Example Embodiment
[0061] Example 1:
[0062] See attached figure 1 And figure 2 , The embodiment of the present invention discloses a self-resetting reinforced column foot, which is constructed on the foundation 18, and includes: a steel column 1, a high-strength tie rod 2, a cantilever plate 7, a limit device 3, an anchor rod 9 and a limit position Pad 5;
[0063] The steel column 1 is arranged vertically, and the bottom end is inserted into the limiting groove 11 formed on the top surface of the foundation 18;
[0064] The number of high-strength tie rods 2 is at least one, and it is arranged vertically, the bottom end is connected to the inside of the foundation 18, the rod body passes upwards through the transverse stiffener 17 of the steel column 1, and the top of the transverse stiffener 17 and the high-strength tie rod 2 A disc spring group 16 fixed by high-strength nuts on the bottom surface of the transverse stiffener 17;
[0065] The cantilever plate 7 is horizontally fixed on the outer si...
Example Embodiment
[0080] Example 2:
[0081] The embodiment of the invention discloses a construction and installation method of a self-resetting reinforced column foot, which includes the following steps:
[0082] S1. Put the second disc spring group 4, two limit pads 5 and two high-strength nuts 6 on the anchor rod 9. After prestressing the second disc spring group 4, the limit device 3 is connected to the suspension The pick-up plate 7 is welded and fixed, and then the high-strength nut 6 is loosened, so that the limit pad 5 is stressed on both sides;
[0083] S2. Weld and fix the cantilever plate 7 with the side wall of the steel column 1, and weld the support plate 8 for support;
[0084] S3. The first disc spring group 16 is fitted on the top of the high-strength tie rod 2 and prestressed, and it is fixed by a high-strength nut on the bottom surface of the transverse stiffener 17;
[0085] S4. Pre-bury the foundation 18 for the casing through which the high-strength tie rod 2 and the anchor rod 9 ...
