Assembly beams are mainly used as large beams that support large loads.
Generally, it is assembled so that its cross section is T-shaped or T-shaped.

体が大型化する難点がある。"Problems to be Solved by the Invention" By the way, it goes without saying that beams are required to have strength depending on the location where they are applied, but the above-mentioned single beams, assembled beams, etc. are mainly made of steel. There is a limit to the strength (particularly the compressive strength in the longitudinal direction) depending on the cross-sectional shape, cross-sectional area, etc. Also, although beams with a steel-framed concrete structure have superior compressive strength compared to beams made only of steel, they have the disadvantage of increasing the size of the beam as a whole.
本発明は上記の事情に鑑みてなされたもので、その目的
とするところは、圧縮力に対する梁強度の向上ならびに
軽量化を実現する全く新しい梁（充填鋼管コンクリート
梁）を提供することにある。The present invention has been made in view of the above circumstances, and its purpose is to provide a completely new beam (filled steel pipe concrete beam) that achieves improved beam strength against compressive force and reduced weight.

形を吸収する変形吸収部を設けたものである。"Means for Solving the Problems" In order to achieve the above object, the beam of the present invention has a steel pipe fixed to one side edge of the web constituting a part of the beam. The inside of the steel pipe is filled with concrete, and a separation layer is provided between the steel pipe and the concrete to keep them in a non-adherent state. A deformation absorbing portion that absorbs deformation in the axial direction is provided in part.

クリートとが、分離層の作用で互いに軸方向にずれ合い
ながら別々に変位する。"Action J" When the filled steel pipe concrete beam of the present invention is placed horizontally between architectural columns, etc. with the steel pipe side up, a compressive force in the tube axis direction mainly acts on the upper part of the beam. At this time, the steel pipe and the concrete are displaced separately while being shifted in the axial direction from each other due to the action of the separation layer.

得られる。In a steel pipe, most of the strain that should occur throughout the tube is absorbed by the deformation absorbing portion, and the amount of strain and stress in the axial direction becomes zero in other portions. In addition, in the case of concrete, since the concrete 1 supports substantially all of the compressive load, distortion and stress occur throughout the concrete. Therefore, a confining effect is obtained in which the steel pipe resists the radially outward displacement of the concrete and tightens the concrete radially inwardly.

フランジ（ｊＩｉＩｉ板）３が溶接固定されている。The web I is constructed by diagonally arranging steel materials such as steel rods and narrow steel plates in a truss shape, and as a whole extends in the direction of the arrow in FIG. Here, for convenience, if we consider the web I as a band-shaped part including the spaces between each scrap material,
A steel pipe 2 is welded and fixed to one side edge of the web l (the upper edge in FIG. 1) along this negative side edge, and a steel pipe 2 is welded and fixed to the other side edge (lower side edge) along this side edge. A strip-shaped flange (jIiIi plate) 3 that is substantially perpendicular to the web is fixed by welding.

That is, in this embodiment, the portion having the long holes 4 serves as the deformation absorbing portion 5. Further, a separation layer 6 is provided on the inner surface of the steel pipe 2, and this separation layer 6
The inside of the steel pipe 2 is filled with concrete 7 via. The separation layer 6 is, for example, a layer of paraffin, grease, asphalt, or plastic, and serves to maintain the steel pipe 2 and the concrete 7 in an unbonded state (non-adhesive state).

That is, the steel pipe 2 resists the radially outward displacement of the concrete 7 at this time and tightens the concrete 7 radially inward. Therefore,
Due to this action of the steel pipe 2 (so-called confine effect), the upper part of the beam exhibits excellent compressive strength.

ができろ。When this filled steel pipe concrete beam is placed horizontally between columns with the steel pipe side up, when compressive force is applied to the top of the beam in the tube axis direction, the concrete will be displaced radially outward. , a confining effect is obtained in which the steel pipe resists and tightens the concrete radially inward. In other words, since the upper part of the beam has excellent compressive strength, the beam as a whole can be made smaller by having a smaller cross-sectional area compared to conventional beams, while still maintaining the same or higher strength than conventional beams. Be able to do it.
