DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a first plate member that is substantially vertically upright, and a second plate member that is arranged substantially horizontally and whose ends are fixed to the first plate member. And a plate structure having

[Conventional technology]

Plate structures of the above type, which are configured, for example, as the body of an automobile, the bed of a truck or a structure, are well known in the art.

FIG. 1 shows an example of a plate structure configured as a truck bed. The luggage carrier 1 shown here includes a floor panel 2 which constitutes a luggage loading surface, a header board 3 which is located in the front portion thereof, side panels 4 and 5 which are fixed to both sides of the floor panel 2, and a rear portion of the floor panel. And an opening / closing door 6 supported so as to be freely opened and closed.

The header board 3 is substantially upright in the vertical direction, the floor panel 2 is positioned substantially horizontally, and the front end of the floor panel 2 is fixed to the header board 3. In this way, the header board 3 constitutes the first plate member and the floor panel 2 constitutes the second plate member.

Conventionally, as shown in FIG. 7, the width direction W (first
To the cross sill 7 extending in the figure), the lower end portion of the header board 3 which is the first plate member is fixed by the bolt 8 and the nut, and the front end portion of the floor panel 2 which is the second plate member is welded to the upper surface of the cross sill 7. The header board 3 and the floor panel 2 were integrally fixed via the cross sill 7.

By the way, when manufacturing the loading platform 1 as shown in FIG. 1 in an automobile manufacturing plant, after assembling the respective elements as shown in FIG. 1, the loading platform is electroplated as shown in FIG. It is passed through the electrodeposition liquid in the tank 9, and the loading platform 1 is electrodeposited between them.

Immediately after being pulled up from the electrodeposition coating tank 9, since the electrodeposition liquid has entered the loading platform 2, it is necessary to allow the electrodeposition solution accumulated on the loading platform to flow down early.

[Problems to be solved by the device]

However, since the floor panel 2 and the header board 3 of the conventional loading platform 2 are fixed with no gap between them as shown in FIG. 7, the loading platform 2 is pulled up from the electrodeposition coating tank 9. At this time, the electrodeposition liquid accumulated on the floor panel 2 does not immediately flow out from the inside of the header board 3 and the floor panel 2, which causes a decrease in the production efficiency of the luggage carrier.

A method of forming an escape port for the electrodeposition liquid on the floor panel 2 or the header board 4 and allowing the electrodeposition liquid to flow down through the exhaust port at an early stage may be considered. However, if such an escape port is formed,
It is necessary to close the escape port with a plug in a later process,
The work is complicated and the cost increases.

An object of the present invention is to provide a plate structure in which the above-mentioned conventional drawbacks are eliminated by a simple structure.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a plate structure of the type described at the beginning, in which a flange portion substantially parallel to a general surface of the first plate member is provided at an end of the second plate member facing the first plate member. Is formed so as to hang downward, and a seating surface projecting from the general surface of the first plate member toward the second plate member is formed on the first plate member so as to be in close contact with the flange portion. By fixing the flange portions of the second plate member to each other, the general surface of the first plate member and the second plate member
A gap is formed between the end portions of the plate material, and when the gap is viewed from above, the shelf portion projecting from the general surface of the first plate material is arranged to cover the gap more than the lower end of the flange portion. The configuration formed on the lower first plate member portion is proposed.

〔Example〕

An embodiment of the present invention in which a plate structure is used as a bed will be described below with reference to the drawings.

The appearance of the luggage carrier in this example and the appearance of electrodepositing the luggage carrier at the time of manufacture are the same as in FIGS. 1 and 2. Therefore, in the following description, reference will be made to FIG. 1 and FIG. 2, and description of the same configuration as the conventional one will be omitted.

The point different from the conventional one is that the header board 3 forming the first plate member and the floor panel 2 forming the second plate member are connected as follows.

3 and 4, at the front end of the floor panel 2 facing the header board 3, a flange portion 10 that is substantially parallel to the general surface 3a of the header board 3 is formed so as to hang downward. On the other hand, a seating surface 11 protruding from the general surface 3a of the header board 3 to the floor panel 2 side is formed on the header hod 3 so as to be in close contact with the flange portion 10, and the seating surface 11 and the flange portion 10 are formed. , They are fixed to each other by spot welding as shown by the X mark in FIGS. 3 and 4. Instead of welding, the bolts and nuts may be fixed together. The cross sill 7 is fixed to the back surface of the floor panel 2 separated from the header board 3.

Since the floor panel 2 and the header board 3 are fixed as described above, a space between the general surface 3a of the header board 3 and the front end portion of the floor panel 2 is denoted by a symbol G in FIGS. 3 and 4.
A gap is formed as indicated by.

The carrier 1 assembled as shown in FIG. 1 is immersed in the electrodeposition liquid in the electrodeposition coating tank 9 shown in FIG. 2 and subjected to the electrodeposition coating treatment as in the conventional case. Tank 9
The general surface of the header board 3 when it is pulled up from
Since a gap G is formed between 3a and the front end of the floor panel 2, the electrodeposition liquid on the floor panel 2 quickly passes through the gap G as shown by the arrows in FIGS. 3 and 4. It flows down. In this way, the electrodeposition liquid accumulated on the carrier can be caused to flow down at an early stage, and the conventional drawbacks described above can be eliminated.

By the way, the cargo bed 1 is completed after undergoing the various steps as described above. At this time, if the gap G is left unattended, when viewed from above, the ground below the gap G It becomes fully exposed and its appearance deteriorates.
The gap G may be filled with a sealer or the like, but if this is done, the work of filling the sealer is required, and the cost of the bed increases.

Therefore, in the present invention, as shown in FIGS. 3 and 4, the header board portion below the lower end 10a of the flange portion 10 is provided with the shelf portion 12 projecting from the general surface 3a thereof. The shelf 12 projects from the general surface 3a toward the floor panel 2 and is positioned so as to cover the gap G when the gap G is viewed from above. Therefore, the completed loading platform 2
Even if there is a gap G in the ground, the ground is not exposed through the gap G, and the appearance of the ground can be prevented from deteriorating. Moreover, it is not necessary to fill the gap G with the sealer, and the increase in cost can be prevented.

In the embodiment shown in FIGS. 3 and 4, the lower end region 3b of the header board 3 is flush with the seating surface 11 so that the shelf
12 is configured so that the lower end region 3b can be used as a gripping margin when press-molding the header board 3 to manufacture the header board 3.

5 and 6 show an example in which the lower end portion of the header board 3 located below the lower end portion 10a of the flange portion of the floor panel 2 is bent toward the floor panel 2 side and the upper surface thereof is used as the shelf portion 12. ing.

The loading platform, which is an example of the plate structure, has been described above, but the present invention can be widely applied to other plate structures.

[Effect of device]

According to the present invention, the electrodeposition liquid can be quickly withdrawn from the gap between the first plate member and the second plate member during the electrodeposition coating of the plate structure, and the shelf is formed on the second plate member. Because
It is possible to prevent deterioration of the appearance of the completed plate structure without increasing the cost.
