Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a construction waste recycling device for building construction. Background Art

[0002] During the construction process, a lot of construction waste will be generated, including a lot of discarded metal pipes, steel wires, fine steel bar scraps and other recyclable materials. These construction wastes have a high recycling value. Therefore, in order to reduce costs, it is necessary to use construction waste recycling equipment to process and recycle the above waste.

[0003] In the Chinese utility model patent with publication number CN219898478U, a construction waste recycling device for building construction is disclosed, which can be inserted and limited between the limiting mechanism and the plug hole through the operation of the limiting mechanism, so as to limit and fix the baffle plate 1 and the baffle plate 2, thereby effectively avoiding the problem of gaps between the baffle plate 1 and the baffle plate 2 due to excessive vibration force. In this way, dust overflow can be effectively avoided, and the safety of the operator can be warned at all times. It is easy to operate and relatively simple, and the practicality is enhanced.
