Description
Technical field
The utility model relates to railroad track and expressway construction fields, and in particular to corrosion-resistant steel bar mesh sheet.
Background technique
Reinforced mesh is the common components of railroad track and expressway construction, is used for casting concrete mould, plays skeleton
Supporting role can make track bed stable for a long time, have the function of preventing hollow or blocky disengaging.Traditional reinforced mesh structure
It is general fairly simple, it is reticulated by criss-cross reinforcement welding, such reinforced mesh, which can satisfy, to be generally required, but
It is that Large Construction project is then difficult to meet to require in all directions, for example, the anti-corrosion ability of reinforced mesh is poor, is easy corrosion, and
Welding destroys the surface of reinforcing bar, further results in reinforced mesh surface and is easy corrosion, often prefabricated in advance for mega project
A large amount of reinforced mesh, to corroding when using after long-time storage, reinforced mesh structural strength is reduced, and influences its conduct
The skeletal support of concrete mould acts on.
Utility model content
In view of the deficiency of background technique, there is provided corrosion-resistant steel bar mesh sheet, technologies to be solved to ask for the utility model
Topic is that reinforced mesh corrosion resistance is low in the prior art.
In order to solve the above technical problems, the utility model provides following technical solution:
Corrosion-resistant steel bar mesh sheet, including the reinforcing bar and several longitudinally arranged steel of several lateral arrangements intersected and welded
Muscle, the reinforcing bar peripheral surface are provided with several evenly spaced helical grooves, the reinforcing bar along the reinforcing bar length direction
Periphery coat matcoveredn, the protective layer from inside to outside successively include the first corrosion-inhibiting coating, adhesive layer and the second corrosion-inhibiting coating,
Adhesive layer can use organic bond.
Preferably, first corrosion-inhibiting coating is raw lacquer.
Preferably, first corrosion-inhibiting coating with a thickness of 1.5mm-2.2mm.
Preferably, second corrosion-inhibiting coating is chlorinated polyvinyl chloride paints.
Preferably, second corrosion-inhibiting coating with a thickness of 0.8-1.2mm.
Preferably, the depth and width of the helical groove are 1.1mm-1.5mm.
Possessed beneficial effect is the utility model compared with prior art: it is reasonable in design, it is welded in reinforced mesh
After connecing completion, the first corrosion-inhibiting coating, adhesive layer and the second corrosion-inhibiting coating are successively coated, can make up for it welding to rebar surface
Anti-corrosion ability caused by destroying reduces, and also can be improved the anti-corrosion effect of reinforced mesh script.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the schematic diagram of reinforcing bar described in the utility model；
Fig. 3 is the cross-sectional view of reinforcing bar described in the utility model.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figure 1-3, corrosion-resistant steel bar mesh sheet, including the reinforcing bar 1 of several lateral arrangements that intersects and weld and several
Longitudinally arranged reinforcing bar 1,1 peripheral surface of reinforcing bar are provided with several evenly spaced helical grooves 2 along 1 length direction of reinforcing bar,
1 periphery of reinforcing bar coats matcoveredn 3, and protective layer 3 successively includes that the first corrosion-inhibiting coating 31, adhesive layer 32 and second are anti-from inside to outside
Rotten coating 33, adhesive layer 32 can use organic bond.
Such structure is with various effects: one, helical groove 2 improves the faying face of reinforcing bar 1 Yu concrete,
Therefore the binding force of corrosion-resistant steel bar mesh sheet and concrete is improved；Two, helical groove 2 improves reinforcing bar 1 and protective layer 3
Faying face, therefore the binding force of protective layer 3 and reinforcing bar 1 is improved, corrosion-resistant steel bar mesh sheet can be effectively prevent to stack, carried
Protective layer 3 falls off in journey；Three, helical groove 2 avoids reinforcing bar 1 from causing ratcheting phenomena impair welding machine of mesh in blanking on welding machine of mesh
It works normally；Four, helical groove 2 is easy to process, higher relative to other dent processing efficiencies.
First corrosion-inhibiting coating 31 is raw lacquer, and raw lacquer is cheap, can reduce production cost.
First corrosion-inhibiting coating 31 with a thickness of 1.5mm-2.2mm, coating layer thickness appropriate can take into account cost and anti-corrosion effect.
Second corrosion-inhibiting coating 33 is chlorinated polyvinyl chloride paints, although chlorinated polyvinyl chloride paints price is high to have more excellent performance,
It is suitable as outermost corrosion-inhibiting coating.
Second corrosion-inhibiting coating 33 with a thickness of 0.8-1.2mm, coating layer thickness appropriate can take into account cost and anti-corrosion effect.
The depth and width of the helical groove 2 are 1.1mm-1.5mm, neither destroy the structural strength of reinforcing bar 1,
With certain faying face in conjunction with protective layer 3 and concrete, certain binding force is generated.
The structure design of the utility model is reasonable, after reinforced mesh welding is completed, successively coats the first corrosion-inhibiting coating, glues
Layer and the second corrosion-inhibiting coating are tied, can make up for it anti-corrosion ability caused by the destruction welded to rebar surface reduces, and also can be improved
The anti-corrosion effect of reinforced mesh script.
Above-mentioned foundation the utility model is enlightenment, and through the above description, relevant staff completely can be not
In the range of deviateing this item utility model technical idea, various changes and amendments are carried out.This item utility model it is technical
Range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
