Specific implementation mode
It is to be directed to great cantilever bent cap referring to the moving door frame in great cantilever Coping Construction in Fig. 1, Fig. 2 and Fig. 3, the present embodiment
Moving door frame system is arranged in 5 construction：Moving door frame system includes three units, is left cell, temporary location and the right side respectively
Side unit；Left cell has symmetrical structure form with right sided cell, is by two groups of 1 structures of independently arranged moving door frame respectively
At the distance between two groups of moving door frames 1 are the width for the car lane 6 for keeping normal pass；Moving door frame 1 is with removable
Universal wheel be castor；Temporary location 2 is with helix tube 21 for supporting upright post, and sandbox 22 is arranged at the top of helix tube 21,
Temporary location distribution beam 23 is set on sandbox 22, and the Bailey beam 3 for being laid with bent cap bed die 4 is supported on moving door frame system.
As shown in Figure 1, the structure setting of moving door frame 1 is in the present embodiment：Castor 11 is mounted on by I-steel and steel plate
The bottom on the door frame chassis 12 of composition, four sets of cannulated posts 13 are stood on door frame chassis 12, and cannulated posts 13 can using bolt
With adjusting post height, the twice transverse distribution beam 14 being in same level height is provided at the top of cannulated posts 13；
Bailey beam 3 is supported on transverse distribution beam 14, and at both ends in overhanging.
As shown in figure 4, the helix tube 21 in temporary location 2 is arranged along the horizontal as two rows, three have often been arranged；Helix tube 21
Between with channel steel reinforce connect, ensure the stability of supporting upright post.
As shown in Figure 3 and Figure 4, in the present embodiment, in the top of Bailey beam parallel arrangement top layer I-steel distribution beam, including
The side top layer I-steel 15 being at moving door frame top position and the middle part top layer work being at temporary location top position
Word steel 24, each top layer I-steel distribution beam be along bridge to arrangement, between top layer I-steel distribution beam and Bailey beam 3 use U-typed
Card is fixedly connected, and top layer I-steel distribution beam is made to connect into an entirety jointly for transmitting upper load with Bailey beam；Bent cap
Bottom plate 4 is laid in top layer I-steel distribution beam.The joint location of Bailey beam in the present embodiment in three units in each unit
Punishment is disconnected, forms separate stress unit, keeps structure more firm.
It, can be on construction road by each moving door frame row of two carriage sync pullings using the moving door frame of foot wheel
Into into next Coping Construction section, two moving door frames do not influence road travel, the effective solution problem of traffic data process.
Simultaneously by calculating, moving door frame system is about 2.13Mpa to basic compression, much smaller than the carrying of existing road surface and cushion cap
Power, therefore basis can not have to processing in construction, accelerate construction speed, saved construction cost.
