Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of bracing means with anchor structure and reinforcing
Method.
Background technology
Reinforced concrete structure is topmost structure type in civil engineering, and its security develops in a healthy way with national economy
It is closely related.However, with the increase and the change of use environment of service life, the deterioration of reinforced concrete structure and function are lost
Effect is more universal and serious, causes concern of the scientific research scholar to concrete structure durability problem.In brief, concrete
Durability refers to that concrete resists the effect of various destructive factors under active usage conditions, long-term to keep intensity and complete appearance
The ability of property.
From the perspective of materialogy, the main reason of reinforced concrete structure durability deterioration is the rust of internal reinforcing bar
Erosion, reinforcing bar is studied more ripe in the Corrosion mechanism of inside concrete.At present, concrete is self-contained or chlorine of outside intrusion
Ion is considered as the main reason for causing corrosion of reinforcing steel bar.The means for suppressing steel bar corrosion are a lot, for example, apply anti-corrosion
Layer and corrosion inhibiter etc., wherein impressed current cathodic protection technology has proved to be one of most efficient method, in some cases
Even unique solution.Impressed current cathodic protection technology is put forward based on PH- potential diagram principles, it is believed that passed through
Apply cathode current to reinforcing bar and make reinforcing bar current potential Luo Mianshi areas, and then reach the purpose of protection reinforcing bar, impressed current anode is outer
Plus the important component of current cathodic protection system.
From the perspective of structure design, concrete structure durability deterioration is embodied in the bad of element mechanics performance
Change, utilize steel plate and fiber-reinforced polymer（Fiber Reinforced Polymer, abbreviation FRP, light weight and it is hard, it is non-conductive,
High mechanical strength, is recycled less, corrosion-resistant）Etc. structure enhancing and reinforcement material, it is proposed that increasing section and paste outside etc.
Various structures reinforcement technique, and have application to engineering practice.Structural reinforcing material generally passes through binder materials（Such as epoxy resin）
With concrete structure shared load action, the additional protective layers of concrete structure are can be considered, and completely cutting off outer to a certain degree
Erosion of portion's surrounding medium to internal structure, but reinforcement material during the defect of construction technology and error, structure military service
Deterioration and loss can all destroy this protective layer, cause the anticaustic of concrete structure.Importantly, structural strengthening technology
Inside concrete harmful element can not be solved（Chloride and sulfate in such as sea sand concrete）Continuation to reinforcing bar is corroded,
Existing many structures are reinforced more than once in Practical Project, often occur repairing repeatly bad situation repeatly.
Therefore, generally required in engineering practice while structural strengthening and cathodic protection are carried out, to reach what is treated both principal and secondary aspect of disease
Structure repair and consolidation effect.So far, need to consider alone when most of engineerings are repaired to add structure respectively
Gu and protection, this certainly will cause high financial burden to owner.
In addition, traditional composite plate binder materials to be fixed on by way of pasting in structure, but this mode is not
Only it is difficult to control in paste intensity, and with the erosion of harmful environmental ion, the situation of paste interface deterioration can be more tight
