Detailed description of the invention
For the benefit of the understanding to the structure of the present invention, illustrates below in conjunction with drawings and Examples.
With reference to Fig. 1, for the schematic flow sheet of large-span steel girder construction method of installation of the present invention, as it is shown in figure 1, the invention provides a kind of large-span steel girder construction method of installation, mainly include the following step sequentially performed:
Step S1, encloses one support jig 3 of interim installation in scope at shear wall 1；
Step S2, utilizes support jig 3, is installed on shear wall by the first conversion beam 2；
Step S3, utilizes support jig 3 and the first conversion beam 2, by the first main couple 4 interconnection on the first conversion beam 2；
Step S4, utilizes the first main couple 4, installs and the first conversion beam 2 many conversion beams 2 ' side by side under the first main couple；
Step S5, utilizes the first conversion beam 2 and many conversion beams 2 ', and on the first conversion beam and many conversion beams, many main couples 4 ' are installed in segmentation.
Hereinafter each step above-mentioned is described in detail:
With reference to Fig. 2, for performing the structural representation of step S1 and step S2 in Fig. 1, as shown in Figure 2, first, the shear wall 1 that four sides set by the construction field (site) is thirty years of age, center in shear wall 1 scope, the interim support jig 3 installing one vertical high 52m of erection, then, utilize this support jig 3, the midpoint of the first conversion beam 2 is installed on the top of support jig 3 so that the first conversion beam 2 level is across shear wall 1, and the two ends of the first conversion beam 2 are respectively arranged in the centre position of two shear walls 1 of opposition.
With reference to Fig. 3, for performing the structural representation of step S3 in Fig. 1, as shown in Figure 3, coordinate and utilize an above-mentioned support jig 3 and the first conversion beam 2, horizontal fragmentation installs the first main couple 4: specifically, first main couple 4 can the form of sectionally smooth join be installed, wherein, the point midway that need to midpoint (i.e. the midpoint of the whole first main couple 4) intersection that be in this middle linkage section of the first main couple 4 is installed on the first conversion beam 2, and, the two ends of the first main couple 4 are connected and fixed on two shear walls 1 of opposition, the first main couple 4 and the first conversion beam 2 after installation are mutually perpendicular to.
With reference to Fig. 4, for performing the structural representation of step S4 in Fig. 1, as shown in Figure 4, utilize step S3 to be completed the first main couple 4 installed, in the both sides of the first conversion beam 2, many conversion beams 2 ' are respectively perpendicular and are mounted side by side in the first main couple 4 times, and, being evenly arranged the distance between many conversion beams 2 ', the two ends of every conversion beam 2 ' are all connected fixing with shear wall 1, to realize the alternating expansion of many conversion beams 2 '.
With reference to Fig. 5, for performing the structural representation of step S5 in Fig. 1, as shown in Figure 5, step S4 is utilized to be completed many conversion beams 2 ' and the first conversion beam 2 installed, both sides at the first main couple 4, many main couples 4 ' are respectively perpendicular and are mounted side by side on many conversion beams 2 ' and the first conversion beam 2, and, it is evenly arranged the distance between many main couples 4 ', every main couple 4 ' segmentation connects and is across shear wall 1, the two ends of every main couple 4 ' are all connected fixing with shear wall 1, realize the alternating expansion of many main couples 4 ' with this.Finally, existing installation method can be passed through, install between many parallel main couples 4 ' and connect many root systems bar, between main couple 4 ' and the shear wall 1 of most sidepiece, be also connected to many root systems bar.
With this, complete this steel girder erection.After completing installation, support jig 3 can be removed.
