Description

Technical Field

[0001] The utility model relates to the field of road and bridge construction, in particular to a road and bridge construction template supporting device. Background Art

[0002] An existing patent (Announcement No. CN208039059U) proposes a support device for road and bridge construction formwork, comprising a formwork, a fixed plate, a support rod, and a mounting plate. The fixed plate is connected to the formwork on both sides via fixing nails. The fixed plate has a positioning plate slot inside. The support rod has a positioning plate on top, which adapts to the positioning plate slot. The positioning plate is connected to the positioning plate slot via positioning nails. The positioning plate slot has a positioning protrusion on the top. The positioning plate has a positioning protrusion slot on the top, which adapts to the positioning protrusion. The positioning protrusion is connected to the positioning protrusion slot. The formwork has a reinforcement rod on the bottom, which adapts to the mounting plate. The left side of the mounting plate is connected to the reinforcement rod, which is in turn connected to the mounting plate and then to a reinforcement nut. The reinforcement nut and the reinforcement rod engage with each other. However, the support structure of this device is directly connected and fixed to the formwork, making it inconvenient for later demolding. Summary of the Invention

The connecting ear 05 connects the lower part of the rotating template 04 to the axis of the construction template 01. The rotating template 04 can be rotated and opened. The three rotating templates 04 are installed on the three sides of the construction template 01 and cooperate with the construction template 01 and the template side panels 02 to form the construction parts. The three rotating templates 04 are set to a rotatable and openable structure. When the workpiece is demoulded, it is easier to push the workpiece out of the template by opening the three rotating templates 04. The three rotating templates 04 are divided on the side of the construction template 01. The rotating template 04 is in contact with the template side panels 02, and the adjacent rotating templates 04 are in contact with each other. The upper surfaces of the rotating template 04 and the template side panels 02 are aligned, and the outer side surface of the construction template 01 is in contact with the rotating template 04.

[0019] Example 2:

[0020] The upper portion of the U-shaped pad 07 of the present invention is provided with a No. 3 side connecting ear 08, the lower portion of the rotating push plate 14 is connected to the No. 3 side connecting ear 08 through the No. 3 rotating shaft 25, the lower portion of the rotating push plate 14 is axially connected to the U-shaped pad 07, the rotating push plate 14 is rotatable, the No. 4 side connecting ear 19 is connected to the rotating support plate 18, the upper portion of the rotating push plate 14 is connected to the No. 4 side connecting ear 19 through the No. 2 rotating shaft 20, the upper portion of the rotating push plate 14 is axially connected to the rotating support plate 18, the rotating support plate 18 is rotatable, the side surface of the rotating support plate 18 is fitted with the rotating template 04, the construction template 01 is inserted into the U-shaped pad 07, and the U-shaped pad 07 is aligned with the lower surface of the construction template 01.

[0021] Example 3:

[0022] The U-shaped pad 07 of the present invention has a vertical fixing plate 09, and the side of the vertical fixing plate 09 has a circular boss 10. The threaded push rod 11 is adapted to the circular boss 10, and the threaded push rod 11 passes through the circular boss 10. The threaded push rod 11 rotates in the circular boss 10. The side of the threaded push rod 11 is connected to the handle 12, and the threaded push rod 11 has a top ball 13. The side of the rotating push plate 14 has a push plate side plate 15, and the side of the circular slider 17 is in contact with the push plate side plate 15.
