Constructional engineering steel structure bearing beam
The invention discloses a constructional engineering steel structure bearing beam. The constructional engineering steel structure bearing beam comprises an upper beam plate, a lower beam plate and an arched plate fixed between the upper beam plate and the lower beam plate, wherein cushion blocks are arranged between the two ends of the arched plate and the upper beam plate, a connecting block is arranged in the middle of the upper end face of the lower beam plate, steel strands anchored through prestress are arranged between the cushion blocks and fixed to the connecting block, the two ends of the steel strand are fixed through clamps fixed to the cushion blocks, and the upper beam plate, the lower beam plate, the arched plate and the cushion blocks penetrate through a fixing shaft. According to the constructional engineering steel structure bearing beam, the steel strands anchored by prestress between the two cushion blocks and the connecting block enable the lower beam plate to reach the required yield strength, the bending resistance of the lower beam plate is high in the normal use process, and the arched plate applies upward force to the upper beam plate, so that the upper beam plate also has certain bending resistance, and the bending resistance of the beam body is better.
本发明公开了一种建筑工程钢结构承重梁，包括上梁板与下梁板以及固定在上梁板与下梁板之间的拱形板，所述拱形板两端的与上梁板之间具有垫块，所述下梁板的上端面的中间位置设有连接块，所述垫块之间有预应力锚固的钢绞线且钢绞线与连接块固定，所述钢绞线的两端使用固定在垫块上的夹具固定，所述上梁板、下梁板、拱形板以及垫块贯穿固定轴。本发明中，两垫块与连接块之间预应力锚固的钢绞线，使得下梁板达到所需要的屈服强度，正常使用过程中下梁板抗弯能力强，拱形板给与上梁板向上的力，使得上梁板也具有一定的抗弯能力，使得梁体抗弯性较好。
