Aluminium alloy outer frame framing structure for threshold-free door window

Abstract

The invention discloses an aluminium alloy outer frame framing structure for a threshold-free door window. An outer frame is formed by assembling left and right vertical frames, an upper door frame and a lower door frame; the lower door frame is a threshold-free door frame; the lower end parts 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 frame are connected together with the upper side of the end part of the threshold-free door frame at least through one threshold-free door cushion block; the two ends of the upper door frame are respectively connected together with the upper end parts of the left and the right vertical frames at an angle of 45 degrees or 90 degrees; the two vertical frames and the threshold-free door frame are aluminium alloy frames, vertical cushion blocks are positioned and fastened inside the lower end cavities of the vertical frames through fastening bolts, and the upper sides of the two ends of the threshold-free door frame are fixedly connected together with the lower end sides of the left and the right vertical frames through threshold-free door cushion blocks and the vertical cushion blocks. The framing form between the vertical frames and the threshold-free door frame is simplified, the manufacture process requirements are simplified, and moreover the integral air tightness of the threshold-free door corners is ensured.

Description

Technical field [0001] The invention relates to an aluminum alloy outer frame group 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, the door and window outer frame of the sillless door structure design is mainly assembled by the left and right vertical frames, the upper door frame and the lower door frame. Because the bottom door sill is different from other frame materials, the frame structure of the lower mouth is different from that of the upper frame. The frame structure of the mouth is different; generally, at the lower mouth of the door without sills, the mullion and the sill are connected after milling. The process requirements are complicated, and the production difficulty is high and the technical requirements of the processor are high. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of th...
