Description

Technical Field

[0001] The present application relates to the field of building construction technology, and in particular to a walking tower crane foundation on steps. Background Art

[0002] Tower cranes are indispensable equipment in construction projects. They play an extremely important role in construction and are the most important vertical transportation machinery. They are often used in the construction sites of large buildings such as high-rise buildings, bridges, water conservancy projects and stadiums.

[0003] In high-rise buildings, tower cranes can help workers complete aerial work and carry construction materials and equipment; in bridge and water conservancy projects, tower cranes can be used for lifting heavy objects such as the lifting and assembly of bridge piers and the construction of water conservancy dams; in stadium projects, tower cranes can be used for the lifting and transportation of large components. Therefore, the reasonable choice of tower cranes will bring direct benefits to construction safety and progress, and can save secondary transportation and save costs.

[0004] In actual operations, common lifting and hoisting equipment include crawler tower cranes and fixed tower cranes. Fixed tower cranes have the advantages of good stability and strong carrying capacity, and are suitable for long-term operations in large projects. However, their disassembly and assembly are relatively complicated and cumbersome, and they are difficult to move. Holes need to be reserved at various implementation locations of the construction project, and thus they need to occupy a larger construction space. Crawler tower cranes have the advantage of high flexibility that fixed tower cranes do not have. They can be flexibly moved according to construction needs and are very convenient to use. Therefore, they are widely used in various construction projects. However, for full basement venues, on the one hand, the carrying capacity of the venue core is limited, and thus crawler tower cranes cannot be used. On the other hand, the venue stands have more stages, and crawler tower cranes are difficult to move flexibly on the stages. Utility Model Content

[0054] The implementation principle of a walking tower crane foundation on a step in Example 1 of the present application is as follows: when the walking tower crane foundation is used, first determine a step surface as the installation step surface 5, and the bottom working surface as the bottom installation surface 6. There is a height difference between the installation step surface 5 and the bottom installation surface 6. Then, a plurality of high-part support seats 1 are arranged at intervals along the length direction of the installation step surface 5 on the installation step surface 5, and each high-part support seat 1 is arranged on the structural column of the installation step surface 5. A plurality of bottom support seats 2 are arranged at intervals along the length direction of the bottom installation surface 6 on the bottom installation surface 6, and each bottom support seat 2 is arranged on the structural column of the bottom installation surface 6. At this time, the tops of the plurality of high-part support seats 1 and the tops of the plurality of bottom support seats 2 are all at In the same horizontal plane; when the high support seat 1 and the bottom support seat 2 are both installed, slide rails 3 are installed on the top of multiple high support seats 1, and slide rails 3 are installed on the top of multiple bottom support seats 2. The two slide rails 3 are parallel and in the same horizontal plane. The high support seat 1 and the bottom support seat 2 serve as support points for the slide rails 3, so that there is a corresponding slide rail 3 on the installation step surface 5 and the bottom installation surface 6, and the slide rails 3 are arranged along the length direction of the step surface; thereafter, the mounting seat 4 is overlapped on the support seat. At this time, the two sets of rollers 8 are respectively located on the corresponding slide rails 3, and the construction of the walking tower crane foundation is completed; when the walking tower crane foundation is installed, the tower crane is connected to the foundation section 7 to complete the installation of the tower crane.

[0055] The cooperation of various components in the above process can complete the construction of the walking tower crane foundation. There is no need to drill holes on the steps during the construction process, thereby avoiding damage to the step structure. Through the cooperation of the slide rail 3 and the mounting seat 4, the tower crane installed on the walking tower crane foundation can be moved on the steps. The tower crane can be flexibly moved according to construction needs. It is easy to use and has a wide range of uses. It can be applied to projects where the construction ground changes frequently. In addition, the overall structure of the walking tower crane foundation is simple, which can save construction space on the construction site and has the advantage of easy disassembly and assembly.

[0056] Example 2

[0057] The difference between Example 2 and Example 1 is that: referring to FIG. 8 , the first base column 18 is provided with a cover plate 21 , and the first base column 18 , the cover plate 21 and the bottom of the first support rod 17 are surrounded to form a pouring cavity 22 for pouring concrete.

[0058] The implementation principle of Example 2 is: when connecting the upper support seat 1 with the first base column 18, a cover plate is laid on the first base column 18, and then the upper support seat 1 is placed on the first base column 18. At this time, a casting cavity 22 is formed between the first base column 18, the cover plate and the upper support seat 1. By pouring concrete into the casting cavity 22, the upper support seat 1 can be fixed on the first base column 18, so that a stable connection is formed between the upper support seat 1 and the first base column 18.

[0059] Example 3

[0060] The difference between Example 3 and Example 1 is that: Fig. 9 The bottom support seat 2 includes a fixed rod 25 and a movable rod 26, which are coaxially slidably connected. The movable rod 26 is provided with first positioning holes 27 spaced apart along the length direction. The fixed rod 25 is provided with a second positioning hole, and a positioning pin 28 is passed through the second positioning hole. The positioning pin 28 is simultaneously passed through any of the first positioning holes 27.
