Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a Bailey beam limiting structure. Background Art

[0002] Bailey beams have the characteristics of strong spanning capacity and easy installation and dismantling. They are increasingly used in temporary structures such as piers, drilling platforms, etc. in cast-in-place box beams and underwater bridge construction. Bailey beams are usually erected horizontally, with I-beams and other steel sections erected on the upper chord of the Bailey beam as distribution beams. Panels are laid on the top of the distribution beams for vehicles to pass or as construction platforms. The lower chord at the lower end of the Bailey beam is erected on the load-bearing beam. The load-bearing beam supports the weight of the entire upper part of the column through the Bailey beam, so the stability of the connection between the Bailey beam and the load-bearing beam is particularly important.

[0003] The patent with application number 202222143597.8 discloses a Bailey beam limit device, including a limit frame fixedly installed on an I-beam, the limit frame including limit plate one, limit plate two and limit plate three, limit plate one and limit plate two are arranged in parallel, the width between limit plate one and limit plate two matches the width of the lower chord, limit plate one and limit plate two are symmetrically provided with locking components for locking the lower chord, one end of limit plate three is hinged to limit plate one, and the other end is fixedly connected to limit plate two; the locking component includes a plurality of staggered tightening bolts, the tightening bolts respectively pass through limit plate one and limit plate two and abut against the lower chord, and the tightening bolts are threadedly connected to limit plate one and limit plate two. The Bailey beam is fixed and limited by multiple tightening bolts against the side of the lower chord. Although this method avoids drilling holes on the lower chord, it can also limit and fix the Bailey beam in the horizontal and vertical directions of the lower chord. However, in the axial direction of the lower chord, since this method uses the friction between the tightening bolts and the side of the lower chord to limit and fix, when the panel is used as a construction platform or a vehicle passes by, the entire Bailey beam will vibrate. If the Bailey beam is vibrated, it is likely to shift in the axial direction of the lower chord, thereby posing a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem that the friction between the top bolt and the side of the lower chord is used to limit the position of the panel in the prior art.

It can be flexibly installed and disassembled by fixing the base on the load-bearing I-beam to achieve turnover use. The Bailey beam can be limited and fixed along the axial direction of the lower chord by the limiting plate 1 and the limiting plate 2 and the tightening screws 1 and 2 installed thereon, thereby preventing the Bailey beam from being offset along the length direction as a whole.

[0015] By means of the tightening screw rod three arranged on the support plate one and the tightening screw rods one and two arranged on the limiting plate one and the limiting plate two respectively, the lower chords of different widths and the Bailey frame vertical rods of different widths can be clamped and limited.
