The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment of the present utility model: structural representation of the present utility model such as Fig. 1～shown in Figure 3.When implementing a kind of non-fine concrete sandwich wall structure of the present utility model, this method comprises employing non-fine concrete preparation method of the prior art and adopts template to carry out the method for cast in situs non-fine concrete body of wall, during construction, architectural design mode routinely is provided with reinforced concrete pillar 3 in non-fine concrete body of wall intersection or corner, at the superstructure 4 that is provided with the cast-in-place plate between floor and the floor on the non-fine concrete body of wall
When adopting non-fine concrete cast in situs non-fine concrete wall construction, earlier template is propped up, thermal-insulation baffle plate 5 is placed in the template, adopt segmentation, the mode of building of layering is built, be that segmentation is built mode for to build the non-fine concrete body of wall by the height of every section 50～150cm from top to bottom, the mode of its placement layer by layer is the non-fine concrete body of wall to be built serve as reasons interior body of wall 1 and outer body of wall 2 and thermal-insulation baffle plate 5 form, and the sandwich wall body structure (as depicted in figs. 1 and 2) in thermal-insulation baffle plate is arranged between body of wall 1 and the outer body of wall 2, interior body of wall 1 can be determined according to actual needs with the thickness of outer body of wall 2, generally speaking, the thickness summation that interior body of wall 1 and outer body of wall 2 can be added again thermal-insulation baffle plate 5 is controlled between 120 millimeters～400 millimeters and gets final product, and use because interior body of wall 1 can be used as load bearing wall, the thickness of therefore interior body of wall 1 under normal conditions should be bigger than the thickness of outer body of wall 2; Then the interior body of wall of non-fine concrete body of wall and outside all cover cement sand bed 6 on the external surface of body of wall, this cement sand bed 6 can directly adopt existing cement mortar to make, and its thermal-insulation baffle plate 5 can adopt board making such as existing XPS plate, EPS plate, heat preservation rock plate or plastic foamboard to form; During construction, for body of wall in making 1 and outer body of wall 2 and thermal-insulation baffle plate 5 connect as one better, can be when whenever having built one section non-fine concrete body of wall, on the aspect of the junction of every section non-fine concrete body of wall, all place a row can with interior body of wall 1 with outside the lacing wire 7 that links together of body of wall 2, it is the reinforcement fabrication of Φ 6～Φ 16 that lacing wire 7 can be adopted diameter, the shape of lacing wire 7 can be made as straight-bar shape, crotch shape or П shape, and will be controlled at the scope of 200～600mm at the spacing distance between per two lacing wires 7 on the same level height; Can realize self-ventilation in order to make outer body of wall 2, to reach effect better heat insulation and protection cement sand bed 6, the lower position of the cement sand bed 6 of body of wall 2 (generally being higher than 20～300cm place, exterior wall skirting top) is produced the air vent 8 that outer body of wall 2 is in communication with the outside outside, the shape of air vent 8 and quantity can be determined arbitrarily according to actual needs, air vent 8 can be made into the air vent that diameter is 1～10cm generally speaking, the quantity of air vent 8 should be no less than 2, and the top of the cement sand bed 6 of body of wall 2 (generally in cement sand bed 6 tops and 20～300cm place, below, uppermost roof panel 15 boundary of outer body of wall 2) produces air-vent 9 outside, by air vent 8 and air-vent 9 part of outer body of wall 2 is communicated with the external world, make whole outer body of wall 2 realize self-ventilation simultaneously; In order to reach better heat insulating effect, during construction, the interior body of wall 1 of non-fine concrete body of wall built with reinforced concrete pillar 3 connect as one, and after superscribing thermal-insulation baffle plate 5 on the lateral surface of reinforced concrete pillar 3, build out the outer body of wall 2 of non-fine concrete body of wall again in the outside of thermal-insulation baffle plate again and produce cement sand bed 6; Simultaneously, after the edge of the superstructure on the body of wall 1 in the non-fine concrete body of wall 4 or end all covered in thermal-insulation baffle plate 5, build out the outer body of wall 2 of non-fine concrete body of wall again in the outside of this thermal-insulation baffle plate 5 and produce cement sand bed 6.
For better utilization solar energy and reach better heat insulating effect, can on above-mentioned air vent 8, all adorn an air inlet pipe 10, on each air-vent 9, all adorn an escape pipe 11; Then every floor in the face of in the east, the bottom of the non-fine concrete body of wall in west or every room in the south installs one～five exhaust column 12, and make exhaust column 12 pass cement sand bed 6 and the interior body of wall 1 and the thermal-insulation baffle plate 5 of interior body of wall 1, make the exterior of the cement sand bed 6 of the inside of outer body of wall 2 and interior body of wall 1, and on the mouth of pipe of each exhaust column, all adorn an induced draft fan 13; When being provided with floor 14 in every room at every floor, preferably the mouth of pipe of exhaust column 12 is arranged on the bottom of the cement sand bed 6 of body of wall 1 in the non-fine concrete body of wall of every floor, and make the air outlet that is installed in the induced draft fan 13 on exhaust column 12 mouths of pipe be lower than in the bottom surface (as shown in Figure 3) on the outer floor 14 of body of wall 1.
When adopting above-mentioned the technical solution of the utility model, non-fine concrete body of wall of the present utility model has extraordinary self-regulated warm nature energy, and its body of wall can be from temperature adjustment.When summer, induced draft fan 13 can cut out, the air outlet of induced draft fan 13 is closed, because the thermal resistance effect of thermal-insulation baffle plate 5, hot-fluid is blocked, in addition " stack effect " effect, heat is carried away through turnover tracheae 11 by air-flow, so just guarantee the indoor extraneous extremely hot influence that is not subjected to, indoor refrigerant, the utility model has improved the comfort level of living in the house with simple and the most natural mode.
When daytime in winter, can be with the power connection of induced draft fan 13, the air outlet of induced draft fan 13 is opened, induced draft fan 13 work, at this moment, the heats that induced draft fan 13 will have been shone in the hot outer body of wall 2 by the sun are drawn into the Stilt layer of floor below 14, because heat can only up transmit, this heat absorbs slowly release of back through the non-fine concrete recuperation layer under the floor 14, guarantee indoor warm, thereby realized body of wall from temperature adjustment.Do not have the solar time when winter, only need be closed induced draft fan 13 and be got final product.
Adopt the house of the utility model design-build, not only have the advantage of good effect of heat insulation, but also have cool warm effect of winter of summer.The utility model has been realized building energy conservation with the mode of environmental protection and economy.
