– and i ts ingenious Allround technology
It’s the Allround Connector that gives you the edge: design, top-quality material and precision manufacture by Layher guarantee stability, quality and safety.
The »Original« Layher Allround Scaffolding® For demanding and complex scaf-
folding applications – i. e. wherever
conventional scaffolding technology
falls short of optimal thus cost effec-
tive use, Layher Allround Scaffold-
ing convincingly comes in with an
unmatched range of advantages:
unbeatably fast assembly, persua-
sive economic arguments and an
extensive range of series-produced
accessories. This and more is avail-
able thanks to allround versatility
from one system.
Connections in this quick to assemble
and spannerless scaffolding system
make a unique combination: providing
structural strength immediately on
assembly and subsequent ultimate
force transmission while offering a
choice of automatically right-angled
or splayed connections with unrival-
led safety right from the start.
Layher Allround Scaffolding has
become a by-word on the market for
both modular scaffolding and out-
standing quality.
Layher Allround Scaffolding is an
investment in a perfected and com-
plete system – in steel or aluminium
– with all the necessary approvals,
and rapid, safe, highly versatile and
continually profitable scaffolding
construction.

The Allround Force Connector makes it possible.
. . . the component is immediately secured against any possibility of shifting or dropping out. That means: safe 1-man-assembly, whatever the height.
Structural assembly from the beginning: By sliding the wedge head over the rosette and inserting the wedge into one of the holes . . .
A blow with a hammer on the wedge transforms the connection from structural assembly to force transmitting rigidity.
For industry, chemical plants, power stations, aircraft hangars, shipyards, theatres and arenas, at any site or facility, the “Original” does full justice to its reputation as an all-rounder.As work and protective scaffolding at the facade, as birdcage, tower and suspended scaffolding, or as a rolling tower – the right scaffolding at all times and for all jobs and requirements.
For very difficult ground plans and anchoring conditions, for very irregular structures, and for jobs with increased safety requirements.
The flat rosette without recesses or raised edges prevents clogging with con-crete, sprayed foam, dirt etc. that might otherwise hamper assembly.

What use is a spannerless con-nection if the time saving is lost by having to measure for right angles?
Built-in assembly speed: the fournarrow holes in the perforatedrosettes centre the ledgers auto-matically and securely at rightangles – while the four largeholes permit the alignment ofledgers and diagonal braces atthe required angle.
Forget about ... ... lengthy measuring and levelling,... time-consuming spanner work,... repeated adjustments,... tube/coupling entanglements,... undefined structural
force situations ...
The wedge head is precisely matched to the radius of the standard at the front end – so forces are applied to a surface not a line and always centrally into the standard.
The result of superior design: up to 8 connections at various angles can be made in one plane with the structurally ideal Allround Connector. The assembly of the system is straight-forward.

Z-8.22-64: The Allround Modular System in steel (version K 2000+ and former version [Variant II])
The Layher Allround connector K 2000+ was developed by optimisation from the Allround connector which has been proving its worth since 1974.
The Layher Allround connector K 2000+ shows compared with the former Allround connectorA substantially higher loading capacitiesA bending moment of ledger connection: + 49 %A vertical diagonal braces: +113 %
That means: Material savings.More possibilities.
A Compatibility with Allround material of the former design is assured as a general principle. When K 2000+ diagonal braces are used with former Allround standards,
higher loading capacities are approved for these connections, see approval.
That means: existing material is »upgraded«.
The Allround Connector that gives you the edge: design, top-quality material and precision manufacture by Layher guarantee stability, quality and safety.
Layher Allround scaffolding has – in addition to its German approval – other national approvals in all the European countries, in which an approval system exists.

Approval for standard assembly.
Z-8.22-64
A Approval for standard assembly as facade scaffolding:Besides the approval for the Connector, Allround Scaffolding is also approved for assembly as facade scaffolding, meaning that assembly is possible with-out additional calculation.Vertical diagonal braces are not required in the standard assembly according to approval.
A For facades too, Allround Scaffolding offers the well-tried Allround benefits:
A low susceptibility to cloggingA »automatic« right-angled structureA versatilityA high loading capacityA decks can be fitted or removed at any point and at any time
A Allround Scaffolding is an intelligent and economical solution.
Particularly irregular facades and structures with curving ground plans can be enclosed economically and safely using Allround Scaffolding.
This is where Allround Scaffolding with its superlative adaptability offers an intel-ligent and economical alternative.

Allround Scaffolding in aluminium
Z-8.22-64.1
Possible applications in which the speci- fic advantages of the Layher Allround Scaffolding systems made of aluminium can be used to particular advantage in terms of both profitability and design ele-gance include
A rolling towersA suspended scaffoldingA scenery in theatresA for trade fairs and events
A a support base insufficient to with-stand the forces from a steel scaffold-ing structure
A historic natural masonry requires refur-bishing, but is crumbling under the effects of the environment and hence is unable to bear the weight of steel scaffolding.
A These are possible scenarios where the use of Layher’s Allround aluminium system is ideal.
Other outstanding arguments in favour of using Layher’s Allround in its aluminium version are:
A faster assembly A low loading weight A less physical strain on the assembly
personnel.
Layher Allround in aluminium can be used in conjunction with Layher Allround in steel, as both systems are compatible.

Standard configurationThe Allround wedge lock system offers an ideal and safe positive connection between standards, ledgers and diagonal braces.The system provides permanent safety for erectors and users alike. By applying a blow with a 500 g hammer, the joint is secured. Standard lift height is 2 m; other heights are possible but may require special components or procedure. Consult Layher for further information.
(7) All wedge connections must be knocked in with a 500 g hammer until the blow bounces.
For timber plank decking or when no decks are installed, longitudinal ledgers must be installed and, in every fifth bay, horizontal diagonal braces, each level.
(8) To extend scaffold further repeat steps (4), (5), (6) and (7).
Timber planks must be laid if required. Insert standard decks as stiffeners every 2 m apart in the upward direction as building work progresses.
(1) Starting at the highest point place threaded base plates at the required centres. Use soleplates where necessary to distribute the load.
For allowable loads and max. spindle extensions h (see page 17 and Tab. 20, page 20)
(2) Fit a collar over the threaded base plates.
(3) Connect collars using ledgers. Use the small holes of the rosette for right-angleconnections.
Then, level the base commencing at the highest point of the ground, by adjusting the wing nut.
(4) Fit standards, then at the next lift height connect one board bearer/ledger and two longitudinal ledgers (when using scaffold boards), or one U-transom and standard decking units with lock against lift-off plates.
Installation of 2nd transverse ledger 0.5 m above the bottom transverse ledger (in the case of facade scaffolding structures with more than 60 % of the permissible standard load).
(5) Select lengths of standards in such a way that the joints occur at either deck level or transom level.
(6 a) Tower-like (6 b) Large area configuration configuration
(drawings do not show anchorages)
Diagonal braces Allround scaffolding, at assemblies different from the standard assembly
(6) Fix diagonal braces according to static requirement. At standard scaffold assemblies according to approval vertical diagonal braces are not required. If required they can be fixed in every 5th bay in tower-like (6 a) or in large area configuration (6 b).

Scaffold deckingThe Layher system allows you to choose between decking elements made of hot-dip galvanized steel, aluminium, solid wood or an aluminium frame with plywood deck, depending on application, load class and your operational requirements. An inherent characteristic of all Layher decking elements is their reinforcing effect within the scaffolding. Longitudinal ledgers are not necessary; see also item (9).
(11) Overlapping on transverse ledgers
Timber deck according to Tab. 2, DIN 4420, pt. 3.
(12 ) Without height offset, butt-joined on support ledger with due consideration of support points.
Standard decking
(9) and (10) Suspend decks in U-transoms and secure them with lock against lift-off. Deck selected depending on loading and standard spacing.
Three-part lateral protection
(11 a) Mount one ledger at 0.5 mabove deck level as an interme-diate hand rail and at 1.0 m as themain guard rail. Attach toe boards to the scaffolding bays and to the ends.
(11 b) When overlapping timber planks are used as decking element and when the guard rail height is less than 95 cm, add an additional ledger at a height of 1.5 m.
(12) Place longitudinal and end toe boards behind the wedges.

Vertical diagonal braces according to static requirement.Standard scaffold assemblies according to approval do not require vertical diagonals. Also other assembly variants can be built without vertical diagonals according to static calculation depending on the scaffold height, the anchorage pattern, the existence of cladding as nets or tarpaulins, the loads and the scaffold width.According to experience assemblies deviating from the standard assembly can be built with vertical diagonals in every 5th bay.
Information on load-bearing capacitySelect the Layher scaffolding decks on the basis of the required load class and scaffolding width from Table 20 (standard decks); for wooden planks see table 23. If scaffold boards are used in service scaffolds suitable for cushioning the impact of a falling person the information in table 2 shall apply, DIN 4420, pt.1.
* Higher working loads are possible depending on the applications, but must however be verified.
The specified loads were ascertained on the assumption of 5 % horizontal load components. Spindle adjustment h: Adjustable base plate 60 and adjustable base plate 80; see page 17Dimensions between surface of base plate and top edge of wing nut

Allround Scaffolding in allround application
The Layher Allround Scaffolding reduces assembly times, labour costs and increases safety when erecting scaffolds around church steeples, monuments and restaurants in high places, for scaffolds at or in boiler plants, tanks and pipe lines, for scaffolds across working places, and supply lines, around machines, at or under bridges – scaffolds on construction sites or mobile scaffolds in tunnels. Simply each and every job can be carried out safer and quicker with Allround Scaffold-ing thus saving costs.The building industry is presenting in - creased demands for load-bearing capacity and assembly variability in scaffolding. This is where Allround Scaffolding is now setting new standards: a single system, as bricklayer’s scaffolding, work scaffold -ing, safety scaffolding or falsework, with 73 cm, 109 cm or 140 cm bay width, with selectable storey heights and live loads of up to 6 kN/m2 depending on the bay width. Or assembled as scaffolding for form-work or support: with Allround Scaffoldings you’re prepared for anything.

Structural scaffold – church towers
Due to the irregular structural shapes at or in churches scaffolding was extremely difficult in respect to safety and could only be erected requiring a lot of time with high costs involved. The Layher Allround Scaffolding proves here its adaptability – in quick, boltless assembly and dimensional precision up to the greatest height. Hence you create quickly safe working places for roofers, stonemasons, carpenters and stuccoworkers, for plumbers and glaziers – either inside or outside.

The high degree of variability and rigidity of Allround Scaffolding means that a wide variety of applications can be catered for, thanks to the use of a few additional parts. The use of stringers and guardrails allows the construction of stairways towers on sites as well as stairways for public access areas. Rolling towers can be built in all sizes and heights. Allround Scaffolding in con-junction with the Protect System allows weatherproof coverings to be provided, including complete facades for the purpose of asbestos removal.
