<P>PROBLEM TO BE SOLVED: To provide a foundation structure of a steel column base of a building simplified in structure by reducing the volume of rising reinforcements. <P>SOLUTION: A fixing plate 6 for an anchor bolt 7 is disposed on the lower side of a beam lower end reinforcement 2. Since a cone-shaped crack occurs on the lower side of the beam lower end reinforcement 2, the fixing part of the beam lower end reinforcement 2 is not divided and the anchor bolt 7 can be fixed to a foundation concrete. Since the anchor bolt 7 can be safely and securely fixed to a concrete foundation 9 by using a foundation beam reinforcement 4, the anchor bolt 7 can be safely and securely fixed to the concrete foundation 9 by merely installing minimum rising reinforcements 15 and hoop reinforcements 16 specified in standards. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、建築物の鉄骨柱脚の基礎構造に関する。   The present invention relates to a foundation structure for a steel column base of a building.

従来、図３乃至図５に示すように、梁上端筋１と梁下端筋２およびあばら筋３からなる基礎梁筋４を配筋し基礎梁５を構築する際、所定の位置に、下端部に定着板６を取付けた複数本（図例では４本）のアンカーボルト７を設置し、その後コンクリートを打設し、基礎梁筋４が埋設された基礎梁５、基礎梁筋４とアンカーボルト７および定着板６が埋設された基礎柱８、からなるコンクリート基礎９を構築し、コンクリート基礎９の基礎柱８部の上に突出するアンカーボルト７の上端ボルト部７ａを用い、基礎柱８部に鉄骨柱１０を接合してなる露出型の鉄骨柱脚の基礎構造がある。この場合、基礎柱８部における基礎コンクリートの上にはモルタル１１が水平に打設される。そして、モルタル１１の上に鉄骨柱１０の下端に溶接されたベースプレート１２が設置され、ベースプレート１２の孔にアンカーボルト７の上端ボルト部７ａが挿入され、ベースプレート１２の上面に突出する上端ボルト部７ａにワッシャー１３を介してナット１４を螺合し、基礎柱８部に鉄骨柱１０を接合している。   Conventionally, as shown in FIGS. 3 to 5, when the foundation beam 5 is constructed by arranging the foundation beam 5 composed of the beam upper reinforcement 1, the beam lower reinforcement 2, and the rib 3, the lower end portion is located at a predetermined position. A plurality of anchor bolts 7 (four in the illustrated example) with fixing plates 6 attached thereto are installed, and then concrete is cast, and the foundation beam 5 in which the foundation beam 4 is embedded, the foundation beam 4 and the anchor bolt. 7 and a foundation column 8 in which a fixing plate 6 is embedded, a concrete foundation 9 is constructed, and an upper end bolt portion 7a of an anchor bolt 7 projecting on the foundation column 8 portion of the concrete foundation 9 is used, and 8 parts of the foundation column There is a foundation structure of an exposed steel column base formed by joining a steel column 10 to the above. In this case, the mortar 11 is placed horizontally on the foundation concrete in the 8 parts of the foundation pillar. Then, a base plate 12 welded to the lower end of the steel column 10 is installed on the mortar 11, and the upper end bolt portion 7 a of the anchor bolt 7 is inserted into the hole of the base plate 12, and the upper end bolt portion 7 a protruding from the upper surface of the base plate 12. A nut 14 is screwed to the steel column 10 through a washer 13 to join the steel column 10 to the 8th portion of the foundation column.

上記のような露出型の鉄骨柱脚の基礎構造では、通常、鉄骨柱１０に曲げモーメント等が作用すると、ベースプレート１２を介しアンカーボルト７に引抜き力がかかり、その引抜き力により基礎柱８部の基礎コンクリートにかかる応力がその基礎コンクリートの耐力を超えると、アンカーボルト７の定着板６付近から基礎柱８部の基礎コンクリートにコーン状割れを生じる。従来より露出型の鉄骨柱脚の基礎構造では、図３及び図４に示すように、基礎柱８部の基礎コンクリート中におけるアンカーボルト７の外周に、立上り筋１５およびフープ筋１６からなる基礎柱筋１７を埋設し、コーン状割れによる基礎柱８部の破壊を防止している。なお、立上り筋１５は所定長さの余長部１５ａを有し、余長部１５ａが立上り部に対して略直角に折曲げられ、基礎柱８部の下端部に略水平に埋設されており、立上り筋１５を余長部１５ａにより基礎柱８部の基礎コンクリートに定着させている。   In the foundation structure of the exposed steel column base as described above, when a bending moment or the like acts on the steel column 10, a pulling force is applied to the anchor bolt 7 via the base plate 12, and the pulling force causes the 8 parts of the basic column to be When the stress applied to the foundation concrete exceeds the proof stress of the foundation concrete, a cone-like crack is generated in the foundation concrete of the 8 part of the foundation column from the vicinity of the fixing plate 6 of the anchor bolt 7. Conventionally, in the foundation structure of the exposed steel column base, as shown in FIG. 3 and FIG. 4, the foundation column comprising the rising bars 15 and the hoop bars 16 on the outer periphery of the anchor bolt 7 in the foundation concrete of the foundation column 8 part. The line 17 is embedded to prevent the breakage of the 8 parts of the foundation pillar due to the cone crack. The rising muscle 15 has a surplus length portion 15a having a predetermined length, the surplus length portion 15a is bent at a substantially right angle with respect to the rising portion, and is embedded substantially horizontally at a lower end portion of the base pillar 8 portion. The rising bars 15 are fixed to the foundation concrete of the foundation pillar 8 part by the extra length part 15a.

また、立上り筋１５と同様にアンカーボルト７についてもその下端ボルト部７ｂに一対のロックナット１８を介し定着板６を水平に取付け、アンカーボルト７を定着板６により基礎柱８部の基礎コンクリートに定着させると共に、アンカーボルト７の引抜き耐力を大幅に増大させているが、従来の露出型の鉄骨柱脚の基礎構造では、図３に示すように、定着板６は、基礎柱８部の基礎コンクリート中において、基礎梁筋４の梁下端筋２よりも上方に配置（埋設）されている。
特開平５−２５８３２号公報 特開平７−１０２６３９号公報 特開２００３−２３９３８１号公報 Similarly to the rising bar 15, the anchor bolt 7 is also attached to the lower end bolt portion 7 b of the anchor bolt 7 horizontally via a pair of lock nuts 18. In addition to fixing, the anchoring strength of the anchor bolt 7 is greatly increased. However, in the conventional foundation structure of the exposed steel column base, as shown in FIG. In the concrete, it is arranged (embedded) above the beam lower bar 2 of the foundation beam 4.
Japanese Patent Laid-Open No. 5-25832 JP-A-7-10239 Japanese Patent Laid-Open No. 2003-239381

基礎柱８部における基礎コンクリート中において、定着板６が、梁下端筋４よりも上方に配置されている従来の構造では、コーン状割れが梁下端筋４よりも上方に生じ、定着板６と梁下端筋２の定着部が分断されるので、アンカーボルト７を基礎コンクリートに定着できない。アンカーボルト７を基礎コンクリートに安全確実に定着させるためには、アンカーボルト７の外周に多くの立上り筋１５およびフープ筋１６を設置すると共に、立上り筋１５の余長Ｌも長くする必要があるので、コンクリート基礎９を構築する際の配筋が困難になるという問題があった。   In the conventional concrete in which the fixing plate 6 is arranged above the beam lower end reinforcement 4 in the foundation concrete in the base column 8 part, the cone-shaped crack is generated above the beam lower end reinforcement 4, and the fixing plate 6 and Since the fixing portion of the beam lower end reinforcement 2 is divided, the anchor bolt 7 cannot be fixed to the foundation concrete. In order to securely and securely anchor the anchor bolt 7 to the foundation concrete, it is necessary to install many rising muscles 15 and hoop muscles 16 on the outer periphery of the anchor bolt 7 and to make the extra length L of the rising muscle 15 longer. There has been a problem that the reinforcement of the concrete foundation 9 becomes difficult.

本発明は、上記の問題を解決するために、梁上端筋と梁下端筋およびあばら筋からなる基礎梁筋と、下端部に定着板を取付けた複数本のアンカーボルトと、立上り筋およびフープ筋からなる基礎柱筋とが埋設されたコンクリート基礎に、上記複数本のアンカーボルトを用いて鉄骨柱を接合してなる露出型の鉄骨柱脚の基礎構造において、上記定着板を上記梁下端筋よりも下方に配置したものである。   In order to solve the above-mentioned problem, the present invention provides a basic beam bar composed of a beam upper bar, a beam lower bar and a rib, a plurality of anchor bolts having a fixing plate attached to the lower end, a rising bar and a hoop bar. In the foundation structure of the exposed steel column base, in which the steel column is joined to the concrete foundation embedded with the foundation column reinforcement composed of Is also arranged below.

定着板が梁下端筋よりも下方に配置される本発明の構造では、コーン状割れが梁下端筋よりも下方に生じ、定着板と梁下端筋の定着部が分断されることがないので、アンカーボルト７を基礎コンクリートに定着できる。   In the structure of the present invention in which the fixing plate is disposed below the beam lower bar, the cone-shaped crack is generated below the beam lower bar, and the fixing plate and the fixing part of the beam lower bar are not divided. Anchor bolt 7 can be fixed to the foundation concrete.

本発明によれば、定着板が梁下端筋よりも下方に配置されているために、基礎梁筋を用いてアンカーボルトをコンクリート基礎に安全確実に定着させることができる。よって、基準等で定められた最小限度の立上り筋およびフープ筋の設置のみで、アンカーボルトをコンクリート基礎に安全確実に定着させることができる。したがって、露出型の鉄骨柱脚の基礎構造における立上り筋およびフープ筋の減量と、立上り筋の余長の短縮が可能になり、基礎構造の簡略化を図ることができ、コンクリート基礎を構築する際の配筋を従来に比べ簡単に行うことができる。   According to the present invention, since the fixing plate is arranged below the beam lower end reinforcement, the anchor bolt can be safely and reliably fixed to the concrete foundation using the foundation beam reinforcement. Therefore, the anchor bolt can be securely and securely fixed to the concrete foundation only by installing the minimum riser and hoop reinforcements defined by the standards. Therefore, it is possible to reduce the riser and hoop muscles in the foundation structure of the exposed steel column base and to shorten the extra length of the riser, simplify the foundation structure, and build a concrete foundation. This arrangement can be performed more easily than before.

以下、本発明の実施の形態について図面を参照して説明する。図１は本発明の実施の形態に係る露出型の鉄骨柱脚の基礎構造を示す縦断面図（図３に対応）、図２は図１のａ−ａ断面図（図４に対応）である。なお、図３乃至図５に示した従来の露出型の鉄骨柱脚の基礎構造と同一部分には同一符号を付し、その詳しい説明を省略し、相違する部分について説明する。また、図１のｂ−ｂ断面図は図４と同一のため省略している。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a longitudinal sectional view (corresponding to FIG. 3) showing the basic structure of an exposed steel column base according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line aa in FIG. 1 (corresponding to FIG. 4). is there. The same parts as those of the basic structure of the conventional exposed steel column base shown in FIGS. 3 to 5 are denoted by the same reference numerals, detailed description thereof will be omitted, and different parts will be described. 1 is omitted because it is the same as FIG.

図１及び図２に示すように、本発明の実施の形態に係る露出型の鉄骨柱脚の基礎構造では、アンカーボルト７が、基礎柱８部の基礎コンクリート中において、アンカーボルト７の下端ボルト部７ｂに一対のロックナット１８を介して水平に取り付けた定着板６を、基礎梁筋４の梁下端筋２よりも下方に配置できる長さ（定着長）を有しており、定着板６が、基礎柱８部の基礎コンクリート中において、基礎梁筋４の梁下端筋２よりも下方に配置（埋設）されている。なお、図１において２０は基礎梁５部と基礎柱８部の接合部に設けたハンチ部であり、このハンチ部２０を用い基礎梁５部と基礎柱８部の接合部の耐力を大きくすると共に、アンカーボルト７の定着長を確保している。   As shown in FIGS. 1 and 2, in the foundation structure of the exposed steel column base according to the embodiment of the present invention, the anchor bolt 7 is the lower end bolt of the anchor bolt 7 in the foundation concrete of the foundation column 8 part. The fixing plate 6 that is horizontally attached to the portion 7 b via a pair of lock nuts 18 has a length (fixing length) that can be disposed below the beam lower end 2 of the foundation beam 4, and the fixing plate 6. However, it is disposed (embedded) below the bottom beam 2 of the foundation beam 4 in the foundation concrete of the base column 8 part. In FIG. 1, reference numeral 20 denotes a haunch portion provided at a joint portion between the base beam 5 portion and the base column 8 portion, and the proof strength of the joint portion between the base beam 5 portion and the base column 8 portion is increased by using the haunch portion 20. At the same time, the fixing length of the anchor bolt 7 is secured.

以上の構造において、鉄骨柱１０に曲げモーメント等が作用すると、ベースプレート１２を介しアンカーボルト７に引抜き力がかかり、その引抜き力により基礎柱８部の基礎コンクリートに応力がかかるが、定着板６が、基礎柱８部の基礎コンクリート中において、基礎梁筋４の梁下端筋２よりも下方に配置されているので、上記応力は定着板６および梁下端筋２を介し基礎梁５部の基礎コンクリートおよび基礎梁筋４に円滑に分散伝達される。また、基礎柱８部の基礎コンクリート中にコーン状割れが生じたとしても、それは梁下端筋２よりも下方に生じ、定着板６と梁下端筋２の定着部が分断されることがなく、上記応力の分散伝達はそのまま継続して行われると共に、アンカーボルト７を基礎柱８部の基礎コンクリートに定着させることができる。   In the above structure, when a bending moment or the like acts on the steel column 10, a pulling force is applied to the anchor bolt 7 through the base plate 12, and stress is applied to the foundation concrete of the base column 8 part by the pulling force. In the foundation concrete of the foundation column 8 part, the stress is arranged below the beam bottom reinforcement 2 of the foundation beam 4, so the stress is applied to the foundation concrete of the foundation beam 5 part via the fixing plate 6 and the beam bottom reinforcement 2. And it is smoothly distributed and transmitted to the foundation beam 4. Moreover, even if a cone-like crack occurs in the foundation concrete of the foundation column 8 part, it occurs below the beam lower bar 2 and the fixing part of the fixing plate 6 and the beam lower bar 2 is not divided. The distributed transmission of the stress is continuously performed as it is, and the anchor bolt 7 can be fixed to the foundation concrete of the foundation column 8 part.

よって、定着板６が、基礎柱８部の基礎コンクリート中において、基礎梁筋４の梁下端筋２よりも上方に配置される従来の露出型の鉄骨柱脚の基礎構造では、図４に示すように、アンカーボルト７を基礎柱８部の基礎コンクリートに安全確実に定着させるために、基礎柱８部の基礎コンクリート中におけるアンカーボルト７の外周に、長さＬ１の余長部１５ａを有する立上り筋１５が１６本密に設置されているのに対し、定着板６が、基礎柱８部の基礎コンクリート中において、基礎梁筋４の梁下端筋２よりも下方に配置される本発明の実施の形態に係る露出型の鉄骨柱脚の基礎構造では、図２に示すように、基準等で定められた最小限度の立上り筋１５の設置、本実施の形態の場合、従来の構造の半分の８本の設置で、しかも、余長部１５ａの長さも従来の構造よりも短いＬ２（Ｌ１＞Ｌ２）に短縮された立上り筋１５の設置で、アンカーボルト７を基礎柱８部の基礎コンクリートに安全確実に定着させることができる。   Therefore, in the foundation structure of the conventional exposed steel column base in which the fixing plate 6 is disposed above the beam lower end reinforcement 2 of the foundation beam reinforcement 4 in the foundation concrete of the foundation pillar 8 part, it is shown in FIG. Thus, in order to securely and securely anchor the anchor bolt 7 to the foundation concrete of the foundation pillar 8 part, the rising having the extra length part 15a of the length L1 on the outer periphery of the anchor bolt 7 in the foundation concrete of the foundation pillar 8 part Implementation of the present invention, in which 16 streaks 15 are densely arranged, the fixing plate 6 is disposed below the bottom beam 2 of the foundation beam 4 in the foundation concrete of the base column 8 part. As shown in FIG. 2, in the foundation structure of the exposed steel column base according to the form of the present invention, the minimum riser 15 defined by the standard or the like is installed, and in the case of this embodiment, half of the conventional structure. Eight installations, and extra length 15 The length of the in installation of rising muscle 15 which is reduced to L2 (L1> L2) shorter than the conventional structure, the anchor bolts 7 can be made to secure fixing to the foundation concrete foundation pillars 8 parts.

したがって、露出型の鉄骨柱脚の基礎構造における立上り筋１５の減量およびそれに伴うフープ筋１６の減量と、立上り筋１５の余長Ｌの短縮が可能になり、基礎構造の簡略化を図ることができ、コンクリート基礎９を構築する際の配筋を従来に比べ簡単に行うことができる。   Therefore, it is possible to reduce the rising muscle 15 in the foundation structure of the exposed steel column base and the hoop muscle 16 accordingly, and to shorten the extra length L of the rising muscle 15, thereby simplifying the foundation structure. It is possible to arrange the bars when constructing the concrete foundation 9 more easily than in the past.

また、コンクリート基礎９の基礎梁５部の曲げ耐力は鉄骨柱１０の曲げ耐力と同等以上であるので、基礎梁筋４の安全確実な定着力が確保でき、柱脚部（アンカーボルト７を含む基礎柱８部）と基礎梁５部との接合部条件が成立すれば、立上り筋１５がなくてもアンカーボルト７をコンクリート基礎９に安全確実に定着させることも可能になる（柱脚部と基礎梁との接合条件「日本建築学会；鉄筋コンクリート造建物の靭性保証型耐震設計指針・同解説」、立上り筋比「日本建築学会；鉄筋コンクリート構造計算基準・同解説」より」）。   Further, since the bending strength of the foundation beam 5 portion of the concrete foundation 9 is equal to or greater than the bending strength of the steel column 10, a safe and secure fixing force of the foundation beam 4 can be secured, and the column base portion (including the anchor bolt 7). If the joint condition between the foundation column (8 parts) and the foundation beam (5 parts) is satisfied, the anchor bolt 7 can be secured to the concrete foundation 9 safely and without the riser 15 (column base and Joining conditions with foundation beams "The Architectural Institute of Japan; Guideline for the seismic design of toughness-proof reinforced concrete buildings and explanation", Rise ratio "The Architectural Institute of Japan;

なお、本実施の形態では鉄骨柱１０として角形鋼管を用いた場合を示したが、円形鋼管やＨ形鋼を用いてもよい。また、本実施の形態では側柱の柱脚部を示したが、本発明は隅柱の柱脚部にも適用することができる。   In addition, although the case where a square steel pipe was used as the steel column 10 was shown in this Embodiment, you may use a round steel pipe and H-section steel. Moreover, although the column base part of the side column was shown in this Embodiment, this invention is applicable also to the column base part of a corner pillar.
