Abstract
The present invention relates to a construction technique for filling polyurethane hard bubbles in a wall outer insulation layer. Insulation boards are glued to a base wall processed by an adhesive, the distance of 10 to 30mm is left from the adhesive between the insulation boards and the base wall to the circumferential edges of the insulation boards, and 10 to 100mm gaps are left between the insulation boards. When the adhesive glued to the insulation boards reaches more than 60% of the strength designed, polyurethane hard bubbles are poured in the gaps preset of the insulation boards to make polyurethane foamed and fill up the gaps. The outer surface of the polyurethane hard bubbles is abraded to be in the same plane with the outer surfaces of the insulation boards. Anti-crack mortar of about 3 to 8mm thickness is spread on the outer surfaces of the insulation boards, an alkali-proof net or a steel wire net is embedded, and an anti-crack mortar protective layer is made. The present invention has the advantages that the wall outer insulation layer forms a seamless whole body, quality problems, such as crack, seeping water freeze thawing, fall, etc can be thoroughly eliminated, the use time of the outer insulation layer is extended, and the fire-proofing grade of the outer insulation layer is improved.
Description
Technical field
The present invention relates to a kind of construction technology of filling polyurethane hard bubbles in wall outer insulation layer, is the construction technology of pouring polyurethane foam when the external thermal insulation of body of wall is laid, and belongs to building field.
Background technology
Development along with builing industry; People more and more pay attention to the heat-insulating property of construction wall and warming, the saving energy; Energy-conservation with improve the building thermal technique condition and become pressing for of building trade and even entire society, the energy saving building exterior wall insulated structure that particularly has energy-efficient advantage is by extensive promotion and application.And paste outside on body of wall heat insulating material again the outer wall heat insulating structure of plug-in grid cloth owing to have advantages such as do not take the building usable floor area, be convenient to construction, energy-saving heat preserving is effective; Therefore extensively promoted in builing industry, become the main direction of China's energy-saving residence construction development.
The outer heat insulating material that pastes generally adopts warming plate such as polyphenyl plate materials such as (EPS plate, its coefficient of thermal conductivity are 0.035-0.041w/mk), adopts bonding adhesive that it is sticked on basic unit's body of wall, is doing the anticracking grout overcoat on the heat insulating material again.This technology is fairly simple, and cost is not high, but has plate seam place easy of crack, infiltration freeze thawing and hidden danger of quality such as come off, and makes be difficult to guarantee the service life of external thermal insulation.When the main cause of plate seam place cracking is the warming plate stickup; Stay the slit in jointing positions; Cross over anticracking grout overcoat on this slit because the variation of temperature, humidity, make warming plate act on plate seam place, thereby cause cracking in the stress concentration of shrinking, produce during dilatancy.
Summary of the invention
Problem to be solved by this invention provides a kind of construction technology of filling polyurethane hard bubbles in wall outer insulation layer; It is whole to make wall outer insulation layer form no seam; Can thoroughly eliminate slab-joint cracking, avoid infiltration to cause freeze thawing, and improved the sticking strength of insulation layer; The service life of external thermal insulation can be prolonged, the fire-protection rating of external thermal insulation can also be improved.
The construction technology of filling polyurethane hard bubbles in wall outer insulation layer of the present invention, its processing step is:
(1) basic unit's body of wall is handled, and the floating ash on the removing basic unit surface of wall, surface dust, greasy dirt etc. hinder the discarded object of paste heat-preserving plate;
(2) use bonding adhesive that warming plate is sticked on basic unit's body of wall, during stickup, make bonding adhesive between warming plate and the basic unit's body of wall leave the distance of 10～30mm apart from the edge of this warming plate, and warming plate also leaves the slit of 10～100mm each other;
(3) reach design strength 60% when above when the bonding adhesive intensity of paste heat-preserving plate, hard polyurethane foam is injected the warming plate slit of above-mentioned reservation, polyurethane is foamed in this slit and fill up this slit;
(4) external surface of the hard polyurethane foam after will foaming polishing, making the external surface of hard polyurethane foam and the external surface of warming plate is same plane, promptly appearance is smooth;
(5) spread the thick anticracking grout of about 3-8mm at the external surface of warming plate, embed alkaline-resisting screen cloth or steel fabric sheet, make the anticracking grout overcoat.
Warming plate is can the horizontal paving of along continuous straight runs in a row in the above-mentioned construction technology, and it is long that each arranges between the plate fissure of displacement 1/2 plate.
Employed warming plate can be polyphenyl plate or other light foam plates in the above-mentioned construction technology.
As a kind of preferred version of the present invention, the bonding adhesive between said warming plate and the basic unit's body of wall is 10mm apart from the distance of the edge of this warming plate, and warming plate slit each other is 30mm.
As another kind of preferred version of the present invention, the bonding adhesive between said warming plate and the basic unit's body of wall is 20mm apart from the distance of the edge of this warming plate, and warming plate slit each other is 50mm.
As another preferred version of the present invention, the bonding adhesive between said warming plate and the basic unit's body of wall is 25mm apart from the distance of the edge of this warming plate, and warming plate slit each other is 60mm.
As another preferred version of the present invention, the bonding adhesive between said warming plate and the basic unit's body of wall is 30mm apart from the distance of the edge of this warming plate, and warming plate slit each other is 80mm.
Adopt the construction technology of filling polyurethane hard bubbles in wall outer insulation layer of the present invention; It is whole that the wall outer insulation layer of made forms no seam; Thereby effectively disperse internal stress, can thoroughly eliminate slab-joint cracking, avoid infiltration to cause freeze thawing; And because hard polyurethane foam has characteristics such as hot strength height, self adhesion stress are strong; Can improve the sticking strength of insulation layer, thereby avoid cracking, infiltration freeze thawing that traditional construction technology causes, hidden danger of quality such as come off, can prolong the service life of external thermal insulation; And because the bonding edge sealing of polyurethane also makes every warming plate all form the space of a relatively independent sealing, so can also improve the fire-protection rating of external thermal insulation to greatest extent.
