[0002] With the increase in the span of bridges today, more and more bridges are in the form of large-span cable-stayed bridges and suspension bridges. Cable towers are important components of cable-stayed bridges and suspension bridges. They are usually located at both ends of the bridge or in the middle of the bridge span to support and fix cables or cables. Cable towers are generally built with reinforced concrete or steel structures. They have the function of bearing the gravity and cable force of the bridge, and at the same time play the role of supporting and stabilizing the bridge structure. With the widespread use of super-high cable towers, steel structures are increasingly used in bridge towers. Steel towers are generally more than 100 meters high and have various cross-sectional styles. During the construction process, tower cranes are often used for hoisting. Due to the super-high height of the hoisting construction, the tower crane and the steel tower need to be connected to the wall. In the prior art, the wall attachments are generally composed of steel sections, but there is a dangerous operation of high-altitude welding and docking. In addition, after reaching a certain height, there may be a certain risk of deviation between the steel tower and the tower crane, which affects the installation process.

[0003] Therefore, there is an urgent need to provide a tower crane wall attachment device that does not require high-altitude welding and assembly. Utility Model Content

[0032] like Figure 2 As shown, the outer frame 8 of the tower crane is arranged on the periphery of the tower crane body 7, and is used for wall connection with the special-shaped steel tower 6. In this embodiment, the outer frame 8 of the tower crane is a frame assembled by box beams, which is sleeved on the periphery of the tower crane body 7. The first attachment cantilever 4 and the second attachment cantilever 5 are respectively fixed on the outer wall panels on both sides of the special-shaped steel tower 6. It should be noted that the first attachment cantilever 4 and the second attachment cantilever 5 can be erected with various cross-section steels, as long as the calculation is passed. The position of the outer frame 8 of the tower crane corresponds to the position of the first attachment cantilever 4 and the second attachment cantilever 5 outside the special-shaped steel tower 6. The outer frame 8 of the tower crane and the first attachment cantilever 4 and the second attachment cantilever 5 are connected by wall-attached tie rods, and the connection points are provided with tie rod adjustment frames 9 for adjusting the positions of the wall-attached tie rods.

[0033] Figure 3 A bottom view of the wall-attached tie rod provided in this embodiment, Figure 4 1 is an overall schematic diagram of the wall-mounted tie rod. The wall-mounted tie rod is composed of a first male connector 101, a main rod 12, an adjustment section 13, and a second male connector 102 from left to right. In this embodiment, the main rod is a box-shaped steel pipe, but it should be noted that the cross-sectional shape and size of the main rod 12 can be adjusted and can be replaced with other cross-sections that can pass the verification.

[0034] like Figure 5 As shown, the first male joint 101 is provided with a pin hole for fixedly connecting with the tower crane outer frame 8, and the second male joint 102 is provided with a pin hole for fixedly connecting with the first attachment cantilever 4 or the second attachment cantilever 5. The first male joint 101 is connected to the tower crane outer frame 8 by a pin 14, and the second male joint 102 is also connected to the first attachment cantilever 4 or the second attachment cantilever 5 by a pin 14.

[0035] An adjustment section 13 for adjusting the length of the pull rod is provided between the first male connector 101 and the main rod 12. In this embodiment, the adjustment section 13 is adjusted by a nut. The first male connector 101 and the second male connector 102 are both fixed with an in-situ adjustment lug 16 for connecting with the pull rod adjustment frame 9. Figure 4 shown.

[0036] Figure 6A schematic diagram of the rod adjustment frame 9 provided in this embodiment. The rod adjustment frame 9 includes a portal frame upright 91, a portal frame crossbeam 92, an ear plate 93 and a lifting device 94. The portal frame upright 91 is vertically fixed to the outer frame 8 of the tower crane, the first attachment cantilever 4 or the second attachment cantilever 5. A portal frame crossbeam 92 is horizontally arranged on the top of the portal frame upright 91. In this embodiment, the portal frame upright 91 and the portal frame crossbeam 92 are both made of I-beams. It should be noted that in an actual construction site, the portal frame upright 91 and the portal frame crossbeam 92 can also be made of other steel sections such as square steel and round steel.

[0037] A lug plate 93 for setting a lifting device 94 is fixed on the gantry crossbeam 92. In this embodiment, the lifting device 94 is an electric hoist. The hook at one end of the electric hoist is connected to the tower crane outer frame 8, the first attachment bracket 4 or the second attachment bracket 5, and the hook at the other end is connected to the in-position adjustment lug 16 on the wall-attached tie rod, which is used to adjust the posture of the wall-attached tie rod, thereby further completing the work of fixing the through-pin shaft.

[0038] In order to facilitate the hoisting of the wall-mounted tie rod, in this embodiment, a hoisting lug 15 for hoisting the tie rod is welded on the main rod 12 of the wall-mounted tie rod.

[0039] The specific method for construction using the tower crane wall attachment installation structure for a steel tower provided by the utility model is as follows:

[0040] (1) The attachment brackets on the outside of the special-shaped steel tower 6, namely the first attachment bracket 4 and the second attachment bracket 5, are pre-processed in the factory and welded to the outer wall of the special-shaped steel tower 6, and then transported to the construction site as a whole. The special-shaped steel tower 6 is hoisted by a single-sided tower crane. As the installation height of the special-shaped steel tower gradually increases, when it reaches a certain height, it needs to be connected to the wall of the special-shaped steel tower 6 on one side. When the tower crane body 7 is installed, the tower crane outer frame 8 has been installed on the outer periphery of the tower crane body 7 for connecting to the special-shaped steel tower 6 by attaching to the wall.

[0041] (2) Before installing the wall-mounted tie rod, it is necessary to use measuring equipment to verify the elevations of the tower crane outer frame 8, the first attachment bracket 4, and the second attachment bracket 5. After confirmation, use the tower crane to install the first tie rod 1, the second tie rod 2, and the third tie rod 3 in sequence with the help of the lifting ears 15 welded on the wall-mounted tie rod.

[0042] (3) After the wall-mounted tie rod is smoothly positioned at the installation position, the electric hoist and hook device on the temporary adjustment frame 9 of the tie rod can be used to connect the positioning adjustment lugs 16 on the wall-mounted tie rod. When the positioning adjustment lugs 16 on the first male joint 101 and the second male joint 102 of the wall-mounted tie rod are respectively connected to the temporary adjustment frame 9 of the tie rod, the tower crane can be unhooked. Subsequently, the operator uses the electric hoist and fall chain to adjust the positioning form of the wall-mounted tie rod so that the pin holes on both sides of the wall-mounted tie rod are aligned with the attachment brackets (the first attachment bracket 4 and the second attachment bracket 5) on the outside of the special steel tower 6 or the docking second plates on the outer frame 8 of the tower crane, and the pins are inserted to fix them. The three wall-mounted tie rods are installed according to the same steps. When all are completed, the installation of the tower crane wall attachment is completed.

[0043] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
