The fire-proof compound insulation system I
Technical field
The utility model is about a kind of fire-proof compound insulation system I, belongs to external wall outer insulation and building material technical field.
Background technology
In China, the durability of external thermal insulation system has all formed relative perfect method of testing and judgment criteria by using for reference to absorb with autonomous innovation with the validity aspect, and the safety aspect seldom has standards and norms that it is claimed, especially aspect fire savety, all exist always huge potential safety hazard and the time have fire incident to take place.The reality that takes place frequently based on present external thermal insulation system fire, on September 28th, 2009, the Ministry of Public Security united public logical [2009] No. 46 files of word " the fire prevention temporary provisions of civilian construction external thermal insulation system and decoration of exterior wall " of formulation with house and town and country construction portion, just at present the strictness of widely used organic class external wall outer insulation material its scope of application, and external thermal insulation system made in the fire-protection rating of architectural use explicitly called for.
The system that present domestic external wall outer insulation occupies leading position is an exterior insulation system for polyphenyl plate thin plastering exterior wall, use therein main heat insulating material is polyphenyl plate (EPS) and extruded polystyrene board (XPS), two kinds of materials of polyphenyl plate and extruded polystyrene board have light weight, advantage that thermal conductivity is low, are widely used in the exterior wall outer heat preservation system at home in recent years.Yet the fireproof performance of these two kinds of materials is extreme difference but, very easily burning, and discharge a large amount of heats during burning, generate the smog of a large amount of poisonous and harmful character, be subjected to fiery after-contraction fusing to produce cavity, thereby more aggravate burning degree, the dropping of burning has the property of igniting, thereby fire is further spread.Therefore, but has great disaster hidden-trouble at the most widely used heat insulating material of China.
A large amount of at present polyphenyl plate of using are passed through flame treatment, combustibility can reach the B2 level, but the burning grade that improves heat insulating material simply is under present national conditions, will certainly increase energy-conservation cost, moreover add flame-retardant composition (fire retardant) too much and can aggravate burning and release toxic gas on the contrary in case catch fire.Therefore, the fire prevention of external wall outer insulation should be started with from the whole fireproof performance of strengthening system.The combustibility of insulation layer material is the primary condition that influences system's fireproof performance, and the fireproof performance of external thermal insulation system integral body then is the key of fire prevention success or not.
Summary of the invention
Main purpose of the present utility model provides a kind of fire-proof compound insulation system I, combine with the inorganic heat preservation system by the organic heat-insulating system, under the prerequisite of the heat-insulating property of guaranteeing system, improve the fireproof performance of whole system, make it reach desired fireproof performance, cooperate appropriate boundary layer and adhesive mortar layer simultaneously, make whole fire-proof compound insulation system more solid firm, particularly the building heat preservation system at the Xia Redong cryogenic region is more effective.
For reaching above-mentioned purpose, the utility model provides a kind of technical scheme to provide a kind of fire-proof compound insulation system I, it is arranged on basic unit's wall outer side of skin, be provided with the boundary layer of comprehensive laying in basic unit's wall outer side, paste in conjunction with the organic heat-insulating plate with the adhesive mortar layer in the boundary layer outside, this organic heat-insulating plate is adopted at interval and is provided with, the gap and the outside of organic heat-insulating plate are provided with inorganic heat insulation material, and the outside of inorganic heat insulation material is provided with alkaline-resisting grid cloth, anticracking grout layer and finish material successively.
Further, described organic heat-insulating plate is polyphenyl plate or extruded polystyrene board.
The thickness of described organic heat-insulating plate 40 is 20~50mm.
The space distance of described organic heat-insulating plate is 300mm.
Described inorganic heat insulation material is expanded perlite or kervit microbead insulated sand slurry.
The described thickness of being located at the inorganic heat insulation material in the organic heat-insulating plate outside is not more than 8mm.
Fire-proof compound insulation system I described in the utility model, its characteristics are: the optimization of (1) existing polyphenyl plate and extruded polystyrene board system fireproof performance.By architecture Design, under the prerequisite of the heat-insulating property that does not influence system and other physical and mechanical properties, for insulation layer is provided with effective topping; By the structural system of research this type heat insulation system, avoid occurring in the system cavity; (2) laying of boundary layer.Can solve the adhesive mortar layer and combine unstable problem with the basic unit exterior surface of wall; (3) setting of inorganic heat insulation mortar and use.The noninflammability energy that utilizes inorganic heat preservation systems such as expanded perlite, glass bead system is as the fire prevention insulating course, to promote the fireproof performance of whole external insulation system.(4) by alkaline-resisting grid cloth and two kinds of materials of anticracking grout make inorganic and organic heat-insulating layer good be combined into as a whole, thereby promote the overall performance of complex heat-preservation system.
The fire safety problem of external wall heat insulation system is a difficult problem that always perplexs the building heat preservation industry in recent years, and along with the generation of some fire incidents, the fire safety problem of outer insulation more and more becomes the bottleneck that the restriction external wall is incubated industry development outward in recent years.One side present widely used expansion polyphenyl plate/geneogenous disaster hidden-trouble that exists of extruded sheet external insulation system, the inorganic external thermal insulation system that fireproof performance is good on the other hand is difficult to satisfy growing heat-insulating property demand again.The utility model is concentrated the advantage of two class heat insulation systems, designs both to meet the insulation requirement, the external thermal insulation system that has good fireproof performance again; The utility model is equipped with boundary layer at basic unit's exterior surface of wall in addition, effectively raises the linking steady character of heat-insulation system.
