Description
本発明は、建物の床構造に関する。 The present invention relates to a floor structure of a building.
木造軸組工法における在来工法では、構造部材である柱、梁、桁等の２つ以上の部材を組み合わせて接合する場合には、ほぞ（突起部分）と、ほぞ穴とのようなものを作り、組み合わせていた。しかし、複数の接合する部材が特定の箇所に集中すると、ほぞ穴等により断面積が減少するため、耐震性や強度を考慮して、近年では、そのような接合箇所に特殊な金物（金具）を用いる金物工法(金具工法又はメタルジョイント工法）が用いられている（例えば特許文献１）。床構造では、床梁と柱との接合箇所や、床梁を他の床梁に固定する接合箇所は、特殊な金物（例えば梁受け金物等）により接合されている。また、複数の床梁間に等間隔で渡される床根太の端部も、特殊な金物（いわゆる根太受け金物）により床梁等に保持されている。 In the conventional construction method in the wooden frame construction method, when two or more members such as pillars, beams, girders, etc., which are structural members are combined and joined, a tenon (projection part) and a mortise hole are used. Made and combined. However, when multiple members to be joined are concentrated at a specific location, the cross-sectional area decreases due to mortises, etc. In recent years, special hardware (metal fittings) is used at such locations in consideration of earthquake resistance and strength. A hardware method (metal fitting method or metal joint method) is used (for example, Patent Document 1). In the floor structure, the joint between the floor beam and the column and the joint where the floor beam is fixed to another floor beam are joined by a special hardware (for example, a beam receiving metal). In addition, the ends of the floor joists passed at equal intervals between the plurality of floor beams are also held on the floor beams and the like by special hardware (so-called joist support hardware).
具体的には、図２に示すように、従来の木造軸組工法における床構造11では、複数の床梁40は、建物10の基準寸法（以下、「モジュール」とする。）の整数倍の間隔で配置されている。モジュールとは、建築のあらゆる部分を一定の大きさの倍数関係に整える際の基準となる寸法である。このモジュールは、特に限定されるものではないが、例えば９１０ｍｍ（尺モジュール）、１０００ｍｍ（メーターモジュール）、１２１８ｍｍ（インチモジュール）等がある。仮に、基本となる１モジュールを９１０ｍｍとすると、１モジュールの１／２（ハーフモジュール）は４５５ｍｍ、１モジュールの１／４（クォーターモジュール）は２２７．５ｍｍとなる。 Specifically, as shown in FIG. 2, in the floor structure 11 in the conventional wooden frame construction method, the plurality of floor beams 40 is an integral multiple of a reference dimension (hereinafter referred to as “module”) of the building 10. Arranged at intervals. A module is a standard dimension for arranging all parts of a building in a multiple of a certain size. Although this module is not specifically limited, For example, there exist 910 mm (scale module), 1000 mm (meter module), 1218 mm (inch module) etc. If one basic module is 910 mm, 1/2 (half module) of 1 module is 455 mm, and 1/4 (quarter module) of 1 module is 227.5 mm.
特定の基準寸法のモジュールを符号Ｍとすると、この建物10の床構造11では、全体として長方形状の領域の長辺側の長さが１０Ｍ（１モジュールの１０倍）、短辺側の長さが７Ｍ（１モジュールの７倍）に設定されている。
この建物10の床構造11において、複数の床梁40の間に１／２Ｍ（１モジュールの１／２）の間隔で床根太60が配置されている。すなわち、床根太60は、長方形状の床構造11の長辺の床梁40と平行に配置されており、隣接する２つの床根太60間の距離が、１／２Ｍ（１モジュールの１／２）に設定されている。
Assuming that a module having a specific reference dimension is M, in the floor structure 11 of the building 10, the length of the long side of the rectangular area as a whole is 10M (10 times that of one module) and the length of the short side. Is set to 7M (7 times one module).
In the floor structure 11 of the building 10, floor joists 60 are arranged between the plurality of floor beams 40 at intervals of 1 / 2M (1/2 of one module). That is, the floor joists 60 are arranged in parallel with the long-side floor beam 40 of the rectangular floor structure 11, and the distance between two adjacent floor joists 60 is 1 / 2M (1/2 of one module). ) Is set.
また、床根太60に平行な床梁40と、この床梁40に隣接する床根太60との距離も、同様に１／２Ｍ（１モジュールの１／２）に設定されている。
具体的には、床根太60は、この床根太60に隣接する床梁40から０．５Ｍの位置に設けられ、床根太60同士は０．５Ｍの間隔で配置されており、その先の床根太60は、前記床梁40からの距離が１．０Ｍ、１．５Ｍ、２．０Ｍ、２．５Ｍ、３．０Ｍ・・・となるような位置に配置されている。
Similarly, the distance between the floor beam 40 parallel to the floor joist 60 and the floor joist 60 adjacent to the floor beam 40 is also set to 1 / 2M (1/2 of one module).
Specifically, the floor joists 60 are provided at a position of 0.5M from the floor beam 40 adjacent to the floor joists 60, and the floor joists 60 are arranged at an interval of 0.5M, and the floor ahead of them. The joists 60 are arranged at positions such that the distance from the floor beam 40 is 1.0M, 1.5M, 2.0M, 2.5M, 3.0M.
図２に示すように、上述したように床根太60が配置されると、床梁40がモジュールの整数倍の位置（上述した例では、例えば１．０Ｍ、２．０Ｍ、３．０Ｍ、・・のいずれかの位置）に配置されているため、床根太60の端部を床梁40に固定するための特殊金物50（根太受け金物51）と、床梁40を柱20や他の床梁40に固定するための特殊金物50（梁受け金物52）との取付位置が同一位置になる場合が発生する。
これらの特殊金物50の形状や寸法によっては、特殊金物50（根太受け金物51及び梁受け金物52）同士が干渉して取り付けが困難になるため、特殊金物50（根太受け金物51及び梁受け金物52）の形状や寸法を調整しなければならず、設計上、手間であるという問題点があった。
As shown in FIG. 2, when the floor joists 60 are arranged as described above, the floor beam 40 is positioned at an integral multiple of the module (in the above example, for example, 1.0M, 2.0M, 3.0M,.・ A special hardware 50 for fixing the end of the floor joist 60 to the floor beam 40 (the joist receiving metal 51) and the floor beam 40 for the column 20 or other floor. In some cases, the mounting position of the special hardware 50 (beam receiving hardware 52) for fixing to the beam 40 is the same.
Depending on the shape and dimensions of these special hardware 50, the special hardware 50 (the joist receiving metal 51 and the beam receiving metal 52) interferes with each other, and it becomes difficult to mount the special hardware 50 (the joist receiving metal 51 and the beam receiving metal). 52) The shape and dimensions had to be adjusted, and there was a problem that it was troublesome in design.
また、特定箇所に複数の特殊金物50（根太受け金物51及び梁受け金物52）や、床根太60や、床梁40や、柱20等が集中すると、現場での取り付け作業における作業スペースが減少し、取り付け作業をスムーズに進めることが難しくなって現場作業がやりにくいという問題点があった。
また、上述したような特殊金物50（根太受け金物51）を用いずに、床梁40の部材を現場へ移送する前、加工工場におけるプレカットで切り欠き溝を設けて、この切り欠き溝に床根太60の端部を落とし込んで床梁40に固定する床根太60の落とし込み工法がある。この工法では現場において特殊金物50（根太受け金物51）を取り付ける手間が不要となり、現場施工期間の工期短縮が可能となるものである。しかし、床梁40を柱20や他の床梁40に固定するための特殊金物50（梁受け金物52）が取り付けられている箇所では、床梁40の断面積が小さくなる等の理由のため、切り欠き溝を設けるような床根太60の落とし込み工法を採用することが難しいという問題点があった。
In addition, when multiple special hardware 50 (beam joist 51 and beam 52), floor joists 60, floor joists 40, pillars 20, etc. are concentrated at a specific location, the work space for installation work at the site is reduced. However, there is a problem that it is difficult to carry out the installation work smoothly and the field work is difficult to do.
In addition, without using the special hardware 50 (the joist bracket 51) as described above, a notch groove is provided in the notch groove by pre-cutting at a processing plant before the member of the floor beam 40 is transferred to the site. There is a method for dropping the floor joists 60, in which the ends of the joists 60 are dropped and fixed to the floor beam 40. This construction method eliminates the need for attaching the special hardware 50 (the joists 51) and shortens the construction period. However, at the place where the special hardware 50 (beam receiving hardware 52) for fixing the floor beam 40 to the column 20 or other floor beam 40 is attached, the cross-sectional area of the floor beam 40 becomes small. However, there is a problem that it is difficult to adopt a floor joist 60 dropping method in which a notch groove is provided.
また、これらの特殊金物50（根太受け金物51及び梁受け金物52）は、釘やネジ等の締結部材で床梁40等に固定するため、特殊金物50（根太受け金物51及び梁受け金物52）同士が特定の箇所に集中すると、その箇所において釘やネジ等の締結部材が内部に多数、打ち込まれ、またねじ込まれることで割れが発生したり、当該箇所の強度が低下してしまう可能性があるという問題点があった。
請求項１及び２に記載の発明は、上記した従来の技術の有する問題点に鑑みてなされたものであり、その目的とするところは、床梁及び床根太の取付位置が同一箇所となって互いに干渉しあうようなことが発生せず、設計を容易にし、現場での取付作業において作業スペースを確保できて現場作業を容易にして工期短縮が可能となり、均質で十分な強度を確保し維持することが可能な床構造を提供することができる。
In addition, these special hardware 50 (the joist receiving metal 51 and the beam receiving metal 52) are fixed to the floor beam 40 or the like with a fastening member such as a nail or a screw. ) If they are concentrated at a specific location, a large number of fastening members such as nails and screws may be driven into the location, and cracking may occur or the strength of the location may be reduced. There was a problem that there was.
The inventions described in claims 1 and 2 have been made in view of the above-described problems of the prior art, and the purpose thereof is that the mounting positions of the floor beam and the floor joist are the same location. Interfering with each other does not occur, design is facilitated, work space can be secured in field installation work, field work can be facilitated and work period can be shortened, and uniform and sufficient strength can be secured and maintained. A floor structure that can be provided can be provided.

As a result, the attachment positions do not interfere with each other at the same location. For this reason, it is not necessary to adjust in advance the dimensions and shape of the hardware in the design stage so as not to interfere with each other, and the design stage can be facilitated.
また、床根太60の端部を取り付ける位置と、床梁40を柱20や他の床梁40に取り付ける位置とが離れることで現場での取り付け作業において、作業スペースを十分余裕を持って確保することができる。これにより、現場における取付作業をスムーズに進めることができ現場作業を容易なものにすることができる。
また、床根太60の端部の取付位置と、床梁40を柱20や他の床梁40に固定するための特殊金物50の取付位置とが同一箇所に集中せずに離れて互いに干渉しないため、床梁40に切り欠き溝を設けて、この切り欠き溝に床根太60の端部を落とし込んで固定可能な床根太60の落とし込み工法を採用することができる。これにより、現場施工において床根太60の端部を床梁40に固定するための金物（いわゆる根太受け金物51）を用いる必要がなく、経済的で現場施工の工期短縮が可能となる。
In addition, the installation position on the site is secured with sufficient margin by separating the position where the end of the floor joist 60 is attached and the position where the floor beam 40 is attached to the column 20 or other floor beam 40. be able to. Thereby, the installation work in a field can be advanced smoothly and a field work can be made easy.
Also, the mounting position of the end of the floor joist 60 and the mounting position of the special hardware 50 for fixing the floor beam 40 to the column 20 or other floor beam 40 do not concentrate on the same place and do not interfere with each other. Therefore, it is possible to use a floor joist 60 dropping method that can be provided with a notch groove in the floor beam 40 and the end of the floor joist 60 can be dropped into the notch groove and fixed. Thereby, it is not necessary to use a hardware for fixing the end portion of the floor joist 60 to the floor beam 40 in the on-site construction (so-called joist support 51), and it is economical and the construction period of the on-site construction can be shortened.
また、上述したように床根太60の端部の取付位置と、床梁40の取付位置とが同一箇所に集中せずに分散されることで、釘やネジ等の締結部材が床梁40の特定の箇所に集中することが無く、床梁40の均質で安定した強度を確保し維持することができる。
（請求項２）
請求項２記載の発明は、前記床根太60に平行な前記床梁40と、この床梁40に隣接する前記床根太60との距離は、前記モジュールの１／４にしたことを特徴とする。
本発明では、床根太60に平行な床梁40と、この床梁40に隣接する床根太60との距離は、１モジュールの１／４（０．２５Ｍ）に設定されている。複数の床根太60は、モジュールの１／２（０．５Ｍ）の間隔で配置されている。すなわち、床根太60同士は、０．５Ｍの間隔で配置されているため、その先は、前記床梁40からの距離が、０．７５Ｍ、１．２５Ｍ、１．７５Ｍ、２．２５Ｍ、２．７５Ｍ・・・となるような位置に床根太60が配置されている。
Further, as described above, the mounting position of the end of the floor joist 60 and the mounting position of the floor beam 40 are dispersed without being concentrated in the same place, so that fastening members such as nails and screws can be attached to the floor beam 40. It is possible to ensure and maintain the uniform and stable strength of the floor beam 40 without concentrating on a specific location.
(Claim 2)
The invention according to claim 2 is characterized in that a distance between the floor beam 40 parallel to the floor joist 60 and the floor joist 60 adjacent to the floor joist 40 is ¼ of the module. .
In the present invention, the distance between the floor beam 40 parallel to the floor joist 60 and the floor joist 60 adjacent to the floor joist 40 is set to 1/4 (0.25 M) of one module. The plurality of floor joists 60 are arranged at intervals of 1/2 (0.5 M) of the module. That is, since the floor joists 60 are arranged at intervals of 0.5M, the distance from the floor beam 40 is 0.75M, 1.25M, 1.75M, 2.25M, 2 . Floor joists 60 are arranged at positions such that .75M.
一方、複数の床梁40は、モジュールの整数倍の間隔で配置されている。このため、複数の床梁40の位置は、床梁40からの距離が例えば１．０Ｍ、２．０Ｍ、３．０Ｍ、・・・・から選択される位置になる。
結果として、床根太60が配置される位置は、床梁40が配置される位置から必ず０．２５Ｍ（１モジュールの１／４）だけずれていることになる。

On the other hand, the plurality of floor beams 40 are arranged at intervals of an integral multiple of the module. Therefore, the positions of the plurality of floor beams 40 are positions where the distance from the floor beam 40 is selected from, for example, 1.0M, 2.0M, 3.0M,.
As a result, the position where the floor joists 60 are arranged is always shifted from the position where the floor beam 40 is arranged by 0.25 M (1/4 of one module).
As a result, the mounting position for fixing the end of the floor joist 60 to the floor beam 40 and the mounting position for fixing the floor beam 40 to the column 20 or another floor beam 40 are always 0.25M (one module). Therefore, the attachment positions are not located in the same place and do not interfere with each other. For this reason, it is not necessary to adjust in advance the dimensions and shape of the hardware in the design stage so as not to interfere with each other, and the design stage can be facilitated.
本発明は、以上のように構成されているので、以下に記載されるような効果を奏する。
請求項１及び２に記載の発明によれば、床梁及び床根太の取付位置が同一箇所となって互いに干渉しあうようなことが発生せず、設計段階での調整が不要で設計を容易にすることができ、さらに、現場での取付作業において作業スペースを確保できて現場作業を容易にして工期短縮が可能で、さらに、床梁の均質で十分な強度を確保し維持することができるようにした床構造を提供することができる。

（作用及び効果）
本実施の形態では、上述したように、床根太60に平行な床梁40と、この床梁40に隣接する床根太60との距離は、１／４Ｍ（０．２５Ｍ、１モジュールの１／４）に設定され、複数の床根太60は、モジュールの１／２の間隔で配置されているため、その先は、該床梁40からの距離が、０．７５Ｍ、１．２５Ｍ、１．７５Ｍ、２．２５Ｍ、２．７５Ｍ・・・６．２５Ｍ、６．７５Ｍとなるような位置に床根太60が配置されている。
That is, the floor joists 60 adjacent to the floor beams 40 are provided at a position of 0.25M from the floor beams 40, and the floor joists 60 are arranged at an interval of 0.5M. Floor joists 60 are arranged at equal intervals at positions such that the distance from 40 is 0.75M, 1.25M, 1.75M, 2.25M, 2.75M ... 6.25M, 6.75M. Yes.
(Function and effect)
In the present embodiment, as described above, the distance between the floor beam 40 parallel to the floor joist 60 and the floor joist 60 adjacent to the floor joist 40 is 1 / 4M (0.25M, 1 / one module). 4), and the plurality of floor joists 60 are arranged at ½ intervals of the module, so that the distance from the floor beam 40 is 0.75M, 1.25M, 1.. Floor joists 60 are arranged at positions such as 75M, 2.25M, 2.75M, 6.25M, and 6.75M.
一方、複数の床梁40は、モジュールの整数倍の間隔で配置されている。床根太60に平行な複数の床梁40の位置は、建物10の外壁の位置の床梁40からの距離が例えば１．０Ｍ、２．０Ｍ、３．０Ｍ、・・・・から選択される位置になる。
すなわち、床根太60が配置される位置は、この床根太60と平行であって、この床根太60に隣接する床梁40が配置される位置から必ず０．２５Ｍ（１モジュールの１／４）だけずれていることになる。
これにより、床根太60の端部を床梁40に固定するための取付位置と、床梁40を柱20や他の床梁40に固定するための特殊金物50の取付位置とが必ず０．２５Ｍ（１モジュールの１／４）だけずれていることになり、これらの取付位置同士が同一箇所になって互いに干渉しあうようなことが発生しない。このため、互いに干渉しないように特殊金物50の寸法や形状等を設計段階で予め調整する必要がなく、設計段階を容易なものにすることができる。
On the other hand, the plurality of floor beams 40 are arranged at intervals of an integral multiple of the module. The positions of the plurality of floor beams 40 parallel to the floor joists 60 are selected from, for example, 1.0M, 2.0M, 3.0M,... Become position.
That is, the position where the floor joists 60 are arranged is parallel to the floor joists 60, and is always 0.25M (1/4 of one module) from the position where the floor beams 40 adjacent to the floor joists 60 are arranged. It will be shifted only.
Accordingly, the mounting position for fixing the end of the floor joist 60 to the floor beam 40 and the mounting position of the special hardware 50 for fixing the floor beam 40 to the column 20 or another floor beam 40 are always 0. It is shifted by 25M (1/4 of one module), and these attachment positions are not located in the same place and interfere with each other. For this reason, it is not necessary to adjust the dimensions and shape of the special hardware 50 in advance at the design stage so as not to interfere with each other, and the design stage can be facilitated.
また、床根太60は、上述したように、１モジュールの整数倍の位置から、０．２５Ｍだけずれて配置されているため、その１モジュールの整数倍の位置に特殊金物50を用いて後から補強用の床梁40を追加して設けるようなことが可能となる。これにより、設計や施工の自由度を増すことができ、柔軟な対応が可能となる。
また、床根太60の端部を取り付ける位置と、床梁40を柱20や他の床梁40に取り付ける位置とが離れることで、現場での取り付け作業において、作業スペースを十分余裕を持って確保することができる。これにより、現場における取付作業をスムーズに進めることができ現場作業を容易なものにすることができる。
Further, as described above, the floor joist 60 is arranged by being shifted by 0.25 M from a position that is an integral multiple of one module, so that a special hardware 50 is used later at a position that is an integral multiple of one module. It is possible to additionally provide a floor beam 40 for reinforcement. Thereby, the freedom degree of design and construction can be increased, and a flexible response | compatibility is attained.
In addition, the installation position of the floor joist 60 is separated from the position where the floor beam 40 is attached to the pillar 20 or another floor beam 40, so that a sufficient work space is secured in the field installation work. can do. Thereby, the installation work in a field can be advanced smoothly and a field work can be made easy.
また、床根太60の端部の取付位置と、床梁40を柱20や他の床梁40に固定するための特殊金物50の取付位置とが離れて互いに干渉しないため、床梁40に切り欠き溝を設けて、この切り欠き溝に床根太60の端部を落とし込んで固定可能な床根太60の落とし込み工法を採用することができる。これにより、現場施工において床根太60の端部を床梁40に固定するための根太受け金物51（図２参照）等を用いる必要がなく、経済的で現場施工の工期短縮が可能となる。
また、上述したように複数の取付位置が同一箇所に集中せずに分散されることで、釘やネジ等の締結部材が床梁40の特定の箇所に集中することが無く、床梁40の均質で安定した強度を確保し維持することができる。
In addition, the mounting position of the end of the floor joist 60 and the mounting position of the special hardware 50 for fixing the floor beam 40 to the column 20 and other floor beams 40 are separated and do not interfere with each other. It is possible to adopt a floor joist 60 dropping method that can be provided with a notch groove and the end of the floor joist 60 can be dropped into the notch groove and fixed. Thereby, it is not necessary to use the joist support 51 (see FIG. 2) for fixing the end of the floor joist 60 to the floor beam 40 in the field construction, and it is economical and the construction period of the field construction can be shortened.
Further, as described above, a plurality of mounting positions are dispersed without concentrating on the same location, so that fastening members such as nails and screws do not concentrate on a specific location on the floor beam 40, and the floor beam 40 A uniform and stable strength can be secured and maintained.
なお、本実施の形態では、床根太60に平行な床梁40と、この床梁40に隣接する床根太60との距離は、１／４Ｍ（１モジュールの１／４）に設定されているが、特にこの数値に限定されるものではなく、床梁40と床根太60とが干渉しないように所定の距離だけ離れて配置されてあれば良いものである。 In the present embodiment, the distance between the floor beam 40 parallel to the floor joist 60 and the floor joist 60 adjacent to the floor joist 40 is set to 1/4 M (1/4 of one module). However, it is not particularly limited to this value, and it is only necessary that the floor beam 40 and the floor joist 60 be arranged at a predetermined distance so as not to interfere with each other.
