How to calculate the primary and secondary keels of the integrated ceiling, and how far is the dista

The main keel and the triangular keel are priced on a root-by-root basis, with a fixed length for each one, and then cut according to the size of the environment in actual use.

The maximum distance between the main keel and the main keel can not be exceeded, if this distance is exceeded, efforts should be made to reinforce; The spacing between the auxiliary keel and the auxiliary keel is 30cm, and the thickness of the plasterboard is. If the thickness of the plasterboard is 12mm, the spacing between the auxiliary keels can be enlarged to 40cm. But in the actual construction, the spacing of the auxiliary keel is 30cm, and basically no one makes it 40cm.

You give me the drawings and I'll help you draw the main dragon with one square meter or generally with a spacing of about one meter 5 square meters of room with three sections of the main dragon 6 internal expansion suspension points The spacing of the triangular keel is according to the size of the board How big the board is as wide as the spacing.

No matter how big the plate is, the distance between the main keel is no more than one meter two, and the secondary keel looks at the board, and the board is as wide as it is.

The spacing of the wooden keel in the ceiling:

1. Light steel keel: wooden keel as a side dragon, the position of the light trough is made of wooden keel or woodworking board, and the wood production place must be brushed with fireproof coating, the keel is at least 50 or more, the spacing is 30cm, the spacing of the suspension bar is 60-80cm, the gypsum board and the board should be artificially reserved for 5-8 mm gap, the gypsum board surface self-tapping screw is inverted 1-2mm and anti-embroidery treatment, it is necessary to be smooth and firm, and the special-shaped lines should be smooth;

2. Wooden keel: keel at least 3 4 or more, the spacing of 30cm is appropriate, the spacing of the suspension bar is 60-80cm, the suspension bar is strictly forbidden to directly use the wooden wedge nail to the top, brush the strict fireproof coating until the color of the wooden keel is not visible, the keel is covered with a full layer of willow eucalyptus core nine centi board and then on the gypsum board, between the gypsum board and the board to artificially reserve a 5-8mm gap, gypsum board surface self-tapping screw invagination 1-2mm and do anti-embroidery treatment, to be smooth and firm, special-shaped to achieve smooth lines;

3. Aluminum buckle plate: strict requirements for level, light steel keel bayonet teeth should be aligned, keel spacing within 50, hanging bar spacing 60-80 cm is appropriate, hand should be light when on the board, so as not to press the board surface out of the pit, the edge strip and the tile contact is not tight to be tightly beaten with sealant;

4. Aluminum-plastic panel: wood keel at least 3 4 or more, spacing 30 cm is appropriate, hanging bar spacing 60-80cm is appropriate, brush strict fireproof coating, keel on a layer of full-foot willow eucalyptus core nine centimeter board and then paste aluminum-plastic board with universal glue, between the aluminum-plastic board and the board to artificially reserve 3-4mm gap, has been prepared to fill other colors to play the effect of the grid, to be smooth and firm, special-shaped to achieve smooth lines, the corners of the folding surface to be smooth and not broken.

How to calculate the primary and secondary keels of the integrated ceiling, and how far is the distance between the keel and the keel

The main keel spacing standard is between 80 cm and 120 cm, and the specific needs to be decided according to the thickness of the ceiling, such as using a relatively thick gypsum board, then the spacing of the main keel should be smaller, so that the load-bearing capacity will be better, on the contrary, if the ceiling is relatively light and thin, then the spacing of the main keel can be appropriately adjusted, but it should be noted that the maximum can not exceed 120 cm.
