Description

Technical Field

[0001] This utility model relates to the field of high-pier bracket technology, and in particular to a convenient high-pier bracket device. Background Technology

[0002] In modern bridge construction, especially large-scale bridge projects, urban rail transit viaducts, and bridges spanning complex terrains such as valleys, rivers, and roads, ultra-high piers are an indispensable component. The high pier bracket is an important support system for the first block of the main beam and the subsequent cantilever casting of the main beam. The high pier bracket provides a stable working platform for the concrete pouring of the first block of the main beam, and construction workers can operate concrete conveying equipment on the bracket platform.

[0003] When it is necessary to complete the construction of multiple pier blocks in a short period of time, or when the road is rugged and narrow and the transportation of large pier brackets is difficult, traditional pier brackets are often installed by casting or welding on the spot. At the same time, the dismantling process often leaves behind cut steel, which is relatively complicated and time-consuming. Therefore, it is not conducive to the rapid implementation of bridge projects, and there is room for improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing high pier bracket, which is difficult to reuse the steel used for overall installation and disassembly, and is relatively cumbersome to operate. This utility model proposes a convenient high pier bracket device.

There are two sets of anti-shear screws, and each set of anti-shear screws has multiple screws distributed vertically. The two sets of anti-shear screws are located on two opposite sides of the high pier. Diagonal bracing supports are connected through adjacent upper and lower anti-shear screws. The multiple diagonal bracing supports are distributed in parallel at intervals. The diagonal bracing supports have a triangular steel frame structure. The top surface of the diagonal bracing support is a long strip plane. The outer end of each anti-shear screw is fitted with a square sand box and a nut to fix the diagonal bracing support. Multiple cylindrical sand boxes are fixed to the top surface of each diagonal bracing support. The top of the cylindrical sand boxes in the same set are jointly fixed with U-shaped channel steel. The top surfaces of adjacent U-shaped channel steels are jointly fixed with full-span supports.

[0006] Preferably, the inclined support has multiple rectangular pre-reserved holes evenly arranged on the upper and lower sides near the high pier, and the shear bolts pass through the pre-reserved holes.

[0007] Preferably, the interior of the square sandbox is pre-filled with gravel, the outer end of the anti-shear screw passes through the reserved hole located in the center of the square sandbox, the square sandbox and the nut are located on the outside of the diagonal brace, and the bottom of the square sandbox is provided with a bolt plug for discharging gravel.

[0008] Preferably, the top surface of the inclined support bracket is provided with multiple reserved holes, and the outer edge of the bottom surface of the cylindrical sand box is provided with multiple reserved holes. The reserved holes on the inclined support bracket and the reserved holes on the cylindrical sand box are connected and fixed by bolts.

[0009] Preferably, the U-shaped channel steel is connected and fixed by bolts and pre-drilled holes on the cylindrical sand box.

[0010] Preferably, the full-span scaffold is constructed from multiple horizontal and vertical supports. After being pre-assembled on the ground, the full-span scaffold is hoisted onto the U-shaped channel steel for fixation.

[0011] Preferably, the cylindrical sandbox is assembled from inner and outer sleeves, the interior of the cylindrical sandbox is pre-filled with sand and gravel, and a bolt plug is provided on the outer side of the bottom end of the cylindrical sandbox.

[0022] To address the shortcomings of existing technologies, such as the difficulty in reusing steel for the overall installation and disassembly of high-pier brackets, and the cumbersome operation, the following solution is disclosed, as follows: Figures 1-5 As shown:

[0023] A convenient high pier support device includes: shear bolts 7, which are reserved during the high pier grouting process. Two sets of shear bolts 7 are provided, and each set of shear bolts 7 has multiple bolts distributed vertically. The two sets of shear bolts 7 are located on opposite sides of the high pier. Diagonal bracing 1 is connected through adjacent vertical shear bolts 7. The multiple diagonal bracing 1 are distributed in parallel intervals. The diagonal bracing 1 has a triangular steel frame structure. The top surface of the diagonal bracing 1 is a long strip plane. Square sand boxes 3 and nuts 4 are fitted on the outer ends of the shear bolts 7 to fix the diagonal bracing 1. Multiple cylindrical sand boxes 2 are fixed to the top surface of the diagonal bracing 1 at intervals. U-shaped channel steel 5 is fixed to the top of the cylindrical sand boxes 2 in the same set. Full-span support 6 is fixed to the top surface of adjacent U-shaped channel steel 5.

[0024] The diagonal bracing 1 has multiple rectangular pre-reserved holes evenly arranged on the upper and lower sides near the high pier, and the anti-shear bolts 7 pass through the pre-reserved holes accordingly.

[0025] The inside of the square sand box 3 is pre-filled with gravel. The outer end of the anti-shear screw 7 passes through the reserved hole located in the center of the square sand box 3. The square sand box 3 and the nut 4 are located on the outside of the diagonal support bracket 1 in sequence. The bottom of the square sand box 3 is provided with a bolt plug for discharging gravel.

[0026] The top surface of the diagonal brace 1 is provided with multiple reserved holes, and the outer edge of the bottom surface of the cylindrical sand box 2 is provided with multiple reserved holes. The reserved holes on the diagonal brace 1 and the reserved holes on the cylindrical sand box 2 are connected and fixed by bolts.

[0027] The U-shaped channel steel 5 is connected and fixed by bolts and pre-reserved holes on the cylindrical sand box 2;

[0028] The full-span scaffold 6 is constructed from multiple horizontal and vertical supports. After being pre-assembled on the ground, the full-span scaffold 6 is hoisted onto the U-shaped channel steel 5 for fixation.

[0029] The cylindrical sand box 2 is assembled from inner and outer sleeves. The inside of the cylindrical sand box 2 is pre-filled with sand and gravel, and a bolt plug is provided on the outer side of the bottom end of the cylindrical sand box 2.

[0030] In this embodiment, during the grouting stage of the high pier, anti-shear bolts 7 are reserved on the pier body template according to the installation height of the bracket. After the high pier is solidified, the anti-shear bolt 1 is hoisted to one side of the high pier according to the position of the reserved hole on the diagonal support 1, and is assembled through with the corresponding anti-shear bolt 7. After the square sand box 3 filled with gravel is placed on the outer end of the anti-shear bolt 7, the square sand box 3 and the diagonal support 1 are locked and fixed with nuts 4. Then, multiple cylindrical sand boxes 2 are fixed on the top surface of the diagonal support 1 with bolts.
