Anti-cracking spliced steel structure bracket

LYU SHANG'AN

The invention discloses an anti-cracking spliced steel structure bracket. The anti-cracking spliced steel structure bracket comprises a large cross beam and a longitudinal steel beam, the longitudinalsteel beam is fixedly connected with the large cross beam, the connection between the longitudinal steel beam and the large cross beam is in a trapezoidal shape, two waists of the trapezoid are arc edges, conical groove holes are formed in the arc edges of the longitudinal steel beam, triangular grooves are further formed in the upper and lower sides of the groove holes, a small cross beam is vertically installed above the longitudinal steel beam, the small cross beam is fixedly connected with the longitudinal steel beam through a straight plate, and inserting grooves which are of an integrated structure with the small steel beam are further formed in the two sides of the straight plate. A cross bar in the middle and used for bearing force firstly is optimized, a certain amount of activity space is provided for the cross bar, and meanwhile it is guaranteed that the cross bar cannot fall off.

本发明公开了一种防裂的拼接式钢结构支架，包括大横梁及纵钢梁，所述纵钢梁与大横梁固定连接，所述纵钢梁与大横梁连接处为梯形状且该梯形两腰为弧边，所述纵钢梁的弧边上开有圆锥形的槽孔，所述槽孔的上下两侧还开有三角状的槽沟，所述纵钢梁上方垂直安装有小横梁，所述小横梁与纵钢梁通过直板固定连接，所述直板两侧还设有与小横梁为一体化结构的插槽，对于在中部的用于先承受力的横杆做了优化处理，给予了横杆一定量的活动空间，同时保证了横杆不会脱落。
