Embodiment Construction
[0015] Embodiments of the present invention: as image 3 , Figure 4 As shown, when adopting the present invention to strengthen the base plate of the column foot, it can be carried out as follows:
[0016] First, thoroughly remove the paint and rust on the steel surface within the range of the foot of the steel column 1, so as to strengthen the bond between the concrete and the foot of the column;
[0017] Second, within the range of the column foot of the steel column 1, weld anchor reinforcement bars 6 on the column in a plum blossom distribution manner. The distance between the anchor bars is 150mm and the diameter is 16-20mm. In order to increase the bonding force, the anchor bars should be Use grade II steel bars with patterns, the length of the anchor bar is 20d, and d is the diameter of the anchor bar. If the length is greater than the width of the column foot and cannot fit, the longer part can be bent to make an anchor with a hook at one end. muscle

The invention discloses a steel column base reinforcement structure which includes a steel column (1), a side stiffening rib plate (2), a middle stiffening rib plate (3), a column base bottom plate (4) and a column base bolt (7). The invention is characterized in that anchor reinforcing steel bars (6) are welded with the steel column (1) and the side stiffening rib plate (2); a rigid crossbeam (8) is welded with the edge of the column limb wing of the steel column (1); concrete (5) is cast in the intercolumnar range of the steel column (1). The concrete (5) is 100mm higher than the top part of the rigid crossbeam (8). The space between the anchor reinforcing steel bars (6) is 150mm; the diameters of the anchor reinforcing steel bars (6) are 16mm to 20mm. The grade of the concrete (5) is higher than C20. The height of the rigid crossbeam (8) is arranged above the top part of the side stiffening rib plate (2). The invention can effectively realize the reinforcement for the column base bottom plate and reduces the deformation of the bottom plate caused by the welding stress of the traditional reinforcing mode; besides, the steel column base reinforcement structure is simple and easy to be implemented and has strong operability.
Description
technical field [0001] The invention relates to a steel column foot reinforcing structure of a steel structure building, and the invention can simply and effectively realize the reinforcement of the column foot bottom plate. Background technique [0002] Due to its fast construction and light weight, steel structure buildings have been widely used in building structures in recent years, especially in factory building structures. As the final force transmission component of the steel structure system, the steel column foot The safety of the steel column is even more important. Sometimes due to human deviations in the design and construction, or the additional load of the building after the construction is completed, when these problems are found, the steel column foot has often been constructed. The thickness of the base plate is insufficient, and its stiffness is not enough to resist the bending moment on the base plate. At this time, the base plate will be twisted and defor...
