Technical Field
[0001] This utility model relates to an interlocking horizontal beam connection structure for a sloping unit curtain wall, belonging to the field of building curtain wall technology. Background Technology
[0002] In building curtain wall engineering, sloping unitized curtain walls are widely used due to their unique architectural aesthetics and functional applications. The upper and lower horizontal beams of its unit panels bear key mechanical roles: the lower horizontal beam, as the main load-bearing component of the glass panel, needs to withstand gravity loads; while the upper horizontal beam prevents the glass from falling through tension, and the two have significantly different stress characteristics.
[0003] In existing technologies, the upper and lower horizontal beams are generally fixed by interlocking with the same profile. This design has the following drawbacks: First, the cross-sectional dimensions of the lower horizontal beam are not optimized for gravity bearing, and the same profile may bend and deform due to insufficient strength, affecting the safety of the curtain wall structure. Second, the upper horizontal beam mainly bears tensile force, and the large cross-section profile results in material waste and increased manufacturing costs. Third, the traditional interlocking connection method has a small contact area and low force transmission efficiency, and is prone to loosening under long-term vibration, wind loads, etc., posing a risk of panel falling. Therefore, a new solution is needed to address the above problems. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an interlocking horizontal beam connection structure for a sloping unit curtain wall.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an interlocking horizontal beam connection structure for a sloping unit curtain wall, comprising columns, an upper horizontal beam, a lower horizontal beam, and glass panels; the front end of the lower horizontal beam is integrally formed with a first glass subframe, and the lower end of the glass panel is fixedly installed on the lower horizontal beam through the first glass subframe; the front end of the upper horizontal beam is integrally formed with a second glass subframe, and the upper end of the glass panel is fixedly installed on the upper horizontal beam through the second glass subframe; the rear ends of both the upper and lower horizontal beams are connected and fixed to the columns;
[0006] The width of the lower crossbeam is greater than the width of the upper crossbeam, and the lower crossbeam extends to one side of the adjacent upper crossbeam so that the lower side of the lower crossbeam is flush with the lower side of the adjacent upper crossbeam; a receiving cavity is provided on the lower front end of the lower crossbeam, and the rear end of the adjacent upper crossbeam is embedded in the receiving cavity of the lower crossbeam and connected and fixed to the lower crossbeam.
[0007] Preferably, the lower crossbeam has a cavity inside, and a steel insert is fixedly installed inside the cavity of the lower crossbeam. The steel insert has multiple horizontally penetrating cavities.
[0008] Preferably, the contact area between the steel insert and the lower crossbeam is filled with multiple sections of structural adhesive.
[0009] Preferably, a first aluminum alloy buckle cover is provided on the first glass subframe, one end of the first aluminum alloy buckle cover is snapped onto the first glass subframe, and the other end of the first aluminum alloy buckle cover presses against the lower end of the glass panel from the outside.
[0010] The second glass subframe is provided with a second aluminum alloy buckle cover. One end of the second aluminum alloy buckle cover is snapped onto the second glass subframe, and the other end of the second aluminum alloy buckle cover presses against the upper end of the glass panel from the outside.

[0012] Preferably, a flexible pad is provided at the position where the lower end of the glass panel contacts the first glass subframe.
[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0014] 1. The present invention discloses an interlocking horizontal beam connection structure for a sloping unit curtain wall, which adopts an interlocking connection of upper and lower horizontal beams. The rear end of the upper horizontal beam is embedded into the receiving cavity of the lower horizontal beam and fixed with bolts, which greatly increases the contact area between the upper and lower horizontal beams, optimizes the force transmission path, and makes the force transmission more direct and efficient. This connection method can still maintain the stability of the connection under long-term external forces such as vibration and wind load, effectively reducing the risk of panel falling and ensuring the safety of the curtain wall.
[0015] 2. Based on the different stress characteristics of the upper and lower horizontal beams of the unitized curtain wall, this solution significantly enhances the load-bearing capacity and bending strength of the lower horizontal beam by increasing its width and setting a steel insert in its internal cavity.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] As attached Figure 1-2 As shown, the embedded horizontal beam connection structure of the inclined unit curtain wall of this utility model includes a column 1, an upper horizontal beam 2, a lower horizontal beam 3, and a glass panel 4.
[0022] First, construct the overall framework of the unitized curtain wall:
[0023] The rear ends of both the upper crossbeam 2 and the lower crossbeam 3 are fixed to the column 1 by bolts. The column 1 is connected to the embedded parts of the building structure by high-strength bolts. Since the width of the lower crossbeam 3 is greater than the width of the upper crossbeam 2, and the lower crossbeam 3 extends to the side of the adjacent upper crossbeam 2, the lower side of the lower crossbeam 3 must be precisely aligned with the lower side of the subsequently installed upper crossbeam 2 during installation, so that the lower side of the lower crossbeam 3 is flush with the lower side of the adjacent upper crossbeam 2, ensuring that the two are at the same horizontal height.
[0024] The lower crossbeam 3 has a receiving cavity 31 on the lower front side. The rear end of the adjacent upper crossbeam 2 is embedded in the receiving cavity 31 of the lower crossbeam 3 and is connected and fixed to the lower crossbeam 3. During installation, the rear end of the upper crossbeam 2 is embedded in the receiving cavity 31 on the lower front side of the lower crossbeam 3. A positioning pin can be set in the receiving cavity 31 in advance for preliminary positioning. Then, stainless steel bolts are used to pass through the upper crossbeam 2 and the lower crossbeam 3, and the nuts are tightened to make the two firmly connected to form a stable crossbeam frame structure.
[0025] The lower crossbeam 3 has a cavity inside, and a steel insert 32 is fixedly installed inside the cavity of the lower crossbeam 3 to enhance the structural strength of the lower crossbeam 3 and improve the bending resistance of the lower crossbeam 3 under load. Multiple horizontally penetrating cavities 321 are opened on the steel insert 32 to reduce the self-weight of the component.
[0026] Furthermore, the contact points between the steel insert 32 and the lower crossbeam 3 are filled with multiple sections of structural adhesive 7 to enhance the connection strength and integrity between the steel insert 32 and the lower crossbeam 3.
[0027] Compared with the prior art, this application, based on the different stress characteristics of the upper and lower horizontal beams of the unitized curtain wall, significantly enhances the load-bearing capacity and bending strength of the lower horizontal beam 3 by increasing its width and setting a steel insert 32 in its internal cavity. This effectively avoids bending deformation caused by insufficient strength and greatly improves the safety of the curtain wall structure. The upper horizontal beam 2 is designed with a small cross-section. Based on the mechanical characteristics of the upper horizontal beam 2, which mainly bears tensile force, the profile cross-sectional dimensions are reasonably optimized. Under the premise of meeting the mechanical performance requirements, the amount of material used is reduced, the manufacturing cost is lowered, and the efficient use of resources is achieved.
[0028] Meanwhile, this solution adopts an interlocking connection between the upper and lower horizontal beams. The rear end of the upper horizontal beam 2 is embedded into the cavity 31 of the lower horizontal beam 3 and fixed with bolts, which greatly increases the contact area between the upper and lower horizontal beams 3, optimizes the force transmission path, and makes the force transmission more direct and efficient. This connection method can still maintain the stability of the connection under the long-term action of external forces such as vibration and wind load, effectively reducing the risk of panel falling and ensuring the safety of curtain wall use.
[0029] Installation and reinforcement of glass panel 4:
[0030] The front end of the lower crossbeam 3 is integrally formed with a first glass subframe 5, and the lower end of the glass panel 4 is fixedly installed on the lower crossbeam 3 through the first glass subframe 5; the front end of the upper crossbeam 2 is integrally formed with a second glass subframe 6, and the upper end of the glass panel 4 is fixedly installed on the upper crossbeam 2 through the second glass subframe 6. In this embodiment, the upper and lower ends of the glass panel 4 are fixed to the second glass subframe 6 and the first glass subframe 5 respectively with structural adhesive to complete the installation of the glass panel 4.
[0031] To ensure the installation stability of the glass panel 4, a first aluminum alloy cover 8 is provided on the first glass subframe 5. One end of the first aluminum alloy cover 8 is snapped onto the first glass subframe 5, and the other end of the first aluminum alloy cover 8 presses the lower end of the glass panel 4 from the outside. A second aluminum alloy cover 9 is provided on the second glass subframe 6. One end of the second aluminum alloy cover 9 is snapped onto the second glass subframe 6, and the other end of the second aluminum alloy cover 9 presses the upper end of the glass panel 4 from the outside to firmly press the glass panel 4.
[0032] The snap-fit connection between the first aluminum alloy cover 8 and the first glass sub-frame 5 can adopt a commonly used slot and protrusion matching structure in the art. Specifically, a slot is opened on the first glass sub-frame 5, and a protrusion matching the slot is set on the first aluminum alloy cover 8. The protrusion is snapped into the slot to complete the snap-fit connection between the first aluminum alloy cover 8 and the first glass sub-frame 5. The snap-fit structure between the second glass sub-frame 6 and the second aluminum alloy cover 9 is the same as described above, and will not be repeated here. By setting this snap-fit connection structure, the glass surface can be replaced individually, which is convenient for later maintenance.
[0033] Furthermore, a flexible pad 11 is provided at the position where the lower end of the glass panel 4 contacts the first glass subframe 5. The flexible pad 11 can be made of EPDM rubber with high elasticity and aging resistance to effectively buffer the pressure generated by the weight of the glass panel 4 and avoid stress concentration.
[0034] Furthermore, a drip edge 10 is provided between the first aluminum alloy cover 8 and the second aluminum alloy cover 9. During installation, a groove can be preset on the first aluminum alloy cover 8, and then one end of the drip edge 10 is embedded into the preset groove of the first aluminum alloy cover 8, and the other end is covered on the second aluminum alloy cover 9 to ensure that rainwater can be smoothly discharged along the surface of the drip edge 10 and prevent rainwater from seeping into the interior of the curtain wall.
[0035] 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.
