Transition joint of basement beam-column-cap-free reserved hole and construction method of transition joint
The invention relates to the technical field of house buildings, and discloses a transition joint of a basement beam-column-cap-free reserved hole and a construction method thereof.The transition joint comprises a structural beam plate reserved hole and an opposite-jacking frame, and the opposite-jacking frame is arranged in the structural beam plate reserved hole; the opposite jacking frame comprises a main body structure, longitudinal supporting legs and transverse supporting legs, the longitudinal supporting legs and the transverse supporting legs are perpendicular to each other and horizontally extend to the outer side of the main body structure, and the longitudinal supporting legs and the transverse supporting legs perpendicularly abut against the inner wall of a reserved hole of a structural beam plate; shear keys and reserved steel bars are further arranged on the inner walls of the reserved holes of the structural beam plate, and the shear keys and the reserved steel bars horizontally extend to openings of the reserved holes of the structural beam plate. A structural beam plate reserved hole forms an integral closed structure, and the horizontal force transmission requirement is met by utilizing the strength, compression resistance and bending resistance characteristics of the top frame; the shear keys and the reserved steel bars can form good connection strength with the concrete, the weak shear-resistant link at the construction joint is reinforced, and the shear-resistant stress requirement is met.
本发明涉及房屋建筑技术领域，公开了一种地下室无梁柱帽预留洞口的过渡节点及其施工方法，包括结构梁板预留洞口和对顶架，对顶架布置在结构梁板预留洞口的内部；对顶架包括主体结构、纵向支脚和横向支脚，纵向支脚与横向支脚相互垂直且均水平延伸至主体结构的外侧，纵向支脚、横向支脚均垂直抵接在结构梁板预留洞口的内壁上；结构梁板预留洞口的各个内壁处还设置有抗剪键和预留钢筋，抗剪键以及预留钢筋均水平延伸至结构梁板预留洞口的口。结构梁板预留洞口形成整体封闭结构，利用对顶架的强度和抗压抗弯的特性满足水平传力要求；抗剪键和预留钢筋可以与混凝土形成良好的连接强度，对施工缝处抗剪薄弱环节进行加强处理，满足抗剪切受力要求。
