Description

Clear-water concrete metope and construction method thereof is watered after the exposed secondary of a kind of peastone
Technical field
The present invention relates to a kind of bare concrete wall, water clear-water concrete metope and construction method thereof more specifically to after the exposed secondary of a kind of peastone, belong to technical field of building construction.
Background technology
Along with the fast development of China's economic construction and the raising of living standards of the people, the functional requirement of people to building wall is more and more higher, except attractive in appearance, durable, also want energy-conserving and environment-protective, with meet people to inhabitation and working environment in aesthetic and that function aspects is higher requirement.
At present, building wall furnishing method is various; But traditional furnishing method, time-consuming, cost is high, not durable, and portion of material also distributes harmful chemical composition, not energy-conserving and environment-protective.Clear-water concrete is also known as ornamental concrete, and it belongs to one-time cast-forming, does not do any external decoration, directly adopts cast-in-situ concretenatural surface effect as facing, be different from ordinary concrete, surfacing is smooth, uniform color, without clashing and breaking and pollution, be just coated with one deck or two-layer transparent protective agent on surface, cast out the chemical products such as coating, facing, be conducive to environmental protection; Again because clear-water concrete one-time cast-forming, do not pick cutter and repair, need not plaster, decrease a large amount of building waste, be conducive to protection of the environment.
Summary of the invention
The object of the invention is to, for traditional building wall furnishing method not energy-conserving and environment-protective, high, the not resistance to problem of waiting so long of cost, after the exposed secondary of a kind of peastone is provided, water clear-water concrete metope and construction method thereof.
For achieving the above object, technical solution of the present invention is: water clear-water concrete metope after the exposed secondary of a kind of peastone, comprise original structure body of wall, also include clear-water concrete surface layer, described clear-water concrete surface layer is built on original structure exterior surface of wall, clear-water concrete surface layer is provided with peastone aggregate, in clear-water concrete surface layer, is provided with steel mesh reinforcement, and be provided with bar planting in clear-water concrete surface layer and original structure body of wall.
Described clear-water concrete surface thickness is 60-80mm.
Water a construction method for clear-water concrete metope after the exposed secondary of peastone, 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, high pressure water flushing wash clean dust and scum silica frost;
Step 2, implantation bar planting: implant bar planting by the technological process of regulation;
Step 3, mount steel mesh reinforcement: take bar planting as rest, mount steel mesh reinforcement;
Step 4, 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, simultaneously inside template to put sticky mode, by predetermined pattern or the fixing peastone aggregate of random arrangement arrangement;
Step 5, peastone aggregate exposure: treat the initial set of clear-water concrete surface layer, and after reaching some strength, stripping, high pressure water washing destroys clear-water concrete surface layer surface laitance, and exposed peastone aggregate, completes construction;
Step 6, maintenance: by Construction technology of fair-faced concrete requirement, by heat and moisture preserving measure maintenance maintenance clear-water concrete surface layer 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 6.
compared with prior art, the invention has the beneficial effects as follows:
1, the exposed bare concrete wall of the peastone in the present invention comprises original structure body of wall and clear-water concrete surface layer, clear-water concrete surface layer is built on original structure exterior surface of wall, clear-water concrete surface layer is provided with in peastone aggregate clear-water concrete surface layer and is provided with steel mesh reinforcement, and be provided with bar planting in clear-water concrete surface 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 decorative effect and the reinforcement and strengthening effect to a certain degree of clear-water concrete, meet user demand.
2, the wall construction method in the present invention, by the process of original structure body of wall, implant bar planting, mount steel mesh reinforcement, formwork supporting plate builds clear-water concrete surface layer, the step such as stripping, peastone aggregate exposure and maintenance, both achieved the clear-water concrete decorative effect of fashion, and green energy conservation wall reconstruction can have been reached again.
Accompanying drawing explanation
fig. 1 waters clear-water concrete metope structural representation after the exposed secondary of peastone in the present invention.
In figure, clear-water concrete surface layer 1, peastone aggregate 2, original structure body of wall 3, steel mesh reinforcement 4, bar planting 5.
Detailed description of the invention
Illustrate that the present invention is described in further detail with detailed description of the invention below in conjunction with accompanying drawing.
See Fig. 1, the exposed bare concrete wall of a kind of peastone, comprises original structure body of wall 3 and clear-water concrete surface layer 1.Described clear-water concrete surface layer 1 is built on original structure body of wall 3 external surface, clear-water concrete surface layer 1 is provided with peastone aggregate 2.Be provided with steel mesh reinforcement 4 in clear-water concrete surface layer 1, and be provided with bar planting 5 in clear-water concrete surface layer 1 and original structure body of wall 3; By bar planting 5, clear-water concrete surface layer 1 is connected anchoring with original structure body of wall 3.
Described clear-water concrete surface layer 1 thickness is 60-80mm.Clear-water concrete surface layer 1 is built by self-compaction pea gravel concreten and is formed, and the strength grade of this self-compaction pea gravel concreten is C20 – C80.
Described steel mesh reinforcement 4 is that 6@200(are two-way), in 6 expression steel mesh reinforcements 4 herein, the diameter of plain steel-bar is that 6mm ,@200(is two-way) represent that in steel mesh reinforcement 4, orthogonal reinforcing bar is 200mm in orthogonal both direction rebar spacing.
