Abstract

PURPOSE: To provide an inexpensive fire extinguishing device employing a pipeline for floor heating device and a fire extinguishing device commonly, in a building wherein the floor heating device is applied. CONSTITUTION: The branch pipes 20, 21, 22 of a lattice pipeline 12 for a floor heating device are connected to sprinklers 31, 32, 33, which are provided at the ceiling 30 of an underfloor, through pipelines 23, 24, 25.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fire extinguisher, and more particularly to an inexpensive fire extinguisher in which piping equipment is shared with a floor heating system.

[0002]

2. Description of the Related Art In buildings where an unspecified number of people enter and leave,
Sprinklers must be installed as fire extinguishing equipment. In order to reduce the cost of piping equipment for this sprinkler, a joint use of the piping for the floor heating device and the piping for the sprinkler has been proposed, for example, in Japanese Patent Application Laid-Open No. 4-261672. According to this device, the center heat pump unit is provided outside the building, the primary side feed pipe is connected to the center heat pump unit, and the secondary side feed pipe is connected to each floor from the primary side feed pipe. The indoor heat pump unit and the sprinkler are connected to the secondary side piping.

[0003]

In the above-mentioned prior art, the heat pump unit is used for the cooling and heating equipment of the building. By the way, no consideration is given to a floor heating device for heating the floor by burying pipes in a grid pattern on the floor of the floor of the building as heating equipment and circulating hot water directly to the pipes.

It is an object of the present invention to provide an inexpensive fire extinguisher in which a floor heating device and a pipe for the fire extinguishing equipment are shared in a building suitable for the floor heating device as the heating equipment.

[0005]

The object of the present invention is to provide a floor heating device for heating the floor by burying pipes in a grid pattern on the floor of a building and circulating hot water directly to the pipes. This is achieved by connecting a pipe from an arbitrary place of the floor heating system to a sprinkler provided on the ceiling of the lower floor of the floor.

[0006]

According to the present invention, when the sprinkler is installed at a necessary place, since the pipe for the floor heating device is provided just above the sprinkler, the pipe can be connected with a short pipe, and the equipment cost is low. A fire extinguisher can be constructed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be explained.

1 and 2 are a front view and a plan view of one floor of a building provided with a fire extinguisher according to the present invention.

In the figure, reference numeral 1 is a main pipe connected to an elevated water tank provided on the roof of a building (not shown), which is divided into a technique pipe 3 by a branch pipe 2, and the technique pipe 3 is provided with a heating device 10 via a manual valve 4. It is connected to the. Under the floor 11, a lattice-shaped lattice pipe 12 is laid, and the hot water warmed by the heating device 10 warms the floor 11 from the feed pipe 13 through the lattice pipe 12 and the return pipe 14 to heat the heating device. Returning to 10, hot water circulates. Reference numerals 20, 21, and 22 are branch pipes provided in the lattice pipe 12, and from the branch pipes 20 to 22, the technique pipes 23 to 2 are provided.
It is connected to the sprinklers 30 to 31 provided on the ceiling 30 one floor below through 5. 5 is a branch pipe 6 of the main pipe 1
An automatic valve inserted between the feed pipe 13 and the feed pipe 13 is a pressure gauge that operates when the pressure of the hot water in the grid pipe 12 becomes a set value or less. When the pressure gauge 7 operates, the automatic valve 5 operates. It is configured to open.

Next, the operation of this embodiment will be described.

To perform floor heating, first, the manual valve 4 is opened, water is supplied from the main pipe 1 into the lattice pipe 12, and the manual valve 4 is closed. Next, the water in the heating device 10 is turned into hot water by a heater (not shown), and a pump (not shown) is driven,
The hot water is circulated through the heating device 10, the feed pipe 13, the lattice pipe 12, the return pipe 14, and the heating device 10 to heat the floor 11.

It is assumed that a fire broke out on the lower floor and the sprinkler 31 was activated. As a result, grid piping 1
Since the hot water in 2 spouts into the room at once, the grid piping 12
The pressure of the hot water in the inside suddenly drops, and the pressure gauge 7 operates.
Then, the automatic valve 5 is opened, water is supplied from the main pipe 1, and the fire is extinguished.

As described above, even if the sprinklers 31 to 33 are installed at arbitrary places on the ceiling, the sprinklers 31 to 33 can be connected with a pipe shorter than the lattice pipe 12.

Since the other floors have the same structure, the description thereof will be omitted.

[0015]

As described above, according to the present invention, an inexpensive fire extinguisher can be provided because it can be connected to a sprinkler on the ceiling on the lower floor from any place of the lattice piping of the floor heating system with a short piping. Can be provided.
