Description

Composite insulation boards

The utility model belongs to building material field.

Worker, China Democratic National Construction Association build insulation at present, a large amount of traditional cladding and structures of using, as: the temperature that adds that the roofing heat preservation and insulation layer adopts coagulates soil block, perlite soil block or the poly-stupid vinyl foam plate of direct tiling; Magnalium making sheet, gypsum plank etc. are adopted in outer strong interior insulation.Its weak point is, thermal transmittance is higher, and it is numerous and diverse, long in time limit to construct, and quality is difficult for guaranteeing that particularly easy to leak, and application scenario also has certain limitation.

The object of the present invention is to provide a kind of composite insulation boards, structure set layer, insulation layer, surface layer have high heat insulating ability, light weight, high strength in one, and manufacture technology is easy, use easy construction, and the duration is short, and quality is guaranteed, and be simultaneously applied widely.

Concrete scheme is: composite insulation boards, be divided into four classes substantially by function, and the first kind is a heat insulating board for roofing, generally as heat-insulation and heat-preservation (see figure 1) on the roof hollow floor; Second class is the panels with interior insulating layer for external wall (see figure 2); The 3rd class is the large insulation deck panels, generally is exclusively used in the bigger building of span, and holding concurrently as roof slab is incubated, and is used for wallboard or partition board (see figure 2); The 4th class is the Outwall thermal insulation board (see figure 2).

Fig. 1, single face layer composite insulation boards; Fig. 2, two-sided layer composite insulation boards.

Structural group becomes: heat-insulation layer 1, enhancing grid cloth 2, cementing agent layer 3, surface layer 4; The cementing agent layer 5, strengthen grid cloth 6, screed-coat 7. Heat-insulation layer 1 selects light weight that the fire-retardant guarantor of whole solid shape is arranged The adiabator plate, as: the polystyrene plastic foamboard; Strengthen grid cloth 2 and 6, anti-flammability soft, hard Material all can, such as glass fiber mesh;

Cementing agent layer

3 and 5 is selected powerful height, has and phase The fine intermiscibility of pass material, as: vinyl acetate one ethene co-falling emulsion; Surface layer 4, screed-coat 7 For the high-strength concrete layer, select 525^#Cement.

Above-mentioned four kinds of its differences of warming plate are, because use location and function are not quite similar, thereby protect Temperature layer material thickness strengthens the grid cloth width of mesh, bulk strength and surface layer or screed-coat thick Spend differently with intensity, as for the warming plate geometric specifications, the assembling pattern is by the building size requirement and make Do, easy construction is the principle designed, designed, producing in serial form, the special-shaped available Shi Jiren that weeds in district in the construction Meaning is cut out as required and is cut. For two-sided layer composite insulation boards, inside in line with screed-coat 7 during construction, surface layer 4 Outside principle, splicing is installed.

Manufacture technology:

For single face layer composite insulation boards, behind the formwork of level land, earlier specification ground adiabator plate is put into mould, brush adhesive material then in the above, repave the enhancing grid cloth, squeeze into the high-strength concrete surface layer at last, floating, treat demoulding after, natural curing gets final product.

For two-sided layer composite insulation boards, behind the Zhi Heng of level land, the high-strength concrete of shop one deck specific thickness is as leveling layer earlier, after floating, spread the enhancing grid cloth, will simultaneously brush the adiabator plate of adhesive material, glue faces down and is placed on the grid cloth, the one side that adiabator plate is made progress brushes adhesive material again, repave the enhancing grid cloth, squeeze into the high-strength concrete surface layer at last, floating, after treating demoulding, natural curing gets final product.

Usefulness of the present utility model is: structure set layer, insulation layer, surface layer are one, have high insulation, light weight, high-intensity characteristics, have good deadening concurrently, manufacture technology is easy, uses easy construction, reliable in quality, compared with the prior art, durable in use, save cement, reduction of erection time, cost does not increase yet, and material source extensively is easy to get, and is applied widely.

Embodiment: unit: millimeter.

Insulation layer 1 is selected poly-stupid vinylic foam plate for use, strengthens grid cloth 2 and 6 and selects fiberglass gridding cloth for use, and

adhesive material layer

3 and 5 is selected vinyl acetate-ethylene copolymerization emulsions for use, surface layer 4 and leveling layer 7 usefulness 525 ^#The cement preparation.

The first, the aspect heat insulating board: 850 * 600 * 60, insulation bed thickness 50, after roof is looked for the slope, can assembly unit lay this plate, after seam is drawn with the polyurethane foam processing in the scene, need not cement mortar screeding,, facts have proved when doing waterproofing work, save cement 2/3 with the conventional art ratio, every square metre of saving of labor 2/3,8～10 days durations are indeformable in advance, non-leakage, all can construct easily summer in winter.

Second, panels with interior insulating layer for external wall: 2700 * 600 * 45, the insulation bed thickness 25, surface layer and leveling layer each thick 10, after interior wall is smooth, divide equally horizontal floating screed four roads by the metope height, wide by 60, high by 20, on floating screed, scrape 107 glairin cement paste tack coats, afterwards this plate leveling layer is attached on the floating screed to metope, upper and lower wedging, the overlap joint perps sticks on plate with 50 wide glass fiber cloth and sews on, and cement mortar is wipeed off and is got final product.

The 3rd, the large insulation deck panels: 3000 * 1200 * 110, insulation bed thickness 100, each is thick 5 for surface layer and leveling layer, is used for the large span industrial premises, ball-type rack aspect, wallboard, partition board, light weight (30kg/ rice ²), can solve the disadvantage of the fertile beam of traditional design, fat post, deep foundation, save a large amount of human and material resources.Lay or install, after cement mortar or polyurethane foam joint filling, need not cement mortar screeding, can on surface layer, do waterproofing work thereupon,, can directly do interior decoration body of wall.

The 4th, Outwall thermal insulation board: 400 * 400 * 38, insulation bed thickness 30, surface layer is former 5, levelling bed thickness 3, after exterior wall was smooth, roughly the same tile fixing equally directly was attached to wall and adds, and smears seam with cement.

The warming plate physicochemical property all can meet or exceed national regulation, as, aspect heat insulating board thermal resistance 1.22m ²K/W, every meter horizontal fracture resistence force forward 1200N/m, reverse 350N/m, high pressure concrete compressive strength 28.2N/mm ²Panels with interior insulating layer for external wall thermal resistance 0.625m ²K/m, fracture resistence force forward 780N/m, oppositely 730N/m.
