Description

A kind of aluminium alloy extrusions and special-purpose connecting bend thereof

The utility model relates to a kind of aluminium alloy extrusions, particularly relates to a kind of aluminium alloy extrusions of using as housing, also relates to the special-purpose connecting bend that connects this section bar.

At present, the section of the aluminium alloy extrusions of using as housing mostly is the right angle rectangle, is made up of outer wall, inner chamber and section bar deep floor.The version of this section bar is too simple, and lateral rigidity is low, and is stressed unreasonable, behind this section bar composition framework, easily takes place to misplace and rock.And rectangular profile makes rainwater be trapped in the housing inboard that section bar is formed easily, can not in time discharge, and can cause the corrosion of aluminium alloy extrusions.Simultaneously, the pulling rivet drawing is often adopted in the connection of aluminium alloy extrusions, and intensity is lower, and construction also comparatively bothers.

The purpose of this utility model is to provide a kind of aluminium alloy extrusions, change traditional right-angle structure, the intensity of stiffening profile itself, the stability of the housing that improves lateral rigidity and be assembled into, solve the problem that rainwater is detained, the special-purpose connecting bend that connects this aluminium alloy extrusions also is provided simultaneously, the intensity of the corner node of housing is improved, easy for installation.To achieve these goals, the technical solution of the utility model is as follows:

A kind of aluminium alloy extrusions, form by outer wall, cavity and section bar deep floor, it is characterized in that there is a triangle boss inboard on the section material section, this triangle boss protrudes to the section bar outer surface, triangle boss by the inclined-plane, face directly with the boss top and form, the section bar deep floor is separated into triangular cavity and rectangular enclosure near triangle boss one side and with the section bar cavity, and there is a rectangular boss in the outside on the section material section.

The inclined-plane of triangle boss is 45 ° on the described aluminium alloy extrusions.

Two angles in the described aluminium alloy extrusions section outside are fillet.

A kind of special-purpose connecting bend that connects described aluminium alloy extrusions, form by outer wall, inner chamber, it is characterized in that there is triangle boss the elbow bend inboard, triangle boss by face directly, inclined-plane and boss top form, the elbow two ends respectively are provided with a section bar interface, respectively stretch out an insertion end on two section bar interfaces, the drift angle outer surface of special-purpose connecting bend is a rounded shapes.

The inclined-plane of the triangle boss on the special-purpose connecting bend of described aluminium alloy extrusions is 45 °.

Insertion end outer surface on the special-purpose connecting bend of described aluminium alloy extrusions is circular-arc, and the triangle boss inboard is provided with the elbow ribs, and the elbow ribs is separated into triangle inner chamber and rectangular inner cavity to the elbow inner chamber.

Have the section bar floor on the insertion end on the special-purpose connecting bend of described aluminium alloy extrusions and insert mouth.

Building block principle is as follows: just can form a Pin outside framework by the mode of plug-in mounting with four special-purpose connecting bends and four aluminium alloy extrusions.During assembling, as long as two insertion ends of special-purpose connecting bend are inserted respectively in the cavity at aluminium alloy extrusions two ends, the deep floor of section bar inserts the section bar floor of offering on the elbow bend insertion end and inserts mouth.The section bar end face aligns identical with the interface of elbow, the triangle boss of section bar also aligns with the triangle boss of elbow and coincide.

The advantage of this aluminium alloy extrusions is:

Owing to adopted leg-of-mutton inclined-plane boss, the lateral rigidity of section bar improved.After being assembled into framework, good stability, rainwater are convenient to drain smoothly.It is more closely knit reliable that the triangular ramp boss makes peripheral frame combine with its fixing material object.Deep floor has been guaranteed the intensity of triangle boss near triangle boss one side.

The advantage of special-purpose connecting bend that connects this aluminium alloy extrusions is as follows:

Insertion end is arranged on the connecting bend, can directly insert in the cavity at section bar two ends, assemble convenient.The deep floor of aluminium alloy extrusions inserts the section bar of offering on the connecting bend insertion end and inserts mouth, and the intensity of node is improved.Be provided with deep floor near the triangle boss on the special-purpose connecting bend, the elbow outer wall thickness is greater than the thickness of section bar outer wall, thereby guaranteed the intensity of frame corners node.The outer corner of special-purpose connecting bend adopts fillet structure, and is stressed more even, reduced the stress mutation and the stress at drift angle place and concentrated.

The aluminium alloy extrusions that provides with the utility model is connected elbow bend with special-purpose, makes the assembling of outside framework simpler, can increase work efficiency.

Below in conjunction with accompanying drawing embodiment of the present utility model is done more detailed description:

Fig. 1 is the sectional drawing of aluminium alloy extrusions;

Fig. 2 is the front view that connects the special-purpose right angle connecting bend of aluminium alloy extrusions;

Fig. 3 is the vertical view that connects the special-purpose right angle connecting bend of aluminium alloy extrusions;

Fig. 4 is the structural representation of a corner node of the outside framework that is assembled into of aluminium alloy extrusions and special-purpose right angle connecting bend.

As shown in Figure 1, aluminium alloy extrusions is made up of outer wall, cavity and section bar deep floor 2, the outer wall section has increased a triangular ramp boss, and the inclined-plane is at 45, triangle boss by inclined-plane 1, face directly 4 and boss top 5, deep floor 2 cavity is separated into cavity 10 and cavity 18 two parts.Two lateral angles of section material section become circular-arc, on the end lateral angle place outer wall rectangular boss 3 are arranged, and have strengthened intensity.

As Fig. 2, the special-purpose right angle of aluminium alloy extrusions shown in Figure 3 connecting bend.Be made up of outer wall, inner chamber, there is triangle boss the elbow bend inboard, triangle boss by face 13 directly, inclined-plane 15 and boss top 14 form, the inclined-plane 15 of triangle boss is 45 °.The elbow two ends respectively are provided with on 12, two section bar interfaces 12 of a section bar interface respectively stretches out an insertion end 8, and the drift angle outer surface 9 of elbow is a rounded shapes.Insertion end 8 outer surfaces are circular-arc, and the triangle boss inboard is provided with elbow ribs 6, and the elbow ribs is separated into triangle inner chamber 11 and rectangular inner cavity 17 to the elbow inner chamber.Have the section bar floor on the insertion end and insert mouth 7.Have one to thicken projection 16 with place, the catercorner angle of triangle boss outer wall on the special-purpose connecting bend.

As shown in Figure 4, just can form a Pin outside framework with four special-purpose right angle connecting bends 19 and four aluminium alloy extrusions 20 by the mode of plug-in mounting.During assembling, as long as two insertion ends 8 of special-purpose right angle connecting bend 19 are inserted respectively in the cavity at aluminium alloy extrusions 20 two ends, the deep floor 2 of section bar inserts the section bar floor of offering on the right angle connecting bend insertion end and inserts mouth 7.The section bar end face aligns identical with the interface 12 of elbow, the triangle boss end face of section bar also aligns with the triangle boss end face of elbow and coincide.
