Portable connecting structure for prefabricated column and steel beam
The invention discloses a portable connecting structure for a prefabricated column and a steel beam. The portable connecting structure comprises the prefabricated column; a plurality of fan-shaped encircling sleeves arranged on the periphery of the prefabricated column form an assembly type steel encircling sleeve, concrete pouring is carried out in the assembly type steel encircling sleeve after the prefabricated column and a steel beam are connected through the assembly type steel encircling sleeve, an end plate is installed between every two adjacent fan-shaped encircling sleeves, and the interior of the prefabricated column further comprises an inner supporting steel pipe. The fan-shaped surrounding sleeve comprises an upper flange plate and a lower flange plate which are arranged at the two ends of the fan-shaped surrounding sleeve, the radial length of the upper flange plate and the radial length of the lower flange plate are smaller than 500 mm, and the thickness of the upper flange plate and the thickness of the lower flange plate are larger than or equal to the thickness of flanges of the corresponding steel beams. The joint can be used for connection when beams are different in height, and the fan-shaped steel enclosure effectively moves the plastic hinge to the beams outwards while improving the connection strength, so that the joint is effectively protected, brittle failure of the joint is avoided, and the anti-seismic property can be improved.
本发明公开了一种预制柱与钢梁便携式连接结构，包括：预制柱；设置在所述预制柱外周的若干扇形围套形成装配式钢围套，以通过所述装配式钢围套将所述预制柱与钢梁进行连接后在所述装配式钢围套内进行混凝土浇筑，其中，相邻两个扇形围套之间安装有端板，所述预制柱内部还包括内支撑钢管；所述扇形围套包括设置在扇形围套两端的上翼缘板、下翼缘板，所述上翼缘板和所述下翼缘板的径向长度小于500mm，且所述上翼缘板和所述下翼缘板的厚度大于或等于对应钢梁的翼缘厚度。本发明能够用于不同梁高时的连接，扇形钢围套在提高连接强度的同时，有效的将塑性铰外移到梁上，从而有效地保护节点，避免其发生脆性破坏，并且能提高抗震性能。
