Therefore, the main object of the present invention is a camping trailer superstructure consisting of a panel constituting the upper structure of the camping trailer wall, ceiling, floor surface and the connecting structure to maintain the box-shaped shape of the panel, the lightweight high rigidity characteristics The composition method of composite composite panel having insulation and soundproofing effect, the box-shaped structure formed by the panel and the method of steel connection in right angle, respectively, and the corner part connecting panel and the panel have three-dimensional connection structure. And to provide a light weight camping trailer superstructure is blocked air.

The present invention for achieving the above object relates to light weight and high rigidity in the manufacture of a light weight camping trailer, in each side of the upper box structure, the outer side of the glass fiber reinforced plastic sheet without the joint The aluminum thin plate is formed on one surface of the glass fiber reinforced plastic sheet and is bonded in one direction by minimizing the joint, and the aluminum honeycomb cell connector is continuously bonded in a direction perpendicular to the arrangement of the aluminum sheet and the arrangement of the aluminum honeycomb cell connector A composite panel part in which aluminum thin plates are bonded to each other by minimizing a joint in a right angle direction, and an aluminum tube frame assembled at predetermined intervals by a predetermined coupling method inside the composite panel part, and a heat insulating material having the same thickness as the frame is disposed between the frames. And bonded to the frame and insulation surface Provides a top structure for light weight camping trailer, characterized by the combination of the wall and the floor, the ceiling panel is constituted by an internal insulating interior consisting of a built-in plywood panels are joined by the formula:

In addition, in rigidly coupling the wall, floor, and ceiling structures according to the present invention, the outer aluminum sheet of the composite panel part is geometrically closed, and the upper and lower honeycomb core cell connectors and the aluminum sheet are pre-positioned and adhered to the wall surface. It is characterized by post-positioning the honeycomb core cell connector and the aluminum sheet.

In addition, in the assembly of the side composite panel according to the present invention is characterized in that the C-shaped aluminum channel equal to the thickness of the honeycomb core on the upper portion in advance to increase the bonding rigidity of the ceiling portion and the wall portion.

In addition, in the heat insulation interior portion according to the present invention is characterized in that the aluminum frame is connected to the composite panel portion in a closed form of a spherical shape is connected by a predetermined connection method.

Hereinafter, the construction method of the lightweight camping trailer according to the present invention will be described in detail with reference to the accompanying drawings.

Components of the glass fiber reinforced plastic (401), the outer aluminum sheet (402-1). An aluminum honeycomb cell connector 403, an inner aluminum thin plate 402-2, an aluminum frame 414, a heat insulating material 415, and a built-in plywood 416.

2 to 4, the lightweight camping trailer upper structure of the present invention is the outermost outer shell 11, 401 of the glass fiber reinforced plastic sheet is formed on the outer side is formed a predetermined width on one surface of the outer shell Aluminum thin plates 12-1 and 402-1 are bonded in a single direction so that the joints are minimized. Bonding the aluminum honeycomb cell connectors 13 and 403 to the aluminum thin plates 12-1 and 402-1 in a direction perpendicular to the arrangement of the aluminum thin plates 12-1 and 402-1. Let's do it. Aluminum thin plates 12-2 and 402-2 are bonded to the inside of the aluminum honeycomb cell connectors 13 and 403 at right angles to the arrangement of the 13 and 403. The series of composite materials, namely glass fiber reinforced plastics 11, 401, aluminum thin plates 12-1 and 402-1, aluminum honeycomb cell thermal binders 13 and 403, aluminum thin plates 12- 2) and (402-2) are bonded by an orthogonal arrangement and a resin-based adhesive to form the composite composite panel portion 40. The composite panel part 40 has both the wall, the bottom, and the ceiling have the same box-shaped cross-section as shown in FIG. 2, and the aluminum formulation frame 14 having the outside standard having the same standard as the inside of the composite panel part 40 is fixed. Float at intervals and join in a certain way Filled between the aluminum formulation frame 14, which is bonded at regular intervals with a heat insulating material 15, the plywood interior material 16, 416 is bonded to the formulation frame 14, 414 and the heat insulating material 415.

In addition, as shown in FIG. 2, the outer aluminum thin plates 12-1 and 402-1 are closed or the joints are prevented from forming at the corners to increase watertightness, and the bottom and ceiling of the aluminum Hannicom cell connector first. (13), (403) and the inner aluminum thin plates (12-2), (402-2) are bonded to the C-shaped aluminum channel (on both sides of the inner aluminum thin plates (12-2), (402-2) ( 17) is placed first.

Advantages of the present invention are as follows. In the case of the aluminum honeycomb cell connector, which is a component of the composite panel 40, the aluminum has a weight of 3% and a volume of 97% of air, so that the weight of the aluminum honeycomb cell connector may be reduced while maintaining rigidity. In addition, in the case of the floor, ceiling, and wall components, glass fiber reinforced plastic thin plates 11 and 401 achieve an improvement in waterproof performance by forming an integral part without connection on one surface. In addition, since the arrangement of the components constituting the composite composite panel 10, that is, the components at the time of bonding the (11), (12), (13) is orthogonal arrangement of the composite composite panel can be achieved. In addition, it is possible to maintain the box shape of the superstructure by further placing the aluminum frame composed of the formulation.
