• Tube Details: It includes a 48.3mm diameter socket tube, with thicknesses of 4.0mm (2.26 KG) or 3.2mm (2.19 KG), depending on the model.
• Functionality: Used for leveling feet at the Jack and supporting beams in slab formwork, compatible with other Cuplock components.

Survey Note: Detailed Analysis of Cuplock Scaffolding Jack Plate

Introduction

The Jack plate is a fundamental component of the Cuplock scaffolding system, which is widely used in construction, maintenance, and industrial projects for its versatility and safety. This survey note provides a comprehensive examination of the Jack plate, focusing on its properties, specifications, and role within the Cuplock system, based on detailed research from authoritative sources.

Background on Cuplock Scaffolding

Cuplock scaffolding is a modular system known for its node-point connection mechanism, allowing quick assembly and high load-bearing capacity. The jack plate, particularly the socket jack plate, is essential for providing stability to vertical standards, ensuring the structure can handle various loads while maintaining safety. It is typically used in conjunction with universal jacks for leveling and as part of formwork systems for slab and beam shoring.

Properties and Specifications

The following table summarizes the key properties and specifications of the Cuplock scaffolding jack plate, specifically the socket jack plate, as derived from manufacturer data and industry standards:

Comparison with Other Systems

To provide context, the Cuplock socket jack plate can be compared with similar components in other scaffolding systems, such as the Crab 60 system:

This comparison highlights the specific design of the Cuplock jack plate for its system, ensuring compatibility with universal jacks and other Cuplock components.

Functionality and Applications

The socket jack plate serves dual purposes within the Cuplock system:

• Leveling and Stability: At the base, it works with universal jacks to form adjustable scaffold jack jacks, allowing leveling on uneven ground. This is crucial for maintaining structural integrity and safety, especially in construction sites with varying terrain.
• Formwork Support: At the top of the Cuplock slab formwork system, it supports deck beams and infill beams, working alongside drop heads to facilitate concrete slab and beam shoring. This versatility makes it suitable for a range of applications, including building construction, industrial projects, and maintenance work.

The jack plate’s design, with a drilled socket for securing bolts, enhances stability by allowing tight connections when necessary, ensuring the scaffolding can withstand dynamic loads and environmental conditions.

Additional Types and Context

While the socket jack plate is the standard for Cuplock scaffolding, it is worth noting other types of jack plates mentioned in broader scaffolding contexts:

• Jack Plate with 16mm Solid Bar: Used for tube and clamp systems, with heights ranging from 50mm to 100mm.
• Jack Plate with 34mm-36mm or 32mm Small Tube: Designed for adjustable scaffolding props, offering flexibility in different scaffolding setups.
• Solid Adjustable Base Plate: Typically used for frame scaffold systems like Kwikstage, with threaded rod diameters from 26mm to 48mm, and can be adapted for Cuplock, though it is not the standard.

These alternatives are not specific to Cuplock but illustrate the diversity of jack plate designs across scaffolding systems. For Cuplock, the socket jack plate remains the primary choice, ensuring compatibility and efficiency.

Safety and Standards

The material of the jack plate, high-strength steel certified to EN 74 and EN 12810, underscores its compliance with international safety standards. These certifications ensure the jack plate can handle the required loads and resist corrosion, extending its lifespan and reducing maintenance needs. Galvanized or painted finishes further enhance durability, making it suitable for outdoor and harsh environments.

Manufacturer Insights

Wellmade, a leading manufacturer, provides detailed specifications for the Cuplock socket jack plate, emphasizing its role in both construction and formwork applications. Their products are tested for quality, with welding lines checked according to ISO certification, ensuring reliability. This aligns with the broader industry trend of prioritizing safety and efficiency in scaffolding systems.

Conclusion

The jack plate of Cuplock scaffolding, primarily the socket jack plate, is a vital component that ensures stability and support for vertical standards. With a 152mm x 152mm plate size, 10mm thickness, and a 48.3mm socket tube made of high-strength steel, it meets EN 74 and EN 12810 standards, offering durability and safety. Its dual functionality as a leveling foot and formwork support, combined with compatibility with universal jacks and other Cuplock components, makes it indispensable for construction projects. While other base plate types exist for different systems, the socket base plate is the standard for Cuplock, as evidenced by detailed manufacturer data and industry resources.
