Description

With pull-proof smoke curtain

The invention relates to fire fighting equipment and, more particularly, to a smoke barrier.

According to the general fire, when the smoke will use various pipes to smash around, it is easy to form a chimney effect, resulting in a significant loss of personnel or property.

Therefore, when constructing fire-fighting facilities, buildings will use fire-proof and smoke-proof rolls so that they can be concealed and hidden in normal times. When a fire or smoke is present, it can be lowered to block the spread of fire. And the smoke of the smoke. However, such a tensile barrier is not smooth, fast, and prone to gaps, resulting in a significant reduction in fire and smoke prevention.

It can be seen that there are still many shortcomings in the above-mentioned household items, which is not a good designer and needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional facilities, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in researching and developing this piece of anti-sliding smoke curtain.

The object of the present invention is to provide a stretch-proof smoke curtain, which has the advantages of strong wind pressure resistance and strong crack resistance.

A second object of the present invention is to provide a stretch-proof smoke curtain having a long-diameter sliding track having friction resistance, and when the tensile-resistant smoke curtains are sewn together to form a knot sliding therebetween, the stitching The wire has the effect of suppressing friction resistance.

Another object of the present invention is to provide a tensile barrier having mechanical properties such as tensile strength, breaking strength, etc. and thickness which can be adjusted over a wide range.

The anti-sliding smoke curtain which can achieve the above object of the invention comprises: a pair of long rail members, which are long-diameter sliding lanes, wherein the long-diameter sliding rails have a relationship with the long rail members a second metal plate having a relative bending property, wherein the two metal plates have a taxiway width, and the first sliding track is formed by one of the two metal plates of each of the long rail members; the second taxiway, Formed on the other of the two metal plates of each of the long rail members; a tensile barrier, the two end surfaces of which extend into the first taxiway and the second taxiway and are folded, and are stitched by low elongation The wire sutures at least two layers of tensile barriers into a knot, and the thickness of the tensile barrier is less than the width of the taxiway of the two taxiways, and the knot extends to an open side with respect to the knot on the bend side. When the tensile barrier is under pressure, the knot and the open side The ends jointly pull the edge of one metal plate against the inner side of the other metal plate, so that the knot of the tensile flame shield and the open side end are used to seal the taxiway to achieve airtightness, so that the two taxiways are under pressure. In the state, a sliding contact path having tensile force and pull-out resistance is formed. Thereby, when the retractor generates the pre-force of release, the anti-sliding smoke curtain moves down along the taxiway; thereby preventing the flame or the smoke from entering the elevator door, thereby reducing the fire and The speed of smoke spreads in order to fight for the escape time of every second.

The top end of the tensile barrier 2 is coupled to the retractor 3, and is retractable by the operation of the retractor 3 (Fig. 10 shows that the anti-sliding hood has an open side end. 12 shows that the tensile barrier has two open side ends.) or is released downwards (Figure 11 shows that the tensile barrier has an open side end. Figure 13 shows that the tensile barrier has two open side ends.), And the two sides of the tensile barrier 2 are respectively passed through the taxiways of the long rail members 1 so that the tensile barrier 2 can be moved up or down when released. The long rail member 1 is slipped to maintain smoothness during slippage. The tensile barrier 2 is formed with a knot 21 formed on the taxiway width H of the taxiway. The knot 21 is folded and stitched to the taxiway width H of the tensile barrier 2 The outer diameter of the knot 21 is made larger than the diameter of the taxiway to prevent the tensile barrier 2 from being detached from the long rail member 1.

The weight members 4 are respectively coupled to the two taxiway widths H of the tensile barrier 2 with a predetermined weight, so that the tensile barrier 2 is released when being released by the retractor 3 It can increase the speed of the downward movement by its weight to achieve the effect of rapid action.
