Description

Technical Field

[0001] This utility model relates to the field of seismic resistance technology in buildings, and in particular to a sliding structure for anti-buckling steel plate walls for seismic resistance in buildings. Background Technology

[0002] Buckling-resistance steel plate walls (SRCBs) are widely used in seismic structural design due to their excellent energy dissipation and lateral force resistance. However, current technologies still face the problem of failing to isolate vertical load transfer in SRCB node design. This is because when the SRCB is rigidly connected to the surrounding steel frame columns, the SRCB and the surrounding steel frame columns can share the vertical load. Especially under earthquakes or other loads, this vertical stress concentration can cause stiffness changes, leading to discrepancies and potential problems between the structural design and analysis results, thus affecting the designer's understanding of the structure's seismic performance. Utility Model Content

[0003] In order to solve the above problems, the present invention aims to provide a sliding structure for anti-buckling steel plate walls that is earthquake resistant in buildings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides a sliding structure for a buckling-resistance steel plate wall in earthquake-resistant buildings. It is characterized by comprising: a frame beam, a buckling-resistance steel plate wall, embedded steel columns, force-transfer beams, and a foamed material filling layer. The frame beam includes two horizontally arranged upper and lower frame beams, which are fixedly connected to the building. The buckling-resistance steel plate wall is located between the upper and lower frame beams. The buckling-resistance steel plate wall includes two vertically arranged steel frame columns and a corrugated steel plate connecting the two steel frame columns.

[0015] Compared with the prior art, the present invention has the following significant advantages:

[0016] This utility model relates to a sliding structure for seismic-resistant buckling-resistance steel plate walls. Through its sliding design, the steel plate wall and surrounding steel frame columns are not subjected to vertical loads, thus isolating the vertical load transfer, effectively reducing analysis bias, and improving seismic stability. The low-friction coefficient material layer and lubrication groove design reduce frictional resistance, making sliding smoother and more reliable. A foamed material filling layer is placed between the load-transfer beams and the frame beams, releasing the constraint between them. This utility model of a sliding structure for seismic-resistant buckling-resistance steel plate walls is suitable for newly built or renovated high-rise buildings, bridges, and other seismic-resistant structures.

[0022] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.

[0023] See Figure 1 This embodiment provides a sliding structure for a buckling-resistant steel plate wall for earthquake resistance, which includes: a frame beam 1, a buckling-resistant steel plate wall, an embedded steel column 4, a force transmission beam 5, and a foamed material filling layer 6.

[0024] The frame beam 1 consists of two horizontally arranged frame beams, one above the other. The frame beam 1 is connected and fixed to the building using conventional construction methods.

[0025] The buckling-restrained steel plate wall is located between the upper frame beam 1 and the lower frame beam 1. The buckling-restrained steel plate wall consists of two vertically arranged steel frame columns 2 and a corrugated steel plate 3 connecting the two steel frame columns 2. The buckling-restrained steel plate wall is rigidly connected to the lower frame beam 1 (i.e., the floor beam) using a welding process, which facilitates construction and installation. The weld thickness is 8 mm, effectively transferring horizontal shear force to the floor beam while ensuring the overall structural rigidity and stress coordination.

[0026] The embedded steel columns 4 include upper and lower vertically arranged embedded steel columns 4, which are welded to the frame beam 1. See also... Figures 3 to 5 The interior of the embedded steel column 4 is also equipped with a stiffening plate 9.

[0027] See Figure 1 and 2 The steel frame column 2 is a hollow square column. The upper and lower embedded steel columns 4 are inserted into the upper and lower ends of the steel frame column 2 respectively and are slidably connected to the steel frame column 2.

[0028] The embedded steel column 4 has a low-friction coefficient material layer 7 covering its sliding contact interface with the steel frame column 2. The low-friction coefficient material layer 7 is made of polytetrafluoroethylene (PTFE) or ultra-high molecular weight polyethylene (UHMWPE). In this embodiment, commercially available products are used for both PTFE and UHMWPE. The surface roughness of the low-friction coefficient material layer 7 is set to 0.2 μm to 0.8 μm to ensure good sliding performance. The low-friction coefficient material layer 7 has a sleeve structure, and the sliding contact interface of the embedded steel column 4 is nested with the low-friction coefficient material layer 7 to prevent detachment.

[0029] The steel frame column 2 has lubrication grooves on its surface at the sliding contact interface with the embedded steel column 4, for filling with lubricating grease. The lubricating grease is a solid lubricant or a durable lubricating oil. This reduces frictional resistance and gives the sliding contact interface a self-lubricating function.

[0030] Corrugated steel plate 3 serves as the main damping component. The thickness of corrugated steel plate 3 is 12 mm. Force transmission beams 5 are respectively provided on the upper and lower edges of corrugated steel plate 3, and the force transmission beams 5 are connected to corrugated steel plate 3.

[0031] See Figures 3 to 5 The two ends of the force transmission beam 5 are connected and fixed to the steel frame column 2. It has the following forms: the first type is shown in [reference needed]. Figure 3 The force transmission beam 5 is a square steel tube, and a steel plate is installed at its end. A steel plate 81 is installed at the connection between the end face of the force transmission beam 5 and the steel frame column 2. The force transmission beam 5 and the steel frame column 2 are welded and fixed to both sides of the steel plate 81. (See the second method.) Figure 4 The force transmission beam 5 is a square steel tube, and steel plates are installed at its ends. A steel plate 82 is installed on each of the two sides of the force transmission beam 5, and the edges of the steel plates 82 are welded and fixed to the steel frame column 2. (See the third type.) Figure 5 The force transmission beam 5 is an I-beam, and stiffening plates 83 are provided at the ends of the force transmission beam 5. The stiffening plates include obliquely arranged and symmetrically arranged stiffening plates.

[0032] A foamed material filling layer 6 is placed between the force-transmitting beam 5 and the frame beam 1 to release the constraint between the force-transmitting beam and the frame beam. The foamed material filling layer 6 is made of commercially available closed-cell polyurethane foam or high-strength foam plastic, which has good resistance to compressive deformation. The thickness of the foamed material filling layer 6 is 20 mm to 50 mm.

[0033] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
