DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show components relevant to the present invention. While the present invention is described in detail using structural diagrams, these diagrams are merely examples and are not intended to limit the scope of protection of the present invention.

[0029] See also Figures 1-7 An anti-tilt steel column includes an octagonal base plate 1 with vertical holes 1a and inclined holes 1b extending through the upper and lower surfaces for insertion of connecting bolts. The connecting bolts inserted into the vertical holes 1a are embedded components in the foundation. A column shaft 2 is vertically connected to the octagonal base plate 1, and a reinforcing rib 6 is provided between the bottom end of the column shaft 2 and the octagonal base plate 1.

[0030] Specifically, the column body 2 includes a central tube 2a, and right-angle plates 2b are evenly and equidistantly arranged around the central tube 2a. The right-angle plates 2b are connected to the central tube 2a through webs 2c, and the webs 2c are vertically arranged between adjacent ones.

[0031] The upper surface of the foundation needs to be provided with a concave cavity, and an insertion mechanism 4 for inserting into the cavity is vertically connected to the lower side of the octagonal bottom plate 1. The insertion mechanism 4 includes a support block 4a and support claws 4b arranged around it. The side close to the support block 4a and the support claw 4b is an inclined surface, and the bottom of the support block 4a is a conical surface with the tip downward, which is convenient for inserting it into the cavity. The top of the support block 4a is connected to a pull rod 4c, and the upper part of the pull rod 4c is provided with a thread and is screwed with a pull rod screw 4d. The pull rod 4c passes through the middle The core tube 2a is exposed at its top, the pull rod screw 4d is located on the center tube 2a, the support claw 4b is bendable, and its top is connected to the bottom surface of the octagonal base plate 1. The support block 4a and the pull rod 4c can move up and down synchronously. By turning the pull rod screw 4d on the center tube 2a, the pull rod 4c moves up with the support block 4a under the action of the threaded connection. The oblique side surface of the support block 4a abuts against the support claw 4b and bends outward. The entire insertion mechanism 4 is tightly connected to the cavity, making it difficult to pull out and the column body 2 difficult to tip over.

[0032] To further prevent tipping, the right-angle plate 2b is connected to the outside with a diagonal cable 3, and the highest point of the diagonal cable 3 is connected to a horizontally arranged hook 5. The two ends of the hook 5 are hooked into the hook holes opened on the side of the right-angle plate 2b. The hook holes are arranged in several rows from top to bottom, which are concentrated in the upper half of the right-angle plate 2b. A hook 5 is arranged between every two adjacent right-angle plates 2b, and the two ends of each hook 5 are respectively hooked into a hook hole. The connection height between the hook 5 and the right-angle plate 2b can be adjusted as needed, and the bottom end of the diagonal cable 3 is fixed to the ground.

[0033] The installation of steel columns is a crucial step in construction, especially for high-rise buildings, bridges, and other large structures. Correct installation procedures ensure the safety and stability of the structure. Before installation, ensure the foundation is sufficiently solid, and perform secondary reinforcement if necessary. It's also important to confirm that the embedded parts are correctly positioned in the foundation; these parts will be used to secure the baseplate of the steel column. After the embedded bolts in the foundation are inserted into the vertical holes 1a, tighten and lock them downward with screws. Insert the bolts obliquely from top to bottom into the oblique holes 1b. Then, tighten the pull rod screw 4d on top of the center tube 2a. The threaded connection causes the pull rod 4c to move upward with the support block 4a. The oblique side of the support block 4a abuts against the support claw 4b, bending and deforming outward. The entire insertion mechanism 4 is tightly connected to the cavity in the foundation. After installation, pour shrinkage-free fine stone concrete into the gap. Finally, select the height of the connection point between the hook 5 and the angle plate 2b as needed, and the bottom end of the inclined cable 3 is connected and fixed to the ground. During the installation process, the verticality of the column 2 must be checked using a theodolite or other measuring tools.

[0034] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. It should be pointed out that for those skilled in the art, without departing from the concept of the present invention, changes, modifications or additions should all fall within the protection scope of the present invention.
