As shown in figure 9, stripper apparatus 4 is by the lead screw 42 that is fixed on the sliding rail 41 at 22 edge of the second counterdie and is slidably connected with sliding rail 41
3 side of side mode is fixed in composition, 42 one end of lead screw, in use, lead screw 42 is slided along sliding rail 41, by side mode 3 and prefabricated bridge floor
Plate separation.
As shown in fig. 6, being provided with the first positioning hole 31 and the second through-hole 32 of positioning vertical bar in side mode 3.
As shown in Figure 7 and Figure 8, several core films 5 are fixed on the inside of side mode 3 of the invention, core film 5 is in dovetail composition
Several second location holes of vertical bar positioning are provided on hollow structure, core film 5 and the side and its corresponding side of the fixation of side mode 3
51, the two sides vertical with side mode 3 be provided with for transverse bar positioning several locating slots 52, second location hole 51 be located at side mode
First positioning hole 31 on 3 matches, the common positioning for completing vertical bar.
After the completion of prefabricated bridge, in order to which prefabricated bridge and apparatus of the present invention to be kept completely separate, it is arranged below pedestal 1
There are equally distributed several lifting devices 6, distribution arrangement is identical as the direction of groove 211.
Embodiment 2: the structure based on embodiment 1, the present invention have made the prefabricated mould of following specification, specific preparation method
It is as follows:
Crossbeam 12,11 system of stringer are constituted using I-steel, channel steel, foundation pit, highly about 1.2m are set below pedestal 1, just
It is applied in bolt stubborn.Before prefabricated mould assembling, 1 drum crossbeam of pedestal and ground embedded board are bolted, it is total to adjust pedestal 1 by bolt
Body flatness.
It include middle part bottom for convenient for the positioning of T shape preburied component assembling, pedestal 1 and 2 coupling part of bed die are divided into three parts
Seat and the avris pedestal for being located at central seat two sides, counterdie are equally also classified into the middle part counterdie above central seat and are located at
The avris counterdie of middle part counterdie two sides, pedestal 1 are welded as a whole with bed die 2.
As shown in figure 11, it forms the first counterdie 21 of counterdie 2 and the second counterdie 22 makes of two layers of 12mm steel plate, setting is used
In the groove for inlaying T shape preburied component, for positioning embedded board and T shape preburied component；As shown in Figure 10, two sides prefabricated board, which becomes, cuts
It is realized at face by steel plate bending, bed die 2 opens up out the first venthole 23 by 2m spacing in prefabricated Board position, and pre-embedded steel slab is corresponding
Two parallel the first grooves 211 passed through convenient for T shape web are arranged, it is ensured that preburied component upper surface and bed die in assembled position
Upper surface is concordant.For the precise positioning for ensuring T shape preburied component, the second counterdie 22 is broken as three parts in T shape built-in fitting position,
It is positioned according to built-in fitting spacing, forms notch 221.It is subsequently mounted the demoulding hydraulic cylinder as lifting device 6.
As shown in figure 12, side mode 3 offers first positioning hole 31, and core model 5 opens up the second location hole for reinforcing bar positioning
51, core model 5 uses Split type hollow core model at dovetail concave station position, opens up the locating slot 52 for accommodating reinforcing bar, is mortar leakage prevention,
Locating slot 52 in core model 5 is blocked with sealant.When side mode 3 positions, the lead screw 42 of side mode 3 is shifted onto installation site, side mode 3 and bottom
Pin is fixed after being compressed between mould 2 with the sliding rail 41 of stripper apparatus 4, is fixed between side mode 3 with loose joint bolt.Air vent spiral shell is installed
After filling in and steel mesh being installed, core model 5 is assembled.
As shown in figure 13, when steel mesh assembles, reinforcing bar is first penetrated into screw shell, penetrates thread on the outside of side mode 3
It is connect by first positioning hole 31 with the screw shell other end, realizes reinforcing bar positioning.Thread is penetrated on the outside of core model, is passed through
3 second through-hole 32 of side mode penetrates core model second location hole 51 and connect with the screw thread steel sleeve other end, realizes reinforcing bar positioning.
As shown in figure 14, it when mold is removed, is carried out according to the sequence of side mode 3, core model 5, bed die 2.
Firstly, all threads between side mode 3, core model 5 and steel mesh are removed, with 42 edge of lead screw of stripper apparatus 4
Sliding rail 41 pull out side mode 3, core model 5 is taken out with crowbar.
The connection bolt that bed die 2 is used to fix T shape built-in fitting is removed, the stopple of the first venthole 23, starting lifting are removed
