Composite profile outer frame end opening framing structure for threshold-free door window

Abstract

The invention relates to a composite profile outer frame end opening framing structure for a threshold-free door window. An outer frame end opening is formed by assembling left and right vertical frames and a lower door frame; the lower door frame adopts a threshold-free door frame; the lower ends of the left and the right vertical frames are placed at the upper parts of the two ends of the threshold-free door frame, and the lower end sides of the vertical frames are connected together with the upper edge of the end part of the threshold-free door frame through threshold-free door cushion blocks; the vertical frames are aluminum wood composite frames comprising outer aluminium alloy profiles and inner wooden battens, and the threshold-free door frame adopts an aluminium alloy frame; vertical cushion blocks are positioned and fastened inside an aluminium alloy profile lower end cavities of the vertical frames through tightening screw; the upper sides of the two ends of the threshold-free door frame are fixedly connected together with the lower end edges of the left and the right vertical frames through the threshold-free door cushion blocks, the vertical cushion blocks and the inner wooden battens; according to the composite profile outer frame end opening framing structure provided by the invention, the framing form between the vertical frames and the threshold-free door frame is simplified and the manufacture process requirements are simplified through a way of mounting the cushion blocks between the vertical frames and the threshold-free door frame; moreover, through the effects of the cushion blocks, the vertical frames are prevented from being in direct contact with the threshold-free door frame, and the wood of the end openings of the vertical frames is protected from being attacked and corroded by water.

Description

Technical field [0001] The invention relates to a composite profile outer frame lower port frame structure for doors and windows without thresholds, belonging to the technical field of building door and window structures. Background technique [0002] In the prior art, doors and windows designed with no sill door structure have different bottom door sills and other frame material designs, so the frame structure of the lower mouth is different from the frame structure of the upper mouth; generally, the mullion is different from the lower mouth of the sill-free door. The door sills are connected after milling, which is complicated in process requirements and difficult to make; and when there are wooden materials on the frame profile, the end surface of the wooden profile at the lower mouth of the mullion is easy to absorb moisture, Moisture will cause wood corrosion and other problems. Summary of the invention [0003] The purpose of the present invention is to overcome the shortco...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, for doors and windows with sillless door structure design, because the bottom sill is different from other frame materials, the frame structure of the lower opening is different from that of the upper opening; The sills are connected by reverse milling, which requires complex process and difficult production; and when there are wooden materials on the frame profiles, the end face of the wooden profiles at the lower opening of the mullion, where it directly contacts the sill, is easy to absorb water, Moisture, which in turn causes problems such as wood corrosion
