Abstract
The present invention discloses an original state outer heat preservation metope and a construction method thereof; the original state outer heat preservation metope comprises an outer wall, a polyurethane foamed insulating course and a polyurethane foamed protective course; the protective course is made of anti-cracking mortar and is directly coated on the surface of an original state of the insulating course by a spraying way. The construction method of the heat preservation metope of the invention comprises following procedures: the surface of the outer wall is cleaned; a vertical line of the outer wall is hung; the height mark of the thickness is set; doors, windows and internal/external corners are made by the method of spray coating or adhesion; the polyurethane foamed insulating course is coated by the spraying way; the waterproof anti-cracking mortar protective course is directly coated on the surface of the original state of the insulating course by the spraying way. The invention has the advantages of having simple technique and high working efficiency, reducing cost dramatically, improving the insulating effect of the insulating course and the quality of the project, and adding the diversity of the outer insulating metopes.
Description
(1) technical field
The present invention relates to a kind of thermal insulation wall surface, particularly a kind of raw condition external thermal insulation wall surface the invention still further relates to a kind of job practices of this metope.
(2) background technology
The existing thermal insulation wall surface that adopts polyurethane heat-insulation, all be after the spray mo(u)lding of polyurethane foam insulation layer, with the smooth back of the original state surface finish of insulation layer brush one deck interfacial agents, on interfacial agents, smear the 3-5mm plastering mortar, simultaneously in mortar, press the layer of glass fiber net, on glass fiber net, spread one deck anticracking grout surface layer.This kind thermal insulation wall surface operation is many, and waste of material is serious, the construction cost height, and difficulty of construction is big.
(3) summary of the invention
The technical problem to be solved in the present invention is: provide that a kind of operation is few, the raw condition external thermal insulation wall surface of easy construction, and the job practices that a kind of this thermal insulation wall surface is provided.
In order to solve the problems of the technologies described above:
Raw condition external thermal insulation wall surface of the present invention comprises exterior wall, polyurethane foam insulation layer and topping, and described topping is an anticracking grout, and topping is painted on the original state surface of insulation layer.
Described anticracking grout is to add an amount of durafiber and wood fibre in the polymer mortar.
In order to prevent to make topping do the wet excessive crack that occurs of stress when solidifying, described topping is at least two-layer, and first floor is that polymer mortar adds durafiber; thick about 1.5-2mm; the second layer is that polymer mortar adds wood fibre, thick about 1-1.5mm, and gross thickness is 2.5-3.5mm.
In order not only can to obtain preferably environmental effect but also to save construction costs, topping is coated with the finish coat that exterior wall coating material or surface layer mortar are mixed pigment outward.
The job practices of thermal insulation wall surface of the present invention; comprise the steps: to clear up the surface of exterior wall → hang the exterior wall vertical line, thickness absolute altitude → employing spraying is set or the method for pasting is done directly spraying water-proofing anticracking mortar cover of door and window mouth harmonizing yinyang angle → spraying polyurethane insulating foam layer → on the original state surface of insulation layer.
In order to obtain preferably environmental effect and to reduce cost, the surface layer mortar of pigment or the finish coat of exterior wall coating material are mixed in spraying outside topping.
The profitable effect of the present invention: 1, technology is simple: the multiple working procedure of original straight spray method is simplified to Er Sandao, can saves several operation and material.2, work efficiency height: use two spray method constructions (polyurethane directly sprays and the cracking resistance topping directly sprays), spraying polyurethane insulating foam layer 500-1000m
2/ day platform, topping can spray 1000-1500m
2/ day platform.(general Unit 46 floors just can be finished in one or two days.) 3, reduce cost significantly: existing above Haiti district is an example, sprayed originally and plastered general more than 100 yuan every square metre, the about 50-60 of this case cost unit/square metre, be the 1/2-1/3 of original cost, than EPS, XPS plate insulation layer price is also low.4, improved insulation layer heat insulation effect and workmanship: 1. heat insulation effect be EPS, XPS plate 1.5-2 doubly etc., do not have seam not have cold (heat) bridge; 2. adhesive surface 100% no cavity improves the ability that low anti-external cause destroys topping; 3. improve the metope waterproof ability, owing to kept the original state surface (being impervious layer) of insulating foam layer itself to can be used as one deck from waterproofing course.4. the original state surface is that the confining surface layer can stop the adiabatic gas and extraneous slowly exchange in the insulation layer hole.5. because the surface is made up of countless semicircle particles, except thermal insulation wall surface is had booster action, also produce firm bonding with topping, the two can strengthen the anti-crack ability to thermal (temperature difference) stress.5, increase the diversity of heat preserving exterior wall face: the original state exterior wall can be regarded the metope bullet as and be coated with and metope effects such as plucking.The present invention is applicable to that the old housing reform that has a large capacity and a wide range makes engineering.
Description of drawings
Fig. 1 is the structural representation of thermal insulation wall surface of the present invention;
Among the figure: 1, exterior wall, 2, insulation layer, 3, topping, 4, finish coat, 5, the original state surface.
(4) specific embodiment
A kind of as shown in Figure 1 original state heat preserving exterior wall face; it comprises exterior wall 1, insulation layer 2, topping 3 and finish coat 4; insulation layer 2 is the polyurethane foam insulation layer; insulation layer 2 forms countless semicircle particles and forms original state surface 5 after spraying; topping 3 is to be formed by the anticracking grout spraying; anticracking grout is to add an amount of durafiber and wood fibre in the polymer mortar, and topping 3 thickness are 2.5-3.5mm, and finish coat 4 is to mix the pigment spraying by exterior wall coating material or surface layer mortar to form.
The job practices of this original state heat preserving exterior wall face is: comprise that the following step is poly-: the surface of cleaning exterior wall 1 → hang exterior wall vertical line; the method that thickness absolute altitude → employing spraying is set or pastes is done door and window mouth harmonizing yinyang angle → spraying polyurethane insulating foam layer 2; the external surface of insulation layer 2 is original state surface 5 → direct spraying anticracking grout topping 3 on the original state surface 5 of insulation layer 2 that countless semicircle particles are formed; described topping is at least two-layer; first floor is that polymer mortar adds durafiber; thick about 1.5-2mm; the second layer is that polymer mortar adds wood fibre; thick about 1-1.5mm, gross thickness is that 2.5-3.5mm → the surface layer mortar of pigment or the finish coat 4 of exterior wall coating material are mixed in spraying outside topping 3.
