First, the material description:
Wooden sound-absorbing panels adopt advanced technologies at home and abroad, apply the latest acoustic theory, have obvious acoustic effects, are simple and convenient to install, and meet environmental protection requirements. They have been widely used in domestic new building decoration projects.
1. Wooden sound-absorbing panels consist of facings, core materials and sound-absorbing mats. The core material is a 16mm or 18mm thick imported MDF sheet. The front surface of the core material is affixed with a decorative surface and the back of the German Freudenberg black acoustical felt. According to the customer's request, the finishes include various wood veneers, imported paint surfaces, paint surfaces and other finishes.
2. Keel (1) The wall surface covered by sound-absorbing panels must be installed with the keel according to the requirements of design drawings or construction drawings, and the keel should be leveled. Keel surface should be smooth, smooth, no rust, no deformation.
(2) The structural wall shall be pre-processed according to the building code. The keel arrangement must be adapted to the sound-absorbing panel arrangement. The spacing of wooden keel should be less than 300mm, and the spacing of light steel keel should not be more than 400mm. The keel should be installed perpendicular to the length of the acoustic panel.
(3) The distance from the surface of the wood keel to the base layer is generally 50mm according to the specific requirements. The degree of flatness and verticality of the wood keel edge should not exceed 0.5mm.
(4) If fillers are required in the keel clearance, they should be installed and handled first according to the design requirements, and they must not affect the installation of sound-absorbing panels.
Second, install:
1. Measure the dimensions of the wall, confirm the installation position, determine the horizontal and vertical lines, and determine the cut-out dimensions of the wire socket, pipe, and other objects.
2, according to the actual size of the construction site to calculate and cut part of the sound-absorbing panels (symmetrical requirements on the opposite surface, in particular, pay attention to cut some of the size of the sound-absorbing panels to ensure both sides of the symmetry) and lines (edge ​​lines, corner lines, connections Lines), and reserved for wire sockets, pipes and other objects.
3, install the sound-absorbing board:
(1) The installation order of sound-absorbing panels follows the principles from left to right and from bottom to top.
(2) When the sound-absorbing panel is installed laterally, the notch faces upward; when installed vertically, the notch is on the right side.
(3) Some solid wood sound-absorbing panels have requirements for pattern, and each facade should be installed from small to large in accordance with the pre-programmed numbers on the sound-absorbing panels. (Numbers of sound-absorbing panels follow from left to right, bottom to top, and numbers from small to large)
4, sound-absorbing board fixed on the keel:
(1) Wooden keel: The sound-absorbing plate is fixed on the keel by nails along the groove and plate groove. The shot nail must have more than 2/3 embedding wood keel, and the shot nail should be evenly arranged. At a certain density, the number of nails per acoustic panel and each keel is not less than 10.
(2) Light steel keel: Use a special installation accessory sound-absorbing panel to install transversely, with the notch facing up and installed with mounting accessories. Each sound-absorbing panel is connected in turn. The sound-absorbing panel is installed vertically with the notches on the right side, and the same method is installed from the left. The two sound-absorbing board ends should have a gap of not less than 3mm.
5. When there is a requirement for the sound absorbing board to be edging, it can be closed by the number 580 for the edge and the edge is screwed. When the right side and the upper side line are installed, it is set to 1.5mm for lateral expansion and can be sealed with silicone.
6. There are two methods for installing sound-absorbing panels at the corners of the wall, which are closely matched or fixed by 588 lines.
(1) Interior corners (inset angles), close together; fixed with 588 lines;
(2) External corner (positive angle), close together; fixed with 588 lines.
7, manholes and other construction issues (1) inspection holes in the same plane, manhole cover in addition to the other side of the wooden edge of the sound-absorbing panels to be decorated; the wall of sound-absorbing panels in the inspection hole at the edge, Only need to be flush with the manhole edge.
(2) If the position of the access hole is in vertical contact with the wall surface of the sound-absorbing panel, the position of the access hole shall be changed to ensure the construction conditions of the sound-absorbing panel.
(3) If other construction problems (such as wire sockets, etc.) are encountered during installation, the connection method should follow the requirements of the designer or follow the instructions of the on-site technical personnel. For other special situations of the construction site, please communicate with the technical personnel of our company in advance.
8, sound-absorbing panels installed in the door, window and other openings.
Third, note:
1, paint color (1) solid wood veneer sound-absorbing board color, is a natural phenomenon.
(2) There may be a color difference between the paint finish of the sound-absorbing panel and other parts of the installation site. In order to maintain the consistent color of the paint, it is recommended to adjust the color of the hand paint on other parts of the installation site according to the pre-painting color of the sound-absorbing panel after installation of the sound-absorbing board; or to request the company to provide sound-absorbing boards with solid wood finish without pre-painting treatment. .
2. Wooden sound-absorbing panels must be sealed against moisture in the non-installation environment.
Fourth, quality assurance: wooden sound-absorbing panels of technical and quality indicators in line with national standards. The warranty period is one year. During the warranty period, the quality problems of the products provided under normal use are free of charge. Life-long service after the warranty period.
