Embodiment Construction
[0020] Example Figure 2 to Figure 5 As shown, the climbing method of the inner tower climbing machine in the narrow space of the present invention comprises the following steps:
[0021] Step 1, such as figure 2 As shown, three sets of inner climbing frames and four sets of climbing steel beams are placed inside the building core tube structure, the first inner climbing frame 1a and climbing steel beams 1b are arranged at the bottom A of the tower crane body 1, the second inner climbing frame 2a and The climbing steel beam 2b is arranged in the middle part B of the tower crane body 1, and the third inner climbing frame 3a and the climbing steel beam 3b are arranged in the upper part C of the tower crane body 1;
[0022] Step two, such as image 3 As shown, when the internal climbing tower crane runs normally until it needs to climb, the tower crane body 1 performs internal climbing operations, the bottom of the tower crane body 1 climbs to the position of the second inner ...

The invention discloses a climbing method of an inner climbing tower crane in a narrow space. According to the climbing method, three sets of inner climbing frames and four sets of climbing steel beams are placed inside of a building core tube structure, and the first to third inner climbing frames and the climbing steel beams are arranged at the bottom, the middle and the upper portion of a towercrane body; the bottom of the tower crane body climbs to the positions of the second inner climbing frame and the climbing steel beams, and the third inner climbing frame and the climbing steel beamsare located in the middle position of the tower crane body; the fourth climbing steel beam is arranged on the upper part of the tower crane body, the first inner climbing frame is removed and transported directly from the interior of the building core tube structure to the fourth climbing steel beam and installed; during the subsequent climbing of the inner climbing tower crane, the first climbing steel beam and the second inner climbing frame are removed to the upper part of the tower crane body to be installed, and the above steps are executed in sequence to complete the climbing operationof the tower crane body at all climbing trips. According to the method, the inner climbing frames and the climbing steel beams are directly transported inside the building, the interference from an upper formwork system is less, the overall climbing time and the cost of the tower crane are saved, and potential safety hazards are avoided.
Description
technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a climbing method for an internal climbing tower crane in a narrow space. Background technique [0002] The internal climbing tower crane is a tower crane installed in the core tube structure such as the elevator shaft or stairwell inside the building. It can gradually climb upwards with the construction process. It has incomparable advantages and practical value. The tower crane works inside the building and does not occupy the construction site. It is suitable for narrow projects on site, especially for urban reconstruction and expansion projects; there is no need to lay tracks, no need to make special reinforced concrete foundations, and the construction preparation is simple (only need to reserve openings, local Improve the strength), save costs; no need for multi-channel anchoring devices and complicated attachment operations; large operating range. The internal ...
