Fabricated steel-concrete composite beam floor structure
The invention discloses a fabricated steel-concrete composite beam floor structure which comprises a frame column, a profile steel main beam and a profile steel secondary beam, floor plates are laid on the profile steel main beam and the profile steel secondary beam, and a connecting plate is vertically arranged on a web of the profile steel main beam; one end of the floor cover plate is wrapped with angle steel; the floor cover plate is not in contact with the frame columns; the first floor cover plate and the profile steel main beam are connected through the first bolts, so that the combination effect of the profile steel main beam and the first floor is achieved, and the bending resistance and rigidity of the profile steel main beam are improved; the second floor cover plate and the third floor cover plate are connected with the section steel secondary beams through spot welding, and it is guaranteed that the floor cannot collapse under the earthquake effect; the third floor cover plate is in non-rigid connection with the profile steel main beam and can slide relative to the profile steel main beam after being subjected to the earthquake action, and then it is guaranteed that the cover plate is not damaged; in addition, a gap is reserved between the third floor slab and the frame column, it is guaranteed that the frame column deforms under the earthquake effect and does not collide with the floor slab, and the integrity of the floor slab is kept.
本发明公开了一种装配式钢‑混凝土组合梁楼盖结构，包括框架柱、型钢主梁以及型钢次梁，型钢主梁和型钢次梁上铺设有楼盖板，型钢主梁的腹板上垂直设置有连接板；楼盖板的一端包裹有角钢；楼盖板与框架柱不接触；本发明中第一楼盖板与型钢主梁之间通过第一螺栓连接实现型钢主梁与第一楼板的组合作用，提高型钢主梁的抗弯性能及刚度；第二楼盖板和第三楼盖板通过点焊与型钢次梁进行连接，保证楼板在地震作用下不会塌落；第三楼盖板与型钢主梁之间无刚性连接，在受到地震作用后可与型钢主梁发生相对滑动，进而保证盖板不发生损伤；此外，第三楼盖板与框架柱之间留有间隙，保证地震作用下框架柱的变形与楼板不会发生碰撞，保持楼板的整体性。
