Same-span frame beam structure with variable section height
The invention discloses a same-span frame beam structure with variable section height, comprising: a high-span section, one end of which is connected to a frame column; the variable-diameter section is provided with a large-head end and a small-head end which are opposite, the height of the section of the variable-diameter section is gradually reduced from the large-head end to the small-head end, and the large-head end is connected to the other end of the high-span section; an anchoring rib is formed at one end of the low-span section and the longitudinal main rib connected to the small head end and the lower portion of the high-span section, the anchoring rib comprises an inclined section arranged in the slope forming direction of the bottom beam face of the reducing section and a straight section connected to the inclined section, the inclined section obliquely and upwards extends to the upper portion of the low-span section, and the straight section and the longitudinal main rib on the upper portion of the low-span section are arranged in the same direction; longitudinal main ribs on the lower portion of the low-span section penetrate through the high-span section and extend into the frame column in the full length direction, and stirrups at the other end of the high-span section, stirrups at the small-head end and stirrups at the end, close to the variable-diameter section, of the low-span section are arranged in a densified mode. The problem that the variable cross section of the same-span beam becomes a weak stress point due to the height change of the cross section of the same-span beam is solved.
本发明公开了一种截面高度变化的同跨框架梁结构，包括：高跨段，其一端连接于框架柱；变径段，具有相对的一大头端和一小头端，其截面高度自大头端向小头端逐渐缩小，大头端连接于高跨段的另一端；低跨段，连接于小头端，高跨段的下部的纵向主筋的一端形成有锚固筋，锚固筋包括沿变径段的底部梁面的成坡方向设置的倾斜段和连接于倾斜段的平直段，倾斜段斜向上伸至低跨段的上部，平直段与低跨段的上部的纵向主筋同向设置，低跨段的下部的纵向主筋贯穿高跨段通长伸至框架柱内，高跨段的另一端的箍筋、小头端的箍筋以及低跨段的靠近变径段的一端的箍筋加密设置。本发明解决了由于同跨梁截面高度变化导致同跨梁变截面处成为受力薄弱点的问题。
