Description

Technical Field

[0001] This invention relates to the field of curtain walls, and specifically to a construction method and processing method for a steel frame structure used in curved curtain wall designs. Background Technology

[0002] Building curtain walls are the external envelope of buildings and an indispensable decorative means for achieving architectural aesthetics today. Currently, architectural designs are increasingly trending towards novelty, uniqueness, and grandeur, and to ensure these aesthetics are realized, the supporting steel structures and connections of building curtain walls are becoming more complex.

[0003] Nowadays, some shopping malls or hotels, in pursuit of unique structural designs, are no longer keen on traditional, conventional flat glass curtain walls, but rather on curved, three-dimensional curtain wall designs to attract consumers' attention.

[0004] Please see Figure 1 As shown, the related technology discloses a large-span multi-curved cantilever curtain wall 26 and its construction method. The technical solution is as follows: an inclined base keel 11 is set between the floor beams 10 of two adjacent floors. In order to enhance the connection strength between the base keel 11 and the floor beam 10, a reinforcing rod 12 is fixedly connected between the base keel 11 and the floor beam 10. Multiple connecting truss structures 13 are fixedly provided on the side of the base keel 11 away from the wall. Then, secondary keels 14 are connected on the connecting truss structures 13. Curtain wall units are connected between the multiple secondary keels 14 through hangers. By adopting this solution, a curved curtain wall can be obtained.

[0005] Although this type of curved curtain wall has a unique shape, the curtain walls are fixedly connected to the secondary keel 14 by hangers. When the glass curtain wall is subjected to temperature changes, it will experience thermal expansion and contraction. This will cause varying degrees of damage to the glass curtain wall, thus affecting its use.

[0006] Therefore, this problem urgently needs to be solved. Summary of the Invention

[0007] To address the aforementioned technical problems, the present invention aims to provide a construction and processing method for a steel frame structure used in curved curtain wall designs, thereby solving the technical problem that, after the existing curtain wall is installed, the spacing of the installation frame cannot be adaptively adjusted with the deformation of the curtain wall.

[0008] First aspect

[0009] To achieve the above objectives, the present invention provides a construction method for a steel frame structure for curved curtain wall designs, comprising the following steps:

[0010] S1: Installation of crossbeams: A clamping plate structure is pre-embedded in the outer wall, and multiple crossbeams are installed in the clamping plate structure, with the multiple crossbeams arranged in parallel.

[0011] S2: Installation of longitudinal beams: Multiple parallel longitudinal beams are fixedly installed on each of the transverse beams;

[0012] S3: Installation of vertical beams: Vertical beams are installed between adjacent vertical beams at different heights using connectors. After installation, the vertical beams are in a bent state. Mounting components for installing curtain walls are fixed on the outer surfaces of adjacent vertical beams at the same height. When the curtain wall is installed on the mounting components, the curtain wall can move relative to the mounting components.

[0013] By adopting the above technical solution, the normal use of the curtain wall can be ensured even when it deforms due to temperature changes. The horizontal beams provide mounting points for the vertical beams, and the vertical beams are fixed to the horizontal beams via the vertical beams. Therefore, it can be understood that the vertical beams are also installed on the horizontal beams, and the mounting components are fixedly connected to the vertical beams. When the curtain wall is installed on the mounting components, it can slide on them. Therefore, when the curtain wall deforms due to temperature changes, the deformed curtain wall will move on the mounting components, ensuring that the curtain wall is not damaged due to deformation. Furthermore, the vertical beams are designed with a curved shape, allowing the curtain wall to present a curved design during installation.

[0014] As a further description of the above technical solution, when performing step S1, the plurality of the crossbeams are slidably installed in the clamping structure.

[0015] By adopting the above technical solution, the goal of ensuring a stable connection between the beams and the cladding structure can be achieved even when the beams are affected by temperature. After actual construction, not only will the curtain wall experience thermal expansion and contraction under high or low temperatures, but the steel beam structure will also experience thermal expansion and contraction. In the steel beam structure, the beams serve as the foundation for the connection between the steel beam structure and the exterior wall. If the steel beams are fixedly connected to the embedded cladding structure, deformation of the steel beam structure can cause the beams to detach from the cladding structure, potentially leading to a cracking of the steel beam structure and the curtain wall structure, resulting in a safety accident. To solve this technical problem, the beams are slidably installed within the cladding structure. This ensures that when the beam structure deforms due to temperature, it remains stably connected to the cladding structure, thus guaranteeing the overall stability of the steel beam structure.

[0016] As a further description of the above technical solution, before executing step S1, step S0 is executed, wherein S0 includes:

[0017] S01: Install the load-bearing steel frame structure: Perform steps S1-S3 sequentially between two adjacent floors. In step S3, vertical beams are fixedly installed between adjacent longitudinal beams at different heights using supports.

[0018] S02: Install the seismic steel frame structure: Perform steps S1-S3 at the top and bottom of the load-bearing steel frame structure respectively. In step S3, vertical beams are slidably installed between adjacent longitudinal beams at different heights along the height direction of the outer wall through connecting plates.

[0019] By adopting the above technical solution, the steel frame structure can achieve seismic resistance after installation. By sliding the vertical beams onto the longitudinal beams, the vertical beams can move along the height of the exterior wall. During an earthquake, the vertical beams can move up and down along the longitudinal beams, thus offsetting the energy of the seismic source. However, if the overall load-bearing point of the steel frame structure is at the ground surface, the steel frame structure itself is not stable enough and is prone to collapse. By first installing the load-bearing steel frame structure, which is then positioned between two floors through actual construction calculations, and then installing seismic-resistant steel frame structures on the upper and lower horizontal beams of the load-bearing steel frame structure, the overall steel beam structure becomes more stable and also possesses seismic resistance.

[0020] As a further description of the above technical solution, before performing step S0, steps S01-S02 are trial-assembled in the factory to ensure that steps S01-S02 can be performed as expected when they are performed on the exterior wall of the building.

[0021] By adopting the above technical solution, the normal progress of curtain wall construction can be achieved. In building construction, since the product of this application is used to install curved curtain walls, the forming of curved curtain walls requires ensuring the installation position accuracy of each longitudinal and vertical beam. If the position accuracy is insufficient, situations may arise where the curtain wall cannot be installed on the vertical beams during actual installation, or the curtain wall can be installed on the vertical beams, but the shape of the formed curtain wall is not the expected shape. In this application's solution, by simulating the installation of the steel frame structure of the curved curtain wall in the factory, problems that may occur in actual construction can be identified, and solutions to the influencing factors can be proposed. Ultimately, this ensures that the curved curtain wall can be installed normally according to the expected design shape during actual construction.

[0022] As a further description of the above technical solution, the vertical beam in step S3 adopts a truss structure design, the vertical beam includes a first vertical beam, a second vertical beam and multiple connecting rods; wherein the first vertical beam and the second vertical beam are fixedly connected by multiple connecting rods to form a truss structure.

[0023] By adopting the above technical solutions, the stability of the curtain wall can be enhanced. Since the curtain wall is installed on vertical beams, the strength of the vertical beams is crucial; otherwise, they cannot support the curtain wall. By using a truss structure design for the vertical beams, the overall strength of the beams can be increased, enabling them to support heavier curtain walls. Furthermore, because the curtain wall has a curved shape, it also exerts shear force on the vertical beams. The truss structure design of the vertical beams provides shear resistance, further enhancing the stability of the curtain wall when installed on the vertical beams.

[0024] As a further description of the above technical solution, the vertical beam also includes an installation block and an installation bracket. The first vertical beam is located between the outer wall and the second vertical beam. An installation block for installing the curtain wall is fixedly provided on the first vertical beam, and the curtain wall is slidably installed on the installation block. An installation bracket for installing decorative panels is fixedly provided on the second vertical beam.

[0025] By adopting the above technical solutions, the aesthetic appeal of the hotel or shopping mall's exterior design can be achieved. While using a truss structure for the vertical beams enhances the overall stability of the vertical beam structure, the overall aesthetics of the shopping mall or hotel must be considered. If the second vertical beam is not treated, it will be exposed on the exterior, negatively impacting the visual effect. To solve this technical problem, decorative panels are used to cover the second vertical beam, thus concealing it and resulting in a more upscale and sophisticated appearance for the hotel or shopping mall.

[0026] As a further description of the above technical solution, when performing step S01, a load-bearing frame is erected at the construction site to support the longitudinal beam in step S2 of step S01.

[0027] By adopting the above technical solution, the land area required for construction can be saved. Traditionally, when constructing a load-bearing steel frame structure, a scaffold is erected as an operating platform to complete the construction. However, this method, once the scaffold is fully erected, obstructs the vehicle route and hinders the subsequent transportation and installation of the curtain wall. To solve this problem, a load-bearing frame is erected to support the ends of the longitudinal beams, with a vehicle passageway provided beneath the beams. This saves construction space and ensures that the concrete pump truck and curtain wall transportation are not affected.

[0028] As a further description of the above technical solution, when performing step S01, the method of hoisting the vertical beam is to first install the upper end of the vertical beam and then install the lower end of the vertical beam.

[0029] By adopting the above technical solution, the stable installation of the vertical beam can be ensured. Because the vertical beam is curved, meaning it has a certain curvature, when installing the vertical beam, if the bottom is fixed first, the top of the beam will collide with the longitudinal beam before entering its mounting section, preventing it from being properly installed. However, if the top of the vertical beam is fixed first, the bottom can then enter the mounting section, thus ensuring stable installation.

[0030] Second aspect

[0031] This invention provides a processing method for a steel frame structure for curved curtain wall designs. When producing the vertical beams in the steel frame structure for curved curtain wall designs as described in the first aspect, the vertical beams are assisted by hot bending to adjust the bending accuracy of the vertical beams.

[0032] By adopting the above technical solution, the straightness accuracy and bending camber of the vertical beam can be maintained after processing. In this application, the vertical beam used is a 19-meter bent steel beam with a bending camber of 600mm. Due to limitations in equipment bending dimensions and the difficulty of cold bending, the straightness accuracy of the bent 19-meter vertical steel beam was poor, and the bending camber did not meet the requirements. To solve this technical problem, the processing method was readjusted, and hot bending was used to assist in adjusting the bending accuracy of the vertical steel frame. The actual product processing quality met the design requirements.

[0033] As a further description of the above technical solution, when producing the support in step S01, the support includes a top seat and a base seat, which can be plugged into each other. After the top seat and the base seat are installed, an installation gap is reserved between the top seat and the base seat.

[0034] By adopting the above technical solution, the vertical beam can be stably installed. During installation, the top seat is installed on the longitudinal beam, and the base is installed on the vertical beam. The base is inserted into the top seat, and the top seat and base are fixed by bolts. The vertical beam is moved by hoisting. If the gap between the top seat and the base is small, it will be difficult for the base to be inserted into the top seat during hoisting, meaning the base will constantly collide with the top seat, thus affecting the installation of the vertical beam.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. The curtain wall can be slidably installed on the mounting components, thus adapting to the deformation of the curtain wall due to temperature changes without affecting its normal use;

[0037] 2. The crossbeam can be slidably mounted on the clamping structure, so that even if the crossbeam deforms due to temperature changes, it will still be stably fixed on the clamping structure.

[0038] 3. By decomposing the steel frame structure into a load-bearing steel frame structure and a seismic-resistant steel frame structure, the overall stability of the steel frame structure can be improved. In addition, the vertical beams in the seismic-resistant steel frame structure can move up and down, thereby achieving the effect of seismic resistance. Attached Figure Description

Detailed Implementation

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] First aspect

[0056] This invention provides a steel frame structure for curved curtain wall designs. Please refer to [link / reference]. Figure 2 and Figure 3 As shown, this includes: load-bearing steel frame structures (structures between 1F and 2F) and earthquake-resistant steel frame structures (structures below 1F and above 2F). Among them:

[0057] The load-bearing steel frame structure serves as the load-bearing beams to support the weight of the seismic-resistant steel frame structure itself. It includes multiple horizontal beams 20, multiple longitudinal beams 23, multiple supports 251, and multiple vertical beams 24. Among them:

[0058] Crossbeam 20, please refer to Figure 2 and Figure 4As shown, this serves to provide mounting support. The crossbeam 20 is a hollow rectangular steel beam, with multiple sliding slots 201 on its upper and lower surfaces. Multiple crossbeams 20 are installed parallel to each other on the outer wall 21, which has a pre-embedded clamping structure 22. The crossbeams 20 are inserted into the clamping structure 22 and fixedly connected to it using bolts and nuts. This allows the crossbeams 20 to move left and right relative to the clamping structure 22, providing a certain amount of room for contraction when the crossbeams 20 deform due to temperature changes, ultimately ensuring the stability of the fixed connection between the crossbeams 20 and the clamping structure 22.

[0059] Longitudinal beam 23, please refer to Figure 2 As shown, hollow rectangular steel beams are also used, and multiple longitudinal beams 23 are welded to the upper surface of each crossbeam 20.

[0060] Support 251, please refer to Figure 5 and 6 As shown, a connecting member 25 serves as an intermediate connector between the longitudinal beam 23 and the vertical beam 24. It includes a top seat 2511 and a base 2512. The top seat 2511 includes a base plate 25111, two vertical plates 25112, and reinforcing ribs 25113. The two vertical plates 25112 are fixedly mounted parallel to each other on the base plate 25111, forming an insertion gap 25114 between them. The reinforcing ribs 25113 are fixedly connected to the outermost parts of the base plate 25111 and the vertical plates 25112, respectively. Multiple reinforcing ribs 25113 are arranged parallel to each other on the same side, forming an installation gap 25115. The base plate 25111 of the top seat 2511 is welded to the longitudinal beam 23. The base 2512 includes a base 25121, a fixing block 25122, and reinforcing plates 25123. The fixing block 25122 is fixedly mounted on the base 25121, and the reinforcing plate 25123 is fixedly mounted on the base 25121 and the fixing block 25122. The base 25121 is welded to the vertical beam 24. The connection between the top seat 2511 and the base 2512 is as follows: the fixing block 25122 is inserted into the insertion gap 25114, and the bolts pass through the installation gap 25115, the vertical plate 25112, the fixing block 25122, and another vertical plate 25112 in sequence to achieve a fixed connection between the top seat 2511 and the base 2512.

[0061] Vertical beam 24, please refer to Figure 2 and 6As shown, this is a component used for installing the curtain wall 26. To enhance the overall strength of the vertical beam 24, the vertical beam 24 adopts a truss structure design. It includes a first vertical beam 241, a second vertical beam 242, and a connecting rod 243. The base 25121 of the base 2512 is welded to both ends of the first vertical beam 241 and both ends of the second vertical beam 242. Both the first vertical beam 241 and the second vertical beam 242 are inclined. The first vertical beam 241 is close to the exterior wall 21. A curtain wall 26 is installed between adjacent vertical beams on the same floor of the exterior wall 21. Connecting rods 243 connect the first vertical beam 241 and the second vertical beam 242. Multiple connecting rods 243 form a truss structure. To hide the second vertical beam 242, a mounting bracket 281 can be installed on the second vertical beam 242. Decorative panels 27 are connected to the mounting bracket 281 to hide the second vertical beam 242, thereby making the surface of the exterior wall 21 more aesthetically pleasing. The rendering of the completed hotel or shopping mall is shown below. Figure 7 As shown. Secondly, in order to ensure that the curtain wall 26 can be stably installed on the first vertical beam 241 even after deformation due to temperature changes, an installation block 282 is welded onto the first vertical beam 241, and an installation slot 2821 is provided on the installation block 282. Please refer to... Figure 2 As shown, when the curtain wall 26 is installed on the mounting slot 2821, the curtain wall 26 can slide left and right on the mounting block 282. That is, when the curtain wall 26 deforms due to temperature changes, the curtain wall 26 can still be stably fixed on the mounting block 282.

[0062] For earthquake-resistant steel beam structures, please refer to [link / reference]. Figure 2 and Figure 3 As shown, this design enables the steel beam structure itself to have seismic resistance. The design of seismic-resistant steel beam structures above 2F is the same as that of load-bearing steel beam structures, the only difference being the connection method between longitudinal beams 23 and vertical beams 24. In the load-bearing horizontal beam 20 structure, the connection between longitudinal beams 23 and vertical beams 24 is fixed through supports 251; however, in the seismic-resistant steel beam structure, please refer to... Figure 8 As shown, the longitudinal beams 23 and vertical beams 24 in the seismic-resistant steel beam structure are fixedly connected by connecting plates 252. Connecting plates 252 are welded to the left and right outer surfaces of the longitudinal beams 23, and multiple connecting slots 2521 are provided on the connecting plates 252. A vertical beam 24 is positioned between two connecting plates 252, and bolts pass through the two connecting plates 252 and the vertical beam 24, thus fixing the vertical beam 24 to the longitudinal beam 23. Because the vertical beam 24 can move up and down relative to the longitudinal beam 23, the seismic-resistant steel beam structure above 2F has a certain seismic resistance function. Please refer to [reference needed] in this application. Figure 2 and Figure 9As shown, the seismic-resistant steel beam structure below 1 floor is the same as that above 2 floors. The difference lies in the fact that, in the seismic-resistant steel beam structure below 1 floor, the vertical beam 24 is not easily fixed to the embedded parts on the ground due to its curved design. In this embodiment, the vertical beam 24 connected to the embedded parts on the ground is further improved by fixing a vertical beam 29A at the bottom of the vertical beam 24. A connecting slot 2521 is also provided on the vertical beam 29A. This ensures that the seismic-resistant steel beam structure below 1 floor has the function of vertical movement, thereby enabling it to have a certain seismic resistance. Finally, please refer to... Figure 3 and Figure 8 As shown, the transition connection between the seismic steel beam structure and the load-bearing steel beam structure is as follows: a support 251 is installed on the upper part of the longitudinal beam 23 at 1F, a connecting plate 252 is installed on the side surface of the longitudinal beam 23 at 1F, a support 251 is installed at the bottom of the longitudinal beam 23 at 2F, and a connecting plate 252 is installed on the side surface of the longitudinal beam 23 at 2F.

[0063] Finally, it should be emphasized that in this application, since it is calculated that the area between 1F and 2F serves as a load-bearing steel beam structure to support the weight of the two seismic-resistant steel beam structures, in other embodiments, if it is calculated during the decoration process that other floors serve as load-bearing steel beam structures, these can also be understood as being within the scope of protection of this application; or, if due to decoration needs, only load-bearing steel beam structures or only seismic-resistant steel beam structures are installed on the exterior wall 21, these can also be considered as being within the scope of protection of this application.

[0064] The working principle of this invention is described below:

[0065] In this embodiment, the horizontal beam 20 serves as an installation support point for the vertical beam 23, and the vertical beam 24 is fixedly installed on the horizontal beam 20 through the vertical beam 23. Therefore, it can be understood that the vertical beam 24 is also installed on the horizontal beam 20, and the mounting component 28 is fixedly connected to the vertical beam 24. When the curtain wall 26 is installed on the mounting component 28, since the curtain wall 26 can slide on the mounting component 28, when the curtain wall 26 deforms due to temperature changes, the deformed curtain wall 26 will move on the mounting component 28, thereby ensuring that the curtain wall 26 will not be damaged due to deformation. The vertical beam 24 is also designed in a curved shape, so that the curtain wall 26 can also present a curved surface design during installation. Furthermore, since the vertical beam 24 serves as the load-bearing beam of the curtain wall 26, its overall strength is enhanced by adopting a truss structure design, thus enabling it to support the heavier curtain wall 26. In addition, because the curtain wall 26 has a curved shape, it also exerts shear force on the vertical beam 24. The truss structure of the vertical beam 24 also has shear resistance, making the curtain wall 26 more stable when installed on the vertical beam 24. Moreover, to ensure the overall aesthetics of the hotel or shopping mall, the truss structure of the vertical beam 24 is wrapped with decorative panels 27, making the hotel or shopping mall's exterior structure more high-end and grand.

[0066] Second aspect

[0067] The present invention also discloses a processing method for a steel frame structure for curved curtain wall design, specifically for producing the support 251 and vertical beam 24 in the first aspect.

[0068] Please see Figure 4As shown, support 251: In order to facilitate the insertion of the top seat 2511 and the base 2512 in support 251, the insertion gap 25114 of the top seat 2511 can be designed to be larger and the fixing block 25122 of the base 2512 can be designed to be smaller during the production of support 251. This way, when the fixing block 25122 is inserted into the insertion gap 25114 and the top seat 2511 and the base 2512 are fixed with bolts, there is a certain gap between the fixing block 25122 and the inner wall of the insertion gap 25114. This can prevent the base 2512 from being difficult to insert into the top seat 2511 during the hoisting of the vertical beam 24 and prevent the base 2512 from constantly colliding with the top seat 2511. Secondly, since the vertical beam 24 is a load-bearing beam during the installation of the curtain wall 26, the bolt connection between the base 2512 and the top seat 2511 requires a certain strength from the bolts. In practical use, thicker bolts are obviously better. If the plates in the top seat 2511 and the base 2512 are fixedly connected by welding, the weld will occupy a certain space for the bolts, thus affecting the bolt's movement when passing through the threaded holes. To solve this problem, the plates are fixedly connected by full penetration groove welding, so that the bolt is not affected by the weld when moving forward.

[0069] Vertical Beam 24: To ensure the straightness and curvature of the vertical beam 24 after production, the processing method was readjusted during manufacturing. Hot bending was used to assist in adjusting the bending accuracy of the vertical steel frame, and the actual product processing quality met the design requirements. To accelerate the on-site installation efficiency of the curtain wall 26, the mounting bracket 281 was pre-welded to the vertical beam 24 in the factory, thereby reducing the on-site welding process of the mounting bracket 281 and thus accelerating the installation efficiency of the curtain wall 26.

[0070] Third aspect

[0071] This invention discloses a construction method for a steel frame structure used in curved curtain wall designs, comprising the following steps:

[0072] S01: Install the load-bearing steel frame structure:

[0073] S011: A clamping plate structure 22 is pre-embedded in the two adjacent floors of the exterior wall 21, and multiple beams 20 are fixedly installed in the clamping plate structure 22, so that the multiple beams 20 are arranged in parallel on the exterior wall 21.

[0074] S012: Installation of longitudinal beams 23: Multiple parallel longitudinal beams 23 are installed on each crossbeam 20, and the multiple longitudinal beams 23 on a crossbeam 20 can slide relative to each other.

[0075] S013: Installation of vertical beam 24: During step S3, vertical beam 24 is fixedly installed between adjacent vertical beams 23 at different heights by means of connector 25. After the vertical beam 24 is installed, it is in a bent state. In addition, there is an installation space for installing curtain wall 26 between adjacent vertical beams 24 at the same height.

After the vertical beam 24 is installed, it is in a bent state. In addition, there is an installation space for installing curtain wall 26 between adjacent vertical beams 24 at the same height.

[0080] S03: Install the seismic-resistant steel frame structure below:

[0081] S031: A clamping plate structure 22 is pre-embedded in the upper outer wall 21 of the load-bearing steel frame structure, and multiple beams 20 are fixedly installed in the clamping plate structure 22, so that the multiple beams 20 are arranged in parallel on the outer wall 21.

[0082] S032: Installation of longitudinal beams 23: Multiple parallel longitudinal beams 23 are installed on each crossbeam 20, and the multiple longitudinal beams 23 on a crossbeam 20 can slide relative to each other.

[0083] S033: Installation of vertical beam 24: Vertical beam 24 is slidably installed between adjacent vertical beams 23 at different heights along the height direction of the outer wall 21 via connector 25. After the vertical beam 24 is installed, the vertical beam 24 is in a bent state. In addition, there is an installation space for installing curtain wall 26 between adjacent vertical beams 24 at the same height.

[0084] S03: Closure of seismic-resistant steel frame structures and load-bearing steel frame structures:

[0085] S031: Closure of the upper seismic steel frame structure: Fix the connecting plate 252 on the upper horizontal beam 20 of the load-bearing steel frame structure, and install the lower vertical beam 24 of the upper seismic steel frame structure on the upper horizontal beam 20 of the load-bearing steel frame structure through the connecting plate 252.

[0086] S032: Closure of the lower seismic steel frame structure: Fix the connecting plate 252 on the lower horizontal beam 20 of the load-bearing steel frame structure, and install the upper vertical beam 24 of the lower seismic steel frame structure on the lower horizontal beam 20 of the load-bearing steel frame structure through the connecting plate 252.

[0087] To ensure the smooth installation of the curtain wall 26 during construction, the steel frame structure was first trial-assembled in the factory before construction. By simulating the installation of the curved curtain wall 26's steel frame structure in the factory, problems that might arise during actual construction could be identified, and solutions could be proposed. Ultimately, this ensures that the curved curtain wall 26 can be installed normally according to the expected design shape during actual construction.

[0088] Please see Figure 3 As shown, after the trial assembly was completed in the factory, the overall stress analysis of the steel frame structure revealed that the longitudinal beams 23 on floors 2F, 4F, 5F, 6F, 7F, and 8F are fixed vertical stress nodes; GF (ground floor), 1F, and 3F are vertical release nodes. Among them, the longitudinal beam 23 on floor 2F is the main stress location of the entire steel frame structure system and the primary key point in the installation sequence. Therefore, in the actual construction of the steel frame, the steel frame structure on floor 2F should be built first, then the steel frame structure above floor 2F should be built, and finally the steel frame structure below floor 2F should be built. In this way, the steel frame structure of the exterior wall 21 can be stably built.

[0089] Please see Figure 10 As shown, during the construction process, the traditional method for erecting the steel frame structure on the first floor involves building a scaffold as an operating platform to complete the construction. However, this method, once the scaffold is fully erected, will block the vehicle route and hinder the subsequent transportation and installation of the curtain wall 26. To solve this problem, a load-bearing frame 29 is erected to support the ends of the longitudinal beams 23, with a vehicle passageway provided below the longitudinal beams 23. This saves construction space and ensures that the transportation of concrete pump trucks and curtain wall 26 is not affected.

[0090] Since the vertical beam 24 is curved, that is, the vertical beam 24 has a certain curvature, please refer to [link / reference needed]. Figure 11As shown, when installing the vertical beam 24, the bottom of the vertical beam 24 is fixed first. When installing the top of the vertical beam 24, the top of the vertical beam 24 will collide with the longitudinal beam 23 before entering the mounting part of the longitudinal beam 23. That is, the vertical beam 24 cannot enter the mounting part of the longitudinal beam 23. At this time, the fixed installation of the vertical beam 24 cannot be achieved. Please refer to [link / reference]. Figure 12 As shown, when the vertical beam 24 is fixedly installed at the top first, the bottom of the vertical beam 24 can enter the installation part of the longitudinal beam 23, thus ensuring the stable installation of the vertical beam 24.

[0091] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
