Description

本発明は、位置決め部材および建方方法に関する。詳しくは、鉄骨部材の鉄筋コンクリート部材に対する高さを決定する位置決め部材、および、この位置決め部材を用いた建方方法に関する。   The present invention relates to a positioning member and a building method. Specifically, the present invention relates to a positioning member that determines the height of a steel frame member relative to a reinforced concrete member, and a building method using the positioning member.

従来より、柱を鉄筋コンクリート造とし、梁を鉄骨梁とする複合柱梁架構の建物が知られている（特許文献１参照）。
このような建物の施工では、鉄筋コンクリート柱を構築し、この鉄筋コンクリート柱の柱頭部に鉄骨梁を据え付けるが、このとき、鉄骨梁の高さ位置を精度よく管理することが重要である。 2. Description of the Related Art Conventionally, a composite column beam building in which a column is a reinforced concrete structure and a beam is a steel beam is known (see Patent Document 1).
In the construction of such a building, a reinforced concrete column is constructed and a steel beam is installed on the column head of this reinforced concrete column. At this time, it is important to accurately manage the height position of the steel beam.

そこで、例えば、受け金物を用いて鉄骨梁の高さ位置を管理することが考えられる。
受け金物は、例えば、型枠に取り付けた型枠連結ボルトと、このボルトに支持されて柱ベース芯が予め穿孔されたプレートと、を備える（特許文献１参照）。 In view of this, for example, it is conceivable to manage the height position of the steel beam using a hardware.
The receiving hardware includes, for example, a formwork connection bolt attached to the formwork, and a plate that is supported by this bolt and in which a column base core is previously perforated (see Patent Document 1).

この受け金物に設置方法は、例えば以下のようになる。
まず、柱筋を配筋し、その後、この柱筋を囲んで柱型枠を建て込む。次に、この型枠に鉄骨梁の受け金物の型枠連結ボルトを取り付けて、この型枠連結ボルトにプレートを取り付ける。その後、柱型枠内にコンクリートを打設し、この受け金物の上に鉄骨梁を載せる。
あるいは、コンクリートを打設した直後に、受け金物をコンクリートに埋め込む。 For example, the installation method for the hardware is as follows.
First, a column is arranged, and then a column mold is built around the column. Next, the formwork connection bolt of the steel beam receiving metal is attached to the formwork, and the plate is attached to the formwork connection bolt. After that, concrete is placed in the column formwork, and a steel beam is placed on the receiving metal.
Alternatively, immediately after placing the concrete, the metal fitting is embedded in the concrete.

特許第５０７７８５６号公報Japanese Patent No. 50777856

しかしながら、上述の受け金物を複合柱梁架構の構築に適用しようとすると、以下のような問題がある。
すなわち、鉄筋コンクリート柱のコンクリート打設時には、この柱型枠の内部にコンクリートホースを挿入してコンクリートを打設する。しかし、上述の受け金物のプレートは、鉄筋コンクリート柱の略中心に配置されるので、このプレートがコンクリートホースに干渉して、コンクリート打設作業を円滑に実施できないおそれがあった。 However, if the above-mentioned metal fitting is applied to the construction of a composite column beam structure, there are the following problems.
That is, at the time of concrete placement of a reinforced concrete pillar, concrete is placed by inserting a concrete hose into the inside of the pillar formwork. However, since the plate of the above-described metal receiving member is disposed at the approximate center of the reinforced concrete column, the plate may interfere with the concrete hose and the concrete placing operation may not be smoothly performed.

また、受け金物の型枠連結ボルトを柱型枠に取り付けると、この型枠連結ボルトが柱筋に干渉してしまい、実際には、受け金物を柱型枠に取り付けることは困難であった。   Further, when the formwork connecting bolts of the receiving metal are attached to the column formwork, the formwork connecting bolts interfere with the column lines, and it was actually difficult to attach the receiving metal to the column formwork.

また、コンクリートを打設した直後に受け金物をコンクリートに埋め込んだ場合には、コンクリートの締まり具合によっては受け金物が沈み込んでレベルが下がったり、受け金物が傾いたりするおそれがあった。   In addition, when the received metal is embedded in the concrete immediately after placing the concrete, the received metal may sink and the level may be lowered or the received metal may be tilted depending on the degree of concrete tightening.

本発明は、コンクリート打設作業を円滑に行うことができ、かつ、鉄骨梁の高さを高精度で位置決めできる位置決め部材および建方方法を提供することを目的とする。   An object of the present invention is to provide a positioning member and a building method that can smoothly perform concrete placing work and can position the height of a steel beam with high accuracy.

請求項１および２に記載の位置決め部材（例えば、後述の位置決め部材１０）は、鉄筋コンクリート部材（例えば、後述の下階柱２０Ａ）に鉄骨部材（例えば、後述の鉄骨梁３０）が接合される複合架構（例えば、後述の複合柱梁架構１）について、当該鉄骨部材の前記鉄筋コンクリート部材に対する高さを決定する位置決め部材であって、前記鉄骨部材が載置されるボルト（例えば、後述のボルト１１）と、当該ボルトが螺合されるナット（例えば、後述の高ナット１２）と、当該ナットに設けられて前記鉄筋コンクリート部材の鉄筋（例えば、後述のフープ筋２４）に取り付けられる支持部材（例えば、後述の支持部材１３）と、を備えることを特徴とする。 Positioning member according to claim 1 and 2 (e.g., the positioning member 10 described later), the composite of reinforced concrete member (e.g., lower Kaibashira 20A described later) to the steel member (e.g., steel beams 30 to be described later) is bonded A positioning member that determines the height of the steel member relative to the reinforced concrete member for a frame (for example, a composite column beam frame 1 described later), and a bolt (for example, a bolt 11 described later) on which the steel member is placed And a nut (for example, a high nut 12 described later) to which the bolt is screwed, and a support member (for example, described later) provided on the nut and attached to a reinforcing bar (for example, a hoop bar 24 described later) of the reinforced concrete member. A support member 13).

ここで、鉄骨部材としては、鉄骨梁や鉄骨柱が挙げられる。
また、鉄筋コンクリート部材としては、鉄筋コンクリート柱が挙げられる。 Here, examples of the steel member include a steel beam and a steel column.
Moreover, a reinforced concrete pillar is mentioned as a reinforced concrete member.

この発明によれば、位置決め部材を、ボルト、ナット、および支持部材を含んで構成し、さらに、支持部材を鉄筋コンクリート部材の鉄筋に取り付けた。
したがって、位置決め部材を確実に固定できる。また、位置決め部材が鉄筋の近傍に配置されるので、この位置決め部材はコンクリート打設時にコンクリートホースに干渉しないから、コンクリート打設作業を円滑に行うことができる。 According to the present invention, the positioning member includes the bolt, the nut, and the support member, and the support member is attached to the reinforcing bar of the reinforced concrete member.
Therefore, the positioning member can be reliably fixed. In addition, since the positioning member is disposed in the vicinity of the reinforcing bar, the positioning member does not interfere with the concrete hose when the concrete is placed, so that the concrete placing operation can be performed smoothly.

また、コンクリートを打設した後、位置決め部材のボルトを回して、このボルトのナットからの突出寸法を調整することで、鉄骨部材を高精度で位置決めできる。   Further, after placing the concrete, the steel member can be positioned with high accuracy by turning the bolt of the positioning member and adjusting the projecting dimension of the bolt from the nut.

請求項２に記載の位置決め部材は、前記鉄筋コンクリート部材は、鉄筋コンクリート柱であり、前記ボルトは、当該鉄筋コンクリート柱の柱主筋位置よりも柱中心寄りに配置されることを特徴とする。   The positioning member according to claim 2 is characterized in that the reinforced concrete member is a reinforced concrete column, and the bolt is arranged closer to the center of the column than a column main reinforcing bar position of the reinforced concrete column.

この発明によれば、位置決め部材のボルトを、鉄筋コンクリート柱の柱主筋位置よりも柱中心寄りに配置したので、鉄骨部材の荷重が偏心荷重として鉄筋コンクリート柱に作用するのを抑制できる。
また、ボルトで支持された鉄骨部材の重量が鉄筋コンクリート柱の柱主筋で囲まれた部分に加わるようにすることで、偏心軸力の影響で鉄筋コンクリート柱の外縁部に生じるコンクリートの損傷やひびわれの発生を防止できる。 According to this invention, since the bolt of the positioning member is disposed closer to the center of the column than the position of the column main reinforcement of the reinforced concrete column, it is possible to suppress the load of the steel member from acting on the reinforced concrete column as an eccentric load.
In addition, by causing the weight of the steel members supported by bolts to be added to the part surrounded by the column main reinforcement of the reinforced concrete column, damage to the concrete and the occurrence of cracks at the outer edge of the reinforced concrete column due to the eccentric axial force Can be prevented.

請求項３に記載の位置決め部材は、前記ナットの上端面は、コンクリート打設面（例えば、後述のコンクリート打設面Ｃ）から露出することを特徴とする。   The positioning member according to claim 3 is characterized in that an upper end surface of the nut is exposed from a concrete placement surface (for example, a concrete placement surface C described later).

この発明によれば、ナットの上端面をコンクリート打設面から露出させることで、コンクリートの打設後に、ボルトを自在に回して、ボルトのナットからの突出寸法を調整することで、鉄骨部材を所定の高さに位置決めできる。   According to this invention, by exposing the upper end surface of the nut from the concrete placement surface, the bolt can be freely rotated after placing the concrete, and the projecting dimension of the bolt from the nut can be adjusted to It can be positioned at a predetermined height.

請求項４に記載の建方方法は、鉄筋コンクリート部材に鉄骨部材が接合される複合架構について、当該鉄骨部材の建方を行う建方方法であって、前記鉄骨部材が載置されるボルトと、当該ボルトが螺合されるナットと、当該ナットに設けられて前記鉄筋コンクリート部材の鉄筋に取り付けられる支持部材と、を備える位置決め部材を用意し、鉄筋コンクリート部材の鉄筋を配筋し、型枠を建て込む工程（例えば、後述のステップＳ１）と、前記鉄筋に位置決め部材を取り付ける工程（例えば、後述のステップＳ２）と、前記型枠内にコンクリートを打設する工程（例えば、後述のステップＳ３）と、前記ボルトの上に前記鉄骨部材を載せる工程（例えば、後述のステップＳ５）と、を備えることを特徴とする。
なお、前記鉄筋に位置決め部材を取り付ける工程では、前記ボルトを前記鉄筋コンクリート部材の主筋位置よりも部材中心寄りに配置する。 The construction method according to claim 4 is a construction method for constructing a steel frame member for a composite frame in which a steel member is joined to a reinforced concrete member, and a bolt on which the steel member is placed; A positioning member comprising a nut to which the bolt is screwed and a support member provided on the nut and attached to the reinforcing bar of the reinforced concrete member is prepared, the reinforcing bar of the reinforced concrete member is arranged, and the formwork is built A step (for example, step S1 described later), a step for attaching a positioning member to the reinforcing bar (for example, step S2 described later), a step for placing concrete in the mold (for example, step S3 described later), And a step of placing the steel member on the bolt (for example, step S5 described later).
In the step of attaching the positioning member to the reinforcing bar, the bolt is arranged closer to the member center than the main reinforcing bar position of the reinforced concrete member.

この発明によれば、上述の請求項１と同様の効果がある。   According to the present invention, there is an effect similar to that of the first aspect.

本発明によれば、位置決め部材を、ボルト、ナット、および支持部材を含んで構成し、さらに、支持部材を鉄筋コンクリート部材の鉄筋に取り付けた。したがって、位置決め部材を確実に固定できる。また、位置決め部材が鉄筋の近傍に配置されるので、この位置決め部材はコンクリート打設時にコンクリートホースに干渉しないから、コンクリート打設作業を円滑に行うことができる。また、コンクリートを打設した後、位置決め部材のボルトを回して、このボルトのナットからの突出寸法を調整することで、鉄骨部材を高精度で位置決めできる。   According to the present invention, the positioning member includes a bolt, a nut, and a support member, and the support member is attached to the reinforcing bar of the reinforced concrete member. Therefore, the positioning member can be reliably fixed. In addition, since the positioning member is disposed in the vicinity of the reinforcing bar, the positioning member does not interfere with the concrete hose when the concrete is placed, so that the concrete placing operation can be performed smoothly.

以下、下階柱２０Ａに鉄骨梁３０を取り付ける手順について、図４のフローチャートを参照しながら説明する。
まず、ステップＳ１では、図５に示すように、下階柱２０Ａの柱筋２２を配筋し、この柱筋２２を囲んで柱型枠２５を建て込む。 Hereinafter, the procedure for attaching the steel beam 30 to the lower floor pillar 20A will be described with reference to the flowchart of FIG.
First, in step S1, as shown in FIG. 5, the column reinforcement 22 of the lower floor pillar 20A is arranged, and the column form frame 25 is built around the column reinforcement 22.

ステップＳ２では、図５に示すように、柱筋２２の４箇所に位置決め部材１０を取り付ける。具体的には、ひげ筋１５を柱筋２２のフープ筋２４になまし線で結束固定することで、各位置決め部材１０を柱筋２２に取り付ける。
ステップＳ３では、図５に示すように、柱型枠２５内に図５中破線Ｃの高さまでコンクリートを打設する。これにより、高ナット１２の上端面がこのコンクリート打設面Ｃから露出する。 In step S2, as shown in FIG. 5, the positioning members 10 are attached to the four locations of the column 22. Specifically, the positioning members 10 are attached to the columnar bars 22 by binding and fixing the beard muscles 15 to the hoop lines 24 of the columnar bars 22 with an annealing line.
In step S3, as shown in FIG. 5, concrete is poured into the column mold 25 to the height of the broken line C in FIG. Thereby, the upper end surface of the high nut 12 is exposed from the concrete placing surface C.

ステップＳ４では、図６に示すように、柱型枠２５を解体し、位置決め部材１０の高さ寸法を調整する。具体的には、各位置決め部材１０のボルト１１を回して、ボルト１１の高ナット１２からの突出寸法を調整し、ボルト１１の高さを所定の高さで揃える。
ステップＳ５では、図６に示すように、鉄骨梁３０を取り付ける。具体的には、位置決め部材１０のボルト１１の上に、鉄骨梁３０の下フランジ３１を載せる。 In step S4, as shown in FIG. 6, the column form frame 25 is disassembled and the height dimension of the positioning member 10 is adjusted. Specifically, the bolt 11 of each positioning member 10 is turned to adjust the projecting dimension of the bolt 11 from the high nut 12, and the height of the bolt 11 is aligned at a predetermined height.
In step S5, the steel beam 30 is attached as shown in FIG. Specifically, the lower flange 31 of the steel beam 30 is placed on the bolt 11 of the positioning member 10.

本実施形態によれば、以下のような効果がある。
（１）位置決め部材１０を、ボルト１１、高ナット１２、および支持部材１３を含んで構成し、さらに、支持部材１３の２本のひげ筋１５を下階柱２０Ａのフープ筋２４に取り付けた。
したがって、位置決め部材１０を確実に固定できる。また、位置決め部材１０が柱筋２２の近傍に配置されるので、この位置決め部材１０はコンクリート打設時にコンクリートホースに干渉しないから、コンクリート打設作業を円滑に行うことができる。 According to this embodiment, there are the following effects.
(1) The positioning member 10 includes a bolt 11, a high nut 12, and a support member 13, and two scissors 15 of the support member 13 are attached to the hoop bars 24 of the lower floor pillar 20 </ b> A.
Therefore, the positioning member 10 can be reliably fixed. Further, since the positioning member 10 is disposed in the vicinity of the column bar 22, the positioning member 10 does not interfere with the concrete hose when the concrete is placed, so that the concrete placing operation can be performed smoothly.

また、コンクリートを打設した後、位置決め部材１０のボルト１１を回して、このボルト１１の高ナット１２からの突出寸法を調整することで、鉄骨梁３０を高精度で位置決めできる。   Moreover, after placing concrete, the steel beam 30 can be positioned with high precision by turning the bolt 11 of the positioning member 10 and adjusting the projecting dimension of the bolt 11 from the high nut 12.

また、高ナット１２の下端に溶接固定されたプレート１４に２本のひげ筋１５を取り付けることで、コンクリートを打設する前に、鉄骨梁３０を設置する所定高さにボルト１１を設置できる。   Moreover, the bolt 11 can be installed in the predetermined height which installs the steel beam 30 before placing concrete, by attaching the two barb muscles 15 to the plate 14 weld-fixed to the lower end of the high nut 12.

（２）位置決め部材１０のボルト１１を、下階柱２０Ａの柱主筋２３の位置よりも柱中心寄りに配置したので、鉄骨梁３０の荷重が偏心荷重として下階柱２０Ａに作用するのを抑制できる。
また、ボルト１１で支持された鉄骨梁３０の重量が下階柱２０Ａの柱主筋２３で囲まれた部分に加わるようにすることで、偏心軸力の影響で下階柱２０Ａの外縁部に生じるコンクリートの損傷やひびわれの発生を防止できる。 (2) Since the bolt 11 of the positioning member 10 is arranged closer to the center of the column than the position of the column main reinforcement 23 of the lower floor column 20A, the load of the steel beam 30 is prevented from acting on the lower column 20A as an eccentric load. it can.
In addition, the weight of the steel beam 30 supported by the bolt 11 is added to the portion surrounded by the column main reinforcement 23 of the lower floor column 20A, so that it is generated at the outer edge of the lower column 20A due to the influence of the eccentric axial force. It can prevent concrete damage and cracking.

（３）高ナット１２の上端面をコンクリート打設面Ｃから露出させることで、コンクリートの打設後に、ボルト１１を自在に回して、ボルト１１の高ナット１２からの突出寸法を調整することで、鉄骨梁３０を所定の高さに位置決めできる。   (3) By exposing the upper end surface of the high nut 12 from the concrete placing surface C, the bolt 11 can be freely rotated after the concrete is placed, and the projecting dimension of the bolt 11 from the high nut 12 is adjusted. The steel beam 30 can be positioned at a predetermined height.
