Node structure of retard-bonded prestressed beam and steel reinforced concrete column
The invention discloses a joint structure of a retard-bonded prestressed beam and a steel reinforced concrete column, which comprises the steel reinforced concrete column, a concrete column cap, a prestressed concrete beam, a concrete beam haunch, retard-bonded prestressed steel bars and steel bar connecting plates, the concrete column cap is arranged at the top of the steel reinforced concrete column, the prestressed concrete beam is connected with the concrete column cap and the steel reinforced concrete column, and the concrete beam haunch is arranged at the beam end of the prestressed concrete beam. The retard-bonded prestressed tendons are adopted, tensioning can be conducted on the beam top close to the beam-column joint in batches, haunching tensioning ends do not need to be arranged on the two sides of the beam, and the effect of saving the using amount of concrete is achieved. The beam end haunching enables prestressed steel bars and part of common steel bars to be capable of bypassing the section steel column in the steel reinforced concrete main body, the strength of the joint can be better guaranteed, and the design concept of'strong joint and weak component 'is achieved.
本发明公开了一种缓粘结预应力梁与型钢混凝土柱的节点构造，包括：型钢混凝土柱、混凝土柱帽、预应力混凝土梁、混凝土梁加腋、缓粘结预应力钢筋、钢筋连接板，所述型钢混凝土柱的翼缘上焊接有钢筋连接板，所述混凝土柱帽设置在型钢混凝土柱的顶部，所述预应力混凝土梁与混凝土柱帽和型钢混凝土柱相连接，所述混凝土梁加腋设置于预应力混凝土梁的梁端。本发明采用缓粘结预应力筋，可以在紧邻梁柱节点处的梁顶分批张拉，不需要在梁两侧设置加腋张拉端，达到节省混凝土用量的效果。梁端加腋一起使得预应力钢筋及部分普通钢筋均可以绕过型钢混凝土主内的型钢柱，更能保证节点的强度，达到“强节点弱构件”的设计理念。
