1. General information about the product

Monzon Modular is a modular scaffold made of prefabricated components. Standards, transoms, ledgers, double guardrails and diagonal braces are the basic components in this scaffold. These can be assembled together to create scaffolds with a variety of different widths and lengths. For more flexible construction, there are rosettes on the standards at 0.5 m intervals vertically, which means

that the transom level (the height to the transoms) can be adjusted at 0.5 m intervals. Aluminium, steel decks or combi decks are used as scaffolding decks/decking in the scaffold. These are also available in different lengths and widths that can be combined to create the preferred dimensions. The decks are made of aluminium or galvanised sheet metal. The combi decks are made of aluminium/plywood or aluminium/fibre glass reinforced plastic. Modular is a very flexible scaffold system that is easy to erect and can be used for a variety of applications. This system is particularly well suited to façade scaffolding, unloading towers, mobile scaffolding, weather protection scaffolding, bridges, industrial scaffolding, mobile stages and suspended scaffolding. Modular can be selected with 2 different transom/deck systems, the traditional U transom system and the new PSI transom system known as No Limit, patent pending. The No Limit system is matric based entirely on both length and width measurements, which making it even more flexible. The decks/combi decks are available in 0.25 m and 0.5 m widths and 0.25-3 m lengths. Transoms are available in 0.25-3 m length. The transom profile is known as PSI (ψ).

1.3. Safety and responsibility

Modular is type examined by the Technical Research Institute of Sweden in accordance with the

requirements in EN 12810, EN-12811 and national regulations.

The system is approved for scaffolding in load class 2-6.

Type examination certificate number 39 44 03.

The components in the system have been developed using the latest 3D-CAD tools, and FE analyses have been carried out during product development process.

1.4. Attachment points for personal protective equipment (safety line)

Before erecting or dismantling scaffold, it is necessary to ensure that everyone involved has the

correct education/training according to national regulations.

To prevent accidents, a safety line and other safety equipment must be used when the scaffold is

more than two metres high.

Risk of

falling Safety helmets must be worn 3

1.5. The wedge connection principle

To achieve a scaffold structure that is robust, quick to erect and flexible, Monzon Modular has a

wedge connection consisting a rosette, a wedge-head and a wedge. The rosette has four small

holes and four large holes which make it possible to build in a variety of different directions. To

install the wedge connection, follow steps 1-3 below.

Step 1. Move the wedge-head towards the centre of the standard.

Step 2. Insert the wedge in one of the holes on the rosette (small hole is normally used for U transoms and ledgers).

Step 3. Tap in the wedge using a hammer to achieve a robust connection.

Angles To create a perpendicular scaffold, use the small holes at 90° to one another. Between the small holes is a larger hole which allows 45-60° connection to the rosette. This may be useful for triangular signboard scaffolds or hexagonal towers.

10 www.monzon.se

1.6. Maintenance

All scaffold components must be inspected carefully before commencing assembly. Scaffold

components which are bent, cracked, buckled, broken or warped are defective and have a dramatic

effect on strength. Under no circumstances may these be used in the scaffold – they must be

discarded. Components should be handled with care during assembly/disassembly, and packing of

the materials on appropriate supports/pallets is recommended in order to minimise transport

damage. If necessary, moving parts such as locking hooks for decks/combi decks and toe board

ends in the No limit system shall be lubricated.

1.7. Labelling

Most components in the Modular system are permanently labelled with MONZON and a combination

of four digits which indicate the month and year in which the part was produced (e.g. MONZON 1701).

Most components also come with stickers indicating the component dimensions.

3. Assembly

3.1. Assembly of basic scaffolding

3.1.1 Preparations and criteria before starting assembly.

Read chapter 1 carefully before starting assembly. Then check that the ground and sole plate have sufficient load-bearing capacity to handle the pressure from the scaffold on the base jacks. Sole plates decks are used to distribute the pressure over a larger area. Also check the ground level and start erection at the highest point, if possible.

3.1.1. Erection of the scaffold base

Position the sole plates, base jacks and base ledgers as shown in the illustration. Make sure that the distance between the wall and the deck is as small as possible, and no greater than 300 mm.

Transoms and ledgers can be laid out on the ground as illustrated to make it easier of positioning the base jacks. Note that base collars and ledgers must always be used at the bottom of the scaffold. If ledgers or standards have to be removed at an entrance or gate, for example, see the section entitled

Bridging areas and openings in the scaffold.

Always use base collars at the bottom of the scaffold.

3.1.2. Level adjustment

Fit ledgers in the small holes on the standard rosettes (see section 1.5 the wedge connection principle). Do not fix the wedges in position until the base jacks have been adjusted so that the ledgers are level. Also check that the angle between longitudinal and transverse ledgers is 90 degrees.

20 www.monzon.se

Use a spirit level or similar instrument to facilitate level adjustment. Ledges at the base can be replaced with U/PSI transoms if preferred. The standards are moved to the preferred level at intervals of 0.5 m in areas where the ground

slopes more severely. 80 cm base jacks may need to be used here.

Spacings for various base jacks:

40 cm 5-25 cm 60 cm 5-45 cm 80 cm 5-60 cm

3.1.3. Installing standards in base collars

When the wedges on the ledgers are fixed in position, standards or frames are inserted onto the base collars and base jacks as illustrated. Make sure that the standards/frames are inserted all the way onto the base collars. The standard length selected is dependent on the purpose of the scaffold. 3 m standards are normally used in the bottom of the scaffold and shorter standards (0.5 m, 1 m, 1.5 m, 2 m) at the top

of the scaffold in order to reach the right level. Offshore standards with bolted spigots must be used for suspended scaffolds.

3.1.4. Installation of U/PSI transoms

Now install U/PSI transoms as illustrated.

WARNING

21 www.monzon.se

3.1.5. Installation of decks

Now decks can be mounted on the transverse transoms in the scaffolding level. There are different deck types to choose from – see the list of components and permitted loads.

3.1.6. Installation of vertical diagonal bracing

The vertical diagonals brace is mounted in the large holes on the standard rosettes and on the outside of the ledger as illustrated Note: Check that the standards are vertical before fixing the wedges. Vertical diagonals braces must be mounted in the outer standards and in at least every

fifth bay longitudinally. If double guardrails are used, vertical diagonal braces can be excluded. Note that in this case, it is also necessary to install double guardrails in every other bay 1 metre from the ground, as a minimum.

3.1.7. Installation of guardrails

There are 3 different guardrail options in this scaffold system: Option 1: Ledgers mounted 0.5 m and 1.0 m from the transom layer. Option 2: Guardrail in the form of a double aluminium guardrail.

Option 3: Guardrail in the form of a double steel guardrail.

3.1.8. Installation of double guardrails

Step 1.

Angle the guardrail towards you and insert the lower wedge pin in the holes on the lower standard rosettes.

Step 2.

Rotate the upper guardrail tube towards the standard rosettes,

mount the upper wedges in each standard rosette and then tap the wedges into position using a hammer.

3.1.9. Installation of deck locks for U transoms

Position the deck lock over the transom and pass the hooks down through the corresponding holes in the U transom. Then push the lock sideways so that the hooks lock the deck in position as illustrated. Then rotate the lock plate towards the U transom as illustrated.

Rotate the lock plate

23 www.monzon.se

3.1.10. Locking decks/combi decks with PSI transoms

The locking arrangement for decks/combi decks in the No Limit system is integrated in the two end pieces of the deck, located on the underside in the form of locking hooks. The locking hooks are pushed into

their locked positions, locking the deck/combi deck to the PSI profile. This is done by rotating the locking hook and pushing it into the end position/locking position for locking hooks. The locking hooks are spring-loaded and can be locked and unlocked as illustrated. During installation, make sure that the locking hooks have been locked and that the decks are firmly in position. Lubricate the locking hooks with grease if necessary and during maintenance.

3.1.11. Installation of toe board (U transom system)

Start by installing toe board

pins on the standards where toe boards are to be installed. The toe board pins are fixed in position using wedges. The toe boards are then threaded onto the round bars on the pins. Note that the ends and long sides of the scaffold use different toe boards.

3.1.12. Installation of No Limit toe board

No toe board pins are needed when installing toe boards in the No Limit system. One end of the toe board is spring-loaded and the end is locked directly against the standards, as illustrated. Spray grease onto

the moving end piece if necessary and during maintenance.

3.1.13. Installation of wall ties

Wall ties are one of the most important parts in a scaffold system. The locations and numbers of ties have a major impact of the load bearing capacity for the scaffold and max scaffold building height. Therefore, always follow the instructions in these assembly instructions or contact Monzon

for more information. Wall ties are normally fitted to all inner standards at every 4 metres of height and beneath the topmost transom layer. Wall ties are normally secured to the scaffold’s inner standards using couplers and are frequently positioned directly beneath the transverse transom. There are a number of different wall plug anchor types, such as eyebolts + plugs, expanding plugs, chemical anchors, anchor bolts, anchor bolts with related angles to metal walls, etc. The plug anchor type to be selected is dependent on the nature of the wall and the requisite pulling force. Eyebolts and plastic plugs are used together with wall ties and fixed couplers in the illustration. Wall ties should be tested using a wall tie tester/dynamometer, in order to be sure of the

extent to which a wall tie can be loaded.

Straight wall tie in a concrete wall.

V-shaped tie must be mounted in order to absorb any horizontal loads that may occur. V-shaped must be mounted on every 5:th pair of standards, and always in the outer bays. If greater horizontal loads may occur – in the case of a cladded scaffold, for example – with wind loads parallel to the façade, the requisite number of straight and V-shaped must be mounted, particularly in the standards nearest to the ends of the scaffold.

3.1.15. Installation of external staircase

External staircases are mounted as illustrated. External guardrails are mounted on the outside of the staircase, and you can choose between 2 x single guardrails or one double staircase guardrail. You can

install an internal guardrail as a handrail on the inside of the staircase. A ledger is normally installed at the topmost deck level. An O- spigot and a 1.0 m standard are mounted on this ledger, along with shorter ledgers or double guardrails and toe boards to

make an opening – see the illustration. End toe boards are installed at the start and end of the staircases, as illustrated.

3.2. Bridging with lattice beam 750

If bridging is needed, a lattice beam connector artno 213.075 is installed together with lattice beam 750, bolt with spring locks and Ø38mm lattice beam spigots. U standard joints and rosette couplers are mounted in the middle of the beam.

4 x vertical diagonals are mounted on the next deck level, as illustrated.

2 x additional wall ties are mounted on standards adjacent to the opening 2-2.5 m from the ground, as illustrated.

32 www.monzon.se

A further 4 x vertical diagonals must be installed when scaffolding is erected to greater heights. Contact Monzon for more information.

If it is necessary to remove ledgers at the base of the scaffold, you must not remove so many that you leave just “one pair of standards” in place. There must always be

ledgers linking the standards together.

3.8. Brackets

If necessary, the scaffold can be made wider using brackets. The brackets can also be adjusted vertically at intervals of 0.5 m. U brackets are available in 0.39 and 0.73 m widths. PSI brackets are available in 0.25, 0.5 and 0.75 m widths.

3.9. PSI connectors

PSI connectors are used as variable attachment points to

ledgers or PSI transoms or standards. These are mounted up on the PSI transoms.

39 www.monzon.se

PSI transoms and PSI decks have 0.25 m length intervals

which make it possible to combine them and create a range of different configurations, to create a pipe penetration in the deck level, for example. The design of the

decks makes it possible to install transoms/beams between the decks, leaving no spaces between the decks. This is applicable even when brackets are used.

4. Dismantling

4.1. Preparations prior to dismantling

Check that the scaffold has been cleaned and that there are no loose objects on the transom layers. Check that all wall ties are in their correct positions (someone may have removed the ties). Check that all parts of the scaffold are positioned correctly (someone may have removed parts). Cordon off the area around the scaffold so that there is no unauthorised access to the area adjacent to it.

4.2. Implementation The scaffold is then dismantled in reverse order to erection. Make sure you check the parts removed to ensure that they are not:

• Cracked

• Buckled

• Bent

• Broken Any parts damaged must be discarded. The materials should be loaded onto pallets or similar to prevent them being damaged during transportation. Never throw parts down from the scaffold!

If a removable rosette coupler is to be used as a replacement fixing point for system-bearing

components, the global load-bearing capacity and permitted standard load may be affected and

special investigation of the load-bearing capacity must be carried out. Please contact Monzon

Sverige AB if necessary.

8.3. Anchoring forces

The maximum design anchoring force perpendicular to the façade is 2.5 kN.

The maximum design anchoring forces at ties that can absorb horizontal forces (V ties) are 4.0

kN and 4.8 kN parallel and perpendicular to the façade, respectively.

Greater wind loads may occur in the case of a cladded scaffold and/or at heights in excess of 24

m, and hence higher anchoring forces may occur.

8.4. Maximum design force on the ground

Is 25 kN/standard, if bracket 25 kN/standard and in the case of bridging 29 kN/standard.
