Description

Technical Field

[0001] The utility model belongs to the field of curtain wall decoration and relates to an anti-twist closed-cavity beam connection structure. Background Art

[0002] When installing a frame-type glass curtain wall, after the glass is installed on the beam, the front end of the beam often twists, causing the beam to be lower in the front and higher in the back, affecting the exterior effect. Over time, it will also affect the stress on the beam, causing deformation of the beam and posing a safety hazard.

[0003] With the development of curtain wall decoration technology, closed-cavity beam technology has been gradually applied. Closed-cavity beams have the advantages of strong torsion resistance and fast construction. In addition, the required cross-sectional area is relatively low, which makes them more economical than traditional open-cavity beam systems. However, when closed-cavity beams and columns are connected by bolts, it is usually necessary to pre-open mounting holes on the columns. After the bolts enter the mounting holes, there is a structural gap between the bolts and the hole wall, which makes the bolts easy to loosen in the mounting holes. When the end of the beam is subjected to force, there is still a certain torsion phenomenon in the connection between the closed-cavity beam and the column. Utility Model Content

[0004] In view of this, an object of the present invention is to provide a torsion-resistant closed-cavity beam connection structure, so as to improve the force-bearing performance of the closed-cavity beam structure and prevent the closed-cavity beam from torsion.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a torsion-proof closed-cavity beam connection structure for connecting an aluminum alloy column and a closed-cavity beam.

[0006] The connection structure also includes an anti-torsion angle code, which has a first plate surface and a second plate surface that are perpendicular to each other. The first plate surface is inserted into the closed cavity beam, and the second plate surface cooperates with the surface of the aluminum alloy column. At least one anti-torsion screw is drilled into the aluminum alloy column through the second plate surface.

[0007] Optionally, the crossbeam angle code is a groove-type structure, including a top plate and a bottom plate arranged opposite to each other, and an assembly plate connecting the two; the open end of the crossbeam angle code cooperates with the closed-cavity crossbeam, and the crossbeam angle code is installed on the surface of the aluminum alloy column through the assembly plate.

[0008] Optionally, the crossbeam angle code is detachably mounted on the aluminum alloy column by means of at least one through screw, and a mounting hole matching with the through screw is provided in the aluminum alloy column.

[0009] Optionally, a limit plate is further provided between the top plate and the bottom plate, and at least one through screw enters the aluminum alloy column through the limit plate and the assembly plate.

[0010] Optionally, at least one docking groove for connecting the closed-cavity crossbeam is provided on the limiting plate, and an extension direction of the docking groove is perpendicular to an insertion direction of the closed-cavity crossbeam.

[0011] Optionally, the feature is that it also includes at least one beam fixing screw, which enters the docking groove from the first side surface of the closed-cavity beam.

[0012] Optionally, the feature is that it also includes at least one auxiliary screw, which passes through the limiting plate and the assembly plate and then drills into the aluminum alloy column.

[0033] like Figure 1 to Figure 7 The utility model provides a torsion-proof closed-cavity beam 2 connection structure, which is used to connect an aluminum alloy column 1 and a closed-cavity beam 2. The connection structure includes a beam angle bracket 3, which is detachably mounted on the surface of the aluminum alloy column 1. A mounting hole is provided in the aluminum alloy column 1, and at least one through screw 4 passes through the beam angle bracket 3 and is inserted into the mounting hole of the aluminum alloy column 1 to fix the beam angle bracket 3 on the aluminum alloy column 1.

[0034] The cross beam bracket 3 is a groove-shaped structure, including a top plate 31 and a bottom plate 33 arranged opposite to each other, and an assembly plate 32 connecting the ends of the two. The cross beam bracket 3 is installed on the surface of the column 1 through the assembly plate 32. The open end of the cross beam bracket 3 is opposite to the closed cavity cross beam 2. The closed cavity cross beam 2 has a cavity 21, and the cross section of the cavity 21 matches the open end of the cross beam bracket 3. The cross beam bracket 3 is customized according to the inner cavity cross section of the closed cavity cross beam 2.

[0035] Furthermore, a limit plate 34 is provided between the top plate 31 and the bottom plate 33, and the limit plate 34 is parallel to the assembly plate 32. At least one through screw 4 passes through the limit plate 34 and the assembly plate 32 and enters the aluminum alloy column 1. Furthermore, at least one docking groove 35 for connecting the closed-cavity beam 2 is provided on the limit plate 34, and the extension direction of the docking groove 35 is perpendicular to the insertion direction of the closed-cavity beam 2.

[0036] The connection structure further includes at least one beam fixing screw 5. The closed-cavity beam 2 has a first side surface 23 and a second side surface 24 opposite to each other. The beam fixing screw 5 penetrates into the docking groove 35 from the first side surface 23 of the closed-cavity beam 2 at a position corresponding to the docking groove 35 to ensure a stable connection between the closed-cavity beam 2 and the beam angle bracket 3.

[0037] The connection structure also includes at least one auxiliary screw 6 disposed below the through screw 4. The auxiliary screw 6 does not need to be pre-drilled, and is directly drilled into the aluminum alloy column 1 after passing through the limit plate 34 and the assembly plate 32. During installation, the cross beam angle bracket 3 is first installed on the surface of the column 1 by the through screw 4 and the auxiliary screw 6, and then the closed-cavity cross beam 2 is inserted into the cross beam angle bracket 3, and then the cross beam fixing screws 5 corresponding to the number of the butt grooves 35 are screwed from the surface of the closed-cavity cross beam 2 into the butt grooves 35 of the cross beam angle bracket 3.

[0038] The connection structure also includes an anti-torsion angle code 8 that connects the closed-cavity beam 2, the beam angle code 3 and the column 1. The anti-torsion angle code 8 is L-shaped and has a first plate surface and a second plate surface that are perpendicularly connected to each other. The second side surface 24 of the closed-cavity beam 2 is provided with a limiting groove 22 that is recessed into the cavity 21. The first plate surface of the anti-torsion angle code 8 matches the limiting groove 22, and the second plate surface matches the surface of the aluminum alloy column 1. The anti-torsion screw 9 is directly inserted into the aluminum alloy column 1 from the second plate surface. The anti-torsion angle code 8 is embedded in the limiting groove 22. When the beam angle code 3 has a tendency to rotate, the torsional force will act on the limiting groove 22 through the anti-torsion angle code 8, thereby limiting the torsion of the beam angle code 3, thereby avoiding the torsion phenomenon of the front end of the beam.

[0039] The connection structure also includes a crossbeam buckle cover 7, which is buckled on the first side surface 23 of the closed-cavity crossbeam 2 to cover the crossbeam fixing screws 5 and improve the aesthetics.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
