At Jackson & Gocher Hire Centre, we provide a full bird cage scaffolding service which is very popular with our clients, due to its accessibility and safety.
When it comes to bird cage scaffolding systems, Jackson & Gocher are unbeatable for the products that we provide to customers across the UK.
Bird cage scaffolding is a simple design and is usually used when it comes to one level use, for example, if you’re working on a ceiling. The structure stands on its own and is easily assembled which makes it perfect when it comes to smaller contained projects.
A birdcage scaffold is also known as an independent scaffold, they consist of more than two rows of standards (poles) and are connected by ledgers and transoms at every lift height. The top lift boarded to form the access platform for work on ceilings and soffits, this allows for light fixing, access ventilation points and sprinklers. Birdcage scaffolding can also be erected to more than one lift height, both indoors and outdoors.
The birdcage scaffold is built to be robust and sturdy so you and your tradesmen can work safely when it comes to ceilings, walls, floors on platforms and scaffold stairs. What’s more is when you choose Jackson and Gocher we take risk control measures to ensure the quality of work platforms and your peace of mind.
There are two types of birdcage scaffolding…
Birdcages with more than one lift height
Single lift birdcages
The standard size should be a maximum of 2.5m in each direction. The first lift can be up to 2.5m high if necessary when it comes to access below the scaffold, otherwise lift heights should in general, be 2m intervals.
This is except for when the working lift is in the outside bays, a birdcage should have only one working lift such as the top lift and the loading bay should not exceed 0.75kn/M2.
If the birdcage scaffolding needs to cover a large plan area, then the width of the edge bays can be reduced to three, four or five boards to meet the requirements for the particular type of access which is required around the edges.
Ledgers and transoms should be fixed to the standards along with the right angle couplers, the top lift transoms should be fixed to the ledgers with putlog couplers. Transoms in working lifts can also be fixed to the ledgers to provide level support for the decking.
All birdcage scaffolds need to be braced or tied to make sure that they’re stable enough, standards need to be braced to ensure it’s strong enough to carry vertical loading. Birdcages should also be stiff enough to resist lateral sway and horizontal loads as well as being safe from overturning. External birdcages should also be braced in order to resist wind forces as well as being anchored when necessary.
Bracing should be provided at the rate of one brace for every six standards in each line, bracing in each direction should be attached to the ledgers or transoms by right angle couplers. If this can’t be done, then to the standards by the means of swivel couplers.
Where an adjacent structure is available, a birdcage should be stabilised from it, if it’s possible then all four sides should be secured. Where two opposite walls are available, it’s sufficient to arrange tubes to provide space against them from each side, if only one is available then it’s necessary to provide a two-way tie.
The most satisfactory details is to extend the transoms or ledgers, where they are to touch both ends, timber packing and reveal pins can be used.
In this decking, there’s no permissible gaps for the platform, platforms should be further than 150mm from the working edge, unless they’re provided with guard rails and toe boards. Where scaffolds have more than 11 standards in a line, it’s not possible to rely on wall support only as some standards will be too far from a support in one direction. Bracing is essential but can also be used in conjunction with tying and butting using intermediate parts of the structure.
Any birdcage is higher than 50m and should be designed specially as a general rule to include alternate rows of standards which would be braced.
Single lift birdcages should have special attention paid to the bracing of any height less than 2.5m, the absence of the braced upper lifts then requires that the stability of the deck is derived from one lift of bracing only, this should then be correctly positioned and fixed.
The standards should be supplied with foot ties in alternate bays in both directions to form the boxes. Diagonal bracing of the alternative boxes in two directions should be fixed, ledgers or transoms should be joined with sleeve or parallel couplers. No materials should be stored on the birdcage unless it comes with specially designed storage areas.
