Detailed description of the invention
Embodiment one
The little temperature difference heat-preserving wall of one of the present embodiment, comprises body of wall 5 as shown in Figure 1 and is fixedly mounted on the warming plate 13 outside body of wall 5 by reinforcing bar 6; Warming plate 13 is shaped with projection 7 spaced apart towards the side of body of wall 5; At least one in projection 7 is shaped with the first through hole 14, body of wall 5 is shaped with the blind hole 15 of corresponding first through hole 14; Reinforcing bar 6 inserts in blind hole 15 through the first through hole 14; Reinforcing bar 6 and first leads to filling concrete based adhesive 12 between 14 and hole blind 15, and then forms steel concrete outrigger; Be formed with air flue 8 between warming plate 13 and body of wall 5, be provided with the air inlet port 10 of air flue 8 bottom body of wall 5, the top of body of wall 5 is provided with the gas outlet 9 of air flue 8.
The warming plate 13 used in the present embodiment need make in advance, use expanded perlite is suppressed, by the shape that the shape constraining of mould is as Fig. 2, the side of warming plate 13 has the cylindrical projections 7 of uniform intervals distribution, projection 7 exceeds the surperficial 10mm of warming plate 13, after wall construction completes, namely the width of air flue 8 approximates the height of projection 7.
Warming plate in the present embodiment also can use cement, slag or granular polystyrene to suppress and form, and its effect and the present embodiment there is no essential difference.
During construction, at body of wall 5 appearance millet cake paving cementing agent, general use cement, the projection 7 of prefabricated warming plate 13 is imbedded in cementing agent, warming plate 13 can be fixed on the corresponding position of body of wall 5, then a projection 7 on this warming plate 13 is selected, the first through hole 14 is made a call to body of wall 5 direction at warming plate 13 from this projection 7, first through-hole diameter 14 is less than the diameter of projection 7, be greater than the diameter of reinforcing bar 6, after warming plate 13 is got through, continue to squeeze into the dark blind hole of about 50mm 15 in body of wall 5, then cement mixing fine sand is injected as adhesive 12, then the indented bars 6 of Φ 5 or more is used, cut into length just can extend to the external surface of warming plate 13 section from the bottom of blind hole 15 in advance, then insert in blind hole 15 through the first through hole 14, solidify to form steel concrete outrigger for be bonded dose 12, namely the construction of the little temperature difference heat-preserving wall of the present embodiment is completed.
After having constructed, the bottom of body of wall 5 is located at by the air inlet port 10 of air flue 8, if the house of construction has basement, is then located in basement.Meanwhile, in order to prevent sleet etc. from entering air flue 8, under the gas outlet 9 of air flue 8 is located at eaves, or set up the cover plate that keeps off the rain.
Air flue 8 has been communicated with top and the bottom formation stack effect of body of wall 5, simultaneously, if house has basement, then the temperature of basement is more constant, cool in summer and warm in winter, utilize the gas of basement to flow through air flue 8, complete heat radiation, dehumidifier in summer, can also lower the temperature for body of wall while eliminating the temperature difference, winter is then just for heating up for body of wall.
Embodiment two
The present embodiment improves on the basis of embodiment one, its major part is identical, different piece as shown in Figure 3 and Figure 4, wherein shown in Fig. 3: install power-assisted blower fan 11 additional at air inlet port 10 place of the little temperature difference heat-preserving wall of the present embodiment, better can promote that the gas in air flue 8 flows, to reach better heat insulation effect like this.
For reaching further heat insulation effect, as shown in Figure 4, the warming plate 13 used in the present embodiment is a kind of prefabricated composite insulation boards.Warming plate 13 is made up of the organic material insulation layer 1 be combined with each other and inorganic material insulation layer 3; Organic material insulation layer 1 is provided with the second through hole 4 of uniform intervals distribution; Inorganic material insulation layer 3 is formed by the repressed side at organic material insulation layer 1 of inorganic heat insulation material, and inorganic heat insulation material tamps and passes the second through hole 4 and forms projection 7 at the opposite side of organic material insulation layer 1.
Before construction, need precast heated board 13.The organic material insulation layer 1 of the present embodiment uses polystyrene thermal insulation plate material, first, organic material insulation layer 1 is offered cylindrical second through hole 4, then lies in a horizontal plane on prefabricated mould by organic material insulation layer 1; Then, with cement based glass bead for primary raw material, add the inorganic heat insulation material that appropriate Admixture cellulose ether is obtained, inserting the second through hole 4 and evenly applying paving is sprinkled upon on organic material insulation layer 1, is covered with glass fiber reticular cloth 2 in order to gain in strength in the middle of the inorganic material layer 3 in organic material insulation layer 1 side; Finally, with through pressure, the machine that shakes compacting, inorganic heat insulation material tamps the second through hole 4 and through this hole, due to the profile design of prefabricated mould, can form cylindrical projections 7 in the another side of organic material insulation layer 1, projection 7 higher than the surperficial 25mm of warming plate 13.So just complete the prefabricated of warming plate 13.
Embodiment three
The present embodiment improves on the basis of embodiment one, its major part is identical, different piece as shown in Figure 5 and Figure 6, wherein shown in Fig. 5: add airflow regulating valves 17 at air inlet port 10 place of the little temperature difference heat-preserving wall of the present embodiment, like this can gas flow in the air flue 8 of manual adjustment, to reach better, more energy-conservation heat insulation effect.
For reaching further heat insulation effect, as shown in Figure 6, the warming plate 13 used in the present embodiment is a kind of prefabricated composite insulation boards.Warming plate 13 is made up of the organic material insulation layer 1 be combined with each other and inorganic material insulation layer 3; Organic material insulation layer 1 is provided with the second through hole 4 of uniform intervals distribution; Inorganic material insulation layer 3 is formed by the repressed both sides at organic material insulation layer 1 of inorganic heat insulation material, and inorganic heat insulation material passes and tamps the second through hole 4 and forms projection 7 in the side of warming plate 13.
Before construction, first need precast heated board 13.Add man-hour, the organic material insulation layer 1 of the present embodiment uses polystyrene thermal insulation plate material, first, organic material insulation layer 1 is offered cylindrical second through hole 4, then organic material insulation layer 1 is lain in a horizontal plane on prefabricated mould, have coating paving in advance to spill in prefabricated mould with cement based glass bead for primary raw material, add the inorganic heat insulation material that appropriate Admixture latex powder is obtained; Then, use inorganic heat insulation material, insert the second through hole 4 and evenly coating paving is sprinkled upon on organic material insulation layer 1, in the middle of the inorganic material layer 3 of the opposite side formed in projection 7, be covered with steel fabric sheet 16 in order to gain in strength; Finally, with through pressure, the machine that shakes compacting, inorganic heat insulation material tamps the second through hole 4 and through this hole, due to the profile design of prefabricated mould, can form cylindrical projections 7 in a side of warming plate 13, projection 7 higher than the surperficial 60mm of warming plate 13.So just complete the prefabricated of warming plate 13.
Little temperature difference house insulation body of wall of the present invention is not limited to the concrete technical scheme described in above-described embodiment, and all employings are equal to the technical scheme of replacing and being formed, and are the protection domain of application claims.
