Detailed Description
The utility model is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
Referring to fig. 1 and 2, the present utility model provides a lifting device for a large span steel structure roof, comprising: composite column 1, support 2, supporting beam 3, lifting jack.
The number of the composite columns 1 is two. The two composite columns are oppositely arranged.
Specifically, the composite column 1 includes a central steel pipe column 11 and four satellite uprights 12. Four satellite uprights 12 are arranged at equal intervals along the circumferential direction of the central steel pipe column 11. Four satellite pole setting are arranged outside the central steel-pipe column in matrix. A plurality of connecting beams 13 are connected between two adjacent satellite uprights 12. A plurality of spoke beams 14 are connected between each satellite upright 12 and the central steel pipe column 11.
The support 2 is mounted on the top end of the composite column 1. Support beam 3 support beams 3 are mounted at both ends to the supports 2 on the two composite columns 1. The lifting jack is mounted to the support beam 3.
As a preferred embodiment, the diameter of the central steel pipe column 11 is larger than the diameter of the satellite pole 12.
In this embodiment, the diameter of the central steel pipe column 11 is much larger than the diameter of the satellite pole 12.
With continued reference to fig. 1, diagonal braces 16 are connected between adjacent ones of the satellite poles 12. The end of the diagonal brace 16 is connected to the junction of the satellite upright 12 and the tie 13.
Specifically, the upper end of the diagonal member 16 is connected to the junction between the satellite upright 12 and the upper tie 13. The lower end of the diagonal brace 16 is connected to the junction of the satellite pole 12 and the underlying tie 13.
