Punching-resistant reinforced concrete slab column joint

SHI QINGXUAN / ZHAO WANGHU / JIANG MINGYUE

The invention discloses an anti-punching reinforced concrete plate column joint, and belongs to the field of building structures. Compared with traditional bent reinforcing steel bars, stirrups and anchor bolts, the perforated steel plate is a continuous body on the punching damage face of the reinforced concrete plate column joint, the perforated steel plate penetrates through the whole punching crack, the perforated steel plate can be fully stressed, cracking of concrete is relieved, the punching resistance of the perforated steel plate can be more efficiently exerted, and the service life of the perforated steel plate is prolonged. And the punching bearing capacity of the reinforced concrete slab column joint can be obviously improved. The structure is simple, installation is convenient, installation does not interfere with the tension reinforcing mesh and the compression reinforcing mesh, positioning is easy, prefabrication in a factory can be carried out in advance, the construction period is shortened, and the punching resistance of the reinforced concrete plate column joint is effectively improved.

本发明公开了一种抗冲切的钢筋混凝土板柱节点，属于建筑结构领域。相比于传统的弯起钢筋，箍筋，锚栓，开孔钢板在钢筋混凝土板柱节点的冲切破坏面上为连续体，开孔钢板贯穿整个冲切裂缝，开孔钢板能够充分受力，减缓混凝土的开裂，能够更高效的发挥其抗冲切性能，能够显著提高钢筋混凝土板柱节点的抗冲切承载力。本发明构造简单，安装方便，安装不会对受拉钢筋网和受压钢筋网造成干扰，易于定位，可提前在工厂预制缩短工期，有效改善了钢筋混凝土板柱节点的抗冲切性能。
