Abstract
The utility model relates to a fireproof and smokeproof sealing device for the guide rails of a fireproof roller shutter, which is characterized in that both sides of a fireproof roller shutter are provided with steel guide rails, the opening parts of the guide grooves of the guide rails are oppositely arranged at two sides and are adopted with fireproof and smokeproof sealing strips, and the sealing strips are synchronously embedded at the opening parts of the guide grooves in the forming processes of the guide rails and comprise parts contained in the opening parts of the guide grooves and protruding visual parts. One faces of the protruding visual parts, which are possible to contact with the roller shutter, are circular arc faces. By the smoke prevention device, the product has very good stability under a general environment; and when the temperature is high, the product can be quickly expanded and has the functions of fire insulation, smoke insulation and heat insulation.
Description
Technical field
The utility model relates to a kind of fire separation product, relates in particular to a kind of fire-proof smoke-proof device on the fire curtain guide rail.
Background technology
Poison gas is the main cause that causes casualties in the fire.According to statistics, among the annual personnel because of fire fatality, have nearly 80% to be because of due to the poison gas, therefore strengthen building Smoke prevention measure, reducing flue gas harm is the common problem of inquiring into of whole world fire-salvage specialist.
The fire stops of current a large amount of uses in highrise building, labeled door, fire curtain etc. make the whole building fireproof performance that large increase arranged.But the factor of considering fire separation in building fire protection design is more, and some details have been ignored in building Smoke prevention design, as the Smoke prevention measure in fire curtain guide rail slit, is not considered under normal conditions and is provided with.
Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, thus develop a kind of can effectively stop toxic gas in the fire spread fire curtain guide rail Smoke prevention device.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of fire curtain guide rail Smoke prevention device, it is characterized in that: be provided with steel guide rails in the roller shutter both sides, relative thirty years of age of the guide groove oral area both sides of described guide rail, described guide groove oral area is provided with rubber and plastic fire prevention expansion sealing element, and described seal comprises containing part that is inclusive in the guide groove oral area and the visible part that protrudes in guide groove oral area outside.
Device scheme of the present utility model can also be further perfect:
As preferred version, described guide groove oral area is the right angle face, and the cross section of described seal is that the rectangle arc surface outer with protruding in rectangle combines.Described arc surface is and contacted of roller shutter.
As another kind of preferred version, described guide groove oral area is the acute angle face, and the cross section of described seal is to protrude in the outer arc surface of acute angle face.Described arc surface is and contacted of roller shutter.
The beneficial effects of the utility model are: under common environment, product has good stability; When meeting high temperature, product can expand rapidly, has fire insulation, every cigarette, heat insulating function.
Description of drawings
Accompanying drawing 1 is a kind of structural profile schematic diagram of the present utility model;
Accompanying drawing 2 is another kind of structural profile schematic diagrames of the present utility model.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment 1:
