[0002] The power dispatch and control center is the core organizational unit of the power system, responsible for the operation, dispatch, control, and management of the power system. To meet the requirements for fire prevention, anti-static properties, and high-temperature resistance, the power dispatch and control center must possess specialized dispatch centers and related facilities that comply with national standards and regulations. Typically, for fire prevention, anti-static properties, and high-temperature resistance, the dispatch center is housed in enclosed rooms, with thickened ceiling structures or the installation of fire-resistant, anti-static, high-temperature-resistant, and sound-insulating materials.

[0003] For ceilings requiring curved shapes, conventional aluminum panel ceilings have the problem of simple structure and insufficient aesthetics, failing to meet the requirements of curved shapes; while traditional curved wooden base or steel structure curved veneer have the problem of large weight and thickness, resulting in a reduction of usable area in functional rooms, and also have the problem of complex installation procedures and high installation costs.

[0005] To achieve the above objectives, the present invention provides a large-area arc-shaped painted aluminum panel ceiling structure, comprising:

[0006] A steel frame structure transfer layer is fixedly installed on the structural floor slab. A painted aluminum plate surface layer is fixedly installed on one side of the steel frame structure transfer layer relative to the structural floor slab. The painted aluminum plate surface layer includes multiple arc-shaped painted aluminum plate units arranged along the length direction of the structural floor slab. The multiple arc-shaped painted aluminum plate units are interconnected, and a fiber sound-absorbing mesh cloth is fixedly installed on the side close to the steel frame structure transfer layer.

[0007] Preferably, a steel frame embedded part is fixedly installed on the structural floor slab. The steel frame embedded part and the structural floor slab are respectively provided with holes. A screw for fixing the steel frame embedded part to the structural floor slab is inserted into the hole. The steel frame structural transfer layer is fixedly installed on the side of the steel frame embedded part opposite to the structural floor slab.

[0008] Preferably, the steel frame structure transfer layer includes a first transfer rod perpendicular to the structural floor slab and fixedly connected to the steel frame embedded part, a second transfer rod vertically fixedly installed at one end of the first transfer rod along its length direction relative to the steel frame embedded part, and a plurality of hangers fixedly installed on the second transfer rod on one side relative to the first transfer rod, wherein the painted aluminum plate surface layer is fixedly installed on one end of the plurality of hangers relative to the second transfer rod.

[0009] Preferably, a hanger is fixedly installed at one end of the suspension rod near the surface of the painted aluminum plate, and multiple arc-shaped painted aluminum plate units are hung and fixed to the suspension rod through the hanger.

[0010] Preferably, a secondary keel is fixedly installed on the end of the arc-shaped painted aluminum plate unit near the hanger along the length direction of the arc-shaped painted aluminum plate unit. On the side of the secondary keel away from the arc-shaped painted aluminum plate unit, a plurality of main keels are fixedly installed along the length direction of the secondary keel corresponding to the hanger rod. The plurality of main keels are perpendicular to the secondary keel, and the side of the plurality of main keels near the hanger rod forms a fixing groove for locking and fixing the hanger.

[0011] Preferably, the curved painted aluminum panel unit includes a suspended ceiling along the length of the structural floor slab and a splicing part that is vertically fixed to the suspended ceiling and for connecting adjacent curved painted aluminum panel units. One end of the suspended ceiling and the splicing part are connected to each other and extend outward relative to the splicing part along the length of the structural floor slab.

[0012] Preferably, a connecting keel is fixedly installed on the second conversion rod parallel to the suspension rod, and the connecting keel is fixedly connected to the splicing part and the ceiling of the adjacent arc-shaped painted aluminum plate unit on one side relative to the second conversion rod.

[0013] Preferably, a connecting rod is also fixedly installed on the second conversion rod parallel to the suspension rod, and a special hook is fixedly installed on the end of the connecting rod away from the second conversion rod for fixing and connecting one end of the splicing part of the ceiling near the adjacent arc-shaped painted aluminum plate unit.

[0014] A construction method for a large-area curved painted aluminum panel ceiling structure, the method comprising the following steps:

[0015] Based on the building axis, the decorative axis line is marked on the structural floor slab, and the finished decorative line is marked along the perimeter of the wall according to the decorative axis line.

[0016] A steel frame structure transfer layer is fixedly installed on the structural floor slab, and a keel is installed on the side of the steel frame structure transfer layer opposite to the structural floor slab.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects:

[0020] 1) Compared to traditional curved wooden baseboards or curved steel structure finishes, this large-area curved painted aluminum panel ceiling structure has a smaller weight and thickness. Its weight is only 15%-20% of that of wood panels, which reduces structural load and lowers the investment in the main structure. At the same time, the reduced thickness significantly increases the usable area of ​​functional rooms.

[0021] 2) The ceiling components are manufactured in a standardized factory and installed quickly on site, which shortens the construction period.

[0022] 3) The thickness of the aluminum plate can be adjusted according to the actual fireproof and high temperature resistance requirements, and it can be assembled with seams to enhance the surface decoration effect.

[0023] 4) Reduced on-site welding operations and lowered the level of on-site construction pollution. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The technical problem this invention aims to solve is the ceiling design for power dispatch centers. These centers require thickened structures or the addition of fire-resistant, anti-static, high-temperature resistant, and sound-insulating materials. When curved shapes are required, conventional aluminum panel ceilings suffer from simple structures, insufficient aesthetics, and inability to meet the requirements of curved shapes. Traditional curved wooden bases or steel curved finishes are heavy and thick, reducing the usable area of ​​functional rooms, and also involve complex installation procedures and high costs. Therefore, this invention provides a large-area curved painted aluminum panel ceiling structure and its construction method specifically designed for the fire-resistant and high-temperature resistant requirements of power control centers. This method reduces the weight of the ceiling decoration, optimizes the installation process, achieves fire resistance and high-temperature resistance, simplifies the construction process, speeds up construction, and reduces construction costs.

[0033] Please see Figure 1 and Figure 2As shown, the present invention provides a large-area arc-shaped painted aluminum panel ceiling structure, including a steel frame structure transfer layer 3 fixedly installed on the structural floor slab 1. A painted aluminum panel surface layer is fixedly installed on one side of the steel frame structure transfer layer 3 relative to the structural floor slab 1. The painted aluminum panel surface layer includes a plurality of arc-shaped painted aluminum panel units 4 arranged along the length direction of the structural floor slab 1. The plurality of arc-shaped painted aluminum panel units 4 are interconnected, and a fiber sound-absorbing mesh cloth 5 is fixedly installed on the side close to the steel frame structure transfer layer 3. It should be noted that in this embodiment, the structural floor slab 1 is a concrete floor slab, and the curved painted aluminum plate 4 unit can be customized according to design requirements. The standard sizes (length × width) are: 1300mm×4000mm, 1500mm×4000mm, 1800mm×4000mm, 2400mm×1200mm, 2600mm×800mm, 2600mm×1200mm, 2700mm×1600mm, 3200mm×1600mm, 3600mm×1600mm, etc., and the thicknesses are 1.5mm, 2.0mm, 3.0mm, 3.5mm, 4.0mm, 5mm, etc. The fiber sound-absorbing mesh cloth 5 can be directly pasted to the back of the painted aluminum plate with special structural adhesive during factory processing. Compared with the construction of reinstalling sound-absorbing cotton, it saves a process. At the same time, the fiber sound-absorbing mesh cloth and the painted aluminum plate are integrated into one, which greatly reduces the risk of spontaneous combustion of the painted aluminum plate. More preferably, such as Figure 2 As shown, in order to ensure tight seams and prevent the spread of fire and smoke, the seams of the fiber sound-absorbing mesh fabric 5 are installed with staggered seams and covered with seams. The fiber sound-absorbing mesh fabric 5 is specially treated with fireproof materials, which can effectively prevent smoke and fire.

[0034] Please see Figures 1 to 4 As shown, a steel frame embedded part 2 is fixedly installed on the structural floor slab 1. Holes are correspondingly opened on both the steel frame embedded part 2 and the structural floor slab 1. A screw rod 21 for fixing the steel frame embedded part 2 to the structural floor slab 1 is inserted into each hole. A steel frame structural transfer layer 3 is fixedly installed on one side of the steel frame embedded part 2 relative to the structural floor slab 1. Preferably, the steel frame structural transfer layer 3 includes a first transfer rod 31 perpendicular to the structural floor slab 1 and fixedly connected to the steel frame embedded part 2; a second transfer rod 31 vertically fixedly installed at one end of the first transfer rod 31 along its length relative to the steel frame embedded part 2; and multiple hangers 33 fixedly installed on the second transfer rod 32 on one side relative to the first transfer rod 21. A painted aluminum panel surface is fixedly installed at one end of the multiple hangers 33 relative to the second transfer rod 32. It should be noted that in this embodiment, both the first conversion rod 31 and the second conversion rod 32 are galvanized square steel. The second conversion rod 32 has a hole for the hanger 33 to pass through. The end of the hanger 33 near the second conversion rod 32 is inserted into the hole and fixedly installed on the second conversion rod 32 with the fixing nut 34.

[0035] Furthermore, a hanger 6 is fixedly installed at one end of the hanger 33 near the surface of the painted aluminum plate. Multiple curved painted aluminum plate units 4 are hung and fixed to the hanger 33 via the hanger 6. In this embodiment, the hanger 6 is a common auxiliary keel hanger used in the installation of aluminum plate keels. Preferably, a secondary keel 72 is fixedly installed along the length of the curved painted aluminum plate unit 4 at one end near the hanger 5. Multiple main keels 71 are fixedly installed on the side of the secondary keel 72 away from the curved painted aluminum plate unit 4, corresponding to the hanger 33 along the length of the secondary keel 72. The multiple main keels 71 are perpendicular to the secondary keel 72, and the side of the multiple main keels 71 near the hanger 33 forms a fixing groove for opening the hanger 6. It should be noted that the curved painted aluminum panel unit 4 is installed under the ceiling steel frame structure transfer layer 3 by suspending a plumb line and pulling a horizontal line. The back of the painted aluminum panel is reinforced with ribs to increase the base back panel surface, and the two sides and the surface are fixed by pressing screws. When the painted aluminum panel is fixed by using a base clamp, the longitudinal horizontal base plate can be used as an auxiliary to first position the pre-arranged painted aluminum panel on the ceiling, observe whether its vertical angle or diagonal meets the installation conditions, and then fix it to the keel with screws after confirming that there are no errors.

[0036] Furthermore, the curved painted aluminum panel unit 4 includes a suspended ceiling 41 along the length of the structural floor slab 1 and a splicing part 42 that is vertically fixed to the suspended ceiling 41 and is used to connect adjacent curved painted aluminum panel units 4. One end of the suspended ceiling 41 and the splicing part 42 are connected to each other and extend outward relative to the splicing part 42 along the length of the structural floor slab 1.

[0037] Please see Figure 1 and Figure 3 As shown, a connecting keel 73 is fixedly installed on the second conversion rod 32 parallel to the hanging rod 33. The connecting keel 73 is fixedly connected to the splicing part 42 and the ceiling 41 of the adjacent arc-shaped painted aluminum plate unit 4 on one side relative to the second conversion rod 32.

[0038] Furthermore, a connecting rod 8 is fixedly installed on the second conversion rod 32 parallel to the hanging rod 33. A special hook 9 is fixedly installed on the end of the connecting rod 8 away from the second conversion rod 32 for fixing the end of the connecting rod 8 near the splicing part 42 of the adjacent arc-shaped painted aluminum plate unit 4 of the top 41 of the hanging rod 41.

[0039] The construction method for the large-area arc-shaped painted aluminum panel ceiling structure of this invention specifically includes the following steps:

[0040] Step 1: Positioning the spring axis

[0041] Pop up the decorative axis line according to the building axis line. Ensure that the deviation between the building axis line and the decorative axis line positioning line does not exceed 5mm to ensure the squareness of the finished decorative surface line.

[0042] Step 2: Place the finished noodles

[0043] Based on the decorative axis, mark the finished decorative line around the perimeter of the wall. Before marking the finished decorative line, be sure to accurately locate the decorative positioning axis to ensure that the installation position of the painted aluminum panel is accurate.

[0044] Step 3: Welding, installation, and rust removal of the steel frame conversion structure layer

[0045] The steel frame transfer structure layer is fixedly installed on the structural floor slab using embedded steel frame components. The welding and installation of the steel frame transfer layer is a crucial step in the construction of the painted aluminum panel ceiling. According to design requirements, galvanized square steel is welded and fixed to the concrete floor slab, with intervals between welded sections. It is important to note that when welding the steel frame, the horizontal longitudinal direction should be fixed first, followed by the horizontal transverse direction, to avoid deformation and ensure the flatness and verticality of the welded structural steel frame.

[0046] Step 4: Keel Installation

[0047] Install keels on one side of the steel frame transfer layer relative to the structural floor slab. If light steel keels are used as the base fixing components, first mark the longitudinal keels with chalk lines to position and fix them straight. Then, configure the main keels according to the size of the panel joints, ensuring that the keels and joints are properly constructed and fixed. Before installing the aluminum panels, it is best to conduct a trial installation to confirm that all dimensions and structures meet the requirements before proceeding with the formal installation. After completion, check the flatness of the panel surface and the drilling of fixing nails. Install the main keels first, and then install the secondary keels after the main keels are installed, and level them to improve the firmness and stability of the aluminum panels installed on the keels.

[0048] Step 5: Install the painted aluminum panels according to the layout.

[0049] According to the construction drawings, the painted aluminum panels are pre-laid out. Dividing lines for the curved painted aluminum panel units are marked on the keel, and the curved painted green dam units are installed according to the position of the dividing lines. Specifically, the aluminum panels are first cut, and the finished ceiling and wall surfaces are marked according to the site axis. The length and width of each finished surface are measured on site, and the collected measured data values ​​are returned to the design drawings. The measured dimensions on site are restored using architectural CAD software and the layout is carried out. The layout is confirmed to meet the design requirements. The ceiling aluminum panels are separated into blocks to create original files. Each curved aluminum panel is an independent dimension. According to the curved section drawing of the ceiling, we check the dimensions to ensure that the position of the dividing lines meets the requirements. Then, we mark the code on each aluminum panel drawing, and add a 25mm wide folded edge to all four sides of each aluminum panel.

[0050] Next, according to the separation and positioning, the first aluminum plate is first trial-assembled by stretching a long line. After confirming that it meets the conditions, it is fixed to the auxiliary hanging piece with phoenix tail nails. When installing the second aluminum plate, the two aluminum plates are locked together with the first aluminum plate by using phoenix tail nails. The other parts of the aluminum plate are fixed to the auxiliary hanging piece. The process is continued until the last aluminum plate is installed and fixed by personnel through the inspection port.

[0051] Step Six: Finishing Edges and Seam Treatment

[0052] After the curved painted aluminum panel unit is installed, edge trimming strips are used to finish the edges and the seams are treated. It should be noted that when installing painted panels, if there are louvers or return air, aluminum alloy trimming strips are used. When there are windows or glass, special edge trimming strips are used to finish the edges. Using metal edge trimming strips greatly reduces the risk of painted aluminum panels falling off and improves fire resistance and high temperature resistance safety and stability.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
