Description

Technical Field

[0001] This invention belongs to the field of building curtain wall design and construction installation technology, and particularly relates to an installation method for a wide wing-shaped glass curtain wall system. Background Technology

[0002] As the most common form of curtain wall, glass curtain walls are widely used in high-standard office buildings and other structures due to their aesthetic appeal and durability. However, with the increasing diversification of architectural forms and rising standards of living, more and more office buildings are incorporating balconies on secondary facades to provide users with spaces for relaxation and socializing during their busy workdays, while also creating rich shadows on the facade. However, balconies often have an inter-facade relationship with the building facade, and considering their shape or load-bearing capacity, traditional glass curtain wall designs are sometimes unsuitable. This can lead to difficulties in connecting and securing the curtain wall at the balcony, compromising the architectural style and making the balcony appear abrupt on the main facade. Therefore, this invention designs a method for installing a wide, wing-shaped glass curtain wall system that extends outwards from the edges of the main facade glass curtain wall without requiring connection or fixation to balconies on secondary facades. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an installation method for a wide, wing-shaped glass curtain wall system. This system extends outward from the main facade glass curtain wall, effectively shielding components protruding from the building on the secondary facade. Furthermore, it eliminates the need for connection and fixation to these components, thereby achieving an architectural style with an all-glass curtain wall design in the visual effect of the main facade while ensuring functional requirements.

[0004] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0005] An installation method for a wide, wing-shaped glass curtain wall system includes the following steps: Step 1: Installation of the main curtain wall frame; The main curtain wall frame consists of columns and beams. One end of the beam is welded to the column, and the other end is connected by a steel insert. Then, the overall strength of the frame in the outermost span of the main curtain wall is reinforced. Step 2: Installation of the flying wing curtain wall frame; First, the horizontal main keel located between the layers of the flying wing curtain wall and at the bottom is installed along the entire length of the two spans of the flying wing curtain wall, with one end welded to the bevel of the main curtain wall column and the other end cantilevered; then, the vertical secondary keel of the flying wing curtain wall is installed, with the bottom of the vertical secondary keel connected to the horizontal main keel by steel inserts and the top welded to the bevel of the horizontal main keel, and the vertical secondary keel in the uppermost area is only fixed to the bottom of the horizontal main keel by welding to the bevel of the horizontal main keel; then, the remaining auxiliary frames are installed on the vertical secondary keel; Step 3: Surface layer installation.

[0006] Furthermore, in step 1, the columns of the main curtain wall are made of 120×70×5mm fluorocarbon-coated right-angled steel square tubes, and the beams of the main curtain wall are made of 70×70×4mm fluorocarbon-coated right-angled steel square tubes.

[0007] Furthermore, in step 1, the specific method for strengthening the overall strength of the outermost span of the main curtain wall frame is as follows: The two columns of this span are made of 200×80×6mm fluorocarbon-coated right-angled steel square tubes, and the crossbeams of this span are made of 200×80×6mm fluorocarbon-coated right-angled steel square tubes, 70×70×4mm fluorocarbon-coated right-angled steel square tubes, 160×80×6mm fluorocarbon-coated right-angled steel square tubes and 200×200×8mm fluorocarbon-coated right-angled steel square tubes. The specific locations of the beams of different specifications are as follows: 160×80×6mm fluorocarbon-coated right-angle steel square tubes are used for the top horizontal connection of the main curtain wall; 200×80×6mm and 200×200×8mm fluorocarbon-coated right-angle steel square tubes are used for the bottom horizontal connection of the upper glass and the top horizontal connection of the lower glass in the inter-layer area; 70×70×4mm fluorocarbon-coated right-angle steel square tubes are used for the horizontal connection of the glass partitions in the non-inter-layer area; except for the 70×70×4mm fluorocarbon-coated right-angle steel square tube, which is still connected to the column by a fillet weld at one end and a steel insert at the other end, the beams of other specifications are connected to the column by bevel welding at both ends.

[0008] Furthermore, in step 2, the installation method of the wing-shaped curtain wall auxiliary frame is as follows: The horizontal keel used for glass partitioning in the middle of the floor is made of 70×70×4mm fluorocarbon-coated right-angled steel square tube, which is connected to the vertical secondary keel at one end by a steel insert and the other end by fillet weld; the horizontal keel used for partitioning aluminum panels and glass between floors is made of 200×80×6mm fluorocarbon-coated right-angled steel square tube, which is connected to the vertical secondary keel at both ends by bevel weld; the horizontal keel used for the topmost capping aluminum panel is made of 160×80×6mm fluorocarbon-coated right-angled steel square tube, which is connected to the vertical secondary keel at both ends by bevel weld.

[0009] Furthermore, the specific method for installing the surface layer in step 3 is as follows: There is a distance between the inner side of the flying wing curtain wall and the balcony on the secondary facade of the building. Aluminum panels are used to seal the exposed main structure, while the inner side is filled with thermal insulation rock wool. Then, the flying wing curtain wall frame on the outside is wrapped with shaped aluminum panels. Finally, the adhesive is injected.

[0010] The present invention has the following beneficial effects: This invention involves installing a wide, wing-shaped glass curtain wall system after the main facade glass curtain wall framework is completed. Unlike conventional component-based glass curtain wall systems, this system uses horizontally cantilevered steel main keels that do not require connection to the main structure. Vertical secondary keels are installed on the horizontal main keels to form a complete wing-shaped curtain wall main framework system. After the main framework is completed, the auxiliary frameworks are installed, including glass dividing beams, inter-layer aluminum panel frameworks, and roof coping aluminum panel frameworks. Finally, the surface materials such as glass, aluminum panels, and profile moldings are installed. This invention is suitable for situations where there are auxiliary structures on the secondary facade of a building, the curtain wall cannot be connected and fixed, or to ensure the visibility of the main facade. The overall visual effect is aesthetically pleasing and elegant, while maintaining architectural style consistency, and can serve as a reference for similar projects. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0013] The installation method of the wide wing-shaped glass curtain wall system of the present invention includes the following process: Step 1: Installation of the main curtain wall frame; like Figure 1 As shown, the main keel (column) of the main curtain wall is made of 120×70×5mm fluorocarbon-coated right-angle steel square tube G2, and the secondary keel (beam) of the main curtain wall is made of 70×70×4mm fluorocarbon-coated right-angle steel square tube G3; the beam and column are connected by fillet welding at one end and steel insert at the other end.

[0014] To ensure the overall structural safety of the flying wing curtain wall, the overall strength of the outermost span of the main curtain wall frame needs to be reinforced, as detailed below: The two columns of this span are made of 200×80×6mm fluorocarbon-coated right-angled square steel tubes G1. The crossbeams of this span are made of 200×80×6mm fluorocarbon-coated right-angled square steel tubes G1, 70×70×4mm fluorocarbon-coated right-angled square steel tubes G3, 160×80×6mm fluorocarbon-coated right-angled square steel tubes G4, and 200×200×8mm fluorocarbon-coated right-angled square steel tubes G5. The specific arrangement of the crossbeams in this span is as follows: Figure 1 As shown, the 160×80×6mm fluorocarbon-coated right-angle steel square tube G4 is used for the top horizontal connection of the main curtain wall; the 200×80×6mm fluorocarbon-coated right-angle steel square tube G1 and the 200×200×8mm fluorocarbon-coated right-angle steel square tube G5 are used for the bottom horizontal connection of the upper glass and the top horizontal connection of the lower glass in the interlayer area; and the 70×70×4mm fluorocarbon-coated right-angle steel square tube G3 is used for the horizontal connection of the glass partitions in the non-interlayer area. In addition to the 70×70×4mm fluorocarbon-coated right-angle steel square tube G3 still using the connection method of one end fillet weld and the other end steel insert to the column, the other specifications of the horizontal beams are all connected to the column by the method of bevel welding at both ends.

[0015] Step 2: Installation of the flying wing curtain wall frame; like Figure 1 As shown, the horizontal main keel of the flying wing curtain wall is first clarified to be a 200×200×8mm fluorocarbon sprayed right-angle steel square tube G5, which is located in the inter-floor part and at the bottom. It is installed along the entire length of the two spans of the flying wing curtain wall. One end of it is firmly welded to the 200×80×6mm fluorocarbon sprayed right-angle steel square tube G1 column of the main curtain wall with a bevel weld, and the other end is cantilevered.

[0016] After the horizontal main keel is installed, the vertical secondary keel of the flying wing curtain wall is installed. The vertical secondary keel uses 200×80×6mm fluorocarbon sprayed right-angle steel square tube G1. Its bottom is connected to the horizontal main keel through steel insert, and its top is welded to the horizontal main keel with bevel welding. The vertical secondary keel in the uppermost area is mainly used for the roof coping aluminum plate. It is relatively short, so only the bottom is fixed to the horizontal main keel with bevel welding.

[0017] After the main and secondary keels of the flying wing curtain wall are installed, the auxiliary frame can be installed: the horizontal keel used for glass partitioning in the middle area of ​​the floor uses 70×70×4mm fluorocarbon-coated right-angle steel square tube G3, which is connected to the vertical secondary keel at one end through a steel insert and the other end is welded; the horizontal keel used for aluminum panels and glass partitioning between floors uses 200×80×6mm fluorocarbon-coated right-angle steel square tube G1, which is connected to the vertical secondary keel at both ends by bevel welding; the horizontal keel used for the topmost coping aluminum panel uses 160×80×6mm fluorocarbon-coated right-angle steel square tube G4, which is connected to the vertical secondary keel at both ends by bevel welding.

[0018] Step 3: Surface layer installation; The surface treatment of the wing-shaped curtain wall, such as glass and aluminum panels, is the same as that of conventional types and will not be repeated here. Since there is a certain distance between the inner side of the wing-shaped curtain wall and the balcony on the secondary facade of the building, aluminum panels are used to seal the exposed main structure, while the inner side is filled with thermal insulation rock wool. In addition, since the frame of the wing-shaped curtain wall is outdoors, in order to ensure durability and aesthetic requirements, the frame is wrapped with shaped aluminum panels; finally, the grouting work can be carried out.

[0019] The embodiments described above are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essence of the present invention shall fall within the protection scope of the present invention.
