The utility model adopts the technical scheme as follows:
a two-piece type micro-expansion cast aluminum corner brace comprises a left piece and a right piece which are buckled, wherein the left piece and the right piece are in the same right-angle shape, and buckling seams of the two right-angle sides are respectively and vertically provided with a pin hole with internal threads inwards; two sides of the aluminum corner connector are provided with glue guide grooves, and the glue guide grooves are communicated with the pin holes through glue guide holes; the pin hole is internally screwed with a pin, the pin is internally provided with a glue injection hole, and the pin is externally provided with a thread.
Lead gluey groove and be 45 skewed slots and two right angle bending groove intercommunications and constitute, lead gluey groove and be equipped with the inside gluey hole of leading of intercommunication of aluminium angle sign indicating number, lead gluey hole and pinhole intercommunication.
The left valve and the right valve are respectively provided with a half pin hole by taking the buckling seam as a symmetrical axis.
Compared with the prior art, the utility model discloses following beneficial technological effect has:
the utility model discloses a clearance between aluminium angle sign indicating number and the section bar cavity is eliminated in the micro-expansion of angle sign indicating number, effectively eliminates the jump between the adjacent frame behind the group angle, guarantees the pleasing to the eye of outward appearance. Frame and aluminium angle sign indicating number installation back through to inside inject into two ingredient group angle glue and improve joint strength, can prevent effectively that frame bight from connecting not hard up, compromise inside and outside, increased the firm degree of installation in the very big degree.

Detailed Description
The present invention will be further described with reference to the accompanying fig. 1-6, but the scope of the present invention is not limited by the accompanying drawings.
Example 1
A two-piece type micro-expansion cast aluminum angle bracket is used for connecting two frames 7 with 45-degree end sections, and comprises a left piece 1 and a right piece 2 which are buckled with each other, wherein the left piece 1 and the right piece 2 are in the same right-angle shape, and buckling seams of the two right-angle sides are respectively vertically provided with a pin hole 3 with internal threads inwards; two sides of the aluminum corner connector are provided with glue guide grooves 4, and the glue guide grooves 4 are communicated with the pin holes 3 through glue guide holes 11; the pin hole 3 is internally screwed with a pin 5, the pin 5 is internally provided with a glue injection hole 6, and the pin 5 is externally provided with a thread.
Lead gluey groove 4 and be 45 skewed slots and two right angle bending groove intercommunications and constitute, lead gluey groove 4 and be equipped with the inside gluey hole 11 that leads of aluminium angle sign indicating number, lead gluey hole 11 and pinhole 3 intercommunication.
The left valve 1 and the right valve 2 are respectively provided with a half pin hole 3 by taking the buckling seam as a symmetrical axis.
The left valve and the right valve are cast by aluminum alloy.
The pin 5 is made of stainless steel.
The glue injection hole 6 is in the shape of an inner hexagon bolt.
The external diameter of the thread of the pin 5 is larger than the internal diameter of the pin hole 3.
Example 2
When in use, the left flap 1 and the right flap 2 are firstly buckled together and inserted into the section bar cavity 9 of the end face of 45 degrees of the frame 7. Mounting holes 8 need to be prefabricated on the frame 7 profile, and the positions of the mounting holes correspond to the pin holes 3 of the aluminum corner connectors, as shown in fig. 4.
Then, the pin 5 is screwed into the mounting hole 8 and the pin hole 3 by using an inner hexagonal wrench, and the adjacent frames 7 can be connected through aluminum corner connectors. Because the external diameter of the screw thread of the pin 5 is slightly larger than the internal diameter of the pin hole 3, under the extrusion action of the pin 5, the buckling seam between the left corner brace 1 and the right corner brace 2 is slightly separated, the whole aluminum corner brace is in a micro-expansion state and is filled in the section cavity 9 of the frame 7, the gap between the aluminum corner brace and the section cavity 9 of the frame 7 is eliminated, and the step difference between the adjacent frames after corner combination is eliminated.
And finally, injecting the two-component corner glue through the regular hexagon glue injection hole 6 in the middle of the pin 5 by using the glue nozzle 10. The two-component corner glue enters the glue guide groove 4 through the glue guide hole 11 and is filled in a gap between the aluminum corner connector and the section bar cavity 9. The bonding force generated after the two-component corner glue is cured further improves the corner connection strength between the frames 7.
