Description

A kind of polyphenyl plate heat preserving exterior wall

Technical field

The utility model relates to a kind of polyphenyl plate heat preserving exterior wall, can be used for exterior-wall heat insulation, realizes building energy conservation, belongs to the external wall of building technical field.

Background technology

In the peripheral structure of house property building, exterior wall area occupied maximum.Therefore, by the thermal insulation to exterior wall, the energy that reduces building uses and consumes, and is the major measure of building energy conservation.But in the great majority building, exterior wall generally adopts basic unit's body of wall and finish coat structure at present, and this structure outer is not incubated, the thermal transmittance of exterior window also usually can not meet the demands, cause interior temperature too high summer, have only by turning on the aircondition and regulate interior temperature, cause energy consumption to improve.

Summary of the invention

The purpose of this utility model provides a kind of polyphenyl plate heat preserving exterior wall of exterior-wall heat insulation.

For realizing above purpose, the technical solution of the utility model provides a kind of polyphenyl plate heat preserving exterior wall, comprise basic unit's body of wall and finish coat, finish coat is located at outside basic unit's body of wall, it is characterized in that, outside basic unit's body of wall, be provided with insulation layer, between the finish coat of insulation layer and outermost, be provided with the cracking resistance overcoat by tack coat.

Described insulation layer is an expansion polyphenyl plate; Described cracking resistance overcoat is made up of plastering mortar and the alkali resistant glass fibre open weave cloth of imbedding wherein.

The utility model adopts to have certain degree of hardness and better flexible expansion vinylic foam EPS plate is arranged, it is a kind of thermal insulation material, can obtain bigger ripe resistance with less thickness, be compounded in basic unit's wall outer side of heavy, make body of wall have less thermal transmittance and bigger thermal inertia, make body of wall possess Winter protection and summer heat insulating function preferably.

Cracking resistance overcoat of the present utility model is made up of plastering mortar and the alkali resistant glass fibre open weave cloth of imbedding wherein, is used for the protection of outer heat preservation system, to guarantee the mechanical strength and the durability of system.The slight displacement of the polyphenyl plate that the grid cloth available buffer causes owing to reasons such as body of wall displacement, crackings, and the alkalescence that can resist cement and basic mortar.The plastering mortar that is used for armour layer also has certain flexible and more excellent water proofing property except that due tensile bond strength.

The utility model has the advantages that:

1. applied widely

Outer insulation is applicable to the industry and the civilian construction of heating and air-conditioning, both can be used for new construction, can be used for old housing reform again and makes, and the scope of application is very wide;

2, protection agent structure, the life-span of prolongation building

Adopt the external wall outer insulation scheme, because insulation layer places the buildings exterior-protected structure outside, cushioned the stress that causes malformation to produce because of variations in temperature, avoided rain, snow, freeze thawing, do, the structural deterioration that wet circulation causes, pernicious gas and ultraviolet erosion in the air have been reduced to space enclosing structure, as long as body of wall and the selection of roof heat insulation heat-barrier material are suitable, thickness is reasonable, outer insulation can effectively prevent and reduce the temperature deformation of body of wall and roofing, eliminated common diagonal crack or the Eight characters crack of top layer cross wall effectively, therefore, outer insulation both can reduce the thermal stresses of space enclosing structure, again agent structure is shielded, thereby improved the durability of agent structure effectively, so more scientific and reasonable than interior insulation;

3, eliminated the influence of " heat bridge " substantially

Can produce " heat bridge " phenomenon at interior exterior wall interface position, exterior wall collar tie beam, constructional column, Vierendeel girder, post, door and window hole and top layer parapet and roof panel boundary periphery, adopt outer insulation can avoid " heat bridge ", by statistics, bottom room " heat bridge " parasitic thermal load accounts for 23.7% of total heat duties; The room, intermediate layer accounts for 21.7%; Top room accounts for 24.3%, and outer insulation both can prevent the dewfall that " heat bridge " position produces, and can eliminate the additional heat loss that " heat bridge " causes again.Calculating shows, in thickness is the 370mm brick wall under the heat-retaining condition, periphery " heat bridge " makes the body of wall mean thermal transmittance increase about 10% than main body section thermal transmittance: in thickness is the 240mm brick wall under the heat-retaining condition, periphery " heat bridge " makes mean thermal transmittance increase 51%-59% approximately than main body section thermal transmittance, and outside thickness is the 240mm brick wall under the heat-retaining condition, this influence only is 2%-5%;

4, help room temperature and keep stable

External heat insulating wall is because the bigger deck of heat storage capacity in the body of wall inboard, is subjected to unstable heat effect when indoor, and when indoor air temperature rose or descends, the wall body structure layer can absorb or release heat, kept stablizing so help room temperature;

5, help improving the waterproof and the tightness of body of wall

Adopt outer thermal insulation structure, can improve the waterproof and the air-tightness of body of wall greatly;

6, help improving the indoor thermal environment quality

The indoor thermal environment quality is subjected to the influence of indoor air temperature and space enclosing structure surface temperature.As adopt external heat insulating wall, and improve the heat-insulating property of body of wall comprehensively, then help keeping room air and body of wall inner surface that higher temperature is arranged, thereby help improving indoor thermal environment;

7, be convenient to old building and carry out reducing energy consumption

Compare with interior insulation, adopt outer heat preserving mode that old room is carried out reducing energy consumption, one of its great advantage is to need not interim resettlement, does not influence user's indoor activity and normal life substantially.
