Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a steel bar cutting device used in building construction. Background Art
[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. During the construction process, the rebar needs to be cut to size for subsequent use. There are at least the following disadvantages in the use of existing rebar cutting devices: 1. The existing rebar cutting device requires workers to drag the rebar during use. Since the mass of the rebar is large and the surface is relatively rough, it is more laborious for workers to drag the rebar; 2. During the use of the existing rebar cutting device, sparks generated during cutting will splash. Since the spark temperature is high, it is easy to scald workers, so protective facilities need to be added. Therefore, we have introduced a new rebar cutting device for construction.
