The external wall solves the problems of limitation of the height of the wall body and the basic material of the wall body when mosaic tiles are paved on the insulation facing layer outside the external wall under the premise of guaranteeing the safety and quality. The external wall is characterized in that angle steels are uniformly distributed on the basic layer of the lateral surface of the external wall along the horizontal line of a level; the spacing between two adjacent angle steels is 1.5m to 1.5m; other lateral surfaces of the external wall are provided with an insulation layer that is coated by mesh cloth of alkali resistant glass fiber; and facing bricks are arranged on the lateral surfaces that are provided with an insulation layer that is coated by mesh cloth of alkali resistant glass fiber. The external wall creatively adopts rustproof angle steel bracket to unload the insulating brick layer outside the external wall and the facing brick layer; the bracket is used for supporting so that the insulating facing brick layer outside the external wall can be vertically unloaded in sections; thus the external wall solves the problems of limitation of the height of facing bricks and bearing bricks for the external insulation of the external wall, and limitation of the material of the basic layer of the external wall.
Description
Technical field
The utility model relates to a kind of exterior wall with outer wall heat preservation system.
Background technology
Mandatory execution along with national energy-saving heat preserving policy, the coating ornamental surface of the simple property of external heat insulating wall can not satisfy the effect that is designed beautifully, on external thermal insulation wall surface the bonding applique surface brick become designer, developer pursue outside the indispensable a kind of selection of facade effect.But be subjected to the restriction of heat insulating material for external lightweight, low characteristic such as strong, be incubated outside that the bonding applique surface brick is restricted on the surface layer.
In the external wall heat insulation system, the normal at present heat insulating material that uses has: polystyrene foam plate (being called for short polyphenyl plate, EPS), extruded polystyrene board (XPS), an adhesive polystyrene material heat preservation slurry, polyurethane foam material, steel wire net rack sandwich wall board etc.Wherein polyphenyl plate and extruded sheet at home exterior wall be incubated in the plug-in technology and be widely used.This technology is that employing bonding mortar or special-purpose fixedly anchor paste heat insulating material, hang on the exterior wall, smears anticracking grout then, is pressed into fiberglass gridding cloth and forms topping, adds at last and does outside finish.But owing to relate to exterior wall quality and safety problem, general outside finish adopts the coating surface layer more, and several outer rules that all are not incubated direct furring brick in the provincial standard outside that are incubated of the outer insulation industry standard that the Ministry of Construction puts into effect and Beijing's issuing and implementation, therefore, be not difficult to find out, under the condition of not adopting an effective measure, they hold prudent attitude to furring brick on the insulation layer.
External wall outer insulation is not before adopting an effective measure, general direct binding face tile on insulation layer, according to the related experiment digital proof, general heat insulating material does not all reach the adhesion strength standard that meets facing tile country rower, the tensile strength of for example testing polyphenyl plate only is 0.1Mpa, and dry density is 30kg/m
2Polyurathamc or extruded polystyrene board (XPS) is the highest also can not surpass about 0.3Mpa.
Domesticly do face brick on the exterior wall external heat insulating wall, more feasible have following two kinds of schemes:
(1) adopts when doing face brick on EPS plate, the XPS board exterior wall outer thermal insulation surface layer, warming plate density, bond area and anchoring are required to have made regulation, but define simultaneously to be no more than on the outer dado of 6m or other part and can do decorating surface brick in the distance ground level, do face brick for height greater than the position more than the 6m, safety issue can not solve well.
(2) external insulation system of the built-in band steel wire net rack of employing cast in place concrete form, the bonding applique surface brick has been taked a kind of special structure way on this heat insulation system, in the arranged outside of warming plate combine with insulation layer well, certain thickness is arranged, the arrangement of reinforcement cement mortar that higher degree of oozing is arranged, enhancement Layer is to be the anticracking grout of M10 by intensity, in join 40 * 40mm, φ 2 low-carbon (LC) cold drawn wires, and with the 2.5 zinc-coated wires spot welding mutually of passing warming plate, and this mortar enhancement Layer is by tiltedly silk and additional anchor muscle and agent structure (reinforced concrete wall) are connected, the weight of face brick is born by enhancement Layer, and insulation layer does not participate in stressed work.But it must be the full-situ shear wall structure that the limitation of this way is to require outer body of wall, and it is just powerless to mix wall, framework infilled wall etc. for brick.
Adopt decorating surface brick on the heat insulating material of other type,, domesticly lessly see related application or just in R﹠D process as bonding applique surface brick on the heat insulating materials such as glue powder polyphenyl particle, highly dense polyurethane.
Summary of the invention

Have the exterior wall of steel carriage unloading system external thermal insulation, comprise outer body of wall.Improvement is: the lateral surface basic unit upper edge absolute altitude horizon of described outer body of wall uniform angle steel, the spacing between the adjacent angle steel is a 1.5-2.5 rice, metope is close in described angle steel one side, the another side is perpendicular to metope; Other lateral surface basic unit of outer body of wall is provided with the insulation layer of parcel alkali-resistant glass fibre grid cloth, and the lateral surface of the insulation layer of parcel fiberglass gridding is provided with face brick.
Described angle steel is equilateral stainless steel angle steel, and material is the 1Cr18Ni9Ti pickling of stainless steel.
Described angle steel tightens uniform screw on wall covering surface one side, and the center to center distance between the adjacent screw is 600 millimeters, and angle steel is fixed on the wall face by the M12 expansion bolt.
Face brick lateral surface place is provided with silicone sealant perpendicular to the place, outer end, angle steel another side of metope.
Useful technique effect of the present utility model is embodied in following several aspect:
1, creatively using antirust angle steel carriage unloads external wall outer insulation and face brick layer thereof, rely on the support of carriage, outer heat-preserving facing brick layer segmentation vertically unloads to exterior wall, thereby solved a difficult problem that limited by face brick paving height, outer plinth course material in external wall outer insulation upper berth furring brick;
2, external wall outer insulation-antirust angle steel carriage unloading system is carried out joint structure design, solved problems such as the watertightness of external wall outer insulation and weatherability;
3, utilize the antirust angle steel carriage that installs external wall elevation to be separated into the plurality of sections of level, position of joints to partitioning slot adopts flexible material to seal, thereby reduce thermal stresses that external wall insulating layer produces, inner Creep Stress effectively, significantly reduced the appearance in wall face crack;
4, the essential structure of adopting the face brick way to satisfy to the external wall outer insulation wall system of used heat insulating material requires to make substantially and defines, and satisfies the total quality and the safety of exterior wall better.
