Description
The application is a divisional application of patent application No. 202010697262.3, invention patent 'a building protection device based on earthquake-proof joint' filed on filing 2020-07-20.
Technical Field
The invention relates to the technical field of building earthquake resistance, in particular to a building protection device based on earthquake-resistant joints.
Background
An earthquake-proof joint, also known as a quakeproof joint, is a structural joint designed between adjacent building units when a building is designed and built, and is a gap preset to reduce or prevent collision of the adjacent building structural units caused by earthquake action. In order to prevent the house from being damaged by earthquake, the house building is divided into a plurality of independent parts with simple shapes and uniform structural rigidity by using the shockproof joints.
However, after the earthquake-resistant joint divides the building into single building units, the horizontal area of each single building unit is small, the stability of each single building unit is poor, the swing-resistant effect is reduced, and especially for some high-rise buildings, the upper end of each single building unit can generate large swing vibration in some microminiature earthquakes and windy weather, so that the normal use of the building is greatly influenced. Meanwhile, when the building units are high in height, the single building unit is too large in swing amplitude, and collision between the adjacent building units is easily caused to cause damage.
To solve this problem, there are some prior art patents for shock absorbing devices to be installed between the anti-seismic seams. For example, CN201920488207.6 discloses a shockproof joint anti-collision device for building construction; CN201920880239.0 discloses an anti-collision device for quakeproof joints of building construction; CN201721077895.4 discloses a composite building anti-vibration joint device. The devices of these patented technologies can be installed between adjacent shock absorbing and shock resistant seams and are used to reduce the impact of an earthquake or hurricane on the swinging of the upper end of the building.
However, these prior patents also have the following drawbacks: all rely on the spring member who fixedly sets up about the horizontal direction to realize shock attenuation and buffering among 1 device, during the device was used, the spring is compressed and extension repeatedly at pressure and pulling force on the horizontal direction, its self also repeatedly, and the spring also can directly produce the reverse effort of bounce-back on the horizontal direction after atress compression and tensile self. Therefore, the acting force and the reacting force of the spring are converted back and forth in the horizontal direction, so that the actual damping effect of the device is poor, and the effect of reducing the left and right swinging of the building is poor. 2 the function effect of antidetonation seam self is the influence to adjacent building unit when avoiding single building unit to collapse and fall, and current antidetonation seam damping device's structure is fixed mounting between adjacent building, so when single building unit collapses and falls, can draw the effect through damping device and act on adjacent building unit, so greatly reduced the function effect and the meaning of antidetonation seam self.
