Abstract

The utility model relates to an inorganic fire-proofing heat-insulating rolling curtain with a heat-resistant deformed plywood, a fire-proofing curtain is arranged at the front row, and a heat-insulating curtain is arranged at the rear row, and the two curtains have a certain distance; the rolling curtain is characterized in that: the plywood on the heat-insulating curtain is composed of long-strip plywood and short-section plywood; the long-strip plywood is arranged on one side of the unexposed surface of the heat-insulating curtain body, the short-section plywood is arranged on one side of the counter-firing surface of the heat-insulating curtain body; the long-strip plywood is transversely and uniformly distributed on the curtain body between a top beam and a bottom beam, the short-section plywood corresponding to the long-strip plywood is uniformly distributed at interval and is connected by a clamping bolt which penetrates through the curtain body; compared with the prior art, the thickness of the heat-insulating curtain is reduced by 50 percent under the same heat-insulating effect, and the temperature at one side of the unexposed surface of the heat-insulating curtain is reduced by 50 DEG C. The inorganic fire-proofing heat-insulating rolling curtain is used as a fire-prevention zone device in various civilian constructions, thereby not only ensuring the fire-prevention quality, but also reducing the production cost, and the appearance of the product is beautiful; the rolling curtain is very suitable for being popularized and used at the occasions such as commercial centers, storehouses and factories.

Description

Inorganic fire thermal-insulated blind with thermal deformation resistant clamping plate

Technical field

The utility model belongs to the what fire services installations, particularly a kind of fire-proof heat insulation rolling curtain.

Background technology

At present, in all kinds of civilian construction, the inorganic fire thermal-insulated blind that is extensive use of the two curtains of double track is made the fire prevention zone device.In the fire prevention zone device of existing structure, the front row of this inorganic fire thermal-insulated blind is a fire screen, back row is an insulating curtain, be provided with spacing between two curtains, curtain body counter-fire face and the fiery face of the back of the body at insulating curtain all adopt the length strip steel clamping plate suitable with curtain body width to press from both sides flat curtain body, curtain body counter-fire face increases rapidly with the temperature difference of the fiery face of the back of the body when breaking out of fire, causing the bar shaped clamping plate of counter-fire face one side to be out of shape greatly because of thermal expansion bends, thereby cause insulating curtain to reduce even connect with the spacing of fire screen, greatly reduced heat-proof quality, made the fire prevention zone device not reach due fire-fighting quality index; If effect of heat insulation is not subtracted, just must increase the thickness of insulating curtain, and increase the spacing of insulating curtain and fire screen, certainly will make the cost of production of fire prevention zone device like this and floor space is installed increases.

Summary of the invention

Above-mentioned defective at the prior art existence, plan is improved existing inorganic fire thermal-insulated blind, manufacture and design a kind of inorganic fire thermal-insulated blind with thermal deformation resistant clamping plate, make it fire prevention zone device as all kinds of civilian construction, can guarantee the fire-fighting quality, can reduce production costs again, and product is more attractive in appearance.

For realizing goal of the invention of the present utility model, the technical scheme of being taked is as follows.

A kind of inorganic fire thermal-insulated blind with thermal deformation resistant clamping plate, the front row is a fire screen, and back row is an insulating curtain, is provided with spacing between two curtains, and it is characterized in that: employed clamping plate are made of rectangular clamping plate and pipe nipple clamping plate on insulating curtain; Rectangular clamping plate are arranged on back of the body fire face one side of insulating curtain curtain body, and the pipe nipple clamping plate are arranged on counter-fire face one side of insulating curtain curtain body; Rectangular clamping plate laterally are distributed on the curtain body between back timber and the bottom girder, and the pipe nipple clamping plate are corresponding with rectangular clamping plate and be interrupted and uniformly pass the curtain body with fishbolt and link to each other.

The inorganic fire thermal-insulated blind of the utility model structure, because counter-fire face one side at insulating curtain curtain body has adopted rectangular clamping plate corresponding link to each other of pipe nipple clamping plate with fiery face one side of the back of the body, and between laterally adjacent pipe nipple clamping plate, be reserved with the heat expansion spacing, therefore the pipe nipple clamping plate can not be out of shape because of thermal expansion and bend when meeting with fire, and it has overcome the defective that the inorganic fire thermal-insulated blind of the two curtains of existing double track exists fully.Experiment shows that it compared with prior art guaranteeing to make insulating curtain thickness reduce 50% under the identical effect of heat insulation, and the temperature that can make insulating curtain carry on the back fiery face one side reduces by 50 ℃.With its fire prevention zone device as all kinds of civilian construction, can guarantee the fire-fighting quality, can reduce production costs again, and product is more attractive in appearance; Promote the use of in places such as it is well suited in the market, storehouse and factory.

The specific embodiment

Further specify the concrete structure of the utility model inorganic fire thermal-insulated blind below in conjunction with accompanying drawing.

A kind of inorganic fire thermal-insulated blind with thermal deformation resistant clamping plate, the front row is a fire screen 1, and back row is to be provided with spacing between insulating curtain 2, two curtains, and it is characterized in that: employed clamping plate are made of rectangular clamping plate 205 and pipe nipple clamping plate 203 on insulating curtain 2; Rectangular clamping plate 205 are arranged on back of the body fire face one side of insulating curtain curtain body 202, and pipe nipple clamping plate 203 are arranged on counter-fire face one side of insulating curtain curtain body 202; Rectangular clamping plate 205 laterally are distributed on the curtain body 202 between back timber 201 and the bottom girder 206, and pipe nipple clamping plate 203 and rectangular clamping plate 205 are corresponding and be interrupted and uniformly pass curtain body 202 with fishbolt 204 and link to each other.
