DETAILED DESCRIPTION

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the present application discloses a tower crane foundation structure. Referring to Figure 1 , Figure 2 and Figure 3 ​As shown, a tower crane foundation structure includes a foundation 1, a foundation platform 2 fixedly installed on the upper surface of the foundation 1, the foundation platform 2 being a square structure, and reinforcement frames 3 installed at the four corners of the foundation platform 2, the reinforcement frames 3 being fixedly connected to the foundation platform 2, and extension supports 4 installed on both sides of the reinforcement frames 3, one end of the extension supports 4 being attached to the reinforcement frames 3, and the extension supports 4 being fixedly connected to the reinforcement frames 3 by bolts. By fixing the foundation platform 2 on the foundation 1, it can be used as the mounting base for the tower crane when in use. The foundation platform 2 is designed with a square structure, which facilitates the installation of reinforcing frames 3 at its four corners. The reinforcing frames 3 can be used to hold and fix the foundation platform 2, and can also be used to shield and protect the square structure of the foundation platform 2, ensuring greater safety during use and preventing damage or cracking due to external impacts. This greatly increases the safety of the foundation platform 2. At the same time, by installing extension supports 4 on both sides of the reinforcing frames 3, the extension supports 4 can be used to support the foundation 1 around its perimeter, which not only increases the stability of the foundation 1, but also facilitates the installation of diagonal frames on the extension supports 4, which can be used to support the crane frame, thereby further increasing the stability during use. The extension supports 4 are fixedly connected to the reinforcing frames 3 with bolts, which facilitates quick connection between the two and allows for quick disassembly when not in use, making it very convenient to use.

[0032] Reference Figure 1 and Figure 2 As shown, the lower end of the foundation 1 is set on a sunken base 11, and an internally threaded pipe 12 is installed on the upper surface of the sunken base 11. The lower end of the internally threaded pipe 12 is fixedly installed in the sunken base 11, and the head of the internally threaded pipe 12 passes through the foundation platform 2. By setting the sunken base 11 at the lower end of the foundation 1, the sunken base 11 is fixedly installed at a depth below the ground. Then, the internally threaded pipe 12 is fixedly installed through the sunken base 11, ensuring that the lower end of the internally threaded pipe 12 is poured into the sunken base 11, while the upper end can protrude from the upper surface of the foundation 1. Then, the foundation platform 2 on the foundation 1 is poured. This ensures that the internally threaded pipe 12 can be poured into the foundation platform 2, and the head of the internally threaded pipe 12 can protrude from the foundation platform 2. After the pouring is completed, the internally threaded pipe 12 can be cut to ensure that the top of the internally threaded pipe 12 is flush with the upper surface of the foundation platform 2, so that the reinforcement frame 3 can be better connected and fixed by threads.

[0033] Reference Figure 1 and Figure 3As shown, the foundation platform 2 includes a base 21 and connecting bolts 22. The connecting bolts 22 are evenly installed on the base 21, with the lower end of the connecting bolts 22 cast into the base 21 and the head of the connecting bolts 22 extending from the upper surface of the base 21. By designing the foundation platform 2 into a structure where the base 21 and the connecting bolts 22 cooperate, the base 21 can be used as the base of the foundation platform 2 for easy use. Then, several connecting bolts 22 are cast and fixed in the base 21, which facilitates better assembly and fixation of the tower crane later.

[0034] Reference Figure 1 and Figure 4 As shown, the reinforcing frame 3 includes a right-angled side plate 31 and a top plate 32. The top plate 32 is installed on the upper surface of the right-angled side plate 31, and the top plate 32 and the right-angled side plate 31 are integrally formed. By designing the reinforcing frame 3 into a structure in which the right-angled side plate 31 and the top plate 32 cooperate, it can be positioned and engaged on the sides of the four corners of the base platform 2 when in use. At the same time, the top plate 32 is fixedly installed on the upper surface of the corners. Thus, the corners of the base platform 2 can be protected by the right-angled side plate 31 and the top plate 32, ensuring the safety of the base platform 2 during use. The upper surface of the top plate 32 has a center hole 321 corresponding to the internally threaded tube 12, and the top plate 32 is fixedly connected to the internally threaded tube 12 by locking bolts 322. By setting a center hole 321 on the upper end face of the top plate 32, after the reinforcement frame 3 is fixedly installed on the corner of the base platform 2, it can be aligned with the head of the internal threaded tube 12 through the center hole 321. This makes it convenient for the locking bolt 322 to pass through the center hole 321 from the top and connect with the internal threaded tube 12, ensuring that the reinforcement frame 3 can be stably fixed on the corner of the base platform 2.

[0035] Reference Figure 1 and Figure 5As shown, the extension support 4 includes a base plate 41 and a support plate 42. The support plate 42 is installed on the lower end face of the base plate 41 and is vertically fixed to the base plate 41. By designing the extension support 4 into a structure in which the base plate 41 and the support plate 42 cooperate, it is easy to use. The base plate 41 can be connected to the top plate 32 on the reinforcement frame 3. The cooperation installation allows one end of the base plate 41 to be attached to the lower end face of the top plate 32. Then, the support plate 42 is set to ensure support on the upper end face of the base platform 2, thereby ensuring the stable use of the base plate 41. The base plate 41 can stably support the reinforcement frame 3, thereby increasing the stability of the base platform 2. The base plate 41 can also be used to install a support bracket, which is convenient for the stable fixing of the diagonal brace on the base plate 41 when the crane needs to be reinforced. The support plate 42 includes a vertical plate 421 and foot plates 422. The foot plates 422 are installed at both ends of the lower end face of the vertical plate 421 and are integrally formed with the vertical plate 421. By designing the support plate 42 into a structure where the vertical plate 421 and foot plates 422 cooperate, the vertical plate 421 can support the base plate 41 when in use, and the foot plates 422 at both ends of the vertical plate 421 ensure stable support on the base platform 2 during use. Connecting through holes 411 are provided at the four corners of the base plate 41, and mating holes 323 corresponding to the connecting through holes 411 are provided on the upper end face of the top plate 32. By providing connecting through holes 411 on the base plate 41, the connecting through holes 411 can be aligned with the mating holes 323 during use, and bolts can be used to better fix the base plate 41 and the top plate 32 together during use.

[0036] The implementation principle of a tower crane foundation structure according to an embodiment of this application is as follows: During construction, a deep hole is drilled below the foundation 1, and then an internally threaded pipe 12 is placed in the deep hole and poured to a certain height. After the pouring is completed, backfilling is carried out after a period of time. After backfilling is completed, a mold frame for the foundation platform 2 can be set up on the upper end of the foundation 1, and then the foundation platform 2 can be poured. During the pouring of the foundation platform 2, connecting bolts 22 need to be inserted evenly. After the foundation platform 2 solidifies, the internally threaded pipe 12 can be cut, and then a reinforcing frame 3 can be installed at its four corners. After the reinforcing frame 3 is fixed on the foundation platform 2, the reinforcing frame 3 can be installed.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
