Description

Technical Field

[0001] The present invention relates to a building structure, and in particular to a crossbeam structure of a glass curtain wall and a glass curtain wall. Background Art

[0002] In commercial spaces, due to the strong light transmittance of glass curtain walls, they are widely used in commercial office buildings. In the current glass curtain wall structure, the connection between the columns and the crossbeams is to set angle pieces on the columns and then fix the crossbeams and the angle pieces through self-tapping screws. Currently, the angle piece connection system can be roughly divided into two types: 1. Open-cavity crossbeam; 2. Closed-cavity crossbeam. The open-cavity crossbeam is convenient for construction, but its structural stress is relatively poor and the profile consumption is large; the closed-cavity crossbeam has less material consumption and better structural stress, but its construction difficulty is large (the vertical and horizontal keels must be installed simultaneously). In actual projects, due to poor management, construction workers often use the method of cutting openings on the crossbeam for assembly during the installation of the closed-cavity crossbeam, which not only affects the aesthetics but also brings the problem of weakening the structural safety of the crossbeam. Summary of the Invention

[0003] The purpose of the present invention is to provide a crossbeam structure of a glass curtain wall and a glass curtain wall, and the technical problem to be solved is to make the installation of the crossbeam simpler and shorten the construction time.

[0004] To solve the above problems, the present invention is realized by adopting the following technical solutions: A crossbeam structure of a glass curtain wall includes a crossbeam body. The crossbeam body includes a main crossbeam and a secondary crossbeam. The main crossbeam and the secondary crossbeam are arranged opposite to each other and in contact. At both ends of the main crossbeam, L-shaped connecting arms are respectively provided. At the end of the connecting arm far from the main crossbeam, an installation hole is provided. At one end of the main crossbeam and the secondary crossbeam opposite to each other, a protruding portion is provided to form abutting portions at the upper and lower ends of the main crossbeam. At one end of the secondary crossbeam opposite to the main crossbeam and corresponding to the position of the protruding portion, a concave portion is provided to form inserting portions at the upper and lower ends of the secondary crossbeam. When the concave portion is adaptively connected to the protruding portion, the inserting portion is inserted into the abutting portion; first screw holes and second screw holes are respectively provided on the abutting portion and the inserting portion to enable threaded connection between the main crossbeam and the secondary crossbeam; at one end of the main crossbeam facing away from the secondary crossbeam and corresponding to the position of the protruding portion, a screw rod embedding groove is provided, and the screw rod embedding groove is arranged along the length direction of the main crossbeam; at one end of the main crossbeam facing away from the secondary crossbeam and symmetrically arranged at the upper and lower ends of the screw rod embedding groove, load-bearing arms are provided to carry the glass curtain wall panel.

[0005] Further, edge portions extending towards the main crossbeam are provided at the upper and lower ends of the secondary crossbeam, and the edge portions cover the upper and lower end surfaces of the main crossbeam and the connecting arms.

[0006] Further, first tooth patterns are provided on the surface of one end of the edge portion opposite to the upper and lower end surfaces of the main crossbeam, and second tooth patterns engaged with the first tooth patterns are respectively provided on the upper and lower end surfaces of the main crossbeam.

[0015] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0016] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the present invention discloses a crossbeam structure for a glass curtain wall, including a crossbeam body. The crossbeam body includes a main crossbeam 1 and a secondary crossbeam 2. The main crossbeam 1 and the secondary crossbeam 2 are arranged in relative contact. At both ends of the main crossbeam 1, L-shaped connecting arms 3 are respectively provided. At the end of the connecting arm 3 far from the main crossbeam 1, a mounting hole 4 is provided. At one end of the main crossbeam 1 opposite to the secondary crossbeam 2, a protruding portion 5 is provided. The protruding portion 5 is arranged along the length direction of the main crossbeam 1 to form abutting portions 6 at the upper and lower ends of the main crossbeam 1. At one end of the secondary crossbeam 2 opposite to the main crossbeam 1 and corresponding to the position of the protruding portion 5, a recess 7 is provided to form insertion portions 8 at the upper and lower ends of the secondary crossbeam 2. The recess 7 is arranged along the length direction of the secondary crossbeam 2. When the recess 7 is adaptively connected to the protruding portion 5, the insertion portions 8 are inserted into the abutting portions 6. A plurality of first screw holes 9 and second screw holes 10 are respectively provided on the abutting portions 6 and the insertion portions 8, so that the main crossbeam 1 and the secondary crossbeam 2 are threadedly connected by screws. The first screw holes 9 penetrate through the surface of one end of the main crossbeam 1 far from the secondary crossbeam 2 and the corresponding position of the abutting portion 6. At one end of the main crossbeam 1 facing away from the secondary crossbeam 2 and corresponding to the position of the protruding portion 5, a screw rod embedding groove 11 is provided. The screw rod embedding groove 11 is arranged along the length direction of the main crossbeam 1 and extends to the connecting arms 3 at both ends. At one end of the main crossbeam 1 facing away from the secondary crossbeam 2 and symmetrically arranged at the upper and lower ends of the screw rod embedding groove 11, there are bearing arms 12. The bearing arms 12 extend to the connecting arms 3 at both ends to carry the glass curtain wall panel. Specifically, the protruding portion 5 is provided in the middle of the main crossbeam 1. Correspondingly, the recess 7 is provided in the middle of the secondary crossbeam 2, so that the two abutting portions 6 and the insertion portions 8 are of the same size.

[0017] In the present invention, the first screw holes 9 and the second screw holes 10 are arranged at intervals. Specifically, the first screw holes 9 and the second screw holes 10 are arranged in the middle and the opposite ends of the crossbeam body.

[0018] When installing the main and secondary crossbeams, align the recess 7 of the secondary crossbeam 2 with the protruding portion 5 of the main crossbeam 1 and then insert them into each other. The insertion portions 8 and the abutting portions 6 are inserted into each other. Then, connect and fix the main crossbeam 1 and the secondary crossbeam 2 together by screwing through the first screw holes 9 and the second screw holes 10. Since the secondary crossbeam 2 is not stressed during use, it does not affect the structural safety of the glass curtain wall.

[0019] As Figure 3 shown in the figure, the connecting arm 3 includes a first arm portion 31 parallel to the main crossbeam 1 and a second arm portion 32 perpendicular to the first arm portion 31. The mounting hole 4 is provided on the second arm portion 32. There is an assembly distance between the second arm portion 32 and the main crossbeam 1 to reserve construction space for the installation of the main crossbeam 1. Specifically, the bearing arm 12 extends to the edge of the surface of the end of the second arm portion 32 facing away from the secondary crossbeam 2. Both ends of the screw rod embedding groove 11 extend to the ends of the first arm portions 31 far from the main crossbeam 1 and form screw rod insertion notches.

[0020] In the present invention, both the main cross beam 1 and the auxiliary cross beam 2 are aluminum alloy profiles with hollow inner cavities. Preferably, the first arm portion 31 is an aluminum alloy profile with a hollow inner cavity and a width smaller than that of the main cross beam 1; the second arm portion 32 is a plate-like structure extending towards the auxiliary cross beam 2, and the surface of one end thereof opposite to the main cross beam 1 and the auxiliary cross beam 2 is aligned.

[0021] In the present invention, the length of the auxiliary cross beam 2 is the sum of the lengths of the main cross beam 1 and the two connecting arms 3.

[0022] As Figure 1 、 Figure 3 and Figure 4 shown, at the upper and lower edge ends of the auxiliary cross beam 2, there are edge wrappings 13 extending towards the main cross beam 1. The edge wrappings 13 cover the upper and lower surface ends of the main cross beam 1 and the connecting arms 3, thereby ensuring the aesthetic appearance of the cross beam body; specifically, as Figure 1 shown, on the surface of one end of the edge wrapping 13 opposite to the upper and lower end surfaces of the main cross beam 1, there are first tooth patterns 14, and on the upper and lower end surfaces of the main cross beam 1, there are second tooth patterns 15 that engage with the first tooth patterns 14, so as to make the joint between the main cross beam 1 and the auxiliary cross beam 2 more tight.

[0023] As Figure 1 and Figure 4 shown, at one end of the edge wrapping 13 away from the auxiliary cross beam 2, there is a rubber strip embedding groove 16, and in the rubber strip embedding groove 16, there is a sealing rubber strip 17, so as to abut against the frame of the glass curtain wall panel and play a sealing role.

[0024] As Figure 1 、 Figure 3 and Figure 4 shown, at one end of the two edge wrappings 13 away from the auxiliary cross beam 2 and on the surface of one end where the two edge wrappings 13 face each other, there are protrusions 18. The protrusions 18 are arranged along the length direction of the auxiliary cross beam 2, and at the upper and lower end surfaces of the main cross beam 1 and at positions corresponding to the protrusions 18, there are recessed grooves 19, so that after the main cross beam 1 and the auxiliary cross beam 2 are connected, they are not easily separated, and further make the joint between the two more tight.

[0025] As Figure 1 shown, the present invention also discloses a glass curtain wall, including a column 100 and a glass curtain wall panel 200. The above-mentioned cross beam body is provided on the column 100, which will not be elaborated here.

[0026] In the present invention, the cross beam body is used in a stick-supported glass curtain wall.

[0027] During installation, the main crossbeam 1 is fixedly connected to the reserved screw holes on the column 100 through self-tapping screws passing through the installation holes on the second arm portion 32, so that the main crossbeam 1 is fixed on the column 100. Then, after the auxiliary crossbeam 2 and the main crossbeam 1 are assembled in place, the main crossbeam 1 and the auxiliary crossbeam 2 are fixedly connected by screws passing through the first screw hole 9 and the second screw hole 10. Then, through the prior art, the glass curtain wall panel is fixed on the main crossbeam 1 by the pressing plate 300, and the buckling plate 400 is buckled on the pressing plate 300 by the prior art outside the pressing plate 300.

[0028] By providing the main and auxiliary crossbeams, the present invention provides L-shaped connecting arms at both ends of the main crossbeam for direct connection with the column, which can avoid the need for construction tools such as cavity opening for the crossbeam. Then, the auxiliary crossbeam and the main crossbeam are firmly connected by screws, making the installation of the crossbeam simpler. Without affecting the structural safety of the crossbeam, the construction time is reduced, and the use of the main and auxiliary crossbeams can ensure that the aesthetics of the crossbeam is not affected.
