Such as Fig. 1 and Fig. 2, the utility model provides a kind of buckling-restrained support and the board-like anchor connection node of beam column built from concrete T-steel, comprise the node plate 3 being anchored in beams of concrete 1 and coagulation earth pillar 2 node place, node plate 3 has the first part 31 being anchored in beams of concrete 1 and coagulation earth pillar 2 and the second section 32 being positioned at outside beams of concrete 1 and coagulation earth pillar 2, the positive and negative surface of first part 31 is symmetrically welded with multiple T-steel group, and second section 32 is provided with for the threaded hole 6 that buckling-restrained support is fixedly connected with. Liang Zhuzhong has buried T-steel group and node plate 3 in advance, add the steel ratio of node region, therefore the strength and stiffness of node are obtained for lifting, and node plate 3 retrains the viscous deformation of beam post to a certain extent, the position making beam may occur that plasticity is twisted is shifted in girder span by beam-ends, it is very beneficial for the principle of design of " strong node, weak rod member ".
Such as Fig. 1 and Fig. 2, T-steel group comprises the first T-steel group 4 being positioned at beams of concrete 1 and the 2nd T-steel group 5 being positioned at coagulation earth pillar 2, first T-steel group 4 has three the first T-steels 41 and lines up two rows, upper row has two the first T-steels 41, lower row has one, there is interval in three the first T-steels 41, the row making the setting of the first T-steel 41 can not affect reinforcing bar in beams of concrete 1 establishes each other. The steel rib 412 that each first T-steel 41 has the steel wing 411 being positioned at top and extends downwards in the middle part of the described steel wing 411, both form T-shaped jointly, three the first T-steels 41 form acute triangle, the described steel rib 412 of the first T-steel 41 points to the inside of acute triangle, namely the steel rib 412 of upper row points to lower section, and the steel rib 412 of lower row points to top, and two row's steel ribs are oppositely arranged, make the framework shape triangulation in beams of concrete 1, more firmly. Above-mentioned acute triangle preferably equilateral triangle, makes the uniform force of three T-steels. This kind of arrangement mode can make the uniform power transmission of node plate 3 to beams of concrete 1, ensures node plate 3 stability under loading.
2nd T-steel group has three the 2nd T-steels 51 and forms a line, 2nd T-steel 51 is identical with the structure of the first T-steel 41, the steel wing 411 of three the 2nd T-steels 51 is parallel to each other and not in same plane, steel rib 412 points to the same side, all point to lower section, namely the steel wing 411 is horizontally disposed with, and steel rib 412 is vertically arranged.
