Technical field:

[0001] The utility model belongs to the field of bridge construction, in particular to a hoop device for bridge pier construction. Background technology:

[0002] In bridge construction, there are more and more bridges with square column structures for piers, and the requirements for safety, quality and progress of construction are becoming higher and higher. At present, the method commonly used for cast-in-place cap beam construction of square column piers is the full-span scaffolding method. The full-span scaffolding has the requirements of foundation bearing capacity, long scaffolding erection time, large material consumption, low construction efficiency and high safety risks. Therefore, the method of setting a hoop on the pier (hoop method) and then carrying out cap beam construction has gradually been used by people. The hoop method has the advantages of simple components, convenient installation and disassembly, fast turnover, and is not restricted by factors such as foundation and pier height. However, in the specific construction process, due to problems such as construction quality control or external factors on site, it is inevitable that there will be certain deviations in the construction size of the pier, which may cause a certain distance between the hoop and the pier, and the inner surface of the hoop is difficult to fully fit with the outer surface of the pier, resulting in a reduction in the effective vertical friction between the two, causing the hoop to easily slide downward under a large load, increasing the risk of safety construction. Utility model content:

[0003] The utility model aims to provide a hoop device for bridge pier construction, and overcomes the shortcomings of the above-mentioned prior art, which effectively solves the existing problem that the friction between the hoop and the pier is reduced due to the gap.

[0004] Contents of the utility model: A clamping device for bridge pier construction, comprising four clamping plates, the four clamping plates enclosing a square fastening area, the four clamping plates being used to be installed on four faces of the pier, docking assemblies being installed at both ends of the clamping plates, a gap compensation assembly being arranged on the clamping plates, the gap compensation assembly comprising a rubber block, a through opening being opened on the side wall of the clamping plate, the rubber block being placed in the through opening, a pressure plate being arranged on the outer wall of the rubber block, the two ends of the pressure plate being fixedly connected to the side wall of the clamping plate by a first bolt, and the pressure plate being used to rub the inner wall of the rubber block against the side wall of the pier against each other.

[0005] Furthermore, a plurality of springs are evenly installed on the inner side wall of the pressure plate, and the outer ends of the springs are fixedly connected to the outer side wall of the rubber block.

[0006] Furthermore, the rubber block and the through opening are uniformly in the shape of vertical bars.

[0007] Furthermore, the hoop plate is in a right-angle shape.

[0008] Furthermore, two gap compensation components arranged vertically are provided on the right-angled sides of the hoop plate.

[0009] Furthermore, the docking assembly includes a connecting vertical plate, one end of which is vertically fixedly connected to the side wall of the hoop plate, and two adjacent connecting vertical plates are fixedly connected by a plurality of second bolts that are equally spaced and vertically arranged.

[0010] Furthermore, a reinforcing plate is installed between the hoop plate and the connecting vertical plate.

[0011] Furthermore, the reinforcing plate is disposed between two adjacent second bolts.

[0012] The beneficial effects of the utility model are as follows: by arranging a gap compensation component on the hoop plate, the vertical friction between the hoop plate and the pier column is increased, thereby preventing the hoop plate from sliding downward from the pier column due to the gap when the load is large, thereby reducing the construction safety risk.

[0018] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0019] like Figures 1 to 4As shown, a hoop device for bridge pier construction comprises four hoop plates 1, the four hoop plates 1 enclose a square fastening area, the four hoop plates 1 are used to be installed on four faces of the pier 2, docking components are installed at both ends of the hoop plates 1, a gap compensation component is arranged on the hoop plates 1, the gap compensation component comprises a rubber block 3, a through opening 4 is opened on the side wall of the hoop plate 1, the rubber block 3 is placed in the through opening 4, a pressing plate 5 is arranged on the outer wall of the rubber block 3, the two ends of the pressing plate 5 are fixedly connected to the side wall of the hoop plate 1 by a first bolt 6, the pressing plate 5 is used to rub the inner wall of the rubber block 3 against the side wall of the pier 2, a plurality of springs 7 are evenly installed on the inner wall of the pressing plate 5, the outer end of the spring 7 is fixedly connected to the outer wall of the rubber block 3, and the rubber block 3 and the through opening 4 are evenly in the shape of vertical bars.

[0020] Specifically, by providing a gap compensation component on the hoop plate 1, the vertical friction between the hoop plate 1 and the pier column 2 is improved, thereby preventing the four hoop plates 1 from sliding down the pier column 2 due to the gap.

[0021] In actual use, the position of the hoop is determined according to the cap beam elevation and the bracket height, and the four hoop plates 1 are spliced ​​on the four faces of the pier column 2 through the docking assembly. The inner surfaces of the four hoop plates 1 and the outer surfaces of the pier column 2 generate the main vertical friction force, and the inner wall of the rubber block 3 located in the opening 4 of the hoop plate 1 and the outer wall of the pier column 2 generate additional vertical friction force, thereby maximally compensating for the vertical friction force lost by the gap between the hoop plate 1 and the pier column 2, and improving the vertical friction force between the hoop plate 1 and the pier column 2; continuously rotating the nut on the first bolt 6 can increase the pressure plate 5 exerts an extruding force on the rubber block 3, thereby further increasing the friction between the inner wall of the rubber block 3 and the outer surface of the pier column 2; the pressure plate 5 and the rubber block 3 are elastically connected by the spring 7, so that when the clamping plate 1 is disassembled after construction, the rubber block 3 is not easy to fall off, which is convenient for direct use again later, reducing the installation time of the gap compensation component, and when the rubber block 3 is worn due to friction after repeated use of the clamping device, the spring 7 can keep the inner wall of the rubber block 3 always in friction with the outer wall of the pier column 2; the vertical bar-shaped rubber block 3 can further increase its friction with the pier column 2.

[0022] like Figures 1 to 4As shown, the hoop plate 1 is in a right-angle shape, and two vertically arranged gap compensation components are provided on the right-angled sides of the hoop plate 1. The docking component includes a connecting vertical plate 8, one end of the connecting vertical plate 8 is vertically fixedly connected to the side wall of the hoop plate 1, and two adjacent connecting vertical plates 8 are fixedly connected by a plurality of second bolts 9 with the same spacing and vertically arranged. A reinforcing plate 10 is installed between the hoop plate 1 and the connecting vertical plate 8, and the reinforcing plate 10 is provided between two adjacent second bolts 9.

[0023] Specifically, by arranging two gap compensation components on the right-angled sides of the right-angled hoop plate 1, the friction between the gap compensation components and the pier 2 is increased.

[0024] In actual use, a number of second bolts 9 with the same spacing and arranged vertically can connect and fix the four right-angled hoop plates 1 on the pier 2; the two vertically arranged gap compensation components set on the right-angled sides of the right-angled hoop plates 1 can increase the friction with the surface of the pier 2, thereby further preventing the four hoop plates 1 from sliding down the pier 2 due to gaps.
