本発明は床スラブを支持する柱から柱頭（キャピタル）
をなくしたフラットスラブに関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a method for supporting a floor slab from a column to a capital.
Regarding flat slabs that have lost.
（従来の技術）
一般に、フラットスラブは床スラブを柱で直接支持する
構造である。このフラットスラブの構造は、第５，６図
に示すように柱２周辺にせん断力が集中してくるために
、柱の上端に柱頭Ｐａ（必要に応じて柱頭とスラブとの
間に支板）を設けなければならない。(Prior Art) Generally, a flat slab has a structure in which a floor slab is directly supported by columns. In this flat slab structure, as shown in Figures 5 and 6, the shear force concentrates around the column 2, so the upper end of the column has a column capital Pa (a supporting plate is placed between the column capital and the slab if necessary). ) must be provided.

構成上の大きな障害となっていた。(Problem to be solved by the invention) However, according to the conventional flat slab, a capital approximately twice the thickness of the slab is attached to the top of the column, and this capital covers the piping in the ceiling and the floor height of the building. This was a major hindrance in terms of architectural planning, equipment planning, and space configuration.
本発明の目的は、従来のようにフラットスラブを採用す
ることによって生ずる建築計画上、設備計画上の納まり
の制約をなくし、空間構成上の大きな障害をなくするこ
とにある。An object of the present invention is to eliminate constraints on architectural planning and equipment planning caused by conventional use of flat slabs, and to eliminate major obstacles in space configuration.

本発明は、柱１とスラブ２とが接合する位置のスラブ内
に補強具３を埋設しているものである。(Means for Solving the Problems) In the present invention, a reinforcing tool 3 is embedded in the slab at a position where the column 1 and the slab 2 are joined.

。This reinforcing device consists of both upper and lower plates 4.5 and a connecting wire 6 that connects both plates, and the connecting wire is the upper plate 4.5.
The lower plate 5 is arranged to be inclined outward. For example, a reinforcing bar or a flat bar is used as the connecting wire.
（作用） 補強具３が集中してくるせん断力を直接柱１に伝える。(effect) The reinforcement 3 directly transmits the concentrated shear force to the column 1.
（実施例） 以下本発明の詳細な説明する。(Example) The present invention will be explained in detail below.

ート４の外径は柱１の断面より大きく設定してあり、ま
た下プレート５の直径は上プレートの外径より大きい。In FIGS. 1 and 2, a reinforcing tool 3 is embedded in the slab at the joining position of the column 1 and the slab 2. This reinforcing device is made up of a ring-shaped upper plate 4 made of steel, a lower plate 5 made of a steel disc located below it at a predetermined distance, and a connecting reinforcing bar 6 connecting both plates. Become. The outer diameter of the upper plate 4 is set larger than the cross section of the column 1, and the diameter of the lower plate 5 is larger than the outer diameter of the upper plate.

レート５４が突設してある。A hole 51 having an inner diameter substantially matching the cross section of the column 1 is bored in the center of the lower plate 5 so that poured concrete can be filled downward from the column force. A rising portion 52 is provided at the edge of the hole 51 to strengthen the area around the hole in the lower plate 5 and to integrate this plate with the concrete of the slab 2. Like the rising portion 52, studs 53 are planted at equal intervals on the upper surface of the lower plate 5 so as to surround the hole 51, in hopes of integrating with the slab concrete. A capital reinforcing plate 54 protrudes from the lower surface around the hole 51.

されることになる。Further, the connecting reinforcing bars 6 are arranged radially outward from the upper plate 4 toward the lower plate 5, and the lower end of each reinforcing bar is fixed to the outer periphery of the lower plate. Therefore, each connecting reinforcing bar 6 is arranged diagonally between the upper and lower plates 4 and 5 as shown in FIG.
せん断力の流れは、第３，４図に示す矢印のようになり
、集中してくる力を補強具３が直接柱１に伝達する。The flow of shear force is as shown by the arrows shown in FIGS. 3 and 4, and the reinforcing tool 3 directly transmits the concentrated force to the column 1.
