Bunching barrel structure for large vertical height concrete pouring construction

SUN PENG / LIU HUAPU / ZHANG YONGQI

The invention relates to the technical field of building construction, in particular to a string barrel structure for large vertical height concrete pouring construction, which comprises a plurality of metal barrels which are detachably connected in sequence and are gradually reduced in barrel diameter from top to bottom, and is characterized in that a plurality of radially extending convex blocks are circumferentially arranged on the inner wall of the top end of each metal barrel at equal intervals; a connecting plate with a material hole pre-formed in a plate body is hung at the bottom of the metal cylinder, a sleeve is integrally arranged on the periphery of the material hole on the bottom surface of the connecting plate, and a plurality of slots for inserting the corresponding lugs are formed in the cylinder wall at the bottom of the sleeve; and an extension cylinder made of a flexible material is integrally arranged at the bottom end of the metal cylinder and is in transition connection with the hole wall of the material hole. The metal cylinders are connected stably, angle adjustment and temporary fixation can be carried out according to the construction environment, meanwhile, the segregation phenomenon of concrete is further reduced, and the construction efficiency and the construction quality are improved.

本发明涉及建筑施工技术领域，尤其涉及一种大垂直高度混凝土浇筑施工用串桶结构，包括数个顺次可拆卸连接且自身呈由上至下筒径递减的金属筒，其特征在于,所述金属筒顶端内壁周向等间距设有数个径向延伸的凸块，金属筒底部吊装有板体上预开设料孔的连接板，连接板底面于料孔外周一体设有套筒，套筒底部筒壁上开设有数个用于插配对应凸块的插槽；所述金属筒底端一体设有柔性材质制成的延展筒，延展筒与料孔孔壁过渡连接。本发明的金属筒之间连接稳定且可以根据施工环境进行角度调节和暂时性固定，同时进一步降低了混凝土的离析现象，提高施工效率和施工质量。
