Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, in particular to a casting mould with a stable structure used for building a roof. Background Art

[0002] With the development of construction engineering, the construction method of buildings has also changed. Among them, cast roof is a relatively new roof construction method, which has the advantages of fast construction speed and strong structure. At the same time, the whole roof will be connected as a whole, so its seismic performance will be greatly improved. It is an ideal alternative construction method for prefabricated panels. In the construction process of cast roof, casting molds will be used, and the casting molds are generally called templates;

[0003] The existing document with publication number CN210738076U discloses a formwork for pouring roof concrete on site, including two formworks connected by hinges to form an integral formwork;

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The two adjacent sides of the above-mentioned formwork for pouring roof concrete on site are straight, and the other two adjacent sides are provided with steps. There is no structure for quickly connecting the two integral formworks, which makes it inconvenient to splice the integral formworks.

[0006] 2. The above-mentioned formwork for pouring roof concrete on site, its overall formwork is composed of two formworks movably connected by hinges, and the axis of the hinges is arranged below the overall formwork. The setting of the hinges facilitates the folding of the overall formwork for storage. However, during use, due to the presence of the hinges, the connection between the two formworks is less stable, and the pressure of the concrete may cause relative rotation between the two formworks.

[0007] To this end, we provide a casting mold with a stable structure for building a roof to solve the above-mentioned problems. Utility Model Content
