た。 However, in such a conventional structure, if the roof panel is insufficient in tension and rigidity, countermeasures include increasing the thickness of the steel plate or adding a roof bow, which results in increased weight and parts, and also increases the risk of rain. In order to suppress indoor noise such as sound and vibration noise, it may be necessary to attach soundproofing and vibrationproofing materials such as felt and butyl rubber to the back of the roof panel. The problem was that it impeded improvement in performance and also impeded cost reduction.

It is disposed in a band shape in the width direction at a portion of the roof panel 1 with low surface rigidity, between the front end of the roof panel 1 and the front end of the roof panel 1, and between the roof bow 3 and the rear end of the roof panel 1. The material of the soft foam 6 is, for example,
Polyether-based soft urethane foam with a specific gravity of 0.22 is used, and the adhesive and curable resin liquid to be impregnated with is, for example, a two-component mixture type room temperature curing epoxy adhesive with a viscosity of 1000 to 1000 at 20°C.
A one-liquid adhesive and hardening urethane adhesive may be used, although a 2000 cp adhesive may be used.
補強構造の形成手順につき第４図および第５図
を参照して説明する。 The procedure for forming the reinforcing structure will be explained with reference to FIGS. 4 and 5.

Next, as shown in FIG. 5, the positional relationship between the roof panel 1 and the molded ceiling 4 is determined by using a jig or by actually assembling the molded ceiling 4 onto the vehicle body. Soft foam 6 is roof panel 1
and the molded ceiling 4, and is compressed according to the gap therebetween. For this reason, roof panel 1
An adhesive and curable resin liquid oozes out between the molded ceiling 4 and the soft foam 6 and between the molded ceiling 4 and the soft foam 6, hardens, and connects to the roof panel 1 through the soft foam 6. While bonding and joining the soft foam 6, the soft foam 6 also becomes hard.

る。 The roof panel 1 and the molded ceiling 4 are made of soft foam 6
As a result of being joined through the roof panel 1, the roof panel 1 is reinforced by the molded ceiling 4, and even if the roof panel 1 is thin, it can have the same rigidity as a thicker roof panel. Through mutually complementary actions, synergistic effects can be achieved.

100mm in width and 300mm in front and back, respectively.
In the case where the 1040 mm soft foam 6 is arranged in a strip shape in the width direction, point A was the weakest point in surface rigidity for the roof panel 1 with a thickness of 0.9 mm, so the test results for this point were Looking at the line diagram in Figure 6, in which the load applied in the planar direction is plotted on the vertical axis and the resulting displacement in the planar direction is plotted on the horizontal axis, it can be seen that in the case where the roof panel 1 and the molded ceiling 4 are not joined, the plate thickness is 0.9mm
It was line a 1 , which indicates the On the other hand, in the case where the roof panel 1 and the molded ceiling 4 are joined to each other with a thickness of 0.9 mm, the results shown in line a2 are obtained, and the difference in surface rigidity is obvious, and the surface rigidity is significantly improved. It is clear that The actual measured value of line a 2 has almost the same tensile rigidity as a roof panel with a thickness of 1.0 mm, and the weight of roof panel 1 is an actual measured value, and the thickness
The 1.0mm plate weighs 15.55Kg, while the 0.9mm plate weighs 14.16Kg, which is significantly lighter.

合することができる。 As explained above, according to the automobile roof reinforcing structure according to the present invention, since the roof panel and the molded ceiling are joined, the rigidity of the roof panel can be significantly increased, and as a result, the roof panel Since the thickness of the steel plate can be reduced, the weight of the vehicle body can be reduced, contributing to resource and energy conservation. In addition to suppressing vibrations in the roof panel and reducing noise inside the vehicle, conversely, the molded ceiling is supported by the reinforcing structure, making it possible to prevent it from sagging over time. Since the gap between the roof panel and the molded ceiling is filled using the deformation of the soft foam, even complex gaps can be perfectly followed and joined.
