[0011] A positioning and cutting table is pre-processed and manufactured. The positioning and cutting table includes a table surface, and a circular positioning plate is connected to the top of the table surface. The positioning plate is cut with four sets of equally spaced slots along the circumference. The four sets of slots divide the positioning plate into four sets of arc-shaped plates. A first set screw is threaded to the middle of each set of arc-shaped plates. When the first set screw is tightened, the ends of the first set screw are located on the same circle.

[0012] When using it, select a tubular steel ring of appropriate size, place the steel ring on the positioning plate area on the table, tighten the first set screw so that the end of the first set screw supports the outer wall of the steel ring, realizing the self-centering of the steel ring; according to the position of the groove, mark the positioning line on the outer wall of the steel ring, and cut the steel ring according to the marked line to form four sets of arc-shaped clamps.

[0013] S2: Weld the first connecting plate and the second connecting plate to both ends of the clamp;

[0014] The first and second connecting plates are cut to size according to the design dimensions and drilled at the design positions to create mounting holes, through hole I and through hole II.

[0015] A welding auxiliary table is prefabricated, comprising a table plate, on the top surface of which is welded an arc-shaped limiting plate, the arc of which matches the arc of the clamp; a fixing seat welded to the table plate is provided on one side of the limiting plate, with a gap between the limiting plate and the fixing seat; the fixing seat is threaded with a second set screw; two sets of positioning clips for positioning the two ends of the clamp are also welded to the table surface, the positioning clips being angle irons welded to the table surface, and the end positioning clips of the clamp being fixed at the angle irons; two sets of guide plates are also welded to the table surface for guiding and positioning the positions of the first connecting plate and the second connecting plate;

[0016] When using, press the clamp tightly against the limiting plate, and position both ends of the clamp at the angle iron; tighten the second set screw to tighten and fix the positioned clamp.

[0017] The first connecting plate is placed tightly against one of the guide plates, and the end of the first connecting plate is aligned with the end of the clamp. Then welding is performed to complete the welding and fixing of the first connecting plate.

[0023] 2. The support frame is connected with high-strength bolts, and workers use electric wrenches for installation, which reduces the time workers spend working at heights and improves safety.

[0024] 3. During the installation of the bracket, a lifting vehicle is used on site to assist workers in their work. This facilitates movement, improves safety, and shortens the working time.

[0025] 4. The connection between the support frame and the steel pipe column requires no welding or gas cutting on site, which improves safety and reduces material loss and energy consumption.

[0026] 5. Rubber padding is placed between the clamp and the steel pipe column to improve the connection firmness and enhance shock absorption and seismic resistance.

[0027] 6. The equipment can be quickly dismantled after construction and reused, improving recycling rate, reducing costs, and increasing work efficiency.

[0028] 7. The bracket can be manufactured by ourselves. With the self-made positioning and cutting table, the steel ring can be quickly positioned and cut. The positioning and cutting table has a first set screw. When the first set screw is tightened, the ends of the first set screw are located on the same circle. This can ensure that the steel ring is self-centered and clamped, and ensure that the steel ring and the positioning plate are coaxially set. This ensures that the subsequent line drawing and cutting are accurate. The structure is simple, the positioning is convenient, the cutting and blanking are easy, and the work efficiency can be improved.

[0029] 8. A self-made welding auxiliary table is used. The welding auxiliary table has a limiting plate and a second set screw.

Detailed Implementation

[0043] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] Example 1

[0045] like Figure 1-4As shown in the figure, this embodiment proposes a detachable bracket for reinforcing a steel pipe column 1, including four sets of arc-shaped clamps 2. The clamps 2 are detachably connected end to end, forming a ring structure that can wrap around the steel pipe column 1. One end of the clamp 2 is connected to a first connecting plate 3, and the other end of the clamp 2 is connected to a second connecting plate 6. Mounting holes 5 are opened at corresponding positions on the first connecting plate 3 and the second connecting plate 6. High-strength bolts are inserted through the mounting holes 5. Adjacent first connecting plates 3 and second connecting plates 6 are connected by high-strength bolts. The second connecting plate 6 is also provided with a through hole I61 for bolting a slanted channel steel 7. The second connecting plate 6 is also provided with a through hole II62 for bolting a horizontal channel steel 8.

[0046] In use, the four clamps 2 are connected by high-strength bolts to form an integral clamp ring, which is then fitted and fixed onto the steel pipe column 1.

[0047] As a preferred option, several reinforcing ribs 4 are welded between the first connecting plate 3 and the clamp 2; several reinforcing ribs 4 are also welded between the second connecting plate 6 and the clamp 2 to improve the overall strength and stability.

[0048] As a better option, the inner wall of the clamp 2 is lined with rubber. The rubber (rubber lining between the clamp 2 and the steel pipe column 1, not shown in the figure) increases the friction with the steel pipe column 1, prevents vertical slippage, and provides shock absorption and seismic resistance.

[0049] The horizontal channel steel 8 connects adjacent columns horizontally in the axial and normal directions; the diagonal channel steel 7 connects adjacent columns vertically in a reinforcing manner, thus achieving a scissor bracing effect.

[0050] In this embodiment, the width of the second connecting plate 6 is the same as the width of the first connecting plate 3. In addition, in order to facilitate the connection of the opening, the length of the second connecting plate 6 is greater than the length of the first connecting plate 3, forming an extension section. Through holes I61 and II62 are opened at the location of this extension section.

[0051] The above-mentioned bracket is used as follows:

[0052] 1. Construct steel pipe columns according to the support design plan;

[0053] 2. Install the four clamps 2 to the designed height, and connect the clamps 2 into a ring using high-strength bolts;

[0054] 3. The horizontal channel steel 8 and the inclined channel steel 7 are installed by bolting.

[0055] 4. Tighten the high-strength bolts to form the entire support structure.

[0056] The support in this embodiment has the following advantages:

[0057] 1. The brackets can be mass-produced in the processing area, which is easy to process and ensures processing quality and efficiency.

[0058] 2. The support frame is connected with high-strength bolts, and workers use electric wrenches for installation, which reduces the time workers spend working at heights and improves safety.

[0059] 3. During the installation of the bracket, a lifting vehicle is used on site to assist workers in their work. This facilitates movement, improves safety, and shortens the working time.

[0060] 4. The connection between the support frame and the steel pipe column 1 requires no welding or gas cutting on site, which improves safety and reduces material loss and energy consumption.

[0061] 5. Rubber padding is placed between clamp 2 and steel pipe column 1 to improve the connection firmness and enhance shock absorption and seismic resistance.

[0062] 6. The equipment can be quickly dismantled after construction and reused, improving recycling rate, reducing costs, and increasing work efficiency.

[0063] Example 2

[0064] like Figure 5-10 As shown in the figure, this embodiment also proposes a processing method for a detachable bracket for reinforcing the steel pipe column 1, including the following steps:

[0065] S1: Processing and manufacturing clamps 2

[0066] The aforementioned clamp 2 is manufactured using self-made tools, which saves costs. A positioning cutting table is pre-fabricated in the processing area. The positioning cutting table includes a table surface 9, and a circular positioning plate is connected to the top of the table surface 9. The positioning plate is cut with four sets of equally spaced slots 12 along the circumference. The four sets of slots 12 divide the positioning plate into four sets of arc plates 10. A first set screw 11 is threaded to the middle of each set of arc plates 10. When the first set screw 11 is tightened, the ends of the first set screw 11 are located on the same circle. The purpose of this setting is to achieve self-centering positioning of the workpiece to be processed after tightening all the first set screws 11.

[0067] When using it, select a tubular steel ring 13 of appropriate size. The steel ring 13 is the raw material for making the clamp 2. Place the steel ring 13 in the area of ​​the positioning plate on the table 9. Select a first set screw 11 of appropriate length and tighten the first set screw 11 so that the end of the first set screw 11 supports the outer wall of the steel ring 13, realizing the self-centering of the steel ring 13. According to the position of the groove 12, mark the positioning line on the outer wall of the steel ring 13. When drawing the line, a drawing pen (stone pen, marker pen) can be used to assist in drawing the line.

[0068] The steel ring 13 is cut according to the marked position to form four sets of arc-shaped clamps 2.

[0069] S2: Weld the first connecting plate 3 and the second connecting plate 6 to both ends of the clamp 2;

[0070] The first connecting plate 3 and the second connecting plate 6 are cut and drilled according to the design dimensions, and mounting holes 5, through holes I61 and through holes II62 are made.

[0071] A welding auxiliary table is prefabricated to assist welding and improve efficiency. The welding auxiliary table includes a table plate 14, on the top surface of which is welded an arc-shaped limiting plate 15. The arc of the limiting plate 15 matches the arc of the clamp 2. A fixing seat 16 is provided on one side of the limiting plate 15 and welded to the table plate 14. There is a gap between the limiting plate 15 and the fixing seat 16. The fixing seat 16 is threaded with a second set screw 17. The table surface 9 is also welded with two sets of positioning clips for positioning the two ends of the clamp 2. The positioning clips are angle irons 19, which are welded to the table surface 9. The end positioning clips of the clamp 2 are located at the angle irons 19. The angle irons 19 are readily available and easy to process and manufacture.

[0072] The tabletop 9 is also welded with two sets of guide plates 18, which are used to guide and position the first connecting plate 3 and the second connecting plate 6. The guide plate 18 is a rectangular plate structure that serves as a guide and positioner.

[0073] When in use, clamp 2 is pressed tightly against limiting plate 15, and both ends of clamp 2 are positioned and locked at angle iron 19; tighten the second set screw 17 to tighten and fix the positioned clamp 2.

[0074] The first connecting plate 3 is pressed tightly against one of the guide plates 18. The first connecting plate 3 is slid along the guide plate 18 so that the end of the first connecting plate 3 is aligned with the end of the clamp 2. Then welding is performed to complete the welding and fixing of the first connecting plate 3.

[0075] The second connecting plate 6 is pressed tightly against another set of guide plates 18. The second connecting plate 6 is slid along the guide plates 18 so that the end of the second connecting plate 6 is aligned with the other end of the clamp 2. Then welding is performed to complete the welding and fixing of the second connecting plate 6.

[0076] S3: Weld reinforcing ribs 4 at the connection between the first connecting plate 3 and the clamp 2, and at the connection between the second connecting plate 6 and the clamp 2, respectively, to enhance strength and stability.

[0077] S4: Repeat steps S2 and S3 until all remaining clamp 2 welding work is completed.

[0078] In this embodiment, the bracket is self-made. The steel ring 13 can be quickly positioned and cut using a self-made positioning and cutting table. The positioning and cutting table has a first set screw 11. When the first set screw 11 is tightened, the ends of the first set screw 11 are located on the same circle. This ensures that the steel ring 13 is self-centered and clamped, and that the steel ring 13 is coaxially set with the positioning plate. This ensures that subsequent line drawing and cutting are accurate. The structure is simple, positioning is convenient, cutting and blanking are easy, and work efficiency can be improved.

[0079] The self-made welding auxiliary table has a limiting plate 15 and a second set screw 17. The second set screw 17 can be used to make the clamp 2 fit tightly against the limiting plate 15 and fix it. The welding auxiliary table also has a positioning clip to position the two ends of the clamp 2. It is also equipped with a guide plate 18 to make the first connecting plate 3 and the second connecting plate 6 aligned with the ends of the clamp 2, which is beneficial to the subsequent welding work. There is no need to perform alignment and other processes, which saves time and improves welding efficiency.
