Description

Technical Field

[0001] This utility model relates to the technical field of steel cage processing equipment, and in particular to a jig for processing steel cages for large-diameter pile foundations. Background Technology

[0002] Existing rebar cage jigs mostly employ fixed welded structures, which suffer from low positioning accuracy, inconvenient assembly and disassembly, and poor adaptability. Furthermore, while many large-diameter pile foundation rebar cage jigs have adopted modular jigs, their connections rely on multiple levels of circular holes and insert rods, making assembly cumbersome. They also lack dedicated support structures for large-diameter rebar cages and cannot effectively resist radial displacement of the main reinforcement bars. Moreover, the separate design of the operating platform and the jig further complicates construction. Especially for large rebar cages with diameters exceeding 2.8m, traditional jigs struggle to ensure uniform spacing of the main reinforcement bars, welded joints are prone to deformation, and the concentricity deviation of the rebar cage is significant. Therefore, to meet the high-quality and high-efficiency construction requirements of building engineering, a high-precision, modular, and dedicated positioning jig suitable for large-diameter rebar cages is urgently needed. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a jig for processing large-diameter pile foundation steel cages. Through modular design, a precise positioning system, and an integrated operating platform, it enables efficient processing of large-diameter steel cages and improves their resistance to deformation and versatility.

[0004] To achieve the above objectives, the present invention adopts the following technical measures: a jig for processing large-diameter pile foundation steel cages, comprising multiple positioning jigs arranged side by side at equal intervals, each positioning jig comprising two long vertical support rods arranged at intervals, an arc-shaped transverse main beam installed between the two long vertical support rods, and the arc-shaped notch of the transverse main beam facing upward, and a plurality of positioning grooves provided on the inner side of the arc-shaped notch for fixing the main reinforcement of the steel cage;

[0005] On the same horizontal plane on the side away from the transverse main beam, there are accessible crossbeams, and guardrail posts are installed at the outer ends of the accessible crossbeams.

[0006] When multiple positioning frames are arranged side by side at equal intervals, steel planks are fully laid on the accessible beams on the same side of the transverse main beam, and guardrail horizontal bars are installed on the guardrail uprights on the same side of the transverse main beam. Prefabricated steel ladders are installed between the accessible beams near the outermost end and the ground.

[0007] Optionally, a diagonal reinforcing bar is installed between the long column of the vertical support rod of the jig located on the same side of the transverse main beam and the accessible crossbeam.

[0008] Furthermore, the lower ends of the inclined reinforcing rod and the long column of the vertical support rod of the jig located on the same side of the transverse main beam are both installed on the jig base plate, and a short column of the jig is also installed on the side of the jig base plate close to the transverse main beam to support the transverse main beam.

[0009] Furthermore, a longitudinal reinforcing plate and a transverse reinforcing plate are installed at the bottom of the arc of the transverse main beam.

[0010] Furthermore, the base plate of the jig and the transverse reinforcing plate in the middle of the main beam are located on the same horizontal plane.

[0011] Optionally, a longitudinal reinforcing plate at the bottom of the vertical support rod of the jig is installed between the long column and the base plate of the jig, and a transverse reinforcing plate at the bottom of the short column is installed between the short column and the base plate of the jig.

[0012] Furthermore, the oblique reinforcing rod is fixed at a 45° angle to the long column of the vertical support rod of the jig.

[0013] Preferably, the distance between two adjacent positioning frames is 2000mm.

[0014] Compared with the prior art, the present invention has the following advantages and effects:

[0015] (1) The operating platform and the frame are integrated into one, and the operating platform is equipped with guardrails, which improves construction safety;

[0016] (2) Through the arc-shaped transverse main beam and positioning groove, the processing accuracy is higher and it can effectively resist the radial displacement of the main reinforcement;

[0017] (3) Through the support rods, long columns, short columns and various reinforcing components, it can withstand the weight of large-diameter steel cages. Attached Figure Description

[0026] like Figure 1 As shown, the upper part of the vertical support rod 8 of the jig is bolted to the main beam support groove plate 7 on the opposite side. The end of the main beam support groove plate 7 is provided with an arc transition section, which is used to place the transverse main beam 1 so that the transverse main beam 1 and the main beam support groove plate 7 are smoothly connected.

[0027] In a preferred embodiment of this utility model, the transverse main beam 1, the long column 8 of the vertical support rod of the frame, the short column 9 of the frame, the accessible crossbeam 10, and the reinforcing components are all made of Q235B steel.

[0028] In a preferred embodiment of this utility model, the arc-shaped notch of the transverse main beam 1 is used to accommodate a steel cage with a diameter of Φ1.2m-3.0m.

[0029] In a preferred embodiment of this utility model, the oblique reinforcing rod 11 is welded and fixed to the long column 8 of the vertical support rod of the frame at a 45° angle.

[0032] The following is a reference to the appendix. Figure 1 Appendix Figure 2The implementation steps of the jig for processing steel cages for large-diameter pile foundations described in this utility model are explained in detail.

[0033] Step 1: Install the positioning frame

[0034] 1. Arrange the base plates 3 of the jig frame at a horizontal spacing of 1468mm and a vertical spacing of 2000mm, and fix them to the ground with M20 expansion bolts (torque ≥150N·m);

[0035] 2. Install the long vertical support rod 8 and the short vertical support rod 9 on the base plate 3 of the jig frame, with a verticality deviation of ≤2mm / m, and weld the longitudinal reinforcing plate 5 and the transverse reinforcing plate 6 at the bottom of the column in sequence.

[0036] 3. Install a main beam support groove plate 7 on the upper part of the side opposite to the long column 8 of the vertical support rod of the frame to support the transverse main beam 1.

[0037] 4. Install the transverse main beam 1, ensuring that the arc notch faces the inside of the reinforcing cage;

[0038] 5. Weld the transverse reinforcing plate 2 and the longitudinal reinforcing plate 4 at the transverse and longitudinal nodes in the middle of the transverse main beam 1, and perform full welding (weld height ≥ 10mm).

[0039] Step 2: Installation on a manned operating platform

[0040] 1. Adjust the height of the manned operating platform 10 to the design elevation and bolt it to the long column 8 of the vertical support rod of the jig frame;

[0041] 2. Install the diagonal reinforcing rod 11, adjust the angle between the diagonal reinforcing rod 11 and the long column 8 of the vertical support rod of the jig to 45°, and tighten the connecting bolts;

[0042] 3. Check the perpendicularity of the vertical support rod 8 of the jig and the horizontal main beam 1. The deviation should be ≤2mm / m.

[0043] Step 3: Installation of guardrails

[0044] 1. Fully cover the steel scaffolding planks 14 and the accessible crossbeams 10;

[0045] 2. A 1.5m high guardrail post 12 is welded to the end of the accessible beam 10, and guardrail crossbars 13 are welded to the guardrail post 12 at heights of 0.6m and 1.5m.

[0046] Step 4: Positioning and binding of main reinforcement bars

[0047] 1. Pass the main reinforcement bars (Φ28) through the positioning slots of the transverse main beam 1 in sequence. Each main reinforcement bar must pass through the corresponding positioning slot of all the jigs.

[0048] 2. Use tie wire to temporarily fix the main reinforcement bars and stirrups, ensuring that the stirrup spacing error is ≤ ±5mm;

[0049] 3. After binding, disassemble and remove the positioning frame for reuse.

[0050] Example parameters:

[0051] 1. Total height: 2.8m, plan dimensions: 10120mm × 824mm;

[0052] 2. Single piece weight: 327.5kg, 18 pieces per workshop, total weight 5.895t;

[0053] 3. Applicable steel cage diameter: 2.8m (adjustable range 1.2m-3.0m).

[0054] Precautions:

[0055] 1. Apply anti-rust grease to bolted connections to prevent rust from affecting disassembly;

[0056] 2. Regularly inspect the wear of the positioning groove; if the cumulative deviation is >2mm, the transverse main beam 1 needs to be replaced.

[0057] 3. The jig should be stored horizontally to prevent the I-beams from twisting or deforming.
