1.2.4. Hydraulic system

In this case, motion is via a hydraulic jack fixed to the top part, whose plunger drags an axis that has been previously placed on the central vertical tube.

D Vertical tube

Main component of the system available in 3 different heights. It is placed on the corners at 90°, fixed on the formwork panels on each side.

The system basically operates by trying to push the central vertical tube upwards and downwards. Thus the tube drags connected hinge plates which, in turn, transfer the horizontal motion to the mobile parts, which contract or extend depending on the direction of the vertical displacement of the tube.

The displacement of the central vertical tube (i.e. the operation of these corner panels) can be carried out in two different ways:

1.2.3. Manual-crane system

The motion is effected on a vertical head fixed onto the corner panels and connected in turn to the vertical tube. The head has two holes for manual drive using the stripping handle or the crane slings in one direction or the other.

2. SOLUTIONS

2.1. INTERIOR WALLS

Formwork stripping corners shall be used to facilitate formwork stripping on interior walls.

A corner panel shall be placed on each right angle corner tied to the contiguous modular panels using ORMA clamps.

POURING POSITION

When the mobile parts of the corner panels are stripped, they are displaced towards the inside, making the whole formwork set contract, separating from the wall by a few centimetres.

STRIPPING POSITION

3. 3.1. CONNECTION BETWEEN PANELS AND CORNER

PANELS

Formwork stripping corners are connected to the ORMA panels via the ORMA clamp.

• 3.3 corner panel: 3 clamps vertically arranged.

• 2.7 corner panel: 2 clamps vertically arranged.

• 1.2 corner panel: 2 clamps vertically arranged.

Clamps must not be placed at the same height in order to avoid collisions between clamps during formwork stripping.

3.2. FORMWORK ASSEMBLY PROCESS

All formwork stripping corners have a locking pin on the top part of the central tube.

If the pin is inserted into the tube, the tube cannot move in the vertical direction, so the corner panel is locked.

If the pin is removed from the tube, then it is free for driving in the corner panel closing and opening operation.

LOCKED UNLOCKED

When assembling the panels with their corner panels, the latter must be in the open position so that each side measures its standard 30 cm.

If the locking pin is released, the mobile parts may be in a position that is not fully open, it being necessary to pull them until their correct measurements are obtained. This is achieved using the stripping handle to exert its driving force on the inner hole of the head.

Once you have made sure that the corner panel is fully open, place the locking pin on the vertical tube and the ORMA panels can be assembled onto the corner panels using the ORMA clamps.

It is important to apply release agent on the surfaces in contact with the concrete.

It is recommended that you place adhesive tape between the joints of the mobile and fixed parts.

4. SYSTEM PROPERTIES

4.1. CONCRETE PRESSURE

To calculate the pressure of fresh concrete on formwork, we use the German standard DIN 18218:2010.

These are the variables to be taken into account for this calculation:

Density of fresh concrete (the normal value is 25 kN/m3).

Curing time (may vary between 5 h and 20 h).

Temperatures (reference, pouring and minimum temperature until curing is complete). Depending on the value of these temperatures, final pressure must be increased or decreased by a percentage, (see DIN 18218:2010).

Concrete consistency class (F1-F2-F3-F4-F5-F6 and SVB).

Concrete pouring rate (between 0 and 7 m/h).

Below is a calculation table for hypothetical curing time = 5 h (depending on curing time, different tables are shown in DIN 18218:2010).

Calculation of fresh concrete pressure in accordance with DIN 18218 is only valid for angles within ±5° with respect to the vertical.

6. TERMS AND CONDITIONS OF USE

6.1. SAFE OPERATING GUIDELINES

6.1.1. General guidelines

• Strict adherence to all instructions included in the Project Plan, the Health and Safety Plan, and any further applicable technical and/or safety regulations is strongly recommended.

• All work activities must be carried out by qualified personnel under the oversight of a competent supervisor.

• All instructions for the proper use of the equipment employed on the worksite must be followed. Consult manufacturer or distributor operating manuals whenever applicable.

• Only approved auxiliary equipment and appropriate protective equipment – preferably Collective Protective Equipment (CPE) – are to be used.

• Personal Protective Equipment (PPE) must include the following: safety helmet, safety footwear, protective gloves, and tool belt. Further PPE – including reflective jackets, anti-fall harnesses with lifelines, safety glasses, Respiratory Protective Equipment (RPE), ear-plugs, etc. – should be used whenever conditions so require.

• Avoid heavy impacts on working platforms and panels. It is strictly forbidden to jump, abruptly unload material, or subject either the platforms or panels to similar stress.

• If the building site is located nearby high voltage power lines, it is recommended to work without using electricity whenever possible. If this is not possible, all appropriate safety measures outlined in the applicable standards must be taken.

• Under adverse weather conditions, all work with building material on the worksite should be halted.

• In the event of a storm with heavy winds, remove all equipment and material from the platforms, ensuring both before and after the storm passes that all ties, meshes, platform anchorages, etc. are properly secured.

• Before starting the stripping and dismantling process, ensure that all structural components (e.g. ties) are in place. If they are not, examine the entire structure before proceeding.

• Furthermore, ensure that no loose material remains on the structure (e.g. working platforms) that could fall and injure people below.

• The following measures must be taken to restrict access to the structure during erection, dismantling, and at any other time during which it is not in proper working condition (e.g. missing CPE): signposting, fencing, and the use of warning tape, barriers, or meshes to enclose and clearly demarcate the working area from zones of public passage.

• Employees and any third party accessing a structure without the CPE yet in place must use all PPE indicated to prevent falls from height and to be protected from falling objects.

• The purchaser or lessee of the structure shall inform and instruct its employees to comply with all guidelines necessary for safe use.

• Any alterations to the structure must be executed under the oversight of a competent supervisor and must comply with the instructions in the operating manuals of the manufacturer or distributor.

• The purchaser or lessee shall conduct periodic inspections of the assembly to verify the correct installation of critical structural elements, as well as ensure that no employees or third party has removed or altered any other aspects of the structure.

6.1.2. Guidelines for formwork

• Formwork

• An appropriate chassis framework must be used to protect the formwork panels from damage, as well as facilitate orderliness, cleanliness, and transportation to the point of use.

• Ensure that plate nuts are properly fastened, and that all push-pull props are correctly positioned and anchored to the ground.

• All panel joint clamps must be perfectly wedged into place, so as to prevent slurry from escaping through the joints.

• No formwork assembly shall be set in place before ensuring that the previous assembly is properly anchored.

• Do not leave any structural components partially assembled.

• It is forbidden to climb on formwork except in extraordinary cases when risks have been duly studied and all appropriate protective systems are in place.

• Before pouring concrete, make certain that all formwork surfaces are clean.

• Clean panels after each use. Wire brushes are not suitable cleaning tools, as they can damage the phenolic coating.

• It is important to note that the phenolic coating is rarely damaged by the chemical and abrasive action of the concrete. But where it is already damaged, e.g. at holes and deteriorated areas, it must be thoroughly sealed to prevent any further damage.

• Any cut made in the panelling should be sealed as soon as possible, given that cut edges soak up water from the concrete and swell, thus creating irregularities in panel thickness.

• In general, it is not recommended to use nails or screws on the panels.

STRIPPING CORNER MAX // 19

• When not in use, panels should be stacked on top of each other with wood runners set between them and stored so as to avoid direct contact with both the ground and the elements. Prolonged exposure to sun and rain can cause damage.

• Release agent

• The release agent helps to separate the formwork from the concrete, and thus increases the working life of the panel.

• It plays an important role in a quality of the finish by providing a uniform colour and preventing the pitting that can occur due to air bubbles formed between the concrete and the formwork surface.

• Apply the release agent uniformly and in thin layers onto the panel, always bearing in mind the instructions for correct use.

• Thoroughly clean the panel surface before applying the release agent to it.

• Clean the metal frame and panel of all residual release agent after every 4 to 5 uses.

• Pouring the concrete

• Do not exceed the maximum pressures indicated in the instructions of the formwork system in use.

• Continuously check the state of the formwork during concrete pouring. Stop further pouring in case of any incident.

• Pour the concrete in uniform layers of 30 cm to 45 cm.

• For vertical concrete pouring, pour from as close above the formwork as possible. Never pour from an excess of 2 m unless a nozzle or similar accessory is used to channel the concrete. Deposit the concrete as near as possible to the formwork base, centring on one point without pouring directly against the formwork.

• When pouring with a skip take special care to avoid hitting the formwork, and do not exceed the maximum load-bearing capacity of the crane.

• Avoid splashing the panelling with concrete, as the marks will be visible on the finished surface.

• Use appropriate compaction and vibration methods that allow the concrete to be worked properly.

• Poker vibrators are the preferred compaction and vibration method for wet cast-in-place concrete. Use external vibrators only when the concrete cannot be accessed with poker vibrators or when placing pre-cast parts. A technical analysis must be undertaken to determine the specific external vibration method required.

• Completely immerse the poker 10 cm to 15 cm into the concrete.

• Never allow the vibrator to touch the formwork to avoid exceeding the designed loads.

• Immerse vibrators quickly, at a vertical or slightly inclined angle, and keep them in a fixed position.

• Vibrators should be removed slowly.

• Curing the concrete and stripping the formwork

• Check that curing is sufficiently advanced for stripping to be performed without causing surface spalling, which would destroy the finish and potentially affect the strength and durability of the structure as a whole.

• Increase the curing time when faced with conditions such as wind or low temperatures that favour rapid drying and shrinkage.

• The time between casting and stripping should be uniform for all parts of the concrete structure. This is especially true when a high quality finish is required, because surface colouring is determined by the length of time that the surface remains protected from atmospheric influence.

• Ensure that no unauthorised people are present in the vicinity when stripping takes place.

• Once an assembly has been stripped it must be placed on a chassis framework, where it is to be cleaned and dismantled if it will not be used for subsequent pours.

6.2. TRANSPORT, HANDLING AND STORAGE

6.2.1. General guidelines

• Inform yourself about the hazards present on the building site and the preventive measures necessary to avoid them.

• Follow all instructions given by the project foreman.

• Ensure that there is adequate communication between all employees working together.

• Use equipment only when authorised, specifically trained, and informed as to proper use.

• Maintain a minimum safe distance from all mobile work equipment (including forklifts, lorries, cranes, and other construction machinery), as well as from areas that present a risk of falling objects.

• Do not stand, walk, or work under suspended loads, nor in the trajectory or in the vicinity of these loads.

• Protect material from collision and crushing during transport, handling, and storage.

Page 20: STRIPPING CORNER MAX · 4 // STRIPPING CORNER MAX 1. PRODUCT DESCRIPTION 1.1. INTRODUCTION The MAX Stripping Corner is the ideal solution for stripping formwork in interior spaces

20 // STRIPPING CORNER MAX

• All material is to be packed for transport in appropriate containers such as wood or steel pallets, boxes, or strapped in bundles with a stable base.

• Strap bundles in a sufficiently stable manner so as to prevent them from moving and getting damaged. If necessary, protect the items with additional safeguards.

• When cutting straps, stand to one side and use gloves and safety glasses; guard against the danger of being cut by the strap or caught by the freed material.

6.2.2. Transport

• Ensure that material is stably loaded, complying with the instructions of the driver. Watch for balanced distribution on the lorry bed, make sure that all auxiliary items are properly fastened, etc.

• Keep your distance when opening the containers after transport to prevent injuries from falling objects.

6.2.3. Handling

• Manual load handling

Some ergonomic principles to be followed are as follows:

• Avoid making brusque movements.

• Before lifting the load, examine it to detect any sharp corners, dirt, etc. and decide, according to its shape, weight, and volume, the best way to get a secure grip on the load.

• Lift by separating your feet to shoulder distance, and crouch down by bending at the knees, never at the back.

• Use a mechanical lifting device and/or ask for help from co-workers when lifting heavy or awkward materials.

• Mechanical load handling

• Use only approved mechanical lifting devices appropriate for the operation.

• Check the condition of slings, cables, and any other lifting accessories before each use.

• After fastening the lifting accessories and before lifting begins, step back to a safe distance from both the load and any other materials which could be affected by the load.

• Comply with all instructions given by the specifically-trained equipment operator.

• The load is to be lifted gently, without any brusque movements.

• When conducting difficult or dangerous lifting operations, or when the crane operator lacks a view of the entire load trajectory, crane operations are to be directed by a signaller in constant communication with the operator by means of a previously agreed-upon code of signs.

• If necessary, use taglines to guide the load from a distance.

Loads are never to be guided by hand whenever there is a danger that the rigger could be trapped by the load. Swinging and/or unforeseen movements of the load can cause serious accidents.

6.2.4. Storage
