Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a permanent side beam reinforcement device. Background Technology

[0002] Rapid economic and social development, coupled with the promotion of national fitness, has led to an increasing number of people participating in sports activities, thereby driving the construction and development of sports venues. The structural facilities used to shape concrete are called formwork. The grandstand area of ​​a sports venue project is an example of concrete poured using formwork. Figure 5 The structure shown.

[0003] In actual construction, it is often necessary to fix the side formwork of the side span beam so that concrete can be filled between the side span beam and the formwork. To prevent the side formwork from shifting during the concrete filling process, which could lead to irregular wall formation or other quality problems, the side formwork needs to be reinforced and positioned before construction. Fixing the top of the side formwork of the side beam is difficult and prone to bulging, resulting in poor concrete forming quality. For example, Chinese patent application number 202120186766.9 discloses a side formwork fixing device for reinforcing the bottom and side formwork of a side span beam. The device includes a bottom assembly, a side tension assembly, and a hollow tube. The bottom assembly is installed on the bottom formwork and has threaded holes facing the side formwork. The side tension assembly includes a tension rod with one end passing through the side formwork and connected to the threaded hole, and a limiting assembly installed at the other end of the tension rod. The limiting assembly is located on the outside of the side formwork away from the bottom assembly and is suitable for reinforcing the side formwork. The hollow tube is sleeved outside the tension rod, with one end abutting against the side formwork and the other end extending to the end face of the bottom assembly. This utility model provides a side formwork fixing device that solves the problems of easy deformation and displacement of the side formwork during fixing, uneven wall surfaces, and material waste.

[0004] In the above scheme, after cutting and demolding, some of the side tie rods act as reinforcing bars in the concrete. However, under the influence of metal corrosion and physical vibration during long-term use, the reinforcing bars will separate from the concrete and are prone to movement, resulting in reduced safety. Moreover, the cutting residue cannot be used, causing a certain degree of resource waste.

[0005] Therefore, it is necessary to invent a permanent side beam reinforcement device to solve the above problems. Utility Model Content
