Description
Technical field
The present invention relates to a kind of exterior-wall heat insulation construction technology, more particularly to a kind of extruded sheet exterior-wall heat insulation construction technology.
Background technology
External thermal insulation system is made up of heat-insulation layer, protective layer and fixed material, it is adaptable to be arranged on exterior wall outer surface
Non-bearing heat-preserving construction general name.The insulation material used in present external wall outer insulation engineering mainly has three kinds：EPS sheet, XPS
Plate and adhesive powder-polystyrene granule thermal insulation mortar.
XPS plate continuity extrusion type polystyrene foam plate is, using vinyl as raw material, continuously to be extruded through special process
The hard plate material of foaming, it is independent closed bubble structure that it is internal, with compression strength it is high, do not absorb water, it is moistureproof, no
Ventilative, lightweight, corrosion-resistant, service life length, the low feature of thermal conductivity factor, are a kind of environment protecting thermal insulating materials of excellent performance.
XPS external thermal insulations structure generally can all be divided into basic unit, tack coat, heat-insulation layer, overcoat.The connection safety of heat-insulation layer and structure sheaf
One of key technology of external wall heat insulation system, be mainly adhesively fixed method, mechanical Fixing Method and both be used in mixed way fixation
Method.The normal produced problem of exterior wall heat-preserving system has：Because sunlight irradiation causes problem of aging；Round the clock, seasonal climate change is drawn
The adhesive mortar risen loses intensity too early, causes warming plate to come off problem；In asking for cold district heat-insulation layer freeze thawing resistance effect difference
Topic.
Adhesive mortar is to be equipped with multiple additives by cement, quartz sand, polymer latex ramming material uniformly to form through mechanical mixture
A kind of mortar.The practicality and durability of the fine or not External Wall heat-insulation system of the performance of adhesive mortar play conclusive influence.
In addition to adhesive mortar, anticracking grout and the decorative mortar also adhesion strength of different degrees of influence heat-insulation system, fold resistance, freeze proof
Property etc..
Present invention optimizes exterior-wall heat insulation construction technology, the preferred formula of adhesive mortar and polymer mortar is improved
Adhesion strength, fracture resistance and the frost resistance of exterior wall heat-preserving system.
The content of the invention
For above shortcomings in the prior art, the technical problems to be solved by the invention are to provide a kind of extruded sheet
Exterior-wall heat insulation construction technology.
The present invention seeks to what is be achieved through the following technical solutions：
A kind of extruded sheet exterior-wall heat insulation construction technology, is comprised the steps of：
(1) putty is prepared；
(2) floating ash, greasy dirt, the releasing agent of base course wall are removed, is rejected and is used in combination for projection, hollowing, porous spot
Putty is levelling；
(3) boundary mortar is prepared；
(4) boundary mortar is smeared on the two sides of extruded sheet；
(5) adhesive mortar is prepared；
(6) adhesive mortar configured is applied to the one side of extruded sheet, is pasted using bar bonding, adhesive mortar will be wiped
Extruded sheet be pasted onto immediately on base course wall；
(7) extruded sheet is pasted and placed 8-24 hours after base course wall, will then in extrusion molding plate surface mounting fixing parts
Polished at extruded sheet seam injustice with coarse sandpaper, it is immediately that extruded sheet chip and floating grey brush cleaning is clean after polishing；
(8) prepared polymer mortar；
(9) polymer mortar configured is uniformly applied on extruded sheet, underlying polymer mortar is obtained, in bottom
Polymer mortar surface is punched, and is then pressed into fiberglass gridding cloth in the underlying polymer mortar punched, is treated bottom sand
Slurry solidification to surface it is tack-free when, in fiberglass gridding cloth surface mounting fixing parts, the position that fixture is installed is gathered with bottom
The hole of compound mortar surface is corresponding, installs after fixture and to smear one layer of polymeric sand again on fiberglass gridding cloth surface
Slurry, obtains surface layer polymer mortar；
(10) it will be polished at surface layer polymer mortar injustice with fine sandpaper, remove the floating ash on surface layer polymer mortar surface,
Then routinely technique carries out surface coating or ceramic tile construction.
A kind of extruded sheet exterior-wall heat insulation construction technology, comprises the steps of, described part is parts by weight：
(1) putty is prepared：100-200 parts of powder of lacquer putty for use on and 50-80 parts of water are added in mixer, 20-30rpm stirrings 7-
10min, stands 15-20min, and then 20-30rpm stirs 3-5min again, produces；
(2) floating ash, greasy dirt, the releasing agent of base course wall are removed, is rejected and is used in combination for projection, hollowing, porous spot
Putty is levelling, and levelling flatness is 0-3mm/2m；
(3) boundary mortar is prepared：30-50 parts of interfacial agents, 30-50 parts of portland cements, 30-50 parts of quartz sands are added and stirred
Mix in machine, 20-30rpm stirring 5-10min are produced；
(4) boundary mortar is smeared on the two sides of extruded sheet, consumption 0.2-0.3kg/m is smeared per face2；
(5) adhesive mortar is prepared：100-150 parts of binding sand starches are added in mixer, 20-30 is added into mixer
Part water, 20-30rpm stirring 5-10min, stands 3-5min, 20-30rpm stirs 1-3min again, produces；
(6) adhesive mortar configured is applied to the one side of extruded sheet, pasted using bar bonding, i.e., will with tooth mouthful trowel
Adhesive mortar is uniformly put on extruded sheet in the horizontal direction, is smeared into strips, the wide 8-10mm of bar, bar thickness 6-10mm, between bar
Away from 50-80mm, the total application area of adhesive mortar accounts for the 30-50% of extrusion molding plate suqare, and the extruded sheet for wiping adhesive mortar is stood
It is pasted onto on base course wall, the one side for smearing adhesive mortar with extruded sheet is pasted with base course wall；
(7) extruded sheet is pasted into placement 8-24 hours after base course wall, then in extrusion molding plate surface mounting fixing parts, often
Square metre 3-10 fixture is installed, fixture is 8-15mm through the aperture that extruded sheet enters base course wall, and fixture anchors into
The depth of base course wall is 48-52mm, then will be polished at extruded sheet seam injustice with coarse sandpaper, immediately by extruded sheet after polishing
Chip and floating grey brush cleaning are clean；
(8) prepared polymer mortar：100 parts of polymer mortar powder are added in mixer, 20-30 parts of water, 20- are added
30rpm stirs 3-5min, then stands 3-5min, produces；
(9) polymer mortar configured is uniformly applied on extruded sheet, smearing thickness is 2-5mm, obtains bottom
Polymer mortar, in the punching of underlying polymer mortar surface, 3-10 hole of every square metre of installation, aperture is 5-10mm, hole depth
For 30-50mm, then by fiberglass gridding cloth, exceptionally straight stretch tight is put down in the horizontal direction, and is pressed into the underlying polymer mortar punched
In, when bedding mortar solidifies tack-free to surface, the position installed in fiberglass gridding cloth surface mounting fixing parts, fixture
Put corresponding with the hole of underlying polymer mortar surface, install after fixture and to smear one layer again on fiberglass gridding cloth surface
