Abstract
The invention provides a novel coupled shear wall structure which comprises coupling wall columns and a connecting beam thereof. The connecting beam comprises end beams at two ends of the connecting beam and a middle beam which is positioned in the middle of the connecting beam and is lower in strength, and the middle beam is detachably connected with the two end beams. According to the technical scheme, the connecting beam of the novel coupled shear wall structure is provided with the detachable middle beam which is lower in strength as compared with other portions of the connecting beam, and the middle beam is strong enough so as to be a component of a wall under normal conditions; during earthquake, the middle beam is stressed in a concentrated manner, deforms moderately and absorbs most of earthquake energy; and during strong earthquake, the middle beam severely deforms until the middle beam is damaged, so that a main portion of the shear wall is protected, the middle beam can be detached after being damaged, and a middle beam in a good condition can be mounted on the shear wall. Compared with the prior art, the novel coupled shear wall structure has excellent seismic resistance and concentrated shock absorption properties, and the integral shear wall can be effectively protected. Besides, the middle beam is easy to replace, repair difficulty after earthquake is reduced, repair cycle is shortened, and the novel coupled shear wall structure is convenient and practical.
Description
Technical field
The present invention relates to the earthquake-resistant building technical field, be specifically related to a kind of have good antidetonation and concentrated shock absorbing performance, can reduce the shake back and repair difficulty, shorten the novel limb shear wall structure of repairing efficiency.
Background technology
In order to improve the performances such as antidetonation in houses such as building, the house adopts mostly and joins the limb shear wall structure, and existing limb shear wall structure roughly comprises company's beam of wall limb and wall limb.
The wall limb has constituted the rigid bodies of house wall; Lian Liang is as the main member of the absorption of the transmission of being connected between wall limb and the wall limb, power and power; Play protection wall limb; Keep the effect of building structure, the existing beam that connects adopts Reinforced Concrete Materials to process mostly, proposes the steel plate concrete shear wall that a kind of anchored end is provided with peg like Chinese utility model patent CN201120315432.3 and connects beam; By the vertical muscle of Lian Liang, connect beam stirrup, connect the beam coagulation, steel plate, peg form, it is building or the structure that steel plate concrete shear wall that anchored end is provided with peg connects beam that the steel plate concrete shear wall that said anchored end is provided with peg connects beam.This utility model is utilized higher shear strength of steel plate and good plastic property, resists external force jointly with steel concrete, can prevent that Lian Liang from brittle shear taking place destroy, and improves to connect the ductility energy dissipation capacity of beam under geological process.But this utility model is pretended the time spent and can be produced probabilistic deformation such as part or integral body receiving earthquake etc.;, self also can involve the wall limb that it connects when being damaged; And then can not play effective protective effect to the wall limb; And the syndeton globality of itself and wall limb is stronger, and the repair difficulty after the shake is big, and repairing efficiency is long.
In order to address the above problem; China utility model patent CN201020644760.3 proposes a kind of low-yield steel and connects the beam shear wall structure; Comprise the reinforced concrete wall limb; The dark stake of concrete filled steel tube vertically is set in reinforced concrete wall limb inside, and at least one segment girder steel is uniformly-spaced welded in the dark stake of said concrete filled steel tube, is connected with the low-yield girder steel between the first-class high segment girder steel of adjacent reinforced concrete wall limb.Under severe earthquake action, the unique low-yield girder steel that is provided with of this utility model can produce bigger deformation absorbing most of seismic energy, and its stress and deformation point is concentrated; Can not involve the wall limb that is connected, when macroseism, low-yield is fiery and forthright at first to be damaged; To avoid the wall limb to receive the effect of strong shearing force; The wall limb is played a very good protection, and difficulty is big but this utility model still can not solve shake back repair, defectives such as repairing efficiency length.
Given this, this case the inventor further investigate the problems referred to above, has this case to produce then.
Summary of the invention
The object of the present invention is to provide a kind of novel limb shear wall structure, have good antidetonation and concentrated shock absorbing performance, shear wall integral body is had effective protective effect, and can effectively reduce the shake back and repair difficulty, shorten repairing efficiency.
In order to achieve the above object, the present invention adopts such technical scheme:
A kind of novel limb shear wall structure comprises wall limb and Qi Lian beam; The said beam that connects comprises the end carriage that is in two ends and is in middle part and the more weak stage casing beam of intensity, said stage casing beam and two said end carriage is dismantled and assembled links together.
The partial fixing of above-mentioned end carriage is embedded in the above-mentioned wall limb.
Above-mentioned end carriage is provided with shearing bolt in the inner part of above-mentioned wall limb.
Above-mentioned end carriage is exposed to the outer part of above-mentioned wall limb and is connected through bolt with above-mentioned stage casing beam.
Above-mentioned end carriage and above-mentioned stage casing beam have the junction plate that is parallel to each other, and above-mentioned bolt passes two said junction plate lockings.
Above-mentioned junction plate is parallel to the above-mentioned cross section that connects beam.
Above-mentioned company beam is a steel structure frame, and is provided with the tabular stiffening rib that is parallel to company's beam section in the framework.
The corresponding above-mentioned beam that connects in the side of above-mentioned wall limb is provided with the broken panel of cracking resistance.
The broken panel of above-mentioned cracking resistance is embedded in the side of above-mentioned wall limb.
Above-mentioned wall limb is the reinforced concrete wall limb.
After adopting technique scheme, novel limb shear wall structure of the present invention, Qi Lianliang has dismantled and assembled and intensity connects the weak stage casing beam of its part of Liangqi; The stage casing beam has certain intensity, and under normal circumstances it has constituted the ingredient of house wall, when earthquake takes place; The stage casing beam factor such as concentrates stressed owing to intensity is more weak with structure; And produce bigger distortion, can absorb most of seismic energy, during macroseism; The stage casing beam produces drastic deformation until damage, protects the main part (comprising Lian Liang other part except that the beam of stage casing) of shear wall structure with this.After the stage casing beam damages, can it be pulled down, intact stage casing beam is installed in replacement, just can realize repairing after the shake in house.
Compared with prior art, novel limb shear wall structure of the present invention has good antidetonation and concentrated shock absorbing performance, when the earthquake that is lower than fortification intensity; Especially main body is unaffected to join limb shear wall structure integral body, needn't damage reparation, when being higher than the earthquake of fortification intensity; The stage casing beam at first damages, and prevents that with this agent structure that joins the limb shear wall structure from receiving shearing action, protects it; The main body damage of avoiding effectively joining the limb shear wall structure causes house collapse; And then cause the loss of life and property etc., and the stage casing beam has dismantled and assembled replacement function, reduced the difficulty of shake back repair; Shortened repairing efficiency, convenient and practical.
