How To Improve The Strength And Rigidity Of Bailey Panel

In the case of bailey panel , the strength is increased by 33% and the stiffness is increased by 2.3 times. The scope of application is 4.2M for single-lane bridge deck, 9.14-76.2M for combined span, 7.4M for two-lane bridge deck, and 9.14-57.91M for combined span. The application of Bailey panel can be used for road bridges, assembling gantry cranes, guide beams, bridge erecting machines, hanging baskets, etc. Bailey truss combination gantry cranes use fabricated highway steel bridge components to assemble gantry, and its span and column height Adjustable to adapt to different work sites, it is widely used in construction projects such as highways, railways, municipal administration, construction, water conservancy, etc., bridge construction prefabrication yard hoisting and transporting prefabricated components, and bridge piers transporting and installing beams and other on-site construction operations. The structural beret is welded by upper and lower chords, vertical rods and diagonal rods. The ends of the upper and lower chords are provided with male and female joints, and the joints are provided with a pestle holder connecting pin hole. The chord of the beret is composed of two No. 10 channel steels (back-to-back). On the lower chord, a number of steel plates with round holes are welded. There are supply and reinforcement chords and double-layer trusses in the upper and lower chords. For the connecting bolt holes, there are four bolt holes for connecting the support frame in the upper chord, and the two holes in the middle are for connecting double or multi-row trusses with the same node.

The two holes at both ends of the Bailey sheet are used to connect across the internodes. When multiple rows of berets are used as beams or columns, the joints of the upper and lower berets must be reinforced with a support frame. On the lower chord, there are 4 cross-beam pads with tenons above them to fix the position of the cross-beam on the plane. There are also two elliptical holes on the channel steel web at the end of the lower chord for connection Use of wind-resistant rods. The vertical rods of the beret are all made of 8# I-steel, and there is a square hole on the side of the vertical rod next to the lower chord. It is used for the beam clamp to fix the beam. The material of the bailey panel is 16Mn, and each rack weighs 270kg. The "321" steel bridge is a prefabricated highway steel bridge. Its biggest feature is that the components are light and easy to disassemble and assemble. The prefabricated highway steel bridge is composed of truss type main girder, bridge deck system, connection system, and structural foundation. And equipped with dedicated erection tools. There is a small round hole at one end of the pin, and an insurance card is inserted during installation to prevent the pin from falling off. There is a groove at the top of the pin, and the direction is consistent with the direction of the small round hole. During installation, the groove is parallel to the upper and lower chords so that the insurance card can be smoothly inserted into the pin hole.

The above is a specific description of under what circumstances the strength and rigidity of the bailey panel will be improved.
