次に、図7に示すように、フルPC梁部材10及びフルPC床板40の切り欠き部12、42Aにグラウト13を充填する。この充填したグラウト13が硬化することにより、フルPC床板30、40の接合鉄筋31A,42の一方に作用した応力はグラウト13及びコンクリート43を介して他方に伝達され、すなわち、接合鉄筋31A,42同士が重ね継手により接合されることとなり、フルPC床板同士30、40が強固に接合される。また、これと同様に、フルPC床板30、40とフルPC梁部材10との間も強固に接合される。このようにして、フルPC床板30、40同士及びフルPC床板30、40と梁2が接合構造110、120により接合され、梁10により囲まれる空間内に床面1が構築されることとなる。なお、本実施形態では、フルPC床板30、40同士の間の目地やフルPC床板とフルPC梁部材10との間の目地の処理を行っていないが、これらの目地の処理を行ってもよい。目地処理の方法としては、目地にコンクリート、グラウト、又はエポキシなどの充填材を充填してもよいし、目地にゴムなどの弾性体を介装させてもよい。   Next, as shown in FIG. 7, the grout 13 is filled into the notches 12 and 42 </ b> A of the full PC beam member 10 and the full PC floor board 40. As the filled grout 13 is hardened, the stress acting on one of the joining reinforcing bars 31A, 42 of the full PC floor boards 30, 40 is transmitted to the other through the grout 13 and the concrete 43, that is, the joining reinforcing bars 31A, 42. They are joined together by a lap joint, and the full PC floor plates 30 and 40 are joined firmly. Similarly, the full PC floor plates 30 and 40 and the full PC beam member 10 are also firmly joined. In this way, the full PC floor boards 30 and 40 and the full PC floor boards 30 and 40 and the beam 2 are joined by the joint structures 110 and 120, and the floor surface 1 is constructed in the space surrounded by the beams 10. . In the present embodiment, the joints between the full PC floor plates 30 and 40 and the joints between the full PC floor plate and the full PC beam member 10 are not processed. However, even if these joints are processed. Good. As a joint treatment method, the joint may be filled with a filler such as concrete, grout, or epoxy, or an elastic body such as rubber may be interposed in the joint.

以上説明したように、本実施形態の接合構造110、120によれば、接合端面に形成された切り欠き部12、42Aにグラウト13を充填することにより、フルPC床板30、40同士、又はフルPC床板30、40とフルPC梁部材10とを接合することができる。このため、グラウト12の打設量が少なく、ポンプ車などを用いなくても施工を行うことができ、施工の手間を削減することができる。   As described above, according to the joining structures 110 and 120 of the present embodiment, the full PC floor boards 30 and 40 or the full PC floor boards 30 or 40 are filled by filling the notches 12 and 42A formed on the joining end faces with the grout 13. The PC floor plates 30 and 40 and the full PC beam member 10 can be joined. For this reason, the amount of grout 12 to be placed is small, so that construction can be performed without using a pump car or the like, and the labor of construction can be reduced.

なお、本実施形態では、フルPC床板30の接合端面より突出する接合鉄筋31Aに対応する位置に、フルPC床板40に切り欠き部42Aを設けることとしたが、これに限らず、図8に示すように、切り欠き部42Aを連続して(すなわち、複数の接合鉄筋31Aが内部に位置することができるように)設ける構成としてもよい。   In the present embodiment, the cutout portion 42A is provided in the full PC floor board 40 at a position corresponding to the joining reinforcing bar 31A protruding from the joining end face of the full PC floor board 30, but not limited to this, FIG. As shown, the cutout portions 42A may be provided continuously (that is, so that the plurality of joining reinforcing bars 31A can be positioned inside).

なお、上記実施形態では、フルPC床板30、40とフルPC梁部材10との接合部において、フルPC梁部材10に切り欠き部12を設け、フルPC床板30、40に接合端面より突出するように接合鉄筋31B,41Bを埋設する構成としたが、これに限らず、フルPC梁部材に接合端面より突出するように接合鉄筋を埋設し、フルPC床板の接合端面に切り欠き部を設ける構成とすることもできる。ただし、このような場合には、フルPC梁部材を先行して建て込むと、接合端面より突出している接合鉄筋とフルPC床板とが干渉してしまい、フルPC床板を建て込むことができなくなるため、フルPC梁部材に先行してフルPC床板を建て込む必要がある。   In the above embodiment, the notch 12 is provided in the full PC beam member 10 at the joint portion between the full PC floor plates 30 and 40 and the full PC beam member 10, and the full PC floor plates 30 and 40 protrude from the joining end surface. However, the present invention is not limited to this, and the connecting reinforcing bars are embedded in the full PC beam member so as to protrude from the connecting end face, and the notched portion is provided in the connecting end face of the full PC floor board. It can also be configured. However, in such a case, if the full PC beam member is built in advance, the joint rebar protruding from the joint end face interferes with the full PC floor board, and the full PC floor board cannot be built. Therefore, it is necessary to build a full PC floor board prior to the full PC beam member.

また、上記実施形態では、フルPC床板40の接合鉄筋44を切り欠き部42Aの下方に埋設する構成としたが、例えば、接合鉄筋を切り欠き部の側方に埋設する構成としてもよい。図9は、接合鉄筋144を切り欠き部142Aの側方に埋設した場合のフルPC床板140の接合構造150を示し、(A)は、接合する前のフルPC床板130、140の接合端面近傍の鉛直断面図であり、(B)は(A)におけるI−I´断面図であり、(C)はフルPC床板130、140を接合した状態における接合端面近傍の鉛直断面図であり、(D)は(C)におけるII−II´断面図である。同図に示すように、接合鉄筋144は、フルPC床板140を構成するコンクリート143の切り欠き部142Aの側方の近傍に埋設されている。また、フルPC床板130は、接合端面より突出するようにコンクリート133に埋設された接合鉄筋131Aを備える。接合構造150は、接合鉄筋131Aが切り欠き部142A内に位置するように、フルPC床板130、140を建て込み、切り欠き部142A内にグラウト113を充填することにより構築される。接合構造150によっても、フルPC床板130、140同士の接合鉄筋131A、144同士の間で重ね継手が形成されるため、フルPC床板130、140を強固に接合することができる。なお、接合構造150は、フルPC梁部材とフルPC床板とを接合する場合にも適用することができる。   Moreover, in the said embodiment, it was set as the structure which embeds the joining rebar 44 of the full PC floor board 40 below the notch part 42A, For example, it is good also as a structure which embeds a joining rebar to the side of a notch part. FIG. 9 shows the joining structure 150 of the full PC floor board 140 when the joining reinforcing bar 144 is embedded in the side of the notch 142A. FIG. 9A shows the vicinity of the joining end face of the full PC floor boards 130 and 140 before joining. (B) is a cross-sectional view taken along the line II ′ in (A), (C) is a vertical cross-sectional view in the vicinity of the joining end face in a state where the full PC floor plates 130 and 140 are joined, D) is a sectional view taken along line II-II ′ in FIG. As shown in the figure, the joining rebar 144 is embedded in the vicinity of the side of the notch 142 </ b> A of the concrete 143 constituting the full PC floor board 140. Moreover, the full PC floor board 130 is provided with the joining rebar 131A embed | buried under the concrete 133 so that it may protrude from a joining end surface. The joint structure 150 is constructed by building full PC floor plates 130 and 140 so that the joint rebar 131A is located in the notch 142A and filling the grout 113 in the notch 142A. Also by the joining structure 150, since the lap joint is formed between the joining reinforcing bars 131A and 144 of the full PC floor plates 130 and 140, the full PC floor plates 130 and 140 can be firmly joined. In addition, the joining structure 150 can be applied also when joining a full PC beam member and a full PC floor board.

さらに、接合鉄筋244を切り欠き部240内に露出させる構成とすることも可能である。図10は、切り欠き部242A内に接合鉄筋244を露出させた場合のフルPC床板230、240の接合構造250を示す図であり、(A)は、接合する前のフルPC床板の接合端面近傍の鉛直断面図であり、(B)は(A)におけるI−I´断面図であり、(C)はフルPC床板230、240を接合した状態における接合端面近傍の鉛直断面図であり、(D)は(C)におけるII−II´断面図である。同図に示すように、フルPC床板230には、接合端面より突出するように接合鉄筋231Aが埋設されており、フルPC床板240には、上面及び接合端面に開口するように切り欠き部242Aが設けられ、この切り欠き部242A内に露出するように接合鉄筋244が設けられている。これらのフルPC床板240を接合する際には、まず、切り欠き部242Aが設けられたフルPC床板240を建て込み、次に、接合端面より突出するように接合鉄筋231Aが埋設されたフルPC床板230を、接合鉄筋231Aが切り欠き部242A内に位置するように建て込む。そして、切り欠き部242A内にグラウト113を充填する。このグラウト113が硬化することにより、フルPC床板230、240の接合鉄筋231A、244同士が重ね継手により継手され、フルPC床板230、240が接合構造250により接合される。なお、接合構造250は、フルPC梁部材とフルPC床板とを接合する場合にも適用することができる。なお、本実施形態の接合構造250においても、上記実施形態において図8を参照して説明したのと同様に、切り欠き部242Aを連続して設ける構成としてもよい。   Furthermore, it is also possible to adopt a configuration in which the joining rebar 244 is exposed in the notch 240. FIG. 10 is a view showing a joint structure 250 of full PC floor plates 230 and 240 when the joint reinforcing bar 244 is exposed in the notch 242A. FIG. 10A is a joint end surface of the full PC floor plate before joining. It is a vertical cross-sectional view in the vicinity, (B) is a cross-sectional view taken along line II ′ in (A), (C) is a vertical cross-sectional view in the vicinity of the joining end face in a state where the full PC floor plates 230 and 240 are joined, (D) is II-II 'sectional drawing in (C). As shown in the figure, the full PC floor plate 230 is embedded with a reinforcing bar 231A so as to protrude from the joint end surface, and the full PC floor plate 240 has a notch 242A so as to open to the upper surface and the joint end surface. , And a joining rebar 244 is provided so as to be exposed in the notch 242A. When joining these full PC floor plates 240, first, the full PC floor plate 240 provided with the notch 242A is built, and then the full PC in which the joining reinforcing bars 231A are embedded so as to protrude from the joining end face. The floor plate 230 is built so that the joining rebar 231A is located in the notch 242A. Then, the grout 113 is filled into the notch 242A. When the grout 113 is cured, the joint reinforcing bars 231A and 244 of the full PC floor plates 230 and 240 are joined together by a lap joint, and the full PC floor plates 230 and 240 are joined by the joint structure 250. In addition, the joining structure 250 can be applied also when joining a full PC beam member and a full PC floor board. Note that the joint structure 250 of the present embodiment may also be configured to continuously provide the notches 242A, as described with reference to FIG. 8 in the above embodiment.

また、図1〜図7を参照して説明した実施形態では、フルPC床板40の接合端部には切り欠き部42Aのみを設け、フルPC床板30の接合端部には端面より突出するように接合鉄筋31Aのみを設け、フルPC床板40側で接合鉄筋31A,44を継手する構成としたが、これに限らず、図11に示すように、フルPC床板30にも接合端面に切り欠き部32Aを設け、この近傍に接合鉄筋を埋設するとともに、フルPC床板40にも接合端面より突出するように接合鉄筋31Aを突出させておいてもよい。これらのフルPC床板30、40は、フルPC床板30の接合鉄筋31Aが、フルPC床板40の切り欠き部42A内に位置するとともに、フルPC床板40の接合鉄筋41AがフルPC床板30の切り欠き部32A内に位置するように建て込み、切り欠き部32A,42A内にグラウトを充填することにより接合することができる。なお、これと同様に、図9及び図10を参照して説明した接合方法を用いる場合にも、切り欠き部を一対のフルPC床板の両方に設けておき、切り欠き部の設けられた側のフルPC床板内において重ね継手を形成して接合することも可能である。   Moreover, in embodiment described with reference to FIGS. 1-7, only the notch part 42A is provided in the joining edge part of the full PC floor board 40, and it protrudes from an end surface in the joining edge part of the full PC floor board 30. However, the present invention is not limited to this, and as shown in FIG. 11, the full PC floor plate 30 is notched at the joint end face. It is also possible to provide the portion 32A and embed the joining rebar in the vicinity thereof, and also project the joining rebar 31A so as to project from the joining end face to the full PC floor board 40 as well. These full PC floor boards 30, 40 have the joint rebar 31 </ b> A of the full PC floor board 30 located in the notch 42 </ b> A of the full PC floor board 40 and the joint rebar 41 </ b> A of the full PC floor board 40 of the full PC floor board 30. It can be joined by being built so as to be located in the notch 32A and filling the notches 32A and 42A with grout. Similarly, in the case of using the joining method described with reference to FIGS. 9 and 10, the notch portions are provided on both of the pair of full PC floor boards, and the side on which the notch portions are provided. It is also possible to form a lap joint in the full PC floor board.

また、これに限らず、一対のフルPC床板の接合端面及び上面に開口するように切り欠き部を設けておき、これら切り欠き部を跨ぐように重ね鉄筋を設置し、切り欠き部内にグラウトを充填することにより接合鉄筋と重ね鉄筋との間を重ね継手により継手することにより接合することも可能である。図12は、かかる構成の接合構造350によりフルPC床板330、340を接合する方法を説明するための図であり、(A)は、接合する前のフルPC床板330、340の接合端面近傍の鉛直断面図であり、(B)は(A)におけるI−I´断面図であり、(C)はフルPC床板3340、340を接合した状態における接合端面近傍の鉛直断面図であり、(D)は(C)におけるII−II´断面図である。同図に示すように、各フルPC床板330、340の接合端部には接合端面及び上面に開口するように切り欠き部332A、342Aが設けられており、これら切り欠き部332A、342Aの下方には接合鉄筋334,344が埋設されている。これらの切り欠き部332A、342AはフルPC床板330、340の接合端面同士を当接させた状態において、一体となって凹部を形成するように形成されている。   In addition to this, a notch portion is provided so as to open on the joining end surface and the upper surface of a pair of full PC floor boards, a reinforced reinforcing bar is installed so as to straddle these notch portions, and a grout is placed in the notch portion. It is also possible to join by filling the jointed reinforcing bars and the lap reinforcing bars with a lap joint. FIG. 12 is a view for explaining a method of joining the full PC floor plates 330 and 340 by the joining structure 350 having such a configuration. FIG. 12A is a view of the vicinity of the joining end face of the full PC floor plates 330 and 340 before joining. It is a vertical sectional view, (B) is a sectional view taken along line II ′ in (A), (C) is a vertical sectional view in the vicinity of the joining end face in a state where full PC floor plates 3340 and 340 are joined, (D ) Is a sectional view taken along line II-II ′ in FIG. As shown in the drawing, notch portions 332A and 342A are provided at the joining end portions of the full PC floor plates 330 and 340 so as to open to the joining end surface and the upper surface, and below these notch portions 332A and 342A. Are embedded with reinforcing bars 334 and 344. These notches 332A and 342A are formed so as to form a concave portion integrally in a state where the joining end faces of the full PC floor plates 330 and 340 are in contact with each other.

これらのフルPC床板330、340を接合する際には、まず、フルPC床板330、340を接合端面が互いに当接するように建て込む。これにより、一対のフルPC床板330、340の切り欠き部332A、342Aが一体となって凹部を形成することとなる。なお、この際、接合鉄筋334、344が端部より突出しておらず、他の部材に干渉することがなく、何れのフルPC床板330、340を先行して建て込んでもよい。次に、切り欠き部332A、342Aにより形成された凹部に各フルPC床板330、340の接合鉄筋334、344と部分的に重なりあうように重ね鉄筋350を設置する。次に、凹部内にグラウト313を充填する。このグラウト313が硬化することにより、各フルPC床板330,340の接合鉄筋334、344と重ね鉄筋350との間で重ね継手が形成され、フルPC床板330、340の接合鉄筋334、344同士の間で応力の伝達が可能となる。これにより、接合構造360が形成され、フルPC床板330、340が強固に接合される。なお、接合構造360は、フルPC梁部材とフルPC床板との接合にも適用することができる。また、本実施形態では、接合鉄筋334、344をコンクリート333、343に埋設する構成としているが、これに限らず、切り欠き部332A,342A内に露出するように設ける構成としてもよい。また、本実施形態の接合構造350においても、上記実施形態において図8を参照して説明したのと同様に、切り欠き部332A,342Aを連続して設ける構成としてもよい。   When joining these full PC floor boards 330 and 340, first, the full PC floor boards 330 and 340 are built so that the joining end faces come into contact with each other. As a result, the notches 332A and 342A of the pair of full PC floor plates 330 and 340 are integrated to form a recess. At this time, the joining reinforcing bars 334 and 344 do not protrude from the end portions and do not interfere with other members, and any of the full PC floor plates 330 and 340 may be built in advance. Next, the overlapping reinforcing bars 350 are installed in the concave portions formed by the notches 332A and 342A so as to partially overlap the joining reinforcing bars 334 and 344 of the full PC floor plates 330 and 340. Next, the grout 313 is filled in the recess. When the grout 313 is cured, a lap joint is formed between the joint reinforcing bars 334 and 344 of the full PC floor plates 330 and 340 and the lap reinforcing bar 350, and the joint reinforcing bars 334 and 344 of the full PC floor plates 330 and 340 are connected to each other. Stress can be transmitted between the two. Thereby, the joining structure 360 is formed, and the full PC floor boards 330 and 340 are joined firmly. The joining structure 360 can also be applied to joining a full PC beam member and a full PC floor board. In the present embodiment, the joining reinforcing bars 334 and 344 are embedded in the concrete 333 and 343. However, the present invention is not limited to this, and the connecting reinforcing bars 334 and 344 may be provided so as to be exposed in the notches 332A and 342A. Further, in the bonding structure 350 of the present embodiment, the notches 332A and 342A may be provided continuously as described in the above embodiment with reference to FIG.

かかる構成の接合構造は、接合端面より接合鉄筋を突出させなくてもよいので、フルPC部材を建て込む際に、他の部材に干渉することがない。このため、PC部材の建て込み順序が自由になるという利点がある。   In the joining structure having such a configuration, it is not necessary to project the joining reinforcing bar from the joining end face, and therefore, when the full PC member is built, it does not interfere with other members. For this reason, there exists an advantage that the embedding order of PC member becomes free.

なお、上記の各実施形態では、接合鉄筋をスラブ筋や梁筋とは別に設ける構成としたが、これに限らず、スラブ筋や梁筋を接合鉄筋として用いることも可能である。   In each of the above embodiments, the joining reinforcing bars are provided separately from the slab reinforcing bars and the beam reinforcing bars.
