[0021] As Figures 1 to 3 shown, a concave platform with detachable steel structure installation includes a platform with a concave bottom plate 1 installed and a steel column 2 for installing the platform. The concave platform is made of checker plate. The concave bottom plate is installed with a frame 3 made of channel steel. A kick plate 4 is welded at the outer edge of the concave bottom plate. A guardrail is installed along the periphery of the concave bottom plate. The guardrail includes vertical rods 5 and horizontal rods 6. The bottom ends of the vertical rods are perpendicularly installed and welded to the concave bottom plate. The horizontal rods are perpendicularly welded to the top ends of the vertical rods. A waist rod 7 perpendicular to the vertical rods is welded and fixed in the middle of the vertical rods. The vertical rods, horizontal rods, and waist rods are all made of angle steel. The waist rod and the horizontal rod are both arranged along the side of the concave bottom plate and form a concave structure. The horizontal rod, waist rod, and concave bottom plate are respectively provided with a first notch, a second notch, and a third notch from top to bottom. The first notch, the second notch, and the third notch are arranged in a through manner and have the same opening size. The open end of the first notch is detachably connected with a first sealing plate 8 by bolts. The open end of the second notch is detachably connected with a second sealing plate 9 by bolts. The open end of the third notch is detachably connected with a third sealing plate 10 by bolts. The first notch and the first sealing plate enclose a first installation hole. The second notch and the second sealing plate enclose a second installation hole. The third notch and the third sealing plate enclose a third installation hole. Three corbels 11 for supporting the platform are provided on the side of the steel column. The top end of the steel column sequentially passes through the third installation hole, the second installation hole, and the first installation hole, so that the bottom surface of the concave bottom plate and the bottom surface of the third sealing plate respectively abut against the top surface of the corbel. The three corbels are respectively located below the two opposite sides of the third notch and below the third sealing plate. Four jackscrews 12 are installed on both sides opposite to the third notch and on the third sealing plate. The platform and the steel column are tightly fixed by the jackscrews. A butt joint 13 for extension is provided at the top end of the steel column.

[0022] Principle and usage method of a detachable and installable concave platform made of steel structure: Connect and fix the first sealing plate to the open end of the first concave opening with bolts, connect and fix the second sealing plate to the open end of the second concave opening with bolts, and connect and fix the third sealing plate to the open end of the third concave opening with bolts to form three installation holes at the upper, middle, and lower positions. Use a lifting machine to lift the platform above the steel column body, so that the top end of the steel column body sequentially penetrates through the third installation hole, the second installation hole, and the first installation hole until the bottom surface of the platform lands on the top surface of the steel column bracket. At this time, both sides of the third concave opening opposite to the third sealing plate are tightly fixed to the surface of the steel column body through jackscrews. Four jackscrews are installed on each surface to make the platform evenly stressed horizontally. When it is necessary to extend the steel column body at the end of the project with the existing progress, connect and install the next section of the steel column body through the docking interface at the top end of the steel column body, loosen all the jackscrews, remove the first sealing plate, the second sealing plate, and the third sealing plate, lift the platform to a higher section of the steel column body and complete the installation operation, so that the platform can continuously rise with the progress of the project until the end of the project.
