Description

Technical Field

[0001] This invention belongs to the field of interior decoration technology, and in particular relates to an ultra-long prefabricated honeycomb aluminum panel ceiling system and its installation method. Background Technology

[0002] During ceiling construction, the conventional process generally uses a single-panel hook-and-loop connection method for ceiling installation. This process is usually suitable for ceiling projects of conventional height and size. Its core is to fix the edges of individual decorative panels with hook-and-loop components of adjacent panels to form a continuous ceiling surface. This method is widely used in conventional building decoration projects because of its relatively simple structure and high installation flexibility.

[0003] However, for a certain project involving a 2000㎡ extra-long honeycomb aluminum panel ceiling in a four-story atrium, even with the addition of a ceiling transition layer at the ceiling, the design height of the ceiling panels made of extra-long honeycomb aluminum panels from the ground still reached 38 meters. Furthermore, due to design requirements, the size of each extra-long honeycomb aluminum panel was 300mm*11000mm, and the quantity was approximately 700 panels. Honeycomb aluminum panels, as a lightweight and high-strength building material, are widely used due to their excellent compressive strength and thermal insulation properties. Traditionally, individual honeycomb aluminum panels are hooked together one by one to form the ceiling panels. However, in this ultra-high-altitude environment, the wind pressure difference between the ceiling and the lobby area poses a risk of detachment if the existing hooking method is used directly, creating a safety hazard. Furthermore, the project's exceptionally long panels (up to 11 meters in length) and the large-scale installation requirements make it difficult to control installation accuracy and quality. Working at height further amplifies the overall construction difficulty. The limitations of traditional single-panel hooking connections are significantly amplified in this scenario. If the conventional hooking panel process is still used for ceiling installation, the following problems will arise:

[0004] 1. Safety hazards exist: Ceilings installed using traditional hook-and-loop panels are susceptible to wind pressure in high-altitude areas, making them prone to falling or detaching. The overall safety factor is low, posing a significant safety risk. In addition, the assembly of the base steel frame in traditional methods often requires on-site welding. Welding at heights requires highly experienced welders, and there are construction risks associated with open flames during on-site welding.

[0005] 2. Difficult construction and installation: When using the traditional hook-and-loop installation process, each panel needs to be hoisted one by one. The numerous hoisting and splicing not only lead to a surge in the number of seams, but also affect the flatness and visual continuity of the ceiling surface due to the accumulation of installation errors. Furthermore, the repeated positioning and adjustment significantly reduce construction efficiency. During the hoisting process, the overall stability of these extra-long panels is weakened due to their length and weight, posing a risk of deformation or loosening. Installing these extra-long panels at high altitudes makes it even more difficult to control the flatness and uniformity of the gaps, and makes it even more difficult to meet the 5mm gap accuracy requirement required by the project design.

[0006] In conclusion, the traditional single-panel hook-and-loop connection method and single-panel hoisting method in the ceiling installation process are not suitable for the installation of a large number of extra-long panels at extremely high altitudes.

[0007] A search revealed that Chinese utility model patent CN220058519U discloses a snap-fit ​​combination quick ceiling installation structure, which "includes a ceiling frame main body for connecting the ceiling, with snap-fit ​​modules evenly distributed to form quick-fit slots corresponding to the ceiling panels; the ceiling panels include snap-fit ​​vertical plates, with fastener modules corresponding to and matching the snap-fit ​​modules on the snap-fit ​​vertical plates, and the quick-fit slots are combined to form a snap-fit ​​combination quick ceiling installation structure." However, this structure is difficult to adapt to the special needs of ultra-high altitude and ultra-long panels when assembling ceilings, and still has the following two problems: Firstly, the snap-fit ​​connection has limited wind pressure resistance. This structure relies on the snap-fit ​​modules and fastener modules to... While the design achieves a secure connection, the wind pressure difference between the ceiling and the lobby area at extremely high altitudes continuously affects the snap-fit ​​connection points. Prolonged wind impact could cause the snap-fit ​​modules to detach from the quick-release slots, posing a safety hazard of ceiling panel detachment. Furthermore, the design suffers from insufficient precision control over the installation of extra-long panels. Although the design mentions evenly distributed snap-fit ​​modules forming quick-release slots, for extra-long ceiling panels up to 11 meters in length, their weight and length can easily cause deformation during hoisting. Evenly distributed slots cannot completely offset the deformation stress of the extra-long panels, potentially leading to inaccurate control of panel gaps to meet design requirements. Additionally, the accumulation of installation errors from numerous spliced ​​extra-long panels can affect the overall flatness and visual continuity of the ceiling surface, presenting certain limitations. Summary of the Invention

[0008] To solve the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide an ultra-long prefabricated honeycomb aluminum panel ceiling system. Aiming at the construction problems of ultra-large spaces, ultra-high altitude areas and ultra-long aluminum honeycomb ceilings, through modular assembly and ground unitized construction, the installation nodes are optimized to form a closed ceiling system, which improves safety and construction efficiency, significantly reduces the number of hoisting times, and avoids the accumulation of flatness errors in the installation of traditional processes; moreover, through the method of the present invention, the ground and the ceiling can be constructed synchronously, effectively shortening the construction period, and bolt connections are used between components to avoid welding and hot work; in addition, the spacing and accuracy can be further controlled by the "well" - shaped positioning marks pre-processed and drawn on the back of the longitudinal connectors, improving the installation efficiency and ensuring the installation quality and stability.

[0009] To achieve the above object and other related objects, the present invention adopts the following technical solutions:

[0010] In the first aspect of the present invention, an ultra-long prefabricated honeycomb aluminum panel ceiling system is provided, which includes a ceiling conversion layer, a keel structure and a ceiling panel that are fixedly arranged on the structural roof from top to bottom; the ceiling panel is suspended and fixed on the keel structure; the ceiling panel includes a combined board and a trimming and adjusting board;

[0011] The keel structure includes main keels and secondary keels; the main keels are fixed on the ceiling conversion layer through suspender rods and hanging parts; the secondary keels are arranged longitudinally along the length direction of the combined board and are suspended on the main keels through hanging parts, so that the secondary keels can slide on the main keels in the installation direction and form an orthogonal grid-like structure with the main keels;

[0012] The combined board includes a plurality of single boards fixedly connected through a single-board connection component. The single-board connection component includes a transverse keel, a transverse connecting piece and a longitudinal connecting piece. Lapping boards and hooking boards are respectively arranged on the two long sides of the single board. The lapping board can be fitted on the hooking board, and a splicing joint is formed between adjacent two single boards through the lapping and hooking of the lapping board and the hooking board;

[0013] The combined board is successively and one by one suspended on the secondary keels and fixed after sliding in place in the installation direction. In the first suspended combined board, an auxiliary hooking piece for hanging and connecting with the secondary keel is also fixed on the first single board;

[0014] A transfer piece is arranged on the trimming and adjusting board. The upper end of the transfer piece is fixed with the hanging part. The trimming and adjusting board is suspended on the main keel through the hanging part and is closely attached to the last suspended combined board.

[0015] As a preferred technical solution, the single-board connecting components are evenly distributed along the length direction of the splice seam between the single boards, the transverse connecting members and the longitudinal connecting members are fixed on the transverse keel, the transverse connecting members are symmetrically distributed at both ends of the transverse keel, and the longitudinal connecting members are evenly distributed between the transverse connecting members and correspond to the position of the splice seam between two adjacent single boards.

[0016] As a preferred technical solution, the long side of the auxiliary hook is aligned with the length of the single board, the auxiliary hook is Z-shaped, and the upper end of the auxiliary hook has the same shape and size as the upper end of the hook board, while the lower end of the hook is fixed to the back side of the first single board.

[0017] As a preferred technical solution, the ceiling conversion layer includes a base steel frame and vertical steel frames. The top surface of the base steel frame is attached and fixed to the top plate of the structure. Several vertical steel frames are vertically fixed on the bottom surface of the base steel frame. Horizontal angle irons are fixed between two adjacent vertical steel frames so that each horizontal angle iron forms a mesh support structure. The hanging component is fixed to the horizontal angle irons by the hanging rod.

[0018] As a preferred technical solution, when two adjacent single boards are placed one after the other, the top lower end face of the overlapping plate of the later placed single board is attached to the top upper end face of the hook plate of the earlier placed single board.

[0019] Furthermore, a bolt passes through the overlapping plate and the hook plate, and the lower end of the bolt passing through the hook plate abuts against the outer side of the hook at the lower end of the secondary keel.

[0020] As a further preferred technical solution, in the first suspended panel of the composite panel, the overlapping plate of the first single panel is processed to have a width that matches the design gap.

[0021] Furthermore, the two long sides of the edge adjustment plate are provided with limiting flanges to ensure the design gap of the ceiling panel. The limiting flanges are processed to have a width that matches the design gap.

[0022] A second aspect of the present invention provides an installation method for an ultra-long prefabricated honeycomb aluminum panel ceiling system, applicable to any one of the ultra-long prefabricated honeycomb aluminum panel ceiling systems described above, comprising the following steps:

[0023] S1. Construction of ceiling transition layer and keel structure: Construct the ceiling transition layer and install the keel structure on the ceiling transition layer to ensure that the secondary keel can slide on the main keel in the installation direction through the hangers;

[0024] S2. Modular assembly construction of composite slabs on the ground: Successively place adjacent single slabs in front-to-back overlap along the width direction of the single slab on the ground, and after adjusting the spacing between adjacent single slabs, fixedly connect them through the single slab connection components to form a modular composite slab;

[0025] S3. Hoisting construction of composite slabs at the ceiling: Hoist each assembled composite slab one by one in sequence and hang it on the secondary keel, and push the composite slab in the installation direction to drive the secondary keel to slide on the main keel simultaneously until it moves in place, and then lower the composite slab to complete the limit fixation. Repeat the above steps until all composite slabs are installed;

[0026] S4. Suspend and fix the edge adjustment plate on the main keel, complete the installation of the ceiling panel, and form a complete ceiling system.

[0027] As a preferred technical solution, a "well" - shaped positioning mark is also drawn on the back of the longitudinal connecting member. The "well" - shaped positioning mark includes a central positioning point, horizontal parallel positioning lines, and vertical parallel positioning lines. The central positioning point is used for positioning and checking the straightness in the horizontal and vertical directions; the horizontal parallel positioning lines include two parallel horizontal lines with a spacing consistent with the width of the bottom plate of the horizontal keel, and both of the two parallel horizontal lines have slopes matching the installation angles of the corresponding horizontal keels on the composite slab, which are used for the installation positioning of the horizontal keels; the vertical parallel positioning lines include two parallel vertical lines with a spacing consistent with the preset spacing between adjacent single slabs, and both of the two parallel vertical lines are parallel to the length direction of the single slab, which are used to control the spacing between adjacent single slabs and at the same time to check the parallelism of the longitudinal connection seams between adjacent single slabs;

[0028] The step S2 includes the following specific steps:

[0029] First, determine the installation angles of the horizontal keels in the same length direction and the installation positions of each longitudinal connecting member according to the shape of the composite slab, and prepare suitable longitudinal connecting members;

[0030] Then, according to the determined installation positions of the longitudinal connecting members, take the vertical parallel positioning lines and the central positioning point as the adjustment reference, install the longitudinal connecting members between adjacent single slabs, and fixedly connect several single slabs required for a single composite slab in sequence through the longitudinal connecting members and self - tapping screws to form a modular composite slab;

[0031] Finally, install the horizontal keels on the composite slab through the transverse connecting members. Take the horizontal parallel positioning lines as the adjustment reference to make the longitudinal connecting members in the width direction form a straight line, and fix the horizontal keels, longitudinal connecting members, the later - placed single slab, and the previously - placed single slab through self - tapping screws to enhance the overall structural strength of the composite slab.

[0032] As described above, the present invention has the following beneficial effects:

[0033] (1) An ultra-long prefabricated honeycomb aluminum veneer ceiling system of the present invention improves the construction efficiency and the overall performance of the ceiling through standardized components and modular assembly methods. The ultra-long honeycomb aluminum veneer to be pre-installed is subjected to overall unitized construction and modular assembly on the ground, and is assembled and connected to the keel structure on the ceiling conversion layer through a modular hoisting method. The installation joints of the aluminum honeycomb veneer are optimized, so that the composite board, the keel structure and the ceiling conversion layer form a closed ceiling system, which not only avoids the risk of falling off of the aluminum honeycomb veneer caused by wind pressure, improves the overall safety performance of the ceiling, and solves the safety hazards existing in the traditional hook board process. At the same time, it also improves the on-site construction progress.

[0034] (2) An ultra-long prefabricated honeycomb aluminum veneer ceiling system of the present invention adopts a modular assembly process in which the veneers are spliced on the ground to form unit modules and then installed by integral hoisting. This not only breaks the traditional installation process, effectively reduces the number of hoisting times, making the number of hoisting times only one-fifth of that of the traditional hook board installation, and improves the construction efficiency; at the same time, by sliding each board in place one by one in the installation direction and then abutting front and back, it better solves the cumulative flatness error of the traditional process and improves the flatness of the overall board surface; in addition, ground assembly and ceiling hoisting can be constructed simultaneously, making the construction progress and construction quality controllable. While ensuring the construction quality, it greatly shortens the construction time, effectively saves the construction period, and can also improve the on-site conversion layer construction progress and avoid welding and fire.

[0035] (3) An ultra-long prefabricated honeycomb aluminum veneer ceiling system of the present invention combines multiple ultra-long aluminum honeycomb veneers into a group and splices and combines them into a unit module on the ground. The components are connected by bolts, which not only avoids on-site welding operations, but also ensures modular installation and stability; and, during the ground assembly process of the method of the present invention, a 5 mm gap can be evenly controlled by pads, improving the assembly and splicing quality of the unit module. At the same time, by controlling the overall width of the board unit, the width of the board unit is controlled within 1.5 meters to ensure stability during high-altitude hoisting installation and guarantee the construction quality; on this basis, by pre-processing and drawing a "well" - shaped positioning mark on the back of the longitudinal connecting piece, the use of pads is replaced. It can not only be used to control the interval between adjacent two veneers, realize the positioning of the transverse keel on the composite board, but also be used to check the straightness and parallelism, improving the installation efficiency and installation quality.

[0048] Example 1

[0049] like Figures 1 to 9 As shown, this embodiment provides an ultra-long prefabricated honeycomb aluminum panel ceiling system, including a ceiling transition layer, a keel structure, and ceiling panels arranged from top to bottom on the structural top slab of the main building; the keel structure includes a main keel 51 and a secondary keel 52; the ceiling panels are suspended and fixed on the keel structure and include a combination panel and an edge adjustment panel 7.

[0050] The ceiling transition layer is used to transfer loads and adjust height. It includes a base steel frame and vertical steel frames. The top surface of the base steel frame is fixed to the top plate of the structure. Several vertical steel frames are vertically fixed to the bottom surface of the base steel frame. A horizontal angle iron 11 is fixed between two adjacent vertical steel frames to form a mesh support structure. Several hanging parts 3 are fixed to the horizontal angle iron 11 by a hanger rod 2. In this embodiment, the hanger rod 2 is a stainless steel hanger rod with a diameter of 12mm. The top end of the hanger rod 2 is fixedly connected to the horizontal angle iron 11 of the ceiling transition layer by fasteners. The bottom end of the hanger rod 2 is provided with a threaded section. The top plate of the hanging part 3 is fixed to the hanger rod 2 through the threaded section. The height of the hanging part 3 can be adjusted by synchronously adjusting the position of the nuts and fasteners on both sides of the top plate of the hanging part 3 at the threaded section at the bottom end of the hanger rod 2.

[0051] The main keel 51 is fixedly connected to the transverse angle iron 11 via the hanger 3, so that each main keel 51 is evenly distributed and parallel to each other along the width direction of the combined plate, thereby improving the installation efficiency of the secondary keel 52 while ensuring its straightness. Several hangers 4 are provided on the secondary keel 52. In this embodiment, the main keel 51 has a C-shaped cross-section and a width of 50mm. The hanger 3 is a 50mm wide main keel 51 connector. The main keel 51 is placed in the groove of the hanger 3 and locked in place by bolts. The hanger 4 has a Z-shaped cross-section. The top of the hanger 4 has a slot that matches the main keel 51. The upper end of the hanger 4 is movably connected to the main keel 51 via the slot at the top. The lower end of the hanger 4 is fixedly connected to the secondary keel 52 via self-tapping screws. The spacing between adjacent self-tapping screws on the same secondary keel 52 along the length direction of the combined plate is 300mm.

[0052] like Figure 1 and Figure 2As shown, the secondary keel 52 is movably connected to the main keel 51 via the hanger 4. The secondary keel 52 is suspended on the main keel 51 and can slide along the length of the main keel 51. Furthermore, each secondary keel 52 is evenly distributed and parallel to each other along the length of the composite panel, so that the secondary keel 52 and the main keel 51 located between the composite panel and the ceiling transition layer form an orthogonal grid structure to stably support the composite panel. At the same time, the sliding of the secondary keel 52 on the main keel 51 can also ensure the straightness of the keel structure in the horizontal and vertical directions.

[0053] like Figure 1 and Figure 5 As shown, the composite panel includes several single panels 6. In this embodiment, the single panel 6 is an ultra-long honeycomb aluminum panel 6 with a width of 300mm and a length of 11000mm. Adjacent single panels 6 are fixedly connected by single panel connecting components 8, which are evenly distributed along the length direction of the single panel 6.

[0054] like Figure 1 and Figure 6 As shown, one long side of the single board 6 is provided with an overlapping plate 61 and the other long side is provided with a hook plate 62. The combined board is suspended and fixed to the secondary keel 52 through the hook plate 62. The secondary keel 52 is set along the length of the combined board. During operation, each combined board is hooked onto the secondary keel 52 in turn by moving laterally, and continues to move until the secondary keel 52 moves into place on the main keel 51.

[0055] like Figure 8 As shown, in the first assembled panel, the overlapping plate 61 of the first panel 6 is processed to have a width matching the design gap. Furthermore, the first panel 6 is also fixed with an auxiliary hook 63 for suspension connection with the secondary keel 52. The long side of the auxiliary hook 63 is aligned with the length of the panel 6. The auxiliary hook 63 is Z-shaped. The upper end of the auxiliary hook 63 has the same shape and height as the upper end of the hook plate 62, so that the panel surface can always remain horizontal and straight when the assembled panel is suspended from the secondary keel 52. The lower end of the hook is fixedly connected to the back side of the first panel 6.

[0056] In operation, two adjacent single panels 6 are placed one after the other. The top lower end of the overlapping plate 61 of the later-placed single panel 6 is attached to the top upper end of the hook plate 62 of the earlier-placed single panel 6, so that the two adjacent single panels 6 overlap end to end and improve the horizontal straightness of the ceiling panel, ensuring that the lower end of the ceiling panel is flush. In other embodiments, bolts can be used to pass through the overlapping plate 61 of the later-placed single panel 6 and the hook plate 62 of the earlier-placed single panel 6 in sequence to achieve a fixed reinforcement. At the same time, the lower end of the bolt passing through the surface of the hook plate 62 can abut against the outer side of the hook at the lower end of the secondary keel 52 to limit the position of the hook of the hook plate 62 at the hook, so as to improve the longitudinal straightness when splicing each combination panel.

[0057] like Figures 1 to 5 As shown, the single-board connection assembly 8 includes a horizontal keel 82, a horizontal connector 83, and a vertical connector 81.

[0058] The cross-section of the horizontal keel 82 is Z-shaped, including an upper folded edge, a middle vertical section, and a lower folded edge. The horizontal connecting member 83 and the longitudinal connecting member 81 are fixed to the horizontal keel 82. Specifically, the horizontal connecting member 83 is fixedly connected to the middle vertical section of the horizontal keel 82 and symmetrically distributed at both ends of the horizontal keel 82. Preferably, the fixing point between the horizontal connecting member 83 and the horizontal keel 82 is located on the horizontal centerline of the middle vertical section of the horizontal keel 82; the longitudinal connecting member 81 is fixedly connected to the lower folded edge of the horizontal keel 82 and is evenly distributed between the horizontal connecting members 83 located at both ends of the horizontal keel 82. The position of the longitudinal connecting member 81 corresponds to the position of the splicing seam between two adjacent single panels 6. In this embodiment, the fasteners used to fix the longitudinal connector 81 and the transverse keel 82 also penetrate through the overlapping plate 61 and hook plate 62 at the splice joint. That is, the fasteners used to fix the longitudinal connector 81 and the transverse keel 82 pass through the transverse keel 82, the longitudinal connector 81, the overlapping plate 61 of the later-placed single board 6, and the hook plate 62 of the first-placed single board 6 from top to bottom, and are locked in place. The spacing between adjacent longitudinal connectors 81 on the same transverse keel 82 is 600mm. In operation, the transverse keel 82 not only serves as a bridge for the modular overall connection, but also acts as a reinforcing rib for the unit module, enhancing the overall strength of the modular unit. At the same time, the inner side of the folded edge on the Z-shaped transverse keel 82 can also be used to install lighting fixtures or provide a basis for the layout and organization of various wiring inside the ceiling.

[0059] The transverse connector 83 is an L-shaped metal profile, including a vertical side and a horizontal side. The vertical side of the transverse connector 83 is fixed to the middle vertical section of the transverse keel 82 by bolt fasteners. At the same time, the horizontal side of the transverse connector 83 is fixed to the back side of the single board 6 by bolt fasteners. The transverse connector 83 forms a surface-to-surface reinforcement between the single board 6 and the middle vertical section of the transverse keel 82, which can improve the overall stability of the unitized module and further ensure the flatness of the combined board.

[0060] The longitudinal connector 81 has a Z-shaped cross section. Adjacent single panels 6 are fixedly connected by the longitudinal connector 81. The longitudinal connectors 81 at the splicing seam between the same pair of adjacent single panels 6 are evenly distributed along the length of the single panel 6. The Z-shaped structure can provide elastic buffering to adapt to the thermal expansion and contraction of the honeycomb aluminum panel, while dispersing the local stress at the screw fixing point and avoiding deformation of the honeycomb core layer under pressure.

[0061] like Figure 7 and Figure 9 As shown, the edge-trimming adjustment plate 7 is used for trimming the edges of all assembled panels. An adapter 71 is provided on the edge-trimming adjustment plate 7, which is parallel to the length of the edge-trimming adjustment plate 7. The lower end face of the adapter 71 is fixed to the back side of the edge-trimming adjustment plate 7, and the upper end of the adapter 71 is fixed with the hanging piece 4 to ensure that when the edge-trimming adjustment plate 7 is suspended from the main keel 51 by the adapter 71 and the hanging piece 4, the lower end face of the edge-trimming adjustment plate 7 is flush with the lower end face of the assembled panel. Limiting folds 72 are provided on both long sides of the edge-trimming adjustment plate 7. After processing, edge 72 has a width that matches the design gap, which is used to ensure the design gap of the ceiling panel. In this embodiment, the limiting folded edge 72 is bent into an L-shape according to the designed gap width, so that the width of the limiting folded edge 72 is consistent with the designed gap width. When bending, in order to ensure the gap is consistent, a pad 9 can be set. The side of the pad 9 is glued and fixed to the side of the edge adjustment plate 7 before bending. This not only makes it easy to ensure the width after processing, but also prevents the limiting folded edge 72 from deforming, so that the edge adjustment plate 7 and the wall 10 are always tightly attached, which strengthens the structure and also has a consistent aesthetic.

[0062] During operation, the edge trimming adjustment plate 7 is directly suspended from the main keel 51 via the hanger 4. At this time, one side limiting fold 72 of the edge trimming adjustment plate 7 is close to the side of the last suspended composite plate, and the other side limiting fold 72 of the edge trimming adjustment plate 7 is close to the structural wall 10. This ensures that the distance between the surface of the edge trimming adjustment plate 7 and the surface of the last suspended composite plate, as well as the distance between the surface of the edge trimming adjustment plate 7 and the structural wall 10, are consistent with the designed gap width. The length of the edge trimming adjustment plate 7 is slightly less than the length of the single plate 6 and is set along the length direction of the composite plate, allowing the edge trimming adjustment plate 7 to be hooked onto the main keel 51 by longitudinal movement.

[0063] Example 2

[0064] like Figures 1 to 9 As shown, this embodiment provides an installation method for an ultra-long prefabricated honeycomb aluminum panel ceiling system using Embodiment 1, including the following steps:

[0065] S1. Construct the ceiling transition layer on the ceiling and install the keel structure on the ceiling transition layer to ensure that the secondary keel 52 can slide in the installation direction on the main keel 51 through the hanger 4, providing a supporting foundation and sliding splicing space for the ceiling panel.

[0066] S1-1. After measuring and positioning the base steel frame according to the detailed design drawings of the composite slab, fix the top surface of the base steel frame to the top slab of the structure using angle brackets and expansion bolts, so that the base steel frame is installed on the top slab of the structure. The specific steps are as follows:

[0067] First, the scope and dimensions of the ceiling are determined according to the detailed design drawings of the composite panel. Then, the lengths of the vertical steel frame and the hanger 2 are determined according to the ceiling elevation and the original structural elevation. This ensures that the height difference between the lower end of the ceiling transition layer and the upper end of the ceiling panel is controlled within 500mm, thereby reducing the length of the hanger 2 installed on the vertical steel frame, enhancing the overall structural stability of the ceiling, and ensuring that the main keel 51 can be firmly suspended and fixed on the ceiling transition layer through the hanger 3 connected to the lower end of the hanger 2, thus providing stable support for the installation of the ceiling panel.

[0068] Then, after measuring and laying out the top slab of the structure, the base steel frame is placed in the predetermined position on the design drawings, and the top surface of the base steel frame is in contact with the top slab of the structure. Subsequently, the base steel frame is fixedly connected to the top slab of the structure using angle brackets and expansion bolts. As the basic support structure of the entire ceiling transfer layer, the base steel frame provides a stable foundation for subsequent installation by being firmly connected to the original top slab of the building structure. The specifications and quantity of the expansion bolts should meet the design requirements to ensure that the base steel frame can withstand the load during the subsequent installation process and to ensure that the connection is firm and reliable.

[0069] S1-2. Based on the single-panel 6 layout model on the detailed design drawings of the composite panel, determine the spacing of the vertical steel frame on the base steel frame, and determine the number of hangers 2 to be installed and the opening positions of the hanger 2 mounting holes on each horizontal angle iron 11 on the vertical steel frame, so as to meet the installation load-bearing requirements of the composite panel. The specific steps are as follows:

[0070] First, based on the arrangement order and spacing of the single-panel 6-row model on the detailed design drawings of the composite panel, determine the spacing position of the vertical steel frame on the base steel frame to ensure that the horizontal angle iron 11 passes through, thereby providing stable support for the composite panel.

[0071] Then, based on the specific position and arrangement direction of each panel 6 in the model, the setting direction of the main keel 51 and the setting spacing between the main keels 51 are determined. The setting direction of the main keel 51 is perpendicular to the arrangement direction of the panel 6 in the model, and the main keels 51 are set at intervals along the length direction of the panel 6. Further, based on the setting direction and spacing of the main keels 51, the position of the mounting hole of the hanger 2 on the horizontal angle iron 11 is determined, so that the hanger 2 can accurately pass through the mounting hole of the hanger 2 on the horizontal angle iron 11 and connect with the main keel 51, ensuring that each hanging point can accurately correspond to the corresponding position on the main keel 51, thereby ensuring the installation accuracy and stability of the ceiling panel.

[0072] At the same time, based on the length of a single panel 6 and the weight distribution of the combined panels in the single panel 6 layout model, the required number of hangers 2 is calculated and determined. Specifically, at least two hanging points are set on the horizontally arranged main keel 51 to ensure that each hanging point can reasonably share the load of the ceiling system, so that the entire ceiling is evenly stressed and avoids excessive local stress that could lead to structural deformation or damage.

[0073] S1-3. Based on the spacing of the vertical steel frame on the base steel frame, install the vertical steel frame on the base steel frame and set the horizontal angle iron 11 on the vertical steel frame: the upper part of the vertical steel frame is fixedly connected to the angle iron with a side length of 50mm by through bolts, so that the vertical steel frame is installed on the base steel frame. At the same time, the lower part of the vertical steel frame is fixedly connected to the horizontal angle iron 11 by through bolts to form a mesh structure, thus completing the installation of the ceiling conversion layer.

[0074] The installation of the vertical steel frame includes the following specific steps: First, the upper part of the vertical steel frame is placed vertically on the base steel frame. Measurements are taken to ensure the position and spacing of the vertical steel frame meet the design requirements. Then, the upper part of the vertical steel frame is fixedly connected to the 50mm side brackets on the base steel frame using through bolts. These through bolts must be tightened to the specified torque to ensure the stability of the vertical steel frame and prevent displacement or shaking during subsequent construction. Finally, the horizontal angle irons 11 are sequentially fixed to the lower part of the vertical steel frame using through bolts. This forms a stable mesh support structure, which together with the base steel frame constitutes the skeleton of the ceiling transition layer, bearing the role of support and load transfer. Among them, the horizontal angle irons 11 are distributed according to the design requirements. In this embodiment, the vertical steel frame is made of angle iron with a side length of 50mm. The spacing between adjacent horizontal angle irons 11 matches the spacing between vertical steel frames and forms a mesh structure perpendicular to each other with the vertical steel frames, thereby providing a good foundation for the subsequent installation of the main keel 51 and improving the overall strength and stability of the ceiling transition layer steel frame.

[0075] S1-4. Based on the opening positions on the transverse angle iron 11 and the number of hangers 2 to be installed, hanger 2 mounting holes are opened on the transverse angle iron 11 for installing hangers 2. Hangers 3 for suspending and fixing the main keel 51 are installed at the lower end of the hangers 2 and adjusted to the same height of each hanger 3. The hangers 2 used to connect the main keel 51 are then installed in sequence at the hanger 2 mounting holes. The spacing of the openings on the transverse angle iron 11 is determined according to the single-panel 6 layout model on the composite panel detailed design drawing.

[0076] The specific steps in the process of drilling holes in the transverse angle iron 11 and installing the hanger 2 are as follows: First, the hanger 2 mounting holes are drilled above the transverse angle iron 11 at the spacing required by the design; then, the top end of the hanger 2 is passed through the hanger 2 mounting holes on the transverse angle iron 11 and threadedly connected to the transverse angle iron 11 with fasteners; finally, the hanger 3 is installed at the threaded section at the bottom end of the hanger 2 with fasteners.

[0077] In this embodiment, the hanger rod 2 is made of stainless steel with a diameter of φ12mm. The spacing between the mounting holes of adjacent hanger rods 2 is 600mm, and the size of the mounting holes of each hanger rod 2 matches the diameter of the hanger rod 2 of φ12mm. Furthermore, the vertical steel frame is connected by bolts, and the horizontal angle iron 11 can be directly processed in the back-end and assembled on site, which can avoid on-site welding processes, ensure precise positioning of carpentry operations, reduce welding processes and workload, avoid open flames on site, ensure construction safety, and facilitate later maintenance.

[0078] S1-5. The main keel 51, which serves as the main load-bearing keel, is fixedly connected to the ceiling transition layer through the hanger 3 at the bottom of the hanger 2, and the secondary keel 52 is hung on the main keel 51 through the hanger 4. The specific steps are as follows:

[0079] First, determine the installation direction of the main keel 51 according to the arrangement direction of the single panels 6 in the design panel, ensuring that the length direction of the main keel 51 is perpendicular to the length direction of the single panel 6. Then, place the main keels 51 in the hangers 4 in sequence and lock them in place with fasteners. This ensures that the main keels 51 corresponding to the same panel are evenly distributed along the length direction of the single panel 6, and ensures the straightness and stability of the main keels 51, providing a precise support foundation for the installation of the ceiling panel.

[0080] Then, according to the spacing of the main keel 51, the hanging parts 4 are fixed sequentially on the secondary keel 52 along their own length direction, so that the upper slot of the hanging part 4 is perpendicular to the length direction of the secondary keel 52.

[0081] Finally, the secondary keel 52 is hung on the main keel 51 using the hanger 4, so that the hanger 4 is located on the side of the hanger 3 closer to the installation direction. In this embodiment, by placing the hanger 4 close to the hanger 3, the starting points of movement of each hanger 4 in the length direction are consistent, forming an adjustable adaptive suspension structure, which facilitates the subsequent installation of modular combination panels one by one.

[0082] At this point, the installation of the ceiling transition layer and the keel structure is complete. In this embodiment, the secondary keel 52, as a secondary load-bearing keel, forms discrete support nodes through its continuous, full-length arrangement and spaced Z-shaped hangers 4, dispersing and transferring the load of the directly supported ultra-long composite panel to the main keel 51. Simultaneously, the main keel 51, as the primary load-bearing keel, forms symmetrical support nodes with its large cross-sectional stiffness and symmetrically arranged hangers 4, and transfers the load to the ceiling transition layer through the hangers 2 and hangers 3, ultimately transferring it from the transition layer to the main building structure, effectively improving the overall stability of the modular composite panel prefabricated ceiling. Furthermore, the spaced fixing of the main keel 51 along the length of the secondary keel 52 provides multiple support constraints for the secondary keel 52, limiting its longitudinal flexural deformation. The secondary keel 52, covering its entire length, further provides continuous support for the panels at the joints of adjacent composite panels, effectively limiting longitudinal flexural deformation and ensuring the flatness of the ceiling surface.

[0083] S2. Modular assembly construction of the composite panels on the ground: Along the width direction of the single panel 6, each pair of adjacent single panels 6 are placed on the ground with their front and back overlapping, and after adjusting the spacing between adjacent single panels 6, they are fixedly connected by the single panel connecting components 8 to form a modular composite panel.

[0084] S2-1. Pre-arrange the individual panels 6 on the same composite panel to ensure that the spacing between adjacent panels 6 meets the preset interval required by the panel 6 layout model: According to the panel 6 layout model on the composite panel detailed design drawings, place the panels 6 required for a single composite panel one by one on a flat ground, so that the overlapping plate 61 on the later-placed panel 6 overlaps the hook plate 62 on the earlier-placed panel 6, and place them one by one until the number of panels 6 required to form a single composite panel is reached. In this embodiment, the number of panels 6 in a single composite panel is 4. Preferably, in order to facilitate hoisting, the length direction of the panel 6 is adjusted to be consistent with the length direction designed in the drawings during placement to reduce the swaying and twisting of the extra-long panels 6 during suspension. At the same time, ensure that the spacing between the panels 6 is the same as the preset interval.

[0085] In this embodiment, a pad 9 is placed between two adjacent single boards 6 to control the spacing between them. The pad 9 has the same width as the preset interval between the two adjacent single boards 6 so that the spacing between the two adjacent single boards 6 is consistent with the design requirements.

[0086] S2-2, as shown Figure 1 and Figure 5 As shown, adjacent single panels 6 are fixed sequentially using the single panel connecting assembly 8: the installation angle of the transverse keel 82 along the same length direction is determined according to the shape of the combined panel, and then the installation position of each longitudinal connector 81 used to connect adjacent single panels 6 is determined. The longitudinal connectors 81 are installed between adjacent single panels 6 to complete the initial fixing between the single panels 6, and the transverse keel 82 is installed. The specific steps are as follows:

[0087] First, the installation angles of the transverse keels 82 along the same length direction and the installation positions of each longitudinal connector 81 are determined according to the shape of the composite panel. When the composite panel has a regular geometric shape, its center of gravity is evenly distributed. At this time, the two adjacent transverse keels 82 along the length direction of the same single panel 6 are parallel to each other. In this embodiment, the composite panel is a regular long rectangle, so the installation spacing of each longitudinal connector 81 can be determined to be the same and consistent with the parallel spacing between the two adjacent transverse keels 82. When the composite panel has an irregular shape, its center of gravity is shifted. At this time, the installation angles of the transverse keels 82 along the length direction of the same single panel 6 can be redesigned according to the center of gravity of the composite panel, and then the installation spacing of each longitudinal connector 81 used to connect adjacent single panels 6 can be determined. For example, in another embodiment, the transverse keels 82 along the same length direction can be connected end to end in an intermittent V-shape. By installing each transverse keel 82 on the composite panel at different angles, the stress stability can be ensured.

[0088] Then, according to the determined installation position of the longitudinal connector 81, the longitudinal connector 81 is installed between adjacent single boards 6. Several single boards 6 required for a single composite board are sequentially fixed together using the longitudinal connector 81 and self-tapping screws to form a modular composite board. Specifically, the longitudinal connector 81 is first fixed sequentially at both ends along the length of the single board 6 to achieve initial positioning and fixing of adjacent single boards 6 on the same composite board. This ensures that the spacing between adjacent single boards 6 on the same composite board meets the requirements of the single board 6 layout model, reducing the risk of displacement. Subsequently, the remaining longitudinal connectors 81 are sequentially fixed along the length of the single board 6. When fixing the longitudinal connector 81, the two side flanges of the longitudinal connector 81 are first adjusted to be parallel to the length of the single board 6, and then fixed to the back side of adjacent single boards 6 using self-tapping screws. The spacing between adjacent self-tapping screws on the same side flange of the same longitudinal connector 81 is 400mm.

[0089] Finally, a horizontal keel 82 is installed on the composite panel using a horizontal connector 83, so that each longitudinal connector 81 in the width direction is connected in a straight line. The horizontal keel 82, longitudinal connector 81, the later-placed single panel 6, and the earlier-placed single panel 6 are fixed with self-tapping screws to enhance the overall structural strength of the composite panel.

[0090] S2-3. Repeat steps S2-1 and S2-3 to complete the assembly of each combination board in sequence.

[0091] By assembling modular panels in batches, the ceiling installation of the previous panel can be carried out while the floor assembly of the next panel is being carried out. Through simultaneous construction, the construction time can be greatly shortened while ensuring construction quality.

[0092] S3. Hoist each assembled panel one by one to hook it onto the secondary keel 52, and push the panel in the installation direction to drive the secondary keel 52 to slide on the main keel 51 until it moves into place. Then lower the panel to complete the limit fixation. Repeat the above steps until all panels are installed.

[0093] S3-1. Suspend and move the combined panel to the vicinity of the intended installation position, so that the combined panel is located on the side of the secondary keel 52 away from the installation direction, and the height of the combined panel is slightly higher than the intended installation height, so as to ensure that the lowest point of the auxiliary hook 63 on the first suspended combined panel and the lowest point of the hook plate 62 on each combined panel are higher than the highest point of the hook part on the secondary keel 52.

[0094] S3-2. Hook the hook plate 62 on the combination plate onto the hook part of the secondary keel 52, and push the combination plate in the installation direction to drive the secondary keel 52 to slide on the main keel 51 to its position. Lower the combination plate to use its own weight to complete the limiting and fixing of each combination plate: such as Figure 2 and Figure 8As shown, move the first suspended panel to abut against the structural wall 10, and then move the subsequent suspended panels to abut against the previous suspended panel. Repeat the above steps until all panels have been moved into place and fixed. The specific steps are as follows:

[0095] First, the auxiliary hooks 63 and hook plates 62 on the first suspended combination plate are simultaneously hooked onto the two secondary keels 52 closest to the structural wall 10. The plate is then pushed horizontally until the horizontal end face of the overlapping plate 61 on the side of the first suspended combination plate closest to the installation direction is in contact with the structural wall 10. In this embodiment, after the overlapping plate 61 on the side of the first suspended combination plate closest to the installation direction is bent or cut, the distance between its horizontal end face and the outer end face of the combination plate is consistent with the designed gap width. This ensures that no additional gap adjustment is needed when the horizontal end face of the first suspended combination plate is in contact with the structural wall 10, achieving the desired fit in one step.

[0096] Subsequently, the hook plate 62 on the side away from the installation direction of the subsequent suspended combination plate is hooked onto the next keel 52, and then pushed horizontally until the side of the pad 9 on the vertical end face of the overlapping plate 61 on the side near the installation direction of the combination plate is in contact with the outer end face of the hook plate 62 on the side away from the installation direction of the previous suspended combination plate. That is, after hooking the hook plate 62 on the side away from the installation direction of the subsequent suspended combination plate onto the next keel 52, the overlapping plate 61 on the side near the installation direction of the combination plate is pushed horizontally onto the hook plate 62 of the previous suspended combination plate at the previous keel 52.

[0097] This method utilizes the contact between the combined panel and the wall 10, the contact between the next combined panel and the previous combined panel, and the self-weight of each combined panel to complete the positioning and fixing of each combined panel. It is only necessary to ensure the accuracy of the first installed combined panel. When subsequent combined panels are installed in sequence, they can be slid to contact the previous combined panel to ensure flatness and straightness. No additional measurement and adjustment are required, which is conducive to quickly solving the problem of uneven splicing of ultra-long suspended ceilings at ultra-high altitudes.

[0098] S4. Assemble the edge trim adjustment panel 7 on the ground and suspend and fix the edge trim adjustment panel 7 to the main keel 51 through the hanger 4 on the adapter 71 to complete the installation of the ceiling panel and form a complete ceiling system.

[0099] S4-1. Assemble the edge trimming adjusting plate 7 on the ground, and install the adapter 71 and the hanging part 4 on the edge trimming adjusting plate 7: First, place the edge trimming adjusting plate 7 on a flat ground, and adjust it to be consistent with the length direction of the single board 6 on the composite board for hoisting. Fix the adapter 71 on the back side of the edge trimming adjusting plate 7, so that the length direction of the adapter 71 is perpendicular to the length direction of the main keel 51. Subsequently, fix the hanging part 4 on the adapter 71, and the distance between adjacent hanging parts 4 on the same adapter 71 is the same as the distance between adjacent main keels 51.

[0100] S4-2. As Figure 9 shown, hang and fix the edge trimming adjusting plate 7 on the main keel 51: First, suspend and lift the edge trimming adjusting plate 7 and move it to near the preparatory installation position, and make the height of the edge trimming adjusting plate 7 slightly higher than the preparatory installation height, that is, the lowest point of the upper groove edge of the hanging part 4 on the edge trimming adjusting plate 7 is higher than the upper end face of the main keel 51. At this time, the limiting folding edges 72 at the two long sides of the edge trimming adjusting plate 7 are respectively in contact with the structural wall surface 10 and the last hung composite board, and the design gap width of the ceiling panel can be satisfied through the limiting folding edges 72. Then, move the edge trimming adjusting plate 7 towards the main keel 51 until the end face of the vertical section of the hanging part 4 is in contact with the side surface of the main keel 51. Subsequently, completely lower the edge trimming adjusting plate 7 until the upper end face of the main keel 51 is in contact with the bottom of the upper groove of the hanging part 4, complete the installation of the ceiling panel, and form a complete ceiling system.

[0101] Example 3

[0102] This embodiment provides another ultra-long prefabricated honeycomb aluminum plate ceiling system and its installation method.

[0103] The difference between the ultra-long prefabricated honeycomb aluminum plate ceiling in this embodiment and that in Example 1 is that: a "well" - shaped positioning mark is also drawn on the back of the longitudinal connecting member 81. The "well" - shaped positioning mark is determined according to the shape of the composite board and is used to realize the positioning connection of the transverse connecting member 83. The "well" - shaped positioning mark includes a central positioning point, transverse parallel positioning lines, and longitudinal parallel positioning lines. The central positioning point is used for positioning and checking the straightness in the transverse and longitudinal directions. The transverse parallel positioning lines include two parallel horizontal lines with a distance equal to the bottom plate width of the transverse keel 82. Both of the two parallel horizontal lines have slopes matching the installation angles of the corresponding transverse keels 82 on the composite board and are used for the installation positioning of the transverse keels 82. In this embodiment, the two parallel horizontal lines are symmetrically distributed along the central positioning point to ensure that the transverse keels 82 always fall on the symmetry axis of the longitudinal connecting member 81. The longitudinal parallel positioning lines include two parallel vertical lines with a distance equal to the preset interval between adjacent single boards 6. Both of the two parallel vertical lines are parallel to the length direction of the single board 6 and are used to control the distance between adjacent single boards 6. At the same time, they can be used to check the parallelism of the longitudinal connection seams between adjacent single boards 6, without setting additional tools such as the spacer 9, which improves the installation efficiency.

[0104] The difference between the described installation method and that of Embodiment 2 is as follows: In Embodiment 2, when modular assembly construction of the composite board is carried out on the ground in step S2, spacers 9 are placed between two adjacent single boards 6 to control the distance between the two adjacent single boards 6. However, when bonding the spacers 9 inside the overlapping board 61 of the single board 6, not only is it easy to accumulate artificial bonding errors, but also due to the extra-long length of the single board 6, the manual workload and the weight of the composite board are increased. In addition, when the composite board is irregularly shaped, the manual measurement and positioning required for installing the transverse keels 82 at different angles are relatively time-consuming and there is an accumulation of manual measurement errors. In this embodiment, by pre-drawing a "well" - shaped positioning mark on the longitudinal connecting member 81 according to the design drawing during the factory production stage, the design gap between two adjacent single boards 6 and the positioning and inspection of the installation angle of the transverse keel 82 can be simply and quickly achieved at the installation site. Only the spacers 9 for controlling the installation distance between adjacent composite boards are retained, significantly reducing the usage amount of the spacers 9, lowering the labor cost, and reducing the weight of the composite board.

[0105] In other words, step S2 - 2 of this embodiment includes the following specific steps:

[0106] First, determine the installation angle of the transverse keels 82 in the same length direction and the installation positions of each longitudinal connecting member 81 according to the shape of the composite board, and prepare suitable longitudinal connecting members 81.

[0107] Then, according to the determined installation positions of the longitudinal connecting members 81, with the longitudinal parallel positioning line and the center positioning point as the adjustment reference, install the longitudinal connecting members 81 between two adjacent single boards 6, and sequentially fix and connect several single boards 6 required for a single composite board through the longitudinal connecting members 81 and self - tapping screws to form a modular composite board: Specifically, first place one longitudinal connecting member 81 at each end of the splicing seam between two adjacent single boards 6. Taking the parallel longitudinal line on the back side of the longitudinal connecting member 81 as the reference, adjust the position of the longitudinal connecting member 81 until one side parallel longitudinal line is aligned with the edge of the previously placed single board 6. By ensuring that the two points where this side parallel longitudinal line intersects with the edge of the longitudinal connecting member 81 both fall on the edge of the single board 6, it can be ensured that the parallel longitudinal line at this time completely coincides with the edge of the single board 6.

[0108] Subsequently, the side wing plate of the longitudinal connector 81 is fixed to the first-placed veneer 6 using at least two fasteners to ensure that the longitudinal connector 81 does not shift. The overlap position of the second-placed veneer 6 on the first-placed veneer 6 is adjusted so that the edge of the second-placed veneer 6 is aligned with the parallel longitudinal line on the other side. At the same time, it must be confirmed that the parallel longitudinal lines on the other side of the longitudinal connector 81 at both ends of the splice are completely aligned with the edge of the second-placed veneer 6. The other side wing plate of the longitudinal connector 81 is fixedly connected to the second-placed veneer 6 using at least two fasteners. The spacing between the first-placed veneer 6 and the second-placed veneer 6 can be controlled at four points to be consistent with the preset interval and to prevent displacement.

[0109] Next, using the center positioning points on the longitudinal connectors 81, the remaining longitudinal connectors 81 were adjusted and fixed one by one. The slope of the line connecting the center positioning points on the longitudinal connectors 81 at different joints was checked in real time to ensure it matched the slope of the intended installation angle of the transverse keel 82.

[0110] Finally, the horizontal keel 82 is installed on the composite panel using the horizontal connector 83. Using the horizontal parallel positioning line as the adjustment reference, the longitudinal connectors 81 in the width direction are aligned into a straight line. The horizontal keel 82, longitudinal connectors 81, the later-placed single panel 6, and the earlier-placed single panel 6 are then fixed with self-tapping screws to strengthen the overall structural strength of the composite panel. Specifically, using the horizontal parallel positioning line as the adjustment reference, the installation angle of the horizontal keel 82 can be quickly positioned by aligning the two sides of the lower folded edge of the horizontal keel 82 with the two parallel horizontal lines on the longitudinal connector 81, ensuring the horizontal keel 82 is properly positioned. The installation angle of 2 meets the design requirements; then, the horizontal keel 82 is fixedly connected to the two single boards 6 with the farthest distance on the combined board through the horizontal connectors 83 located at both ends of the horizontal keel 82; next, by passing self-tapping screws from top to bottom through the lower folded edge of the horizontal keel 82, the longitudinal connector 81, the overlapping plate 61 of the later placed single board 6, and the hook plate 62 of the first placed single board 6, the horizontal keel 82 can be used as a reinforcing rib to ensure the overall rigidity of the modular unit board, so as to achieve the reinforcement and fixation at the splice seam of each single board 6 on the combined board, improve the overall support structure strength of the combined board, and reduce the risk of deformation.

Both of the two parallel vertical lines are parallel to the length direction of the single board, and are used to control the interval between adjacent single boards and at the same time to check the parallelism of the longitudinal connection seams between adjacent single boards; The step S2 includes the following specific steps: First, determine the installation angles of the horizontal keels in the same length direction and the installation positions of each longitudinal connecting piece according to the shape of the composite board, and prepare appropriate longitudinal connecting pieces; Then, according to the determined installation positions of the longitudinal connecting pieces, take the vertical parallel positioning lines and the central positioning point as the adjustment benchmarks, install the longitudinal connecting pieces between adjacent single boards, and fix and connect several single boards required for a single composite board in sequence through the longitudinal connecting pieces and self - tapping screws to form a modular composite board; Finally, install the horizontal keels on the composite board through the transverse connecting pieces. Take the horizontal parallel positioning lines as the adjustment benchmarks to make the longitudinal connecting pieces in the width direction form a straight line, and fix the horizontal keels, longitudinal connecting pieces, the later - placed single board, and the previously - placed single board through self - tapping screws to strengthen the overall structural strength of the composite board.
