[0002] A glass curtain wall is a new type of maintenance structure for contemporary buildings. The greatest feature it endows to a building is to organically unify factors such as architectural aesthetics, architectural functions, building energy conservation, and building structures, and it is a mark and symbol of modern architecture.

[0003] There are two connection methods between the column and the cross beam of the curtain wall support frame on the outer facade of the existing building curtain wall. One is to use a metal angle code for connection; the other is to use a spring pin for connection; the method of using a metal angle code for connection is one of the main connection forms of the current framed curtain wall. However, during installation, it needs to be processed according to the installation requirements, resulting in problems such as relatively complex processing technology, many installation procedures, high cost, and high labor intensity for the connection form of the metal angle code; for the connection method of the spring pin, there is no need to set a metal angle code, so the process of processing the metal angle code can be omitted, and the installation requirements are lower than those of the connection method of the metal angle code. Therefore, the spring pin method is convenient for processing and easy to disassemble. However, due to structural limitations, it is impossible to directly use a spring pin to connect between the column and the end of the cross beam at the external corner of the curtain wall, which brings obstacles to installation.

[0004] Therefore, it is urgent to design an installation structure for the external corner of a glass curtain wall to overcome one or more of the above-mentioned deficiencies in the prior art. Summary of the Utility Model

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] Such as Figures 1-2As shown in the figure, the utility model provides an installation structure for the external corner of a glass curtain wall, including a column 10, a cross beam 11, an aluminum plate 12, a glass plate 13, and a steel skeleton 14; the column 10 is fixedly connected to the steel skeleton 14, and the aluminum plate 12 is wrapped around the outside of the steel skeleton 14 and fixedly connected to the steel skeleton 14; it is characterized in that: a first angle steel 15 is provided on one side surface of the column 10 facing the cross beam 11, and the two limb edges of the first angle steel 15 are respectively fixedly connected to the side surface of the column 10, the end of the cross beam 11 is connected to the limb back opposite to the first angle steel 15 through a spring pin 16, and a U-shaped steel member 17 is fixedly connected to the other limb back of the first angle steel 15, the end of the glass plate 13 is embedded in the U-shaped steel member 17, and the groove of the aluminum plate 12 is inserted and fixed to one limb edge of a second angle steel 19;

[0022] Specifically, through the setting of the first angle steel 15, the cross beam 11 and the column 10 can be directly connected through the spring pin 16, saving the installation process. Among them, the first angle steel 15 selects an equal-angle steel or an unequal-angle steel according to the included angle between the cross beam 11 and the column 10. The two limb edges of the first angle steel 15 are respectively fixedly connected to the column 10 by welding to fill the gap between the cross beam 11 and the column 10 and provide a connection foundation between the cross beam 11 and the column 10; for the convenience of installing the glass plate 13 and improving the connection stability and firmness at the same time, the glass plate 13 and the U-shaped steel member 17 adopt an insertion connection method. Among them, the U-shaped steel member 17 has a U-shaped groove and is made of steel material to ensure strength. During installation, the end of the glass plate 13 is inserted into the U-shaped steel member 17 and fixed to realize the clamping and fixing of the glass plate 13. The aluminum plate 12 is used for decoration, and the groove of the aluminum plate 12 is inserted and fixed to one limb edge of the second angle steel 17.

[0023] Further, the groove width of the U-shaped steel member 17 is greater than the thickness of the glass plate 13, and a glass cushion block 18 is fixedly provided between the glass plate 13 and the inner side wall of the U-shaped steel member 17;

[0024] Specifically, to avoid direct contact between the glass plate 13 and the U-shaped steel member 17, the groove width of the U-shaped steel member 17 needs to be greater than the thickness of the glass plate 13. After the end of the glass plate 13 is inserted into the U-shaped steel member 17, a glass cushion block 18 is embedded between the glass plate 13 and the inner side wall of the U-shaped steel member 17 to block the contact between the glass plate 13 and the U-shaped steel member 17 and avoid the problem that the glass plate 13 is easily broken when contacting the U-shaped steel member 17; at the same time, adopting the method of the glass cushion block 18 helps to facilitate the fixing operation of the glass plate 13 and will not perform a destructive operation on the glass plate 13, ensuring the integrity of the glass plate 13.

[0025] Further, in this embodiment, a second angle steel 19 is fixedly connected to one end of the aluminum plate 12 adjacent to the glass plate 13, and the U-shaped steel member 17 is fixedly connected to the end of the second angle steel 19 away from the aluminum plate 12;

[0026] Specifically, one limb back of the second angle steel 19 and the side of the U-shaped steel member 17 away from the first angle steel 15 are fixedly connected together by welding. The limb side of the second angle steel 19 away from the U-shaped steel member 17 is fixedly connected to the aluminum plate 12, and the second angle steel 19 supports and connects the aluminum plate 12 through the U-shaped steel member 17.

[0027] Further, a Z-shaped member 20 is provided on the inner surface of one end of the aluminum plate 12 connected to the second angle steel 19. One side surface of one end of the Z-shaped member 20 is attached to the bottom surface of the aluminum plate 12, and the other end of the Z-shaped member 20 is spaced from the bottom surface of the aluminum plate 12. One limb side of the second angle steel 19 is inserted into the space between the Z-shaped member 20 and the aluminum plate 12;

[0028] Specifically, since the aluminum plate 12 is usually installed last, if the conventional method is used for installation at this time, it will be inconvenient for installation due to insufficient operating space. Therefore, through the setting of the Z-shaped member 20 and using the structural design of the Z-shaped member 20, a slot is formed between the Z-shaped member 20 and the aluminum plate 12, which is convenient for the limb side of the second angle steel 19 away from the U-shaped steel member 17 to be inserted. This replaces the need for the aluminum plate 12 to be separately provided with a sealant joint for fixation in the conventional method, saving costs, making the installation operation simpler, and making the treatment of the internal corner part more reasonable and the appearance better.

[0029] Further, the end of the aluminum plate 12 is spaced from the glass plate 13, and a sealant 21 is filled between the aluminum plate 12 and the glass plate 13;

[0030] Specifically, since the aluminum plate 12 is not used as a load-bearing member, the connection between the aluminum profile and the second angle steel 19 can be adhesively fixed by using the sealant 21, and at the same time, the gap between the aluminum plate 12 and the glass plate 13 can be sealed to improve the aesthetics.

[0031] On the other hand, the present application also provides a construction method, including the following steps:

[0032] S1. Fabricate the glass and the construction materials of the aluminum plate 12 according to the design requirements, and prepare the operating platform, equipment and tools; then install the column 10 using a hoisting device, determine the installation position of the first angle steel 15 on the column 10 using a level, and make a mark to determine the accurate position;

[0033] S2. Press the spring pin 16 into both sides of the end of the crossbeam 11. According to the positions marked in step S1, temporarily weld and fix the two limb sides of the first angle steel 15 to the column 10. Subsequently, align the spring pin and press it into the pre-processed connection hole positions in the limb back of the first angle steel 15 opposite to the crossbeam 11. Insert the spring pin 16 into the hole positions to complete the connection between the crossbeam 11 and the column 10.

[0034] S3. Attach the U-shaped steel member 17 to the limb back of the first angle steel 15 where no holes are opened according to the design requirements, and perform welding and fixation.

[0035] S4. Fit one limb back of the second angle steel 19 to the side surface of the U-shaped steel member 17, and weld the two fitted structural members.

[0036] S5. Pre-process and weld the angle steel profiles into the steel skeleton 14 according to the installation requirements. Then, use a hoisting device to lift the steel skeleton 14 to the connection part of the column 10, check the connection positions, and then perform welding. Weld and fix the contact part between the first angle steel 15 and the steel skeleton 14 together.

[0037] S6. Insert the glass sheet 13 into the groove of the U-shaped steel member 17, adjust the position to ensure that the horizontal deviation of the glass is within the allowable range. After all the glass is adjusted, check the flatness of the overall elevation. Then, press glass pads 18 into the gaps between the glass sheet 13 and the inner sidewall of the U-shaped steel member 17 to fix the glass sheet 13.

[0038] S7. First, fixedly connect a Z-shaped part 20 to the inner surface of one end of the aluminum plate 12 adjacent to the glass sheet 13 in the factory. During on-site installation, align the gap between the Z-shaped part 20 and the aluminum plate 12 and insert it opposite to the limb side of the second angle steel 19 away from the connection with the U-shaped steel member 17. Subsequently, fix the aluminum plate 12 on the outer surface of the steel skeleton 14 with self-tapping screws.

[0039] S8. Before caulking, wipe the caulking parts of the glass and the aluminum plate 12 clean with "xylene" or industrial ethanol and a clean towel. Stuff the gap between the side of the butt-jointed glass and the aluminum plate 12 tightly with a foam rod to ensure straightness, and reserve a caulking thickness of 8 - 12 mm in net height. Before caulking, paste protective adhesive tape on the parts that need to be caulked, and pay attention to keeping the adhesive tape straight with the caulking seam. When caulking, it should be continuous and uniform. After the glue is filled, check whether there are air bubbles, voids, broken seams, inclusions inside. If there are, they should be dealt with in a timely manner. After the glass glue is trimmed, quickly remove the tape pasted on the glass. After the glass glue cures, clean the inner and outer glass and make protection signs.

[0040] In summary, through the provision of the first angle steel in this application, rapid connection between the column and the cross beam is achieved, with a reasonable structure and simple installation, and installation support points for the glass curtain wall are provided; through the U-shaped design of the U-shaped steel member, clamping and fixing of the glass plates are realized, solving the difficulties of the reliability and safety of the fixing of the internal corner of the glass panel, enhancing the safety of the structure, and at the same time providing a connection fulcrum for the aluminum plate; by providing Z-shaped members in the aluminum plate to form a slot structure, the traditional method of separately providing a glue joint in the aluminum plate is replaced, saving costs, with more reasonable treatment of the internal corner part and better appearance.

[0041] The present utility model is not limited solely to what is described in the specification and embodiments. Therefore, additional advantages and modifications can be easily achieved by those skilled in the art. Thus, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present utility model is not limited to specific details, representative devices, and the illustrated examples shown and described herein.
