The Problem

With traditional basement shutters

When creating underpins in basements, formwork is necessary to retain the concrete whilst it cures.

Using conventional timber methods the workers have to construct the shutter in the hole and can be there for prolonged periods of time, these shutters are heavy and are usually demolished once the concrete has cured and have to be re-build in the next hole.

The other problem usually found is that the timber panels tend to float when the concrete is pored behind them which could lead to the shutter bursting.

The Solution

A patented, unique new design

We have designed a light weight interchangeable steel construction panel with a timber face which are available in one standard width (1220mm) and various lengths from 250mm to 1800mm.

Our Panels

Our panels are lighter than the conventional panels and do not require the workers to spend prolonged periods in the hole, once the concrete has cured the panels can be easily lifted out the hole and transferred to the next one without need for deconstruction.

Our Brackets

We have also designed various brackets which attach to our shutter panels to allow the user to back prop horizontally or diagonally and secure the panels against almost any soil conditions.

Anti-Lift

We also have an anti-lift bracket which secures the shutter panel at its base and does not allow it to lift.

FIGURE 1
The shutter panel (1) is constructed using light weight steel rectangular hollow section with holes in the top and bottom (2) for fixing the panels together or to an anti-lift bracket and holes up the vertical members (3) to allow the 90° or 45° brackets to be securely fixed to the panel, there are horizontal members (4) which have holes in them to allow the ply wood facing board to be attached.

FIGURE TWO
The 90° support bracket (1) is made from light weight steel angle with a plywood insert (2) to allow the fixing of acrow props and a pin (3) to securely fix the bracket to the shutter panel.

FIGURE 3
the 45° support bracket (1) is made from light weight steel angle with a plywood insert (2) to allow the fixing of acrow props and a pin (3) to securely fix the bracket to the shutter panel and features a back plate (4) which stops over rotation of the bracket.

FIGURE 4
The spreader plate (1) has a light weight angle square (2) welded in the center to allow a ply wood insert (3) to securely fix acrow props to it and holes (4) in the corners for ground stakes.

FIGURE 5
The drag beam (1) is made from light weight steel rectangular box section and has plates (2) welded to the beam with holes (3) for ground stakes. The drag beam had holes down its length (4) to allow 45° brackets to be securely bolted to the beam.

FIGURE 6
The drag beam 45° bracket (1) made from light weight steel angle and plate with a ply wood insert (2) to allow the fixing of acrow props and a long threaded bolt (3) to allow the bracket to be securely fixed to the drag beam.

FIGURE 7
The anti-lift bracket (1) is made from steel angle and has holes (2) to fix it to a wall or kicker and holes (3) to connect the anti-lift bracket to the shutter panels.
