Description

  The present invention relates to a fender for a fire-fighting pump car and other specially equipped vehicles, and a method for manufacturing the same.

For example, it is necessary to make it more difficult to slide because there are many operations such as climbing a fender on a roof instead of a stepping platform, taking out a ladder and a hose, and storing them.
Therefore, in this type of vehicle, as shown in FIGS. 8 and 9, an aluminum striped plate 2 having a small protrusion 2a for preventing slippage on the surface is joined onto an iron plate fender 4 to attach the vehicle fender. Production is done.

  Here, when the iron plate fender 4 is attached by the aluminum striped plate 2, a fixing member 6 such as a bolt or a rivet is driven between the iron plate fender 4 and the striped plate 2, and the driven portion is covered. Filled with caulking material, etc. to prevent leakage of fender water.

  By the way, in particular, fire pumps and special vehicles for disaster relief often travel on bad roads such as puddles. For this reason, muddy water and the like frequently jump from the tire to the lower surface side of the iron plate fender 4 during traveling.

  In such a case, if the caulking material has deteriorated or if a caulking material filling error or the like has occurred, the moisture in the muddy water escapes upward through the hole into which the fixing member 6 is driven, As a result, there was a problem that the surface of the aluminum stripe plate 2 was wetted.

In such a case, when it puts on the aluminum strip board 2, it will become slippery.
In addition, the centrifugal force of the tire 10 causes rain water or the like to hit the bolt holes or rivet holes, and the iron fender 4 may rust and deteriorate within a few years, and periodic re-cooking of the caulking agent is necessary. It was.

  The present invention has been made in view of such circumstances, and even when traveling on a bad road such as a puddle, moisture due to rebound from the tire is prevented from leaking to the front side, and An object of the present invention is to provide a fender for a fire-fighting pump car and other specially equipped vehicles that does not cause deterioration due to the generation of rust, and a method for manufacturing the same.

  Furthermore, the present invention provides a fender for a fire-fighting pump car and other specially-equipped vehicles that can perform a non-slip treatment even when wet and can eliminate troublesome work such as filling of a caulking agent at the time of production and periodic. And it aims at providing the manufacturing method.

In order to achieve the above object, the fender of a fire-fighting pump vehicle and other specially equipped vehicles according to the present invention,
The fender main body formed by curving the surface facing the tire in a circular arc shape is integrally formed by a striped plate made of FRP.

  According to such a fender of a fire fighting pump vehicle or other specially equipped vehicle according to the present invention, as in the case of laminating a steel plate fender and an aluminum striped plate, a fixing member such as a bolt or a rivet is driven into the part. The trouble of filling the caulking agent can be saved.

Therefore, since a hole through which water is removed is not formed, it is possible to prevent moisture from escaping upward from the fender due to rebound from the road surface side.
Moreover, it is preferable to shape | mold the thickness of the fender of the vehicle which concerns on this invention in the range of 4-5 mm including the said strip made from FRP.

If it has such a thickness, sufficient strength can be maintained.
Furthermore, the fender manufacturing method according to the present invention includes:
A wooden mold manufacturing process for manufacturing a wooden mold in which the shape of the fender is shaped on the surface,
An aluminum stripe plate mounting step of attaching an aluminum stripe plate on the wooden mold obtained in the wooden mold production process;
A resin mold forming process for producing a resin mold by applying resin to the completed wooden mold obtained by the aluminum stripe plate mounting process while overlapping a plurality of layers of glass fibers;
A resin mold demolding step of demolding the resin mold obtained by the resin mold molding process from the surface of the finished wooden mold;
A product molding step in which a resin is applied to the molding surface of the resin mold that has been removed by the resin mold demolding step and the resin is applied at room temperature while overlapping glass fibers;
A product demolding step of demolding the product obtained in the product molding step from the resin mold.

  According to the fender manufacturing method comprising such steps, it is possible to manufacture a fender exhibiting the same slip resistance and strength as when using an aluminum stripe plate without using an aluminum stripe plate.

In addition, since the fender is composed entirely of resin strips, it is possible to exert strength while promoting weight reduction. Further, even when higher strength is required, the thickness can be arbitrarily increased and the strength can be increased by increasing the number of glass fibers in the same mold.
Since it is not necessary to fix to the iron plate fender with bolts or rivets, the number of labor can be reduced.

  According to the fender of the fire fighting pump vehicle and other specially equipped vehicles according to the present invention, instead of laminating the aluminum stripe plate on the iron plate fender, all the fenders are formed with the FRP stripe plate, and only the FRP stripe plate is used for the fender. Therefore, the weight of the fender can be greatly reduced.

Moreover, according to the fender of the fire fighting pump vehicle and other specially equipped vehicles according to the present invention, since there are no bolt holes or rivet holes, rainwater bounced off the tire does not enter the holes.
As described above, the present invention is not made of metal that needs to be perforated, and is entirely made of a resin material, so that deterioration due to rust does not occur. Furthermore, if anti-slip special coating is applied to the FRP stripe plate, an anti-slip effect superior to that of the aluminum stripe plate can be obtained.

  Further, according to the fender manufacturing method of the present invention, it is not necessary to drive in a fixing member such as a bolt or a rivet or to load a caking agent, so that the number of labor can be reduced.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a method of manufacturing a fender according to an embodiment of the present invention in the order of steps.

  As shown in FIG. 1, the fender manufacturing method of the present embodiment includes a wooden mold manufacturing process 1, an aluminum stripe plate mounting process 3, a resin mold molding process 4, a resin mold demolding process 8, and product molding. It has the process 10 and the product demolding process 12. The outline of each process is shown in FIGS.

As shown in FIG. 2, first, a wooden mold 14 is prepared in which the shape of a vehicle fender is formed on the surface.
This wooden pattern 14 corresponds to the shape of the rear fender of the vehicle, for example, and has a height T of about 60 cm and a width S of about 20 cm.

  Further, in the method of manufacturing the vehicle fender of the present embodiment, although it is finally unnecessary, until the middle step, as in the case of the conventional example shown in FIGS. An aluminum stripe plate 2 having a small projection 2a is used.

Thus, the aluminum strip 2 used halfway is attached on the wooden mold 14 prepared in advance as shown in FIG.
As described above, the aluminum stripe plate 2 uses the pattern of the protrusions 2a at an early stage for transfer, but is not used finally.

As shown in FIG. 2 or FIG. 3, a fixing member 18 such as a tapping screw inserted in advance in the aluminum striped plate 2 is hit against the wooden mold 14 to form a completed wooden mold 20.
Thus, when the aluminum strip 2 is attached to the surface of the wooden mold 14 to form the completed wooden mold 20, the upper surface of the completed wooden mold 20 comprising the wooden mold 14 and the aluminum strip 2 as shown in FIG. Six to seven layers of glass fibers are laminated.

  Here, it is necessary to apply a glass fiber having a sufficient thickness of about 5 to 6 mm to the upper layer of the finished wooden mold 20, and the glass fiber resin applied with a sufficiently thick thickness is later cured, whereby the upper surface of the wooden mold 14 is The resin mold 22 is obtained on the side.

At this time, fine irregularities are formed on the lower surface of the resin mold 22, that is, on the inner surface 22 a in contact with the aluminum stripe plate 2, with the shape of the protrusion 2 a of the aluminum stripe plate 2 being inverted.
When such a resin mold 22 is cured, the resin mold 22 is removed from the wooden mold 14 as shown in FIG.

When the resin mold 22 is removed from the finished wooden mold 20, the inner surface 22 a of the resin mold 22 is provided with fine irregularities formed by reversing the protrusions 2 a of the aluminum stripe plate 2.
When the resin mold 22 having the fine irregularities on the inner side surface 22a is removed from the completed wooden mold 20, the completed wooden mold 20 composed of the wooden mold 14 and the aluminum stripe plate 2 has the required number of resin molds. Is not required. That is, it is removed from the subsequent steps.

  On the other hand, the resin mold 22 obtained in the process of FIG. 5 proceeds to the product molding process 10 of FIG. 6 which is the next process. In this step, a glass fiber-containing resin 26 containing glass fibers is applied to the inner side surface 22a of the resin mold 22 via a release agent (not shown). When the glass fiber-containing resin 26 is cured, specifically, it may be about 4 to 5 mm, but it becomes stronger as the number of layers is increased.

Such a layered product of the glass fiber-containing resin 26 can be formed, for example, by repeatedly applying a roller several times.
Then, as shown in FIG. 7, if the room-temperature-cured product 26 is removed from the inner surface 22a of the resin mold 22, a product that is a substitute for the aluminum strip 2 used first, that is, a strip made of FRP. 26 can be obtained.

  In this way, a large FRP strip 26 corresponding to the fender shape of the vehicle can be formed. Further, the FRP strip 26 has projections on the surface 26a similar to those of the aluminum strip 2.

As shown in FIG. 7, the resin mold 22 after the product 26 (FRP stripe plate 26) is removed is repeatedly used as a mold for obtaining a large number of products 26 thereafter.
In the present embodiment, a resin fender corresponding to a vehicle fender can be obtained by using only the FRP stripe plate 26 by performing the above steps in order.
The resin fender (product 26) is attached to the vehicle.

  As described above, the vehicle fender manufactured according to the embodiment of the present invention has been described. However, the fender according to the present invention does not stack the product 26 on the iron fender, but the product 26 itself is incorporated into the vehicle as a fender. It is what Therefore, it is not necessary to make a hole in the portion facing the tire in order to pass the bolt or rivet. Therefore, it is not necessary to perform special water leakage treatment. Furthermore, the strength as a fender is sufficient.

Moreover, since all this resin fenders are resin, they are lightweight. Therefore, the weight of the vehicle can be greatly reduced.
In addition, even if people walked on it, it would not dent and could be applied to fire-fighting pump cars and specially equipped cars.

  As mentioned above, although one Example of this invention was demonstrated taking the case of manufacturing the rear fender of a vehicle as an example, this invention is not limited to this, Of course, it can apply also to the fender of a front side.
