The lower assembly component (5) is tilted up so that the two lower U-shaped steels (401) and the I-shaped steel (402) can be separated from the two slots (502) and the card slot (504) at the bottom of the mounting seat (501); Secondly, the two U-shaped steels (401) and the I-shaped steel (402) at the bottom are lifted up, so that the U-shaped steel (401) at the bottom is separated from the side stop assembly (2), so that the U-shaped steel (401) is separated from the two baffles (201) and the two ear plates (202), and the I-shaped steel (402) can be separated from the two first support frames (3), so that the base (1) and the plurality of base columns (4) can be separated, and the base (1) and the plurality of base columns (4) can be independently transferred; When assembling the steel structure foundation, the bottoms of the two U-shaped steels (401) are inserted into the side baffle assembly (2), so that the U-shaped steels (401) are in contact with the baffle plate (201) and the ear plate (202), and the U-shaped steels (401) are supported by the baffle plate (201) and the ear plate (202), thereby improving the stability of the U-shaped steels (401). Next, the I-shaped steel (402) is inserted between the two first support frames (3), so that the two sides of the I-shaped steel (402) overlap with the opposite surfaces of the two U-shaped steels (401), so that the I-shaped steel (402) can support and limit the two U-shaped steels (401), and then the mounting seat (501) is installed. ) two slots (502) and the card slot (504) at the bottom are aligned with the two U-shaped steels (401) and the I-shaped steel (402) below, so that the top of the base column (4) can be reinforced, and then the two U-shaped steels (401) are inserted into the slots (502) from the top of the mounting seat (501), and then the I-shaped steel (402) is inserted into the two second support frames (503), so that the two second support frames (503) can support and limit the I-shaped steel (402), and the I-shaped steel (402) is in contact with the inner walls of the two U-shaped steels (401) above. Similarly, the upper assembly component (5) is installed on the top of the base column (4); After the assembly of the base (1) and the base column (4) is completed, the slide plate (703) is pulled to slide in the slideway (702) in the fixing seat (701), and one side of the slide plate (703) is embedded in the clamping hole (8) on the base (1), and it is fixedly installed on one side of the base (1) with a plurality of mounting screws (705). Similarly, the slide plate (703) on the other side is operated to connect the two bases (1) through the slide plate (703) and the fixing seat (701). The connection work of the bases (1) with different spacings can be met by adjusting the distance between the two slide plates (703). The position of the slide plate (703) can be locked by tightening the fastening bolts (704) on the fixing seat (701).
