Bailey beam and distribution beam connecting device suitable for multiple occasions

Abstract

The invention relates to the technical field of bridge cast-in-place box beam formwork support system erection construction, in particular to a bailey beam and distribution beam connecting device suitable for multiple occasions, the bailey beam and distribution beam connecting device comprises a pressing piece and two fixing rods arranged side by side, each fixing rod comprises a straight rod section and a hook-shaped section connected to one end of the straight rod section, the other end of each of the two straight rod sections is detachably connected through the pressing piece, the bailey beam and distribution beam connecting device further comprises a connecting rod for fixedly connecting the two fixing rods, and the connecting rod is of a telescopic structure. The connecting device is easy to operate and convenient to use, a user can directly bend down to insert the connecting device from a gap of the bailey beam when standing on the upper portion of the bailey beam, the hook-shaped section hooks and fixes the bailey beam, the problem that U-bolts cannot be directly inserted and fixed from the upper portion is solved, the distance between the two fixing rods can be freely adjusted through the connecting rod of the telescopic structure, and the device is suitable for multiple occasions.

Description

technical field [0001] The invention relates to the technical field of construction of a bridge cast-in-place box girder formwork support system, in particular to a connecting device for a Bailey beam and a distribution beam applicable to multiple occasions. Background technique [0002] Bailey beams have the advantages of rapid erection and strong mobility, and are widely used in engineering construction processes, such as construction platforms, engineering access bridges, temporary bridges across rivers and support platform foundations. The Bailey beam is a truss beam assembled from Bailey frames, with multiple truss units 6a, such as figure 1 As shown, each truss unit 6a includes an upper chord 61 and a lower chord 62, a plurality of vertical support rods 63 are vertically arranged between the upper chord 61 and the lower chord 62, and the upper chord 61 is connected to the vertical The support bar 63 is reinforced, and the truss unit structure that connects the lower c...

Problems solved by technology

[0004] One of the purposes of the present invention is at least to address the fact that in the prior art it is impossible to integrally reinforce the overlapping joints at the joints between the Bailey beam and the distribution beam, and at the overlapping joints there are many supporting structures and the size of the transverse reinforcement is relatively small. For the problem that it is too large to be reinforced, it provides a connection device between Bailey beam and distribution beam that is suitable for many occasions. The connection device between Bailey beam and distribution beam can integrate the distribution beam and Bailey beam at the same time type reinforcement, and the connecting device between the Bailey beam and the distribution beam can also be used at the connection node of the top chord of the Bailey beam and where there are many structures at the connection node, so that the connection between the distribution beam and the Bailey beam is firm and avoids Problems affecting structural safety such as distribution beam collapse, overturning and displacement of distribution beam relative to Bailey beam occurred
