Abstract
The present invention relates to a construction process for spraying and pasting polyurethane to an inside corner, an outside corner, and a door/window opening, and a prefabricated polyurethane block thereof. The present invention has the following steps that a wall surface is firstly leveled and processed, moistureproof polyurethane priming paint is painted, and then, a polyurethane heat-insulating layer of a base layer is sprayed in the corner of a wall surface; the thickness of polyurethane is less than design thickness after the polyurethane is sprayed and foamed, and then, a polyurethane prefabricated block in the shape of angle iron is pasted in an edge corner position, such as an inside corner, an outside corner, a door opening, a window opening, etc., and the total polyurethane thickness of the edge corner position coincides with the design thickness; after the polyurethane block of the edge corner position, such as the inside corner, the outside corner, the door opening, the window opening, etc. is pasted, the polyurethane heat-insulating layer of a wall body is continuously sprayed in a large area, a polyurethane interfacial agent is coated on the polyurethane heat-insulating layer, and then, leveling processing, crack resistance processing and finish coat processing are carried out. The thickness of the two right-angle sides of the polyurethane prefabricated block in the shape of angle iron is decreased from the middle part towards tips in a linear mode according to the slope of 5 to 15%. The present invention solves the technical problems that the edge corner position, such as the inside corner, the outside corner, the door opening, the window opening, etc. is difficult to construct and construction speed is slow.
Description
(1), technical field
The present invention relates to a kind of heat-preserving wall negative and positive angle and door and window hole job practices and member.
(2), background technology
In the engineering construction of spraying polyurethane heat-preserving building, the construction of negative and positive angle and door and window hole is a difficult point at the scene, because the material of ejection is a fluid state, what make that body of wall corner after spraying mainly forms is fillet, and verticality and planeness are all bad.And, usually the polyurethane heat-insulation thickness of these edges is than the polyurethane heat-insulation thin thickness of main body body of wall, if reach same thickness, certainly will need the spraying number of times that increase more, but the disperse function during owing to spraying can make most of polyurethane be sprayed on unnecessary place, even has been sprayed on the body of wall outside, this unnecessary urethane raw loss has increased the building operations cost.
For avoiding the problems referred to above to occur, in construction, can adopt negative and positive angle mould tool to come corners such as cast-in-site negative and positive angle and door and window hole.But because the on-the-spot formwork of this arts demand, need dolly set tool on the body of wall, thereby speed of application is very slow.Simultaneously, because problems such as race slurry also can make the various corners appearance of constructing out much be difficult to the problem of expecting, thus the construction speed of having influence on.
(3), summary of the invention
The present invention will provide a kind of polyurethane negative and positive angle and door and window hole spray bonding to close job practices and polyurethane prefabricated section thereof, solves that the negative and positive angle of in-situ spraying polyurethane rigid foam plastic heat-preserving wall and door and window hole are difficult to that construction, speed of application are slow, angle out of plumb, irregular technical barrier.
The technical scheme that polyurethane negative and positive angle of the present invention and door and window hole spray bonding are closed job practices and polyurethane prefabricated section thereof is: verticality and the planeness of checking desire construction metope earlier, as do not reach construction requirement, then should look for vertical and smooth processing with cement mortar to desire construction metope earlier; By the time after the leveling layer drying, on metope, completely brush the moistureproof priming paint of polyurethane; Then begin polyurethane insulation coating in metope bight spraying basic unit; Polyurethane thickness after spraying and the foaming is less than design thickness, begins then angle bar shape polyurethane prefabricated section is pasted at negative and positive angle and position, door and window hole corner, and guarantees the polyurethane thickness that edge is total and the consistency of thickness of design; After the polyurethane prefabricated section pasted, can continue body of wall is carried out the spraying application of large tracts of land polyurethane insulation coating; On polyurethane insulation coating, brush the polyurethane interface agent then and carry out levelling processing, cracking resistance processing and finish coat processing.
The method of attaching of above-mentioned polyurethane prefabricated section is to spray skim polyurethane earlier at pre-position, corner of pasting, and also sprays skim polyurethane simultaneously on the stickup face of polyurethane prefabricated section, immediately the polyurethane prefabricated section is pasted then.
The method of attaching of above-mentioned polyurethane prefabricated section can be pasted with cementing agent.
Polyurethane negative and positive angle and door and window hole spray bonding are closed the polyurethane prefabricated section that job practices is used, it is characterized in that: the polyurethane prefabricated section of described negative and positive angle and the special use of door and window hole edge is angle bar shape, two right-angle sides are wedge shape, its thickness is gradient linear decrease from the middle part to the tip, it is domatic in the outside of two right-angle sides, as external corner polyurethane prefabricated section.
Polyurethane negative and positive angle and door and window hole spray bonding are closed the polyurethane prefabricated section that job practices is used, it is characterized in that: the polyurethane prefabricated section of described negative and positive angle and the special use of door and window hole edge is angle bar shape, two right-angle sides are wedge shape, its thickness is gradient linear decrease from the middle part to the tip, its domatic inner face at two right-angle sides is as inner corner trim polyurethane prefabricated section.
The thickness of above-mentioned two right-angle sides from the middle part to the tip by 5～10% gradient linear decrease.
Thick 20mm～the 50mm of above-mentioned polyurethane prefabricated section, two right-angle side width are 200mm～400mm, length is 500mm～1500mm.
Above-mentioned polyurethane prefabricated section optimum width 300mm.
Above-mentioned polyurethane prefabricated section optimum length is 900mm.
Beneficial effect: in the engineering construction of spraying polyurethane heat-preserving building, the sticking job practices that combines of spray is adopted in negative and positive angle, the equilateral angular position of door and window hole, not only can guarantee the construction thickness uniformity at position, corner, can make the corner do very vertically and smooth again, solve the technical barrier that is difficult to handle the corner in the spraying, also improved speed of application simultaneously than cast-in-site corner.The most advanced and sophisticated place of polyurethane prefabricated section two right-angle sides thickness linear decrease can make spraying application subsequently can not be difficult to control because of the construction abrupt changes in thickness makes construction thickness.
