Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to a door and window and its assembly method. Background Technology

[0002] With the rapid development of urban construction, the design of building facades is receiving increasing attention. More and more buildings are adopting glass curtain walls or large-opening balconies to enhance the aesthetic appeal of their facades. Both glass curtain walls and large-opening balconies require large-sized doors and windows. To further enhance the design, some doors and windows are spliced ​​at an angle, resulting in two or more sides of the building facade being glass. However, large doors and windows present challenges in handling and transportation due to their size or the fact that they are multi-sided doors and windows spliced ​​at an angle. To solve this problem, existing large doors and windows often adopt a modular design, transporting each part of the large door or window separately to the construction site and then assembling the two frame profiles together using connectors. In particular, when the two frame profiles of a door or window need to be spliced ​​at an angle, connectors are typically used to join the two frame profiles together at that angle. However, existing door and window frames spliced ​​at a certain angle have the following defects: due to splicing errors and component processing errors, the joint surfaces of the two splicing frame profiles are prone to misalignment, and existing connectors cannot reduce or eliminate this misalignment, thus affecting the appearance of the doors and windows and their normal closing. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a door and window that can reduce or eliminate the misalignment of the splicing surfaces of the splicing frame profiles when splicing the door and window frames, thereby giving the door and window an aesthetic appearance and ensuring the normal closing function of the door and window.

[0004] To achieve the above objectives, the present invention provides a door and window, comprising a door and window frame composed of multiple frame profiles having hollow cavities. The door and window frame includes a first frame profile and a second frame profile inclined relative to the first frame profile. The ends of the first and second frame profiles are fixedly connected by corner connectors. The corner connectors are disposed in the hollow cavities of the first and second frame profiles and are fixedly connected to the first and second frame profiles by fixing screws. The corner connectors include corner blocks, connecting blocks, and adjusting screws. The corner blocks include two corner arms, which are respectively disposed in the hollow cavities of the first and second frame profiles. Parallel to the first and second frame profiles, the connecting block includes two connecting arms connected at their ends. The two connecting arms are respectively disposed in the hollow cavities of the first and second frame profiles, located outside the two corner arms, and parallel to the first and second frame profiles. A gap is provided between the corner arms and the connecting arms disposed outside the corner arms for the insertion of the adjusting screw. The first and second frame profiles are provided with a first through hole corresponding to the gap. By inserting the adjusting screw into the gap through the first through hole, the corner block is pressed against the inner wall of the hollow cavity of the first and second frame profiles.

[0005] When assembling door and window frames, one corner arm of the corner assembly block and one connecting arm of the connecting block are inserted into the hollow cavity of the first frame profile and fixed to the first frame profile with fixing screws. Then, the other corner arm of the corner assembly block and the other connecting arm of the connecting block are inserted into the hollow cavity of the second frame profile and fixed to the second frame profile with fixing screws. Next, the adjusting screw is inserted through the first through hole on the first and second frame profiles to create a gap. Thus, the ends of the first and second frame profiles are fixedly connected by corner connectors. When the adjusting screw is inserted, it presses against the corner arm and connecting arm, thereby pressing the corner arm against the inner wall of the hollow cavity of the first and second frame profiles. This also pushes the ends of the first and second frame profiles slightly in the joint direction, achieving the purpose of fine adjustment of the joint surface. This reduces or eliminates the splicing misalignment of the door and window frame joint surfaces, giving the doors and windows an aesthetic appearance and ensuring their normal closing function.

[0006] A preferred embodiment of the above technical solution is as follows: the connecting block includes a first connecting arm and a second connecting arm spaced apart from the first connecting arm. The first connecting arm has a threaded hole at one end near the second connecting arm, and the second connecting arm has a second through hole corresponding to the threaded hole. A connecting screw is sequentially inserted into the second through hole and the threaded hole. The first connecting arm and the second connecting arm are fixedly connected to the first frame profile and the second frame profile by the fixing screw. The first frame profile and / or the second frame profile have an opening, and the screw head of the connecting screw protrudes from the opening. The adjusting screw is inserted into the gap between the corner arm and the first connecting arm.

[0007] Before assembling the frame profiles, first assemble the first and second connecting arms together using connecting screws. When assembling the frame profiles, first insert the two corner arms of the corner assembly block and the first and second connecting arms of the connecting block into the hollow cavities of the first and second frame profiles respectively, and secure them with fixing screws. At this point, the fixing screws are not tightened. Then, rotate the screw head exposed from the opening. The connecting screw pushes the second connecting arm towards the first connecting arm, which in turn slightly moves the end of the first frame profile fixed to the first connecting arm in the joining direction, achieving fine-tuning of the joining surface. Then tighten the fixing screws. Next, insert the adjusting screw into the gap between the corner arms and the first connecting arm to further adjust the splicing misalignment of the joining surfaces of the first and second frame profiles. This further reduces or eliminates the splicing misalignment of the door and window frame joining surfaces, giving the doors and windows an aesthetically pleasing appearance and ensuring their normal closing function.

[0008] A preferred embodiment of the above technical solution is as follows: a spring is fitted onto the connecting screw, and the two ends of the spring abut against the first connecting arm and the second connecting arm, respectively. In this way, the position of the second connecting arm can be restricted by the spring. When the second connecting arm is inserted into the hollow cavity of the second frame profile, the fixing threaded hole on the second connecting arm can be aligned with the fixing through hole on the second frame profile. This facilitates the screwing into the fixing threaded hole to fix the second connecting arm and the second frame profile, and also ensures that the connecting screw 223 maintains continuous tightening performance.

[0009] A preferred embodiment of the above technical solution is as follows: the first and second frame profiles each include multiple hollow cavities. Two corner connectors are respectively disposed in the inner and outer hollow cavities of the first and second frame profiles. In the inner hollow cavity, the second connecting arm is fixedly connected to either the second or first frame profile. In the outer hollow cavity, the second connecting arm is fixedly connected to either the first or second frame profile. In this way, the wider frame profiles can be firmly connected and fixed using the two corner connectors. Furthermore, the inner and outer sides of the mating surfaces can be fine-tuned using the corner connectors, effectively reducing or eliminating misalignment at the door and window frame mating surfaces. Additionally, because the connecting blocks are positioned in different directions—that is, the second connecting arms are disposed in different frame profiles in the inner and outer hollow cavities—the mating surfaces can be fine-tuned in different directions, further reducing or eliminating misalignment at the door and window frame mating surfaces.

[0010] A preferred embodiment of the above technical solution is as follows: The first and second frame profiles are provided with filling holes for filling adhesive into the interior of the first and second frame profiles. The filling holes are located at the ends where the first through holes are located, and are closer to the end edges of the first and second frame profiles than the first through holes. Thus, after the first and second frame profiles are fixedly connected by corner connectors, filling them with adhesive through the filling holes allows for a more secure fixation and also provides a sealing effect. When filling the first and second frame profiles with adhesive, the first through holes also serve as observation holes. When adhesive is observed in the first through holes, it indicates that most of the space inside the first and second frame profiles is filled with adhesive. At this point, filling can be stopped, and the frame profiles can be left to stand until the adhesive cures.

[0011] A preferred embodiment of the above technical solution is as follows: It further includes a fixing plate disposed on the surface of the first frame profile and the second frame profile. The fixing plate is fixedly connected to the corner connector, the first frame profile, and the second frame profile by the fixing screws. The fixing plate has a third through hole corresponding to the gap and a fourth through hole corresponding to the filling hole. The diameter of the third through hole is larger than the diameter of the adjusting screw. When using the fixing plate, the fixing plate, the corner connector, the first frame profile, and the second frame profile are temporarily fixed by the fixing screws. When using the connecting block including the first connecting arm and the second connecting arm, the connecting screws are rotated to fine-tune the joint surface. After the misalignment is adjusted, the fixing screws are tightened to firmly fix the fixing plate, the corner connector, the first frame profile, and the second frame profile. Finally, the adjusting screw 24 is inserted into the gap 23 between the corner arm 211 and the first connecting arm 221 to further adjust the misalignment of the joint surface. In this way, the first frame profile and the second frame profile can be more firmly fixed by the fixing plate.

[0012] A preferred embodiment of the above technical solution is that the ends of the first frame profile and the second frame profile are bonded together with an adhesive. This makes the joint between the first frame profile and the second frame profile more secure and also provides a sealing effect.

[0013] The preferred embodiment of the above technical solution is that the included angle between the first frame profile and the second frame profile is 90°.

[0014] The present invention also provides an assembly method for assembling the first frame profile and the second frame profile described above, comprising the following steps in sequence:

[0015] S1. Insert a corner arm of a corner connector and a first or second connecting arm of a connector into the outer hollow cavity of the first frame profile.

[0016] S2. Insert one corner arm of the corner block of another corner connector and the second or first connecting arm of the connecting block into the inner hollow cavity of the first frame profile.

[0017] S3. Temporarily fix the first frame profile and the two corner connectors with fixing screws;

[0018] S4. Align and splice the second frame profile with the first frame profile, so that the exposed portions of the two corner connectors from the first frame profile are respectively inserted into the outer hollow cavity and the inner hollow cavity of the second frame profile;

[0019] S5. Temporarily fix the second frame profile and the two corner connectors with fixing screws;

[0020] S6. Rotate the screw head of the connecting screw of the second connecting arm exposed from the opening to adjust the relative position of the first frame profile and the second frame profile so that the mating surfaces of the first frame profile and the second frame profile are not misaligned and are aligned with each other.

[0021] S7. Tighten the fixing screws to securely fix the corner connector, the first frame profile, and the second frame profile.

[0022] S8. Insert the adjusting screw into the gap between the corner arm and the first connecting arm through the first through hole, so that the corner block is pressed against the inner wall of the hollow cavity of the first frame profile and the second frame profile.

[0023] The preferred embodiment of the above assembly method is:

[0024] In step S3, a fixing plate is provided on the surface of the first frame profile, and the fixing plate, the first frame profile and the two corner connectors are temporarily fixed by fixing screws;

[0025] In step S5, the fixing plate, the second frame profile, and the two corner connectors are temporarily fixed by the fixing screws.

[0026] The preferred embodiment of the above assembly method is:

[0027] The method also includes step S9, in which adhesive is filled into the first frame profile and the second frame profile through the filling holes provided on the first frame profile and the second frame profile. When the first through hole provided on the first frame profile and the second frame profile is filled with adhesive, the filling of adhesive is stopped and the frame profile is left to stand until the adhesive cures.

[0028] As described above, the doors and windows and their assembly method according to the present invention have the following beneficial effects:

[0029] The door and window provided by the present invention can reduce or eliminate the splicing misalignment of the splicing surfaces of the splicing frame profiles when splicing the door and window frames, thereby giving the door and window an aesthetic appearance and ensuring the normal closing function of the door and window.

[0068] like Figures 1 to 4As shown, the door and window involved in this application includes a door and window frame 10 composed of multiple frame profiles with hollow cavities. The door and window frame 10 includes a first frame profile 11 and a second frame profile 12 inclined relative to the first frame profile 11. The ends of the first frame profile 11 and the second frame profile 12 are fixedly connected by corner connectors 20. The corner connectors 20 are disposed in the hollow cavities of the first frame profile 11 and the second frame profile 12 and are fixedly connected to the first frame profile 11 and the second frame profile 12 by fixing screws 40. Specifically, the end faces of the first frame profile 11 and the second frame profile 12 are beveled. After the ends of the first frame profile 11 and the second frame profile 12 are fixedly connected by the corner connectors 20, the second frame profile 12 is inclined relative to the first frame profile 11. The angle of inclination between the first frame profile 11 and the second frame profile 12 can be set to 90°, 120°, etc., according to actual needs.

[0069] like Figure 4 and Figure 7 As shown, the corner connector 20 includes a corner block 21, a connecting block 22, and an adjusting screw 24. The corner block 21 includes two corner arms 211, which are respectively disposed in the hollow cavities of the first frame profile 11 and the second frame profile 12, and are parallel to the first frame profile 11 and the second frame profile 12. The connecting block 22 includes two connecting arms connected at their ends, which are respectively disposed in the hollow cavities of the first frame profile 11 and the second frame profile 12, located outside the two corner arms 211, and are parallel to the first frame profile 11 and the second frame profile 12. A gap 23 is provided between the corner arm 211 and the connecting arm disposed outside the corner arm 211 for inserting the adjusting screw 24. The first frame profile 11 and the second frame profile 12 are provided with first through holes 13 corresponding to the gap 23. By inserting the adjusting screw 24 into the gap 23 through the first through hole 13, the corner block 21 is pressed against the inner wall of the hollow cavity of the first frame profile 11 and the second frame profile 12. In addition, the two connecting arms are respectively provided with fixing thread holes for threaded connection with fixing screws 40, and the first frame profile 11 and the second frame profile 12 are respectively provided with fixing through holes for the fixing screws 40 to pass through.

[0070] In other words, during the assembly of door and window frames, the ends of the first frame profile 11 and the second frame profile 12 are connected by using corner connectors 20, thereby splicing the first frame profile 11 and the second frame profile 12 together. Specifically, as follows... Figure 4 , Figures 7 to 9As shown, during assembly, one corner arm 211 of the corner block 21 and one connecting arm of the connecting block 22 are inserted into the hollow cavity of the first frame profile 11, and the corner block 21 is temporarily fixed to the first frame profile 11 with fixing screws 40. Then, the other corner arm 211 of the corner block 21 and the other connecting arm of the connecting block 22 are inserted into the hollow cavity of the second frame profile 12, and the corner block 21 is temporarily fixed to the second frame profile 12 with fixing screws 40. After splicing the ends of the first frame profile 11 and the second frame profile 12, the fixing screws 40 are tightened. Then, the adjusting screws 24 are inserted into the gap 23 through the first through hole 13 on the first frame profile 11 and the second frame profile 12. Thus, the ends of the first frame profile 11 and the second frame profile 12 are fixedly connected by the corner connectors 20. When the adjusting screw 24 is inserted, it presses against the corner arm 211 and the connecting arm, thereby pressing the corner arm 211 against the inner wall of the hollow cavity of the first frame profile 11 and the second frame profile 12. This allows the ends of the first frame profile 11 and the second frame profile 12 to move slightly in the joint direction, achieving fine-tuning of the joint surface. This reduces or eliminates misalignment of the door and window frame joint surfaces, giving the doors and windows an aesthetically pleasing appearance and ensuring their normal closing function. It should be noted that the temporary fixing described in this application refers to a state where the screw is mostly screwed into the threaded hole, and the component fixed by the screw can only move slightly. Furthermore, a gap 23 is provided between each corner arm 211 and the connecting arm located on its outer side. Depending on actual needs, the adjusting screw 24 can be inserted into both gaps 23, or only into one of the gaps 23. The adjusting screw 24 is preferably a countersunk screw.

[0071] Preferably, such as Figure 7 As shown, the corner block 21 includes two corner arms 211 arranged at opposite angles. The connection between the two corner arms 211 forms the corner of the corner block 21. An avoidance part 212 is provided at the inner corner of the corner block 21, which is a notch formed by cutting off a portion of the inner corner. In this way, when the corner block 21 is pressed against the inner wall of the hollow cavity of the first frame profile 11 and the second frame profile 12, the avoidance part 212 can prevent interference between the inner corner of the corner block 21 and the connection part of the frame profile. This allows for better fine-tuning of the joint surface and reduces or eliminates the splicing misalignment of the door and window frame joint surfaces.

[0072] Furthermore, the connecting block 22 can be a single-piece molded part, or it can be a separate structure in which the ends of two connecting arms are connected together by other components. Preferably, as shown below... Figure 3 , Figure 4 , Figures 7 to 9As shown, the connecting block 22 includes a first connecting arm 221 and a second connecting arm 222, which are spaced apart. The first connecting arm 221 has a threaded hole 221a at one end near the second connecting arm 222, and the second connecting arm 222 has a second through hole 222a corresponding to the threaded hole 221a. A connecting screw 223 is sequentially inserted into the second through hole 222a and the threaded hole 221a. The end of the connecting screw 223 either terminates in or exits from the threaded hole 221a. The first connecting arm 221 and the second connecting arm 222 are fixedly connected to the first frame profile 11 and the second frame profile 12 by fixing screws 40. The first frame profile 11 and / or the second frame profile 12 have openings 14, through which the screw head 223a of the connecting screw 223 protrudes. An adjusting screw 24 is inserted into the gap 23 between the corner arm 211 and the first connecting arm 221. In this way, the misalignment of the splicing surfaces of the door and window frames can be further reduced or eliminated through the combined action of the connecting block 22 and the adjusting screw 24. Specifically, before splicing the frame profiles, the first connecting arm 221 and the second connecting arm 222 are assembled together using connecting screws 223. When splicing the frame profiles, the two corner arms 211 of the corner block 21 and the first connecting arm 221 and the second connecting arm 222 of the connecting block 22 are inserted into the hollow cavities of the first frame profile 11 and the second frame profile 12 respectively and temporarily fixed with fixing screws 40. Then, the screw head 223a of the connecting screw 223 exposed from the opening 14 is rotated, and the connecting screw 223 pushes the second connecting arm 222 towards the first connecting arm 221, which can also drive the end of the first frame profile 11 fixedly connected to the first connecting arm 221 to move slightly in the joint direction to achieve the purpose of fine adjustment of the joint surface. Then, the fixing screw 40 is tightened, and then the adjusting screw 24 is inserted into the gap 23 between the corner arm 211 and the first connecting arm 221 to further adjust the splicing misalignment of the joint surfaces of the first frame profile 11 and the second frame profile 12. This further reduces or eliminates misalignment at the joint surfaces of door and window frames, resulting in a more aesthetically pleasing appearance and ensuring proper closure. Additionally, an adjustment hole can be provided at the end of the screw head 223a, allowing the connecting screw 223 to rotate by inserting a wrench, screwdriver, or other adjusting tool into the adjustment hole protruding from the opening 14.

[0073] Preferably, such as Figure 7As shown, a spring 224 can also be fitted onto the connecting screw 223, with the spring 224 positioned between the first connecting arm 221 and the second connecting arm 222, i.e., both ends of the spring 224 abut against the first connecting arm 221 and the second connecting arm 222 respectively. In this way, the position of the second connecting arm 222 can be restricted by the spring 224. When the second connecting arm 222 is inserted into the hollow cavity of the second frame profile 12, the fixing threaded hole on the second connecting arm 222 can be aligned with the fixing through hole on the second frame profile 12, facilitating the insertion of the fixing screw 40 into the fixing hole to fix the second connecting arm 222 and the second frame profile 12, and ensuring the connecting screw 223 maintains continuous tightening performance. Furthermore, the threaded hole 221a is a through hole, and the first connecting arm 221 and the second connecting arm 222 have an axisymmetric structure. Thus, the connection direction of the first connecting arm 221 and the second connecting arm 222 is not limited. When the connecting block 22 is inserted into the hollow cavity of the frame profile, the first connecting arm 221 or the second connecting arm 222 can be inserted into the hollow cavity of the first frame profile 11 according to actual needs, making the assembly method more flexible.

[0074] Furthermore, when the frame profile is narrow, a corner connector 20 can be used to fix the ends of the two frame profiles together. When the frame profile is wide, two corner connectors 20 can also be used to fix the ends of the two frame profiles together. Specifically, as shown... Figures 1 to 4 , Figure 8 , Figure 9 As shown, the first frame profile 11 and the second frame profile 12 include multiple hollow cavities. Two corner connectors 20 are respectively disposed in the inner and outer hollow cavities of the first frame profile 11 and the second frame profile 12. In the inner hollow cavity, the second connecting arm 222 is fixedly connected to the second frame profile 12, and in the outer hollow cavity, the second connecting arm 222 is fixedly connected to the first frame profile 11. Alternatively, the second connecting arm 222 can be fixedly connected to the first frame profile 11 in the inner hollow cavity and to the second frame profile 12 in the outer hollow cavity. In this way, the wider frame profiles can be firmly connected and fixed using the two corner connectors 20, and the inner and outer sides of the mating surfaces can be finely adjusted using the corner connectors 20, effectively reducing or eliminating misalignment at the joint surfaces of the door and window frames. In addition, since the connecting blocks 22 are set in different directions, that is, in the inner hollow cavity and the outer hollow cavity, the second connecting arm 222 is set in different frame profiles, so that the joint surface can be finely adjusted in different directions, thereby better reducing or eliminating the splicing misalignment of the door and window frame joint surfaces.

[0075] Preferably, such as Figure 3 , Figure 5As shown, the first frame profile 11 and the second frame profile 12 are also provided with filling holes 15 for filling adhesive into the interior of the first frame profile 11 and the second frame profile 12. The filling holes 15 are located at the ends of the first through holes 13 in the first frame profile 11 and the second frame profile 12, and are closer to the end edges of the first frame profile 11 and the second frame profile 12 than the first through holes 13. Thus, after the first frame profile 11 and the second frame profile 12 are fixedly connected by the corner connector 20, filling adhesive into the interior of the first frame profile 11 and the second frame profile 12 through the filling holes 15 can make the first frame profile 11 and the second frame profile 12 more firmly fixed, and also play a sealing role. When filling the first frame profile 11 and the second frame profile 12 with adhesive, the first through hole 13 also serves as an observation hole. When adhesive is observed in the first through hole 13, it indicates that most of the space inside the first frame profile 11 and the second frame profile 12 is filled with adhesive. At this point, filling with adhesive can be stopped, and the frame profiles can be left to stand until the adhesive cures. Additionally, when splicing the first frame profile 11 and the second frame profile 12, adhesive can be applied to the end faces of the first frame profile 11 and the second frame profile 12 to make the splice more secure and also to provide a sealing effect.

[0076] Furthermore, such as Figure 1-3 , Figure 6 , Figure 8 , Figure 9As shown, a fixing plate 30 can also be provided on the surface of the first frame profile 11 and the second frame profile 12. The fixing plate 30 is fixedly connected to the corner connector 20, the first frame profile 11 and the second frame profile 12 by fixing screws 40. The fixing plate 30 is provided with a third through hole 31 corresponding to the gap 23, a fourth through hole 32 corresponding to the filling hole 15, an observation hole corresponding to the first through hole 13 and a receiving hole for accommodating the fixing screws 40. The diameter of the third through hole 31 is larger than the diameter of the adjusting screw 24, and the diameter of the receiving hole is larger than the diameter of the fixing screws 40. When using the fixing plate 30, the fixing plate 30, corner connector 20, first frame profile 11, and second frame profile 12 are temporarily fixed using the fixing screws 40. When using the connecting block 22, which includes the first connecting arm 221 and the second connecting arm 222, the connecting screws 223 are rotated to fine-tune the mating surfaces. After the misalignment is adjusted, the fixing screws 40 are tightened to firmly fix the fixing plate 30, corner connector 20, first frame profile 11, and second frame profile 12. Finally, the adjusting screws 24 are inserted into the gap 23 between the corner arm 211 and the first connecting arm 221 to further adjust the misalignment of the mating surfaces. In this way, the first frame profile 11 and second frame profile 12 can be more firmly fixed using the fixing plate 30. Furthermore, the fixing plate 30 can be any shape capable of being fixedly connected to both the first frame profile 11 and the second frame profile 12 simultaneously, preferably an L-shaped, one-piece metal part.

[0077] like Figure 8 , Figure 9 As shown, the assembly method of the first frame profile 11 and the second frame profile 12 of the above-mentioned doors and windows is as follows:

[0078] Step 1: Insert the corner arm 211 of the corner block 21 of the corner connector 20 and the first connecting arm 221 or the second connecting arm 222 of the connecting block 22 into the outer hollow cavity of the first frame profile 11.

[0079] Step 2: Insert one corner arm 211 of the corner block 21 of the other corner connector 20 and the second connecting arm 222 or the first connecting arm 221 of the connecting block 22 into the inner hollow cavity of the first frame profile 11.

[0080] Step 3: Install a fixing plate 30 on the surface of the first frame profile 11, and temporarily fix the fixing plate 30, the first frame profile 11 and the two corner connectors 20 with fixing screws 40.

[0081] Step 4: Apply adhesive to the end faces of the first frame profile 11 and the second frame profile 12, align and splice the second frame profile 12 with the first frame profile 11, so that the exposed portions of the two corner connectors 20 from the first frame profile 11 are respectively inserted into the outer hollow cavity and the inner hollow cavity of the second frame profile 12.

[0082] Step 5: Temporarily fix the fixing plate 30, the second frame profile 12 and the two corner connectors 20 with fixing screws 40.

[0083] Step 6: Rotate the screw head 223a of the connecting screw 223 exposed from the opening 14 to adjust the relative position of the first frame profile 11 and the second frame profile 12 so that the mating surfaces of the first frame profile 11 and the second frame profile 12 are not misaligned and are aligned with each other.

[0084] Step 7: Tighten the fixing screws 40 to secure the corner connector 20, the first frame profile 11, and the second frame profile 12.

[0085] Step 8: Insert the adjusting screw 24 through the first through hole 13 into the gap 23 between the corner arm 211 and the first connecting arm 221, so that the corner block 21 presses against the inner wall of the hollow cavity of the first frame profile 11 and the second frame profile 12 (see the annotation above).

[0086] Step 9: Fill the first frame profile 11 and the second frame profile 12 with adhesive through the filling hole 15, and observe the amount of adhesive filling through the first through hole 13. When the first through hole 13 is filled with adhesive, stop filling the adhesive and let the frame profile stand until the adhesive cures.
