Abstract

The invention discloses a preparation method of a sound insulation combined door casing with few gaps. The door casing comprises a first door casing, a second door casing and a third door casing. An obtuse-angle notch is formed in the bottom end of the first door casing, tenons are arranged on the edge of the obtuse-angle notch, flanges matched with the obtuse-angle notch in the first door casingare arranged at the top end of the second door casing and the top end of the third door casing, mortises are formed in the edges of the flanges, and the tenons are inserted into the corresponding mortises. Before the tenons are inserted into the corresponding mortises, the interiors of the mortises are coated with sound insulation sealant, and after the tenons are inserted, the joints of the firstdoor casing, the second door casing and the third door casing are coated with the sound insulation sealant. According to the invention, the sound insulation combined door casing with the few gaps hasthe advantages of being high in installation speed and excellent in sound insulation effect.

Description

technical field [0001] The invention belongs to the technical field of wooden door material preparation, and in particular relates to a preparation method of a sound-insulating composite door cover line with few gaps. Background technique [0002] The door cover line is a soft decorative line that wraps the wall, which is the bead, clip, and other parts of the door cover. The main production materials are plastic steel, polymer, wood plastic, density board, log, gypsum, magnesium aluminum alloy, marble and so on. Plastic-steel and wood-plastic door cover lines are widely used, and the surface processing is divided into various methods such as film coating, transfer printing and baking varnish. [0003] The assembly method of the door cover line is: put the assembled door cover line into the door opening, the back of the door cover line is on the same parallel plane as the door opening, fix it with wooden wedges from the left and right sides of the door opening, and check it...
