Machine lifting I beam connecting plates make on the top surface that it falls within two laterally adjacent I beams of bridge floor.
Specifically, setting up flange plate support and flange plate on the horizontal outermost I beams in left and right of bridge floor in the step 3
The method of bed die is：The upper and lower part of the flange plate support is individually fixed in under by the upper panel of I beams by screw rod
In portion's panel, edge of a wing plate bed die is layed on the top surface of flange plate support.
Specifically, being embedded with the screw rod in the upper panel and lower panel of the I beams, the screw rod is located in I beams
One end be connected with embedded nut, one end that the screw rod is located at outside I beams is connected with support location nut through flange plate support.
The beneficial effects of the invention are as follows：Connecting plate is provided between I beams, laying bracket and bottom only at the Board position of the edge of a wing
Mould, floorings cast-in-place construction is most of to be carried out on prefabricated board, and safety of structure is good.Only need to remove the support at the Board position of the edge of a wing
And bed die, remainder need not carry out support and install with removing, and difficulty of construction is small, sets up support few.Reduced by connecting plate
The task difficulty of high-altitude construction, short construction period.The curved muscle connection reinforcing bar of longitudinal shear resistance is provided with connecting plate simultaneously and causes connection
Plate turns into a part for floorings permanent structure, and common stress is effective against the longitudinal shear at overlapping, reduces concrete square
Amount, economic technology cost performance is high.
