Description

本発明は、カーポートやテラスなどを構成する支柱を地面に立設するための支柱基礎構造に関し、特に支柱の下端部に取付金具を設けると共にコンクリート基礎材を打設してなる支柱基礎構造に関する。   The present invention relates to a column foundation structure for standing a column that constitutes a carport or a terrace on the ground, and more particularly to a column foundation structure in which a mounting bracket is provided at the lower end of the column and a concrete foundation material is cast. .

カーポートやテラスなどの構造物においては、支柱を地面に立設し、立設された支柱によって梁などを支持するようにしている。このため、支柱は地面に強固に支持される必要があり、そのための構造として支柱基礎構造が用いられる。支柱基礎構造としては、支柱の下端部付近の領域にコンクリート基礎材を打設してなるものが知られている。   In a structure such as a carport or a terrace, a column is erected on the ground, and a beam or the like is supported by the column that is erected. For this reason, a support | pillar needs to be firmly supported by the ground, and a support | pillar foundation structure is used as a structure for it. As a support foundation structure, a structure in which a concrete foundation material is placed in a region near the lower end of the support is known.

通常、支柱はコンクリート基礎材の平面視における中央部に埋設され、これによって立設強度を充分に確保することができる。しかし、住宅事情の変化に伴い狭小地化が進んだため、少しでもスペースを有効に使いたいという要望が高まり、支柱の立設強度を確保しつつコンクリート基礎材の中央から一方側に偏った位置に支柱を埋設する構造が望まれている。そして、このような支柱基礎構造としては例えば特許文献1に挙げるようなものがある。
特開2006−152586号公報
Usually, a support | pillar is embed | buried under the center part in the planar view of a concrete foundation material, and, thereby, sufficient standing strength can be ensured. However, as the housing conditions have changed, the land has become narrower, and there has been a growing demand for effective use of space even as little as possible. It is desirable to have a structure in which a support is embedded in And as such a support | pillar foundation structure, there exists a thing as listed in patent document 1, for example.
JP 2006-152586 A

従来の技術においては、支柱の下端部に配置された偏芯基礎部材を取付け、この偏芯基礎部材を含めて支柱の下端部をコンクリート基礎材の中に埋設することにより、強度を確保しながら支柱を偏芯させることとしていた。しかし、従来の支柱基礎構造は、偏芯基礎部材の構造が比較的複雑であり、部品数も多いためにコストが高くなるという問題があった。また、偏芯基礎部材は支柱を偏芯させる場合にのみ用いられるものであって、支柱もを通常のようにコンクリート基礎材の中央部に埋設する場合には使えないものであることから、用途が限定され、さらに高コスト化を招くものとなっていた。   In the conventional technology, while attaching an eccentric foundation member arranged at the lower end of the column, and embedding the lower end of the column including the eccentric foundation member in the concrete foundation, while ensuring strength The support was supposed to be eccentric. However, the conventional strut base structure has a problem that the structure of the eccentric base member is relatively complicated and the number of parts is large, resulting in an increase in cost. In addition, the eccentric foundation member is used only when the column is eccentric, and the column can not be used when embedding the column in the center of the concrete foundation as usual. However, the cost was further increased.

本発明は、上記課題を解決すべくなされたものであり、支柱の埋設位置をコンクリート基礎材の中央部から偏芯させても確実に強度を確保でき、かつ低コストな支柱基礎構造を提供することを目的とする。   The present invention has been made to solve the above problems, and provides a strut foundation structure that can reliably ensure strength even if the embedding position of the strut is decentered from the center portion of the concrete foundation material and that is low in cost. For the purpose.

上記課題を解決するため、本発明に係る支柱基礎構造は、支柱の下端部にコンクリート基礎材が打設されることで、前記支柱が地面に立設される支柱基礎構造において、
前記支柱には前記コンクリート基礎材に埋め込まれる領域に固定金具が装着され、該固定金具は前記支柱の側面を構成する第1の面に取付けられる第1金具と、前記支柱の側面のうち前記第1の面と対向する第2の面に取付けられる第2金具とからなり、
前記第1金具は、前記第1の面及び該第1の面と直交する前記支柱の側面に対し抱き込むように当接する凹部と、該凹部の開口側端部から略直角方向に延びる平面部とを有してなり、前記第2金具は、前記第2の面に当接する当接面と、該当接面から外方に延びて前記平面部と対向する対向面とが平板状に形成されてなり、前記平面部と対向面は所定間隔を有して対向すると共に締結具により連結固定されてなることを特徴として構成されている。
In order to solve the above-mentioned problems, the column foundation structure according to the present invention is a column foundation structure in which the column is erected on the ground by placing a concrete foundation material at the lower end of the column.
A fixing bracket is mounted on the column in a region embedded in the concrete base material, and the fixing bracket is attached to a first surface constituting a side surface of the column and the first of the side surfaces of the column. A second fitting attached to the second surface opposite to the first surface,
The first metal fitting includes a concave portion that comes into contact with the first surface and a side surface of the support that is orthogonal to the first surface, and a flat portion that extends in a substantially perpendicular direction from the opening-side end of the concave portion. The second metal fitting is formed in a flat plate shape with a contact surface that contacts the second surface and an opposing surface that extends outward from the contact surface and faces the flat portion. The plane portion and the opposed surface are opposed to each other with a predetermined distance and are connected and fixed by a fastener.

また、本発明に係る支柱基礎構造は、前記支柱は上端部で一方向側に向かって延びる梁を支持し、前記第1の面または第2の面のいずれか一方は前記梁の延びる方向に面していることを特徴として構成されている。   Moreover, the support | pillar foundation structure which concerns on this invention supports the beam which the said support | pillar extends toward one direction side by an upper end part, and either one of the said 1st surface or the 2nd surface is in the extension direction of the said beam. It is structured to be facing.

さらに、本発明に係る支柱基礎構造は、前記支柱は前記コンクリート基礎材の中央よりも一方側に偏って配置され、前記第1の面は前記コンクリート基礎材の中央に対して偏った側に面するように配置されることを特徴として構成されている。   Furthermore, in the column foundation structure according to the present invention, the column is arranged to be deviated to one side from the center of the concrete foundation material, and the first surface is a surface to the side deviated from the center of the concrete foundation material. It is configured to be arranged as described above.

さらにまた、本発明に係る支柱基礎構造は、前記固定金具は前記支柱のコンクリート基礎材に埋め込まれる領域のうち上部と下部にそれぞれ装着されることを特徴として構成されている。   Still further, the support foundation structure according to the present invention is characterized in that the fixing metal fittings are respectively attached to an upper part and a lower part of a region embedded in the concrete foundation material of the support pillar.

そして、本発明に係る支柱基礎構造は、前記固定金具は前記支柱のコンクリート基礎材に埋め込まれる領域のうち上端部から下端部に渡る上下方向幅を有してなることを特徴として構成されている。   And the support | pillar foundation structure which concerns on this invention is comprised by the said fixing bracket having the up-down direction width | variety ranging from an upper end part to a lower end part among the area | regions embedded in the concrete foundation material of the said support | pillar. .

本発明に係る支柱基礎構造によれば、支柱にはコンクリート基礎材に埋め込まれる領域に固定金具が装着され、固定金具は支柱の第1の面に取付けられる第1金具と、支柱の第2の面に取付けられる第2金具とからなり、第1金具は、第1の面及び該第1の面と直交する支柱の側面に対し抱き込むように当接する凹部と、凹部の開口側端部から略直角方向に延びる平面部とを有してなり、第2金具は、第2の面に当接する当接面と、当接面から外方に延びて平面部と対向する対向面とが平板状に形成されてなり、平面部と対向面は所定間隔を有して対向すると共に締結具により連結固定されてなることにより、第1金具により固定金具の支柱に対する固定強度を充分に確保し、かつ平面部と対向面の間の隙間にコンクリートが充填されるので平面部と対向面により支柱の立設強度を大きくすることができるので、支柱の埋設位置をコンクリート基礎材の中央部から偏芯させても確実に強度を確保できる。また、固定金具は第1金具と第2金具で支柱を挟持し連結固定されるだけの簡易な構成であることから、部品数が少なく低コスト化を図ることができる。さらに、支柱をコンクリート基礎材の中央部に埋設する場合でも固定金具を用いることができるので、支柱を立設する立地条件にかかわらず本構造を用いることができる。   According to the support foundation structure according to the present invention, the support is provided with a fixing bracket in the region embedded in the concrete foundation material, and the fixing bracket is attached to the first surface of the support and the second support of the support. The first metal fitting is formed from a first surface and a concave portion that comes into contact with the first surface and a side surface of the support perpendicular to the first surface, and an opening-side end portion of the concave portion. The second metal fitting has a flat surface with a contact surface that contacts the second surface and a facing surface that extends outward from the contact surface and faces the flat portion. The flat portion and the facing surface are opposed to each other with a predetermined interval and are connected and fixed by a fastener, thereby sufficiently securing the fixing strength of the fixing bracket to the support column by the first bracket, And because the concrete is filled in the gap between the flat part and the opposite surface It is possible to increase the standing 設強 of the strut by surface and the facing surface, the buried position of the strut can be secured reliably strength by eccentric from the center of the concrete foundation material. In addition, since the fixing bracket has a simple configuration in which the first bracket and the second bracket are sandwiched and connected and fixed, the number of components is small and the cost can be reduced. Further, since the fixing bracket can be used even when the support column is embedded in the center portion of the concrete foundation material, the present structure can be used regardless of the location conditions where the support column is erected.

また、本発明に係る支柱基礎構造によれば、支柱は上端部で一方向側に向かって延びる梁を支持し、第1の面または第2の面のいずれか一方は梁の延びる方向に面していることにより、梁によって支柱にかかる荷重を確実に第1金具の平面部と第2金具の対向面で受けることができる。   Moreover, according to the support | pillar foundation structure which concerns on this invention, a support | pillar supports the beam extended toward one direction side by an upper end part, and either one of a 1st surface or a 2nd surface is a surface in the direction where a beam extends. By doing so, the load applied to the column by the beam can be reliably received by the flat surface of the first metal fitting and the opposing surface of the second metal fitting.

さらに、本発明に係る支柱基礎構造によれば、支柱はコンクリート基礎材の中央よりも一方側に偏って配置され、第1の面はコンクリート基礎材の中央に対して偏った側に面するように配置されることにより、第1の面に取付けられる第1金具の平面部とコンクリート基礎材の側面との距離を確保でき、より立設強度を向上させることができる。   Furthermore, according to the column foundation structure according to the present invention, the column is arranged so as to be biased to one side with respect to the center of the concrete foundation material, and the first surface faces the side biased with respect to the center of the concrete foundation material. By arrange | positioning, the distance of the plane part of the 1st metal fitting attached to a 1st surface and the side surface of a concrete foundation material can be ensured, and standing installation strength can be improved more.

さらにまた、本発明に係る支柱基礎構造によれば、固定金具は支柱のコンクリート基礎材に埋め込まれる領域のうち上部と下部にそれぞれ装着されることにより、固定金具による支柱の立設強度をより向上させることができる。   Still further, according to the support foundation structure according to the present invention, the fixing brackets are respectively attached to the upper part and the lower part of the region embedded in the concrete foundation material of the support pillars, thereby further improving the standing strength of the support pillars by the fixing brackets. Can be made.

そして、本発明に係る支柱基礎構造によれば、固定金具は支柱のコンクリート基礎材に埋め込まれる領域のうち上端部から下端部に渡る上下方向幅を有してなることにより、固定金具による支柱の立設強度をより向上させることができる。   And according to the support | pillar foundation structure which concerns on this invention, the fixing bracket has the up-down direction width | variety ranging from an upper end part to a lower end part among the area | regions embedded in the concrete foundation material of a support | pillar, Therefore The standing strength can be further improved.

本発明の実施形態について、図面に沿って詳細に説明する。図1には本実施形態における支柱基礎構造の正面図を、図2には支柱基礎構造の横断面図を、それぞれ示している。これら各図においてコンクリート基礎材2は想像線で描かれている。図1に示すように、本実施形態における支柱基礎構造は、支柱1の下端部に固定金具3が取付けられ、固定金具3が取付けられた領域が埋設されるようにコンクリート基礎材2が打設されてなるものであり、かつ支柱1はコンクリート基礎材2の中央より一方側に偏芯配置されてなるものである。   Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a front view of a support foundation structure in the present embodiment, and FIG. 2 shows a cross-sectional view of the support foundation structure. In each of these drawings, the concrete base material 2 is drawn with imaginary lines. As shown in FIG. 1, in the support foundation structure in this embodiment, the concrete base material 2 is placed so that the fixing bracket 3 is attached to the lower end portion of the support 1 and the region where the fixing bracket 3 is attached is buried. The support column 1 is eccentrically arranged on one side from the center of the concrete base material 2.

図2に示すように、支柱1は断面略長方形状であって内部が中空状となるように形成されている。したがって、支柱1は四つの側面を有している。このうち支柱1がコンクリート基礎材2の中央に対して偏った側に面する側面を第1の面10とし、第1の面と対向する側面を第2の面11とする。固定金具3は二つの部品からなり、第1の面10と第2の面11を挟み込むように取付けられ連結されている。   As shown in FIG. 2, the support column 1 is formed so that the cross section is substantially rectangular and the inside is hollow. Therefore, the support column 1 has four side surfaces. Among these, a side surface facing the side where the support column 1 is biased with respect to the center of the concrete base material 2 is a first surface 10, and a side surface facing the first surface is a second surface 11. The fixture 3 is composed of two parts, and is attached and connected so as to sandwich the first surface 10 and the second surface 11.

固定金具3は、第1の面10側に取付けられる第1金具20と、第2の面11側に取付けられる第2金具21とが、締結具22により連結される。第1金具20は、支柱1の第1の面10及びこの第1の面10と直交する支柱1の側面12、12とを抱き込むようにして当接する凹部30と、凹部30の開口側端部から略直角方向に延びる平面部31とで、断面略ハット状となるように形成されている。一方、第2金具21は、支柱1の第2の面11に当接する当接面35と、この当接面から外方に延びて第1金具20の平面部31と対向する対向面36とを有し、これらが一枚の平板状となるように形成されている。   In the fixing bracket 3, a first bracket 20 attached to the first surface 10 side and a second bracket 21 attached to the second surface 11 side are connected by a fastener 22. The first metal fitting 20 includes a recess 30 that contacts the first surface 10 of the support column 1 and the side surfaces 12 and 12 of the support column 1 orthogonal to the first surface 10, and an opening side end of the recess 30. The flat portion 31 extending in a substantially right-angle direction is formed so as to have a substantially hat-shaped cross section. On the other hand, the second metal fitting 21 has a contact surface 35 that contacts the second surface 11 of the support column 1, and a facing surface 36 that extends outward from the contact surface and faces the flat portion 31 of the first metal fitting 20. These are formed so as to form a single flat plate.

第1金具20の凹部30は、支柱1の側面12の幅の約三分の一の深さを有するように形成されており、したがって、第1金具20の平面部31と第2金具21の対向面36は、支柱1の側面12の幅の半分以上の間隔を有して対向している。固定金具3が取付けられた支柱1の周囲にコンクリート基礎材2を打設することで、第1金具20の平面部31と第2金具21の対向面36の間にもコンクリートが充填される。   The concave portion 30 of the first metal fitting 20 is formed so as to have a depth of about one third of the width of the side surface 12 of the support column 1, and accordingly, the flat portion 31 of the first metal fitting 20 and the second metal fitting 21. The facing surfaces 36 are opposed to each other with an interval of at least half the width of the side surface 12 of the support column 1. By placing the concrete foundation material 2 around the support column 1 to which the fixing metal fitting 3 is attached, the concrete is also filled between the flat portion 31 of the first metal fitting 20 and the facing surface 36 of the second metal fitting 21.

このように支柱1の側面12から外方に向かって延出する金具間にコンクリートが充填されることで、支柱1の立設強度を高くすることができる。ここで、第1金具20は支柱1の第1の面10側を抱き込むように取付けられるので、固定金具3の支柱1に対する取付強度を大きくすることができ、かつ第1金具20の平面部31と第2金具21の対向面36との間隔が充分大きく確保されているので、支柱1の立設強度を大きくすることができる。   As described above, the concrete is filled between the metal fittings extending outward from the side surface 12 of the support column 1, whereby the standing strength of the support column 1 can be increased. Here, since the first metal fitting 20 is attached so as to embrace the first surface 10 side of the support post 1, the attachment strength of the fixing metal attachment 3 to the support post 1 can be increased, and the flat portion of the first metal attachment 20 is provided. Since the space | interval of 31 and the opposing surface 36 of the 2nd metal fitting 21 is ensured sufficiently large, the standing strength of the support | pillar 1 can be enlarged.

図3には、支柱1と固定金具3の分解横断面図を示している。この図に示すように、支柱1の第1の面10側から第1金具20を取付け、支柱1の第2の面11側から第2金具21を取付け、第1金具20はビス23により支柱1の第1の面10に対して固定する。第1金具20の平面部31と第2金具21の対向面36には、それぞれ挿通孔31a、36aが形成されており、これら挿通孔31a、36aに締結具22を構成するボルトを挿通し、反対側から締結具22を構成するナットにより締結固定する。これによって固定金具3は支柱1に対して固定される。   FIG. 3 shows an exploded cross-sectional view of the column 1 and the fixture 3. As shown in this figure, the first metal fitting 20 is attached from the first surface 10 side of the support column 1 and the second metal fitting 21 is attached from the second surface 11 side of the support column 1. The first surface 10 is fixed to the first surface 10. Insertion holes 31a and 36a are formed in the flat portion 31 of the first metal fitting 20 and the opposing surface 36 of the second metal fitting 21, respectively, and the bolts constituting the fastener 22 are inserted into the insertion holes 31a and 36a, Fastening is performed by a nut constituting the fastener 22 from the opposite side. As a result, the fixture 3 is fixed to the column 1.

また、図1に示すように、固定金具3は支柱1のコンクリート基礎材2に埋設される領域のうち上端部と下端部にそれぞれ設けられる。これによって、固定金具3が一つだけである場合よりも支柱1の立設強度をより大きくすることができる。   Further, as shown in FIG. 1, the fixing bracket 3 is provided at each of an upper end portion and a lower end portion in an area embedded in the concrete base material 2 of the column 1. Thereby, the standing strength of the column 1 can be further increased as compared with the case where there is only one fixture 3.

ここで、図1では固定金具3を二つ設けているものを示しているが、上下方向に幅広な固定金具3を一つ設けるようにしてもよい。図4には、別の例の固定金具3を有した支柱基礎構造の正面図を示している。この図に示すように、固定金具3を構成する第1金具20と第2金具21について、支柱1のコンクリート基礎材2に埋め込まれる領域のうち上端部から下端部に渡る上下方向幅を有するように形成することで、一対の固定金具によって充分な立設強度を確保することができる。   Here, FIG. 1 shows a case where two fixing brackets 3 are provided, but one fixing bracket 3 that is wide in the vertical direction may be provided. In FIG. 4, the front view of the support | pillar foundation structure which has the fixing metal fitting 3 of another example is shown. As shown in this figure, the first metal fitting 20 and the second metal fitting 21 constituting the fixing metal fitting 3 have a vertical width extending from the upper end portion to the lower end portion in the region embedded in the concrete base material 2 of the column 1. By forming in this way, a sufficient standing strength can be ensured by the pair of fixing brackets.

次に、本実施形態の支柱基礎構造を有した構造物の例として、カーポートについて説明する。図5にはカーポートの正面図を、図6にはカーポートの側面図を、それぞれ示している。これら各図に示すようにカーポートは、地面に立設される支柱1に梁42を片持ち状に設けてなる前フレーム材40と後フレーム材41とを前後方向に並設し、前フレーム材40と後フレーム材41の各梁42によって屋根体43を支持してなるものである。   Next, a carport will be described as an example of a structure having the support foundation structure of the present embodiment. FIG. 5 shows a front view of the carport, and FIG. 6 shows a side view of the carport. As shown in each of these figures, the carport has a front frame member 40 and a rear frame member 41, which are provided with a beam 42 in a cantilever manner on a column 1 that is erected on the ground. The roof body 43 is supported by the beams 42 of the material 40 and the rear frame material 41.

梁42は直線状に形成される一方、屋根体43は梁42の長手方向に沿って湾曲状に形成されており、屋根体43は両端部がそれぞれ梁42に支持されると共に、中間部は湾曲状に形成され梁42に載置される補助梁44によって支持される。   The beam 42 is formed in a straight line, while the roof body 43 is formed in a curved shape along the longitudinal direction of the beam 42. The roof body 43 is supported at both ends by the beam 42, and the intermediate portion is It is formed in a curved shape and is supported by an auxiliary beam 44 placed on the beam 42.

このカーポートにおいて、支柱1の下端部は本実施形態の支柱基礎構造を有しており、支柱1はコンクリート基礎材2の中央よりも梁42の延びる方向と反対側に偏って配置されている。支柱1の第1の面10はコンクリート基礎材2の中央に対して偏った側に面するように配置され、これに伴い支柱1の第2の面11は梁42の延びる方向に面するように配置される。   In this carport, the lower end portion of the support column 1 has the support column base structure of the present embodiment, and the support column 1 is arranged so as to be offset from the center of the concrete foundation material 2 on the side opposite to the extending direction of the beam 42. . The first surface 10 of the support column 1 is arranged so as to face the side that is biased with respect to the center of the concrete base material 2, and accordingly, the second surface 11 of the support column 1 faces the extending direction of the beam 42. Placed in.

支柱1は、屋根体43を支持する梁42の荷重を支えることとなるため、第2の面11側に倒れる方向に力が加わる。固定金具3の平面部31及び対向面36は、梁42の延びる方向に対して直交する方向に延びており、支柱1にかかる荷重を確実に受けることができる。したがって、支柱1の立設強度を適切に向上させることができる。   Since the column 1 supports the load of the beam 42 that supports the roof body 43, a force is applied in a direction in which the column 1 falls to the second surface 11 side. The flat portion 31 and the facing surface 36 of the fixture 3 extend in a direction orthogonal to the direction in which the beam 42 extends, and can reliably receive the load applied to the support column 1. Therefore, the standing strength of the column 1 can be appropriately improved.

また支柱1は、第1金具20を取付ける第1の面10と第2金具21を取付ける第2の面11とが反対であってもよい。すなわち、第1の面10が梁42の延びる方向に面するようにして、当該第1の面10に第1金具20を取付け、第1の面10と反対側の面を第2の面11として第2金具21を取付け、これらを締結具22で連結固定するようにしてもよい。ただし、図5のように配置した方が、コンクリート基礎材2の支柱1が偏った側の端面と平面部31または対向面36との距離が大きく取れるので、より強度を大きくすることができる。   Moreover, the 1st surface 10 which attaches the 1st metal fitting 20 and the 2nd surface 11 which attaches the 2nd metal fitting 21 may be opposite. That is, the first metal fitting 20 is attached to the first surface 10 so that the first surface 10 faces the direction in which the beam 42 extends, and the surface opposite to the first surface 10 is the second surface 11. As an alternative, the second metal fitting 21 may be attached, and these may be connected and fixed by the fastener 22. However, the arrangement as shown in FIG. 5 can increase the strength because the distance between the end surface of the concrete base material 2 on which the support column 1 is biased and the flat portion 31 or the opposed surface 36 can be increased.
