Description

A kind of extruded polystyrene board of anti-crack thermal insulation
Technical field
Building exterior wall heat preserving apparatus field is the utility model is related to, particularly a kind of extruded polystyrene board of anti-crack thermal insulation.
Background technology
As socialist market economy quickly increases, Development of Urbanization also achieves very big process, due to its people The raising of economic condition, people have different degrees of requirement to the environment of life, the condition of inhabitation;And house is urbanization hair Important flag during exhibition, control residence outer wall extruded polystyrene board have hair when being incubated the problem of crack is seeped water, heat-insulation layer comes off It is raw, so the security, the attractive in appearance and comfort level that improve residential housing are the most important things.
Because external insulation system is located on the outside of exterior wall, directly bear to influence from nature various factors, to system requirement It is higher.For solar radiation and variation of ambient temperature influence on it, the anti-cracking protective layer being placed on heat-insulation layer only has 3mm ~20mm, and insulation material has a larger thermal resistance, the cracking resistance of the pliability and weatherability of anti-cracking protective layer to external insulation system Performance plays the effect of key.
In at this stage, deficiency existing for the design of conventional extruded polystyrene plate thin plastering external thermal insulation thermal insulation construction, reason is: Heat preserving and insulating material generally use is pasted plus crab-bolt supplementary anchorage is fixed on base course wall, and sand of wiping one's face then is smeared on warming plate Starch and enhancing net laying is pressed in decorative mortar.Autogenous shrinkage deformation time of the warming plate in natural environment is up to 60 days, Because the autogenous shrinkage deformations of 5 days under the conditions of 42 days under natural environmental condition or 60 DEG C of steam curings have completed 99% More than, therefore it is required that warming plate under natural environmental condition under the conditions of 42 days or 60 DEG C of steam curings after 5 days again on wall, But it is difficult to accomplish in a practical situation.
, should when being glued using pure point meanwhile the pure point of extrusion molding plate thin plastering external thermal insulation thermal-insulating system generally use is viscous or basket point glues The cavity integrally penetrated be present in system.The system exist the cavity positive and negative blast that integrally penetrates insulation metope squeeze or Draw, also easily cause and ftractureed at plate stitch, blast is born under extreme case can even take warming plate off.
Moreover, it is only 3mm mortar composite gridding cloth overcoat on polyphenyl plate heat preserving layer, because polyphenyl plate heat preserving is heat-insulated Layer thermal resistance is very big so that the heat of overcoat not easily passs through conduction diffusion, difference variation and by round the clock with gas outside season room The influence of temperature, the durability of pliability and grid cloth to decorative mortar propose at a relatively high requirement.
The content of the invention
Technical staff has found in long-term site operation observation, and the main reason for causing the deficiency of technology at this stage exists In:The high distortional stress caused due to self-deformation and temperature deformation of extruded sheet intensity bigger than expansion polyphenyl plate density is also big; The anticracking grout of preparation is excessively thin or blocked up all easy cracking;Decorations material pliability difference can cause to ftracture.
The purpose of this utility model is exactly to solve the various deficiencies in the prior art in external thermal insulation thermal insulation construction structure.

Preferably, the extruded sheet clathrum is made up of steel fabric sheet, and the position-limit mechanism is installed on the steel fabric sheet At the node of grid.The limiting rivet, auxiliary nut, installation nut are made up of PVE.The grid cloth is covered and exceeded described Extruded polystyrene board bottom 40cm, to adapt to the frame of wall.
Or it is described installation nut towards the side of exterior wall be prism-frustum-shaped, to form pressurization inclined-plane.
Or, it is nested with again in the screed provided with grid cloth, is provided with the grid cloth and intersects along direction of warp and weft The positioning towed rope of distribution, the diameter of the positioning towed rope are corresponding with the groove width of the locating groove so that the positioning Neck is spacing to the grid cloth.
The beneficial effects of the utility model are:
(1)A kind of structure for homogenizing local stress in styrofoam is devised, reduces its concentrated stress, reduces exterior wall(1) Crack infiltration, heat-insulation layer come off;
(2)Material is pasted using the whole plate of lightweight, easy to operate, short time limit, and related connection member also uses lightweight knot Structure is small to the burden of metope;
(3)The design of position-limit mechanism ensure that the stabilization of each aspect pressing, meanwhile, light weight, double-deck nut is designed with Beneficial to installation, the laying of later stage grid cloth and mortar is also beneficial to, the design of locating groove further limits grid cloth Displacement, improve the performance of product crack resistence;
(4)During design, according to the structure situation of building, heat-insulation system interface is rationally designed, discharges the contraction of warming plate, Avoid the accumulation of shrinkage stress;The concavo-convex position of metope is reduced, avoids shrinkage stress from concentrating;The quantity of anchoring piece is properly increased, Improve anti-crack ability;The high alkaline-resisting grid cloth of cracking resistance, and the lap of splice at least more than 10cm are spent using quality is good, product is qualified;
(5)Grid cloth paving, overlap, turn over bag, the further perfect patch between product quality and each layer of its node processing It is right.
