この考案はコンクリート柱と鉄骨梁との接合部
において対向する鉄骨梁を接続する、柱・梁接合
部における梁接合用金物に関するものである。[Detailed description of the invention] [Field of industrial application] This invention relates to a beam joining hardware at a column-beam joint, which connects opposing steel beams at the joint between a concrete column and a steel beam.
コンクリート柱と鉄骨梁の接合部において両者

ボルト状の金物を提案している。
It is preferable that the metal fittings used to connect concrete columns and steel beams at joints do not impede the filling properties of concrete and the workability of reinforcing for concrete columns, and in response to this request, the applicant proposed a battledore bolt-shaped hardware in Utility Application No. 106336/1983.

達には限度があるためこの金物ではコンクリート
柱の構造設計上大きな効果は期待できない。 By the way, this hardware is said to have a mechanism that transmits the stress from the steel beam to the concrete column by the adhesion strength between the steel rod-shaped part embedded in the column and the concrete, but there is a limit to the transmission of stress due to the adhesion of concrete. Therefore, this hardware cannot be expected to have a great effect on the structural design of concrete columns.
この考案は以上のコンクリートの付着に期待す

である。 This idea was made with the aim of improving the metal fittings that are expected to help concrete adhere, and further increasing the stress transmission effect. However, this is attempted to be achieved by making the part buried within the concrete pillar into a flat plate.

とを可能にする。
In this invention, we focused on the fact that the bearing strength of concrete is much greater than the adhesive strength, so we made the shape of the hardware cross-shaped and formed the orthogonal parts within the column into vertically long flat plates. The structure is such that the bearing effect is exerted in the vertically elongated portion in the direction perpendicular to the direction in which the stress is applied, making it possible to enhance the stress transmission effect.
金物は二方向の鉄骨梁に接合される端部の平板
部とこの平板部を中央部で直交して連結する連結
部とから全体的に十字状に製作され、連結部が縦
長の平板状に形成される。 The hardware is made into a cross shape as a whole, consisting of a flat plate part at the end that is joined to the steel beams in two directions, and a connecting part that connects the flat plate parts orthogonally at the center, and the connecting part is shaped like a vertically long flat plate. It is formed.
以下本考案を一実施例を示す図面に基づいて説
明する。
The present invention will be explained below based on the drawings showing one embodiment.
この考案の梁接合用金物１（以下金物１）は第
１図に示すように端部の二方向の平板部１ａ，１
ａとこれらを直交してつなぐ連結部１ｂ，１ｂと
から全体的に十字状に形成されるもので、コンク
リート柱２（以下柱２）に二方向に対向して接合
される鉄骨梁３，３間に跨つてこれらを同時に接
続するものである。 The beam joining hardware 1 (hereinafter referred to as hardware 1) of this invention has flat plate portions 1a, 1 in two directions at the end, as shown in FIG.
The steel beams 3, 3 are formed in a cross shape as a whole from a and connecting parts 1b, 1b that orthogonally connect these, and are joined to a concrete column 2 (hereinafter referred to as column 2) in two directions facing each other. These are connected simultaneously across the gap.
各平板部１ａには鉄骨梁３の規模に応じた複数
個のボルト孔１ｃが設けられ、ここにおいて金物
１は鉄骨梁３のフランジにボルト接合される。 Each flat plate portion 1a is provided with a plurality of bolt holes 1c corresponding to the scale of the steel beam 3, and the hardware 1 is bolted to the flange of the steel beam 3 here.
連結部１ｂは平板部１ａの面に対して垂直な面
をなすよう縦長の平板状に形成され、これによつ
て一方向の連結部１ｂはそれに直交する方向の平
板部１ａ，１ａからの引張力に対して支圧効果を
発揮することになる。 The connecting portion 1b is formed into a vertically long flat plate shape so as to form a plane perpendicular to the plane of the flat plate portion 1a, so that the connecting portion 1b in one direction can resist tension from the flat plate portions 1a, 1a in a direction perpendicular to the connecting portion 1b. This will exert a bearing effect against the force.
連結部１ｂはすなわちコンクリート中で支圧板

であればよく、第１図に示すような形状の他、第
２図−，，に示すような楕円形、長方形、
多角形等のさまざまな断面形状に製作可能であ
る。 Since the connecting portion 1b plays the role of a bearing plate in concrete, its shape may be approximately flat, and in addition to the shape shown in Figure 1, it may be oval as shown in Figure 2. , rectangle,
It can be manufactured into various cross-sectional shapes such as polygons.
第３図、第４図はこの金物１による柱２と鉄筋
梁３，３との接合例を示したものである。ここに
示すように金物１は柱２に二方向に対向する鉄骨
梁３，３間に跨設され、各フランジにボルトによ

り、は二列に設けたもので、比較的曲げモーメ
ントの大きい場合の使用例である。 In the embodiment shown in Fig. 3, there are bolt holes 1 in the flat plate part 1a.
c are provided in one row, which is an example of use when the bending moment acting on the steel beam 3 is relatively small, and is provided in two rows, which is an example of use when the bending moment is relatively large.
以上図面では金物の連結部１ｂを二列並列させ
た実施例を示しているが、この連結部１ｂの一方
向の列数は接合部に作用する応力を考慮して適宜
一列、もしくは複数列と調節される。 The drawings above show an embodiment in which two rows of hardware connecting portions 1b are arranged in parallel, but the number of rows in one direction of these connecting portions 1b may be one or more as appropriate, taking into consideration the stress acting on the joint. adjusted.

This idea is as described above. By making the shape cross-shaped and making the connection part a vertically long flat plate, this connection part exerts a bearing pressure effect, increasing the strength of the joint part, and as a result, the strength of the column is increased. It becomes possible to reduce the cross section and cost.
