Description

Inner open type horizontal open window false middle stile section bar

Technical Field

The utility model relates to a building door and window technical field, in particular to interior open flat-open window false mullion section bar.

Background

The window body is an important component of an outer building envelope and has the important functions of water tightness, air tightness, wind pressure resistance, heat insulation, sound insulation, burglary prevention, lighting, ventilation and the like. The window body is made of various materials, wherein the sectional material window body is widely applied due to the characteristics of low cost, rich shape, durability and the like. The section bar is a solid straight bar which is formed by plastic processing and has a certain section shape and size. The section window body has a plurality of opening and closing modes, while an inward opening type flat-open section window is one of the most common window body opening modes in modern buildings, and the inward opening type flat-open section window is a window body mechanism which is hinged to the side surface of a window sash and is opened inwards.
