Construct for buildings and a method for manufacturing the same

A construct for buildings comprising an elongated steel pipe member with a hollow interior and reinforcing elements provided in a hollow portion of the interior of the steel pipe member to cross the interior of the steel pipe member in a longitudinal direction, said steel pipe member and said reinforcing elements being welded and joined together at a plurality of joint holes piercingly formed on an outer peripheral portion of said steel pipe member,

• wherein said steel pipe member is formed with inserting holes for the reinforcing elements on the outer peripheral portion of the steel pipe member formed at mounting positions for said reinforcing elements to be of a width that meets a width dimension of the reinforcing elements,
• wherein these inserting holes are provided to be successive from the outer peripheral surface of said steel pipe member to said interior,
• wherein said reinforcing elements are inserted into the inserting holes from the outer peripheral surface of said steel pipe member towards a direction facing the interior of the steel pipe member in a direction that is substantially orthogonal to the longitudinal direction of the steel pipe member,
• wherein said reinforcing elements are formed to be plate-like, to have side surfaces that are smaller than cross sections crossing the hollow portion in the interior of the steel pipe member, and to have an outer peripheral surface that is substantially orthogonal to the side surfaces and that corresponds to an inner wall surface of said steel pipe member,
• wherein an engaging element for engaging with suspending means that suspends the reinforcing elements is provided on one side portion of said outer peripheral surface,
• wherein projecting members corresponding to the joint holes piercingly formed on the outer peripheral portion of said steel pipe member are formed on the outer peripheral surface of said reinforcing element on a side opposite to the engaging element,
• wherein the engaging elements of the reinforcing elements are provided to be parallel to the longitudinal direction of the outer peripheral surfaces of the reinforcing elements,
• wherein engaging members for engaging engaging elements of the suspending means are respectively provided on both side portions in the longitudinal direction,
• wherein the engaging members comprise sloped surfaces that arise from above the outer peripheral surface of said reinforcing element and that respectively become broader in both outer directions in the longitudinal direction of the outer peripheral surface of said reinforcing element, and
• wherein a shape that sections in a direction orthogonal to the longitudinal direction of the reinforcing element is formed on an upper portion of said engaging element to be triangular, arc-like or quadrangular.

• wherein these inserting holes are provided to be successive from the outer peripheral surface of said steel pipe member to said interior,
• wherein said reinforcing elements are inserted into said inserting holes from the outer peripheral surface of said steel pipe member towards a direction facing the interior of said steel pipe member in a direction that is substantially orthogonal to the longitudinal direction of the steel pipe member,
• wherein guiding elements are prepared separately and provided in underneath joint holes piercingly formed on the outer peripheral portion of said steel pipe member,
• wherein each of the guiding elements comprises stopping members that abut inner walls of said joint hole and guide members that extend from the stopping members and that jut into a space portion of said steel pipe member, and
• wherein the guide members comprise sloped surfaces that expand to both sides with respect to a length direction of said steel pipe member with said joint holes so that a lower end edge portion of the reinforcing element enters.

A method for manufacturing a construct for buildings, wherein in a construct for buildings comprising an elongated steel pipe member with a hollow interior and reinforcing elements provided in a hollow portion of the interior of the steel pipe member to cross the interior of the steel pipe member in a longitudinal direction, said steel pipe member and said reinforcing elements are welded and joined together at a plurality of joint holes piercingly formed on an outer peripheral portion of said steel pipe member,

• wherein inserting holes are piercingly formed at mounting positions for said reinforcing elements on the outer peripheral portion of said steel pipe member and the steel pipe member is mounted in a substantially horizontal manner such that said inserting holes face upward,
• wherein engaging elements formed on upper portions of the reinforcing elements are suspended by a suspending means above the inserting holes such that outer peripheral portions that comprise width directions of the reinforcing elements face downward, the reinforcing elements being descended into the inserting holes by dropping the same in a vertical manner through own weight of the reinforcing members and inserted in a direction substantially orthogonal to the longitudinal direction of the steel pipe member from the outer peripheral surface of said steel pipe member towards the interior of said steel pipe member,
• wherein downside outer peripheral surfaces of said reinforcing elements are supported and received by a lower inner surface of the hollow portion of said steel pipe member such that the outer peripheral surfaces on both side portions of the reinforcing elements correspond to inner side surfaces of the hollow portion of the steel pipe member, and
• wherein said steel pipe member and the outer peripheral portions of said reinforcing elements are welded and joined to become integral at the inserting holes and said plurality of joint holes.
