A first built-in plate is provided on the inner wall of the full-length keel close to the keel connector, and a second built-in plate is provided on the other opposite inner wall. The length of the second built-in plate is equal to the length of the full-length keel.

[0034] Preferably, when installing the keel connector, a second anti-corrosion gasket should be laid on the upper end surface of the decorative main board first, and then the keel connector should be placed on the second anti-corrosion gasket, and then locked and fixed to the decorative main board by fasteners.

[0035] Preferably, when an oblique cut is made on the decorative main board surface, an oblique cut surface is also cut on the upper surface of the decorative main board to ensure that the upper surface is parallel to the lower surface of the keel at its installation position during installation.

[0078] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0079] The present invention discloses a method for installing an aircraft wing space-shaped ceiling, which specifically comprises the following steps:

[0080] S1, constructing a three-dimensional model of the ceiling in three-dimensional software according to the construction data of the main wall structure 8 and the design drawings of the aircraft wing space-shaped ceiling, and extracting the keel point position data and the mortise and tenon type stacked ceiling decoration module connection hole positions from the model.

[0081] Specifically, the steps for constructing a three-dimensional ceiling model are as follows:

[0082] S11, after the main wall structure 8 is constructed, the construction data of the main wall structure 8 is collected, and the collected construction data is used to reproduce the main wall structure on-site model in 3D software;

[0083] S12, dividing the aircraft wing space-shaped ceiling into multiple ceiling units according to their structural characteristics and modeling them separately to obtain multiple three-dimensional ceiling sub-models;

[0084] Each ceiling unit includes a ceiling keel 9, a mortise and tenon type laminated ceiling decoration module 10 and a ceiling outer frame 11. The ceiling keel 9 includes a keel frame 12, a main keel 13 and a secondary keel 4. A plurality of main keels 13 are arranged at equal intervals in the keel frame 12. A plurality of secondary keels 4 are arranged between two adjacent main keels 13 and between the main keels 13 and the keel frame 12. A plurality of mortise and tenon type laminated ceiling decoration modules are arranged below between two adjacent main keels along the length direction of the main keels 13. The ceiling outer frame 11 is fixed to the keel frame 12 to enclose all the mortise and tenon type laminated ceiling decoration modules.

[0085] Specifically, the steps for the suspended ceiling 3D sub-model are:

[0086] First, draw the keel base plan in 3D software according to the design drawings of the aircraft wing space ceiling;

[0087] Then, the keel base diagram is divided into multiple unit keel bases according to the structural characteristics of the aircraft wing space-shaped ceiling;

[0088] Then, a 3D model of the mortise and tenon stacked ceiling decoration module is constructed and laid out on the base of each unit keel to obtain a 3D sub-model of each ceiling.

[0089] When arranging the mortise and tenon type laminated ceiling decoration modules, each mortise and tenon type laminated ceiling decoration module should be numbered sequentially;

[0090] S13, splicing each suspended ceiling 3D sub-model with the on-site model of the main wall structure, and adjusting the position of each suspended ceiling 3D sub-model according to the design drawings so that their respective elevations and dihedral angles meet the requirements;

[0091] S14, after the positions of the three-dimensional sub-models of the suspended ceiling are adjusted to the desired position, the keel point data and the connection hole positions of the mortise and tenon type stacked suspended ceiling decoration modules are extracted from the models.

[0092] The keel point data includes the three-dimensional coordinates of the installation position of each keel.

[0093] The mortise and tenon type stacked ceiling decoration module connection hole position refers to the three-dimensional coordinates of the mortise and tenon type stacked ceiling decoration module installation hole.

[0094] S2, reversely calculating the length of each wall connection hanger 7-1 based on the extracted keel point data and the design elevation of the finished ceiling surface.

[0095] Specifically, first, the reference axis of the main wall structure 8 is laid out on the ground and marked as a control axis;

[0096] Then, using the control axis system as a reference, the position of the boom is marked at the lower chord position of the main wall structure 8 using a laser total station according to the extracted keel point data;

[0097] Then, the elevation difference between the elevation at the lower chord hanger position of the main wall structure 8 and the design elevation of the finished ceiling surface at this position is calculated to obtain the length of the wall connection hanger 7-1 at this position.

[0098] S3, cutting the keel on site according to the extracted keel point data, and drilling decorative holes on the corresponding keel according to the connection hole positions of the mortise and tenon type laminated ceiling decoration module. The decorative holes are the installation holes of the mortise and tenon type laminated ceiling decoration module.

[0099] S4, using the cut keels to assemble the ceiling keels 9 of each ceiling unit on site.

[0100] S5, vertically fix the wall connecting hanger 7-1 at the corresponding position on the main wall structure 8.

[0101] S6. Use the connecting angle plates 7-2 to fix the ceiling panels 14 on the upper surfaces of the ceiling keels 9. Then, install the ceiling keels one by one from one end of the roof to the other, so that the connecting angle plates 7-2 of the ceiling keels are fixed to the wall connecting hangers 7-1. The elevations of the ceiling keels are different, and the dihedral angles between adjacent ceiling keels must meet the requirements.

[0102] S7, installing the mortise and tenon type stacked ceiling decoration modules on the ceiling keels with decorative holes drilled therein in the order of numbers, and sleeve the sleeve core 6 at the joints between two adjacent mortise and tenon type stacked ceiling decoration modules.

[0103] The mortise and tenon type laminated ceiling decoration modules are pre-assembled in advance. The assembly steps of a single mortise and tenon type laminated ceiling decoration module are as follows:

[0104] According to the design drawings of the mortise and tenon type laminated ceiling decoration module, a plurality of oblique cuts 1-7 are opened at corresponding positions on the surface of the decoration main board 1;

[0105] Place the two decorative main boards 1 in an oblique and symmetrical manner, with their respective upper ends close to the center;

[0106] The decorative sub-boards 2 corresponding to the number of cutouts are passed through the cutouts at different positions on the surface of the decorative main board 1 and are symmetrically connected to the two decorative main boards to achieve plug-in fixation, with the surfaces of the two adjacent decorative sub-boards 2 forming a set angle and the surfaces of the two spaced decorative sub-boards 2 being parallel;

[0107] A reinforcing connector 5 is fixed at a hidden position on the back of the connection between the decorative main board 1 and the decorative sub-board 2;

[0108] At least one keel connector 3 is fixed on the upper end surface of each decorative main board 1 .

[0109] When installing the keel connector 3, a layer of second anti-corrosion gasket 1-6 should be laid on the upper end surface of the decorative main board 1 first, and then the keel connector 3 should be placed on the second anti-corrosion gasket 1-6, and then locked and fixed with the decorative main board 1 through fasteners.

[0110] Preferably, when the oblique cuts 1-7 are formed on the decorative main board 1, an oblique cut surface is also cut on the upper surface of the decorative main board 1 to ensure that the upper surface is parallel to the lower surface of the keel at its installation position during installation.

[0111] The above method can be used to construct a space ceiling in the shape of an airplane wing. The ceiling comprises a plurality of ceiling units fixed to a main wall structure 8 via wall connectors 7. The size and elevation of each ceiling unit are different, and each ceiling unit forms a dihedral angle with each other. Figure 1 , Figure 1 In the embodiment shown, the entire ceiling is divided into six triangular ceiling units according to the length and width of the entire aircraft wing space-shaped ceiling. Each triangular ceiling unit has different side lengths and elevations, and forms dihedral angles with each other.

[0112] The structures of the ceiling units are the same. Figure 1 、 3 As shown, each comprises a ceiling keel 9, a plurality of mortise and tenon type stacked ceiling decoration modules 10 and a ceiling outer frame 11.

[0113] The ceiling keel 9 includes a keel frame 12 , a main keel 13 and a secondary keel 4 . A plurality of main keels 13 are arranged at equal intervals in the keel frame 12 , and a plurality of secondary keels 4 are arranged between two adjacent main keels 13 and between a main keel 13 and the keel frame 12 .

[0114] The entire ceiling keel 9 is fixed to the main wall structure 8 via a plurality of wall connectors 7 located on the upper surface of the main keel 13. The installation position of the wall connector 7 on the main wall structure 8 is determined according to the installation position of the ceiling keel 9 (the installation position is obtained through mechanical calculation). Each wall connector 7 includes a plurality of wall connection hangers 7-1 and a connection angle plate 7-2. For example, a certain installation position on the ceiling keel 9, such as Figure 2As shown, multiple wall-connecting hangers 7-1 are arranged along the length of the primary purlin 13 at this location. Connecting angle plates 7-2 are also arranged along the length of the secondary purlin 4 at this location. One end of the connecting angle plate 7-2 is fixed to all the wall-connecting hangers 7-1 at this location, and the other end is fixed to the secondary purlin 4 via bolts or screws. Preferably, the length of the connecting angle plate 7-2 is equal to the length of the secondary purlin 4, so that the connecting angle plate 7-2 can be fixed to all the wall-connecting hangers 7-1 at this hanging location. In this embodiment, the wall-connecting hangers 7-1 are supported by galvanized steel pipes, and the connecting angle plates 7-2 are supported by angle irons. The connecting angle plates 7-2 are arranged along the entire length of the secondary purlin 4.

[0115] In order to achieve the airplane wing shape effect, it is necessary to control the inclination of each ceiling unit by controlling the length of the wall connecting hanger 7-1, that is, to control the inclination of the ceiling keel 9. Therefore, the length of the wall connecting hanger 7-1 at different positions on each ceiling unit may be different.

[0116] The plurality of mortise and tenon stacked ceiling decoration modules are arranged below between two adjacent main keels along the length direction of the main keel 13 , that is, a plurality of rows of mortise and tenon stacked ceiling decoration modules are fixed below each ceiling keel 9 through the keel connector 3 .

[0117] The ceiling outer frame 11 is fixed to the keel frame 12 to enclose all mortise and tenon-jointed stacked ceiling decorative modules within the unit. Preferably, the ceiling outer frame 11 is fixed to the bottom of the keel frame 12, and the frame thickness of the ceiling outer frame 11 is greater than the frame thickness of the keel frame 12. The ceiling outer frame 11 is fixed to the bottom of the keel frame 12, and the ends of each main keel 13 and the ends of some secondary keels 4 connected to the keel frame are overlapped and fixed to the upper surface of the ceiling outer frame 11. The frame portion of the ceiling outer frame 11 extending into the keel frame can support the ends of the main keels 13 and some secondary keels 4, thereby ensuring the structural strength and stability of the ceiling keel 9.

[0118] The above-mentioned mortise and tenon type stacked ceiling decoration modules have the same structure, including a plurality of decoration main boards 1, a plurality of decoration sub-boards 2 and a plurality of keel connectors 3.

[0119] There are at least two decorative main boards 1. The decorative main boards 1 are arranged obliquely and symmetrically with their upper ends close to the center of the secondary keel 4. A keel connector 3 is fixed to the upper end surface of each decorative main board 1, and is fixed to the secondary keel 4 at its installation position through the keel connector 3.

[0120] There are multiple decorative sub-panels 2, and the multiple decorative sub-panels 2 pass through two symmetrical decorative main boards from different positions on the surface of the decorative main board 1 to be plugged and fixed with each decorative main board. The surfaces of two adjacent decorative sub-panels 2 form a set angle and the surfaces of the two spaced decorative sub-panels 2 are parallel.

[0121] Preferably, each decorative main board 1 is provided with a plurality of oblique cuts 1-7 on its surface, the cuts on each decorative main board are opened at the same position and the cuts at the same position have the same opening angle and opening shape, and the decorative sub-board 2 is inserted into the cut to be plugged and fixed with the decorative main board 1.

[0122] When making the incisions 1-7 on the decorative main board 1, the incisions 1-7 can be made from a certain position of the decorative main board 1 to its bottom surface to form a groove with an open lower end, or the incisions can be made from a certain position of the decorative main board 1 downward to another position to form a groove with no open lower end. However, the length of the incision must be consistent with the width of the decorative sub-board 2, and the width of the incision must be consistent with the thickness of the decorative sub-board 2.

[0123] To ensure the stability of the connection between the decorative main panel 1 and the decorative sub-panel 2, a fixed reinforcement connector 5 can be added to the hidden portion of the connection between the decorative main panel 1 and the decorative sub-panel 2. The reinforcement connector 5 is black anodized. In this embodiment, the reinforcement connector 5 is an angled connecting plate, one end of which is connected to the decorative main panel 1 via a fastener such as a rivet or screw, and the other end is connected to the decorative sub-panel 2 via a fastener such as a rivet or screw, thereby improving the stability of the connection between the decorative main panel 1 and the decorative sub-panel 2.

[0124] Preferably, in order to improve the aesthetics, the reinforcing connector 5 needs to be sprayed with a pattern having the same texture as the decorative main board 1 and the decorative sub-board 2 as a whole.

[0125] In this embodiment, Figure 6 As shown, two decorative main boards 1 are provided, and four decorative sub-boards 2 are provided. The two decorative main boards 1 are arranged obliquely and symmetrically with their upper ends close to the center. Each decorative main board 1 is provided with four oblique cutouts 1-7 with lower ends open. The four decorative sub-boards 2 are respectively inserted into the two decorative main boards 1 from the four cutout positions to achieve plugging with the decorative main boards 1. Among them, the first and third decorative sub-boards 2 are parallel and inclined to the upper right, and the second and fourth decorative sub-boards 2 are parallel and inclined to the upper left.

[0126] Preferably, as described above, since the ceiling keels 9 of each ceiling unit need to be tilted to different degrees, in order to fit with the upper end surface of the decorative main board 1 and the lower end surface of the secondary keel 4 to achieve a stable connection between it and the ceiling keel 9, the upper surface of the decorative main board 1 should be parallel to the lower surface of the secondary keel 4 at its position, that is, an oblique surface is beveled on the end surface of an ordinary plate with a rectangular cross-section, and the inclination angle of the oblique surface needs to be equal to the inclination angle of the ceiling unit.

[0127] like Figure 7As shown, the upper end of the decorative main board 1 is secured to the secondary keel 4 via a keel connector 3. The structure of the keel connector 3 is similar to that of the reinforcement connector 5, also being an angled connecting plate. However, a reinforcing rib is added between the two folded plates of the keel connector 3 to enhance the connection strength. In this embodiment, the keel connector 3 is made of hot-dip galvanized carbon steel. One end is secured to the secondary keel 4 via a bolt assembly, and the other end is secured to the decorative main board 1 via screws.

[0128] Preferably, a 1 mm thick second anti-corrosion gasket 1-6 is sandwiched between the contact surface of the keel connector 3 and the decorative main board 1 to prevent galvanic corrosion. At the same time, sealant can also be filled in the assembly gap of the first fastener 1-5 to increase the sealing performance.

[0129] Since the decorative main board 1 is tilted and the decorative sub-board 2 is plugged into it, a full-length keel assembly is embedded in the upper end of the decorative main board 1 in order to reduce its deflection and increase its bearing capacity.

[0130] like Figure 7 、 8 As shown in Figures 9 and 10, the full-length keel assembly 15 includes a full-length keel 1-1 and a first anti-corrosion gasket 1-2 embedded within the decorative main board 1. The full-length keel 1-1 extends along the entire length of the decorative main board 1, i.e., its length is equal to that of the decorative main board 1. The first anti-corrosion gasket 1-2 wraps around the outer periphery of the full-length keel 1-1. A first internal panel 1-3 is provided on the inner wall of the full-length keel 1-1 near the keel connector 3, and a second internal panel 1-4 is provided on the opposite inner wall. A first fastener 1-5 sequentially penetrates the keel connector 3, the body of the decorative main board 1, the first anti-corrosion gasket 1-2, the full-length keel 1-1, and the first internal panel 1-3 to secure the connection. A second fastener sequentially penetrates the first anti-corrosion gasket 1-2, the full-length keel 1-1, and the second internal panel 1-4 to secure the connection.

[0131] The first built-in panels 1 - 3 are relatively short and are only provided at the location where the keel connector 3 is arranged, so as to enhance the load-bearing capacity of the connection portion of the decorative main board 1 .

[0132] The length of the second built-in panel 1 - 4 is equal to that of the full-length keel 1 - 1 , and the second built-in panel 1 - 4 is arranged along the full-length keel 1 - 1 to enhance the structural strength of the entire length of the decorative main panel 1 .

[0133] In this embodiment, the full-length keel 1-1 is a 2mm thick U-shaped full-length keel, the first anti-corrosion gasket 1-2 wrapped around the full-length keel 1-1 is a 1mm thick anti-corrosion gasket, the first built-in plate 1-3 arranged on the inner wall of the full-length keel 1-1 is a 5mm thick iron sheet, and the second built-in plate 1-4 is a 2mm thick steel plate, and the full-length keel 1-1, the first built-in plate 1-3 and the second built-in plate 1-4 are all hot-dip galvanized.

[0134] Preferably, when arranging the above-mentioned mortise-and-tenon laminated ceiling decorative modules in rows, the decorative main panels 1 of the left and right mortise-and-tenon laminated ceiling decorative modules should be butted together. A sleeve core 6 should be positioned at the joint between the decorative main panels 1 of two adjacent mortise-and-tenon laminated ceiling decorative modules. The ends of the sleeve core 6 are inserted into the full-length keels of the left and right decorative main panels 1, respectively. In this embodiment, the sleeve core 6 is 3mm thick and is also hot-dip galvanized. By placing the sleeve core at the joint between two adjacent mortise-and-tenon laminated ceiling decorative modules, the integrity and deformation resistance of the entire decorative surface layer can be improved.

[0135] Preferably, because the mortise and tenon stacked ceiling decorative modules are of unusual shape, there are hollow spaces within individual modules and between adjacent modules. Therefore, to prevent the main wall structure 8 from being exposed and affecting the aesthetics, a roof panel 14 is laid on the upper surface of the ceiling keel. The shape and size of the roof panel 14 are the same as those of the keel frame 12. In this embodiment, the roof panel 14 is a 12 mm thick calcium silicate board, and its lower surface is coated with dark gray paint.

[0136] In this embodiment, the above-mentioned decorative main board 1 and decorative sub-board 2 are both aluminum alloy honeycomb aluminum panels, and their surface layers are roll-coated with imitation wood texture. The thickness of the decorative main board 1 is greater than the thickness of the decorative sub-board 2. Specifically, the decorative main board 1 can use a 50mm thick honeycomb aluminum panel, and the decorative sub-board 2 can use a 25mm thick honeycomb aluminum panel.

[0137] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
