[0005] The anchor-type embedded parts include multiple column feet, column receiving end plates and four column positioning plates; the column receiving end plates are fixed to the surface of the foundation cushion layer through multiple column feet, and multiple column feet are connected to the foundation cushion layer through adjustable connecting parts; the four column positioning plates are arranged on the surface of the column receiving end plate at the positions of the four side plates of the inner diameter of the shell column.

[0006] Furthermore, the foundation cushion layer is fixed to the ground by a plurality of foundation piles; and the connection between the foundation cushion layer and the foundation piles is thickened by pouring concrete.

[0007] Furthermore, the end of the foundation pile passes through the foundation cushion layer, and the end of the foundation pile is provided with a pile head reserved reinforcement; when the anchor type embedded part is fixed to the surface of the foundation cushion layer, the top angle of the column receiving end plate is positioned and connected with the nearby pile head reserved reinforcement through the oblique fixed reinforcement.

[0008] Furthermore, the column foot includes an anchor end plate and anchor bars; the anchor end plate is fixed to the surface of the foundation cushion layer through the adjustable connecting piece, and a plurality of anchor bars are arranged between the anchor end plate and the column receiving end plate.

[0009] Further, the adjustable connector includes a chemical anchor bolt, an upper nut and a lower nut;

[0026] The reserved reinforcement at the end of the pile head and the anchor-type embedded parts are used to fix the position, which facilitates the stability of the subsequent concrete pouring and avoids the position displacement of the anchor-type embedded parts due to the pouring of the foundation concrete, thereby improving the construction accuracy and ensuring the construction quality.

[0027] The adjustable connector formed by chemical anchor bolts, upper nuts and lower nuts is used to fix the foundation cushion and the anchor-type embedded parts, so that the anchor-type embedded parts can be fine-tuned in horizontal and vertical positions during installation, avoiding displacement of the shell column installation and further ensuring the construction quality.

[0028] At the same time, the design of chemical anchor bolts, upper nuts and lower nuts facilitates the preliminary adjustment of the elevation of anchor-type embedded parts. After pouring the foundation concrete and assembling the shell column, the elevation of the shell column can be adjusted secondary by adjusting the positioning plate, thereby further ensuring the accuracy of the construction and greatly reducing the complexity of the construction.

[0029] The foundation cushion, anchor embedded parts and shell columns are all prefabricated in the factory and then installed and poured on site, which reduces the difficulty of construction, speeds up the construction speed and greatly improves the installation efficiency.

[0030] The installation method of the present invention installs the foundation cushion layer, the anchor-bar embedded parts and the shell column in order from bottom to top. The installation method is simple, employees do not need professional training, and labor costs are reduced. BRIEF DESCRIPTION OF THE DRAWINGS
