Technical Field

The utility model belongs to the field of buildings, and particularly relates to an outer wall dismantling-free template system.

Background

The above-ground construction has the requirement of building industrialization, and in the region with high assembly degree, the prefabricated shear wall and the prefabricated outer wall are widely used, so that the construction speed and the construction quality are greatly improved, but the prefabricated shear wall and the prefabricated outer wall are not applied to the basement part. In order to really apply the building industrialization to the whole project, if the cast-in-situ outer wall of the basement is changed into a prefabricated outer wall, the weight of the component per se is large according to the thickness, the width and the distribution range of the outer wall of the basement, and the requirement on the construction tower crane is extremely high.

The problems of the weight of the prefabricated component and the positioning accuracy of the mounting embedded part in the industry are solved, and an SPCS system and a double-skin wall system are also provided, namely a cavity component, a lap joint steel bar and cast-in-place concrete are simply described, but the production of the component needs to adopt a turnover process and has requirements on equipment; and the running time is different from that of other prefabricated components, and a production line is required to be independently arranged.
