層建築物におけるシャーコネクターを利用した床板固定
構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a floor plate fixing structure using shear connectors in medium and low-rise buildings such as houses, apartments, condominiums, and schools.
従来、住宅あるいは中低層建築物においては、鉄骨軸組
ＡＬＣ住宅やプレキャストコンクリートパネル（以下、
単にパネルという）を用いた壁構造の建物などパネルを
主体としたものが種々開発されており、乾式１法による
施工性の向上が図られている。Conventionally, for houses or medium-low-rise buildings, steel frame ALC houses and precast concrete panels (hereinafter referred to as
A variety of wall structures have been developed, such as buildings with wall structures using panels (simply referred to as panels), and efforts are being made to improve construction efficiency using the dry method.
ところで、鉄骨軸組構造では開口を比較的自由に計画す
ることができるが、一般に壁式構造においては開口部の
補強などに非常に手間がかかり、また設計の自由度が制
限される。Incidentally, in a steel framework structure, the opening can be planned relatively freely, but in a wall-type structure, reinforcing the opening generally takes a lot of effort, and the degree of freedom in design is restricted.
そこで、出願人は低コストで、施工性がよく、かつ設計
の自由度が大きい高性能の建物躯体構造として、桁行方

コンクリート中に、一端が前記架構の鉄骨梁に接合され
るシャーコネクターを配した床構造を提案している（特
開平１−２１１５１号公報参照）。Therefore, the applicant proposed a high-performance building frame structure that is low cost, easy to construct, and has a large degree of freedom in design.The walls in the girder direction are made of steel frames, and the walls in the span direction are made of multiple frames. We are developing a building with a wall structure made of panels arranged side by side. In addition, the floor structure in such a building consists of a plurality of panels of a predetermined width spanned horizontally on the building frame and concrete of a predetermined thickness poured on top of the panels, with one end in the concrete. A floor structure has been proposed in which shear connectors are connected to the steel beams of the frame (see Japanese Patent Laid-Open No. 1-21151).
シャーコネクターを鉄骨梁部分と床部分の間の応力伝達
に使用する場合、基部を直接鉄骨梁にボルトナツト式に
あるいは溶接により固定する方法が考えられるが、施工
の関係から通常、パネル架設後に現場で配設されるため

接により固定するには手間がかかり、施工精度確保の観
点からも改善の余地がある。When using a shear connector to transmit stress between a steel beam and a floor, it is possible to fix the base directly to the steel beam with bolts and nuts or by welding, but due to construction considerations, it is usually done on-site after the panel is erected. Because of the large number of shear connectors, it takes time and effort to fix them using bolts and nuts or welding, and there is room for improvement from the perspective of ensuring construction accuracy.
本発明の床板固定構造は上述のような事情のもとに発明
されたものである。The floor plate fixing structure of the present invention was invented under the above-mentioned circumstances.

２に固定された梁方向鉄筋４を利用して設置される。Figures 1, 3, and 4 show how the shear connectors 1 are installed on the outer periphery of the floor plate 13, extending from the steel beam 12 position in the tension direction. It is installed using a downward-facing 0-shaped metal fitting 2 and a beam direction reinforcing bar 4 fixed to the 0-shaped metal fitting 2.

する位置合わせが容易となる。FIG. 6 shows an example of a shear connector 5 fixed to a panel 21 constituting an outer wall and extending in the column direction.
Since there is no steel beam 12, a screw is provided at the fixed end of the rod-shaped shear connector 5, and the screw is inserted through the panel 2I to attach the napht 6.
It is fixed at Note that the threaded part 5a has a smaller diameter than the part without a screw, so by adjusting the diameter of the through hole of the panel 21 to this, it is possible to catch the threaded part 5a at the boundary with other parts, and the jar connector 5 can be easily aligned in the longitudinal direction.
鉄筋メソシュ１６は通常シャーコネクターの設置後に敷
設され、その後コンクリート１７が打設される。The reinforcing bar mesh 16 is usually laid after the shear connector is installed, and then the concrete 17 is poured.

Instead, the shear connector bent into an L shape is locked to the reinforcing bar in the beam direction, and its base tip is inserted into the U-shaped space of the U-shaped fitting. The work efficiency is improved because all you have to do is to
