Description

Technical Field

[0001] The present application relates to the technical field of construction equipment, and in particular to a welding positioning device for main reinforcement bars of a steel cage. Background Art

[0002] In practice, most foundation treatments utilize a group-based reinforcement model, with cast-in-place piles being the most common type. A cast-in-place pile is a bored hole, then filled with concrete or reinforced concrete. The reinforced cage serves as the primary support structure for the pile, enhancing its strength and compressive resistance. Densely distributed within the pile, the cage restrains the concrete, enhancing the pile's overall strength and stability. This significantly increases the pile's bearing capacity, enabling it to withstand greater compressive and tensile forces.

[0003] However, the cast-in-place pile reinforcement cage is a cylindrical structure, with multiple main bars arranged in a circular pattern around the cage's sidewalls. The axial direction of each main bar is parallel to the cage's axis. If each main bar is not positioned properly during cage welding, some of the main bars may wobble or shift, causing the welded cage structure to deform and even fail due to significant deformation. Therefore, this application proposes a reinforcement cage main bar welding positioning device that can support and position each main bar distributed along the cylindrical sidewalls, preventing deformation of the cage caused by main bar wobble or shifting during welding. Utility Model Content

[0029] Figure 1 An embodiment of the present invention is shown, referring to Figure 1 In this embodiment, the main reinforcement welding positioning device of the steel cage includes: at least two supporting mechanisms, and a limiting mechanism respectively connected to each supporting mechanism.

[0030] Among them, see Figure 1The support mechanism includes a first support plate 1 and a second support plate 2 that are arranged upright and stacked up and down. The first support plate 1 is provided with an outer arc surface 11 on the side away from the second support plate 2, and the second support plate 2 is provided with an inner arc surface 21 on the side close to the first support plate 1. The outer arc surface 11 and the inner arc surface 21 are coaxial, and at least one first clamping groove 12 and at least one second clamping groove 22 are arranged along their respective circumferential directions; the limiting mechanism includes at least one connecting rod 3, each connecting rod 3 is connected to each second support plate 2. When welding the steel cage, first, each connecting rod 3 is vertically connected to each second support plate 2, then half of the main bars of the steel cage are arranged in each second clamping groove 22 at the corresponding position, then each first support plate 1 is connected to each second support plate 2, and finally, the other half of the main bars of the steel cage are arranged in each first clamping groove 12 at the corresponding position, so that each main bar is arranged in a circular manner, and each main bar is supported and limited to prevent the main bars from shaking or shifting during the welding process of the steel cage, resulting in deformation of the final welded steel cage.

[0031] Further, see Figure 2 The first support plate 1 is located at both ends of the outer arc surface 11 in the circumferential direction, and a first connecting ear 13 is provided at each end of the second support plate 2 is located at the inner arc surface 21 in the circumferential direction. Each first connecting ear 13 is connected to each second connecting ear 23 by a bolt, so that the outer arc surface 11 and the inner arc surface 21 are butt-jointed together.

[0032] Optionally, after the outer arc surface 11 and the inner arc surface 21 are connected, the distance from the center of each first slot 12 or each second slot 22 to the axis of the outer arc surface 11 or the inner arc surface 21 is consistent, so that each main rib is combined to form a standard cylindrical structure.

[0033] Optionally, the first support plate 1 is a crescent-shaped structure to reduce the weight of the first support plate 1 .

[0034] For example, (1) when welding a φ1000 steel cage, the radius of the outer arc surface 11 is set to 550 mm, the radius of the inner arc surface 21 is 450 mm, and the distance from the center of each first slot 12 to the axis of the outer arc surface 11, as well as the distance from the center of each second slot 22 to the axis of the inner arc surface 21, are both 500 mm; (2) when welding a φ1200 steel cage, the radius of the outer arc surface 11 is set to 650 mm, the radius of the inner arc surface 21 is 550 mm; the distance from the center of each first slot 12 to the axis of the outer arc surface 11, as well as the distance from the center of each second slot 22 to the axis of the inner arc surface 21, are both 600 mm;

[0035] Further, see Figure 3 The connecting rod 3 vertically passes through each second support plate 2, and a socket 31 is set on both sides of the connecting rod 3 on each second support plate 2. Each socket 31 is movably connected to a pin 32 to limit each second support plate 2.

[0036] Further, see Figure 3 The cross-section of the connecting rod 3 in the length direction is non-circular, and each support plate is provided with at least one through hole 24 that is interference fit with the cross-section of the connecting rod 3 in the length direction to prevent the second support plate 2 from rotating or deflecting around the length direction of the connecting rod 3, resulting in the position mismatch of the first card slot 12 or the second card slot 22.

[0037] Optionally, two connecting rods 3 are provided, which are respectively located on both sides of the axial direction of the inner arc surface 21, and a through hole 24 is provided on each side of the axial direction of the inner arc surface 21 of the second support plate 2. The two connecting rods 3 are arranged in parallel and respectively pass through each second support plate 2. A pin 32 is provided in each socket 31 so that each inner arc surface 21 is coaxial and the position of each second slot 22 of each second support plate 2 corresponds.

[0038] For example, the connecting rod 3 is a square tube with a wall thickness of 3mm and a length and width of 50mm×50mm. The thickness of the second support plate 2 is 20mm, and the length and width of the through hole 24 are 52mm×52mm. The connecting rod 3 is provided with two sockets 31 with a diameter of 12mm corresponding to each second support plate 2. The distance between the two sockets 31 is 32mm, and the pin 32 is a bolt with a specification of M10×1.5 (pitch of 1.5mm, bolt diameter of 10mm).

[0039] Further, see Figure 4 The support mechanism also includes a base plate 4 and a stiffening plate 5. The second support plate 2 is vertically connected to a base plate 4 on the side away from the first support plate 1. At least one stiffening plate 5 is provided between the first support plate 1 and the base plate 4 to make the first support plate 1 upright.

[0040] Optionally, two stiffening plates 5 are respectively provided at two included angles between the second support plate 2 and the bottom plate 4, so that the second support plate 2 can stand more stably on the ground.

[0041] In this embodiment, the best embodiment is to set up three supporting mechanisms and two connecting rods 3. Before welding the steel cage, first, the two connecting rods 3 are vertically passed through the three second support plates 2, and each socket 31 is installed with a pin 32 to limit the position of the three second support plates 2, so that the second slots 22 of the three second support plates 2 correspond to each other. Secondly, half of the main bars are respectively inserted into each second slot 22 at the corresponding position. Thirdly, the three first support plates 1 are respectively connected to the three second support plates 2 and fixed by bolts. Finally, the other half of the main bars are respectively inserted into each first slot 12 at the corresponding position. In this way, the main bars are arranged in a circular manner, and each main bar is supported and limited, preventing the main bars from shaking or shifting during the welding process of the steel cage, which may cause deformation of the final welded steel cage.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the present application. The dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
