[0037] The tower-mounted assembled construction platform provided in this embodiment uses a bracket 200 to set up a rectangular frame 100 that is larger than the tower on the column 400 of the tower, which is convenient for personnel to inspect and maintain. A handrail 300 is provided on the rectangular frame 100 so that maintenance personnel can stand on the rectangular frame 100 to work. Moreover, at least part of the structure of the bracket 200, the column 400 and the handrail 300 are detachably connected, and welding and other methods are not used, which reduces the time of high-altitude welding operations, improves construction safety, has high construction efficiency, and is convenient for later dismantling.

[0038] Specifically, the rectangular frame 100 includes a plurality of frame beams 11, which are sequentially connected to form a closed rectangular frame 100, and a wire mesh 12 is filled in each frame beam 11. The frame beams 11 are composed of a plurality of channel steels welded to form a ladder shape. The frame beams 11 are provided with a plurality of first reserved holes 111 and second reserved holes 112, which are used to connect to the handrail 300 and the bracket 200, respectively.

The bolt 500 includes a first bolt 500 and a third bolt 500. The first crossbar 21 is connected to the two vertical frame beams 11 respectively through the third bolt 500. The first inner ear plate 23 is welded to the inner side of the flange plate of the frame beam 11, and the first outer ear plate 24 is welded to the corner post 41. The first inner ear plate 23 and the first outer ear plate 24 are connected by the first bolt 500. In this way, the corner post 41 and the two vertically connected frame beams 11 are connected through the first bracket 200. Figures 7-8 shown.

[0043] In order to connect the center column 42 and the two frame beams 11 connected in a straight line, the second bracket 200 includes a second cross bar 25, a second outer ear plate 27 and a bolt 500. The bolt 500 includes a second bolt 500 and a fourth bolt 500. The second cross bar 25 is connected to the frame beam 11 through the fourth bolt 500. The second outer ear plate 27 is welded to the center column 42. The second cross bar 25 and the second outer ear plate 27 are connected by the second bolt 500. In this way, the center column 42 and the two frame beams 11 connected in a straight line are connected through the second bracket 200. Figures 9-10 shown.

[0044] Furthermore, the crossbars are made of channel steel and are internally provided with stiffening ribs. The first crossbar 21 is made of channel steel with two third pre-set holes 211 in the upper layer for connection to the frame beam 11 via third bolts 500. The first crossbar 21 has a first stiffening rib 22 installed inside. The second crossbar 25 is made of double-jointed channel steel back-to-back. The upper layer of the channel steel has a fourth pre-set hole 251 for connection to the frame beam 11 via fourth bolts 500. The second crossbar 25 has a second stiffening rib 26 installed inside.

The guardrail frame 31 is welded by steel pipes, and the cross section of the steel pipe is smaller than the cross section of the first reserved hole 111 on the frame beam 11. The handrail 300 is fixed to the rectangular frame 100 by inserting the vertical steel pipe of the handrail 300 into the first reserved hole 111. Figure 11 shown.

[0046] The usage of the embodiment of the utility model is as follows:

[0047] When prefabricating the standard segment of the tower, the first outer ear plate 24 and the second outer ear plate 27 are welded to the corner column 41 and the middle column 42 respectively. After the standard segment is installed, the first bracket 200 and the second bracket 200 are welded on the ground. After the other components are completed, the first bracket 200 and the second bracket 200 are hoisted to the first outer ear plate 24 of the corner column 41 and the second outer ear plate 27 of the middle column 42 respectively. The first bracket 200 and the second bracket 200 are fixed to the corner column 41 and the column 400 respectively by the first bolt 500 and the second bolt 500. The rectangular frame 100 and the support are assembled on the ground. Handrail 300, first place the rectangular frame 100 at the corresponding positions of the first bracket 200 and the second bracket 200, so that the second reserved hole 112 of the frame beam 11 is aligned with the third reserved hole 211 of the first bracket 200 and the fourth reserved hole 251 of the second bracket 200, respectively, and then use the third bolt 500 and the fourth bolt 500 to fix the frame beam 11 to the first bracket 200 and the second bracket 200 respectively, and then insert the lower round steel pipe of the handrail 300 into the first reserved hole 111 of the frame beam 11 to fix the handrail 300 and complete the installation and installation of the maintenance platform.
