Description

Technical Field

[0001] The utility model relates to the technical field of steel templates, in particular to a compression-resistant road and bridge steel template structure. Background Art

[0002] Steel formwork is a steel formwork used for concrete pouring and shaping. Other options include wooden and plywood formwork. Steel formwork is widely used in construction projects due to its multiple uses and aesthetically pleasing concrete forms. Conventional concrete pouring requires steel formwork to secure it to the desired shape.

[0003] However, the existing compressive steel formwork structure for road bridges has the following disadvantages:

[0004] (1) The existing compressive steel formwork structure for road and bridges has a weak clamping and fixing function. During use, the steel formwork used for concrete pouring is usually fixed on both sides with bolts. After the concrete is formed, the steel formwork needs to be disassembled. Due to the installation of multiple bolts, the disassembly process is not only cumbersome but also time-consuming.

[0005] (2) The existing compressive steel formwork structure for road and bridges has a weak function of adjusting the support position. When in use, the density of concrete pouring and the weight distribution are different when the steel formwork is supported, and the support position needs to be changed. The support position of the existing technology is usually fixed, so it cannot be adapted and adjusted. Summary of the Invention

[0006] The purpose of the utility model is to provide a compression-resistant steel formwork structure for a road bridge, so as to solve the problems raised in the above-mentioned background technology.

Manually pull the insertion rod to one side, manually adjust the position of the sliding rod inside the fixed frame, and then insert the insertion rod into the positioning hole opened on the sliding rod to fix the position. Since the rotating rod is fixed in the fixing plate, the fixing frame can be fixed and limited, thereby achieving the effect of adjusting its support position according to the installation environment.
