Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and relates to an extra-long tower crane wall attachment system and an installation and disassembly method thereof. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". It is connected in length (height) section by section (referred to as "standard section") and is mainly used to lift construction materials such as steel bars, wooden slats, concrete, steel pipes, etc.

[0003] There are many ways to attach a tower crane to a structure, each tailored to the specific project needs and constraints. In some cases, during high-rise construction, a tower crane needs to be installed on the ground, such as outside the structural frame. Normally, the tower crane is supported by a wall attachment on the outer frame structure. However, if the outer frame construction lags behind the core wall by several layers, the tower crane will struggle to support the core wall construction. Therefore, the wall attachment device must be temporarily supported on the outer wall of the core wall. This results in an excessively long temporary wall attachment, which must be repeatedly installed and removed as construction progresses. This is inefficient and labor-intensive. Therefore, we have proposed an extra-long tower crane wall attachment system and its installation and removal method to address these issues. Summary of the Invention

[0004] In view of this, in order to solve the problem that the outer frame construction lags behind and the core tube has too many layers during current construction, it is necessary to temporarily support the wall attachment device on the outer wall of the core tube, resulting in an extra-long temporary wall attachment and the need to repeatedly install and dismantle the extra-long wall attachment system as the construction progresses, which has low efficiency, high construction risk, and a large amount of manual labor, the present invention provides an extra-long wall attachment system for a tower crane and its installation and disassembly method.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0010] Furthermore, the embedded mechanism includes an embedded plate, which is embedded in one side of the building, and one side of the embedded plate is fixedly connected with a plurality of fixing bolts.

[0011] Furthermore, the connecting assembly includes a first connecting frame and a second connecting frame, an extension frame is fixedly connected between the first connecting frame and the second connecting frame, a threaded rod is inserted into one end of the first connecting frame, the circumferential thread of the threaded rod is connected to two fixing nuts, the two fixing nuts are respectively located on both sides of one end of the first connecting frame, one end of the threaded rod is fixedly connected to the second connecting seat, and the second connecting seat is movably connected to the through hole on one of the sliding sleeves through a pin shaft.

[0012] Furthermore, the bottoms of the first connecting frame and the second connecting frame are fixedly connected to fixed seats, and the two diagonal support frames are rotatably connected to the two fixed seats respectively. The bottom of one of the diagonal support frames is rotatably connected to the first connecting seat, and the first connecting seat is movably connected to the through hole on the other sliding sleeve through a pin shaft.

[0013] Furthermore, one end of the second connecting frame and one end of the other diagonal support frame are both rotatably connected to the wall connecting frame, wherein a plurality of fixing bolts on one side of the two embedded plates respectively pass through the wall connecting frame and are fixed to the wall connecting frame.

[0014] Furthermore, the lifting mechanism includes a first lifting assembly for lifting one end of the sliding sleeve and a second lifting assembly for lifting one end of a group of diagonal support frames. The first lifting assembly includes two first lifting rings and two adjustment frames. The two first lifting rings are respectively fixedly connected to the upper surfaces of the two sliding sleeves. A support plate is fixedly connected between the two adjustment frames. A second winch is fixedly connected to the upper surface of the support plate. The two adjustment frames are fixed to one of the groups of mounting holes by bolts.
