Description

Technical Field

[0001] This utility model relates to the field of refined steel curtain wall structure technology, and more specifically, to an integrated large-span prefabricated refined steel curtain wall structure. Background Technology

[0002] Modern large public buildings not only pursue open interior spaces, but also require good lighting and transparency. However, traditional aluminum profile curtain walls are difficult to achieve the ideal effect in the case of large spans due to the limitations of strength and rigidity. While ordinary steel structures have high strength, their appearance is rough and cannot meet the requirements of architectural aesthetics. The emergence of refined steel curtain wall structures has solved this contradiction well. It can provide the strength and rigidity required for large spans, and also has a beautiful appearance, which can realize the personalized and artistic expression of architectural design.

[0003] A search revealed that publication number CN220377613U discloses an integrated large-span prefabricated refined steel curtain wall structure, comprising refined steel columns, refined steel beams, curtain wall glass, glass brackets, and subframe components. The refined steel beams are connected and fixed to the sides of the refined steel columns via angle steel connectors. The subframe components include an aluminum alloy base and an aluminum alloy pressure plate; the aluminum alloy base is installed on the refined steel columns, and the aluminum alloy pressure plate is connected and fixed to the aluminum alloy base. The glass brackets are installed on the refined steel columns, supporting the curtain wall glass from the bottom. Using refined steel as the curtain wall keel ensures a small and precise cross-section while significantly improving the keel's bending, compressive, and torsional strength. Furthermore, the prefabricated structure based on refined steel is optimized, effectively solving the problem of excessively long and heavy aluminum alloy keels in existing large-span curtain walls, which easily lead to breakage. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Most existing steel curtain wall structures are connected using bolts or screws. However, during long-term use, bolts and screws may rust or loosen, causing the internal connections of the steel curtain wall structure to become less tight and resulting in local areas detaching from their original positions, thus creating potential hazards. In addition, although the steel columns and beams in traditional steel curtain wall structures will not burn at high temperatures, their strength will drop sharply, making them unable to support the weight of the entire steel curtain wall structure, resulting in collapse and other phenomena.

[0005] Therefore, an integrated, large-span prefabricated, refined steel curtain wall structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides an integrated large-span prefabricated exquisite steel curtain wall structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated large-span prefabricated refined steel curtain wall structure, including a frame assembly, a fixing assembly, a curtain wall assembly, and a second connecting assembly. The fixing assembly is fixedly installed on the side of the frame assembly by bolt connection, and the curtain wall assembly is placed on the side of the frame assembly away from the fixing assembly. The second connecting assembly is installed on the top of the curtain wall assembly.

[0008] Preferably, the frame assembly includes steel columns, steel beams and connecting blocks, with the steel beams placed below the steel columns and the connecting blocks installed on the sides of the steel columns.

[0009] Preferably, the fixing assembly includes a locking bolt, a first nut, a second nut, and a first connecting assembly. The first nut is mounted on the outer diameter surface of the locking bolt, and the second nut is placed below the first nut. The first connecting assembly is placed on the side of the locking bolt, and the first connecting assembly includes an L-shaped connecting plate and a first fixing bolt. The first fixing bolt is mounted on the side of the L-shaped connecting plate. The first nut and the second nut are located on both sides of the L-shaped connecting plate, and a bidirectional clamping force is formed by tightening them.

[0010] Preferably, the curtain wall assembly includes curtain wall glass, a first positioning block and a second positioning block, wherein the first positioning block is installed on the side of the curtain wall glass and the second positioning block is placed below the first positioning block.

[0011] Preferably, the second connecting assembly includes a second fixing bolt, a first anti-slip pad, a second anti-slip pad, and a resistor transformer sheet, wherein the first anti-slip pad is placed on the outer diameter surface of the second fixing bolt, the second anti-slip pad is placed below the first anti-slip pad, and the resistor transformer sheet is placed below the second fixing bolt.

[0012] Preferably, the steel beam (6) and the steel column (5) are connected by a prefabricated tenon and mortise structure, and the tenon and mortise joint is filled with elastic sealant. The second connecting component (4) passes through the top of the curtain wall component (3) and is fixedly connected to the frame component (1) to form an integrated tensile and compressive structure.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with existing technologies, this integrated large-span prefabricated refined steel curtain wall structure can detect the prestress applied by the second fixing bolt to the surface of the second positioning block in real time by placing a resistor transformer under the second connecting component. The detected value is transmitted to the control panel, which analyzes the prestress applied by the second fixing bolt to the surface of the second positioning block. When the prestress is less than a certain critical value, the control panel will promptly provide feedback to the construction personnel, allowing them to carry out emergency repairs. This ensures that loose areas of the steel curtain wall structure can be repaired in a timely manner, thereby preventing accidents caused by local displacement or collapse.

[0017] 2. Compared with existing technologies, this integrated large-span prefabricated refined steel curtain wall structure applies a uniformly thick layer of fireproof paint to the surface of the frame components. This gives the frame components not only good fire resistance but also good water resistance and corrosion resistance. It forms a hard protective film on the steel surface, isolating the frame components from the external environment. In the event of a fire, it can slow down the transfer of heat on the steel and decompose into non-combustible gases at high temperatures, diluting the oxygen concentration in the combustion zone and thus reducing the spread of the fire.

[0026] When workers install the steel curtain wall structure, they first need to use the fixing component 2 to connect and fix the frame component 1, and then fix the curtain wall component 3 to the frame component 1 through the second connecting component 4. After the precision steel curtain wall structure has been used for a period of time, the second connecting component 4 may become loose due to rust on its outer surface or due to vibration of the building itself. At this time, it will report the loosening to the control panel, and the control panel will convert the loosening into data and report it to the construction personnel. At this time, the construction personnel can promptly repair or replace the second connecting component 4 that is about to become loose based on the reported data information.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the frame assembly 1 includes a steel column 5, a steel beam 6, and a connecting block 7. The steel beam 6 is placed below the steel column 5, and the connecting block 7 is installed on the side of the steel column 5 by bolts. When the worker fixes the frame assembly 1, he needs to fix the steel column 5 and the steel beam 6 by fixing the fixing component 2, and then fix the connecting block 7 to the steel column 5 by bolts.

[0030] In a preferred embodiment, the fixing component 2 includes a locking bolt 8, a first nut 9, a second nut 10, and a first connecting component 11. The first nut 9 is mounted on the outer diameter surface of the locking bolt 8, and the second nut 10 is placed below the first nut 9. The locking bolt 8, the first nut 9, and the second nut 10 are connected by threads. The first connecting component 11 is placed on the side of the locking bolt 8. The first connecting component 11 includes an L-shaped connecting iron plate 12 and a first fixing bolt 13. The first fixing bolt 13 is mounted on the side of the L-shaped connecting iron plate 12. When the worker assembles the frame component 1, the locking bolt 8 needs to be placed into the frame component 1, and then the two ends of the locking bolt 8 are fixed by threads using the first nut 9 and the second nut 10. Then, the L-shaped connecting iron plate 12 is placed at the connection point of the frame component 1 and fixed to the outer surface of the frame component 1 by the first fixing bolt 13. The first nut 9 and the second nut 10 are located on both sides of the L-shaped connecting iron plate 12, and a bidirectional clamping force is formed by tightening.

[0031] In a preferred embodiment, the curtain wall assembly 3 includes a curtain wall glass 14, a first positioning block 15, and a second positioning block 16. The first positioning block 15 is bolted to the side of the curtain wall glass 14, and the second positioning block 16 is placed below the first positioning block 15. When the worker installs the curtain wall assembly 3, the worker needs to bolt the first positioning block 15 and the second positioning block 16 to the upper and lower ends of the curtain wall glass 14, respectively.

[0032] In a preferred embodiment, the second connecting assembly 4 includes a second fixing bolt 17, a first anti-slip pad 18, a second anti-slip pad 19, and a resistor transformer 20. The first anti-slip pad 18 is placed on the outer diameter surface of the second fixing bolt 17, the second anti-slip pad 19 is placed below the first anti-slip pad 18, and the resistor transformer 20 is placed below the second fixing bolt 17. When workers connect the curtain wall assembly 3 and the frame assembly 1, they need to first place the first anti-slip pad 18 and the second anti-slip pad 19 onto the second fixing bolt 17. The outer diameter surface of bolt 17 is then screwed into the bolt holes of the first anti-slip pad 18, the second anti-slip pad 19, and the frame assembly 1 using a wrench to achieve fixation. When the connection between the frame assembly 1 and the curtain wall assembly 3 becomes loose after a period of use, the resistance transformer 20 at the bottom of the second fixing bolt 17 will promptly feed data back to the control panel due to the reduction of the internal prestress of the second connecting assembly 4. The control panel will organize the data and transmit it to the construction personnel for timely repair.

[0033] The steel beam 6 and the steel column 5 are connected by a prefabricated mortise and tenon structure, with elastic sealant filling the mortise and tenon joints. The second connecting component 4 passes through the top of the curtain wall component 3 and is fixedly connected to the frame component 1, forming an integrated tensile and compressive structure. The first positioning block 15 and the second positioning block 16 are both made of rubber and are respectively embedded in the top and bottom grooves of the curtain wall glass 14, with the outer sides of the first positioning block 15 and the second positioning block 16 fitting with the frame component 1 with a clearance. The resistor transformer 20 is made of copper-aluminum composite material, and its two ends are electrically connected to the metal frame of the curtain wall component 3 and the frame component 1, respectively.

[0034] The working process of this utility model is as follows: First, when the worker installs the steel curtain wall structure, he needs to use the fixing component 2 to connect and fix the frame component 1. First, he needs to put the locking bolts 8 into the holes of the steel column 5 and the steel beam 6. Then, the steel column 5 and the steel beam 6 are limited at both ends of the locking bolts 8 by the first nut 9 and the second nut 10. Then, the L-shaped connecting iron plate 12 of the first connecting component 11 is placed at the connection between the steel column 5 and the steel beam 6, and fixed to the outer surface of the frame component 1 by the first fixing bolt 13. Finally, the connecting block 7 is fixed to the steel column 5 by bolts. After the frame component 1 is fixed, the worker needs to assemble the curtain wall component 3 and install it on the outer surface of the frame component 1. First, the worker needs to install the first positioning block 15 and the second positioning block 16 on the curtain wall glass by bolts. The upper and lower ends of the glass 14 are then placed, and the first anti-slip pad 18 and the second anti-slip pad 19 of the second connecting component 4 are placed on the outer diameter surface of the second fixing bolt 17. The second fixing bolt 17 is then screwed into the bolt holes of the first anti-slip pad 18, the second anti-slip pad 19 and the frame component 1 with a wrench to achieve fixation. After the precision steel curtain wall structure has been used for a period of time, the second connecting component 4 may become loose due to rust on its outer surface or due to vibration of the building itself. At this time, the resistor transformer 20 will feed back the loosening situation to the control panel, and the control panel will convert the loosening situation into data and reflect it to the construction personnel. At this time, the construction personnel can promptly repair and replace the second connecting component 4 that is about to become loose based on the reflected data information. The above is the working principle of this integrated large-span prefabricated precision steel curtain wall structure.
