Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a refueling apparatus installed in a so-called gasoline station for refueling automobiles, motorcycles and the like with fuel such as gasoline.
[0002]
[Prior art]
Among the oil supply devices installed in the gasoline station, the fixed oil supply device is installed on the island installed on the ground. The oil supply pump and flow meter are installed in the oil supply pipe that rises from the underground oil storage tank inside the housing. In addition, a control device or the like is incorporated, an oil supply amount indicator is provided on the outer surface, and an oil supply hose provided with an oil supply nozzle at the tip is attached to the outside.
[0003]
As shown in FIG. 4, the oil supply device is configured such that a housing is erected on the island 1, and the housing is provided with a bed 3 as an installation base at the lower end of the housing body 2. It is fixed with anchor bolts 4 embedded in the island 1.
[0004]
Reference numeral 5 denotes a pit formed in the island 1. In this pit 5, an oil supply pipe 6 a rising from an underground oil storage tank is connected to an oil supply pipe 6 b into the housing body 2, and a flexible joint 7 made of bellows or the like is used. It is done. In the figure, 8 is a waterproof mortar that forms the inner periphery of the pit 5.
[0005]
[Problems to be solved by the invention]
However, when a strong impact is applied to the housing body 2 due to an earthquake or a vehicle collision, the housing body 2 tilts and a strong force acts on the fixing portion between the anchor bolt 4 and the bed 3. The surrounding concrete may be destroyed, the anchor bolt 4 may come off, and the housing body 2 may fall. Note that although the housing body 2 falls over the flexible joint 7, it cannot be handled in this portion, leading to oil leakage and risk of a disaster such as a fire.
[0006]
An object of the present invention is to provide an oil supply device that can eliminate the inconveniences of the conventional examples, and that can be easily prevented from overturning even when subjected to an impact such as an earthquake simply by adding an inexpensive structure. .
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an oil supply apparatus in which a housing main body is installed on an island via a bed, and the bed is a steel pit with a steel rectangular frame, and has an outward flange at the upper end. The steel pit is used as a formwork, the steel pit is buried as it is after the concrete is hardened, and the fall prevention member embedded in the island is fastened with an anchor bolt so that the upper end of the steel pit is exposed. The gist is to install the housing body on the island through a bed by fastening with bolts .
[0008]
According to the first aspect of the present invention, the fall prevention member is coupled to the bed, and the fall prevention member prevents the housing body from easily falling over.
[0009]
In addition to the above action, the fall prevention member is a steel pit with a steel rectangular frame, so that this steel pit can be used as a formwork for pit formation. Just bury and kill, and join the bet to the upper end that appears on the island. Moreover, since the steel pit is embedded in the island, the housing body can be firmly supported even if it is not large.
[0010]
If a bed is placed on the outward flange at the upper end and both are fastened with anchor bolts, a more stable support is possible.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partially cutaway front view showing a first embodiment of a fueling device of the present invention, in which the same components as those in FIG. 4 showing the conventional example are given the same reference numerals.
[0012]
The oil supply device is fixed on the ground, and is provided with a bed 3 as an installation base at the lower end of a housing body 2 erected on the island 1.
[0013]
In the present invention, a steel pit 9 made of a steel rectangular frame is used as a mold to form the pit 5 in the island 1, and the steel pit 9 is buried as it is after the concrete is hardened, and its upper end is exposed. Embed in the island 1 so that it comes out. The anchor bolt 4 is engaged with the steel pit 9 when the steel pit 9 is installed in this manner, and is set so as to protrude on the surface of the island 1 from the inside of the concrete to be hardened.
[0014]
In the pit 5, the oil supply pipe 6 a rising from the underground oil storage tank is connected to the oil supply pipe 6 b into the housing body 2, and a flexible joint 7 made of bellows or the like is used. In the figure, 8 is a waterproof mortar laid on the bottom of the pit 5, that is, the bottom of the steel pit 9. The example of FIG. 1 is an example in which there are two systems of oil supply pipes, and 14 in the figure is an oil supply amount indicator. The illustration of the oiling nozzle and the oiling hose is omitted.
[0015]
As shown in FIG. 2, the steel pit 9 has outward flanges 9a and 9b at the upper and lower ends, and the outer flange 9a at the upper end has a bolt insertion hole 10 for setting the anchor bolt 4. Set up.
[0016]
Using this steel pit 9 as a fall prevention member, the bed 3 is placed on the outward flange 9 a that appears on the upper surface of the island 1, and both are fastened by the anchor bolt 4.
[0017]
The bet 3 and the housing body 2 are fastened with bolts 13 so that the housing body 2 is installed on the island 1 via the bed 3.
[0018]
The steel pit 9 is embedded in the island 1, and even if the housing body 2 is about to fall due to an earthquake or other impact, the steel pit 9 is supported, so that the fall can be prevented. The steel pit 9 may not have an outward flange 9b at the lower end.
[0019]
FIG. 3 shows a second embodiment of the present invention, in which a steel substrate 11 is laid on the island 1, and the bed 3 is placed thereon using the steel substrate 11 as a fall prevention member. The main body 2 was placed on the island 1 through the bed 3.
[0020]
Bolt insertion holes 12 are formed in the steel substrate 11, and the steel substrate 11 and the bed 3 are fastened to each other by the anchor bolts 4 through the bolt insertion holes 12.
[0021]
In the case of this embodiment, the steel substrate 11 is installed in a large area with respect to the island 1, and the steel substrate 11 supports the housing body 2, thereby preventing the housing body 2 from falling.
[0022]
【The invention's effect】
As described above, the fueling device of the present invention can be easily prevented from falling even when subjected to an impact such as an earthquake simply by adding an inexpensive structure, and can improve safety. is there.
