Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower crane erection equipment, specifically a tower crane support frame. Background Technology
[0002] Tower cranes are among the most frequently used construction tools on construction sites, possessing powerful lifting and assembly capabilities for cargo handling and high-altitude transportation. The tower crane erection process involves building a foundation on the ground, upon which the tower crane frame is then constructed to ensure overall stability. During the frame construction, the foundation plate is attached to cast-in-place bolts in the ground before further erection. These bolts are cast into the ground during the concrete pouring process to ensure optimal tensile strength. When installing the concrete pouring bolts, it is necessary to ensure that the bolts are vertical to guarantee the stability and flatness of the subsequent foundation slab frame construction. However, in the early stages of foundation pouring, the concrete is in a fluid state. Under these conditions, the installed pouring bolts are prone to tilting under external forces, which may prevent them from providing a more stable platform for the subsequent foundation slab installation. This necessitates complex operations such as shim installation and subsequent measurements for the bolts at that location, which is detrimental to the effective installation of the tower crane.
[0003] To address the aforementioned issues, a tower crane support frame is designed to assist in positioning the bolts of the tower crane base. Simultaneously, this positioning process does not affect the bolts' proper fixation within the concrete, ensuring the base bolts remain vertical and do not tilt excessively, thus guaranteeing better stability for the subsequently installed tower crane. Utility Model Content
[0004] The purpose of this utility model is to provide a tower crane support frame that can help position the bolts of the tower crane base without affecting the normal fixation of the bolts in the concrete, thereby ensuring that the base bolts are vertical and do not tilt at an excessive angle.
[0005] To achieve the above objectives, this utility model employs the following technical solution:
[0006] A tower crane support frame includes a support frame body, which is a hollow, non-enclosed structure, and at least three inner support members are provided on the support frame body, each of which is fixedly connected to the support frame body.
[0007] The support frame includes a frame and a surrounding net. The frame is a hollow structure with alternating through holes to form a hollow, non-closed structure, and the surrounding net is positioned between adjacent frames.
[0008] The support frame has a conical structure, and an upper fixing frame and a lower fixing frame are respectively provided at the upper and lower ends of the support frame. The upper fixing frame and the lower fixing frame respectively limit the diameter of the upper and lower ends of the support frame.
[0009] The inner support component includes a connecting rod and a semi-enclosed collar. The outer end of the connecting rod is connected to the inner end face of the support frame, and the inner end of the connecting rod is connected to the semi-enclosed collar.
[0010] The support frame and internal support components are both made of non-elastic deformation materials.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] Traditional cast-in-place bolts, lacking any restraint after concrete pouring, are prone to tilting and angular changes under external forces, hindering the effective construction of the platform above them. This device, however, employs a support frame with at least three internal supports. The support frame restrains the overall position of the bolts, while the three internal supports provide three-point restraint, ensuring the bolts do not tilt during concrete curing and guaranteeing a more stable platform built upon them.

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0019] Before any tower crane erection can begin, a tower crane base must be constructed to ensure overall stability. During concrete pouring for the tower crane base, the orientation of the fixing bolts must be carefully controlled to maintain stability during the subsequent base construction. However, during and after concrete pouring, external forces can easily cause the helical screws to tilt, affecting the proper securing of the tower crane base.
[0020] Therefore, based on the aforementioned technical problems and the issues pointed out in the background art, a tower crane support frame is designed as follows:
[0021] The system includes a support frame 1, which is a hollow, non-enclosed structure. At least three inner support members 2 are provided on the support frame 1, each of which is fixedly connected to the support frame 1. The support frame 1 is used to restrict the overall position of the casting bolt, ensuring that the overall position of the casting bolt does not easily change. The presence of at least three inner support members 2 further restricts the specific angular position of the casting bolt, effectively limiting its movement. Because at least three inner support members 2 (three-point limiting) are required to limit the position of the casting bolt, this system necessitates the use of at least three inner support members 2. However, multiple inner support members 2 can also be used to achieve better fixation of the casting bolt's position. However, it should be considered that if the support frame 1 occupies too much of the concrete and the area occupied by the casting bolts, the concrete may not be able to effectively fix the casting bolts, thus defeating the purpose of the casting bolts. Therefore, the support frame 1 is designed as a hollow, non-enclosed structure. This allows concrete to enter the hollow structure of the support frame 1 even after its installation, preventing it from occupying space. Furthermore, after fusing with the concrete, the support frame 1 also acts as a reinforcing rib, strengthening the concrete base and preventing any issues with the proper fixing of the casting bolts.
[0022] The above structure is further designed and optimized as follows:
[0023] The support frame 1 includes a frame body and a surrounding mesh 3. The frame body is a hollow structure with alternating through holes, forming a hollow, non-enclosed structure. The surrounding mesh 3 is positioned between adjacent frame bodies. Specifically, the hollow, non-enclosed structure of the support frame 1, with its alternating through holes, allows concrete to penetrate the hollow structure even when the support frame 1 is installed outside the casting bolt, ensuring seamless integration between the support frame 1 and the concrete and preventing interference with the bolt's fixation. The surrounding mesh 3 acts as a reinforcing rib, ensuring better strength of the concrete around the casting bolt and further guaranteeing the bolt's stability after casting.
[0024] The support frame 1 has a conical structure 4, and an upper fixing frame 5 and a lower fixing frame 6 are respectively provided at the upper and lower ends of the support frame 1. The upper fixing frame 5 and the lower fixing frame 6 limit the diameter of the upper and lower ends of the support frame 1. Because the conical structure 4 has a relatively stable shape, it can ensure that the bottom of the support frame 1 can better support the overall device. Furthermore, the upper fixing frame 5 and the lower fixing frame 6 limit the upper and lower ends of the support frame 1, thereby ensuring that the support frame 1 will not impose too much restriction on the casting bolts. The inner support component 2 includes a connecting rod 7 and a semi-enclosed collar 8. The outer end of the connecting rod 7 is connected to the inner end face of the support frame 1, and the inner end of the connecting rod 7 is connected to the semi-enclosed collar 8. The semi-enclosed collar 8 can easily surround the casting bolts and facilitate the operation of the workers.
[0025] Both the support frame 1 and the inner support component 2 are made of non-elastic deformation materials to ensure that the concrete strength is not affected while effectively supporting the casting bolts.
[0026] Therefore, a tower crane support frame can help position the bolts of the tower crane base without affecting the normal fixation of the bolts in the concrete, thus ensuring that the base bolts are vertical and do not tilt at an excessive angle.
