The heat insulating material 52 is adhered and attached to each panel at each installation position, and is pressed in each panel direction by the ceiling interior plate 51, the luggage rack 55 and the side interior plate 56. Therefore, the ceiling interior plate 51, the luggage rack 55, and the side interior plate 56 are made of the heat insulating material 52.
The generation of the vibration of each member itself is suppressed by receiving the half force from.

The mold material at the joint between the floor panels 16 includes
A floor support girder 61 that supports the floor panel 17 is supported and fixed by fastening bolts 44. The floor panel 1
Reference numeral 7 denotes an adhesive honeycomb panel configured by installing an aluminum alloy plate material and an aluminum alloy honeycomb material, and forms a space for installing the conditioned air duct 58 and the return duct 59 with the floor panel 16. ing. Also, the support of the return duct 59 is fixed to the mold portion of the floor panel 16 by bolts. Seated legs 62 are fixed to the floor panel 17.

The procedure of fitting in such a structure will be described. First, the structure is constructed by sequentially arranging the roof panel 11, the eaves panel 12, the curtain panel 13, the wind-up panel 14 and the waist panel 15, and dividing them into, for example, a roof portion and a side portion to form a block. Is joined to an underframe incorporating the floor panel 16 and a gable block is joined. After the step of each block or after the assembly is completed, an opening for inserting and fixing the various fastening bolts is formed in a mold material portion of each panel joint on the surface of the assembly using an automatic processing machine or the like. Then, the heat insulating material 52 continuous in the longitudinal direction of the vehicle body is attached to the inner surface of the structure. Then, the ceiling center support 31 in which the electric wire harness constructed by outwork is put in the mold material of the ceiling portion is fixed by the fastening bolt 41. In addition, the ceiling support 32 or the floor plate bracket 6
1 is fixed to the corresponding mold member of each panel joint with a fastening bolt or the like.

Next, when necessary wiring is pulled out from the electric wire harness and wiring is completed, one end of the ceiling interior plate 51 is hooked on the ceiling center support 31 and the other end is fixed to the ceiling side support 32. To do. Further, one end of the luggage rack 55 is hooked on the ceiling side support 32, and the other end is fixed to the mold member of the panel joint portion. Then, the upper end of the side interior material 56 is hooked on the lower part of the luggage rack 55, and the lower end of the floor support 61 is previously set.
It is fixed to the end of the floor panel 16 which has been fixed to.
The conditioned air duct 57, the blowing duct 58, and the return duct 59 are installed immediately after the heat insulating material 52 is installed. Then, the lamp 53 and the lamp cover 54 are attached to the ceiling side support 32, and the sitting legs 62 are attached to the floor panel 16.

According to such a structure, the ceiling interior plate 5
1. Various interior materials such as the luggage rack 55, the side interior plate 56, the lamp 53, and the lamp cover 54 are attached to the ceiling center support 31, the ceiling side support 32, and the fastening bolts with respect to the mold material located at the joint portion of each panel. Since it can be fixed by 41, 42, 43, etc., the strength of the fixed portion can be sufficiently secured and the reliability can be secured. That is, since the mold material in the joint portion of each panel is joined to each member constituting the panel by brazing, the load applied to the mold material can be dispersed and transmitted to the entire panel, that is, the structure. Further, since the mold material of each panel is premised on joining by welding, it has a predetermined plate thickness and is stronger than the face plate portion. Therefore, if the fittings are attached to the mold member through the various fitting supporters, sufficient strength can be secured and reliability can be improved.

By the way, since the structure constituted by the laminated panel has high rigidity of each panel itself, after the completion of the structure, by processing the installation position of the outfitting tool support to the mold material portion, the outfitting between the outfitting tool supports can be changed. The dimensional accuracy of can be secured with high accuracy. Therefore, like the ceiling interior plate 51, the luggage rack 55, and the side interior plate 56, it is very easy to align the fittings that are installed across a plurality of fitting supporters with the respective supporting members and supporting positions, And it can be done efficiently. This means that even when the interior is refurbished after a certain period of time, if the accuracy of the outfitting equipment itself is ensured, the outfitting work can be performed as easily as during production.

In the above-mentioned outfitting structure, since the necessary machining is completed at the time of manufacturing the structure, there is no need to carry out any work such as drilling or tapping along with the outfitting work.
It is possible to prevent the cleaning of chips and the occurrence of work defects. Further, since the heat insulating material 52 has a smooth inner surface formed by panels without protruding bone members or the like, it is possible to use a long continuous material in the longitudinal direction of the vehicle body. The workability can be significantly improved as compared with the structure in which the bone members are divided and arranged according to the intervals between the bone members. Further, since the heat insulating material 52 is long, the heat insulating layer is continuously formed, which leads to improvement of the heat insulating effect.

The ceiling inner plate 51 and the side inner plate 56 are provided with long holes in the screwed portions for adjusting the fixing positions in the width direction, that is, the circumferential direction of each of the inner plate. . The elongated hole is formed such that its longitudinal direction is along the width direction or the up-down direction of the vehicle body. With such a configuration, the ceiling interior plate 51 and the side interior plate 5
Since 6 is fixed by hooking one of its fixing portions, position adjustment in the longitudinal direction of the vehicle body can be easily performed. Further, the ceiling center support 31 and the ceiling side support 32
Even if there is some error in the longitudinal direction of the vehicle body, the ceiling interior plate 51 is provided with an elongated hole, so that the ceiling interior plate 51 can be easily attached. That is, each of the interior plates can adjust the fixing position to the structure in the vehicle body longitudinal direction and the direction intersecting the vehicle body longitudinal direction. Therefore, even if the dimensional accuracy of the structure itself or the interior plate, which is an outfit, is somewhat poor, it does not adversely affect the work of attaching the outfit. This is particularly effective for reclaiming work in which only outfitting is replaced.

In the above-mentioned embodiment, the fitting support tool is installed on the mold material of each panel joint part by the fastening bolts. However, the fitting support tool is installed by welding or rivets. A structure for forming a rail-shaped outfitting support portion on the mold material will be described.

The fitting support 71 has a rail-like fixed portion of the fitting, and a T-shaped joining end of the panel to the mold member. The equipment support 71
A groove is formed in the T-shaped portion so as to escape the surface bead portion of the welded portion W. Furthermore, it is considered that welding can be performed at the tip of each flange portion extending to both sides while avoiding the bead portion. ing. The outfitting is installed on the rail portion of the outfitting support 71 by using a special fastening bolt having a T-shaped head.

According to this structure, since the fittings can be fixed to the fitting support 71 while adjusting the installation position in the longitudinal direction, the positioning between the fittings can be facilitated. Become. In addition, the outfitting equipment support 71 is
Since it is attached to the surface of the structure by welding, cutting work such as drilling is not performed, so the strength of the structure is not affected, and there is no problem due to generation of cutting chips. Since the outfitting tool support 71 is made of an extruded aluminum alloy profile, and the shape of the rail portion can be arbitrarily determined, it is possible to achieve the same effects as the outfitting tool support structure of the above embodiment. Is also possible.

In the figure, the same reference numerals as those in FIG. 2 denote the same members. The outfitting tool support 72 has a substantially C-shaped cross section, and is attached to the reinforcing member 4 of the panel by rivets 73. Since the outfitting tool support 72 is rail-shaped like the outfitting tool support 71, the installation position of the outfitting tool can be easily adjusted. Further, in this structure, since the outfitting equipment support 72 is attached by the rivets 73, distortion due to welding heat input does not occur, and accurate equipment arrangement is possible.

FIG. 9 is a sectional view showing a fourth embodiment of the present invention in which a fitting support portion is formed on the laminated panel itself. In the figure, the mold material 5a installed in contact with the end surface of the core material 3 is

According to this structure, since the fitting support portions are formed on the inner surface of the structure only by joining the laminated panels by welding, the work can be simplified without any special work. You can Moreover, since various connecting means such as fastening bolts, welding or rivets are not used,
It is possible to prevent a decrease in reliability caused by factors such as work conditions and the degree of skill of the worker.

FIG. 10 is a sectional view showing a fifth embodiment of the present invention in which a fitting support portion is formed on the laminated panel itself. In the figure, the mold members 5c and 5d, which are in contact with the core member and installed at the end portions of the respective laminated panels, are fitted to each other to form a rail-shaped outfitting component support portion.
