MG - Modular Attenuators Basic Guidelines Cont. 2) Joining adjacent sections 1. Lay out and align the sections so that the external rails on each section are on the correct and matching faces (1). 2. Bring adjacent modules together, with the rails abutting. Use speedclamps or G-Clamps or similar as required to ensure a tight fit. 3. The Modular Joining Brackets (2) can then be fixed to the rails and to the flanges of adjacent modules using the supplied M8 countersunk allen screws (3). 4. Fixings are made through the brackets into nutserts in each of the mating rails on the adjacent attenuator modules. Two fixings are then made through the flange corner holes into the nutserts in the bracket. Each Modular Joining Bracket (2) incorporates slots for four fixings and nutserts for two fixings. This allows for fixings into the rails and through the flanges of adjacent modules as shown. Fix the screws loosely first until all fixings are in and the units have been correctly positioned and aligned. The screws should then be tightened. 3) Joining centre sections The views below give an enlarged view of a Modular Centre Joining Bracket in position. This bracket has a larger front face incorporating four nutserts to allow the joining through four separate attenuator module flanges. 4) Completing Once all of the sections are joined together, as shown in the view below, then a system of capping channel sections and pieces (1 and 2) can be fitted. These are used to close off the gaps between the flanges in the inner sections of the modular attenuator. 20 www.caice.co.uk CAICE Attenuator Brochure
EG - Splitter Element Attenuators For Installation within Apertures A set of splitter elements, constructed from galvanised sheet steel. Each splitter provided with bullnose aerodynamic fairings and expanded metal facings. Fibre glass tissue bonded to rear of facings to minimise infill fibre egress. For ease of handling splitters can be delivered, split in height or length, and quick fix joining brackets are then provided accordingly. Larger units may require supporting steelwork by others, depending on the application. Options available: 200, 250, 300, 350 or 400 wide centre splitters 100, 125, 150, 175 or 200 wide side splitters fitted with steel backing to enclose infill Vertical or horizontal splitter orientation Melinex wrapped infill Paint finish Integral inlet or outlet plenums on units with side splitters, by reducing length of centre splitters Fixing brackets for securing splitters into the aperture Available Aperture Widths and Heights: EG splitter element attenuators can be provided in 1mm increments within the aperture width and height ranges shown above, although 25mm increments are standard. Available Lengths: Element Orientation High Pressure Casings W1 min H1 min W1 max H1 max Vertical 250 250 100000 7000 Horizontal 250 250 7000 100000 Number of Delivery Sections in Length L1 1 450, 600, 750, 900, 1050, 1200, 1500, 1800, 2100, 2400 2 900, 1200, 1500, 1800, 2100, 2400, 3000, 3600, 4200, 4800 3 1350, 1800, 2250, 2700, 3150, 3600 4 1800, 2400, 3000, 3600, 4200, 4800 Standard lengths are shown in the table above, but where required EG splitter element attenuators can be provided in 1mm increments between 450 and 4800mm long. Splitter elements will be factory assembled up to a maximum size of 2200mm high by 2400mm long, unless requested otherwise. www.caice.co.uk CAICE Attenuator Brochure 21
