  However, in the above-mentioned floor structure, in order to support the forelift by standing a bundle on the soil concrete, the soil is backfilled on the slope between the deep foundation or the high foundation and the general foundation. There is a need to form and this backfilling costs considerable. In addition, the underfloor space cannot be used because the underfloor space is blocked by soil.

  The present invention has been made in view of the above problems, and in a floor structure of a building in which a general foundation and a deep foundation or a high foundation are mixed, the construction cost can be reduced and the underfloor space can be effectively utilized. The purpose is to provide a floor structure of the building that can.

To achieve the above object, the floor structure of claim 1, wherein the building, in the general foundation and Fukamoto foundation and floor structures of the building that mix, partition basis with large footing provided generally basic and old law surface has a bundle erected on earth floor concrete or bundles on stones provided between the Fukamoto foundation, a floor assembly according to the Obiki supported by the bundle, a footing as the deep foundation and the outer peripheral foundation as It is characterized by the combined use of a floor set of beams erected between the deep foundation .

  The floor structure of a building according to claim 2 is the floor structure of the building according to claim 1, wherein the top end of the large pull and the top end of the base material disposed on the beam are substantially the same height. There is a feature that flooring was laid at the top of those.

  According to the floor structure of the building of claim 1 of the present invention, the floor set by the draw and the bundle and the floor set by the beam are used together, and the floor set by the beam does not need to be bundled. There is no need to return it, so that the cost can be reduced and the underfloor space formed in the part where the beam is installed can be used effectively.

  According to the floor structure of the building according to claim 2, in addition to the effect of the floor structure of the building according to claim 1, the top of the floor assembly by the draw and bundle and the floor assembly by the beam and the base material are at the same height. Because there is, the flooring can be laid on the same floor, and the degree of freedom of the layout is high.

Hereinafter, the floor structure of a building according to an embodiment of the present invention will be described with reference to the drawings. The building according to the present embodiment is planned on an inclined site, and this site is shown in FIG. In the same manner as above, the ground level has a height difference and has a slope 102.
FIG. 1 is a cross-sectional view showing a schematic configuration of a floor structure 1 of a building according to the present embodiment. As shown in the figure, an outer periphery foundation 2, a partition foundation 3, a soil concrete 4, a beam 5, and a floor panel fixing It is mainly composed of the base material 6, the large pull 7, the bundle 8, and the floor panel 9.

  The outer periphery foundation 2 transmits the load concerning the outer peripheral part of a building to the ground. Since the building according to the present embodiment is built on an inclined ground, the deep foundation 20 and the general foundation 21 are mixedly used as the outer peripheral foundation 2. The partition foundation 3 provided in the old slope 102 portion is a deep foundation, and includes a large footing 30 to resist earth pressure received from the side surface. The interstitial concrete 4 is formed by placing concrete on the ground that has been compacted between the foundations, and forms the interstices of the building.

As shown in FIG. 2, the beam 5 is an H-shaped iron horizontal member erected at a predetermined interval between the deep foundation 20, which is the outer peripheral foundation 2, and the partition foundation 3. It is one of the structural materials that form part of the floor assembly. At the end of the beam 5 on the deep foundation 20 side, an end plate 50 having substantially the same width as the beam 5 and having a substantially L-shaped cross section is fixed. Bolt holes 52 are provided in the horizontal portion 51 extending in the extending direction of the beam 5 from the upper end of the end plate 50 protruding from the upper portion of the beam 5. On the other hand, as shown in FIGS. 2 and 3, an end plate 53 having substantially the same width and height as the beam 5 is fixed to the end portion of the beam 5 on the partition base 3 side. A vertical plate 55 of a mounting bracket 54 having a substantially L-shaped cross section is fixed. Bolt holes 57 are provided in the horizontal plate 56 extending in the extending direction of the beam 5 from the upper end of the vertical plate 55 .

  The floor panel fixing base material 6 is wood having the same width as the beam 5, and is disposed along the beam 5. Since the beam 5 is made of iron, the floor panel 9 cannot be fixed to the beam 5 with a fastener such as a nail. Therefore, the floor panel 9 can be fixed by a fixing tool by disposing the floor panel fixing base material 6 made of wood on the beam 5.

  As shown in FIG. 3, the large drawing 7 is a steel large drawing and is formed in a substantially square pipe shape in cross section. Engaging recesses 70 are formed on the upper and lower sides of the left and right side surfaces corresponding to engaging claws 83 formed on a large receiving metal fitting 81 described later.

  The bundle 8 is a steel bundle that is erected on the soil concrete 10 and supports the large pull 7, and is composed of a large receiving bracket 81 and a leg portion 82. The large pulling fitting 81 is formed in a substantially U-shaped cross section so that the large pull 7 can be fitted therein, and includes an engagement claw 83 corresponding to the engagement recess 70 of the large pull 7. The leg portion 82 includes a shaft portion 85 that can be expanded and contracted in the vertical direction by turnbuckles 84 each having a reverse screw formed on the upper portion and the lower portion, a grounding plate 86 fixed to the lower end of the shaft portion 85, and the shaft portion 85. It consists of a support plate 87 fixed to the upper end. A large receiving bracket 81 is integrally welded to the support plate 87. By rotating the turnbuckle 84 provided on the leg portion 82, the height of the large receiving bracket 81 can be adjusted, that is, the height of the large pull 7 can be adjusted. A floor set between the general foundation 21 and the partition foundation 3 is formed by the large pull 7 and the bundle 8.

  In the case of the floor set made of the beam 5 and the floor panel fixing base material 6 and the floor set made of the large pull 7 and the bundle 8, the cost of the former is higher. However, when comparing the cost of the former floor set and the case where a large amount of soil is backfilled between the foundations to form the latter floor set, the former is smaller. Therefore, as shown on the left side of the partition foundation 3 shown in FIG. 1, for the part where a large amount of soil needs to be backfilled between the foundations, a floor assembly using the former beam 5 and the floor panel fixing base material 6 is used. As shown on the right side of the partition foundation 3 shown in FIG. 1, it is not necessary to backfill the soil, or the portion having a small amount of backfilling is used for the floor structure by using the floor set by the latter large pull 7 and the bundle 8. Cost can be reduced.

  As shown in FIG. 2, the floor panel 9 is a unit material formed in advance comprising a plywood 90, a joist 91, and a heat insulating material 92, and is used as a building floor material. The plywood 90 serves as a finished surface of the floor. The joist 91 is a square member that receives the plywood 90 and is bridged at right angles to the base material 6 for fixing the floor panel and the large pull 5. The heat insulating material 92 is disposed between the joists 91 under the plywood 90 to insulate the floor from below, and foamed polystyrene or the like is used.

  In order to form the building floor structure 1 configured as described above, first, the outer peripheral foundation 2 and the partition foundation 3 are provided, and the ground between the foundations is leveled and rolled. At this time, the ground level between the general foundation 21 and the partition foundation 3 is adjusted to the higher ground level in the site, and the ground level between the deep foundation 20 and the partition foundation 3 is adjusted to the lower ground level. Next, the soil concrete 4 is placed on the ground that has been rolled between the foundations.

  Then, the horizontal portion 51 of the end plate 50 of the beam 5 is placed on the top end of the deep foundation 20, and the horizontal plate 56 of the mounting bracket 54 is placed on the top end of the partition foundation 3, and the beam 5 is placed on the deep foundation 20. And spanning between the partition foundations 3 at a predetermined interval. Then, a hole is drilled in the top end of the outer peripheral foundation 20 in accordance with the bolt hole 52 of the horizontal portion 51, a hole-in anchor is driven into the hole, and the ceiling of the partition base 3 is aligned with the bolt hole 57 of the horizontal plate 56. A hole is drilled at the end, and a hole-in anchor is driven into the hole to fix the beam 5. After the beam 5 is installed, the floor panel fixing base material 6 is bolted onto the beam 5.

  On the other hand, between the general foundation 21 and the partition foundation 3, the bundle 8 is erected on the soil concrete 4 at a predetermined interval, and the large pull 7 is fitted into the large receiving metal fitting 81 of the bundle 8, and the engagement recess 70 is engaged. The claw 83 is engaged. Then, the turnbuckle 84 is rotated to adjust the height so that the large pull 7 is supported horizontally, and the height of the top edge of the large pull 7 and the height of the top edge of the floor panel fixing base material 6 are matched. After completion of the height adjustment work, the floor panel 9 is fixed and laid on the floor panel fixing base material 6 and the large pull 7 with a fixing tool. In this way, the height of the top of the floor set by the beam 5 and the floor panel fixing base material 6 and the height of the top of the floor set by the draw 7 and the bundle 8 are substantially the same. The panel 9 can be laid on the same plane, and even if different floor sets are used, there is no restriction on the floor plan and a high degree of freedom can be given to the floor plan.

  As is clear from the above description, according to the building floor structure 1 of the present embodiment, there is no need to stand the bundle 8 on the floor set by the beam 5 and the floor panel fixing base material 6. There is no need to refill the soil in the underlying foundation, thus reducing costs. In addition, a large under-floor space is formed below the beam 5. For example, the under-floor space can be effectively used by using it as a bicycle parking place or a garage from the outdoor side or as a basement from the indoor side. . In particular, in the case of a building built on a sloped site, it is necessary to refill the soil using a floor set made of the base material 6 for fixing the floor panel with the beams 5 in a portion where a large amount of the soil needs to be backfilled between the foundations. By using a floor set of the large draw 7 and the bundle 8 in a portion where there is no or a small amount to be backfilled, the cost for the floor structure can be suppressed.

  In the present embodiment, the case where the bundle 8 is erected on the soil concrete 4 placed between the general foundation 21 and the partition foundation 3 has been described. However, instead of the soil concrete 4, a bundle stone is placed on the ground. The bundle 8 may be erected on it. Moreover, although what mixed the deep foundation 20 and the general foundation 21 was used for the outer periphery foundation 2 of the building built in the site which has an inclination, as shown in FIG. 6, the partition foundation 3 built on a flat ground is used as the deep foundation. The present invention can also be applied to the case where the floor under the partition foundation 3 is used as a basement.

  Next, another embodiment of the present invention will be described. In this embodiment, as shown in FIG. 4, instead of the floor panel fixing base material 6 described above, the large pull 7 is used as a base material and is fixed onto the beam 5 using a fixing bracket 10. Other configurations are the same as those in the previous embodiment, and a description thereof will be omitted.

As shown in FIG. 6 , the fixing bracket 10 is manufactured by bending a single steel plate, and includes a body portion 11, a beam locking portion 12, and a large pulling fixing portion 13. . The trunk portion 11 is slightly wider than the beam 5, and has a substantially I shape in the extending direction of the beam 5 due to the bending of the large pull fixing portion 13, and is fixed to the beam 5. Bolt holes 14 for this purpose are provided at a total of four locations, two at each of the front and rear of the body portion 11 divided into approximately three equal parts in the longitudinal direction. The beam locking portion 12 is a portion obtained by bending the front and rear sides of the body portion 11 into approximately three equal parts in the longitudinal direction so as to be vertically downward about the thickness of the upper flange 58. When the fixing bracket 10 is placed on the beam 5, these four beam locking portions 12 allow the fixing bracket 10 to fit into the upper flange 58 of the beam 5, thereby preventing the lateral displacement of the fixing bracket 10. 14 and a bolt hole (not shown) provided in the upper flange 58 can be easily matched. Further, the large pull fixing portion 13 is a portion in which both sides of the center of the body portion 11 divided into approximately three equal parts in the longitudinal direction are bent upward by about 4 cm, and the screw hole 15 corresponds to the two large pull fixing portions 13. Two are provided at the top. The distance between the two large pull fixing portions 13 is preferably slightly larger than the width of the large pull 7, so that the large pull 7 can be easily fixed between the two large pull fixing portions 13.

Moreover, in this Embodiment, as shown in FIG. 5 , the end plate 53 fixed to the edge part of the partition base 3 side of the beam 5 is the same as the end plate 50 fixed to the edge part of the deep foundation 20 side. In addition, the horizontal portion 59 having a substantially L-shaped cross section and extending from the upper end of the end plate 53 protruding from the top of the beam 5 in the extending direction of the beam 5 is provided with a bolt hole (not shown), 54 is not fixed. Thereby, the position of the top end of the large drawing 7 fixed on the beam 5 using the fixing bracket 10 and the large drawing 7 supported by the bundle 8 is matched.

  In order to form the above-described configuration, the fixing bracket 10 is disposed within a predetermined interval on the arranged beam 5, and the fixing bracket 10 is beamed by the bolt 16 in the bolt hole (not shown) of the bolt hole 14 and the upper flange 58. 5 to fix. Then, the large pull 7 is passed between the two large pull fixing portions 13 of the fixing bracket 10, and the large pull 7 is fixed to the large pull fixing portion 13 with a fixing tool 17 such as a screw in the screw hole 13. Thus, since it fixes with the fixing tool 17 which is easy to handle, the height adjustment of the top end of the large drawing 7 is easy.

  As is clear from the above description, according to the building floor structure 1 of the present embodiment, in addition to the effects of the previous embodiment, a large steel plate is used instead of the wooden floor panel fixing base material 6. By using the pull 7 as a base material, it is possible to prevent the base material from rotting. Further, since the large pull 7 is fixed from the screw hole of the fixing bracket 10 using a fixing tool such as a screw, the height adjustment of the top end of the large pull 7 is easy.

  The present invention is applicable to a building in which a deep foundation or a high foundation and a general foundation are mixed.
