Reinforcing bar model used in the shear wall of different load-bearing standards is different, currently, for using the above steel of diameter 12mm
The shear wall of muscle, vertical connection type is mainly reinforced bar sleeve grouting connection during installation, and specific practice is upper wall
Steel pipe sleeve is arranged in the lower part of body, and there are external screw threads for the lower end of upper wall steel bar, and there are internal screw thread, upper walls for the upper end of steel pipe sleeve
The external screw thread of body reinforcing bar is installed on the internal screw thread of steel pipe sleeve, and the lower intracorporal reinforcing bar of wall passes through the steel pipe that floor is inserted into upper wall
In sleeve, then penetration concrete grouting material is solidified and is fixed.But for using cutting for diameter 8mm and 10mm reinforcing bar
Power wall, if also using above-mentioned thread connecting mode between the reinforcing bar and steel pipe sleeve of upper wall, the wall thickness of steel pipe sleeve by
In want pre-threaded and consider threaded connection dynamics and substantially cannot be thinning, for thinner steel pipe casing, there is no very at present
The connectivity problem between reinforcing bar and steel pipe sleeve is solved well.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of connection structure of the wall up and down of precast shear wall,
The structure is directed to the steel that the reinforcing bar of diameter 8mm and 10mm can use the side wall of the steel pipe sleeve of relatively previous 12mm reinforcing bar thinner
Pipe sleeve cylinder, and be connected firmly, rapid and convenient of constructing is effectively saved steel, convenient for promoting the use of.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that:
A kind of connection structure of the wall up and down of precast shear wall, including upper wall, lower wall and be located at upper wall under
Floor between wall, which is characterized in that be equipped with the upper wall steel of several diameter 7.5mm ~ 10.5mm in the upper wall side by side
Muscle is equipped with thin-wall steel tube in upper wall lower part, and upper wall steel bar lower end is through in thin-wall steel tube, is equipped with side by side in the lower wall
The lower wall steel bar of several diameter 7.5mm ~ 10.5mm, lower wall steel bar is upward through the floor and correspondence penetrates thin-wall steel tube
It is interior, nut cap is equipped between thin-wall steel tube and upper wall steel bar, there are gas vent in nut cap, the gas vent leads to wall
Outside, on thin-wall steel tube there are injected hole, concrete grouting material is marked with by upper wall steel bar and lower wall steel bar in thin-wall steel tube
Fixed, the wall thickness of the thin-wall steel tube is 2 ~ 2.5mm, and the outer diameter of thin-wall steel tube is 22 ~ 32mm.
Preferably, the injected hole is located on the side wall of the thin-wall steel tube, and apart from the upper wall bottom surface 2.5 ~
3.5cm。
Preferably, plastic tube is equipped on the gas vent in the nut cap, the plastic tube passes through the side wall of the upper wall
And open end is stayed in outside upper wall.
Preferably, the floor is made of bottom pulp layer and superimposed sheet layer, and the superimposed sheet layer is located at the lower section of bottom pulp layer.
The utility model has the beneficial effects that changing with the thread connecting mode of up wall steel bar and steel pipe casing as grouting
It is fixed, nut cap is set between upper wall steel bar and thin-wall steel tube, grouting can be made more substantial, the gas vent stayed in nut cap can be with
Upper gas is discharged, makes concrete grouting material full of entire thin-wall steel tube, enhances the fastness of connection.The utility model sampling
Thin-wall steel tube wall thickness be 2 ~ 2.5mm, relatively previous thickness of steel pipe is thinning, save steel, but connection type secured and
Load bearing effect fully meets the building requirements of 8mm and 10mm shear wall.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
With reference to the accompanying drawing, the utility model is described further:
As shown in Figure 1, the present apparatus includes upper wall 1, lower wall 2 and the floor 3 between upper and lower wall, floor 3 can
To be made of superimposed sheet layer 4 and bottom pulp layer 5, bottom pulp layer 5 is located at the upper surface of superimposed sheet layer.The inner lower of upper wall 1 is embedded with
Multiple thin-wall steel tubes 6 arranged side by side, more upper wall steel bars 7 are inserted into corresponding thin-wall steel tube 6 from the top of upper wall 1
And lower end a part stays in inside thin-wall steel tube 6, then installs nut cap 11 additional between upper wall steel bar and thin-wall steel tube, nut cap can
Slurry is gone to inside upper wall when preventing from being in the milk in thin-wall steel tube, likewise, lower wall steel bar 8 sequentially passes through building from bottom to top
