The invention provides a tensioning combined steel secondary beam and a tensioning combined beam plate structure, and belongs to the field of fabricated buildings. The tensioning combined steel secondary beam comprises an H-shaped steel beam and at least two high-strength steel cables; the H-shaped steel beam comprises a web, an upper flange and a lower flange, at least two anchoring seats are arranged on the lower flange and located on the two sides of the web respectively, the two anchoring seats on each side are arranged in the length direction of the lower flange, and the high-strength steel cable is tensioned and pre-tightened between the two anchoring seats. The high-strength steel cable is tensioned and then anchored, and the steel cable retracts, so that the lower flange is pressed. The H-shaped steel beams are bent upwards under the action of eccentric axial force, and the axial force of the steel cables and the axial force of the steel beams form self-balance.
本发明提供一种张拉组合钢次梁和张拉组合梁板结构，属于装配式建筑领域，其中张拉组合钢次梁包括H型钢梁和至少二高强度钢索；H型钢梁包括腹板、上翼缘和下翼缘，该下翼缘上位于腹板的两侧分别至少设有两个锚固座，每侧的两个锚固座于下翼缘的长度方向布置，高强度钢索张拉预紧于两个锚固座之间。通过对高强度钢索进行张拉然后进行锚固，钢索回缩导致下翼缘受压。H型钢梁在偏心轴力的作用下，发生往上的弯曲，钢索与钢梁的轴力形成自平衡。
