Wall-Penetrating Pipe Sockets / Wall-Penetrating Pipe Rubber Cups: Stable Fixing Devices for High-Strength Screw Rods
In construction, the connection and fixation of wall-penetrating pipes and high-strength screw rods are key links to ensure the stability of the formwork support system. Wall-penetrating pipe sockets and wall-penetrating pipe rubber cups (often mentioned together due to their similar shapes and application scenarios) are plastic components specially designed for this need. With precise size adaptation and reliable material performance, they provide solid support for high-strength screw rods and ensure structural safety during construction.
I. Material Characteristics: A Balance between Lightweight and Durability
This type of fixing device is injection-molded from high-strength plastic, and the material selection fully considers the needs of the construction environment:
- The plastic material has moderate hardness and toughness, which can not only bear the pressure transmitted by the high-strength screw rod but also maintain structural integrity during installation and disassembly, and is not easy to break;
- Compared with metal materials, plastic is lighter, which is convenient for transportation and on-site operation. At the same time, it avoids the problem of rust and can maintain stable performance in humid environments for a long time;
- Its surface is smooth, and the friction coefficient with the screw rod is moderate. It will not cause difficulty in installation due to being too tight, nor will it affect the fixing effect due to being too loose, ensuring that the screw rod does not loosen or shift during use.
II. Core Purpose: Focus on Precise Fixing of Screw Rods
The core function of wall-penetrating pipe sockets/wall-penetrating pipe rubber cups is to fix the high-strength screw rods in the wall-penetrating pipes, and their specific roles are reflected in:
- During formwork installation, they are embedded in the preset position of the wall-penetrating pipe, and through their own structural design (such as inner wall 卡槽 (clamping grooves) or tight-fitting structure), they are closely connected with the high-strength screw rod, restricting the axial and radial displacement of the screw rod, ensuring that the screw rod remains vertical and stable when bearing the pressure of concrete pouring;
- They form a synergistic effect with the wall-penetrating pipe, preventing concrete slurry from leaking from the gap by filling the gap between the pipe and the screw rod, ensuring the forming quality of the wall or component;
- For reusable screw rods and wall-penetrating pipes, this type of plastic fixing device can reduce wear between components, prolong their service life, and reduce construction costs.
This targeted fixing function makes it widely used in the construction of concrete components such as shear walls, beams, and columns that require wall-penetrating screw reinforcement, and it is an indispensable auxiliary accessory for the formwork support system.
III. Specification Sizes: Adapting to Different Screw Rod Diameters
To meet the fixing needs of high-strength screw rods with different diameters, the product provides two standardized sizes:
- 19mm: Suitable for high-strength screw rods with a diameter of 18-19mm, commonly used in small and medium-sized formwork support systems, such as the construction of civil buildings with thin wall thickness;
- 22mm: Corresponding to screw rods with a diameter of 21-22mm, suitable for formwork support with large loads, such as the construction of large beams, thick walls and other components, and can provide stronger bearing capacity and stability.
The inner wall precision of both sizes is strictly controlled to ensure close cooperation with the corresponding screw rods, achieving the precise fixing effect of "one diameter, one fit".
Summary
Although wall-penetrating pipe sockets/wall-penetrating pipe rubber cups are small plastic components, they play a key role in the details of formwork support. With a simple design, they realize the stable fixing of high-strength screw rods, and with lightweight materials, they bear the responsibility of structural safety, reflecting the practical value of "seeing the big from the small" of building accessories. In modern construction pursuing efficiency and safety, such products focusing on detail fixing provide a solid guarantee for the reliability of the formwork system.
