Description

The air-cured structure improvement of the curtain box of the fireproof roll door

This creation relates to a kind of fire curtain roll that can suppress the spread of fire and respond to the formation of high temperature hot air in the fire field to ensure the spread of fire and prevent the effect from functioning and reliability. The air curtain structure of the curtain box is improved.

According to the urban population density, in order to solve the needs of living and office, urban buildings can only develop towards high floors, but high floors have unresolved bottlenecks in public safety, especially in the event of a fire. The range that can be reached due to the fire truck ladder also has its limits. For this reason, in modern building planning, the safety of fire prevention must be taken into account; especially for large-area public buildings, fire-proof curtains are mostly used as fire-proof partitions. The main reason is that fire-proof curtains are easy to control, and It will affect the vision of the space and facilitate the access of people, goods and vehicles. When a fire occurs, it can be combined with the detection of the automatic sensing system to timely release the fire curtain to prevent the spread of the fire source, effectively ensuring the safe evacuation of personnel and reducing the fire damage.

However, the general configuration of the fireproof curtain is provided in a magazine of a roll box, and a reel is wound on the reel, and the fire reel is wound on the reel, and the fire reel is taken from the room when the fire occurs. The fire curtain is placed in the opening to block the spread of the fire; however, in actual use, after the fire curtain is lowered, there is a large gap between the opening and the two sides of the fire curtain, so that the hot air flow will be self-contained. One side of the fireproof curtain flows into the chamber and then flows to the fire On the other side of the rolling screen, due to the effect of the concentrated flow of hot air, the safe area where fire has not occurred is exposed to the crisis of flashing hot air at any time; the new type of fireproof box airtight structure, No. M448558, is used in Taiwan. Patent case or No. M448559 "Improvement of air-tight structure of fire-proof coil box" Taiwan's new patent case, although both sides of the curtain piercing or on the fire-proof screen are provided with airtight strips to seal the gap between them, blocking The hot airflow in the fire zone enters the coil box to prevent the fire from spreading. The airtight strip is only fixed at one end, and then attached to the side of the box or the side of the fire curtain by the unfixed natural end deformation elastic force. The weak sealing curtain is not enough to withstand the forced extrusion of the hot air flow, resulting in airtight failure; that is, when the entire fire curtain is blocked by the hot air or pressed by the hot air current, most of the hot air flow As a result of the concentration of energy to the opening of the curtain, only the gap between the natural opening of the airtight strip and the soft end of the curtain is closed, and the airtight effect is not reliable, and it is necessary to re-innovate or improve the structure.

The main purpose of this creation is to provide a kind of air-tight structure improvement of the curtain box curtain of the fire-proof roll door, which is provided with a reel in a box of a curtain box, and an airtight door rail on each side of the bottom of the box. a repellent fireproof curtain is wound on the reel, and a weight base movable along the airtight door rail is arranged between the two airtight door rails; one end of the smokeproof fireproof curtain is from the box The bottom end of the outlet portion extends out of the box and is connected to the weight base, and the two sides are respectively embedded in the airtight door rail to form airtightness; the improvement is that the outlet portion of the rolling box is in a hole The two sides of the mouth are respectively provided with a heat-resistant soft rubber elastic body which is allowed to compress and deform, and the two soft rubber elastic bodies respectively have an arc-shaped elastic portion which is extended at the orifice. The upper edge is closely attached to the side surface of the smoke-proof fireproof curtain to form an airtightness; in normal times, the reel is subjected to the winding action of the smoke-proof fireproof curtain, and the curved elastic portion of the two soft rubber elastic bodies Fireproof curtain Upward pulling pulls a responsive shape change, so that the smokeproof fireproof curtain can be pulled up and the door base is raised to a high position along the airtight door rail to open the door; when the fire occurs, the reel is fireproof The revolving motion of the reeling of the soft curtain elastic body is subjected to a shape change in response to the downward movement of the smoke-proof fireproof fabric curtain, which can be lowered by the counterweight base along the airtight door rail In the process of positioning to the ground, the smoke-proof fire curtain is pulled out from the exit of the curtain box, and the fire alarm closing action of the smoke-proof fire curtain is completed; when the fire-proof curtain is laid down, the two soft rubber elastomers are The arc-shaped elastic portions are pressed against each other to maintain a gas-tight state on one side of the cloth of the smoke-proof fireproof curtain, and the hot air flow generated by the fire side of the side of the smoke-proof fireproof curtain can be obtained from the opening of the outlet portion. It is closed by two soft rubber elastomers to prevent hot air from entering the box of the rolling box, preventing the hot air from flowing to the other side to stop the fire from spreading; and the hot air generated by the fire, even for the fireproof curtain Compression has caused the arc of the cloth to expand or under In the case, the arc-shaped shrapnel portion of the two soft rubber elastomers is pulled, and the shape thereof is reacted with deformation to continue to be kept airtight on the cloth surface of the smoke-proof fireproof curtain, ensuring that the fire spreads to prevent the effect from functioning normally, thereby improving the fire prevention. Reliability of the ability.

The second purpose of the present invention is to provide an improved airtight structure of a curtain box curtain of a fireproof roll door, wherein the two soft rubber elastic bodies are respectively a heat-resistant soft rubber sheet bent and each fixed at a fixed position. The D-shaped soft rubber elastic body is fixed on the seat, and a hollow arc-shaped elastic portion which is pressed against the cloth surface of the smoke-proof fireproof curtain is respectively formed, and the hollow curved elastic portion is covered. The smoke fireproof curtain moves up or down and pulls, and will flexibly respond to or respond to the pulling force with a certain degree of elastic deformation ability, so that the winding or lowering process of the smokeproof fireproof curtain can complete the opening with a low damping type. Or closing the door; and the bending ends of the soft rubber elastic body are on the fixing base, and each of the soft rubber elastic bodies is provided with a clip to fix the two ends of the soft rubber elastic body on the fixing seat, so that the D shape The soft rubber elastomer is at the exit of the rolling box, and the fixing seat is well supported and fixed for a long time.
