Description

Limiting device for connecting Bailey beam and bearing beam

Technical Field

The utility model relates to a bridge engineering steel landing stage technical field especially relates to a stop device that bailey roof beam and bearing crossbeam are connected.

Background

The Bailey beam has the advantages of strong spanning capability, convenient installation and disassembly and the like, and is widely applied to large-scale temporary construction structures, such as construction trestles, construction platforms and the like. The temporary building structure usually adopts a steel pipe pile as a foundation, double-spliced or multi-spliced I-shaped steel bearing cross beams are erected at the top of the steel pipe pile, bailey beams are erected on the bearing cross beams, distribution beams are erected on the Bailey beams, and finally bridge decks are laid on the distribution beams to form a construction trestle or a construction platform for construction vehicles to pass.

Due to the actions of transverse wind load, braking of heavy-duty vehicles on the bridge, expansion caused by heat and contraction caused by cold of the Bailey beam caused by temperature and the like, after the Bailey beam is erected on the bearing cross beam, if corresponding fixing measures are not taken, the Bailey beam can generate transverse or longitudinal displacement and even has the risk of lateral overturning. The utility model discloses a grant utility model patent that publication number is CN 215518315U discloses bei lei roof beam installation node structure, and this structure utilizes the welding to restrict bei lei roof beam and take place lateral displacement and topple on bearing beam and the type of falling U shaped steel buckle of bucklei roof beam lower chord, utilizes the restriction relation that welds between bolt and the bearing beam of bei lei roof beam lower chord downside to restrict bei lei roof beam's longitudinal displacement. The disadvantages of this structure are: the bearing cross beam is generally positioned at the joint of the Bailey beam, the existence of the inverted U-shaped buckle causes that a connecting bolt of the Bailey beam is difficult to install or remove, and a bolt nail for limiting longitudinal displacement causes that the Bailey beam cannot freely stretch out and draw back under the action of thermal expansion and cold contraction, so that the Bailey beam generates larger secondary internal force; the utility model discloses a grant utility model patent that publication is CN210797236U discloses a bei lei liang limit structure, welds the spacing steel sheet and two connecting screw that hug closely the bei lei liang lower chord outside on the bearing crossbeam through two and limits the displacement and the toppling of bei lei liang. The structure has the defects similar to that of the utility model with the publication number of CN 215518315U, the limit steel plate causes the connecting bolt of the Bailey beam to be difficult to install or remove, and the connecting screw causes the Bailey beam to be incapable of freely stretching under the action of thermal expansion and cold contraction, so that the Bailey beam generates larger secondary internal force; the utility model discloses a grant utility model patent that publication number is CN 209194352U discloses a fixed knot between Bailey roof beam and the spandrel girder of Bailey support constructs, and this structure passes through the horizontal gag lever post of Bailey roof beam lower chord member both sides and sets up on horizontal gag lever post and adopts U type to ride on a horse bolt and the fixed vertical gag lever post of bearing crossbeam to restrict the displacement and the toppling of Bailey roof beam. The disadvantages of this structure are: the installation and the removal of the limiting device are manually installed by workers, the installation is inconvenient and has certain danger, and in addition, the limiting device fails because the structure deforms and the bolts are easy to loosen and fall off under the action of repeated vehicle loads.

Therefore, it is desirable to provide a position-limiting device that has a firm structure and convenient installation and disassembly, and the existence of the device itself does not affect the latch connection of the beret beam, so as to solve the above technical problems.
