The adjustable trolley formwork system has a high degree of automation, high equipment turnover efficiency, and safe and efficient overall movement, which effectively improves the level of industrialized construction, improves construction efficiency, improves construction quality, and ensures construction safety.

In this embodiment, the top mold panel 211, the side mold panel 224 and the corner mold panel are all made of a frame welded by steel sections and a steel panel fixed to the outside of the frame. The horizontal back ribs and vertical back ribs are made of two channel steels with openings facing outward and spaced apart, and steel sections welded and connected to the webs of the two channel steels. As shown in Figures 13 and 14, the top mold assembly includes a top mold panel 211, a plurality of horizontal back ribs 212 spaced apart at the bottom thereof, and a plurality of back rib quick connectors 213. The back rib quick connectors 213 are composed of a U-shaped bending plate 213a, a screw 213b penetrating the bending plate 213a, and a plurality of nuts. One end of the screw 213b is rigidly connected to the nut, and the other end thereof passes through the connecting hole of the bending plate 213a and the top mold panel 211 and is locked and fixed by the nut. The horizontal back rib 212 is buckled on the hook of the bending plate 213a, so that the horizontal back rib 212 can be vertically buckled on the bottom of the top mold panel 211. A plurality of transverse back ribs 212 are assembled to the top form panel 211 via back rib quick connectors 213 , which makes assembly and disassembly convenient and quick, thereby improving the installation efficiency of the formwork system 200 .

As shown in Figure 15, the side mold assembly includes a side mold panel 224, a second horizontal back rib 225, a first vertical back rib 226, a second vertical back rib 227 and a back rib quick connector. A plurality of second horizontal back ribs 225 are connected to one side of the side mold panel 224 through the back rib quick connector. Specifically, the screw of the back rib quick connector passes through the side mold panel 224 and is locked and fixed by a nut. The second horizontal back rib 225 is snapped into the hook at the end of the bending plate, so that the second horizontal back rib 225 can be vertically snapped into one side of the side mold panel 224. The fastening between the side mold panel 224 and the second horizontal back rib 225 is achieved by rotating and tightening the nut. The two first vertical back ribs 226 are vertically spaced apart and correspond to the positions of the two columns 11 supporting the door frame 10. The first vertical back rib 226 is bolted to the second horizontal back rib 225. The two channel steels of the first vertical back rib 226 are provided with long holes in corresponding positions. The end of the screw rod of the side mold elevator 42 is embedded in the gap between the two channel steels. The pin shaft passes through the long hole of the first vertical back rib 226 and the screw rod of the side mold elevator 42 and is tightened. The side mold elevator 42 can move vertically along the long hole of the first vertical back rib 226 without bearing the deadweight of the side mold assembly.

The second vertical back rib 227 is bolted to the second horizontal back rib 225. The two channel steels of the second vertical back rib 227 are provided with long holes in corresponding positions. The end of the adjustable cantilever beam 30 is embedded in the gap between the two channel steels. The pin passes through the long holes of the second vertical back rib 227 and the end of the adjustable cantilever beam 30 and is tightened. The adjustable cantilever beam 30 carries the side mold assembly and can drive the side mold assembly to move along the X direction and the Y direction to fine-tune the position.

As shown in Figures 10 to 12, the shape of the corner form panel matches the corner of the box culvert structure 2 to be cast. The two ends of the corner form frame 231 are provided with a connection hole 1 235 and a connection hole 236. The top surface of the corner form frame 231 near the connection hole 1 235 is provided with a slot 234.

The other end of the steel panel 232 of the corner form panel extends out of the corner form frame 231 as an extension end 237. The extension end 237 can be embedded in the notch of the steel panel end of the side form panel 224. Since the steel panels at the connection between the top form panel 211, the corner form panel and the side form panel 224 are overlapped in sequence, the template panel connection can be closely connected, ensuring the casting quality of the box culvert concrete structure.

As shown in Figures 10 and 11, the corner mold lifting machine 50 includes a screw rod 51, a connecting rod 52 connected to one end of the screw rod 51, a spiral drive device 54 threadedly connected to the other end of the screw rod 51, and an upper support 55 fixed to the end of the spiral drive device 54.

The downward pressure support includes a U-shaped support frame 35, an adjustable screw 36 connected to the top of the support frame 35, a second bearing 37 arranged at the bottom of the adjustable screw 36 and connected to the support frame 35 pin, and Axis pressure block, the other end of the cantilever beam 31 passes through the support frame 35 and is located at the bottom of the second bearing 37 and the shaft pressure block. The support bracket and the downward pressure bracket are both bolted to the cantilever beam support frame 18. The two ends of the cantilever beam 31 are respectively provided with a pin hole 1 38 and a pin hole 2 39. The pin hole 1 38 of the cantilever beam 31 close to the box culvert structure 2 to be cast is connected to the second vertical back rib 227 of the side mold assembly. A stopper (not shown in the figure) is installed in the pin hole 2 39 at the other end of the cantilever beam 31 to prevent the cantilever beam 31 from sliding out of the downward pressure bracket.

Due to the addition of a winch and anchor 500, the supporting frame 100 and the formwork system 200 are controlled by traction of the wire rope 510 to automatically move to the next construction section along the extension direction of the construction route of the box culvert structure 2 to be cast, and the movement is efficient and safe.
