[0002] As an important part of road construction, bridge construction occupies a large proportion in modern engineering construction. At present, in the field of bridge construction, cylindrical pier cap beam casting brackets usually adopt the clamp method, which is divided into single clamp method and double clamp method. Although the single clamp method can complete bridge construction, its structure is complex, difficult to install and disassemble, and has high safety hazards; if the double clamp method without sand box is adopted, when dropping the mold, the shear bolts of the upper and lower clamps need to be loosened, and the mold is dropped by the deadweight of the template. When the bolts are loose, there is a risk of instantaneous sliding, which poses a safety hazard. Utility Model Content
[0003] The purpose of the utility model is to provide a fast, economical, safe and reliable supporting device for casting a single-column cap beam. The device can sink the sand box position to below the 40 I-beam crossbeam by sinking the sand box position, and utilize the upper and lower double hoop devices to meet the stress of cap beam casting, and can ensure a sufficiently safe sand box mold dropping process, and the structure is convenient and economical to install and disassemble.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a supporting device suitable for casting a single-column cap beam, comprising an upper hoop, a lower hoop, and a supporting frame, which also comprises a sand box and a sand box beam, wherein the upper hoop and the lower hoop are respectively fixed to the upper and lower parts of the single column; the sand box is placed on the upper hoop, 4 on each side, and is connected to the upper hoop through a sand box seat on the upper hoop; mutually perpendicular sand box beams, cross beams and distribution beams are sequentially placed on the sand box from bottom to top; the supporting frame is placed on both sides of the single column; the single-sided supporting frame comprises a cross brace and an oblique brace; the upper end of the oblique brace is connected to the cross beam, and the lower end is connected to the lower hoop; a cross brace is installed between the two oblique braces.
[0005] Preferably, upper clamp flanges are provided at both ends of the upper arc-shaped panel of the upper clamp, and a sand box seat is provided in the middle of the outer side of the panel.
[0006] Preferably, lower clamp flanges are provided at both ends of the lower arc-shaped panel of the lower clamp, and a Joule is provided at the upper end of the lower clamp flange, and the Joule is a rectangular plate.
[0007] Preferably, the sand box is in the form of a circular tube, and a bolt-type sand outlet is used at the bottom of the sand box.
[0008] Preferably, the upper clamp and the lower clamp are made of 12 mm panels, and the flange is made of 20 mm thick steel plate.
[0009] Preferably, the distribution beams are made of 16B I-beams and are arranged at intervals of 300mm-350mm.
[0010] The beneficial effects of the utility model are as follows: the supporting device of the single-column cap beam places the sand box above the upper hoop and below the cross beam through the support of the upper and lower hoops, thereby improving stability; at the same time, it is easy to install and disassemble, which can reduce the workers' high-altitude labor intensity and improve construction efficiency; the main materials are all profiles, with light weight, safety and reliability.

DETAILED DESCRIPTION
[0020] The following will be combined with the attached embodiment of the utility model Figure 1-8 , clearly and completely describe the technical solutions in the embodiments of the utility model.
[0021] The utility model embodiment provides a support device suitable for pouring a single column cap beam, referring to the attached Figure 1, including an upper hoop 5, a lower hoop 8, and a support frame, which also includes a sand box 4 and a sand box cross beam 3; the upper hoop 5 and the lower hoop 8 are respectively fixed to the upper and lower parts of the single column 17, and are used to support the distribution beam 1, the cross beam 2, the sand box cross beam 3 and the sand box 4, and the upper and lower hoops are fixed by M30 high-strength bolts; the sand boxes 4 are 4 on the left and right, placed on the upper hoop 5, connected to the upper hoop 5 through the sand box seat 11 on the upper hoop 5, and the sand box 4 is not fixed; the sand box cross beam 3, the cross beam 2 and the distribution beam 1 placed on the sand box from bottom to top are connected to each other by bolts, the sand box cross beam 3 and the cross beam 2 are perpendicular to each other, and the sand box cross beam 3 and the distribution beam 1 are parallel to each other; the support frame is placed on both sides of the single column; the single-sided support frame includes a cross brace 7 and an oblique brace 6; the upper end of the oblique brace 6 is connected to the cross beam 2, and the lower end is connected to the lower hoop 5; a cross brace 7 is installed between the two oblique braces 6, and the support frame is connected by a pin shaft.
[0022] In this embodiment, the installation method of the double clamp device is as follows:
[0023] S1. First, fix the upper hoop 5 with bolts, place the sand box 4, the sand box beam 3 and the distribution beam 1, and connect the main beam 2.
[0024] S2. Fix the lower hoop 8 with bolts, and the height between the top surface of the lower hoop 8 and the bottom surface of the main beam 2 is about 3 meters.
[0025] S3. Finally, connect the support frame through the pin shaft.
[0026] In this embodiment, the disassembly method of the double clamp device is as follows:
[0027] S1. Remove the side formwork first.
[0028] S2. Loosen the connecting bolts of the lower hoop 8 so that it can slide as a whole.
[0029] S3. Let the sand drain out of the sand box 4, so that the overall main beam 2 falls down, pull out the bottom mold horizontally, and hoist and remove the distribution beam 1, main beam 2, and support frame in sequence.
