Beam column joint for reverse construction method foundation pit engineering

ZHOU WEN / CHEN JING / XU XINYU / SUN YUYONG

The invention provides a beam-column joint for reverse construction method foundation pit engineering, which comprises a beam-column base body assembly and a joint mechanism, the beam-column base body assembly comprises a steel pipe column, a primary pouring body and a secondary pouring body; the node mechanism comprises a plurality of connecting bases, a plurality of flange plates, a plurality of node connectors, a through hole, a plurality of sliding grooves, a plurality of connecting parts and a plurality of inserting grooves. The steel pipe column is arranged at the top of the primary pouring body; according to the beam column joint, the through holes and the sliding grooves are formed so that the joint connector and the flange plate can stretch out of the steel pipe column, and then the flange plate is used for conducting flange connection between the connecting base and the joint connector so that the beam column joint can be fixedly installed on the steel pipe column in a beam column; and then concrete is poured in the steel pipe column and outside the steel pipe column in sequence to form a secondary pouring body, so that the beam column joint is fixedly installed in the beam column, the loading force and the shearing resistance between the beam column joint and the beam column are improved, and the stability between the beam column joint and the beam column is guaranteed.

本发明提供了一种用于逆作法基坑工程的梁柱节点，包括梁柱基体组件和节点机构，所述梁柱基体组件包括钢管柱、一次浇注体和二次浇注体；所述节点机构包括若干连接座、若干法兰盘、若干节点接头、通孔、若干滑槽、若干连接部和若干插槽；所述钢管柱设于所述一次浇注体的顶部；本发明通过设置的通孔和滑槽以便将节点接头和法兰盘从钢管柱内伸出，然后通过利用法兰盘对连接座和节点接头之间进行法兰连接，用以将梁柱节点安装固定在梁柱内部的钢管柱上，然后依次将混凝土浇注在钢管柱内和钢管柱外形成二次浇注体，从而将梁柱节点安装固定在梁柱内部，提高了梁柱节点与梁柱之间的荷载力及抗剪力，保证了梁柱节点与梁柱之间的稳定性。
