[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figure 1-11 This application provides the following four preferred embodiments.

[0037] Example 1

[0038] A method for pre-embedded auxiliary installation of ultra-heavy steel structures includes four main steel frame 10s, four support components, and four verification components. Each of the four main steel frame 10s has an adjustment component at its lower end. The method comprises the following steps:

[0039] Step 1: When setting up steel structure main frames 10 with different heights, square assembly plates 14 can be welded at the splicing points of the steel structure main frames 10, and then fixed by bolts. The steel structure main frames 10 and the adjustment components are set up by connecting the square assembly plates 14 and bolts.

[0040] Step 2: Locate the adjustment component and support component using a total station, and fix the lower end of the adjustment component to the reinforcement of the foundation pit bottom slab;

[0041] Step 3: Measure the height of the adjusting component from the ground, and record the adjustment of the adjusting component height using a total station;

[0042] Step 4: Install the support components on one side of the main steel frame 10 to provide load-bearing support for the main steel frame 10;

[0043] Step 5: Insert the verification component at the top of the main steel frame 10 to check and observe whether the heights of the four main steel frame 10s are level;

[0044] Step Six: A horizontal beam 15 is installed horizontally between the upper ends of the four adjacent steel main frames 10 by several bolts. Two diagonal bracing beams 16 are installed between each two adjacent steel main frames 10, and the two diagonal bracing beams 16 are staggered. The staggered positions of the two diagonal bracing beams 16 can be fixed by metal fittings. After the steel main frame 10 is built and passes the acceptance test, the support components are removed and reused.

[0045] Example 2

[0046] Based on Example 1, the height of the bottom steel column 1 is adjusted. With the height of the main steel frame 10 basically controllable, adjusting the height of the bottom steel column 1 improves the efficiency of steel structure construction. The adjustment component includes the bottom steel column 1 and a welded base plate 2. A horizontal plate is horizontally positioned at the lower end of the bottom steel column 1, and an inner cylinder 6 is positioned at the center of the lower end of the horizontal plate. A clamping outer cylinder 5 is positioned at the center of the upper end of the welded base plate 2. The lower end of the inner cylinder 6 is movably inserted into the upper part of the clamping outer cylinder 5. Several clamping pieces are integrally provided at the upper end of the clamping outer cylinder 5, and the outer sides of these clamping pieces are arranged in a conical structure. A push clamping cylinder 4 is threadedly and movably sleeved at the lower end of the outer periphery of the clamping outer cylinder 5, and the upper part of the push clamping cylinder 4 has a conical structure. The design incorporates a conical structure on one side of the push clamp 4 that fits snugly against the conical structure of the clamping plate of the outer cylinder 5. The inner circumference of the clamping plate of the outer cylinder 5 is provided with anti-slip textures. A hydraulic adjusting cylinder 7 is vertically positioned at the upper end of the welded base plate 2 and at the center of the clamping outer cylinder 5. A pick-and-place groove 8 is provided through a horizontal plate at the center of the bottom steel column 1. The width of the pick-and-place groove 8 is greater than the diameter of the hydraulic adjusting cylinder 7. A mating plate 9 is horizontally positioned inside the bottom steel column 1 near the pick-and-place groove 8 via several bolts. The upper end of the hydraulic adjusting cylinder 7 contacts the lower end of the mating plate 9. The pick-and-place groove 8 allows for rapid adjustment of the height of the bottom steel column 1 in the event of uneven height of the bottom raft foundation reinforcement within the foundation pit, in conjunction with the total station elevation.

[0047] When needed, the bottom steel column 1 is lifted by the hydraulic system. After use, the hydraulic adjustment cylinder 7 can be directly taken out from the pick-and-place slot 8 for reuse. After the bottom steel column 1 is lifted to a suitable height, the push clamping cylinder 4 is rotated. At the same time, the conical structure of the push clamping cylinder 4 contacts the conical structure of the clamping plate of the outer cylinder 5. As the push clamping cylinder 4 rises, the clamping plate of the outer cylinder 5 clamps the inner cylinder 6, and the connection between the bottom steel column 1 and the welded base plate 2 is initially stabilized. After the height is determined, the contact position between the clamping outer cylinder 5 and the inner cylinder 6 is fully welded to improve the connection stability between the two.

[0048] Example 3

[0049] Based on Embodiment 2, the main steel frame 10 is laterally supported. A square assembly plate 14 is horizontally provided at the upper end of the bottom steel column 1. The bottom steel column 1 and the main steel frame 10 are fixedly connected by the square assembly plate 14 and several bolts. The support assembly is located on one side of the main steel frame 10. The support assembly includes an assembly sleeve 11 and two support telescopic rods 13. The assembly sleeve 11 is fitted onto the main steel frame 10. Connecting ears 12 are symmetrically provided on both sides of the assembly sleeve 11 away from other main steel frames 10. One side of the support telescopic rod 13 is movably connected to the connecting ear 12 by a pin. The telescopic rod 13 is a structure consisting of two sleeves and a screw. Each sleeve has a threaded disc on one side. The screw passes through the threaded disc on both sides and is inserted into the two sleeves. One sleeve is connected to the connecting lug 12, and a landing block can be welded to one end of the other sleeve. When the telescopic rod 13 is at a 45° angle to the bottom raft reinforcement, the landing point of the telescopic rod 13 can be welded to the bottom raft reinforcement. After the bottom steel column 1 is supported, the telescopic rod 13 can be removed and reused. By adjusting the support length of the telescopic rod 13, the stress on the main steel frame 10 can be distributed.

[0050] Example 4

[0051] Based on Example 3, after the main steel frame 10 is fully erected, a top height verification is performed. Both the main steel frame 10 and the bottom steel columns 1 are square steel pipe structures. Each verification component includes a verification mounting base 17, which is inserted into the upper part of the main steel frame 10. A horizontal overlapping plate 25 is provided at the upper end of the verification mounting base 17. A rotating actuating disc is horizontally mounted at the center of the upper end of the overlapping plate 25. A reflecting prism 18 is tilted on one side of the upper end of the actuating disc. A laser level detection module 20 is horizontally mounted on one side of the upper end of one of the actuating discs. The laser level detection module 20 is positioned to point towards the reflective surface of the reflecting prism 18. A marking arrow 19 is located on the side of the dial closest to the laser level detection module 20, pointing perpendicularly to one side of the overlapping plate 25. A control cavity 21 is provided within the verification mounting base 17. Telescopic grooves are formed through all four sides of the control cavity 21. Spring grooves are formed on the side of each telescopic groove closest to the control cavity 21. A leveling rod 22 is horizontally and movably inserted into each telescopic groove. Each leveling rod 22, positioned within a spring groove, has an ejector block 23. A retraction spring 24 is fitted onto the side of each ejector block 23. A downward screw 26 is vertically positioned at the center of the lower end of the actuating disc. The lower end of the downward screw 26 is threaded into the center of the control cavity 21, and a horizontal push disc 27 is positioned there. The lower end face of the push disc 27 is tapered. The side of each ejector block 23 near the control cavity 21 is also tapered. The tapered sides of the four ejector blocks 23 are respectively fitted to the tapered sides of the push disc 27. The aligning rod 22 passes through the verification mounting base 17 and is respectively connected to the inner side of the steel main frame 10. With the wall abutment setting, when the dial is rotated, the pressing screw 26 and the pushing plate 27 descend synchronously. At this time, the pushing plate 27 pushes the four aligning rods 22 to extend and align the position of the verification mounting base 17. Then, the dial is adjusted by the marked arrow 19. Subsequently, the laser level detection module 20 is connected to one of the verification mounting bases 17. The light emitted by the laser level detection module 20 is refracted by the four reflecting prisms 18 and can be sensed by the sensing module of the laser level detection module 20. Thus, the four steel structure main frames 10 are erected on the same plane.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
