[0028] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following is for reference. Figures 1-5 This invention describes a protective assembly 300 for a tower crane foundation used in tower construction, according to an embodiment of the present invention. A tower crane is a type of tower lifting machinery, also known as a tower hoist.

[0030] Specifically, according to an embodiment of the present invention, a protective component 300 for a tower crane foundation for tower construction includes a tower foundation 220 and a concrete tower, wherein the concrete tower is disposed on the tower foundation 220.

[0031] For example, in some embodiments, the tower foundation 220 can be a solid structure. Optionally, the interior of the tower foundation 220 can also be a hollow frustum-shaped structure. This application does not limit the specific structural form of the tower foundation 220, and it can be adapted as needed in practical applications.

[0032] The cross-section of the concrete tower can be circular or polygonal. When the cross-section of the concrete tower is polygonal, the radial dimension of the concrete tower refers to the diameter of the largest circumscribed circle of the concrete tower, which is understandable to those skilled in the art.

[0033] The tower crane foundation 100 can be located on one radial side of the outer surface 221 of the tower foundation 220. This is illustrative and not restrictive. Figure 2 The image shows an embodiment in which the tower crane foundation 100 is located on the outer side 221 of the tower foundation 220 along the radial left side.

[0034] The tower crane foundation 100 includes a bottom support 1, a connecting flange 2, and high-strength bolts 3. Specifically, the bottom support 1 and the tower foundation 220 can be integrally cast, which helps reduce the workload of construction operations for the tower crane foundation 100 and thus shortens the construction period. The connecting flange 2 can be located on the upper surface 11 of the bottom support 1, allowing for further connection of the tower crane 101 to the tower crane foundation 100. A portion of the high-strength bolts 3 are pre-embedded in the bottom support 1, and the high-strength bolts 3 are connected to the connecting flange 2. Multiple high-strength bolts 3 are arranged at intervals. Therefore, the tower crane foundation 101 not only facilitates the installation and dismantling of the tower crane 101 but also improves the installation stability and reliability of the tower crane 101.

[0035] According to an embodiment of the present invention, the tower crane foundation 100 for tower construction is provided on one radial side of the outer surface 221 of the tower foundation 220, and the bottom support 1 is integrally cast with the tower foundation 220. This ensures the integrity of the tower crane foundation 100, improves the load-bearing capacity of the tower crane foundation 100, and thus ensures the safety and reliability of the tower crane 101.

[0036] Reference Figure 4 and Figure 5 According to an embodiment of the present invention, a protective component 300 for tower crane foundation construction is provided above the bottom support 1, and the protective component 300 can be connected to the high-strength bolt 3, so that the high-strength bolt 3 can be protected by the protective component 300.

[0037] According to an embodiment of the present invention, the protective component 300 for the tower crane foundation for tower construction can prevent the high-strength bolts 3 embedded in the bottom bearing platform 1 from rusting and being impacted after the tower crane 101 is disassembled from the tower foundation 100. Thus, the high-strength bolts 3 can be protected. Therefore, when the tower is in normal use, the protective component 300 can protect the high-strength bolts 3.

[0038] Combination Figure 4 and Figure 5 According to some embodiments of the present invention, the protective assembly 300 may include multiple sets, each set of the protective assembly 300 including: a top cover plate 320 and multiple bolt caps 310. Specifically, the bolt caps 310 can be fitted over the upper end of the high-strength bolts 3, and the lower end of the bolt caps 310 can abut against the upper surface of the connecting flange 2. The bolt caps 310 are arranged in a one-to-one correspondence with the high-strength bolts 3. The top cover plate 320 is disposed on top of the multiple bolt caps 310, and the relative positions of the top cover plate 320 and the multiple bolt caps 310 are fixed. Thus, the protective assembly 300 can achieve protection of the tower crane foundation 100.

[0039] Furthermore, the bolt cap 310 can be a rubber or plastic part, and the bolt cap 310 is interference-fitted with the high-strength bolt 3. Thus, the fit between the bolt cap 310 and the high-strength bolt 3 facilitates a reliable connection between them, thereby providing better protection for the high-strength bolt 3.

[0040] Optionally, refer to Figure 5 The top cover plate 320 can be constructed in an umbrella shape with a central upward convexity, so that the top cover plate 320 protrudes above the ground after soil is filled. The top cover plate 320 includes a plate body 321 and a protrusion 322, the protrusion 322 being located on the upper surface of the plate body 321 and protruding upward. Thus, when soil is filled on the tower crane foundation 100, the top of the top cover plate 320 can protrude above the ground, thereby serving as a certain identification function, making it easier for construction personnel to quickly locate the tower crane foundation 100 and facilitating construction.

[0041] Because the tower crane 101 bears a large load, its safety and reliability must be ensured. According to some embodiments of the present invention, the portion of the high-strength bolt 3 embedded in the bottom foundation 1 is also connected to a reinforcing member 4. The reinforcing member 4 is arranged perpendicular to the high-strength bolt 3 to improve the anchoring capacity of the tower crane foundation 100. Therefore, by providing a reinforcing member 4 on the high-strength bolt 3, the anchoring capacity of the tower crane foundation 100 is improved, thereby enhancing the safety of the tower crane 101.

[0042] Furthermore, the reinforcing member 4 is a steel bar pre-embedded in the bottom bearing platform 1, which can be welded to the high-strength bolt 3. The steel bar can be a short bar, which helps reduce costs. Even further, the diameter of the high-strength bolt 3 is D, and the length L of the steel bar is in the range of 4D-10D. Therefore, by setting the reinforcing member 4, such as a steel bar, not only can the load-bearing capacity of the tower crane foundation 100 be improved, but costs can also be reduced.

[0043] The length L of the reinforcing bar can be 4D, 6D, 8D, or 10D, etc., and the present invention does not impose a specific limitation thereon. Of course, without considering cost, the length of the reinforcing bar can be appropriately increased, and in some embodiments, the reinforcing member 4 can also be other structural forms, which is understandable to those skilled in the art.

[0044] Reference Figure 2 and Figure 3 According to some embodiments of the invention, in the axial direction of the tower (e.g.) Figure 3 As shown in the vertical direction, the outer surface 12 of the bottom support 1 can be flush with the outer peripheral surface 222 of the tower foundation 220. This ensures good consistency between the tower crane foundation 100 and the tower foundation 220, and also results in an aesthetically pleasing appearance.

[0045] According to some embodiments of the present invention, the upper surface 11 of the bottom support 1 may be set lower than the upper surface 223 of the tower foundation 220; the distance between the upper surface 11 of the bottom support 1 and the upper surface 223 of the tower foundation 220 is 200-300mm. Therefore, when the tower crane 101 is installed on the tower crane foundation 100, the tower crane foundation 100 can be covered with soil, thus concealing the tower crane foundation 100 and resulting in an aesthetically pleasing appearance.

[0046] The distance between the upper surface 11 of the bottom support 1 and the upper surface 223 of the tower foundation 220 can be 200mm, 230mm, 250mm, 280mm or 300mm, etc., and the present invention does not make a specific limitation thereto.

[0047] In some alternative embodiments, the upper surface 11 of the bottom support 1 may also be flush with the upper surface 223 of the tower foundation 220.

[0048] Furthermore, referring to Figure 3A radiator foundation 5 can also be provided on one radial side of the outer surface 221 of the tower foundation 220. A radiator can be installed on the radiator foundation 5. The radiator foundation 5 can be set adjacent to the tower crane foundation 100. The upper surface 51 of the radiator foundation 5 can be set higher than the upper surface 11 of the bottom support 1, and the upper surface 51 of the radiator foundation 5 can be flush with the upper surface 223 of the tower foundation 220. This makes the arrangement of the tower crane foundation 100 and the radiator foundation 5 on the tower foundation 220 more compact and aesthetically pleasing.

[0049] Furthermore, referring to Figure 3 In the longitudinal section of the tower, the tower crane foundation 100 is constructed in a trapezoidal shape, and the radiator foundation 5 is constructed in a triangular shape. This makes the arrangement of the tower crane foundation 100 and the radiator foundation 5 on the tower foundation 220 more compact.

[0050] In some embodiments of the present invention, reference is made to... Figure 2 and Figure 3 The bottom of the tower foundation 220 may also be provided with a foundation base 210, which can be integrally cast with the tower foundation 220. The foundation base 210 is constructed as a cone that tapers inward from top to bottom. The maximum dimension of the foundation base 210 in the lateral direction can be greater than the maximum dimension of the tower foundation 220 in the lateral direction. This helps to improve the stability of the tower foundation 220 to a certain extent, thereby further improving the reliability of the concrete tower.

[0051] According to some embodiments of the present invention, the connecting flanges 2 include at least four, which are arranged in a quadrilateral shape, such as a rectangle. Thus, a reliable connection between the tower crane foundation 100 and the tower crane 101 can be easily achieved through the connecting flanges 2.

[0052] According to some embodiments of the present invention, the concrete tower can be constructed by splicing together multiple arc-shaped concrete tower segments. This facilitates the construction of the concrete tower and helps reduce costs.

[0053] The concrete tower can be connected to the tower foundation 220 via connectors such as high-strength bolts. In some alternative embodiments, the concrete tower can also be a segmented straight tower.

[0054] According to an embodiment of the present invention, the tower crane foundation 100 for tower construction can ensure the integrity of the tower crane foundation 100, reduce the construction workload of the tower crane foundation 100, and improve the load-bearing capacity of the tower crane foundation 100 by setting the tower crane foundation 100 on the tower foundation 220.

[0055] Other configurations and operations of the tower crane foundation 100 and protective components 300 for tower construction according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
