Product Details

What matters should be noted in the design of form traveler for Bailey panel engineering applications?

The Bailey panel form traveler is usually composed of the main truss, suspension system, anchoring system, traveling system, working platform, bottom formwork frame, etc. To ensure construction quality and accelerate construction progress, the reasonable design of the form traveler is an important link. In the design of Guangdong Bailey panels, the form traveler is required to be light in weight, simple in structure, clear in force transmission, convenient to move, and also sturdy and stable, with small deformation, easy to anchor, assemble and disassemble, and to make full use of existing components; in addition, the form traveler is required to have high stiffness so that the formwork elevation can be quickly adjusted during concrete pouring; finally, the design should strive to allow the form traveler to be moved and positioned as a whole at one time, except for the slideway on the main truss.

　　1 Design principles of the form traveler

　　The form traveler is the main equipment for implementing cantilever pouring construction. It is a movable scaffold that can travel along the track and is suspended on the completed cantilever beam segment for the construction of the next beam segment, and so on cyclically until the beam segment pouring is completed.

　　Since the formwork installation, rebar tying, duct installation, concrete pouring, prestressing and duct grouting of the beam segment are all carried out on it and are high-altitude operations, and it is the load-bearing structure of the beam segment, the form traveler setup of Guangdong Bailey panels should not only ensure strength but also meet the requirements of small deformation, convenient traveling, anchoring, easy assembly and disassembly, and various construction operations, and attention should be paid to safety protection facilities.

　　2 Composition and properties of Bailey truss panel members

　　The main components of the Bailey truss panel consist of four types: truss panel, truss connecting pin, support frame, and truss bolt. The main load-bearing components of each Bailey truss panel are connected by the truss and support frame; the support frame uses a 90cm standard frame produced by 8# I-beam manufacturers. The entire truss panel is assembled from Bailey truss panels through end connecting pins.

Fixing method of Bailey bridge

For the Bailey panel, according to the bracket height and the bottom elevation of the bent cap, the position of the clamp hoop is determined on the pier column. Then the two semicircular clamp hoops are fixed to the pier column with high-strength bolts, with a layer of rubber belt between the hoop and the pier column. When tightening the bolts, first use the torque method for initial tightening, then use the angle method for final tightening, so that the bolts reach the predetermined tension, and the tightening torque shall not be less than 143.3 (kg?m). After bolt tightening, quality inspection shall be carried out, using a torque wrench to check, and tapping the bolts with a small hammer to judge by sound and torque whether any bolts are missed.

Brief introduction of Bailey bridge

Bailey bridge is a widely used and popular type of bridge in the world. It has the characteristics of simple structure, convenient transportation, rapid erection, and easy disassembly. At the same time, it has the advantages of large bearing capacity, strong structural rigidity, and long fatigue life. It can form various types of temporary bridges, emergency bridges, and fixed bridges with different spans and uses according to actual needs, and has the characteristics of few components, light weight, and low cost.

The truss connecting pin and safety pin of the Bailey panel have a small hole at the tapered end for inserting the safety pin. The two middle holes of the Yancheng Bailey frame are for connecting double-row or multi-row trusses in the same bay, and the two holes near both ends are for connecting across bays. The cutting speed of 4000 material can reach per minute Components: The truss is welded from upper and lower chords, vertical members, and diagonal members.   The chords of the truss are composed of two No. 10 channel steels (back to back), used to fix the position of the crossbeam on the plane: its processing width can be as narrow as 20 microns (0. On the lower chord, when multi-row trusses are used as beams or columns, the original name is "321" highway steel bridge.
