Description

Building sprinkler fixing device

The present invention relates to a sprinkler fixing device for a building, and more particularly, the sprinkler body is hidden inside a guide tube while descending a certain height by power applied to an electromagnet coil by a heat sensing signal. It relates to a sprinkler fixing device for a building with improved durability while maintaining stable operability at all times by making it possible to maintain a safe installation state from damage caused by collisions from the outside and contamination caused by contact with dust or moisture.

In general, extinguishing fires occurring in buildings can be divided into extinguishing by fire extinguishers, extinguishing using fire hydrants, extinguishing by fire trucks and firefighters, and extinguishing by sprinkler devices.

Fire extinguishing by fire extinguisher and fire extinguishing by fire hydrant have the advantage of being effective in early extinguishing as the occupants use a fire extinguisher or hydrant to extinguish a fire when a fire occurs in a building. If you cannot use it, it becomes useless.

In addition, firefighting by fire trucks and fire fighters is difficult in the initial stage as it takes the time it takes for fire engines and fire fighters to mobilize to the scene of a fire after a fire occurs and a fire report is received.

On the other hand, each fire brigade attaches great importance to extinguishing the fire in the early stages, and is doing everything possible by setting the goal of extinguishing the fire within 5 to 10 minutes, the so-called golden time of fire. The time required is getting longer.

A fire sprinkler system in a typical building includes a fire extinguishing water tank, a primary pipe including a rising pipe connected to the water reservoir and installed in a pipe duct, and a secondary pipe connected to the primary pipe through an on/off valve and installed in the ceiling; It includes a sprinkler head installed on the secondary pipe and exposed from the ceiling, and in this case, a pressure pump and a pressure tank for pumping water in the water storage tank are installed in the primary pipe.

In the fire sprinkler system of such a building, when a fire is detected by a fire detector, fire extinguishing water is supplied to the first pipe and filled, and the on/off valve is opened to supply and fill the second pipe with fire extinguishing water, but a fuse provided in the sprinkler head In general, watering is done only after it melts and falls off only when it reaches 100℃ or higher.

In this way, the sprinkler detects a fire in the apartment house with a sensor and rapidly sprays water at high pressure to extinguish the fire that occurred inside the house.

Accordingly, a branch pipe that flows into the living room and room of each household is connected to a branch pipe branching from the second pipe installed for each household through the first pipe, and then a sprinkler is installed below the branch pipe.

In the building sprinkler fixing device of Registered Patent No. 2225874 (2021.03.04.), the support pipe can be smoothly fixed through the pipe fixture, and through the sprinkler through-holes formed in the upper plate, the cooler support, and the lower plate. The installation position of the sprinkler can be adjusted or a plurality of sprinklers can be installed.

However, the conventional sprinkler fixing device is a technology that enables the installation position of the sprinkler and the installation of a plurality of sprinklers, but since a plurality of sprinkler through holes are formed, the sprinkler through hole to which the sprinkler is connected does not matter. The part where the sprinkler is not connected has a hole in it, so there is a problem that you have to block them separately.
