The flame-retardant modified polyphenyl plate of A level should be from bottom to top, and the horizontal paving of along continuous straight runs, guarantees continuous combination, and the gap of the flame-retardant modified polyphenyl plate of upper row A level and the gap of the flame-retardant modified polyphenyl plate of lower row A level 1/2 plate that staggers is long.
In metope corner, should first sequence size, cut the flame-retardant modified polyphenyl plate of A level, its vertical interlaced is connected, and guarantee corner verticality.
4, the installation of connector 4
Use electric drill to punch with installation connecting element 4.Hole depth on body of wall should be more than 3cm, and what guarantee connector 4 enters the wall degree of depth, and the floated coat of body of wall or old finish coat 6 should be as the degree of depth of connector 4.
Whether the quantity of connector 4 and layout should meet design requirement, and should adopt on-the-spot pull-out test to check its intensity to meet design requirement.
Beaten behind hole, by the plastic disc load hole of connector 4, connector 4 should be after pasting the flame-retardant modified polyphenyl plate 24h of A level, the installation of can holing.
5, the construction of float coat 5
On the flame-retardant modified polyphenyl plate of A level surface, smear first pass plastering mortar, the about 2mm of thickness.This layer is as smeared into for one time, can control material thickness by the sawtooth plaster trowel of 6mm * 6mm～10mm * 10mm: first by the flat side of plaster trowel by even full the smearing on the flame-retardant modified polyphenyl plate face of A level of plastering mortar, with a toothed side, with 60 ° of angles, on plate face, haul out mortar bar immediately, note guaranteeing the full of mortar bar, with flat one, stress new floating mortar and be pressed into grid cloth again, grid cloth position is by following requirement.
Paving grid cloth: grid cloth is tightened to rear appropriateness on bottom plastering mortar, to surrounding, grid cloth is pressed into the top layer of mortar with trowel by centre, smooth compacting, forbid grid cloth gauffer.When paving meets overlap joint, must meet horizontal 100mm, the longitudinally lap length requirement of 100mm.Grid cloth must be pressed in time and be floating when the wet soft state of mortar.Forbid first lapping, then plaster.
Smear plastering mortar second time: after first pass plastering mortar condenses, smear again one plastering mortar, thickness 1～2mm, grid cloth should be positioned at approximately 1/3 place of the outer side of overcoat, must not be outside exposed, also should not imbed too deeply, the visible grid of grid cloth of specifically take be cannot see color as standard.Surface layer mortar be must guard against and not stopped rubbing, in order to avoid form hollowing.Mortar plastering construction intermittently should facilitate the overlap joint of follow-up construction at natural gap, as positions such as shrinkage joint, negative and positive angle, cantilever platforms.On metope, as needed, pausing continuously, surface layer mortar should not cover the grid cloth of having completed completely, need be step slope stubble with grid cloth, first pass plastering mortar, and toothing spacing is not less than 150mm, in order to avoid grid cloth lap-joint planeness exceeds deviation.
6, finish coat 6 constructions
Before coating ornamental surface is smeared, should first on plastering mortar, criticize and scrape flexible putty 2～3 times, putty layer gross thickness be controlled in 2mm; The coating that finish coat 6 adopts should be coating or thick matter decoration mortar is constructed.
