Description

Technical Field

[0001] The invention belongs to the technical field of building engineering glass curtain walls, and particularly relates to an assembly structure of a lightning protection glass curtain wall for high-rise buildings. Background Technique

[0002] A glass curtain wall refers to an architectural exterior enclosure structure or decorative structure in which the supporting structure system can have a certain displacement ability relative to the main structure and does not share the actions received by the main structure. A glass curtain wall is an aesthetically novel method for building wall decoration and is a remarkable feature of the modernist high-rise building era. A framed supported glass curtain wall is a glass curtain wall in which the glass panels are supported by a metal frame around the perimeter.

[0003] Compared with the traditional masonry structure exterior wall, the glass curtain wall has the advantages of being light in shape, strong in architectural expressiveness, and fast in construction, and is becoming more and more popular in the application of building exterior wall decoration. However, the popularization and application of the glass curtain wall have also had a certain impact on the safe use of the building structure in lightning weather. The self-lightning protection device of the main body of the building structure cannot directly play a lightning protection role due to the shielding effect of the glass curtain wall. A strong lightning current side-strikes the curtain wall, and the induced charges generated by the metal keel of the curtain wall cannot be discharged. When the people indoors touch the indoor metal conductor, a potential difference is generated on the body and they are instantly electrocuted. The safety problem in lightning weather has largely restricted the popularization and application of the glass curtain wall in building structure engineering. Summary of the Invention

[0004] To solve the above technical problems, the invention provides an assembly structure of a lightning protection glass curtain wall for high-rise buildings.

[0005] The invention is achieved through the following technical solutions.

[0006] The invention provides an assembly structure of a lightning protection glass curtain wall for high-rise buildings, which includes a plurality of columns arranged vertically and fixed on the outer facade of the building, a plurality of crossbeams arranged horizontally and fixed between two adjacent columns, a plurality of embedded parts embedded in the building, and a plurality of "U"-shaped clamping hoops. The clamping hoops are clamped on the columns or crossbeams, and their left and right sides are respectively fixed to the outer facade of the building, the corresponding columns or crossbeams by screws. A bowl-shaped sink is also provided on the clamping hoops. The end of the embedded part sequentially penetrates through the column or crossbeam, the clamping hoop and is screwed to a locking nut, and the locking nut is accommodated in the corresponding bowl-shaped sink. The surface of the clamping hoop is used for installing the glass curtain wall.

[0007] When the heights of the columns in the same vertical direction are insufficient, the upper and lower columns are connected by a movable core.

[0008] The length of the movable core is not less than 280 mm, and the connection between the movable core and the column is sealed and filled with silicone weather-resistant sealant.

[0009] The lightning protection glass curtain wall assembly structure of the high-rise building further includes a copper stranded wire, and both ends of the copper stranded wire are respectively clamped between the locking nut and the bowl-shaped sink, and the middle part of the copper stranded wire is accommodated between the cover hoop and the column or between the cover hoop and the cross beam, so that two adjacent embedded parts along the vertical direction or two adjacent embedded parts along the horizontal direction are connected together by the corresponding copper stranded wire.

[0010] The nominal outer diameter of the copper stranded wire is not less than φ1.5mm.

[0011] The embedded part is made of a circular steel pipe.

[0012] The outer diameter of the circular steel pipe is not less than φ12mm.

[0013] A gap of 1.5 to 2 mm is reserved at the intersection of the cross beam and the column, and it is sealed and filled with silicone weatherproof sealant.

[0014] The cover hoop is formed by bending a carbon structural steel plate with a thickness of not less than 1.2 mm.

[0015] The surface of the embedded part or the cover hoop is coated with inorganic zinc-rich anti-rust paint, and the thickness of the inorganic zinc-rich anti-rust paint is not less than 100 microns.

[0016] The beneficial effects of the present invention are as follows: adopting the technical solution of the present invention, on the one hand, the column and the cross beam form a support framework to support the glass curtain wall. The column and the cross beam are both steel structural members and are connected to the embedded part as a whole, so that the glass curtain wall is connected to the main structure of the building as a whole, and the connection is more compact and reliable. On the other hand, two adjacent embedded parts are connected together by a copper stranded wire, forming a charge transfer network between the glass curtain wall and the main structure of the building. When lightning strikes, the charge transfer network can transfer the charge generated by the lightning to the main structure of the building and then connect it to the ground, thereby improving the lightning protection ability of the glass curtain wall. In addition, a plurality of silicone weatherproof sealants are provided at the connection of the column and the cross beam, effectively improving the durability and waterproofness of the glass curtain wall. In addition, the copper stranded wire is hidden between the cover hoop and the column or between the cover hoop and the cross beam, and is not exposed to the outside, improving the overall appearance of the building and the glass curtain wall. The glass curtain wall assembly structure provided by the present invention has a simple construction process. The embedded part is arranged at the side beam of the floor slab, and the embedded points can be easily obtained on the main structure. The construction machinery and equipment required in the construction process are simple and the construction progress is relatively fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the present invention will be further described below, but the scope of protection is not limited thereto.

[0021] As Figure 1 、 Figure 2 As shown in the figure, the present invention provides a lightning protection glass curtain wall assembly structure for high-rise buildings, including a plurality of vertical columns 1 arranged along the vertical direction and fixed on the outer facade of the building 4, a plurality of cross beams 2 arranged along the horizontal direction and fixed between adjacent two vertical columns 1, a plurality of embedded parts 5 embedded in the building 4, and a plurality of "U"-shaped cover hoops 3. The cover hoops 3 are clamped on the vertical columns 1 or cross beams 2, and their left and right sides are respectively fixed to the outer facade of the building 4 and the corresponding vertical columns 1 or cross beams 2 by screws. A bowl-shaped sunk groove is also provided on the cover hoops 3. The end of the embedded part 5 sequentially penetrates through the vertical column 1 or cross beam 2 and the cover hoop 3 and is screwed with the locking nut 6, and the locking nut 6 is accommodated in the corresponding bowl-shaped sunk groove. The surface of the cover hoop 3 is used for installing the glass curtain wall 7.

[0022] Furthermore, when the heights of the vertical columns 1 located in the same vertical direction are insufficient, the upper and lower two vertical columns 1 are connected by an active core. The length of the active core is not less than 280 mm, and the connection between the active core and the vertical column 1 is sealed and filled with silicone weatherproof sealant.

[0023] In addition, the lightning protection glass curtain wall assembly structure for high-rise buildings further includes a copper stranded wire 8. The two ends of the copper stranded wire 8 are respectively clamped between the locking nut 6 and the bowl-shaped sunk groove, and the middle part of the copper stranded wire 8 is accommodated between the cover hoop 3 and the vertical column 1 or between the cover hoop 3 and the cross beam 2, so that two adjacent embedded parts 5 along the vertical direction or two adjacent embedded parts 5 along the horizontal direction are connected together by the corresponding copper stranded wire 8. The nominal outer diameter of the copper stranded wire 8 is not less than φ1.5 mm. The embedded part 5 is made of a circular steel pipe. The outer diameter of the circular steel pipe is not less than φ12 mm. A gap of 1.5 to 2 mm is reserved at the intersection of the cross beam 2 and the vertical column 1, and it is sealed and filled with silicone weatherproof sealant. The cover hoop 3 is formed by bending a carbon structural steel plate with a thickness not less than 1.2 mm. The surface of the embedded part 5 or the cover hoop 3 is coated with inorganic zinc-rich anti-rust paint, and the thickness of the inorganic zinc-rich anti-rust paint is not less than 100 microns.

[0024] Adopting the technical solution of the present invention, on the one hand, the columns and crossbeams form a support framework to support the glass curtain wall. Both the columns and crossbeams are steel structural members and are connected to the embedded parts as a whole, so that the glass curtain wall is connected to the main structure of the building as a whole, and the connection is more compact and reliable. On the other hand, adjacent two embedded parts are connected together by copper stranded wires to form a charge leakage network between the glass curtain wall and the main structure of the building. When lightning strikes, the charge leakage network can transfer the charges generated under lightning to the main structure of the building and then connect to the ground, thereby enhancing the lightning protection ability of the glass curtain wall. In addition, a plurality of silicone weatherproof sealants are provided at the joints of the columns and crossbeams, effectively improving the durability and waterproofness of the glass curtain wall. Moreover, the copper stranded wires are hidden between the cover hoop and the column or between the cover hoop and the crossbeam without being exposed outside, improving the overall appearance of the building and the glass curtain wall. The construction process of the glass curtain wall assembly structure provided by the present invention is simple. The embedded parts are arranged at the side beams of the floor slab, and the embedded points can be easily set on the main structure. The construction mechanical equipment required in the construction process is simple and the construction progress is relatively fast.
