An easily disassembled and sound-insulated composite wooden door

Abstract

The invention discloses a combined wooden door easy to detach and capable of insulating sound. The problem that a combined wooden door in the prior art is not easy to detach is solved. The combined wooden door comprises two border vertical plates. A middle cap plate is connected between the two border vertical plates. An upper cap plate and a lower cap plate are arranged above and below the middle cap plate respectively, two upper core plates symmetric front and back are arranged between the upper cap plate and the middle cap plate, and two lower core plates symmetric front and back are arranged between the lower cap plate and the middle cap plate. A sound insulating plate is arranged between the two upper core plates, and a sound insulating plate is also arranged between the two lower core plates. The combined wooden door is characterized in that the two vertical borders, the upper cap plate and the lower cap plate are all U-shaped groove clamping plates, the inner side of one of two parallel sides of each U-shaped groove is in a wedge shape, and a groove is formed in the inner side of the other of the two parallel sides of each U-shaped groove. The combined wooden door further comprises wedge-shaped blocks matched with the wedge shapes on the inner walls of the U-shaped grooves. Elastic matter is arranged in the grooves, and the thickness of the elastic matter is larger than the depth of the grooves. In the detaching process, a combined door sheet can be detached from the U-shaped grooves without any effort.

Description

technical field [0001] The present invention relates to the field of doors. Background technique [0002] Existing sound-proof wooden doors are generally provided with sound-absorbing boards between two or more layers of wood to achieve the effect of sound insulation. Glue is required between the sound-absorbing boards and the two-layer wood boards to ensure the overall structural stability of the wooden door; but such Wooden doors need to use a lot of glue, formaldehyde and other pollution are serious, and the production cost is high, and the sound-absorbing panels generally have multiple sound-absorbing holes, the area that can be glued is small, and the structural stability is poor. In addition, when the wooden board on the surface of the wooden door is damaged and needs to be maintained, the entire wooden door can only be replaced, and the maintenance cost is relatively high. Therefore, the existing soundproof wooden doors have the problems of serious pollution, high pr...
