Definitions

  • a subject of the invention is a roll-up fireproof curtain with a flexible coat, designed for closing a communication hole with linear transport elements in shape of rails, belt conveyor flights, pipelines, cables or other conductors spread crosswise the communication hole and protruding above its foundation.
  • Difficulties related to communication hole protection against possible propagation of fire are commonly known in situation when linear transport elements are spread crosswise the communication hole and protrude above its foundation.
  • well-known lowered or cantilever plate gates are used in general to close suchlike communication holes. If break of a transport line is not possible, but building conditions allow use of a well-known lowered gate, its lower border outline is matched more or less accurately to the transport line profile. When the line elements are situated relatively high above communication hole foundation, a permanent firewall is usually built below this line. Most difficulties, however, occur in the situations when breaking of such a transport line is not possible and, due to the building conditions, only a well-known roll-up gate with a flexible coat can be used to close communication hole.
  • the upper coat border is fastened to a rotational winding shaft that is bearing-mounted in a housing secured to a head of the communication hole to be closed.
  • Side coat borders are located slidingly in permanent vertical groove guides wherein sealing elements well-known from the patent specifications PL 221711 B1 and PL 222492 B1 are found.
  • a transport system having a transport fixing member that configures a transport path for transporting an article and a fire prevention shutter provided to divide the transport path.
  • the fire prevention shutter comprises a fire-proof sheet having an upper end at a position higher than a height of an upper end of the transport fixing member in a state when the shutter main body completely descends.
  • Document JP 2011 219939 A discloses a roll-up fireproof curtain for closing a communication hole, wherein a linear transport element in the shape of a rail is spread crosswise the communication hole and protrudes above its foundation, with permanent vertical groove guides and a flexible coat of a fireproof material that is secured with its upper border to a rotational winding shaft that is bearing-mounted to a head of the communication hole to be closed, wherein the side coat borders are placed slidingly in the permanent vertical groove guides and wherein the curtain is further equipped with a rigid seal plate of a fireproof material that, in the unrolled condition of the coat, is spread longitudinally under the lower border of the coat and adheres to said lower border with its upper surface while the lower surface of the rigid seal plate adheres to the foundation of the communication hole, wherein the rigid seal plate has a lateral open downwards cavity that surrounds the linear transport element protruding above the foundation of the communication hole having a lateral outline matched to the profile of the linear transport element.
  • This fire prevention shutter does not ensures good sealing in each its position.
  • a purpose of the invention is to develop such a roll-up fireproof curtain that ensures tight closing of the communication hole in the event that linear transport elements are spread crosswise the communication hole and protrude above its foundation.
  • the roll-up fireproof curtain has a flexible coat fastened with its upper border to a rotational winding shaft that is bearing-mounted in a housing affixable to a head of the communication hole to be closed.
  • Side coat borders are located slidingly in permanent vertical groove guides inside which there are sealing elements.
  • the curtain according to the invention is characterized in that the curtain is further equipped with a rigid seal plate that, in the unrolled condition of the coat, is spread longitudinally under the lower border of the coat and adheres to the lower border of the coat and adheres to said lower border with its upper surface, while the lower surface of the seal plate adheres to the communication hole foundation, wherein at least one linear transport element is spread crosswise the hole and protrudes above its foundation, whereas the seal plate has at least one lateral open downwards cavity that surrounds the linear transport element protruding above the foundation of the communication hole wherein its lateral outline matches the profile of the linear transport element.
  • the seal plate is fastened to the coat by means of rocking hangers mounted on the plate ends and having a pivotal joint with the lower coat border. Thanks to rotational fastening, the seal plate can be also used when the communication hole head is relatively low. If this is a case, the seal plate, in its upper rest position, is displaced from its natural vertical position to its horizontal position and it adheres to this hole head with its narrow upper surface.
  • the seal plate is placed slidingly in separate groove guides of which lower vertical sections adhere to the coat guides, while the upper sloping sections are deflected outside the communication hole, the seal plate, in its rest position, being situated at the level of the winding shaft housing and, in unrolled coat condition, being situated under lower coat border.
  • the seal plate has a single cavity matched to an outline of a single linear transport element or several cavities formed side by side and matched to outlines of several linear transport elements.
  • a coating of material swelling under temperature increase is formed on the internal circumferential surface of each seal plate cavity.
  • Fig. 1 depicts a front view of the roll-up fireproof curtain in unrolled condition
  • Fig. 2 a horizontal section of the unrolled curtain
  • Fig. 3 a vertical view of the unrolled curtain
  • Fig. 4 - a vertical view of the curtain with the rolled up coat and the seal plate fastened to the coat and oriented vertically towards it
  • Fig. 5 a vertical section of the curtain according to Fig. 4 with the seal plate oriented horizontally
  • Fig. 8 - a front view of the seal plate with two cavities
  • Fig. 9 - a cross-section of the plate according to Fig. 8
  • Fig. 10 an enlarged front view of a single seal plate cavity.
  • the roll-up fireproof curtain according to the invention has a flexible coat 1 of a fireproof material that is secured with its upper border 2 to the rotational winding shaft 3 that is bearing-mounted in the longitudinal housing 4.
  • the housing 4 of the shaft 3 is fastened to the head 5 of the communication hole 6 being closed, formed in the building wall 7.
  • the communication hole 6 is limited below by the horizontal foundation 8, at least one linear transport element 9 being spread crosswise this hole, mounted on the foundation 8 and protruded above its level.
  • the linear transport elements 9 are two running rails 9a.
  • the side borders of the coat 1 are placed slidingly in the permanent vertical groove guides 12, wherein well-known sealing elements, not shown in the drawing, are found.
  • the curtain is equipped with the rigid longitudinal seal plate 13 of fireproof material, that, in unrolled condition of the coat 1, is spread longitudinally under its lower border 10 and adheres to it with its upper surface 14.
  • the lower surface 15 of the seal plate 13 adheres then to the foundation 8.
  • the plate 13 is secured to the coat 1 by means of rocking hangers 16 mounted on the plate ends and having a pivotal joint with the lower border 10 of the coat 1 and allowing rotation of the plate 13 by the angle of 90 degrees. Thanks to such a solution, the plate 13, when in its upper position, can be oriented vertically or horizontally while adhering to the head 5 of the hole 6, and, when in its lower position after the coat 1 is unrolled, it is spread vertically under its lower border 10.
  • the plate 13 When the head 5 of the hole 6 is very low, the plate 13 with its own not shown drive is used and it is placed slidingly in separate groove guides 17 according to Fig. 6 .
  • the lower vertical guide sections 18 adhere to the vertical guides 12 of the coat 1 while the upper sloping sections 19 are deflected outside the hole 6.
  • the seal plate 13 in the rest position is situated on the level of the housing 4 of the shaft 3 and, in unrolled position of the coat 1, it is situated under the lower coat border 10.
  • a horizontal weight 11 in shape of metallic rod is fastened longitudinally on the lower border 10 of the coat 1 to facilitate unrolling the coat 1. As it is shown in Fig.
  • a single lateral open downwards cavity 20 is formed to surround a single linear transport element 9 in shape of pipeline on the foundation 8 and it has its lateral outline matched to this linear element profile.
  • two cavities 20 are formed side by side to surround a pair of running rails 9a on the foundation 8 and their lateral outlines are matched to profiles of these rails.
  • the internal circumferential surface 21 of each cavity 20 is covered with a coating 22 of the material swelling under temperature increase.
  • Smoke detectors not shown in the drawing, respond to smoke occurring in the initial phase of fire, which activates a not shown drive of the winding shaft 3 of the curtain coat 1.
  • the coat 1 unrolls until the seal plate 13 secured to it rests on the foundation 8 of the communication hole 6 to surround the rails 9a or the pipeline 9 located on this foundation with the plate cavities 20 .
  • actuation of smoke detectors results in activation of the not shown drives of the plate 13 and the shaft 3 of the coat 1, wherein activation of the coat 1 drive occurs only when the plate 13 rests on the foundation 8 of the hole 6.
  • the swelling coating 22 on the surfaces 21 of the cavities 20 of the plate 13 increases its volume many times and fills the internal spaces of these cavities while adhering tightly to the surfaces of the rails 9a or the pipeline 9 and to the foundation 8.
