Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a template height adjustment device. Background Art

[0002] Building formwork is a temporary support structure, which is made according to the design requirements to form concrete structures and components according to the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the building formwork and the external loads acting on it. Due to the height difference of the concrete pouring plane, the formwork needs to be calibrated in height during the process of supporting the formwork so that the position of the formwork meets the design requirements. The formwork height adjustment is generally carried out by construction personnel inserting tools such as crowbars into the bottom of the formwork for height adjustment, which can easily cause damage to the inside of the formwork, thereby affecting the quality of the final concrete molding. Moreover, if the calibration does not meet the standard once, the formwork needs to be completely disassembled and re-calibrated. At the same time, since the formwork is a surface material, it lacks a fulcrum and is not easy to adjust manually. As a result, the construction personnel are not only time-consuming and labor-intensive in the process of height adjustment, but also difficult to operate, and it is easy to damage the edge of the formwork, resulting in leakage. Therefore, the prior art provides a device for formwork height adjustment.

Secondly, after the template is raised, it is impossible to determine the raised distance, which is not convenient for subsequent filling of the gap; it needs further improvement.
