Abstract
The utility model provides a muntin sectional bar which is provided with a muntin outer frame (1) and a muntin inner frame (3), wherein thermal insulation strips (2) are installed between the muntin outer frame (1) and the muntin inner frame (3), each of two partial areas on the two sides of the muntin inner frame (3) protrudes outwards to form a first groove (4), an outer wall (31) of each protruding part is provided with a sunken second groove (5) and extends towards the two ends to form outward protruding ends (6) on the two sides of the second groove (5), and the first grooves (4) in the two sides of the muntin inner frame (3) are arranged symmetrically, and each of the cross sections of the first grooves is a circle with an opening. The sectional bar can be matched with other sectional bars in use to manufacture doors and windows and the like, and compared with an existing muntin sectional bar, the muntin sectional bar provided by the utility model is more attractive and has a better thermal insulation effect.
Description
Technical field
The utility model relates to a kind of aluminium extruded sections, especially the middle stile section bar in the heat-insulating bridge-cut-off.
Background technology
Heat insulation broken bridge aluminum profile is section bar at present commonly used, has the outstanding features such as intensity is high, thermal and insulating performance good, daylighting area is large by the door and window of its making.Wherein 63 series are heat insulation broken bridge aluminum profiles of commonly using, and the utility model on its basis centering stile section bar improves, and not only outward appearance is more attractive in appearance for the middle stile section bar after the improvement, and better heat preservation.
Summary of the invention
The purpose of this utility model provides a kind of improved middle stile section bar, to improve its functional performance.
The technical solution of the utility model is: middle stile section bar has middle stile housing and middle stile inside casing, between middle stile housing and the middle stile inside casing heat insulating strip is installed, each outwards convexes to form the first groove the subregion of the both sides of described middle stile inside casing, the outer wall of bossing has the second groove of a depression, and the outer wall of bossing extends in both sides from the second groove to two ends form outside jag.The first groove of described middle stile inside casing both sides is symmetrical arranged and cross section is the circle that opening is arranged.
Adopt the middle stile section bar of said structure, more attractive in appearance, and rational in infrastructure, cooperate with other section bar to have increased tightness, reached the effect of better heat preservation.
Description of drawings
Fig. 1 is the schematic diagram of stile's transverse section of section material structure in 63 series of the prior art.
Fig. 2 is the schematic diagram of the utility model cross-sectional structure.
The specific embodiment
Further specify concrete structure of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 2, middle stile of the present utility model section bar has middle stile housing 1 and middle stile inside casing 3, between middle stile housing 1 and the middle stile inside casing 3 heat insulating strip 2 is installed; The subregion of middle stile inside casing 3 both sides outwards convexes to form the first groove 4, two the first grooves 4 are symmetrical arranged, its cross section is the circle that opening is arranged, the outer wall 31 of bossing has the second groove 5 of a depression, and the outer wall 31 of bossing extends in both sides from the second groove 5 to two ends form outside jag 6; There is respectively baffle plate 11 and another baffle plate 12 with the wool top mounting groove both sides of middle stile housing 1; The relative position of middle stile housing 1 and middle stile inside casing 3 is respectively equipped with the link slot 13 that adapts with heat insulating strip, is used for connecting heat insulating strip.
The purposes of this middle stile section bar and installation and application are identical with existing middle stile section bar, can jointly use with other section bars, are used for making door and window etc.
