Description

Technical Field

[0001] The utility model relates to the technical field of tower crane installation, in particular to a cantilever tower crane foundation structure. Background Art

[0002] In the process of construction, tower cranes are important vertical transportation equipment, and the selection of their installation location is crucial. However, in actual projects, we often encounter the problem that the space of the pedestal is small and cannot meet the installation of the embedded parts of the tower crane foundation. The traditional tower crane foundation structure usually requires a large pedestal space to install embedded parts, which makes the installation of tower cranes very difficult in some construction sites with limited space. Therefore, it is necessary to design a new cantilever tower crane foundation structure to solve the problem of insufficient pedestal space. Utility Model Content

[0003] In view of this, the utility model provides a cantilever tower crane foundation structure having

[0004] It can effectively solve the problem that the space of the pedestal is too small to accommodate the installation of embedded parts of the tower crane foundation. By adopting a cantilever design, the tower crane foundation does not need to install large-area embedded parts on the pedestal, thereby reducing the demand for pedestal space.

[0005] The utility model solves the above problems through the following technical means:

[0006] The utility model discloses a cantilever tower crane foundation structure, comprising a horizontal cantilever frame having one end fixed by a first embedded connector arranged on a pedestal and the other end suspended in the air, a diagonal support frame having one end fixed to the bottom of the suspended end of the cantilever frame and the other end fixed by a second embedded connector arranged on a side wall of the pedestal, a tide level remote reporting instrument arranged at the bottom of the suspended end of the cantilever frame, and a third embedded connector arranged on the cantilever frame for fixing the tower crane to the cantilever frame.

[0007] As a further improvement of the above technical solution, two vertical downward ladders are provided at the connection between the two side edges of the cantilever frame and the supporting platform.

[0008] Preferably, a safety rope is provided on the horizontal rod at the top of the ladder.

[0009] Preferably, one side of the ladder is fixed to the side wall of the platform by a plurality of connecting bolts.

[0010] Preferably, the side wall of the platform is provided with a fourth embedded connecting piece for fixing the ladder, and the connecting bolts pass through the bolt holes on the ladder and the fourth embedded connecting piece for connection and fixing.

[0011] As a further improvement of the above technical solution, a safety net is laid in the cavity of the cantilever frame.

[0012] Preferably, a plurality of sacrificial anodes are provided on the cantilever frame and the diagonal support frame.

[0013] Preferably, the cantilever frame and the diagonal support frame are both formed by welding steel box girders.

[0014] Preferably, a fifth embedded connector is provided on the upper portion of the support platform for limiting and fixing the end of the horizontal cantilever frame.

[0015] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0016] The cantilever tower crane foundation structure of the utility model is prepared by welding the cantilever frame and the diagonal support frame into an integral frame structure in advance in a processing site. After the concrete strength of the pedestal reaches the design strength requirement, the frame structure is welded to the first embedded connector and the second embedded connector on the pedestal to form a whole as a tower crane foundation. The structure is simple and convenient to install and can be quickly disassembled and reused, thereby improving construction efficiency and reducing engineering costs. The tower crane can be installed when the pedestal space is small, successfully solving the problem that the embedded parts of the tower crane foundation cannot be installed due to the small effective installation space of the pedestal. The tower crane is fixed to the cantilever frame by the third embedded connector provided on the cantilever frame to ensure the stability and safety of the tower crane. Moreover, the tide level telemeter located at the bottom of the cantilever frame can monitor the real-time tide level there. By analyzing the tide level change curve, the best time for construction can be selected, thereby improving construction efficiency and construction safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0021] The utility model will be described in detail below with reference to the accompanying drawings. Figure 1 As shown: the cantilever tower crane foundation structure described in this embodiment includes a horizontal cantilever frame 4 fixed at one end by a first embedded connector 3 arranged on the base 1 and suspended at the other end, a diagonal support frame 6 fixed at one end to the bottom of the suspended end of the cantilever frame and fixed at the other end by a second embedded connector 5 arranged on the side wall of the base 1, a tide level remote reporting instrument 7 arranged at the bottom of the suspended end of the cantilever frame, and a third embedded connector 8 arranged on the cantilever frame for fixing the tower crane 2 to the cantilever frame.

[0022] The cantilever tower crane foundation structure described in this embodiment has a simple and convenient structure for installation, can be quickly disassembled and reused, thereby improving construction efficiency and reducing engineering costs. The tower crane 2 can be installed when the space on the base 1 is relatively small, successfully solving the problem that the embedded foundation parts of the tower crane 2 cannot be installed due to the small effective installation space on the base 1. The tower crane 2 is fixed to the cantilever frame by a third embedded connector 8 provided on the cantilever frame, thereby ensuring the stability and safety of the tower crane 2. Moreover, the tide level remote reporting instrument 7 located at the bottom of the cantilever frame can monitor the real-time tide level there, and the best time for construction can be selected by analyzing the tide level change curve, thereby improving construction efficiency and construction safety.

[0023] The dimension design of the cantilever tower crane foundation structure described in the present embodiment is as follows: the lengths of the cantilever frame and the diagonal brace frame 6 are determined according to the installation position of the tower crane 2. In addition, according to the model and weight of the tower crane 2, the steel specifications of the cantilever frame and the diagonal brace frame 6 are determined through structural design calculations to ensure that the stability of the cantilever tower crane foundation structure described in the present embodiment meets the requirements of the installation and use of the tower crane 2.

[0024] During construction, the cantilever frame and the diagonal support frame 6 are first welded and processed into an integral frame structure in the processing site in advance. According to the frame structure, the connecting embedded parts are set in advance at the corresponding positions of the pedestal 1 structure before the concrete of the pedestal 1 is poured. Then, after the concrete strength reaches the design strength, the processed frame structure is welded and connected with the first embedded connecting parts 3 and the second embedded connecting parts 5 on the pedestal 1 to form a whole as the foundation of the tower crane 2. Finally, the tower crane 2 is fixed to the cantilever frame by the third embedded connecting parts 8 provided on the cantilever frame to complete the installation of the foundation section of the tower crane 2. After the work of the tower crane 2 is completed, the foundation section of the tower crane 2 is quickly separated from the cantilever tower crane 2 foundation frame structure by removing the connecting nut; in addition, the connection part between the tower crane 2 foundation and the pedestal 1 embedded parts is cut off by gas cutting, so that the cantilever tower crane foundation frame structure can be quickly disassembled and reused.

[0025] To facilitate installation, as a further improvement of the above technical solution, two vertical downward ladders 9 are provided at the connection between the two side edges of the cantilever frame and the base 1. After fixing the cantilever frame and the ladders 9, the construction workers can go down through the ladders 9, so as to conveniently connect and fix the lower components, which greatly reduces the difficulty of connecting and fixing the lower components.

[0026] As a preferred implementation of the above technical solution, a safety rope (not shown in the figure) is provided on the horizontal rod at the top of the ladder 9. After being connected to the construction workers, the safety rope can be provided to the construction workers descending from the ladder 9, thereby improving the construction safety.

[0027] As a preferred implementation of the above technical solution, one side of the ladder 9 is fixed to the side wall of the platform 1 by a plurality of connecting bolts 10, which can not only improve the connection strength of the ladder 9, but also support the cantilever frame in the vertical direction, further improve the installation stability of the cantilever frame, and thus improve construction safety.

[0028] In order to facilitate installation and improve the efficiency of connection and disassembly, as a preferred implementation of the above technical solution, the side wall of the base 1 is provided with a fourth embedded connecting piece 11 for fixing the ladder 9, and the connecting bolts 10 pass through the bolt holes on the ladder 9 and the fourth embedded connecting piece 11 for connection and fixing.

[0029] As a further improvement of the above technical solution, a safety net (not shown in the figure) is laid in the cavity of the cantilever frame, thereby further improving the construction safety of the cantilever tower crane foundation structure described in this embodiment, protecting the construction workers thereon, increasing the platform area, and making it more convenient to use.

[0030] As a preferred implementation of the above technical solution, a plurality of sacrificial anodes 12 are provided on the cantilever frame and the diagonal support frame 6. The provision of the plurality of sacrificial anodes 12 can provide cathodic protection for the cantilever tower crane foundation structure described in this embodiment, thereby avoiding corrosion and damage to the tower crane foundation structure, which not only extends the service life but also further improves the safety of construction.

[0031] As a preferred implementation of the above technical solution, the upper part of the base 1 is provided with a fifth embedded connector 13 which is useful for limiting and fixing the end of the horizontal cantilever frame 4. The horizontal cantilever frame 4 is fixedly connected in the vertical direction and the horizontal direction respectively by the fifth embedded connector 13 and the first embedded connector 3, which further ensures the firmness of the installation and thus ensures the safety of the construction.

[0032] In this embodiment, the cantilever frame and the diagonal support frame 6 are both formed by welding steel box beams.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
