Its job practices of building exterior wall heat preserving system of the present invention has following relatively more outstanding innovation point:
(1) on interface processing: ordinary mortar whitewashes general and is coated with interfacial agents at concrete material.And thermal insulation mortar will all need to be coated with interfacial agents at all bodies of wall, for guaranteeing polymer thermal insulating mortar not hollowing, cracking, insulation layer and basic unit's adhesive power are strengthened in the interfacial agents effect on the one hand, prevent basic unit's body of wall accumulation of salt in the surface soil on the other hand, destroy the interface and cause hollowing, cracking.
(2) vertical, cover side, bullet control line: whitewash that the degree of plainness for wall surface key is to hang vertically, cover side, bullet control line.Hang vertical, cover side, bullet control line method is whitewashed identical with ordinary mortar, difference is that ordinary mortar control thickness is to have suffered exterior plaster thickness, whether and polymer thermal insulating mortar control thickness is insulation layer thickness, up to standard because the key of heat insulation effect is insulation layer thickness.The outer protective layer thickness of insulation layer is controlled available two kinds of methods and is handled, and the one, directly do topping, because the whole levelling of insulation layer, the 2nd, on insulation layer, play control line again, do ash cake, do the angle, do mouth, carry out the topping construction then.
(3) do ash cake, do the angle, do mouthful: on the good control line of bullet basis, do ash cake, do the angle, to make mouth method identical with ordinary mortar, difference is ash cake, angle THICKNESS CONTROL line difference, the heat-insulation system major control be the thickness of insulation layer.For reducing heat bridge, ash cake is made of thermal insulation mortar, and it is low to do angle section material intensity, constructional difficulties and fragile, and the angular position heat waste is few, does angle section material ordinary mortar.
(4) in the process of whitewashing: polymer thermal insulating mortar insulation layer and ordinary mortar whitewash similar process, all divide the bottoming of twice construction first pass, second time levelling.But insulation layer gene basis body of wall, require the heat insulation effect difference, the insulation layer thickness difference will be divided the multipass construction sometimes, reaches the levelling of ash cake thickness at last.Twice engineering time of ordinary mortar got final product at interval in 3-4 hour, and thermal insulation mortar is slow because of coming on the intensity, and twice engineering time wanted more than 24 hours at interval.
(5) on topping: the common whitewash mortar layer that do not need protection, finish coat is directly done in the outside.And polymer thermal insulating mortar must layer protective layer, its role is to improve the surface impact energy on the one hand, improves the heat-insulation system water resistance on the other hand.The used anticracking grout of topping is to add anti-crack water-proof agent in the common external wall render mortar, and its intensity is higher than polymer thermal insulating mortar.In traditional external rendering process, be not allow outer intensity to be higher than internal layer intensity, be easy to cause hollowing, cracking because do like this.Outer wall outer heat-insulating system of polymer heat-insulating mortar faces same problem.For solving this contradiction; outer wall outer heat-insulating system of polymer heat-insulating mortar is taked two kinds of technological means in construction technology; the one, one deck cushion coat is set between insulation layer and topping; therebetween one deck alkali-resistant glass fibre grid cloth or galvanizing electrowelding net; the crackle that reduces two media interface stress generated by defferent temp and produce; the 2nd, in anti-cracking and waterproofing mortar, add flexible material, improve its plastic deformation ability, prevent cracking.
(6) on cushion coat: the general outer way that is incubated is that reinforcing mat is clipped in the middle of the topping, and this technology way is that cushion coat is set one.It is also different to paste alkali-resistant glass fibre grid cloth method, and other external wall outer insulations are that the topping sequence of construction is to spread one deck finishing mucilage earlier, under the not dried situation of bottom finishing mucilage; grid cloth is sticked; float coat finishing mucilage then, grid cloth can only be pasted by a fritter a small area of ground like this, and overlap joint is many.Polymerization heat-insulating mortar exterior wall outer heat preservation system alkali-resistant glass fibre grid cloth adopts point pasting method, and monoblock is pasted from top to bottom, and overlap joint is few, saving of work and time.
Therefore the present invention has the following advantages:
1, the characteristics of conjugated polymer thermal insulation mortar of the present invention, take into account external rendering construction custom again, promptly solve general external thermal insulation system and easily produce hollowing, cracking problem, overcoming general construction of exterior wall external heat-preservation system again takes a lot of work bothersome, technical difficulty is big, need professional construction troop problem, apply for polymer thermal insulating mortar and similar heat insulating material thereof and lay a good foundation.
2, adopt new polymers heat-insulating mortar exterior wall outer heat preservation system of the present invention to satisfy among the JGJ 134-2001 " Xia Redong cryogenic region energy Saving Design of Residential Buildings standard ", meet the industrial policy of the building energy conservation and the development dry powder and mortar of country the technical requirements of the heat insulation thermal property of building exterior wall heat preserving.
