Indoor composite door

Abstract

The invention relates to an indoor composite door, which is composed of a door frame, door bottom plates, door panels, a door jamb, fillings, end caps, door jamb press strips, sealing wool tops and fasten nails. The door is characterized in that two door bottom plates made of plasterboard parallelly clamp the door frame made of light steel frame, fillings are filled therebetween and are made fromrock wool and glass wool material, the end caps made of rubber wrap the peripheral edges of the door bottom plates; the door jamb made of aluminium alloy is fixedly connected with the door frame through the metal fasten nails, and the door bottom plates, the door frame, and the door jamb are fixed into one body; the two door panels are respectively attached to two door base plates which are made of fireproof decorative plate; and the door jamb press strips with the sealing wool tops buckle on the door jamb to combine the indoor composite door. The indoor composite door has excellent fireproofperformance, thermal insulation performance, sound insulation performance, and will not generate warpage because of environmental influence in use.

Description

technical field [0001] The invention relates to an indoor composite door with good performances of fire prevention, heat preservation and heat insulation. Background technique [0002] At present, although the existing interior doors have various styles, they are all made of wooden materials, which have problems such as non-fire prevention, poor thermal insulation and sound insulation performance, and easy warping and deformation after long-term use. With the improvement of people's living standards, the fireproof, thermal insulation and sound insulation performance requirements of interior doors are higher, and the existing wooden interior doors can no longer meet the current requirements. Contents of the invention [0003] The present invention overcomes the defects of the above-mentioned indoor wooden door, and aims to provide an indoor composite door with good fireproof performance, thermal insulation performance and sound insulation performance, and the door body will...
