〔産業上の利用分野〕
本考案は、プレストレストコンクリート（以下
PCと記す）プレキヤストスラブに関し、さらに
詳しくは同一合成梁成で施工時の断面性能を向上
させたPCプレキヤスト版に関する。[Detailed explanation of the invention] [Industrial application field] This invention is a prestressed concrete (hereinafter referred to as
Regarding pre-cast slabs (referred to as PC), more specifically regarding PC pre-cast slabs with improved cross-sectional performance during construction using the same composite beam structure.
建築物のスラブをPCの合成スラブによつて形
成するとスラブの支保工や型枠を無くすることが
でき、工期の短縮、水平剛性の向上を図ることが
できるなどの利点がある。
When building slabs are made of composite PC slabs, slab supports and formwork can be eliminated, which has the advantage of shortening the construction period and improving horizontal rigidity.
しかし、この場合にトツピングコンクリートは
施工時にPC版と一体化して有効合成断面を構成
することはなく、トツピングコンクリート及び
PC版の自重は、すべて合成前のPC床版で受け持
たねばならないため、梁成が大きくなる上、合成
効果を上げるためのジベル筋等を必要とした。 However, in this case, the topping concrete is not integrated with the PC plate to form an effective composite cross section during construction, and the topping concrete and
All of the weight of the PC slab had to be carried by the pre-composed PC floor slab, which increased the beam size and required gibber bars to improve the composite effect.
本考案者らは従来のPCのＴ型スラブの利点を
生かし、さらにこれに改善を加えることによつて
トツピング施工時の断面性能を向上させたスラブ
を開発した。本考案はこのような新規な合成スラ
ブ用PCプレキヤスト版を提供することを目的と
するものである。
The inventors took advantage of the advantages of the conventional PC T-shaped slab and added improvements to it to develop a slab with improved cross-sectional performance during topping construction. The purpose of the present invention is to provide such a novel PC precast plate for composite slabs.
本考案はPC鋼材を下弦に配設したプレストレ
ストコンクリートプレキヤストＴ型スラブにおい
て、スラブの梁部の上面部にトツピングコンクリ
ート厚より高さの低い矩形断面の偏平棒状の連続
した一体コンクリート突起を梁の長手方向に沿つ
て設け、該突起の横面には複数の凹部及び／又は
凸部を設けたことを技術手段とする。
This invention is a prestressed concrete precast T-type slab in which prestressed concrete steel is arranged in the lower chord, and a continuous integral concrete protrusion in the shape of a flat bar with a rectangular cross section and a height lower than the thickness of the topping concrete is installed on the upper surface of the beam of the slab. The technical means is that the protrusion is provided along the longitudinal direction, and a plurality of recesses and/or protrusions are provided on the side surface of the protrusion.
この一定高さの突起は、高さに対して幅の広い
矩形断面の偏平棒状を呈しその横面には適宜の凹
凸、切欠などを付してあり、また突起の外面が粗
面を有するようにすると一層好ましい。 This protrusion of a certain height has the shape of a flat bar with a rectangular cross section that is wide relative to its height, and has appropriate unevenness, notches, etc. on its side surface, and the outer surface of the protrusion has a rough surface. It is even more preferable to do so.
Ｔ型スラブはもちろん、シングルＴ型スラブで
もダブルＴ型スラブでもよい。 It may be a T-shaped slab, a single T-shaped slab, or a double T-shaped slab.
本考案のスラブは、従来の突起のないＴ型スラ
ブに比し梁成を有効にとることができ、トツピン
グ施工時の断面性能が向上する。
The slab of the present invention allows for more effective beam formation than conventional T-shaped slabs without protrusions, and improves cross-sectional performance during topping construction.
すなわち従来のスラブと同一の合成梁成のスラ
ブであつても、突起の部分によつてPC版自体の
断面性能が向上するのである。 In other words, even if the slab is made of the same composite beams as a conventional slab, the cross-sectional performance of the PC plate itself is improved by the protrusions.
突起はトツピングコンクリートのシヤーコネク
タとなるため、トツピングコンクリートも有効に
合成断面を構成することができ、また突起部が高
強度コンクリートであるため剪断に対して有効に
働く。 Since the protrusions serve as shear connectors for the topping concrete, the topping concrete can also effectively form a composite cross section, and since the protrusions are made of high-strength concrete, they work effectively against shear.
さらにトツピングコンクリートの打設に当つ
て、この後打ち部分のスラブ鉄筋８を突起の上に
載置することによつて、配筋位置の正しい位置ぎ
めを容易に行うことができる。 Furthermore, when placing the topping concrete, by placing the slab reinforcing bars 8 of the post-cast portion on top of the protrusions, it is possible to easily position the reinforcing bars correctly.
〔考案の効果〕
本考案のスラブは同一の合成梁成でトツピング
施工時の断面性能が向上し、トツピングコンクリ
ートも有効に合成断面を形成し、また、その鉄筋
位置ぎめを容易にし作業性と信頼性の向上に寄与
する。[Effects of the invention] The slab of this invention improves cross-sectional performance during topping construction with the same composite beam composition, effectively forms a composite cross-section of topping concrete, and facilitates the positioning of reinforcing bars, improving workability. Contributes to improved reliability.
