Types of Table Form Shuttering
Table Form Shuttering is a type of shuttering specialized in floor concreting and is widely used in high-rise buildings, multi-layer industrial factory buildings, substructures, etc.
Structure of Table Form Shuttering
Table Form Shuttering is designed with a simple structure, making it easy to assemble and disassemble and can be reused.
Materials Used in Table Form Shuttering
A variety of materials are used in the construction of concrete formwork, ranging from traditional materials like timber, steel, aluminum, and plywood to non-traditional materials like fiberglass. The systems used can be a combination of two materials, with wood products being the most commonly used material for formwork.
Advantages of Table Form Shuttering
Table Form Shuttering is a cost-effective solution for floor concreting, with its simple structure, easy assembly and disassembly, and reusability.
Types of Table Form Shuttering
1. Climbing Formwork System
Concrete wall formwork is a cost-effective solution for constructing walls and other vertical structures. This type of formwork is made up of a steel or timber frame, which is then filled with plywood, plastic or other materials that can be easily removed and replaced to create a strong and durable concrete wall. It is an ideal choice for those looking for a quick, efficient and cost-effective way to build walls. The formwork can also be reused multiple times, making it even more cost-effective.
2. Table Shifting Trolley: Streamlining Slab Construction
Table shifting trolleys are a special form of shifting equipment designed specifically for table formwork used in slab construction. This tool allows for the quick and easy shifting of table formwork, greatly speeding up the process of slab construction. One laborer and one trolley are all that are needed to shift each block of table formwork, dramatically increasing the speed of construction. The trolley is also self-propelled, allowing it to move up and down the slab with ease.
3. Crane Guided Climbing Formwork: An Efficient Solution
Crane guided climbing formwork is an efficient solution for constructing vertical walls and structures. This formwork is easily aligned and plumbed, and requires minimal crane time to lift and hook it onto the climbing cone cast into the concrete on the previous pour. This formwork system is also designed to be reused multiple times, making it an even more efficient solution for wall and structure construction.
Types of Table Form Shuttering
Table Form Shuttering is typically composed of four main components: an aluminum or timber scaffolding system, steel or timber channel beams, lifting brackets, and a plywood top surface. Let’s take a closer look at each of these components.
Aluminum/Timber Scaffolding System: The aluminum or timber scaffolding system consists of frames, jacks, and cross braces. This system provides the necessary support for the table form shuttering.
Channel Beams: Channel beams are used in the longitudinal direction for added support. They are usually made of steel or timber, and lifting brackets are fitted into them for the lifting of the shuttering by crane. Smaller length channel beams are also made from the same material.
Lifting Brackets: Lifting brackets are fitted into the channel beams. They are used to lift the shuttering by crane or other mechanical equipment.
Plywood Top Surface: The top surface of the shuttering is made of plywood. This provides a stable and even surface upon which the concrete can be placed.
Advantages of Table Form Shuttering
Increased Speed, Time Efficiency and Cost Economics: Table formwork systems provide a simple and safe tool for slab construction that significantly increases the speed, time efficiency, and cost economics on site. With minimal system components, the table system is easy to assemble, even by relatively unskilled labor. As no leg ties are required, areas below the soffit are kept clear to maximize safety. Additionally, the leg capacity of 35kN enables larger tables to be constructed, resulting in minimized construction cycle time and cost.
High Reusability and Low Waste: The table formwork system offers good sustainability due to its high reusability over multiple construction cycles with minimal waste. The simplicity of assembly and disassembly also results in large savings in time, effort, manpower, and labor costs.
Minimized Use of Cranes: The basic assembly of the table system can be handled manually, minimizing the use of crane time and allowing for quick and easy transportation and storage.
Improved Practicality Onsite:
The table system’s simple design makes it a preferred system of contractors for use in large scale developments. Interconnected truss members provide a stable working platform and the repetitive nature of work ensures quick familiarity with safety procedures. Falsework units can be assembled at ground level to reduce the risk of working at height. Decking with non-slip surfaces can also be used to enhance safety. The table formwork system can also include standard health and safety features such as guard rails.
