Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a water-stop screw rod for a standardized box-shaped steel formwork. Background Technique

[0002] When building concrete walls, especially for the pool wall and the basement exterior wall, water-stop screw rods are often used to pass through both sides of the formwork to bear loads such as the lateral pressure of the concrete, so as to ensure that the formworks on both the inside and outside meet the design requirements. Installing water-stop screw rods can not only prevent the formwork from bursting during concrete pouring, but also play a role in preventing leakage of the basement exterior wall and the pool wall.

[0003] For the spacing of the water-stop screw rods passing through the wooden formwork, it is generally set between 400 MM and 500 MM. Due to its own load and other reasons, when using ordinary water-stop screw rods for steel formworks, the spacing will be less than the generally set distance to ensure the stability of the steel formworks. Therefore, when using ordinary water-stop screw rods for steel formworks, not only the number of ordinary water-stop screw rods used increases, but also the number of screw holes on the steel formworks increases, resulting in increased costs; if the steel formworks do not use water-stop screw rods, although the waterproof function is good after the wall is formed, during the construction process, it is necessary to constantly pay attention to whether the steel formworks are laterally fixed, and additional fixed support measures are added to the sides of the steel formworks, which will greatly increase the construction time and even increase the cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water-stop screw rod for a standardized box-shaped steel formwork, which can reduce the number of holes opened on the steel formwork through the water-stop screw rod of the special steel formwork, ensure the pulling and fixing effect on the steel formwork, and reduce the leakage situation of the pool wall, basement exterior wall, etc. during long-term use, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water-stop screw rod for a standardized box-shaped steel formwork, including a gasket, a bolt, a bolt head, a washer ring and an inner threaded rod. The inner threaded rod is connected to the screw rod of the bolt head through an internal thread; the washer ring is placed inside the hole of the standardized steel formwork, and both ends of the washer ring are fixed to the bolt head; the gasket is placed outside the hole of the standardized steel formwork, and the bolt passes through the gasket and is connected to the internal thread of the bolt head.

[0006] Preferably, the standardized steel formwork is pre-drilled with holes having a diameter of 30 mm at a spacing of 1 m in both the horizontal and vertical directions.

[0007] Preferably, the gasket is located below the bolt, and both the gasket and the bolt are located outside the standardized steel formwork.

[0008] Preferably, the gasket ring is in an annular structure, with a small diameter of the ring being 30 mm and a large diameter being 40 mm, and the hollow area overlapping with the holes of the standardized steel formwork.

[0009] Preferably, the bolt head includes a conical plastic plug, a screw rod, a nut head, and an internal thread; the conical plastic plug is wrapped outside the nut head for protecting the nut head, and the nut head is hexagonal with an internal thread provided inside.

[0010] Preferably, the inner screw rod includes a round rod, a water stop piece, and an internal thread. The water stop piece is welded in the middle area of the round rod, and the internal threads are located at both ends of the round rod and are connected to the screw rod.

[0014] 3. The water stop screw rod for the standardized box-shaped steel formwork is designed with a conical protection plug on the bolt head, effectively protecting the bolt head, which can be taken out after the steel formwork is removed, realizing the recycling of materials.

[0015] 4.
