Description

A kind of precast reinforced concrete shear wall
Technical field
The utility model relates to a kind of precast reinforced concrete shear wall.
Background technology
The connection of existing precast reinforced concrete shear wall is vertical distribution bar and adopts slurry anchor sleeve connection, and adds shear reinforcement.This kind of connection can accomplish reliable power transmission to the shear wall of total cross-section pressurized, even but shear wall total cross-section tension cracking time just can not be reliably stressed, bring very large potential safety hazard.Along with country is to the raising of earthquake fortification level, when coming earthquake, the shear wall of total cross-section tension is more and more common, to need when total cross-section tension also the shear wall of reliable power transmission to connect.
Utility model content
The utility model object is: for above-mentioned technical problem, provides a kind of structural stability and the high precast reinforced concrete shear wall of safety.
The technical solution of the utility model is: a kind of precast reinforced concrete shear wall, comprise upper strata body of wall, lower floor's body of wall and by the linkage of described upper strata body of wall together with lower floor wall connecting, described linkage comprises vertical layout and the shearing resistance pin key be made up of shaped steel, weld together with described shearing resistance pin key and the same dowel vertically arranged, and the grout sleeve be vertically fixed in the body of wall of described upper strata, the first half of described shearing resistance pin key and the first half of described grout sleeve are anchored in the body of wall of described upper strata, and the upper end of dowel is fixed in grout sleeve, the latter half of described shearing resistance pin key and the latter half of described grout sleeve are anchored in described lower floor body of wall.
The utility model, on the basis of technique scheme, also comprises following preferred version:
For making the cross section of the shaped steel of described shearing resistance pin key in " ten " font, described dowel is welded on the middle part of this " ten " font shaped steel, and the length of dowel is longer than shear-pin key length.
Beam is watered after being provided with level between described upper strata body of wall and lower floor's body of wall.
Also can be other shapes for making the cross section of the shaped steel of described shearing resistance pin key 3, as " work " font.
The utility model has the advantages that: the shearing resistance pin key that the linkage of this precast reinforced concrete shear wall of the utility model is made with shaped steel, the two ends up and down of shearing resistance pin key are anchored in upper strata body of wall and lower floor's body of wall respectively, after the concrete cracking at levels wall connecting place exits shearing resistance work, shear-carrying capacity is provided by shearing resistance pin key, shearing resistance pin key still can be reliably stressed, ensure that structural stability and the safety of shear wall.And do not lose efficacy under ultimate limit state can being ensured with the dowel that shearing resistance pin key is welded and fixed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the facade view of this precast reinforced concrete shear wall of the utility model embodiment;
Fig. 2 is the top plan view of this precast reinforced concrete shear wall of the utility model embodiment;
Wherein: 1-upper strata body of wall, 2-lower floor body of wall, 3-shearing resistance pin key, 4-dowel, 5-grout sleeve, waters beam after 6-level.
Detailed description of the invention
Fig. 1 and Fig. 2 shows a specific embodiment of this precast reinforced concrete shear wall of the utility model, identical with traditional precast reinforced concrete shear wall is, it also comprises upper strata body of wall 1, lower floor's body of wall 2 and by the linkage of upper strata body of wall together with lower floor wall connecting, waters beam 6 after being provided with level between described upper strata body of wall 1 and lower floor's body of wall 2.
The key improvements of the present embodiment is that the form of structure of described linkage is different from traditional structure, in this example, described linkage comprises vertical arranged and the shearing resistance pin key 3 be made up of shaped steel, to weld together and the same vertical dowel 4 arranged and the grout sleeve 5 be vertically fixed in described upper strata body of wall 1 with described shearing resistance pin key 3.The first half of described shearing resistance pin key 3 and the first half of described grout sleeve 5 are anchored in described upper strata body of wall 1, and the upper end of dowel 4 is fixed in grout sleeve 5, the latter half of described shearing resistance pin key 3 and the latter half of described grout sleeve 5 are anchored in described lower floor body of wall 2.
With reference to shown in Fig. 2, in this example, for making the shaped steel of described shearing resistance pin key 3, its cross section is in " ten " font, and described dowel 4 is welded on the middle part of this " ten " font shaped steel, and the length of dowel is longer than shear-pin key length.
Certainly, also can be other shapes for making the cross section of the shaped steel of described shearing resistance pin key 3, such as " work " font.
The linkage of this precast reinforced concrete shear wall of the present embodiment have employed the shearing resistance pin key 3 that shaped steel is made, the two ends up and down of shearing resistance pin key 3 are anchored in upper strata body of wall and lower floor's body of wall respectively, after the part concrete cracking at levels wall connecting place exits shearing resistance work, shear-carrying capacity is provided by shearing resistance pin key, shearing resistance pin key still can be reliably stressed, ensure that structural stability and the safety of shear wall.The dowel be welded and fixed with shearing resistance pin key did not lose efficacy under can ensureing ultimate limit state.
Refer again to shown in Fig. 1, now the manufacturing process of this for the present embodiment precast reinforced concrete shear wall be simply described below:
First at factory's prefabricated described upper strata body of wall 1 and lower floor's body of wall 2 respectively.And when making lower floor's body of wall 1, the latter half of the latter half of shearing resistance pin key 3 and described dowel 4 being anchored in lower floor's body of wall 2, and the first half of shearing resistance pin key 3 and dowel 4 is stretched out outside lower floor's body of wall 2.Make upper strata body of wall 1 time, reserve vertical blind hole in the bottom of upper strata body of wall 1, and in this blind hole pre-buried grout sleeve 5.During practical application, upper strata body of wall 1 and lower floor's body of wall 2 are transported to erecting bed, after lower floor's body of wall 2 installs, beam 6 is watered after level is built on lower floor's body of wall 2 top, afterwards upper strata body of wall 2 is arranged in the top of lower floor's body of wall 2, and make the first half of shearing resistance pin key 3 and dowel 4 stretch into (upper end of dowel 4 is inserted in grout sleeve 5) in the reserved vertical blind hole in upper strata body of wall 1 bottom, pour special grouting material in the most backward vertical blind hole, the first half of shearing resistance pin key 3 and dowel 4 is anchored in upper strata body of wall 1.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
