BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. The same parts as those in the conventional example are designated by the same reference numerals. FIG. 2 is a cross-sectional view showing a fire wall of a gas station according to the embodiment of the present invention, and FIG. 3 is A of FIG.
-A sectional drawing, FIG. 4 is a perspective view which shows the upper part of FIG.

The basic construction of the embodiment of the fire wall 1 of the gas station of the present invention will be described. A plurality of pairs of fire plates 1a, 1b facing each other inside and outside are horizontally connected along the boundary of the compartment. It stands upright. Further, a water intrusion prevention cap 1c extending in the horizontal direction is fitted on the upper open ends of the plurality of pairs of fire protection plates 1a and 1b. In addition, in a part in the horizontal direction between the lower end of the cap 1c and the outer surfaces of the plurality of pairs of fireproof plates 1a and 1b, a gap that allows the space sandwiched between the fireproof plates 1a and 1b to communicate with the outside air. S1 is formed.

Further, a gap S2 is formed between the lower end of the cap 1c and the upper open end of the fireproof plates 1a and 1b, and the gap S2 is sandwiched between a plurality of pairs of fireproof plates 1a and 1b. The air in the open space is configured to communicate with the outside air. In addition, the plurality of pairs of fire protection plates 1a and 1b are shown in
As shown in (1), it is preferable to stand on the concrete base 2 that is set up along the section for rust prevention.

The fireproof plates 1a and 1b may be flat plates made of steel, but as shown in FIG. 3, a steel plate having a trapezoidal cross section and a corrugated plate made of a steel plate are preferable in terms of price and strength. The water intrusion prevention cap 1c includes the fire protection plates 1a, 1
The cross section is elliptical arc (C
In addition, the lower part is opened to a width approximately equal to the distance between the outer surfaces of the fire protection plates 1a, 1b, and is elastic like springs so as to be in close contact with the outer surfaces of the fire protection plates 1a, 1b when fitted. Is given.

As a result, the lower end of the cap 1c and the fireproof plates 1a and 1b having the ridges and ridges are formed so that the space sandwiched between the fireproof plates 1a and 1b communicates with the outside air when the cap 1c is fitted on the outside. A gap S1 is formed between the outer surface of the fire prevention plate 1a and the outer surface of the fire prevention plate 1b, and a gap S2 is formed between the upper open end of the fire protection plates 1a and 1b. A cap holder H that supports the cap 1c from below is provided on the outer surfaces of the fireproof plates 1a and 1b.

In the construction, first, the ground is dug shallowly, and a split stone 51 is laid on the bottom of the formed recess. Furthermore, a concrete foundation 52 having a thickness of about 150 mm is provided on the split stone 51, and a concrete floor 53 is provided on the ground.
Is stretched. Next, the base 2 made of concrete is erected on the floor 53 along the boundary. Further, a column 1e made of shaped steel is erected on the base 2 at appropriate intervals in the horizontal direction, and a plurality of horizontal beams 1f made of shaped steel are laid vertically and horizontally on the column 1e. As a result, the support frame 1d is formed. After that, as described above, a plurality of pairs of fireproof plates 1a and 1b are stretched on the support frame 1d in a horizontally connected state via bolts B, and the plurality of pairs of fireproof plates 1a and 1b are stretched.
A water intrusion prevention cap 1c is fitted on the upper open ends of a and 1b.

The operation will be described. Since the air in the space sandwiched by the plurality of pairs of fire protection plates 1a and 1b communicates with the outside air through the gaps S1 and S2, the fire protection plates 1a and 1b are connected.
When the air in b is heated by solar radiation, flame, etc. and expands, it is released to the outside through the gaps S1 and S2, so that there is no trouble such as blown off of the cap 1c. Moreover, since the lower end of the fireproof plates 1a and 1b provided on the base 2 is not in contact with the ground (floor surface), rust due to contact with water is unlikely to occur and is excellent in durability. .

According to this embodiment, the cross section of the water intrusion prevention cap 1c has an elliptic arc shape (a U-shape) and the gap S1,
Although S2 is formed, the cross-sectional shape is not particularly limited to this, and may have a U-shaped cross section as shown in FIG. 5, for example. According to this, it is not necessary to make the cap 1c particularly spring-like elasticity. In addition, as shown in FIG.
The U-shaped cap 1c may be externally fitted deeply without providing the cap holding portion H on the outer surface of 1b. In this case, it is necessary to form the communication holes P and Q in the fireproof plates 1a and 1b and the cap 1c instead of the gaps.

[0019]

As described above, according to the present invention , most of the members can be mass-produced in a factory, so that the cost is low. In addition, the assembly work is easy and the construction period is short. Moreover, since the space between the fireproof plates is hollow, it is lighter in weight and lighter in weight than the concrete block made of the conventional example, so that the foundation becomes smaller and the cost is reduced as a whole.

Fire protection plates are installed along the boundaries of the compartment.
The one installed upright on a concrete base that has been reinforced will cause a slight increase in cost, but since the lower end of the fire protection plate is not in contact with the ground (floor surface), it will not rust due to contact with water such as inundation. It does not easily occur and has excellent durability.
