DETAILED DESCRIPTION

[0024] Figures 1 to 5 This is the best embodiment of the rear-mounted fixed support for the tower crane. Figures 1 to 5 The utility model is further described.

[0025] Reference Figure 1-3 The rear-mounted standardized tower crane attachment and fixing support includes a front panel 1, a steel back rib 2 and a tension bolt 3. The front side of the front panel 1 is provided with two horizontally arranged attachment ear plates 4. The front panel 1 is arranged on the front side of the building column 16, and the steel back rib 2 is arranged on the rear side of the building column 16. Multiple groups of steel back ribs 2 are arranged horizontally from top to bottom. The front end of the tension bolt 3 is fixedly connected to the front panel 1 through a nut, and the rear end of the tension bolt 3 is arranged between the two steel back ribs 2. The rear end of the tension bolt 3 is fixedly connected to the steel back rib 2 through a nut, thereby realizing a fixed connection between the attachment and fixing support and the building column 16.

[0026] The dimensions of the front panel 1 are determined by the cross-sectional dimensions of the building columns 16. It is constructed from 20mm thick steel plate, with each side extending 80-100mm beyond the column edge. Bolt holes are symmetrically positioned on both sides of the front panel 1 for the insertion of tension bolts 3. These bolts are M24 high-strength bolts, threading through the bolt holes in the front panel 1 and the steel back ribs 2, securing the two together. Each set of steel back ribs 2 is constructed from two 10# channel steels, back-to-back, with the openings of the steel back ribs 2 facing away from the tension bolts 3. The two channels are separated by rebar (not shown), which is welded to the slats. The spacing between the channels is the diameter of the tension bolts 3 plus 4mm, to facilitate the insertion of the bolts 3.

[0027] The attachment lugs 4 are the same as those used for tower crane attachment brackets and are welded directly to the center of the front panel 1. The distance between the two lugs 4 is consistent with the spacing between the lugs 4 of the original bracket. To ensure the strength of the attachment lugs 4, three lug stiffening ribs 8 are provided on each side of the lugs 4.

[0028] In order to reduce the impact of the attached fixed support on the structure during use, a front anti-wear and shock-proof rubber pad 12 is provided on the rear side of the front panel 1 and the inner side of the column side wing plate 9, and a rear anti-wear and shock-proof rubber pad 13 is added between each steel back rib 2 and the building column 16.

[0029] Column-supporting side wing panels 9 are provided at both ends of the rear side of the front panel 1. Side wing panel pressing mechanisms are also provided at both ends of the front panel 1 to press the outer sides of the column-supporting side wing panels 9. The column-supporting side wing panels 9 can effectively control the position of the front panel 1 to prevent it from shifting during use. The side wing panel pressing mechanisms can also adapt the column-supporting side wing panels 9 to building columns 16 of different sizes, making them more flexible and convenient to use.

[0030] In this embodiment, the column side wing plate 9 is movably connected to the front panel 1. Specifically, horizontal long holes 15 are provided on both sides of the front panel 1. One side of the column side wing plate 9 is provided with a connecting column slidably arranged in the long hole 15. The column side wing plate 9 is connected to the front panel 1 through the connecting column, which is convenient for installation.

[0031] Specifically, the side wing plate clamping mechanism includes a clamping fixing seat 10 and a clamping bolt 11. The clamping fixing seat 10 is arranged on the outside of the column side wing plate 9. The clamping bolt 11 is threadedly connected to the clamping fixing seat 10. One end of the clamping bolt 11 contacts the outside of the column side wing plate 9. The column side wing plate 9 is pressed against the side of the building column 16 by the clamping bolt 11, thereby fixing the position of the front panel 1.

[0032] To ensure the stability and structural strength of the front panel 1, stiffening ribs are carefully designed on the front side of the front panel 1. Specifically, the front side of the front panel 1 is provided with a first front panel stiffening rib 5, a second front panel stiffening rib 6, and a third front panel stiffening rib 7. The two first front panel stiffening ribs 5 are horizontally arranged on both sides of the ear plate 4, the two second front panel stiffening ribs 6 are vertically arranged on both sides of the ear plate 4, the third front panel stiffening rib 7 is arranged between the second front panel stiffening ribs 6 and the front panel 1, and the third front panel stiffening rib 7 is arranged on the side of the second front panel stiffening rib 6 away from the attachment ear plate 4, and the tension bolt 3 is arranged between the two third front panel stiffening ribs 7.

[0033] The first front panel stiffening ribs 5, the second front panel stiffening ribs 6 and the third front panel stiffening ribs 7 are made of 20 mm thick steel plates and are distributed at multiple key positions of the front panel 1. The second front panel stiffening ribs 6 are arranged at a position approximately 80 mm away from the edge of the front panel 1. These main stiffening ribs play a key supporting role. The first front panel stiffening ribs 5 are arranged at the upper and lower edges of the front panel 1, 80 mm away from the edge. They are connected to the second front panel stiffening ribs 6 through a welding process to ensure the integrity and stability of the structure. The third front panel stiffening ribs 7 are arranged between each bolt hole to ensure the strength and rigidity at the bolt holes. These stiffening ribs are also firmly connected to the second front panel stiffening ribs 6 through a welding process, thereby forming a complete stiffening rib reinforcement system, further improving the bearing capacity and safety of the entire front panel 1 structure.

[0034] See also Figure 4-5 Transport the prepared front panel 1, tension bolts 3, and steel backing ribs 2 to the designated construction location. First, install the U-shaped front anti-wear and anti-vibration rubber pad 12 on the back of the front panel 1. Then, stand the front panel 1 on one side of the building column 16 and buckle it onto the column 16. Using tools, adjust it to the desired elevation. Use the hold-down brackets 10 and hold-down bolts 11 to tighten the column wing panels 9 to initially secure the front panel 1. Install the tension bolts 3 with nuts on one end. Insert them through the bolt holes on both sides of the front panel 1 and connect them to the steel backing ribs 2 on the other side of the building column 16. Place the anti-wear and anti-vibration rubber pads 13 between the steel backing ribs 2 and the building. Insert two bolts at a time to maintain balance. Lightly tighten the tension bolts 3. Install all tension bolts 3 in the same manner. Then, check the position of the entire rear support. Once adjusted correctly, tighten all tension bolts 3. The attachment support is now installed. Connect the tower crane attachment rod 14 to the lug plate 4.

[0035] This standardized, rear-mounted tower crane attachment support eliminates the need for pre-embedded work, significantly simplifying the installation process of traditional tower crane attachment supports. The side wing plate clamping mechanism presses the column side wing plates 9 against the building column 16, ensuring the entire attachment support securely holds the building column 16, preventing it from shifting during use and ensuring construction safety. This also prevents damage to the building column 16 and eliminates the tedious steps of repairing the support structure after the tower crane is removed, thus eliminating the cost of repairing the construction structure. Furthermore, the attachment support is reusable, significantly improving its economic benefits. The rear-mounted support features a ribbed steel panel at the front and a steel backing rib 2 at the rear, secured by tension bolts 3. This facilitates installation and removal, improving construction efficiency. The design of the rear-mounted support has undergone rigorous safety calculations and meets safety requirements. The tower crane attached to the rear-mounted support ensures a secure and reliable installation, ensuring stability during operation and ensuring construction safety.
