Abstract

The invention discloses a kind of building bar exposed anti-corrosion means of defences in short term, include the following steps:Prepare cement mortar, exposed steel bar pretreatment, brushing, destarch, waste disposal;Generally, the present invention, which has, can effectively prevent exposed reinforcing bar that corrosion occurs in a short time, the advantages of promoting the construction quality of agent structure and the protective layer in later stage can be convenient for go division operation.

Description

A kind of building bar exposed anti-corrosion means of defence in short term
Technical field
The invention belongs to technical field of building construction, and more particularly to a kind of building bar, exposed anti-corrosion is protected in short term Method.
Background technology
Under normal conditions, during use, agent structure reinforcing bar has all directly been covered by concrete building, There is no directly exposed situations.But in actual architecture construction building course, then inherently because by a variety of Part limits, and portion body structure reinforcing bars occur must be in certain short period(1~6 month or so)Exposed situation; At this point, how to effectively prevent the reinforcing bar of exposed parts corrosion occur, at special the asking that will influence the permanent quality of agent structure Topic.Being reached using a kind of method of hermetic type plain-water slurry of brushing effectively prevent exposed reinforcing bar that corrosion occurs in a short time.
Invention content
The purpose of the present invention is to provide a kind of exposed steel bar anti-corrosion means of defence for building, the anti-corrosion means of defences It effectively prevent exposed reinforcing bar that corrosion occurs in a short time, avoids the construction quality for influencing agent structure, and the later stage can be convenient for Protective layer go division operation, have high use value.
The object of the present invention is achieved like this:A kind of building bar exposed anti-corrosion means of defence in short term, including with Lower step:
(1)Prepare cement mortar:The cement mortar of preparation is hermetic type plain-water slurry, and the hermetic type cement mortar configures material and each Ingredients weight parts are as follows:
32.5 grades of 10 parts of Portland cements
8 ~ 12 parts of polymer cement mortar waterproof latex
11 ~ 12 parts of common drinking water
Amount of preparation is according to actually required, with with should be in one hour using finishing with, cement slurry after preparation;
(2)Exposed steel bar pre-processes:If observation reinforcing bar exposed part, which has, gets rusty or speckles with dust and other impurities, with emery cloth or sand Wheel exposed steel bar position is wiped, cleaning of polishing;
(3)It brushes:It takes(1)In prepared cement mortar, pretreated rebar surface is uniformly brushed using half wiper, And it conserves to before subsequent construction operation formally progress;
(4)Destarch:Before subsequent construction operation formally carries out, destarch processing need to be carried out to the cement mortar of antirust treatment, using applying Work scene waste material reinforcing rod or carpenter's hand hammer directly tap rebar surface, by the vibrations generated to reinforcing bar, make completely hard The cement mortar changed falls off naturally at shelly-shaped fragment;
(5)Waste disposal:The shelly-shaped fragment of cement mortar collected and fallen off is cleaned, the tabia or soil cement of indoor backfill are admixed in dispersion In material, amount of powder shape inorganic solid-state particle is served as;Or dispersion is admixed in roofing cement expanded pearlite insulating layer, and part is replaced Fine aggregate particle.
The hermetic type cement mortar configuration material and each component parts by weight are as follows:
32.5 grades of 10 parts of Portland cements
10 parts of polymer cement mortar waterproof latex
11.5 parts of common drinking water.
The step(3)Middle maintenance method is to spray common drinking water to cement mortar surface every 12 hours, and conserve Time is 5 ~ 7 days.
The beneficial effect comprise that:When the antirusting method for the exposed steel bar that the present invention designs, by outside The method for revealing one layer of hermetic type plain-water slurry of external coating of reinforcing bar effectively prevent exposed steel bar surface that corrosion occurs.Second is that this Invention taps the side of rebar surface using waste material reinforcing rod or carpenter's hand hammer in carrying out desizing process to exposed rebar surface Formula, destarch effect is good, and does not damage reinforcing bar.Third, the cement mortar shell fragment that the present invention will fall off, indoor backfill is admixed in dispersion Tabia or cement earth material in, serve as amount of powder shape inorganic solid-state particle;Or roofing cement expanded perlite is admixed in dispersion In insulating layer, replaces part fine aggregate particle, achieve the purpose that turn waste into wealth, saved construction material.
Specific implementation mode
With reference to embodiment to the embodiment of the present invention further instruction.
Embodiment 1
A kind of building bar exposed anti-corrosion means of defence in short term, includes the following steps:
(1)Prepare cement mortar:The cement mortar of preparation is hermetic type plain-water slurry, and the hermetic type cement mortar configures material and each Ingredients weight parts are as follows:
32.5 grades of 10 parts of Portland cements
10 parts of polymer cement mortar waterproof latex
11.5 parts of common drinking water
Amount of preparation is according to actually required, with with should be in one hour using finishing with, cement slurry after preparation;
(2)Exposed steel bar pre-processes:If observation reinforcing bar exposed part, which has, gets rusty or speckles with dust and other impurities, with emery cloth or sand Wheel exposed steel bar position is wiped, cleaning of polishing;
(3)It brushes:It takes(1)In prepared cement mortar, pretreated rebar surface is uniformly brushed using half wiper, And it conserves to before subsequent construction operation formally progress;
(4)Destarch:Before subsequent construction operation formally carries out, destarch processing need to be carried out to the cement mortar of antirust treatment, using applying Work scene waste material reinforcing rod or carpenter's hand hammer directly tap rebar surface, by the vibrations generated to reinforcing bar, make completely hard The cement mortar changed falls off naturally at shelly-shaped fragment;
(5)Waste disposal:The shelly-shaped fragment of cement mortar collected and fallen off is cleaned, the tabia or soil cement of indoor backfill are admixed in dispersion In material, amount of powder shape inorganic solid-state particle is served as;Or dispersion is admixed in roofing cement expanded pearlite insulating layer, and part is replaced Fine aggregate particle.
The step(3)Middle maintenance method is to spray common drinking water to cement mortar surface every 12 hours, and conserve Time is 7 days.
Generally, the present invention, which has, can effectively prevent exposed reinforcing bar that corrosion occurs in a short time, promote agent structure Construction quality and protective layer go division operation the advantages of in later stage can be convenient for.
