Further, as shown in FIG.
It has a horizontal bottom piece 9 and a rising piece 10 that rises from one edge of a wide portion 9a of the bottom piece 9, and the rising piece 1
0 is wider than the width W3 of the first small beam member 3 (the bottom piece 9 is also wider than the width W3 in the example shown in FIG. 4), and at different positions in the width direction of the rising pieces 10 Attachment holes 33 for attaching the end plate 32 of the first small beam member 3 using fixing members such as bolts are provided at different positions in the width direction.

As shown in FIG. 6, the bottom piece 9 of the joint fitting 5 is wider than the width W3 of the first small beam member 3 (at this time, the rising piece 10 is wider than the width W3). Or at least mounting holes 33 for fixing the end plate 32 may be provided).

[0015] As shown in FIG.
The opposite side of each pair of the beam members 2 and each lower flange 4,
4 The bottom pieces 9 and 9 are placed on the upper surface and fixed using fixing members 34 such as bolts. At this time, the rising pieces 10, 10 of the joint fittings 5, 5 are opposed to each other with a slight distance from the beams 2, 2.

In addition, the rising pieces 10 facing each other include:
Each of the end plates 32, 32 of the first small beam member 3 is fixed by using fixing members 35, such as bolts, with the upper surfaces of the beam members 2, 2 flush with each other. Is crossed between the rising pieces 10 and 10 at right angles to the beam members 2 and 2.

In FIG. 2, two parallel first beams 3 are bridged, and in FIG. 3, one first beam 3 is bridged.

Further, since the first small beam 3 can be mounted at different positions of the rising pieces 10, the mounting position of the first small beam 3 can be adjusted conveniently, and the bottom piece of the joint fitting 5 can be adjusted. 9 can be attached to the lower flange 4 of the beam 2 by selecting the plurality of holes provided in the lower flange 4 at different positions in the longitudinal direction of the lower flange 4 of the beam 2 by using the fasteners 34. The mounting position of the first small beam 3 can be easily adjusted without using another hardware.

Further, as shown in FIG.
It is also possible to use a small beam member 11 in which the joints 5 and 5 are integrally formed in advance in a factory or the like. In such a case, the number of steps on site can be reduced, workability can be improved, and construction quality can be improved. .

Note that the small beam member 11 is
The bottom piece 9 can be attached at a different position of the lower flange 4 of the beam member 2 in the same manner as described above, so that the attachment position of the first small beam member 3 can be adjusted.

In addition, the second small beam 6 is shown in FIGS.
As shown in FIG. 5, for example, a base 40 having a substantially L-shaped cross section in which a hanging piece 39 is lowered from one side edge of a horizontal and long upper piece 37, and end plates 41, 41 fixed to both ends thereof, In FIG. 2, bolts and the like are respectively attached to the two first beams 3 and 3, and in FIG. 3, the one first beam 3 and the joint metal 42 attached to the other beams 27 are respectively provided. Is fixed using the fixing tool 43 of FIG.

The upper surfaces of the beam 2 and the other beam 27 and the first
The upper surface of the small beam member 3 and the upper surface of the second small beam member 6 are constructed so as to be flush with each other. Further, the metal joint 42 has substantially the same configuration as the metal joint 5, and thus a detailed description of the metal joint 42 will be omitted.

A region defined by such a frame member 7 and surrounded by the beam 2 (the "region" here is defined by a pair of the beams 2, 2 and another not-shown beam). The ALC floor plate 12 is supported by the frame member 7 and arranged at the position, and the upper surfaces of the beams 2 and 2 are also included in this region.

Here, since the first small beam 3 is joined to the beam 2 by the joining fitting 5 at the lower flange 4 of the beam 2, a fixing tool or the like projects from the upper surface of the upper flange 26. It does not become an obstacle when arranging the ALC floor plate 12 (the same applies to the joint metal 42 of the second small beam 6), and the upper surfaces of the beams 2, 2 and the first small beam 3, Since the upper surface of the second beam member 6 and the upper surface of the other beam member 27 are flush with each other, the ALC floor plate 12 can be easily mounted on each upper surface without causing backlash.

As shown in FIG. 1, FIG. 2 or FIG. 3, FIG. 8, FIG. 9, and FIG. 10, the ALC floor plate 12 is provided with a pair of upper surfaces of the pair of beams 2, 2 in the partitioned area. A rectangular small AL whose end is placed on the upper surface of the first beam 3
C floorboards 17 (two in FIG. 2, one in FIG. 3) and 1
The upper end of the pair of beams 2 and 2, the upper surface of the first small beam 3 and the upper surface of the other first small beam 3 (FIG. 2) or the other beam 27 (FIG. 3) Is placed and the small ALC floorboards 13, 1 divided on the upper surface of one of the second beam members 6 are divided.
3 is included.

Here, the term "split ALC floorboard" refers to a bridge between the beams 2 and 2 without being placed on the upper surfaces of the first and second beams 3 and 6. Normal (large) A passed
Compared to the LC floor panel, the ALC floor panel is reduced in size by having at least one edge supported by the first small beam member 3 and / or the second small beam member 6.

In some cases, as shown by a dashed line in FIG. 1, the end of the ALC floor plate 12 does not reach the upper surface of the beam 2 and is placed only on the upper surface of the first beam 3. Sometimes.

At least one of the small-sized ALC floorboards 13, 13, in this example, one small-sized ALC floorboard 13 on the outer wall W1 side shown in FIGS. A small ALC floor plate 15 for pipes (illustrated in FIG. 9) in which holes 14 for pipes passing through are formed.

The small ALC floor plate 15 for piping is shown in FIG.
12A to 12G, the frame member 7 may be appropriately provided in a space of, for example, about 600 mm × 1800 mm (of course, other dimensions may be used) as schematically shown in FIGS. Can be placed in

As described above, the small ALC floor boards 13 are used, and at least one of them (or two or more) is used as the small ALC floor board 15 for piping, and the small ALC floor board 15 for piping is placed in an appropriate position. , It is possible to freely set the positions of the pipes 20... According to the plan. Especially, it is not necessary to prepare various types of normal (large) ALC floor boards having different pipe positions to fit the plan, and to reduce the cost. And the degree of freedom of the plan can be improved.

If a single hole is provided with a hole for piping or the like, the strength as a whole is reduced. However, a portion where the hole for piping 14 is not necessary is a small ALC floor plate 1 having no hole for piping.
3, the strength of the floor can be sufficiently secured.

Further, a wall 16 surrounding a floor portion B on which the small ALC floor plate 15 for piping is arranged is formed. As shown in FIG. 1, the wall body 16 includes, for example, a partition panel 45 formed by attaching face materials to the front and back surfaces of a framework in which frame materials are joined.
Can be formed. Note that the wall body 16 does not necessarily have to be arranged on the outer peripheral edge of the small ALC floor panel 15 for piping. For example, the upper surface of the adjacent ALC floor panel 12 is used for reinforcing particle boards or the like, and preventing damage to the ALC floor panel. Can be erected via the face material 47 for the occupant.

In some cases, the wall 16 including the partition and the outer wall forms a small ALC floor panel 15 for piping whose strength has been reduced due to the provision of the hole 14 for piping. Since the partition B is partitioned, it is possible to prevent a load from being applied to the floor B by a person being erroneously placed on the floor B, thereby preventing the floor B from being damaged. Therefore, the space surrounded by the wall 16 can be reduced.

FIGS. 13 and 14 show examples in which the small ALC floor plate 15 for piping is arranged at different positions in FIG. 2 and the floor portion B is surrounded by a wall 16 (indicated by a dashed line).

[0035]

As described above, according to the floor structure of the present invention, the floor space surrounded by the beams is divided into small areas by the AL.
The C floor plate is supported by the frame member and arranged, and at least one small ALC floor plate is a small ALC floor plate for piping having a hole for piping. Therefore, by arranging the small ALC floor panel for piping in the frame material at an appropriate position, the position of the piping can be set relatively freely,
The degree of freedom of the plan can be increased, and the use of small-sized ALC floor boards eliminates the need to prepare a large variety of large-sized ALC floor boards having different piping positions in accordance with the plan, and can reduce costs, improve workability, and the like.

If a hole for piping is formed in one ALC plate, the strength of the entire ALC plate is reduced. However, when a small ALC floor plate for piping is used as in the present invention, the hole for piping is reduced. The part that is not formed is the normal small AL
The floor can be formed by using the C floor plate, and the strength of the floor can be sufficiently ensured, and the periphery of the small ALC floor plate for piping around the piping can be easily reinforced.

Further, in the second aspect of the present invention, when a wall surrounding the floor portion on which the small ALC floor plate for piping is arranged is formed, the wall structure reduces the strength of the small ALC floor plate for piping. It can be separated from the living room space surrounding the upper surface, and can prevent a load from being imposed on a small ALC floor plate for piping due to a person being erroneously placed on the small ALC floor plate, thereby preventing damage to the small ALC floor plate for piping. .

Further, since the small ALC floor plate for piping is small, the space surrounded by the wall can be small, and the dead space in the building can be reduced.
