Description
Technical field
The present invention relates to building outer wall insulated fire technical field, be specifically related to a kind of external wall outer insulation fire prevention system.
Background technology
Along with economic development, especially Urbanization In Developing Countries schedule speed is surprising.In this development, urban construction energy-saving and emission-reduction outstanding problem.The unit building area heating energy consumption used of current China is equivalent to 4 times more than of developed country under similar weather conditions.Comparatively speaking, the energy of China is barrenr again, therefore reasonable energy utilization, and improving energy utilization rate is one of main path ensureing economic heath steady development.To the improvement of skin insulation construction power-saving technology, the renewal of insulation, fire proofing material is extremely important to the reduction of building energy consumption and social safety.
Current, applying in China's external wall safeguard structure power-saving technology maximum has three kinds of forms: one, external wall outer insulation; Two, exterior wall internal insulation: three, sandwich heat preservation.Found by comparison analysis, external wall outer insulation protection form resultant effect is the most distinguished, has now become the principal mode of China's wall thermal insulating and the developing direction of energy saving building heat-preserving wall.Exterior wall heat-preserving system is very fast in the development of northern China cold district in winter, and people, while experiencing the excellent energy-saving effect of external wall of house and comfortable living environment, also value the long-term behaviour of this system very much.Under normal circumstances, wall Surgery therapy has a design life requirement, under normal use technology condition, reach this service life, and this just requires that this system has certain durability.But outside finish easily comes off in current many exterior wall heat-preserving systems, there is potential safety hazard, meanwhile waste later period maintenance human and material resources, financial resources.In addition, in exterior wall heat-preserving system, various composition material (comprising auxiliary material) all should possess stable physics and chemistry character.These material requires stand season and cold cycling change, the erosion of rainwater, solar radiation, the caustic corrosion of material self, the repeated action of the corrosion of external microbe and other various stress.But in use for some time, part or whole system ftracture existing many exterior walls protection heat insulating material, come off, efflorescence, heat insulation property are aging, and even some material discharges noxious material.The domestic External Thermal Insulation System of generation in succession fire incident, especially CCTV new address fire, brings about great losses to the country and people's lives and properties.But the heat preserving and insulating material of existing external wall outer insulation engineering large-scale application adopts polystyrene foam, extruded polystyrene foam, polyurethane foam etc. in a large number.These material kinds all belong to organic insulation material, although they have the advantage of lightweight, and heat insulation property is good, and it is yielding, poor fire, easy breaking out of fire, and release poison gas, dangerous people produce and property safety.
In a word, there is many defects in existing building external-wall exterior insulation, fire prevention system.Therefore, overcome these defects, improvement and innovation building exterior wall heat preserving fire proofing material, form good stability, and insulation, fireproof performance are good, and the exterior wall heat-preserving system of Environmental Safety is significant.
Summary of the invention
The object of this invention is to provide a kind of external wall outer insulation fire prevention system, ftracture with solution system, come off, efflorescence, heat insulation property be aging, poor fire, easy breaking out of fire also discharges the technical barrier of poison gas, thus meet good stability, insulation, fireproof performance is good, the demand of the exterior wall heat-preserving system of Environmental Safety.
The present invention is by the following technical solutions:
A kind of external wall outer insulation fire prevention system, comprise base course wall (1), insulation layer (2), fireprotection layer (3), exterior trim surface layer (4), insulation layer (2) is fixed on base course wall (1) by mortar and crab-bolt, fireprotection layer (3) is fixed on insulation layer (2) by adhesive, and exterior trim surface layer (4) is arranged on fireprotection layer (3); Described insulation layer (2) is expanded and vitrified small ball inorganic heat insulation mortar; Described fireprotection layer (3) is rock cotton board or polyurethane fireproof mortar.
Described insulation layer (2) thickness is 30 ~ 50mm.
Described fireprotection layer (3) thickness is 25 ~ 40mm.
Described exterior trim surface layer (4) is dope layer, true mineral varnish, ceramic veneer, marble, granite, metal, curtain wall, polychromy mortar or flexible clay facing tile layer.
Beneficial effect of the present invention:
1, be incubated, fireproof performance is good;
2, physics and chemistry character is more stable;
3, Environmental Safety, energy-saving effect is excellent;
4, the durable use of this system, the life-span same with building itself.
Accompanying drawing explanation
Fig. 1 is external wall outer insulation fire prevention system structural representation.
1: base course wall; 2: insulation layer; 3: fireprotection layer; 4: exterior trim surface layer.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing the present invention done and further explain.The following stated is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
A kind of external wall outer insulation fire prevention system, as shown in Figure 1, comprises base course wall 1, insulation layer 2, fireprotection layer 3, exterior trim surface layer 4.Insulation layer 2 is fixed on base course wall 1 by mortar and crab-bolt, and fireprotection layer 3 is fixed on insulation layer 2 by adhesive, and exterior trim surface layer 4 is arranged on fireprotection layer 3.Insulation layer 2 is expanded and vitrified small ball inorganic heat insulation mortar, and thickness is 30 ~ 50mm.Expanded and vitrified small ball inorganic heat insulation mortar is with glass bead lightweight aggregate for primary raw material, after adding inorganic coagulation material and multiple Admixture, and the inorganic heat insulation mortar made by premixed dry mixing.Coefficient of thermal conductivity is little, high insulating effect, and heat-proof quality is excellent.And soundproof effect is good, can use as sound insulating panel separately.Stay in grade, construction cost are low, good integrity, environmental protection, life-span are long.Fireprotection layer 3 is rock cotton board or polyurethane fireproof mortar, and thickness is 25 ~ 40mm.Exterior trim surface layer 4 can be dope layer, true mineral varnish, ceramic veneer, marble, granite, metal, curtain wall, polychromy mortar or flexible clay facing tile layer etc., according to actual need with selecting.
