Description

Structure-integrated large mould warming plate containing fire barrier

Technical field

The present invention relates to a kind of structure-integrated large mould warming plate, particularly relate to a kind of structure-integrated large mould warming plate containing fire barrier.

Background technology

Construction formwork is a kind of mould that must use when carrying out major structure of construction cast, is generally steel or wooden template.After the good framework of template support, internally fluid concrete, completes stripping after initial set until concrete, thus completes the infrastructure work of architectural exterior-protecting construction.Therefore, construction formwork is technical tool indispensable in concrete construction process of construction.

And for northern civilian construction, the design standard for energy efficiency of buildings regulation of China must be incubated space enclosing structure, therefore after the infrastructure completing architectural exterior-protecting construction, generally also need the follow-up work that it is incubated, adopt the mode of external wall outer insulation the most general at northern area at present.

Simultaneously because public security and construction industry authorities require more and more higher to the fireproof performance that construction wall is incubated, more and more specifically, therefore the fire barrier plan of establishment is applied in all kinds of wall insulation system more at large.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of structure-integrated large mould warming plate containing fire barrier, complete formwork in space enclosing structure casting process and the exterior-wall heat insulation work in later stage adopting the form of heat insulation formwork simultaneously, next completes the requirement that relevant industrial department specifies to arrange fire barrier not increasing warming plate thickness and site operation workload while, takes into account fireproof performance while heat preservation energy-saving.

For solving the problems of the technologies described above, the invention provides a kind of structure-integrated large mould warming plate containing fire barrier, forming primarily of external protection, insulation layer and inner protective layer.External protection is laid by polymer mortar, inside establishes fiberglass gridding cloth; The fire prevention isolated material that do not fire that insulation layer is A level by organic insulation material and fire-protection rating forms jointly; Inner protective layer is laid by polymer mortar, inside establishes fiberglass gridding cloth.

As the preferred embodiment of described structure-integrated large mould warming plate; insulation layer does not fire fire barrier form by arranging A level in organic insulation material layer; organic insulation material layer directly connects with inside and outside topping respectively relative to two sides, and the relative two sides of not firing fire barrier layer also directly connect with inside and outside topping respectively.

As the preferred embodiment of described structure-integrated large mould warming plate, the width of fire barrier in the vertical direction of itself and adiabator layer phase-contact surface is more than or equal to 100mm, and inner protective layer is 3-10mm, and external protection is 5-20mm.

Design containing fire barrier can improve the fireproof performance of large mould warming plate system under the prerequisite not increasing warming plate thickness, meet energy-conservation and fire-fighting requirements, the structure-integrated large mould warming plate design concept in addition containing fire barrier can reduce the phenomenon manually had high input when on-the-spot fire barrier is arranged simultaneously.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Fig. 1 is the structure-integrated large mould warming plate Longitudinal cross section schematic containing fire barrier;

Fig. 2 is the Longitudinal cross section schematic of the structure-integrated large mould thermal insulation layer of thermal insulation board containing fire barrier;

Fig. 3 is that structure-integrated large mould warming plate containing fire barrier is respectively in the cross sectional representation at organic insulation material layer and adiabator layer place, fire barrier.

Detailed description of the invention

As shown in Figure 1, the structure-integrated large mould warming plate containing fire barrier forms primarily of inner protective layer 1, insulation layer 2 and external protection 3.External protection 3 is laid by polymer mortar, inside establishes fiberglass gridding cloth; The fire barrier material that do not fire that insulation layer 2 is A level (containing A1 level and A2 level) by organic insulation material and fire-protection rating forms jointly; Inner protective layer 1 is laid by polymer mortar, inside establishes fiberglass gridding cloth.

As shown in Figure 2, by fire-protection rating be A level (containing A1 level and A2 level) do not fire any suitable location that the fire barrier that forms of fire prevention isolated material can be arranged in organic insulation material, as top, the first half, middle part, Lower Half or bottom.Organic insulation material layer 4 directly connects with inside and outside topping two sides relatively respectively, and the relative two sides of not firing fire barrier adiabator layer 5 also directly connect with inside and outside topping respectively.

Fig. 3 shows structure-integrated large mould warming plate containing fire barrier respectively at the cross section at organic insulation material layer 4 and fire barrier adiabator layer 5 place.

For example, do not fire the width H of fire barrier adiabator layer in the vertical direction of itself and organic insulation material layer phase-contact surface and be more than or equal to 100mm, the thickness of inner protective layer 1 is 3-10mm, and the thickness of external protection 3 is 5-20mm.

In construction, the structure-integrated large mould warming plate containing fire barrier of the present invention can be applied according to the following steps.

(1) the structure-integrated large mould warming plate containing fire barrier of different-thickness is selected according to energy-saving design in construction file.

(2) the structure-integrated large mould warming plate containing fire barrier is produced according to building storey height design.

(3) during construction, template is vertically settled, and splice according to sequence of construction from left to right, guarantee the strict overlap joint of splicing seams simultaneously.

(4) braced structures of support template, guarantees that heat insulation formwork is indeformable in casting process.

(5), after concrete initial set to be cast, remove supporting and protection structure, the structure-integrated large mould warming plate containing fire barrier is forever retained in construction wall system.

Be appreciated that under the prerequisite not deviating from inner characteristic of the present invention, type of the present invention also can have various deformation, is not limited in the concrete structure of above-mentioned embodiment, and do the understanding of broad sense in the scope that should limit in claim.In a word, the present invention should comprise those apparent conversion or alternative to those skilled in the art.
