Prestressed concrete secondary beam and frame structure
The invention provides a prestressed concrete secondary beam and a frame structure. The prestressed concrete secondary beam comprises a main body part. The main body part comprises an upper flange, a lower flange and a web plate arranged between the upper flange and the lower flange; the upper flange and the lower flange are equal in width and flush in side face, and the width of the web is smaller than that of the upper flange and the lower flange. And at least one prestressed tendon is arranged in the lower flange in the length direction in a penetrating manner. The width of the upper flange and the width of the lower flange are equal, and the side faces of the upper flange and the lower flange are flush, so that the overall shape of the main body part is regular, the rigidity of the overall structure can be maintained, the problem that the rigidity is not matched or unbalanced due to the irregular shape is solved, and the appearance is more regular. Moreover, the prestressed tendons are arranged in the lower flanges, so that the crack resistance and the bearing capacity of the prestressed concrete secondary beam can be enhanced.
本申请提供了一种预应力砼次梁和框架结构。该预应力砼次梁包括：主体部。主体部包括上翼缘、下翼缘以及设于之间的腹板。上翼缘和下翼缘宽度相等且侧面齐平，腹板的宽度小于上翼缘和下翼缘的宽度。下翼缘内沿长度方向穿设有至少一个预应力筋。本申请中上翼缘和下翼缘宽度相等且侧面齐平，使得主体部整体的形状较为规整，有助于维持整体结构的刚度，减少因不规则形状导致的刚度不匹配或不均衡问题，外观也更加整齐。而且，下翼缘内设置预应力筋，能够增强预应力砼次梁的抗裂性和承载能力。
