Abstract
The utility model provides a single-wedge aluminum-plastic composite heat-insulation profile, and belongs to the field of building materials. A dovetail groove formed by wedge-shaped bosses on two sides is formed at the connecting part of an aluminum alloy profile; the outer sides of the wedge-shaped bosses on the two sides warp upwards, and the inner sides are barb-shaped; a dovetail boss is arranged at the connecting part of a plastic steel profile; a cavity is formed in the boss; the edge of the boss is conformal with the aluminum alloy dovetail groove; and the dovetail boss of the plastic steel profile is embedded in the corresponding adaptive dovetail groove, thereby forming the single-wedge aluminum-plastic composite heat-insulation profile. The single-wedge aluminum-plastic composite heat-insulation profile has the advantages of simple and direct structure, high bonding strength and high stability; the structure of the plastic steel profile has a good heat-insulation function, thereby cutting off heat conduction of the aluminum alloy; and furthermore, as the cavity is formed in the dovetail boss, the energy-saving effect of the single-wedge aluminum-plastic composite heat-insulation profile is improved.
Description
Technical field
The plastic-aluminum combined heat insulation section of a kind of single wedge type of the utility model belongs to building material field, is specifically related to composite material section bar.
Background technology
The door and window that uses in the construction work at present, people more and more pay attention to the energy-saving and cost-reducing of door and window.The appearance of plastic-aluminum combined energy-conservation section bar, it is big to have solved the common door and window thermal transmittance of aluminium alloys, the shortcoming of heat preservation energy-saving difference.
But, the present plastic-aluminum combined energy saving door and window on the domestic market, aluminium-plastic composite section plastic-steel part and aluminium alloys part all adopt double-wedge type to be connected, cavity is less, the section bar thermal insulation of breaking is not thorough, cause door and window to reach heat-proof quality still not ideal enough.In addition, the Hardware fitting notch is lack of standardization, has reduced its versatility.
The utility model content
The utility model purpose provides the plastic-aluminum combined heat insulation section of a kind of single wedge type, to give more stable syndeton of aluminium-plastic composite section and better heat preservation and insulation.
The utility model purpose is achieved by the following technical solution:
The plastic-aluminum combined heat insulation section of a kind of single wedge type of the utility model, form by aluminium alloy extrusions, plastic-steel section bar and steel lining, characteristics are dovetail grooves that the connecting portion at aluminium alloy extrusions has the wedge shape boss by both sides to constitute, and the outside of both sides wedge shape boss upwarps, and the inboard is barb; The connecting portion of plastic-steel section bar is a dovetail type boss, and the boss indoor design has a cavity, and the flange of boss and aluminium alloys dovetail groove are fitted shape, in the adaptive dovetail groove that the dovetail type boss embedding of plastic-steel section bar is corresponding, forms the plastic-aluminum combined heat insulation section of single wedge type.
The design embeds in the adaptive dovetail groove of aluminium alloy extrusions correspondence by the dovetail type boss with plastic-steel section bar, form the plastic-aluminum combined heat insulation section of single wedge type, the design's structure is simple and direct, bond strength and stability are high, and not only the structure of plastic-steel section bar has good heat-blocking action, has cut off the conduction of heat of aluminium alloy extrusions, and because the indoor design of dovetail type boss has a cavity, more improved the design's energy-saving effect,, promoted the versatility of product in addition with the standardization of Hardware fitting notch.

The specific embodiment
How now further specify the utility model in conjunction with the accompanying drawings implements:
A kind of single wedge type aluminium-plastic composite section of the utility model, by the aluminium alloy extrusions 1 that single cavity configuration I is arranged, the three-cavity structure of forming by the plastic-steel section bar 2 and the steel lining 3 of two cavity configuration II III, the dovetail groove 1-1 that has the wedge shape boss 1-2 by both sides to constitute at the connecting portion of aluminium alloy extrusions 1, the outside of both sides wedge shape boss 1-2 upwarps, the inboard is barb 1-3, the connecting portion of plastic-steel section bar 2 is dovetail type boss 2-1, boss 2-1 indoor design has a cavity II, the flange 2-2 of boss 2-1 and aluminium alloys dovetail groove 1-1 fit shape, plastic-steel section bar 2 dovetail type boss 2-1 are embedded among the corresponding adaptive dovetail groove 1-1, then with roller along aluminium alloy extrusions 1 connecting portion both sides wedge shape boss 1-2 upwarp the outside roll extrusion, inboard barb 1-3 pressurized then hooks plastic-steel section bar 2, forms the plastic-aluminum combined heat insulation section of single wedge type.
Be connected with steel lining 3 by screw in the I chamber of plastic-steel section bar 2, simultaneously, design has and is convenient to the screw hole 2-3 that is connected with other section bar on the plastic-steel section bar 2.
Claims (1)
1. plastic-aluminum combined heat insulation section of single wedge type, form by aluminium alloy extrusions, plastic-steel section bar and steel lining, it is characterized in that the dovetail groove that connecting portion at aluminium alloy extrusions has the wedge shape boss by both sides to constitute, the outside of both sides wedge shape boss upwarps, and the inboard is barb; The connecting portion of plastic-steel section bar is a dovetail type boss, and the flange of boss and aluminium alloys dovetail groove are fitted shape, in the adaptive dovetail groove that the dovetail type boss embedding of plastic-steel section bar is corresponding, forms the plastic-aluminum combined heat insulation section of single wedge type.
