Abstract

The utility model discloses a novel double-steel-plate concrete composite shear wall. The novel double-steel-plate concrete composite shear wall comprises a reinforced concrete shear wall body and steel-reinforced concrete columns which are connected to the two ends in the length direction of the reinforced concrete shear wall body. Two steel plates which are vertically placed and stretch in the length direction of the shear wall body in a parallel separation mode are embedded into the reinforced concrete shear wall body. The opposite sides of the two steel plates are the inner portion, and the back-to-back sides of the two steel plates are the outer portion, toggle pins or connecting keys are welded to the inner sides and the outer sides of the two steel plates respectively, and the two ends of the two steel plates are connected with section steel in the steel-reinforced concrete columns respectively. According to the composite shear wall, the mechanical property of the steel plates and the mechanical property of concrete can be brought into full play, better bearing capacity, ductility and energy dissipation capacity are acquired under the effect of strong shock, and the novel double-steel-plate concrete composite shear wall is suitable for high-rise and super high-rise buildings.

Description

A kind of novel double steel plate combined concrete shear wall
Technical field
The utility model relates to building aseismicity technical field, is specifically related to a kind of comprehensive strength high, the novel double steel plate combined concrete shear wall that anti-seismic performance is superior.
Background technology
Shear wall is the of paramount importance lateral resisting structure member of high level and Super High, develops the good shear wall system of anti-seismic performance very important.Steel-concrete compound shear wall has made full use of and has brought into play steel and Reinforced Concrete Materials advantage separately, maximizes favourable factors and minimizes unfavourable ones, and is a kind of low cost, high efficiency textural association form, in China, is also a kind of tool new structure system with broad prospects for development.
Existing steel plate concrete combined shear wall mainly comprises embedded steel plate-concrete combined shear wall and the large class of outsourcing double steel plate-combined concrete shear wall two.This two large class shear wall comprises three kinds of structural forms below: embedded steel plate-concrete combined shear wall, one-sided steel plate-concrete combined shear wall and double steel plate-combined concrete shear wall.The more common shear wall of above-mentioned two class compound shear wall all has a more substantial increase in anti-seismic performance, is the structural system being worthy to be popularized, but also has shortcoming and defect part separately.As embedded individual layer steel plate concrete combined shear wall exists the large deformation in the situation that, may there is cracking and peel off in concrete slab, the effect of contraction of steel plate is weakened greatly, makes the shortcomings such as the ductility energy dissipation capacity of shear wall under large shake effect significantly reduces.There is following shortcoming in outsourcing double steel plate-combined concrete shear wall: after (1) large deformation, steel plate is outwards bent drum, inner concrete constraint is reduced, thereby causes later stage depression of bearing force too fast; (2) encased steel plate is outside exposed, has the shortcomings such as fire prevention difference and durability are low.Given this, this case inventor further investigate the problems referred to above, then has this case to produce.
Utility model content
The purpose of this utility model is to provide a kind of anti-seismic performance good, the novel double steel plate combined concrete shear wall of fire prevention and good endurance.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of novel double steel plate combined concrete shear wall, comprise reinforced concrete shear wall main body and be connected in the profile steel concrete column at reinforced concrete shear wall principal length direction two ends, described reinforced concrete shear wall main body is embedded with two and vertically places and along the parallel steel plate from extending of shear wall principal length direction; Take the relative side of described two block plates as in, outside a side is in opposite directions, the inside and outside both sides of described two block plates are welded with respectively peg or connecting key, the both ends of described two block plates respectively with above-mentioned profile steel concrete column in shaped steel link together.
Between the inner side of above-mentioned two block plates, be provided with steel tie or drawknot batten plate.
Adopt after technique scheme, double steel plate combined concrete shear wall of the present utility model, form the embedded double steel plate combining structure of band newel post, compared with prior art, it at least has following beneficial effect, and two-layered steel plates is embedded in the constraint that is subject to steel concrete in steel concrete, suppresses two-way flexing, two steel plates retrain the steel concrete between the two simultaneously, have improved intensity and the deformation performance of core steel concrete; And concrete plays a protective role to steel plate outside steel plate, take into account fire prevention and anticorrosive effect.Weld stud on steel plate, strengthens the coupling between concrete and steel plate, Transfer of Shear and coordinate steel plate and steel concrete between extruding bending deformation, prevent from occurring between steel plate and steel concrete two-way separation problem.The existence of profile steel concrete column, can bear more axle power, effectively reduces shear wall ratio of axial compressive force to axial compressive ultimate capacity of section, and in the severe earthquake action later stage, after shear wall hydraulic performance decline, profile steel concrete column can effectively avoid body of wall to collapse as second anti-vibration defense lines.By connection measure, profile steel concrete column and shear wall form entirety and come shared shearing and moment of flexure, and compound shear wall can obtain better bearing capacity and deformation performance.In sum, steel plate concrete combined shear wall of the present utility model, its bearing capacity is high, and ductility and energy dissipation capacity are good, and have the advantages such as fire line, good endurance, and cost performance is high, has actual promotional value.
