Abstract

The utility model relates to a light external wall external heat insulation board, which is a composite board of successively folded 9 layers composed of a glue cement sand layer, a mixed layer of water, cement and glue, a mixed layer of glass fibre grid clothes, water, cement and glue, a polystyrol heat insulation layer of self extinguishing type, a layer of water, cement and resin adhesive, and a layer of glass fibre grid clothes, water, cement, resin adhesive, glue cement sand. The utility model has the advantages of high heat resistance, good heat-insulating property, less outer wall thickness, more effectively utilization of room area, simple structure, which is favorable for commercial process.

Description

Light-duty Outwall thermal insulation board

The utility model relates to a kind of complex heat-preservation building slab, especially the outside bonding complex heat-preservation building slab of building construction exterior wall.Be applicable to residence outer wall, all kinds of public building exterior-wall heat insulation and industrial construction exterior-wall heat insulation.

In the area that needs winter heating, the method of existing house insulation is except using heating equipment, many exterior wall is adopted thickeied wall, as exterior wall clay tile wall or the concrete wall that use 50-72cm thickness more, the weak point of this way is: exterior wall thickness is big, occupy effective usable floor area, used clay can destroy the arable land in a large number.In addition, problem deserving of attention is more, and the heat insulation effect of clay tile wall or concrete wall is poor, and in the winter time, in order to keep certain room temperature, needing increases Fuel Consumption and set up heating system.Therefore the new approaches of the external wall of house of builing industry build recently are: increase the resistive properties of exterior wall 11, reduce winter fuel consumption, reach energy-conservation effect.

The purpose of this utility model is to propose a kind of novel composite external thermal insulation plate that is affixed on the exterior wall outside, compares with the exterior wall 11 of condition of equivalent thickness, and heat-insulating property improves more than 6 times.Accomplish few destruction arable land simultaneously, reduce building area, increase the effective usable floor area in house.

Utility model is to realize like this.1. light-duty Outwall thermal insulation board, comprise bottom and surface layer, it is characterized in that: by glue cement sand bed 1, water, cement and resin adhesive layer 2, glass cross scrim layer 3, water, cement and resin adhesive mixed layer 4, self-extinguishing type polystyrene heat-preservation layer 5, water, cement and resin adhesive mixed layer 6, glass cross scrim layer 7 water, cement and resin adhesive layer 8, glue cement sand bed 9, be built up the composite plate of 9 layers of structure successively.The mixed layer that water, cement and resin adhesive mixed layer 2,4,6,8 cooperate by 1: 1 weight ratio component for water and resin adhesive.Glue cement sand bed 1,9 stirs the cement sand bed that forms for cement water sand weight ratio is that 1: 1.5 and resin adhesive are 1: 1 with the water ratio.Glass cross scrim layer 3,7 is an alkali resistant glass fiber grid cloth.Self-extinguishing type polystyrene heat-preservation layer 5 is a polystyrol plastic foam plate.

The utility model utilizes the general industry material, helps suitability for industrialized production, and is simple in structure, and it is simple and easy to construct.And the thermal resistance value height, according to the GB10294-88 standard detection, the thermal resistance value of 400 * 400 * 38mm plate is 0.805m according to national building materials test center ²K/N, with this plate and 24CM clay tile wall or 20CM reinforced concrete wall compound tense, the thermal resistance of (disregarding air space) combined wall is respectively 1.10 and 0.920m ²K/W, all above the clay tile wall of 62CM, and physical and mechanical property all satisfies standard-required.

Now further narrate structure of the present utility model and embodiment in conjunction with the accompanying drawings.

Referring to Fig. 1-7: the utility model is nine layer materials, and through 10 tons of forcing press high pressure compression moulding composite plate in model, surface layer is that glue cement sand bed 1 is the high-strength plastic cement mortar, and its surface has the effect of smooth facing finishing.

In an embodiment, the light-duty Outwall thermal insulation board of moulding is of a size of 395 * 395 millimeters, 40 millimeters of thickness, 2.3 kilograms of weight, identical with the technology of clay wall or concrete wall 11 bondings and the metope white ceramic tile that bonds outward, use pointing with cement mortar in 1: 1 14 all around at each piece Outwall thermal insulation board.In construction, the sketch plate for special size requires can cut with machine for working stone.Fig. 3,4 has shown that the gyration place of heat-insulation plate for external is that 45 ° of pieces connect 10.C-C cross section is the sectional view at building window place.Shown the annexation of the utility model heat-insulation plate for external 13 among the figure with windowsill 15.

The utility model also is an insulated wall in summer, as long as window is airtight, can intercepts equally in the outside summer heat inlet chamber, as open the window, and indoorly can keep good ventilation.

Embodiment: referring to Fig. 6-7, four sides of surface layer are outward-dipping, in for staying 2mm groove 12 so that fill up cementing agent and combine closely in the bottom surface of pointing with cement mortar 14 bottoms with exterior wall.
