Description

The outer Insulating aluminium plastic clad plate of a kind of imbedded and fastened hollow heat insulation exterior

Technical field

The utility model relates to a kind of external wall outer insulation composite plate, the heat insulation Aluminiumplastic composite panel of especially a kind of external wall outer insulation hollow.

Background technology

The seventies in 20th century is because after the oil crisis initiation energy crisis, energy conservation is subjected to the great attention of each developed country of the world, and building energy conservation is classified as national fundamental policy.Take measures to control the energy consumption level of new building on the one hand, strengthen transformation on the other hand existing building.The building energy conservation of China is started late, starting from the initial stage eighties is related to the national resources strategy based on building energy conservation, and implementation of sustainable development is related to and expands domestic demand, the major issue that the overall situation of pulling growth of the national economic is work is in the contemporary generation, shade and descendants, promote the well-being of mankind.Under the promotion of government's technical policy and standard, the building energy conservation work of China started fast in recent years, and will welcome a climax, had occurred multiple External Thermal Insulation Technology for External system at home.These technical systems provide the technical guarantee and the motive force of development for building energy conservation work to a certain extent, also need on the performances such as thermal insulation, weather-proof, shock resistance, Wind-Pressure Resistance, fire prevention, ventilative, construction adaptability correctly to estimate and further improve but solve in system, particularly solving on the quality problems of thermal insulation wall surface crack, it is to be solved to still have considerable problem to have.

In recent years, energy-saving building technology develops rapidly both at home and abroad, various advanced persons' power-saving technology occurs, such as: novel self-thermal insulation material walling system; The expansion polyphenyl plate thinly plastered external insulation system of outer wall; The adhesive powder-polystyrene granule thermal insulation mortar external thermal insulation system; EPS plate cast-in-place concrete exterior wall outer heat preservation system; EPS steel wire net rack cast-in-place concrete exterior wall outer heat preservation system; Mechanical fixation EPS steel wire net rack plate exterior wall external heat preservation system; In-situ spraying hard bubble polyurethane exterior wall outer heat preservation system; The rock wool external thermal insulation system; Glue powder polyphenyl particle pastes the polyphenyl board exterior wall outer thermal insulation system; The thinly plastered external wall of extruded polystyrene board outer heat preservation system; The a chain of first exterior wall cladding of SIS heat-insulation system; GKP assembling keel thin plate external thermal insulation system; EVE light thermal-insulation curtain wall panel.

Adopt above External Thermal Insulation Technology for External scheme, compare the thermal insulation of going along with sb. to guard him at building, more than each external thermal insulation system all have the following advantages again:

1, coefficient of thermal conductivity is little, thermal insulation;

2, the protection agent structure prolongs the life-span of building;

3, the basic influence of eliminating " heat bridge ";

4, the body of wall moisture conditions is improved;

5, help room temperature and keep stable;

6, help improving the indoor thermal environment quality;

7, help improving the waterproof and the tightness of body of wall;

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

9, can reduce the heat insulating material consumption;

10, increase the usable floor area in house;

11, the scope of application is wider.

But above various thermal insulation system is on construction and installation and the structure, with material, and fire line, anti-wind pressure still exist a lot of shortcomings and hidden danger on the problems such as thermal insulation wall surface crack quality:

1, harsh to the requirement of thermal-insulation system material;

2, the weatherability of heat-insulation system and poor durability, especially rigidity and hot strength are low;

3, the supporting difficulty of material, the ability of cracking resistance, fire prevention, waterproof, ventilative, antidetonation, Wind-Pressure Resistance;

4, constructor's technical level is uneven, and construction is difficulty relatively, is difficult for installing, and efficient is low;

5, the phenomenon of " heat bridge " fails thoroughly to eliminate, inner easily formation cross-ventilation, frosting easily;

6, the inside and outside wall thermal insulation both sides different temperatures official post exterior wall stereochemical structure lost of life, cracking of wall surface is wayward;

7, coefficient of thermal conductivity instability, most technical schemes does not reach energy-conservation 50% requirement, and the tensile strength discreteness is very big;

8, easy to crack, water resistance is relatively poor, does not match between the main material.After several years,, cause whole system to lose efficacy, will cause the problem that is difficult to keep in repair as if interlaminar failure taking place or peeling off;

9, because the intensity and the hot strength of system are lower, sticking face brick has potential safety hazard.Simultaneously as the glass fiber of skeleton in the insulation layer very easily by the caustic corrosion in the cement paste, breaking strain, safety factor is low.

For the various external thermal insulation systems that present builing industry adopted, we have carried out analyzing to comparing, though advantage is respectively arranged, each scheme exists a lot of shortcomings and hidden danger again.As still there being thermal insulation wall surface crack common quality defect, its existence is the bottleneck of external wall outer insulation heat-insulating technique and development, while construction technology complexity, and difficulty is big, and not easy to operate, quality stability is poor, can not recycling.The time that inappropriate elongation energy-saving index puts in place makes energy-conservation live load too heavy, is unfavorable for the saving of the energy and the pollution of minimizing environment.As the external thermal insulation system that the building main body is gone along with sb. to guard him, it must possess following condition:

1, the designability of material property;

2, high-strength light, anti-fatigue performance is good, and the safety and stability performance is good;

3, anti-seismic performance is good, good weatherability;

4, good heat resistance, thermal insulation is good;

5, shock resistance is good;

6, hot strength and rigidity height;

7, fire protection flame retarding is moistureproof, water absorption rate is low;

8, construction and installation easily, material is easy to get, and cost is low;

9, multi-functional, can be recycled easy installation etc.

Summary of the invention

It is heat insulation that the utility model aims to provide a kind of hollow quick for installation, easy construction, can be recycled the cladding external wall outer insulation Aluminiumplastic composite panel of the imbedded and fastened of replaceable maintenance.

The utility model is realized by following scheme:
