Description

A kind of exterior-wall heat insulation body

Technical field

The utility model designs technical field of external wall heat preservation, more particularly, to a kind of exterior-wall heat insulation body.

Background technology

With the fast development of construction industry, low-carbon energy-saving concept also enters construction industry.Exterior wall insulated structure is a kind of building The one kind built after the completion of building in external wall can play heat losses in suppression building or prevent outdoor high temperature heat from immersing The building structure of building, fabulous has practiced low-carbon energy-saving theory, with the change of idea, exterior-wall heat insulation also increasingly by Pay attention to；But in existing technology, still there are some defects in exterior wall insulated structure；First, the exterior-wall heat insulation of existing structure Architecture quality causes anxiety, and durability is poor, and the steam in air is easily accessible in structure, causes heat-insulating property to decline, and will also result in Too early damage, second, existing external-wall heat-insulation material uses flammable/inflammable macromolecule foaming plastic foam more, although hair The thermal conductivity of foamed strand foam is relatively low, has good heat insulation effect, but its fire fighting problem is still serious, when fire occurs The easily combustion-supporting intensity of a fire, results in greater loss, third, the combination between each layer of existing external-wall heat-insulation material is weaker, stripping easy to crack Fall.

Utility model content

To solve the above problems, the utility model, which provides one kind, can reduce foamed plastic usage amount, fire can be prevented Gesture spreads and the exterior-wall heat insulation body with good weatherability properties durability.

To achieve the above object, the technical solution adopted in the utility model is as follows：

A kind of exterior-wall heat insulation body, from inside to outside successively by base course wall, screed-coat, heat-insulation layer, lightweight brick layer and external decoration Layer composition；Heat-insulation layer is fixed on outside screed-coat by screed, and outer decorative layer is fixed on outside lightweight brick layer by mortar sheath；Gently There are some columnar projections on matter brick layer surface, and the height of columnar projections is 5~10mm, and columnar projections are embedded in heat-insulation layer；Screed With fiberglass gridding cloth is provided with mortar sheath.

The effect of screed-coat is to make the wall after processing more smooth, and the purpose of screed is integrally fixed at the guarantor outside it Warm structure, heat-insulation layer play main insulation effect in this configuration；The effect one of lightweight brick layer is auxiliary insulation effect, separately One is to play fireproof effect, it is known that foamed plastic is a kind of inflammable/flammable material, event of fire, the intensity of a fire In foamed plastic surface meeting build up, and light-weight brick is a kind of non-flammable inorganic material, is attached on the outside of heat-insulation layer Flame can be obstructed directly to contact with heat-insulation layer, and the columnar projections of light-weight brick layer surface can play barrier insulation material Effect, compared with the harm of small fire；Fiberglass gridding cloth in screed and mortar sheath plays a part of strengthening dependency structure.

Preferably, heat-insulation layer is polyurethane foam, its thickness is 30~80mm.

Preferably, lightweight brick layer is diatomite light-weight brick, its thickness is 20~40mm.

Diatomite lightweight has bigger voidage, and heat-insulating property is more good, and combustion-supporting performance is also good；It is also important Any is, the moisture pick-up properties of diatomite light-weight brick also more preferably, just in case extraneous steam intrusion insulation construction also can be by the danger of steam Evil is minimized.

Preferably, the thickness of screed-coat is 5~10mm.

Base course wall often has following pit and projection because reason, the surfaces such as construction are frequently not smooth, in order to Insulation construction is preferably and wall connecting, it is therefore desirable in wall outer side, screed-coat is set, simultaneously because the purpose of screed-coat, its Need not be too thick, it can also so mitigate the quality of total.

Preferably, outer decorative layer is one kind in gypsum adorned board, marble decorative boards or wood grain decorative sheet.

Preferably, screed uses cement mortar, mortar sheath uses lime mortar.

Screed needs to connect the more insulation construction of screed-coat and outside therefore from the stronger cement bonded sand of bearing capacity Slurry is used as bond material, and mortar sheath is only intended to outer decorative layer being fixed on light-weight brick outer layer, therefore can select more refinement Greasy lime mortar, in the case where playing cohesive effect, moreover it is possible to which preferably the extraneous atmospheric vapour of barrier enters insulation construction internal layer.

Therefore, the utility model has the advantages that：

（1）It is brought into close contact between each layer, the steam avoided in air enters inside configuration, ensures the insulation of insulation construction Performance and durability；

（2）Increase non-ignitable light of fire resisting as main heat-insulation layer and on the outside of foamed plastic using the foamed plastic of suitable thickness Matter brick structure layer, on the premise of heat insulation effect is ensured, the fire protecting performance of total can be strengthened；

（3）Combined closely between each functional layer, be not susceptible to cracking and peel off.
