Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to an assembled self-insulating steel plate shear wall. Background Art

[0002] Shear walls are important structural components in buildings that resist horizontal loads such as wind loads and earthquake loads. Common types include reinforced concrete shear walls, steel plate shear walls, and composite shear walls. Steel plate shear walls are widely used due to their high lateral stiffness and high horizontal bearing capacity. However, due to the high thermal conductivity of steel, their insulation effect is not ideal.

[0003] Building energy consumption accounts for about 30% of my country's total social energy consumption, and the energy consumption of envelope structures including shear walls accounts for more than 85% of the total building energy consumption. Therefore, how to reduce the energy consumption of buildings is an important issue in today's construction industry.

[0004] To improve thermal insulation performance, traditional steel plate shear wall structures often use external insulation, installing insulation panels on the outside of the shear wall to form an insulation layer. However, this type of external insulation often results in the panels falling off, leading to serious consequences such as falling objects.

[0005] Traditional steel plate shear walls are thin, and are prone to buckling and deformation during use, which can produce loud noises and a "breathing effect," affecting user experience. Welded stiffeners are often used to increase their buckling bearing capacity and reduce their "breathing effect." However, welding can produce enormous residual stresses, leading to initial defects and hindering the use of shear walls. Summary of the Invention

[0006] The purpose of the present invention is to provide an assembled self-insulating steel plate shear wall to solve the problem that the insulation plate will fall off and welding will generate huge residual stress, causing initial defects.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] An assembled self-insulating steel plate shear wall comprises a shear wall frame, shear walls, insulation material and connectors; the shear wall frame is a rectangular frame, two shear walls are arranged parallel and symmetrically inside the shear wall frame, and insulation material is filled between the two shear walls; the upper and lower ends of the shear walls are fixedly connected to the shear wall frame through connectors.

[0009] Furthermore, the shear wall frame includes frame columns and frame beams; two frame columns and two frame beams form a rectangular frame structure.

[0010] Furthermore, the frame columns and frame beams are both H-shaped steels.

[0011] Furthermore, the shear wall includes a plurality of channel steel subunits, which are arranged vertically or horizontally, and the channel steel subunits are connected by fasteners.

[0012] Furthermore, connection holes are evenly arranged on the flanges of the channel steel subunits, and the connection holes of adjacent channel steel subunits correspond to each other and are connected by fasteners.

[0013] Furthermore, the connecting piece is an angle steel.

[0014] Furthermore, connection holes are provided on both sides of the angle steel, and holes matching the connection holes are provided on the shear wall frame and the shear wall, and are connected by fasteners.

[0015] Furthermore, the thermal insulation material is made of rock wool, extruded board or EPS foam board.

[0016] Compared with the prior art, the present invention has the following technical effects:

[0017] The present invention embeds thermal insulation material inside the shear wall, reducing heat dissipation of the wall; at the same time, internal thermal insulation is adopted, which can effectively solve the safety hazard of thermal insulation board falling off caused by external thermal insulation.

[0018] The shear wall of the present invention adopts channel steel sub-units placed vertically or horizontally and spliced ​​by fasteners to form a steel plate shear wall with stiffening ribs, thereby reducing the residual stress caused by the welded stiffening ribs.

[0019] The shear wall of the present invention is composed of two shear walls, each of which is spliced ​​by several channel steel sub-units, and the two shear walls are symmetrically arranged to form a rectangular cavity, ultimately forming a closed cross-section with a high bearing capacity.

[0020] The welding workload of shear walls is small and the assembly level is high, which can improve construction efficiency and reduce construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

The beneficial effects of the present invention patent are: it has the advantages of high lateral force stiffness, high shear bearing capacity, and a high degree of assembly. It can also realize the integration of insulation and structure.

[0030] Specifically:

[0031] A prefabricated, self-insulating steel plate shear wall comprises a frame column 1, a frame beam 2, a shear wall 3, fasteners 4, angle steel 5, and insulation material 6. The shear wall 3 is composed of channel steel subunits arranged vertically or horizontally, each connected by fasteners 4. The shear wall 3 is connected to the frame column 1 via fasteners 4; the shear wall 3 is connected to the frame beam 2 via angle steel 5 and fasteners 4. The prefabricated shear wall comprises two shear walls 3 made of channel steel, symmetrically arranged to form a rectangular cavity. Insulation material 6 is placed within the rectangular cavity to provide self-insulation.

[0032] The flange of the frame column 1 is provided with a plurality of through holes, and the channel steel is also provided with a plurality of through holes. The position and size of the through holes of the channel steel and the frame column 1 are adapted, and the position and size of the through holes of the channel steel and the channel steel are adapted.

[0033] There are multiple through holes on the flange of the frame beam 2, and there are also multiple through holes on one limb of the angle steel 5. The position and size of the through holes of the angle steel 5 are adapted to the frame column beam 2; the other limb of the angle steel 5 is adapted to the position and size of the through holes of the channel steel of the shear wall 3 sub-unit.

[0034] The shape and size of the shear wall 3 are adapted to the shape and size of the interior formed by the frame columns 1 and the frame beams 2 .

[0035] The material of the thermal insulation material 6 is a lightweight thermal insulation material such as rock wool, extruded board, EPS foam board, etc.
