Description
Technical field
The present invention relates to wall construction, particularly relate to a kind of external wall construction method.
Background technology
Modern many time limit for project are nervous, and for undertaking of construction, profit is the lowest.Wherein the cost of the construction of brick body body of wall, casting reinforced concrete body of wall and steel construction wall is high, and the cycle is long, and some difficulty of construction are the biggest.
Lightgage steel joist cement plate walling system is currently mainly applied to indoor partition, but owing to exterior wall is different with the requirement of indoor partition, this type of body of wall is applied to external wall system and had not met report, but lightgage steel joist walling system is compared with other external wall system, reduction of erection time can reduce construction cost, it is necessary to find applicable construction method.
Summary of the invention
It is contemplated that overcome the defect of prior art, it is provided that a kind of lightgage steel joist cement plate external wall construction method.The present invention is used on external wall construction, can be effectively improved work efficiency, reduces cost.
In order to solve above-mentioned technical problem, a kind of lightgage steel joist cement plate external wall construction method, it comprises the following steps:
Lightgage steel joist and cement plate installation steps；
Cleaning basic unit step, including waterproof roll paving and the cleaning on waterproof roll surface；
Brushing interfacial agents step；
Wire netting step is installed: wire netting need to select diamond-mesh, and barbed；Not being close to waterproof roll during wire netting paving, wire netting uses self threading pin to be fixed, self threading pin installing space 300-500mm, and blossom type is arranged, self threading pin mount point should make concave surface so that with the spacing of waterproof roll at 7-9mm；
Patch ash cake step；
Scratch coat step, configures including the material parameter proportioning according to producer, and stirs, and selects and either manually or mechanically sprays, and selects depending on field condition；Scratch coat must not exceed 10mm, covers wire netting；
Finish coat step, its method is identical with scratch coat, but the thickness of finish coat must not exceed 20mm, uses batch cutter that surface is received light after having plastered,
And curing step.
Described lightgage steel joist cement plate external wall construction method, described waterproof roll selects the polyurethane water-proof coiled material of concave-convex surface, and coiled material is self-constriction；With broom or hairbrush, waterproof roll surface and oil contaminant etc. is cleaned out, and confirm coiled material and cement plate metope firm pasting.
Described lightgage steel joist cement plate external wall construction method, self threading pin when fixing wire netting need to penetrate waterproof roll and be fixed on cement plate basal plane, guaranteeing that the degree of depth that metope is shot in self threading pin and waterproof roll sealing and self threading pin must not be less than 25mm, singly nail pulling force cannot be less than 0.4KN..
Described lightgage steel joist cement plate external wall construction method, in described patch ash cake step, controls ash cake size, and ash cake must select material equal with body of wall and proportioning identical material when making.
Described lightgage steel joist cement plate external wall construction method, described scratch coat step also includes: must be by compacting of plastering, it is ensured that ash material fills full screening；Scratch coat uses standard tooth form scraper laterally to scrape regular teeth groove, to increase the cohesive force that next layer is plastered after completing；After bottom completes, curing time must not can be carried out next layer plaster less than 3 days after bottom condenses firmly.
Described lightgage steel joist cement plate external wall construction method, after curing time reaches, requires to carry out the decorative model work such as coating application according to designer.
By the method for the present invention, lightgage steel joist cement board wall system can be used on exterior wall, substantially increase work efficiency, meet owner's requirement to the duration；For construction enterprises, once owner allows to use lightgage steel joist cement plate exterior wall, just can reduce cost, increase the benefit.
Detailed description of the invention
Below, in conjunction with detailed description of the invention, the present invention is made a detailed description:
The main clear and definite lightgage steel joist external wall plastering construction technology of the present invention and technology requirement；As a example by 25mm solid cement is plastered, determine that corresponding plastering construction process sequence is: basic unit-brushing interfacial agents-installation metal mesh sheet-patch ash cake-scratch coat-finish coat-maintenance is installed-cleared up to lightgage steel joist.
Plastering construction flow process
Waterproof roll paving
The coiled material of concave-convex surface must be selected during polyurethane water-proof coiled material paving, to increase the adhesive force of surface plastering, and coiled material is self-constriction (self threading pin when fixing steel wire need to penetrate waterproof roll and be fixed on cement plate basal plane, it is ensured that self threading pin seals with waterproof roll).
Base treatment before plastering
With broom or hairbrush, waterproof roll surface and oil contaminant etc. need to be cleaned out, and confirm coiled material and cement backer board metope firm pasting.
Brushing interfacial agents
After web substrates has processed, before plastering, the interfacial agents that producer configures uniformly is painted on waterproof roll surface, in order to strengthen the adhesive force with coiled material of plastering.
Wire netting is installed
Wire netting need to select diamond-mesh, and has agnail (cement mortar free-falling when preventing vertical from plastering)；Not being close to waterproof roll during wire netting paving, wire netting uses self threading pin to be fixed, and self threading pin installing space is advisable with 400mm, and blossom type is arranged, self threading pin mount point should make concave surface so that with the spacing of waterproof roll at about 8mm.And self threading pin shoots the degree of depth of metope and must not be less than 25mm, single nail pulling force cannot be less than 0.4KN.
Patch ash cake
Patch ash cake main purpose ensures depth of plastering and the control of surface smoothness, and ash cake is unsuitable excessive, and ash cake must select material equal with body of wall and proportioning identical material when making.
Scratch coat
During scratch coat, the material parameter proportioning according to producer configures, and stirs, and selects and either manually or mechanically sprays, and selects depending on field condition；Scratch coat must not exceed 10mm, is advisable covering wire netting, but no matter craft or machinery all must be by compactings of plastering, it is ensured that ash material fills full screening；Scratch coat uses standard tooth form scraper laterally to scrape regular teeth groove, to increase the cohesive force that next layer is plastered after completing；After bottom completes, curing time must not can be carried out next layer plaster less than 3 days after bottom condenses firmly.
Finish coat
Finish coat mode is essentially identical with bottom, but the thickness of finish coat must not exceed, and 20mm(is blocked up prevents cracking), use batch cutter that surface is received light after having plastered, after curing time reaches, can require to carry out coating application etc. according to designer.
