Preferably, glue is that mass ratio is 1 in step S4：0.2 water is constituted with Environment-friendlyglue glue.
Wherein, the whiteness of described white cement is more than 87 degree, and lime paste is used after curing.
After using above technical scheme, the invention has the advantages that：
1. extra large oyster shell is original ecological material, and shadow rich color, art of wall is strong, and in coastal area, materials are easy, valency
Lattice are cheap, and discarded extra large oyster shell is reused, environmental and ecological.
2. compared with conventional outer wall material, extra large oyster shell decoration wall has significant heat insulation and acoustic absorption effect, low cost, later stage
Easy to maintenance, weatherability, durability are strong.Compared with the oyster shell wall of traditional engineering method sea, using small size sea oyster shell as raw material, material
It is lightweight, improve the security of skyscraper utilization.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is heat-flow meter method test philosophy schematic diagram.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.
As shown in figure 1, the invention discloses a kind of extra large oyster shell veneer exterior, including from the interior porous brick wall 1 for arranging outward,
Screed-coat 2, white cement tack coat 3 and extra large oyster shell finish coat 4, extra large oyster shell finish coat 4 by a large amount of extra large oyster shells facing away from outer, back-off one by one
It is pressed against arrangement form on white cement tack coat.Extra large oyster shell finish coat 4 of the invention selects small size sea oyster shell as raw material,
Size range is：The ellipse sea oyster of 55mm ~ 85mm long, 30mm ~ 40mm wide, material weight is light, can be used for skyscraper.
The invention also discloses the construction method of extra large oyster shell veneer exterior, comprise the following steps：
S1. extra large oyster shell raw material are selected, extra large oyster shell carries on the back unnecessary shell and debris through artificial shell of rejecting, the hull shape selected should be compared with
For uniform color meets design requirement, and should be dried placement nature after two times freshwater soakings and the flushing of artificial outwash.
S2. porous brick wall 1 is built by laying bricks or stones, and slurry plucking is got rid of in top layer cleaning, and mixing Environment-friendlyglue glue using cement mortar is injected in porous brick
On wall surface, and continuously water seasoning more than 3 days；Cement mortar therein is mass ratio 1：1 cement is constituted with fine sand.
S3. it is the screed-coat 2 of 20 ~ 50mm, the surface galling of screed-coat 2 to use Waterproof sand to grout thickness outside porous brick wall 1
Scrape thick；Waterproof mortar be following mass ratio into being grouped into, cement：Fine sand：Waterproof powder=1：2：0.05, the water ash of waterproof mortar
Than being 0.37~0.4.
S4. white cement tack coat 3 is built by laying bricks or stones, and it is glue to use mass ratio：White cement：Lime paste=0.4：1：0.2 into
Distribution is set to white cement cream, and white cement cream is built into outer to the cement mortar screeding layer of step S3, and thickness is 10 ~ 30 mm.Glue is
Mass ratio is 1：0.2 water is constituted with Environment-friendlyglue glue.The whiteness of white cement should be greater than 87 degree, and lime paste is used after curing.
S5. extra large oyster shell finish coat 4 is built by laying bricks or stones, and the extra large oyster shell shell that step S1 is dried is pressed in white cement and glues facing away from connecing one by one outward
On knot layer 3 so that the outer rim insertion tack coat 3 of extra large oyster shell is no less than 5mm, and extra large oyster shell is adjacent not to be stacked, and facing completely spreads；
S6. the unnecessary slurry of white cement tack coat 3 of extra large oyster shell periphery extrusion is cleared up, secondary returning is carried out to extra large oyster shell finish coat
Pressure；
S7. extra large oyster shell paving is sprinkled water after 24 hours and is conserved, and curing time is no less than 3 days.
Due to industry standard limitation, exterior wall mosaic cannot be used for high-rise with building exterior wall material, traditional oyster shell wall by
It is too heavy in weight, low layer is only used for, extra large oyster shell is light due to its material weight, and rationally, the characteristic such as low energy consumption can be used for height to cost
Layer building, and its shadow rich color, art of wall are strong.Compared with conventional outer wall material, extra large oyster shell faced wall of the invention
Body has significant heat insulation and acoustic absorption effect, it is possible to decrease building energy consumption.It is below one group of experimental demonstration：
Extra large oyster shell veneer exterior heat transfer coefficient on-site test
First, test philosophy
Heat-flow meter method Cleaning Principle is that the temperature difference using wall surfaces externally and internally and the heat flow by wall carry out heat transfer system
Several measure, its basic theories is built upon on the basis of Fourier law, it is believed that wall is in one-dimensional steady-state heat transfer process, profit
The inside and outside wall surface temperature of wall is measured with heat-flow meter, the thermal conduction resistance and heat transfer coefficient of tested wall is calculated further according to formula, such as
Fig. 2 shows.
2nd, testing procedure
1st, tester：It is -200~350 DEG C of T-shaped thermocouples from test scope, and before testing by laboratory mark
Fixed, temperature is simultaneously set 15 DEG C by indoor placement cabinet air-conditioner, so that indoor thermal field is uniform.
2nd, point layout：3 groups of measuring points of arrangement are concordantly corresponded in the outer surface of extra large oyster shell veneer exterior and inner surface.
3rd, test process：Heat flow transducer data acquisition is arranged by wall surfaces externally and internally, appearance in wall is determined
The hot-fluid in face, the heat transfer coefficient for calculating tested wall finally according to formula is 1.12W/ (m.K).
4th, conclusion：By above experiment test, the heat preservation and insulation of extra large oyster shell veneer exterior of the invention is good, the winter
The warm summer is cool.Because extra large oyster shell is light, can be used for skyscraper；Its stagger arrangement is piled up, and with shaded effects, can reduce surface to the sun
The absorption of radiant heat；Natural rainfall being stored simultaneously, passive water vaporizing and cooling is formed, weatherability, durability being strong, suitable popularization should
With.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in,
Should all be included within the scope of the present invention.
