A tower crane dismantling structure and method for high-rise installation

Abstract

The invention discloses a tower crane dismantling structure and method for high-rise installation. By adopting a cantilever steel beam structure on the outside of any floor of the high-rise building to fix the tower crane and the roof crane, the installation structure is novel and overcomes the problem of "herringbone"-shaped high-rise buildings. There is no way to install the tower crane at the top and the defects of the roof hanging structure, choose to install the fixed tower crane and roof crane by installing cantilever steel beams from the floor where construction operations are required. , novel, and can be installed on the outside of any floor, with strong installation flexibility, especially for the repair of the main structure and the installation of external equipment, there is no need to install tower cranes and roof cranes from the ground, which greatly saves tower cranes and roofs. Installation costs and operating costs of the crane.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to a disassembly method of a tower crane installed on an intermediate floor. Background technique [0002] Tower cranes are the most commonly used lifting equipment on construction sites, also known as "tower cranes", which are extended section by section (height) (referred to as "standard section") to lift steel bars and wood panels used in construction. , Concrete, steel pipe and other construction materials. Tower crane is an essential equipment on the construction site. [0003] In existing buildings, in order to save floor space on the ground and make better use of space, buildings are usually built very high, and for the sake of beauty, glass is installed on the outer walls. The usual method of installing glass is Installation indoors and outdoors, and for the installation of glass on the roof, especially the roof of the "human" structure, the installation is generall...

Problems solved by technology

[0003] In the existing buildings, in order to save the ground area and make better use of the space, the building is usually built very high, and for the sake of beauty, the outer wall will be installed with glass. Usually, the method of installing glass is It is installed indoors and outdoors. For the installation of glass on the roof, especially the roof of the "herringbone" structure, it is generally installed by tower crane. This method must be synchronized with the construction of the main body of the building, and the tower crane is generally used. Installed on the foundation cap of the ground, fixed by pre-embedded anchor screws, and then added standard sections and attachment devices to the original standard height, due to the large size and heavy weight, if it is installed from the ground to the top of a super high-rise, many standard sections need to be installed And attachment frame, if a small-scale construction project is carried out, installing a tower crane from the ground will waste a lot of manpower, material and financial resources, time-consuming and labor-intensive, and for some structures that have already built the main body of the building, and the roof cannot be installed with tower cranes and roof cranes, If you want to carry out high-rise construction, you need to build the foundation of the tower crane from the ground, which is extremely inconvenient. When you need to dismantle the tower crane, you may need to use another high-rise building to build a roof crane, which is extremely inconvenient
