2) lath processing: the extruded polystyrene board selecting condition of equivalent thickness, cuts into lath by extruded polystyrene board;
3) paste lath: the dividing joint center line surveyed according to bullet, paste extruded polystyrene board lath with 108 glue mud;
4) surface layer is built: after 108 glue cement slurry sets, build surface layer mortar or pea gravel concreten, mortar or pea gravel concreten blanking point are seam center of a lattice, first lath both sides are protected with mortar or pea gravel concreten when surface layer is built, lath is prevented to be shifted, then surface construction is carried out, with smearing with press polish during construction;
5) clear up laitance: lath and mortar or pea gravel concreten joint part form induced fractures, clear up extruded polystyrene board lath top laitance with little scoop along attractive joint;
6) roasting seam: baking extruded polystyrene board lath, the pre-thermal contraction of lath forms dividing joint;
7) filleting: the dividing joint outer edge surveyed along bullet pastes Pressure sensitive adhesive tape, carry out filleting construction with bituminous waterproofing caulked joint ointment to dividing joint, filleting height, apart from flat 10mm ~ 15mm on surface layer, is then put down with on silicone structure weather-resistant glue filleting to roofing surface layer, after filleting completes, Pressure sensitive adhesive tape is removed.
Described step 1) in mortar roofing surface layer dividing joint in length and breadth spacing be less than or equal to 1m × 1m; Pea gravel concreten roofing surface layer dividing joint in length and breadth spacing is less than or equal to 3m × 3m.According to roofing size, select suitable dividing joint width, and the center line of dividing joint surveyed by bullet, the width of dividing joint is preferably 10mm ~ 20mm.
Described step 2) in extruded polystyrene board cutting after width of sheet be 15mm.
Described step 3) in 108 glue simulated mud be cement: 108 glue: water=1:0.2:0.4 is mixed.
Described step 6) middle with liquefied gas spray gun baking extruded polystyrene board lath.
Described step 6 and step 7) between dividing joint corner is repaired: 2mm bullet outer edge of going out along dividing joint sideline, grinds 45 ° of oblique angles with sanding machine limit along the line, and with hair-dryer in dividing joint dust remove.
Described step 7) in Pressure sensitive adhesive tape width be not less than 20mm.
The invention has the beneficial effects as follows:
Can efficiency of construction be improved, and can construction quality be improved, reduce labour intensity, save construction cost, reduce the difficulty in work progress.
