Construction Process of Light Steel Longguard Paving
Keel installation
1) large keel available welding method and hanging rod welding. But it is best to use the hanging rod and the boom connection, tighten the screw card. Large keel can be connected with a long connection. After installation to be leveling, consider the height of the ceiling from the arch, not less than the room short span of 1/200.
2) in the keel with a hanging piece with a large keel fixed. The spacing of the keel depends on the size of the plate. When the spacing is greater than 800 mm, the keel should be added between the keel, which should be parallel with the keel, and hanging with a large keel and fixed, the lower surface and the keel at the same level.
3) in the seam joints should be installed in the cross, the keel, cross-keel with a flat connection with the small keel fixed.
4) the final installation of special-shaped roof or curtain box shaped keel or teach aluminum keel.
Installation process
1, operating conditions
Light steel keel gypsum board ceiling installation of the operating conditions with the "wooden ceiling."
2, material preparation
According to the design requirements, choose the appropriate U-shaped keel series, and according to the actual plane size prepared keel main parts and accessories.
Cover panel varieties, specifications should meet the design requirements.
3, equipment to prepare
Light steel keel gypsum board installation and construction of the machine with the "light steel keel gypsum board partition wall."
4, operating procedures
Spinning line → fixed boom → installation of the big keel → by the elevation of the adjustment of the big keel → large keel bottom of the ball line (pull line) → fixed, small keel → installation of plaster board → gypsum plaster surface → clean The
Construction points
(1) according to the design of the ceiling height on the wall line, the level of tolerance ± 5 mm.
(2) boom installation
1) choice of boom. Generally speaking, light steel keel ceiling selection of the boom can be based on the standard map, light steel ceiling selection diameter 6, medium, heavy selection of diameter 8. If the design has special requirements, the load is large, you need to be determined by structural design and verification.
2) According to the design or standard map to determine the hanging point spacing. Generally not on the ceiling between the 1200 ~ 1500 mm, the ceiling distance of 900 ~ 1200 mm.
3) fixed ceiling. For the cast-in-place concrete roof can be embedded in the construction of embedded boom or embedded iron, so that the boom and iron welding. In the old building or concrete orifice can be used under the nail gun hanging point iron (small angle iron) fixed, need to add a gasket. The nail must be secure (if the nail is perforated, the boom can be used to fix the boom). Or the expansion bolt under the lifting point.
4) When the boom is installed, the upper end should be welded with the embedded piece, the lower end should be set with thread, with a good nut, the end of the thread exposed to not less than 3MM.
