Composite sectional-bar outer frame framing structure of threshold-free door-window

Abstract

The invention relates to a composite sectional-bar outer frame framing structure of a threshold-free door-window. An outer frame is formed by assembling a left vertical frame, a right vertical frame, an upper door frame and a lower door frame, wherein the lower door frame is a threshold-free door frame, the lower end parts of the left vertical frame and the right vertical frame are arranged on the upper parts of the two ends of the threshold-free door frame, and the lower end of each vertical frame is connected with the upper edge of the end part of threshold-free door frame through at least one threshold-free cushion block; two ends of the upper door frame are respectively connected with the upper end parts of the left vertical frame and the right vertical frame by adopting a 45-DEG angular connection way or a 90-DEG angular connection way. By adopting the composite sectional-bar outer-frame framing structure of the threshold-free door-window, the framing form can be simplified, the production technological requirement can be simplified, the direct contact between the vertical frames and the threshold-free door frame can be avoided in the existence of the cushion block, and lumber of a lower opening of the vertical frame is prevented from being corroded by the invasion of the moisture.

Description

technical field [0001] The invention relates to a composite profile outer frame group structure for doors and windows without sills, 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, which requires complex process and difficult production; and when there is wooden material on the frame profile, the end face of the wooden profile 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. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a non...
