This technology integrates the core elements of green construction, achieving efficient construction, rapid installation, and recyclability through advantages such as factory prefabrication, standardized production, and modular assembly. However, in engineering practice, if traditional curtain wall systems adopt a factory prefabrication and integration method, structural deformation of the modular units during overall transportation and hoisting is often directly transmitted to the curtain wall system, easily causing quality problems such as curtain wall cracking and joint deformation. Therefore, the current industry practice of conservatively adopting the method of installing the main modular structure before on-site curtain wall construction has the following problems:
[0003] 1. The separate construction of the main structure and the curtain wall of the module cannot meet the requirements of prefabrication in the factory and on-site installation of the modular building, resulting in a longer construction period, an increased amount of on-site work, and problems such as high safety risks of working at heights and difficulty in controlling construction quality.
[0004] 2. When installing the curtain wall on the construction site, a large number of holes need to be drilled on-site at the installation nodes between the main structure of the module and the curtain wall, which cannot be pre-treated and is prone to corrosion. Utility Model Content

[0012] Furthermore, both the first connection structure and the second connection structure include,
[0013] A fixed base box is installed on the pre-embedded support of the curtain wall or on the adjacent corner column;
[0014] The bending component is disposed on opposite sides of the fixed base box and is connected to the bending ends of the first curtain wall panel and the second curtain wall panel respectively. The bending component is disposed on the curtain wall embedded support or the adjacent corner column.
[0015] A sealing cover is disposed on the side of the fixed base box away from the curtain wall embedded support and the adjacent corner column, covering the outer side of the first curtain wall panel and the second curtain wall panel.

[0035] like Figure 1 As shown in the figure, this utility model embodiment discloses an integrated curtain wall structure for steel structure modular buildings, including modular units. The modular units are prefabricated steel structures, and curtain wall panels are pre-installed on the modular units. The modular units are then assembled on-site, and adjacent curtain wall panels of adjacent modular units are connected to complete the construction of the entire steel structure modular building. Each modular unit includes corner columns 1 and curtain wall embedded supports 5. The curtain wall embedded supports 5 are arranged parallel to the corner columns 1, and are pre-embedded and fixed during the prefabrication of the modular units. According to the modular building node distribution diagram, the connection nodes in the curtain wall structure include curtain wall panel joint I, curtain wall embedded support node II, and modular unit curtain wall node III. The curtain wall panels include a first curtain wall panel 6 and a second curtain wall panel 7. At curtain wall panel joint I, the first curtain wall panel 6 and the second curtain wall panel 7 are connected to each other. At the curtain wall embedded support node II, a first connecting structure is provided at the end of the first curtain wall panel 6 and the second curtain wall panel 7 away from the joint I between the connecting end curtain wall panels. The first connecting structure is connected to the adjacent first curtain wall panel 6 or second curtain wall panel 7 and fixed to the curtain wall embedded support 5. When assembling adjacent module units, at the curtain wall node III between module units, a second connecting structure is used to connect the adjacent first curtain wall panels 6 and second curtain wall panels 7 of the adjacent module units. The second connecting structure is fixed to the adjacent corner column 1 of the adjacent module units. By setting the first connecting structure and the curtain wall embedded support 5, the curtain wall panels can form an integral whole with the module units.

The C-shaped and Z-shaped curtain wall panels have good resistance to deformation and stability, and can effectively resist external stress during hoisting and transportation. The opposing surfaces of the C-shaped end and the Z-shaped end are connected and sealed by the rubber sealing fastener 8. The rubber sealing fastener 8 is a type of rubber product used for sealing, shock absorption, anti-slip, or cushioning. It can be a sealing strip or a sealing gasket, and is bonded and fixed between the C-shaped end and the Z-shaped end. In this embodiment, by bonding multiple sealing strips, the C-shaped end and the Z-shaped end can be connected, forming a continuous and reliable waterproof sealing system.
[0039] Specifically, such as Figure 4 He Ru Figure 5 As shown, the first curtain wall panel 6 and the second curtain wall panel 7 have bends at their ends near the corner column 1 and the curtain wall embedded support 5. In this embodiment, to facilitate connection with the corner column 1 and the curtain wall embedded support 5, right-angle bends are provided at the ends of the first curtain wall panel 6 and the second curtain wall panel 7 near the corner column 1 and the curtain wall embedded support 5.

The side of the two Z-shaped bending members 13 near the curtain wall embedded support 5 is connected to the curtain wall embedded support 5 with dovetail screws. The sealing cover 11 of the first fixing structure is located on the side of the fixing box 12 away from the curtain wall embedded support 5. The sealing cover 11 covers the outer side of the first curtain wall panel 6 and the second curtain wall panel 7 on both sides near the first curtain wall panel 6 and the second curtain wall panel 7.
[0042] like Figure 5As shown, the second connecting structure is used to connect the bent ends of adjacent first curtain wall panels 6 and second curtain wall panels 7 of adjacent module units. The bent ends of the first curtain wall panels 6 and second curtain wall panels 7 of each module unit near the corner post 1 are connected to the corner post 1. The fixing box of the second connecting structure is fixed to the adjacent corner post 1 of adjacent module units with dovetail screws. The bending member 13 is set as a Z-shaped bending member, and there are two of them, symmetrically arranged on opposite sides of the fixing box 12. The vertical parts of the two Z-shaped bending members are connected to the bent ends of adjacent first curtain wall panels 6 and second curtain wall panels 7 of different module units with dovetail screws. The side of the two Z-shaped bending members near the corner post 1 is connected to the corresponding corner post 1 with dovetail screws. The sealing cover 11 of the second fixing structure is located on the side of the fixing box 12 away from the corner post 1. The sealing cover 11 covers the outer side of the first curtain wall panels 6 and second curtain wall panels 7 on both sides near the first curtain wall panels 6 and second curtain wall panels 7.
[0043] Preferably, in order to facilitate the installation of the sealing cover 11, the sealing cover 11 and the fixed base box 12 are fixed with a buckle on the opposite side, so that the sealing cover 11 can be snapped into the fixed base box 12.
[0044] Preferably, in order to ensure the sealing performance of the sealing cover 11, a sealing gasket 9 is fixed between the sealing cover 11 and the first curtain wall panel 6 and the second curtain wall panel 7.
[0045] Preferably, in order to ensure the airtightness of the connection between each module unit, a sealing strip 16 is fixed between adjacent corner posts 1 of adjacent module units.
[0046] A construction method for an integrated curtain wall structure for steel structure modular buildings, as described above, includes the following steps:
[0047] S1, Prefabricated modular unit
[0048] During the material preparation stage, installation holes 3 are opened on the corner column 1 and the curtain wall pre-embedded support 5. After filling the key components such as the upper beam 2, bottom beam 4, corner column 1 and curtain wall pre-embedded support 5 with rock wool, the upper beam 2, bottom beam 4, corner column 1 and curtain wall pre-embedded support 5 are assembled, welded and fixed to form a modular unit structure frame.
[0049] S2. Install the curtain wall panels at joint I between the curtain wall panels.
[0050] The rubber sealing fastener 8 is bonded and fixed between the C-shaped end of the first curtain wall panel and the Z-shaped end of the second curtain wall panel using special equipment to form a continuous and reliable waterproof sealing system. Then, the curtain wall panels are installed as required.
[0051] S3. Install the curtain wall panels at the pre-embedded support node II of the curtain wall.
[0052] S31, Support and Fixation
[0053] After positioning the fixed base box 12 of the first connecting structure, connect it to the mounting holes 3 on the curtain wall pre-embedded support 5 using dovetail nails; then install the two Z-shaped bent parts 13 symmetrically on both sides of the curtain wall pre-embedded support 5 using dovetail nails.
[0054] S32, Curtain wall panel installation
[0055] Dovetail nails are used to initially fix the bent end of the first curtain wall panel 6 to the corresponding Z-shaped bending piece 13. After adjusting the verticality deviation, the final fixing is achieved by tightening. Then, dovetail nails are used to connect the second curtain wall panel 7 to the corresponding Z-shaped bending piece 13.
[0056] S33, Sealing System
[0057] After the curtain wall panels are installed successfully, the sealing cover 11 is installed. The sealing cover 11 is connected to the fixed base box 12 with snap fasteners, ensuring that it is locked in place. Finally, a sealing gasket 9 is embedded at the joint to form a waterproof barrier.
[0058] S4. Install the curtain wall panels at curtain wall node III between module units.
[0059] This process is divided into two stages: prefabrication in the factory and on-site installation.
[0060] S41, Prefabrication stage in the factory
[0061] Install the curtain wall panels. Secure the Z-shaped bending member 13 to the corner column 1 using dovetail screws. Then, secure the bent end of the first curtain wall panel 6 or the second curtain wall panel 7 closest to the corner column 1 to the corresponding Z-shaped bending member 13 using dovetail screws. After completing the above steps, the curtain wall panels of each module unit are installed. Transport the assembled module unit to the construction site.
[0062] S42, On-site Construction Phase
[0063] Install the curtain wall panels at the curtain wall node III between the module units. Seal the adjacent corner columns 1 of adjacent module units using sealing strips 16. Fix the fixing base box 12 of the second connection structure to the adjacent corner columns 1 using dovetail screws. The sealing cover 11 and the fixing base box 12 are fixedly connected by snap-fit, and a sealing gasket 9 is embedded at the joint.
[0064] The advantages and positive effects of this utility model are:
[0065] 1. It effectively solves the problem of cracking and damage to the curtain wall system caused by deformation during the transportation and hoisting of modular buildings, which prevents factory prefabrication and on-site installation. Based on the steel structure modular building system, it reduces the amount of on-site work and the difficulty of on-site construction by optimizing the design and installation process of the curtain wall panels. At the same time, it reduces the quality problems caused by improper on-site operation, significantly improves the overall performance and construction efficiency of the curtain wall system, and ensures the aesthetics and practicality of the overall building appearance.
[0066] 2. At the joint I between the curtain wall panels, both C-type and Z-type curtain wall panels have good resistance to deformation and stability, and can effectively resist external stress during hoisting and transportation, reducing the problem of curtain wall panel deformation or cracking caused by module deformation.
[0067] 3. At the pre-embedded support node II and the inter-module node III, a combination of a dedicated fixing box and a sealing cover is used to ensure the stability of the connection. The fixing box is installed at the edge of the module unit after the module unit is hoisted, effectively absorbing and adjusting installation errors between module units and ensuring the installation accuracy of the curtain wall panels. The sealing cover covers the fixing box, serving not only an aesthetic purpose but also effectively preventing external factors from corroding the curtain wall system, improving the curtain wall's sealing performance and durability.
