Abstract
The invention belongs to the technical field of building materials and particularly relates to a construction method of performing anticorrosive pretreatment on building bars; according to the method, by adopting a mechanized spraying mode, anticorrosive paint is sprayed to surfaces of the building bars to form a high-strength compact anticorrosive protection layer. The anticorrosive paint for the building bars, adopted by the invention patent, is good in peaceability, not easy to sag after being mechanically sprayed to the surfaces of the building bars, and has very good adhesive power with the surfaces of the building bars; meanwhile, the paint is fast in setting time; the anticorrosive paint formed after setting is compact in structure, and has very good chloride penetration resistance, and meanwhile, the binding power between the anticorrosive paint and subsequent poured concrete is very good. The construction method provided by the invention can be directly used for performing spraying treatment on the bundled building bars directly at the construction site by adopting the mechanized spraying process, is especially suitable for the anticorrosive pretreatment on the building bars in marine concrete, and is easy in preparation method and broad in application.
Description
Technical field:
Patent of the present invention belongs to building material technical field, is specifically related to a kind of construction method of building iron anticorrosive paint.
Background technology:
Along with the fast development of China's engineering construction, the application of concrete particularly this kind of Foundation Design material of steel concrete is more and more extensive, plays very important effect in foundation of national economy construction.But while reinforcing bar applies increase in concrete, the possibility of Rust of Rebar in Concrete is caused also to increase sharply due to multiple environmental factor, such as: accelerate concrete carbonization process due to the day by day serious of automobile exhaust pollution in city, winter North City use Snow Agent in a large number and cause harmful salt to road and bridge concrete Eroded, particularly in region, coastline, because chloride permeability contained in sea wind and seawater is in concrete hole, and cause Rust of Rebar in Concrete so that cause destroying concrete structure phenomenon get more and more, so the antirust ability improving reinforcement in concrete has very important Social benefit and economic benefit.
To this, the what is called " 5 times of laws " of the prevention Rust of Rebar in Concrete that American scholar proposes has certain directive significance to the construction of steel concrete and maintenance, also namely if in the building course of steel concrete, increase the antirust treatment of 1 dollar, just can avoid and reconstruct or keep in repair required 125 dollars after the complete corrosion of reinforced concrete such as saving.
At present; at home and abroad engineering circles has and utilizes the organic materials such as epoxy resin to carry out the case of sprayed protection to building iron in factory in advance; but because this material is not only on the high side, and from factory to concreting before to experience transport and (easily cause flexural fatigue to be destroyed! ), cutting (forms new fracture! ) and tie up (coating friction destruction! ) etc. multiple working procedure, these processes all can produce adverse influence to reinforcing bar coat, the organic material surfaces such as the epoxy resin in addition after sclerosis are more smooth, and with after-pouring concrete between bond stress poor, so the precoating technology utilizing the organic materials such as this based epoxy resin to carry out batch production fails to be applied widely.
Compared with artificial brushing anticorrosive paint, mechanically spraying possesses skills and advantage economically.Mechanically spraying not only speed is fast, and work efficiency is high, and discharging is simultaneously even, and impact force is large, strong adhesion, not easily occur the quality problems such as hollowing and cracking.
Therefore, research and develop a kind of construction method carrying out the building iron anticorrosive paint of coating fast at building-site to the reinforcing bar tied up to be of great practical significance.
Patent of invention content:
The object of patent of the present invention is to overcome prior art Problems existing, provides a kind of building iron anticorrosive paint in the construction method of building-site to replace existingly carrying out antiseptic technology in factory to reinforcing bar.
Patent of the present invention adopts the method for mechanically spraying, at building-site, anticorrosive paint is sprayed to rebar surface, forms a kind of corrosion protective covering of high densification.This steel bar anti-corrosion coating workability is good; not easily sagging after mechanically spraying to rebar surface; good adhesion is had with rebar surface; setting time is fast simultaneously; the reinforcing bar coating layer formed is fine and close; there is the ability of good chloride-penetration resistance, can more effectively protect the reinforcing bar in concrete structure from the erosion of extraneous hazardous medium.
Patent of the present invention compared with prior art has following advantage:
1, because patent of the present invention can directly adopt mechanically spraying operation at building-site, improve operating efficiency, shorten the construction period.
2, the steel bar anti-corrosion coating adopted due to patent of the present invention has good workability and pumping, after spraying to rebar surface, has good adhesive capacity, return bullet amount few by the mode of mechanically spraying.
3, the steel bar anti-corrosion coating solidification time adopted due to patent of the present invention is fast, and intensity is good, therefore can be used for fast construction and the repairing operation of steel concrete.
4; due to compact structure after the steel bar anti-corrosion coating solidification that patent of the present invention adopts; not only there is good bond stress with reinforcing bar; also there is good adhesion strength simultaneously and between follow-up built concrete; the reinforcing bar coating layer formed is fine and close; there is the penetrating power of good resisting chloride ion penetration, the reinforcing bar in concrete structure can be protected better from the erosion of chlorion in air and seawater etc.
5, because the raw material of patent of the present invention and equipment all adopt market finished product, be applicable to extensive use.

Detailed description of the invention:
Be further described below in conjunction with the technical scheme of embodiment to patent of the present invention:
Embodiment 1
Patent of the present invention adopts the method for mechanically spraying that anticorrosive paint is sprayed to rebar surface and forms a kind of high-strength and fine and close corrosion protective covering.
First reinforcing bar is tied up by engineering requirement in building site, then the impurity such as dust and greasy filth of rebar surface is cleared up, then steel bar anti-corrosion coating is put in mechanically spraying equipment, the mode of mechanically spraying is adopted to spray from different azimuth rebar surface, guarantee that rebar surface and binding site are wrapped up by anticorrosive paint completely, drain spray phenomenon must not be occurred.
Above-described embodiment, the just one of the preferred detailed description of the invention of patent of the present invention, the usual change that those skilled in the art carry out in patented technology category of the present invention, replaces and all should be included in the protection domain of patent of the present invention.
