Description

Technical Field

[0001] The invention relates to the technical field of building curtain walls, in particular to a curtain wall frame closed-cavity beam connecting device. Background Art The existing curtain wall frame beams mainly use the following three connection methods: semi-closed cavity beams use angle code connection, spring pin and nail combination connection, and pin connection. The main defects of the existing connection technology are as follows: The main disadvantages of angle bracket connection are: 1. The crossbeam must be open or semi-open, and its bearing capacity is weak. At the same time, the open-cavity design of the crossbeam requires an additional buckle cover design, so that there will be natural gaps in the crossbeam, and its appearance is poor; 2. The torsional bearing capacity of the connecting angle bracket is weak. When the glass panel is greater than 100kg, the end of the crossbeam will be severely twisted.

[0002] The main disadvantages of the combined connection of the spring pin method and nailing are: 1. The scope of use is limited. For example, in some areas, there is a restriction that the connection cannot be higher than 50m; 2. The spring pin and nail cannot bear the force together at the same time.

[0003] The main disadvantages of the pin connection are: 1. The scope of use is limited. For example, in some areas, there is a restriction that the connection cannot be higher than 50m. 2. Due to the use of the plug-in method, the openings on the side walls of the columns are relatively large. When the glass panel is heavy, the torsion of the beam ends is more serious. Summary of the Invention

[0024] In this embodiment, Figure 1 As shown, the adapter 1 is a T-shaped structure, and a clamping plate is provided at the first end of the adapter 1, and the clamping plate is arranged perpendicular to the first end. A first clamping block and a second clamping block are provided at the second end of the adapter 1, and a clamping groove is formed between the first clamping block and the second clamping block. The clamping groove is clamped with the protrusion 6 on the first side wall of the beam 3, so that the beam 3 and the adapter 1 are firmly connected.

[0025] like Figure 1 As shown, in an optional embodiment of the present invention, the clamping plate is fixedly connected to the crossbeam 3 via a machine nail 5 .

[0026] In this embodiment, Figure 1 As shown, after the crossbeam 3 and the adapter 1 are installed and connected, a machine nail 5 is used to fix the card plate of the adapter 1, so that the card plate and the crossbeam 3 are firmly connected together, making the installation more secure. The preferred model of the machine nail 5 is M5x12.

[0031] like Figure 1 As shown, in an optional embodiment of the present invention, the adapter 1 is fixedly connected to the curtain wall keel column 2 by at least one bolt 4.

[0032] In this embodiment, Figure 1 As shown, the adapter 1 is fixed to the curtain wall keel column 2 by at least one bolt 4, so as to provide a firm support force for the beam 3 mounted on the adapter 1, and the preferred bolt model is M6x150.

[0033] In an optional embodiment of the present invention, the at least one bolt 4 is made of stainless steel.

[0034] In this embodiment, the bolt 4 is made of stainless steel, which has the characteristics of corrosion resistance, high strength, non-deformation, high temperature resistance, long service life, environmental protection and beautiful appearance.

[0035] like Figure 1 As shown, in an optional embodiment of the present invention, the at least one bolt 4 is three bolts.

[0036] In this embodiment, Figure 1As shown, preferably, three bolts 4 are used to fix the adapter 1 to the curtain wall keel column 2, so that the connection between the adapter 1 and the curtain wall keel column 2 is more secure.

[0037] In an optional embodiment of the present invention, the adapter 1 is fixedly connected to the curtain wall keel column 2 by at least one self-tapping screw.

[0039] During installation, at both ends of the beam profile close to the glass curtain wall, such as Figure 3 As shown, a 50mmx23mm milling notch needs to be processed; Figure 4 As shown, use bolts 4 to fix the adapter 1 on the curtain wall keel column 2; Figure 5 As shown, then align the milled notch on the beam 3 with the adapter 1 and apply a thrust to clamp the beam 3 on the adapter 1. The first and second clamping blocks at the end of the adapter 1 are firmly clamped with the protrusion 6; Figure 6 As shown, the machine nails 5 are then used to nail the side walls of the beams 3 through the cardboard on the adapter 1 to complete the installation of the curtain wall frame closed cavity beam connection device, as shown in FIG. Figure 7 shown.

[0040] The solution of the present invention realizes the appearance of a fully closed-cavity beam building, with better architectural effects and no unnecessary splicing gaps; it can enable the beam to bear a larger load and the weight of the glass panel without torsional deformation of the beam; it can meet the requirements of local construction standards that frames in areas over 50 meters cannot use pin or spring pin connections; it can realize disorderly construction and installation of beams and columns; it adopts a combination of bolts and screws for connection, and at the same time, the beams are connected with screws and T-shaped adapters, which can play a pulling effect, making the beams not easy to fall off. In this way, the ultimate bearing capacity of the connection between the beams and columns is higher, the safety is higher, and larger glass panels can be supported.
