Description

本発明は、接合構造及び接合方法に関し、特に、隣接する鉄筋コンクリート部材(柱、梁等のPC部材)間の接合に有効な接合構造及び接合方法に関する。   The present invention relates to a joining structure and a joining method, and more particularly to a joining structure and a joining method effective for joining between adjacent reinforced concrete members (PC members such as columns and beams).
近年、鉄筋コンクリート構造物の施工の高品質化、工期短縮等を図るため、プレキャストコンクリート(以下、PCという。)柱や梁等のPC部材が広く用いられている。PC柱や梁等のPC部材を用いて鉄筋コンクリート構造物を架構する場合、隣接するPC部材間の接合に各種の接合方法が利用されている。その一例を図10及び図11に示す。   In recent years, PC members such as precast concrete (hereinafter referred to as PC) columns and beams have been widely used in order to improve the quality of construction of reinforced concrete structures and shorten the construction period. When a reinforced concrete structure is constructed using PC members such as PC pillars and beams, various joining methods are used for joining between adjacent PC members. An example thereof is shown in FIGS.
すなわち、図10及び図11に示す接合方法は、隣接する一対のPC梁部材50、60間の接合方法であって、図10に示すように、予め、各PC梁部材50、60の接合端面56、66から主筋52、62をそれぞれ所定の長さ突出させ、その突出させた部分を所定の位置から所定の角度で屈曲させておく。そして、両PC梁部材50、60を所定の位置に位置決めし、両PC梁部材50、60の接合端面56、66同士を所定の間隔をおいて対向させ、各接合端面56、66から突出している主筋52、62を互いに重ね合わせる。そして、図11に示すように、両PC梁部材50、60の接合端面56、66間にコンクリートを打設する。
このようにして、隣接する一対のPC梁部材50、60間を一体に接合することができる。
That is, the joining method shown in FIG. 10 and FIG. 11 is a joining method between a pair of adjacent PC beam members 50 and 60, and as shown in FIG. The main muscles 52 and 62 protrude from the 56 and 66 by a predetermined length, respectively, and the protruding portions are bent at a predetermined angle from a predetermined position. Then, the PC beam members 50 and 60 are positioned at predetermined positions, the joint end surfaces 56 and 66 of the PC beam members 50 and 60 are opposed to each other at a predetermined interval, and protrude from the joint end surfaces 56 and 66. The main muscles 52 and 62 that are present are overlapped with each other. Then, as shown in FIG. 11, concrete is placed between the joint end faces 56 and 66 of both PC beam members 50 and 60.
In this way, a pair of adjacent PC beam members 50 and 60 can be joined together.
図12に示す接合方法は、いわゆる横挿工法であって、予め、他方のPC梁部材60に打継ぎ用継手63を埋設しておき、一方のPC梁部材50の主筋52を接合端面56から所定の長さ突出させておく。そして、両PC梁部材50、60を所定の位置に位置決めし、接合端面56、66同士を互いに対向させ、一方のPC梁部材50を他方のPC梁部材60の方向に相対的に水平移動させ、打継ぎ用継手63に主筋52を差し込む。このようにして、隣接する一対のPC梁部材50、60間を一体に接合することができる。   The joining method shown in FIG. 12 is a so-called transverse insertion method, in which a joint 63 for jointing is embedded in the other PC beam member 60 in advance, and the main bar 52 of one PC beam member 50 is connected to the joining end surface 56. It protrudes for a predetermined length. Then, both the PC beam members 50 and 60 are positioned at predetermined positions, the joint end surfaces 56 and 66 are opposed to each other, and one PC beam member 50 is relatively horizontally moved in the direction of the other PC beam member 60. The main bar 52 is inserted into the joint 63 for joining. In this way, a pair of adjacent PC beam members 50 and 60 can be joined together.
ところで、上記のような接合方法のうち、図10及び図11に記載されている接合方法は、現場において、隣接するPC梁部材50、60間の接合部にコンクリートを打設する必要があるため、サポート等によって両PC梁部材50、60を支持した状態でコンクリートを打設しなければならない。   By the way, among the joining methods as described above, the joining method described in FIGS. 10 and 11 needs to place concrete at the joint between adjacent PC beam members 50 and 60 in the field. Concrete must be placed in a state where both the PC beam members 50 and 60 are supported by a support or the like.
このため、打設したコンクリートが硬化して両PC梁部材50、60と一体化するまではサポート等を取り外すことができず、サポート等が作業の邪魔になるため、両PC梁部材50、60の下方の部分、及び上方の部分の施工を連続して行うことができず、工期が延びてしまう。  For this reason, the support or the like cannot be removed until the placed concrete is cured and integrated with both the PC beam members 50 and 60, and the support and the like interferes with the work. The construction of the lower part and the upper part cannot be continuously performed, and the construction period is extended.
また、両PC梁部材50、60の接合部にコンクリートを打設しなければならない。このため、両PC梁部材50、60間の接合部においてせん断補強筋の配筋や型枠の組み立て作業が生じるため、工期が長くなる。   In addition, concrete must be placed at the joint between the PC beam members 50 and 60. For this reason, since the reinforcement work of a shear reinforcement and the assembly work of a formwork arise in the junction part between both PC beam members 50 and 60, a construction period becomes long.
このような問題に対処するため、両PC梁部材50、60間の接合部及びスラブへのコンクリートの打設に同一のコンクリート(高い方の設計基準強度のコンクリート)を打設することも考えられるが、その場合には、工期を短縮することができても、必要以上に強度の高いコンクリートを使用しなければならないため、施工費が高くついてしまう。  In order to cope with such a problem, it is conceivable that the same concrete (concrete having a higher design standard strength) is placed in the joint between the PC beam members 50 and 60 and the concrete is placed in the slab. However, in that case, even if the construction period can be shortened, the construction cost is high because it is necessary to use concrete having a higher strength than necessary.
さらに、図12に記載されている接合方法は、一方のPC梁部材50又は他方のPC梁部材60を水平移動させなければならないため、移動に必要な広い空間を確保しなければならない。さらに、一方のPC梁部材50又は他方のPC梁部材60を水平移動させる際に、既に建て込まれた柱などが障害となるため、両PC梁部材50、60を移動させる工程を考慮した施工手順を計画しなければならず、施工手順が複雑になり、工期が長くなる。さらに、建て込む上で、両PC梁部材50、60を水平移動させることができない箇所が必ず生じるため、そのような箇所には現場でコンクリートを打設しなければならない。   Furthermore, in the joining method described in FIG. 12, one PC beam member 50 or the other PC beam member 60 must be moved horizontally, so that a wide space necessary for the movement must be ensured. Furthermore, when one PC beam member 50 or the other PC beam member 60 is moved horizontally, an already built pillar or the like becomes an obstacle, and therefore, the construction considering the process of moving both PC beam members 50 and 60 is considered. The procedure must be planned, the construction procedure becomes complicated, and the construction period becomes longer. Furthermore, since there are places where the PC beam members 50 and 60 cannot be moved horizontally when building, concrete must be placed on such places in the field.
本発明は、前記のような従来の問題に鑑みなされたものであって、柱や梁等のPC部材に適用した場合に、施工が容易で工期を大幅に短縮することができる接合構造及び接合方法を提供することを目的とする。   The present invention has been made in view of the above-described conventional problems. When applied to a PC member such as a column or a beam, the present invention is easy to install and can significantly reduce the construction period. It aims to provide a method.

As shown in FIG. 1, the threaded joint 31 is preliminarily screwed to the male threaded portion 23 of one of the main bars 12 or the other main bar 22 (the other main bar 22 in this embodiment).
そして、上記のような構成の接合構造1により隣接する一対のPC梁部材10、20間を接合するには、まず、図1に示すように、一方のPC梁部材10に対して他方のPC梁部材20を上下方向に相対的に移動させ、一方のPC梁部材10の接合端面15と他方のPC梁部材20の接合端面25とを上下方向から合致させる。   And in order to join between a pair of adjacent PC beam members 10 and 20 by the joining structure 1 having the above-described configuration, first, as shown in FIG. The beam member 20 is relatively moved in the vertical direction so that the joint end surface 15 of one PC beam member 10 and the joint end surface 25 of the other PC beam member 20 are aligned in the vertical direction.
次に、図4に示すように、他方の主筋22の雄ねじ部23に螺着されているねじ式継手31を、他方の主筋22に沿って螺進させて、一方の主筋12の雄ねじ部13に螺着させ、ねじ式継手31を両雄ねじ部13、23の外側に被嵌させ、両雄ねじ部13、23間をねじ式継手31を介して一体に接合する。この場合、両雄ねじ部13、23の先端面同士が長手方向の中間で密着するように、両雄ねじ部13、23の外側にねじ式継手31を螺着させる。   Next, as shown in FIG. 4, the threaded joint 31 screwed to the male thread portion 23 of the other main muscle 22 is screwed along the other main muscle 22, and the male thread portion 13 of the one main muscle 12. The threaded joint 31 is fitted on the outside of the male threaded portions 13 and 23, and the male threaded parts 13 and 23 are joined together via the threaded joint 31. In this case, the threaded joint 31 is screwed to the outside of the male screw portions 13 and 23 so that the front end surfaces of the male screw portions 13 and 23 are in close contact with each other in the longitudinal direction.
この場合、ねじ式継手31の雌ねじ部32の内周面と両雄ねじ部13、23との間に、必要に応じて、樹脂、グラウト等の充填材(図示せず)を充填し、ねじ式継手31の雌ねじ部32の内周面と両雄ねじ部13、23の周面との間の隙間を埋める。   In this case, a filler (not shown) such as resin or grout is filled between the inner peripheral surface of the female threaded portion 32 of the threaded joint 31 and the male threaded portions 13 and 23 as necessary, and is threaded. A gap between the inner peripheral surface of the female screw portion 32 of the joint 31 and the peripheral surfaces of both male screw portions 13 and 23 is filled.
次に、図5に示すように、両PC梁部材10、20の両切欠部14、24内にコンクリート35を吹付け等によって充填し、両主筋12、22の接合部をコンクリート35内に埋設させ、両主筋12、22の一端部間を接合手段30を介して接合した状態に保持する。さらに、必要に応じて、両PC梁部材10、20の両接合端面15、25間にグラウトを充填し、両接合端面15、25間に目地処理33を施す。   Next, as shown in FIG. 5, the concrete 35 is filled into the notches 14 and 24 of both the PC beam members 10 and 20 by spraying or the like, and the joint portions of both main bars 12 and 22 are embedded in the concrete 35. Then, the one end portions of both main muscles 12 and 22 are held in a joined state via the joining means 30. Further, if necessary, a grout is filled between the joint end faces 15 and 25 of the PC beam members 10 and 20, and joint treatment 33 is performed between the joint end faces 15 and 25.
このようにして、一方の主筋12の一端部と他方の主筋22の一端部との間をねじ式継手31を介して接合することにより、隣接する一方のPC梁部材10と他方のPC梁部材20との間を一体に接合することができる。   In this way, by joining the one end of one main bar 12 and one end of the other main bar 22 via the threaded joint 31, one adjacent PC beam member 10 and the other PC beam member are joined. 20 can be joined together.
なお、上記の場合、接合手段30として、ねじ式継手31の代わりにスリーブ式継手を用い、スリーブ式継手を一方の主筋12の一端部及び他方の主筋22の一端部の外側に被嵌させることにより、一方の主筋12の一端部と他方の主筋22の一端部との間を接合してもよいし、その他の公知の継手を使用して両主筋12、22の一端部間を接合してもよい。   In the above case, a sleeve-type joint is used as the joining means 30 instead of the screw-type joint 31, and the sleeve-type joint is fitted on the outer side of one end of one main bar 12 and one end of the other main bar 22. Thus, one end of one main muscle 12 and one end of the other main muscle 22 may be joined together, or other known joints may be used to join between one end of both main muscles 12 and 22.

Both PC beam members are formed by integrally joining one end portion of one main bar 12 located at one end and one end portion of the other main bar 22 located in the other cutout portion 24 via a joining means 30. The joint end surfaces 15 and 25 of 10 and 20 can be joined together.
従って、現場において、両PC梁部材10、20間の接合部にコンクリートを打設する必要がないので、両PC梁部材10、20を支持するためのサポート等が不要となり、両PC梁部材10、20間の接合に連続して、両PC梁部材10、20の下方の部分及び上方の部分の施工を行うことができ、工期を短縮することができる。   Accordingly, since it is not necessary to place concrete at the joint between the PC beam members 10 and 20 at the site, support for supporting the PC beam members 10 and 20 becomes unnecessary, and both the PC beam members 10 and 20 are not required. , 20 can be applied to the lower part and the upper part of the PC beam members 10, 20 in succession to the joint between the two, and the construction period can be shortened.
また、両PC梁部材10、20間の接合部にコンクリートを打設する必要がないので、鉄筋工事や型枠工事を減少させることができ、これによっても工期を短縮することができる。  Moreover, since it is not necessary to cast concrete in the joint part between both the PC beam members 10 and 20, rebar construction and formwork can be reduced, and this can also shorten the construction period.
さらに、一方のPC梁部材10の接合端面15と他方のPC梁部材20の接合端面25とを合わせて、一方の主筋12の一端部と他方の主筋22の一端部とを接合手段30により接合するだけでよいので、両PC梁部材10、20を水平方向に移動させるために広い移動空間を必要とすることはなく、また、建て込む順序が複雑になるようなこともない。   Further, the joining end face 15 of one PC beam member 10 and the joining end face 25 of the other PC beam member 20 are combined, and one end of one main bar 12 and one end of the other main bar 22 are joined by the joining means 30. Therefore, there is no need for a wide movement space for moving both the PC beam members 10 and 20 in the horizontal direction, and the order of installation is not complicated.
