A kind of fire extinguishing system and its construction method used in ancient building corridor bridge

Abstract

The invention mainly discloses a fire extinguishing system for a historic building gallery bridge and a construction method of the fire extinguishing system. The fire extinguishing system comprises a pier, a deck, a pavilion, early-warning devices and a fire extinguishing device. The fire extinguishing device comprises a submerged pump, water pumping pipes, a first fire extinguisher and a second fire extinguisher. The submerged pump is arranged in a riverway and connected with the first fire extinguisher and the second fire extinguisher through the water pumping pipes respectively. The first fire extinguisher is installed on the deck, the second fire extinguisher is installed on the pavilion, and the early-warning devices are installed on the deck and the pavilion respectively. Each early-warning device comprises a first temperature sensing piece and a U-shaped cooling pipe. The first temperature sensing pieces are connected with the submerged pump, and the U-shaped cooling pipes are connected with the first fire extinguisher and the second fire extinguisher correspondingly. According to the fire extinguishing system, the early-warning effect can be achieved, the accident rate can be reduced, flame can be extinguished in time and prevented from being extended, injuries and deaths are reduced, effective and omnidirectional stereo protection is achieved for fire control over a historic building, the construction method is simple, no damage is caused to the historic building, and the overall internal structure and appearance of the historic building are kept.

Description

technical field The invention relates to a fire extinguishing system for ancient building bridges and a construction method thereof. Background technique The covered bridge is not only a bridge with a roof, but also can protect the bridge, and at the same time, it can also serve as a shelter from the sun and rain, for people to rest, communicate, gather, etc. It has a very long history and is widely used in Chinese and foreign architecture and garden landscape. The bridge decks and pavilions of existing covered bridges are generally made of wooden products, which have poor fireproof performance. Especially for some old covered bridges, the paint or fire paint peeled off, losing the protection of the wood, making the flammable If the wood is directly exposed to the outside, under the high temperature of the sun or the contact of other sparks, it is very easy to catch fire, causing huge losses to ancient buildings and cultural relics. The fire extinguishing system equipped on...

Problems solved by technology

The bridge decks and pavilions of existing covered bridges are generally made of wooden products, which have poor fireproof performance. Especially for some old covered bridges, the paint or fire paint peeled off, losing the protection of the wood, making the flammable The wood is directly exposed to the outside, and it is very easy to catch fire under the high temperature of the sun or the contact of other sparks, causing huge losses to ancient buildings and cultural relics.

The fire extinguishing system equipped on the corridor bridge is generally a dry powder fire extinguisher, which needs to be manually obtained for fire extinguishing. It takes a lot of time from knowing the fire to running to the corridor bridge to extinguish the fire. The fire is easy to expand rapidly during this period, causing major accidents , and in the state of fierce fire, the fire extinguishing speed is slow and difficult to extinguish, it is difficult to extinguish the fire on the top floor, the safety is low, and it is easy to cause injury to firefighters and cause casualties
