Description

The present invention relates to a laminated structure .

In view of the above fact, an object of the present invention is to obtain a laminated structure capable of improving the bending rigidity with respect to the load in the wavelength direction of the corrugated plate portion.

The laminated structure of the present invention described in claim 1 comprises a first wall portion that forms undulations of a corrugated plate portion formed of a fiber reinforced resin material, and upper and lower end portions in the wave height direction of the corrugated plate portion. And a second wall portion connected to the first wall portion via a bent portion, and the second wall portion includes a general portion extending in the wavelength direction of the corrugated plate portion. , before Symbol alignment direction of general portion arranged reinforcing fibers are set in a direction along the wavelength direction of the wave plate portion, between the upper panel and the lower panel which face each other in the height direction of the wave plate portion The panel member is sandwiched, and the upper panel and the lower panel are respectively joined to the panel member and form a closed cross section with the panel member .

Moreover, the upper-lower end part of the wave height direction in a corrugated plate part is comprised by the 2nd wall part, and the 2nd wall part is connected to the 1st wall part via the bending part. Here, the second wall portion has a generally extending in the wavelength direction of the corrugated portion, the orientation direction of the reinforcing fibers disposed on one般部is set in a direction along the wavelength direction of the corrugated plate portion. Furthermore, in the laminated structure of the present invention, the panel member is sandwiched between the upper panel and the lower panel that are arranged to face each other in the wave height direction in the corrugated plate portion, and the upper panel and the lower panel are respectively joined to the panel member. At the same time, a closed cross section is formed by the panel member. For this reason, the laminated structure including the panel member is unlikely to bend and deform when a load in the wavelength direction of the corrugated plate portion is input.

The laminated structure according to a second aspect of the present invention is the structure according to the first aspect, wherein the general part does not contain at least bubbles larger in diameter than the reinforcing fibers.

According to a third aspect of the present invention, in the laminated structure according to the first or second aspect, the bent portion is formed in a curved shape and is set to a plate thickness equivalent to the first wall portion. At the end of the second wall portion on the side of the bent portion, a gradually changing portion whose thickness is gradually reduced as it is separated from the bent portion is formed.

According to a fourth aspect of the present invention, in the structure according to the first or second aspect, the bent portion is formed in a curved shape and is set to have a plate thickness equivalent to the second wall portion. At the end of the first wall portion on the side of the bent portion, a gradually changing portion is formed in which the plate thickness is gradually increased as the distance from the bent portion increases.

The laminated structure of the present invention according to claim 5 is the structure according to any one of claims 1 to 4, and extends from the bent portion to the side opposite to the first wall portion. The extending portion is formed integrally with the bent portion.

According to the above configuration, the extending portion extends from the bent portion to the side opposite to the first wall portion, and the extending portion is formed integrally with the bent portion. A force that causes the bent portion to bend inward and a force that causes the L-shaped portion extending from the second wall portion to the extending portion to act on the two wall portions cancel each other. Hold on. Thereby, the internal curvature of a bending part is suppressed.
The laminated structure according to a sixth aspect of the present invention is the structure according to any one of the first to fifth aspects, wherein the general portion has a higher density than the first wall portion.
According to the above configuration, since the bending strength and bending rigidity of the general part with respect to the load in the wavelength direction of the corrugated plate part are improved, the general part is not easily buckled against the load in the wavelength direction of the corrugated sheet part.

As described above, according to the laminated structure of the first aspect of the present invention, there is an excellent effect that the bending rigidity with respect to the load in the wavelength direction of the corrugated plate portion can be improved.

According to the laminated structure of the second aspect, there is an excellent effect that the bending rigidity with respect to the load in the wavelength direction of the corrugated plate portion can be further improved.

According to the laminated structure according to claim 3, in the case where the load is transmitted from one side of the wave height direction of the corrugated plate portion to the other side while suppressing the weakening of the second wall portion locally. It has the outstanding effect that a load can be transmitted favorably.

According to the laminated structure of claim 4, the bending rigidity of the bending portion with respect to the load in the wavelength direction of the corrugated plate portion is controlled by the orientation of the reinforcing fiber while suppressing the local weakening of the first wall portion. It has an excellent effect that improvement can be achieved.

According to the laminated structure of Claim 5, it has the outstanding effect that the internal curvature of the bending part which connects a 1st wall part and a 2nd wall part can be suppressed.
According to the laminated structure of the sixth aspect, it has an excellent effect that it is difficult to buckle the general portion against the load in the wavelength direction of the corrugated plate portion.
