Question:

Code for construction of light steel keel ceiling

Do not know who can tell me ah

Answer:

Install the side keel The installation of the edge keel should be designed according to the requirements of the line, along the wall (column) on the horizontal keel line to L-shaped galvanized light steel strip with self-tapping Screws fixed on the embedded wood bricks; such as concrete walls (columns), can be fixed with nails, nail spacing should not be greater than the ceiling The spacing of the keel.
Set the hanging bar on the beam 1) Hanging rods should be straight and have sufficient carrying capacity. When the embedded bar need to take a long time, must be lap welding, Welds should be evenly full. 2) the length of the boom from the main keel shall not exceed 300mm, otherwise the boom should be increased. 3) ceiling lamps, tuyere and maintenance mouth should be set up additional boom.
Fixed hanging rod Fix the hanging rod with expansion bolts. Not on the ceiling, boom length less than 1000mm, you can use φ6 hanging Rod, if more than 1000mm, should be used φ8 boom, should also set the reverse support. The boom can be cold drawn And disk round bar, but the use of disk round steel should be used to straighten the machine. Master's ceiling, boom length less than 1000mm, You can use φ8 of the boom, if more than 1000mm, should be used in the user φ10 boom, should also set the reverse support. One end of the boom is welded with L30 × 30 × 3 angle code (the aperture of the corner code should be determined according to the diameter of the boom and expansion bolt) The other end can be tapped out with more than lOOmm screw, you can also buy finished screw welding. Make a good boom should do Rust treatment, boom with expansion bolts fixed to the floor, with the impact hammer drilling, aperture should be slightly larger than the expansion of the bolt diameter.
Install the main keel 1) The main keel should hang on the boom. The main keel spacing 900 ~ 1000mm. The main keel is divided into light steel keel and T-shaped dragon bone. Light steel keel can be used UC50 keel and UC38 keel. The main keel should be parallel to the room to the long installation, at the same time should be From arch, arch height for the room span of 1/200 ~ 1/300. The cantilever section of the main keel should not be greater than 300mm, otherwise Should increase the boom. The main keel should be docked, and the butt joints of the adjacent keels should be staggered from each other. The main keel hangs well After the basic leveling. 2) Span greater than 15m above the ceiling, should be in the main keel, every 15m plus a large keel, and vertical main keel Welded firmly. 3) If there is a large modeling ceiling, the shape part of the application of angle or flat steel welded into a frame, and should be connected with the floor firmly. (6) install the keel Times keel clear keel and dark keel two. Dark keel ceiling: that is, when the installation panel cover the keel will be closed in the shed, in the The roof surface can not see the keel. Ming keel ceiling: the installation of the panel when the keel exposed under the cover panel, in the ceiling The surface can see the keel. The keel should be close to the main keel. Times keel spacing 300 ~ 600mm. Times the keel points T-shaped paint keel, T-shaped aluminum alloy keel, and a variety of strip buckle manufacturers with a dedicated keel. T-shaped galvanized When the sub-keel is fixed to the main keel, the ends of the keel shall be seated on the horizontal flange of the L-shaped keel On the bar buckle plate has a dedicated angle to do the keel. (7) cover panel installation Hanging roof cover panels commonly used plate with sound-absorbing mineral wool board, silicon calcium board, plastic plate, grille and a variety of Kouban, etc.
Bears With the level of each wall in the room (column) angle out of the horizontal point (if the wall is longer, the middle is also appropriate to copy a few points) Pop-up line (level according to the ground is generally 500mm), from the level of the ceiling to the height of the design plus 12mm (a Layer of white plate thickness), with the powder line along the wall (column) pop-up line, that is, the tail of the keel down the skin line. Simultaneously, According to the ceiling plan, in the concrete roof pop-up main keel position. The main keel should be from the center of the ceiling to the two points, the largest Spacing of 1000mm, and marked the fixed point of the boom, the fixed point of the boom spacing 900 ~ 1000mm. Such as encountering beams and tubes The fixed point of the road is greater than the design and procedure requirements, and the fixed point of the boom should be increased.
