Abstract
The present invention relates to a novel outer thermal insulation construction technique for outer walls, which uses materials such as polystyrene, etc. Polystyrene having the characteristics of small volume weight and no water absorption is used as the thermal insulation material, and polystyrene is firmly stuck to the base surface of the wall preferably by adhesive; sulfur aluminate cement having the characteristic of little shrinkage is used for properly increasing the ratio of sand to ash so as to prevent mortar in the protective layer from cracking; meanwhile, glass fiber grid cloth is used for reinforcing the wall; the coated glass fiber grid cloth having the characteristics of acid resistance and alkali resistance and the sulfur aluminate cement with low alkalinity are used so that the thermal insulation layer is high in durability. The present invention has the advantages of convenient construction.
Description
China carries out " civilian construction energy-saving design standard (heating residential building part) " and makes outstanding achievements in recent years, and Beijing has gained most valuable experience having done a large amount of research and development aspect building energy conservation, the wall thermal insulating and having applied work.With several years ago than, adopt the engineering of External Thermal Insulation Technology for External to increase year by year.
Compare with exterior wall internal insulation, the external wall outer insulation construction technology has the following advantages: prevent that weak node from producing cold bridge, insulating efficiency height; The big insulation layer of thermal resistance is outside the big body of wall of heat capacity, and indoor temperature change generated in case is little, room Heat stability is good, not dewfall; Reduce the thermal stress that solar radiation produces, body of wall is had protective effect; Rational in infrastructure, can not establish air layer, body of wall gross thickness attenuate increases indoor net area; Be convenient to indoor erection equipment and secondary decoration, be applicable to new building construction and the reducing energy consumption of old room.
The external wall outer insulation construction technology remains in following problem: because of environment for use is relatively disliked, produce the crack for preventing outside finish, to material and construction requirement strictness, so the interior insulation of cost is high; Outer heat preservation technology exploitation is later, the cycle is long, designs no foundation, the no rules of constructing, and wet trade is more, and it is unreliable to worry that insulation layer and metope connect, and has potential safety hazard, influences the confidence that Construction unit uses.
Novel external wall exterior heat preserving construction technique of the present invention has that insulation is reliable, security association, the effective advantage of protection.Construction technology of the present invention adopts flame-retardant polystyrene plastic foamboard in light weight, that water absorption rate is little to do heat insulating material, and resistance of heat transfer is stable.It is firm to adopt sticking method of following closely combination that polyphenyl and body of wall are connect, and can resist the high-altitude blast and prevent to come off.The polymer cement mortar that adopts the KE multifunctional adhesive for construction to do modifier and KE dry blend proportioning is made bonding agent and topping, the low and waterproof good penetrability of water absorption rate.Alkali resistant glass fibre open weave cloth is done reinforcing material, and good crack resistance, weatherability and impact strength are arranged.
Details are as follows for novel external wall exterior heat preserving construction technique of the present invention:
Remove scum silica frost, dust and greasy dirt on the metope, fill and lead up residual hole.Fixedly steel wire performs mark and record to measure the basal plane flatness error in inner corner trim, external corner and metope appropriate location.Surpass setting as error, should adopt polymer mortar levelling hair side and maintenance, to prevent the hollowing cracking.Adopt the flame-retardant polystyrene foam to mould plate as heat insulating material, unit weight 〉=18kg/m
3, hot strength 〉=0.1Mpa, specification is 900mm * 600mm usually, according to heating from different places, thickness of slab is 5-8mm.The bonding agent proportioning is the KE dry blend: KE glue=4: 1 once is configured to 50 minutes consumptions and is advisable.It is wide that bonding agent spreads upon polyphenyl plate edge 50mm, and the plate 50mm of staying suitable for reading makes exhaust opening, and the centre is plum blossom point to be arranged, diameter≤100mm, and spacing≤200mm, first floor bond area are 60% of plate area, other layers are 30%, stay the gingival cyst of mucous gland in the newborn stubble at the external corner place.Straight joint about the polyphenyl plate of pasting is forbidden is in time removed the bonding agent of extruding, and requires plate seam≤2mm, the plate surface evenness error≤2mm after the stickup, overproof necessary finishing.Every square metre of 2-3 of mounting fixing parts, go deep into body of wall 〉=35mm.The polymer mortar proportioning is identical with bonding agent, smears on the polyphenyl plate face that glues, and average thickness is 2-3mm.Adopt medium-alkali glass fiber and apply the horizontal mortar surface that is affixed on of grid cloth of the alkaline-resisting resin of one deck, must not gauffer, big external corner, bicker are close to the place, right angle and are strengthened grid cloth, left and right sides lap width 〉=100mm, lap width 〉=80mm up and down along 45 ° of directions overlay 400mm * 200mm in big face grid cloth the inside, go in the mortar with the smooth compacting of trowel, scrape one deck 1mm polymer mortar cover again, forbid grid cloth to expose, gross thickness 3-4mm, the first floor adopts double layer grid cloth to strengthen gross thickness 5-7mm.Mortar be must guard against to rub repeatedly and is formed hollowing in order to avoid cause bleeding.Embed dividing strip reserving lattice seam place, the back of plastering is taken out also in good time and use the guiding ruler deburring, filling polyethylene foamed pole after 24 hours, diameter is wide 1.3 times of seam, the surperficial 10mm of pole arc apex distance, require straight and the depth consistent.Paste adhesive sticker on lattice seam both sides, fill sealing compound and strickling.Look the elevation of building requirement and make concavo-convex moulding, or can adopt concavo-convex coating or flat coating to do outside finish by building requirements.
