Abstract
The construction process of extenal heat-insulating layer expansion polyphenyl plate of wall body includes the following steps: base layer wall body treatment; daubing undersurface of polyphenyl plate with cement, sticking it on the base layer wall body, when sticking, remaining a gap of 5-15 mm between polyphenyl plate and polyphenyl plate; filling said gap with polyurethane adhesive, making polyphenyl plate be foamed in the gap and filling up said gap; grinding external surface of foamed polyurethane filled into the gap, and making the external surface of foamed polyurethane and extenal surface of polyphenyl plate be formed into same plane so as to raise integrated performance of polyphenyl plate; daubing external surface of polyphenyl plate with cement, then laying and sticking mesh fabric, and thickness of cement is 2-3 mm, so that several small blocks of polyphenyl plates can be connected together and made into one body by means of polyurethane foating process.
Description
(1) technical field
The present invention relates to a kind of construction technology of wall outer insulation layer.
(2) background technology
For a long time, construction wall all is that the common brick that adopts clay to fire is built by laying bricks or stones, and is very universal and practical in the specific period.Fast development along with Building Trade in China, the heat-insulating property of construction wall and warming, saving builing industry are more and more paid attention to by people, saving the energy and improving the building thermal technique condition has become pressing for of builing industry and even entire society, particularly has energy-efficient energy saving building exterior wall insulated structure by extensive promotion and application.At present, the energy saving building exterior wall insulated structure mainly contains interior insulation, sandwich wall and three kinds of form of structure of outer insulation.Wherein, interior insulation mainly is meant and adopts steel concrete or common brick brick body as wall body structure, inner hollow core is partly dosed heat insulating material, and the main disadvantage of this type of body of wall is that structure is too thick, and wall weight is too big, materials for wall can not get effective saving, and construction intensity can not get effective minimizing; In addition, inside heat insulation wall body is not owing to eat the finishing that the metal steel nail often influences the room.The sandwich wall construction, promptly composite type wall body mold mainly is meant and adopts polyphenyl plate to do filling, plug-in steel wire is made the mortar plastering layer, and very easily produce distortion during construction and be difficult to control, the constructing operation complexity, the rigidity that forms body of wall is little, and can only bear horizontal loading; Outer insulation is pasted heat insulating material, the plug-in fiberglass gridding cloth of heat insulating material outside mainly being meant on the body of wall that steel concrete or hollow brick are built by laying bricks or stones.The outer heat insulating material that pastes adopts polyphenyl plate, also be the EPS plate, the EPS plate is affixed on the exterior surface of wall, be wrapped in the outside of building tightly just as the thick cotton-wadded quilt of one deck, reduced the coefficient of thermal conductivity of exterior wall effectively, (coefficient of thermal conductivity of EPS plate is 0.035-0.041w/mk) can eliminate the formed cold bridge of body of wall, thereby reduce the heating consumption of building significantly, energy-saving effect is obvious, applied widely, simultaneously can improve the floor space effective rate of utilization and reach 3%-5%, and have performances such as freeze-thawing resistant, atmospheric corrosion resistance.Having above-mentioned series of advantages owing to be incubated to compare with interior insulation and sandwich wall outward, so extensively promoted in builing industry, is the main direction that China's energy-saving residence construction develops.
Chinese patent CN00123456.0 discloses a kind of polyphenyl plate, the floating grey composite thermal-insulating wall of granular polystyrene and construction technology.This process using polylith polyphenyl plate amalgamation is affixed on outward on the surface of wall, has improved the wall thermal insulating effect, still, because exterior surface of wall planeness difference everywhere, the thickness of each polyphenyl plate also is not quite similar and the planeness difference of side, and when pasting polyphenyl plate, the joint that tends between plate and plate has slit or rugged rib, like this, behind linked network and cover, can form local injustice, use a period of time, will ftracture at seam and rib place, thereby cause rain leakage.
(3) summary of the invention
In order to solve the seam that exists between the polyphenyl plate in the above-mentioned outer heat preservation construction and the problem of rib, the invention provides a kind of construction technology of wall insulating layer expansion polyphenyl plate, this technology can avoid external thermal insulation lap-joint slit and rib to occur.Thereby improve cracking resistance, the water proofing property of external thermal insulation greatly.
The technical scheme that adopts is:
The construction technology of wall outer insulation layer expansion polyphenyl plate, its processing step is:
(1) basic unit's body of wall is handled
(2) with the bottom surface daub mud of polyphenyl plate, and stick on basic unit's body of wall, during stickup, make the seam of reserving 5-15mm between polyphenyl plate and the polyphenyl plate.
(3) polyphenyl plate joint filling is inserted in the slit of reserving between the polyphenyl plate with polyurethane adhesive, and polyphenyl plate is foamed in the slit, and fills up the slit.
(4) external surface that will be filled in the polyurethane foam in the slit is polished, and making the external surface of polyurethane foam and the external surface of polyphenyl plate is same plane, thereby has increased the overall performance of fritter polyphenyl plate.
(5) hang grid cloth, the external surface of polyphenyl plate is spread clay, grid cloth in the paving then, the thickness of clay is 2-3mm.
Advantage of the present invention is: a plurality of fritter polyphenyl plate are connected as a single entity by polyurethane foam, and to make the external surface of polyurethane and polyphenyl plate be same plane, solved polyphenyl plate and has occurred the problem that seeps water because of external surface is not gentle because of the slit fracture.
(4) specific embodiment
Embodiment one
The construction technology of wall outer insulation layer expansion polyphenyl plate, its processing step is:
(1) basic unit's body of wall is handled, and is coated with the discarded object that floating ash on basic unit's surface of wall, surface dust, greasy dirt etc. hinder bonding clearly.
(2) clay is spread in the bottom surface of polylith polyphenyl plate, then the polylith polyphenyl plate is sticked on basic unit's body of wall, during stickup, make the slit of reserving 5mm between polyphenyl plate and the polyphenyl plate.
(3) polyphenyl plate joint filling is squeezed into polyurethane adhesive in the slit between the polyphenyl plate with the polyurethane adhesive rifle, polyurethane is foamed in the slit of polyphenyl plate, and fill up the slit.
(4) polishing, making the external surface of polyurethane foam of filling and the external surface of polyphenyl plate is same plane.
(5) hang grid cloth, the external surface of polyphenyl plate is spread clay, glass fiber reticular cloth in the paving then, the thickness of clay is 2mm.
