Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a construction engineering block cutting device. Background Art

[0002] In the construction process of building projects, blocks are a kind of building material, which are cast and mixed with lime, cement, gypsum and slag as the main raw materials. In order to meet the needs of construction, it is often necessary to cut the finished blocks for use.

[0003] The cutting methods in the prior art are generally divided into manual cutting and electric cutting. The traditional manual block cutting method often uses a heavy hammer to hit and then form a fracture cut. This cutting method not only has uneven cut surfaces, but also has poor control over the block cutting size. The cut blocks are often unusable, resulting in serious waste of blocks. At the same time, manual cutting also has a high labor intensity for construction workers and low work efficiency. Electric cutting generally uses an electric saw. Construction workers often support the cut blocks with one hand and hold the electric saw with the other hand for cutting. However, the blocks are still unstable and easily offset, and are easily exposed to great safety hazards for construction workers. Cutting dust is also easy to splash and is not easy to clean and collect. Utility Model Content
