め前記の問題は残る。By the way, the inventors previously developed a structure in which two shaped steels are arranged in parallel. (Actual exploitation 59-28102) The steel beam that assembles these two shaped steels in parallel makes it possible to construct a frame with a larger span by increasing bending strength, but the above problems remain because the rigidity cannot be increased. .
梁の振動等の障害は鉄骨梁に特有の現象であり、これ

を解消しようとするものである。This invention was made for the purpose of synthesizing a steel frame beam and a reinforced concrete beam so that both of them bear the total load and increase the rigidity while maintaining the proof stress.
Although a structure as shown in Japanese Patent No. 27111 has been proposed, the present invention is intended to facilitate the work of arranging and to integrate a steel beam and a reinforced concrete beam. At the same time as making the most of its characteristics, it aims to eliminate the difficulties peculiar to steel beams.

Between the steel bars of a steel beam made of a book-shaped steel, the main reinforcing bars and the shape and shape of the reinforcing bars surrounding the main reinforcing bars whose bases are fixed to the webs of the structural steels are projected, and the bending tip of the reinforcing bars is Reinforced concrete beams by arranging beam reinforcements consisting of many ribs so as to form a □ shape when viewed in the longitudinal direction and arranging main reinforcing bars at the inner corners of the □ ribs and placing concrete And a reinforcing steel-framed reinforced concrete beam, wherein the steel beam and the reinforced concrete beam bear the entire load.
以下この発明を図面に基づいて説明する。 The present invention will be described below with reference to the drawings.
この発明の鉄骨鉄筋コンクリート梁は主として２本の
鉄骨梁１、１とこの間に打設構成される鉄筋コンクリー
ト梁２とからなる。使用される形鋼１はＨ形鋼か溝形鋼
が適当である。The steel-framed reinforced concrete beam of the present invention mainly comprises two steel-framed beams 1 and 1 and a reinforced concrete beam 2 placed between them. The section steel 1 used is preferably an H-section steel or a channel steel.

ジ間に架渡してもよい。At the time of construction, a fixed gap is provided between the upper flanges, a form 3 is provided between the lower flanges, and the webs are assembled so that they are parallel to each other at regular intervals. It may be arranged and poured with concrete, and as the formwork 3, a lower flange and a thick plate may be attached or a thin plate may be bridged between the flanges.

筋４は剪断補強鉄筋となり、コンクリートを打設して鉄
筋コンクリート梁としたものである。第２図、第３図は
同様に鉄骨梁１として溝形鋼を使用した場合を示す。Fig. 1 shows the case where H-shaped steel is used as the steel beam 1, and each web is provided with projecting shape and shape rebar surrounding the main rebar having the base fixed, and the bent tip of the rebar is arranged in the length direction of the beam. A large number of ribs 4 are arranged so as to form a square shape, and the main rebars 5 are inserted through the inner corners of the square ribs 4 so that the ribs 4 become shear reinforcement bars. It is a reinforced concrete beam made by placing concrete. Similarly, FIGS. 2 and 3 show the case where channel steel is used as the steel beam 1.
こうして構成された鉄骨梁の剛性、耐力をＨ形鋼２本
からなる鉄骨梁と比較すると、剛性に関しては、鉄筋コ
ンクリートにより補強された鉄骨梁は、補強のない鉄骨
梁に比べ、約２倍の曲げ剛性を有し、耐力については、
従来の鉄骨鉄筋コンクリート梁より20〜30％、補強のな
い鉄骨梁より約40％曲げ耐力の増加が見られる。Comparing the rigidity and proof stress of the steel beam constructed in this way with the steel beam composed of two H-shaped steels, in terms of rigidity, the steel beam reinforced by reinforced concrete is about twice as bent as the steel beam without reinforcement. It has rigidity and yield strength
The bending strength is increased by 20 to 30% compared to conventional steel reinforced concrete beams and about 40% compared to steel beams without reinforcement.

結果鉄骨梁のみの場合の難点である振動、たわみは解消
される。In this way, each web of a steel beam made of two shaped steels is provided with a projecting shape and a bar around the main reinforcing bar having a fixed base, and the bent tip of the reinforcing bar is seen as a □ shape when viewed in the length direction of the beam. A large number of ribs are laid out so that the main rebars are inserted through the inner corners of the □ -shaped ribs so that the rebar work is easy, and there are no gaps between the steel beams of the steel beams. It is possible to significantly increase both rigidity and proof stress by connecting the reinforced concrete beams integrally with each other and connecting them with the provided ribs. As a result, the vibration and flexure, which are the problems when only steel beams are used, are eliminated.
また、ほぼ同じ鉄骨重量、梁せいの鉄骨鉄筋コンクリ
ート梁に対して耐力で勝り、それだけ断面梁せいを小さ
くできるので、材料の節約につながると同時に、階高を
減ずることができる。Moreover, since it is superior in proof strength to a steel-framed reinforced concrete beam having almost the same steel frame weight and beam, and the beam cross-section can be made smaller by that much, the material can be saved and the floor height can be reduced.
さらに、梁の側型枠が不要になることで鉄骨鉄筋コン
クリート梁より施工が容易になる他、梁内部のコンクリ
ートのまわりを心配する必要はない。Furthermore, since the side formwork of the beam is not required, the construction is easier than that of the steel-framed reinforced concrete beam, and there is no need to worry about the surrounding concrete inside the beam.
