A panel formwork system consists of more than the panels themselves. Different panel formwork components work together to connect panels, form corners, support alignment and assist with handling on site.
For the overall system, see What Is a Panel Formwork System?.
What Does a Panel Lock Do?
A panel lock connects adjacent panels and helps the panel line work as one system. Correct component compatibility is important because lock geometry and connection dimensions can vary between system families.
What Is a Corner Connection?
Corner components help form internal or external changes in direc..
Panel formwork is a modular formwork system used for reinforced-concrete walls, columns, foundations and retaining walls. Steel-framed panels work together with locks, corner connections, braces and lifting accessories to create a reusable and organized concrete-forming surface.
For current product options, see the Panel Formwork - Trio Formwork product page.
How Does Panel Formwork Work?
Prefabricated modular panels are connected side by side or vertically to form the required wall or column geometry. Locks secure panel joints, corner components complete changes in direction, braces support..
Trio panel formwork and H20 timber-beam formwork can both be used for reinforced-concrete walls and columns, but they differ in panel construction and the way they adapt to project dimensions. Panel systems rely on ready-made steel-framed modular panels, while H20 systems combine timber beams, steel walers, plywood and related components.
For the basic panel-system structure, see What Is a Panel Formwork System?. For H20 beam applications, see H20 Timber Beam: Sizes, Features and Uses.
How Is Trio Panel Formwork Built?
Trio-type systems use prefabricated steel-framed panels. Different panel ..
When evaluating used panel formwork, panel quantity and price are only part of the picture. Steel-frame condition, facing surface, weld areas, panel geometry and accessory compatibility together indicate the overall condition of the system.
See the current Used Panel Formwork product page. For the overall system structure, see What Is a Panel Formwork System?.
Steel-Frame Condition
The steel frame forms the main structural body of a panel. Bending, impact damage, visible deformation and heavy corrosion can affect panel condition and alignment. Corners and joint areas are especially useful wh..
Shoulder-type and high-frequency concrete vibrators can both be used to compact fresh concrete, but their mobility and working arrangements differ.
Shoulder-Type Vibrator
The motor unit moves with the operator, making this format useful where frequent movement around the jobsite is important.
High-Frequency Vibrator
High-frequency poker vibrators are available with different head diameters and can suit planned concrete-placement work where head size and access are important.
What Determines the Choice?
Mobility, reinforcement spacing, concrete-section dimensions, expected duty cycle and hea..
Formwork vibrators and immersion concrete vibrators compact fresh concrete in different ways. The main difference is how vibration is transferred into the concrete.
Formwork Vibrator
A formwork vibrator is attached externally to the formwork and transfers vibration through the form face.
Immersion Vibrator
An immersion or poker vibrator places the vibrating head directly into fresh concrete. Head diameter must suit reinforcement spacing and available access.

Table shoring is a modular temporary support system used below reinforced-concrete slab formwork. Frames, cross bracing, lower and upper adjustment components and H20 timber beams can work together as one organized slab-support arrangement.
Where Is Table Shoring Used?
Table shoring can be used in repeated slab areas, larger formwork zones and buildings with regular structural grids, depending on project requirements.
Main Components
Table-shoring frames
Cross and tension bracing
Lower adjustment spindles
U-heads or 4-way heads
H20 timber beams and form-facing surface
Compatible connection ..
If a concrete vibrator motor runs but the poker head does not vibrate, the fault may be somewhere in the mechanical drive path between the motor connection and the head. This article focuses on fault symptoms, not repair instructions.
For maintenance and hose replacement, see Concrete Vibrator Repair and Hose Replacement.
Motor Runs but the Head Does Not Vibrate
The coupling, flexible shaft or poker-head mechanism may no longer be transferring motion correctly.
Weak or Intermittent Vibration
Wear in the flexible shaft, loose connections, a crushed hose or wear in the head mechanism can prod..
Concrete vibrator selection should consider more than motor power. Poker-head diameter needs to fit reinforcement spacing, concrete-section dimensions and the available access inside the formwork.
50 mm
A smaller head can be easier to move through tighter reinforcement or restricted formwork areas.
58 and 60 mm
These mid-range diameters can suit a range of wall, column, foundation and general concrete applications depending on reinforcement spacing and access.
65 and 80 mm
Larger heads can be considered for larger concrete sections, but they may not physically pass through dense reinforceme..
Concrete vibrator repair and maintenance involves the motor connection, outer hose, flexible shaft and poker head working as one mechanical drive system. Heavy use, sharp hose bends, impact and wear can reduce vibration performance over time.
This article focuses on repair, maintenance and hose replacement. For fault diagnosis when the motor runs but the head does not vibrate, see Concrete Vibrator Not Vibrating?.
