Description

A kind of exterior-wall heat insulation construction energy saving technique
Technical field
The invention belongs to skin heat preservation construction field, relate generally to a kind of exterior-wall heat insulation construction energy saving technique.
Background technology
Energy crisis closely becomes the main bugbear that global human is faced jointly at present, and the sleepiness of the energy can stop the step that the mankind advance, and needs the common concern in the whole world and payes attention to.And our country pays much attention to and pay close attention to energy problem, by sustainable development, set up conservation-minded society and classify as the fundamental state policy of China.Wherein External Thermal Insulation Technology for External is as a kind of emerging energy-saving building technology, not only can energy conservation and resource, and improve the utilization rate of the energy and resource.The external thermal insulation system that people often adopt at present, comprise multiple heat insulating material and different construction, such as rubber powder EPS particle slurry outer heat preservation system, cast-in-situ concrete is compound without net EPS plate outer heat preservation system, the compound EPS gauze wire cloth of cast-in-situ concrete outer heat preservation system, EPS plate thinly plastered external insulation system of outer wall, the fixing EPS gauze wire cloth frame plate outer heat preservation system of machinery, rock wool outer heat preservation system, polyurethane outer heat preservation system etc. hard bubbles, in these external thermal insulation systems, wherein EPS plate thinly plastered external insulation system of outer wall has good thermal and insulating performance, superior water resistant, resistance to compression, shock resistance, the advantages such as technology maturation is reliable, to apply at present more External Thermal Insulation Technology for External, but under the condition realizing with texts, fire resistance property and the heat insulation capacity of EPS are poor, environmental pollution is heavier simultaneously.
Summary of the invention
The object of the present invention is to provide the graphite polystyrene foamed material SEPS that a kind of fireproof performance is good can ensure that again thermal property is good, simultaneously energy-conservation construction material, thus guarantee thermal property and the construction quality of construction wall energy-conservation 65%.The present invention relates to a kind of exterior-wall heat insulation construction energy saving technique, realized by following scheme, its concrete steps are:
1) base treatment
The substrate surface of SEPS plate thinly plastered external insulation system of outer wall should thoroughly clean, and without the attachment of the impact such as greasy dirt, release agent bonding, should reject and levelling for projection, hollowing and porous spot simultaneously, and leveling layer planeness is less than 3mm, otherwise should repair smooth.
2) play control line, hang reference line
At external wall angle, (external corner, inner corner trim) and other necessary place hang vertical reference line steel wire, and each floor appropriate location hangs horizon, to control verticality and the planeness of graphite polystyrene board.
3) SEPS plate is pasted
Adopt the fixing SEPS plate of bonding mode of some frame method or the sticky method of bar.
(1), while pasting SEPS plate, adopt completely sticky method, first by the levelling of body of wall basic unit, Base Smoothness is controlled in 3mm, after the full daub stick in the polyphenyl plate back side is scraped with profile of tooth trowel and smeared, sticks at body of wall, while adopting some frame sticky, actual bond area must not be less than 40%.
(3) SEPS plate should be pasted by facing bond mode, and perps is the fissure of displacement line by line, and warming plate face should be smooth, and straight joint does not appear in adjacent S EPS plate while stickup.
(3) between corner place sheet material, want seaming dislocation.The plate of door and window hole four corners position should adopt entire plate to be cut into " L " shape and spread stickyly, must not splice, and should adopt monoblock polyphenyl plate cutting forming, if there is being greater than the seam of 200mm between EPS plate, and the warming plate filling of application same widths.Air-conditioning cavity is waited and should be cut out in advance, reserves position.
(4) EPS plate should do float coat after installing wall in time, and the exposed time should be not long, otherwise has a strong impact on the bonding of plastering mortar and EPS plate.
(5) should adopt double coating way, ensure the tram of fiberglass gridding cloth.Fiberglass gridding cloth should turn at regulation position and wrap and ensure necessary lap length.
4) surface construction
The polymer mortar being stirred is smeared on the SEPS plate posting, thickness average out to 2mm, then grid cloth is entirely affixed on mortar surface layer, enter mortar external surface with trowel concora crush, want smooth compacting, prevent absciss layer, and then smear the polymer mortar cover that the about 1mm of one deck is thick, see that with micro-grid cloth mesh profile is advisable.Grid cloth will ensure lap length, is not less than up and down 80mm, and left and right is not less than 100mm.
The problem that the present invention notes: in heat preservation construction, also carried out corresponding reinforcement processing for the privileged sites in easy generation crack, should do enhancement Layer to privileged sites, its attention aspect is:
(1) bottom spreads double layer grid cloth or adopts gauze wire cloth to replace grid cloth from outdoor ground height 2m scope planted agent;
(2) negative and positive angle place has increased metal protection corner.Carry out part for privileged sites such as choosing window, parapet, plinth, deformation joint, settlement joint and strengthen processing, grid cloth requires to encase the positions such as corner.Press 45° angle bias laid 200mm*300mm at positions easy to crack such as door and window hole and strengthen grid cloth, thermal stresses can not only be disperseed to vertical and horizontal direction, and disperse to 45° angle direction, make thermal stresses obtain disperseing widely, thereby ensured that these positions easy to crack there will not be crack;
(3) after finishing mucilage construction, after natural curing 2~3d, through after the assay was approved, can carry out finish coat construction.Too fast for avoiding dewatering, finish coat should not be under high temperature tans by the sun, carried out, otherwise powdery surface can be formed;
(4) in the construction of anti-cracking protective layer, adopt polymer emulsion the multiple fiber of admixture and Admixture to make antimitotic agent, stir according to a certain percentage and be mixed with anti-crack polymer cement mortar by antimitotic agent and middle fine sand, cement, this anticracking grout plastic deformation performance is good, 5% flexural deformation flawless, permeable pressure ratio is less than 200%, and backfin is than <3, and the stress that the multiple fiber adding can produce material itself fully disperses to surrounding;
(5) the alkaline-resisting plastic-coated fiberglass gridding cloth of full paving in anti-cracking protective layer, consistent through broadwise tensile strength, alkaline-resisting Strength retention is high, 4mm*4mm mesh size is reasonable, the grid cloth using can be dispersed to four direction by stress, thereby make anti-cracking protective layer can adapt to the deformation requirements of wall thermal insulating system, stress that simultaneously also can pair warp and weft direction plays restriction, thereby reaches the object of cracking resistance anticracking.Grid cloth is in the time of overlap joint, and General Requirements must not be less than 50mm.
Technique of the present invention is simple, high insulating effect, adopt graphite polystyrene foam as insulation layer, lighter, safer than traditional heat-insulation system, only has thin 60% of the polystyrene plastoring system weight of moulding of traditional molded polystyrene, and one-tenth-value thickness 1/10 is equivalent to 50% of traditional plastoring system, be easy to meet energy-conservation 65% target.Graphite polystyrene foam has fireproof function simultaneously, and is applicable to any metope, applied range.
