Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a one-time forming device for high-support rigid steel columns. Background Technology

[0002] A reinforced column is a structure composed of steel sections encased in concrete. It is also called a reinforced concrete column or a reinforced concrete column, and sometimes a steel-concrete column. Compared with concrete structures, it has many advantages. It is generally widely used in large structures to minimize the cross section, maximize the load-bearing capacity, and save space. Common types include H-beams, cross-shaped steel columns with concrete, and round steel columns with concrete.

[0003] Currently, traditional rigid structural components are composed of concrete, steel sections, longitudinal reinforcing bars, and stirrups. They have limited internal space, complicated and cumbersome work processes, and long construction cycles. Both rebar tying and formwork erection involve high-altitude operations, posing significant safety risks.

[0004] Therefore, it is necessary to provide a new one-time forming device for high-support rigid steel columns to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a one-time forming device for high-strength steel columns that increases the load-bearing capacity of steel columns, avoids the safety risks of high-altitude reinforcement binding and formwork operations, and improves construction efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a one-time forming device for high-support rigid steel columns, comprising: a steel column, wherein a base plate is welded and fixed to the bottom end of the steel column, a connecting plate is welded and fixed to the side wall of the top end of the steel column, and studs are welded and fixed to the side wall of the steel column; limiting ribs, wherein the limiting ribs are welded and fixed to the center position of the four sides of the steel column; a formwork structure, wherein the formwork structure is installed on the periphery of the steel column, the formwork structure includes a bottom template, side templates, edges, a top plate, and grouting holes, wherein the bottom template is supported on the ground by pads, and the steel column is supported on the surface of the bottom template by the limiting ribs, the edges are fixed to the top and bottom ends of the side templates, the side templates are opened outward and supported on the edge of the bottom template by the edges, the top plate is supported on the top surface of the side templates by the edges, and the grouting holes are located inside the top plate; an end plate, wherein the end plate seals the openings at both ends of the formwork structure; and a reinforcing structure, wherein the reinforcing structure is installed on the outer side wall of the formwork structure.

[0007] Preferably, the welding lengths of the limiting ribs are all consistent, and the length of the limiting ribs is greater than the length of the studs, and the side of the steel column abuts against the inner wall of the side formwork through the limiting ribs.

[0008] Preferably, the side template is bolted to the bottom template and the top plate respectively through the edges, and the side template, the bottom template and the top plate are combined to form a square.

[0009] Preferably, a reinforcing rib is welded and fixed between the base plate and the steel column, and the side wall of the base plate is also provided with screw holes.

[0010] Preferably, the reinforcing structure includes side strips, tie rods, and horizontal strips. The side strips abut against the side walls of the side template, and the horizontal strips abut against the side walls of the top plate and the bottom template, respectively. The tie rods pass through the horizontal strips and are connected to one end of the side strips.

[0011] Preferably, the length of the horizontal strip is the same as the width of the top plate and the bottom template, and the two ends of the horizontal strip abut against the side wall of one end of the side strip.

[0012] Preferably, the end plate foam board is divided into multiple pieces, which are glued together with adhesive tape, and a rectangular opening is formed in the middle to match the steel column.

[0013] Compared with related technologies, the one-time forming device for high-support rigid steel columns provided by this utility model has the following beneficial effects:

[0014] This utility model provides a one-time forming device for high-strength steel columns with high formwork support. First, the limiting ribs, studs, connecting plates, and base plates are welded to corresponding positions on the sidewalls of the steel column. This allows the limiting ribs to support the position of the steel column. When erecting the formwork structure, the limiting ribs restrict the position of the formwork structure, ensuring that the spacing between each surface of the formwork structure and the steel column is consistent under the support of the limiting ribs. This guarantees the center position of the steel column within the formwork structure and also ensures that the thickness of the concrete protective layer on the four outer surfaces is consistent during subsequent concrete pouring, thereby enabling the steel column to achieve maximum load-bearing capacity. Then, the end plates connect the two ends of the formwork structure... The formwork is sealed to prevent leakage from both ends during later concrete pouring. The reinforcing structure is attached to the perimeter of the formwork, enhancing its stability and preventing deformation or bulging due to excessive concrete pressure. Grouting holes on the bottom of the formwork allow for concrete pouring into the steel column, and the amount of grout injected can be observed through adjacent holes. When grout is flowing from all holes, the formwork is fully filled with concrete. After the concrete has completely solidified, the formwork can be removed for use. This device increases the load-bearing capacity of the steel column, avoids the safety risks of high-altitude reinforcement and formwork operations, and improves construction efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 , Figure 1 A schematic diagram of a preferred embodiment of the high-support rigid steel column one-time forming device provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the overall cross-section shown; Figure 3 for Figure 1 The diagram shows the overall side view of the structure. Figure 4 for Figure 2The diagram shows a three-dimensional view of the steel column structure. The high-support, rigid steel column one-time forming device includes: a steel column 1, with a base plate 7 welded to its bottom end, a connecting plate 3 welded to the side wall of the top of the steel column 1, and studs 2 welded to the side wall of the steel column 1; limiting ribs 9, welded and fixed to the center positions of the four sides of the steel column 1; and a formwork structure 4, installed around the steel column 1, comprising a bottom template 41, side templates 42, edges 43, a top plate 44, and grouting holes 45. The bottom template 41... The pad block 6 is erected on the ground, and the steel column 1 is erected on the surface of the bottom template 41 through the limiting rib 9. The edge 43 is fixed to the top and bottom of the side template 42. The side template 42 is erected on the edge of the bottom template 41 with the opening facing outward through the edge 43. The top plate 44 is supported on the top surface of the side template 42 through the edge 43. The grouting hole is located inside the top plate 44. The end plate 8 is used to seal the openings at both ends of the formwork structure 4. The reinforcing structure 5 is installed on the outer wall of the formwork structure 4.

[0022] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the welding lengths of the limiting ribs 9 are all consistent, and the length of the limiting ribs 9 is greater than the length of the studs 2. The side of the steel column 1 abuts against the inner wall of the side formwork 42 through the limiting ribs 9. The side formwork 42 is bolted to the bottom formwork 41 and the top plate 44 through the edges 43, and the side formwork 42, the bottom formwork 41 and the top plate 44 are combined to form a square. This facilitates the support of the steel column 1 by the limiting ribs 9, so that the distance between the steel column 1 and the bottom formwork 41, the side formwork 42 and the top plate 44 is equal under the support of the limiting ribs 9. This helps to limit the distance between the formwork and the steel column 1, thereby ensuring that the steel column 1 is in the center position of the later concrete pouring.

[0023] In the specific implementation process, such as Figure 2 and Figure 4 As shown, a reinforcing rib is welded and fixed between the base plate 7 and the steel column 1, and the side wall of the base plate 7 is also provided with screw holes; this facilitates the bolting of the steel column 1 through the base plate 7 during later use.

[0024] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3As shown, the reinforcing structure 5 includes side strips 51, tie rods 52, and horizontal strips 53. The side strips 51 abut against the side wall of the side template 42, and the horizontal strips 53 abut against the side walls of the top plate 44 and the bottom template 41, respectively. The tie rods 52 pass through the horizontal strips 53 and connect to one end of the side strips 51. The length of the horizontal strips 53 is the same as the width of the top plate 44 and the bottom template 41, and both ends of the horizontal strips 53 abut against the side wall of one end of the side strips 51, so that the horizontal strips 53 and the side strips 51 can surround the periphery of the formwork structure 4, thereby further strengthening the stability of the formwork structure 4.

[0025] In the specific implementation process, such as Figure 2 As shown, the end plate 8 is made of foam board divided into multiple pieces, which are glued together with tape and form a rectangular opening in the middle to match the steel column 1 to prevent grout leakage.

[0026] The working principle of the high-support rigid steel column one-time forming device provided by this utility model is as follows:

[0027] In use, firstly, the corresponding length of the limiting ribs 9 are welded to the center of the four sides at both ends of the steel column 1, so that the limiting ribs 9 support the steel column 1. Then, the corresponding studs 2 and connecting plates 3 are welded. Next, the base plate 7 is welded to the bottom end of the steel column 1, and reinforcing ribs are welded to strengthen the fixing force of the base plate 7. Then, the bottom template 41 is erected and supported by the pad blocks 6, so that the bottom template 41 is on the ground. The side template 42 is installed at one edge of the bottom template 41 with bolts. Then, the welded steel column is hoisted onto the bottom template 41 by a crane. The position of the steel column 1 is adjusted so that the side wall of the steel column 1 abuts against the edge of the side template 42 through the limiting ribs 9, so that the position of the steel column 1 is restricted. Then, the other side template 42 is fixed to the edge of the other end of the bottom template 41 with bolts, thus enclosing the steel column 1 inside. Then, the top plate 44 is fixed to the top surface of the side formwork 42 with bolts, so that the side formwork 42, the bottom formwork 41 and the top plate 44 initially surround the steel column 1. Then, the end plate 8 is sealed at the openings at both ends of the formwork to seal the steel column 1 where concrete needs to be poured. Then, the side strips 51 and the horizontal strips 53 are used in conjunction with the tie rods 52 to clamp the outside of the formwork, so that the fixing of the side strips 51 and the horizontal strips 53 further strengthens the stability of the formwork. Then, grouting is injected into the inside through the grouting holes 45 provided on the side wall of the top plate 44. Then, the internal concrete pouring situation can be observed through the adjacent grouting holes 45. After the concrete is completely solidified, the formwork can be removed and used. This device has the advantages of increasing the load-bearing capacity of the steel column 1, avoiding the safety risks of high-altitude reinforcement binding and formwork operation, and improving construction efficiency.

[0028] Compared with related technologies, the one-time forming device for high-support rigid steel columns provided by this utility model has the following beneficial effects:

[0029] This utility model provides a one-time forming device for high-strength steel columns with high formwork support. First, the limiting ribs 9, the studs 2, the connecting plates 3, and the base plate 7 are welded to corresponding positions on the sidewalls of the steel column 1. This allows the limiting ribs 9 to support the position of the steel column 1. When the formwork structure 4 is erected on the steel column 1, the limiting ribs 9 restrict the position of the formwork structure 4, ensuring that each surface of the formwork structure 4 maintains a consistent distance from the steel column 1. This guarantees the center position of the steel column 1 within the formwork structure 4 and ensures that the thickness of the concrete protective layer on the four outer surfaces is consistent during subsequent concrete pouring. This allows the steel column 1 to achieve maximum load-bearing capacity. Then, the end plates 8 connect the two sides of the formwork structure 4... The ends are sealed to prevent leakage from both ends during later concrete pouring. The reinforcing structure 5 is clamped around the perimeter of the formwork structure 4 to enhance its stability, thereby preventing deformation or bulging due to excessive concrete pressure. The grouting holes 45 on the bottom of the formwork structure 4 allow concrete to be poured into the steel column 1. The amount of grout can also be observed through adjacent grouting holes 45. When grout is flowing from all grouting holes 45, the interior of the formwork structure 4 is filled with concrete. After the concrete has completely solidified, the formwork can be removed for use. This device increases the load-bearing capacity of the steel column 1, avoids the safety risks of high-altitude reinforcement and formwork operations, and improves construction efficiency.
