Description

Technical Field

[0001] The utility model belongs to the technical field of reinforced concrete wall panels, in particular to a steel plate supporting structure of a shear wall with built-in steel support. Background Art

[0002] The shear wall supported by the built-in steel plate is a prefabricated and assembled lateral force resisting component with steel plate as the basic support and reinforced concrete wall panel as the outer cover. It is only connected to the steel frame at the supporting node, and a gap is left between the wall panel and the frame, so the force is clear and the construction is convenient.

[0003] The shear wall supported by the embedded steel plate has large ultimate deformation and good ductility. Its true shear strength is much greater than the calculated value, providing additional bearing capacity and later anti-lateral displacement stiffness for the earthquake resistance of high-rise steel structures. In most cases, when the inter-story displacement is about 0.8% of the story height, the steel plate participates in the support buckling and the bearing capacity decreases. This value is larger than that of ordinary reinforced concrete walls. Therefore, in order to provide the embedded steel plate with an auxiliary support force when the shear wall is deformed, so as to improve the overall stability of the shear wall supported by the embedded steel plate, a steel plate support structure of the embedded steel support shear wall is designed. The structure supports the steel plate by means of concave panels, support plates and perforated limit plates. At the same time, the connection structure provides a tensioning driving force between the two steel plates, so that the embedded steel plate can obtain an auxiliary support force when the shear wall is deformed, so as to improve the overall stability of the shear wall supported by the embedded steel plate.

The two hole limiting plates 6 are fixedly connected to the concave heads 8 on the opposite sides. Example 2

[0025] Figure 1-5The steel plate support structure of the built-in steel support shear wall of an embodiment of the present invention is shown, which includes: a limit seat 2 fixedly connected to the top of the inner cavity of the support shear wall 1 by bolts: the left and right sides of the inner cavity of the limit seat 2 are rotatably connected to steel plates 3, the opposite sides of the two steel plates 3 are provided with rectangular grooves, the bottoms of the two steel plates 3 are rotatably connected to concave panels 4, the bottom of the inner cavity of the support shear wall 1 is slidably connected to two support plates 5, the opposite sides of the two support plates 5 are welded with open hole limit plates 6, a connecting structure 7 is provided between the two steel plates 3, and the surface of the concave panel 4 is embedded in the open hole limit plate 6 And the inner cavity of the concave head 8, through the setting of the concave head 8, the contact area between the opening limit plate 6 and the concave panel 4 can be expanded, so that the support plate 5 and the opening limit plate 6 can obtain a better fixing effect when supporting the steel plate 3. A through hole is opened at the bottom of the inner cavity of the supporting shear wall 1, and the inner cavity of the through hole is slidably connected with an expansion tube 9, and the inner cavity of the expansion tube 9 is slidably connected with a countersunk bolt 10.

[0026] Working principle: When using the present invention, the user places the expansion tube 9 and the countersunk bolt 10 in the through hole, and then screws the nut 11 to make the countersunk bolt 10 slide upward in the inner cavity of the expansion tube 9, and then expands the bottom end of the expansion tube 9 to achieve a better fixing effect.
