[0020] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the range of protection of the utility model.
[0021] REFERENCE Figures 1-5 An embodiment provided by the utility model: a steel reinforced concrete combination column foot connection, including support plate 1, support plate 1 is provided with multiple, multiple support plate 1 is mutually overlapped between, and the inner wall of support plate 1 is sleeved with steel column 7, transverse steel 5 and longitudinal steel 6, and transverse steel 5 and longitudinal steel 6 are mutually staggered between, and transverse steel 5 and longitudinal steel 6 are jointly fixedly connected on the surface of steel column 7, and steel column 7, transverse steel 5 and longitudinal steel 6 are combined into a whole, and the middle part of the whole is fixedly connected with shear frame 9, and the inner wall of support plate 1 is provided with through -hole 2.
[0022] The device combines the steel column 7, the transverse steel bars 5 and the longitudinal steel bars 6 into a whole, facilitates the pouring of the concrete inner wall, and improves the compression resistance through the longitudinal and transverse intersection of the steel bars.
[0023] Preferably, the transverse steel bars 5 are provided with multiple steel bars, and the surfaces of four transverse steel bars 5 are fixedly connected with threaded rods 3.
[0024] Preferably, the surface of the steel column 7 is sleeved with a shear key 8.
