Description

Technical Field

[0001] This utility model belongs to the technical field of tensioning slots, specifically, it relates to a detachable tensioning slot template. Background Technology

[0002] In construction engineering, formwork plays a crucial role as a tool for bearing and supporting poured concrete. The design and application of formwork systems directly affect the quality and construction efficiency of the project. With the development of construction technology, the types and functions of formwork have become increasingly diverse. Among them, detachable tensioned slotted formwork, as a new type of formwork design, has gradually become one of the most widely used pieces of equipment in modern construction.

[0003] Traditional formwork systems typically use wood or steel. While these forms can meet basic construction needs, they have shortcomings in terms of construction efficiency, formwork reuse rate, and safety. For example, the installation and dismantling of traditional formwork usually requires a significant amount of manpower and time, and the frequency of formwork reuse is low, resulting in substantial waste. Furthermore, traditional formwork is often unstable, leading to displacement or deformation during construction, which affects the concrete pouring effect.

[0004] To address the aforementioned issues, detachable tensioned slotted formwork has emerged. This formwork system is designed to improve the ease of installation and disassembly, as well as enhance its load-bearing capacity and stability. The tensioned slotted formwork is tensioned and fixed by a tensioning mechanism, ensuring stability during pouring and effectively preventing displacement or deformation, thus guaranteeing the accuracy and construction quality of the concrete structure.

[0005] Traditional formwork mostly adopts a simple fixed design, making it difficult to adjust the shape and size of the formwork as needed, thus failing to adapt to different types of construction requirements and resulting in low construction efficiency. Utility Model Content

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting a cross groove of appropriate depth, it is easy to tighten and disassemble without affecting the strength of the bolt.

[0025] Furthermore, the fixed base is made of high-strength alloy steel, and the yield strength of the high-strength alloy steel is not less than 400MPa.
