Description
Technical Field
The invention relates to the technical field of hoisting machinery, in particular to a climbing method of an internal climbing tower crane in a narrow space.
Background
The inner climbing tower crane is a tower crane which is arranged in a core tube structure such as an elevator shaft or a staircase in a building, can climb upwards gradually along with the construction progress, and has incomparable superiority and practical value. The tower crane is constructed in the building, does not occupy the construction site, is suitable for on-site narrow projects, and is particularly beneficial to urban area reconstruction and extension projects; tracks do not need to be laid, a reinforced concrete foundation does not need to be specially manufactured, construction preparation is simple (only holes need to be reserved, strength is locally improved), and cost is saved; a plurality of anchoring devices and complex attachment operation are not needed; the working range is large. The internal climbing tower crane is arranged in the middle of a building to cover the building, so that the range of extending out of the building is small, and surrounding obstacles, sidewalks and the like are effectively avoided; because the crane boom can be shorter, the hoisting performance can be fully exerted; the construction requirement can be met only by a small number of standard sections and a common tower body of 30 meters (wind load is small), one-time investment is low, the height of the building is higher, and the economic benefit is more obvious.
As shown in fig. 1, when climbing operation is performed on the current internal climbing tower crane, the tower crane body 1 is usually fixed by three sets of internal climbing frames 1a, 2a, 3a and climbing steel beams 1b, 2b, 3b arranged at intervals on the tower crane body 1, after the climbing operation is completed, the tower crane body 1 is fixed by the upper two sets of internal climbing frames 2a, 3a and climbing steel beams 2b, 3b, after the bottommost set of internal climbing frames 1a and climbing steel beams 1b are removed, the internal climbing frames and climbing steel beams need to be transported to the outdoor for stacking, and are installed and used as the uppermost internal climbing frames and climbing steel beams of the tower crane during the next climbing operation.
But because the interior tower machine that climbs generally sets up inside building core section of thick bamboo structure, because building core section of thick bamboo construction adopts climbing formwork, jack-up die class die carrier system from lift-type usually, the position that this type of die carrier system upper portion platform was reserved for interior tower machine that climbs is very narrow and small usually. Interior frame and the girder steel that climbs are in recycling use, need tear earlier the interior frame that climbs and tear the girder steel that climbs again open when demolising, must adorn earlier again in the installation and climb the girder steel reloading and climb the frame in, this just causes the interior frame that climbs and need look for the place earlier after tearing down and deposit, the interior frame that climbs that is inside a core section of thick bamboo and the girder steel that climbs can't be transported to outdoor from a core section of thick bamboo top, and in the time of super high-rise core section of thick bamboo construction, no horizontal structure in the core section of thick bamboo, consequently, need to transport to the barrel outside from the barrel inside, this process is very consuming time, generally need the manual work to climb the frame and climb the girder steel from the core section of thick bamboo side in taking out, thereby realize the interior frame and the transportation of the girder steel that climbs, this operation process.
