BMK CLIMBING BRACKETS

1. PRODUCT DESCRIPTION

The Climbing Bracket BMK system is mainly used for the construction of double-sided walls and piers. It is supported on anchor cones embedded in the concrete wall from a previous pouring stage.

The system allows of two different stripping options:

 With rack and pinion system: The formwork is supported on a carriage which enables to move it

back up to 80 cm from the wall. This system eases the cleaning and placing of steel reinforcement.

 With tilt-back system: The formwork can be separated some 5 cm from the wall for stripping and

moreover it can be tilted.

The formwork together with the climbing structure is moved up to the next pouring stage with crane.

Apart from all other necessary components for the formwork, the working platforms can be highlighted as constituting factors for product safety.

PLATFORM TYPES FUNCTION

CONCRETE POURING PLATFORM It is used for concrete pouring and for the hooking of the crane. VERTICAL WALER PLATFORM It is used to place and release the tie rods.

MAIN PLATFORM

This is the amplest working platform. It is used as working area for the stripping, approaching and plumbing of the formwork panel as well as for the placing of the steel reinforcement, tie rods and for the cleaning of the panel.

CONE RECOVERY PLATFORM

It is used to recover the cones left in the concrete from previous pouring stages and for the placing of the wind sling fixers.

The main features of the Climbing Bracket BMK system are:

 Use with different formwork products

: Mainly with ORMA modular formwork, beam-based

formwork (ENKOFORM V-100 and ENKOFORM VMK) and metal formwork.

 The climbing brackets/frames consist of standard walers MK with accessories bolted

to them. This

entails the following advantages:

o Very versatile system

: It offers the versatility of the MK system and enables different

configurations by making use of some MK accessories.

o Transport saving

: The brackets/frames can be delivered disassembled to the building site

which contributes to the reduction of transport cost.

 The climbing brackets are already equipped with a stripping system, with rack and pinion

or tilt-back

system.

 The formwork panels are adjusted of height with levelling jacks, and push-pull props to enable their

plumbing.

 Capability to adapt to complex wall geometries (inclined walls, curved walls

etc.)

 The working platforms provide a high level of safety

due to their ample space to carry out all

required construction works.

 Possibility to use two anchor types: DW15/M24 or DW20/M30.

The basic range of Climbing Brackets BMK is as follows:

 Climbing Bracket BMK-240

 Climbing Bracket BMK-170

1.1. CLIMBING BRACKET BMK-240

This bracket system offers 2 configurations or rather different assembly types: the mobile configuration with roll-

back carriage and the fixed configuration

with tilt-back system.

 Mobile configuration with Roll-Back Carriage: The formwork is joined to the main platform through the

Roll-Back Carriage (1991444) which is operated by a rack and pinion mechanism to separate the panels from the wall at stripping. A push-pull prop serves to plumb the formwork and the height adjustment of the panels is enabled by the Waler Screw TR53X6 (0302020) which connects the vertical waler to the Rollback carriage.

 Fixed configuration with Tilt-Back System:

The formwork is joined to the main platform through the TiltBack MK-120 (1991467). The panels can be separated from the poured concrete wall by a distance of about 5 cm. The Connector MK Screw Waler Base (1991517) enables the panel height adjustment by connecting the vertical waler to the stripping mechanism.

4. SOLUTIONS

Subsequently, the most common solutions with the climbing brackets BMK are described.

4.1. STRAIGHT WALLS

4.1.1. Straight walls with Roll-Back Carriage at both sides of the wall

In this configuration, the formwork of both wall sides is moved back to the maximum distance to ease steel reinforcement works.

CLIMBING BRACKET BMK-240 AT BOTH SIDES

The distance between wall and formwork is approximately 80 cm

but the exact distance depends on the formwork

type used (see section 2.2.1).

Page 56



 

BMK CLIMBING BRACKETS

4.1.2. Straight walls with Roll-Back Carriage at one side and Tilt_Back system at the other side of the wall

In these configurations only the formwork of one side of the wall is stripped with roll-back carriages because the steel reinforcement works can be done from this side. It is an easier and cost-saving alternative. At the side of the tilt-back system, the formwork can be separated from the wall by approximately 5 cm

and tilted by means of the

push-pull prop.

CLIMBING BRACKET BMK-240 and BMK-240 FRAME with Tilt-Back system In this configuration, the same BMK-240 Frames are used but at one side the frame is equipped with roll-back carriages and at the other it is equipped with the tilt-back system.

CLIMBING BRACKET BMK-240 and CLIMBING BRACKET BMK-170 In this case, additionally to the installation of the tilt-back system at one side, also the size of the working platform of this side is reduced by using the Climbing Bracket BMK-170. This configuration is even simpler and cheaper than the previous ones.



 

BMK CLIMBING BRACKETS

Straight perimeter walls with inside slab

In this configuration, the climbing bracket is only used at the outside of the wall because the inside formwork supports directly on the slab already built. Therefore, a working area between wall and outside formwork is not necessary. Instead the inside formwork is removed and the steel reinforcement works are carried out from the inside. For these cases, the adequate configuration is with the Climbing Bracket BMK-170.

4.2. INCLINED WALLS

For ±15º inclined wall solutions, the Hinged BMK-240 Bracket (1991465) is used. In these cases should be used beam formworks “ENKOFORM”.

For the cases that the angle between the horizontal and vertical beam is greater than 90º, the Push-Pull Prop TR63x6 2.04-2.2 (0333014) is used instead of Push-Pull Prop TR63x6 1.52-2.2 (1991514).

4.3. CURVED AND POLYGONAL WALLS

For solutions of curved and polygonal walls, the Fixed Head (1991410) is replaced by a special head with a particular angle for each application.

4.4. ANCHORAGE SOLUTIONS

The anchors are the tie members of the climbing bracket to the wall. It is of utmost importance to embed the anchors into the concrete as indicated in the assembly drawings in order to correctly transmit the loads from the structure to the concrete. The correct transmission of the anchor reactions to the concrete is responsibility of the customer. Only genuine components of ULMA may be used. Depending on the reactions in the anchors, DW20 or DW15 anchorages are used.

4.4.1. Drilling ORMA panel board

The shuttering face is drilled at the required position and dimension, d = 25 mm. Cone DW15/M24, tie rod DW15 and fixed anchor are placed on the shuttering face and fastened with the Cone-Waler Tie 90. The Tie passes through the gap between the vertical waler profiles MK-120 and is fastened with the plate nut of the tie.

4.4.2. Drilling ENKOFORM panel board

The shuttering face is drilled at the required position and dimension. The corresponding cone DW, tie rod and fixed anchor are assembled to each other, placed on the shuttering face and fastened with the climbing ring and the bolt from the other side of the board.



4.4.3. Without drilling the board

If drilling holes into the shuttering face shall be avoided, this is the way to proceed:

 The cone positioner is nailed to the board. Then the cone, the tie rod and the fixed anchor are assembled

to each other.

Page 67



 

BMK CLIMBING BRACKETS

 The formwork is removed from the concrete by reclining the panel. With the positioner spanner, the cone

positioner is removed from the cone

Special care has to be taken when tightening the bolts as well as the tie rods and the fixed anchors to ensure the effective transmission of loads from the structure to the concrete.

4.4.4. Installation and securing of climbing brackets

Once the last anchorage is fastened to the wall, the climbing structure is supported on the anchors. After having inserted the head into the climbing ring, the safety pin is placed and turned 90º thus clamping the climbing bracket against any accidental uplifting.

5. SYSTEM PROPERTIES

5.1. MAXIMUM SIZE OF FORMWORK PANEL

The system is designed to work under the following conditions:

Notes:

 The maximum wind load is 0.2 kN/m² which corresponds to a wind speed of 64 km/h.  For wind speeds above 64 km/h, all activities on the climbing structure are abandoned and the workers leave

the platforms. Moreover, it is necessary to move the formwork towards the wall and block the roll-back carriage with the Gear Locker MK (1991510) (see for details on page 16).

One limit of the climbing bracket BMK structure is relates to the maximum size of the formwork panel. In the below chart, the relation between panel height and width of the climbing bracket BMK-240 is shown. It is assumed that the length of the working platforms and the formwork panel width is the same. This chart is valid only for a working height below 100m.



5.2. LIMITS OF ANCHORAGES

For each application, the loads to be borne by the anchors must be analysed individually. These depend on the selfweight, the live loads and the wind loads. The anchor strength depends on the following factors:

 Concrete strength  Cone DW20/M30 or DW15/M24 strength  Tie rod DW20 or DW15 strength  Bolt M30 DIN-931-10.9 or M24 DIN-931-10.9 strength  Through anchor or with Fixed Anchor DW20  Embedded anchor depth  Edge effects

Therefore, the limit of the anchorage varies for each anchorage configuration, so each anchorage in particular must be studied.

6. TERMS AND CONDITIONS OF USE

The general terms and conditions of use can vary. Therefore, those are defined for each application in particular and included in the documentation for each project. Herein, serving as example only, the general terms and conditions of use are outlined.

6.1. LOAD CASES

The following load cases are identified for the climbing brackets BMK:  Working case:

when carrying out works such as concrete pouring, placing steel reinforcement, preparation and stripping. These works are restricted to a permissible wind speed of 64 km/h (0.2 kN/m2).

 Out-of-service case (OS):

when wind speeds are above the maximum permissible wind speed of 64 km/h (0.2 kN/m2).

When facing an out-of-service situation, the following preventive measures must be taken to ensure the safety of workers on the building site:  Evacuate all employees working on the climbing

bracket structure. Works must not continue on the climbing formwork.

 Tie any loose object of the climbing platforms.  In an out-of-service situation, the formwork panels

are moved against the wall and the stripping systems blocked.

6.2. MAXIMUM WORKING LOADS

According to the load case, some maximum load conditions are specified to which the system can be submitted. In each load case, permanent loads equal for all load cases and variable loads differing according to the load case are considered. Subsequently, the loads to consider are specified:  Permanent loads:

o Self-weight of the structure o Self-weight of the formwork panels o Self-weight of the working platforms

 Variable loads:

o Live loads on working platforms o Wind loads (according to Eurocode 1)

The final values are specified in the

documentation of each application.

Serving as example, these are the loads to consider.

BMK CLIMBING BRACKETS

6.3. ANCHORAGE STRENGTH

For each application, the loads acting on each anchor as well as the minimum strength which the concrete must have to hold the elevating structure are specified.

6.4. SAFE HANDLING GUIDELINES

6.4.1. BASIC SAFETY GUIDELINES ON SITE

 Appropriate certified personal protective

equipment must be used to ensure the safety of workers.

Always use:

o Safety helmet o Gloves o Safety boots

Where applicable and whenever necessary with

regard to the type of works carried out, use:

o Goggles or safety screens o Hearing protection o Breathing mask o Safety harness

 Adequate collective protection equipment (nets,

handrails, etc.) must be installed to ensure safe working at height.

 Observe an adequate tidiness and cleanliness of

formwork and climbing and formwork systems to ensure their safe handling. The working platforms are kept clean and tidy at all times, without tools, bolts and any other parts in danger of falling from them, and striking persons below.

 Toeboards are placed at the outside face of the

platforms to prevent objects from falling to a lower level. Moreover, safety nets can be installed at the outside face of the platforms to prevent objects from falling to a lower level. At the inside of the platforms cover gaps with rubber or similar material to prevent objects from falling to a lower level. Avoid working below platforms where work is carried out which might entail the hazard of falling objects.

 Access to and between platforms is ensured

exclusively by ladders installed for this purpose. After having accessed a platform, the ladder hatch must be closed. All ladders should project 1 m above the platform to which they provide access.

 Spread sawdust or sand on any slippery surface

caused by spilling (release agent, etc.).

6.4.2. System-specific safety instructions

 All persons responsible for the operation of the

climbing system must be qualified and trained and must have read the User's Guide before handling the system. The User's Guide should be constantly accessible for reference.

 In the case of doubt or lack of information, please

contact the Technical Department of ULMA.

 Travel sequences of the climbing system are carried

out under the supervision of the person in-charge of the installation. This person must be trained for the handling of climbing systems.

 The employed crane must be of sufficient capacity

for the handling and assembly of the climbing system parts.

 Check and verify all cables and slings. The

maximum angles between the slings during lifting may not exceed 60º.

 Strictly avoid the Lifting Hook MK suffering strong

blows and crushing from handling, storage and transport, and above all, from the handling of the formwork with it.

Page 72



 

BMK CLIMBING BRACKETS

 The Lifting Hook MK must be visually checked

before each use and removed from service, if not working properly.

 If the Lifting Hook MK experiences any sort of

deterioration during handling, it must be immediately removed from service.

 Before starting to lift the climbing brackets or

platforms, make arrangements to close the sides of the platform to avoid falls from height.

 No workers are allowed on the working platforms

during their lifting.

 Ensure a steady and smooth travel of the climbing

structure. Avoid any sudden jerky movements.

 Step back when lifting starts. Slightly lift the item

and check that the load is balanced and secured correctly.

 If not, lower the load again to the ground and

revise deficiencies.

 Stand clear of suspended load. Do not guide

suspended load with your hands. To guide suspended load, auxiliary means such as ropes previously tied to the load are used.

 Under the circumstances that the crane operator

has no visual control of the entire trajectory of the load, the crane operations are guided by a banksman who is in constant communication with the crane operator by means of a previously agreed sign code.

 To prevent collision between platforms or brackets

during elevation, special attention must be paid to the interferences between platforms and to any object which could interfere in the elevation movement of the system.

 The entire structure with its components must get

assembled according to the instructions and assembly drawings provided by ULMA. All bolts, connections, tie rods, pins, etc. must be assembled correctly.

 All working platforms of the climbing system are

kept free from ice and snow, even when not in use.

 The maximum permissible wind speed for working

on the climbing system is 64 km/h (0.2 kN/m

). The customer is responsible to check the wind speed at each lifting operation and to evacuate the platforms and to fix all platform components the way they do not fall down, when wind speed is rising.

 For correct handling of the climbing system, the

customer shall ensure at all times a minimum lighting of 100 lux in working areas, and particularly in areas where the cylinder operation is supervised.

 In the out-of-service case, all employees working

on the climbing bracket structure must leave the platforms. The formwork panels must be moved against the wall and the climbing brackets fixed.

 Before moving the roll-back carriages of the

climbing brackets, ensure that nobody remains between wall or steel reinforcement and formwork panel.

 The moving of the formwork panel towards the

wall must be carried out with special care. Moving the panels against the part of the concrete wall from the previous pouring stage, can cause a prestressing or overloading of the climbing system hence loading the climbing structure mainly the screw jacks but also the anchors.

 When moving the formwork panels against the

wall, it is very important to strictly follow the steps indicated below:

o Move the panel close to the wall (2-3 cm

from the wall) with the roll-back carriage.

o Plumb the formwork panel with the push-

pull prop.

Page 73



 

BMK CLIMBING BRACKETS

o Adjust the vertical position of the formwork

panel with the levelling jack located at the bottom of the vertical waler.

o Adjust the final position of the formwork

panel with the tie rods.

 The use of the climbing system and the presence of

persons on the system is forbidden when the weather forecast reports a storm with lightening.

 If the building site is located nearby high voltage

power lines, it is recommended to work without power supply. If this is not possible, the appropriate measures according to the respective reference standard should be taken.

 It is of utmost importance to embed the anchors

into the concrete as indicated in the User's Guide in order to correctly transmit the loads from the structure to the concrete. The correct transmission of the reactions in the anchors to the concrete is responsibility of the customer. Only genuine components of ULMA may be used to support and anchor the climbing system. ULMA cannot be held responsible for the use of material supplied by third parties.

 The live loads and maximum values of reactions in

the anchorages indicated in this guide must be respected. Likewise, the minimum concrete strengths indicated for the operation of the climbing system must be respected. The customer is responsible to control and check the concrete strength.

6.4.3. Maintenance of the climbing system

 Before assembling any system part, check that it is

in good working condition (rust, deformation, etc.).

 Periodically check the correct arrangement and

working of bolts, pins, wedges and joint components, in general.

 No alteration or change neither to the system

components nor to the assembly of the climbing system is made without the approval and under the supervision of ULMA personnel.

 All welding which affects the operation of the

climbing system are carried out under the supervision of personnel of ULMA.

 Proper storage of the parts is fundamental to keep

them in good working condition.

6.4.4. Inspection instructions of lifting

appliances with CE marking of ULMA Construcción

 Before each use, the condition of the lifting

appliance must be checked, confirming the good working condition of the following parts:
