Abstract

A heat-preservation construction method of outer wall dry-hanging stone embedded-in polyurethane rigid foam relates to the building engineering construction technical field. The method is as follows: a stone positioning pothook anchoring body is arranged on an outer wall; a stone is fixed on the outer wall through a pothook; and polyurethane and weather-resisting elastic rubber are poured in the gap between the stone and the outer wall to complete pointing. The heat-preservation construction method is convenient for construction; moreover, the engineering impermeability, the heat conductivity, the water absorption rate and the vapor transmissivity of the method are less than those of the national standard, while the strength, the percentage elongation at rupture, the porosity by closed pore, the density and the cohesive strength are more than those of the national standard. On the premise of the firmness of a dry-hanging stone, the method has better heat-preservation performance.

Description

The polyurethane rigid foam built in dry hanging stone on exterior wall heat insulating construction method
Technical field
The present invention relates to the architectural engineering construction technique field.
Background technology
In recent years, along with rapid development of economy and development of technology, the exterior wall dried hanging stone material is as getting more and more that outside vertical surface of building is decorated, and attractive in appearance, durable, the not allochroic advantage that stone material had more is subjected to people's favor, obtained using widely.China's external wall thermal transmittance and developed country and area be improving constantly along with living standards of the people relatively, requirement to the Building Heat comfort level is also more and more higher, but China external wall overwhelming majority does not reach energy-saving effect at present, reach indoor comfort level, just must strengthen the utilization rate of heating and air-conditioning, promptly to pay more energy cost, face the objective condition of relative inadequacy of resources, resource circulation utilization difference, improve external-wall exterior insulation and water resistance, conscientiously reaching energy conservation standard, is very urgent task.
Summary of the invention
The object of the invention is to invent a kind of polyurethane rigid foam built in dry hanging stone on exterior wall heat insulating construction method of being convenient to construct, reach heat insulation effect.
The present invention includes following steps: exterior wall upload kind of a stone material location hook anchoring body, by hook stone material is fixed on the exterior wall, cast polyurethane, the jointing of weather resisting elastic glue, cleaning stone surface in stone material and exterior wall gap.
In order to realize heat insulation effect preferably, should control the thickness of insulation layer, so the gap between stone material and exterior wall is 25mm.
For guaranteeing the reference plane of stone material, the bonding of the poly-polyurethane of raising foaming is firm, and before the hook stone material, the cleaning wall face floats ash, greasy dirt and hangs and drenches earlier, and adopts the cement mortar screeding plucking.
When the stone material height is big, can adopt the layering spray, every strata ammonia ester foaming height is not more than 500mm.And, during every layer of stone material spray, reserve the height of 100~200mm and follow-up stone material spray simultaneously on top.
The inventive method is convenient to construction, and engineering impermeability, thermal conductivity, water absorption rate, moisture-vapor transmission be all less than national standard, and intensity, fracture elongation, rate of closed hole, density, adhesion strength are all greater than national standard.Before the fastness of dry-hang stone, under the topic, has heat insulating ability preferably.
The specific embodiment
Technological process:
1, the floating ash of cleaning wall face, greasy dirt and extension drench
2, cement mortar screeding plucking
3, according to the stone material modulus at the exterior wall snap the line
4, upload kind of a stone material location hook anchoring body at exterior wall
5, offer hanging groove on stone material, utilize hook that stone material is fixed on the exterior wall, control stone material and exterior wall gap are 25mm.
6, adjust the hook clamp nut, band line centering stone material outer wall installation dimension
7, cast polyurethane in stone material and exterior wall gap
Rigid polyurethane foam insulation layer can be painted on concrete metope and the brick wall.
For realizing no cavity, assurance completely annotates during the insufflation construction, should adopt the layering spray when higher, every layer of foaming height should not be greater than 500mm, should reserve height and the spray simultaneously of follow-up stone material of 100-200mm during every layer of stone material spray on top, with the hard polyurethane foam junction that guarantees twice spray in back and the stone material seam crossing 150mm that staggers.
After the rigid polyurethane foam insulation layer palpus slaking after the spray, can carry out the construction of next procedure.
8, weather resisting elastic glue jointing
9, cleaning stone surface.
