Coop MK SYSTEM 5 Product description 6 Applications 20 System components and accessories 27 ULMA Construcción in the World 4 MK SYSTEM u u u u u u u u u u 5 MK SYSTEM Applications MK Structures All those structure which require high load capacity can be configured by connecting MK walers. The combination of the MK Structure system with other shoring and traveller systems increases the number of possible solutions: MK TRUSS Support structure for ENKOFORM HMK formwork in large span applications. It is easy to adapt to and to reinforce according to the particular building site requirements. u Powerful shoring for special buildings u MK Truss shoring up bridge MK FORM CARRIERS Deck flange form carrier Instead of a customised structure for steel-concrete composite bridge decks, the standard solution offered by MK Form Carrier increases the cost-effectiveness of projects. The forward-moving of the form carrier is easy with the pull or push auxiliary devices recommended by ULMA. u Construction of upper slab and wings of steel -concrete composite bridge u Deck flange form carrier in concrete bridge 6 MK SYSTEM Parapet form carrier Light form carrier which can be moved manually. It is used for applications with lower load-bearing and forward-moving requirements. It only requires a solid base where to rest the guide rail on. This system is the appropriate for the construction of bridge protection parapets. u u Parapet form carrier in between two bridge decks u Example of parapet form carrier CVS Cantilever carriage The MK System in its configuration of a cantilever form carriage eases the construction of pier segments with balanced cantilevers as well as straight or curved decks of constant or variable section, and bridge arches. u u Construction of bridge with balanced cantilevers 7 MK SYSTEM Vertical formwork carrier By fixing the formwork onto this carrier, it eases and simplifies the formwork erection and stripping works and the travel of the formwork to the next pouring stage in the construction of single- or double-sided concrete walls. u u Vertical formwork carrier for double-sided walls Vertical formwork carrier for single-sided walls Tunnel form carrier The solution with the MK System for tunnels can be considered another type of form carrier adapted to the particular requirements of tunnel construction. It effectively combines the shoring and the form-giving of the formwork which has to adapt to the vault shape of the tunnel. u Any required geometry is formed with the available standard items u Cut-and-cover tunnel with electric rolling system 8 MK SYSTEM Formwork systems ENKOFORM HMK With beams and standard walers, the horizontal formwork ENKOFORM HMK allows adapting to the varied shapes of concrete structures in civil engineering. With this system, it is possible to form the varied sections of bridge decks, overpasses and underpasses, and any other application that requires high load capacity. Typology of works with ENKOFORM HMK: u Bridge sections, viaducts, overpasses and other, with constant or variable section in u ENKOFORM HMK in the construction of a bridge deck width and depth u Slabs of great thickness u Underpasses u Pier caps u Pier segments u Combination of ENKOFORM HMK and T-60 Shoring System benefits u u ENKOFORM HMK in pier caps and bridge decks The connector design enables perfect adjustment and adaptation to the different sections of: Bridges of constant or variable section, both solid and hollow Bridges of variable deck depth, solid or hollow Bridges with superelevation Rigid structure for handling and transport. Fast stripping by modules or formwork units. Easy jointing of walers and timber beams. 9 MK SYSTEM ENKOFORM VMK It provides great performance and excellent finishes as vertical formwork in any application of building construction and civil works: walls, columns, abutments and piers. In accordance to the requirements of each project, it is possible to make customised panels consisting of steel walers, timber beams and phenol faced plywood. System benefits It provides excellent finishes capable of suiting the Reduced transport volume if the material is delivered requirements of surface designs predefined by the architect. dismantled to the building site. The formwork can be optimised according to the defined Panel joints are simple and adjustable. The requirement concrete pressure. for filling elements is minimal. Panels with standard plywood, easy to be replaced, allowing the reuse of panels. The Panel Connector ensures the hermetical longitudinal joint between panels. In addition, it conducts a corrective Using common standard accessories of other ULMA function by absorbing possible deviations occurring during vertical formwork systems as stabilisers, climbing brackets, assembly. anchors, etc. u Columns with ENKOFORM VMK u u On-site assembly of ENKOFORM VMK panels Wall construction 10 MK SYSTEM u Silo solution with ENKOFORM VMK curved formwork on climbing structure Applications ENKOFORM VMK offers solutions for numerous vertical concrete geometries: 1 Columns 2 Embedded column - 90º wall intersections 3 Corners at 90º 4 Bulkheads 5 Fillers 6 Beam VM20 Connection Plate 7 Working bracket 10 8 Lifting 9 Stabilisation 10 Curved panels 8 3 1 7 9 6 5 2 4 11 MK SYSTEM MK Shoring Systems With the MK system, it is possible to configure different load support structures in the field of civil engineering.

Possibility to assemble independent towers or entire shoring structures. Independent jacks give solution to superelevations. Easy and secure joints between components. Anchoring of the tower base increases the permissible u Connection between components load capacity. Different stripping options, at base or head. Erection of wind bracing systems between towers to provide optimum solutions. Wide range of safety items such as platforms, handrails and ladders that can be installed at any point of the tower. u Anchorage of the base of the towers u u u Stripping with hydraulic jack at Stripping with wedge at base Stripping with jacks at head base and head and head u Shoring with MK props of prefabricated beams u Shoring of vehicle passageway u Working platforms and handrails on top of the tower in abutment 13 MK SYSTEM MK Climbing Systems CONVENTIONAL CLIMBING SYSTEMS These are formwork support systems which make the construction in stages of high-rise repetitive buildings more cost-effective. System benefits Compatible with ULMA formwork, both modular as well as beam-based. In a single crane movement - entire sets of climbing brackets and formwork panels are moved to the next pouring stage. Easy adaptation to different geometries: straight, inclined and circular walls. Availability of working platforms at different levels with protection equipment for front and lateral safety and access ladders between platforms. Possibility to bridge gaps in the wall. All climbing brackets incorporate connections for handrails, adjustable push-pull props and other accessory. Possibility of formwork stripping with roll-back carriages. Adjustment, positioning and plumbing of formwork is done with levelling jacks and push-pull props. u Climbing systems in construction of piers Climbing bracket anchoring to the wall with cone-and- climbing ring system. MK Climbing Brackets The MK Climbing Brackets consisting of standard MK Walers and specific accessory can be adapted to include solutions for sloping and circular walls. As the brackets are assembled out of independent walers fastened with bolts, they can also be dismantled for the purpose of saving transport costs.
