Description
Technical Field
The utility model discloses PC house industrialization technical field especially relates to a top goes out muscle school and transfers auxiliary fixtures.
Background
In the assembly type structure, generally pre-buried vertical steel bar in the prefabricated shear wall (prefabricated post), vertical steel bar stretches out relative prefabricated shear wall (prefabricated post) top face and forms the top and goes out the muscle, and prefabricated shear wall (prefabricated post) bottom is pre-buried to have the sleeve, and the wallboard reinforcing bar of next floor stretches into the connection of the prefabricated shear wall (prefabricated post) of above realization lower floor in the bottom sleeve of this layer of wallboard.
After the lower-layer prefabricated shear wall (prefabricated column) is installed, a floor slab or a beam can be poured on the top surface of the lower-layer prefabricated shear wall, and the extending parts of the sleeve connecting steel bars can generate disturbance in the field concrete pouring process, so that deviation and inclination are caused. After concrete pouring is finished, the positions of the top ribs need to be adjusted before the prefabricated wallboard on the layer is installed, so that the position accuracy of the upper-layer prefabricated shear wall is ensured. However, as the concrete on the floor is hardened, the deviation of the steel bars at some positions is large, and quality problems such as excessive deformation of the steel bars and collapse of the peripheral concrete can be caused in the process of calibration and adjustment.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's is not enough, provides a top play muscle school and transfers auxiliary fixtures, can improve top play muscle school and transfer efficiency, avoids the reinforcing bar excessively to warp, peripheral concrete quality problems such as collapse.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the top rib outlet correction auxiliary tool comprises a sleeve sleeved on a top rib outlet of a shear wall or a cast-in-place column, wherein the sleeve can move up and down relative to the top rib outlet, the bottom end surface of the sleeve is abutted against the top end surface of the shear wall or the cast-in-place column, and the sleeve penetrates through a cast-in-place floor.
Before the floor slab concrete is poured, the sleeve of the tool is sleeved on the top steel bar, and in the floor slab concrete pouring process, the sleeve carries out isolation protection on the steel bar at the top of the shear wall, so that the disturbance of the steel bar at the top in the field concrete pouring process is reduced, the deflection and the gradient of the steel bar at the top are reduced, and the later-stage correction and adjustment efficiency is improved; after the concrete of the floor slab is poured and initially set, the tool is pulled out of the concrete before final setting, and the cavity is formed at the periphery of the top rib, so that the reinforcement adjustment is facilitated, and the efficiency of the adjustment of the top rib is improved; even if the deviation of the steel bars at partial positions is large, the quality problems of peripheral concrete collapse and the like can not be caused in the correcting and adjusting process. The cavity can be filled in the grouting process of the upper prefabricated shear wall sleeve, so that the integrity of the building structure is ensured.
As a further improvement of the above technical solution:
the upper end of the sleeve is provided with a drawing part which is convenient for drawing the sleeve out of the cast-in-place floor concrete.
As a specific structural form of the drawing part, the drawing part includes a mounting plate fixed to an upper end of the sleeve, and a pull ring fixed to the mounting plate.
And the mounting plate is provided with a through hole for the top rib to extend out. Therefore, the sleeve can be abutted against the prefabricated shear wall, and the anti-interference effect is ensured.
In order to avoid the interference of sleeve steel bars on the drawing of the sleeve, the pull ring is arranged on one side of the through hole.
In order to facilitate the extraction of the sleeve and avoid damaging a cast-in-place concrete structure, the sleeve is a taper pipe with a large upper part and a small lower part.
Compared with the prior art, the utility model has the advantages of:
the utility model discloses an auxiliary fixtures, floor concrete placement can go on the isolation protection to the shear force wall top goes out the muscle before to reduce the deflection degree and the gradient that the muscle goes out at the top, improve later stage school and transfer efficiency; the cavity formed after the auxiliary tool is pulled out after pouring is convenient for correcting and adjusting the reinforcing steel bars, so that the later reinforcing steel bar correcting and adjusting efficiency can be greatly improved, and the deformation of the reinforcing steel bars and the damage of the peripheral concrete structure in the correcting and adjusting process are reduced.

Detailed Description
The invention is further described below with reference to specific preferred embodiments, without thereby limiting the scope of protection of the invention.
Example (b):
as shown in fig. 1 to 3, the top rib-out correction auxiliary tool of the embodiment includes a sleeve 1 sleeved on the top rib-out 3, and a drawing part 2 fixed at the upper end of the sleeve 1 for facilitating the drawing of the sleeve 1 from the cast-in-place floor concrete. The internal diameter of sleeve pipe 1 is greater than the diameter that the muscle 3 was gone out at the top to can guarantee that sleeve pipe 1 can go out muscle 3 relatively and reciprocate, and sleeve pipe 1 is big-end-up's taper pipe, makes things convenient for sleeve 1 to extract. In addition, the length of the sleeve 1 is larger than or equal to the thickness of the cast-in-place floor slab 4, and the sleeve penetrates through the cast-in-place floor slab 4 after pouring, so that the sleeve 1 is prevented from being buried by cast-in-place floor slab concrete.
