Problems solved by technology

However, the PVC casing pre-buried in the shear wall is not easy to take out. After the hole is sealed, the outer wall often leaks between the PVC casing and the sealing material, which is one of the hidden dangers of the outer wall leakage.
[0003] Therefore, aiming at the disadvantages and deficiencies that the above-mentioned PVC casing pre-buried in the shear wall is not easy to take out, it is very necessary to research and develop a device and a construction method that can smoothly remove the PVC casing from the shear wall

Embodiment 1

[0020] The wall-penetrating PVC casing of the recyclable shear wall tension bolt of the present invention has a novel structure. see now figure 1 , figure 1 It is a schematic structural diagram of a PVC pipe according to an embodiment of the present invention. As shown in the figure, the PVC sleeve is a PVC pipe with a length of 200 mm. The large diameter end 1 of the PVC pipe is 40 mm, and the other small diameter end 3 is 30 mm. Rib 2, the stiffening rib is arranged from one end to the other end of the PVC pipe, and the height of the stiffening rib is 3mm.

Embodiment 2

[0022] figure 2 It is a schematic diagram of the use method of the PVC pipe of the embodiment of the present invention. The usage method of the wall-penetrating PVC casing of the recyclable shear wall anti-tension bolt of the present invention: when the concrete shear wall 4 is poured and the wall-penetrating screw is taken out, only 5 threaded steel bars with a diameter of 12mm and a length of 20mm need to be used. Cooperate with iron hammer 6 and get final product by chiseling out from casing pipe small end 30mm to casing pipe large end 40mm place.

Abstract

The invention relates to a recyclable through-wall PVC (polyvinyl chloride) sleeve for shear wall split bolts. The sleeve is characterized in that the PVC sleeve is a PVC pipe being 200 mm long, diameters of two ends of the PVC pipe are different, the wall thickness of the pipe is 4 mm, and a plurality of stiffening ribs made of the same material are uniformly arranged on the inner wall of the pipe. The recyclable through-wall PVC sleeve for the shear wall split bolts has the advantages that the PVC pipe is novel in structure and convenient to use, hole plugging quality of external wall through screws is improved, the leakage rate is reduced, the through-wall PVC sleeve can be easily taken out and is recyclable, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a casing, in particular to a wall-penetrating PVC casing of a recyclable shear wall tension bolt. Background technique [0002] During the construction of civil construction projects, φ12mm-φ16mm wall-through screws are routinely used for formwork reinforcement. In order to reduce the construction cost and increase the turnover rate of the wall-through screw, a PVC sleeve with a diameter 2mm larger than the wall-through screw is often used to pre-embed in the shear wall. After the formwork is removed, the wall-through screw can be taken out from the pre-embedded PVC casing to achieve the purpose of screw reuse. However, the PVC casing pre-buried in the shear wall is not easy to take out. After the hole is sealed, the external wall leakage often occurs between the PVC casing and the sealing material, which is one of the hidden dangers of external wall leakage. [0003] Therefore, aiming at the disadvantages and deficiencies th...
