As shown in FIGS. 2 to 6, the floor assembly 10 includes a flat upper panel 21, a floor slab 22, a flat lower panel 23 vertically facing the upper panel 21, and a front frame 26. have. In the floor assembly 10 of this example, two upper panels 21 and two lower panels 23 are provided. A plurality of alignment holes 21 a are formed in the upper panel 21 for alignment with the floor slab 22 and the front frame 26 . Similarly, a plurality of alignment holes 23a are formed in the lower panel 23 for alignment with the floor slab 22 and the front frame 26.

Floor slab 22 is arranged between upper panel 21 and lower panel 23. Further, the floor slab 22 is adhesively fixed to the upper panel 21 and the lower panel 23 using an adhesive. The front frame 26 is arranged on the front side of the upper panel 21 where the door section 13 is installed. The front frame 26 is then fixed to the upper panel 21. A door sill that movably supports the door portion 13 is fixed to the front frame 26.

As shown in FIGS. 4 and 5, the floor slab 22 includes a plurality of intermediate structures 24 and two end structures 25. The intermediate structure 24 and the end structure 25 have a substantially C-shaped cross section when cut in the vertical direction. The intermediate structure 24 and the end structure 25 are elongated members extending along the longitudinal direction orthogonal to the up-down direction of the upper panel 21 and the lower panel 23. Moreover, the intermediate structures 24 are arranged side by side along the width direction orthogonal to the up-down direction of the upper panel 21 and the lower panel 23. The end structures 25 are arranged at both ends of the plurality of intermediate structures 24 in the width direction.

The intermediate structure 24 has a joint surface 24a, a pair of reinforcing portions 24b, and a bent portion 24c. The joint surface 24a is formed into a substantially flat plate shape. An identification hole 24e is formed at one end of the joint surface 24a in the longitudinal direction. By providing the identification hole 24e, the front and rear of the intermediate structure 24 can be identified. Note that an identification hole may also be provided at the other longitudinal end of the joint surface 24a to identify the front and back.

Reinforcement portions 24b are bent approximately perpendicularly at both ends of the joint surface 24a in the width direction. The reinforcing portion 24b is bent approximately perpendicularly from the end of the joint surface 24a and extends in the up-down direction. A bent portion 24c is formed at the end of the reinforcing portion 24b on the opposite side from the joint surface 24a. The bent portion 24c is bent approximately perpendicularly from the reinforcing portion 24b and protrudes in the width direction. Further, the bent portion 24c protrudes from the end of the reinforcing portion 24b toward the side opposite to the joint surface 24a.

A floor slab side alignment hole 24d is formed in the joint surface 24a and the bent portion 24c. By driving rivets 31 into the floor side alignment holes 24d provided in the intermediate structure 24 and the alignment holes 21a and 23a provided in the upper panel 21 and lower panel 23, the intermediate structure relative to the upper panel 21 and the lower panel 23 is 24 can be aligned.

Further, the bent portion 24c of the intermediate structure 24 is placed on the lower panel 23. The bent portions 24c of two adjacent intermediate structures 24 are arranged close to each other. Further, the upper panel 21 is placed on the joint surface 24a of the intermediate structure 24.

Note that the intermediate structure 24B disposed at the dividing position 33 between the upper panel 21 and the lower panel 23 in the plurality of intermediate structures 24 is arranged with its vertical direction reversed. That is, the joint surface 24a of the intermediate structure 24B is placed at the dividing position 33 of the lower panel 23. Then, the upper panel 21 is placed on the bent portion 24c of the intermediate structure 24B. The two lower panels 23 are connected by this intermediate structure 24B. As a result, by arranging the intermediate structure 24 upside down, the lower panels 23 can be easily connected, and the division positions of the lower panels 23 can be easily designed.

Next, the end structure 25 will be explained.
Like the intermediate structure 24, the end structure 25 has a joint surface 25a, a pair of reinforcing parts 25b, and a bent part 25c. The joint surface 25a is formed into a substantially flat plate shape. The joint surface 25a is placed on the lower panel 23. Reinforcement portions 25b are bent approximately perpendicularly at both ends of the joint surface 25a in the width direction. The reinforcing portion 25b is bent approximately perpendicularly from the end of the joint surface 25a and extends in the up-down direction. A bent portion 25c is formed at the end of the reinforcing portion 25b opposite to the joint surface 25a.

The bent portion 25c is bent approximately perpendicularly from the reinforcing portion 25b and protrudes in the width direction. Of the two bent portions 25c, the bent portion 25c disposed on the inner side in the width direction projects toward the side opposite to the joint surface 25a. On the other hand, of the two bent portions 25c, the bent portion 25c disposed on the outer side in the width direction projects toward the joint surface 25a side, that is, toward the inside of the floor assembly 10.

Similarly to the intermediate structure 24, floor slab side alignment holes 25d are formed in the joint surface 25a and the bent portion 25c. By driving rivets 31 into the floor side alignment holes 25d provided in the end structure 25 and the alignment holes 21a and 23a provided in the upper panel 21 and lower panel 23, the end portions relative to the upper panel 21 and the lower panel 23 are driven. Alignment with the structure 25 can be performed.

The joint surface 25a of the end structure 25 is placed on the lower panel 23, and the upper panel 21 is placed on the bent portion 25c.

7 and 8 are perspective views showing the longitudinal ends of the floor assembly 10. FIG.
As shown in FIGS. 7 and 8, the length in the longitudinal direction of the intermediate structure 24 and the end structure 25 constituting the floor slab 22 is set shorter than the length in the longitudinal direction of the upper panel 21 and the lower panel 23. has been done. Therefore, both longitudinal ends of the upper panel 21 and the lower panel 23 extend outward in the longitudinal direction from both longitudinal ends of the floor slab 22 (intermediate structure 24 and end structure 25). .

Furthermore, the bent portions 25c disposed on the outside in the width direction of the end structure 25 protrude toward the inside in the width direction. Therefore, both ends of the upper panel 21 and the lower panel 23 in the width direction protrude outward in the width direction from the ends of the floor slab 22 (end structure 25) in the width direction.

2. Example of Assembly Work for Floor Assembly Next, an example of work for assembling the floor assembly 10 having the above-described configuration will be described.

First, the operator sets the number of intermediate structures 24 to be installed in accordance with the widthwise lengths of the upper panel 21 and lower panel 23 of the floor assembly 10. Then, as shown in FIG. 4, the intermediate structure 24 and the end structure 25 are placed on the lower panel 23. Note that the intermediate structure 24B disposed at the dividing position 33 of the lower panel 23 is disposed with its vertical direction reversed. Note that the adhesive 40 is applied to the bent portion 24c of the intermediate structure 24, the joint surface 24a of the intermediate structure 24B, and the joint surface 25a of the end structure 25.

Then, by driving rivets 31 into the alignment holes 23a and the floor plate side alignment holes 24d and 25d, the lower panel 23 is aligned with the intermediate structures 24 and 24B and the end structure 25. Next, the adhesive 40 is applied to the joint surface 24a of the intermediate structure 24, the bent portion 24c of the intermediate structure 24B, and the bent portion 25c of the end structure 25. Then, the upper panel 21 is placed on the intermediate structures 24, 24B and the end structure 25, and the rivets 31 are driven in and aligned.

Next, by pressing the upper panel 21, the floor slab 22, the upper panel 21, and the lower panel 23 are pressure-bonded with the adhesive 40. This completes the assembly work of the floor assembly 10. Note that the front frame 26 may be fixed to the upper panel 21 in advance, or the front frame 26 may be fixed to the upper panel 21 after the upper panel 21, the lower panel 23, and the floor slab 22 are fixed.

In this way, according to the floor assembly 10 of this example, the floor slab 22, the upper panel 21, and the lower panel 23 are fixed using the adhesive 40. Thereby, the number of places where the floor slab 22, the upper panel 21, and the lower panel 23 are fastened and fixed can be reduced. As a result, the burden of forming fastening holes in the floor slab 22, upper panel 21, and lower panel 23 and the work of fastening and fixing can be reduced, and the work of assembling the floor assembly 10 can be simplified. Can be done.

Next, with reference to FIGS. 9 and 10, a state in which the floor slab 22, the upper panel 21, and the lower panel 23 are crimped and fixed using the adhesive 40 will be described.
9 and 10 are explanatory diagrams showing the crimping operation of the floor slab 22, the upper panel 21, and the lower panel 23. The floor slab 122 shown in FIG. 9 shows an example in which the upper panel 21 and the lower panel 23 have the same length in the width direction and the longitudinal direction, and FIG. 10 shows the floor slab 22 of this example. .

As shown in FIGS. 9A and 10A, an adhesive 40 is applied to the entire surface of the floor slabs 122 and 22 facing the upper panel 21 and the lower panel 23 before the pressure bonding. When the length of the floor slab 122 is the same as that of the upper panel 21 and the lower panel 23, the adhesive 40 will not touch the edges of the upper panel 21 and the lower panel 23 when crimped, as shown in FIG. 9(b). Get out of the club. There was a possibility that this protruding adhesive material 40 would adhere to other components other than the floor slab 22, the upper panel 21, and the lower panel 23.

On the other hand, as described above, the length of the floor slab 22 of this example in the longitudinal direction and the width direction is set shorter than that of the upper panel 21 and the lower panel 23. The ends of the upper panel 21 and the lower panel 23 extend outward from the ends of the floor slab 22. Therefore, as shown in FIG. 10(b), when pressure bonding is performed, the adhesive material 40 protruding from the floor slab 22 is contained within the upper panel 21 and the lower panel 23. Thereby, the adhesive material 40 can be prevented from protruding from the ends of the upper panel 21 and the lower panel 23. As a result, the adhesive 40 can be prevented from adhering to other parts.

Further, the difference in length between the end portions of the floor slab 22, the upper panel 21, and the lower panel 23 is set according to the amount of protrusion of the adhesive 40 from the floor slab 22. That is, the difference in length between the end portions of the floor slab 22, the upper panel 21, and the lower panel 23 is set to be larger than the amount of the adhesive 40 protruding from the floor slab 22. Thereby, it is possible to reliably prevent the adhesive material 40 from protruding from the ends of the upper panel 21 and the lower panel 23 during the crimping operation.

Note that the present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the gist of the invention as set forth in the claims.

In addition, although words such as "parallel" and "orthogonal" are used in this specification, these do not mean strictly "parallel" and "orthogonal", but include "parallel" and "orthogonal". , and may also be in a "substantially parallel" or "substantially perpendicular" state within the range where the function can be achieved.
