Than the shortcoming and defect of prior art, the utlity model has following beneficial effect: the utility model is simple in structure, build easily; The utility model can effectively be recycled rainwater, and collected rainwater does not need special processing can reach living water use water quality standard; The utility model can be to building top under hot weather the heat insulation and heat control of carrying out, remarkably productive.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As illustrated in fig. 1 and 2, Fig. 1 be the utility model save water and energy building one embodiment cross section structure schematic diagram; Fig. 2 is the structure for amplifying schematic diagram of A part in Fig. 1.
A kind of building of saving water and energy, comprises main body building 1, also comprises water receiving tank 2, water receiving pipe 3 and reservoir 4; The roof of described building 1 is provided with isolation layer 5, and described isolation layer 5 comprises upper strata 51, lower floor 52; Upper strata 51 is for laying and form with the haydites of book structure concrete with seepage of water, lower floor 52 is the thin-film material by waterproof or constructional materials laying, upper strata 51, and lower floor 52 between be provided with space, in addition, between lower floor 52 and roof plane, be an angle or be down " V " font;
Each edge on described upper strata 51 stretches out and is eaves shape from building 1 each wall limit; Within each edge of described lower floor 52 is positioned at roof cross section, and described lower floor 52 is provided with opening up water receiving tank 2 under highly minimum edge, the water outlet of described water receiving tank 2 is in water receiving pipe 3 docking, and described water receiving pipe 3 is connected with the reservoir 4 of building bottom.
In the utility model embodiment; the material of haydites of book structure concrete for being mixed with by haydites of book structure and concrete; this concrete not only has good heat insulating effect; and due to the loose structure of haydites of book structure; make this concrete also possess good permeability performance and water purification performance; and be widely used in green building; in the utility model embodiment; more specifically, to select porosity be that 20~30%, 28 days compressive strength is the product that 24~35MPa and coefficient of permeability are 0.1~5mm/s to this haydites of book structure concrete.
For example, application number: " 201310461053.9 ", name are called: " a kind of high-performance environment-friendly water-permeable brick and preparation method thereof " disclosed a kind of porous base course, be to take the layer of concrete that slag and mud haydites of book structure be aggregate, porous base course is composed of the following components by mass: slag: 60-66 part; Mud haydites of book structure: 8-12 part; Cement: 16-22 part.This water-permeable brick, utilizing slag and mud shale is raw material, has advantage with low cost, environment friendly and pollution-free; Prepared water-permeable brick excellent combination property, its intensity level can reach 35MPa, and coefficient of permeability can reach 1.0 * 10
-2cm/s;
As a kind of replacement scheme, in the utility model embodiment, the haydites of book structure concrete on upper strata 51 also can directly substitute by the mode of laying one deck haydites of book structure, between each haydites of book structure, by sneaking into, necessarily has close-burning material formation integral body.
In the utility model embodiment, more specifically, 51Ge edge, upper strata is provided with closed waterwall 6, and described waterwall 6 is provided with drain hole 7, and described drain hole 7 exceeds 1~2cm apart from the vertical height on upper strata 51 than upper strata 51 peaks.More specifically, upper strata 51 and roof plane parallel, or between described upper strata 51 and roof plane, be one and be not more than the angle of 8 °, or described upper strata 51 be down " V " font and and roof plane between angle be not more than 8 °.More specifically, the thickness on described upper strata 51 is 6~10mm, and the width in the space between upper strata 51Yu lower floor 52 is 0.2~0.5mm.
In actual application of the present utility model; rainy day; rainwater is fallen behind upper strata 51; part rainwater is directly discharged to underground from edge; part rainwater can be penetrated into lower floor 52 by haydites of book structure concrete in addition; especially arrange after waterwall 6; there is more rain penetration to lower floor 52; the water purification effect having due to haydites of book structure; the water quality that is penetrated into lower floor 52 reaches living water use standard; the water oozing under these is collected by water receiving tank 2, and is transported in reservoir 4 by water receiving pipe 3, effectively using water wisely.In fine day, summer especially, the good effect of heat insulation itself having due to haydites of book structure concrete; can effectively avoid attic overheated; in addition, due to haydites of book structure concrete is placed on after the rainy day between its space can also storage area moisture, cooling-down effect is better.If be exposed to the sun for a long time in situation, also can, by the rainwater of former storage being back to upper strata 51 and allowing haydites of book structure concrete absorb, reach heat insulation object.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
