Description

Door window mullion section bar

Technical field

The utility model relates to a kind of window mullion section bar.

Background technology

Along with growth in the living standard, the highrise building of some middle and high ends and comfortable house have higher demand with aluminium alloys to the quality on its performance and surface, at present, and popular aluminium door frame and door leaf on the market; Exquisite appearance is difficult for getting rusty, but the cavity of the thermal insulation barriers that adopts is little, the large percentage that causes aluminium in integral material, to account for; Make the price of aluminium increase, increased the cost of material greatly, because aluminium extruded sections has in light weight; Anti-put forth effort strong advantage and be widely used on the building, but not sound insulation of aluminium extruded sections, insulation and defectives such as anti-seismic performance inequality and cost height, and; The existing outward opening window frame section coefficient of expansion is bigger, is prone to the phenomenon of splitting glue after door and window installs, and antiseep property is poor; Decay resistance is bad, and the maintenance expense is high, and insulating properties is bad; Need lightning protection at the highrise building door and window, damping performance is bad, and watertightness is bad.

The utility model content

The utility model provides a kind of and gains in strength, improves the door window mullion section bar of insulation and anti-seismic performance.

The utility model technical solution problem provides following scheme:

A kind of window mullion section bar; Stile and down middle stile in comprising; It is characterized in that: the cross section of stile is inverted T shape in said, and the epipleural right ends of stile is respectively equipped with the draw-in groove that extends to the left and right in said the going up, and is respectively equipped with reinforcing rib on the left and right sides sidewall of stile in said the going up; The adjacent surface of said middle up and down stile is provided with the contiguous block draw-in groove, is fixed together through contiguous block between the said middle up and down stile.

The lower side panel of said down middle stile extends to the left and right, and said left and right sides extension board upper surface has the weather strip draw-in groove.

Stile during the utility model is set to up and down links together through contiguous block between the stile in up and down, and middle up and down stile is split as up-down structure with the structure of former integral body, effectively plays anti seismic efficiency.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Referring to accompanying drawing; A kind of window mullion section bar, stile 1 and down middle stile 2 in comprising, the cross section of said middle stile is inverted T shape; Epipleural 3 right ends of stile 1 are respectively equipped with the draw-in groove 4 that extends to the left and right in said the going up; Be respectively equipped with reinforcing rib 7 on the left and right sides sidewall 5,6 of stile 1 in said go up, said up and down in the adjacent surface of stile 1,2 be provided with contiguous block draw-in groove 8, said up and down in stile 1, be fixed together through contiguous block 9 between 2; The lower side panel 10 of said down middle stile 1,2 extends to the left and right, and said left and right sides extension board upper surface has weather strip draw-in groove 11.

Claims (2)

1. door window mullion section bar; Stile and down middle stile in comprising; It is characterized in that: the cross section of stile is inverted T shape in said, and the epipleural right ends of stile is respectively equipped with the draw-in groove that extends to the left and right in said the going up, and is respectively equipped with reinforcing rib on the left and right sides sidewall of stile in said the going up; The adjacent surface of said middle up and down stile is provided with the contiguous block draw-in groove, is fixed together through contiguous block between the said middle up and down stile.

2. according to said window mullion section bar of claim 1, it is characterized in that: the lower side panel of said down middle stile extends to the left and right, and said left and right sides extension board upper surface has the weather strip draw-in groove.
