Description
Technical field:
The present invention relates to side fascia of a kind of construction work use and preparation method thereof, particularly a kind of thermal insulation external wall panel of establishing the airspace layer and preparation method thereof.
Technical background:
The construction work energy consumption accounts for more than 30% of social total energy consumption according to statistics, and country proposes to realize the regulation requirement of building energy conservation 65% for this reason.Domestic construction engineering insulation at present based on heat insulation building block and in basic unit complex heat-preservation, owing to method to set up, the material of insulation layer are used reasons such as improper measures, give the quality of construction work, particularly being incubated the life-span has produced some problems that are difficult to overcome.
Heat insulating material is of a great variety, its physical property and using method are directly connected to heat insulation effect and life problems, classic heat insulating material should belong to hard-foam polyurethane, the coefficient of thermal conductivity of the air under the standard conditions is then near hard-foam polyurethane, at present, domesticly forming insulation layer also not with being applied in the side fascia of the abundant science of air, be a large amount of energy resources of society's saving.
Summary of the invention:
Purpose of the present invention will provide a kind of exactly utilizes air to make insulation layer, make wall, when the indoor and outdoor temperature difference is big, and can prevent effectively that concrete heat-insulating side fascia of dewfall phenomenon and preparation method thereof from appearring in indoor wall.Simultaneously can save a large amount of energy resources, cost is low, and heat insulating effect is good, and can increase usable floor area, significantly shortens the duration of a project, the insulation life-span can with the same life-span of building, and satisfy the structural performance requirement that high antidetonation, anti-high wind are pressed.Can be widely used in concrete frame structure, steel work, Reinforced Concrete Structure and new countryside construction engineering, use as outer ash wall body plate.
The object of the present invention is achieved like this: a kind of thermal insulation external wall panel, it is characterized in that fixedly connected outdoor the concrete layer of steel wire net rack skeleton one side, the fixedly connected indoor surface concrete of opposite side layer, outdoor the inboard fixedly connected insulation layer of concrete layer has the air wall between insulation layer and the indoor surface concrete layer.
Insulation layer of the present invention adopts a kind of in foam cement, expanded perlite, rock wool powder, granular polystyrene rubber powder, the hard-foam polyurethane, outdoor concrete layer and indoor surface concrete layer all adopt high-mark cement, water, artificial hard rock stone sand, SILICA FUME, first level flour coal ash, alkaline-resisting anti-crack fiber, high efficiency water reducing agent to mix together, and requiring the match ratio label is C35-C40.
Preparation method of the present invention is: manufacture steel fabric sheet by zinc-coated wire, form the steel wire net rack skeleton and form, it is characterized in that:
1), manufactures outdoor concrete layer earlier: one bed thickness Polypropylence Sheet on the shock platforms upper berth, shop one deck alkali resistant glass fibre open weave cloth on Polypropylence Sheet, the concrete material that classification is stirred again, all be spread out in above the alkali resistant glass fibre open weave cloth by weight, the steel wire net rack skeleton is placed the concrete material of sharing equally, form outdoor surface layer concrete through vibrations;
2), form insulation layer: hang away after having made outdoor surface layer concrete, treat that concrete strength reaches C5 when above, promptly sprays heat insulating material formation insulation layer on the inwall of this concrete;
3), manufacture indoor surface concrete layer: the inwall for the treatment of insulation layer and outdoor concrete layer bonds and plate is transported back when firm and overturn, be placed on the shock platforms, after reserve the airspace layer thickness, manufacture indoor surface concrete layer according to the way of manufacturing outdoor surface layer concrete again;
4), shutoff: treat around edges of boards, to spray in the cavity when outdoor, interior two sides concrete layer intensity reaches designing requirement the thick 80mm of being not less than hard-foam polyurethane, sealing part around the door and window hole, to the thick hard-foam polyurethane that is not less than 80mm of the inside spray, use the cement expanded perlite slip floating again, thickness is not less than 50mm, so just forms shutoff.
The present invention compared with prior art has the following advantages:
Manufacture steel fabric sheet owing to adopt, to form the steel wire net rack skeleton, to manufacture outdoor surface layer concrete layer, to adhere to insulation layer on the wall within it again, when manufacturing indoor surface layer concrete layer, to reserve the airspace layer, to make the structure and the preparation method of indoor surface layer concrete layer again, thereby:
1, cost is low, can save a large amount of energy resources, raw material.
2, can reach batch production production, exempt traditional building by laying bricks or stones and plastering process again, save a large amount of former material and manually.
3, increase usable floor area 8%-10%, can save a large amount of construction lands, be the space-saving type Building technology.
4, the duration of a project of shortening 2/5ths reduces the construction equipment holding time, saves the construction water electricity consumption, reduces the job site and pollutes.
5, the body of wall of Xing Chenging do not split, do not ooze, elegant in appearance.
6, high-efficiency insulated, and the insulation life-span can with the same life-span of building body.
7, light weight only for existing 1/3 to 1/4 of the complex heat-preservation practice weight of building by laying bricks or stones again, can reduce basis and major project amount input.
8, structural performance height can reach the instructions for use that high antidetonation and high wind are pressed.
9, owing to adopt strong, highly dense, the plastic concrete of steel wire net rack support and connection two sides floor height, the test specimen of having made proves, can satisfy 2.83KN/m
2The Wind-Pressure Resistance instructions for use.Thickness of slab 150mm thermal transmittance is 0.40-0.45.Can realize that floor height 3.9m makes a plate with interior, and can form door and window hole and window covering simultaneously with interior, standard width of a room in an old-style house 6.0m.Also can adjust the thickness of plate and insulation layer according to the various places climatic condition.
