Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a tool for controlling the spacing of axial reinforcement bars in a steel cage. Background Technology

[0002] A steel reinforcement cage is an important steel reinforcement assembly component in civil engineering. It is usually composed of axial bars, spiral or ring stirrups, and reinforcing hoops, which are connected by welding or binding. It has a cylindrical or square cage-like structure. Its core function is to provide skeletal support for the concrete structure, enhance the tensile, compressive, and shear resistance of the structure, and ensure the overall stability and durability of the project. When welding the axial bars, they need to be welded at equal intervals to ensure the stability of the structure. A clamping tool is used to control the spacing of each axial bar. The U-shaped opening at the front end of the tool is clamped onto the first axial bar. Then, the second axial bar is placed at the rear end of the stop bar on the tool. The distance between the U-shaped opening and the stop bar is the spacing between the two axial bars. The spacing between the two axial bars can be controlled. Then, the tool is lifted to raise the second axial bar close to the stirrup for welding, thus completing the welding and assembly of the steel reinforcement cage.

[0003] Traditional axial reinforcement spacing control tools often employ rigid frames. These tools have a fixed spacing determined during the manufacturing stage, making them unsuitable for the diverse needs of different engineering designs. For example, different pile depths may require different axial reinforcement spacings, and welded tools would require the fabrication of multiple sets of tools with varying spacings, resulting in resource waste. Therefore, a new tool for controlling the axial reinforcement spacing of steel cages is needed to address these issues.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a tool for controlling the spacing of axial bars in a steel cage, thereby solving the problem that many existing tools for controlling the spacing of axial bars use rigid frames, which are not convenient for adjusting the spacing.

[0006] The technical solution adopted by this application to solve its technical problem is: a tool for controlling the spacing of axial bars in a steel cage, including stirrups, a first axial bar and a second axial bar. The first axial bar and the second axial bar are fixed to the outer wall of the stirrup by welding at equal intervals.

The U-shaped opening formed by the second stop and the front end of the lifting rod is adapted to be engaged with the outer wall of the first axial rib and adapted to limit the lifting rod. The second axial rib is engaged with the rear end of the first stop. When the lifting rod is raised, the second axial rib can be raised close to the stirrup for equidistant welding.

[0009] Furthermore, a first arc-shaped plate is fixed to the rear end of the first stop bar, and a second arc-shaped plate is fixed to the lower end of the second stop bar. The first arc-shaped plate and the second arc-shaped plate are respectively attached to the first axial rib and the second axial rib, which is suitable for preventing the first axial rib and the second axial rib from slipping off.

[0010] Furthermore, an arc-shaped rubber plate is fixed to one side of both the first arc-shaped plate and the second arc-shaped plate.

[0011] Furthermore, a flat knob is threaded onto the front end of the first adjusting sleeve, and one side of the flat knob passes through the first adjusting sleeve and fits against the lifting rod, which is suitable for adjusting and installing the first adjusting sleeve.

[0012] Furthermore, a circular knob is threaded onto the rear end of the second adjusting sleeve. The lower end of the circular knob passes through the second adjusting sleeve and fits against the vertical rod, which is suitable for adjusting and installing the second adjusting sleeve.

[0013] Furthermore, a scale is provided on one side of the lifting rod.

[0014] Furthermore, a handle is fixed to the rear end of the lifting rod, and a rubber sleeve is fitted on the outer wall of the handle.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1-5As shown, this application provides a tool for controlling the spacing of axial bars in a steel cage, including a stirrup 1, a first axial bar 2, and a second axial bar 3. The first axial bar 2 and the second axial bar 3 are fixed to the outer wall of the stirrup 1 by welding at equal intervals. It also includes a lifting rod 4, a first adjusting sleeve 5, and a vertical rod 7. A first stop rod 6 is fixed to the upper end of the first adjusting sleeve 5, and the vertical rod 7 is fixed to the front end of the lifting rod 4. The first adjusting sleeve 5 is sleeved on the outer wall of the lifting rod 4 and is suitable for adjusting the spacing between the first stop rod 6 and the vertical rod 7.

[0028] A limiting component is installed at the upper end of the vertical rod 7 and is suitable for limiting the lifting rod 4.

[0029] Among them, stirrup 1 is usually designed in a ring shape to fit tightly against the overall structure of the reinforcing cage. Its cross-section can be circular, square, or other polygonal, depending on the engineering design and construction requirements. It is generally made of high-strength steel to ensure sufficient load-bearing capacity and durability. As the basic support structure of the reinforcing cage, stirrup 1 not only provides fixing points for the axial reinforcement but also enhances the overall stability of the reinforcing cage through its ring or spiral structure. The first axial reinforcement 2 and the second axial reinforcement 3 are usually long strips with a circular or square cross-section and a smooth surface or slight ribs to increase the bond strength with concrete. They are also made of high-strength steel to meet the structural load-bearing requirements. The reinforcing bars are evenly distributed on the outer wall of the stirrups 1 and are tightly connected to the stirrups 1 by welding to form the skeleton of the reinforcing cage. The lifting rod 4 is a long straight rod with a circular cross-section. Its length is determined according to the size of the reinforcing cage and construction requirements. It is generally made of lightweight and high-strength materials, such as aluminum alloy or carbon fiber composite materials, to reduce the burden on operators. The first adjusting sleeve 5 is a hollow cylinder that is fitted on the outer wall of the lifting rod 4 and can slide along the lifting rod 4 to adjust its position. The first stop rod 6 is a straight rod that is fixed at the upper end of the first adjusting sleeve 5 and is perpendicular to the lifting rod 4. By adjusting the position of the first adjusting sleeve 5, the distance between the first stop rod 6 and the vertical rod 7 can be changed, thereby controlling the welding spacing of the axial reinforcing bars.

[0030] like Figure 2 As shown, the limiting component includes a second adjusting sleeve 8 sleeved on the outer wall of the vertical rod 7. A second stop 9 is fixed at the front end of the second adjusting sleeve 8. The U-shaped opening formed by the second stop 9 and the front end of the lifting rod 4 is suitable for engaging with the outer wall of the first axial rib 2 and for limiting the lifting rod 4. The second axial rib 3 is engaged with the rear end of the first stop 6. When the lifting rod 4 is raised, the second axial rib 3 can be raised close to the stirrup 1 for equidistant welding.

[0031] The vertical rod 7 is a straight rod fixed to the front end of the lifting rod 4. The second adjusting sleeve 8 is a hollow cylinder fitted onto the outer wall of the vertical rod 7. The second stop rod 9 is a straight rod fixed to the front end of the second adjusting sleeve 8, forming a U-shaped opening with the front end of the lifting rod 4. It is made of wear-resistant and corrosion-resistant metal material. By adjusting the position of the second adjusting sleeve 8, it is ensured that the U-shaped opening can be accurately engaged with the welded axial rib, limiting the lifting rod 4 and thus ensuring the accuracy of the axial rib welding.

[0032] like Figure 3 As shown, a first arc plate 12 is fixed to the rear end of the first stop 6, and a second arc plate 13 is fixed to the lower end of the second stop 9. The first arc plate 12 and the second arc plate 13 are respectively attached to the first axial rib 2 and the second axial rib 3, which is suitable for preventing the first axial rib 2 and the second axial rib 3 from slipping.

[0033] The first arc-shaped plate 12 and the second arc-shaped plate 13 are both arc-shaped plate structures, which are fixed on the first stop 6 and the second stop 9 respectively. The arc-shaped plates are made of metal materials and fit in close contact with the axial ribs to prevent the axial ribs from slipping during the lifting process.

[0034] like Figure 4 As shown, an arc-shaped rubber plate 14 is fixed to one side of both the first arc-shaped plate 12 and the second arc-shaped plate 13;

[0035] Among them, the arc-shaped rubber plate 14 is made of wear-resistant and aging-resistant rubber material, which can increase the friction between it and the axial ribs and further improve the anti-slip effect.

[0036] like Figure 4 As shown, a flat knob 10 is threaded onto the front end of the first adjusting sleeve 5. One side of the flat knob 10 passes through the first adjusting sleeve 5 and fits against the lifting rod 4, which is suitable for adjusting and installing the first adjusting sleeve 5.

[0037] Rotating the flat knob 10 causes its lower end to move down close to the lifting rod 4. The friction between the flat knob 10 and the lifting rod 4 can limit the position of the first adjusting sleeve 5.

[0038] like Figure 4 As shown, a circular knob 11 is threaded onto the rear end of the second adjusting sleeve 8. The lower end of the circular knob 11 passes through the second adjusting sleeve 8 and fits against the vertical rod 7, which is suitable for adjusting and installing the second adjusting sleeve 8.

[0039] Rotating the circular knob 11 causes its lower end to move down close to the vertical rod 7. The friction between the circular knob 11 and the vertical rod 7 limits the position of the second adjusting sleeve 8. The surface of the circular knob 11 is provided with anti-slip texture for easy operation.

[0040] like Figure 4As shown, a scale 15 is provided on one side of the lifting rod 4;

[0041] The scale 15 is located on one side of the lifting lever 4 to visually display the spacing size, making it convenient for operators to make quick adjustments.

[0042] like Figure 4 As shown, a handle 16 is fixed to the rear end of the lifting rod 4, and a rubber sleeve 17 is fitted on the outer wall of the handle 16.

[0043] The handle 16 is long and narrow with a circular cross-section. A rubber sleeve 17 is fitted on the surface to improve grip comfort. The handle 16 and the rubber sleeve 17 are made of lightweight high-strength material and wear-resistant rubber material, respectively. The handle 16 is used by the operator to hold and lift the lifting rod 4 for welding operations.

[0044] Working principle: First, according to the design requirements, the position of the first adjusting sleeve 5 on the lifting rod 4 is adjusted to determine the distance between the first stop rod 6 and the vertical rod 7. This distance is the standard distance between the adjacent axial ribs to be welded. After the adjustment is completed, the position of the first adjusting sleeve 5 is fixed by using the flat knob 10.

[0045] Simultaneously, by adjusting the position of the second adjusting sleeve 8 on the vertical rod 7, it is ensured that the U-shaped opening formed by the second stop rod 9 and the front end of the lifting rod 4 can accurately engage with the welded first axial rib 2. After adjustment, the position of the second adjusting sleeve 8 is fixed using the circular knob 11.

[0046] The U-shaped opening of the tool is engaged with the outer wall of the first axial rib 2. At this time, the second stop 9 is in contact with the first axial rib 2. Through the cooperation of the second arc plate 13 and the arc rubber plate 14, the tool is ensured to be stable and will not slip.

[0047] The second axial rib 3 to be welded is placed at the rear end of the first stop 6, and the second axial rib 3 is prevented from slipping off by the cooperation of the first arc plate 12 and the arc rubber plate 14.

[0048] The operator holds handle 16 and lifts the lifting rod 4 to raise the second axial reinforcement 3 and bring it close to the outer wall of the stirrup 1. At this time, the distance between the second axial reinforcement 3 and the first axial reinforcement 2 is maintained at the preset standard distance.

[0049] After confirming the accurate position, welding is performed to weld and fix the second axial reinforcement 3 to the stirrup 1.

[0050] After completing the welding of one axial reinforcement bar, release handle 16 and remove the tool from the welded axial reinforcement bar. Repeat the above steps to continue welding the next axial reinforcement bar until the welding of all axial reinforcement bars in the entire steel cage is completed.

[0051] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
