A structure surface treatment device and method

Abstract

The invention provides a structure surface treatment device and method, comprising a device main body, a hand-held handle is fixedly connected to the device main body, a switch button and an impact force adjustment button are installed on the device main body inside the hand-held handle, and the inner side of the device main body is installed close to the hand-held handle. There is an impact rod reaction frame, which is connected with the rebound force control identification device. There are multiple reserved slots on the rebound force control identification device, and round head impact bars are installed on the reserved slots. The impact rod can rotate with the rebound force control identification device, and the round head impact rod can also be stretched and changed in the slot hole of the rebound force control identification device. The right end of the device main body is connected with a flexible absorption sleeve. The natural length of the round end impact rod reaches In the flexible absorption sleeve, the lower end of the flexible absorption sleeve is provided with a filter port, and the filter port is connected with a dust suction channel. The invention can chisel the surface of the structure, is simple to use, convenient to carry, safe and environment-friendly.

Description

technical field [0001] The invention specifically relates to a structure surface treatment device and method. Background technique [0002] In cement concrete pavement, highway, railway bridge, subway, tunnel, harbor wharf, water conservancy and electric power, municipal square and other cement concrete side elevation, top surface and other plane construction and later maintenance and reinforcement, it is often necessary to improve the adhesion of the cement concrete surface, increase the The friction between each other, so that the old and new cement concrete can be closely combined to ensure that the cement concrete is poured in stages to form a whole, so as to avoid poor adhesion between the cement concrete and the original cement concrete. In order to prevent displacement, spalling, and the influence of air temperature when subjected to high-speed horizontal thrust, the concrete expands and contracts to cause displacement, and the asphalt concrete on the bridge deck is p...

Problems solved by technology

These two methods are backward in technology, easy to operate, unprofessional, irregular, and the number of workers invested is large, labor intensity is high, and efficiency is low. It is difficult to achieve the treatment of roughening (roughness) on the surface of cement concrete Can not meet the technical requirements of bridges, highway tunnels and other operations, the third is to use other machinery instead of chisel machines, such as: milling machine, shot blasting machine, etc., use these machines to chisel hair processing, although these devices can achieve a certain degree of roughness But the disadvantages are: such as milling machine, the milling depth is too deep, the chip and vibration force are too large, and there are too few chiseling points; another example is the shot blasting machine, the working surface is flat and beautiful after construction, but the chiseling depth is shallow, and the concave and convex are hemp Face is not obvious
