[0006] 3. When assembling columns at high altitudes, it is difficult to ensure the accuracy and stability of the assembly due to the complex working environment;

[0007] 4. Working at heights itself carries significant safety risks, and the difficulty in controlling construction accuracy further increases the safety risks during the construction process. Utility Model Content

[0026] See also Figure 1-7 , further illustrate the embodiments of the present utility model;

[0027] like Figure 1-2 As shown, a rapid assembly platform for bridge construction is used to assemble column units 3, which include columns 31 and connecting rods 32. There are four columns 31 arranged in a square shape, and a plurality of connecting rods 32 are provided and respectively fixed between two adjacent columns 31.

[0028] The platform includes: embedded parts 1, adjusting parts 2 and ladder cage 4. The embedded parts 1 are provided with several and are surrounded by a square. Its shape follows the column unit 3 to facilitate the installation of the column unit 3 in the later stage. The embedded parts 1 are fixed to the ground. The adjusting parts 2 are provided with several and are detachably connected to the embedded parts 1. A concrete foundation 5 is poured on the embedded parts 1. The thickness of the concrete foundation 5 is 200mm. In order to strengthen the strength of the concrete foundation 5, two layers of steel mesh are set in the concrete foundation 5. The embedded parts 1 and the concrete foundation 5 are connected to the embedded parts 1. The setting is to fix the adjusting part 2, the interior of the adjusting part 2 is hollow, and is used to install the fixed column 31; the ladder cage 4 is provided with two rows and is located on both sides of the square embedded part 1, and the two rows of ladder cages 4 are fixed on the concrete foundation 5. The number of ladder cages 4 is determined according to the height of the column 31. The setting of the ladder cage 4 is to facilitate the installation of the top of the column unit 3. It should be noted that the connecting rod 32 at every 4m on the column 31 is connected to the two corners of the ladder cage 4, which is conducive to the ladder cage 4 and the column 31 standing stably on the ground.

[0029] like Figure 3-4 As shown, the embedded part 1 specifically includes a support rod 11 and a steel plate 12. The support rod 11 is provided with a number of uniformly perforated plugs welded on the steel plate 12, and the lower ends of the support rods 11 are embedded in the ground. The support rods 11 are threaded steel bars, and the depth of the threaded steel bars embedded in the ground is not less than 200 mm.

[0030] like Figure 5-6As shown, the adjusting member 2 specifically includes a base 21 and a stiffening plate 22. The base 21 is bolted to the steel plate 12. The stiffening plates 22 are provided and are evenly welded to the lower edge of the top of the base 21. The stiffening plates 22 are steel plates and are provided to enhance the strength of the base 21. Specifically, the base 21 includes a steel plate 211 and a steel pipe 212. The steel pipe 212 is perforated and plug-welded to the steel plate 211, and a circle of bolt holes is opened on the surface of the steel plate 211. Several stiffening plates 22 are welded between the bottom of the steel plate 211 and the steel pipe 212. The base 21 is made of an imitation flange because flanges are provided at the upper and lower ends of each column 31.

[0031] The steps for making the platform and assembling the super high tower are as follows:

[0032] The first step is to level the site to ensure the flatness and bearing capacity of the ground;

[0033] The second step is to uniformly perforate and plug-weld a number of support rods 11 to the steel plate 12, and the lower ends of the support rods 11 are embedded in the ground to a depth of not less than 200 mm. Then, two layers of steel mesh are laid on the embedded parts 1, and concrete is poured to form a concrete foundation 5.

[0034] The third step is to place the adjusting piece 2 in the center of the embedded piece 1 after the concrete is cured. The embedded piece and the adjusting piece 2 are connected with bolts. The levelness of the adjusting piece 2 is adjusted to ensure that the four adjusting pieces 2 are on the same horizontal plane.

[0035] The fourth step is to place the ladder cage 4 at the designated location. The two ladder cages 4 on the same side are connected by connecting rods. A connecting rod 32 is set every 4 meters on the column 31 to connect the two corners of the ladder cage 4.

[0036] The fifth step is to use a crane to hoist a single column 31 onto the adjusting member 2. After the flange holes on the column 31 correspond to the bolt holes on the adjusting member 2, use M30 refined bolts to fix them. After the four columns 31 are fixed on the adjusting member 2, the staff climbs to the top of the column 31 through the ladder inside the ladder cage 4 and installs the top parallel connection until one column unit 3 is assembled;

[0037] Step 6: Loosen the fixing bolts at the bottom of the column 31 and use a tower crane to lift the assembled column unit 3 to the designated position of the super-high tower using a four-point lifting method;

[0038] Step 7: Repeat the above steps until several column units 3 are erected to form an ultra-high tower.

[0039] Through the setting of this platform, every four columns 31 can be spliced to form a column unit 3, and then several column units 3 can be assembled one by one to form an ultra-high tower. In this way, compared with the hoisting and assembly of a single column 31, the assembly accuracy and stability of the column unit 3 and the column unit 3 of this solution are higher, and the construction progress is faster, which effectively solves the current problem that the hoisting and assembly process of a single column 31 is cumbersome, requiring a lot of time and labor, resulting in slow overall construction progress; a single column 31 is difficult to control during the high-altitude hoisting process due to its large weight and size; when assembling the columns 31 at high altitude, due to the complex working environment, it is difficult to ensure the accuracy and stability of the assembly, and the high-altitude operation itself has a large safety risk. In addition, the construction accuracy is difficult to control, which further increases the safety risk problem during the construction process.
