UPPER COLUMN OF BUILT-UP CONCRETE COLUMN, FORM FOR UPPER COLUMN FORMING, AND MANUFACTURING METHOD OF UPPER COLUMN OF BUILT-UP CONCRETE COLUMN
To provide an upper column of a built-up concrete column easy to manufacture and capable of suppressing lowering of strength with time, a form for upper column forming, and a manufacturing method of the upper column of the built-up concrete column.SOLUTION: An upper column 1 has: a cylindrical concrete part 3; a joint pipe 4 integrally arranged at one end part of the concrete part 3; a seat plate 5 fixed to the inside of the joint pipe 4; and a tendon 6 with the end part fixed to the seat plate 5 and buried in the concrete part 3. The joint pipe 4 has a cylindrical body part 10 with a lower column inserted into one end part, and a cylindrical reinforcing part 11 having one end part fixed to the inside of the other end part of the body part 10, and having the other end part projected beyond the other end part of the body part 10. The concrete part 3 has: an integrated part 8 formed from the inside of the joint pipe 4 over the seat plate 5; and a projection 9 projected from the other end part of the joint pipe 4 and formed flush with an outer face of the reinforcing part 11, or projecting outward from the outer face.SELECTED DRAWING: Figure 1
【課題】製造が容易で、かつ、経時的な強度の低下を抑制できる組立式コンクリート柱の上柱、上柱成形用型枠、および、組立式コンクリート柱の上柱の製造方法を提供する。【解決手段】上柱１は、筒状のコンクリート部３と、コンクリート部３の一端部に一体的に配置された継手管４と、継手管４の内部に固着された座板５と、座板５に端部が固定されてコンクリート部３に埋設された緊張材６と、を備える。継手管４は、下柱が一端部に挿入される筒状の本体部１０と、本体部１０の他端部の内側に一端部が固定され、他端部が本体部１０の他端部よりも突出する筒状の補強部１１と、を有する。コンクリート部３は、継手管４の内側から座板５に亘り形成された一体部８と、継手管４の他端部から突出し外面が補強部１１の外面と面一に、または、外面より外方に突出して形成された突出部９と、を有する。【選択図】図１
