Embedded cladding hoop-shaped steel-concrete composite beam
The invention discloses an embedded cladding hoop-shaped steel-concrete composite beam which comprises an upper steel plate and a lower steel plate. The upper steel plate and the lower steel plate aresymmetrically arranged, arc-shaped convex surfaces are arranged on the opposite sides of the upper steel plate and the lower steel plate in the width direction of the upper steel plate and the lowersteel plate, and shear-resistant rib units are evenly welded between the upper steel plate and the lower steel plate in the length direction of the upper steel plate and the lower steel plate. Each shear-resistant rib unit comprises two shear-resistant rib single bodies which are symmetrically arranged, and each shear-resistant rib single body comprises a lower arc-shaped steel bar tightly attached to the lower arc surface in an obliquely straddling manner and an upper arc-shaped steel bar tightly attached to the upper arc surface in an obliquely straddling manner. Through the arrangement of cross-shaped steel bar frames, on one hand, each cross-shaped steel bar frame abuts against the corresponding upper arc-shaped steel bar, the corresponding lower arc-shaped steel bar and two arc-shapeddiagonal draw steel bars to prevent the upper arc-shaped steel bar, the lower arc-shaped steel bar and the two arc-shaped diagonal draw steel bars from deforming, and on the other hand, the cohesiveness of concrete is improved, so that the strength of a beam body is improved. Through the arrangement of hoop-shaped tensile ribs, the multiple shear-resistant rib single bodies generate relative displacement, so that the multiple shear-resistant rib single bodies form a whole, and the bearing capacity of the beam body is greatly improved.
本发明公开了一种嵌入式外包箍状钢‑混凝土组合梁，包括上钢板与下钢板，所述上钢板与下钢板对称设置，且上钢板与下钢板相对一侧沿其宽度方向设置有弧状凸面，上钢板与下钢板之间沿其长度方向均匀焊接有抗剪筋单元，抗剪筋单元包括两个对称设置的抗剪筋单体，抗剪筋单体包括紧贴下弧面斜跨设置的下弧形钢筋以及紧贴上弧面斜跨设置的上弧形钢筋。本发明十字型钢筋架的设置一方面十字型钢筋架抵触上弧形钢筋与下弧形钢筋以及两根弧状斜拉钢筋防止上弧形钢筋与下弧形钢筋以及两根弧状斜拉钢筋发生形变，另一方提高了混凝土之间的粘结性，进而提高梁体强度，而箍状抗拉筋的设置使得多个抗剪筋单体发生相对位移使得多个抗剪筋单体形成一体，大大提高梁体承重力。
