Abstract

PURPOSE:To remove heat to be applied to columns and beams, and prevent fire accidents from being occurred by arranging water channels for feeding cooling water into the columns and beams of an architectural structure, and by injecting water into the water channels at the time of fire. CONSTITUTION:The internal sections of the steel pipes 11 of the columns and beams of a structure are provided with can-shaped parting walls 13 which is sealed with gas, and water channels 12 arranged to be hollow in the length directions are formed. The can-shaped parting walls 13 are formed of heat- resisting and corrosion-resisting material. Besides, the upper sections of the water chennels 12 are provided with relief valves for relieving residual gas in the water channels and regulating water pressure, and the lower sections are provided with discharge ports, respectively. When a fire accident occurs on the structure, then cooling water to be fed from feed water pipes to the water channels 12 of the internal sections of the steel pipes 11 is injected from water injecting ports, and heat to be applied to the columns and beams is removed, and the cooling water discharged from the discharge ports is splashed, and is used for extinguishing the fire, and the structurte is prevented from being burnt extensively.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel material having water channels for passing cooling water inside columns and beams of a building structure.

0002

[Prior Art] Conventionally, building structures composed of steel frames were
To protect the columns and beams from the heat of the fire, they have been covered with fireproof boats and rock wool.

0003

According to the conventional technology, when high-temperature heat is applied to the columns and beams of high-rise buildings, which are difficult to digest, the strength of the columns and beams is significantly reduced. In addition, in the case of a cable fire in the interior of a building or inside a wall, or if office equipment, desks, or other furniture made of organic matter gasifies and burns in high-temperature conditions, conventional fire extinguishing equipment cannot be used. It is enough.

[0004] In such a situation, if secondary forces such as wind power or earthquakes act on the building, it may cause a major disaster.

[0005] Rock wool, which is often used as a fireproof covering material, contains small amounts of asbestos in most products, which has a great negative impact on the human body and the environment, especially during construction and renovation.

[0006] When fireproofing and soundproofing work is carried out on the beams and walls inside an elevator tower using fireproof covering materials such as rock wool, dust containing asbestos is scattered due to the wind pressure generated when the elevator operates. , there are major health and safety issues.

[0007]

[Means for Solving the Problems] According to the present invention, an architectural structure is constructed of columns having water channels for passing cooling water inside the columns and beams.

[0008]

[Function] When a fire breaks out in the building, the water channels 2 and 1 installed inside the columns and beams of the H-shaped steel 1 and steel pipes 11 will allow cooling water to be sent from the sprinkler water pipes and dedicated water pipes.
2 to remove the heat applied to the columns and beams, and the cooling water discharged from the outlets 5 and 15 is used to extinguish the fire to prevent the spread of the fire.

[0009] Another possible application is to beams in cabins of ships, etc.

[Embodiment] FIG. 1 is a cross-sectional view of one embodiment of the present invention, in which a hollow penetrating waterway (2) is formed and an H-shaped steel (1) is formed.
When the flange is exposed to heat from the outside, cooling water is poured into the hollow water channel (2) to cool the flange.

The embodiment shown in FIG. 2 is similar to that shown in FIG. 1, in which a gas-tight can-shaped partition (13) is provided inside the steel pipe (11) to form a water channel (12).

The embodiment shown in FIG. 3 is an example of a combination of the embodiments shown in FIG.
).

The steel pipe (11) constituting the column is provided with a can-shaped partition wall (13) that seals gas inside, and a water channel (12) is provided inside.
), with a relief valve (7) at the top and a discharge port (7) at the bottom.
15) is formed. The relief valve (7) releases gas remaining in the waterway and adjusts the water pressure.

The H-shaped steel (1) forming the beam forms a hollow waterway (2) that penetrates inside, a discharge port (5) is provided in the center, and check valves (6) are provided at both ends. ) are arranged to form a beam. A diaphragm connected to the beam is provided with a water inlet (4) connected to a water supply pipe, forming a column. Further, the can-shaped partition wall (13) and the check valve (6) are made of heat-resistant and corrosion-resistant materials, and the check valve (6) is made of a material with a discharge port (
It is fixed so that it opens in the direction of 5).

[0015] When a fire breaks out in the building, the column constructed with such a combination takes in cooling water sent from the water supply pipe from the water inlet (4) and directs it to the water channel (12) inside the steel pipe (11). Water is supplied and sprayed from the outlet (15) to extinguish fires. On the other hand, water is sent to the waterways (2) of the plurality of opposing H-beams (1) that make up the beam, and is sprayed from the outlet (5) to extinguish the fire.

[0016] Furthermore, by adopting a water supply method depending on the situation of the fire location, a plurality of backup functions become possible.

[0017]

[Effects of the Invention] As explained above, when a fire is detected in a building, the water-cooled column of the present invention directs cooling water sent from the sprinkler water supply pipe and the dedicated water supply pipe to the inside of the column and beam. Water is injected into the hollow canals provided to remove the heat applied to the columns and beams, and the cooling water discharged from the outlet is used to extinguish fires, especially in the ceilings and inside walls where sprinkler water cannot reach. In addition to helping extinguish fires and preventing the spread of fire,
It has the advantage of protecting human life and buildings from fire. Furthermore, by avoiding the use of rock wool, which is often used as a fireproof covering material, there is no need to worry about any negative effects on the human body or the environment.
