Description

TECHNICAL FIELD

[0001] The utility model relates to a pool anti-seepage construction technology field, concretely relates to a net format water stop bolt system. BACKGROUND

[0002] In the pool wall construction process, the water stop bolt is often used to reinforce the formwork. The traditional water stop bolt adopts a single group installation mode, that is, each group of water stop bolts is independent of each other. A group of water stop bolts locally reinforces the two side formworks, and multiple groups of water stop bolts jointly reinforce the two side formworks. Concrete is poured in the two side formworks to form the pool wall. In order to prevent seepage, a water stop piece is arranged on the water stop bolt.

[0003] However, this structure has the following disadvantages: 1. poor integrity, which is prone to deviation, misplacement, etc. under the impact of steel bar installation, formwork installation and concrete pouring; 2. installation quality control is difficult due to the influence of the technical differences of installation workers and the construction site environment; 3. the installation defects of the water stop bolt, such as insecure installation, installation position deviation, skew and misplacement, will cause the concrete and the water stop bolt to be unable to effectively bond, resulting in seepage at the water stop bolt of the pool wall; and 4. the water stop effect of the water stop piece alone may not be guaranteed. CONTENT OF THE UTILITY MODEL

[0004] In view of the technical problems existing in the prior art, the purpose of the utility model is to provide a net format water stop bolt system which has simple construction process, high installation accuracy, good integrity and strong bonding with concrete.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0009] As a preferred option, the horizontal channel steel and the vertical channel steel are connected with the steel bars of the pool wall by welding.

[0010] As a preferred embodiment, the transverse channel steel is set along the horizontal direction, and the vertical channel steel is set along the vertical direction; for each transverse channel steel, a set of water-stop bolts and a vertical channel steel are set at intervals.

[0011] As a preferred embodiment, the water-stop bolt includes a threaded rod, and also includes a water-stop plate, an inner nut, a buckle, and an outer nut sequentially fitted onto the threaded rod. The inner nut supports the template, the buckle has a concave opening facing the inner nut, and the outer nut presses the buckle against the template.

[0012] As a preferred option, the screw is a fully threaded screw.

[0013] As a preferred option, the screw is fixed to the transverse channel steel by welding.

[0016] This utility model has the following advantages:

[0017] 1. The mesh-type water-stop bolt system can be prefabricated and then connected to the steel bars of the pool wall. Compared with the existing technology of installing water-stop bolts one by one, the installation accuracy is high and the installation is firm and reliable.

[0018] 2. The multiple sets of water-stop bolts in the grid-type water-stop bolt system are evenly distributed, which facilitates precise drilling of the template and further avoids the water-stop bolts being installed crookedly.

[0019] 3. The mesh-type water-stop bolt system has good overall integrity. The horizontal channel steel, vertical channel steel and multiple sets of water-stop bolts share the force, which can effectively resist the impact of steel bar installation, formwork installation and concrete pouring.

[0024] 8. When designing the water tank, the horizontal and vertical channel steels should be included as part of the tank wall reinforcement, thus reducing the amount of steel reinforcement required. Attached Figure Description
