Abstract

The heat insulation flat open window sash frame section bar of the utility model mainly solves the technical problem of improving the complete structure of the section bar, etc. The technical proposal is that: the lower side edge of the inner body extends inward an incurved edge fold and forms a containing cavity with the inner side edge; the flank of the lower side edge is a plane; the outer side edge and the upper side edge are connected with each other in a right-angle; the inner and outer side edges, the top and bottom side edges, the incurved edge fold and the excurved edge fold form a containing cavity which can contain combined type angle joint components. The utility model is suitable for various heat insulation flat open window sash frames.

Description

Heat insulated side hang sash frame section

Technical field:

The utility model relates to the section bar of a kind of metal frame, particularly a kind of special cross section.

Background technology:

Window sash frame is all kinds of buildings members commonly used, mostly be wood in early days, steel work, modern building opposite house fan frame structure has proposed requirements at the higher level, diversified window sash frame section bar has appearred on the market, the section configuration of these section bars, can not only make structural rigidity good and slim and graceful, handsome in appearance, and be convenient to the installation of corresponding accessory, and the size of these corner connectors is all bigger, increase window sash frame weight and manufacturing cost, simultaneously, in existing aluminum alloy door and window frame, because its thermal conductivity height, unfavorable energy-conservation, the applicant once proposed a kind of improvement project, and its China Patent No. is 01253698.9, the proprietary design of this structure endosome containing cavity and the application of heat insulating strip, overcome the defective of above-mentioned traditional structure, but, in the ccontaining design of the endosome of this structure, in order to adapt to the installation of existing whole corner connector, outer side edges with curved medial surface, structures such as last chimb and side chimb, make profile structure complicated, manufacturability is poor, and the corner connector size is also big, and versatility is poor, the section bar overall dimension was strengthened, weight increases, and cost is improved.

The utility model content:

Technical problem to be solved in the utility model is, a kind of improved heat insulated side hang sash frame section is provided, and it can the good combined type corner connector of ccontaining door and window universal architecture, and the overall dimensions of section bar is dwindled, and improves manufacturability, reduces cost.

The technical scheme in the invention for solving the above technical problem is: the lower side of section bar endosome has inwardly extended the inner bending limit, inner bending limit and inner side edge constitution content are put the chamber, the side of lower side subtend containing cavity is a plane, outer side edges at right angles is connected with upper side edge, inside and outside side, upper and lower side, inner bending limit and outer bending edge constitute one can ccontaining combined type corner connector containing cavity.

The utility model is with distinctive corner connector containing cavity structure, make heat insulated side hang sash frame material can adopt the littler combined type corner connector of highly versatile physical dimension, not only can dwindle the overall dimensions of section bar, and, reduce the goods cost because designs simplification can improve manufacturability.

Description of drawings:

Fig. 1 is the utility model heat insulated side hang sash frame section section configuration schematic diagram.

The specific embodiment:

With reference to Fig. 1, heat insulated side hang sash frame section includes ectosome 1, heat insulating strip 2 and endosome 3, and heat insulating strip 2 longitudinally connects ectosome 1 respectively and endosome 3 is one.。

Ectosome 1 is the aluminium alloy element that window sash frame is faced an outdoor side, and its outer structure frame can improve the rigidity of ectosome, and outer structure frame has extended overhanging upholstery border, and upholstery border is provided with seal groove.

Heat insulating strip 2 is, adds 25% glass fiber by nylon and makes, and its dual side-edge is provided with fillet, and the section configuration of fillet is identical with the link slot section configuration of inside and

outside body

3,1.

Endosome 3 is that window sash frame is faced the aluminium alloy element that stops up an interior side, and endosome 3 constitutes a containing cavity 34 by inner side edge 30, outer side edges 31, upper side edge 32 and lower side 33;

The side of the lower side 33 subtend containing cavities 34 of endosome 3 is curved comparison of a plane and existing structure, its designs simplification, and favourable section bar is made; Lower side 33 has inwardly extended inner bending limit 331, and inner bending limit 331 is connected with inner side edge 30 again, inner bending limit 331 and the interior containing cavity 35 that inner side edge 30 constitutes and containing cavity 34 is communicated with; Lower side 33 has outwards extended outer bending edge 332, the outer containing cavity 36 that outer bending edge 332 and outer side edges 31 formations one and containing cavity 34 are communicated with;

Outer side edges 31 at right angles is connected with upper side edge 32, and has last chimb and is connected existing structure relatively, designs simplification; The side of outer side edges 31 subtend containing cavities 34 is a plane, but equally also reduced form equipment structure;

The inner side edge 30 of endosome 3, outer side edges 31, upper side edge 32, lower side 33, inner bending limit 331 and outer bending edge 332 constitute one can ccontaining combined type corner

connector containing cavity

34,35,36.Because above-mentioned peculiar structure design, make heat insulated side hang sash frame section configurable general strong (door and window is all suitable), the combined type corner connector that but automation is produced in a large number, size is little, thus make structure of the present utility model be improved significantly, good manufacturability, dimensional weight reduce, the goods cost reduces.

Claims

1, a kind of heat insulated side hang sash frame section, section bar is made up of ectosome, heat insulating strip and endosome, and heat insulating strip connects inside and outside body respectively and is one, and the inside and outside side and the upper and lower side of endosome constitute a containing cavity, lower side extends outer bending edge and constitutes outer containing cavity, it is characterized in that:

The lower side (33) of a endosome (3) has inwardly extended inner bending limit (331), and inner bending limit (331) and inner side edge (30) constitution content are put chamber (35);

B. the side of lower side (33) subtend containing cavity (34) is a plane;

C. outer side edges (31) at right angles is connected with upper side edge (32);
