How to use bailey frame to make moving mold frame?

May 17, 2022

Bailey beam is a truss beam assembled by a bailey frame, which is connected by a window and fixed by bolts. Its use because of rapid erection, strong mobility, wartime used for river, cliff erect simple bridge, is now used for engineering construction, such as gantry crane, construction platform, engineering access bridge, etc..

Bailey beam is made of bailey truss assemble girder, middle bailey truss to send more window for the connection of prefabricated, land bolt fixed main use: due to set up quickly, the maneuverability is strong, began to build simple highway embankment, leap more Bridges, now how to building construction, such as gantry crane, service platform construction, pavement of highway bridge project, etc. In the hanging basket construction, highway construction site across a river, you can also to show the pavement on the construction site, improve construction convenient.

The method of making mobile die frame is as follows:

1, along the top of the pier to both sides of the segmented cantilever construction, the general long span bridge hanging blue construction is commonly used in this method, now will be applied to the movable mold frame. Its principle is to use the weight of the continuous beam bending moment has the characteristics of the two sections, of about 0.5 L pier above the top of the first construction of the first negative bending moment, ask its weight of the bending moment is less than the mobile formwork permissible bending moment, when A section of box girder design strength and the casting after prestressed beam, from out of the block of moving die carrier, produced by its dead weight bending moment can be assumed by the beam segment itself, Its weight is transferred to the dock by bearings. For the second time, the mold frame does not move but only slides the formwork into the middle bending moment section of the span. Obviously, the amount of material moving the mold is greatly reduced at the moment when the second casting strip is four times less than the beam.

types of Bailey Bridge

2. The movable die frame adopted by this construction method is simple in structure, easy to master in technology, and can implement flow operation; Bailey frame has strong commonality and construction unit is standing equipment. When the weight, width and span of different concrete box girder roof and bottom plate change, it can be used for construction by adjusting the number of configuration pieces of beret frame.
