Problems solved by technology

[0002] The water-stop screw is usually used in the pouring of the basement shear wall to fix the formwork and control the thickness of the concrete pouring. The difference from the ordinary wall-through screw is that there is a water-stop sheet in the middle of the water-stop screw. When removing the formwork, the ordinary wear-through The wall screw is pulled out as a whole and reused. After the two ends of the water-stop screw are sawn off the wall, the middle part is left in the wall to ensure the watertightness of the wall; waste of material
But there is a problem: only the end screw part can be recycled, but the tubular spacer cannot be recycled, which causes waste of materials and increases the cost

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:

[0013] Such as figure 1 The water-stop screw shown in this embodiment includes a handle 1 , a connecting rod 2 , a pulley 3 , a screw 4 , a water-stop sheet 5 , and a foam layer 6 .

[0014] Such as figure 1 , figure 2 As shown, three water-stop sheets 5 with holes are respectively set on the two ends and the center of the screw 4, and then the water-stop sheets 5 are welded on the screw 4, so that there is no gap between the water-stop sheets 5 and the screw 4, To ensure a better water-stop effect, the two ends of the screw 4 are respectively provided with a sleeve 3 that is threadedly connected with the screw 4. When the sleeve 3 and the thread of the screw 4 are in a connected state, the water-stop sheet 4 fits with one end surface of the sleeve 3, and the connection Rod 2 and pulley 3 are integrally designed, which is convenient t...

Abstract

The invention relates to the technical field of a building component, in particular to a water stop screw rod. The water stop screw rod comprises a screw rod, three perforated water stop sheets, connecting rods and handles, wherein the three water stop sheets are tightly connected at the two ends and the middle position of the screw rod; the two ends of the screw rod are provided with sleeve heads connected with the screw rod through screw threads; when the sleeve heads are in a state of being connected with the screw threads of the screw rod, the water stop sheets are attached to the sleeve heads; each connecting rod is arranged on the corresponding sleeve head; a foam layer is arranged on the side surface of each sleeve head; and the handle is arranged on each connecting rod. The water stop screw rod has the beneficial effects that the material recovery of the connecting rods and the sleeve heads arranged on the water stop screw rods is simultaneously realized; and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a water-stop screw. Background technique [0002] The water-stop screw is usually used in the pouring of the basement shear wall to fix the formwork and control the thickness of the concrete pouring. The difference from the ordinary wall-through screw is that there is a water-stop sheet in the middle of the water-stop screw. When removing the formwork, the ordinary wear-through The wall screw is pulled out as a whole and reused. After the two ends of the water-stop screw are sawn off the wall, the middle part is left in the wall to ensure the watertightness of the wall; Caused the waste of material. [0003] The existing solution is a three-stage water-stop screw, which consists of a middle screw connected to two symmetrical end screws. The middle screw is provided with a water-stop piece, and the end screw is provided with a fastening thread and a fastening nut. Th...
