Anti-seismic device for buildings

Abstract

The invention discloses an anti-seismic device for buildings. The anti-seismic device comprises a base and a connecting top plate between which a seismic reduction structure and a floating slab are arranged, wherein the seismic reduction structure comprises a cylinder body, an oil cylinder, a propping top plate, a spring, a wane and a rotating shaft; the bottom end of the cylinder body is fixed in the middle of the base; the bottom end of the oil cylinder is welded and fixed on the bottom wall of the cylinder body, and the height of the oil cylinder is smaller than that of the cylinder body; a piston shaft of the oil cylinder is fixed in the center of the bottom surface of the propping top plate; the spring is positioned between the propping top plate and the top wall of the cylinder body; an insert cavity is formed in the middle of the floating slab; and the middle of the wane is connected to the top wall of the cylinder body through the rotating shaft, the outer side end of the wane extends into the insert cavity, and the inner side end of the wane is positioned in the cylinder body and positioned under the propping top plate. The anti-seismic device for the buildings is reasonable in structural arrangement, and can effectively play an anti-seismic role, the use stability and the use reliability are improved, the technical problem of poor anti-seismic stability in a traditional technology is solved, the applicability is strong, and the practicability is high.

Description

Technical field [0001] The invention belongs to the technical field of construction equipment, and in particular relates to an anti-seismic device for construction. Background technique [0002] In building projects such as buildings and bridges, earthquake-resistant structures are generally installed to reduce disasters caused by earthquakes. Traditionally, the seismic structure of buildings is mainly composed of shock-absorbing seats, shock-absorbing springs and connecting roofs, which can be effective to a certain extent. However, its use stability is relatively limited. At the same time, due to its weak pull-out resistance and high cost of its overall structure, it will seriously affect its scope of application and limit its practicality. Summary of the invention [0003] The purpose of the present invention is to provide an anti-seismic device for buildings with reasonable structure and good stability in use, and aims to solve the technical shortcomings of poor anti-seismic s...
