Fire-proof smoke-blocking sliding door system

Abstract

The invention discloses a fire-proof smoke-blocking sliding door system, which comprises an upper compartment, stand columns on two sides, and a fire-proof glass door, wherein the upper compartment isprovided with 18# channel steel and is divided into a water supply cavity and a door machine cavity; a water supply pipe which is evenly provided with a plurality of spray nozzles is arranged in thewater supply cavity; the water supply pipe is in pipeline connection with an outside water source; an induction automatic door machine fixed on the 18# channel steel is arranged in the door machine cavity; a temperature fuse connected with the induction automatic door machine is also arranged in the water supply cavity; the fire-proof glass door comprises fixed door leaves and a movable door leaf;the top of each fixed door leaf is opposite to the 18# channel steel; the side surfaces of the fixed door leaves are fixed on the corresponding stand columns; the bottom of each fixed door leaf is fixed on the ground; and the bottom of the induction automatic door machine is embedded into the bottom of the upper compartment and is in sliding connection with the top of the movable door leaf. The sliding door system gives consideration to the transparency of the sliding door and the fire-proof separation requirement of a fire-proof compartment, and has good fire-proof and smoke-proof performance during fire hazards.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire-proof and smoke-proof sliding door system. Background technique [0002] Existing automatic sliding doors are only used for daily traffic, without fire-resistant glass fans, and the columns and beams of the door body are not designed for fire protection. They do not have fire protection functions and cannot be used for fire separation under fire conditions. The patent application with the application number "201520968200.6" submitted by the applicant on 2015.11.30 and titled "A Sliding Door for Fireproof Partition" solves this problem to a certain extent. The practical value of the door. However, in this design, although the spraying of water from the nozzle can cool down and protect the door operator to a certain extent, the top of the nozzle cannot be protected, and the channel steel itself does not have fire resistance without considering the protection of fire...

AI Technical Summary

Problems solved by technology

However, in this design, although the spraying of water from the nozzle can cool down and protect the door operator to a certain extent, the top of the nozzle cannot be protected, and the channel steel itself does not have fire resistance without considering the protection of fire protection and heat insulation. Performance, will affect the overall fire performance of the fire protection sliding door

The automatic door machine is not clearly set on the surface fire side or the back fire side of the channel steel. The result is: if it is located on the surface fire side, it will directly face high-temperature fire and smoke, and it is easy to burn out; if it is located on the back fire side On the other hand, because the channel steel does not consider fire protection and heat insulation protection, the high temperature generated by the fire will be transmitted to the door operator through the channel steel, and it is also easy to be burned

In addition, because the upper sealing problem between the fixed fan and the movable fan is not considered, after the water from the nozzle is sprayed on the fireproof glass, a small amount of water will splash upwards into the upper compartment, which will cause short-circuit damage to the door operator. All of the above will cause damage to the door operator. Great damage, resulting in failure of the door machine under fire conditions, the sliding door cannot be closed normally, and a complete fire separation cannot be formed, which reduces the reliability of the fireproof sliding door

In addition, due to the gap between the movable fan and the fixed fan in the upper box, there will be a small amount of smoke leakage
