Description

Technical Field

[0001] This utility model relates to the field of building wall construction technology, and in particular to a support rod structure for concrete wall pouring. Background Technology

[0002] In the field of concrete wall pouring, existing support rod structures mainly include steel pipe support rods and adjustable screw support rods. Steel pipe support rods are constructed by splicing multiple steel pipes together and fixing them with fasteners to form a stable frame to support the wall formwork. Adjustable screw support rods utilize the telescopic function of the screws to adjust the length according to the wall height and pouring requirements, providing convenient and quick support for the formwork. Steel pipe support rods use fasteners to fix the steel pipes into a specific shape, relying on the stability of the overall frame to withstand the lateral pressure during concrete pouring. Adjustable screw support rods extend or shorten by rotating the screws to tighten against the formwork. However, steel pipe support rods are cumbersome to assemble and disassemble, time-consuming and labor-intensive, and difficult to adjust the height precisely; adjustable screw support rods are prone to deformation and loosening of the screws under excessive lateral pressure, affecting the stability of the support and posing safety hazards.

[0003] In existing technologies, such as the support rod structure for concrete wall pouring (publication number CN221702802U), which relates to the field of building wall construction technology, the structure includes a support rod body and an arc-shaped support plate at its left end. The support rod body has anti-slip ribs on its side, and a positioning rod is located on the left side of the arc-shaped support plate. A positioning cone extends from the end of the positioning rod, and a spacer block is provided at the junction of the bottom of the support rod body and the side of the arc-shaped support plate. This support rod structure improves the connection stability between the support rod body and the insulation board, effectively limiting the distance between the insulation board, the concrete wall, and the reinforcing steel, preventing the reinforcing steel from getting too close to the insulation board, thus helping to ensure the insulation quality of the insulation board and improving the overall construction quality. It is also low-cost and highly practical. However, this design still has some drawbacks. It lacks a mechanism to buffer and disperse stress, and it also lacks an anti-friction device, requiring further improvement.

[0004] Therefore, this application provides a support rod structure for concrete wall casting to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a support rod structure for concrete wall pouring. The structure is simple and the support effect is good.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A support rod structure for concrete wall pouring includes a top plate, a first connecting block fixedly connected to the lower end of the top plate, second connecting blocks rotatably arranged on both sides of the first connecting block, a connecting rod fixedly arranged at the lower end of the two second connecting blocks, a support rod sleeved on the outer side of the lower end of the connecting rod, a universal ball fixedly arranged at the lower end of the support rod, and a base snapped onto the lower end of the universal ball.

[0008] Furthermore, a bottom anti-friction pad is fixedly connected to the lower end of the base.

[0009] Furthermore, a limit ring is fixedly connected to the upper end of the base.

[0010] Furthermore, tightening screws are threadedly connected to both sides of the limiting ring.

[0011] Furthermore, the upper end of the support rod and the lower end of the connecting rod are threaded with elastic sleeves.

[0012] Furthermore, a top anti-friction pad is fixedly provided at the upper end of the top plate.

[0013] Furthermore, the connecting rod is made of 40Cr alloy steel, and the support rod is made of Q345B carbon steel.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a support rod structure for concrete wall pouring, employing a universal ball joint connecting the base and the support rod. The universal ball joint allows the support rod to rotate flexibly and be finely adjusted in multiple directions, easily adapting to wall templates of different angles and shapes, greatly improving the convenience and accuracy of installation. Furthermore, during concrete pouring, when the template is subjected to uneven lateral pressure, the universal ball joint can buffer and disperse stress, reducing the risk of damage to the support rod due to uneven stress, enhancing the overall structural stability, ensuring the quality of wall pouring, and stably performing its supporting function under different construction environments.

[0016] 2. This utility model proposes a support rod structure for concrete wall pouring, featuring rubber toothed anti-friction pads at the bottom of the base and the top of the top plate. The rubber material itself possesses excellent elasticity and friction, and the toothed design further increases the engagement with the contact surface, effectively preventing slippage of the support rod under stress and improving support stability. Simultaneously, the rubber pads buffer the vibration and impact during concrete pouring, reducing stress concentration and wear on the base and top plate, thus extending the service life of the components. Furthermore, the toothed structure adapts to contact surfaces with varying flatness, enhancing the equipment's applicability in complex construction environments and ensuring the safety and stability of the wall pouring process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 3 One embodiment provided by this utility model:

[0025] A support rod structure for concrete wall pouring includes a top plate 1, a first connecting block 2 fixedly connected to the lower end of the top plate 1, second connecting blocks 3 rotatably arranged on both sides of the first connecting block 2, a connecting rod 4 fixedly arranged at the lower end of the two second connecting blocks 3, a support rod 6 sleeved on the outer side of the lower end of the connecting rod 4, a universal ball 11 fixedly arranged at the lower end of the support rod 6, and a base 7 snapped onto the lower end of the universal ball 11.

[0026] Specifically, the top plate 1 directly contacts the wall formwork, providing top support. The first connecting block 2 and the second connecting block 3 are rotatably connected, allowing the top plate 1 to rotate slightly, enhancing the adaptability of the support angle. Simultaneously, a disc spring (2mm thick, 50-80N spring force) is added to the rotation axis (12mm diameter) of the first connecting block 2 and the second connecting block 3, providing moderate damping (rotational torque 3-5N・m) to prevent rotation due to vibration during support. The connecting rod 4 has a diameter of 30mm±0.2mm, a length of 500mm±5mm, and is galvanized (8μm zinc layer thickness) for corrosion protection. The support rod 6 has an inner diameter of 32mm±0.2mm, is clearance-fitted with the connecting rod 4, has a length of 1000mm±10mm, and is coated with anti-rust paint (60μm dry film thickness). Connecting rod 4 and support rod 6 are fitted together to form the telescopic part of the support body. The universal ball joint 11 is made of bearing steel (GCr15), with a diameter of 50mm ± 1mm ​​and a rotation angle range of ±30° to meet multi-angle support requirements. Its surface is chrome-plated (0.05mm thick) to enhance wear resistance. The universal ball joint 11 is snapped onto the base 7 with a gap ≤ 0.1mm at the snap-fit ​​point, ensuring smooth rotation without looseness. This allows for multi-angle rotational connection between support rod 6 and base 7. Base 7 is made of cast iron (HT200), weighing ≥ 2kg, lowering the center of gravity. Its bottom area of ​​200mm × 200mm increases the load-bearing area, providing bottom support for the overall structure.

[0027] Reference Figure 3 The lower end of the base 7 is fixedly connected to a bottom anti-friction pad 12, and the upper end of the base 7 is fixedly connected to a limit ring 9. The limit ring 9 is threadedly connected to tightening screws 10 on both sides.

[0028] Specifically, the bottom anti-friction pad 12 is made of nitrile rubber, which is oil-resistant and aging-resistant, with a thickness of 5mm±0.5mm, a toothed structure (tooth pitch 8mm, tooth height 3mm), a static friction coefficient ≥0.8 (dry concrete surface), and a hardness of 60±5 Shore A, increasing the friction between the base 7 and the ground and preventing slippage; the limiting ring 9 surrounds the universal ball 11, and a rubber dustproof ring (diameter 60mm, cross-sectional diameter 3mm) is added to the upper opening to prevent concrete slurry and dust from entering the rotation gap of the universal ball 11 and avoiding jamming failure. By tightening the screw 10 to tighten the universal ball 11, its rotation angle can be fixed to prevent angular displacement due to force during support, thus enhancing structural stability.

[0029] Reference Figure 4 The upper end of the support rod 6 and the lower end of the connecting rod 4 are threadedly connected to a tensioning sleeve 5.

[0030] Specifically, the tensioning sleeve 5 is made of 45# steel (with a blackened surface treatment), with a length of 80mm ± 2mm, an internal thread of M30×1.5, and is threaded to the connecting rod 4 and the support rod 6. The thread accuracy is 6H, and the adjustment stroke is 300mm to meet the requirements for fine-tuning the height. Rotating the tensioning sleeve 5 can adjust the sleeve length of the connecting rod 4 and the support rod 6, thereby adjusting the overall support height. After adjustment, tightening the tensioning sleeve 5 can fix the relative position of the two and ensure the stability of the support length.

[0031] Reference Figure 2 A top anti-friction pad 8 is fixedly installed on the upper end of the top plate 1.

[0032] Specifically, the top anti-friction pad 8 is made of nitrile rubber, which is oil-resistant and aging-resistant, with a thickness of 5mm±0.5mm, a toothed structure (tooth pitch 8mm, tooth height 3mm), a static friction coefficient ≥0.8 (dry concrete surface), and a hardness of 60±5 Shore A. It fits the contact surface between the top plate 1 and the wall formwork, increases friction to prevent the top plate 1 from sliding relative to the formwork, and at the same time uses the elasticity of rubber to buffer the vibration during pouring, reducing the wear between the formwork and the top plate 1.

[0033] Reference Figure 1 , Figure 4 Connecting rod 4 is made of 40Cr alloy steel, and support rod 6 is made of Q345B carbon steel.

[0034] Specifically, 40Cr alloy steel has high strength, high toughness and good wear resistance, making it suitable for making connecting rod 4, and it can withstand large bending and tensile stresses; Q345B carbon steel has high strength, good plasticity and moderate cost, and can provide stable support force as support rod 6. The two work together to ensure the overall load-bearing capacity of the support structure.

[0035] Working principle: During use, adjust the sleeve length of the connecting rod 4 and the support rod 6 by rotating the tension sleeve 5 according to the height of the wall template. After determining the support height, tighten the tension sleeve 5 to fix it. Adjust the angle of the support rod 6 through the universal ball 11 so that the top anti-friction pad 8 of the top plate 1 is in contact with the template, and the bottom anti-friction pad 12 of the base 7 is in contact with the ground. Tighten the tightening screw 10 of the limiting ring 9 to fix the angle of the universal ball 11. During pouring, the force of the template is transmitted to the top plate 1, and then to the base 7 through the connecting rod 4 and the support rod 6. The universal ball 11 buffers and disperses the stress, the anti-friction pad prevents slippage, and the rotational cooperation of the first connecting block 2 and the second connecting block 3 further adapts to small angle changes, ensuring the stability of the support.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
