Abstract

A production method of a multifunctional fire-resistant insulation board comprises the following steps: taking a single-side or double-side finished cement flat board as a fire and pressure resistant tensile housing; clamping a bearing framework made of a nonmetallic material in the middle of the housing; filling all gaps with an insulation bonding material, so as to bond all the parts into a whole; and adding a proper number of rust-proof expansion screws according to different usage.

Description

Multipurpose fireproof heated board and production method thereof

Technical field:

The present invention relates to building energy conservation, is a kind of multipurpose fireproof heat insulating plate producing process.

Background technology:

30% of the total power consumption of China building energy consumption account whole society at present is along with its building energy consumption of fast development of town and country construction will be broken through 50% of the total power consumption of society.Retaining wall in the building; Roof of storied building; The ground floor face; Account for 35%, 25%, 15% of building energy consumption respectively, being heat insulating material with polyurethane foam, EPS and XPS plate now generally carries out the external wall outer insulation of 50%, 65% fractional energy savings to public and civil building, and this power save mode has produced the exterior trim pull-up major accidents such as fire takes place frequently that fall; It will be argued that the not only power save mode of instead external wall outer insulation of research and development self-insulation wall material and the finished-product material that possesses fireproof heat insulating simultaneously, and should be as raising building energy conservation index energy-saving and emission-reduction low-carbon economy and building fireproof major fields.The inorganic heat insulation material heat insulation effect that existing fire prevention bearing capacity is high slightly is relatively poor, like foam cement, pearlite slab etc.; Good heat insulation effect organic insulation material then compressive strength is less; And fireproof performance is relatively poor; Like polyurethane foam and EPS, XPS etc., so with the organic or high heat insulating material of the good cement board of the little fireproof performance of the drying shrinkage value parcel effective ways that are fireproof heat insulating.The sharp roof of the general employing of existing in addition roof of storied building design; Its purpose mainly is the transition zone that has increased insulation except that aesthetic; If using high high insulating effect of thermal resistance and resistance to compression, anti-folding, load-bearing, fireproof compound insulating material instead does the insulation of flat roof roof of storied building then can reduce sharp roof significantly; This scheme can reduce building load as implement one in the urban skyscraper, and two can reduce construction cost, and three can increase roof greening, leisure area; Reduce the place that also can hew out leisure, airing the construction costs as in new countryside construction, implementing except that reducing building load, achieve many things at one stroke.

Summary of the invention:

The present invention is achieved in that multipurpose fireproof heat insulating plate producing process is to use single or double finished cement flat board to be fire prevention resistance to compression tension shell; Fold up the pressure-bearing skeleton that nonmetals are made in the middle of the shell; Form integral body with all spaces of heat insulation cementing material filling and with above each several part bonding, install the compression and tensile strength that an amount of antirust setscrew increases this fireproof heated board additional.The fireproof heated board shell generally can adopt the single face cement board to do face-piece to reduce cost in the above each several part, then adopts two cement board shells to increase and the bonding reliability of concrete like double template and the fireproof heated board of doing large die built-in; Nonmetals are made its major requirement of pressure-bearing skeleton: the one, and high thermal resistance; The 2nd, be easy to processing; The 3rd, cost is low, and the 4th, good with the cohesive of heat insulation cementing material, the 5th, frame configuration can be processed shapes such as rectangle, round, stripe shape according to the requirement of purposes and bearing capacity; Heat insulation cementing material chosen one is the thickness of thermal resistance height with the minimizing insulation layer, reduces the cantilever force distance, the 2nd, and good with the cohesive of cement board and nonmetal skeleton, the 3rd, cost is low, and the 4th, be easy to processing; The use of setscrew, as when doing the fireproof heated board of flat roof deck can, as look stretching resistance when doing condition of different such as shear wall formwork and fireproof heated board and require an amount of the use.

The useful effect of multipurpose fireproof heated board that the present invention produced: the one, directly the pressure-bearing insulated fire plate as flat roof deck uses the utilization rate that reduces the investment of sharp roof, reduction load, increases roofdeck; The 2nd, directly the pressure-bearing insulated fire plate as the ground floor face uses; The 3rd, directly the pressure-bearing insulated fire plate as the highrise building shear wall uses; The 4th, directly use as frame structure building beam column pressure-bearing insulated fire plate; The 5th, the insulated fire balustrade exterior panelling that insulation is transformed as existing building uses; The 6th, directly use as frame construction insulated fire infilled wall materials for wall; The 7th, not only be used as the insulated fire plate of shear wall, beam column, ground floor plate, also use simultaneously as the template of Cast-in-place concrete construction technology large die built-in, reduce form cost and labour cost; The 8th, the shell of this fireproof heated board is a cement-based material, and the affinity adhesion stress of itself and cement is higher in above purposes, layering, hollowing, disadvantage such as permeable can not occur; The 9th, need not or use antirust setscrew to increase anti-expansion and tension, the compressive strength of fireproof heated board in right amount according to different purposes.
