Description

[Detailed Description of the Invention] (Related Industrial Field) The present invention relates to a roof structure for a van type vehicle, a sea container, etc. (hereinafter referred to as a transport container).

(Prior Art) The roof structure of a conventional transportation container will be described with reference to FIGS. 4 to 7. FIG. 4 is a perspective view of the transport container A, FIG. 5 is a view taken along the - arrow in FIG. 4, and FIG. 6 is a sectional view of the roof beam.

The roof of the transport container A has a roof beam 4 placed on an inward horizontal flange 3 of an upper side frame member 2 of a side wall 1 and fixed at both ends with fixing means 5 such as rivets or fasteners. The roof beams 4 are arranged at approximately equal intervals in the longitudinal direction of the transport container A, and the roof beams 4 are arranged at approximately equal intervals in the longitudinal direction of the transport container A.
covered with.

The roof beam 4 has a hat-shaped cross section, as shown by reference numeral 4' in FIG. 6A, or a Z-shaped cross section, although not shown. These can be fixed with solid rivets 8 by inserting a riveting machine as shown in FIG. However, the flange 7 extending outward at the lower end may damage the cargo, or the flange 7 may be pushed upward by the cargo, causing accidents such as damage to the roof board.

In order to eliminate such accidents, Utility Model No. 54-134123
A roof beam as shown in the publication (Figure 6b) was proposed. However, this requires 1) placing both ends of the roof beam 4'' on the horizontal flange 3 of the upper side frame member 2 and fixing them with solid rivets 8 before covering the roof board 6; 2) the roof beam 4; After covering both ends of the roof plate 6 with the horizontal flange 3
In the case of fixation, solid rivet cannot be used, and only fasteners with weak fixing force such as pot rivet 9 which are riveted from one side can be used.

(Problems to be solved by the invention) Incorporating the advantages of roof beams with a cross-sectional shape as shown in Figure 6 (b) (shape that does not damage cargo or the roof),
It is an object of the present invention to provide a roof beam that does not impair its strength as a roof beam and can firmly fix the inward horizontal flange of an upper side frame member and the end of the roof beam with a solid rivet after covering with a roof plate. .

(Means for solving the problem) A roof beam installed between the upper side frame members has a base with an I-shaped cross section, a lower flange of the base extending longer than the upper flange on both sides, and then an oblique side raised diagonally upward. , and an end side that is parallel to the upper flange and folded back so that its top surface is a very small dimension lower than the top surface of the upper flange at the end of the oblique side, and the roof beam is configured to be symmetrical on both sides. After cutting off a little of the oblique side and end side for riveting work and attaching these to the back of the roof board at regular intervals, place the end of the roof beam on the inward horizontal flange of the upper side frame material, and It is characterized in that a riveting machine is inserted from the upper part and the riveting machine is fixed to the upper side frame material with a solid rivet.

(Example) Reference numeral 10 in FIG. 1 indicates a roof beam of the present invention, and FIG. 2 is a sectional view thereof. The roof beam 10 includes a base 11 having an I-shaped cross section and a lower flange 1 of the base 11.
2 and 13 on both sides longer than the upper flanges 14 and 15, and then the oblique side 1 is made to stand diagonally upward.
6, 17, and the ends of the hypotenuses 16, 17 are parallel to the upper flanges 14, 15, and the top surfaces thereof are extremely smaller in dimension δ than the top surfaces of the upper flanges 14, 15.
End sides 18 and 19 are folded horizontally so as to be lower, and the overall structure is symmetrical.

As shown in FIG. 1, oblique sides 16, 17 and end sides 18, 19 are cut out by a length l that allows insertion of a riveting machine, which will be described later, at both ends. As shown in FIG. 3, this notch is provided so that the receiving portion 20 of the yoke of the riveting machine R can be inserted into the space of the I-shaped base. By doing so, the solid rivet 21 can be driven, and the strength of the roof beam 10 can also be maintained.

(How to attach the roof) 1. Cut both ends of the roof beam 10 by a length l and glue it to the back surface of the roof board 6 at regular intervals. In this case, the adhesive is applied on the upper flanges 14, 15 of the I-shaped base 11, as shown by the reference numeral 22 in FIG. I'll let it happen.

2 Rivet 23 the end of the roof plate 6 with the roof beam 10 to the upper horizontal flange 22 of the upper side frame material 2.
(Figure 3).

3. Insert the receiving parts 20 of the yoke of the riveting machine R into the notches 24 at both ends of the roof beam 10, and caulk and secure the solid rivets 21.

(Effects) Adhesive is used to fix the roof plate 6 and roof beam 10 of the large transport container. This bonding process requires special large-scale equipment. Therefore, the end of the roof beam 10 and the inward horizontal flange 3 of the upper side frame member 2 must be fixed after the roof plate 6 is covered on the upper side frame member 2, and in particular, the fixation as shown in FIG. In the structure shown, only blind rivets can be used as mentioned above, and there is a drawback that strong fixation cannot be achieved.

On the other hand, the roof beam is formed with hypotenuses on both sides of the lower flanges 12 and 13 at the base of the I-shaped cross section, followed by horizontal edges, and both ends of the roof beam are notched and bonded to the roof board in advance. Then, it became possible to securely fix the ends of the roof beams to the inward horizontal flanges of the upper side frame members from the inside using solid rivets. This configuration prevents luggage from getting caught, and also prevents damage to the roof panels.
Furthermore, a sturdy roof structure can be obtained by using strong roof beams.
