Background
In the concrete construction process, before concrete is poured on old concrete, the surface of the old concrete is treated, and rough surfaces or dents are chiseled on the surface of the old concrete, which is commonly called chiseling. At present, in the construction of building engineering, the roughening of concrete is usually carried out by using a heavy roughening machine or manually using an air pick. The two roughening methods have the following disadvantages in use respectively: the use of a chiseling machine for chiseling has the disadvantages of high cost, heavy machine, great machine loss, and unsatisfactory chiseling effect, and is not suitable for chiseling high-strength concrete such as C50; the manual air pick has low roughening construction speed, larger dust, environmental pollution, harm to constructors and unsatisfactory roughening effect, and is not suitable for roughening high-strength concrete such as C50 and the like. In summary, the construction method adopted by the prior small-area concrete chiseling in the construction of the building engineering is generally not applicable, particularly, the high-strength concrete chiseling construction is difficult, the chiseling depth is not enough, the surface is not uniform, the effect is not ideal, meanwhile, the dust is large, and the chiseling cost is high.

Detailed Description
The invention is further illustrated below with reference to the figures and examples.
As shown in fig. 1 to 4, a netting gear for chiseling comprises a steel wire rope 1, an iron block 2 and a connecting piece, wherein the iron block 2 can be arranged on the steel wire rope 1. The steel wire rope 1 can be a common steel wire rope in the market, and the diameter of the steel wire rope is selected according to the roughening requirement; the steel wire ropes 1 are connected into a net shape through the connecting pieces, the steel wire ropes 1 are fixed together in a movable connection mode, and preferably, the connecting pieces comprise connecting pieces I3-1 with rope guide grooves and connecting pieces II 3-2 with the rope guide grooves, the rope guide grooves of the connecting pieces I3-1 and the rope guide grooves of the connecting pieces II 3-2 are arranged oppositely, and the rope guide grooves of the connecting pieces I3-1 and the rope guide grooves of the connecting pieces II 3-2 are in a cross-shaped intersection relationship. The steel wire rope 1 penetrates through the rope guide grooves of the corresponding connecting pieces to be strung into a net shape, and the connecting piece I3-1 and the connecting piece II 3-2 which are matched are fastened through screws. The steel wire rope 1 can also be fixed into a net shape by adopting an iron wire binding mode. When the net is stored, the net can be rolled up for the next use, and when the net is connected by the connecting piece, the connecting piece can be opened to draw out the steel wire rope. The steel wire ropes can be movably connected by using the connecting pieces, so that the steel wire ropes are convenient to use repeatedly, the netting gear is convenient to disassemble, assemble, store and store, and the steel wire rope netting gear is wide in application range; the movable connection mode is convenient for adjusting the matching of the netting gear and the mesh size or the diameter of the steel wire rope according to different construction requirements.
