Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to pavements applied in service stations where combustible materials are handled.

Flammable materials at gas stations, (flammable materials are strictly prohibited in places such as gas stations, etc.)
This is very dangerous as static electricity builds up or static electricity is generated during refueling operations, which can cause sparks.

For this purpose, a ground wire is connected to the refueling nozzle (to remove static electricity, for example, the refueling L1 of a car's fuel tank)
Not suitable if the part is made of non-electrical plastic (
・Even if the nozzle is made of metal, static electricity cannot be removed if the nozzle is separated from the lubrication point. YoIko7/-
The wire runs through the refueling hose, and in some cases it breaks and no longer functions as a ground wire.

Generally, the grounds of gas stations are paved with 11 concrete 1~, and since concrete 1~ itself has poor conductivity, water is sprinkled on it to increase the conductivity in order to dissipate the static electricity generated during automatic operation. However, the work of sprinkling water is troublesome, and the conductivity may vary depending on the degree of drying and drying, which is not preferable.

Therefore, it is an object of the present invention to provide a conductive pavement that can remove static electricity from automobiles and human bodies located on the pavement surface by forming a conductive pavement surface in areas where materials are handled. There is something to do.

According to the present invention, by laying a conductive member on the uppermost surface of the normal line in a place where combustible materials are handled, static electricity stored in automobiles and human bodies is reliably released to the ground, and ignition due to static electricity sparks is prevented. -It's like it's on.

According to an embodiment of the present invention, a conductive member containing an epoxy resin as a binder, carbon powder or aluminum powder as a conductive material, and crushed sand as an extender is used.

Therefore, a pavement with excellent conductivity can be obtained at relatively low cost.

Furthermore, when carrying out the present invention, if a metal wire such as a wire mesh is disposed in the conductive member and the metal wire is connected to the ground, the effect of dissipating static electricity can be achieved within the layer. Roughly speaking, as an embodiment of the present invention, a conductive member is installed in the floor pavement and extends to and comes into contact with the reinforcing bars, thereby further improving the effect of dissipating static electricity. Also, in this way, the physical contact of the conductive member with respect to the floor 1 can be avoided.1. .

Embodiments of the present invention will be described below with reference to the attached drawings. Fig. 1 shows a fueling station A that implements the present invention with 1kJ, and its canopy C has hanging type fueling MIS1, S2, and S2.

When carrying out the present invention, the site [site]) may be turned into a conductive pavement surface, but the ranges X1, X2, x3, ×4, and .

FIG. 2 is a sectional view of the conductive #AS11' surface. 1 is a floor paving made of reinforcing bars 1~ laid on the ground, and a conductive member 2' is placed on the upper surface of this flooring device for about 10+++n+
It is laid with a thickness of . The conductive member 2 is made of conductive resin Lrutal, which is a mixture of epoxy resin, carbon powder, :&a aluminum powder, and sand at a ratio of φi (approximately 10:1:60).

With this structure, the static electricity stored in the car stopped at the refueling work location passes from the auto body through the tie V, and then from the conductive member 2 through the ground wire, such as the reinforcing bar of the flooring equipment, and into the ground. flows to

As described above, by simply laying the '4 electric bamboo shrine on reinforced concrete', the charged object on the conductive member can be sufficiently grounded. However, in order to further ensure the performance of the first step, the embodiments described below can also be adopted.

In the second embodiment shown in FIG.
Wire mesh 3 is laid at intervals of M, and the conductive member 2 is spread over the wire mesh 3 by approximately 5++ m. The wire mesh 3 is buried in this way, and the ground wire 4+ is connected to the wire mesh 3 to form a conductive paved surface. do.

In this second embodiment, even if the normal device has extremely poor conductivity, it is possible to fully exhibit its earthing function.

FIG. 4 shows a third embodiment of the present invention. When laying the conductive member 2, first, a metal wire 5, for example, a pin, is driven into contact with the reinforcing bar 6 in the normal line device. , the normal line is made to protrude 3.about.6u+ on the 44th plane in the device, and then the conductive portion 442 is placed about 10IIRI.

In the fourth embodiment shown in FIG. 5, a part of the reinforced concrete 1 constituting the flooring device is opened up to the reinforcing bars 6, while the conductive member 2 has a downward protrusion when it is laid. After forming the portion 2a, the C1 conductive member 2 and the reinforcing bar 6 are electrically connected to the protruding portions 2a-c'. Therefore, the fourth
Both the small embodiment shown in the figure and the embodiment shown in FIG. 5 can form a conductive pavement with extremely excellent earthing function.

As described above, in the present invention, a conductive member is laid on the top surface of the floor pavement when flammable materials are handled at gas stations, etc., so that static electricity stored in automobiles and human bodies can be reliably dissipated into the ground. This eliminates the risk of gasoline igniting due to static electricity. Furthermore, since the conductive material is coated on the surface of the floor pavement such as concrete, it can also be used to repair cracks and the like on the floor pavement surface.

Furthermore, by using the resin Lrutal as the conductive member, water resistance and oil resistance can be improved. In addition, resin mortar has excellent workability and can be installed in a short time. Furthermore, if this construction is carried out only at the refueling position of a car at a gas station, the role of #i Makoto υ1 indicating the refueling area can also be fulfilled.
