A kind of door and window corner connecting plastic steel profile

Abstract

The invention relates to a polyvinyl chloride section for corner connection of doors and windows. The end portion of the polyvinyl chloride section for corner connection of the doors and the windows comprises a first blanking slope, wherein a second milling groove is formed in the indoor side of the first blanking slope, a milling opening of the second milling groove is formed in the position, deviating for 2-3mm in a parallel mode from the first blanking slope, of the first blanking slope, and grooving needs to be carried out in the mode that the milling opening is facing the outer side of the polyvinyl chloride section, the width of a groove opening is controlled to be within 6mm, a chip guiding groove is formed in the position, facing the outdoor side, of the second milling groove, a milling opening of the chip guiding groove is formed in the position, inwards deviating for 4-6mm in a parallel mode, of the first blanking slope, an opening of the chip guiding groove needs to face the outer side of the polyvinyl chloride section, and the width of the opening of the chip guiding groove is controlled to range from 3mm to 7mm. According to the polyvinyl chloride section for corner connection of the doors and the windows, the welding strength and leakproofness of the whole polyvinyl chloride section are effectively ensured, the corner assembly mode of the whole corner can be compact in structure and attractive and simple in appearance, and strength is ensured.

Description

technical field [0001] The invention relates to a plastic-steel door and window, in particular to a plastic-steel profile connected at the corner of the door and window. Background technique [0002] Nowadays, the proportion of PVC plastic doors and windows on the market is increasing day by day, and there are many ways and types of corner processing. There are roughly two ways to set the corners of PVC plastic doors and windows on the market. The first one is 45°. That is to say, the frame fan profile is cut at 45°, and then the corners are assembled by corner coding or welding. The second is the 90° group angle, which is to cut the door and window frame leaf horizontally or vertically at 90°, and then use the reverse connection group angle or welded group angle on the corresponding matching section. These two methods have their own advantages and disadvantages, but the use of thin wood PVC plastic windows, PVC plastic windows covered with PVC film and colored PVC plastic...
