Description

Technical Field

[0001] The invention discloses an assembled frame curtain wall and an installation method thereof, belonging to the technical field of fixed buildings. Background Art

[0002] Prefabricated buildings shift much of the traditional on-site construction work to the factory. Building components and accessories (such as floor slabs, wall panels, stairs, and balconies) are manufactured in the factory, transported to the construction site, and assembled and installed on-site using reliable connections. Prefabricated buildings primarily include prefabricated concrete structures, steel structures, and modern wood structures. They exemplify modern industrialized production methods due to their standardized design, factory-based production, prefabricated construction, information-based management, and intelligent applications. As prefabricated buildings are widely promoted, increasing assembly speed and reducing costs while ensuring precision are pressing challenges.

[0003] Traditional framed curtain walls are popular due to their cost advantages. They are relatively simple to design, calculate, and manage, and can tolerate large installation errors, offering advantages such as ease of manufacture and flexibility in installation. However, the majority of curtain wall components are processed and installed on-site, resulting in poor machining accuracy. The entire curtain wall must be installed from the top to the bottom of the building structure after civil construction is complete, using tools such as scaffolding, leading to lengthy installation times and poor precision. Because most curtain wall components are assembled and installed on-site, the resulting quality is relatively rough and installation efficiency is low.

[0004] According to the calculation rules for the prefabrication rate of prefabricated buildings, unitized curtain walls are prefabricated exterior enclosure components, meaning they are non-load-bearing. Due to their mature technology and rapid construction schedule, unitized curtain walls are widely used in prefabricated buildings. The most common method for traditional unitized curtain walls involves connecting left and right unit panels via vertical frames (male and female aluminum alloy profiles). Unit panels must be installed in a clockwise or counterclockwise order, offering advantages such as high machining precision and efficient installation. However, if a unit panel is damaged or not delivered, the orderly installation method cannot proceed properly, impacting the overall construction schedule. Therefore, efficient installation of unitized curtain walls presupposes that all unit panels are intact. Furthermore, the unit panels of traditional unitized curtain walls are split into separate sections. For example, when connecting horizontal and vertical frames, the horizontal and vertical frame profiles must be flush in the depth direction. This increases the cost by approximately 400-500 yuan per square meter compared to conventional frame curtain walls. This cost factor has limited the application of unitized curtain walls in prefabricated buildings.

[0005] In summary, the present invention aims to combine the advantages of quick installation and high processing precision of the units with the cost advantage of the frame curtain wall to propose an assembled frame curtain wall. Summary of the Invention

[0006] The purpose of the present invention is to address the deficiencies of the above-mentioned background technology and provide an assembled frame curtain wall and an installation method thereof. Combining the advantages of quick installation and high processing precision of the unit curtain wall with the cost advantage of the frame curtain wall, it not only improves the quality and efficiency of the curtain wall and reduces energy efficiency, but also ensures the waterproofness, airtightness and wind pressure resistance required by the curtain wall itself, thereby achieving the purpose of quick installation, improved processing precision and reduced cost, and solving the technical problems of traditional frame curtain walls that are restricted in their application in assembled buildings due to poor installation precision and long installation time, as well as the technical problems of existing unit curtain walls that are restricted in their application in assembled buildings due to high cost.

[0007] The present invention adopts the following technical solutions to achieve the above-mentioned purpose:

[0008] The assembled frame curtain wall includes: large unit panels installed on the wall in odd-numbered rows and small unit panels installed on the wall in even-numbered rows. The columns of the large unit panels are vertical frame structures with spaces for embedding small unit panel installation components. The small unit panels are hung on the columns of two adjacent rows of large unit panels.

[0009] Furthermore, in the assembled frame curtain wall, water trough materials are installed on the upper crossbeams of the large unit panels to limit the lateral displacement of the large unit panels between adjacent layers.

[0010] Furthermore, in the prefabricated frame curtain wall, the small unit panel includes a glass panel and a sub-frame. The sub-frame has an extension portion that is buckled with the aluminum alloy support plate. The glass panel is installed in a groove formed by buckling the sub-frame and the aluminum alloy support plate and is bonded to the sub-frame through silicone structural sealant. The sub-frame is provided with screw holes for installing aluminum alloy hangers. The small unit panel is hung in the small unit hanging groove of the adjacent large unit panel column through the aluminum alloy hanger installed on the sub-frame.

[0011] Furthermore, in the assembled frame curtain wall, the upper beams and lower beams of the large unit panels between adjacent layers are spliced ​​to form a frame structure with a cavity, and sealant is applied in the gap between the frame structure and the glass panel.

[0012] Furthermore, in the assembled frame curtain wall, the columns of the large unit panels are installed on the wall through adjustable embedded parts and aluminum connectors.

[0013] Furthermore, in the assembled frame curtain wall, small unit noise reduction strips are stuffed into the gaps between the sub-frames of the small unit panels and the columns of the large unit panels.

[0014] Furthermore, in the prefabricated frame curtain wall, the extension of the sub-frame of the small unit panel is connected to the column through a limiting angle bracket.

[0015] The installation method of the prefabricated frame curtain wall is to complete the installation of odd-numbered columns of large unit panels by installing the columns of large unit panels on the wall through adjustable embedded parts and aluminum connectors, and to complete the installation of even-numbered columns of small unit panels by hanging the small unit panels on the columns of adjacent large unit panels through small unit panel installation hangers. After hanging the small unit panels on the adjacent large unit panel columns, tighten the aluminum alloy hanging code that passes through the small unit hanging slot on the large unit panel column.

[0016] Furthermore, in the installation method of the assembled frame curtain wall, after the lower large unit panels are installed, the water trough material is installed on the upper crossbeam of the lower large unit panels.

[0017] Furthermore, in the installation method of the prefabricated frame curtain wall, when installing large unit panels of different layers, temporary triangular angle steel supports are added between the aluminum connectors for installing the columns of the large unit panels between adjacent layers.

[0018] The present invention adopts the above technical solution and has the following beneficial effects:

[0019] (1) A prefabricated frame curtain wall with spaced-apart installations and shared columns for large and small unit panels is proposed. There is no need to install keels on each unit curtain wall panel, which reduces the weight of materials. Small single panels are reliably attached to large unit panels through aluminum alloy hangers, thus reducing costs while ensuring the stability of the curtain wall unit structure.

[0020] (2) After the installation of the lower large unit panels is completed, the water trough material is installed on the upper crossbeam of the installed large unit panels. This can not only eliminate the influence of expansion and contraction deformation on the stability of the inter-layer panels, but also limit the front and rear positions of the inter-layer large unit panels, and at the same time absorb the installation errors of the large unit panels between different layers.

[0021] (3) The upper and lower beams of the large unit panels between the layers are spliced ​​to form a frame structure with a cavity. Sealant is applied in the gap between the frame structure and the glass panel to reduce the process sealing cavity and save aluminum.

[0022] (4) The prefabricated frame curtain wall proposed in the present invention can realize the disordered installation of horizontal panels, overcoming the inherent defect of the unitized curtain wall that must be installed in an orderly manner, and improving the on-site installation efficiency while ensuring the processing accuracy.

[0032] The technical solution of the invention is described in detail below with reference to the accompanying drawings.

[0033] The assembled frame curtain wall disclosed in the present invention is as follows Figures 1 to 5 As shown, the structure includes large unit panels and small unit panels that share columns 3 with the large unit panels. The large unit panels are installed on the wall 16 in odd-numbered rows using adjustable embedded parts 13. The small unit panels are hung on the large unit panels using small unit panel mounting hangers 12, so that the small unit panels are installed in even-numbered rows on the wall 16. Compared with traditional unit curtain walls with fully split mullions, the large and small unit panels share a single mullion, eliminating the need to install keels on each unit curtain wall panel, reducing material weight per meter.

[0034] The large unit panels are assembled in the factory. Figure 1 、 Figure 2 、 Figure 4 As shown, it includes: glass panels 1 and columns 3 that are integrally formed in the factory. After the large unit panels are transported to the site, they are installed on the wall through odd-numbered rows of adjustable embedded parts. A water trough material 4 is installed at one end of the crossbeam 7 on the current large unit panel. After completing the installation of one layer of large unit panels, the installation of the next layer of large unit panels is carried out until the installation of a row of large unit panels is completed. The water trough material 4 is used to limit the lateral displacement of the upper (or lower) large unit panels when installing large unit panels between different layers. It can not only eliminate the influence of expansion and contraction deformation on the stability of the inter-layer panels, but also provide front and rear limit and absorb installation errors. As shown in Figure 7 (a), Figure 2As shown, the column is a vertical frame structure with a space for embedding the small unit plate installation component, and the vertical frame structure is provided with a small unit hanging groove 9.

[0035] The small unit panels are assembled in the factory, and the assembled large unit panels are as follows. Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 As shown, it includes: a glass panel 1, a sub-frame 5. The sub-frame 5 has an extension portion that is buckled with the aluminum alloy support plate as shown in Figure 7 (b). The glass panel 1 is installed in the groove formed by buckling the sub-frame 5 and the aluminum alloy support plate and is bonded to the sub-frame 5 through silicone structural sealant. The sub-frame 5 is provided with screw holes for installing aluminum alloy hangers 2. The small unit panel is hung in the small unit hanging groove 9 through the aluminum alloy hanger 2 installed on the sub-frame 5. The gap between the sub-frame 5 and the column 3 is filled with a small unit noise reduction strip 10. As shown in Figure 7 (c) and Figure 7 (d), the lower crossbeam and the upper crossbeam are spliced ​​to form a frame structure with a cavity. The gap between the frame structure and the glass panel is filled with sealant to reduce the process of sealing the cavity. Compared with the unit curtain wall that achieves the airtight line, watertight line, and dusttight line by lengthening the cavity length and setting a plug-in wing structure, it saves aluminum. Figure 1 As shown, in the small unit panel, the extension of the sub-frame 5 is connected to the column 3 through the limiting angle code 8, which can not only meet the upper and lower and front and rear limiting requirements, but also enhance the flatness of the panel surface during installation.

[0036] like Figure 5 、 Figure 6 As shown, after the large unit panels and small unit panels assembled in the factory are transported to the site, the columns of the large unit panels are installed on the wall 16 through the adjustable embedded parts 13 and the aluminum connectors 14. After the small unit panels are hung on the columns 3 through the small unit panel installation hangers 12, the aluminum alloy hanging code 2 in the small unit hanging slot 9 is tightened to complete the installation of the small unit panels. The hanging part of the small unit panel installation hanger 12 is padded with nylon noise reduction spacer 11. Temporary triangular angle steel supports 15 are added between the layers of the large unit panels to enhance the column rigidity during hoisting and reduce deformation. The installed assembled frame curtain wall is as follows Figure 8 shown.

[0037] In summary, the prefabricated frame curtain wall disclosed in the present invention completes the assembly of unit panels in the factory, and the on-site assembly installation by hanging small unit panels on large unit panels can not only ensure the processing accuracy but also realize the disordered installation of horizontal panels, improve the on-site installation efficiency, and reduce the usage area and cycle of the on-site stacking site.
