Embodiment 1
[0031] The present embodiment provides a high-altitude large-span cantilever structure construction platform, including: a concrete structure, a column embedded in the concrete structure, a parallel chord truss arranged on the column, an upper chord secondary beam arranged on the upper chord of the truss, a The lower chord secondary beam of the lower chord of the truss, the pressing plate or supporting formwork set on the upper chord secondary beam.
[0032] The present embodiment also provides a construction method for the above-mentioned high-altitude large-span cantilever structure construction platform, comprising the following steps:
[0033] 1) The concrete base module is constructed first, and after the concrete base module reaches the design strength, the column is installed on the concrete base module;
[0034] 2) After the installation of the column is completed, construct the concrete base module on the concrete base module, and part of the column is pre-buried in t...
Embodiment 2
[0041] like figure 1 , 2 As shown, the present embodiment provides a construction platform of a high-altitude large-span cantilever structure 1, comprising: a concrete structure 2, a column 3 embedded in the concrete structure 2, a parallel chord truss 4 arranged on the column 3, a truss arranged on the truss 4. The upper chord sub-beam 51 of the upper chord 42, the lower chord sub-beam 52 arranged on the lower chord 41 of the truss 4, the pressing plate 9 or the supporting template arranged on the upper chord sub-beam 51. The construction platform is arranged below the high-altitude large-span cantilever structure 1 .
[0042] Specifically, the column 3 in this embodiment is a wide flange H-shaped steel column. The parallel chord truss 4 includes a lower chord 41 , an upper chord 42 and a web 43 . The upper chord 42 and the lower chord 41 are parallel to each other, and the upper chord 42 is connected to the lower chord 41 through the web 43 . Specifically, in this embodim...
