Description

Technical Field

[0001] The utility model relates to the technical field of concrete slabs, in particular to a concrete slab edge cutting device. Background Art

[0002] Concrete slabs are prefabricated reinforced concrete slabs. In house construction, there are mainly wall slabs, floor slabs and roof slabs; these three types of slabs can sometimes be used interchangeably. Concrete slabs are mainly divided into two categories: reinforced concrete and prestressed concrete. Some also use other reinforcement materials, such as wire mesh, steel fiber or other fibers.

When the next cut is made, the concrete slab is directly placed on the cutting table. The dust residue is between the concrete slab and the cutting table, which will cause the concrete slab to shake during the cutting process, affecting the cutting effect of the concrete.
