Embodiment Construction
[0020] A method for installing large-span variable-section bolted spherical joint reticulated shells, such as Figure 7 The construction site shown is divided into four areas, from left to right are ① area, ② area, ③ area, ④ area, ① area and ② area are rectangular, ③ area and ④ area are trapezoidal, partitioned installation, that is Take one internode at one end of each area (①Area takes the right end, ②Area takes the left end, ③Area, ④Area takes the right end), and install the grid in the internode after forming a reference unit by block installation.
[0021] Taking area ② as an example, the steps are to first install the unit grid 12 as the reference unit, and the installation method of the unit grid 12 is as follows: figure 1 As shown, first assemble the middle arc unit I on the ground, and then lift it up with the crane group I1; figure 2 As shown, the middle arc unit II is assembled on the ground and hoisted with the crane group II2, such as image 3 As shown, the mi...

The invention relates to a building construction method, in particular to an installing method of a large-span variable-cross-section screw bolt ball node reticulated shell. In order to solve the installing problem of a large-span variable-cross-section screw bolt ball reticulated frame in the large-scale industrial region, the installing method of the large-span variable-cross-section screw bolt ball node reticulated shell is provided. The installing method comprises the following steps that firstly, unit reticulated frames are installed to be used as reference units, then, the reference units are used as the reference for constructing a platform, a crane is utilized for matching the artificial high-altitude individual installation to realize gradual spanning lateral pushing until the reticulated frames of the region are installed in place, and the reference units of the other three regions are constructed according to the method until the installation of all of the reticulated frames is completed. The scheme adopted by the method provided by the invention has the characteristics that the traditional single high-altitude individual installation or blocked or stripped construction methods are changed, the advantages of the two construction methods are sufficiently utilized and are organically combined, in addition, the simulation stress analysis in the construction period is carried out in advance, the construction safety of the large-span variable-cross-section screw bolt ball node reticulated frames is ensured, the construction efficiency is improved, and the example is provided for the similar project construction in future.
Description
technical field [0001] The invention relates to a building construction method, in particular to a method for installing a large-span variable-section bolt ball joint reticulated shell. Background technique [0002] At present, with the increasing application of large venues and long-span coal storage structures, the bolted ball grid has been widely used due to its flexible structure, low steel content, fast construction speed, and applicable to long-span structures. For example, in some special occasions, such as a company's production area, the construction area is 31648.00㎡. The roof adopts a carbon steel grid frame with square pyramidal bolt ball joints. The projected dimension axis of the building is 40-88 meters x 418 meters. The grid support form is the upper chord column point support. The thickness of the grid frame is 4000㎜; the arch height of the grid frame is 26624㎜~37572㎜; the axis expansion area is 41073㎡; the grid size is 4000㎜×4000㎜. The rod material is Q23...
