Gansu Bailey Panel - Shandong Taiheng Engineering Company - Bailey Panel Truss

Product Details

What is the function of a Bailey panel? Many people may not know what a Bailey panel is. Below, the editor will give a brief description of what a Bailey panel is. A Bailey panel is welded from top and bottom chords, vertical members, and diagonal members. The ends of the top and bottom chords have male and female connectors, and the connectors have pin holes for truss connection. The chords of the Bailey panel are composed of two No. 10 channel steels (back to back). On the bottom chord, several steel plates with round holes are welded. On the top and bottom chords, there are bolt holes for connecting the reinforced chord and the two-layer truss structure. In the top chord, there are also four bolt holes for connecting the fixing bracket, of which the middle two holes are for connecting single-row or triple-row trusses at the same node, and the two holes on both sides are for connecting across nodes. When a triple-row Bailey panel is used as a beam or column, the joint of the upper and lower Bailey panels must be reinforced with a fixing bracket.
On the bottom chord, four crossbeam pads are provided, with tenons on top to fix the position of the crossbeam in the plan. At the end of the round steel beam at the top of the bottom chord, two oval holes are also provided for connecting the impact-resistant support rod. The vertical members of the Bailey panel are all made of No. 8 I-beams. On the side of the vertical member near the bottom chord, there is a round hole for fixing the crossbeam with a crossbeam clamp. The material of the Bailey panel is 16Mn, and one panel weighs 275kg. The "321" steel bridge is an assembled highway steel bridge. Its main features are: light components, easy disassembly and assembly, strong adaptability, and rapid completion with simple tools and manpower. It is suitable for five load classes: automobile-10, automobile-15, automobile-20, crawler-50, and trailer-80. The roadway width is 3.4m, and it can be assembled into simply supported beam bridges with various spans ranging from 8m to 63m, and can also form continuous beam bridges.

How is the Bailey panel installed?

For the Bailey frame installation, first assemble and connect the Bailey frames in groups on the ground. Mark the positions of the Bailey frames on the transverse I-beams every 90cm with red paint. Use a truck crane to lift the connected Bailey frames. Construction process: strip foundation construction → steel column welding → transverse I-beam installation and welding → Bailey frame installation → full scaffold erection. 2. Key construction points of each process. (1) Strip foundation construction: According to the planned layout, use a total station and steel tape to set out the position of the strip foundation. Excavate the foundation to the strongly weathered rock with an excavator, then stop formwork, tie reinforcement, and pour C30 concrete. Steel column installation can only proceed after the strength reaches 80%, and the concrete top surface is required to be flat. (2) Steel pipe column construction: Use υ529mm steel pipes with a wall thickness of 8mm and a length of 9m each, of which 2.4-3m is below the ground surface and about 6m is exposed. Weld stiffening steel plates of 10mm thickness at the top and bottom. The spacing of the column steel pipes is 3.5m. Installation uses a 25T truck crane under the command of a dedicated person. (3) H-beam installation: The H-beam is firmly connected to the top of the steel pipe column. Use 1cm thick steel plates processed into inverted "L" shaped connectors to weld the two together. During the H-beam installation, the levelness must be ensured, and the height of each row should be the same to ensure that the Bailey beams are not suspended at any contact point and the force is uniform.

 The 321 Bailey panel has the characteristics of simple structure, convenient transportation, quick erection, large load capacity, good interchangeability, and strong adaptability. The 321 Bailey panel steel bridge is an assembled highway steel bridge. Its features are: light components, easy disassembly and assembly, strong adaptability, and rapid completion with simple tools and manpower. It is suitable for five load classes: automobile-10, automobile-15, automobile-20, crawler-50, and trailer-80. The clear width of the bridge roadway is 3.7m, and it can be combined into various span simply supported bridges within the range of 9m to 63m.
