Title
(EN) PRECAST COLUMN BASE JOINT AND CONSTRUCTION METHOD THEREFOR
(FR) JOINT DE BASE DE COLONNE PRÉCOULÉE ET SON PROCÉDÉ DE CONSTRUCTION
(ZH) 一种装配式柱脚连接节点及其施工方法
Abstract
(EN) A precast column base joint, comprising an upper prefabricated reinforced concrete column (1), a lower reinforced concrete foundation (2), column anchoring longitudinal ribs (3), grouting sleeves (4), and foundation anchoring reinforcing bars (6) that are correspondingly combined in a vertical direction. The foundation anchoring reinforcing bars (6) and the column anchoring longitudinal ribs (3) are connected by means of a seam filling material (7) with which the grouting sleeves (4) are filled; the seam between the reinforced concrete foundation (2) and the prefabricated reinforced concrete column (1) is also filled with the seam filling material (7); each of the foundation anchoring reinforcing bars (6) comprises a vertical part (8) and a horizontal part (9); the vertical part (8) is divided into an upper anchoring section (81) extending out of the upper surface of the reinforced concrete foundation (2), and a central unbonded section (82) and a lower anchoring section (83) embedded in the reinforced concrete foundation (2); an isolation sleeve (10) used for isolating the central unbonded section (82) from concrete is provided on the central unbonded section (82); the top surface of the isolation sleeve (10) is flush with the upper surface of the reinforced concrete foundation (2). Also provided is a construction method for a precast column base joint.
(FR) L'invention concerne un joint de base de colonne précoulée, comprenant une colonne de béton armé préfabriquée supérieure (1), une fondation en béton armé inférieure (2), des nervures longitudinales d'ancrage de colonne (3), des manchons de cimentation (4), et des barres d'armature d'ancrage de fondation (6) qui sont combinées en correspondance dans une direction verticale. Les barres d'armature d'ancrage de fondation (6) et les nervures longitudinales d'ancrage de colonne (3) sont reliées au moyen d'un matériau de remplissage de couture (7) avec lequel les manchons d'injection (4) sont remplis ; la couture entre la fondation en béton armé (2) et la colonne de béton armé préfabriquée (1) est également remplie à l'aide du matériau de remplissage de couture (7) ; chacune des barres d'armature d'ancrage de fondation (6) comprend une partie verticale (8) et une partie horizontale (9) ; la partie verticale (8) est divisée en une section d'ancrage supérieure (81) s'étendant hors de la surface supérieure de la fondation en béton armé (2), et une section non liée centrale (82) et une section d'ancrage inférieure (83) incorporées dans la fondation en béton armé (2) ; un manchon d'isolation (10) servant à isoler la section non liée centrale (82) du béton est prévu sur la section non liée centrale (82) ; la surface supérieure du manchon d'isolation (10) est en affleurement avec la surface supérieure de la fondation en béton armé (2). L'invention concerne également un procédé de construction d'un joint de base de colonne précoulée.
(ZH) 一种装配式柱脚连接节点,包括竖向对应拼接的上部的预制钢筋混凝土柱(1)、下部钢筋混凝土基础(2)、柱锚固纵筋(3)、灌浆套筒(4)、基础锚固钢筋(6),基础锚固钢筋(6)与柱锚固纵筋(3)通过灌浆套筒(4)内充满的灌缝材料(7)连接,钢筋混凝土基础(2)和预制钢筋混凝土柱(1)拼接缝处也充满有灌缝材料(7),基础锚固钢筋(6)包括竖部(8)和水平部(9),竖部(8)分为伸出钢筋混凝土基础(2)的上表面的上部锚固段(81)、埋入钢筋混凝土基础(2)内的中部无粘结段(82)和下部锚固段(83),中部无粘结段(82)的外部设有隔离其与混凝土粘结的隔离套件(10),隔离套件(10)的顶面与钢筋混凝土基础(2)的上表面平齐。还提供了一种装配式柱脚连接节点的施工方法。
