[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used in combination with a reinforcing member on the chassis frame side or the vertical joist side when fastening with U bolts, more specifically with U bolts used when mounting a platform on the chassis frame of a truck. It relates to the chassis frame or vertical joist reinforcement (hereinafter also referred to as "reinforcement when U bolts are fastened" or simply "reinforcement").

[0002]

[Prior art]

 Conventionally, freight trucks have been equipped with a loading platform on the chassis frame of the truck. At that time, as shown in FIG. 1, a vertical joist 12 is attached to the chassis frame 10 by a U-shaped bolt (not shown). The trucks 16 are connected to each other and the loading platform 14 is installed on the trucks 16.

However, since the chassis frame 10 is usually a U-shaped cross-section material, when the whole is fastened with U-shaped bolts to attach vertical joists or the like, the shape may be crushed. .

Therefore, in the prior art, for example, a reinforcing member 18 as shown in a schematic perspective view in FIG. 2A is used. That is, it is a solid spacer 20 made of wood, iron, or resin that is inserted in a space of U-shaped cross section of the chassis frame, and has a rectangular parallelepiped shape as a whole, and one side surface 22 accommodates a U bolt. The groove 26 is provided.

As shown in FIG. 2B, a U-shaped bolt 24 fastens the chassis frame 10 having a U-shaped cross section and the vertical joist 12 with the solid spacers 20 interposed therebetween. . In the example shown in FIG. 2B, the vertical joist 12 is shown as a solid body, but in some cases, the vertical joist 12 may also be formed in a U-shaped cross section to further reduce the weight. However, in the following, the present invention will be described by taking the case where only the chassis frame 10 has a U-shaped cross section as an example.

By the way, the dimension of the U-shaped space portion of the chassis frame 10 differs depending on its position. In other words, the chassis frame 10 is provided with one kind of taper on the upper side, and taper toward the rear end. See FIG. Therefore, the size of the U-shaped space in the height direction is, for example, a large vehicle (10-ton vehicle) with a maximum length difference of 400 mm and a minimum length of 200 mm. Since they are fastened, it is necessary to have 5 to 6 solid spacers suitable for each size. Since different models will have different dimensions, the above-mentioned solid spacers must be prepared in large numbers according to their respective sizes, and spacers of various sizes are always available. There was a case where it was necessary to keep the stock as inventory.

Thus, the object of the present invention is to eliminate the need to stock such a large number of spacers in stock, and at the time of U-bolt fastening, which is inexpensive and can be assembled to the appropriate size on site. It is to provide a reinforcing material to be used.

[Means for Solving the Problems]

 The present invention is a chassis frame or a vertical joist reinforcement member used in combination with a U-bolt when mounting a loading platform on a chassis frame of a truck, and includes a flat plate-shaped main body and a main body of the main body. The upper surface and the lower surface are provided with a portion that engages with the spacer, and a contact surface that is provided on the surface of the main body opposite to the surface that engages with the spacer and that faces the reinforced surface. , Is a reinforcing member when fastening the U bolt.

According to a preferred embodiment of the present invention, a U-shaped groove for receiving a U-bolt may be provided at one end of the main body. According to still another aspect, a stepped portion that engages with an end surface of the surface to be reinforced may be further provided on the side of the main body where the U-shaped groove is provided. The portion of the reinforcing member of the present invention that engages with the spacer is capable of receiving the spacer, which is, for example, a rod-shaped body or a tubular body (eg, pipe).

[0010]

[Action]

 As described above, according to the present invention, the solid spacer, which has been integrally formed so far, is engaged with the rectangular or round or other flat plate-shaped main body at both ends. It is possible to easily deal with the fluctuation of the separation distance of the inner space of the frame by constructing the separation material and by separating the separation material from each other to obtain the proper separation material.

In particular, the whole portion is not required to be in the shape of a solid rectangular parallelepiped, and the intermediate portion may be preferably provided with a spacer, which is a pipe, and the weight is significant for a truck, which is significant.

【Example】

 Next, embodiments of the present invention will be described with reference to the accompanying drawings. 3 (a), (b) and (c) are a plan view, a side view and a front view of the reinforcing member 18 according to the present invention, and FIG. 4 is a schematic perspective view showing its assembly. .

As can be seen from FIGS. 3 and 4, the reinforcing member 18 according to the present invention is composed of a rectangular plate-shaped main body 30 in the illustrated example, and one of upper and lower surfaces 32 thereof has a pipe, A portion of the rod or the like that is cut to an appropriate length and engages with the spacing member 40.In the illustrated example, the projection 34 that enters the pipe and the opposite flat surface 36 are the inner surface of the U-shaped frame. That is, the contact surface 38 that is abutted against the reinforced surface (not shown) is provided. The protrusion 34 forming the above-mentioned portion may have a tubular shape and receive the spacer 40 therein. Alternatively, a simple recess may be formed to receive the end of the spacer 40.

Since such a reinforcing member 18 is usually used by fastening with a U bolt (not shown), a groove 42 for receiving a straight portion of the U bolt is provided at one end of the main body. In the present invention, the side where the groove 42 is provided may be provided with a stepped portion (not shown) that engages with the end surface of the frame and is effective in fixing the position when the U bolt is fastened. The stepped portions 44a, 44b, 44c are provided around the portion and the groove. Of course, the entire region where the groove 42 is provided may be the stepped portion.

FIG. 5 is a partial perspective view when the vertical joist 12 is assembled to the chassis frame 10 using the U bolt 24. At this time, the separating member 40 can be adjusted in length at the time of assembly by cutting a familiar material such as a pipe and a rod into appropriate lengths. Moreover, the separating material such as the pipe interposed between the reinforcing materials according to the present invention can be easily obtained on site.

[0016]

[Effect of device]

 According to the present invention, even if the size of the inner space of the U-shaped chassis frame changes, the length can be adjusted on site by cutting and assembling the spacer to a predetermined length each time. Therefore, it is sufficient to hold only one type of reinforcing material as an inventory.

In the truck body assembly plant, various pipes, rods, etc. are used in various ways. In the present invention, the end material can be appropriately cut and used, and in terms of effective use of resources, The significance of the invention is great.
