Track-guided, sound-insulating operable partition, type: DORMA MOVEO – ComforTronic Product description: Operable partition comprising individual panel elements of closed composite construction with light and stable outer shell in sandwich technology with surrounding frame assembly and core of acoustic foam, for independent manual operation. In order to ensure efficient sealing of the elements at the floor and ceiling track, all horizontal element seals must be actuated and controlled by the ComforTronic system, i.e. extend and retract in positional sequence under automatic (electrically powered) control. A self-supporting, torsion ally stiff construction shall be provided and verified to ensure the durable functional efficiency of the partition (element interconnection and sound insulation). In order to ensure minimal transmission of structure-borne sound, the frame profiles shall exhibit all-round flexible secondary profiles for acoustic isolation. In order to allow the load-bearing structural components of the recipient building to be dimensioned against flexion in an appropriate, cost-efficient manner, the specific weight per unit area of each element shall not exceed 40 kg/m2 for a sound insulation value of Rw = 55 dB, 26 kg/m2 for Rw = 47 dB, and 18 kg/m2 for Rw = 37 dB. Partition constructions exhibiting higher unit weights are therefore not permitted. The lower weight of the panel elements ensures that they are exceptionally easy to operate. The element thickness shall not exceed 100 mm. The extending double-chamber seals shall exhibit a black finish. The sound insulation must satisfy requirements commensurate with the building project usage profile. Functional description: Automatic element locking system To facilitate speedy opening and closing of the partition, the horizontal seals (sealing strips) of the individual elements and the telescopic element must be extended and retracted automatically under control of the ComforTronic system. The power supply shall be conducted from element to element via end-face contacts. The electrical power supply to the actuating and control system shall be provided via a plug-in power supply unit. The seal retracting mechanism shall be controlled by a central switch. All the partition functions shall be monitored by a microprocessor. In order to ensure functional efficiency, even in the event of a malfunction or fault (power failure), a mechanical emergency unlocking device shall be provided for all elements. The elements must feature spring-loaded double-chamber seals top and bottom that are pressed against the ceiling track profile and the floor, compensating for floor unevenness through permanent spring load application. In order to ensure optimum vertical sealing between the extended sealing strips, flush-aligned sealing strip end elements must be provided in the form of polyurethane mouldings. The material of the sealing strips shall be high-strength aluminium capable of meeting the highest requirements in terms of sound attenuation and stability. To enable compensation for any structural tolerances in the floor and ceiling, the extension stroke of the sealing strips top and bottom must in each case be at least 30 mm. Sliding-contact rubber seals are not permitted. Element interconnection Achieved by the combined positive and non-positive interlocking of aluminium profiles. Resistance-free interconnection of the profiles is ensured by their convex/concave profiles. Additional flexible seals are provided in the element joint. Telescopic element The partition end closure element in each case must be of overlapping, compensating telescopic design. The extensible compensating panel shall be of the same material as the partition. Pass door elements Pass door or double pass door elements are to be equipped with a surrounding, self-supporting portal frame and constructed as stress- and constraint-free assemblies. The lateral posts must be provided with a compression beam for reliable, positive engagement with the floor. Post stability shall be further enhanced by locking projections that engage in flush-recessed floor sockets. The door leaf must be provided with a frame and an automatically operable sealing strip. The sealing components that engage flexibly with the ceiling (sealing strip) and floor (sealing feet in the door posts) must be electrically operable. Requirements for additional means to ensure the stable location/positional locking or for electrical operation of the door are not permissible. In the case of double pass doors, one leaf should be equipped to function as the active leaf and one as the inactive leaf with emergency unlocking function. Element suspension, track system, stacking (parking) arrangement Each element must be hung at one or two points from a ceiling-mounted track of aluminium and operate on multi-roller carriers featuring track rollers mounted in ball bearings. The carriers must be secured to the element by means of horizontal ball bearings engaging with the shock-absorbing (damped) roller pin on the element. Owing to their elevated wear values, assemblies comprising ball-mounted or sliding discs are not permissible. To allow for minor structural sag in the ceiling, the elements must be designed for easy height adjustment without the need to open up either the ceiling or the element. An aluminium track rail shall be installed to ensure easy, low-noise operation of the elements. Additional track cladding must not be necessary. It shall be possible to implement all right-angled and positive-guidance stacking track assemblies with this track design. In order to ensure that the partition functions with maximum efficiency, the following criteria must be satisfied: It must be possible to compensate for subsequent, more serious structural ceiling sag through easy partition height adjustability. The track assemblies up to the load-bearing structure shall be fixed by means of adjustable steel suspension assemblies. These shall be provided by the bidder and attached to appropriate load-bearing structural components (e.g steel substructures, concrete beams etc.). Rigid, non-adjustable suspension assemblies are not permitted. The materials employed must be non-corroding or corrosion-protected. The partition systems offered shall exclusively feature track constructions and suspension assemblies in the form of “simple steel structures” as per DIN 18000-7 (see also VOB [Construction Contract Procedures], Part C, DIN 18335). According to State Building Regulations, the bidder shall possess a certificate of welding competence (e.g. to DIN 18000-7 – Certificate of competence for the welding of simple steel structures subjected to predominantly static loading). A double-skin sound baffle (attenuation up to Rw = 47 dB) or a quad-skin sound baffle (Rw = 55 dB) must be installed above the track assemblies by the bidder to correspond to the specified sound reduction value of the partition elements. A clean, tight baffle seal against the track and adjacent building parts must be ensured. The gaps between the baffle skins must be filled with non-settling mineral wool. The ceiling joints must be sealed with silicone mastic filler (permanently elastic type). The above assemblies/subassemblies, fills and baffle systems must be included in the unit prices. A valid test certificate to EN 20 140-3: 1995 must be presented validating the sound insulation performance of the operable partition.. The measurements shall be performed on a wall test facility to EN ISO 140-1: 1998. Calculation of the weighted sound attenuation value and of the spectrum adaptation terms shall be compliant with EN ISO 717-1: 1997. Compliance of the operable partition with the ball rebound test to DIN 18032 Part 3, August 1997 edition, must likewise be verified by an appropriate certificate. A valid test certificate to EN 1634-3 must be presented validating the smoke denseness of the operable partition. General ISO Quality Management Certificate The manufacturer of the partition system must have introduced a quality management system to EN ISO 9001 and be registered to this standard. This must be verified by presentation of an appropriate certificate. Certificate registration no.: ............................. valid until .................
