Assembly type concrete beam column inserted bolt splicing joint and manufacturing construction method

DING GUANGFU

The invention discloses an assembly type concrete beam column inserted bolt splicing joint and a manufacturing construction method. The splicing joint comprises a concrete prefabricated beam, a column, a beam column connector and a plurality of fasteners, wherein the two ends of the beam column connector and the concrete prefabricated column form a mortise and tenon joint structure; the beam column connector and a prefabricated superposed beam are quickly spliced through a connecting plate; and all connecting parts are fixedly connected through the fasteners. Splicing of the large-eccentric pressed prefabricated beam column is achieved in a dry connection mode, great convenience is brought to installation while the fracture resistance of the connecting part of the prefabricated beam columnis enhanced, the construction efficiency is improved, the construction safety is high, and the cost is relatively low. The beam column connector is independently arranged, the beam column connectingdirection does not need to be considered, the beam column with the required length is prefabricated in a factory in a unified mode, rapid assembly can be achieved on site, batch large-scale productioncan be achieved conveniently, and the production efficiency and the installation convenience are effectively improved.

本发明公开了一种装配式混凝土梁柱插入式螺栓拼接节点及制作施工方法，该拼接节点包括混凝土预制梁、柱，梁柱连接头和若干紧固件，梁柱连接头两端和混凝土预制柱形成榫卯结构，梁柱连接头和预制叠合梁通过连接板快速拼接，各连接部位通过紧固件固定连接，以干式连接方式实现大偏心受压预制梁柱的拼接，在增强预制梁柱连接部分抗折性能的同时，也给安装带来很大的便利性，提高施工效率，施工安全性较高，成本相对较低。其中梁柱连接头独立设置，无需考虑梁柱连接方向，在工厂统一预制所需长度的梁柱，即可在现场快速组装，便于实现批量化规模化生产，有效提高了生产高效性和安装便捷性。
