Detailed ways

Below, embodiment of the present utility model is described with reference to accompanying drawing.

Example 1

First, the basic structure of the floor structure of the wooden building of this invention is demonstrated with reference to FIGS. 1-3.

In the wooden building 1 , girders and girders are connected to form a rectangular assembly to form a floor structure surface. The girder is a horizontal erection member that is structurally directly connected to the main column to form a frame and receives the load from the girder. Small beams are horizontal erection members joined to girders or columns to support joists, floor coverings (Japanese: under-bed materials), etc. The girders and girders are joined by means of corbel metal.

In the floor structure surface shown in FIG. 1 , the above-mentioned girders and girders 22 are joined so as to align with the heights of the upper surfaces of the girders and girders. A plurality of small beams 22 are arranged at predetermined intervals on the floor structure surface. Between these small beams 22 , a plurality of joists are bridged at constant intervals in a direction perpendicular to the small beams 22 . A floor underlayment is arranged on the floor structure surface. The composite board 32 for the structure or a plate similar to the composite board 32 for the structure is used as the bottom laying material of the floor. The flooring material may be arranged on the upper surface of the joists erected between the girders 22, but as shown in FIG. 1, the floor member under the board may be integrated with the joists 24.

In the illustrated form, the structural composite panel 32 which is a floor underlay material is formed into a panel structure and used as a floor panel (Japanese: bed panel) 30 . The floor panel 30 is formed by installing joists 24 made of wooden square bars at constant intervals on one side of a rectangular structural composite panel 32 , thereby simplifying on-site work.

On the side surfaces of the small beams 22 , groove-shaped corbel metal fittings 71 for supporting the joists 24 are installed corresponding to the intervals of the joists 24 . These corbel metal fittings 71 are installed at height positions such that the upper surface of the supported joists 24 and the upper surface of the girder 22 are on the same plane.

The floor panel 30 falls between the girders 22 arranged parallel to each other and the side surfaces of the girders 22 . At this time, the floor panel 30 is fixed in such a manner that, as shown in FIG. The floor panels 30 are fixed by fitting each joist 24 to the corbel metal 71 . The structural composite board 32 is fixed to the small beam 22 with nails, screws, or the like. A floor covering is laid on the upper surface of the structural composite panel 32 . Moreover, the ceiling member 41 is laid on the lower surface of the girder 22 to form a top surface, and the girder 22 and the joist 24 are hidden.

Thereby, the upper surface of the joist 24 and the upper surface of the girder 22 are formed in the same plane. The upper surfaces of the joists 24 and the upper surfaces of the girders 22 constitute a floor structure surface on which a floor underlayment (structural composite board 32 ) is arranged. In addition, the structural composite panel 32 is structurally integrated with the girder 21 and the small girder 22 constituting the floor structural surface. As a result, the in-plane shear strength of the structural composite panel 32 can be effectively exhibited, and the rigidity of the floor structure surface with respect to yawing and the like can be improved.

In addition, the case where the upright column 27 is erected on the floor structure surface of this type will be described. As shown in FIG. The leg fitting 73 is, for example, a member in which a tenon tube (Japanese: ほぞパイプ) 731 and a flat plate-shaped joint plate 732 joined to one end of the tenon tube 731 are integrally welded into a shuttlecock board (Japanese: Hana board). ) shaped components. The leg metal fitting 73 has a plurality of pin holes through which driving pins and bolts penetrate.

As shown in FIG. 3 , the leg fittings 73 are provided in such a manner that the tenon tube 731 is inserted into the tenon hole formed in the small beam 22 (or girder), so that the joint plate 732 protrudes from the upper surface of the small beam 22 . The leg fitting 73 is joined to the small beam 22 by a driving pin (not shown) or the like.

The structural composite panel 32 is placed on the small beam 22 in a state where the edge portion of the structural composite panel 32 overlaps approximately half of the beam width of the small beam 22 . More specifically, the structural composite panel 32 is placed on the girder 22 in a state where the center of the material of the girder 22 is withdrawn from the material center of the girder 22 by half the thickness of the joining plate 732 . Since the joining plate 732 is a relatively thin plate, the edge of the structural composite plate 32 can be placed very close to the material center of the beam 22 even if no notch is provided at the edge of the structural composite plate 32 .

In this way, the structural composite plate 32 is placed on the upper surface of the girder 22 , and the upright column 27 is joined to the joint plate 732 protruding from the structural composite plate 32 . A slit 271 is formed at the lower end of the column 27 , and the column 27 is formed with a plurality of pin holes penetrating the slit 271 . By inserting the joining plate 732 into the slit 271 , the column 27 is erected on the structural composite panel 32 . Then, driving pins (or bolts) 81 are inserted into the pin holes from the side of the upright 27 to integrally couple the upright 27 and the leg metal 73 .

Example 2

Next, the floor structure of the wooden building of Example 2 is demonstrated with reference to FIGS. 4-6.

In addition, in the description of each of the following embodiments, the same reference numerals are assigned to the constituent members already mentioned, and detailed description thereof will be omitted.

In this Example 2, the ALC board 34 is mounted on the floor structure surface, and the floor underlayment material and the floor surface material are installed on the ALC board 34 .

As shown in FIG. 4 , an ALC panel 34 serving as a ground floor (Japanese: slab panel) is placed on a floor structure surface composed of girders 21 and small girders 22 . The upper surface of the girder 21 is at the same height as the upper surface of the small beam 22 .

The lengthwise dimension of the ALC plate 34 is substantially equal to the pitch of the small beams 22 . Both ends in the longitudinal direction of the ALC plate 34 are placed on the upper surface of the small beam 22 . In addition, small screws 85 are driven into both ends in the longitudinal direction of the ALC board 34, and the ALC board 34 is fixed to the horizontal erection member.

As shown in FIG. 5 , a reinforcing rib 342 is buried at a position about 15 to 30 mm inward of the longitudinal end of the ALC plate 34 . A small screw 85 is driven into the inner side of the reinforcing rib 342 .

In addition, as shown in FIG. 4 , bolts (Japanese: コツター) 35 are driven into multiple places on the long sides of the adjacent ALC boards 34 . The plug 35 is a hollow or solid cylindrical member. Each plug 35 is fitted into and fixed in an unillustrated columnar hole straddling adjacent ALC plates 34 . The plug 35 prevents the displacement of the ALC board 34 due to the action of the in-plane shear force applied to the ALC board 34 , and the occurrence of seam displacement on the long sides. Accordingly, the ALC sheet 34 can secure high in-plane shear strength and in-plane shear rigidity.

On the upper surface of the ALC board 34, the hard fiber board 36 which is a floor underlayment material is arrange|positioned. The hard fiberboard 36 is a single-layer or multi-layer board material obtained by applying an adhesive to wood chips, chips, etc., and performing thermocompression molding. Each hard fiberboard 36 straddles a plurality of ALC sheets 34 and is arranged in a direction perpendicular to the ALC sheets 34 . A part of the seam of the long side of the hardboard 36 is aligned with a seam of the short side of the ALC board 34 , and a part of the seam of the short side of the ALC board 34 is aligned with the seam of the long side of the hardboard 36 . These hard fiberboards 36 are uniformly driven with small screws 85 to be fixed on the ALC board 34 . Since the ALC board 34 has the rib 3b at the end, it is not easily damaged even if an in-plane shearing force acts by driving the screw 85 into the end.

The ratio of the length to the width of the ALC plates 34 is large, so under the action of the in-plane shear force, the displacement between the ALC plates 34 at the joints of the long sides is likely to be greater than that at the joints of the short sides. To solve this problem, in this embodiment, the hard fiberboard 36 is used to constrain the ALC boards 34 adjacent in the width direction, so as to prevent the joints of the long sides from being misaligned. That is to say, two hard fiberboards 36 are used for every four ALC boards 34 to form an integrated structure. Thus, when an in-plane shear force is applied to the ALC plate 34, the ALC plate 34 and the hard fiberboard 36 are constrained to each other out of the plane to prevent dislocation at the seam, thereby ensuring a high resistance to in-plane shear. Endurance and rigidity of force.

In addition, the ALC board 34 and the hard fiber board 36 can be fixed and integrated by simple construction using screws 85 and the like, and a floor structure excellent in both in-plane shear strength and in-plane shear rigidity can be formed. The in-plane shear force acting on the ALC sheet 34 spreads on the ALC sheet 34 in a planar manner, and then is transmitted from the ALC sheet 34 to the hard fiberboard 36 from one surface to the other. As a result, the shear stress spreads in a planar manner, and it is possible to prevent a large stress from acting locally.

In this way, in the floor structure of the second embodiment, the in-plane shear strength of the hard fiberboard can be effectively exerted, and various components can be easily connected, and it is not easily affected by dimensional errors and installation errors.

In addition, when the wooden structure building 1 is a building with two or more floors, as shown in FIG. ) 26 engagement. The column 27 is erected on the upper surface of the girder 21 by means of a tubular joint metal member 75 . Notches 341 corresponding to the outer shapes of these columns 26 and 27 are formed in the ALC board 34 and the hard fiberboard 36 arranged in contact with the through columns 26 and the upright columns 27 .

Example 3

The floor structure of the wooden structure building of Example 3 is demonstrated with reference to FIG. 7. FIG.

In the floor structure of this embodiment, on the floor structure surface composed of multiple girders 21 and multiple small beams 22 arranged in parallel, the height of the upper surface of the small beams 22 is lower than the height of the upper surface of the girders 21 .

As shown in FIG. 7 , the upper surface of the small beam 22 is lower than the upper surface of the girder 21 by a height equivalent to the thickness of the ALC plate 34 . That is, the girder 21 is provided on the same plane as the upper surface of the ALC panel 34 .

The ALC panel 34 and the girder 21 have a positional relationship such that, on one side of the girder 21 , the end side (Japanese: small mouth surface) of the ALC panel 34 contacts the side of the girder 21 . In addition, on the other side of the girder 21 , a gap 37 of about 20 mm is provided between the side and the end side of the ALC panel 34 . The dimensional errors and construction errors of the ALC board 34 , the girder 21 , and the small beam 22 can be adjusted by using the gap 37 .

Grooves 343 are formed at joints between the long sides of adjacent ALC plates 34 . Mortar 345 is filled in this tank 343 . The mortar 345 filled in the groove 343 connects the adjacent ALC panels 34 and acts to close gaps that are poor in sound insulation and fire resistance. In addition, the ALC board 34 can be picked up by hanging the hands in the groove 343, so the setting operation of the ALC board 34 is easy, and when the ALC board 34 is dropped on the upper surface of the small beam 22, the ALC board 34 can be prevented from being damaged. damage. On the upper surface of the ALC board 34 and the upper surface of the girder 21, the structural composite board 32 is placed across the joint portion of the ALC board 34, and the structural composite board 32 is fixed on the above-mentioned by nailing or the like. On the surface. It is also possible to fix the structural composite board 32 by using nails and vinyl acetate adhesives in combination, so that a slight height difference between the ALC board 34 , the girder 21 and the structural composite board 32 can be eliminated.

Example 4

Next, the floor structure of the wooden building of Example 4 is demonstrated with reference to FIGS. 8-10.

In the floor structure of Embodiment 4, the height of the upper surface of the small beam 22 is lower than the height of the upper surface of the girder 21 . In addition, the height of the upper surface of the ALC board 34 arranged on the floor structure surface is higher than the height of the upper surface of the girder 21 .

As shown in FIG. 8 , four ALC panels 34 are arranged so as to fall in the direction perpendicular to the small beams 22 on the upper surface of the small beams 22 erected between the girders 21 . The dimension in the longitudinal direction of the ALC plate 34 is approximately equal to the pitch of the small beams 22 . In addition, both ends in the longitudinal direction of the ALC plate 34 are fixed to the upper surface of the small beam 22 with screws 85 or the like. At the seams of the long sides of the ALC panels 34, plugs 35 are arranged as seam displacement prevention members. The plug 35 prevents the long sides of the ALC sheet 34 from being dislocated due to the in-plane shear force acting on the ALC sheet 34 .

In addition, when the four ALC panels 34 disposed between the girders 21 and 21 receive an in-plane shear force, openings tend to be formed at the joints of the long sides. Therefore, in this embodiment, a restricting member is arranged to prevent the opening at the seam.

As the constraining member, for example, a board 51 made of hardboard can be used. The plate material 51 is formed slightly shorter than the length of the ALC plate 34 . The plate material 51 falls between the ALC plates 34 and is arranged on the upper surface of the girder 21 . The plate 51 is fixed to the girder 21 by driving small screws 85 into the girder 21 from the upper surface of the plate 51 . In addition, the plate material 51 may also be fixed to the girder 21 by using an adhesive.

Since the plate 51 is slightly shorter than the length in the longitudinal direction of the ALC plate 34, a lever type nail remover and a jack (Japanese) can be inserted between the long side of the ALC plate 34 (the part not in contact with the plate 51) and the crossbeam 21. : jatsuki) etc. In addition, the plate material 51 can be fixed to the girder 21 in a state where the four ALC plates 34 are pressed in close contact with each other. In addition, it is preferable not to arrange the plate material 51 across a plurality of ALC plates 34 . Accordingly, it is possible to easily cope with dimensional errors of the ALC board 34 .

As shown in FIG. 9 , at the connection portion of the ALC panel 34 to the girder 21 , the end side surface of the ALC panel 34 is in direct contact with one side surface of the girder 21 . A gap 37 is provided between the ALC plate 34 and the plate material 51 . In addition, on the side surface opposite to the girder 21 , the end side surface of the other ALC panel 34 is arranged with a gap 37 between the girder 21 and the other ALC panel 34 abuts against the side surface of the plate 51 . Accordingly, the horizontal displacement of the ALC plate 34 can be restrained by the plate material 51 . In addition, the gap between the girder 21 and the ALC board 34 allows for dimensional errors and construction errors of the ALC board 34 and the girder 21 .

In addition, as shown in FIG. 10 , a plate material 51 may be provided as a restraining member. In this case, the upper surface of the end portion of the ALC plate 34 adjacent to the girder 21 is cut to form the concave portion 346 . A plate 51 as a restraining member is placed across the upper surface of the girder 21 and the concave portion 346 of the ALC plate 34 , and the plate 51 is fixed to the girder 21 and the ALC plate 34 with screws 85 . Thereby, the horizontal position of the ALC board 34 can be restrained.

In addition, grooves 343 are formed at joints between the long sides of adjacent ALC plates 34 . Grout 343 is filled with mortar 345 to connect ALC boards 34 to prevent gaps. In addition, a threaded circular pipe (not shown) may be driven into the grooves 343 of the ALC plates 34, and mortar may be filled to integrally connect the ALC plates 34 to each other. A rebar is passed into the round tube portion of the threaded round tube, preventing the ALC plate 34 from rotating.

As shown in FIG. 10 , at the connecting portion between the ALC board 34 and the girder 21 , the end side of the ALC board 34 abuts against one side of the girder 21 . A gap 37 is provided between the ALC plate 34 and the plate material 51 on the upper surface of the girder 21 . In addition, on the side surface on the opposite side of the girder 21, a gap 37 is provided between the side surface and the end side surface of the other ALC panel 34, and the gap 37 is closed so as to straddle the concave portion 346 of the girder 21 and the ALC panel 34. Sheet 51. The aforementioned gap 37 allows for dimensional errors and construction errors of the ALC panel 34 and the girder 21 .

In addition, it is preferable that the strength of the board 51 is higher than that of the ALC board 34. In addition to hard fiberboard, the board 51 can also be made of wood materials such as composite boards, cement materials such as stone boards, calcium silicate boards, plastic materials or Appropriately select from metal-based materials and the like. In addition, as the constraining member of the ALC plate 34, in addition to the above-mentioned plate material 51, for example, an angle steel or the like may be used.

Next, the floor structure of the wooden building of Example 5 is demonstrated with reference to FIG.11 and FIG.12.

In the present embodiment, a wooden support 61 is arranged parallel to the girder 21 on the side surfaces of the girder 21 . The support 61 is a support member that supports the ALC board 34 .

As shown in FIG. 11 , the upper surface of the girder 21 and the upper surface of the small beam 22 are formed on the same plane to form a floor structure surface. In addition, the ALC plate 34 is fitted between the above-mentioned large beam 21 and the small beam 22 , and the support 61 supports both ends of the lower surface side of the ALC plate 34 . Both ends in the longitudinal direction of the ALC board 34 are placed on the supports 61 .

The supporting member 61 is made of a square bar with a rectangular cross-section. In addition, the supporting member 61 can also be a trapezoidal square bar whose upper width is greater than the lower width. In the illustrated form, the supporting member 61 is nailed and fixed on the main beam 21 and the small beam 22 . In addition, the support 61 is mounted so that the upper surface of the support 61 is lower than the upper surface of the girder 21 by a dimension corresponding to the thickness of the ALC board 34 .

The dimension in the longitudinal direction of the ALC plate 34 is set to be shorter than the distance between the large beams 21 and the small beams 22 or the distance between the small beams 22 by a predetermined dimension. Thus, as shown in FIG. 12 , gaps 37 are provided between the longitudinal ends of the girder 21 and the ALC plate 34 and the longitudinal ends of the small beam 22 and the ALC plate 34 . In addition, the ALC board 34 is arranged so that the upper surface is on the same plane as the upper surface of the girder 21 and the upper surface of the small beam 22 .

A plurality of structural composite panels 32 are placed on the upper surface of the ALC panel 34 , the upper surface of the girder 21 , and the upper surface of the small beam 22 . Use nails 83 to fix the structural composite board 32 on the upper surface of the girder 21 or the upper surface of the small beam 22 , and use small screws 85 to fix the structural composite board 32 on the upper surface of the ALC board 34 .

As shown in FIG. 11 , the structural composite board 32 is also nailed to the ALC board 34 with small screws 85 along the longitudinal direction at the central portion of one structural composite board 32 . The same notch 361 as the notch shown in FIG. 6 is provided on the structural composite plate 32 abutted against the through post 26 , and the through post 26 passes through the notch 361 in an uninterrupted manner.

In this way, the structural composite panels 32 are fixed to the same ALC board 34 near the long side seams, and the structural composite panels 32 are fixed to the same girder 21 or small beam 22 near the short side seams. Therefore, it is possible to suppress the joint misalignment that occurs between adjacent structural composite panels 32 to be small. Thereby, a plurality of structural composite panels 32 can be arranged integrally, and excellent shear strength and shear rigidity can be exhibited.

Example 6

Next, a floor structure of a wooden building according to Embodiment 6 will be described with reference to FIG. 13 . In this embodiment, an example in which an angle steel is used as the supporting member of the ALC panel 34 is shown.

As shown in FIG. 13 , on the side surfaces of the girder 21 and the small beam 22 , a long support member 63 made of angle steel with an L-shaped cross section is installed. Make the upper surface of the girder 21, the small beam 22 and the upper surface of the ALC board 34 supported by the support 63 substantially on the same plane, and use the small screw 85 to fix the support 63 on the side of the girder 21, the small beam 22 . Instead of the screw 85, it may be fixed using a nail, an anchor (Japanese: アンカ一), a bolt, or the like.

In addition, in the illustrated form, the planar intermediate member 38 is laid on the upper surface of the girder 21 , the upper surface of the small beam 22 , and the upper surface of the ALC panel 34 . To adjust unevenness and improve sound insulation, for example, asphalt slabs can be used as intermediate member 38 . In addition, in order to improve the sound insulation, it is also possible to effectively increase the weight by adding a weight-increasing material composed of powdery materials such as lead and iron to the asphalt board. In addition, as the intermediate member 38 , a member having a thickness of about 2 to 50 mm made of a ceramic material such as rubber sheet, nonwoven fabric, cement material, calcium silicate, or ceramic can be used. The structural composite plate 32 is placed on the upper surface of the intermediate member 38 , and the structural composite plate 32 is fixed to the intermediate member 38 with screws 85 . By adjusting the thickness dimension of the intermediate member 38, the height of the floor surface can be easily adjusted.

In this embodiment, compared with the case of the above-described Embodiment 5, only an amount corresponding to the thickness of the support member 63 protrudes from the lower surface side of the ALC plate 34 . Therefore, a large space without protruding parts can be formed under the ALC plate 34, and a sufficient space for piping and the like can be ensured.

In addition, it is preferable to ensure a gap of about 10 to 20 mm between the girder 21, the girder 22, and the side surface of the ALC plate 34, so that dimensional errors and construction errors of the ALC plate 34, the girder 21, etc. can be tolerated.

In addition, the intermediate member 38 interposed between the structural composite panel 32 and the ALC panel 34 is preferably a member having at least one of the following functions, that is, to adjust the slight unevenness generated on the surface of the ALC panel 34. function, the sound insulation performance against impact sound, airborne sound, etc., and the increase or decrease adjustment function of in-plane shear rigidity.

Example 7

Next, the floor structure of the wooden building of Example 7 is demonstrated with reference to FIG. 14. FIG.

In this Example 7, as shown in FIG. 14 , the small beam 22 is disposed lower than the main beam 21 . That is, the small beam 22 is disposed at a position lower than the upper surface of the girder 21 by a dimension corresponding to the thickness of the ALC plate 34 . In addition, the ALC board 34 is erected on the upper surfaces of the parallel two small beams 22 that join the large beams 21 to each other. Accordingly, the upper surfaces of the plurality of ALC panels 34 and the upper surface of the girder 21 are formed on the same plane.

In addition, the structural composite panel 32 is fixed to the girder 21 and the ALC panel 34 using small screws 85 and adhesive. As shown in FIG. 14 , one ALC panel 34 restrains displacement in the horizontal direction by the structural composite panel 32 fixed to the upper surface of the girder 21 and the other ALC panel 34 . In this case, since the structural composite panel 32 is fixed to both the upper surface of the girder 21 and the other ALC panel 34, compared with the case where only the structural composite panel 32 is fixed to the girder 21, it is possible to obtain Stronger binding strength and therefore preferred.

In addition, since the ALC panels 34 disposed on both sides of the girder 21 via the girder 21 can be combined with one structural composite panel 32, a wider range of ALC panels 34 can be integrated, and rotation of the ALC panels 34 can be suppressed. And can improve endurance and rigidity.

In addition, the structural composite panel 32 is arranged in a direction perpendicular to the ALC panel 34 . Therefore, the structural composite panel 32 is fixed across the plurality of ALC panels 34 . That is, since the structural composite panel 32 is fixed across the joint of the ALC panels 34, the displacement of the ALC panels 34 on both sides of the joint in the joint direction can be restrained, and the resistance and rigidity against in-plane shear force can be improved. .

Example 8

Next, a floor structure of a wooden building according to Embodiment 8 will be described with reference to FIG. 15 .

In this eighth embodiment, in order to improve the appearance of the living room space of the wooden building 1, a floor structure in which small beams 22 are positively exposed on the ceiling of the living room on the lower floor will be described.

As shown in FIG. 15 , a ceiling member 41 is laid on the top surface of the beam 22 to form the top surface of the living room 11 on the lower floor. The ceiling member 41 is formed by laying a floor covering material on a structural composite board having a thickness of, for example, 12 mm.

Joists 24 are arranged at appropriate intervals on the upper surface of the ceiling member 41 . In addition, the upper surface of the small beam 22 is lower than the upper surface of the main girder 21 by the overall dimension of the thickness of the ceiling member 41 and the height of the joist 24, and is bridged over the girder 21.

On the upper surface of the joists 24, the structural composite board 32 and the floor surface material 39 which are the floor material of the upper living room 12 are arrange|positioned. Furthermore, in order to improve the sound insulation between the upper and lower living rooms, the sound absorbing material 43 is filled between the adjacent joists 24 . For example, glass fiber with a thickness of 50 mm can be used as the sound absorbing member 43 .

Moreover, the storage part 45, such as the electric wire 49, is provided in the space formed between the joists 24. As shown in FIG. The accommodating part 45 is formed by arranging a space|interval between some joists 24 so that it may reduce. A wiring hole for leading out electric wires 49 and the like to the top surface is provided in the ceiling member 41 at the lower portion of the housing portion 45 .

A cover plate 47 having an L-shaped cross section is provided on the lower portion of the floor structure surface so as to cover the side portion of the girder 21 . In addition, the electric wires 49 are introduced into the storage portion 45 from outside the living room through the holes for wiring provided in the girder 21, and then the electric wires 49 are led out through appropriate wiring holes.

With this kind of floor structure, the ceiling of the living room 11 on the lower floor forms the top surfaces of the upper and lower floors in a concave ceiling style (Japanese: folding up the patio style), so that the height of a part of the ceiling can be set higher. On the top surface, a plurality of small beams 22 whose sides are all exposed extend in the same direction. Therefore, a feeling of wood and a sense of spaciousness can be expressed, and the appearance of the living room 11 on the lower floor can be improved. In addition, on the upper surface of the girder 22, a board body is arranged, and the board body is an integrated member of the ceiling member 41, the floor underlayment material (composite board for structure 32) and the floor covering material 39 via the joists 24. By arranging this panel on the upper surface of the girder 22, the same floor structure as that of the above-mentioned embodiment can be realized.

Example 9

Next, the floor structure of the wooden building of Example 9 is demonstrated with reference to FIG. 16A and FIG. 16B.

In each of the above-mentioned embodiments, an example of using a wooden square bar with a rectangular cross section as the small beam 22 is described, but the structure of the small beam 22 is not limited thereto, and an I-beam made of a wooden material may also be used.

16A and 16B, the I-beam 23 includes a pair of wooden I-beam flanges 231, 232 facing up and down and a wooden I-beam web 233 connecting the wooden I-beam flanges 231, 232. The wooden I-beam flanges 231 , 232 and the wooden I-beam web 233 are pressed and bonded to form an I-shaped cross section to form the I-beam 23 . The I-beam 23 can use LVL (laminated veneer lumber, laminated veneer lumber) or MSR wood (machine stress rated lumber, mechanical stress graded wood) and other structural timbers as the materials for the upper and lower wooden I-beam flanges 231, 232, Laminate floor materials such as structural composite panels or OSB (Oriented Strand Board, oriented strand board) are used as the material of the wooden I-beam web 233 . Since the I-shaped beam 23 is an I-shaped cross-section, it is lighter than the beam material with a rectangular cross-section, and the secondary moment of the cross-section is larger, so it has higher strength. Accordingly, it can be effectively used as the light and high-strength small beam 22 constituting the floor structure surface.

In this case, as shown in FIGS. 16A and 16B , both end portions of the small beam 22 are supported by the corbel metal fittings 77 attached to the side surfaces of the girder 21 . The corbel 77 includes a groove-shaped support recess 771 for supporting the side and bottom of the I-beam 23 , and mounting pieces 772 extending on both sides of the support recess 771 . The corbel 77 is fixed by nailing or the like in a state where the two mounting pieces 772 are in contact with the side surfaces of the girder 21 . The I-beam 23 is fixed by dropping both ends of the I-beam 23 into the girder metal fittings 77 installed on the side of the girder 21 at predetermined intervals. On the surface, a floor underlayment material such as a composite board 32 for a support structure, a floor surface material 39, and the like are arranged.

In addition, a ceiling member can be directly laid on the lower flange 232 of the I-beam 23 . Thereby, it becomes unnecessary to provide members, such as a hook and a ceiling bar, for supporting a ceiling member, and cost can be suppressed with a simple structure.

Example 10

Next, the floor structure of the wooden building of Example 10 is demonstrated with reference to FIG. 17. FIG.

In the wooden structure building 1, sometimes the floor covering materials of two living rooms adjacent to each other through the horizontal erection members such as the girder 21 are different from each other, so that the total thickness of the floor covering material and the floor covering material in the two living rooms A lot of difference. In this case, it is not preferable that a difference in height occurs at the joining portion of the floor coverings in the two living rooms. For this reason, in the floor structure of Embodiment 10, the load-bearing structures of the floors of two adjacent living rooms are adjusted to prevent a height difference from appearing at the junction of the floor covering materials.

As shown in FIG. 17 , living room 9A and living room 9B are adjacent to each other via door 91 . One living room 9A has floor coverings such as common floors and carpets. On the other hand, the other living room 9B is a living room where a bathroom, a toilet, etc. are exposed to water. The floor structure surface has a girder 21 between the living room 9A and the living room 9B.

On the living room 9B side, the small beam 22 parallel to the girder 21 is provided at a height position whose upper surface is lower than the upper surface of the girder 21 . A wooden support 61 is arranged parallel to the girder 21 on the side surface of the girder 21 . A hard fiberboard 36 is disposed on the upper surface of the small beam 22 and the upper surface of the support 61 . The supports 61 support the ends of the hardboard 36 . On the upper surface of the hardboard 36, tiles 95 as a floor covering material are laid on mortar 93 as an underfloor floor material.

On the other hand, in the living room 9A, the hard fiberboard 36 is arrange|positioned on the upper surface of the girder 21, and the floor surface material 39, such as a floor board, is arrange|positioned on the upper surface of this hard fiberboard 36. As shown in FIG. Thereby, at the boundary portion between the living room 9A and the living room 9B where the tiles 95 are laid, the heights of the floor surfaces of the two living rooms can be made substantially equal, and no level difference is formed. That is, on the side of the living room 9B, the living room 9B and the living room 9B are aligned by adjusting the size (the length between the upper and lower end surfaces (Japanese: 梁せい)) of the small beams 22 and the like for constituting the floor structure surface and supporting the hard fiberboard 36 and the like. The floor level of the adjacent living room 9A.
