Description

Assembled cast-in-place mesh structure

This creation is about the construction method of a building frame, especially a fabricated cast-in-place mesh structure.

The domestic building structure is generally made of steel or steel reinforced concrete structure. During construction, the steel bar or section steel can be pre-prepared for the specification of the material outside the construction site, and then transported to the site to work with the heavy machinery. However, the formwork part, Not only can it not be pre-processed outside the site, but it can't be combined with heavy machinery at the site, so it needs to be put into a lot of manpower assembly; and it is easy to be affected by the unevenness of the workers, resulting in many construction problems, such as increasing the rate of template material teardown, The explosion mode, the skew of the template are serious, the construction period is extended, and so on. Moreover, the traditional formwork method includes at least the technical workers such as transportation, nail mold, demoulding, and steel bar binding. The technicians need to be implemented by relevant professionals, and the wage cost of the technician is relatively high. Therefore, if the implementation of the dependent technical workers can be reduced, the construction cost can be greatly reduced. In addition, after the concrete is dried and the formwork of the wall is removed, the wall surface must be treated with secondary construction to make it flat. Can continue the follow-up construction, such as the tile or lacquering on the wall, so the traditional wall pouring construction is a cumbersome and time-consuming task, if it can provide a simple, can shorten the wall construction free of the template, Significantly reducing construction costs is positive.
