The below explains above-mentioned fireproof outer wall heat-insulating to make the process of this fireproof outer wall heat-insulating at the exterior wall wall construction.
1) specific requirement of the fire barrier in fireproof outer wall heat-insulating is as follows:
24m≤H<50m heat insulating material: A level B1 level;
2) construction part of the fire barrier in fireproof outer wall heat-insulating and Specific construction requirement
3) the making construction technology of fireproof outer wall heat-insulating:
(1) base treatment: the base course wall of constructing is reached quality standards through acceptance on examination, should thoroughly clear up former outer plinth course for the metope that does not reach standard-required, reject sudden and violent skin, efflorescence, loosening, crack hollowing part, levelling is cleaned out and repair, reinforced to the residue of metope and release agent.
The dimensional errors of the body of wall basal plane of exterior-wall heat insulation construction should meet following table and require:
(2) unwrapping wire, extension reference line: according to the requirement of elevation of building design and fire barrier, flat, the vertical control line that discharges water is to determine the Specific construction position of fire barrier;
(3) preparation bonding adhesive: press requirement, strict measurement, mechanical agitation is guaranteed to stir.Amount of preparation should be less than the consumption in 1.5 hours;
(4) the bag grid cloth is turned in stickup: the polyphenyl plate of all stickups (warming plate) or fire barrier (foam cement plate or foam glass board) side exposed section (as shrinkage joint, building settlement seam etc.), and all should do grid cloth and turn over the bag processing;
(5) sticking heat-preservation plate: the haftplatte operation is carried out from lower to upper, upper and lower plates answers the fissure of displacement to paste, especially fire barrier and warming plate also must be taked fissure of displacement construction up and down, the bonding mode of warming plate adopts the construction of some frame method, bonding area is more than 40%, and the bonding mode of fire barrier adopts completely sticking method to paste; And warming plate and fire prevention isolation warming plate seam to be reserved the 1cm left and right, after mortar drying to be bonded, carry out joint filling with polyurathamc.After the foamed glue sclerosis, clear up the foamed glue on plate surface, it is fair that foamed glue is polished to the plate face.
Between the same warming plate plate seam spell tight, without " ash of meeting and discussing ", stitch and widely clogs with polyphenyl sheet or the polyurathamc of respective thickness when exceeding 2mm.The piece discrepancy in elevation is not more than 1.5mm, otherwise uses sand paper or the special grinding facility polish flat, and removes surface flotation particle and dust after polishing.
(6) anchoring piece is installed: anchoring piece is installed at least and is carried out after the warming plate plate is pasted 24h.Be screwed into or knock in anchor studs.The anchoring piece of polyphenyl plate is the junction that plum blossom-shaped is fixed on three blocks of plates, due to the fire barrier for full sticking and the warming plate area is less, so do not need to beat anchoring piece, but the junction at two warming plates in edge, fire barrier, anchoring piece 7 (referring to Fig. 1) need to be set, more than fixture guarantees to be connected degree of depth 25mm with concrete base layer, more than aerated blocks or figuline building blocks basic unit are connected degree of depth 40mm.
(7) paving is pressed reinforcing mat: in the junction of fire barrier and warming plate heat insulating material, need to press grid cloth to do with plastering mortar and strengthen processing, the width of grid cloth can not be less than 20cm, and monolithic grid cloth length can not be longer than 6m, and transverse lap is of a size of 10cm.
