[0032] Example one:

[0033] Please see Figure 1 , Figure 2 and Figure 3 The profile installation structure shown in a preferred embodiment of the application includes edge beam 1, first angle code 2, main beam 3, second angle code 4 and auxiliary beam 5. Multiple edge beams 1 enclose the outer frame 21 of the frame structure, and multiple parallel main beams 3 are connected between the two oppositely arranged edge beams 1 at both ends through first angle codes 2, and multiple auxiliary beams 5 are connected between the adjacent two main beams 3 at both ends through second angle codes 4, forming a complete frame structure. The frame structure in this embodiment is applied to the construction of an aluminum alloy sunlight room.

[0034] Please seeFigure 1 The side beam 1 is surrounded by the first side 11, the second side 12, the third side 13 and the fourth side 14, and has a rectangular frame shape. During installation, the first side 11 and the third side 13 are both horizontally arranged, and the first side 11 is above the third side 13. The second side 12 is connected between the first side 11 and the third side 13, and the middle part thereof is recessed inward to form a rectangular installation slot 15. The installation slot 15 has a transverse surface 151 parallel to the first side 11, and a longitudinal surface 152 connected between two transverse surfaces 151. The two transverse surfaces 151 are respectively protruded toward the other transverse surface 151 to form two long and opposite slot buckles 153. A slot cover (not shown in the figure) matched with the installation slot 15 can be detachably connected to the slot buckles 153, preventing dust accumulation in the installation slot 15, and helping to improve the appearance.

[0035] The side beam 1 also includes a light strip rack 16. The light strip rack 16 is connected to the second side 12 and is below the installation slot 15. The light strip rack 16 includes a long and strip-shaped rack body 161, a reinforcing plate 162 and a sliding groove 163. The rack body 161 and the outer wall of the second side 12 jointly form a rectangular frame structure with an open bottom. The reinforcing plate 162 is parallel to the third side 13 and is directly connected between the rack body 161 and the second side 12, for connecting and carrying the light strip. The opening of the rack body 161 and the position opposite thereto on the second side 12 respectively form long and strip-shaped sliding grooves 163, which are configured as hook-shaped structures bent upward inside the rack body 161, for detachably connecting a light strip cover (not shown in the figure).

[0036] The side beam 1 also includes two groups of partition pieces 17. The partition pieces 17 are long and strip-shaped protrusions. Each group of partition pieces 17 includes one partition piece 17 protruding from the second side 12 and one partition piece 17 protruding from the fourth side 14, and the two partition pieces 17 in the same group are oppositely arranged and separated from each other. The two groups of partition pieces 17 are respectively arranged adjacent to the first side 11 and the third side 13, and the partition pieces 17 and the first side 11 and the third side 13 respectively form a long and strip-shaped connecting slot 171. When a T-shaped butt joint slot is inserted into the connecting slot 171, the linear splicing of two side beams 1 can be achieved; when a constraint corner slot is inserted into the connecting slot 171, the connection of two side beams 1 with the end cut into an inclined surface can be achieved.

[0037] The first corner code 2 comprises an outer frame 21, a reinforcing beam 22 and mounting columns 23. The outer frame 21 is configured as a rectangular frame fitting into the mounting groove 15, and its thickness is greater than the depth of the mounting groove 15. The outer frame 21 comprises two opposite abutting surfaces 211 and two opposite structural surfaces 212. The reinforcing beam 22 is directly connected to the middle part of the inner wall of the two abutting surfaces 211, used to strengthen the structure of the first corner code 2, and the two ends of the reinforcing beam 22 are flush with the outer frame 21. Four mounting columns 23 parallel to the outer frame 21 and flush with the outer frame 21 at both ends are respectively connected to the four corners inside the outer frame 21. The mounting column 23 is configured as a cylindrical shape, and its side facing the inside of the outer frame 21 is open, which is convenient for the configuration of the shape. The inner wall of the mounting column 23 is a smooth arc surface.

[0038] When the first corner code 2 is mounted on the edge beam 1, one end of the first corner code 2 is tightly abutted to the longitudinal surface 152 of the mounting groove 15, and the outer walls of the two abutting surfaces 211 are abutted to the groove buckle 153, at this time the first corner code 2 is perpendicular to the edge beam 1. After positioning the first corner code 2 to the preset position, the first screw 201 is rotated and inserted into the mounting column 23. Since the diameter of the first screw 201 fits into the mounting column 23, the inner wall of the mounting column 23 is threaded, forming a threaded structure fitting the first screw 201. After the first screw 201 penetrates the mounting column 23, it is embedded in the longitudinal surface 152 of the mounting groove 15, realizing the tight connection of the first corner code 2 and the edge beam 1.

[0039] Please refer to Figure 2 and Figure 3 The main beam 3 comprises a bearing surface 31, a support surface 32 and a closing surface 33.

The bottoms of the two support surfaces 32 are connected to each other through the closing surface 33, forming a frame-shaped strip structure fitting the first corner code 2. The top of the support surface 32 is its hanging end 321. The hanging end 321 has an inclined surface facing the inside, which is used to hang the second corner code 4.

[0040] The inner wall of the support surface 32 is connected with a vertical cover surface 34 near the hanging end 321, and the two cover surfaces 34 are located on the inner side of the support surface 32. The end of the cover surface 34 away from the support surface 32 is bent and partially compressed towards the inside, forming a set of opposite stepped cover buckles 341, which are used to detachably connect the matched main beam cover plate 35, inhibit dust accumulation and improve the aesthetic appearance.

[0041] Another set of partition pieces 17 is also formed on the inner wall of the support surface 32 below the cover surface 34. The partition piece 17 is formed above the bearing surface 31, and together with the bearing surface 31 forms another connecting groove 171.

[0042] When the main beam 3 is installed on the first corner code 2, one end of the main beam 3 is sleeved outside the first corner code 2, so that the load-bearing surface 31 is supported on the abutting surface 211, and the bottom of the main beam 3 is cut to form a notch matched with the lamp strip frame 16, so that the end of the main beam 3 abuts against the second side surface 12. The connection is achieved by penetrating the load-bearing surface 31 and the abutting surface 211 with the first screw 201, at this time the second screw 202 is almost not stressed, which helps to prolong the service life. After the screw installation is completed, the main beam cover plate 35 is covered.

[0043] Please refer to Figure 3 The second corner code 4 is integrally configured in a strip shape, and has a first side 41 and a second side 42 connected perpendicularly to each other.

The end of the second side 42 away from the first side 41 is formed with a filling portion 421, the thickness of the filling portion 421 is greater than the thickness of the second side 42, and the side of the second side 42 close to the first side 41 is formed with two screw grooves 412 parallel to the second side 42. The screw grooves 412 are used for positioning of the screw, and facilitate constraint of the sharp end of the screw during operation.

[0044] When the second corner code 4 is installed on the main beam 3, the hook 411 is hooked on the hooking end 321 of the supporting surface 32, and the third screw 401 is sequentially penetrated through the screw grooves 412 on the first side 41 and the supporting surface 32, so that the second corner code 4 is tightly connected to the main beam 3.

[0045] The auxiliary beam 5 includes a connecting surface 51, two extension side surfaces 52 and supporting clamping pieces 53. The connecting surface 51 is perpendicularly connected to the middle portions of the two extension side surfaces 52 on both sides, and a set of supporting clamping pieces 53 are respectively protruded on the inner walls of the two extension side surfaces 52 in opposite positions. The supporting clamping pieces 53 are located above the connecting surface 51, and the distance between the supporting clamping pieces 53 and the connecting surface 51 is slightly greater than the thickness of the filling portion 421, facilitating insertion of the second side 42. The top portions of the two extension side surfaces 52 are formed with another set of cover plate buckles 341, for detachably connecting the matched auxiliary beam cover plate 54.

[0046] When the auxiliary beam 5 is installed on the second corner code 4, the second side 42 of the second corner code 4 is inserted between the supporting clamping pieces 53 and the connecting surface 51, and the fourth screw 402 is sequentially penetrated through the screw grooves 412 on the second side 42 and the connecting surface 51, so that the auxiliary beam 5 is supported on the second corner code 4. Since the auxiliary beam 5 is almost not stressed, and itself adopts a lighter aluminum profile, the connection strength is sufficient to support. After the fourth screw 402 is connected, the auxiliary beam cover plate 54 is covered.
