Description

Technical Field

[0001] This application relates to the field of super-large glass curtain walls, and specifically relates to a support structure for a super-large glass curtain wall and a super-large glass curtain wall. Background Art

[0002] A glass curtain wall is a modern building peripheral structure, which consists of a glass panel and a support structure system, and is usually used for the outer walls of commercial buildings, office buildings, shopping centers and other buildings. The glass curtain wall not only provides good lighting effects, enhances the aesthetics of the building, but also integrates the indoor and outdoor environments through its transparency. In addition, modern glass curtain wall systems also have multiple functions such as heat insulation, sound insulation, and protection against wind and rain, meeting the requirements of the building for energy conservation and comfort.

[0003] In the field of glass curtain walls, a glass curtain wall with a short side length exceeding 2.4m is considered a super-large glass curtain wall. A super-large glass curtain wall is a glass curtain wall with a single-sided maximum size exceeding 2 meters or more than 3 square meters (Jia Zhaoyun, Liu Baofeng, Liang Aiju. Discussion on the Design and Construction Characteristics of Super-large Glass Curtain Walls [J]. Doors & Windows, 2014, (10): 139.). The design and construction of super-large glass curtain walls need to consider structural safety, durability and coordination with the overall architectural style, which puts forward high requirements for the frames of super-large glass curtain walls. At present, the frames of super-large glass curtain walls adopt the form of "aluminum-clad steel". The steel frames provide support and bearing capacity for the super-large glass curtain walls. The aluminum is wrapped on the outside of the steel frames, which can prevent the steel from rusting. However, when the steel and aluminum materials come into contact, electrochemical corrosion is likely to occur, and the bearing capacity of the frames of super-large glass curtain walls will be weakened accordingly, posing a safety hazard.

[0004] Therefore, how to provide a support structure for a super-large glass curtain wall that can effectively avoid electrochemical corrosion has become a technical problem to be solved in this field. Utility Model Content

[0006] According to the first aspect of this application, a support structure for a super-large glass curtain wall is proposed. The support structure for the super-large glass curtain wall includes: columns, located at the vertical parts of the support structure for the super-large glass curtain wall, providing longitudinal support; cross beams, located at the horizontal parts of the support structure for the super-large glass curtain wall, arranged on both sides of the columns, providing transverse bearing capacity; sub-frames, the sub-frames are detachably connected to the columns and / or cross beams; wherein, the columns and the cross beams form a cross structure and are detachably connected, and the material of the sub-frames is the same as that of the columns and / or cross beams.

[0011] Specifically, the pressing plate is detachably connected to the support structure of the super-large glass curtain wall.

[0012] Specifically, the super-large glass curtain wall further includes a bearing structure for the glass panel, and the bearing structure for the glass panel is arranged in the second groove of the auxiliary frame on the cross beam of the support structure of the super-large glass curtain wall for providing support to the glass panel.

Detailed implementation mode

[0028] The technical solutions of this application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In this application, an extra-large glass curtain wall with a column span of 9 meters, a cross beam span of 3.033 meters, and a single-piece glass grid of 3.033 meters × 2.700 meters is taken as an example.

[0030] The frame structure of the super-large glass curtain wall should not only have sufficient bearing capacity and support force to ensure the safety and stability of the super-large glass curtain wall, but also meet the aesthetic requirements. Usually, the frame structure of the super-large glass curtain wall adopts the form of aluminum-clad steel. The steel frame is used to provide the support force and bearing capacity, and the aluminum frame is used to provide the aesthetic property. In order to prevent the phenomenon of electrochemical corrosion caused by the contact between steel and aluminum materials, an anti-corrosion isolation gasket is usually set between the steel and aluminum. However, it is very difficult to ensure that the placement of the gasket is accurate in all construction processes, and the situation of electrochemical corrosion will still occur. Long-term use will weaken the support strength of the super-large glass curtain wall and cause potential safety hazards.

[0031] As Figures 1 - 3 shown, according to the first aspect of the present application, a support structure for a super-large glass curtain wall is proposed. The support structure of the super-large glass curtain wall includes: a column 1, located at the vertical part of the support structure of the super-large glass curtain wall, providing longitudinal support force; a cross beam 2, located at the horizontal part of the support structure of the super-large glass curtain wall, arranged on both sides of the column, providing transverse bearing capacity; a sub-frame 3, the sub-frame 3 is detachably connected to the column 1 and / or the cross beam 2; wherein, the column 1 and the cross beam 2 form a cross structure and are detachably connected, and the material of the sub-frame 3 is the same as the material of the column 1 and / or the cross beam 2.

[0032] Both the above-mentioned column 1 and cross beam 2 are made of right-angle solid steel, which can provide stable support force for the super-large glass curtain wall.

[0033] The sub-frame 3 is installed on the column 1 or the cross beam 2 to form a T-shaped steel structure. The T-shaped steel has a unique shape and excellent performance, and can provide reliable support for the curtain wall system. In architectural design, the use of T-shaped steel can improve the stability and safety of the support structure of the super-large glass curtain wall and ensure long-term use. The sub-frame 3 and the column 1 or the cross beam 2 are detachably connected, which is convenient for construction and later maintenance work, improves the construction flexibility. At the same time, it also allows the T-shaped steel structure to better adapt to environmental changes, such as temperature changes, earthquakes, etc.

[0034] In order to avoid the rusting of the T-shaped steel and ensure the aesthetic property of the T-shaped steel, an appropriate method can be adopted to prevent the surface of the column 1, the cross beam 2 and the sub-frame 3 from rusting and corrosion, resulting in the decline of the overall aesthetic property and safety. For example, environmental control and regular maintenance can be adopted. Preferably, coating protection is used. The coating can form a physical barrier on the surface of the T-shaped steel, which can effectively prevent rainwater or oxygen from directly contacting the surface of the T-shaped steel and damaging the material surface. Secondly, the coating can also enhance the aesthetic property of the T-shaped steel. The coating on the surface of the above-mentioned T-shaped steel can be achieved by spraying fluorocarbon on the surface of the T-shaped steel. After fluorocarbon spraying, the corrosion resistance and wear resistance of the surface can be significantly improved, and it can be applied to harsh environments such as humidity, acid rain, and salt spray. Secondly, after fluorocarbon spraying, the surface is smooth and delicate, enhancing the aesthetic property of the T-shaped steel.

[0035] The support structure of the extra-large glass curtain wall proposed in this application adopts a cross structure in which the columns and beams are detachably connected, and is detachably connected to the sub-frame of the same material. This design greatly improves the modularity and flexibility of the structure, and simplifies the installation and maintenance processes. By providing longitudinal support force through the columns and transverse bearing capacity through the beams, the overall structure achieves excellent stability and bearing capacity. At the same time, the consistency of materials ensures the matching of the coefficient of thermal expansion, reduces thermal stress, and improves the durability and safety of the structure.

[0036] As Figure 1 shown, in order to improve the integrity of the column 1 and the beam 2 and ensure the stability of the support structure of the extra-large glass curtain wall, specifically, the connection between the column 1 and the beam 2 can be an elastic detachable connection. The above elastic detachable connection can adopt a spring pin 9. Using the spring pin 9 can improve the construction speed and efficiency. Relying on the elastic force to connect between the column 1 and the beam 2 can ensure a more stable connection between the column 1 and the beam 2, thereby improving the stability of the support structure of the extra-large glass curtain wall. Since the spring pin 9 allows a certain range of position adjustment and fine-tuning, it helps to adapt to the irregular shape on site or reduce the size difference, improves the installation accuracy, and can also reduce the problem of stress concentration caused by temperature changes. The support structure of the curtain wall connected by the spring pin 9 is more delicate and beautiful in appearance, meeting the aesthetic requirements of modern architecture.

[0037] As Figure 2 and Figure 3 shown, in order to connect the sub-frame 3 with the column 1 or the beam 2 to form a T-shaped steel structure, the sub-frame 3 can be in an appropriate form to meet the purpose of connecting with the column 1 or the beam 2. In order to ensure the accurate connection position of the sub-frame 3 with the beam 2 or the column 1, specifically, the sub-frame 3 can have a first groove and a second groove, and the first groove is in contact with and detachably connected to the column 1 and / or the beam 2. The above column 1 or beam 2 has a convex structure that matches the first groove of the sub-frame 3. During installation, the convex structure of the column 1 or beam 2 is connected in cooperation with the first groove. In order to ensure that the sub-frame 3 does not displace on the column 1 or the beam 2, snap connection or bonding can be used, preferably bolt connection. The bolt can fix the sub-frame 3, which is convenient for later adjustment and repair. The bolt can be in an appropriate form, for example, it can be a countersunk screw 10.

[0038] As Figures 5 - 6As shown, according to the second aspect of the present application, an extra-large glass curtain wall is proposed. The extra-large glass curtain wall includes: a support structure for the extra-large glass curtain wall, which provides a stable support structure for the extra-large glass curtain wall; a pressing plate 4 for fixing the extra-large glass curtain wall; a glass panel 5, the edge of the glass panel 5 is fixed between the support structure of the extra-large glass curtain wall and the pressing plate 4; wherein, the support structure of the extra-large glass curtain wall is the support structure of the above-mentioned extra-large glass curtain wall. The above glass panel 5 can be selected according to actual applications, for example, it can be tempered glass, semi-tempered glass, laminated glass, insulating glass, etc. As Figure 4 As shown, in order to enhance the friction between the glass panel and the support structure of the extra-large glass curtain wall, a sealing strip 11 is also provided between the glass panel and the support structure of the extra-large glass curtain wall. The sealing strip 11 can effectively disperse stress, compensate for thermal expansion and contraction, and at the same time provide multiple functions such as shock absorption, sound insulation, waterproofing and insulation, extend the service life of the extra-large glass curtain wall, comprehensively improve the safety, performance and aesthetics of the structure, and is a key strategy to ensure the system stability and extend the service life in the design of modern extra-large glass curtain walls. The above sealing strip 11 can be made of appropriate materials, for example, it can be rubber, silicone or polyurethane, preferably rubber. The rubber can be natural rubber, nitrile rubber, fluororubber, preferably ethylene propylene diene monomer (EPDM) rubber. EPDM rubber is suitable for use in a variety of chemical environments, has a relatively wide applicable temperature range, and also has good anti-aging performance. In addition, EPDM rubber has a good effect of blocking water and water vapor and has good sealing performance.

[0039] The above support structure provides a solid foundation for the extra-large glass curtain wall, ensuring the stability and integrity of the structure of the extra-large glass curtain wall; fixing the edge of the glass panel 5 between the support structure and the pressing plate 4 can effectively prevent the glass panel 5 from falling off under the action of wind pressure or other external forces, enhancing the safety of the extra-large glass curtain wall, and also providing good sealing performance to prevent air leakage and rainwater penetration. Moreover, it can also be applicable to glass panels 5 of different thicknesses and sizes. In addition, it can also provide a neat and smooth appearance, improving the aesthetics.

[0040] In order to better fix the glass panel 5, specifically, the pressing plate 4 can be a cross structure and the cross structure formed by the pressing plate 4 and the columns 1 and / or beams 2 of the support structure of the extra-large glass curtain wall overlaps and covers. The above cross-structured pressing plate 4 can provide additional support for the glass panel 5, enhancing the connection strength with the support structure and also improving the stability of the entire extra-large glass curtain wall. The above pressing plate 4 can be connected to the support structure of the extra-large glass curtain wall in an appropriate form, such as Figures 6 - 8As shown, specifically, the pressing plate 4 and the supporting structure of the super-large glass curtain wall can be detachably connected, for example, they can be bolted, and the bolted connection can use T-bolts 12, which pass through the gap between the glass panels 5, are perpendicular to the pressing plate 4 and the supporting structure, and connect the pressing plate 4 to the supporting structure, thereby fixing the glass panels 5, and the T-bolts 12 can also effectively transmit torque to ensure stability and tightening effect. The shape of the pressing plate 4 can be a concave structure, and the bottom of the concave structure is in contact with the glass panel 5. In order to enhance the sealing between the pressing plate 4 and the glass panel 5 and the safety and stability of the overall super-large glass curtain wall structure, a seal is also provided at the contact portion between the pressing plate 4 and the glass panel, and the seal can be in an appropriate form, for example, it can be rubber.

[0041] like Figure 4 and Figure 5 As shown, in order to provide support and stability for the glass panel 5, specifically, the super-large glass curtain wall may further include a bearing structure for the glass panel, and the bearing structure for the glass panel 5 is arranged in the outer groove of the sub-frame 3 on the supporting structure crossbeam 2 of the super-large glass curtain wall, so as to provide support for the glass panel 5. The bearing structure for the glass panel 5 is arranged in the groove on the outer side of the sub-frame 3, so as to ensure that the glass panel 5 remains stable under various external forces (such as wind pressure and deadweight), thereby improving the overall safety of the super-large glass curtain wall.

[0042] The width of the bearing structure of the glass panel can be adjusted according to the thickness of the glass panel 5 to provide better support. Specifically, the width of the bearing structure of the glass panel can be consistent with the width of the glass panel 5. The length of the supporting structure of the glass panel can be an appropriate length to meet the support force of the glass panel 5.

[0043] To ensure the safe and stable use of the glass panel 5, specifically, the bearing structure of the glass panel 5 may include: a support plate 6 for providing support to the glass panel 5; a cushion block 7 placed above the support plate 6 for adjusting the position of the glass panel 5. The above-mentioned support plate 6 can be made of an appropriate material, such as alloy, stainless steel, ceramic or stone, preferably steel. The material of steel is relatively hard and can provide good support. Secondly, using steel can avoid corrosion caused by different materials between the support structure of the super-large glass curtain wall and the pressing plate 4, which affects the structural stability of the super-large glass curtain wall. The above-mentioned cushion block 7 can be made of an appropriate material, such as rubber, polyurethane, polyamide, etc., preferably polyvinyl chloride (PVC); the support plate 6 can provide better support force to the glass panel 5, and the cushion block 7 can evenly distribute the weight of the glass panel 5 on the support plate 6, and can also reduce the direct contact between the glass and the steel support plate 6, avoiding uneven glass temperature caused by metal heat conduction and reducing thermal stress; the cushion block 7 can also help absorb vibration and reduce the impact of wind or external noise on the glass panel 5. Secondly, the cushion block 7 can also help correct and finely adjust the position of the glass panel 5 to ensure its precise alignment during installation.

[0044] For the overall aesthetics of the super-large glass curtain wall, specifically, the T-shaped super-large glass curtain wall may further include a cover 8 detachably arranged outside the pressing plate 4 and overlapping with the pressing plate 4. The cover 8 is connected to the protrusions on both sides of the pressing plate 4 by snap-fit. The snap-fit has no connecting structure, which can enhance the aesthetic effect of the super-large glass curtain wall. The setting of the cover 8 can also further enhance the sealing performance of the super-large glass curtain wall, prevent moisture or dust from penetrating through the gap between the pressing plate 4 and the glass panel 5, and improve the waterproof and dustproof capabilities. The cover 8 can also protect the internal connectors from external factors. The cover 8 is made of the same material as the support structure of the super-large glass curtain wall to avoid the situation of electrochemical corrosion, and the outside of the cover 8 is also treated with fluorocarbon spraying.

[0045] The support structure of the super-large glass curtain wall and the super-large glass curtain wall proposed in this application have the same material for the support structure of the super-large glass curtain wall, which can ensure a consistent coefficient of thermal expansion, contribute to maintaining the integrity and stability of the structure during temperature changes; structures with the same material have similar deformation characteristics when stressed, which helps to achieve a more uniform stress distribution; it can also effectively avoid the phenomenon of electrochemical corrosion caused by contact between different materials, so as to improve the overall performance of the structure. Using a structure of a single material makes the maintenance between components more convenient.
