Description
Technical field
The utility model relates to a kind of rolling door.
Background technology
China's utility model patent discloses a kind of swing cover type rolling door for No. 93239600.3, this rolling door is made of doorframe, spool and curtain body, spool vertically is arranged at a side of doorframe, one end of curtain body links to each other with spool, be provided with gathering sill at the corresponding position of doorframe and limit, curtain side, the side of curtain body is embedded in this gathering sill.In order to prevent fires, this swing cover type rolling door also in the outer setting of upper door frame fire main and shower nozzle.With regard to this swing cover type rolling door, its novel structure, and have fire-proof function concurrently, thus have certain advantage.But find in actual use, can play certain anti-fire action though fire main and shower nozzle are arranged on the outside of upper door frame, but be exposed to outer fire main and shower nozzle and be easy to laying dust and corrosion, then might cause problems such as spray orifice obstruction behind the shower nozzle laying dust, can not guarantee the realization of its fire-proof function.In addition, for fire prevention effectively, the spray orifice of shower nozzle usually should be towards the curtain face of curtain body.But, owing to be subjected to the obstruct of doorframe framework, also need be provided with parts such as bend pipe and just can reach above-mentioned requirements, thereby make the structure of product be tending towards complicated at the rear portion of shower nozzle, increased the manufacturing cost of product.Certainly, above-mentioned fire main and shower nozzle also need to be provided with separately when rolling door is installed and to install, and have increased the installation workload of rolling door; Simultaneously, being exposed to outer fire main has not only influenced the attractive in appearance of user environment, has also additionally taken user's space, has caused obstacle for user's daily operation.Just because of top all disadvantages, the user who has even is not willing to be intended to be provided with in the horizontal rolling door above-mentioned fire main and shower nozzle yet.Therefore, in order to improve the performance of product, be necessary this existing product is improved.
The utility model content
The purpose of this utility model is that the fire proof construction to above-mentioned existing product improves, and the side direction type steel steam fog fire curtain that a kind of structure is comparatively simple, cost is lower, easy for installation, be convenient to user's maintenance and use is provided.
The purpose of this utility model realizes in the following manner: fire main is arranged in the last gathering sill of doorframe, shower nozzle no longer is set, and directly offers hole for water spraying on fire main.Specifically, side direction type steel steam fog fire curtain of the present utility model is made of doorframe, spool and curtain body, spool vertically is arranged at a side of doorframe, one end of curtain body is fixed on the spool, upper side frame and lower frame at doorframe are respectively arranged with gathering sill and following gathering sill, the upper side edge of curtain body and lower side embed respectively in the described upper and lower gathering sill, it is characterized in that fire main is arranged in the gathering sill, offers hole for water spraying on the tube wall of this fire main.During side direction type steel steam fog fire curtain in using the utility model, the user can be connected fire main earlier with water pipe, and relative set water supply control valve door artificial or that control automatically.In case breaking out of fire can be closed rolling door, and open the water supply control valve door, allow current enter fire main.The current that enter fire main outwards spray through hole for water spraying, and the curtain surface that will be deployed condition is drenched.When flame made water on the curtain body be warming up to boiling, water promptly was vaporized into water vapour, formed steam fog around the curtain body.The vaporization of water will be taken away heat, make the unlikely intensification of curtain body too high, avoid the curtain body to be burnt out by flame, thereby stop further spreading of fire.In the utility model, the hole for water spraying that is provided with on the fire main can be towards any direction, even because hole for water spraying towards the inwall of gathering sill, the current of ejection finally all can drop onto downwards on the curtain body.Certainly, if make hole for water spraying, then can obtain preferable spray effect directly towards the curtain face of curtain body.Similar with aforementioned existing product, in the utility model, set upper and lower gathering sill can be straight line on its length direction, can also be curve, and is corresponding, and the guide track of above-mentioned gathering sill is straight line or curve.When it was curve, the curtain face of curtain body was also curved when closing, thereby can adapt to the needs of different use occasions.
Compared with the aforementioned existing similar products, because the fire main that side direction type steel steam fog fire curtain of the present utility model directly will offer hole for water spraying is arranged in the last gathering sill of doorframe, thereby shower nozzle can be set no longer separately, simultaneously, the parts such as bend pipe that the shower nozzle rear portion is provided with have also just been saved, both simplify product structure, reduced the manufacturing cost of product again.Be arranged at fire main in the gathering sill and be subjected to the protection of gathering sill, be difficult for laying dust and corrosion, stopping up can not appear in hole for water spraying yet, can guarantee its fire-proof function, and user's line service greatly alleviates.In addition, fire main just need not to be provided with and to install fire proof construction separately when rolling door is installed after being set directly in the last gathering sill, has reduced the installation workload of rolling door.The fire main that is installed in the gathering sill no longer influences the attractive in appearance of user environment, does not also additionally take user's space, causes obstacle can for user's daily operation, allows the user be willing to use this product.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Description of drawings
Fig. 1 is the structural representation of side direction type steel steam fog fire curtain among the embodiment.
Fig. 2 is the A of Fig. 1---the A sectional view.
The specific embodiment
As shown in Figure 1, 2, side direction type steel steam fog fire curtain in the present embodiment is made of doorframe 1, spool 2 and curtain body 3, spool 2 vertically is arranged at a side of doorframe 1, one end of curtain body 3 is fixed on the spool 2, upper side frame 4 and lower frame 5 at doorframe 1 are respectively arranged with gathering sill 6 and following gathering sill 7, the upper side edge of curtain body 3 and lower side embed respectively in the described upper and lower gathering sill 6,7, doorframe 1 is provided with fire main 8, it is characterized in that described fire main 8 is arranged in the gathering sill 6, offers hole for water spraying 9 on the tube wall of this fire main 8.In the present embodiment, the hole for water spraying of offering on the fire main tube wall 9 is towards the curtain face of curtain body 3.For making taking down the exhibits of curtain body comparatively flexible, the upper side edge at the curtain body in this example is provided with the roller 10 that matches with last gathering sill 6.As previously mentioned, during side direction type steel steam fog fire curtain in using the utility model, the user can be connected fire main 8 earlier with water pipe.When breaking out of fire, can close rolling door, utilize curtain body 3 that fiery road envelope is disconnected, open the water supply control valve door simultaneously, allow current enter fire main 8.The current that enter fire main 8 outwards spray through hole for water spraying 9, and the curtain body 3 that is deployed condition is drenched.Under the baking of flame, the water on curtain body 3 surfaces is subjected to thermal evaporation, is vaporized into water vapour, forms steam fog around the curtain body.Because the vaporization of water can be taken away heat, curtain body 3 not reason heats up too high and damages, thereby stops further spreading of fire effectively.
