Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and in particular to a large-span curtain wall support and limiting system. Background Technology

[0002] Large-span curtain walls are modern building envelope systems that cover ultra-large spaces such as airports and stadiums. Their core lies in complex steel structures or highly efficient flexible systems, achieving expansive views with a minimalist structure. Utilizing high-performance glass and other materials, they face challenges in structural safety, deformation control, and energy consumption, representing a paradigm of architectural technology that integrates cutting-edge engineering, materials, and digital technologies.

[0003] When constructing a large-span curtain wall on a building with a sloping span, the curtain wall support structure needs to be tilted. After the existing large-span curtain wall support limiting system is installed on the inclined surface of the building, if it is necessary to adjust the angle between the curtain wall and the main body, the positions of the column connectors and the main body connectors need to be adjusted. This requires removing the main body connectors from the main body and going through a series of complex construction measures to reconnect them, which is extremely time-consuming and has a great impact on the construction accuracy of the curtain wall and the stability between the curtain wall and the main body. Summary of the Invention

[0004] This invention discloses a large-span curtain wall support limiting system, which aims to solve the technical problem of poor efficiency and effectiveness of existing large-span curtain wall supports when adjusting the angle with the main building.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A large-span curtain wall support and limiting system includes a building body. Two symmetrical hinged members are fixedly connected to the exterior of the building body. Each hinged member has a column hinged to its exterior. Two symmetrical horizontal beams are fixedly connected between the two columns. Panels are installed on the exterior of the horizontal beams. Column connectors are installed on opposite sides of each of the two columns. Main connectors are installed on the exterior of each column connector. All main connectors are located on the exterior of the building body. An angle adjustment module is installed between each column connector and the main connector. The angle adjustment module includes a threaded rod. A sleeve is installed on the exterior of each threaded rod. The sleeve is fixedly connected to the opposite side of the exterior of each main connector. A fixed seat is movably connected to the end of each main connector away from the column connector. The fixed seat is fixedly connected to the opposite side of the exterior of the building body. A rotating ring is movably connected to the exterior of each sleeve.

[0006] In a preferred embodiment, both threaded rods are fixedly connected to the opposite side of the column connector. Each column connector has a slot near the column end, and a shaft is movably connected within each slot. The shaft is fixedly connected to the opposite side of the column on the same side. An adjusting ring is fixedly connected to the side of the rotating ring near the column connector. The inner wall of the adjusting ring is rotatably connected to the outside of the threaded rod via an external thread. A stabilizing platform is fixedly connected to the outside of the sleeve, and a mounting ring is fixedly connected to the side of the stabilizing platform near the column connector. Each of the two mounting rings has four openings on its outer surface. The mounting grooves are evenly distributed around the circumference. The inner walls of each mounting groove are slidably connected to the outer walls of the rollers on the same side. The inner walls of each mounting ring are also slidably connected to the outer walls of the rotating rings on the same side. Each mounting ring has a sliding ring slidably connected to its outer wall. The inner walls of both sliding rings have tapered grooves that contact the outer walls of the rollers on the same side. A spring surrounds the outer wall of each stabilizing platform. One end of each spring is fixedly connected to the side of the sliding ring closest to the stabilizing platform, and the other end is fixedly connected to the outer wall of the stabilizing platform. The outer walls of both sliding rings are movably connected to... The platform is equipped with push-pull rods, and pull rods are movably connected to the outside of the platform. The ends of the push-pull rods away from the sliding ring are movably connected to the outside of the pull rods on the same side. Each of the two column connectors has an inner groove on its opposite side, and a receiving cylinder is fixedly connected to the inner wall of each groove. Each receiving cylinder has two symmetrical circular holes, and the same short rod is slidably connected to the two circular holes on the same side. Each of the two short rods has two symmetrical inclined blocks, one and one. The inner wall of inclined block one is fixedly connected to the outside of the short rod, and the inner wall of inclined block two is slidably connected to the outside of the short rod. The two inclined blocks are connected, and the side opposite to the inclined block one is attached to each other; both of the two receiving cylinders have arc-shaped grooves on their exteriors, and a lever is slidably connected in each arc-shaped groove. The lever is fixedly connected to the side opposite to the exterior of the inclined block two on the same side. The short rod is surrounded by a spring two. One end of the spring two is fixedly connected to the exterior of the receiving cylinder, and the other end is fixedly connected to the exterior of the short rod. The end of the short rod away from the spring two is fixedly connected to a ring rack. The two shafts are fixedly connected to a toothed ring, and the exterior of the toothed ring is engaged with the exterior of the ring rack on the same side.

[0007] In a preferred embodiment, first carbon fiber cloth is provided on both sides of the two columns, and multiple equidistantly distributed second carbon fiber cloths are provided on the outside of the columns.

The top and bottom of the panel are respectively attached to the opposite side of the two external frames, and horizontal bars are fixedly connected to the upper side of the external frames. A groove is provided at the bottom of the panel, and the inner wall of the groove is slidably connected to the outside of the horizontal bar located below. Two symmetrical angle steels are fixedly connected to the bottom of the two external frames. Each angle steel has a through hole, and a hook-shaped screw is provided in each through hole. The end of the hook-shaped screw near the panel is engaged with the outside of the panel, and double nuts are provided on the outside of the hook-shaped screw. The double nuts are attached to the opposite side of the outside of the angle steel.

By keeping the support structure connected to the building body at all times, the stability of the overall force system of the entire curtain wall structure is ensured. While ensuring the stability of the curtain wall structure, the efficiency of adjusting the angle of the curtain wall support structure is significantly improved. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The large-span curtain wall support limiting system disclosed in this invention is mainly applied to scenarios where the efficiency and effectiveness of existing large-span curtain wall supports in adjusting the angle with the main building are poor.

[0020] Reference Figures 1-8A large-span curtain wall support and limiting system includes a building body 1. Two symmetrical hinged members 2 are bolted to the exterior of the building body 1. Each hinged member 2 is hinged to a column 3. Two symmetrical horizontal beams 6 are bolted between the two columns 3. Panels 5 are installed on the exterior of the horizontal beams 6. Column connectors 7 are installed on opposite sides of each of the two columns 3. Main connectors 8 are installed on the exterior of each column connector 7. All main connectors 8 are located on the exterior of the building body 1. An angle adjustment module 9 is installed between each column connector 7 and the main connector 8. The angle adjustment module 9 includes... The threaded rod 904 is provided with a sleeve 903 on its outside. The sleeve 903 is bolted to the opposite side of the main body connector 8. The end of the main body connector 8 away from the column connector 7 is rotatably connected to a fixed seat 901 through a bearing. The fixed seat 901 is bolted to the opposite side of the building body 1. The sleeve 903 is rotatably connected to a rotating ring 914 through a bearing. The rotating ring 914 has multiple circumferentially distributed fitting grooves 915 on its outside. Rollers 907 are engaged on the inner walls of the multiple fitting grooves 915.

[0021] Specifically, the device utilizes the angle adjustment module 9 to allow the angle of the entire large-span curtain wall support structure to be adjusted after it is installed on the main building 1 without disconnecting the column connectors 7 and the main body connectors 8 from the main building 1. By keeping the support structure connected to the main building 1 at all times, the stability of the overall stress system of the entire curtain wall structure is ensured. While ensuring the stability of the curtain wall structure, the efficiency of adjusting the angle of the curtain wall support structure is significantly improved.

[0022] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6In a preferred embodiment, both threaded rods 904 are bolted to the opposite side of the column connector 7. The end of the column connector 7 near the column 3 has a slot, and a shaft 902 is rotatably connected to each slot via a bearing. The shaft 902 is bolted to the opposite side of the column 3 on the same side. An adjusting ring 910 is bolted to the side of the rotating ring 914 near the column connector 7. The inner wall of the adjusting ring 910 is rotatably connected to the outer side of the threaded rod 904 via an external thread. A stabilizing platform 905 is bolted to the outer side of the sleeve 903, and a mounting ring 906 is bolted to the side of the stabilizing platform 905 near the column connector 7. Four circumferentially distributed... The mounting groove 916 has its inner wall slidably connected to the outer wall of the roller 907 on the same side, and the inner wall of the mounting ring 906 is slidably connected to the outer wall of the rotating ring 914 on the same side. A sliding ring 908 is slidably connected to the outer wall of each mounting ring 906. A tapered groove 909 is formed on the inner wall of each sliding ring 908, and the inner wall of the tapered groove 909 contacts the outer wall of the roller 907 on the same side. A spring 913 surrounds the outer wall of each stabilizing platform 905, and one end of each spring 913 is bolted to the side of the sliding ring 908 closest to the stabilizing platform 905, while the other end is bolted to the outer wall of the stabilizing platform 905. A push-pull rod 911 is rotatably connected to the outer wall of each sliding ring 908 via a bearing. The fixed platform 905 is externally connected to a pull rod 912 via bearings. The end of the push-pull rod 911 away from the sliding ring 908 is rotatably connected to the outside of the pull rod 912 on the same side via bearings. Both column connectors 7 have an inner groove 917 on opposite sides. The inner wall of the inner groove 917 is bolted to a receiving cylinder 918. Each receiving cylinder 918 has two symmetrical circular holes, and the same short rod 919 is slidably connected to the two circular holes on the same side. The two short rods 919 are externally provided with mutually symmetrical inclined blocks 2 921 and inclined block 1 920. The inner wall of inclined block 1 920 is bolted to the outside of the short rod 919, and the inner wall of inclined block 2 921 is slidably connected to the outside of the short rod 919. Block 2 921 is attached to the side opposite to the inclined block 1 920; both receiving cylinders 918 have arc-shaped grooves 922 on their exteriors, and each arc-shaped groove 922 has a sliding connecting block 923. The connecting block 923 is bolted to the side opposite to the exterior of the inclined block 2 921 on the same side. The short rod 919 is surrounded by a spring 2 924. One end of the spring 2 924 is bolted to the exterior of the receiving cylinder 918, and the other end is bolted to the exterior of the short rod 919. The end of the short rod 919 away from the spring 2 924 is bolted to a ring rack 926. The two shafts 902 are bolted to a toothed ring 925. The exterior of the toothed ring 925 is engaged with the exterior of the ring rack 926 on the same side.

[0023] In specific application scenarios, the angle adjustment module 9 is mainly used in the angle adjustment process. That is, the angle adjustment module 9 uses the sleeve 903, threaded rod 904, and adjusting ring 910 to make the device quickly and conveniently change the overall length of the column connector 7 and the main body connector 8, thereby realizing the angle adjustment of the curtain wall support structure. The sliding ring 908, tapered groove 909, roller 907 and fitting groove 915 can limit the threaded rod 904, preventing the threaded rod 904 from rotating unnecessarily due to the gravity, vibration or crosswind of the curtain wall structure, which would cause the angle of the curtain wall structure to change and affect the overall stability of the curtain wall. It should be noted that the device, by including inclined block 2 921, inclined block 1 920, short rod 919, ring rack 926, and toothed ring 925, can provide redundant limiting measures for the curtain wall support frame structure. The ring rack 926, which is connected to the short rod 919, is tightly locked to the toothed ring 925 by inclined block 2 921 and inclined block 1 920, thereby effectively helping the column connector 7 and the main body connector 8 to share the additional force generated by the inclination of the curtain wall support system, and significantly improving the stability and safety of the curtain wall support system.

[0024] Reference Figure 2 , Figure 7 and Figure 8 In a preferred embodiment, first carbon fiber cloth 10 is provided on both sides of the two columns 3, and multiple equidistant second carbon fiber cloth 11 is provided on the outside of the columns 3. The second carbon fiber cloth 11 is attached to the opposite side of the outside of the first carbon fiber cloth 10. The outside of the two crossbeams 6 is connected to the outer frame 4 by bolts. The top and bottom of the panel 5 are respectively attached to the opposite side of the two outer frames 4. The upper side of the outer frame 4 is connected to the horizontal bar 12 by bolts. The bottom of the panel 5 is provided with a groove, and the inner wall of the groove is slidably connected to the outside of the horizontal bar 12 located below. The bottom of the two outer frames 4 is connected to two symmetrical angle steels 13 by bolts. The angle steels 13 are provided with through holes, and hook-shaped screws 14 are provided in the through holes. The end of the hook-shaped screws 14 near the panel 5 is engaged with the outside of the panel 5. The outside of the hook-shaped screws 14 is provided with double nuts 15, and the double nuts 15 are attached to the opposite side of the outside of the angle steels 13.

[0025] In specific application scenarios, the overall structural design of the curtain wall support system is simple and clear, demonstrating versatility and adaptability to span height. Its installation process is simple and quick, greatly improving construction efficiency and effectively adapting to curtain wall deformation under wind vibration. By utilizing horizontal bars 12, angle steel 13, hook-shaped screws 14, and double nuts 15, the anti-jumping and anti-loosening performance of the panel 5 after installation is effectively improved. By standardizing and integrating the entire curtain wall support system, the system efficiency can achieve the expected results in the early stages of project design and assembly. The new column 3 has a pair of opposite sides with a continuous structure of first carbon fiber cloth 10, and multiple ring-shaped second carbon fiber cloths 11 are axially and equally spaced on the outside of the column body. This makes the resulting composite column 3 lightweight, beautiful, high-strength, and strong bending resistance, while also simplifying the production process of the column 3 and saving production costs.

[0026] Working principle: When installing the curtain wall support system on the main building 1, one end of the column 3 is hinged to the hinge 2 pre-installed on the main building 1. At least one pair of opposite side surfaces of the rectangular column 3 are adhered with a first carbon fiber cloth 10. The first carbon fiber cloth 10 is a continuous structure extending axially along the column 3, with its front and rear ends respectively attached to the two edges of the side surface. Several second carbon fiber cloths 11 are adhered at equal intervals axially to the outside of the column 3. Each second carbon fiber cloth 11 is a ring-shaped structure arranged circumferentially along the column body, located outside the first carbon fiber cloth 10. The outer frame 4 is then installed onto the crossbeam 6. After the exterior is installed, angle steel 13 is installed at the bottom of the external frame 4. A through hole is opened at the preset position where angle steel 13 extends out of the external frame 4. The screw part of hook-shaped screw 14 is inserted into the through hole and locked with double nuts 15. The sliding groove at the bottom of panel 5 is placed on the horizontal bar 12. The position of hook-shaped screw 14 is adjusted and the hook part of hook-shaped screw 14 is hung on the edge of panel 5 to complete the installation of panel 5. After the curtain wall support structure is installed on the main building 1, if it is necessary to change the angle between the curtain wall structure and the main building 1, push the lever 923 so that the lever 923 drives the inclined block 2 921 to rotate 180 degrees on the arc groove 922, so that the inclined block 2 921 is no longer symmetrical with the inclined block 1 920. In this state, the inclined surfaces on inclined block 921 and inclined block 920 are parallel to each other. Under the pull of spring 924, short rod 919 drives inclined block 920 to move towards inclined block 921, so that inclined block 921 fits against the inclined surface on inclined block 920. This causes short rod 919 to drive the ring rack 926 to engage with the locking ring 925, grab the pull rod 912 and pull it, so that the push-pull rod 911 drives the sliding ring 908 to overcome the elastic force of spring 913 and slide outside the mounting ring 906. This makes the wider inner wall of the tapered groove 909 and the roller 907 on the same plane. The narrow inner wall of the tapered groove 909 no longer presses against the roller 907, allowing the roller 907 to connect. The locking of the upper fitting groove 915 of the contact and rotating ring 914 allows the rotating ring 914 to rotate freely. The rotating adjusting ring 910 is engaged with the inner thread of the threaded rod 904 through the external thread, thereby causing the threaded rod 904 to extend or retract from the sleeve 903. The extension or shortening of the threaded rod 904, together with the column connector 7 and the main body connector 8, changes the overall length of the column connector 7 and the main body connector 8. Thus, when the fixed position of the fixed seat 901 is fixed, the column connector 7 rotates on the shaft 902, and with the hinge of the hinge 2 and the column 3, the angle between the building body 1 and the column 3 is changed, thus completing the angle between the entire curtain wall support system and the building body 1.

[0027] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
