Description

Technical Field

[0001] This utility model relates to a unitized curtain wall structure based on a single column, belonging to the field of unitized curtain wall technology. Background Technology

[0002] Unitized curtain walls are the mainstream enclosure structure for modern building facades. They are constructed by prefabricating unit panels in factories and assembling them on-site. They are characterized by high construction efficiency, excellent sealing performance, and strong overall appearance. They are widely used in large projects such as high-rise buildings and commercial complexes. However, existing unitized curtain wall structures have some shortcomings. On the one hand, they often use double-column or bolted connection designs, which can easily lead to positioning deviations during installation. After long-term use, the overall stability of the curtain wall may be affected by loosening of the connectors. On the other hand, the compatibility between the column and the base materials is poor. If different materials are used, additional matching parts often need to be processed, which directly reduces production and installation efficiency. Utility Model Content

[0005] Preferably, two heat insulation strips are provided between the aluminum alloy isolation component and the aluminum alloy base.

[0006] Preferably, the aluminum alloy spacer is U-shaped with the opening facing outwards, and foam rods are filled between the two sides of the aluminum alloy spacer and the ends of the adjacent glass panel, with sealant applied around the foam rods.

[0007] Preferably, the aluminum alloy pressure plate is in the shape of a "Z" and the middle part of the aluminum alloy pressure plate is engaged in the U-shaped groove of the aluminum alloy separator.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] As attached Figure 1-3 As shown, the unit curtain wall structure based on a single column of this utility model includes a steel column 1, an aluminum alloy base 2, a glass panel 3, an aluminum alloy separator 4, and an aluminum alloy pressure plate 5.

[0020] In this embodiment, the aluminum alloy base 2 is made of aluminum alloy profile. The rear two sides of the aluminum alloy base 2 are integrally formed with limiting plates 21. A receiving groove is formed between the limiting plates 21 on both sides of the aluminum alloy base 2. The steel column 1 is installed and fixed in the receiving groove without additional positioning adjustment. This avoids the positioning deviation problem that is easy to occur in the existing double column or bolt connection design. At the same time, the single column structure simplifies the overall stress system and improves the stability of the curtain wall against wind load and earthquake. Self-tapping screws 11 are provided on the limiting plates 21 on the front side and both sides of the aluminum alloy base 2. The steel column 1 and the aluminum alloy base 2 are connected and fixed by the self-tapping screws 11, forming a stable connection between the two.

[0021] The ends of adjacent glass panels 3 are fixed to the front sides of the aluminum alloy base 2. In this embodiment, the glass panels 3 are bonded to the aluminum alloy base 2 with structural adhesive and double-sided adhesive. The aluminum alloy separator 4 is installed in the middle of the front end of the aluminum alloy base 2 and separates the adjacent glass panels 3 to prevent them from being squeezed and broken when the glass expands and contracts due to heat.

[0022] Specifically, two thermal insulation strips 6 are provided between the aluminum alloy isolation member 4 and the aluminum alloy base 2. In this embodiment, the aluminum alloy isolation member 4 is U-shaped and the opening faces outward. The aluminum alloy isolation member 4 is connected to the aluminum alloy base 2 by the two thermal insulation strips 6, and a thermal insulation cavity 7 is formed between the two thermal insulation strips 6. By utilizing the low thermal conductivity of the thermal insulation strips 6 and the air thermal insulation effect of the thermal insulation cavity 7, the thermal conductivity coefficient of the curtain wall is greatly reduced, and the energy-saving effect of the building is improved.

[0023] Furthermore, foam rods 8 are filled between the two sides of the aluminum alloy separator 4 and the ends of the adjacent glass panel 3, and sealant 9 is applied around the foam rods 8. The foam rods 8 can absorb the amount of glass deformation, and the sealant 9 forms a waterproof and windproof barrier.

[0024] The middle part of the aluminum alloy pressure plate 5 is fixed to the aluminum alloy spacer 4. The two ends of the aluminum alloy pressure plate 5 press against the ends of the adjacent glass panel 3 from the outside. In this embodiment, the aluminum alloy pressure plate 5 is shaped like a "Z". The middle part of the aluminum alloy pressure plate 5 is snapped into the U-shaped groove of the aluminum alloy spacer 4. The two ends of the aluminum alloy pressure plate 5 are bonded to the adjacent glass panel 3 with silicone structural adhesive 10. This avoids the problems of easy cracking of the sealant 9 and easy loosening of the connector in traditional bolt connections. Moreover, the "Z" shaped structure not only ensures the structural strength of the pressure plate, but also simplifies the installation through the snap-fit ​​design.

[0025] As attached Figure 2As shown, an aluminum alloy cover 51 is further provided on the aluminum alloy pressure plate 5. The aluminum alloy cover 51 is attached to the aluminum alloy pressure plate 5 by a staggered hook structure. On the one hand, it covers the aluminum alloy pressure plate 5, structural adhesive and other internal components, so that the exterior facade of the curtain wall presents a flat and uniform visual effect and improves the overall appearance. On the other hand, it isolates rainwater and dust from corroding the aluminum alloy pressure plate 5 and the adhesive layer, and extends the service life of the components.

[0026] Furthermore, aluminum single panels 22 are provided on both sides of the aluminum alloy base 2. The aluminum single panels 22 are connected and fixed to the limiting plate 21 of the aluminum alloy base 2 by self-tapping screws 11. The aluminum single panels 22 are parallel to the glass panel 3. The aluminum single panels 22 can protect the sides of the base from external impact and rain erosion, and improve the durability of the structure.

[0027] In summary, this application adopts a single column to replace the traditional double column structure, which simplifies the stress system, reduces the number of connectors, avoids the positioning deviation that is prone to occur with double columns, and also reduces the risk of connectors loosening during long-term use, thereby improving the overall stability of the curtain wall against wind loads and earthquakes. The limiting plate 21 and the aluminum alloy base 2 are integrally formed to form a receiving groove that fits the steel column 1, which can accurately position the steel column 1 without additional adjustment, greatly improving production and installation efficiency, while ensuring the connection is firm.

[0028] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
