Built-in steel support connecting structure of building deep foundation pit steel-concrete support
The invention relates to the technical field of deep foundation pit reinforced concrete supports, in particular to a building deep foundation pit reinforced concrete support built-in steel support connecting structure which comprises I-shaped steel, end flanges are welded to the two ends of the I-shaped steel, a plurality of first rib plates are welded between the two sides of the I-shaped steel and the end flanges, and slurry flowing holes are formed in the first rib plates. Tensile pieces are further arranged on the two sides of the I-shaped steel, the I-shaped steel is composed of two flange plates and a web plate, the web plate is welded between the two flange plates, each tensile piece comprises a longitudinal main rib, a vertical inserting rib and a transverse pulling rib, and the tensile pieces are pre-welded to the two sides of the web plate. The transverse tie bars are used for hooking the longitudinal main bars and the vertical joint bars on the two sides, and a plurality of second rib plates are welded between the end flange and the two flange plates. According to the invention, the first rib plate and the second rib plate are welded between the end flange and the I-shaped steel, so that the connection between the end flange and the I-shaped steel is more stable, and the compressive strength is high.
本发明涉及深基坑钢混支撑技术领域，具体涉及一种建筑深基坑钢混支撑内置钢支撑连接结构，包括工字钢，所述工字钢两端均焊接有端部法兰，所述工字钢两侧与端部法兰之间均焊接有多个第一筋板，且第一筋板上均开有流浆孔，所述工字钢两侧还设有抗拉件，所述工字钢由两个翼缘板以及一个腹板组成，所述腹板焊接于两个翼缘板之间，所述抗拉件包括纵向主筋、竖向插筋与横向拉筋，所述抗拉件预焊接于腹板两侧，所述横向拉筋用于勾紧两侧的纵向主筋、竖向插筋，所述端部法兰与两个翼缘板之间焊接有多个第二筋板。本发明，在端部法兰与工字钢之间焊接第一筋板、第二筋板，使得端部法兰与工字钢之间连接更加稳固，抗压强度大。
