Description
Technical Field
The utility model relates to a building tool, in particular to a three-section separated water stop screw.
Background
The water-stopping screw is a bolt for building which can play a role in stopping water. The water stop screw is generally used for a wall body which needs to be waterproof, such as a basement in a building engineering, an underground garage, a civil air defense engineering, a water tank, a sewage treatment plant and the like, which need to be waterproof.
The water stop screw is different from the common wall penetrating screw in that a water stop sheet is welded in the middle of the water stop screw, and after the two screws outside the wall are sawed off by the water stop screw when the template is disassembled, the middle part of the water stop screw is left in the wall, so that the water seepage of the shear wall is ensured. The common wall-penetrating screw rod needs to be integrally taken out and can be repeatedly used, and the water-stopping screw rod and the common wall-penetrating screw rod all play a role in fixing the template.
There is also a three-section water-stopping screw on the market, which is a novel water-stopping screw. Consists of two nuts, an inner rod and two outer rods. The fixed template is not deformed to prevent the die explosion, and meanwhile, the waterproof and moistureproof functions of the wall can be achieved in the second half period of building construction. The other advantage is that after construction, the inner rod is left in the wall, and the outer rods on both sides can be repeatedly used. Therefore, the technical requirement and labor force for cutting the two lead screws in the building construction are reduced, and the three-section water stop screw is widely applied to the building engineering.
However, when the construction of the three sections of water stop screws used at present is finished and the outer rods on two sides are removed, the outer rods on two sides need to be removed one by one; in the process of dismantling the outer rod, as the two ends of the inner rod are respectively connected with the outer rods on the two sides through the two nuts, when the outer rod is rotationally dismantled from the nuts, the inner rod is subjected to a rotation moment due to the existence of a threaded connection friction force, so that the risk of rotation of the inner rod is increased; once the inner rod rotates in a small amplitude, the water stop sheet positioned at the middle position of the inner rod also rotates in a small amplitude, a gap is formed in the wall, and the water seepage risk of the wall is increased.
