossbeam 800 is fixed to the column 900 by welding or other methods, with the crossbeam 800 positioned between the two second sliding sleeves 200. After the crossbeam 800 and the column 900 are fixed, the first sliding sleeve 100 and the second sliding sleeve 200 are pushed to adjust their positions. Then, the first plate 300 and the second plate 400 in each angle area between the column 900 and the beam 800 are connected by the connecting part. After the first plate 300 and the second plate 400 are connected, the first sliding sleeve 100 and the second sliding sleeve 200 self-lock to form a stable structure, thus completing the assembly of the beam-column joint reinforcement structure. The assembly process is simple and convenient, and there is no need to drill holes in the beam 800 and the column 900, avoiding damage to the beam 800 or the column 900 caused by drilling.

[0036] A pair of symmetrically placed first ear plates 500 are fixed at both the upper and lower ends of the first sliding sleeve 100. A horizontally placed first rotating shaft 501 is fixedly connected between the two first ear plates 500 at either end. The first rotating shaft 501 is perpendicular to the vertical plane where the central axis of the crossbeam 800 is located. One end of the first strip plate 300 is rotatably sleeved on the first rotating shaft 501 on the corresponding side, so that the tilt angle of the first strip plate 300 can be adjusted around the first rotating shaft 501.

[0037] A pair of second ear plates 600 are fixed on the side of the second sliding sleeve 200 near the first sliding sleeve 100. A second rotating shaft 601 is fixed between the two second ear plates 600 of any second sliding sleeve 200. The second rotating shaft 601 is placed coaxially with the first rotating shaft 501. One end of the second strip plate 400 is rotatably sleeved on the corresponding second rotating shaft 601 so as to rotate the second strip plate 400 around the second rotating shaft 601 to adjust the tilt angle.

[0038] The first plate 300 and the corresponding second plate 400 are both placed in a staggered manner, and any side wall of the first plate 300 and the second plate 400 that is perpendicular to the central axis of the first rotating shaft 501 is in the same plane; during connection and installation, the side wall of one end of the first plate 300 and the corresponding second plate 400 coincide, so that the connecting part can connect and fix them.

[0039] The first plate 300 has a first through hole 301, and the second plate 400 has a second through hole 401. The diameters of the first through hole 301 and the second through hole 401 are equal, and both the first through hole 301 and the second through hole 401 are placed coaxially with the first rotating shaft 501.

[0040] Each connecting part includes a bolt 700, which passes through the first through hole 301 and the second through hole 401. One end of the bolt 700 is provided with a nut 701, and the other end of the bolt 700 is fitted with a threaded nut 702. The first plate 300 and the second plate 400 are located between the nut 701 and the nut 702. When the first through hole 301 and the second through hole 401 are placed on the same axis, the bolt 700 is inserted into them, and then the nut 702 is installed on the other end of the bolt 700 and tightened to complete the installation connection between the first plate 300 and the second plate 400.

[0041] To improve the connection strength between the first plate 300 and the second plate 400, multiple first through holes 301 and multiple second through holes 401 are provided. The multiple first through holes 301 are evenly distributed along the axial direction of the first plate 300, and the multiple second through holes 401 are evenly distributed along the axial direction of the second plate 400. The hole spacing between two adjacent first through holes 301 is equal to the hole spacing between two adjacent second through holes 401. A connecting part can be provided at any first through hole 301 or second through hole 401 where the central axis coincides. The connection strength is improved by providing multiple connecting parts.

[0042] Simultaneously, the positions of the first sliding sleeve 100 and the second sliding sleeve 200 can be adjusted by sliding as needed, and the tilt angles of the first plate 300 and the second plate 400 can be adjusted by rotating, so as to selectively control the length of the overlapping part of the first plate 300 and the second plate 400, and thus selectively control and adjust the number of the first through hole 301 and the second through hole 401 that overlap the central axis as needed.

[0043] Two nuts 702 are provided at the ends of bolts 700 away from nuts 701; by setting double nuts 702, the possibility of bolts 700 and nuts 702 loosening is reduced, and the stability of the connection between the first plate 300 and the second plate 400 is further improved.
