Abstract
The present invention discloses an outer insulation wall, it is characterized by the concrete exterior wall surface is equipped with multi-block permeability insulating material, one end of the multi-block permeability insulating material are fixed on the concrete exterior wall surface, and another end is connected with the outer template, the gap between the concrete exterior wall and outer template is injected with polyurethane foaming materials. The normal polymer insulating material has the advantages of high thermal insulation effect and low water absorption ratio, at the same time the air permeability is low, moisture is difficult to transfer, the living suitability is impacted. The present aims at the foaming polyurethane exterior wall insulating system, designs the structure which enhance the air permeability and has thermal insulation property, so the system has certain air permeability while keeps good heat insulation, can further improve the living environment.
Description
Technical field:
The present invention relates to building field, particularly a kind of external heat insulating wall and preparation method thereof.
Background technology:
Along with the national sustainable development implementation, it is imperative to set up conservation-minded society, and energy-conservation requirement is improved constantly.It is one of major technique measure that improves building energy-saving efficient that building adopts heat-preserving wall.Heat-preserving wall is divided into heat preservation system inside and outer heat preservation system, and comparatively speaking, outer heat preservation system has more advantages: effectively protect constructure body structure; Eliminate " heat bridge " phenomenon, avoid dewfall; In body of wall inside generally condensation can not take place; Help keeping ambient-temp-stable; Do not reduce the house usable floor area.Therefore External Walls Heating Insulation had obtained using widely in recent years.
Exterior wall heat-preserving system adopts polystyrol plastic foam plate (EPS, XPS) as heat insulating material substantially at present, after agent structure is finished, with polymer mortar and anchoring piece warming plate is fixed on the agent structure outside, or pours into a mould with concrete.The warming plate surface layer strengthens polymer mortar with the alkali-resistant glass fibre grid cloth and wipes one's face.Also there is producer to develop the foamed polyurethane exterior wall heat-preserving system, can reduces the thickness of external thermal insulation.There is the defective of gas permeability difference in above exterior wall heat-preserving system: the water absorption rate of polystyrol plastic foam plate or polyurathamc is very low, and the permeability of gas is also very low, is in for a long time in the room of this type of materials for wall, can produce the sensation of " unhappy ".
Summary of the invention:
An object of the present invention is to provide a kind of external heat insulating wall that can overcome above-mentioned defective.
To achieve these goals, technical scheme of the present invention is: a kind of external heat insulating wall, comprise concrete exterior wall, it is characterized in that being provided with polylith gas permeability heat insulating material on the concrete exterior wall surface, one end of this polylith gas permeability heat insulating material all is fixed on the concrete exterior wall surface, the other end all is connected with exterior sheathing, injects polyurethane foam material in the gap of concrete exterior wall and exterior sheathing.Wherein the gas permeability heat insulating material is porous cork block, gas concrete piece, perlite products or vermiculite goods.According to one embodiment of present invention, the thickness of each piece gas permeability heat insulating material is 20～80cm, and the diameter of each piece gas permeability heat insulating material is 50mm～200mm, interval 30～70cm between each piece gas permeability heat insulating material.Exterior sheathing is a fiber cement board.
Another object of the present invention provides a kind of external heat insulating wall preparation method that can overcome above-mentioned defective.
To achieve these goals, technical scheme of the present invention is: a kind of external heat insulating wall preparation method is characterized in that it comprises following steps: A, the construction of substrate walls concrete form concrete exterior wall; B, on the concrete exterior wall surface every coverage, fix a gas permeability heat insulating material; C, exterior sheathing is fixed on the gas permeability heat insulating material; D, in the gap of concrete exterior wall surface and exterior sheathing, inject polyurethane foam material.
General high score subclass heat insulating material has the advantage high-efficiency insulated, that water absorption rate is low, but gas permeability is low simultaneously, and steam is difficult for migration, influences the inhabitation suitability.The present invention is directed to the polyurathamc exterior wall heat-preserving system, designed the structure that strengthens gas permeability and have heat-insulating property, make this system when keeping good heat insulating ability, have certain gas permeability, can further improve dwelling environment.
Description of drawings:
Accompanying drawing is a process chart of the present invention
The specific embodiment:
Below in conjunction with drawings and Examples the present invention is further described.
A kind of external heat insulating wall, comprise concrete exterior wall 1, it is characterized in that being provided with polylith gas permeability heat insulating material 2 on the concrete exterior wall surface, one end of this polylith gas permeability heat insulating material 2 all is fixed on concrete exterior wall 1 surface, the other end all is connected with exterior sheathing 3, injects polyurethane foam material 4 in the gap of concrete exterior wall 2 and exterior sheathing 3.
A kind of external heat insulating wall preparation method is characterized in that it comprises following steps: A, the construction of substrate walls concrete form concrete exterior wall 1; B, on concrete exterior wall 1 surface every 30～70cm, fix a gas permeability heat insulating material 2; C, exterior sheathing 3 is fixed on the gas permeability heat insulating material 2; D, in the gap of concrete exterior wall 1 surface and exterior sheathing 2, inject polyurethane foam material 4.
According to the wall heat resistance requirement, the thickness of gas permeability heat insulating material 2 is that insulation layer thickness is 20～80cm, in the gap of concrete exterior wall 1 surface and exterior sheathing 3, inject polyurethane and form insulation layer through foaming, the gas permeability heat insulating material 2 that embeds some in insulation layer is as gas-permeable channels so, and insulation layer integral body still has heat-insulating property preferably simultaneously.According to a preferred embodiment of the invention, gas permeability heat insulating material 2 is a kind of in porous cork block, gas concrete piece, perlite products or the vermiculite goods.The diameter of each piece gas permeability heat insulating material 2 is 50mm～200mm, and exterior sheathing 3 is a fiber cement board.Wherein the construction of the substrate walls concrete of steps A is prior art, and gas permeability heat insulating material 2, polyurethane foam material 4 and fiber cement board 3 are the outsourcing product, do not repeat them here.
Be a specific embodiment of the present invention below.
