The sound-absorbing ceiling gypsum board is economical and reasonable to reduce waste. Compared with the ordinary brick concrete secondary structure wall, it has the external wall construction and installation method of avoiding chiseling

sound-absorbing ceiling gypsum board 1200*2400mm

composite rock wool board caused by water and electricity reservation and embedding. Composite rock wool board is a new generation of thermal insulation material composed of hydrophobic rock wool board and fireproof glass magnesium board. It is cut into rock wool strips, and then the two sides of the rock wool strips are plastered with glass magnesium board glue after splicing, and reinforced with glass fiber mesh cloth. Rock wool composite board is mainly used in external wall thermal insulation, ceiling roof thermal insulation, non transparent curtain wall, etc. it can also be used in EPS fire isolation belt. Rock wool composite board, also known as A-level composite rock wool board, cement faced rock wool board and vertical wire rock wool composite board, is a new generation of A-level non combustible insulation material introduced after the Ministry of Public Security issued document No. 46. External wall construction and installation method of composite rock wool board. Composite rock wool board is a new generation of thermal insulation material composed of hydrophobic rock wool board and fire-proof glass magnesium board. It is cut into rock wool strips, and then the rock wool strips are spliced, plastered with glass magnesium board glue on both sides, and reinforced with glass fiber mesh cloth. Rock wool composite board is mainly used for external wall insulation, ceiling roof insulation

some minor problems of gypsum board partition wall

gypsum board partition construction should meet the following requirements: 1 When the distribution box, socket, through wall pipe and other devices are set in the partition wall, the surrounding gaps should be effectively sealed. 2. If the horizontal joint is not on the keel along the side, a horizontal keel should be added to fix the gypsum board. 3. The upper faces on both sides of the door shall not be through welded, but L-shaped plates shall be adopted to make it staggered installation

construction process: 1 Paste the cement rock wool board directly on the plastering layer of the external wall with special mortar. 2. Apply anti crack mortar outside and press the anti alkali mesh cloth into the polymer mortar. 3. Fix it with heat preservation nails, and the number of heat preservation nails is not less than 9 per square meter. 4. Apply the second anti crack mortar plastering and press the anti alkali mesh cloth into the anti crack mortar again. The door window, hole opening, plinth and other parts are smoothed with perlite heat preservation particles and inverted wrapped with anti alkali mesh cloth, Scratch anti crack mortar outside

features:

effectively adjust the indoor reverberation time, adjust the sound effect, and improve the sound quality

effectively absorb sound energy and reduce noise

dry operation, convenient construction, light weight and environmental protection

construction process: snap the ceiling horizontal line - install the main keel - install the secondary keel - brush anti rust paint - install gypsum board - finish cleaning 1. Snap the ceiling horizontal line: snap the ceiling elevation horizontal line around the wall according to the design elevation, and draw the keel grading position line on the wall along the ceiling elevation horizontal line. 2. Install the main keel suspender: after snapping the ceiling elevation horizontal line and dragon position line, determine the elevation of the lower end of the suspender and install the suspender. The straight installation is fixed to the structural ceiling with expansion bolts. The selected specification of the suspender meets the design requirements, and the spacing is less than 1200mm. 3. Install the main keel: stick the top main keel every 1 meter Φ The expansion bolts above 8 mm can be fixed, and other points can be fixed with iron nails and wooden wedges. The main keel along the wall shall be fixed with iron nails and wooden wedges, and the spacing between the main keels shall not be greater than 400 mm. The distance between main dragons is 900~1200mm. The main keel is connected with the suspender with the matching dragon hanger. 4. Install the secondary keel: install two full-length side keels according to the position of the dividing line and the main keel, draw a line to confirm that it conforms to the horizontal elevation, and use the vertical hanging small keel to fix the connection between the side keel and the main keel. The vertical hanging small keel should be one by one
