Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to an anti-leakage wall-penetrating bolt. Background Art

[0002] At present, bolts, as a fastener, are widely used in production and life. Through-wall bolts are used to tie the inner and outer wall formworks, bear the lateral pressure of concrete and other loads, ensure that the spacing between the inner and outer formworks can meet the design requirements, and are also the fulcrums of the formworks and their supporting structures. The arrangement of through-wall bolts has a great influence on the integrity, rigidity and strength of the formwork structure.

[0003] During formwork construction, ordinary tension bolts will produce deflection and deformation, which will lead to water seepage and have an adverse effect on the waterproofing of the project. Ordinary tension bolts will be removed after the pool formwork and wall bolts are poured after the concrete is poured, and then waterproof blocking will be carried out.

[0004] However, if the conical groove is not waterproofed and blocked as required after the detachable through-wall bolt is removed, a certain amount of leakage will occur at the position of the through-wall bolt. Utility Model Content

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom" and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0032] The utility model discloses an anti-leakage through-wall bolt, comprising an inner screw 1 and two outer screws 2, wherein the inner screw 1 is a double-headed screw with threads on both sides, the two outer screws 2 are arranged on both sides of the inner screw 1, a fixing assembly 3 is arranged between the inner screw 1 and the outer screw 2, the fixing assembly 3 comprises two connecting pieces 31 which are threadedly connected to both ends of the inner screw 1, the connecting piece 31 is in a truncated cone shape, one end of the two connecting pieces 31 with a small diameter is threadedly connected to both ends of the inner screw 1, and one end of the two connecting pieces 31 with a large diameter is threadedly connected to the outer screw 2, and a side of the connecting piece 31 away from the inner screw 1 is provided with Hexagonal hole 32 is a through hole. The hexagonal hole 32 is set so that after the pouring is completed, the external screw 2 can be taken out first, and then the connecting piece 31 can be taken out through the hexagonal hole 32. This is convenient for next use and better material saving. A groove 33 is set on the surface of the connecting piece 31 close to the template, and a hanging rod 34 is set in the groove 33. Both ends of the hanging rod 34 are fixedly connected to the inner wall of the groove 33. A groove 33 is set on the surface of the connecting piece 31 close to the template, and a guide rod is set in the groove 33. This is to facilitate the removal of the connecting piece 31 and prevent the connecting piece 31 from being stuck in the wall.

[0033] The two ends of the outer screw 2 are provided with fastening nuts 4, which are threadedly connected to the outer screw 2. An anti-seepage structure 5 is arranged between the fastening nut 4 and the fixing assembly 3, and a template is arranged between the fixing assembly 3 and the fastening nut 4. The anti-seepage structure 5 includes a sealing ring 51 arranged on the side of the template away from the fixing assembly 3. When concrete is poured from the middle of the two templates, the template will be subjected to pressure. At the same time, because the fastening nut 4 is threadedly connected to the outer screw 2, the sealing ring 51 will be squeezed at this time. Therefore, a sealing ring 51 made of rubber material is used to make the sealing ring 51 more tightly connected to the template to achieve the anti-seepage effect proposed by the utility model. A gasket 52 is arranged between the sealing ring 51 and the fastening nut 4. The gasket 52 is arranged slightly larger than the sealing ring 51, so as to better bear the force on the sealing ring 51. The sealing ring 51 is annular, and the center points of the fastening nut 4, the gasket 52, the sealing ring 51 and the connecting piece 31 are on the same horizontal line.

[0034] A waterstop structure 6 is arranged in the middle of the inner screw rod 1, and the waterstop structure 6 includes a waterstop plate 61 welded at the center of the inner screw rod 1. The waterstop plate 61 is arranged so that after the wall is cast and the through-wall bolts are removed, the inner screw rod 1 remains in the wall. The waterstop plate 61 on the inner screw rod 1 can prevent leakage. The waterstop plate 61 is welded on the inner screw rod 1 to prevent water leakage in the gap between the waterstop plate 61 and the inner screw rod 1. The waterstop plate 61 is circular, and both sides are concave surfaces. The concave curved waterstop plate 61 increases the contact area between the waterstop plate 61 and the concrete, and increases the water flow path, thereby preventing water leakage.

[0035] Working principle: The utility model discloses an anti-leakage through-wall bolt. Before pouring the wall, the anti-leakage through-wall bolt is first installed through the template. The inner screw 1 and the outer screw 2 are respectively threadedly connected to the connecting piece 31, and then the gasket 52, the sealing ring 51 and the template are fixed together by the fastening nut 4. At this time, the assembly is completed and then pouring is carried out. After the pouring is completed, the wall is formed. First, the outer screw 2 is unscrewed from the wall, and then the template is removed. The connecting piece 31 is taken out through the hexagonal hole 32 and the groove 33, and the inner screw 1 is left in the wall. Then, the uneven parts of the wall are sealed with dry hard waterproof mortar and compacted and smoothed.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
