Description

Technical Field

[0001] This application relates to the field of building curtain walls, and in particular to a construction process for a semi-unit aluminum panel curtain wall. Background Technology

[0002] A curtain wall is the exterior wall cladding of a building. It does not bear the load of the main structure and is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings.

[0003] Currently, the installation of conventional metal panel curtain walls requires first welding the supporting frame to the building facade, and then installing the metal panels onto the supporting frame. The supporting frame is composed of multiple welded steel pipes. The keel section of the steel pipes needs to be installed one by one on the building facade and then fully welded. The remaining steel pipes are then welded onto the keel steel pipes to form the supporting frame.

[0004] Conventional metal panel curtain wall installation methods involve many procedures, with numerous welding points during aerial work, posing significant safety hazards, and making it difficult to control the quality of high-altitude installations. Summary of the Invention

[0005] To address the issues of numerous installation procedures, many welding points during aerial work, significant safety hazards, and difficulty in controlling the quality of high-altitude installations in metal panel curtain walls, this application provides a construction process for a semi-unit aluminum panel curtain wall.

[0006] The construction process for a semi-unit aluminum panel curtain wall provided in this application adopts the following technical solution:

[0007] A construction process for a semi-unit aluminum panel curtain wall includes the following steps: S1: Laying out lines according to architectural drawings and on-site measurements; S2: Pre-welding connecting steel frames and main steel frames on the ground; S3: First installing adapters on the building facade, then welding the connecting steel frames onto the adapters; S4: Welding U-shaped steel components onto the connecting steel frames, and using bolt assemblies in conjunction with the U-shaped steel components to install steel columns onto the connecting steel frames; S5: First re-measuring the installation position of the steel columns, then adjusting the steel columns based on the re-measuring results; S6: Fixing the main steel frame onto the steel columns; S7: First re-measuring the installation position of the main steel frame, then adjusting the main steel frame based on the re-measuring results; S8: Installing aluminum panels on the main steel frame.

[0008] By adopting the above technical solution, when installing aluminum panel curtain walls, the supporting framework is divided into connecting steel frames, steel columns, and main steel frames. The connecting steel frames and main steel frames are pre-welded to the ground. First, the connecting steel frames are installed on the building facade. Then, the main steel frames are installed on the connecting steel frames via the steel columns. Finally, the aluminum panels are installed on the main steel frames, completing the installation of the aluminum panel curtain wall. This setup, using pre-welded connecting steel frames and main steel frames, reduces the number of installation steps, the number of welding points during aerial work, and the potential installation hazards. Furthermore, by re-measuring and adjusting the steel columns and main steel frames during installation, it is easier to control the quality of high-altitude installation.

[0009] Preferably, in step S3, embedded parts are pre-embedded in the building facade. After cleaning the surface of the embedded parts, the adapter is welded onto the embedded parts.

[0010] By adopting the above technical solution, the adapter is welded onto the embedded part, making the connecting steel frame more stable when installed on the building facade.

[0011] Preferably, in step S3, the connecting steel frame is formed by welding two transverse steel pipes and one oblique steel pipe to form a Z-shaped structure. The transverse steel pipes are welded to the adapter. Reinforcing ribs are welded to both sides of the transverse steel pipes near the adapter in the horizontal direction, and the reinforcing ribs are welded and fixed to the adapter.

[0012] By adopting the above technical solution, the Z-shaped connecting steel frame increases the structural strength of the connecting steel frame itself, and the reinforcing ribs strengthen the connecting steel frame, making it less prone to swaying in the horizontal direction, thereby further increasing the stability of the connecting steel frame.

[0013] Preferably, in step S4, sliding strip holes are provided on both opposite side walls of the U-shaped steel member in the horizontal direction, the steel column is located between the sliding strip holes on both side walls of the U-shaped steel member, the bolt assembly passes through the sliding strip holes and the steel column and fixes the steel column, and the bolt assembly is slidably installed in the sliding strip holes in the horizontal direction.

[0014] By adopting the above technical solution, the steel column is inserted into the U-shaped steel component from the open end of the U-shaped steel component, and then the bolt assembly is passed through the sliding strip hole of the U-shaped steel component and the steel column, thereby firmly installing the steel column on the connecting steel frame. The U-shaped steel component limits the steel column, so that the steel column will not deflect on the connecting steel frame.

[0015] Preferably, in step S5, the distance between the steel column and the building facade is measured. If the measured dimension is consistent with the theoretical dimension, there is no need to adjust the steel column; if the measured dimension is inconsistent with the theoretical dimension, the steel column is adjusted by sliding the bolt assembly in the sliding strip hole.

[0016] By adopting the above technical solution, when the steel column needs to be adjusted, the bolt assembly is loosened. At this time, the bolt assembly can slide in the sliding strip hole of the U-shaped steel part, so that the distance between the steel column and the building facade can be adjusted. After adjustment, the bolt assembly is rotated to fix the steel column.

[0017] Preferably, in step S6, a support member is fixedly installed on the steel column, and the support member is located below the main steel frame and supports the main steel frame.

[0018] By adopting the above technical solution, the supporting components support the main steel frame, making the main body more stable when installed on the steel columns.

[0019] Preferably, in step S7, positioning points are marked on the main steel frame, and the distance between the positioning points and the building facade, as well as the height of the positioning points, are measured. If the measured dimensions are consistent with the theoretical dimensions, there is no need to adjust the steel columns; if the distance dimensions are inconsistent with the theoretical dimensions, the steel columns are moved by sliding the bolt assembly in the sliding strip hole, and the steel columns then move the main steel frame for adjustment; if the height dimensions are inconsistent with the theoretical dimensions, the main steel frame is adjusted by adding shims to the support components.

[0020] By adopting the above technical solution, when it is necessary to adjust the distance between the main steel frame and the building facade, the bolt assembly is loosened, the position of the steel column is adjusted, and the steel column drives the main steel frame to adjust accordingly. When it is necessary to adjust the height of the main steel frame, the main steel frame is first removed from the support, then shims are welded to the support on the side of the main steel frame with the lower height, and finally the main steel frame is welded and fixed to the support, thus completing the height adjustment of the main steel frame. This design allows the main steel frame to be adjusted accordingly during installation, thereby ensuring the quality of high-altitude installation.

[0021] Preferably, in step S6, before re-measuring the installation position of the main steel frame, the main steel frame is connected to the support component by spot welding; after adjusting the main steel frame, the main steel frame is connected to the support component or shim by full welding.

[0022] By adopting the above technical solution, the main steel frame is connected by spot welding before re-measurement, which makes it easy to quickly disassemble the main steel frame and the supporting components when the height of the main steel frame needs to be adjusted.

[0023] Preferably, in step S7, after adjusting the main steel frame, the welding slag is removed and anti-rust paint is applied to the steel structural components.

[0024] By adopting the above technical solution, the anti-rust paint protects the steel structural components of the aluminum panel curtain wall from rust, thereby improving the service life of the aluminum panel curtain wall.

[0025] Preferably, in step S8, after the aluminum plates are installed, the gaps between adjacent aluminum plates are sealed with adhesive.

[0026] By adopting the above technical solution, the gaps between aluminum plates are sealed, reducing the possibility of water leakage between the aluminum plates.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By adopting the method of pre-welding the steel frame and the main steel frame, the curtain wall installation process is reduced, the number of welding points during aerial operations is reduced, and the installation risks during operations are reduced. At the same time, by re-measuring and adjusting the steel columns and the main steel frame during the installation process, it is easier to control the quality of high-altitude installation.

[0029] 2. By reinforcing the connecting steel frame with reinforcing ribs, the connecting steel frame is less likely to sway in the horizontal direction, thereby increasing the stability of the connecting steel frame;

[0030] 3. By using sliding strip holes in the U-shaped steel component, the bolt assembly can slide inside the U-shaped steel component, thereby enabling the steel column and main steel frame to be adjusted. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses a construction process for a semi-unit aluminum panel curtain wall.

[0038] Reference Figure 1 The construction process for a semi-unit aluminum panel curtain wall includes the following steps:

[0039] S1: Construction workers use tools such as theodolites, gantry boards, ropes, plumb bobs, and steel tape measures to measure and lay out lines according to the architectural drawings and site conditions.

[0040] Reference Figure 2 S2: Based on the architectural drawings and site conditions, the construction personnel first calculate the dimensions of the aluminum panel curtain wall support frame. Each floor of the building corresponds to one support frame, and each support frame is composed of multiple support modules 1 connected together. Based on the architectural drawings and site conditions, the construction personnel then calculate the dimensions of each support module 1. Each support module 1 consists of a main steel frame 12, two connecting steel frames 11, and steel columns 13. The connecting steel frames 11 and the main steel frame 12 are pre-welded at the construction site or factory.

[0041] First, use hoisting equipment to lift the connecting steel frame 11 to the designated height, and then install the two connecting steel frames 11 on the exterior facade of the building. Next, install the two steel columns 13 on the two connecting steel frames 11, and finally install the main steel frame 12 on the two steel columns 13 to complete the installation of one support module. Multiple support modules 1 of each floor's support frame are installed at intervals along the horizontal direction, and adjacent support modules 1 are connected by connecting steel pipes 10.

[0042] Reference Figure 2 and 3 S3: Each floor of the building facade has an embedded part 6. First, the position of the embedded part 6 is calibrated, and then the outer surface of the embedded part 6 is cleaned. In this application, the embedded part 6 is composed of a steel plate and six steel bars welded together. The steel plate and steel bars are embedded in the building, and the outer surface of the steel plate away from the steel bars is located on the building facade.

[0043] First, install the adapter 3 on the outer surface of the embedded part 6. The adapter 3 can be made of channel steel. The vertical cross section of the adapter 3 is C-shaped. The opening of the C-shaped cross section of the adapter 3 points to the embedded part 6, and both ends of the adapter 3 are welded and fixed to the embedded part 6.

[0044] The connecting steel frame 11 is then welded to the side wall of the adapter 3 away from the embedded part 6, with one connecting steel frame 11 corresponding to two adapters 3. The connecting steel frame 11 is composed of two horizontal steel pipes 111 and one oblique steel pipe 112 welded together. The two horizontal steel pipes 111 are welded and fixed to the two adapters 3 in the horizontal direction. The two horizontal steel pipes 111 are arranged at intervals in the vertical direction. The oblique steel pipe 112 is located between the two horizontal steel pipes 111, and the two ends of the oblique steel pipe 112 are welded and fixed to the ends of the two horizontal steel pipes 111 that are far apart from each other, forming a Z-shaped connecting steel frame 11. The end of the horizontal steel pipe 111 near the adapter 3 is symmetrically welded with reinforcing ribs 7 in the horizontal direction, and the reinforcing ribs 7 are welded and fixed to the adapter 3. In this application, the reinforcing ribs 7 can be made of steel plate. The Z-shaped connecting steel frame 11, together with the reinforcing ribs 7, makes the connecting steel frame 11 more stable when installed on the adapter 3.

[0045] S4: A U-shaped steel member 4 is welded and fixed at the end of the transverse steel pipe 111 away from the adapter 3. In this application, the U-shaped steel member 4 can be made of channel steel. The horizontal cross section of the U-shaped steel member 4 is C-shaped, and the opening of the C-shaped cross section of the U-shaped steel member 4 points away from the transverse steel pipe 111. Two sliding strip holes 8 are opened on the opposite side walls of the U-shaped steel member 4. The sliding strip holes 8 are opened in the horizontal direction, and the two sliding strip holes 8 are opened at intervals in the vertical direction.

[0046] A steel column 13 is installed inside two U-shaped steel parts 4 of a connecting steel frame 11. The steel column 13 is fixedly installed inside the two U-shaped steel parts 4 using four bolt assemblies 5. The bolt assembly 5 includes bolts and nuts. Connecting plates 14 are provided on both sides of a U-shaped steel part 4 in the horizontal direction. The bolts slide through the connecting plates 14, the sliding strip holes 8 and the steel column 13. The nuts are sleeved on the ends of the bolts and abut against the connecting plates 14, thereby fixing the steel column 13.

[0047] S5: After the steel column 13 is installed, the distance between the steel column 13 and the building facade is measured. If the measured size matches the theoretical size or is within a reasonable error range, the next step of construction is continued. If the measured size exceeds the reasonable error range, the steel column 13 is adjusted.

[0048] The inner depth of the U-shaped steel component 4 is greater than the thickness of the steel column 13, and there is a sliding space between the side wall of the steel column 13 and the bottom wall of the inner cavity of the U-shaped steel component 4 for the steel column 13 to slide. By rotating the four bolt assemblies 5 on one of the steel columns 13, the bolt assemblies 5 are loosened, and the bolts can slide within the sliding slots 8 of the U-shaped steel component 4, thereby allowing the steel column 13 to slide within the U-shaped steel component 4, thus adjusting the steel column 13.

[0049] S6: Two support members 9 are welded and fixed at intervals on the side wall of a steel column 13 away from the connecting steel frame 11. In this application, the support members 9 can be made of angle steel. A main steel frame 12 is placed on the four support members 9, and the contact surfaces of the main steel frame 12, the steel column 13, and the support members 9 are spot welded to complete the initial fixation of the main steel frame 12.

[0050] S7: Mark the bottom end of the main steel frame 12 near the steel column 13 as the positioning point. After the main steel frame 12 is initially fixed, measure the distance between the positioning point and the building facade, as well as the height of the positioning point. If the measured distance and height dimensions match the theoretical dimensions or are within a reasonable error range, then fully weld the contact surfaces of the main steel frame 12, the steel column 13, and the support 9, and continue to the next step of construction. If the measured distance dimension has an error exceeding the reasonable range from the theoretical dimensions, adjust the distance of the main steel frame 12. If the measured height dimension has an error exceeding the reasonable range from the theoretical dimensions, adjust the height of the main steel frame 12. If both the measured distance and height dimensions have errors exceeding the reasonable range from the theoretical dimensions, adjust both the distance and height of the main steel frame 12.

[0051] When adjusting the distance of the main steel frame 12, the eight bolt assemblies 5 on the two steel columns 13 inside a support module 1 are rotated, and the two steel columns 13 can slide, thereby driving the main steel frame 12 on the two steel columns 13 to slide, thereby adjusting the distance of the main steel frame 12.

[0052] When adjusting the height of the main steel frame 12, the main steel frame 12, steel column 13, and support member 9 are first disassembled. Since the main steel frame 12 is initially fixed by spot welding, disassembly is more convenient and quick. First, a shim is welded to the top wall of the support member 9 on the side of the main steel frame 12 with lower height. Then, the main steel frame 12 is installed on the support member 9 and the shim, thereby adjusting the height of the main steel frame 12.

[0053] After the main steel frame 12 is adjusted, the connections between the main steel frame 12 and the steel columns 13, the support components 9, and the shims are first fully welded and fixed. Then, the weld slag is removed, and anti-rust paint is applied to the adapter 3, connecting steel frame 11, reinforcing ribs 7, support components 9, steel columns 13, and main steel frame 12. In this application, the adapter 3, connecting steel frame 11, reinforcing ribs 7, support components 9, steel columns 13, and main steel frame 12 are all hot-dip galvanized. The galvanized layer and anti-rust paint protect the steel structural components of the aluminum panel curtain wall, thereby improving the service life of the aluminum panel curtain wall.

[0054] Reference Figure 2 and 3S8: Connecting steel pipes 10 are used to connect two adjacent support modules 1 to enhance the stability of the support module 1. The two ends of the connecting steel pipes 10 are welded and fixed to the steel columns 13 of the two support modules 1 that are close to each other. There are two connecting steel pipes 10, and the two connecting steel pipes 10 are arranged at intervals in the vertical direction.

[0055] Aluminum plates are installed on the main steel frame 12. First, the gaps between the aluminum plates are sealed with adhesive, and then the sealed areas are cleaned. Sealing the gaps between the aluminum plates reduces the possibility of water leakage.

[0056] The installation of the aluminum panel curtain wall can be completed by following the above steps.

[0057] The implementation principle of this application embodiment is as follows: When installing the aluminum panel curtain wall, the supporting frame of the aluminum panel curtain wall is divided into a connecting steel frame 11, steel columns 13, and a main steel frame 12. The connecting steel frame 11 and the main steel frame 12 are pre-welded on the ground. First, the connecting steel frame 11 is installed on the exterior facade of the building. Then, the main steel frame 12 is installed on the connecting steel frame 11 through the steel columns 13. Finally, the aluminum panels are installed on the main steel frame 12, thus completing the installation of the aluminum panel curtain wall. By pre-welding the connecting steel frame 11 and the main steel frame 12, the curtain wall installation process is reduced, the number of welding points during aerial operations is reduced, and the installation hazards during operations are decreased. At the same time, by re-measuring and adjusting the steel columns 13 and the main steel frame 12 during the installation process, it is easier to control the quality of high-altitude installation.

[0058] 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.
