Description

Technical Field

[0001] This utility model relates to the field of building construction formwork technology, specifically a multi-positioning hole type steel formwork. Background Technology

[0002] In modern construction engineering, steel formwork is widely used due to its advantages such as high strength, high reusability, and good surface flatness. Traditional steel formwork is usually spliced ​​and fixed by bolt holes or slots on the frame. However, in actual construction, especially when encountering complex structures (such as irregular columns, beams, and wall connections) or when precise pre-embedded components (such as bolts, sleeves, and embedded parts) are required, the following problems exist: Traditionally, embedded parts are fixed to formwork by temporarily drilling holes or welding into the formwork body. This method directly damages the overall structure of the formwork, weakens its local strength, and may leave permanent damage on the formwork surface, affecting the structural quality. Therefore, this utility model proposes a multi-positioning hole type steel formwork. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 As shown, this utility model provides a technical solution: a multi-positioning hole type steel formwork, including a rectangular steel formwork body 1. Multiple equally spaced bolt connection holes 2 are provided on the four sides of the steel formwork body 1 for connecting the steel formwork bodies to each other via bolts. The surface of the steel formwork body 1 has multiple rows and columns of positioning holes 3 arranged in a grid pattern. The small diameter portion of the positioning holes 3 has a diameter of 20-100mm. The positioning holes 3 are stepped through holes. The large diameter hole wall of the through hole has a connecting thread 301, and the small diameter hole wall has a smooth structure. A detachable positioning device 4 is installed inside the positioning holes 3. By using the preset positioning holes and the detachable positioning device, temporary drilling of the formwork for positioning is completely avoided, protecting the overall structural strength and surface quality of the formwork, and significantly extending the service life of the formwork. Furthermore, the grid-like arrangement of positioning holes 3 on the surface of the steel formwork body 1 provides a large number of selectable positions during use. The closest hole position can be selected for installation according to the actual needs of the embedded parts or connectors, making it convenient to use.

[0019] The detachable positioning device 4 in this utility model is a stepped shaft structure, including an insertion section 401, a limiting shoulder 402, and an exposed section 403. The exposed section 403 is a metal ring. The insertion section 401 is adapted to the small diameter part of the through hole. The limiting shoulder 402 is provided with a connecting thread 404. The limiting shoulder 402 is threadedly connected to the large diameter part of the through hole. A sealing ring 7 is provided on the insertion section 401.

[0020] Please refer to the following carefully. Figure 1 The distribution area of ​​the positioning hole 3 is provided with reinforcing ribs 5, and the cross section of the reinforcing ribs 5 is triangular or trapezoidal.

[0021] Please refer to the following carefully. Figure 5The steel formwork body 1 has a connecting positioning groove 101 on its four sides, and also includes a docking block 6 that is adapted to the connecting positioning groove 101. The docking block 6 is detachably installed inside the connecting positioning groove 101.

[0022] Working principle: The core of this steel formwork lies in the numerous positioning holes pre-drilled in a grid pattern on its surface. These positioning holes are stepped through holes, with connecting threads on the inner wall of the larger diameter portion and smooth inner wall of the smaller diameter portion.

[0023] When pre-embedded components are required, operators can select the closest hole from the dense grid of positioning holes according to the actual position requirements of the pre-embedded components. Then, the detachable positioning device 4 can be opened to insert the pre-embedded component into the positioning hole 3. Through this combination of "pre-set grid holes + detachable threaded positioning device", the reusability of the template is achieved, effectively avoiding damage to the template caused by temporary drilling on site. When disassembling the detachable positioning device 4, simply rotate the detachable positioning device 4 to easily remove it from the positioning hole. The entire process does not require any permanent modification to the template body. After the concrete is poured and solidified, the template can be removed and the detachable positioning device 4 can be reinstalled.
