The thickness of above-mentioned levelling setting course polymer mortar is 3～9mm, satisfies the needs of levelling and bonding thickness.The spacing of the mechanical fastening system plastic expansion crab-bolt that above-mentioned vertical, horizontal is arranged in parallel is 200～450 * 200～450mm, optimal spacing is 250～400 * 250～400mm, every square metre 〉=8 of crab-bolt quantity, effective anchorage depth 〉=25mm of crab-bolt, best anchorage depth are 35～45mm; Crab-bolt diameter 〉=8mm, single crab-bolt tension standard value of bearing capacity 〉=0.6KN, the plastic disc small opening pressing plate diameter 〉=60mm of crab-bolt outer end is to guarantee the stability of warming plate.
The external heat insulating wall and the construction technology of above-mentioned mechanical anchor reinforcement modified expanded perlite plate is characterized in that construction technology comprises following processing step:
(1) completely criticizing thickness on basic unit's metope is the polymer mortar levelling of the 3～9mm setting course of holding concurrently;
(2) be adhesive on the wall with the insulation modified expanded perlite plate that is about to accompany in the top layer two-way grid reinforcing rib, form the tight insulation layer; Laying method is that rectangular slab is transversely arranged, and perps is the fissure of displacement line by line, fissure of displacement spacing 〉=200mm, and best fissure of displacement spacing is 300mm, 400mm;
(3) treat to hole at the plate face behind the adhesion strength 〉=0.06MPa of levelling setting course mortar, bore diameter should be identical with the crab-bolt diameter specifications, the plastic expansion crab-bolt of mounting end band plastic disc small opening pressing plate directly is fixed on grid reinforcing rib modified expanded perlite plate on basic unit's body of wall then;
(4) on insulation modified expanded perlite plate face, approach plaster protection surface layer anticracking grout and the construction of finish coat elastic coating at last.
Beneficial effect of the present invention: adopt the fixing external heat insulating wall of bonding to compare with existing modified expanded perlite plate, basic unit's levelling and the auxiliary stickup of warming plate once can be finished, reduce working procedure and duration; Adopt mechanical fastening system anchored grid reinforcing rib modified expanded perlite warming plate, construction technology is simple, easy to operate, and construction quality is easy to control; The combination of this grid reinforcing rib modified expanded perlite plate and crab-bolt has improved tensile strength, rupture strength and the stability of insulation layer greatly.The present invention is particularly useful for the reducing energy consumption of existing building external wall outer insulation; can solve effectively because of the adhesion strength defect of insufficient that flake in the part of the old basic unit of body of wall, crackle or surface contamination barrier film etc. bring; can play a reinforcement, protective effect to original basic unit, improve its stability.
