Abstract
The utility model relates to a double foam heat insulation composite plate for building roofing, which is characterized in that the double foam heat insulation composite plate for building roofing is composed of a foam plastic bottom board 2 and a foam concrete coating layer 1. The bottom board is provided with the blind hole 3, and the circumference is provided with the enclosing edge 4. The double foam heat insulation composite plate with thick gradient series is made of the double foam heat insulation composite plate which the utility model provides and is laid on the roof surface orderly and forms the slope which the roof surface needs. After seaming and leveling surface treatment, the thermal insulation layer and the sloping layer are formed. Thus, the utility model has the functions of thermal insulation and roof sloping.
Description
Technical field:
The utility model belongs to building materials field, and what particularly relate to a kind of building roof has roof heat insulation, heat insulation, the binary foam composite insulation board of looking for slope and water-proof function concurrently.
Technical background:
Roof heat insulation, heat insulation, to look for the techonosphere on slope generally be construction in layer, light thermal-insulation constructional materials at present commonly used mainly contains two classes.One, inorganic material class: heat insulating materials such as cement expanded perlite, haydite concrete, slag, mortar concrete; generally be to adopt the cast-in-site construction to finish; so method has the shortcoming that the wet trade amount is big, water absorption rate is high, the cycle is long, efficient is low, easily produce cold and hot bridge; the heat-insulating property instability, and understand hollowing, cracking, destruction roof waterproof layer.Two, organic material class: heat insulating materials such as cystosepiment, polyurethane foam are moulded in polystyrene (EPS) extruded sheet, pre-heating, though this class material coefficient of thermal conductivity is lower, the application technology applicable surface is narrower.Because China's north and south temperature difference is bigger, the north heavily is incubated, south is heavy heat insulation, and adopting a kind of monomer material all can not satisfy roofing should the heat insulation technical requirements of insulation again.Some new roofing heat insulating materials have appearred in the building materials market in recent years, as foamed plastics and the compound warming plate of conventional cement mortar, be the weighted cement hardened layer compound in order to increase timber intensity, this type of material heat preservation and insulation is relatively poor, weight is heavier, and cost is also higher.
Summary of the invention:
The purpose of this utility model is exactly a kind of binary foam composite insulation board that is used for building roof that proposes at the deficiency that exists in the prior art.
In order to realize purpose of the present invention, the technical scheme that is adopted is:
A kind of binary foam composite insulation board that is used for building roof is characterized in that it is that composite foam concrete sclerosis covering layer is formed on the foamed plastics base plate.In order to increase the bond strength of foam concrete covering layer and foamed plastics base plate, described foamed plastics back-plane design is the matrix substrate, is provided with the surrounding edge of sealing around it, forms the matrix chamber of sealing; Or be provided with surrounding edge on the corresponding both sides of foamed plastics base plate, form open matrix chamber.The base plate in matrix chamber is provided with blind hole or convex-concave structure, and surrounding edge is provided with groove, is cast with foam concrete in matrix chamber and blind hole or the convex-concave structure, the muscle post that the foam concrete in blind hole or the convex-concave structure forms.The thickness of foamed plastics base plate and surrounding edge and be 50-400mm.The tectal thickness of foamed plastics base plate and foam concrete and be 50-400mm in the absence of surrounding edge.In order to make full use of the binary foam composite insulation board that the utility model provides, in described thickness range (50-400mm), make the binary foam composite insulation board of a plurality of different-thickness (pressing equal thickness difference or non-equal difference) by the binary foam composite insulation board that the utility model provides, they form the gradient series on a piece ladder slope, described binary foam composite insulation board is layed in roofing by above-mentioned requirements constitutes slope, a species stage, handle through seam, levelling, realized roof heat insulation, heat insulation, look for the techonosphere of slope, waterproof.
Because the utility model has adopted the complex of organic flexible layer of foam concrete inorganic rigid layer and foamed plastics matrix substrate, not only having satisfied roofing should the heat insulation technical requirements of insulation again, and have roof slope making, water-proof function concurrently, improved the total quality of roof structure layer, reduced the engineering comprehensive cost, done operation for batch production, standardization and construction the good energy-conservation product is provided.
The specific embodiment:
Description of drawings:
Fig. 1 is the main sectional view of the utility model basic model;
Fig. 2 is that basic model shown in Figure 1 increases the blind hole front view.
Fig. 3 is the front view that increases surrounding edge on the basis of Fig. 2.
Fig. 4 is the binary foam composite insulation board that the utility model is made different-thickness, by the ladder slope schematic diagram of equal difference gradient series formation.
Embodiment 1:
As shown in Figure 1, the utility model basic model adopts fire retardant polystyrene EPS particle, through send out in advance, the foamed plastics base plate 2 of thermoplastic compression molding, the density of base plate 2 is 15-30kg/m
3, the porosity more than 95%, coefficient of thermal conductivity w/ (m*K) 0.035-0.038, water absorption rate 0.5-1.5%, every cubic decimeter of volume contains 300-600 ten thousand independent closed polyhedron bubbles, and contain air is more than 98%.The hardened layer of compound on the foamed plastics base plate 2 (cast) one deck foam concrete is as covering layer, and the density of foam concrete is 300-1200kg/m
3, can reach microporosity more than 70%, coefficient of thermal conductivity w/ (m*K) O.12-0.26.Foam concrete directly is poured on the foamed plastics base plate 2 by the slurry that portland cement (also can adopt air-hardening cement), flyash, JT blowing agent, fluidizer are prepared into, by folded mould, plastotype, aquation, maintenance the finished product of binary foam composite insulation board.
Embodiment 2:
As shown in Figure 2, material therefor and technology are with embodiment 1, and difference is to be evenly equipped with one group of blind hole 3 on the foam substrate 2, also is cast with foam concrete in the blind hole 3.
Embodiment 3:
As shown in Figure 3, material therefor and technology are with embodiment 1, and difference is on the basis of embodiment 2, have increased surrounding edge 4 around foam substrate 2, are cast with described foam concrete in the matrix chamber that surrounding edge 4 forms.
Embodiment 4:
As shown in Figure 4, adopt embodiment 3 described binary foam composite insulation boards,, make the binary foam composite insulation board series of a plurality of different-thickness, make this thickness series form an arithmetic progression (h by the flashing slope requirement that roof building is looked for the slope
N+1-h
n=fixed value, equal difference is not good, but is unfavorable for standardization).The binary foam composite insulation board gradient series of products of described different-thickness are spread to place in order promptly form the ladder slope on the building roof, as shown in Figure 4, handle insulation layer and the sloping layer that promptly forms roofing through seam, levelling.
