JIN SHUANGSHUANG / CAO ZHIJIE / BAI JIULIN / YANG JINGWEI

The invention relates to a modular unit frame column-column connecting joint and a house building system thereof. The modular unit frame column-column connecting joint comprises two frame side columns, a connecting steel plate frame used for horizontally connecting the frame side columns and embedded parts used for longitudinally connecting the frame side columns. The connecting steel plate frame comprises a long steel plate strip, short steel plate strips welded to the two ends of the long steel plate strip and a plurality of steel plate pieces longitudinally welded to the long steel plate strip and the short steel plate strips. The steel plate pieces are provided with corresponding through holes facilitating steel bar penetrating. Notches are formed in the end faces of the frame side columns and are in a shape similar to a Chinese character'ao ', and through grooves facilitating penetrating of the steel plate pieces are formed in the opposite sides of the frame side columns; a plurality of grouting holes are formed in the frame side columns; the problems that existing fabricated building columns are connected in a mechanical sleeve connection mode, a bolt connection mode, a welding mode and the like, connection construction is complex, the manual operation amount is large, the manual operation difficulty is large, and the construction efficiency is low are solved.

本发明涉及一种模块化单元框架柱‑柱连接节点及其房屋建筑体系，包括两根框架边柱、用于水平连接框架边柱的连接钢板架和用于纵向连接框架边柱的预埋件；连接钢板架包括长钢板条、焊接在长钢板条两端端部的短钢板条以及纵向焊接在长钢板条、短钢板条上的若干钢板片，钢板片上开设有相对应且便于穿设钢筋的通孔；框架边柱的端面开设有缺口且呈类凹字形，框架边柱相对一侧开设有便于钢板片穿过的通槽；框架边柱上开设有若干注浆孔；解决目前装配式建筑柱柱连接采用机械套筒连接、螺栓连接和焊接等方式，连接施工复杂，人工操作量大难度大，施工效率较低的问题。
