［実施例１］
図１および図２に示すように、本発明の実施例１に係る柱パネルゾーンフルＰＣ一体大梁鉄筋ユニット構工法は、１階層１節分の柱を一体的に構成し、上面から上方向に突き出た柱鉄筋１４を有するフルＰＣ柱部材１０（柱１層１節フルＰＣ柱）と、部材の軽量化を目的として大梁を構成する鉄筋ユニット１６と、この鉄筋ユニット１６と一体化され、柱鉄筋１４を挿通するための挿通孔１８ａを有する柱パネルゾーンフルＰＣ部材１８とからなる大梁部材１２とを、ＰＣ部材１８の挿通孔１８ａに柱鉄筋１４を挿通して接合するものである。この実施例１の構工法によって構築される構造が柱梁構造１００である。柱梁構面には、ＰＣＦまたはＰＣカーテンウォールからなる壁が構築されることとなる。 [Example 1]
As shown in FIGS. 1 and 2, the column panel zone full PC integrated large beam reinforcing bar unit construction method according to the first embodiment of the present invention is configured by integrally forming columns for one level and one node and projecting upward from the upper surface. A full PC column member 10 (column 1 layer 1 node full PC column) having a column reinforcing bar 14, a reinforcing bar unit 16 constituting a large beam for the purpose of reducing the weight of the member, and the reinforcing bar unit 16 are integrated with the column reinforcing bar. The large beam member 12 including the column panel zone full PC member 18 having the insertion hole 18 a for inserting the column 14 is inserted into the insertion hole 18 a of the PC member 18 through the column rebar 14 and joined. A structure constructed by the construction method of the first embodiment is a column beam structure 100. A wall made of PCF or PC curtain wall is constructed on the column beam construction surface.

大梁部材１２は、１個以上のＰＣ部材１８と、これらを接続する鉄筋ユニット１６とからなる柱パネルゾーン１連ＰＣ一体大梁鉄筋ユニットである。鉄筋ユニット１６は、２つの柱パネルゾーンを跨いでなる２スパン分の梁を構成する柱パネルゾーンフルＰＣ一体の鉄筋のユニットである。鉄筋ユニット１６は主筋１６ａを有する。この主筋１６ａは、施工方法、運搬等の状況により１本物、ジョイント物を用いることが可能である。なお、鉄筋ユニット１６は、１スパン分の梁を構成することもできる。 The girder member 12 is a column panel zone 1-unit PC-integrated girder rebar unit that includes one or more PC members 18 and a rebar unit 16 that connects them. The reinforcing bar unit 16 is a reinforcing bar unit integrated with a column panel zone full PC that constitutes a beam for two spans straddling two column panel zones. The reinforcing bar unit 16 has a main reinforcing bar 16a. This main reinforcement 16a can use one thing and a joint thing by the conditions, such as a construction method and conveyance. The reinforcing bar unit 16 can also constitute a beam for one span.

また、柱パネルゾーンフルＰＣ部材１８は、２つの柱パネルゾーンに設けられるフルＰＣの部材である。大梁部材１２は、鉄筋ユニット１６をＰＣＦや型枠で覆いコンクリートを充填する公知の大梁ＰＣＦ工法により、大梁とすることができる。大梁用のＰＣＦとしては、Ｉ型ＰＣＦ、Ｌ型ＰＣＦ等を用いることができる。また、大梁部材１２同士は、場所打ちコンクリート２０で接合される。 The column panel zone full PC member 18 is a full PC member provided in two column panel zones. The girder member 12 can be a girder by a known girder PCF method in which the reinforcing bar unit 16 is covered with PCF or a formwork and filled with concrete. As the PCF for the large beam, I-type PCF, L-type PCF, or the like can be used. Further, the large beam members 12 are joined together by cast-in-place concrete 20.

このため、本実施例１によれば、柱パネルゾーンに現場打ちコンクリートを打設する必要がなくなり、養生期間を待つことなく上階の柱を構築する後続の工程に進むことができる。また、柱部分がＰＣ柱部材１０と、柱パネルゾーンフルＰＣ部材１８とに分離されて揚重部材の重量減が可能となり施工性向上を図ることができる。このため、揚重負荷を軽減して工期を短縮することができる安価な柱パネルゾーンフルＰＣ一体大梁鉄筋ユニット構工法を提供することができるという効果を奏する。 For this reason, according to the first embodiment, it is not necessary to place the cast-in-place concrete in the column panel zone, and it is possible to proceed to the subsequent step of constructing the upper floor column without waiting for the curing period. In addition, the column portion is separated into the PC column member 10 and the column panel zone full PC member 18 so that the weight of the lifting member can be reduced and the workability can be improved. For this reason, there is an effect that it is possible to provide an inexpensive column panel zone full PC integrated large beam reinforcing bar construction method capable of reducing the lifting load and shortening the construction period.

特に、床スラブ配筋時にＰＣ柱の施工ができるため、従来の工法に比べ工程を短縮することができる。例えば、従来５日であった基準階サイクル工程日数を４日に短縮することができる。 In particular, since the PC pillar can be constructed at the time of floor slab reinforcement, the process can be shortened compared to the conventional method. For example, the standard floor cycle process days, which was conventionally 5 days, can be shortened to 4 days.

また、大梁の主筋のジョイント部がほぼ半分となるので、機械式継手の物量を減らすことができ、作業量低減による施工性向上を図ることができる。したがって、タワークレーンの揚重負担を軽減しコストダウンを図ることができる。 Further, since the joint portion of the main bar of the large beam is almost halved, the amount of mechanical joints can be reduced, and the workability can be improved by reducing the amount of work. Therefore, the lifting load of the tower crane can be reduced and the cost can be reduced.

なお、図１０は、従来のタイプ１の柱梁構築方法を示す図である。図１０に示すように、従来のタイプ１の柱梁構築方法は、鉄筋３、４を備える柱１と、鉄筋ユニットからなる梁２とを接合し、梁２同士を場所打ちコンクリート５で接合したものである。 FIG. 10 is a diagram showing a conventional type 1 column beam construction method. As shown in FIG. 10, in the conventional type 1 column beam construction method, a column 1 including reinforcing bars 3 and 4 and a beam 2 made of a reinforcing bar unit are joined, and the beams 2 are joined with cast-in-place concrete 5. Is.

本実施例１の工程は図６に示すとおりであり、従来のタイプ１の工程は図８に示すとおりである。図６および図８を比較すると、本実施例１は、従来のタイプ１の柱梁構築方法に比べて、工程が短縮化され、コスト的に有利であることがわかる。 The process of Example 1 is as shown in FIG. 6, and the conventional type 1 process is as shown in FIG. Comparing FIG. 6 and FIG. 8, it can be seen that the first embodiment is advantageous in terms of cost because the process is shortened as compared with the conventional type 1 column beam construction method.

［実施例１の変形例］
図３および図４に示すように、本発明の実施例１の変形例は、大梁部材２２がジョイント２４で接合した主筋１６ａを有する構成となっている。大梁部材２２のジョイント２４の位置としては、中央ジョイントのほか、端部ジョイントや任意位置でのジョイントとすることができる。 [Modification of Example 1]
As shown in FIGS. 3 and 4, the modification of the first embodiment of the present invention has a configuration in which a large beam member 22 has a main bar 16 a joined by a joint 24. As a position of the joint 24 of the large beam member 22, in addition to the center joint, an end joint or a joint at an arbitrary position can be used.
