Description

Technical field:

[0001] The utility model relates to the technical field of building construction, in particular to a slitting device for grooving in building construction. Background technology:

[0002] Cutting construction refers to a construction process in which gaps are cut in the concrete structure of a building and then filled and sealed. By cutting the gaps reasonably, the stress on the building can be relieved, the generation and expansion of cracks can be prevented, and the seismic resistance and service life of the building can be improved.

[0003] For example, a slitting device for grooving in construction with the authorization announcement number "CN220903782U" solves the problem of the inconvenience of cutting slits of different depths and the inconvenience of replacing the cutting disk when the slitting device for grooving in construction is working by setting a driving motor, a cutting disk, a protective cover and a bottom contact plate. However, when the device is grooving a building, it is necessary to fit the bottom contact plate with the surface of the building, and then push the device to cut the groove of the building. When the bottom contact plate in the device contacts the uneven surface, it will be lifted up by the protrusions on the surface, causing the device to shake, and the saw disk will be damaged and broken by the torsion, which reduces the safety of the device. At the same time, when the saw disk is replaced, the device needs to fix the saw disk and then rotate the outer rotating frame for disassembly. When the device fixes the saw disk, the operator needs to manually fix it, which makes the device inconvenient to use. Utility model content:
