Description

Technical Field

[0001] The invention relates to a sectional folded line cantilevered assembled curtain wall system, belonging to the technical field of building curtain walls. Background Art

[0002] Buildings that want to achieve unique facade effects typically utilize framed curtain walls. Each component of a framed curtain wall system must be factory-fabricated and then transported to the site for installation. Component lengths and hole placements must be tailored to the complex on-site structure. While this ensures the overall quality and accuracy of the curtain wall, it is unsuitable for the diverse structural forms of modern buildings due to constraints such as construction sequence and on-site coordination.

[0003] As a new development trend in the building decoration industry, prefabricated curtain walls combine and install the skeleton, profile components, and surface materials in the factory, then transport them to the site for orderly hoisting. Compared with conventional frame curtain wall systems, they are more efficient to install and more suitable for curtain wall forms with variable structures. Currently, most prefabricated curtain wall technologies are only used in projects with a single structure or regular changes. When faced with variable structures and limited installation space, conventional prefabricated curtain walls cannot fully demonstrate their advantages of high quality, high efficiency, energy saving and environmental protection. While ensuring the high quality and efficiency of the project, how to adopt prefabricated curtain walls in the case of variable inter-story fold line cantilever structures is a question worthy of in-depth research.

[0027] As attached Figure 1-3 As shown, the present invention describes a lattice-type folded-line cantilevered assembled curtain wall system, which includes a folded-line curtain wall body, an upper crossbeam 1, a lower crossbeam 2, and a plurality of adapter components. The upper crossbeam 1 and the lower crossbeam 2 are respectively installed and fixed at the upper and lower ends of the folded-line curtain wall body; each folded-line curtain wall body is assembled horizontally from a plurality of lattice units to form an integral structure.

[0028] Each grid unit includes a special-shaped steel frame, a glass panel 3, an inclined aluminum plate 4 and a vertical aluminum plate 5; the special-shaped steel frame includes a first rectangular frame 6, a triangular frame 7 and a second rectangular frame 8 arranged in sequence from top to bottom, the upper crossbeam 1 is fixed to the top of the first rectangular frame 6 by M10X35mm stainless steel bolts, and the lower crossbeam 2 is fixed to the bottom of the second rectangular frame 8 by M10X35mm stainless steel bolts, forming the keel support structure of the grid unit.

[0029] In this embodiment, the first rectangular frame 6 is welded by two 100*63mm angle steels arranged in parallel up and down and an 80*50mm steel square tube located between the two angle steels, and the second rectangular frame 8 is welded by two 100*100mm steel square tubes arranged in parallel up and down and a 100*50 steel square tube located between the two steel square tubes.

[0030] The glass panel 3 is vertically mounted on the outside of the first rectangular frame 6. Specifically, a U-shaped connector 9 is fixedly provided on the first rectangular frame 6 at the lower end of the glass panel 3. The lower end of the glass panel 3 is inserted into the U-shaped connector 9, and the upper end of the glass panel 3 is fixed to the upper crossbeam 1 by structural adhesive. In this embodiment, the glass panel 3 adopts hollow glass with a LOW-E surface treatment and an inert gas filled in the middle to reduce heat radiation and improve the energy-saving performance of the glass panel 3.

[0031] The inclined aluminum plate 4 is installed obliquely on the top surface of the triangular frame 7. Specifically, the upper end of the inclined aluminum plate 4 has a bending structure 41, which is inserted into the edge of the U-shaped connector 9. The lower end of the inclined aluminum plate 4 can be fixed to the second rectangular frame 8 by self-tapping screws, and shares a U-shaped connector 9 with the glass panel 3, which limits and fixes the inclined aluminum plate 4 and the glass panel 3, and is also convenient for disassembly and replacement.

[0032] In this embodiment, flexible pads 10 are provided at the contact positions between the glass panel 3 and the U-shaped connector 9 and at the contact positions between the glass panel 3 and the bending structure 41 of the inclined aluminum plate 4. The flexible pads 10 can be flexible pads 10 to buffer the contact stress between the glass panel 3 and the metal frame.

After rainwater falls on it, it can be immediately discharged to the outside to prevent rainwater from gathering, realizing the design concept of combining "prevention" and "drainage" of the system. A decorative line 11 is provided between the inclined aluminum plate 4 and the vertical aluminum plate 5. The rear end of the decorative line 11 is fixed to the second rectangular frame 8 by self-tapping screws to ensure the appearance effect.

[0035] Furthermore, foam rods 12 are provided between the decorative lines 11 and the inclined aluminum plates 4 and the vertical aluminum plates 5 to ensure the sound insulation effect and further improve the sealing performance.

One end of the horizontal steel tube 71 is fixed to the bottom of the first rectangular frame 6 by welding, and the top of the horizontal steel tube 71 is fixed to the second rectangular frame 8 by welding. The length of the horizontal steel tube 71 increases from one side of the triangular frame 7 to the other side, forming a width gradient structure to meet the requirements of different entry and exit positions of the discounted curtain wall; one end of the inclined angle steel 72 is fixed to the side of the horizontal steel tube 71 close to the second rectangular frame 8 by welding, and the other side of the inclined angle steel 72 is connected and fixed to the first On the outside of a rectangular frame 6, and cooperating with the lower end of the glass panel 3, the connection height of the inclined angle steel 72 and the second rectangular frame 8 increases successively from one side of the triangular frame 7 to the other side, forming a height gradient structure to meet the requirements of different facade effects of the discounted curtain wall; it should be noted that the increasing direction of the length of the horizontal steel tube 71 is consistent with the increasing direction of the height of the inclined angle steel 72, that is, as the length of the horizontal steel tube 71 increases, the height of the inclined angle steel 72 will also increase, and conversely, as the length of the horizontal steel tube 71 decreases, the height of the inclined angle steel 72 will also decrease.

[0037] As attached Figure 5 As shown, in this embodiment, the broken line curtain wall is composed of three grid units. Of course, in actual operation, it can also be divided into 2 or 4 grid units, depending on actual requirements. During processing, a horizontal operating table that can fix the position of the rod and apply a certain restraining force is built in the workshop. After adjusting the size, the rod is welded. After the welding operation is completed and the stress is fully released, the deformation of the steel frame is measured in time, and the deformation is eliminated by hammering and vibration, thereby reducing welding errors and improving the welding quality and accuracy of the special-shaped steel frame. Then, the three parts are welded into a whole according to the model annotation drawing.
