Outer frame end opening framing structure for threshold-free door window

Abstract

The invention relates to an 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 two ends of the threshold-free door frame are respectively in direct or indirect connection with the lower end parts of the left and the right vertical frames fixedly; 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 frames are connected together with the upper side of the end part of the threshold-free door frame through threshold-free door cushion blocks; the left and the right vertical frames and the threshold-free door frame are all aluminium alloy frames, vertical cushion blocks are positioned and fastened inside the lower end cavities of the vertical frames through fastening bolts, and upper sides of the two end parts of the threshold-free door frame are fixedly connected together with the lower end sides of the left and the right vertical frames through the threshold-free door frame cushion blocks and the vertical cushion blocks; the outer frame end opening framing structure provided by the invention mainly adopts a way of mounting cushion blocks between the vertical frames and the threshold-free door frame, so that the framing form between the vertical frames and the threshold-free door frame is simplified, and the manufacture process requirements are simplified. Moreover, the entire air tightness of the corners of a threshold-free door is ensured.

Description

technical field [0001] The invention relates to a lower opening frame structure of an outer frame of a sillless door and window, and belongs to the technical field of building door and window structures. Background technique [0002] In the prior art, for doors and windows with sillless door structure design, because the design of 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 milling and reverse type, the process requirements are complicated, the production is difficult and the processors have high technical requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a lower opening group frame structure of the outer frame of doors and windows without sills, which is reasonable in structure and convenient in use and installation. [0004] The object of the present...
