  According to the present invention, the structure can be rationalized.

FIG. 2 is a perspective view schematically illustrating a part of the structure of a building 1. It is a perspective view explaining the joist 10 and the floor surface material 2. It is sectional drawing explaining the attachment structure of a face material. It is sectional drawing explaining the attachment structure of the face material of another form. It is sectional drawing explaining the attachment structure of a face material and a frame material. It is another figure explaining the attachment structure of a face material and a frame material.

  The present invention will be described based on embodiments shown in the drawings. However, the present invention is not limited to these modes. In the drawings shown below, some of the repeated reference numerals may be omitted for easy viewing.

  FIG. 1 is a diagram showing one embodiment, and is a perspective view extracted by paying attention to a floor 1a on the first floor and a floor 1b on the second floor in the building 1, and is shown in FIG. The parts are not shown.

  In this embodiment, as can be seen from FIG. 1, the floor surface material 2 is held and fixed from the lower surface side to a joist 10 which is one of the horizontal members. In addition, the building 1 has what a normal wooden building should have in terms of its structure, and a publicly known form can be applied to this. A horizontal wall frame 3 and a vertical wall frame 4, which are frame members for forming a wall, are provided on the outer peripheral portions of the floors 1a and 1b. In FIG. 1, the horizontal wall frame 3 and the vertical wall frame 4 are partially cut away.

  Hereinafter, in the building 1, the joist 10, the floor surface material 2 attached thereto, and the mounting structure of the surface material using the joist 10 (horizontal member 10) by these will be described. FIG. 2 is a perspective view showing a part of the mounting structure of the face material. In FIG. 2, the surface material on the lower right side of the paper is omitted to represent the joist 10. FIG. 3 is a cross-sectional view in a direction orthogonal to a direction in which the joist 10 has an H-shaped cross section and extends in the mounting structure of the face material. FIG. 3 shows one joist 10 and two floor members 2 attached thereto. As can be seen from FIGS. 1 to 3, the face member mounting structure includes a floor surface member 2, a joist 10 as a horizontal member, and a fixing member 15.

  The floor surface material 2 is a plate-shaped member for forming a floor, and a known floor surface material can be applied. When used as a building, a decorative material or the like forming the floor is arranged on the upper surface of the floor material 2 (the surface opposite to the side where the joists 10 are arranged).

  The joist 10 is one of the horizontal members, and is a rod-shaped member that supports the floor surface material. In the present invention, the joist 10 is an elongate member comprising an H-shaped steel, and therefore having an H-shaped cross section and extending in one direction, as can be seen from FIG. More specifically, as can be seen from FIG. 3, the joist 10 has a face material side flange 11, a base flange 12, and a web 13.

  The face material side flange 11 is a flange on which a face material (in this embodiment, the floor face material 2) is placed and to which the face material is fixed. The thickness of the face material side flange 11 (the size in the vertical direction of the paper surface of FIG. 3) is smaller than the thickness of the base flange 12, and the cross-sectional area of the cross section of the face material side flange 11 shown in FIG. It suffices if the cross-sectional area of the cross-section of FIG. Here, “substantially the same” does not need to be strictly the same, but means that the difference of the degree considered to be the same can be regarded as the same. Specifically, the difference up to ± 10% may be considered the same. Therefore, according to this, the width of the face material side flange 11 (the size in the left-right direction of FIG. 3) is larger than the width of the base flange 12.

As long as the above is satisfied, the specific dimensions of the face material side flange 11 are not particularly limited, but the thickness T ₁₁ of the face material side flange 11 is preferably equal to or less than half of the base flange 12. More specifically, it is more preferable that the thickness _{T 11} is 1.6mm or more 6.0mm or less. Thereby, even if the fixing member 15 is a nail or a drill screw, the fixing can be stably performed by appropriately penetrating the face material side flan 11.
The width _{W 11} is preferably at least 100mm 200mm or less. According to this, the overlapping portion between the face material side flange 11 and the face material 2 can be made large, which also makes it easy to fix the face material side flange 11 and the face material 2. Furthermore, since the deformation of the face material side flange 11 due to the joining with the floor face material 2 is restrained, local buckling becomes difficult, and the strength is improved.

  The base flange 12 is a flange which is arranged in parallel with a predetermined interval so that the face material side flange 11 and one surface face each other. As described above, the thickness of the base flange 12 is larger than the thickness of the face material side flange 11, and the cross-sectional area of the cross section of the face material side flange 11 shown in FIG. It is sufficient if they are substantially the same.

As long as the above is satisfied, the specific dimensions of the base flange 12 are not particularly limited, but the thickness of the base flange 12 is T ₁₂ , and the thickness T ₁₂ is the thickness T of the face material side flange 11. it is preferable ₁₁ is less than half of the thickness _{T 12.} More specifically, the thickness _{T 12} is more preferably 15mm or less than 3.2 mm. Thereby, sufficient bending resistance can be secured.
Further, it is preferable that the width _{W 12} is 80mm or more than 100mm.

The web 13 is a plate-like member having one end joined to the face material side flange 11 and the other end joined to the base flange 12 in the cross section shown in FIG. Thereby, the face material side flange 11 and the base side flange 12 are integrated. The means for joining is not particularly limited, and a known joining technique can be used. This can include, for example, welding.
Here, the web 13 is preferably arranged such that the joists 10 are symmetrical with respect to the cross section shown in FIG. According to this, the center of gravity in the cross section of the joist 10 shown in FIG. The position of the center of gravity is preferably a position near the center in the thickness direction of the joist 10 in the cross section in FIG. As a result, the degree of stress generated in the face material side flange 11 and the base side flange 12 with respect to the bending moment caused by the load becomes substantially the same, and either one does not yield in advance, and a reasonable design is required. Can be.

  The distance D between the face material side flange 11 and the base flange 12 maintained by the web 13 is not particularly limited, but is preferably in the range of 100 mm or more and 450 mm or less.

  Here, the joist 10 is formed of a steel material. The specific type of the steel material is not particularly limited, but it is preferable to use a material for a building structure.

  As described above, a plurality of joists 10 are horizontally arranged as shown in FIG. At this time, the face material side flange 11 is arranged so as to be on the floor face material 2 side. Then, the floor surface material 2 is placed so as to pass over the surface of the surface material side flange 11 of the plurality of joists 10, and as shown in FIG. 3, the portion where the floor surface material 2 and the surface material side flange 11 overlap with each other Then, the fixing member 15 is arranged so as to penetrate both in the thickness direction. Here, the fixing member 15 is not particularly limited in its aspect as long as it can join a portion where the floor surface material 2 and the surface material side flange 11 overlap, but for example, a nail or a drill screw can be used. As a result, a structure for mounting the surface material using the horizontal member by the joist 10 and the floor surface material 2 is formed.

  According to this structure, since the H-shaped steel is used as the horizontal member, high durability against wood can be ensured. In addition, since the cross-sectional shape of the horizontal member is formed as described above, the face member can be directly joined to the horizontal member made of H-shaped steel, and the number of parts and the number of processing steps can be reduced. Further, while the shapes of the face material side flange 11 and the base flange 12 were made different depending on the purpose, the cross-sectional areas of both were made substantially the same. Thereby, the neutral axis can substantially maintain the center of the horizontal member, and the bending rigidity and the proof stress can be kept to the maximum. Accordingly, it is not necessary to change the strength design or the like irrespective of the cross-sectional shape, and the design is facilitated.

FIG. 4 is a view for explaining another embodiment, and is a view from the same viewpoint as FIG. Also in this embodiment, in the building 1, the joist 20, the floor material 2 attached thereto, and the mounting structure of the surface material using the joist 20 (horizontal member 20) by these will be described.
In the present embodiment, the joist 20 is applied instead of the joist 10 described above, and the other portions are common to the description so far, so the joist 20 will be described, and the description of the other portions will be omitted.

The joist 20 is also one of the horizontal members, and is a rod-shaped member that supports the floor surface material. Also in this embodiment, the joist 20 is an elongated member having an H-shaped steel, and thus having an H-shaped cross section and extending in one direction, as can be seen from FIG. More specifically, the joist 20 has a face material side flange 21, a base flange 12, and a web 13.
Since the base flange 12 and the web 13 are common to the joist 10, the description is omitted here.

The face material side flange 21 is also a flange on which the face material (the floor face material 2 in this embodiment) is placed and the face material is fixed. The face material side flange 21 has a form in which both ends in the width direction of the face material side flange 11 are bent, and more specifically, is configured to have a main portion 21a and a bent portion 21b.
The main portion 21a is a portion of the face material side flange 21 that is arranged in parallel with a predetermined interval so that the base flange 11 and one surface face each other. The thickness (the size in the vertical direction of the drawing in FIG. 4) of the main portion 21 a of the face material side flange 21 is smaller than the thickness of the base flange 12. The thickness of the main portion 21a but are not limited to satisfy this, it is preferable that the thickness T ₂₁ of the main portion 21a is less than half of the base flange 12. More specifically, it is more preferable that the thickness _{T 21} is 1.6mm or more 6.0mm or less. Thereby, even if the fixing member 15 is a nail or a drill screw, it is possible to properly penetrate through the main part 21a and stably fix it. That is, when a compressive force is applied to the face material side flange 21 by a load from above, local buckling becomes difficult due to the form in which both ends in the width direction of the face material side flange 21 are bent. Since the deformation of the member 21 with the floor member 2 is restricted, the local buckling becomes difficult, and the proof stress is improved.

  The bent portion 21b is a portion formed such that both ends in the width direction of the main portion 21a are bent and the direction is changed with respect to the main portion 21a. Thereby, the strength of the main portion 21a formed thin can be improved. In the present embodiment, the bent portion 21b is formed so as to be turned 90 degrees in the width direction of the main portion 21a with respect to the direction in which the main portion 21a extends toward the base flange 12. However, the angle need not be 90 degrees, but may be greater than 0 degrees and equal to or less than 180 degrees.

  Then, the cross-sectional area of the cross section of the face material side flange 21 including the main portion 21a and the bent portion 21b shown in FIG. Here, “substantially the same” is the same as that described for the face material side flange 11.

Further, it is preferable that the width _{W 21} of the face plate flange 21 is 100mm or more 200mm or less. According to this, the overlapping portion between the face material side flange 21 and the face material 2 can be made large, which also makes it easy to fix the face material side flange 11 and the face material 2.

  Here, the distance D between the main portion 21a of the face material side flange 21 maintained by the web 13 and the base flange 12 is not particularly limited, but is preferably in the range of 100 mm or more and 450 mm or less.

FIG. 5 and FIG. 6 are diagrams for explaining a mounting structure of a face member and a frame member to which the joists 20 (horizontal members) are applied. FIG. 5 is a view from the same viewpoint as FIGS. 3 and 4, and FIG. 6 is a view from the direction indicated by the arrow VI in FIG.
In this embodiment, in addition to the above-described mounting structure using the joists 20 and the floor surface material 2, the horizontal frame member 3 and the vertical frame member 4 also have a mounting structure added thereto. Therefore, in this mounting structure, in addition to the joist 20, the floor surface material 2, the fixing member 15, the horizontal frame member 3, and the vertical frame member 4, a connecting member 30 and a fixing member 31 are provided. Here, the joist 20, the floor member 2, and the fixing member 15 are common to those described above, and thus description thereof is omitted.

  The horizontal frame member 3 is a bar-shaped elongate member that is placed on the surface of the floor panel 2 opposite to the side on which the joists 20 are arranged, and extends along the surface. It functions as a wall frame material combined with 4. As such a horizontal frame material 3 itself, a known material can be used, and there is no particular limitation.

  The vertical frame member 4 is a bar-shaped elongate member that is erected from the surface of the horizontal frame member 3 opposite to the floor surface member 2 and is arranged to extend in the vertical direction. It functions as a frame material of the wall combined with 3. As such a vertical frame material 4 itself, a known material can be used, and there is no particular limitation.

  The connecting member 30 is a rectangular plate-like member, and is provided with a bent portion 30a which is bent so that one side of the square is standing on the plate surface as can be seen from FIG. The shape to be provided by the connecting member 30 will be clarified in the description of the combination with other members. In this embodiment, two connecting members 30 are provided.

  The fixing member 31 is a member for fixing the connecting member 30 to the horizontal frame member 3 and the vertical frame member 4, and the form is not particularly limited as long as such fixing can be performed. And drill screws.

  Here, the connecting members 30 are combined as follows. That is, as can be seen from FIGS. 5 and 6, the joist 20 penetrates an opening (not shown) provided in the face material 2 in advance, and the joists 20 are arranged in the width direction from the horizontal material 20, the face material 2, and the horizontal frame material 3. And the connecting member 30 is arranged so as to surround at least a part of the vertical frame member 4. At this time, the connecting member 30 is arranged such that the protruding corner of the outer surface 12a at the widthwise end of the base flange 12 is hooked on the entering corner formed by the bent portion 30a of the connecting member 30. Thereby, the positional relationship between the joist 20 and the connecting member 30 can be stably maintained.

  With this arrangement, the joist 20, the horizontal frame member 3, and the vertical frame member 4 are arranged between the two connecting members 30. Then, the fixing member 31 is disposed so as to penetrate the connecting member 30 from both sides in the width direction with respect to the horizontal frame member 3 and the vertical frame member 4, and the connecting member 30 and the horizontal frame member 3 and the vertical frame member 4 are connected to each other. Is fixed. As a result, the joist 20, the floor member 2, the horizontal frame member 3, and the vertical frame member 4 are integrated, and a simple form in which the frame members are integrated in addition to the above-described configuration can be obtained.

  Although the example of the joist has been described as the horizontal member, the invention is not limited thereto, and the horizontal member can be applied to a beam, a girder, or the like.
