Abstract
The utility model belongs to the field of buildings and particularly relates to a maintaining design structure of a damaged building. The maintaining design structure comprises a damaged wall, an interface layer and a polyurea coating. The damaged wall is of a damaged concrete structure, colloidal cement mortar or cement putty made by mixing vinyl acetate emulsion is filled in a damaged part in the damaged wall, the interface layer is coated on the damaged wall and is a polyurea special primer layer, and the polyurea coating is sprayed on the interface layer. Main raw materials of the maintaining design structure are inorganic materials, are green and environment-friendly and can be formed by spraying on random curved surfaces, inclined planes and vertical planes, and a construction speed is quick.
Description
Technical field
The utility model belongs to building field, relates in particular to a kind of damaged concrete building and repairs project organization.
Background technology
At present concrete construction is used very extensive, and its basic reason is himself special performance of concrete material, comprises and drawing materials conveniently, low price, the advantage such as speed of application is fast, and quality safety is reliable, and intensity is high, and refractoriness is good.Yet in recent years, the etching problem of concrete construction more and more causes people's concern, and etching problem causes concrete cracking, and corrosion of steel bar destroys then, and intensity reduces greatly, and the safety of structure must not get and ensured.
Summary of the invention
The utility model is for above deficiency, provides a kind of simple in structure, environmental protection, the fast impaired building of speed of application to repair project organization.
The technical scheme that the utility model adopts is:
A kind of impaired building is repaired project organization, comprise impaired body of wall, boundary layer, polyurea coating, impaired body of wall is damage concrete structure, the impaired cement plaster that is partially filled glue cement mortar or acetate emulsion modulation in impaired body of wall, boundary layer is coated on impaired body of wall, boundary layer is polyureas special bottom enamelled coating, spray polyurea coating on boundary layer.
The beneficial effects of the utility model:
Main raw material(s) is inorganic material, environmental protection, can spray mo(u)lding on arbitrary surface, inclined-plane and vertical plane, speed of application is fast, has thoroughly overcome the shortcomings such as ubiquitous solvent contamination in conventional spray paint technique, sagging, hardening time length, complicated construction technique.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure 1, impaired body of wall, 2, boundary layer, 3, polyurea coating.
The specific embodiment
As shown in drawings, a kind of impaired building is repaired project organization, comprise impaired body of wall 1, boundary layer 2, polyurea coating 3, impaired body of wall 1 is damage concrete structure, the impaired cement plaster that is partially filled glue cement mortar or acetate emulsion modulation in impaired body of wall 1, boundary layer 2 is coated on impaired body of wall 1, and boundary layer 2 is polyureas special bottom enamelled coating, spray polyurea coating 3 on boundary layer 2.
When the polyureas technology is repaired damaged concrete building structure, when crack width greater than 0.2mm, first chemical grouting, then polish with sander on the distress in concrete surface, the polishing width is 20cm, and is polished into triangle in the marginal portion at 16cm scope place, and the edge degree of depth is 4mm.So way, safe and reliable, guaranteed reliability and the aesthetic property that repair in the crack;
When polyurea coating 3 unavoidably will interrupt in the middle of basic unit, by dig out the V-notch of 8mm in basic unit, the polyurea coating 3 of constructing again, dispose and face antermarginal unnecessary coating, make the smooth and cleaning in whole construction plane, receive a quality at place and be guaranteed, the hidden danger of quality of receiving head has been eradicated in the specially treated of V-notch.
Claims (1)
1. an impaired building is repaired project organization, comprise impaired body of wall, boundary layer, polyurea coating, it is characterized in that: impaired body of wall is damage concrete structure, the impaired cement plaster that is partially filled glue cement mortar or acetate emulsion modulation in impaired body of wall, boundary layer is coated on impaired body of wall, boundary layer is polyureas special bottom enamelled coating, spray polyurea coating on boundary layer.
