Description

Fire piping installation structure {Fire piping structure for building}

The present invention relates to a fire extinguishing piping installation structure, and more particularly, by a plurality of sprinklers respectively provided in a main pipe and a support pipe from a branch pipe provided at regular intervals, in the event of a fire, the spray range of fire extinguishing water is expanded and concentrated to the maximum extent to extinguish the fire. It relates to a firefighting piping installation structure that can maximize efficiency.

In general, a building is provided with a fire extinguishing water supply pipe through which water is transported through a pipe connected to a fire extinguishing tank.

These piping is installed to be connected to various fire extinguishing facilities installed in the building, so that water can be sprayed to the fire extinguishing facility when a fire occurs in the building.

At this time, the fire extinguishing facility connected to the pipe to spray water into the building is configured to form various forms, but it is usually installed on the ceiling of the building to spray water supplied through the pipe into the room. Sprinkler is being used a lot.

Such a sprinkler is installed under the ceiling of a building as specified through the sprinkler head fixing structure of Registered Utility Model No. 0329043 (2003.09.25.) and the firefighting pipe installation structure of Registered Patent No. 2359476 (2022.02.03.) When it detects a fire occurring indoors, water is automatically sprayed to the place where the fire occurs.

However, in the case of the former, sprinklers are not installed from the beginning during the construction of the building, or even if sprinklers are installed, there are cases where they fail to function properly due to deterioration. It is easy to install and use the sprinkler on the ceiling.

However, the fire piping in the prior art connects the sprinkler to the connecting pipe and a separate sprinkler fixing device, and these sprinkler fixing devices must be fixed to the ceiling, respectively, but the connection structure between the sprinkler and the pipe is too complicated. There are problems with construction.
