Embodiment
[0028] Embodiment: As shown in the figure, a comprehensive construction method of a large cantilever ring steel structure ring corridor includes the following steps:
[0029] The first step: the installation of the vertical web member 1 of the steel structure and the establishment of the temporary support frame 16 are carried out. The vertical web member 1 of the steel structure is a steel concrete column. When the lower chord 2 of the hoop truss and the upper chord 9 of the hoop truss are installed, they need to be supported below by a temporary support frame 16 forming a three-point support system.
[0030] Step 2: Install the lower chord 2 of the ring truss.
[0031] Step 3: Install the vertical web bar 3, the horizontal diagonal web bar 4, the horizontal radial web bar 5, the middle diagonal web bar 6 of the inner and outer rings, the middle diagonal web bar 7 of the inner ring and the middle diagonal web bar 8 of the outer ring.
[0032] 3 vertical webs, 4 horizontal di...

The invention relates to a comprehensive construction method for a large-cantilever annular steel structure ring corridor, and belongs to the technical field of steel structure construction. The comprehensive construction method comprises the following operation steps: 1, mounting vertical web members of a steel structure and setting a temporary support frame; 2, mounting a lower chord of an annular truss; 3, mounting the vertical web members, horizontal diagonal web members, horizontal radial web members, inner and outer ring middle diagonal web members, inner ring middle diagonal web members and outer ring middle diagonal web members; 4, mounting an upper chord of the annular truss; 5, mounting a lower side cantilever steel beam and an upper side cantilever steel beam; 6, mounting a lower side ring beam and an upper side ring beam; 7, mounting a lower side face inner face inner support and an upper side face inner support; and 8, removing the temporary supporting frame located below the lower chord of the annular truss, and completing mounting of the whole steel structure annular corridor. The comprehensive construction method has the advantages of high construction efficiency, low mounting cost and high safety, the mounting convenience is improved, the construction period is shortened, and meanwhile the potential safety hazards of construction are reduced.
Description
technical field [0001] The invention relates to the technical field of steel structure construction, in particular to a comprehensive construction method for a ring corridor of a large cantilever ring steel structure. Background technique [0002] With the country vigorously promoting the direction of fabricated steel structures, the construction of large complex steel structures is in full swing. At the same time, with the rapid development of the domestic economy and the improvement of people's living standards, the functional requirements of public buildings have been upgraded from meeting basic functional requirements to the development of architectural art with large space and streamlined aesthetic feeling. In the face of buildings with more complex structures and more difficult construction, it has become an indispensable link to seek more efficient, safe and economical construction methods. [0003] The large cantilever steel structure ring corridor is a special shap...
