Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a light metal plate panel fixing structure for a van-type vehicle loading platform.

[Prior Art] Fig. 4 to Fig. 6 show conventional examples, in which Fig. 4 is a side view of a light metal panel fixing structure of a conventional van-type vehicle loading platform, and Fig. 5 is B of Fig. 4. −
6 is a cross-sectional view of a plate panel structure showing another conventional example, and 13 is a sectional view taken along the arrow B line. This is reinforcement for iron-based materials. First, in the conventional example shown in FIG.
The roof panel 2 is placed on the top surface, and a large number of rivets 14, 14 are placed at predetermined intervals.
But it was tacked on. The rivet heads 14' of this roof panel 2 were also coated with a sealer or the like. Further, in another embodiment shown in FIG. 6, a double-sided adhesive tape 4' is pasted on the upper surface of the reinforcement 13, and is adhered to the inner surface of the roof panel 2, and at predetermined intervals. , were fixed with a large number of mounting screws 14'', 14''.

However, with the conventional van-type vehicle loading platform 11 having a fixed structure of light metal plate-clad panels, when the outside temperature rises, such as under the blazing sun in summer, the light metal plate-clad roof panel 2
Due to the difference in the expansion rate of the reinforcing material 13 made of iron-based material, the parts of the light metal sheet roof panel 2 of the van-type vehicle loading platform 11 other than the riveted parts are lifted up, resulting in wavy and uneven surfaces. There was a problem with surface quality in light metal sheeting technology, where only surface quality could be ensured.

To summarize, in the case of the conventional light metal plate panel fixing structure of the van-type vehicle loading platform, (1) the free parts of the light metal plate roof panel other than the riveted areas are raised, resulting in uneven surface quality; The problem is that it can only be secured.

(2) The above-mentioned problem of rain leaking into the van-shaped loading platform due to peeling of the coating sealer at the rivet area.

(3) The structure for fixing the panels had to be expensive.

This is because there were various troublesome tasks such as drilling pilot holes for rivets, driving rivets, and applying sealant to the rivet heads.

[Problem to be solved by the invention] In the light metal plate panel fixing structure of the van-type vehicle loading platform of this invention, parts of the light metal plate-clad roof panel of the van-type vehicle loading platform other than the riveted parts are raised. This was devised in view of the problem of only being able to ensure the uneven surface quality of the outer surface, and was developed with the aim of improving the quality of the light metal plated panels of van-type vehicle loading beds. The present invention provides a panel fixing structure for a van-type vehicle loading platform that prevents light metal plate panels from lifting up when the outside temperature rises.

[Means for solving the problem] The gist of the light metal plate panel fixing structure for a van-type vehicle loading platform of this invention is that in the panel fixing structure for a van-type vehicle loading platform equipped with a light metal plate-clad roof panel, a rectangular tube-shaped An opening periphery is provided on the side surface of the reinforcement, and a strip on the narrow width side of a light metal extruded material having an inverted U-shaped cross section is fitted and secured to the opening periphery, and the wide side of the extruded material is The feature is that the entire surface of the strip is glued to the roof panel.

[Example] An example of this invention will be described in detail with reference to the drawings. Figures 1 to 3 show the light metal panel fixing structure of the van-type vehicle loading platform of this invention. 1 is a sectional view taken along the line A-A in FIG. 1, and FIG. 3 is a sectional view of the extruded material.

In the figure, 10 is a van-type vehicle loading platform equipped with the light metal sheet roof panel fixing structure 1 of this invention;
2 is a light metal plate panel fixing structure of this van-type vehicle loading platform, and 2 is a light metal plate-clad roof panel of this van-type vehicle loading platform 10.

Reference numeral 3 denotes a rectangular tube-shaped reinforcement incorporated inside the roof panel 2. In this reinforcement 3, the roof panel 2
An opening periphery 31 is opened over the entire length by a predetermined width toward the inner side of the opening. Reference numeral 4 denotes an adhesive or a double-sided adhesive tape for bonding the inner surface of the board-clad roof panel 2 to an extruded material 5, which will be described later.

Reference numeral 5 denotes a light metal extrusion material such as aluminum for the plate-clad roof panel fixing structure 1 of this van-type vehicle loading platform 10.

Therefore, in the panel fixing structure 1 for a van-type vehicle loading platform equipped with a roof panel 2 covered with a light metal plate such as aluminum, an opening periphery 31 is provided on the upper side surface of the reinforcement 3 which has a rectangular tube shape as a whole. As shown in FIG. 3, the strip 52 on the narrow side of the mold material 5 whose overall cross section is in the shape of an inverted square is fitted and engaged, and the entire surface of the strip 51 on the wide side of the mold material 5 is fitted. Then, an adhesive 4 is applied to bond the profile 5 and the roof panel 2 together.

[Function] With such a light metal plated panel fixing structure, the roof panel and the profile are made of the same material, so their expansion rate is the same in response to temperature changes, and the above-mentioned adhesive does not peel off. Moreover, since the reinforcement and the profile material slide, the above-mentioned waving of the roof panel can be prevented.

[Effects of the invention] The light metal plated panel fixing structure of this invention has been explained in detail above. This light metal plated panel fixing structure has the following advantages: (1) By using the same material for the light metal plated roof panel and the profile material, Since the mold material is slidably attached to the upper surface of the reinforcement without the adhesive coming off, the roof panel does not lift up and a smooth surface quality can be ensured.

(2) There are no rivet holes as in conventional fixed structures, there is no peeling of the sealer covering the rivet area, and no rain leaks into the loading platform.

(3) There are few factors that increase the cost of the panel fixing structure.

This is because unlike conventional methods, there is no need to drill pilot holes for rivets, and there are no troublesome operations such as driving rivets, applying sealer to the rivet heads, etc., and it is only a simple operation.
