Description

Technical Field

[0001] The utility model belongs to the technical field of exterior decoration of building curtain walls, and particularly relates to an anti-slip beam-column bidirectional sliding connection node and a curtain wall. Background Technique

[0002] Generally, there are two forms of connecting the cross beams of glass curtain walls, namely angle code connection and pin connection. In recent years, pin connection has been widely used because of its advantages such as simple processing, easy control of construction accuracy, and fast construction speed. However, for the traditional bidirectional sliding connection of the cross beam and column (referred to as "beam-column") with pins, there is no horizontal constraint, which is not conducive to the overall stiffness of the curtain wall system.

[0003] According to the relevant technical specifications of building curtain wall projects: for curtain walls with a height exceeding 50m, the beam-column connection form in which both ends of the cross beam can slide should not be adopted, and the pin connection method of bidirectional sliding connection of beam-column cannot be used as the lateral restraint of the column. Moreover, when the curtain wall column bears the radial force around the column, there is also a risk of the cross beam sliding and the pin coming out of the installation hole in the traditional pin connection.

[0004] Therefore, it is necessary to propose a new anti-slip connection measure for the cross beam of the curtain wall to overcome the defects of poor overall stiffness of the bidirectional sliding connection and the risk of sliding out. Content of the Utility Model

[0005] To solve the above problems, the utility model proposes an anti-slip beam-column bidirectional sliding connection node, which adds an anti-slip connecting piece on the basis of the original bidirectional sliding pin connection. Thus, it can not only improve the overall stiffness of the curtain wall system, but also avoid the risk of the cross beam sliding horizontally and coming out of the installation hole when the column is subjected to radial force. Further, the utility model also discloses a curtain wall with the above anti-slip beam-column bidirectional sliding connection node.

[0006] The utility model adopts the following technical solutions to achieve the above invention purposes:

[0007] An anti-slip beam-column bidirectional sliding connection node, which comprises an aluminum alloy cross beam, an aluminum alloy column, a cross beam connection assembly, and an anti-slip connection member. Among them, the anti-slip connection member is further divided into a first anti-slip connection member and a second anti-slip connection member; the aluminum alloy cross beam has a first hollow cavity and a first notch arranged at the front end of the first hollow cavity; the aluminum alloy column has a second hollow cavity and a second notch arranged at the front end of the second hollow cavity, and both side walls of the second notch are respectively provided with a vertically arranged slot; the height of the anti-slip connection member matches the height of the first notch at the front end of the aluminum alloy cross beam, and has a first connection surface and a second connection surface. Among them, the first connection surface of the first anti-slip connection member has a horizontally arranged oblong hole; during installation and use, the aluminum alloy cross beam is fixed on both sides of the aluminum alloy column through the cross beam connection assembly; the first connection surface of the first anti-slip connection member is attached to the inner wall of the first notch of the aluminum alloy cross beam, and is fixedly connected to the inner wall of the first notch through a screw arranged at the oblong hole; the second connection surface of the second anti-slip connection member is inserted into the slot of the aluminum alloy column and is attached to the inner wall of the second notch of the aluminum alloy column, and is fixedly connected to the inner wall of the second notch through a screw.

[0008] As an alternative, the anti-slip connection member further includes a limiting beam arranged at the boundary between the first connection surface and the second connection surface.

[0009] As an alternative, the screw is a pan head screw.

[0010] As an alternative, the cross beam connection assembly includes an aluminum alloy core insert and a stainless steel pin; the outer contour of the aluminum alloy core insert matches the first hollow cavity of the aluminum alloy cross beam; the aluminum alloy core insert is fixedly connected to the aluminum alloy cross beam through a screw, and is provided with a pin line for installing the stainless steel pin; the cross beam connection assembly is fixedly connected to the aluminum alloy column through the stainless steel pin.

[0011] As an alternative, the aluminum alloy core insert also has a hollow cavity, and the cross-sectional shape of its cavity is basically the same as that of the cavity of the aluminum alloy cross beam.

[0012] As an alternative, there are three pin lines, which are two arranged at the front end of the aluminum alloy core insert and one arranged at the rear end of the aluminum alloy core insert respectively.

[0013] Furthermore, the present invention also discloses a curtain wall, which has a plurality of the anti-slip beam-column bidirectional sliding connection nodes described in any one of the above.

[0014] The utility model adopts the above technical solutions and has the following beneficial effects:

[0015] Based on the original two-way sliding connection between beams and columns, by adding anti-slip connection components, a structure is achieved where one end of the connection between the cross beam and the column is fixed, and the other end is connected through a long circular hole for sliding. This not only improves the overall stability of the curtain wall system but also enhances the anti-torsion ability of the cross beam. Brief Description of the Drawings

Detailed Embodiments

[0023] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with specific embodiments and the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] In the description of the present utility model, if terms indicating orientation or positional relationship such as "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "top", "bottom", etc. appear, they are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, that is, they may include other units not clearly listed or inherent to these products or devices.

[0025] As shown in combination with Figures 1 to 6 the accompanying drawings, an anti-slip beam-column bidirectional sliding connection node disclosed in an embodiment of the present utility model mainly includes components such as a crossbeam connection assembly 100, an aluminum alloy crossbeam 200, an aluminum alloy column 300, an anti-slip connection member 400, and screws.

[0026] Both the aluminum alloy crossbeam 200 and the aluminum alloy column 300 adopt a traditional structure and have a hollow cavity. The front end of the aluminum alloy crossbeam 200 has a notch 201, and the front end of the aluminum alloy column 300 has a notch 301. In addition, both side walls of the notch 301 at the front end of the aluminum alloy column 300 have a vertical slot 302 for inserting the anti-slip connection member 400.

[0027] The crossbeam connection assembly 100 is mainly composed of an aluminum alloy core 101 and a stainless steel pin 102. As Figure 5 shown in the accompanying drawings, the outer contour of the aluminum alloy core 101 matches the cavity of the aluminum alloy crossbeam 200. The aluminum alloy core 101 also has a hollow cavity, and the cross-sectional shape of the cavity is basically the same as that of the cavity of the aluminum alloy crossbeam 200. There are three nail lines 1011 in the cavity of the aluminum alloy core 101, which are respectively arranged on the front and rear inner walls of the cavity for fixing the stainless steel pin 102.

[0028] As Figure 6As shown in the figure, the height of the anti-slip connector 400 matches the height of the notch 201 at the front end of the aluminum alloy cross beam 200. The anti-slip connector 400 is fixed between the cross beam and the column by screws. Specifically, during installation, its first connection surface 401 fits against the rear wall of the notch 201 of the aluminum alloy cross beam 200, and the second connection surface 402 is inserted into the slot 302 of the aluminum alloy column 300 and fits against the rear wall of the notch 301 of the aluminum alloy column 300. Then, the first connection surface 401 of the anti-slip connector 400 and the aluminum alloy cross beam 200 are connected and fixed by pan head screws 500 respectively, and the second connection surface 402 and the aluminum alloy column 300 are connected and fixed. Further, a limiting beam 403 is provided at the boundary between the first connection surface 401 and the second connection surface 402 for positioning when inserting the aluminum alloy column 300. In addition, the anti-slip connector 400 can be specifically divided into two categories. One category has a transverse long circular hole 404 opened on the first connection surface 401, and the other category does not need to open a long circular hole.

[0029] The installation method of the anti-slip beam-column bidirectional sliding connection node disclosed in the embodiment is as follows:

[0030] Tap the thread inside the nail line of the aluminum alloy insert core 101 in the factory, fix the threaded stainless steel pin 102 inside the nail line 1011 of the aluminum alloy insert core 101, and lock the aluminum alloy insert core 101 to the aluminum alloy cross beam 200 through countersunk head screws, thus completing the processing of the cross beam connection assembly 100. At the same time, process the pin installation holes on the aluminum alloy column 300 in the factory.

[0031] Insert the processed cross beam connection assembly 100 into the cavity of the aluminum alloy cross beam 200, and fix the aluminum alloy cross beam 200 with the cross beam connection assembly 100 to the aluminum alloy column 300 through the stainless steel pin 102, thus completing the installation of the aluminum alloy cross beam 200.

[0032] Process the long circular hole 404 on the anti-slip connector 400 on the right side of the aluminum alloy column 300; fix one anti-slip connector 400 between the left aluminum alloy cross beam 200 and the aluminum alloy column 300 through pan head screws 500, and fix the other anti-slip connector 400 with the long circular hole 404 opened between the right aluminum alloy cross beam 200 and the aluminum alloy column 300 through pan head screws 500 to complete the installation of the curtain wall anti-slip connector 400. Among them, the reason for opening the transverse long circular hole 404 on the right anti-slip connector 400 is mainly to release the temperature difference deformation of the aluminum alloy cross beam 200, changing the original beam-column bidirectional sliding structure into a unidirectional sliding.

[0033] Further, the embodiment of the present invention also discloses a curtain wall having the above anti-slip beam-column bidirectional sliding connection node.

[0034] Finally, it should be noted that the above description is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, making equivalent substitutions or changes, should be covered by the protection scope of the present utility model.
