Description

Tower crane wall-attached supporting platform equipment and application method thereof

Technical Field

The invention relates to the field of buildings, in particular to tower crane wall-attached supporting platform equipment and a using method thereof.

Background

In the case of building super high-rise buildings (buildings with building heights exceeding 100m or floors reaching 40 floors and more), in order to ensure stability of the building in high altitudes, construction is performed using a frame-core tube structure. The frame-core tube structure is formed by constructing a core tube formed by pouring reinforced concrete at the central position of a building, and simultaneously constructing an external steel structure frame at the peripheral position outside the core tube, as shown in figure 6 of the accompanying drawings. The core tube is used for setting elevator shafts, stairs, ventilation shafts, cable shafts, public toilets and part of setting rooms in the whole building, and the outer frame is used for office entertainment. The reason for this design is that the core tube located in the central position of the building is used for bearing the horizontal acting force applied to the whole building, the external frame bears the horizontal acting force and the vertical loading force applied to the building, so that the forces applied to the building can be well dispersed, the stability of the building is maintained, and the external frame is made of steel structures, so that the building using area is larger. Meanwhile, the frame-core tube structure is already applied in the middle of the 19 th century, and the current super high-rise building is built by adopting the frame-core tube structure along with the continuous maturity of the technology.

The tower crane is an indispensable construction equipment in the construction of a building. The tower crane comprises a standard knot, a tower crane rotary seat, a balance arm, a winch, a balancing weight, a suspension arm and the like as shown in figures 11-14 of the attached drawings. Meanwhile, when building a super high-rise building (building with building height exceeding 100m or building with storeys reaching 40 layers or more), the tower crane can rise along with rising of the building, and in order to reduce investment of building cost of the tower crane and facilitate building of the building, a plurality of groups of wall-attached support platforms are arranged on the side wall of a building core tube as shown in an attached drawing 7 of the specification, the tower crane is arranged on the platform, climbing devices are arranged on the tower crane, the tower crane can ascend upwards through the climbing devices by means of the plurality of groups of wall-attached support platforms (a flow chart of using the tower crane climbing devices is shown in an attached drawing 8 of the specification), meanwhile, when the tower crane passes through the climbing devices, the wall-attached support platforms at the upper end are detached and then are arranged on the upper side of the upper end wall-attached support platform, and the tower crane can be recycled. The tower crane can be lifted upwards all the time in this way, which is different from the mode of adding standard knots or other modes, the cost can be saved, meanwhile, as shown in figure 7 of the specification, the whole tower crane is attached to the core tube and is in a 'suspended state', the tower crane base does not occupy the building construction place at the lower end of the tower crane, the construction of a building is convenient, and therefore, the climbing mode of the tower crane attached to the wall is widely applied in the building of an ultra-high layer (building with the building height of more than or equal to 100 m).

For the mode that the middle tower crane climbs by using the attached walls, certain requirements are met for the installation positions among the groups of attached wall support platforms, and in the specification, as shown in figure 7 of the accompanying drawings, four directions of the upper end and the lower end, which are aligned in the front-back, left-right direction, can be seen, so that the climbing requirement of the tower crane can be met.

However, in some super high-rise buildings (buildings with building heights exceeding 100m or floors reaching 40 floors or more), the height of the building is generally more than 200m in order to save land and increase more building use area. In order to ensure the stability of a building with such a height, the design of the building is improved on the basis of the construction of the frame-core tube structure, for example, the core tube is arranged in a shape gradually shrinking from bottom to top as shown in fig. 9 of the specification, so that the stability and the reliability of the building are ensured. However, when the tower crane uses the mode of climbing the middle wall-attached support platform, a phenomenon of dislocation between the upper end and the lower end wall-attached support platforms as shown in the figure 10 of the description exists among a plurality of groups of wall-attached support platforms on the peripheral wall of the core tube. When this situation is met, the wall-attached support platform is not used for helping the tower crane to climb upwards continuously. In order to enable the tower crane to continue to ascend, the tower crane attached to two sides of the peripheral wall of the core tube can only be removed by using the tower crane in the middle position in the figure 10 of the specification, and then the tower crane is installed on the first wall-attached supporting platform in the upper end in the figure 10 of the specification. The installation of the tower crane can be completed by 11 steps as shown in fig. 11-14 of the attached drawings, manual debugging and comparison and butt joint are needed in each installation step, and as the building height rises, the installation of the tower crane can be filled with more dangers, the installation difficulty is greatly increased, and when the tower crane is installed at a position 200m above, the installation operation can be filled with more uncertain factors, such as environmental factors, the hidden danger of the tower crane installation process is increased, meanwhile, the installation of the tower crane can be completed only in 9 days, the installation of the tower crane can be completed only in a good state, and the site construction of a building can be stopped in the process of the disassembly and installation of the tower crane, so that the disassembly and the installation of the tower crane are greatly limited.

Therefore, a wall-attached support system convenient for climbing a tower crane needs to be studied, when the upper and lower peripheral widths of a core tube are different as shown in an attached drawing 10 of the specification, climbing of the tower crane can be unaffected, the requirement that the tower crane continuously climbs upwards can be met without detaching the tower crane in an installation mode, the risk of high-altitude installation of the tower crane is directly avoided, the construction flow is reduced, the construction progress is accelerated, potential safety hazards are effectively avoided, and the construction cost is saved.

When facing the core tube in the mode of 'upper narrow lower wide' in the figure 9 of the specification attached to the wall, when the traditional tower crane attached to the wall is constructed to the 'wide and narrow turning position' of the core tube, the phenomenon of 'dislocation' between the upper part of the attached wall supporting platform positioned at the upper end of the 'wide and narrow turning position' and the lower part of the attached wall supporting platform positioned at the lower end of the 'wide and narrow turning position' appears, and at the moment, the attached wall supporting platform cannot continue to assist the tower crane to climb.

In the disassembly and installation process of more than ten days, in order to prevent dangerous accidents, construction of a building is suspended, if a building design with a plurality of wide and narrow turning positions is faced, the traditional operation flow greatly prolongs the construction period, workers are required to carry out auxiliary adjustment and installation in the disassembly and installation process, and the building is also full of potential safety hazards and dangerous when working in an environment of 100-200 m at high altitude.

Aiming at the traditional climbing method of the wall-attached tower crane, the method adopted by the invention can be more convenient and quicker, the step of installing the tower crane again can be directly saved by using the method disclosed by the invention, so that the defect of the traditional mode in the prior art can be directly avoided, the operation step of S2 can be completed only by 30 minutes (the time is also different according to the extending length of the telescopic slide rod, the time is also different), the climbing time of the operation step of S3 is always 1 hour compared with the traditional climbing time, the wall-attached support platform can be arranged in advance before the climbing of the operation step of S4, the operation step of S5 can be directly carried out after the climbing to a proper height, the time of the operation step of S5 is always the time of S3, the operation step of S6 is completed by 3-4 hours in order to ensure that the operation step of S6 is safe and stable, the climbing time of the whole (including the general lifting time) is always 4 days, and the mounting and dismantling of workers are also greatly shortened by comparing the time with the time of the prior art. And when facing some special shaped buildings in the prior art, for example: the shape of the invention is opposite to the shape of figure 9 of the specification, and the shape of the invention is 'wave shape' and 'pyramid shape', etc. the invention can be applied to the climbing tower crane with wall for climbing.

The reason why the tower crane approaches the wall of the core tube of the building is described with particular emphasis, and since the existing device and the design supporting mode of the device are to install an extending platform on the wall of the core tube and simultaneously support the tower crane by adopting a triangular structure, it is required to understand that the farther the tower crane is from the wall of the core tube, the larger the acting force born by the jacking platform 3.
