Structure surface treatment device and method

Abstract

The invention provides a structure surface treatment device and method. The structure surface treatment device comprises a device main body, a handheld handle is fixedly connected to the device main body, a switch button and an impact force adjusting button are installed on the device main body on the inner side of the handheld handle, and an impact rod counter-force frame is installed on the inner side of the device main body and close to the handheld handle; the impact rod counter-force frame is connected with a bounce control and recognition device, a plurality of reserved notches are formed in the bounce control and recognition device, round-head impact rods are installed at the reserved notches and can rotate along with rotation of the bounce control and recognition device, and the round-head impact rods can also stretch out and draw back in groove holes of the bounce control and recognition device; and a flexible absorption sleeve is connected to the right end of the device main body, the natural length of each round-head impact rod reaches the interior of the flexible absorption sleeve, a filtering opening is formed in the lower end of the flexible absorption sleeve, and a dust collection channel is connected to the filtering opening. Scabbling processing can be performed on a surface of a structure, and the device 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 and railway bridges, subways, tunnels, seaport terminals, water conservancy and electric power, municipal squares and other cement concrete side facades, top surfaces, etc., and later maintenance and reinforcement, it is often necessary to improve the adhesion of the cement concrete surface, increase The friction between each other can make the new and old cement concrete closely bonded to ensure that the cement concrete is poured in stages to form a whole, so as to avoid the bad bond between the cement concrete of the second overlay and the original cement concrete. In order to prevent the formation of displacement, spalling under the high-speed horizontal thrust and the influence of temperature, the concrete will expand and contract to cause displacement, avoid cracking and deformation of the asphal...

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
