Novel trestle used between offshore oil platforms
The invention relates to a novel trestle used between offshore oil platforms. The novel trestle is characterized by comprising a trestle body, two or more supporting frames and two or more steel cables. All the supporting frames are connected to the bottom end of the trestle body in a fastened mode at intervals, each steel cable is connected with the bottom ends of all the supporting frames in a fastened mode, and the two ends of each steel cable are connected to the two ends of the trestle body in a fastened mode. The trestle body is formed by connecting a plurality of horizontal transverse beams, horizontal longitudinal beams and first oblique beams in a fastened mode. Each supporting frame comprises a transverse connecting beam connected with all the steel cables in a fastened mode. One ends of two vertical beams and one ends of a plurality of second oblique beams are symmetrically connected to each transverse connecting beam in a fastened mode, and the other ends of all the vertical beams and the other ends of all the second oblique beams are connected with the trestle body in a fastened mode. A third oblique beam is connected to the diagonal position of every two vertical beams in a fastened mode. The cross section height of the trestle body is gradually increased from the two ends to the middle, and the cross section of the trestle body is of a triangular structure.
