Description
Technical Field
The utility model belongs to the technical field of the building templates.
Background
At present, in the construction process of a building outer wall, templates are generally installed on the front side and the rear side of a position where a wall body needs to be built, and then concrete is poured between the two templates. And after the concrete is solidified, removing the template, attaching a heat-insulating material and a fireproof material to the outer side of the wall body, and finally coating a plastering mortar layer.
When the method is adopted for wall construction, the template needs to be installed firstly, the template is dismantled after concrete is poured and solidified, and then the heat-preservation and fireproof materials are attached, so that the process is more, the construction difficulty is high, and the wall construction efficiency is lower. Because the heat insulation material and the fireproof material are directly attached to the wall, the connection strength is not enough, the heat insulation material and the fireproof material are exposed outside the wall for a long time, the falling phenomenon is easy to occur, and the potential safety hazard is existed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a template is exempted from to tear open for building to the outer joint strength who solves current building templates is the problem that drops easily inadequately.
