Description

Technical Field

[0001] The utility model relates to the technical field of Bailey beams, in particular to a Bailey beam for road and bridge engineering. Background Art

[0002] Bailey beams, also known as Bailey frames, Bailey sheets or trusses, can be used for highway bridges, gantry crane assembly, guide beams, bridge erection machines, hanging baskets, etc. Bailey sheets have the characteristics of simple structure, convenient transportation, quick erection, large load capacity, good interchangeability and strong adaptability. Bailey sheets are welded by upper and lower chords, vertical bars and diagonal bars. The ends of the upper and lower chords have male and female joints, and there are pestle frame connection pin holes on the joints. The chord of the Bailey sheet is composed of two No. 10 channel steels (back to back). On the lower chord, there are several steel plates with round holes welded. There are bolt holes for connecting with the reinforced chord and double-layer trusses in the upper and lower chords. There are also four bolt holes for connecting the support frame in the upper chord. The two holes in the middle are for connecting the double or multiple rows of trusses with the same section. The two holes at both ends are for connecting across the section. When multiple rows of Bailey sheets are used as beams or columns, the joints of the upper and lower sections of Bailey sheets must be reinforced with support frames.

[0003] Multiple rows of Bailey plates are used as beams, and two Bailey plates are connected and fixed by connecting frames. However, the existing connecting frames are fixed, resulting in the need to combine and fix Bailey plates with different spacings with different connecting frames, which is less convenient. Therefore, a Bailey beam for road and bridge engineering is proposed to optimize the above situation. Utility Model Content
