(第１実施形態)
図１を参照して、建築物本体１００が設置された建築物の基礎構造１０について説明する。基礎構造１０および建築物本体１００は建築物２００を構成する。基礎構造１０はグランドレベルＧＬを鉛直方向に跨ぐように地盤Ｇに設置される。なお、図２〜図４では、図面の簡略化のため、建築物本体１００の図示を省略している。
(First embodiment)
With reference to FIG. 1, the foundation structure 10 of the building in which the building main body 100 was installed is demonstrated. The foundation structure 10 and the building main body 100 constitute a building 200. The foundation structure 10 is installed on the ground G so as to straddle the ground level GL in the vertical direction. 2 to 4, the building main body 100 is not shown for simplification of the drawings.
建築物本体１００は例えば店舗、個別住宅、または、集合住宅である。店舗は例えば、ローサイド店舗である。ローサイド店舗は例えばコンビニエンスストアである。建築物本体１００は躯体１１０および外壁１２０を備える。基礎構造１０を構成する主な要素はコンクリート製基礎２０、鋼製基礎梁３０、複数の支持鋼材７０、および、ダウン基礎梁９０(図４参照)である。コンクリート製基礎２０と鋼製基礎梁３０とは複数の支持鋼材７０およびダウン基礎梁９０により結合される。躯体１１０はボルト１３０により鋼製基礎梁３０に結合される。外壁１２０は躯体１１０を覆う。 The building body 100 is, for example, a store, an individual house, or an apartment house. The store is, for example, a low-side store. The low side store is, for example, a convenience store. The building body 100 includes a housing 110 and an outer wall 120. Main elements constituting the foundation structure 10 are a concrete foundation 20, a steel foundation beam 30, a plurality of supporting steel members 70, and a down foundation beam 90 (see FIG. 4). The concrete foundation 20 and the steel foundation beam 30 are coupled by a plurality of supporting steel members 70 and a down foundation beam 90. The frame 110 is coupled to the steel foundation beam 30 by bolts 130. The outer wall 120 covers the housing 110.
コンクリート製基礎２０を構成する材料は強アルカリ性のコンクリートである。コンクリート製基礎２０は補助層１１上に形成される。コンクリート製基礎２０の上部２１はグランドレベルＧＬよりも上方に位置する。補助層１１はコンクリート製基礎２０の製造を補助するために必要に応じて形成される。補助層１１の構造は例えば砕石層、または、砕石層および捨てコンクリート層である。砕石層の上面１１Ａは転圧によって面一となるように形成される。鋼製基礎梁３０は支持鋼材７０と結合される。 The material constituting the concrete foundation 20 is strongly alkaline concrete. The concrete foundation 20 is formed on the auxiliary layer 11. The upper part 21 of the concrete foundation 20 is located above the ground level GL. The auxiliary layer 11 is formed as necessary to assist the manufacture of the concrete foundation 20. The structure of the auxiliary layer 11 is, for example, a crushed stone layer, or a crushed stone layer and a discarded concrete layer. The upper surface 11A of the crushed stone layer is formed to be flush with the rolling force. The steel foundation beam 30 is coupled to the support steel material 70.
鋼製基礎梁３０および支持鋼材７０の外周には、パネル状の化粧型枠８０が設置される。化粧型枠８０は建築物本体１００の外壁１２０とともに建築物本体１００の外観を構成する。このため、基礎構造１０を含む建築物２００の美観が高められる。また、化粧型枠８０はコンクリート製基礎２０を形成するときの型枠として機能する。化粧型枠８０を構成する材料は任意に選択できる。その一例は窯業系パネルである。窯業系パネルは例えばサイディングパネルである。化粧型枠８０は下部８１がグランドレベルＧＬよりも下方に位置するように設けられる。 A panel-shaped decorative mold 80 is installed on the outer periphery of the steel foundation beam 30 and the supporting steel material 70. The decorative mold 80 constitutes the exterior of the building body 100 together with the outer wall 120 of the building body 100. For this reason, the beauty of the building 200 including the foundation structure 10 is enhanced. The decorative mold 80 functions as a mold when forming the concrete foundation 20. The material constituting the decorative mold 80 can be arbitrarily selected. One example is a ceramic panel. The ceramic panel is a siding panel, for example. The decorative mold 80 is provided so that the lower portion 81 is positioned below the ground level GL.
図２に示されるように、鋼製基礎梁３０は複数の梁鋼材４０により構成される。鋼製基礎梁３０の全体形状は建築物本体１００の構造に応じて決められる。梁鋼材４０は複数の支持鋼材７０により支持される。一例では、複数の支持鋼材７０が鋼製基礎梁３０の長手方向に沿うように設置される。このため、支持鋼材７０を地盤Ｇに容易に設置できる。鋼製基礎梁３０の長手方向において隣り合う支持鋼材７０に所定の間隔が設けられる。このため、支持鋼材７０の数を削減できる。 As shown in FIG. 2, the steel foundation beam 30 is composed of a plurality of beam steel members 40. The overall shape of the steel foundation beam 30 is determined according to the structure of the building body 100. The beam steel material 40 is supported by a plurality of support steel materials 70. In one example, the plurality of supporting steel members 70 are installed along the longitudinal direction of the steel foundation beam 30. For this reason, the support steel material 70 can be easily installed on the ground G. A predetermined interval is provided between the supporting steel members 70 adjacent to each other in the longitudinal direction of the steel foundation beam 30. For this reason, the number of the supporting steel materials 70 can be reduced.
梁鋼材４０の種類は任意に選択できる。図１等に示される例では、全ての梁鋼材４０の種類はＨ形鋼である。このため、鋼製基礎梁３０の断面効率が高くなる。別の例では、梁鋼材４０の種類は溝形鋼、Ｉ形鋼、Ｔ形鋼、および、角柱鋼管である。溝形鋼は通常の溝形鋼、軽量溝形鋼、および、リップ溝形鋼に分類される。図１に示されるように、梁鋼材４０は第１フランジ４１、第２フランジ４２、および、ウェブ４３により構成される。梁鋼材４０には、第１フランジ４１の内面４１Ａ、第２フランジ４２の内面４２Ａ、および、ウェブ４３のウェブ面４３Ａ、４３Ｂに囲まれた凹部４４が形成される。第１フランジ４１の外面４１Ｂは支持鋼材７０と接触する。第２フランジ４２の外面４２Ｂは建築物本体１００と接触する。 The type of the beam steel material 40 can be arbitrarily selected.

In the example shown in FIG. 1 or FIG. 6 and the like, the types of all the support steel materials 70 are H-section steel. In another example, the types of the supporting steel materials 70 are channel steel, I-shaped steel, T-shaped steel, and prismatic steel pipe. The type of the support steel material 70 is preferably the same as the type of the beam steel material 40. For this reason, the productivity of the foundation structure 10 is improved.
図１または図６に示されるように、支持鋼材７０は一対のフランジ７１、７２、および、一対のフランジ７１、７２を連結するウェブ７３により構成される。支持鋼材７０には、第１フランジ７１の内面７１Ａ、第２フランジ７２の内面７２Ａ、および、ウェブ７３のウェブ面７３Ａに囲まれた凹部７４が形成される。第２フランジ７２は梁鋼材４０の第１フランジ４１と例えばボルトおよびナットによって結合される。支持鋼材７０の第２フランジ７２、および、梁鋼材４０の第１フランジ４１には、ボルトが挿入される複数の孔(図示略)が設けられる。第１フランジ７１の外面７１Ｂは補助層１１と接触する。第２フランジ７２の外面７２Ｂは梁鋼材４０の第１フランジ４１の外面４１Ｂと接触する。他方のウェブ面７３Ｂには、スチフナ７５が設けられる。一例では、スチフナ７５は他方のウェブ面７３Ｂにおいて、建築物２００の耐力壁(図示略)の下方と対応する部分に設けられる。 As shown in FIG. 1 or FIG. 6, the support steel material 70 includes a pair of flanges 71 and 72 and a web 73 that connects the pair of flanges 71 and 72. In the support steel material 70, an inner surface 71A of the first flange 71, an inner surface 72A of the second flange 72, and a recess 74 surrounded by the web surface 73A of the web 73 are formed. The second flange 72 is connected to the first flange 41 of the beam steel material 40 by, for example, bolts and nuts. The second flange 72 of the support steel material 70 and the first flange 41 of the beam steel material 40 are provided with a plurality of holes (not shown) into which bolts are inserted. The outer surface 71B of the first flange 71 is in contact with the auxiliary layer 11. The outer surface 72B of the second flange 72 is in contact with the outer surface 41B of the first flange 41 of the beam steel material 40. A stiffener 75 is provided on the other web surface 73B. In one example, the stiffener 75 is provided on the other web surface 73 </ b> B at a portion corresponding to the lower side of the bearing wall (not shown) of the building 200.
図６に示されるように、支持鋼材７０には鉄筋３００(図３参照)を支持する支持部６１、および、化粧型枠８０の下部８１(図１参照)と接触するアングル６２が取り付けられる。支持部６１は鉄筋３００を支持鋼材７０に溶接することなく取り付けることができるように設けられる。支持部６１によってウェブ７３と鉄筋３００とを容易に結合できる。鉄筋３００は例えばメッシュ筋である。支持部６１を構成する材料は鋼板である。支持部６１の構成は任意に選択できる。図６等に示される第１例では、支持部６１はウェブ７３の一方のウェブ面７３Ａに設けられるプレートである。第２例では、支持部６１はウェブ７３の一方のウェブ面７３Ａに設けられ、鉄筋３００を引っ掛けることができるフックである。支持部６１と一方のウェブ面７３Ａとの結合手段は溶接である。 As shown in FIG. 6, the support steel material 70 is attached with a support portion 61 that supports the reinforcing bar 300 (see FIG. 3) and an angle 62 that comes into contact with the lower portion 81 (see FIG. 1) of the decorative mold 80. The support portion 61 is provided so that the rebar 300 can be attached to the support steel material 70 without welding. The web 73 and the reinforcing bar 300 can be easily coupled by the support portion 61. The reinforcing bar 300 is, for example, a mesh bar. The material which comprises the support part 61 is a steel plate. The structure of the support part 61 can be selected arbitrarily.

For this reason, the reinforcing bar 300 can be more easily coupled. The insertion portion 61A is, for example, a groove or a hole. In the example shown in FIG. 6 and the like, the insertion portion 61A is a groove. The number of insertion parts 61A provided in the support part 61 is one or more. In the example shown in FIG. 6 and the like, the support portion 61 is provided with two insertion portions 61A into which the reinforcing bars 300 are inserted. The two insertion portions 61 </ b> A are inclined downward from the outside of the support steel material 70 toward the web 73. Since the rebar 300 is difficult to be removed from the insertion portion 61A, the state where the rebar 300 is supported by the support portion 61 is maintained. One ends 61AX of the two insertion portions 61A are open. For this reason, the reinforcing bar 300 can be easily inserted into the insertion portion 61A. The other ends 61AY of the two insertion portions 61A are closed. For this reason, the state in which the reinforcing bar 300 is supported by the support portion 61 is easily maintained.

The connecting portion 62A and the restricting portion 62B are portions separated by bending one plate. The connecting portion 62A extends in parallel with the flanges 71 and 72. The restricting portion 62 </ b> B extends in parallel with the web 73. The restricting portion 62 </ b> B is positioned outside the outer end portion of the support portion 61 with respect to the web 73 and contacts the decorative mold frame 80.
図２または図４に示されるように、鋼製基礎梁３０は建築物２００の出入口(図示略)が設けられる部分に形成される開口部３１を備える。ダウン基礎梁９０は開口部３１において、鋼製基礎梁３０の梁鋼材４０を支持する。このため、開口部３１における鋼製基礎梁３０の強度が高められる。なお、開口部３１は建築物２００の間仕切に対応する部分に設けることもできる。 As shown in FIG. 2 or FIG. 4, the steel foundation beam 30 includes an opening 31 formed in a portion where a doorway (not shown) of the building 200 is provided. The down foundation beam 90 supports the beam steel material 40 of the steel foundation beam 30 at the opening 31. For this reason, the strength of the steel foundation beam 30 in the opening 31 is increased. In addition, the opening part 31 can also be provided in the part corresponding to the partition of the building 200.
ダウン基礎梁９０は鋼材９０Ａにより構成される。鋼材９０Ａの種類は任意に選択できる。図４等に示される例では、鋼材９０Ａの種類はＨ形鋼である。別の例では、鋼材９０Ａの種類は溝形鋼、Ｉ形鋼、Ｔ形鋼、および、角柱鋼管である。鋼材９０Ａの種類は梁鋼材４０の種類、および、支持鋼材７０の種類の少なくとも一方と同じであることが好ましい。このため、基礎構造１０の生産性が向上する。鋼材９０Ａは第１フランジ９１、第２フランジ９２、および、ウェブ９３により構成される。鋼材９０Ａには、第１フランジ９１の内面９１Ａ、第２フランジ９２の内面９２Ａ、および、ウェブ９３のウェブ面９３Ａに囲まれた凹部９４が形成される。第１フランジ９１の外面９１Ｂは補助層１１と接触する。第２フランジ９２の外面９２Ｂは梁鋼材４０の第１フランジ４１の外面４１Ｂと接触する。基礎構造１０の高さ方向におけるダウン基礎梁９０の天面の位置と支持鋼材７０(図１参照)の天面の位置とは実質的に等しい。ダウン基礎梁９０の天面は第２フランジ９２の外面９２Ｂである。支持鋼材７０の天面の位置は第２フランジ７２の外面７２Ｂである。このため、建築物２００の出入口または間仕切において跨ぎ込みが生じない納まりとできる。図２に示されるように、鋼材９０Ａの長手方向の寸法ＬＡは支持鋼材７０の長手方向の寸法ＬＢよりも長い。このため、開口部３１における鋼製基礎梁３０の強度が一層高められる。 The down foundation beam 90 is made of a steel material 90A. The type of the steel material 90A can be arbitrarily selected. In the example shown in FIG. 4 and the like, the type of the steel material 90A is H-section steel. In another example, the types of the steel material 90A are channel steel, I-shaped steel, T-shaped steel, and prismatic steel pipe. The type of the steel material 90A is preferably the same as at least one of the type of the beam steel material 40 and the type of the support steel material 70. For this reason, the productivity of the foundation structure 10 is improved. The steel material 90 </ b> A includes a first flange 91, a second flange 92, and a web 93. In the steel material 90A, an inner surface 91A of the first flange 91, an inner surface 92A of the second flange 92, and a recess 94 surrounded by the web surface 93A of the web 93 are formed. The outer surface 91 </ b> B of the first flange 91 is in contact with the auxiliary layer 11. The outer surface 92B of the second flange 92 is in contact with the outer surface 41B of the first flange 41 of the beam steel material 40. The position of the top surface of the down foundation beam 90 in the height direction of the foundation structure 10 is substantially equal to the position of the top surface of the support steel material 70 (see FIG. 1). The top surface of the down foundation beam 90 is the outer surface 92 </ b> B of the second flange 92. The position of the top surface of the support steel material 70 is the outer surface 72 </ b> B of the second flange 72. For this reason, it can be set as the accommodation which does not straddle in the entrance / exit or the partition of the building 200. As shown in FIG. 2, the longitudinal dimension LA of the steel material 90 </ b> A is longer than the longitudinal dimension LB of the support steel material 70. For this reason, the strength of the steel foundation beam 30 in the opening 31 is further increased.
図７〜図９を参照して基礎構造１０の施工方法の一例について説明する。基礎構造１０の施工方法は第１工程〜第９工程を含む。第１工程は根切り工程の一例である。第３工程は設置工程の一例である。第５工程および第６工程は梁連結工程の一例である。 An example of the construction method of the foundation structure 10 is demonstrated with reference to FIGS. The construction method of the foundation structure 10 includes a first process to a ninth process. The first step is an example of a root cutting step. The third process is an example of an installation process. The fifth step and the sixth step are an example of a beam connecting step.
図７に示されるように、第１工程では、地盤Ｇに掘削溝ＧＡが形成される。第２工程では、掘削溝ＧＡの根切り底ＧＢに補助層１１として砕石層、または、砕石層および捨てコンクリート層が形成される。砕石層の表面は転圧機により転圧される。図８に示されるように、第３工程では、複数の支持鋼材７０が補助層１１に載せられる。第４工程では、支持部６１の挿入部６１Ａに鉄筋３００が挿入される。第５工程では、支持鋼材７０の第２フランジ７２に型枠支持部材５０が結合された梁鋼材４０が載せられる。第６工程では、梁鋼材４０の第１フランジ４１と複数の支持鋼材７０の第２フランジ７２とがボルトおよびナットによって連結される。図９に示されるように、第７工程では、化粧型枠８０が型枠支持部材５０に結合される。第８工程では、掘削溝ＧＡのうち、化粧型枠８０よりも外側の部分が埋め戻される。第９工程では、化粧型枠８０によって囲まれる領域にコンクリートが流し込まれ、コンクリート製基礎２０が打設される。コンクリート製基礎２０は梁鋼材４０の第１フランジ４１よりも高い位置まで設けられる。梁鋼材４０の第１フランジ４１と支持鋼材７０の第２フランジ７２との結合部分がコンクリート製基礎２０によって覆われるため、基礎構造１０の強度が高められる。なお、コンクリートが流し込まれたときの化粧型枠８０の支持鋼材７０から離間する方向の移動は第８工程で埋め戻された土によって規制される。第１０工程では、コンクリート製基礎２０上に仕上層４００(図１参照)が設けられ、フロアレベルＦＬが形成される。 As shown in FIG. 7, in the first step, the excavation groove GA is formed in the ground G. In the second step, a crushed stone layer, or a crushed stone layer and a discarded concrete layer are formed as the auxiliary layer 11 on the root cut GB of the excavation groove GA. The surface of the crushed stone layer is rolled by a rolling machine. As shown in FIG. 8, in the third step, a plurality of support steel materials 70 are placed on the auxiliary layer 11. In the fourth step, the reinforcing bar 300 is inserted into the insertion portion 61 </ b> A of the support portion 61. In the fifth step, the beam steel material 40 to which the formwork support member 50 is coupled is placed on the second flange 72 of the support steel material 70. In the sixth step, the first flange 41 of the beam steel material 40 and the second flanges 72 of the plurality of support steel materials 70 are connected by bolts and nuts. As shown in FIG. 9, in the seventh step, the decorative mold 80 is coupled to the mold support member 50. In the eighth step, a portion of the excavation groove GA outside the decorative mold 80 is backfilled. In the ninth step, concrete is poured into a region surrounded by the decorative mold 80, and the concrete foundation 20 is placed. The concrete foundation 20 is provided up to a position higher than the first flange 41 of the beam steel material 40. Since the joint portion between the first flange 41 of the beam steel member 40 and the second flange 72 of the support steel member 70 is covered with the concrete foundation 20, the strength of the foundation structure 10 is increased. Note that the movement of the decorative mold 80 in the direction away from the support steel material 70 when the concrete is poured is regulated by the soil backfilled in the eighth step. In the tenth step, a finishing layer 400 (see FIG. 1) is provided on the concrete foundation 20, and a floor level FL is formed.
基礎構造１０の作用および効果について説明する。
支持鋼材７０によってグランドレベルＧＬに対する鋼製基礎梁３０の高さ方向の位置を保持した状態でコンクリート製基礎２０を打設することにより、支持鋼材７０を介して地盤Ｇと鋼製基礎梁３０とが結合されるため、鋼製基礎梁３０にアンカーボルトを取り付ける必要がない。このため、基礎構造１０の施工時間を短縮できる。さらに、基礎構造１０では、コンクリート製基礎２０は主に、鋼製基礎梁３０から地盤Ｇへ圧縮力を伝達させるための補助的な役割を担う。躯体１１０と鋼製基礎梁３０とがボルト１３０によって結合されているため、躯体１１０に含まれる耐力壁の柱脚等に発生する引き抜き力は鋼製基礎梁３０に対して曲げ応力およびせん断応力として作用する。基礎構造１０では、これらの応力に抵抗できるように鋼製基礎梁３０の断面形状が選定されているため、鋼製基礎梁３０でつり合い系が成立する。このため、鋼製基礎梁３０とコンクリート製基礎２０との結合にアンカーボルトを必要としない。また、第１工程で形成する掘削溝ＧＡの根切り底ＧＢの幅を調整することにより、地盤Ｇの耐力に応じたベース幅を簡単に確保できる。
The operation and effect of the foundation structure 10 will be described.
By placing the concrete foundation 20 in a state where the height direction of the steel foundation beam 30 with respect to the ground level GL is held by the support steel material 70, the ground G and the steel foundation beam 30 are interposed via the support steel material 70. Therefore, it is not necessary to attach anchor bolts to the steel foundation beam 30. For this reason, the construction time of the foundation structure 10 can be shortened. Further, in the foundation structure 10, the concrete foundation 20 mainly plays an auxiliary role for transmitting a compressive force from the steel foundation beam 30 to the ground G. Since the frame 110 and the steel foundation beam 30 are coupled by the bolt 130, the pulling force generated in the column base of the load bearing wall included in the frame 110 is applied to the steel foundation beam 30 as bending stress and shear stress. Works. In the foundation structure 10, since the cross-sectional shape of the steel foundation beam 30 is selected so as to resist these stresses, a balance system is established by the steel foundation beam 30. For this reason, an anchor bolt is not required for the connection between the steel foundation beam 30 and the concrete foundation 20. Moreover, the base width according to the proof stress of the ground G can be easily ensured by adjusting the width of the root cut bottom GB of the excavation groove GA formed in the first step.
(第２実施形態)
第２実施形態の基礎構造１０は図１に示される化粧型枠８０および支持部６１に代えて、図１０に示される化粧型枠１８０および複数の支持部１６１を備える。化粧型枠１８０は例えば、メッシュ状の型枠である。化粧型枠１８０は例えば、鋼製メッシュである。化粧型枠１８０は複数の鉄筋１８１、および、複数の鉄筋１８１に溶接されるメッシュ筋１８２を備える。化粧型枠１８０は下部１８０ＡがグランドレベルＧＬよりも下方に位置するように設けられる。化粧型枠１８０は上部１８０ＢがグランドレベルＧＬよりも上方、かつ、梁鋼材４０の第２フランジ４２よりも下方に位置するように設けられる。化粧型枠１８０の表面には、仕上層１９０が設けられる。仕上層１９０は例えばモルタル層である。化粧型枠１８０がメッシュ状の型枠であるため、化粧型枠１８０の表面に仕上層１９０を容易に形成できる。
