Description

本発明は例えば既存の対向する構造体間に後から鉄骨梁を架設する場合に、少なくとも一方の構造体がコンクリートである場合のように、鉄骨梁端部の構造体への接合のためにあと施工アンカーを使用せざるを得ない状況下において、構造体中に雌ねじアンカーを埋設することができない場合に、鉄骨梁の構造体への接合完了まで鉄骨梁を支持する鉄骨梁接合用仮支持部材、及びそれを使用した鉄骨梁の接合方法に関するものである。   The present invention, for example, in the case where a steel frame beam is to be installed later between existing opposing structures, as in the case where at least one structure is concrete, is used for joining the steel beam end to the structure. Temporary support member for steel beam joint which supports steel beam until completion of joining of steel beam to structure, when female screw anchor can not be embedded in the structure under the condition that construction anchor must be used And a method of joining steel beams using the same.

先行して構築、もしくは設置されているコンクリート造、もしくはコンクリート製の対向する壁間、または柱間等、対向するコンクリートの構造体間に、この構造体間距離に相当する長さを持つ鉄骨梁を架設するような場合、鉄骨梁はコンクリート部材間につっかい棒状に架設される。   Steel beam with a length equivalent to the distance between opposing concrete structures, such as between opposing concrete walls or columns made of concrete or concrete that have been constructed or installed in advance In the case of erecting a steel frame, the steel frame beam is erected in a stick shape between concrete members.

この関係で、鉄骨梁の端部に一体化し、コンクリート部材の表面に重なる端部プレートを厚さ方向に貫通するアンカーを用いて端部プレートをコンクリート部材に接合する場合に、コンクリート部材中に予め雌ねじアンカーを埋設しておくことができれば、端部プレートは雄ねじを形成したアンカー(ボルト)を雌ねじアンカーに螺入させることによりコンクリート部材に接合される(特許文献1参照)。   In this relationship, when joining an end plate to a concrete member using an anchor integrated with the end of the steel frame beam and penetrating the end plate overlapping the surface of the concrete member in the thickness direction, If the female screw anchor can be embedded, the end plate is joined to the concrete member by screwing an anchor (bolt) formed with a male screw into the female screw anchor (see Patent Document 1).

一方、鉄骨梁の架設後のコンクリート部材への接合時に、端部プレートをコンクリート部材に対して位置決めしながらコンクリート部材に接合する場合のように、コンクリート部材中に雌ねじアンカーを埋設しておくことが適切でない場合には、コンクリート部材には端部プレートを貫通するアンカーの位置に合わせてアンカー孔を穿設し、アンカー孔にアンカーを挿入するあと施工アンカーを使用せざるを得ない(特許文献2参照)。同じことは、端部プレートの接合のためのボルトの規模(径)の大きさに適合する雌ねじアンカーがない場合にも言える。   On the other hand, at the time of joining to a concrete member after erection of a steel frame beam, embedding an internal thread anchor in the concrete member as in the case of joining to a concrete member while positioning an end plate to the concrete member If it is not appropriate, the concrete member should be drilled with an anchor hole in accordance with the position of the anchor penetrating the end plate, and a post-construction anchor must be used to insert the anchor into the anchor hole (Patent Document 2) reference). The same is true if there is no internal threading anchor that fits the size (diameter) of the bolt for joining the end plates.

特開2008−7949号公報(段落0024〜0034、0047〜0050、図1、図7、図8)JP, 2008-7949, A (paragraphs 0024-0034, 0047-0050, FIG. 1, FIG. 7, FIG. 8) 特開2016−65428号公報(段落0027、図1、図4)JP, 2016-65428, A (paragraph 0027, FIG. 1, FIG. 4)

但し、鉄骨梁端部の端部プレートを貫通するボルトが挿入されるアンカー孔のコンクリート部材への穿設作業を、鉄骨梁を対向するコンクリート部材間に架設した状態で行う場合には、鉄骨梁の自重を負担しながら、架設状態を維持するためのサポートと作業用の足場を設置する必要があるため、両者を含めた支保工が大規模化し、施工が長期化することが想定される。   However, in the case where the drilling operation to the concrete member of the anchor hole into which the bolt penetrating the end plate of the steel beam end is inserted is carried out in a state in which the steel beam is bridged between the opposing concrete members Since it is necessary to install a support for maintaining the erection state and a work scaffold while bearing the weight of the support, it is expected that the support including both will be large scale and the construction will be prolonged.

また鉄骨梁は対向するコンクリート部材等の鉛直面をなす表面間に介在し、端部プレートとコンクリート部材表面間には鉄骨梁の軸方向に鉄骨梁を自由に移動できるだけの空間が確保されない状況に置かれ易いため、鉄骨梁をサポートが支持した状態での設置精度の確保も難しい。   In addition, steel beams are interposed between the vertical surfaces of opposing concrete members, etc., and space between the end plate and the surface of the concrete members can not be secured enough to freely move the steel beams in the axial direction of the steel beams. Since it is easy to place, it is also difficult to ensure the installation accuracy with the steel beam supported by the support.

本発明は上記背景より、簡素な構造(形状)でありながらコンクリート部材間等に架設された状態にある鉄骨梁を安全に支持可能な仮支持部材と、それを用いて鉄骨梁の設置精度を確保し得る鉄骨梁のコンクリート部材への接合方法を提案するものである。   From the above background, the present invention uses a temporary support member capable of safely supporting a steel frame beam in a state of being erected between concrete members while having a simple structure (shape), and using it, the installation accuracy of the steel frame beam We propose a method of joining steel beams to concrete members that can be secured.

請求項1に記載の発明の鉄骨梁接合用仮支持部材は、鉄骨梁の端部に一体化した端部プレートをコンクリート部材の表面に接合するまでの間、前記コンクリート部材に表面側から仮接合され、前記端部プレートを支持する仮設の仮支持部材であり、
前記コンクリート部材の表面に重なり、前記コンクリート部材中に仮固定される仮固定具が貫通する平板と、この平板の表面に一体化し、前記端部プレートに鉛直方向下向きと水平方向にそれぞれ係止する鉛直係止部と水平係止部を備え、この鉛直係止部と水平係止部とで区画された一部の領域が前記端部プレートが重なる受け部となり、
前記受け部に、前記端部プレートに形成された、または形成される定着具挿通孔に重なる仮接合具挿通孔が形成され、前記受け部以外の領域に、前記仮固定具が挿通する仮固定具挿通孔が形成されていることを構成要件とする。
The temporary support member for steel beam joint according to claim 1 is temporarily joined to the concrete member from the surface side until the end plate integrated with the end of the steel beam is joined to the surface of the concrete member. A temporary support member for supporting the end plate,
A flat plate which is superimposed on the surface of the concrete member and which a temporary fixing tool temporarily fixed in the concrete member penetrates is integrated with the surface of the flat plate, and is fixed to the end plate vertically downward and horizontally A vertical locking portion and a horizontal locking portion are provided, and a partial region defined by the vertical locking portion and the horizontal locking portion is a receiving portion in which the end plate overlaps.
A temporary bonding tool insertion hole is formed in the receiving portion, the temporary bonding tool insertion hole overlapping the fixing tool insertion hole formed or formed in the end plate, and the temporary fixing tool is inserted into a region other than the receiving portion. It is a component requirement that a tool insertion hole is formed.

鉄骨梁は表面が鉛直面等をなす柱、壁等の構造体の対向する表面間に架設され、軸方向の少なくとも一方の端部に端部プレートが一体化する。「端部プレートの一体化」は主に溶接による接合を言う。この鉄骨梁の少なくとも一方の端部に一体化した端部プレート側の構造体が鉄筋コンクリート造、またはプレキャストコンクリート製を含むコンクリート部材であり、端部プレートが一体化しない側の構造体は必ずしもコンクリート部材であるとは限らない。鉄骨梁7は少なくとも一方の端部に一体化する端部プレート8を含め、図1に示すように対向する構造体間に納まりながら、鉄骨梁7の軸方向に自由な移動が制約された状態で、対向する構造体間に架設され、双方に接合される。   The steel frame crosses between opposing surfaces of a structure having a vertical surface or the like, such as a column, a wall, etc., and the end plate is integrated with at least one end in the axial direction. "Integration of end plates" mainly refers to welding by welding. The structure on the end plate side integrated with at least one end of this steel frame beam is a concrete member including reinforced concrete or made of precast concrete, and the structure on the side where the end plate is not integrated is necessarily a concrete member Not necessarily. A condition in which the free movement of the steel frame beam 7 is restricted in the axial direction while the steel frame beam 7 is fitted between the opposing structures as shown in FIG. , And it is installed between opposing structures and joined to both.

仮支持部材1はコンクリート部材9が配置された側に配置され、そのコンクリート部材9には後述の仮固定具5により仮固定される。「コンクリート部材の表面」は主に鉛直面である。仮支持部材1はコンクリート部材9への端部プレート8の接合が完了し、その後の養生が済むまでコンクリート部材9に仮固定された状態を維持することで端部プレート8(鉄骨梁7)を支持し、養生後、回収される。   The temporary support member 1 is disposed on the side where the concrete member 9 is disposed, and is temporarily fixed to the concrete member 9 by a temporary fixing tool 5 described later. The "surface of the concrete member" is mainly a vertical surface. The temporary support member 1 completes the joining of the end plate 8 to the concrete member 9 and maintains the state of being temporarily fixed to the concrete member 9 until curing is completed, thereby the end plate 8 (steel beam 7) Support and recover after curing.

鉄骨梁7は先行して使用状態にある構造体間に架設されることから、端部プレート8が一体化した側のコンクリート部材9の表面には予め端部プレート8を受けるためのアンカー孔やボルト挿通孔が形成されていない。このため、コンクリート部材9には図2に示すように表面側から、端部プレート8をコンクリート部材9に接合するアンカー等の定着具10を定着させるための定着具定着孔9aを端部プレート8の接合前に形成することが必要になる。端部プレート8はコンクリート部材9への定着具定着孔9aの形成後にコンクリート部材9の表面側に配置される。図2では定着具定着孔9aと端部プレート8の関係を示すために、便宜的に端部プレート8付きの鉄骨梁7を示しているが、定着具定着孔9aの形成時には鉄骨梁7は架設されていない。鉄骨梁7は上記した仮支持部材1の仮固定後に架設され、仮支持部材1に支持される(図4、図5)。   Since the steel frame beam 7 is bridged between the structures in use in advance, an anchor hole for receiving the end plate 8 in advance is provided on the surface of the concrete member 9 on the side where the end plate 8 is integrated. The bolt insertion hole is not formed. For this reason, as shown in FIG. 2, the fixing member fixing hole 9 a for fixing the fixing tool 10 such as an anchor or the like for joining the end plate 8 to the concrete member 9 from the surface side is shown in FIG. It is necessary to form before joining. The end plate 8 is disposed on the surface side of the concrete member 9 after the formation of the fixing tool fixing holes 9 a in the concrete member 9. Although the steel frame beam 7 with the end plate 8 is shown for convenience in FIG. 2 in order to show the relationship between the fixing tool fixing hole 9a and the end plate 8, the steel frame beam 7 is formed when the fixing tool fixing hole 9a is formed. It is not erected. The steel frame beam 7 is constructed after the above-described temporary fixing of the temporary support member 1 and is supported by the temporary support member 1 (FIGS. 4 and 5).

一方、仮支持部材1は端部プレート8をコンクリート部材9への接合位置に位置決めしたまま、端部プレート8の接合完了まで支持し、コンクリート部材9表面の面内水平方向(鉄骨梁の幅方向)にも移動しないように保持する役目を果たすことが必要である。すなわち、仮支持部材1はコンクリート部材9への仮固定状態で、仮支持部材1の表面側に端部プレート8を配置し、端部プレート8を支持しながら、その面内水平方向にも端部プレート8を拘束できる形状である必要がある。   On the other hand, while the end plate 8 is positioned at the joining position to the concrete member 9, the temporary support member 1 supports the end plate 8 until joining is completed, and the in-plane horizontal direction of the surface of the concrete member 9 It also needs to play a role in keeping it from moving. That is, the temporary support member 1 arranges the end plate 8 on the surface side of the temporary support member 1 in the temporarily fixed state to the concrete member 9 and supports the end plate 8 and also ends in the in-plane horizontal direction. It needs to be in a shape that can restrain the partial plate 8.

この関係で、仮支持部材1は図4−(a)に示すようにコンクリート部材9の表面に重なるプレート等の平板2と、平板2の表面に一体化し、端部プレート8が鉛直方向下向きに係止する鉛直係止部3と、端部プレート8が平板2表面の面内水平方向に係止する水平係止部4を構成要素として備える。「鉛直係止部3等の一体化」は主に溶接による接合を言う。鉛直係止部3と水平係止部4は平板2の表面全体を端部プレート8が重なる領域である受け部21とそれ以外の領域に区画する。端部プレート8は受け部21の表面にその厚さ方向に重なる。   In this relationship, the temporary support member 1 is integrated with the flat plate 2 such as a plate overlapping the surface of the concrete member 9 as shown in FIG. 4A and the surface of the flat plate 2, and the end plate 8 is directed downward in the vertical direction. A vertical locking portion 3 for locking and a horizontal locking portion 4 for locking the end plate 8 in the in-plane horizontal direction of the surface of the flat plate 2 are provided as components. "Integration of the vertical locking portion 3 etc." mainly refers to welding by welding. The vertical locking portion 3 and the horizontal locking portion 4 divide the entire surface of the flat plate 2 into the receiving portion 21 in which the end plate 8 overlaps and the other region. The end plate 8 overlaps the surface of the receiving portion 21 in the thickness direction.

鉛直係止部3は端部プレート8(鉄骨梁7)の鉛直荷重を負担し、水平係止部4は端部プレート8の面内水平方向のいずれかの向きへの移動を拘束する。鉛直係止部3の、端部プレート8の係止面は実質的に水平面をなし、水平係止部4の係止面は実質的に鉛直面をなす。鉛直係止部3と水平係止部4は連続する場合と不連続の場合がある。   The vertical locking portion 3 bears the vertical load of the end plate 8 (the steel frame beam 7), and the horizontal locking portion 4 restrains the movement of the end plate 8 in any of the in-plane horizontal directions. The locking surface of the end plate 8 of the vertical locking portion 3 substantially constitutes a horizontal surface, and the locking surface of the horizontal locking portion 4 substantially constitutes a vertical surface. The vertical locking portion 3 and the horizontal locking portion 4 may be continuous or discontinuous.

1個(枚)の仮支持部材1の水平係止部4は面内水平方向のいずれかの向きへの、端部プレート8の移動を拘束するため、仮支持部材1は端部プレート8の面内水平方向のいずれの向きへの移動を拘束する上では、図4−(a)に示すように1枚の端部プレート8に付き、2個で対になって使用される。端部プレート8は対になる2個の仮支持部材1、1の平板2、2に跨りながら、コンクリート部材9の表面に対向させられる。端部プレート8はコンクリート部材9の表面に重なって仮固定された仮支持部材1(平板2)の受け部21の表面に重なるため、端部プレート8のコンクリート部材9側の背面とコンクリート部材9の表面との間には図4−(b)に示すように少なくとも仮支持部材1(平板2)の板厚分の空隙が確保される。図4は仮支持部材1と端部プレート8の関係を示すために、仮支持部材1に端部プレート8が支持された状況を示している。   In order to restrain the movement of the end plate 8 in any direction in the in-plane horizontal direction, the temporary support member 1 is formed of In order to constrain the movement in any direction in the in-plane horizontal direction, as shown in FIG. 4A, one end plate 8 is attached and used in pairs. The end plate 8 is made to face the surface of the concrete member 9 while straddling the flat plates 2 and 2 of the two temporary support members 1 and 1 forming a pair. Since the end plate 8 overlaps the surface of the receiving portion 21 of the temporary support member 1 (flat plate 2) which is superimposed and temporarily fixed on the surface of the concrete member 9, the back surface of the end plate 8 on the concrete member 9 side and the concrete member 9 As shown in FIG. 4-(b), an air gap of at least the thickness of the temporary support member 1 (flat plate 2) is secured between the surface of the temporary support member 1 and the surface of the support 2. FIG. 4 shows a state in which the end plate 8 is supported by the temporary support member 1 in order to show the relationship between the temporary support member 1 and the end plate 8.

端部プレート8は平板2の受け部21に重なり、端部プレート8の受け部21に重ならない領域がコンクリート部材9に接合されるまでの間、平板2に一時的に仮接合される。この端部プレート8の受け部21への仮接合のために、受け部21には図4−(a)に示すように端部プレート8を仮接合するボルト等の仮接合具6が挿通する仮接合具挿通孔2aが形成される。   The end plate 8 overlaps the receiving portion 21 of the flat plate 2 and is temporarily joined to the flat plate 2 temporarily until a region not overlapping the receiving portion 21 of the end plate 8 is joined to the concrete member 9. For temporary joining of the end plate 8 to the receiving portion 21, a temporary joining tool 6 such as a bolt for temporarily joining the end portion plate 8 is inserted into the receiving portion 21 as shown in FIG. The temporary bonding tool insertion hole 2a is formed.

仮接合具挿通孔2aに対応した端部プレート8の位置には、図3に示すように最終的に端部プレート8をコンクリート部材9に固定するアンカー等の定着具10が挿通するための定着具挿通孔8aが形成され、仮接合具6は図5に示すように定着具挿通孔8aと仮接合具挿通孔2aを挿通することにより端部プレート8を平板2に仮接合する(請求項4)。仮接合具6がボルトの場合、仮接合具6は仮接合具挿通孔2aに螺入する。定着具挿通孔8aには最終的に端部プレート8をコンクリート部材9に固定する定着具10が挿通するため、定着具挿通孔8aは平板2の仮接合具挿通孔2aの位置を含め、コンクリート部材9に穿設される後述の定着具定着孔9aに対応した位置に形成される。   Fixing for inserting a fixing tool 10 such as an anchor which finally fixes the end plate 8 to the concrete member 9 at the position of the end plate 8 corresponding to the temporary bonding tool insertion hole 2a as shown in FIG. 3 The tool insertion hole 8a is formed, and the temporary bonding tool 6 temporarily bonds the end plate 8 to the flat plate 2 by inserting the fixing tool insertion hole 8a and the temporary bonding tool insertion hole 2a as shown in FIG. 4). When the temporary joint 6 is a bolt, the temporary joint 6 is screwed into the temporary joint insertion hole 2a. Since the fixing tool 10 for finally fixing the end plate 8 to the concrete member 9 is inserted into the fixing tool insertion hole 8a, the fixing tool insertion hole 8a includes the position of the temporary bonding tool insertion hole 2a of the flat plate 2, concrete It is formed at a position corresponding to a fixing tool fixing hole 9a described later which is bored in the member 9.

平板2の受け部21以外の領域には、平板2が端部プレート8を支持し、鉄骨梁7の自重をコンクリート部材9に伝達するために、図4−(a)に示すように平板1をコンクリート部材9に仮固定するための仮設のアンカー等の仮固定具5が挿通する仮固定具挿通孔2bが形成される。図面では1枚の平板2に複数個の仮固定具挿通孔2bを形成しているが、仮固定具挿通孔2bの数は任意である。仮固定具挿通孔2bに対応した位置のコンクリート部材9にはボルト、またはアンカー等の仮固定具5が仮固定されるための仮固定具定着孔9bが穿設される。   In a region other than the receiving portion 21 of the flat plate 2, the flat plate 2 supports the end plate 8 and transmits the weight of the steel frame beam 7 to the concrete member 9 as shown in FIG. A temporary fixture insertion hole 2b is formed through which a temporary fixture 5 such as a temporary anchor for temporarily fixing the concrete to the concrete member 9 is inserted. Although several temporary fixing tool penetration holes 2b are formed in the flat plate 2 of 1 sheet in drawing, the number of temporary fixing tool penetration holes 2b is arbitrary. A temporary fixing tool fixing hole 9b for temporarily fixing a temporary fixing tool 5 such as a bolt or an anchor is bored in the concrete member 9 at a position corresponding to the temporary fixing tool insertion hole 2b.

コンクリート部材9にはまた、端部プレート8をコンクリート部材9に接合する定着具10が定着されるための上記した定着具定着孔9aも穿設される。定着具定着孔9aは端部プレート8に形成された、または形成される定着具挿通孔8aに対応した位置に形成されるが、具体的には定着具挿通孔8aは後述のように定着具定着孔9aの実際の穿設位置に合わせ、工場等で形成(穿設)される。仮固定具5は端部プレート8のコンクリート部材9への接合後には仮支持部材1(平板2)と共に回収されることから、仮固定具定着孔9bからの離脱を容易にするために、図面では図4〜図6に示すように仮固定具5にボルトを使用している。この場合、仮固定具定着孔9bには図示しないが、ボルトが螺入する雌ねじスリーブ(雌ねじアンカー)が挿入(埋設)される。   The above-described fixing tool fixing hole 9 a for fixing the fixing tool 10 for bonding the end plate 8 to the concrete member 9 is also bored in the concrete member 9. The fixing tool fixing hole 9a is formed at a position corresponding to the fixing tool insertion hole 8a formed or formed in the end plate 8. Specifically, the fixing tool insertion hole 8a is a fixing tool as described later. It is formed (pierced) in a factory or the like according to the actual drilling position of the fixing hole 9a. Since the temporary fixing tool 5 is recovered together with the temporary support member 1 (flat plate 2) after the end plate 8 is joined to the concrete member 9, the drawing for facilitating the detachment from the temporary fixing tool fixing hole 9b. Then, as shown in FIGS. 4 to 6, bolts are used for the temporary fixtures 5. In this case, although not shown, a female screw sleeve (female screw anchor) into which a bolt is screwed is inserted (embedded) into the temporary fixture fixing hole 9b.

仮支持部材1は平板2の仮固定具挿通孔2bを挿通する仮固定具5がコンクリート部材9の仮固定具定着孔9bに埋設等により定着されることによりコンクリート部材9に仮固定される。仮支持部材1はこの状態で図5−(a)に示すように平板2の鉛直係止部3上に端部プレート8が載置されることにより端部プレート8を支持する。仮支持部材1、1は前記のように2個で対になってコンクリート部材9に仮固定され、端部プレート8はこの2個の仮支持部材1、1の鉛直係止部3、3に支持される。端部プレート8は2個の仮支持部材1、1の平板2、2の水平係止部4、4に面内水平方向に係止することにより面内水平方向の移動に対して拘束される。   The temporary supporting member 1 is temporarily fixed to the concrete member 9 by fixing the temporary fixing tool 5 inserted through the temporary fixing tool insertion hole 2b of the flat plate 2 into the temporary fixing tool fixing hole 9b of the concrete member 9 by embedding or the like. In this state, the temporary support member 1 supports the end plate 8 by mounting the end plate 8 on the vertical locking portion 3 of the flat plate 2 as shown in FIG. The temporary supporting members 1, 1 are paired in pairs as described above and temporarily fixed to the concrete member 9, and the end plate 8 is attached to the vertical engaging portions 3, 3 of the two temporary supporting members 1, 1. Be supported. The end plate 8 is restrained against movement in the in-plane horizontal direction by locking in the in-plane horizontal direction to the horizontal engaging portions 4, 4 of the flat plates 2, 2 of the two temporary support members 1, 1 .

鉄骨梁7が対向する構造体間に架設された状態では前記のように鉄骨梁7が軸方向に移動できる距離が制限されているため、端部プレート8(鉄骨梁7)がコンクリート部材9の表面から遠ざかる向きに移動できる距離も制限されている。従って端部プレート8が平板2の鉛直係止部3上に載置されたときに、端部プレート8のコンクリート部材9から遠ざかる向きへの移動可能距離より大きい幅を鉛直係止部3が持てば、鉛直係止部3が端部プレート8を支持した状態で鉄骨梁7が軸方向に移動しても端部プレート8が鉛直係止部3から離脱する可能性はないため、鉛直係止部3は端部プレート8の鉛直荷重を安全に負担し、コンクリート部材9に伝達することができる。   In the state in which the steel frame beams 7 are bridged between the opposing structures, as described above, the distance by which the steel frame beams 7 can move in the axial direction is limited. The distance that can be moved away from the surface is also limited. Therefore, when the end plate 8 is placed on the vertical locking portion 3 of the flat plate 2, the vertical locking portion 3 has a width larger than the movable distance of the end plate 8 in the direction away from the concrete member 9. For example, even if the steel frame beam 7 moves in the axial direction with the vertical locking portion 3 supporting the end plate 8, there is no possibility that the end plate 8 may be detached from the vertical locking portion 3, so that vertical locking The part 3 can safely bear the vertical load of the end plate 8 and transmit it to the concrete member 9.

仮支持部材1は本体の平板2とその表面に一体化する鉛直係止部3及び水平係止部4から成立するため、簡素な構造(形状)でありながら、コンクリート部材9の表面に仮固定された状態を維持することで、端部プレート8のコンクリート部材9への接合完了まで、少なくとも一方がコンクリート部材9である構造体間に架設された状態にある鉄骨梁7を安全に支持する能力を有することになる。   Since the temporary support member 1 is formed of the vertical locking portion 3 and the horizontal locking portion 4 integrated with the flat plate 2 of the main body and its surface, the temporary support member 1 is temporarily fixed to the surface of the concrete member 9 while having a simple structure (shape). Ability to safely support the steel frame beam 7 in a state of being installed between the structures of which at least one is the concrete member 9 until the end plate 8 is joined to the concrete member 9 by maintaining the fixed state Will have.

同様に水平係止部4が端部プレート8のコンクリート部材9から遠ざかる向きへの移動可能距離より大きい幅を持てば、鉄骨梁7が軸方向に移動しても端部プレート8が水平係止部4から離脱することはないため、水平係止部4は端部プレート8の面内水平方向の移動を拘束することができる。   Similarly, if the horizontal locking portion 4 has a width greater than the movable distance of the end plate 8 in the direction away from the concrete member 9, the end plate 8 will be horizontal locked even if the steel frame beam 7 is moved in the axial direction. The horizontal locking portion 4 can restrain the in-plane horizontal movement of the end plate 8 since it does not leave the portion 4.

前記のように1枚の端部プレート8に付き、2個(枚)の仮支持部材1、1が使用されるため、2個の仮支持部材1、1が対になることで、端部プレート8の面内水平方向のいずれの向きにも移動を拘束することが可能である。結果として端部プレート8を鉛直係止部3が支持している状態での面内水平方向のずれが防止、または抑制されるため、端部プレート8を鉛直方向と面内水平方向(鉄骨梁7幅方向)に正確に位置決めした状態でコンクリート部材9に接合することが可能であり、端部プレート8の設置精度が向上する。   As described above, since two temporary supporting members 1 and 1 are used by attaching to one end plate 8, the two temporary supporting members 1 and 1 are paired to form an end. It is possible to constrain the movement in any direction in the in-plane horizontal direction of the plate 8. As a result, since the in-plane horizontal deviation in a state where the end plate 8 is supported by the vertical locking portion 3 is prevented or suppressed, the end plate 8 is vertically and horizontally in the in-plane direction (7) It is possible to join to the concrete member 9 in the state correctly positioned in (width direction), and the installation precision of the edge part plate 8 improves.

仮支持部材1を用いて端部プレート8をコンクリート部材9に接合する際には、図2に示すように端部プレート8をコンクリート部材9に接合する定着具10をコンクリート部材9に定着させるための定着具定着孔9aがコンクリート部材9に表面側から穿設される(請求項2)。定着具定着孔9aは端部プレート8に予め形成された、または後から形成される定着具挿通孔8aに対応した位置に穿設される。このとき、並行して仮支持部材1をコンクリート部材9に仮固定する仮固定具5を仮固定させるための仮固定具定着孔9bをコンクリート部材9に穿設すること、または上記のように穿設した仮固定具定着孔9bに仮固定具5を受ける雌ねじスリーブ(雌ねじアンカー)を埋設することも行われる。   When joining the end plate 8 to the concrete member 9 using the temporary support member 1, as shown in FIG. 2, the fixing tool 10 for joining the end plate 8 to the concrete member 9 is fixed to the concrete member 9 The fixing tool fixing hole 9a is formed in the concrete member 9 from the surface side (claim 2). The fixing tool fixing holes 9a are formed at positions corresponding to fixing tool insertion holes 8a which are formed in advance in the end plate 8 or are formed later. At this time, a temporary fixing tool fixing hole 9b for temporarily fixing the temporary fixing tool 5 for temporarily fixing the temporary support member 1 to the concrete member 9 in parallel is drilled in the concrete member 9 or drilled as described above It is also performed to embed a female screw sleeve (female screw anchor) for receiving the temporary fixing tool 5 in the temporary fixing tool fixing hole 9b.

「後から形成される定着具挿通孔8a」とは、コンクリート部材9に先行して穿設された定着具定着孔9aに合わせて端部プレート8に定着具挿通孔8aを形成することを言う(請求項3)。この場合、定着具定着孔9aに合わせて定着具挿通孔8aを形成することで、定着具挿通孔8aを予め形成しておく場合の施工誤差を軽減、あるいは解消することが可能になる。定着具定着孔9aに合わせて定着具挿通孔8aを形成することは、例えば穿設後の定着具定着孔9aの位置を正確に端部プレート8の背面に墨出し等の手段で転写(実測)し、その位置に従って定着具挿通孔8aを形成(穿設)することにより可能である。定着具挿通孔8aの形成は工場で、または現場付近で行われる。   The term “fixing tool insertion hole 8 a formed later” means that the fixing tool insertion hole 8 a is formed in the end plate 8 in accordance with the fixing tool fixing hole 9 a drilled in advance to the concrete member 9. (Claim 3). In this case, by forming the fixing tool insertion hole 8a in accordance with the fixing tool fixing hole 9a, it is possible to reduce or eliminate a construction error in the case where the fixing tool insertion hole 8a is formed in advance. Forming the fixing tool insertion hole 8a in accordance with the fixing tool fixing hole 9a is, for example, accurately transferring the position of the fixing tool fixing hole 9a after drilling on the back surface of the end plate 8 by means such as inking (measured And the fixing tool insertion hole 8a is formed (pierced) according to the position. The formation of the fixing tool insertion hole 8a is performed at the factory or near the site.

定着具定着孔9aをコンクリート部材9に穿設した後には(請求項2)、上記のように仮支持部材1が仮固定具5によりコンクリート部材9に仮固定され、仮支持部材1の鉛直係止部3と水平係止部4に端部プレート8が鉛直方向下向きと水平方向に係止させられる(請求項2)。端部プレート8が鉛直係止部3に係止させられることは、端部プレート8(鉄骨梁7)が鉛直係止部3に支持されることであり、水平係止部4に係止させられることは、対になる2個の仮支持部材1、1に端部プレート8が面内水平方向(鉄骨梁7の幅方向)に係止させられることを言い、端部プレート8(鉄骨梁7)が面内水平方向に拘束(保持)されることである。このとき、前記のように端部プレート8は仮支持部材1の平板2に一体化している鉛直係止部3と水平係止部4に係止することで、端部プレート8は鉛直方向と面内水平方向に位置決めされるため、端部プレート8は仮支持部材1、1に対して正確に設置される。   After the fixing tool fixing hole 9a is formed in the concrete member 9 (claim 2), the temporary support member 1 is temporarily fixed to the concrete member 9 by the temporary fixing tool 5 as described above. The end plate 8 is locked vertically downward and horizontally by the locking portion 3 and the horizontal locking portion 4 (claim 2). That the end plate 8 is locked to the vertical locking portion 3 is that the end plate 8 (the steel frame beam 7) is supported by the vertical locking portion 3 and locked to the horizontal locking portion 4 That is to say, the end plate 8 is locked in the in-plane horizontal direction (the width direction of the steel frame beam 7) to the two temporary support members 1 in a pair, and the end plate 8 (steel frame beam) 7) is to be constrained (held) in the in-plane horizontal direction. At this time, the end plate 8 is engaged with the vertical locking portion 3 and the horizontal locking portion 4 which are integrated with the flat plate 2 of the temporary support member 1 as described above. The end plate 8 is correctly installed with respect to the temporary support members 1, 1 in order to be positioned in the in-plane horizontal direction.

仮支持部材1に端部プレート8が係止させられた後、図5に示すように端部プレート8が平板2の受け部21に重ねられて仮接合される(請求項2)。この仮接合は前記のようにボルト等の仮接合具6を平板2の受け部21に重なる端部プレート8の定着具挿通孔8aと平板2の仮接合具挿通孔2aを挿通させることにより行われる(請求項4)。   After the end plate 8 is locked to the temporary support member 1, as shown in FIG. 5, the end plate 8 is superimposed on the receiving portion 21 of the flat plate 2 and is temporarily joined (claim 2). This temporary bonding is performed by inserting the fixing tool insertion hole 8a of the end plate 8 overlapping the temporary bonding tool 6 such as a bolt to the receiving portion 21 of the flat plate 2 and the temporary bonding tool insertion hole 2a of the flat plate 2 as described above. (Claim 4).

仮接合具6が端部プレート8の定着具挿通孔8aと平板2の仮接合具挿通孔2aを挿通し、端部プレート8を仮支持部材1の平板2に仮接合することで、図6に示すように平板2の受け部21に重ならない部分に形成されている定着具挿通孔8aからコンクリート部材9の定着具定着孔9aにまで定着具10を挿通させ、定着させることができる。   The temporary bonding tool 6 is inserted through the fixing tool insertion hole 8a of the end plate 8 and the temporary bonding tool insertion hole 2a of the flat plate 2, and the end plate 8 is temporarily bonded to the flat plate 2 of the temporary support member 1 as shown in FIG. The fixing tool 10 can be inserted and fixed from the fixing tool insertion hole 8a formed in a portion not overlapping the receiving portion 21 of the flat plate 2 to the fixing tool fixing hole 9a of the concrete member 9 as shown in FIG.

端部プレート8の平板2への仮接合後、端部プレート8の一部の定着具挿通孔8aを挿通し、アンカー等の定着具10がコンクリート部材9の定着具定着孔9aに埋設等により定着される(請求項2)。定着具10は端部プレート8の定着具挿通孔8aを挿通し、例えば定着具埋設孔9a内へのモルタル、接着剤等の充填等により定着具埋設孔9aに埋設されることにより定着される。「一部の定着具挿通孔8a」は端部プレート8が平板2の受け部21に重なる部分以外の部分に形成されている定着具挿通孔8aを指す。定着具10がコンクリート部材9に定着されることで、端部プレート8(鉄骨梁7)の鉛直荷重を定着具10を介してコンクリート部材9に負担させた状態にすることができる。   After temporary bonding of the end plate 8 to the flat plate 2, the fixing tool insertion hole 8a of a part of the end plate 8 is inserted, and the fixing tool 10 such as an anchor is embedded in the fixing tool fixing hole 9a of the concrete member 9 It is fixed (claim 2). The fixing tool 10 is inserted into the fixing tool insertion hole 8a of the end plate 8 and fixed by being embedded in the fixing tool embedding hole 9a by, for example, filling the fixing tool embedding hole 9a with mortar, an adhesive or the like. . The “part of fixing tool insertion holes 8 a” refers to the fixing tool insertion holes 8 a formed in a portion other than the portion where the end plate 8 overlaps the receiving portion 21 of the flat plate 2. By fixing the fixing tool 10 to the concrete member 9, the vertical load of the end plate 8 (the steel frame beam 7) can be borne by the concrete member 9 through the fixing tool 10.

図面では1枚の端部プレート8に付き、2本の仮接合具6で2個の仮支持部材1、1に仮接合し、4本の定着具10でコンクリート部材9に本接合しているが、仮接合用の仮接合具6の本数と本接合用の定着具10の本数は任意である。仮接合具6が挿通していた端部プレート8の定着具挿通孔8aには仮支持部材1、1の回収後、定着具10が挿通させられて定着具定着孔9aに定着させられ、端部プレート8の本接合に寄与する。   In the drawing, it is attached to one end plate 8 and is temporarily joined to two temporary supporting members 1 and 1 by two temporary joining tools 6 and is finally joined to a concrete member 9 by four fixing tools 10 However, the number of temporary bonding tools 6 for temporary bonding and the number of fixing tools 10 for main bonding are arbitrary. After recovering the temporary support members 1 and 1 through the fixing tool insertion holes 8a of the end plate 8 through which the temporary bonding tool 6 has been inserted, the fixing tool 10 is inserted and fixed in the fixing tool fixing holes 9a. It contributes to the main joining of the portion plate 8.

定着具10の定着具定着孔9aへの定着時、端部プレート8の一部を平板2に仮接合したまま、端部プレート8の他の一部をコンクリート部材9に本接合することができるため、端部プレート8を対になる2個の仮支持部材1、1のみに支持させたまま、端部プレート8をコンクリート部材9に接合することが可能になる。   At the time of fixing in the fixing tool fixing hole 9a of the fixing tool 10, another part of the end plate 8 can be permanently joined to the concrete member 9 while the end plate 8 is temporarily joined to the flat plate 2 Therefore, the end plate 8 can be joined to the concrete member 9 while the end plate 8 is supported only by the pair of temporary support members 1.

従って対になる2個の仮支持部材1、1のみが、端部プレート8のコンクリート部材9への仮支持から本接合までの間、端部プレート8(鉄骨梁7)を支持することができ、端部プレート8(鉄骨梁7)の仮支持のためのサポート、またはサポートと足場を含む支保工が不要になるため、端部プレート8のコンクリート部材9への接合のための仮設の設備が簡略化され、支保工の設置分の経費が節減され、時間が短縮される。   Therefore, only the two temporary support members 1 and 1 that are paired can support the end plate 8 (the steel frame beam 7) from the temporary support of the end plate 8 to the concrete member 9 to the main joining. , Temporary support for joining the end plate 8 to the concrete member 9 because there is no need for a support for temporary support of the end plate 8 (steel beam 7) or a support including a support and a scaffold It simplifies, saves the cost of installing the support and reduces the time.

定着具10の定着具定着孔9aへの定着後、仮支持部材1は回収され、端部プレート8の残りの定着具挿通孔8aを挿通して定着具10が定着具定着孔9aに埋設等により定着される(請求項2)。「残りの定着具挿通孔8a」は図6〜図8に示すように端部プレート8が平板2の受け部21に重なる部分に形成されている定着具挿通孔8aを指し、端部プレート8の仮支持部材1への仮接合時に両者を接合していた仮接合具6が挿通していた定着具挿通孔8aである。   After fixing the fixing tool 10 to the fixing tool fixing hole 9a, the temporary support member 1 is recovered, and the remaining fixing tool insertion hole 8a of the end plate 8 is inserted to embed the fixing tool 10 in the fixing tool fixing hole 9a It fixes by (Claim 2). The “remaining fixing tool insertion hole 8 a” refers to the fixing tool insertion hole 8 a formed in a portion where the end plate 8 overlaps the receiving portion 21 of the flat plate 2 as shown in FIGS. The fixing tool insertion hole 8a through which the temporary bonding tool 6 which was bonding both at the time of temporary bonding to the temporary support member 1 was inserted.

仮支持部材1の回収時には端部プレート8の定着具挿通孔8aを挿通し、端部プレート8を平板2に仮接合していた仮接合具6、及び仮支持部材1をコンクリート部材9に仮固定していた仮固定具5も回収される。仮接合具6の回収により開放した端部プレート8の(残りの)定着具挿通孔8aから定着具10が挿通させられ、定着具定着孔9aに埋設される等により定着される。端部プレート8の全定着具挿通孔8aから定着具10が定着具定着孔9aに定着されることで、端部プレート8のコンクリート部材9への接合が完了する。   At the time of recovery of the temporary support member 1, the fixing tool insertion hole 8 a of the end plate 8 is inserted, and the temporary joint tool 6 and the temporary support member 1 are temporarily attached to the concrete member 9. The temporary fixture 5 which has been fixed is also recovered. The fixing tool 10 is inserted through the (remaining) fixing tool insertion hole 8a of the end plate 8 opened by recovery of the temporary bonding tool 6, and is fixed by being embedded in the fixing tool fixing hole 9a or the like. The fixing tool 10 is fixed to the fixing tool fixing hole 9 a from the entire fixing tool insertion hole 8 a of the end plate 8, whereby the bonding of the end plate 8 to the concrete member 9 is completed.

請求項1ではコンクリート部材の表面に重なり、コンクリート部材中に仮固定される仮固定具が貫通する平板と、平板の表面に一体化し、端部プレートに鉛直方向下向きと水平方向にそれぞれ係止する鉛直係止部と水平係止部を備えるため、鉛直係止部において端部プレートの鉛直荷重を負担しながらコンクリート部材に伝達することができ、水平係止部において端部プレートの面内水平方向の移動を拘束することができる。特に端部プレートがコンクリート部材に対して移動可能な距離より大きい幅を鉛直係止部と水平係止部が持てば、鉛直係止部と水平係止部は端部プレートを離脱させることなく、端部プレートの鉛直荷重を安全に負担しながら面内水平方向の移動を拘束することができる。   In claim 1, the flat plate which is superimposed on the surface of the concrete member and temporarily fixed in the concrete member is integrated with the surface of the flat plate and the surface of the flat plate, and is fixed to the end plate vertically downward and horizontally Since the vertical locking portion and the horizontal locking portion are provided, the vertical locking portion can transmit the concrete member while carrying the vertical load of the end plate, and the horizontal locking portion in the in-plane horizontal direction of the end plate Can constrain the movement of In particular, if the vertical locking portion and the horizontal locking portion have a width greater than the movable distance of the end plate with respect to the concrete member, the vertical locking portion and the horizontal locking portion do not separate the end plate. The in-plane horizontal movement can be restrained while safely bearing the vertical load of the end plate.

結果として端部プレートを鉛直係止部が支持している状態での面内水平方向のずれが防止、または抑制されるため、端部プレートを鉛直方向と面内水平方向(鉄骨梁幅方向)に正確に位置決めした状態でコンクリート部材に接合することが可能になり、端部プレートの設置精度が向上する。   As a result, since the in-plane horizontal displacement is prevented or suppressed in a state where the end plate is supported by the vertical locking portion, the end plate is vertically and horizontally in-plane (steel beam width direction) It becomes possible to join to a concrete member in the state where it was correctly positioned, and the installation precision of an edge part plate improves.

また対になる2個の仮支持部材のみが、端部プレートのコンクリート部材への仮支持から本接合までの間、端部プレート(鉄骨梁)を支持することができることで、端部プレート(鉄骨梁)の仮支持のためのサポート、またはサポートと足場を含む支保工が不要になるため、端部プレートのコンクリート部材への接合のための仮設の設備が簡略化され、支保工の設置分の経費が節減され、時間が短縮される。   In addition, only the two temporary support members that are paired can support the end plate (steel frame beam) from the temporary support of the end plate to the concrete member to the main joining, so that the end plate (steel frame) The temporary installation for joining the end plate to the concrete member is simplified, since the support for temporary support of the beam or the support including the support and the scaffold is not required, and the installation of the support can be simplified. Save money and save time.

図1は軸方向の少なくとも一方の端部に端部プレート8が一体化した鉄骨梁7を、端部プレート8側がコンクリート部材9である、対向する構造体間に架設した状況を示す。対向する構造体の内、端部プレート8側の一方の構造体は鉄筋コンクリート造等のコンクリート部材9であり、他方はコンクリート部材、または鉄骨部材等である。コンクリート部材9を含め、構造体は表面が実質的に鉛直面をなす柱、または壁等である。   FIG. 1 shows a steel frame 7 in which an end plate 8 is integrated with at least one end in the axial direction and is bridged between opposing structures whose end plate 8 side is a concrete member 9. Among the opposing structures, one of the structures on the end plate 8 side is a concrete member 9 made of reinforced concrete or the like, and the other is a concrete member or a steel frame member or the like. The structure including the concrete member 9 is a pillar, a wall or the like whose surface is substantially vertical.

鉄骨梁7の他方側にも端部プレートが一体化することもあるが、鉄骨梁7の他方側の端部の、その側の構造体への接合方法は問われない。図1に示すように端部プレート8を含めた鉄骨梁7は対向する構造体間に納まりながら、鉄骨梁7の軸方向に自由な移動が制約された状態で、対向する構造体間に架設され、双方に接合される。図面では風荷重等、主に水平方向からの外力に抵抗させる目的で、強軸方向を水平方向に向けて鉄骨梁7を構造体間に架設しているが、鉄骨梁7の強軸方向(弱軸方向)の向きは任意である。   Although the end plate may be integrated on the other side of the steel frame beam 7, the method of joining the other end of the steel frame beam 7 to the structure on that side is not limited. As shown in FIG. 1, the steel frame beam 7 including the end plate 8 is placed between the opposing structures while the free movement in the axial direction of the steel beam 7 is restricted while being fitted between the opposing structures. And be joined to both. In the drawing, the steel frame beam 7 is bridged between the structures with the strong axial direction directed horizontally for the purpose of mainly resisting external force from horizontal direction such as wind load, but the strong axial direction of the steel frame beam 7 The direction of the weak axis direction is arbitrary.

鉄骨梁7の端部プレート8は図4に示すような、対になる2個の仮支持部材1、1に鉛直方向に支持されながら、端部プレート8の面内水平方向(鉄骨梁7の幅方向)に保持された状態でコンクリート部材9に接合される。仮支持部材1はコンクリート部材9の表面に重なり、コンクリート部材9中に仮固定される仮固定具5が貫通する平板2と、平板2の表面に一体化し、端部プレート8に鉛直方向下向きと水平方向にそれぞれ係止する鉛直係止部3と水平係止部4を構成要素として備える。   While the end plate 8 of the steel frame beam 7 is vertically supported by the pair of temporary support members 1 and 1 as shown in FIG. 4, the in-plane horizontal direction of the steel plate beam 7 It joins to the concrete member 9 in the state hold | maintained at width direction. The temporary supporting member 1 overlaps the surface of the concrete member 9 and is integrated with the flat plate 2 through which the temporary fixing tool 5 temporarily fixed in the concrete member 9 penetrates and the surface of the flat plate 2. A vertical locking portion 3 and a horizontal locking portion 4 that lock in the horizontal direction are provided as components.

平板2と鉛直係止部3及び水平係止部4にはこれに重なる端部プレート8に合わせ、主に形鋼等の鋼材が使用されるが、少なくともコンクリート部材9への仮固定時と端部プレート8の仮接合時に受ける、仮固定具5と仮接合具6による板厚方向の圧縮力を負担可能であれば、材料は問われず、硬質プラスチック等の使用も可能である。平板2の形状は必ずしも方形状である必要はない。図面では鉛直係止部3と水平係止部4に、端部プレート8側に平坦な面を形成可能な山形鋼を使用しているが、端部プレート8側にその位置決めが可能な面を持てば、形状は任意である。   The flat plate 2 and the vertical locking portion 3 and the horizontal locking portion 4 are mainly made of steel such as shaped steel according to the end plate 8 overlapping therewith, but at least when temporarily fixed to the concrete member 9 The material is not limited as long as the temporary fixing tool 5 and the temporary bonding tool 6 can bear the compressive force in the thickness direction received when the partial plate 8 is temporarily bonded, and hard plastic or the like can be used. The shape of the flat plate 2 does not have to be square. In the drawing, for the vertical locking portion 3 and the horizontal locking portion 4, a angle steel that can form a flat surface on the end plate 8 side is used, but a surface that can be positioned on the end plate 8 side If you have it, the shape is arbitrary.

平板2の全体の内、図4−(a)に示すように鉛直係止部3と水平係止部4とで区画された一部の領域が端部プレート8が厚さ方向に重なる受け部21となり、受け部21に、端部プレート8に形成された、または後から形成される定着具挿通孔8aに重なる仮接合具用挿通孔2aが形成され、受け部21以外の領域に、仮固定具5が挿通する仮固定具挿通孔2bが形成されている。仮接合具用挿通孔2aと仮固定具挿通孔2bは平板2を厚さ方向に貫通する。   Among the whole of the flat plate 2, as shown in FIG. 4A, a receiving portion in which the end plate 8 overlaps in the thickness direction with a partial region divided by the vertical locking portion 3 and the horizontal locking portion 4 21. A temporary joint tool insertion hole 2a is formed in the receiving portion 21 so as to overlap the fixing tool insertion hole 8a formed in the end plate 8 or later formed, and in a region other than the receiving portion 21 A temporary fixing tool insertion hole 2b through which the fixing tool 5 is inserted is formed. The temporary connector insertion hole 2a and the temporary fixture insertion hole 2b penetrate the flat plate 2 in the thickness direction.

受け部21を形成する一部の領域は端部プレート8が重なったときに、端部プレート8が受け部21から2方向に張り出すため、平板2の少なくとも一部の隅角部を含む領域になる。また受け部21には、図4−(a)に示すように端部プレート8が重なったときに、その重複領域に仮接合具6と定着具10が挿通する仮接合具挿通孔2aが形成可能な面積が確保される。この受け部21を区画するように鉛直係止部3と水平係止部4が平板2の表面から配置される。前記のように鉛直係止部3と水平係止部4に山形鋼を使用した場合には、平坦面が端部プレート8側を向くように配置される。仮固定具挿通孔2bは鉛直係止部3と水平係止部4が重ならない領域に形成される。   Since the end plate 8 projects from the receiving portion 21 in two directions when the end plates 8 overlap, a partial area forming the receiving portion 21 includes an area including at least a corner portion of the flat plate 2 become. Further, as shown in FIG. 4A, the receiving portion 21 is formed with a temporary bonding tool insertion hole 2a through which the temporary bonding tool 6 and the fixing tool 10 are inserted when the end plate 8 is overlapped. Possible area is secured. The vertical locking portion 3 and the horizontal locking portion 4 are disposed from the surface of the flat plate 2 so as to partition the receiving portion 21. When angle steel is used for the vertical locking portion 3 and the horizontal locking portion 4 as described above, the flat surface is disposed so as to face the end plate 8 side. The temporary fixing tool insertion hole 2b is formed in a region where the vertical locking portion 3 and the horizontal locking portion 4 do not overlap.

以下、図2〜図8に基づいて端部プレート8のコンクリート部材9への接合の手順を説明する。   Hereinafter, the procedure of joining to the concrete member 9 of the end plate 8 is demonstrated based on FIGS. 2-8.

図2に示すようにコンクリート部材9の表面の内、端部プレート8が重なったときの定着具挿通孔8aに対応した位置に定着具定着孔9aを、仮支持部材1が重なったときの平板2の仮固定具挿通孔2bに対応した位置に仮固定具定着孔9bをそれぞれドリル等により穿設する。   In the surface of the concrete member 9 as shown in FIG. 2, the fixing tool fixing hole 9a is located at a position corresponding to the fixing tool insertion hole 8a when the end plate 8 is overlapped, and a flat plate when the temporary support member 1 is overlapped. The temporary fixing tool fixing holes 9b are respectively drilled at positions corresponding to the temporary fixing tool insertion holes 2b of No. 2 using a drill or the like.

図2−(a)はコンクリート部材9の表面に端部プレート8を重ねた状況を想定した様子を示しているが、端部プレート8付きの鉄骨梁7はコンクリート部材9への定着具定着孔9aと仮固定具定着孔9bの穿設後(図4以降)に吊り込まれる。仮固定具定着孔9bに定着される仮固定具5は端部プレート8のコンクリート部材9への接合後、回収されるため、仮固定具5を回収可能にするために、仮固定具5にボルトが使用される場合を想定し、仮固定具定着孔9bには雌ねじの切られた雌ねじアンカーが埋設されることが適切である。   Fig. 2- (a) shows a state in which the end plate 8 is superimposed on the surface of the concrete member 9, but the steel frame beam 7 with the end plate 8 is a fixing tool fixing hole for the concrete member 9 After the holes 9a and the temporary fixing tool fixing holes 9b are bored (after FIG. 4), they are suspended. The temporary fixing tool 5 fixed to the temporary fixing tool fixing hole 9b is collected after the end plate 8 is joined to the concrete member 9, so that the temporary fixing tool 5 can be recovered by using the temporary fixing tool 5 Assuming that a bolt is used, it is appropriate that an internally threaded female screw anchor be embedded in the temporary fixture fixing hole 9b.

その後、図3に示すようにコンクリート部材9に穿設された定着具定着孔9aを、コンクリート部材9への接合位置に落とし込まれた端部プレート8、または落とし込まれたときの端部プレート8を想定した罫書き板等の背面、もしくは表面に墨出し、罫書き等の手段により転写し、その位置に定着具挿通孔8aをドリル等により穿設する。定着具挿通孔8aは端部プレート8の製作時に予め形成されることもある。   Thereafter, as shown in FIG. 3, the fixing plate fixing hole 9 a drilled in the concrete member 9 is dropped to the joining position to the concrete member 9, or the edge plate when dropped. 8 is performed on the back surface or surface of a scribing board or the like on the assumption of squeezing by scribing or other means, and a fixing tool insertion hole 8a is drilled at that position by a drill or the like. The fixing device insertion hole 8 a may be formed in advance when the end plate 8 is manufactured.

但し、現場でコンクリート部材9に穿設される定着具定着孔9aとの誤差の発生を抑制、または防止する上では、現場、もしくは工場で定着具定着孔9aの位置に合わせて定着具挿通孔8aを穿設することが合理的である。図面では鉄骨梁7の中心を通る鉛直線の片側に3個の定着具挿通孔8aを形成し、その内、最下段の定着具挿通孔8aを仮支持部材1への仮接合用に使用し、他の2個の定着具挿通孔8aをコンクリート部材9への本接合用に使用しているが、定着具挿通孔8aの形成数と配分は任意である。   However, in order to suppress or prevent the occurrence of an error with the fixing tool fixing hole 9a drilled in the concrete member 9 at the site, the fixing tool inserting hole is matched with the position of the fixing tool fixing hole 9a at the site or factory. It is reasonable to drill 8a. In the drawing, three fixing tool insertion holes 8a are formed on one side of a vertical line passing through the center of the steel frame beam 7, and the lowermost fixing tool insertion hole 8a is used for temporary bonding to the temporary support member 1 among them. Although the other two fixing tool insertion holes 8a are used for the main joining to the concrete member 9, the number and distribution of the fixing tool insertion holes 8a are arbitrary.

続いて図4に示すように仮固定具定着孔9bに仮固定具挿通孔2bを合致させて仮支持部材1の平板2をコンクリート部材9の表面に重ね、仮固定具挿通孔2bを貫通させて仮固定具5を仮固定具定着孔9bに挿入する。   Subsequently, as shown in FIG. 4, the temporary fixing tool insertion hole 2b is aligned with the temporary fixing tool fixing hole 9b, the flat plate 2 of the temporary support member 1 is overlapped on the surface of the concrete member 9, and the temporary fixing tool insertion hole 2b is penetrated. Then, the temporary fixing tool 5 is inserted into the temporary fixing tool fixing hole 9b.

端部プレート8のコンクリート部材9への接合終了後には図7に示すように仮固定具5は回収されるため、仮固定具5の仮固定具定着孔9bからの離脱作業性の面からは、仮固定具定着孔9bには雌ねじスリーブが挿入(埋設)されることが適切である。その場合、仮固定具5には雌ねじスリーブに螺入するボルトが使用される。但し、ボルト等の仮固定具5を直接、仮固定具定着孔9b内に挿入し、モルタル、接着剤等の充填材の充填により仮固定具定着孔9b内に埋設して定着させることもある。その場合、仮接合具(ボルト)5は頭部を切断することで、回収される。   After fixing of the end plate 8 to the concrete member 9 is completed, as shown in FIG. 7, the temporary fixing tool 5 is recovered, so from the aspect of separation workability from the temporary fixing tool fixing hole 9 b of the temporary fixing tool 5. It is appropriate that a female screw sleeve is inserted (embedded) in the temporary fixture fixing hole 9b. In that case, a bolt which is screwed into a female screw sleeve is used as the temporary fixture 5. However, the temporary fixing tool 5 such as a bolt may be directly inserted into the temporary fixing tool fixing hole 9b, and may be embedded and fixed in the temporary fixing tool fixing hole 9b by filling with a filler such as mortar or adhesive. . In that case, the temporary connector (bolt) 5 is recovered by cutting the head.

仮支持部材1、1は1枚の端部プレート8に付き、2個で対になって配置される。この2個の仮支持部材1、1における鉛直係止部3と水平係止部4、及び仮接合具挿通孔2aと仮固定具挿通孔2bは仮支持部材1、1間の中心線に関して対称な位置に配置される。仮支持部材1は図4−(b)に示すようにコンクリート部材9の表面に密着(接触)するように、または接近するように配置され、端部プレート8の配置時にはコンクリート部材9と端部プレート8の背面との間に挟み込まれる。   The temporary support members 1 are attached to one end plate 8 and arranged in pairs. The vertical locking portion 3 and the horizontal locking portion 4 in the two temporary support members 1 and 1 and the temporary bonding tool insertion hole 2 a and the temporary fixing tool insertion hole 2 b are symmetrical with respect to the center line between the temporary support members 1 and 1 Will be placed in The temporary support member 1 is disposed in close contact with (or in contact with) the surface of the concrete member 9 as shown in FIG. 4-(b), or when approaching the end plate 8, the concrete member 9 and the end portion It is sandwiched between the back of the plate 8 and the other.

仮固定具5が雌ねじスリーブへの接続等により仮固定具定着孔9b内に仮固定された後、図5に示すように2個の仮支持部材1、1の平板2、2の各受け部21に端部プレート8を重ね、合致した定着具挿通孔8aと仮接合具挿通孔2aにボルト等の仮接合具6を挿通させ、端部プレート8を平板2に仮接合する。仮接合具6がボルトの場合、仮接合具6は定着具挿通孔8aと仮接合具挿通孔2aに螺入する。図面では平板2の受け部21に重なった領域に形成されている端部プレート8の定着具挿通孔8aが1個の場合であるが、複数個の場合もある。   After the temporary fixing tool 5 is temporarily fixed in the temporary fixing tool fixing hole 9b by connection to a female screw sleeve or the like, as shown in FIG. 5, each receiving portion of the flat plates 2 and 2 of the two temporary support members 1 and 1 The end plate 8 is superimposed on the end plate 21 and the temporary joining tool 6 such as a bolt is inserted through the matched fixing tool insertion hole 8a and the temporary bonding tool insertion hole 2a, and the end plate 8 is temporarily joined to the flat plate 2. When the temporary bonding tool 6 is a bolt, the temporary bonding tool 6 is screwed into the fixing tool insertion hole 8a and the temporary bonding tool insertion hole 2a. In the drawing, the fixing tool insertion hole 8a of the end plate 8 formed in the area overlapping the receiving portion 21 of the flat plate 2 is one case, but there may be a plurality of fixing tool insertion holes.

受け部21に端部プレート8を重ねるとき、端部プレート8は2個の仮支持部材1、1の鉛直係止部3、3に載置されることにより仮支持部材1、1に支持され、水平係止部4、4に面内水平方向(鉄骨梁7幅方向)に係止することによりその方向の移動に対して拘束され、端部プレート8は2個の仮支持部材1、1に安定して支持され、保持される。   When the end plate 8 is superimposed on the receiving portion 21, the end plate 8 is supported by the temporary support members 1, 1 by being placed on the vertical locking portions 3, 3 of the two temporary support members 1, 1. By being locked to the horizontal locking portions 4 and 4 in the in-plane horizontal direction (the steel beam 7 width direction), the movement is restrained against movement in that direction, and the end plate 8 is fixed to two temporary supporting members 1 and 1 It is stably supported and held by

続いて図6に示すように端部プレート8の、平板2に重なっていない領域に形成されている定着具挿通孔8aを貫通させてアンカー等の定着具10をコンクリート部材9の定着具定着孔9aに挿入し、例えば充填材の充填により定着具10を定着具定着孔9a内に埋設する等により定着させる。定着具10の頭部は端部プレート8の表面から鉄骨梁7側へ突出する。定着具10の頭部には雄ねじが形成されており、この頭部にナット11が緊結されることにより端部プレート8がコンクリート部材9に接合される。定着具10の定着具定着孔9a内での定着の形態は問われず、定着具定着孔9a内への充填材の充填を伴わない形態の場合もある。   Subsequently, as shown in FIG. 6, the fixing tool insertion hole 8 a formed in the area not overlapping the flat plate 2 of the end plate 8 is penetrated to fix the fixing tool 10 such as an anchor to the fixing tool fixing hole of the concrete member 9. For example, the fixing tool 10 is fixed by being embedded in the fixing tool fixing hole 9a or the like by being filled with a filler. The head of the fixing tool 10 projects from the surface of the end plate 8 to the steel beam 7 side. An external thread is formed on the head of the fixing tool 10, and the end plate 8 is joined to the concrete member 9 by tightening a nut 11 on the head. The form of fixing in the fixing tool fixing hole 9a of the fixing tool 10 is not limited, and in some cases, there is a case without filling with the filler into the fixing tool fixing hole 9a.

定着具定着孔9aを挿通する定着具10は仮接合具6の回収(撤去)時に端部プレート8を定着具10のみで確実にコンクリート部材9に接合した状態を維持する必要があるため、平板2に重なっていない領域の定着具挿通孔8aは複数個、形成される。図面では端部プレート8を安定させてコンクリート部材9に接合するために、4個の定着具挿通孔8aを形成しているが、個数は任意である。   Fixing Tool The fixing tool 10 inserted through the fixing hole 9a is required to maintain a state in which the end plate 8 is reliably joined to the concrete member 9 only with the fixing tool 10 when the temporary bonding tool 6 is recovered (removed). A plurality of fixing tool insertion holes 8a in a region not overlapping 2 are formed. In the drawing, in order to stabilize the end plate 8 and join it to the concrete member 9, four fixing tool insertion holes 8a are formed, but the number is arbitrary.

端部プレート8のコンクリート部材9への接合後、図7に示すように仮接合具6が回収され、端部プレート8と仮支持部材1の仮接合状態が解除される。引き続き、仮固定具5が回収され、役目を終えた仮支持部材1も回収される。このとき、端部プレート8は平板2の受け部21に重なっていた領域以外の領域を挿通している定着具10のコンクリート部材9への定着によりコンクリート部材9への接合状態を維持している。   After the end plate 8 is joined to the concrete member 9, as shown in FIG. 7, the temporary joint 6 is recovered, and the temporary joint state of the end plate 8 and the temporary support member 1 is released. Subsequently, the temporary fixing tool 5 is recovered, and the temporary support member 1 which has finished its role is also recovered. At this time, the end plate 8 maintains the bonding state to the concrete member 9 by fixing the fixing tool 10 to the concrete member 9 which is inserted through the area other than the area overlapping the receiving portion 21 of the flat plate 2 .

その後、図8に示すように仮接合具6が挿通していた定着具挿通孔8aを貫通させてアンカー等の定着具10をコンクリート部材9の定着具定着孔9aに挿入し、充填材の充填等により定着具10を定着具定着孔9a内に埋設する等により定着させ、定着具10の頭部にナット11を緊結することにより端部プレート8がコンクリート部材9に完全に接合される。端部プレート8は最終的には端部プレート8に形成されている定着具挿通孔8aの数分の本数の定着具10によってコンクリート部材9に接合される。   Thereafter, as shown in FIG. 8, the fixing tool insertion hole 8a through which the temporary bonding tool 6 has been inserted is penetrated, and the fixing tool 10 such as an anchor is inserted into the fixing tool fixing hole 9a of the concrete member 9, and the filling material is filled. The fixing tool 10 is fixed by being embedded in the fixing tool fixing hole 9a or the like, and the end plate 8 is completely joined to the concrete member 9 by tightening the nut 11 on the head of the fixing tool 10. The end plate 8 is finally joined to the concrete member 9 by the number of fixing tools 10 which is equal to the number of fixing tool insertion holes 8 a formed in the end plate 8.
