Abstract

The present invention discloses an adjustment and installation system for a hyperbolic-shaped single-curved ceiling and its construction method, which includes a roof main steel structure, a conversion layer structure, and a hyperbolic-shaped ceiling. The conversion layer structure includes a vertically suspended steel frame, a main keel adjusted along the plate direction, a hanging secondary keel, a keel attitude adjustment component, and a ceiling hanging adjustment component. The two ends of adjacent keel segments and the bottom end of the suspender are adjustably connected through the keel attitude adjustment component.

Description

Technical Field

[0001] The present invention relates to the technical field of decorative ceiling construction, and particularly relates to an adjustment installation system for a double-curved single-curved arc ceiling, its construction method, and its construction technique. Background Art

[0002] With the continuous development of architectural design, more and more construction projects are beginning to pursue unique decorative effects, especially high-end projects and landmark buildings. Through carefully designed double-curved shapes and unique surface visual treatments, the interior decoration of buildings presents a perfect combination of dynamics and modernity.

[0003] Currently, for the interior decoration ceiling panels with double-curved shapes, multiple double-curved arc panels are usually spliced. Since the sizes and shapes of each double-curved arc panel to be spliced are often different, it is necessary to import them into a modeling program for fitting positions in advance, then process them individually in the factory, and then perform positioning and installation on-site, which is very cumbersome.

[0004] Therefore, designers design the interior decoration ceiling panels with double-curved shapes to be formed by a group of single-curved arc aluminum strips arranged at intervals. The gap space between the arc aluminum strips appears black under indoor light, so that the alternately arranged single-curved arc aluminum strips and the gap space not only can form a double-curved shape, but also form a striped interior decoration ceiling panel in terms of visual effect, eliminating the processing and on-site installation of double-curved arc panels, and only requiring the processing and positioning of single-curved arc aluminum strips.

[0005] In order to achieve the visual effect, the existing single-curved arc aluminum strips are designed in the way of equal gaps but unequal plates, that is, the width of the gaps between the strips remains unchanged, and the entire double-curved surface change is mainly adjusted by the width of the strips. Since the double-curved surface is generated by a Bezier curve, in order to ensure that the gaps remain unchanged, the top and bottom of the same strip will inevitably have different widths, and the width of the bottom aluminum plate is greater than that of the top aluminum plate, that is, the shape of the strip is fan-shaped after being flattened. And the fan-shaped strip can only be realized by the welding process. Because the plate surface is relatively narrow, the thermal melting deformation and stress change generated during the welding process are uncontrollable, and the arc of the final finished plate surface cannot match the arc in the BIM model, ultimately affecting the decorative effect.

[0006] At the same time, the attitude adjustment of the keel is generally carried out through the connection node between the suspension rod and the back side of the keel. The adjustment dimension is small, and the adjustment construction is extremely inconvenient. The suspension rod usually cannot be adjusted in spatial position at a single point after installation, resulting in difficult adjustment of the ceiling installation position once there is a large deviation in the installation position of the suspension rod. In addition, the traditional ceiling panel is a single aluminum veneer, which is not conducive to roll forming during processing. Therefore, there is an urgent need for an installation system for single-curved arc ceiling strips and its construction method to avoid the above problems. Summary of the Invention

[0007] The object of the present invention is to provide an adjustment and installation system for a double-curved single-curved arc ceiling and its construction method, aiming to solve the technical problem of the cumbersome construction of multiple splicings of the interior ceiling boards with a double-curved shape; and to solve the technical problem that in the design of the existing single-curved arc aluminum strip boards, when using the method of equal seams and unequal boards and welding to achieve fan-shaped strip boards, uncontrollable deformation and stress changes will occur to the board body, resulting in the board surface radian of the final finished product not being able to reach the final design effect; and to solve the technical problem of the great difficulty in single-point space adjustment of traditional suspenders and the disadvantage of single aluminum veneer processing for roll forming.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0009] An adjustment and installation system for a double-curved single-curved arc ceiling, comprising a roof main steel structure, a conversion layer structure and a double-curved shape ceiling. The double-curved shape ceiling is adjustably connected to the roof main steel structure through the conversion layer structure.

[0010] The roof main steel structure is a double-curved grid structure, including a group of main beams with a single-curved arc protruding outward vertically. The main beams are arranged at intervals along the transverse direction in columns.

[0011] The double-curved shape ceiling includes a group of ceiling boards with a single-curved arc protruding outward vertically. The ceiling boards are arranged at intervals along the transverse direction in columns. The board widths of each ceiling board are the same. The board seams between adjacent ceiling boards are variable-width seams, forming a state of equal boards and unequal seams between the ceiling boards and the board seams. Each column of ceiling boards is composed of ceiling board segments with different heights spliced in series along the board direction. Each ceiling board segment is a single-curved arc.

[0012] The conversion layer structure includes a vertically suspended steel frame, a main keel for adjustment along the board direction, a hanging secondary keel, a keel attitude adjustment component and a ceiling hanging adjustment component.

[0013] The vertically suspended steel frame is a planar steel frame corresponding to the main beam and arranged at intervals along the transverse direction of the roof main steel structure, including suspenders. The top ends of the suspenders are fixedly connected to the main beam. The arc formed by the bottom ends of each suspender fits the bending radian of the double-curved shape ceiling at its corresponding position.

[0014] The main keel for adjustment along the board direction is composed of each keel segment. The two ends of the keel segment are correspondingly arranged at the bottom ends of adjacent two suspenders. The two ends of the adjacent keel segments and the bottom ends of the suspenders are adjustably connected through the keel attitude adjustment component.

[0016] The ceiling hanging adjustment component is longitudinally arranged corresponding to the hanging secondary keel and transversely arranged corresponding to the ceiling board segment. The top of the ceiling hanging adjustment component is buckled on the corresponding hanging secondary keel.

[0017] The arcs formed by connecting the bottom ends of each ceiling hanging and adjusting component fit the bending curvature of the hyperbolic-shaped ceiling at its corresponding position, and the bottom of the ceiling hanging and adjusting component is adjustably connected to the corresponding ceiling board segment.

[0018] The ceiling board segments altogether include four first ceiling board segments, second ceiling board segments, third ceiling board segments and fourth ceiling board segments which are arranged with their heads and tails staggered.

[0019] The hanging steel frame further includes a bottom bar and diagonal braces. The suspension rods are arranged at intervals along the bottom arc surface of the main beam. The bottom bar successively connects the bottoms of adjacent suspension rods, and the diagonal braces are obliquely and fixedly connected between adjacent suspension rods and above the bottom bar.

[0020] The main beam is an H-shaped steel beam, including a lower flange plate and a web. There are two C-shaped hoop members symmetrically arranged on the left and right on the main beam. The two C-shaped hoop members are buckled on the upper surfaces of the lower flange plates on both sides of the web and welded. Vertically adjacent connecting edges are symmetrically arranged at the bottom ends of the C-shaped hoop members. The suspension rod is closely attached to the outside of one of the connecting edges and is anchored by a main beam connecting bolt.

[0021] The conversion layer structure further includes a board end component. The board end component includes a hanging keel and a butt joint beam. The hanging keel is arranged at the splicing position of adjacent ceiling board segments. The top of the hanging keel is adjustably connected to the keel segment. The butt joint beam is arranged horizontally and fixedly connected to the side walls of adjacent hanging keels and at the staggered splicing position of the corresponding ceiling board segments. The end parts of adjacent ceiling board segments are respectively lapped on the butt joint beams on both sides of the hanging keel. The exposed position of the outer periphery of the hanging keel below the butt joint beam is covered by a U-shaped outer wrapping board. The U-shaped outer wrapping board is made of the same material as the ceiling board segment. The U-shaped outer wrapping board closes the staggered splicing joint between the ceiling board segments.

[0022] The hanging keel includes a hanging insertion plate and a keel body. Two vertically parallel adjusting plate oblong holes are opened at the top of the hanging insertion plate. At the corresponding position of the keel segment, a main keel hanging connection round hole is opened.

The adjusting plate adjusting bolt adjusts the vertical height position of the hanging insertion plate in the adjusting plate oblong hole.

[0023] Two vertically spaced hanging connection round holes are opened at the bottom of the hanging insertion plate. The keel body is a C-shaped steel, including a hanging keel back plate and hanging keel side plates. A vertically arranged keel body oblong hole is opened at the top of the hanging keel back plate. The bottom of the hanging insertion plate is closely attached to the top of the hanging keel back plate. The hanging connection round holes are all aligned with the keel body oblong hole and are anchored by two keel body adjusting bolts.

[0024] The suspension rod is made of angle steel and includes two suspension rod limb plates. The keel attitude adjustment assembly includes an adjustable conversion angle piece, a central shaft piece, and an adjustable insertion plate. The adjustable conversion angle piece includes a vertical conversion limb plate and a horizontal conversion limb plate. The vertical conversion limb plate is adjustably connected to the suspension rod limb plate through vertical conversion limb bolts.

[0026] A central shaft piece connection hole is opened in the center of the horizontal conversion limb plate. The central shaft piece includes a central shaft screw, a central shaft sleeve, and sleeve wing plates. The sleeve wing plates are symmetrically welded to both sides of the central shaft sleeve. The top end of the central shaft screw passes through the central shaft piece connection hole and is respectively anchored on both sides by nuts. The bottom end of the central shaft screw passes through the central shaft sleeve and is respectively anchored on both ends by nuts. Two bolt connection holes are opened on each sleeve wing plate, namely a central shaft piece round hole close to the central shaft sleeve and a central shaft piece arc-shaped long round hole far from the central shaft sleeve.

[0027] The keel section is a C-shaped steel and includes a main keel back plate and a main keel side plate. Two upper and lower keel connection round holes are opened on the main keel back plate.

The other end of the adjustable insertion plate is closely attached to the main keel back plate at the end of the keel section. The other end of the adjustable insertion plate is respectively provided with two parallel insertion plate long round holes corresponding to the keel connection round holes, and respectively passes through the main keel spacing adjustment bolts and is anchored;

[0029] The conversion angle piece swing adjustment bolt adjusts the swing angle of the adjustable conversion angle piece in the conversion angle piece arc-shaped long round hole, and then drives the central shaft piece to adjust the rotation angle of the keel section around the horizontal axis in the cross-section.

[0030] The relative anchoring position of the central shaft sleeve and the central shaft screw determines the rotation position of the sleeve wing plate, and then drives the central shaft piece to adjust the rotation angle of the keel section around the vertical axis in the cross-section.

[0031] The central shaft piece swing adjustment bolt adjusts the up and down warping angle of the keel section in the cross-section in the central shaft piece arc-shaped long round hole.

[0032] The main keel spacing adjustment bolts adjust the distance between adjacent keel sections in the insertion plate long round holes.

[0033] The hanging secondary keel and the keel section are fixedly connected through the main and secondary keel connectors. The hanging secondary keel is a C-shaped steel with the same size as the keel section, including a secondary keel back plate and a secondary keel side plate. The main and secondary keel connectors are angle pieces. The height of the angle piece is not greater than the distance between the main keel side plates and the distance between the secondary keel side plates.

The main keel connecting limb plate is closely attached to the main keel back plate and is connected through main keel connecting bolts. The secondary keel connecting limb plate is closely attached to the secondary keel back plate and is connected through secondary keel connecting bolts.

[0034] The ceiling hanging adjustment assembly includes a hoop main board, a hoop back board, a ceiling height adjustment piece, and a ceiling warping adjustment piece. The hoop main board is Ω-shaped. The hoop main board and the hoop back board enclose the hanging secondary keel on all sides. The top and bottom of the hoop back board are respectively fixedly connected to the two leg plates of the hoop main board through hoop bolts. The bottom of the hoop back board extends downward and is provided with a back board round hole and a back board arc-shaped long round hole up and down.

[0035] The ceiling height adjustment piece is an angle piece, including a height parallel adjustment limb plate and a height vertical adjustment limb plate. A group of vertical parallel plate adjustment long round holes and a group of vertical vertical plate adjustment long round holes are respectively opened on the height parallel adjustment limb plate and the height vertical adjustment limb plate in a left-right corresponding manner. The height parallel adjustment limb plate is closely attached to the back side of the hoop back board. The bottom hoop bolt does not pass through the parallel plate adjustment long round hole or passes through the parallel plate adjustment long round hole to anchor the hoop back board and the height parallel adjustment limb plate.

[0037] The hoop bolts, the back board fixing bolts, and the ceiling swing adjustment bolts adjust the installation height of the ceiling board by selecting the anchored parallel plate adjustment long round holes and the anchoring positions in the parallel plate adjustment long round holes. The ceiling swing adjustment bolts also adjust the swing angle of the ceiling height adjustment piece in the back board arc-shaped long round hole, thereby driving the adjustment of the left-right fluctuation angle within the cross-section of the ceiling board section, that is, adjusting the width of the board seam of the ceiling board section.

[0038] The warping adjustment piece fixing bolt and the ceiling warping adjustment bolt are vertically limited within the same vertical plate adjustment long round hole. The ceiling warping adjustment bolt adjusts the swing angle of the ceiling warping adjustment piece in the parallel plate adjustment long round hole, thereby driving the adjustment of the up-and-down warping angle along the board direction within the cross-section of the ceiling board section.

[0039] The arc formed by the connection lines of each ceiling warping adjustment member fits the bending radian of the hyperbolic-shaped ceiling at its location.

The top surface of the inner support parallel limb plates closely adheres to the bottom surface of the warping vertical connecting limb plates. Inner support connection holes corresponding to the ceiling inner support connection holes are provided on the inner support parallel limb plates. The inner support connection holes are aligned with the ceiling inner support connection holes and are anchored through inner support connection bolts. The top surfaces of the inner support parallel limb plates at both ends of the inner support angle member closely adhere to the bottom surfaces of the flanging limb plates on the bent edge plates and are anchored through anchor nails.

[0042] A construction method for an adjustment and installation system of a hyperbolic-shaped single-curved arc ceiling, and the construction steps are as follows:

[0043] Step 1, deepening the design of the ceiling structure: Establish a BIM model of the overall hyperbolic-shaped ceiling. In the model, design the hyperbolic-shaped ceiling as a group of ceiling boards that are single-curved and convex outward vertically. The width of each ceiling board is the same. The board joints between adjacent ceiling boards are of variable width. The ceiling board sections are set in segments with a substitute curve for the curve along the board direction. Determine the processing quantity, length of each ceiling board section and the size of each board joint in the model.

[0044] Step 2, deepening the design of the installation points: Scan the main steel structure of the roof that has been constructed, collect information and then perform BIM modeling to form a point position model. Carry out data collaboration with the BIM model of the hyperbolic-shaped ceiling in Step 1. In the point position model, preview the installation points of each vertical hanging steel frame, the main keel for adjustment along the board direction, the hanging secondary keel, the keel attitude adjustment component and the ceiling hanging adjustment component, and determine the quantity, size and installation points of each component.

[0045] Step 3, constructing the vertical hanging steel frame: Install according to the installation points of the vertical hanging steel frame determined in Step 2. Pre-install the keel attitude adjustment component at the bottom of the suspender. Lift the vertical hanging steel frame as a whole. The top end of the suspender is fixedly connected to the main beam. After the installation is completed, scan the bottom end of the suspender, collect information and then perform BIM modeling, compare it with the preset point position model in Step 2 and then make adjustments to ensure that the arc formed by the connection lines of the bottom ends of each suspender fits the bending radian of the hyperbolic-shaped ceiling at its location.

[0046] Step 4: Install the main keel for adjusting the board direction: Install the main keel for adjusting the board direction according to the installation points determined in step 2, that is, lift the keel section, and then connect the ends to the corresponding keel posture adjustment components respectively;

[0047] Step 5: Adjust the keel posture adjustment components:

[0048] The swing adjustment bolt of the conversion angle piece adjusts the swing angle of the adjustable conversion angle piece in the arc-shaped oblong hole of the conversion angle piece, thereby driving the central axis piece to adjust the rotation angle around the horizontal axis in the cross section of the keel section.

[0049] The relative anchoring position of the central axis sleeve and the central axis screw determines the rotation position of the sleeve wing plate, which in turn drives the central axis to adjust the rotation angle around the vertical axis in the cross section of the keel section.

[0050] The central axis swing adjustment bolt is in the arc-shaped oblong hole of the central axis to adjust the up and down warping angle of the cross section of the keel section.

[0051] The keel spacing adjustment bolt adjusts the distance between adjacent keel sections in the oblong hole of the plug plate.

[0052] The four adjustments are made to keep the keel section and the installation point determined in step 2 within the installation allowable error;

[0053] Step 6: construct and hang the secondary keel: pre-install the ceiling hanging adjustment component on the hanging secondary keel according to the installation point determined in step 2, then hoist the whole, and fix the two ends of the hanging secondary keel to the corresponding keel segments according to the installation point determined in step 2;

[0054] Step 7, constructing the board end assembly: according to the segmented position of the ceiling board segment determined in step 2, the top of the board end assembly is adjustably connected to the corresponding keel segment position;

[0055] Step 8, constructing the ceiling panel segment: between adjacent panel end components, hoist the corresponding ceiling panel segment, overlap the end of the ceiling panel segment on the panel end component, and determine the end position of the ceiling panel segment according to the installation point determined in step 2; then connect the ceiling panel segment with the corresponding ceiling hanging adjustment component;

[0056] Step nine, adjust the ceiling hanging adjustment components: scan the positions of the bottom ends and the board end components of the ceiling hanging adjustment components, collect information and perform BIM modeling, compare with the point model preset in step two, and then adjust to ensure that the arc formed by the bottom connection line of each ceiling hanging adjustment component fits the curvature of the hyperbolic ceiling at its location;

[0057] The adjustment process is as follows: The hoop bolts, the backplate fixing bolts, and the ceiling swing adjustment bolts adjust the installation height of the ceiling panel section by selecting the parallel plate adjustment oblong holes for anchoring and the anchoring positions within the parallel plate adjustment oblong holes.

[0058] The ceiling swing adjustment bolts adjust the swing angle of the ceiling height adjustment member within the arc-shaped oblong hole of the backplate, thereby driving the left and right fluctuation angles within the cross-section of the adjusted ceiling panel section, that is, adjusting the width of the panel joints of the ceiling panel section.

[0059] The ceiling warping adjustment bolts adjust the swing angle of the ceiling warping adjustment member within the parallel plate adjustment oblong hole, thereby driving the up and down warping angles along the panel direction within the cross-section of the adjusted ceiling panel section;

[0060] The three adjustments are coordinated until the overall visual appearance of the inner arc surfaces of each ceiling panel is smooth and flat without obvious warping and undulation;

[0061] Step ten, seal each ceiling panel section: Construct the U-shaped outer cladding plate to seal between each ceiling panel section, and the double-curved shaped ceiling installation is completed.

[0062] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0063] First, compared with the "equal joint but unequal plate" design in the installation of the existing double-curved ceiling, the present invention proposes a new ceiling installation system and its construction method, that is, adopting the method of "equal plate but unequal joint". The width of the ceiling panel is a fixed value. The double-curved surface is adjusted singly by controlling the attitude of the ceiling panel and the width of the panel joints between adjacent ceiling panels. With this new solution, the "decorative curved surface" of the BIM model of the new solution completely coincides with that of the original BIM model. In the curvature analysis, there is a tolerance of 1 mm for some strips in the long side direction, there is no tolerance in the length direction for most of the plates, and the tolerance in the short side direction can be ignored. Only the jointing method has changed, and there is no obvious difference in the visual effect. After fixing the plate width, there is no need to perform variable cross-section welding processing on the double-curved ceiling panel. The difficulty of plate forming processing is small, which ensures the problem of the overall double-curved surface curvature of the arc-shaped double-curved ceiling. At the same time, the plates can be mass-produced, greatly improving the construction efficiency and ensuring the construction quality.

[0064] Second, the adjustment of the ceiling board in the present invention is a multi-component adjustment. A conversion layer structure with keels is designed. The secondary keels are installed on the main keels, and then the ceiling boards are hung on the secondary keels. The single control at the bottom end of the traditional suspender is converted into the control of the main and secondary keels. A keel attitude adjustment component is designed to control the attitudes of the bottom of the suspender and the main keel, and a ceiling hanging adjustment component is designed to control the attitude and the board joints of the ceiling board section. The present invention realizes the control of multiple installation positions of the ceiling board section, can finely adjust the ceiling board section. Even if there are large errors in the installation of the suspenders, the fine installation of the ceiling board can still be achieved through the conversion layer structure, meeting the installation accuracy. At the same time, the angles, curvatures of the ceiling board section and the width of the board joints between adjacent boards are adjusted to ensure the double-curved surface structure of the arc-shaped ceiling board, and the arc surface of the arc-shaped ceiling board is smooth when observed from multiple angles, achieving an aesthetic visual effect.

[0065] Third, the present invention uniformly adopts a design of staggered heights for the ceiling boards in segments. At the segmented positions, board end components are designed, and the staggered positions are enclosed for closure. The attitudes of each ceiling board section are controlled and finally the entire ceiling board strip is fitted. This segmented installation method simplifies the overall installation difficulty of the ceiling board strip on the one hand, reduces the stress on the bearing capacity of the main steel structure of the roof, and on the other hand, the board end components provide space for position adjustment at the ends of the ceiling board sections, and at the same time become the root keels for closed installation, reducing the installation difficulty and ensuring the visual effect.

[0066] Fourth, the material of the ceiling board in the present invention is changed from aluminum single plates to open aluminum profiles. The thickness of the aluminum profiles remains unchanged, and the height of the aluminum profiles becomes higher. The new profile solution is more conducive to roll forming of the arc. The reverse flanging can not only strengthen the roll arc strength, but also be used as a connecting edge for accessories. The increase in the flanging height also makes the three-dimensional sense of the appearance effect stronger. BRIEF DESCRIPTION OF THE DRAWINGS

[0135] The construction method of the adjustable installation system for this hyperbolic single-curved ceiling is as follows:

[0136] Step 1, deepening the design of the ceiling structure: Establish a BIM model of the overall hyperbolic ceiling. In the model, design the hyperbolic ceiling into a group of ceiling boards that are single-curved and convex outward vertically. The width of each ceiling board is the same, and the board joints between adjacent ceiling boards are of variable width. Set up ceiling board segments 2 in a segmented manner with a substitute curve for the curve along the board direction. Determine the processing quantity, length of each ceiling board segment 2, and the size of each board joint in the model.

[0137] Step 2, deepening the design of the installation points: Scan the main steel structure of the roof that has been constructed. After collecting information, conduct BIM modeling to form a point model, and perform data collaboration with the BIM model of the hyperbolic ceiling in Step 1. In the point model, pre-act the installation points of each vertical hanging steel frame 4, the main keel adjusted along the board direction, the secondary keel 6 connected by hanging, the keel attitude adjustment component 7, and the ceiling hanging and adjustment component 8, and determine the quantity, size, and installation points of each component.

[0138] Step 3, constructing the vertical hanging steel frame: Install according to the installation points of the vertical hanging steel frame 4 determined in Step 2. Pre-install the keel attitude adjustment component 7 at the bottom of the suspender 41. Hoist the vertical hanging steel frame 4 as a whole. Fix the top end of the suspender 41 to the main beam 1. After installation, scan the bottom end of the suspender 41, conduct BIM modeling after collecting information, compare it with the pre-set point model in Step 2, and then make adjustments to ensure that the arc formed by the bottom ends of each suspender 41 fits the bending arc of the hyperbolic ceiling at its location.

[0139] Step 4, constructing the main keel adjusted along the board direction: Install the main keel adjusted along the board direction according to the installation points determined in Step 2, that is, hoist the keel section 5, and then connect the ends to the corresponding keel attitude adjustment components 7 respectively.

[0140] Step 5, adjusting the keel attitude adjustment component:

[0141] The swing adjustment bolt 74 of the conversion angle piece adjusts the swing angle of the adjustable conversion angle piece 71 in the arc-shaped long circular hole 713 of the conversion angle piece, thereby driving the central shaft piece 72 to adjust the rotation angle of the keel section 5 around the horizontal axis within the cross-section,

[0142] The relative anchoring position of the middle shaft sleeve 722 and the middle shaft screw 721 determines the rotation position of the sleeve wing plate 723, thereby driving the central shaft piece 72 to adjust the rotation angle of the keel section 5 around the vertical axis within the cross-section,

[0143] The swing adjustment bolt 77 of the central shaft piece adjusts the up and down warping angle of the keel section 5 within the cross-section in the arc-shaped long circular hole 725 of the central shaft piece,

[0144] The keel spacing adjustment bolt 78 adjusts the distance between adjacent keel segments 5 in the slotted plate oblong hole 732.

[0145] The four adjustments are coordinated to keep the keel section 5 and the installation point determined in step 2 within the installation allowable error.

[0146] Step six, construct the secondary keel: pre-install the ceiling hanging adjustment component 8 on the secondary keel according to the installation point determined in step two, then lift it as a whole, and fix the two ends of the secondary keel to the corresponding keel segments 5 according to the installation point determined in step two.

[0147] Step seven, constructing the board end assembly: according to the segmented position of the ceiling board segment 2 determined in step two, the top of the board end assembly 9 is adjustably connected to the corresponding keel segment 5 position.

[0148] Step eight, construct the ceiling panel segment: between adjacent panel end components, lift the corresponding ceiling panel segment 2, overlap the end of the ceiling panel segment on the panel end component 9, and determine the end position of the ceiling panel segment according to the installation point determined in step two; then connect the ceiling panel segment 2 to the corresponding ceiling hanging adjustment component 8.

[0149] Step 9: Adjust the ceiling mounting assembly:

[0150] Rough modeling adjustment: Scan the positions of the bottom end and the board end components of the ceiling hanging adjustment component 8, collect information, and perform BIM modeling, compare it with the point model preset in step 2, and then make adjustments to ensure that the arc formed by the bottom connection line of each ceiling hanging adjustment component 8 fits the curvature of the hyperbolic ceiling at its location;

[0151] The fine adjustment process of the adjustment member is as follows: the clamp bolt 85, the back plate fixing bolt 86 and the ceiling swing adjustment bolt 87 adjust the installation height of the ceiling plate segment 2 by selecting the parallel plate adjustment oblong hole 833 for anchoring and the anchoring position in the parallel plate adjustment oblong hole 833;

[0152] The ceiling swing adjustment bolt 87 adjusts the swing angle of the ceiling height adjustment member 83 in the arc-shaped oblong hole 822 of the back plate, thereby driving the left and right fluctuation angle in the cross section of the ceiling plate section 2 to adjust the plate seam width of the ceiling plate section 2;

[0153] The ceiling warping adjustment bolt 88 adjusts the swing angle of the ceiling warping adjustment member 84 in the parallel plate adjustment oblong hole 833, thereby driving the adjustment of the upward and downward warping angle of the ceiling plate section 2 in the cross section;

[0154] The three adjustments are made until the inner curved surface of each ceiling panel looks smooth and flat as a whole without obvious warping and fluctuations.

[0155] Step ten, seal each ceiling panel section: Construct the U-shaped outer cladding plate 20 to seal between each ceiling panel section 2, and the installation of the hyperbolic-shaped ceiling is completed.
