Description

Template in concrete floor falls board area

Technical Field

The utility model relates to the technical field of building construction, in particular to a template of a concrete floor slab descending area.

Background

In the construction of the residential building, the factors of water resistance, pipeline laying and the like are considered in the toilet and the kitchen, and generally, a floor plate lowering measure is adopted, namely, the floor plate in the toilet and the kitchen area is lowered by about 5cm compared with the floor plate in the living room (or bedroom) area, and a template needs to be independently erected in the floor plate lowering area. However, due to the reasons of different specifications and sizes of wood beams, rough surface, low material rigidity and the like, the quality defects of poor concrete forming quality, insufficient height difference, edge missing, corner falling and the like are caused.

And after the forming, mortar needs to be applied to the internal corner part to form an arc shape, which is a premise of ensuring the construction quality of the waterproof coating, however, the mortar amount needed in the process of processing the arc at the internal corner is less, so that the phenomena of poor arc forming quality and weak adhesion with concrete are easy to occur. To this end, we propose a form for the slab-dropping area of a concrete floor.
