the sound absorbing board.
Posted: Fri Aug 04, 2017 1:18 am<p>no rust, no deformation. 2, structural walls should be in accordance with construction specifications before construction, the keel layout must be compatible with the layout of the sound absorbing board. Wooden keel spacing should be less than 300mm, light steel keel spacing is not greater than 400mm. The keel shall be installed perpendicular to the length of the sound absorbing board. 3, wooden keel </p>
<p>surface to the grass-roots distance, in accordance with specific requirements, generally 50mm. Long bone side surface flatness and verticality error should be less than 0.5mm. 4, keel gap need filler, should be installed according to design requirements, processing, and ensure that does not affect the sound barrier plate installation. Two �� wooden sound absorption board installation 1, measuring wall size, </p>
<p>confirm the installation position, determine the horizontal and vertical lines, determine the wire, socket, pipe and other objects empty cut aside size. 2, according to the construction site of the actual size calculation and cut part (sound-absorbing board opposite symmetry requirements, with particular attention to cut part of the sound absorption plate size, guarantee on both sides of the symmetrical) and lines </p>
