よい型鋼を提供することを目的とする。[Detailed description of the invention] This invention relates to a shaped steel used for reinforcing panels of concrete formwork. Shaped steel can be assembled by attaching a round or square pipe to the inside of a rectangular or oval opening that continues in the longitudinal direction using a tightening fitting, and attaching other shaped steel to the pipe in the same way, for reinforcing panels of concrete formwork, etc. It was used for. The shaped steel is generally formed by facing two side walls each having a plurality of continuous openings in the longitudinal direction, and connecting the side walls using a connecting member after the openings are substantially aligned. As a connecting member, the cut-and-raised piece used when forming the opening in the side wall was bent at an angle of about 90 degrees to the side wall surface, or a connecting member made of a separate member was used. Because of the insistence on matching the parts, the connecting end of the connecting part was not exposed inside the opening, and it was impossible to connect the side walls with spot welding, which is easy to work with when connecting the connecting pieces. . However, the inventor believes that when a round pipe, etc. is attached to a shaped steel, the opening edges of both side walls must match.
It was found that there is no difference in the workability and strength when installing the pipe even if the edges in the longitudinal direction of the opening in the side wall do not match, since the edge is parallel to the longitudinal direction to which a square pipe, etc. must be attached. This invention is based on the above knowledge, that is, in a shaped steel in which side walls having consecutive openings in the longitudinal direction face each other and the side walls are connected to each other at a connecting part, the corresponding openings in the side walls are arranged in the longitudinal direction. The connecting portion is bent from the longitudinal opening edge of the opening of one side wall toward the other connecting side wall, and from the position where it hits the inside of the other side wall, it is bent along the inside of the side wall toward the center of the opening. The object of the present invention is to provide a shaped steel that can be connected by spot welding and has good connection efficiency by providing a shaped steel that is bent to form a connecting end and fixed to the inside of the connecting end and the other side wall. .

を各々側壁２の内側と溶接して行なう。 1 is a shaped steel. The shaped steel 1 consists of two side walls 2 that have a pentagonal opening 3 extending in the longitudinal direction, and a connecting portion 4 that connects the side walls 2. As shown in FIG. 7, the side walls 2 have a substantially U-shaped cross section, and are connected back to back at a connecting portion 4. In this embodiment, the connecting portion 4 is made of a separate material from the side wall 2, and is shown in FIGS. 3 and 5.
As shown in the figure, both connecting ends 5, 5 in the cross-sectional shape
are bent in opposite directions, that is, one end of the connecting end faces toward the opening 3, while the other end faces toward the opposite side from the opening 3. The connecting portion 4 may be made of a cut and raised piece. When connecting the side walls 2, 2, as shown in FIG.
Approximately 1/10 of the opening length in the longitudinal direction of opening 3 on both side walls
Shift them by ~1/8, but connect them so that the pentagonal point of the opening does not shadow the other side wall. The connection by the connecting part 4 is performed by aligning the center part of the connecting part 4 with the inner edge of one side wall, and connecting the connecting ends 5, 5.
are welded to the inside of the side wall 2, respectively.
即ち、連結部の一の連結端５を、一の側壁２の
開口部の長手方向開口縁内側に固定し、連結する
他方の側壁２方向に連結部４の中央部を折曲し、
他方の側壁２の内側に当つた位置から側壁内側に
そつて開口部中心方向に折曲して他端の連結端５
を形成し、この連結端と他方の側壁２の長手方向
内口縁内側とを溶接する。 That is, one connecting end 5 of the connecting part is fixed inside the longitudinal opening edge of the opening of one side wall 2, and the central part of the connecting part 4 is bent in the direction of the other side wall 2 to be connected.
From the position where it hits the inside of the other side wall 2, bend it along the inside of the side wall toward the center of the opening and connect the connecting end 5 at the other end.
This connecting end is welded to the inner side of the inner mouth edge in the longitudinal direction of the other side wall 2.
このとき、連結端の一端は、側壁２の開口部が
ずれているため、開口部内側に露出しており、そ
のためスポツト溶接により連結することが可能で
ある。 At this time, since the opening of the side wall 2 is shifted, one end of the connecting end is exposed inside the opening, and therefore it is possible to connect by spot welding.
従つて、この考案では、組立て効率がよく、強
度的に変わりがなく、丸パイプ等パイプ材の取付
けに支障のない型鋼を提供することが可能であ
る。 Therefore, with this invention, it is possible to provide a shaped steel with good assembly efficiency, no change in strength, and no problem in attaching pipe materials such as round pipes.
