What Are the Key Components of Aluminium Formwork & Their Functions?
Introduction
Aluminium formwork has transformed the construction industry by offering a faster, more efficient, and cost-effective solution for building structures. Unlike traditional formwork made of timber or steel, aluminium formwork provides a lightweight, durable, and reusable option that ensures precision and quality in construction. To fully understand how this system works, it is essential to explore its key components and their functions.
This blog provides a comprehensive breakdown of aluminium formwork components, their roles, and how they contribute to modern construction practices.
1. Wall Panels
Function:
Wall panels form the vertical structure of the building by acting as a mold for concrete walls. These panels are lightweight yet strong, ensuring stability while withstanding high concrete pressure.
Key Features:
Made from high-strength aluminium alloy
Smooth surface for better concrete finish
Reusable for multiple projects
2. Slab Panels
Function:
Slab panels provide the base for casting horizontal floor slabs. These panels support the wet concrete until it hardens into a rigid structure.
Key Features:
Designed to carry the weight of freshly poured concrete
Interconnected with beam components for uniformity
Contributes to flat and even floor surfaces
3. Beam Formwork
Function:
Beam formwork consists of beam side panels and beam bottom panels that shape and support horizontal beams within a structure.
Key Features:
Supports load-bearing beams in high-rise buildings
Prevents concrete leakage by ensuring a tight fit
Ensures structural integrity of beams
4. Deck Panels
Function:
Deck panels are placed on top of beam formwork to create a supporting surface for slabs. These panels hold and shape the wet concrete poured for the slab.
Key Features:
Helps in achieving a monolithic structure
Lightweight yet strong, ensuring easy handling
Provides a smooth slab finish
5. Prop Heads / Drop Heads
Function:
Prop heads, also known as drop heads, support deck and slab panels during construction. They allow early removal of formwork while keeping the slab structure intact.
Key Features:
Supports deck and slab panels securely
Allows early striking of formwork to speed up construction
Adjustable height for flexibility in different projects
6. Wedge Pins & Tie Rods
Function:
These components ensure tight fitting and alignment of formwork panels. Tie rods hold the opposite panels together, preventing any bulging due to concrete pressure.
Key Features:
Wedge pins lock the formwork panels securely in place
Tie rods ensure stability by counteracting the force of wet concrete
Easy to install and remove, increasing work efficiency
7. Kickers / Starter Panels
Function:
Kick panels, or starter panels, act as the base for vertical formwork. They help in aligning and securing the initial layers of wall panels.
Key Features:
Ensures proper alignment of wall formwork
Provides a strong foundation for walls
Helps in precise concrete pouring
8. Internal & External Corner Panels
Function:
Corner panels are designed to join two perpendicular wall panels, ensuring that corners are properly shaped and reinforced.
Key Features:
Internal corner panels are used inside rooms
External corner panels connect outer walls
Ensures a seamless joint, preventing concrete leakage
9. Wall Ties / Tie Bars
Function:
Wall ties help maintain the correct spacing between opposite wall panels, ensuring structural stability.
Key Features:
Holds formwork firmly in position
Prevents misalignment due to concrete pressure
Ensures uniform wall thickness
10. Striking / Lifting Handles
Function:
These handles assist in the removal and repositioning of aluminium formwork after the concrete has set.
Key Features:
Helps in fast removal of formwork
Reduces labor efforts and time
Minimizes damage to formwork during dismantling
11. Brackets and Scaffold Bracing
Function:
These components provide temporary support to the formwork system, especially at elevated sections.
Key Features:
Ensures worker safety during construction
Helps maintain formwork alignment
Reduces risk of collapse due to improper support
12. Soffit Panels & Soffit Bolts
Function:
Soffit panels create a base for slab construction, while soffit bolts keep these panels in place.
Key Features:
Supports slab formwork before concrete hardens
Soffit bolts allow for quick and easy assembly
Enhances structural stability
