Light steel keel paper gypsum board partition wall construction, vertical keel spacing for how much
1, fastening material: nail, expansion bolts, galvanized self-tapping screws (12mm thick gypsum board with 25mm long
Screws, two layers of 12mm thick gypsum board with 35mm long screws), wood screws, etc., should meet the design requirements. 2, filling materials: glass wool, mineral wool board, rock wool board, according to the design requirements.
3, gypsum board: gypsum board should be a product certificate. Specifications should meet the requirements of the design drawings. 4, seams material: seam putty, fiberglass belt (cloth), 107 glue.
5, the main machine: plate saw, electric scissors, electric self-drilling, electric toothless saw, hand drill, nail gun, DC welding machine, scraper, line fall, by the foot and so on.
Light steel keel: the current wall works using light steel keel mainly support card series keel and through the series keel. Light steel keel main pieces along the top along the keel, strengthen the keel, vertical (horizontal) to the keel, cross the keel. Light steel keel accessories have support cards, Cato, angle care, connectors, fixtures, corners, pressure joints and so on. Light steel keel configuration should meet the design requirements. Keel should have product quality certificate. Keel appearance should be flat surface, angular straight, transition angle and trimming do not allow cracks and burrs, the surface shall not have serious pollution, corrosion and mechanical damage.
The distance between the main keel and the main keel can not exceed 1.2m, if more than this distance, and should try to do reinforcement treatment; vice keel and vice keel spacing between 30cm, gypsum board thickness of 9.5mm. If the thickness of the gypsum board is 12mm, the distance between the vice keel can be enlarged to 40cm. But in the actual construction, the vice keel spacing is 30cm, basically no one made 40cm.
