Abstract
The utility model belongs to a component in the technical field of building doors and windows, and relates to an aluminium alloy corner profile. The aluminium alloy corner profile comprises a right-angled corner body, six to ten triangular cavities are formed inside the corner body, fixing grooves are formed in the outer side of the corner body, and the bottom of each fixing groove is provided with a flange. The aluminium alloy corner profile is used for connection between door-window frame and sash profiles.
Description
Technical field
The utility model relates to a kind of accessory of alumium alloy door and window, particularly a kind of aluminium alloys corner brace section bar.
Background technology
In the prior art, while making door and window with aluminium alloy extrusions, must in advance section bar be cut according to ORIENTED DOOR AND WINDOW DESIGN size.Then 45° angles are cut in two door-window section bar angle of cut places, then two section bars are firmly connected.Corner brace is exactly the connector that two section bars are connected, and corner brace and door-window section bar are connected firmly and are related to the stability of finished door window shape.When use, door-window section bar inner chamber is inserted respectively at corner brace main body two ends.Use corner combining machine that aluminium alloy extrusions part outer wall is clamp-oned to corner brace holddown groove, and rely on the frictional force between corner brace external surface and profile cavity inner surface that the two is fixed.In order to make this firm and reliable connection, require corner brace intensity high, not yielding.
The corner brace section bar of prior art, as shown in Fig. 2, has right angle type corner brace main body 1, corner brace main body 1 outside indent has two holddown grooves 3, holddown groove 3 sides are ramped shaped, and there are four cavitys 2 and two atriums 6 in corner brace main body 1 inside, and cavity 2 is shaped as trapezoidal and square shape.The cavity shape of this design more easily deforms under Bonding pressure, and corner brace holddown groove only has horizontal frame for movement to fix.Laterally only fix by corner brace surface and the frictional force of Surface of profile.Existing corner brace is easy to make after profile combined corner, forms lateral displacement, frame fan surface irregularity.For corner brace intensity is enough, increase wall thickness, cause waste of material.
Utility model content
The technological deficiency existing in order to solve prior art, the purpose of this utility model is to provide a kind of aluminium alloys corner brace section bar.Cavity adopts triangular structure, increases reinforcing rib, and holddown groove increases longitudinal mechanical anti-skid structure.
To achieve these goals, the technical solution of the utility model is:
A kind of aluminium alloys corner brace section bar, has right angle type corner brace main body, and corner brace main body outside has holddown groove, and corner brace body interior has cavity.Wherein:
Cavity is triangular shaped;
Holddown groove bottom has flange.
The number of cavities of corner brace body interior is 6-10.
Owing to adopting after such scheme, the utility model in use, has reduced the wall thickness of corner brace, has increased reinforcing rib, makes corner brace section bar totally reduce weight, has saved material.Mechanical anti-skidding flange has been arranged at holddown groove bottom, makes frame, fan be not easy to occur sidesway.Frame, fan surfacing attractive in appearance.
Brief description of the drawings
Fig. 1 is a kind of aluminium alloys corner brace section bar front view.
Fig. 2 is existing corner brace section bar front view.
Attached number in the figure:
1. corner brace main body, 2. cavity, 3. holddown groove, 4. flange, 5. atrium.
Detailed description of the invention
Detailed description of the invention explanation below in conjunction with Figure of description 1 to a kind of aluminium alloys corner brace of the utility model section bar.
A kind of aluminium alloys corner brace, has right angle type corner brace main body 1, cuts use according to concrete door-window section bar cavity size.Two legs of right angle type corner brace main body 1 insert door, the window profile inner chamber of preparing to be connected to become right angle.Use corner combining machine to divide outer wall to clamp-on corner brace holddown groove section bars, and rely on the frictional force between the inside and outside surface of corner brace and profile cavity inner surface that the two is fixed.Corner brace main body 1 outside has holddown groove 3, and holddown groove 3 bottoms have flange 4.While using corner combining machine extruding, flange 4 is out of shape, increases the side-friction force of corner brace main body 1 and door-window section bar, door-window section bar is not breakked away, connecting sewing is tight, more firm.Corner brace main body 1 inside has multiple cavitys 2, can alleviate the weight of corner brace, also saves material.Cavity 2 shapes are designed to triangular shaped, make corner brace main body 1 intensity higher.According to the size of corner brace, cavity 2 quantity of corner brace main body 1 inside are 6-10, make corner brace main body 1 intensity higher.
Claims (2)
