Description

Technical Field

[0001] The utility model relates to the measurement of installation position data of a structural formwork in engineering construction, in particular to a steel formwork prism fixing device. Background Art

[0002] During the construction process, the shape of the structure seriously affects the quality of the project, so the acceptance of the structure formwork is particularly important, and there are strict requirements for relevant measurement systems and tools. At present, the usual practice is to directly set up the total station prism at the corner of the steel formwork. If the position of the steel formwork is small, two people are required to cooperate, one to stabilize the prism angle, and the other to set up the prism, adjust the horizontal bubble to the center and start measuring. Affected by the height and shape of the structure, in most cases the measurement work can only be completed by one person. Because the contact surface between the head of the prism rod and the steel formwork is small, the prism is easy to fall off during the process, and the prism bubble is difficult to center. The measurement process is time-consuming and labor-intensive, the process is complicated, and manpower and material resources are wasted, and there is a great safety risk in high-altitude operations.
