The invention has the advantages of better preventing the left and right swinging of the building and improving the damping and buffering effect.
Description
Technical Field
The invention relates to the technical field of building earthquake resistance, in particular to a building shock absorption and energy dissipation method based on thread conversion.
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.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a building damping and energy dissipation method based on thread conversion, which can better prevent the left and right swinging of a building and improve the damping and buffering effects; and further enables it to reduce the impact on the functional action of the seismic joint itself.

Wherein, the outer side of the base 14 is further provided with a layer of elastic material layer, and the outer side of the elastic material layer forms the mounting surface.
Like this, elastic material layer's setting can conveniently be connected the limit and insert better fastening behind the slot and fix, and self can produce certain elasticity shock attenuation energy dissipation effect simultaneously. Meanwhile, more separation spaces can be generated by means of elastic deformation of the elastic material layer during quick separation, and quick separation of the device is facilitated. Preferably, the elastic material is a rubber material. Has the advantages of low cost, convenient preparation, excellent elasticity, being beneficial to adjusting the elasticity and the like.
Wherein, the lower extreme position of base 14 is provided with a row of fixed point, and the fixed point is fixed to the building lateral wall through the internal connection of screw 17, and the corresponding downwardly extending of fixed point below is formed with sled piece 18, and base and sled piece 18 are hard material and make.
Like this, when the base and the base of building one side of collapsing do not realize breaking away from, the building of collapsing passes through the base and the base of device drive opposite side and overturns downwards, through the leverage effect of sled piece, can prize the screw more fast reliably, realizes breaking away from. Play the dual fail-safe effect like this, can guarantee under the various condition when one side building collapses, the homoenergetic accomplishes the separation of device and building fast.
Wherein the base 14 at the fixed point location is raised outwardly so that a horizontal distance is provided between the fixed point base and the building side wall.
When one side building collapses downwards like this, can be favorable to more the sled piece to exert leverage effect, can pry the breaking away from of screw realization device better.
