The the 2nd: because of there not being the location and tight mutually that is installed by pasting, so its sealing effectiveness is poor along thickness direction.

The 3rd: therefore also unstable when mounted because glass reaches no any location and installed body between middle spacer bar 3 and the section bar 2, also inconvenient installation.

The 4th: the lateral surface of section bar is the plane of veneer, and it is not attractive in appearance that the door and window body after the installation does not have stereovision, profile, and intensity, the non-deformability in simple degree of lip-rounding cross section are all relatively poor.

The the 4th: because its width is narrow.Thereby the space is thinner between the layer glass, is unfavorable for insulation and sound insulation.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of prior art, and provide a kind of a plurality of stepped location divisions of having, spacer bar carries out mutual plug-in card location in reaching with the double-layer glass of installing, both can guarantee the fastness of installing, the stability that has antitypy and external force resistance again also has good looking appearance and can increase the empty stomach flat opening heat-preservation door and window section bar of intermediate space.

The purpose of this utility model is to realize by following technical scheme:

It by a sheet metal through the clod wash seaming enclose constitute outside rib in the having an of hollow and in interleave the two-way ladder section bar of embedding groove, in its rib inboard, outside be one with glass outer mutually by posting the stage portion of putting, by the outside recess of stage portion begin between its inner retaining side medial surface be one with the middle spacer bar slotting embedding groove that closes of insertable card mutually, half stairstepping frame wall in inside and outside rib stage portion and groove have even constituted, and inside and outside rib and lower frame wall have even constituted outer ladder frame wall.

Therefore: remarkable result of the present utility model is:

The 1st: because stairstepping frame wall can form and the firm plug-in card of adjacent each parts location in it, or pressured stage portion and concave part, therefore, can guarantee glass, in circumferential spacing in edge between spacer bar and the plug-in card element, the mutual extrusion location along thickness direction has the stable characteristics of installing.

The 2nd: phase plug-in mounting integrated positioning hierarchic structure has not only solved when double-layer glass is installed and the firm and integrity problem after installing, and, also make the construction assembling more simple and easy, can improve efficiency of construction.

The 3rd: stair-stepping odd-shaped cross section has better intensity and non-deformability than the square-section.

The 4th: lines are obvious, good looking appearance.

The the 5th: have bigger thickness, can make the incubation cavity thickening between the double-layer glass after the assembling, and be more conducive to improve sound insulation and heat insulation effect.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing:
