[0043] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0044] Please refer to the following: Figures 1 to 5 The present invention will now describe a column reinforcement method. The column reinforcement method includes the following steps:

[0045] Step S1: Level and repair the column.

[0046] Step S1 can be achieved through the following steps:

[0047] S1.1 Treat the surface of the column to expose the concrete surface;

[0048] The specific implementation method for this step can be as follows:

[0049] Use tools to chisel away the structural layer on the surface of the column until the concrete surface of the column is completely exposed.

[0050] S1.2 Grind the concrete surface smooth and perform repair and leveling work;

[0051] The specific implementation method for this step can be as follows:

[0052] Use grinding equipment such as angle grinders to grind the concrete surface; when the column has sharp edges, use grinding equipment to smooth the edges.

[0053] Then, the damaged areas on the concrete surface are repaired and leveled. The specific process is as follows: Use the same concrete mortar as the column to repair the damaged areas. After the concrete mortar has completely dried, use an angle grinder to level the surface.

[0054] S1.3. Position and lay out the lines on the column according to the preset requirements, and preset the placement of the first reinforcement and the second reinforcement by positioning and laying out the lines.

[0055] Step S2: Arrange several first reinforcement bodies 1 at intervals along the circumference of the column and fix the first reinforcement bodies 1. Then, place the second reinforcement body 2 in a preset position and connect and fix it to the first reinforcement body 1.

[0056] In this step, the length of the first solidified body 1 is the same as the length of the column.

[0057] The specific implementation method of this step is as follows: First reinforcing bodies 1 are installed at equal intervals along the circumference of the column. Then, a pre-fixed structure is used to limit the positions of multiple first reinforcing bodies 1. Specifically, the multiple first reinforcing bodies 1 can be gradually fixed by step-by-step tightening. Then, second reinforcing bodies 2 are placed at preset positions and connected and fixed to the first reinforcing bodies 1. Through the connection and fixation between the second reinforcing bodies 2 and the first reinforcing bodies 1, the second reinforcing bodies 2 and the first reinforcing bodies 1 form a reinforced frame.

[0058] Step S3: Seal the gaps between the first reinforcement 1, the second reinforcement 2 and the column; specifically, use weld sealant to seal the gaps between the first reinforcement 1 and the column, and the gaps between the second reinforcement 2 and the column, respectively.

[0059] Step S4: Fill the first solidification body 1 and the second solidification body 2 with slurry.

[0060] The process that can be achieved in this step is as follows:

[0061] The first reinforcing body 1 and the second reinforcing body 2 are both hollow structures. Each of the first reinforcing body 1 and the second reinforcing body 2 has a connecting hole on its surface that communicates with the hollow structure. The grouting pipe is inserted into the connecting hole to establish a connection between the grouting pipe and the hollow structure. Then, filling grout is injected into the first reinforcing body 1 and the second reinforcing body 2 through the grouting pipe. The reinforcement is completed after the filling grout has fully cured.

[0062] This column reinforcement method may also include: step S5, which involves fireproofing and corrosion protection treatment of the first reinforcing body 1 and the second reinforcing body 2. Specifically, the fireproofing and corrosion protection treatment can be achieved by spraying or applying a coating layer that provides fireproofing and corrosion protection to the surface of the first reinforcing body 1 and the second reinforcing body 2. Example

[0063] Let's take a cylinder as an example for explanation.

[0064] This column reinforcement method includes the following steps: First, use tools to chisel away the structural layer on the column surface until the concrete surface is completely exposed. Then, use grinding equipment such as an angle grinder to grind the concrete surface. Next, use concrete slurry, identical to that used for the column, to repair the damaged areas. After the concrete slurry has completely dried, use an angle grinder to level the surface. Finally, mark the positions on the column according to pre-defined requirements, and use these markings to pre-determine the placement of the first reinforcement body 1 and the second reinforcement body 2.

[0065] First reinforcing bodies 1 are installed at equal intervals along the circumference of the column. Then, a pre-fixing structure is used to limit the movement of multiple first reinforcing bodies 1. Specifically, all first reinforcing bodies 1 can be pre-fixed simultaneously using a clamping structure. Then, second reinforcing bodies 2 are placed in preset positions and connected and fixed to the first reinforcing bodies 1. Through the connection and fixation between the second reinforcing bodies 2 and the first reinforcing bodies 1, the second reinforcing bodies 2 and 1 form a reinforced frame. Then, the clamping structure is removed. In this step, the length of the first reinforcing body 1 is the same as the length of the column. The first reinforcing body 1 is a first arc-shaped plate. The first arc-shaped plate is hollow inside. The curvature of the first reinforcing body 1 matches the curvature of the column surface. The second reinforcing body 2 is a second arc-shaped plate. The second arc-shaped plate is hollow inside. The curvature of the second reinforcing body 2 matches the curvature of the column surface. Welding adhesive is used to seal the gaps between the first reinforcing body 1 and the column, and the gaps between the second reinforcing body 2 and the column, respectively. The interiors of the first reinforcing body 1 and the second reinforcing body 2 are both hollow structures. The surfaces of the first reinforcing body 1 and the second reinforcing body 2 are respectively provided with connecting holes that communicate with the hollow structure. The grouting pipe is inserted into the connecting holes to establish a connection between the grouting pipe and the hollow structure. Then, filling grout is injected into the first reinforcing body 1 and the second reinforcing body 2 through the grouting pipe. Reinforcement is completed after the filling grout has fully cured. Finally, fireproofing and corrosion protection treatment is achieved by spraying or applying a fire-retardant and corrosion-resistant coating layer to the surfaces of the first reinforcing body 1 and the second reinforcing body 2. Example

[0066] Let's take a rectangular prism as an example for explanation.

[0067] This method of column reinforcement includes the following steps:

[0068] Use tools to chisel away the structural layer from the surface of the column until the concrete surface is completely exposed. Use grinding equipment such as an angle grinder to grind the concrete surface; at the same time, use grinding equipment to smooth the edges.

[0069] Repair the damaged area using the same concrete mortar as that used for the column. After the concrete mortar has completely dried, use an angle grinder to level the surface.

[0070] Position and lay out lines on the column according to preset requirements, and preset the placement of the first reinforcement 1 and the second reinforcement 2 by positioning and laying out lines.

[0071] Four first reinforcement units 1 are respectively placed at the four corners of the column, and then gradually fixed by step tightening. Then, second reinforcement units 2 are placed in the preset positions and connected and fixed to the first reinforcement units 1. Through the connection and fixation between the second reinforcement units 2 and the first reinforcement units 1, the second reinforcement units 2 and the first reinforcement units 1 form a reinforced frame. The first reinforcement unit is an angle steel, which is hollow inside; the second reinforcement unit is a steel plate, which is also hollow inside. Both ends of the steel plate are connected and fixed to adjacent angle steel. Welding adhesive is used to seal the gaps between the first reinforcement unit 1 and the column, and the gaps between the second reinforcement unit 2 and the column. The surfaces of the first reinforcement units 1 and the second reinforcement units 2 are respectively provided with connecting holes that communicate with the hollow structure. Grouting pipes are inserted into the connecting holes to establish communication between the grouting pipes and the hollow structure. Then, filling grout is filled into the first reinforcement units 1 and the second reinforcement units 2 through the grouting pipes. The reinforcement is completed after the filling grout has completely cured. Then, fireproofing and corrosion protection are achieved by spraying or applying a coating layer that can achieve fireproofing and corrosion protection on the surface of the first solidified body 1 and the second solidified body 2. Example

[0072] Let's take a rectangular prism as an example for explanation.

[0073] Please refer to the following for information on this column reinforcement method. Figures 1 to 8 This includes the following steps:

[0074] Use tools to chisel away the structural layer from the surface of the column until the concrete surface is completely exposed. Use grinding equipment such as an angle grinder to grind the concrete surface; at the same time, use grinding equipment to smooth the edges.

[0075] Repair the damaged area using the same concrete mortar as that used for the column. After the concrete mortar has completely dried, level it using an angle grinder.

[0076] Positioning lines are laid out on the column according to preset requirements, and the placement of the first reinforcing body 1 and the second reinforcing body 2 is preset through positioning and laying out lines. The selected second reinforcing body 2 has a first receiving groove at the end close to the column. The first reinforcing body 1 has a second receiving groove at the end close to the column.

[0077] First, place eight first steel bars 5 into the second receiving groove. Then, the first steel bars, along with the first reinforcing bodies 1, are respectively set at the four corners of the column. Then, the multiple first reinforcing bodies 1 are gradually fixed by step tightening.

[0078] Then, a third reinforcing bar 6 is used, installed vertically at a certain distance from the end face of the column. The bottom end of the third reinforcing bar is fixed to the ground or the concrete structural layer.

[0079] Then, the second reinforcing body 2 is placed in the preset position and connected and fixed to the first reinforcing body 1. Through the connection and fixation between the second reinforcing body 2 and the first reinforcing body 1, the second reinforcing body 2 and the first reinforcing body 1 form a reinforced frame. At this time, the third reinforcing bar 6 is confined within the second receiving groove.

[0080] Then, multiple second reinforcing bars 7 are laid between adjacent second reinforcing bodies 2. The two ends of each second reinforcing bar are connected and fixed to the first reinforcing bar. Adjacent second reinforcing bars are also connected and fixed to each other. Furthermore, the second reinforcing bars are also connected and fixed to the third reinforcing bars.

[0081] The first reinforcing component is an angle steel, which is hollow inside; the second reinforcing component is a steel plate, which is also hollow inside. Both ends of the steel plate are connected and fixed to the adjacent angle steel.

[0082] The surfaces of the first reinforcing body 1 and the second reinforcing body 2 are respectively provided with connecting holes that communicate with the hollow structure. The grouting pipe is inserted into the connecting holes to establish communication between the grouting pipe and the hollow structure. Then, filling grout is injected into the first reinforcing body 1 and the second reinforcing body 2 through the grouting pipe. Reinforcement is completed after the filling grout has completely cured.

[0083] Then, fiber cloth mounting pieces 8 are installed on each of the four first reinforcement bodies 1. The fiber cloth mounting pieces 8 are used for quick installation of the fiber cloth. The fiber cloth is wound circumferentially around the column using the fiber cloth mounting pieces 8, specifically, winding around the column between adjacent second reinforcement bodies 2 each time. After the column is wound, concrete grout is filled into the gaps between adjacent second reinforcement bodies 2, and the concrete grout is allowed to set.

[0084] Then, fireproofing and corrosion protection are achieved by spraying or applying a coating layer that can achieve fireproofing and corrosion protection on the surfaces of the first solidified body 1, the second solidified body 2, and multiple fiber cloths.

[0085] This invention provides a column reinforcement method. Compared with existing technologies, a first reinforcement body 1 and a second reinforcement body 2 form a reinforcement frame. Filler material is then injected into the reinforcement frame, and the gap between the reinforcement frame and the column is simultaneously sealed. The reinforcement frame, filler material, and sealing structure work together to achieve column reinforcement. The reinforcement frame is less prone to damage, and the filler material, after curing, forms a solid, further strengthening the frame and improving the operational efficiency and service life of this column reinforcement method. The reinforcement frame and filler material also have a long anti-aging period, effectively extending the reinforcement life.

The reinforcing frame is configured to enclose the column and contact the surface of the column. The reinforcing frame has a hollow space inside. The filling structure 4 fills the hollow space. The sealing structure 3 is set in the gap between the columns of the reinforcing frame.

[0087] This invention provides a column reinforcement system that, compared to existing technologies, achieves column reinforcement through the combined action of a reinforcement frame, a filling structure 4, and a sealing structure 3. The reinforcement frame is less susceptible to damage, and the filling structure 4, being an integral part of the reinforcement frame, strengthens it, further improving the operational efficiency and service life of this column reinforcement method. The reinforcement frame and filling structure 4 also feature a long anti-aging cycle, effectively extending the reinforcement lifespan.
