Problems solved by technology
The steel wire of this structure of the fire shutter will easily cut the refractory fiber blanket core and the metal aluminum foil layer during use, causing the product to lose its fire and heat insulation function.
At the same time, due to the poor strength of the refractory fiber blanket, it is easy to be damaged during production, packaging, transportation, installation and operation, forming cracks, holes, wrinkling, packing, and even large-scale accumulation.

Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] Such as figure 1 As shown, the present invention includes a curtain surface 1, a steel splint 2 and a connecting screw 3, wherein the outer layer of the curtain surface 1 is a metal sheet / metal mesh 11, which can be used for anti-theft; the second layer is a refractory fiber layer 12, the third The first layer is an organic fiber layer 13, and the fourth layer is a refractory fiber layer 14. The organic fiber layer 13 is sandwiched between the second layer and the fourth layer, which can not only effectively block smoke, but also effectively strengthen the refractory fiber layers 12, 14. Strength of. Each layer is fixed together by steel splints 2 and connecting screws 3 arranged at equidistant intervals.
[0020] In the above embodiments, the thin metal plate / mesh 11 can be made of iron plate / wire mesh, copper plate / copper wire mesh or stain...

The invention relates to an organic fiber and a refractory fibre compound roller shutter face for a fireproofing heat-insulation roller shutter. The organic fibre and a refractory fibre compound roller shutter face comprises a roller shutter face, steel splints and coupling screws and is characterized in that metal sheets / metal nets are arranged at the outer layer of the roller shutter face, the second layer is a refractory fibre layer, the third layer is an organic fiber layer, the fourth layer is a refractory fibre layer; the organic fiber layer is arranged between the second layer and the fourth layer; the four layers are fixed together by the steel splints arranged at equal intervals and the coupling screws. The organic fibre and a refractory fibre compound roller shutter face not only has good smoke isolation property, but also omits stainless steel wires or stainless steel wire ropes used in the shutter face of the fireproofing roller shutter. The invention also solves the problem that the stainless steel wires or stainless steel wire ropes placed in a refractory fibre blanket can cut open the blanket.
Description
technical field [0001] The invention relates to a fire-proof rolling shutter, in particular to a composite curtain surface of organic fiber and fire-resistant fiber for a fire-proof and heat-insulating rolling shutter. Background technique [0002] With the rapid development of urban construction, there are more and more tall buildings, and people are paying more and more attention to fire safety issues. As a fire compartment partition, fire shutters are widely used in various industrial and civil buildings such as shopping malls, hotels, hospitals, museums, exhibition halls, theaters, airports, high-rise buildings, factories and mines. When a fire breaks out in a building, it can effectively prevent fire, isolate smoke and restrain the spread of fire, and buy precious time for fire protection to achieve the purpose of protecting personnel evacuation and ensuring the safety of life and property. It is an indispensable fire prevention facility in modern buildings. . [0003...
