Water a construction method for bare concrete wall after heat preserving type secondary, comprise the following steps:

The process of step one, original structure body of wall: cut the rendering layer of original structure exterior surface of wall, loose hollowing until expose solid fresh basal plane, cleaning dust and scum silica frost, and repair smooth with mending mortar;

Step 2, implantation bar planting: implant bar planting by the technological process of regulation;

Step 3, installation heat preservation sandwich layer: heat insulating material is pasted on treated original structure exterior surface of wall by structure glue;

Step 4, mount steel mesh reinforcement: take bar planting as rest, mount steel mesh reinforcement;

Step 5, formwork supporting plate build clear-water concrete surface layer: by Construction technology of fair-faced concrete, formwork supporting plate, build clear-water concrete surface layer;

Step 6, stripping, complete construction;

Step 7, maintenance: by Construction technology of fair-faced concrete requirement, by heat and moisture preserving measure maintenance clear-water concrete surface layer (1) to design strength.

Step below is also comprised: Xiu Se and protection are carried out to clear-water concrete surface layer surface after described step 7.

compared with prior art, the invention has the beneficial effects as follows:

1, the heat preserving type bare concrete wall in the present invention comprises original structure body of wall, clear-water concrete surface layer and heat preservation sandwich layer, is provided with steel mesh reinforcement in clear-water concrete surface layer, and is provided with bar planting in clear-water concrete surface layer, heat preservation sandwich layer and original structure body of wall.Overcome that traditional building wall furnishing method is time-consuming, cost is high, the defect such as not durable, not energy-conserving and environment-protective, achieve the decorative effect of clear-water concrete; Meanwhile, achieve the heat-insulating property of metope, meet user demand.

2, the wall construction method in the present invention, by the process of original structure body of wall, implant bar planting, heat preservation sandwich layer is installed, mounts steel mesh reinforcement, formwork supporting plate builds the steps such as clear-water concrete surface layer, stripping and maintenance, both achieved the clear-water concrete decorative effect of fashion, and green energy conservation wall reconstruction can have been reached again.
