Description
Technical Field
The utility model relates to the field of building equipment, in particular to an adjusting mechanism for a tower crane wall-attached supporting platform.
Background
In the existing super high-rise (buildings with building heights exceeding 100m or floors reaching 40 floors and above), in order to ensure stability and reliability after the building is completed, the building is constructed by adopting a frame-core tube type structure in the prior art.
For the frame-core tube building structure (shown in figure 6 of the specification attached drawings), the frame-core tube building structure has the advantages of high structural strength, high space utilization rate, good flexibility, good earthquake resistance, high construction efficiency and the like. The main components of the building frame structure comprise a frame structure which is built on the periphery of the building and a core tube which is built in the middle of the building, wherein the frame structure on the periphery is generally built by adopting reinforced concrete or steel structures, and the structure consists of horizontal and vertical beams, columns, frames and other components and can bear the gravity and wind load of the building; the core tube is usually cast by reinforced concrete, has higher compression resistance and shear resistance, and mainly aims to provide the longitudinal stability of the building, bear treatment load and resist lateral force. Therefore, the building structure is widely applied to modern building construction.
But at the same time, for super high-rise (buildings with building heights exceeding 100m or floors reaching 40 layers and above), as the building heights of people are continuously refreshed (the existing buildings can reach 600 m), the building can not realize the stability of the building by only relying on the building materials and the framework-core tube structure. Architects will therefore modify the appearance of buildings, for example, to image the building design into a "discone" like "pyramid" shape or other shape. When the external shape of some buildings is in a pyramid shape, the inner core tube of the building is also designed into a pointed tower shape (as shown in figure 7 of the specification), and gradually contracts inwards from bottom to top, so that a pattern with wide bottom and narrow top is formed, and the overall stability of the building is further ensured.
In the construction of the existing building, the tower crane is an absolutely necessary building device, and the tower crane is required to be known to climb upwards gradually along with the rise of the building when in use. In the construction of super high-rise (buildings with building heights exceeding 100m or floors reaching 40 floors and more), the climbing mode of the tower crane is also divided into various types, and among them, a mode of adding standard knots (the standard knots are members forming the bottom support of the tower crane), a mode of constructing a wall-attached support platform on the outer wall of the middle core tube (wall-attached climbing mode), and a mode of constructing a building machine at the top end of the building. In the modes, the second type wall-attached climbing mode (shown in figure 6 of the specification) is the mode with the highest cost performance in the aspects of economy and construction convenience compared with the other two types, so that most of super high-rise buildings adopt the second type wall-attached climbing mode to realize the climbing of the tower crane.
When the middle wall-attached climbing tower crane ascends, a plurality of groups of wall-attached supporting platforms are built on the outer wall body of the core tube (as shown in figure 6 of the specification), meanwhile, a jacking mechanism is arranged at the bottom of the tower crane to match with the wall-attached supporting platforms for climbing, and the plurality of groups of wall-attached supporting platforms for climbing are required to meet one requirement, namely, the plurality of groups of wall-attached supporting platforms are mutually opposite to each other (as shown in figure 6 of the specification). This must be faced with a great problem when facing buildings in which the internal core of the aforesaid building is designed as a "pointed tower". When one of the groups of wall-attached support platforms is located above the core tube wide-narrow turning position, and the other group of wall-attached support platforms is located below the core tube wide-narrow turning position, the outer wall bodies of the core tubes are not flush, so that the requirements of the groups of wall-attached support platforms cannot be met, a dislocation phenomenon (shown in figure 5 of the specification) occurs between the groups of wall-attached support platforms, and the wall-attached support platforms cannot be further matched with an auxiliary tower crane to continue climbing.
Aiming at the problems, the traditional solution is to completely remove the tower crane positioned on the wall-attached supporting platform, then pass through the non-flush place of the outer wall of the core tube, reassemble the tower crane, and further make the tower crane work again. In actual work, the method needs 9 days for reassembling the tower crane, if the disassembly time of the tower crane is added, the whole method needs more than ten days, the work is carried out in high altitude, workers are required to debug and align in person in the disassembly and assembly process, and the work is dangerous.
Therefore, aiming at the defects of the traditional technology, a new method is designed to realize convenient climbing of the wall-attached climbing tower crane at the inward shrinkage transition position of the core tube, and the method is that a plurality of groups of wall-attached supporting platforms can be kept in a flush state all the time by adjusting the wall-attached supporting platforms, so that the tower crane can climb smoothly beyond the wide and narrow turning positions of the core tube without disassembling and installing the tower crane.
Disclosure of Invention
The utility model aims to provide an adjusting mechanism for a tower crane wall-attached supporting platform, which is different from the traditional mode, when the construction of the tower crane ascends to a place where the upper wall body and the lower wall body of a core tube of a building are not flush, the wall-attached supporting platform for supporting the tower crane is adjusted to cope with the situation that the outer wall bodies of a plurality of groups of wall-attached supporting platforms cannot be aligned because the outer wall bodies of the core tube are not flush, so that the traditional mode is not needed, the tower crane is removed, and then the requirement of climbing the tower crane in the place where the upper wall bodies and the lower wall bodies of the core tube are not flush is met, and the wall-attached climbing type tower crane can be enabled to be corresponding to various complex building shapes.
