[0028] This utility model provides an improved method for ultra-long attachment of tower cranes in building construction projects. The technical solution of this utility model is as follows:
[0029] like Figures 1-6 As shown, an ultra-long tower crane attachment for a building construction project includes a tower crane standard section 1, a floor slab 2, and an ear plate 4. An attachment frame 6 is fixedly installed on the outside of the tower crane standard section 1, which is conducive to the normal operation of the tower crane and the stability of the attachment system. It also includes a connecting component 7.
[0030] Connecting steel plate 5 is fixedly installed on one side of the bottom of floor slab 2;
[0031] The lattice tie rod 14 is provided in two sets. One set of lattice tie rod 14 is provided between ear plate 1 4 and floor slab 2, and the other set of lattice tie rod 14 is provided between ear plate 1 4 and attachment frame 6, so as to meet the strength and stability required for construction and ensure construction quality.
[0032] The connecting component 7 includes an ear plate 8 disposed on the outside of the floor slab 2, which plays a good auxiliary role in the installation of the lattice tie rod 14.
[0033] Furthermore, the connecting steel plate 5 is fitted with a lattice cantilever 3 by bolt threads, and multiple high-strength bolts 11 are installed on the upper threads of the ear plate 4. The lattice cantilever 3 is connected to the bottom threads of the ear plate 4 by the high-strength bolts 11. One end of each set of lattice tie rods 14 is connected to the ear plate 4 by the high-strength bolts 11, which improves the tightness of the connection, ensures the normal operation of the tower crane, and helps to speed up the construction speed and process.
[0034] As a further embodiment of this utility model, a plurality of high-strength bolts 9 are threaded on the ear plate 2, and a pad 10 is provided on one side of the floor slab 2. The high-strength bolts 9 penetrate the floor slab 2 and are connected to the pad 10. The ear plate 2 is connected to one end of one set of lattice tie rods 14 through the high-strength bolts 9. The stability and firmness of the connection between the tie rod and the floor slab 2 are improved by the high-strength bolts.
[0035] Furthermore, one end of another set of lattice-type tie rods 14 is threaded with a high-strength bolt 3 12. One side of the attachment frame 6 is connected to another set of lattice-type tie rods 14 through the high-strength bolt 3 12. Multiple high-strength bolts 4 13 are threaded between the attachment frames 6. The tie rods and bolts make the overall structure more stable in force transmission, extend the service life of the device, and enhance its practicality.
[0036] The specific working method is as follows: First, the longest tie rod in this structure is 13.4m long, and the horizontal cantilever length is 5m. Both the cantilever and the tie rod adopt a lattice structure composed of four angle steel branches. One end of the cantilever and one set of tie rods are connected to ear plate 4. Then, the other end of the cantilever is connected to floor slab 2. The other ends of the two sets of tie rods are connected to floor slab 2 and attachment frame 6 respectively, so that the tower crane can maintain stable operation and complete construction under adverse weather conditions. In addition, ear plate 8 is connected to the beam of floor slab 2 with high-strength bolts. A whole piece of steel pad 10 is used behind to increase the stress area and improve the connection reliability.
[0037] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
