The top of the two vertical wing plates is provided with an upper cover plate. On the upper cover, the double rows of Bailey sheets are integrated into one body through double channel steel. This technical solution adopts a flexible, convenient and foldable single-layer double-row Bailey sheet connection method, and uses the friction generated between the hoop and the column to provide the supporting reaction force of the upper structure, as the main supporting force structure, double-row The channel steel horizontal pin connection is designed between the Bailey sheets, which has high assembly and disassembly efficiency, and the double row of Bailey sheets can be arbitrarily extended in the width direction to set up the scaffold, which is safe for auxiliary work such as modeling of the main project of the cover beam pouring Spatial support.

Preferably, the hoop further includes a lower cover parallel to the upper cover, and reinforcing ribs intersecting horizontally and vertically are provided between the upper cover and the lower cover. In order to ensure sufficient strength of the supporting parts at both ends of the hoop, an upper cover plate and a lower cover plate are provided, and a reinforcing rib plate is provided in the middle.

Preferably, a rubber pad is provided between the hoop and the column. Improve the friction between the pier column and the hoop, and at the same time protect the concrete surface of the pier column.

As a preference, the diameter of the tubular structure formed by the two vertical semicircular arc plates of the hoop is equal to the outer diameter of the column fitting part, and the circumference of the hoop is smaller than the perimeter of the column fitting part.

As a preference, the vertical flanges at both ends of the hoop are formed into several grids by stiffening ribs crossed horizontally and vertically in both directions, and the bolts for connection are located in the small grids. An integral connection part is formed, which greatly enhances the supporting force of the part connecting the vertical wing.

As a preference, the double-row Bailey sheets are integrated by double-split channel steel through detachable pin connections. Easy installation and disassembly, flexible auxiliary configuration.

The beneficial effects of the utility model are: it solves the problems of long erection time, low efficiency, and high safety risk when the bridge pier adopts the cover beam construction; it has strong stability, simple and practical disassembly operation; it is convenient for the construction of horizontal purlin steel pipe scaffolding, etc. ; Make full use of the column, the construction is simple and not limited by the bearing capacity of the foundation.

Detailed ways

The technical solutions of the present utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

Referring to Fig. 1 and Fig. 3, this embodiment is a cover beam hoop device, which uses the column 1 as the force-bearing basis, and the hoop 3 on each column is designed as a bottom mold support, and finally achieves a safe and efficient cast-in-place cover beam 6 Require.

Specifically, based on a single column, as shown in Figure 2, a hoop 3 is installed at the top of the column 1. The hoop 3 is molded with a steel plate, and a tubular structure is formed by two vertical semicircular arc plates. The two ends of the arc plates are connected by vertical wing plates (vertical plates), and the top of the two vertical wing plates is provided with an upper cover plate 31, and the bottom is provided with a lower cover plate. The diameter of the pipe body formed by the two vertical semicircular arc plates is the same as the outer diameter of the matching part of the column 1, and the circumference is 10mm smaller than the circumference of the matching part of the column.
