Description
Technical Field
The utility model belongs to the technical field of construction of reinforced concrete walls in constructional engineering, and particularly relates to a PVC through-wall water stop bolt pipe.
Background
At present, when concrete of a basement shear wall or a basement shear column is poured in the construction of a reinforced concrete wall body of a building engineering, a water stop bolt rod is needed to fix a template to prevent a formwork from being burst, because the bolt rod penetrates through the wall body, water can easily permeate along a screw rod, a square reinforcing steel bar piece is welded in the middle of the screw rod of the water stop bolt rod to be called a water stop piece, the permeation path of the water can be prolonged, and a certain water stop effect is achieved.
The stagnant water screw rod plays the effect of control concrete placement thickness, and with ordinary wall screw rod difference lies in: 1) a water stop sheet is arranged in the middle of the water stop screw rod; 2) when the formwork is removed, the common wall-penetrating screw rod is integrally pulled out and can be repeatedly used, and the middle section of the water-stopping screw rod is left on the wall body after the two ends of the outer wall of the wall are sawn off so as to ensure the impermeability of the wall body. The traditional water stop screw is of a one-section structure, generally, the whole screw is a full-tooth screw, and a water stop sheet is welded in the middle or an expansion water stop ring is sleeved on the middle of the screw to prevent water from passing through the wall body of the basement.
In order to save steel, a novel water stop screw rod is available in the market, and is changed into a three-section structure from a one-section structure, namely a three-section type counter-pulling water stop screw rod. The three-section type counter-pulling water-stopping screw rod is formed by connecting two symmetrical end screw rods through a middle screw rod, the middle screw rod is provided with a water-stopping sheet and two locking parts, and the end screw rods are provided with fastening threads and are provided with fastening nuts. And connecting external threads are arranged at two ends of the middle screw rod, and a connecting internal thread is arranged at one end of the end screw rod and matched with the connecting external threads of the middle screw rod. The joint of the middle screw rod and the end screw rod is sleeved with a tubular cushion block, the center part of the cushion block is a guard ring, one end face of the tubular cushion block is circumferentially provided with a circle of axial upright columns, and gaps are reserved among the upright columns. The end face of the cushion block is provided with a material saving hole. The water stop screw rod formed by sectionally combining the middle screw rod and the end screw rod is used for building a concrete pouring mold like a common water stop screw rod, the existing construction process is not required to be changed, and the water stop screw rod is easy to popularize and apply. After concrete is poured and the template is removed, the end screw can be taken down from the middle screw buried in the wall body for recycling, the recycled end screw is matched with a new middle screw and can be reused, and the concrete pouring device has the defects of complex structure and high screw fouling rejection rate.

The diameter of the straight pipe body is 20-26 mm, and the wall thickness is 0.8-1.5 mm.
The ratio of the maximum diameter of the corrugated pipe section to the diameter of the straight pipe body is 3: 1.
The corrugated pipe section is in a sawtooth shape or a triangular shape.
The periphery of the corrugated pipe section is provided with annular fin ridges, and the height of the annular fin ridges is 6-15 mm.
The corrugated pipe section is arranged on the outer wall side when being installed.
And holes at two ends of the PVC wall-penetrating water stop bolt pipe are plugged by rubber plugs after the template is dismantled.
Compared with the prior art, the utility model has the beneficial effects that: 1) the wall-penetrating bolt rod is made of PVC plastic materials, is low in cost and easy to obtain, and can be reused by replacing a conventional water-stopping bolt with the prefabricated PVC water-stopping sleeve, so that the consumption of steel is saved, and the construction cost is reduced. 2) The ripple part plays the same role as a water stop steel sheet of a normal water stop bolt, prevents water flow from migrating along the wall body by increasing the difficulty of a gap between the water penetration pipe and concrete, and is plugged by a compact, impervious and micro-expanded material which can be combined with a PVC wall penetration water stop bolt pipe after the concrete is cast and removed, so that the water resistance is ensured.
