Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, and particularly relates to a water stop screw. BACKGROUND

[0002] The water stop screw is a building accessory applied to the construction of a concrete wall with waterproof requirements, which is composed of a screw with a water stop piece welded at the middle part, and a positioning piece and a nut matched at both ends. During the pouring operation of the concrete wall, the water stop screw penetrates through the wall formwork to play a role of fixing the formwork, effectively preventing the formwork from deforming or swelling during the pouring process. The core function of the water stop screw is to stop water, and the water stop piece blocks the penetration channel formed along the screw, effectively preventing the underground water or other water sources from leaking through the screw hole of the concrete wall, and thus the water stop screw is widely applied to the building parts with waterproof performance requirements such as basements, pools, civil air defense projects and the like.

[0003] The three-section water stop screw is a type of existing water stop screw, which is usually composed of a middle section, two end screws and a connecting part assembly. The middle section is a water stop screw body with a water stop piece, and the water stop piece is usually circular or square, and is tightly welded with the screw to effectively prevent the penetration path of water. The two end screws are connected with the middle section through the connecting part, and the connecting mode can adopt threaded connection or other detachable connection forms convenient for construction operation. The connecting part generally adopts a plastic cone or other detachable structure, and its function is to facilitate the removal of the two end screws from the wall after the pouring of concrete is completed, so as to realize recycling. However, in actual construction, when the concrete covers the contact part of the screw and the connecting part, the locking phenomenon is easy to occur, which causes the two end screws to be unable to be taken out or difficult to be taken out, and there is a problem of poor practicability.

[0024] When the water stop screw is used, the water stop screw is first positioned on a wall formwork, the two side screws 8 are arranged to pass through the wall formwork, and the middle section screw 1 and the connecting assembly are arranged in the wall formwork, then the mountain-shaped clamping pieces 7 are locked and fixed through the locking nuts 10, at this time, the rubber sleeve 6 is tightly connected with the inner side of the wall formwork under the action of the elastic force of the rubber sleeve 6, the rubber sleeve 6 protects the connecting position of the ring-shaped connecting piece 5 and the side screw 8, and the contact position of the side screw 8 and the ring-shaped connecting piece 5 in the wall formwork can be effectively prevented from being covered by the concrete in the concrete pouring process, so that the locking phenomenon in the traditional connecting structure is avoided, and the side screw 8 is more easily removed in the subsequent removal process, which is beneficial to realize the recycling and improve the practicability and economy of the water stop screw.

[0025] It is worth noting that the inner side of the wall formwork is connected with the side of the ring-shaped connecting piece 5 to determine that the wall formwork is installed in place.

[0026] As a preferred embodiment, the rubber sleeve 6 is conical, and the small-diameter end of the conical rubber sleeve 6 is connected with the first water stop piece 2 or the second water stop piece 3.
