Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and in particular to a door and window and an assembling method thereof. Background Art

[0002] With the rapid development of urban construction, the facade design of buildings has received more and more attention. More and more buildings use glass curtain walls or large open balconies to enhance the design sense of the building facade. Glass curtain walls or large open balconies require large-sized doors and windows. In order to further enhance the design sense, some doors and windows are spliced ​​at a certain angle so that two or more sides of the building facade are designed with glass. However, large-sized doors and windows have the problem of difficulty in handling and transportation due to the large size of the doors and windows or the doors and windows are multi-sided doors and windows spliced ​​at a certain angle. To solve this problem, the existing large-sized doors and windows mostly adopt a split design. After the various parts of the large-sized doors and windows are transported to the construction site separately, the two frame profiles are spliced ​​and assembled through connectors. In particular, when the two frame profiles of the door and window frame need to be spliced ​​at a certain angle, connectors are usually used to splice the two frame profiles together at a certain angle. However, the 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 spliced ​​frame profiles are prone to splicing misalignment, and the existing connecting parts cannot reduce or eliminate the splicing misalignment of the joint surfaces, thus affecting the appearance of the doors and windows and the normal closing of the doors and windows. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a door and window, which can reduce or eliminate the splicing misalignment of the joint surfaces of the splicing frame profiles when splicing the door and window frames, so that the door and window have an aesthetically pleasing appearance and can ensure the normal closing function of the door and window.

[0004] To achieve the above-mentioned object, the present invention provides a door and window, comprising a door and window frame composed of a plurality of frame profiles with hollow cavities, the door and window frame comprising a first frame profile and a second frame profile arranged obliquely relative to the first frame profile, the ends of the first frame profile and the second frame profile being fixedly connected by a corner connector, the corner connector being arranged in the hollow cavities of the first frame profile and the second frame profile, and being fixedly connected to the first frame profile and the second frame profile by fixing screws, the corner connector comprising a corner assembly block, a connecting block and an adjusting screw, the corner assembly block comprising two corner assembly arms, the two corner assembly arms being respectively arranged in the hollow cavities of the first frame profile and the second frame profile, The connecting block comprises two connecting arm portions connected at the ends, the two connecting arm portions are respectively arranged in the hollow cavity of the first frame profile and the second frame profile, located on the outside of the two corner grouping arm portions, and parallel to the first frame profile and the second frame profile, a gap for inserting the adjusting screw is provided between the corner grouping arm portion and the connecting arm portion arranged on the outside of the corner grouping arm portion, a first through hole corresponding to the gap is provided on the first frame profile and the second frame profile, and the corner grouping block is pressed against the inner wall of the hollow cavity of the first frame profile and the second frame profile by inserting the adjusting screw from the first through hole into the gap.

[0005] When assembling the door and window frames, insert one corner assembly arm of the corner assembly block and one connecting arm of the connecting block into the hollow cavity of the first frame profile and fix the corner assembly block to the first frame profile with a fixing screw, then insert another corner assembly arm of the corner assembly block and another connecting arm of the connecting block into the hollow cavity of the second frame profile and fix the corner assembly block to the second frame profile with a fixing screw, and then insert the adjusting screw into the gap from the first through hole on the first frame profile and the second frame profile. Thus, the ends of the first frame profile and the second frame profile are fixedly connected by the corner connector. When the adjusting screw is inserted, it will squeeze the corner assembly arm and the connecting arm, and then the corner assembly arm will be pressed against the inner wall of the hollow cavity of the first frame profile and the second frame profile, so that the ends of the first frame profile and the second frame profile can be pushed to move slightly in the joining direction, so as to achieve the purpose of fine-tuning the joining surface, thereby reducing or eliminating the splicing misalignment of the door and window frame joining surface, so that the door and window have a beautiful appearance and ensure the normal closing function of the door and window.

[0006] A preferred embodiment of the above technical solution is: the connecting block includes a first connecting arm portion and a second connecting arm portion spaced apart from the first connecting arm portion, the first connecting arm portion is provided with a threaded hole at one end close to the second connecting arm portion, the second connecting arm portion is provided with a second through hole corresponding to the threaded hole, the connecting screw is inserted into the second through hole and the threaded hole in sequence, the first connecting arm portion and the second connecting arm portion are fixedly connected to the first frame profile and the second frame profile through the fixing screw, the first frame profile and / or the second frame profile are provided with an opening portion, the screw head of the connecting screw is exposed from the opening portion, and the adjusting screw is inserted into the gap between the angle arm portion and the first connecting arm portion.

[0007] Before splicing the frame profiles, the first connecting arm and the second connecting arm are assembled together with connecting screws. When splicing the frame profiles, the two corner assembly arms of the corner assembly block and the first connecting arm and the second connecting arm of the connecting block are respectively inserted into the hollow cavities of the first frame profile and the second frame profile and fixed with fixing screws. At this time, the fixing screws are not tightened. Then the screw head of the connecting screw exposed from the opening is rotated, and the connecting screw pushes the second connecting arm to move toward the first connecting arm, which can also drive the end of the first frame profile fixedly connected to the first connecting arm to move slightly in the joining direction, so as to achieve the purpose of fine-tuning the joining surface, and then tighten the fixing screw, and then insert the adjusting screw into the gap between the corner assembly arm and the first connecting arm to further adjust the splicing misalignment of the joining surface of the first frame profile and the second frame profile. In this way, the splicing misalignment of the joining surface of the door and window frame can be further reduced or eliminated, so that the door and window have a beautiful appearance and ensure the normal closing function of the door and window.

[0008] The preferred embodiment of the above technical solution is: a spring is sleeved on the connecting screw, and the two ends of the spring are respectively in contact with the first connecting arm and the second connecting arm. In this way, the position of the second connecting arm can be limited by the spring, and 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, so that the fixing screw can be screwed into the fixing threaded hole to fix the second connecting arm and the second frame profile, and the connecting screw 223 can maintain continuous tightening performance.

[0009] The preferred embodiment of the above technical solution is as follows: the first frame profile and the second frame profile include a plurality of hollow cavities, and there are two corner connectors, which are respectively arranged in the inner hollow cavity and the outer hollow cavity of the first frame profile and the second frame profile, in the inner hollow cavity, the second connecting arm is fixedly connected to the second frame profile or the first frame profile, and in the outer hollow cavity, the second connecting arm is fixedly connected to the first frame profile or the second frame profile. In this way, the frame profile with a wider width can be firmly connected and fixed by two corner connectors, and both the inner and outer sides of the joint surface can be fine-tuned by the corner connectors, effectively reducing or eliminating the splicing misalignment of the door and window frame joint surface. In addition, since the setting directions of the connection blocks are different, that is, in the inner hollow cavity and the outer hollow cavity, the second connecting arm is arranged in different frame profiles, so that the joint surface can be fine-tuned in different directions, better reducing or eliminating the splicing misalignment of the door and window frame joint surface.

[0010] The preferred embodiment of the above technical solution is as follows: a filling hole for filling the first frame profile and the second frame profile with adhesive is provided in the first frame profile and the second frame profile, and the filling hole is provided at the end where the first through hole in the first frame profile and the second frame profile is located, and is closer to the end edge of the first frame profile and the second frame profile than the first through hole. In this way, after the first frame profile and the second frame profile are fixedly connected by the corner connector, the first frame profile and the second frame profile are filled with adhesive through the filling hole, so that the first frame profile and the second frame profile can be fixed more firmly and also play a sealing role. When the adhesive is filled into the first frame profile and the second frame profile, the first through hole also plays the role of an observation hole. When the adhesive is observed in the first through hole, it means that most of the space inside the first frame profile and the second frame profile is filled with adhesive. At this time, the adhesive filling can be stopped, and the frame profile is left to stand until the adhesive solidifies.

[0011] The preferred solution of the above technical solution is: it also includes a fixing plate arranged on the surface of the first frame profile and the second frame profile, the fixing plate is fixedly connected with the corner connector, the first frame profile and the second frame profile by the fixing screw, and the fixing plate is provided with a third through hole corresponding to the gap and a fourth through hole corresponding to the filling hole, and the diameter of the third through hole is greater than the diameter of the adjusting screw. When using the fixing plate, firstly temporarily fix the fixing plate, the corner connector, the first frame profile and the second frame profile by fixing screws, and when using the connecting block including the first connecting arm and the second connecting arm, turn the connecting screw to fine-tune the joint surface, and tighten the fixing screw after the splicing misalignment is adjusted to firmly fix the fixing plate, the corner connector, the first frame profile and the second frame profile, and finally insert the adjusting screw 24 into the gap 23 between the corner arm 211 and the first connecting arm 221 to further adjust the splicing 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 by an adhesive, so that the splicing of the first frame profile and the second frame profile is more firm and also has a sealing effect.

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

[0014] The present invention also provides an assembling method of the first frame profile and the second frame profile, and the assembling of the first frame profile and the second frame profile comprises the following steps in sequence:

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

[0020] S6, rotating the screw head of the connecting screw of the second connecting arm exposed from the opening, adjusting the relative position of the first frame profile and the second frame profile, so that the joint surfaces of the first frame profile and the second frame profile are aligned with each other without misalignment;

[0021] S7, tighten the fixing screws to firmly fix the corner connector, the first frame profile and the second frame profile;

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

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

[0025] In the 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-mentioned assembly method is:

[0027] The method further includes step S9, filling the first frame profile and the second frame profile with adhesive through the filling holes provided on the first frame profile and the second frame profile. When the first through holes provided on the first frame profile and the second frame profile are filled with adhesive, the filling of adhesive is stopped and the frame profile is left standing until the adhesive is cured.

[0068] like Figures 1 to 4As shown, the door and window involved in the present application includes a door and window frame 10 composed of a plurality of frame profiles with a hollow cavity, the door and window frame 10 includes a first frame profile 11 and a second frame profile 12 arranged obliquely 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 a corner connector 20, the corner connector 20 is arranged in the hollow cavity of the first frame profile 11 and the second frame profile 12, and is fixedly connected to the first frame profile 11 and the second frame profile 12 by a fixing screw 40. Specifically, the end faces of the ends of the first frame profile 11 and the second frame profile 12 are inclined surfaces, and after the ends of the first frame profile 11 and the second frame profile 12 are fixedly connected by the corner connector 20, the second frame profile 12 is arranged obliquely relative to the first frame profile 11. According to actual needs, the inclined angle between the first frame profile 11 and the second frame profile 12 can be set to 90°, 120°, etc.

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

[0070] That is, when assembling the door and window frame, the first frame profile 11 and the second frame profile 12 are connected by using the corner connector 20, thereby splicing the first frame profile 11 and the second frame profile 12 together. Figure 4 , Figures 7 to 9As shown, during assembly, one corner assembly arm 211 of the corner assembly 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 assembly block 21 is temporarily fixed to the first frame profile 11 by the fixing screw 40, and then the other corner assembly arm 211 of the corner assembly 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 assembly block 21 is temporarily fixed to the second frame profile 12 by the fixing screw 40, and after the ends of the first frame profile 11 and the second frame profile 12 are spliced, the fixing screw 40 is tightened, and then the adjusting screw 24 is inserted into the gap 23 from 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 connector 20. When the adjusting screw 24 is inserted, it will squeeze the corner arm 211 and the connecting arm, so that the corner arm 211 is pressed against the inner wall of the hollow cavity of the first frame profile 11 and the second frame profile 12, and the ends of the first frame profile 11 and the second frame profile 12 can be pushed to move slightly in the joining direction, so as to achieve the purpose of fine-tuning the joining surface, thereby reducing or eliminating the splicing misalignment of the door and window frame joining surface, so that the door and window have a beautiful appearance and ensure the normal closing function of the door and window. It should be noted that the temporary fixation described in this application refers to a state in which most of the screws are screwed into the threaded holes and the parts fixed by the screws can only move slightly. In addition, a gap 23 is provided between each corner arm 211 and the connecting arm located outside thereof. According to actual needs, the adjusting screw 24 can be inserted into both gaps 23, or the adjusting screw 24 can be inserted into only one of the gaps 23. The adjusting screw 24 is preferably a countersunk screw.

[0071] Preferably, if Figure 7 As shown, the corner assembly block 21 includes two corner assembly arms 211 arranged relatively obliquely, the connection of the two corner assembly arms 211 forms the corner of the corner assembly block 21, and an avoidance portion 212 is provided at the inner corner of the corner assembly block 21, and the avoidance portion 212 is a notch formed by cutting off a part of the inner corner. In this way, when the corner assembly 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 portion 212 can avoid interference between the inner corner of the corner assembly block 21 and the connection part of the frame profile, and the joint surface can be fine-tuned better, reducing or eliminating the splicing misalignment of the joint surface of the door and window frames.

[0072] Furthermore, the connecting block 22 may be an integrally formed part, or a separate structure in which the ends of the two connecting arms are connected together through other parts. Figure 3 , Figure 4 , Figures 7 to 9As shown, the connection block 22 includes a first connection arm portion 221 and a second connection arm portion 222, the first connection arm portion 221 and the second connection arm portion 222 are arranged at intervals, a threaded hole 221a is provided at one end of the first connection arm portion 221 close to the second connection arm portion 222, and a second through hole 222a corresponding to the threaded hole 221a is provided in the second connection arm portion 222, and a connection screw 223 is inserted into the second through hole 222a and the threaded hole 221a in sequence, and the end of the connection screw 223 stops in the threaded hole 221a or passes out from the threaded hole 221a, and the first connection arm portion 221 and the second connection arm portion 222 are fixedly connected to the first frame profile 11 and the second frame profile 12 by fixing screws 40. An opening portion 14 is provided on the first frame profile 11 and / or the second frame profile 12, and a screw head 223a of the connection screw 223 is exposed from the opening portion 14, and the adjustment screw 24 is inserted into the gap 23 between the corner arm portion 211 and the first connection arm portion 221. In this way, the joint misalignment of the door and window frame joint surface 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 portion 221 and the second connecting arm portion 222 are assembled together with the connecting screw 223. When splicing the frame profiles, the two corner arm portions 211 of the corner block 21 and the first connecting arm portion 221 and the second connecting arm portion 222 of the connecting block 22 are first inserted into the hollow cavities of the first frame profile 11 and the second frame profile 12 respectively and temporarily fixed with the fixing screw 40. Then, the screw head 223a of the connecting screw 223 exposed from the opening portion 14 is rotated, and the connecting screw 223 pushes the second connecting arm portion 222 to move toward the first connecting arm portion 221, which can also drive the end of the first frame profile 11 fixedly connected to the first connecting arm portion 221 to move slightly in the joining direction, so as to achieve the purpose of fine-tuning the joining surface. Then, the fixing screw 40 is tightened, and then the adjusting screw 24 is inserted into the gap 23 between the corner arm portion 211 and the first connecting arm portion 221 to further adjust the splicing misalignment of the joining surface of the first frame profile 11 and the second frame profile 12. Thus, the splicing misalignment of the joint surface of the door and window frame can be further reduced or eliminated, so that the door and window have a beautiful appearance and the normal closing function of the door and window is ensured. In addition, an adjustment hole can be provided at the end of the screw head 223a, and an adjustment tool such as a wrench or a screwdriver can be inserted into the adjustment hole of the screw head 223a exposed from the opening 14 to drive the connecting screw 223 to rotate.

[0073] Preferably, if Figure 7As shown, a spring 224 can also be sleeved on the connecting screw 223, so that the spring 224 is located between the first connecting arm portion 221 and the second connecting arm portion 222, that is, the two ends of the spring 224 are respectively in contact with the first connecting arm portion 221 and the second connecting arm portion 222. In this way, the position of the second connecting arm portion 222 can be limited by the spring 224, and when the second connecting arm portion 222 is inserted into the hollow cavity of the second frame profile 12, the fixing threaded hole on the second connecting arm portion 222 can be aligned with the fixing through hole on the second frame profile 12, so that it is convenient to insert the fixing screw 40 into the fixing hole to fix the second connecting arm portion 222 and the second frame profile 12, and the connecting screw 223 can maintain continuous fastening performance. In addition, the threaded hole 221a is a through hole, and the first connecting arm portion 221 and the second connecting arm portion 222 are axisymmetric structures. In this way, the connection direction of the first connecting arm portion 221 and the second connecting arm portion 222 is not limited. When the connecting block 22 is inserted into the hollow cavity of the frame profile, the first connecting arm portion 221 or the second connecting arm portion 222 can be selected according to actual needs to be inserted into the hollow cavity of the first frame profile 11, and the assembly method is more flexible.

[0074] Furthermore, when the width of the frame profile is narrow, one corner connector 20 may be used to fix the ends of the two frame profiles together. When the width of the frame profile is wide, two corner connectors 20 may also be used to fix the ends of the two frame profiles together. Specifically, Figures 1 to 4 , Figure 8 , Fig. 9 As shown, the first frame profile 11 and the second frame profile 12 include a plurality of hollow cavities, and there are two corner connectors 20, which are respectively arranged in the inner hollow cavity and the outer hollow cavity of the first frame profile 11 and the second frame profile 12. In the inner hollow cavity, the second connecting arm portion 222 is fixedly connected to the second frame profile 12, and in the outer hollow cavity, the second connecting arm portion 222 is fixedly connected to the first frame profile 11. Alternatively, in the inner hollow cavity, the second connecting arm portion 222 is fixedly connected to the first frame profile 11, and in the outer hollow cavity, the second connecting arm portion 222 is fixedly connected to the second frame profile 12. In this way, the frame profile with a wider width can be firmly connected and fixed by two corner connectors 20, and the inner and outer sides of the joint surface can be fine-tuned by the corner connector 20, effectively reducing or eliminating the splicing misalignment of the joint surface of the door and window frames. In addition, since the connection block 22 is set in different directions, that is, in the inner hollow cavity and the outer hollow cavity, the second connecting arm portion 222 is set in different frame profiles, the joint surface can be fine-tuned in different directions, thereby better reducing or eliminating the splicing misalignment of the door and window frame joint surface.

[0075] Preferably, if Figure 3 , Figure 5As shown, the first frame profile 11 and the second frame profile 12 are further provided with a filling hole 15 for filling the first frame profile 11 and the second frame profile 12 with adhesive, and the filling hole 15 is provided at the end where the first through hole 13 in the first frame profile 11 and the second frame profile 12 is located, and is closer to the end edge of the first frame profile 11 and the second frame profile 12 than the first through hole 13. In this way, after the first frame profile 11 and the second frame profile 12 are fixedly connected by the corner connector 20, the adhesive is filled into the first frame profile 11 and the second frame profile 12 through the filling hole 15, so that the first frame profile 11 and the second frame profile 12 can be fixed more firmly, and also play a sealing role. When the adhesive is filled into the first frame profile 11 and the second frame profile 12, the first through hole 13 also serves as an observation hole. When the adhesive is observed in the first through hole 13, it means that most of the space inside the first frame profile 11 and the second frame profile 12 is filled with the adhesive. At this time, the adhesive filling can be stopped and the frame profile is left to stand until the adhesive solidifies. In addition, when the first frame profile 11 and the second frame profile 12 are spliced, the adhesive can also be applied to the end faces of the first frame profile 11 and the second frame profile 12 to make the splicing of the first frame profile 11 and the second frame profile 12 more firm, and also play a sealing role.

[0076] Furthermore, if Figure 1-3 , Figure 6 , Figure 8 , Fig. 9As shown, a fixing plate 30 can also be set on the surfaces 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 receiving the fixing screw 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 screw 40. When the fixing plate 30 is used, the fixing plate 30, the corner connector 20, the first frame profile 11 and the second frame profile 12 are temporarily fixed by the fixing screws 40. When the connecting block 22 including the first connecting arm 221 and the second connecting arm 222 is used, the connecting screws 223 are rotated to fine-tune the joint surface. After the splicing misalignment is adjusted, the fixing screws 40 are tightened to firmly fix the fixing plate 30, the corner connector 20, the first frame profile 11 and the 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 splicing misalignment of the joint surface. In this way, the first frame profile 11 and the second frame profile 12 can be more firmly fixed by the fixing plate 30. In addition, the fixing plate 30 can be any shape that can be fixedly connected to the first frame profile 11 and the second frame profile 12 at the same time, preferably an L-shaped metal integral molding.

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

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

[0079] Step 2: insert a corner assembly arm 211 of the corner assembly block 21 of another 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: a fixing plate 30 is arranged on the surface of the first frame profile 11 , and the fixing plate 30 , the first frame profile 11 and the two corner connectors 20 are temporarily fixed by fixing screws 40 .

[0081] Step 4: Apply adhesive to the end surfaces 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, and insert the portions of the two corner connectors 20 exposed from the first frame profile 11 into the outer hollow cavity and the inner hollow cavity of the second frame profile 12 respectively.

[0082] Step 5: temporarily fix the fixing plate 30 , the second frame profile 12 and the two corner connectors 20 by 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 joint surfaces of the first frame profile 11 and the second frame profile 12 are aligned with each other without misalignment.

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

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

[0086] Step nine: fill the first frame profile 11 and the second frame profile 12 with adhesive through the filling hole 15, and observe the filling amount of the adhesive 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 solidifies.
