Description

Technical Field

[0001] The present invention relates to the technical field of ancient building repair, and in particular to an auxiliary tool for replacing wooden support columns of ancient buildings, specifically a light-load support column replacement auxiliary device for ancient buildings. Background Art

[0002] In the structure of ancient buildings, supporting columns are the main load-bearing components and are also the key components to maintain the entire ancient building structure. Therefore, in the process of repairing ancient buildings, the repair and replacement of supporting columns is an extremely important process.

[0003] Currently, support columns are mainly divided into heavy-load support columns and light-load support columns based on their load-bearing structure. Heavy-load support columns are mainly used to support heavy parts of the house, such as beams and brackets. They have a larger diameter and are mainly replaced and repaired in parts during repair to ensure the load-bearing capacity while maintaining the original appearance as much as possible. Light-load support columns are mainly used to support light parts such as eaves and small beams. They have a smaller diameter and are usually replaced with new support columns to achieve the desired repair effect.

[0004] During daily construction, when replacing light-load support columns, the structure above the support columns is usually lifted with the help of lifting equipment to provide space for removing the original support columns and placing new ones. However, for buildings with smaller spaces, lifting equipment cannot enter and the work can only be done manually. Scaffolding must be installed around the support columns to be replaced, and the support beams must be lifted up with the help of hydraulic jacks. Then, the support columns are replaced by lifting. The entire construction process is labor-intensive and has low construction efficiency. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides an auxiliary device for replacing light-load support columns of ancient buildings, which is not only suitable for indoor use but also greatly reduces labor intensity and improves construction efficiency.

[0006] The present invention is achieved through the following technical solutions, providing a light-load support column replacement auxiliary device for ancient buildings, comprising a main support, and a rotating sleeve mounted on the main support and rotatably connected to the main support, wherein the rotating axis of the rotating sleeve extends in the vertical direction, and at least two sets of support column clamping and fixing mechanisms are mounted on the rotating sleeve, and the support column clamping and fixing mechanisms are arranged at intervals along the circumferential direction; The upper end of the main bracket is rotatably connected to an adjustment sleeve, and the rotation axis of the adjustment sleeve is set in the vertical direction. The adjustment sleeve is fixed with a support arm extending above the original light-load support column to be replaced, and a hand hoist is hung on the support arm.

[0007] When using this solution, one set of support column clamping and fixing mechanisms is fixed to the support column to be replaced, and the other set of support column clamping and fixing mechanisms is fixed to the new support column. Then, the structure supported by the light-load support column to be replaced is lifted upward using a hand chain hoist. The rotating sleeve is rotated to remove the original light-load support column while the new support column is moved to the original light-load support column position. The lifted structure is then lowered. The angle of the support arm can be adjusted by providing an adjustment sleeve, which improves the adaptability of the device.

[0008] As an optimization, the top of the main bracket is equipped with a recessed groove that fits the adjustment sleeve. Several ball bearings are placed at the bottom of the recessed groove to support the adjustment sleeve. This optimization solution ensures the stability of the adjustment sleeve by preventing it from tilting during lifting. It also facilitates the installation and removal of the adjustment sleeve, which helps improve construction efficiency. The ball bearings also reduce friction when rotating the adjustment sleeve.

[0009] As an optimization, a compression sleeve is sleeved on the upper end of the main bracket, which is threadedly connected to the main bracket. The top plate of the compression sleeve has a through-hole for the adjustment sleeve to pass through. The outer wall of the adjustment sleeve is fixed with a stopper located within the compression sleeve and supporting the top plate of the compression sleeve. This optimization solution uses the compression sleeve to compress and secure the adjustment sleeve using the action of the threads, preventing the adjustment sleeve from rotating during construction.

[0010] As an optimization, the main bracket is a cylindrical structure, and the rotating sleeve is rotatably connected to the main bracket via a bearing. This optimization solution sets the main bracket as a cylindrical structure, which facilitates the installation of the adjustment sleeve and the rotating sleeve. The installation of the bearing improves the flexibility of the rotating sleeve during rotation, making it more labor-saving when rotating the rotating sleeve.

[0011] As an optimization, several anti-fall platforms are fixed to the outer wall of the main support, located below the rotating sleeve. These platforms are spaced circumferentially. This optimization solution prevents the rotating sleeve from falling if the bearing is damaged, ensuring construction safety.

[0012] As an optimization, the support column clamping and fixing mechanism includes a fixed arm fixed to the rotating sleeve and extending radially outward. Two opposing curved plates are fixed to the end of the fixed arm remote from the rotating sleeve. The two curved plates interlock to form an inner hole that fits the light-load support column. A flat section is fixed to the end of the curved plate remote from the fixed arm. The flat sections of the two curved plates are bolted together. This optimized support column clamping and fixing mechanism uses interlocking curved plates to clamp the existing and new support columns, making operation simple and avoiding damage to the surface of the new support column.

[0013] As an optimization, each set of support column clamping and fixing mechanisms consists of two pieces, arranged vertically, with their inner holes coaxial. This optimization increases the clamping distance of the support columns, further ensuring that the columns remain vertical, thereby reducing the lifting amplitude of the structure they support and significantly minimizing damage to the historic building.

[0014] As an optimization, the main bracket is also equipped with a support plate that extends below the inner hole of one of the support column's clamping and fixing mechanisms. The vertical projection of the inner hole is within the vertical projection of the support plate, increasing the support area for the new support column. This optimization solution provides support for the new support column by providing a support plate, further preventing the new support column from falling in its initial position.

[0015] As an optimization, the support plate is mounted on the main bracket, which is also equipped with an adjustment ring located below the support plate and threadedly connected to the main bracket. This optimization solution facilitates the adjustment of the support plate's height by providing an adjustment ring, thereby facilitating the adjustment of the new support column's height to accommodate stone piers of varying heights.

[0016] As an optimization, the bottom of the main support is equipped with four legs arranged in a rectangular shape. The legs extend upward into the main support and are threadedly connected to the main support. The lower ends of the legs are fixed to the load-bearing base. This optimization solution allows the height to be adjusted by rotating the legs, facilitating leveling and meeting the requirements of using uneven floors in ancient buildings.

[0017] The beneficial effects of the present invention are: the supported structure is lifted by a hand winch, which makes it easy to control the lifting range and avoid damage to the building structure. By rotating the rotating sleeve, the original light-load support column can be moved while the new support column is installed in place. The operation is simple, labor-saving, and improves construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0020] like Figure 1 The device shown is an auxiliary device for replacing light-load support columns of ancient buildings, including a main bracket 4 and a rotating sleeve 5 that is sleeved on the main bracket 4 and rotatably connected to the main bracket 4. The rotation axis of the rotating sleeve 5 extends in the vertical direction. At least two groups of support column clamping and fixing mechanisms 8 are installed on the rotating sleeve 5, and each support column clamping and fixing mechanism 8 is arranged at intervals along the circumferential direction.

[0021] The main support 4 of this embodiment is cylindrical in structure, and the rotating sleeve 5 is rotatably connected to the main support 4 via bearings. To prevent the rotating sleeve from slipping due to bearing failure over time, several anti-fall platforms 14 are fixed to the outer wall of the main support, located below the rotating sleeve 5. These anti-fall platforms 14 are arranged at intervals along the circumference to prevent the rotating sleeve from falling.

[0022] The upper end of the main bracket is rotatably connected to an adjusting sleeve 1, and the rotation axis of the adjusting sleeve 1 is set in the vertical direction. The adjusting sleeve 1 is fixed with a support arm 11 extending to the top of the original light-load support column 9 to be replaced, and a hand hoist 10 is hung on the support arm 11.

[0023] To facilitate installation of the adjustment sleeve, a recessed groove adapted to the adjustment sleeve 1 is provided at the top of the main bracket 4 in this embodiment. The lower end of the adjustment sleeve extends downward into the recessed groove, and a number of balls 19 are placed at the bottom of the recessed groove to support the adjustment sleeve. During use, the sidewalls of the recessed groove serve to stabilize the adjustment sleeve. The balls ensure stable support for the adjustment sleeve and reduce resistance during rotation, allowing for better adjustment of the support arm position, allowing the chain hoist to be moved above the original light-load support column.

[0024] In order to secure the adjustment sleeve after adjusting the position of the support arm, in this embodiment, a compression sleeve 18 is sleeved on the upper end of the main bracket 4. The compression sleeve 18 is connected to the main bracket 4 via threads. The top plate of the compression sleeve is provided with a through hole for the adjustment sleeve 1 to pass through. The outer wall of the adjustment sleeve 1 is fixed with a stopper 17 located inside the compression sleeve and supporting the top plate of the compression sleeve. When the compression sleeve is tightened, the threaded action causes the top plate of the compression sleeve to press downward against the stopper 17, thereby preventing the compression sleeve from rotating on its own.

[0025] The bottom of the main frame is equipped with four legs 16 arranged in a rectangular shape. The legs 16 extend upward into the main frame and are threadedly connected to the main frame. The lower ends of the legs are fixed to a load-bearing base. The load-bearing base is a flat plate with a cross-sectional area larger than the surface area of ​​the legs to prevent damage to the ground. During use, the length of the legs extending from the main frame can be adjusted by rotating the legs, thereby achieving leveling, meeting the requirements of uneven floors inside ancient buildings.

[0026] The support column clamping and securing mechanism 8 in this embodiment includes a fixed arm 12 fixed to the rotating sleeve 5 and extending radially outward. Two opposing curved plates 13 are fixed to the end of the fixed arm 12 facing away from the rotating sleeve. These curved plates 13 interlock to form an inner hole that fits within the light-load support column. A flat section is fixed to the end of the curved plate facing away from the fixed arm. These flat sections are bolted together. To prevent damage to the new support column, rubber pads are placed on the inner surfaces of the curved plates.

[0027] The support column clamping and fixing mechanisms of this embodiment are divided into two groups, which are used to clamp the original light-load support column 9 and the new support column 3 respectively. There are two support column clamping and fixing mechanisms in each group of support column clamping and fixing mechanisms. The two support column clamping and fixing mechanisms are arranged in the vertical direction, and the inner holes of the support column clamping and fixing mechanisms are coaxial, ensuring that the original light-load support column 9 and the new support column 3 are both in a vertical state, which is beneficial to reducing the lifting amplitude of the supported structure.

[0028] The main bracket is also fixed with a support plate 6 extending to the bottom of the inner hole of one of the support column clamping and fixing mechanisms. The vertical projection of the inner hole is located within the range of the vertical projection of the support plate. The inner hole corresponding to the support plate is used to clamp the new support column. The new support column is supported by the support plate, ensuring reliable support for the new support column. At the same time, it is convenient to adjust the height position of the new support column by adjusting the height of the support plate.

[0029] To facilitate adjustment of the height of the support plate, the support plate 6 of this embodiment is mounted on the main bracket 4. The main bracket 4 is provided with an adjustment ring 15 located below the support plate. The adjustment ring 15 is threadedly connected to the main bracket 4. The support plate is supported by the adjustment ring, and the height of the support plate can be adjusted by rotating the adjustment ring, thereby adjusting the height of the new support column to accommodate stone piers 7 of different heights.

[0030] The following takes the supported structure as the crossbeam 2 as an example to illustrate the method of using the device of this embodiment: when in use, move the main bracket to the side of the original light-load support column 9 to be replaced, and level it by rotating the legs. According to the height of the stone pier 7 under the original light-load support column, adjust the height of the support plate, and rotate the adjusting ring so that the upper surface of the support plate 6 is 2mm~3mm higher than the upper surface of the stone pier; rotate the adjusting sleeve 1 to rotate the support arm 11 to the top of the original light-load support column 9, rotate the tightening sleeve 18 to fix the adjusting sleeve 1, and wrap the chain of the hand hoist around the crossbeam 2 so that Lift the beam; place the new support column 3 on the support plate and secure it with one of the support column clamping and fixing mechanisms, ensuring that the new support column can move with the rotation of the rotating sleeve; secure the other support column clamping and fixing mechanism to the original light-load support column 9, pull the hand chain hoist to lift the beam 5mm to 10mm, then rotate the rotating sleeve 5 to move the original light-load support column out from under the beam. The new support column 3 moves under the beam as the rotating sleeve rotates, loosen the arc plate connecting bolts that secure the new support column, allow the new support column to fall on the upper surface of the stone pier, and then lower the raised beam. The provision of the arc plate 13 also facilitates fine-tuning of the new support column after loosening the connecting bolts, making the operation very convenient.

Technical features not described in the present invention can be achieved by or by adopting existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical solutions of the present invention and are not limitations of the present invention.
