摘要:
The present invention relates to a method for manufacturing a door frame and a panel, and more particularly, to a method for manufacturing a door frame and a panel, in which door frames and panels of a variety of sizes can be manufactured by a common use facility consisting of a single system including a single synthetic resin panel mold without the need for using a new mold for a changed specification and size of the door frame in manufacturing the door frame. The method for manufacturing a door frame according to the present invention comprises the following steps: molding a synthetic resin panel; cutting the panel to correspond to the size of a frame; treating one side of the panel by wrapping said side with a wrapping sheet; forming a plurality of bending holes to bend the panel; applying an adhesive to the side on which the bending holes are formed; attaching a shape retention member; bending the frame to form a door frame; and forming a synthetic resin layer at the ends of the shape retention member so as to complete the door frame.

본 발명은 문짝 프레임 및 패널 제조방법에 관한 것으로 더 상세하게는 문짝 제작에 쓰이는 프레임을 제작하는데 있어서 문짝을 형성하는 프레임의 규격 및 치수 변경에 대하여 새로운 금형을 사용하지 않고 하나의 합성수지 패널 금형에 의해 단일 시스템으로 이루어진 공용화 설비를 통해 다양한 규격의 프레임과 패널을 제작할 수 있는 문짝 프레임 및 패널 제조방법에 관한 것이다. 본 발명의 문짝 프레임 제조방법은 합성수지 패널 성형 단계, 프레임 규격에 대응되도록 재단하는 단계, 패널의 한쪽 면을 랩핑 시트로 감쌓아 표면을 처리하는 랩핑 단계, 패널을 굽혀서 접을 수 있는 복수의 굽힘 홈을 형성하는 단계, 굽힘 홈이 형성된 면에 접착제를 도포하는 단계, 보형부재 부착 단계, 프레임을 형성하는 굽힘 단계, 보형부재 단부에 합성수지층을 형성하여 문짝 프레임을 형성하는 단계로 이루어지는 것을 특징으로 한다.
摘要:
A door comprising first and second door skins secured to each other to form a cavity therebetween filled with expended foam. Each of the door skins has an opening therethrough for receiving a glass insert and a flange portion. Distal ends of the flange portions of the first and second door skins engage each other in an overlapping relationship by the expansion pressure of the expanded foam. The door further comprises a glazing rim member having a leg portion snap-locked between the flange portions of the first and second door skins. The method for assembling the door comprises the steps of filling the cavity between the door skins with foam material, then inserting the glass insert through the openings in the door skins and mounting the glazing rim member to the first door skin by snap-locking between the flange portions of the first and second door skins.

Composite products comprising or incorporating compression moldings of waste or filler particles (16) encapsulated and bound together by a thermoplastic binder (15) into a compacted mass of a shape selected for its end use, the compression molding being prepared by intensely mixing together particles of thermoplastic and waste or filler material to raise their temperature to bring the thermoplastic particles to a molten state where they coat the waste or filler particles (16), then compression molding the hot coated waste or filler particles.
摘要:
A structural panel includes a shell having spaced first and second exterior panels and frame members adjacent edges of the panels, and at least one polymeric sheet disposed between the exterior panels and bonded to an adjacent exterior panel. The polymeric sheet is made of a thermoplastic material and has a plurality of openings through its thickness spaced apart by flat wall portions of the polymeric sheet. Stiffeners are disposed between the polymeric sheets and are secured by polymeric end caps. The end caps are made of a thermoplastic material and have a plurality of openings through their thickness for receiving the stiffeners. A foam insulation material fills substantially all the space between the polymeric sheets, stiffeners, and frame members in the shell interior. At least one blast- or ballistic- resistant core layer may be disposed adjacent the at least one polymeric sheet.

A new traffic impact door construction is provided together with a method of making same. The door body comprises a frame that is made up of a plurality of peripheral frame members (2A-2D) and a plurality of interior frame members (4A-4D), with the frame members being extruded beam-type parts made of a thermoplastic material, and front and back door face panels (34A, 34B) that are ultrasonically bonded to the frame. At least one of the frame members serves as a door post mount and other frame members serve as a supporting frame for a window pane (64A, 64B). The frame members also are adapted to serve as mounts for flexible and resilient door edge seals (54, 56).
