Description

Fireproof rolling shutter door track structure

This invention relates to a fire-proof roller shutter door track structure, in particular, a structure that during a fire can not only prevent the thermal expansion and deformation of the free end edge of the track body and the maintenance cover from causing a clamping gap, but also allow the fire-proof roller shutter fabric to The gap distance between the clamping surfaces tends to be narrowed to reduce the escape of dense smoke, achieve better fire prevention and smoke shielding effects, and prevent the fire-proof rolling curtain cloth from coming out due to gas pressure. It is an innovative designer of the track structure of fire-proof rolling shutter doors that adds practical features to its overall implementation.

According to statistics, there are many high-rise buildings in urban areas. When a fire breaks out in a high-rise area, heat, smoke and fire will spread along the passages between floors. According to fire statistics, it is found that when a fire occurs, it is mostly due to inhalation of too much smoke. The rate of casualties caused by direct fire is relatively low. Therefore, how to prevent thick smoke from flying when a fire breaks out has become an important issue in reducing fire casualties.

Most fire regulations in various countries stipulate that buildings must be equipped with smoke control systems to isolate the heavy smoke produced when a fire occurs. The existing smoke control systems mainly use smoke-proof fire curtains, smoke-proof curtains and other equipment. Generally, smoke-proof systems are used. When the fire curtain or smoke curtain device is not in use, the curtain is rolled up on the cabinet installed on the ceiling. When a fire occurs, the curtain can be activated and hung down from the cabinet to block the spread of thick smoke in the fire; However, there is a gap between the opening of the cabinet for the curtain to fall and the curtain, so that thick smoke can flow into the cabinet through this gap, and then to the other side of the curtain. In addition, there are existing smoke and fireproof curtain devices. After the curtain is lowered, the sides of the curtain often cannot fully fit the track walls on both sides, leaving a large gap between the curtain and the track wall. This also causes thick smoke to flow through the gap. The situation on the other side of the curtain makes the smoke and fireproof curtain device useless.

Therefore, the applicant immediately proposed an announcement No. M516992 on February 11, 2016, "Smoke and Fire Protection Curtain Device Improvement", which mainly includes tracks, rolling curtain fabrics and support units; among them: the track, its There are two corresponding arrangements, forming an accommodation space in the track; the rolling curtain fabric is made of fireproof material, the rolling curtain fabric is arranged between the two rails, and the two ends of the rolling curtain fabric are located on both sides. In the accommodating space of the track; the supporting unit is arranged in the accommodating space of the track. A power source is provided in the supporting unit, and a transmission member is connected to the output end of the power source, so that The power source can drive the transmission member to operate. The transmission member is connected with a screw rod. The outer screw of the screw rod is provided with a guide sleeve. The outer end of the guide sleeve is provided with a smoke shielding strip corresponding to the rolling curtain fabric.

However, although the above-mentioned "smoke and fireproof curtain device improvement" can achieve the expected effect of dense effect, it is also found in its actual operation and use that because it uses the power source of the support unit to drive the guide bushing at the outer end of the screw, The provided smoke shielding strip pushes and presses the rolling curtain fabric on the inner end surface of the track, so that not only when the rotation speed of the power source is out of synchronization, it will cause a gap problem when the rolling curtain fabric is clamped, and the track will also be in place. When heated, it is easy to expand and deform, which will also cause gap problems when the roller curtain fabric is clamped, affecting its fireproof and smoke-shielding effect, leaving room for improvement in its overall structural design.
