An underfloor piping member 88 is buried between the underfloor space 86 below the floor 23 of the stairs 66 provided in the indoor space 22 on the lower floor component 18 side. As shown in FIG. 1, an underfloor piping member 90 is buried between the living room 44 on the lower-floor component 16 side and the lower floor 62 of the lower-floor component 18 and below the floor of the living room 70.

  Hard vinyl chloride pipes (VP pipes) are used for the underfloor piping members 88 and 90, and piping 92 and wiring 94 (see FIG. 2) are inserted into the underfloor piping members 88 and 90. . Since the configuration of the underfloor piping member 88 and the underfloor piping member 90 are substantially the same, the following description will be made on the underfloor piping member 88 as a representative thereof.

  As shown in FIG. 2, the underfloor piping member 88 has a substantially linear shape, and includes a rising portion 98A of the building foundation 98 on the lower floor component 16 and a rising of the building foundation 100 on the lower floor component 18. Part 100A, the under-floor moisture-proof concrete 112 in the under-floor space 84 on the lower-floor component 16 side, the outdoor underground 101 of the inner garage 24, and the under-floor moisture-proof concrete in the underfloor space 86 on the lower-floor component 18 side 114 buried.

  In addition, the underfloor piping member 88 is disposed with the upper end of the opening end 116 of the underfloor piping member 88 (here, the upper half of the underfloor piping member 88) exposed in the underfloor moistureproof concrete 112. The upper portion of the end 118 (here, the upper half of the underfloor piping member 88) is disposed in an exposed state.

  On the other hand, the underfloor moisture-proof concrete 112 is provided with an inclined surface (exposed portion) 112B around the open end 116 of the underfloor piping member 88, and the inclined surface 112B exposes the lower side of the open end 116. .

  In the present embodiment, the inclined surfaces 112B and 114B have been described as examples of the exposed portions formed on the underfloor moisture-proof concrete 112 and 114. However, the lower sides of the open ends 116 and 118 of the underfloor piping member 88 may be exposed. Therefore, the exposed portion need not necessarily be the inclined surfaces 112B and 114B, and may be a curved surface.

(Functions and effects of buildings and piping structures)
As described above, in the present embodiment, as shown in FIG. 2, the underfloor piping member 88 penetrates the building foundation 98 on the lower-floor component part 16 side and the building foundation 100 on the lower-floor component part 18 side, and forms a straight line. In the shape, the underfloor moisture-proof concrete 112 in the underfloor space portion 84 on the lower-floor component 16 side, the outdoor underground 101 of the inner garage 24, and the underfloor moisture-proof concrete in the underfloor space portion 86 on the lower-floor component portion 18 side 114 buried. Further, in the underfloor piping member 88, an upper portion of the open end 116 is exposed in the underfloor moisture-proof concrete 112, and an upper portion of the open end 118 is exposed in the underfloor moistureproof concrete 114.

  With the above-described configuration, in the underfloor piping member 88 of the present embodiment, when newly piping a pipe material by reforming or the like, the pipe material can be directly inserted from the open ends 116 and 118 of the underfloor piping member 88. Good workability.

  In this embodiment, since the underfloor piping member 88 is buried in the outdoor underground 101 of the inner garage 24, the underfloor piping member 88 is not exposed outside in the inner garage 24, and the Performance can be improved.

  Further, in the inner garage 24, by burying the underfloor piping member 88 in the outdoor underground 101, although not shown, compared with the case where the underfloor piping member is disposed on the outdoor ground, the mesh on the outdoor ground 102 is reduced. Since the slab concrete 104 reinforced with streaks can be directly poured, the rigidity of the outer floor in the inner garage 24 can be improved. In other words, in this embodiment, by improving the rigidity of the outer floor of the penetration portion 14 of the house 12, the penetration portion 14 can be applied as the inner garage 24.

  Also, in the outdoor space, the underfloor piping member 88 is buried in the outdoor underground 101, so that the level of the interstitial concrete 104 (external floor top 24A) is lower than when the underfloor piping member is disposed on the outdoor ground. Can be lowered.

  That is, the level difference can be increased between the levels (in the height direction) of the floors 21 and 23 of the indoor spaces 20 and 22 of the house 12 and the level of the outer floor top 24A of the inner garage 24. In the inner garage 24, by lowering the level of the outer floor top end 24A, the load on the underfloor piping member 88 is reduced, and even if the underfloor piping member 88 is a rigid polyvinyl chloride pipe, deformation or the like may occur. Problems can be avoided.

  On the other hand, in recent years, it is desired to reduce the level difference between the levels of the floors 21 and 23 of the indoor spaces 20 and 22 of the house 12 and the level of the outer floor top 24A of the inner garage 24 from the viewpoint of barrier-free. For this reason, the level of the outer floor top 24A of the inner garage 24 may be set to the upper side.

  That is, according to the present embodiment, in the inner garage 24, the degree of freedom in setting the level of the outer floor top end 24A is increased as compared with the case where the underfloor piping member is disposed on the outdoor ground. Therefore, the degree of freedom of the design plan according to the demand of the user is increased.

  Further, in the present embodiment, in the underfloor piping member 88, the underfloor moistureproof concrete 112 around the opening end 116 is provided with an inclined surface 112 </ b> B exposing the lower side of the opening end 116, and the underfloor moistureproof concrete around the opening end 118. An inclined surface 114 </ b> B that exposes the lower side of the opening end 118 is provided on the 114.

  Since the pipe 92 and the wiring 94 are inserted into the underfloor piping member 88, the inclined surfaces 112B and 114B are provided around the open ends 116 and 118 of the underfloor piping member 88, so that the underfloor piping member 88 is provided with piping. The insertion space for inserting the 92 and the wiring 94 is increased, and the workability is further improved.

  Here, when the wiring 94 is passed through the underfloor piping member 88, the wiring 94 is disposed below the underfloor piping member 88 by its own weight. Therefore, by arranging the pipe 92 on the upper side of the underfloor piping member 88, the arrangement area of the pipe 92 and the arrangement area of the wiring 94 are naturally roughly divided in the underfloor piping member 88. When a new pipe is inserted into the underfloor pipe member 88, the wiring 94 can be kept out of the way. Although not shown, the same effects as described above can be obtained when a flexible tube is used for the wiring.

  By the way, as shown in FIGS. 1 and 2, the underfloor piping member 88 is provided with an underfloor space portion 84 under the floor portion 21 of the stairs 40 provided in the indoor space portion 20 on the lower floor component 16 side of the house 12. An underfloor piping member 88 is buried between an underfloor space 86 below the floor 23 of the stairs 66 provided in the indoor space 22 on the side of the lower floor component 18. On the other hand, as shown in FIG. 1, the underfloor piping member 90 includes a living room 44 in the indoor space portion 20 on the lower floor component portion 16 side, a soil floor 62 in the indoor space portion 22 on the lower floor component portion 18 side, and a living room 70. It is buried between.

  Generally, the level (in the height direction) of the entrance 32 and the soil space 62 is set at a position lower than the level of the other floors 21 and 23 of the indoor spaces 20 and 22, and no underfloor space is provided. However, according to the present embodiment, in a region where the underfloor space is not provided, the underfloor piping member is buried in the ground, and in a region where the underfloor space is provided, a part of the opening end of the underfloor piping member is removed. By exposing, the underfloor piping member can be linearly arranged. That is, even when the underfloor piping member is buried in a region where the level in the height direction of the underfloor top end is different, the underfloor piping member can be made substantially linear.

  In general, non-living room spaces such as entrances and bathrooms require a variety of floor specifications such as concrete floors and bathroom floors. For this reason, compared with the case where the underfloor piping member is arranged on the ground in the underfloor space, in the present embodiment, the space of the underfloor spaces 84 and 86 shown in FIG. 2 can be increased, and as a result, In the non-living room space, it is possible to cope with the variety of floor specifications.

  Further, in the present embodiment, as shown in FIG. 2, in the underfloor piping member 88, for example, the upper part of the open end 116 is exposed from the underfloor moistureproof concrete 112 on the floor base surface 108, The lower part may be exposed from the underfloor moisture-proof concrete 112.

  In this case, though not shown, it is necessary to lower the level of the underfloor top end 112A as compared with the case where only the upper side of the open end 116 of the underfloor piping member 88 is exposed from the underfloor moistureproof concrete 112. In this case, the excavation depth of the building foundation needs to be increased accordingly, resulting in a longer construction period and higher cost.

  In other words, in this embodiment, as shown in FIG. 2, the lower side of the underfloor piping member 88 is buried in the underfloor moisture-proof concrete 112 of the underfloor surface 108, so that the underfloor piping member 88 is exposed to the lower side. In comparison with the case in which the floor is below the floor 112, the level of the underfloor top end 112A of the floor base surface 108 can be set to the upper side. Therefore, the excavation depth of the building can be reduced, and accordingly, the construction period can be shortened and the cost can be reduced.

  In this embodiment, as shown in FIG. 1 and FIG. 2, the underfloor piping member 88 is connected to the underfloor space 84 below the floor 21 of the stairs 40 on the side of the lower floor component 16 of the house 12. The underfloor piping member 90 is buried between the underfloor space 86 below the floor 23 of the stairs 66 on the part 18 side, and the living room 44 on the lower-floor constituent part 16 side and the soil floor 62 and the living room on the lower-floor constituent part 18 side It is buried under 70 floors.

  However, the present embodiment is not limited to this, as long as the underfloor piping member can be buried in a substantially straight line with respect to the floor surface of the building (house). For example, although not shown, in the case where a water heater is disposed in an outdoor space, the underfloor piping member is buried in the outdoor ground, and a part of the opening end of the underfloor piping member in the underfloor space portion of the lower-floor component. Make it exposed.

  In this embodiment, as shown in FIG. 2, the underfloor piping member 88 is buried substantially linearly in the underfloor moistureproof concrete 112, the outdoor underground 101 and the underfloor moistureproof concrete 114. The shape is not necessarily limited to a straight line, as long as the pipe 92 can be inserted into the member 88.

  For example, as shown in FIG. 3, the underfloor piping member 88 may be formed in a curved shape in a front view. In this case, as shown in FIG. 1, the underfloor piping member 88 is buried at a deeper position on the outdoor underground 101 side of the inner garage 24 as compared with the case where it is formed linearly. As a result, the level of the outer floor top 24A can be further reduced, and as a result, the degree of freedom in setting the level of the outer floor top 24A further increases. In this case, the pipe 92 is formed so as to have substantially the same curvature as the underfloor pipe member 88.

  Also, as shown in FIG. 3, when the underfloor piping member 88 is formed in a curved shape, the footing 98B of the building foundation 98 and the footing 100B of the building foundation 100 shown in FIG. is assumed. For this reason, in the building foundations 98 and 100, as shown in FIG. 3, by using the eccentric foundations 126 and 128 in which the inner garage 24 side is not formed, interference between the underfloor piping member 88 and the footing can be avoided. .

  Further, in FIG. 3, an example in which the underfloor piping member 88 is formed in a curved shape in a front view has been described. However, as shown in FIG. 4, the underfloor piping member 88 may be formed in a curved shape also in a plan view. It may be formed.

  As described above, the present invention has been described using one embodiment as an embodiment for carrying out the present invention. However, the present invention is not limited to such an embodiment at all, and the above-described embodiment is provided without departing from the gist of the present invention. Various modifications and substitutions can be made to the embodiment described above.
