Light steel keel and wood keel the difference
Light steel keel advantage is not easy to deformation, the disadvantage is to do modeling difficult;
The advantages of wood keel is easy to do all kinds of modeling, the shortcomings are easy to crack.
Top construction method, classification, comparison:
Wood keel ceiling:
Wood keel is easier to do local shape, keel brush fire paint twice, keel with nails or nail fixed, each with two nails fixed, made 300 * 300 or 400 * 400 frame, Adjust the low, straight, after the acceptance of gypsum board, the use of self-tapping fixed, self-tapping density: 20cm, the edge part of the density should be some.
Wood keel and light keel combination:
Do not recommend this practice, the individual feel better than the complete wooden keel or completely light keel production of strong. And the construction time is relatively troublesome.
Completely use light keel:
Light steel keel is not easy to do local shape, the use of expansion screws, d nails, etc., to install more solid. Light Gang keel with fire, not easy to deformation, strong and so on, is currently widely used method. Whether it is a large area of ??the ceiling or local ceiling can use this method of construction.
Ceiling Note:
Top, the keel of the wall should be fixed with a wooden wedge, nail, or with an expansion bolt. Do not use spikes (easy to fall).
When the gypsum board is installed, the gypsum board seams are staggered from the keel frame.
Fixed gypsum board: the use of self-tapping fixed, do not agree with the use of spikes (nail many, small, easy to brush anti-rust paint).
Light steel keel is good, will not be damp, will not be deformed, but not easy to do modeling, so there are a lot of home improvement with wood keel, because it is easy to do a variety of shapes, but to brush on the moisture and fire paint. Can be used with white pine
