Embodiment Construction

[0042] The accompanying drawings are schematic diagrams of the implementation of the present invention, so as to facilitate the understanding of the operation principle of the structure. The specific product structure and proportions can be determined according to the use environment and conventional techniques.

[0043] like figure 1 , 2 As shown, it includes a simply supported plate, a bottom beam, a polyurea cushion, a frame column, a lever, a rotating shaft B, a universal joint, and a telescopic rod, such as figure 2 , 10 As shown in the figure, the frame columns at the joint of the vertical wharf and the sloping wharf are all poured with concrete bottom beams, and the top of the bottom beam has a groove with an inverted trapezoid cross-section; as in figure 1 , 10 As shown, the height of the slope C on the side of the groove close to the floor is greater than the height of the slope D on the side away from the floor; such as figure 2 , 3 As shown in , 11, there ar...

Abstract

The invention belongs to the field of frame wharfs, and particularly relates to a flexible connecting structure of an overhead vertical frame wharf and an overhead ramp wharf, which comprises a simple support plate, a bottom beam, a polyurea cushion layer, frame columns, a deflector rod, a rotating shaft B, a universal joint and a telescopic rod, a groove with an inverted trapezoidal cross section is formed in the top of the bottom beam; when a moderate earthquake or an intensity earthquake occurs, relatively large relative displacement is generated between the overhead vertical frame wharf and the overhead slope ramp wharf, and the simple support plate moves upwards along the inclined plane C or the inclined plane D of the bottom beam groove under the action of tension or pressure at the two ends; rigid connection between the overhead vertical type frame wharf and the overhead slope ramp wharf is automatically relieved, structural safety is guaranteed, and the purposes that in the three-level targets of earthquake fortification, middle earthquakes can be repaired, and large earthquakes do not fall down are achieved.

Description

technical field [0001] The invention belongs to the field of frame wharfs, and in particular relates to a ductile connection structure of an overhead vertical frame wharf and an overhead ramp wharf. Background technique [0002] As an important transportation infrastructure, port terminals usually need to undertake major transportation tasks after an earthquake, and play a lifeline role in ensuring the safety of people's lives and properties in the disaster area. Therefore, the seismic design of the wharf is highly valued. [0003] Overhead vertical frame wharf is a common structural form of inland wharf. It is suitable for inland river deep overburden foundation and is widely used in the construction of inland river ports, especially in the construction of reservoir area ports. [0004] For ports in the reservoir area, since the water level varies greatly with the seasons, it is often necessary to set up an overhead ramp wharf next to the overhead vertical frame wharf to fo...
