Description

Technical Field

[0001] The invention belongs to the technical field of Bailey sheets, and in particular relates to a high-strength Bailey sheet capable of resisting buffering and a use method thereof. Background Art

[0002] Bailey plates, also known as Bailey frames, Bailey beams or trusses, can be used for highway bridges, assembling gantry cranes, guide beams, bridge erecting machines, hanging baskets, etc. The gantry is assembled using prefabricated highway steel bridge components, and its span and column height are adjustable to adapt to different work sites. It is widely used in highway, railway, municipal, building, water conservancy and other construction projects, bridge construction prefabrication sites to lift and move prefabricated components, transport and install beams next to bridge piers and other on-site construction operations. Bailey plates have the characteristics of simple structure, convenient transportation, quick erection, large load capacity, good interchangeability and strong adaptability.

[0003] The existing Bailey plates can be used to build temporary bridges. During the use of temporary bridges, since the Bailey plates bear the main load gravity, the load-bearing performance of the Bailey plates is crucial. The existing Bailey plates are welded fixed frame structures. When the Bailey plates are subjected to load gravity, they cannot buffer the load gravity, resulting in poor anti-buffering performance of the Bailey plates, thereby affecting the structural strength of the Bailey plates during use.

[0025] B: Then the first adjustment rod on the first buffer vertical rod will be pressed toward the first fixed rod. At this time, the first adjustment rod presses the first rubber buffer seat through the first sleeve rod to reduce the force acting on the first buffer vertical rod;
