Building protection device based on anti-seismic joint

Abstract

The invention discloses a building protection device based on an anti-seismic joint. The building protection device comprises two bases mounted on the two-side building side walls of the adjacent sides of two adjacent buildings, and further comprises a sleeve with internal threads and a screw rod with external threads; the sleeve and the screw rod are horizontally arranged and each provided with amatching end for mutual matching and a mounting end connected with the bases, the matching end of the screw rod is inserted into the matching end of the sleeve by a certain distance and is in threaded fit with the matching end of the sleeve, and the mounting end of the sleeve or the screw rod is rotatably connected with the bases; and the inclination angle of threaded inclined faces of the external threads and the internal threads is larger than a friction angle. The building protection device has the advantages that the buildings can be better prevented from swinging leftwards and rightwards, and the damping and buffering effects are improved.

Description

technical field [0001] The invention relates to the field of building anti-seismic technology, in particular to a building protection device based on anti-seismic joints. Background technique [0002] Anti-seismic joints, also known as anti-seismic joints, refer to the structural joints designed between adjacent building units during the design and construction of houses, which are pre-set to reduce or prevent the collision of adjacent building structural units caused by earthquakes. gap. In order to prevent the building from being damaged by the earthquake, the building is divided into several independent parts with simple shape and uniform structural rigidity by using anti-seismic joints. [0003] However, after the seismic joint separates the building into individual building units, the horizontal area of ​​each building unit is small, its own stability is poor, and the anti-swing effect is reduced. The upper end of the building will generate a large swing vibration, wh...

Problems solved by technology

[0005] But these existing patents also have the following defects: 1. in the device, all rely on the spring members fixedly arranged along the horizontal direction to realize shock absorption and buffering. Compression and elongation, the spring itself will also directly produce a rebounding reverse force in the horizontal direction after being compressed and stretched

Therefore, the active force and reaction force of the spring are converted back and forth in the horizontal direction, which makes the actual shock absorption effect of the device and the effect of reducing the left and right swing of the building poor.

2 The function of the anti-seismic joint itself is to avoid the impact on adjacent building units when a single building unit collapses and falls, and the structure of the existing anti-seismic joint shock-absorbing devices is fixedly installed between adjacent buildings, so when a single building unit When it collapses and falls, it will act on the adjacent building units through the traction of the shock absorbing device, which greatly reduces the function and significance of the seismic joint itself
