Abstract

The utility model provides a simple and environment-friendly quick cutting tool for an external wall thermal insulation material, and solves the problem that the wall surface near a rear embedded plate is not covered or the rear embedded plate is covered easily because a paper cutter, a cleaver and other tools are generally used for cutting the thermal insulation plate at present. The cutting device comprises a cutting frame which is connected end to end, the cutting frame is of a vertically-through structure, and a cutting edge with a narrow lower portion and a wide upper portion is arranged at the lower end of the cutting frame. A cross beam extending in the left-right direction is fixedly arranged at the top of the cutting frame, and the middle of the cross beam arches upwards to form a handle higher than the top of the cutting frame. By using the cutting frame, the insulation board at the position of the rear embedded board can be quickly cut off, the insulation board is prevented from being cut for many times in the construction process, and the construction efficiency is improved. After the component at the position of the rear embedded plate is welded, the cut-off heat preservation material can be used for covering the exposed rear embedded plate again, the heat preservation effect at the position of the rear embedded plate is guaranteed, and meanwhile material waste is further reduced.
