Description
Technical field
The present invention relates to technical field of buildings more particularly to a kind of connecting structure of the vertical piece of overlapped shear wall.
Background technique
Overlapped shear wall structure has and installs good excellent of light, overall performance as a kind of assembled arthitecutral structure system
Point, has a extensive future.There are vertical pieces between adjacent two overlapped shear walls prefabricated components, after concrete is arranged in vertical piece
Pour section.The connecting structure of the vertical piece of overlapped shear wall is that the adjacent overlapped shear wall prefabricated components of two panels and centre are vertical mixed
A kind of horizontal connection construction measure of the integral overlapped shear wall of section horizontal connection is poured after solidifying soil.
In traditional overlapped shear wall prefabricated components, the connecting structure of the vertical piece of overlapped shear wall mainly uses cavity
Layer separately sets the form of bar splicing, and horizontal reinforcement is not overhanging in overlapped shear wall.Using the overlapped shear wall of this kind of interconnection technique,
Although the production of component is more convenient, connecting structure has certain deficiency, comprising: (1) the inside and outside leaf of overlapped shear wall is prefabricated
There are vertical straight joint, horizontal connection reinforcing bar " interior receipts ", connection function and structural integrities at left and right sides of vertical piece for overlapping layers
There is certain weakening；(2) it is not easy to control separately to set the positioning binding of reinforcing bar scene, can not effectively guarantee that vertical piece connects reliable
Property.
Summary of the invention
In view of the above-mentioned problems, now providing the connection structure of a kind of reasonable stress and the reliable vertical piece of overlapped shear wall of connection
It makes.
Specific technical solution is as follows:
A kind of connecting structure of the vertical piece of overlapped shear wall, has the feature that, in the perpendicular of adjacent overlapped shear wall
Horizontal hoop is set along wall high direction into piece, the horizontal reinforcement in leaf overlapping layers inside and outside in overlapped shear wall is extended to
It bends and turns round again after certain length in vertical piece and form semi open model ring-type water in the cavity layer for extend to overlapped shear wall
Flat reinforcing bar, the horizontal hoop in vertical piece is taken to be placed on semi open model circular horizontal reinforcing bar and bind forms multiple closeds
Cuff is inserted into vertical applied force reinforcing bar, the casting concrete into overlapped shear wall cavity layer and vertical piece in closed cuff
Horizontal hoop, semi open model annular horizontal reinforcing bar and vertical applied force Bar Anchorage and connect adjacent overlapped shear wall to be formed
It is whole.
The connecting structure of the vertical piece of above-mentioned overlapped shear wall, also has the feature that, inside and outside in overlapped shear wall
Horizontal reinforcement in leaf overlapping layers, which extends in vertical piece, to be bent 90 degree again and extends to apart from central axes after certain length
Formation semi open model circular horizontal steel in the cavity layer for turning 90 degrees and running parallel to overlapped shear wall is returned after 15mm-25mm again
Muscle.
The connecting structure of the vertical piece of above-mentioned overlapped shear wall, also has the feature that, turns round in overlapped shear wall
The horizontal reinforcement anchorage length in the cavity layer of overlapped shear wall is extended to not less than 1.2laE。
The connecting structure of the vertical piece of above-mentioned overlapped shear wall, also has the feature that, semi-open in vertical piece
Formula circular horizontal reinforcing bar mutually disjoints and is not in contact with each other.
The beneficial effect of above scheme is:
1) by being inserted into vertical applied force reinforcing bar in closed cuff, so that pouring concrete and two sides are folded after in vertical piece
Combination shearing wall realization is reliably connected, and improves the compatible deformation ability of the two, ensure that the whole stress of the two；
2) horizontal reinforcement revolution is anchored in overlapped shear wall cavity layer, so that horizontal reinforcement power transmission is reasonable, can effectively be mentioned
The shear-carrying capacity of high vertical piece, prevents local shear failure；
3) the overlapped shear wall component with semi open model circular horizontal reinforcing bar can carry out pre-manufactured, and manufacture conveniently,
And the presence of semi open model circular horizontal reinforcing bar does not influence the transport and stacking of overlapped shear wall component.
Detailed description of the invention
Fig. 1 is the cross-section structure signal of the connecting structure of the vertical piece of overlapped shear wall provided in the embodiment of the present invention
Figure；
Fig. 2 is that the steel bar arrangement in the connecting structure of the vertical piece of overlapped shear wall provided in the embodiment of the present invention is shown
It is intended to.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art without making creative work it is obtained it is all its
His embodiment, shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be further explained below with reference to the attached drawings and specific examples, but not as the limitation of the invention.
As shown in Figure 1 and Figure 2, in the connecting structure of the vertical piece of the overlapped shear wall provided in the embodiment of the present invention,
Horizontal hoop 2 is set along wall high direction in the vertical piece 6 of adjacent overlapped shear wall 1, leaf inside and outside in overlapped shear wall 1 is folded
Horizontal reinforcement 3 in conjunction layer, which extends to, to be bent 90 degree after certain length in vertical piece 6 again and extends to apart from central axes 15mm-
Formation semi open model circular horizontal reinforcing bar in the cavity layer 7 for turn 90 degrees and run parallel to overlapped shear wall 1 is returned after 25mm again, it will
Horizontal hoop 2 in vertical piece 6, which is taken, to be placed on semi open model circular horizontal reinforcing bar and binds to form 4 closed cuffs 4,
It is inserted into vertical applied force reinforcing bar 5 in closed cuff 4, finally casting concrete and is bound round level into cavity layer 7 and vertical piece 6
Adjacent overlapped shear wall 1 is simultaneously connected formation entirety by muscle 2, semi open model circular horizontal reinforcing bar and the anchoring of vertical applied force reinforcing bar 5.
Overlapped shear wall 1 can be carried out to pre-bend in the present invention and obtain the overlapping with semi open model circular horizontal reinforcing bar
Shear wall 1, the presence of semi open model circular horizontal reinforcing bar neither influences the transport and stacking of overlapped shear wall 1, and pre-bend is raw
Production mode to assemble convenient and quick construction.
