Description

Technical Field

[0001] The invention relates to the technical field of decorative ceiling construction, and in particular to an adjustment and installation system of a hyperbolic single-curved arc ceiling, a construction method thereof and a construction method thereof. Background Art

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

[0003] At present, for the interior ceiling panels with hyperbolic shapes, multiple hyperbolic arc panels are usually spliced ​​together. Since the size and shape of each hyperbolic arc panel to be spliced ​​are often different, it is necessary to import them into the modeling program in advance to fit the position, and then process them individually in the factory and then transport them to the site for positioning and installation, which is very cumbersome.

[0004] Therefore, the designer designed the hyperbolic interior ceiling panel to be formed by a group of single-curved aluminum strips as the base material. The space between the curved aluminum strips appears black under indoor light, so that the alternating single-curved aluminum strips and the space between the strips can not only form a hyperbolic shape, but also form a visually striped interior ceiling panel, eliminating the need for processing and on-site installation of the hyperbolic panels, and only the single-curved aluminum strips need to be processed and positioned.

[0005] In order to achieve the visual effect, the existing single-curved aluminum strip design adopts the method of equal seams and unequal plates, that is, the width of the seams between the strips remains unchanged, and the change of the entire hyperbolic surface is mainly adjusted by the width of the strips. Because the hyperbolic surface is generated by the Bezier curve, in order to ensure that the seams 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 the width of the top aluminum plate, that is, the strip shape after flattening is fan-shaped. However, the fan-shaped strip can only be realized by welding technology. Because the plate surface is narrow, the hot melt deformation and stress changes generated during the welding process are uncontrollable. The curvature of the final product cannot match the curvature in the BIM model, which ultimately affects the decorative effect.

[0006] At the same time, the keel posture adjustment is generally carried out through the connection node between the hanger and the back of the keel, with few adjustment dimensions and extremely inconvenient adjustment construction. After the hanger is installed, it is usually impossible to adjust the spatial position at a single point, resulting in the ceiling installation position being difficult to adjust once the hanger installation position has a large deviation. In addition, the traditional ceiling board is a single aluminum single board, which is not conducive to roller arc forming during processing. Therefore, there is an urgent need for an installation system and construction method of a single curved ceiling strip that avoids the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide an adjustment and installation system for a hyperbolic single-curved ceiling and a construction method thereof, in order to solve the technical problem of the complicated construction of multiple splicing of existing hyperbolic interior ceiling panels; and to solve the technical problem that the existing single-curved aluminum strip plate design adopts the method of equal seams and unequal plates, and when the fan-shaped strip plates are realized by welding, uncontrollable deformation and stress changes will be caused to the plate body, so that the curvature of the plate surface of the final product cannot reach the final design effect; and also to solve the technical problems that the traditional single-point spatial adjustment of the suspension rod is difficult and the processing of a single aluminum single plate is not conducive to roller arc forming.

[0008] To achieve the above object, the present invention adopts the following technical solution: A hyperbolic single-curved ceiling adjustment and installation system includes a main roof steel structure, a transfer layer structure and a hyperbolic ceiling.

The main steel structure of the roof is a hyperbolic grid structure, including a set of vertical single-curved convex main beams, which are arranged in rows and at intervals along the horizontal direction. The hyperbolic ceiling includes a group of vertically convex single-curved ceiling panels, which are arranged in rows with horizontal intervals. The width of each ceiling panel is the same, and the seams between adjacent ceiling panels are variable-width seams. The ceiling panels and the seams form an equal-plate unequal-seam state.

The hanger is close to the outer side of one of the connecting edges and is anchored through the main beam connecting bolts.

[0012] The conversion layer structure also includes a board end assembly, which includes a suspended keel and an abutment beam. The suspended keel is arranged at the splicing position of adjacent ceiling panel sections. The top of the suspended keel is adjustably connected to the keel section. The abutment beam is arranged in a transverse direction and fixedly connected to the side walls of the adjacent suspended keels, corresponding to the staggered splicing positions of the ceiling panel sections. The ends of the adjacent ceiling panel sections are respectively overlapped on the abutment beams on both sides of the suspended keel. The exposed peripheral position of the suspended keel below the abutment beam is covered by a U-shaped outer covering plate. The U-shaped outer covering plate is made of the same material as the ceiling panel section and closes the staggered splicing seams between the ceiling panel sections. The suspension keel includes a suspension plug plate and a keel body. Two vertically parallel oblong holes of the adjustment plate are opened on the top of the suspension plug plate. A main keel suspension connection circular hole is opened at the corresponding position of the keel section.

A central axis connecting hole is opened in the center of the horizontal conversion limb plate. The central axis includes a central axis screw, a central axis sleeve and a sleeve wing plate. The sleeve wing plates are welded symmetrically on both sides of the central axis sleeve. The top end of the central axis screw passes through the central axis connecting hole and is anchored by nuts on both sides. The bottom end of the central axis screw passes through the central axis sleeve and is anchored by nuts on both ends. Two bolt connection holes are opened on each sleeve wing plate, which are a central axis circular hole close to the central axis sleeve and an arc-shaped oblong hole of the central axis away from the central axis sleeve. The keel section is a C-shaped steel, and includes a main keel back plate and a main keel side plate. The main keel back plate is provided with two upper and lower keel connection circular holes. One end of the adjustable plug plate is provided with two adjustable plug plate circular holes corresponding to the central axis circular hole and the central axis arc-shaped oblong hole, and the central axis fixing bolt and the central axis swing adjustment bolt are passed through and anchored respectively. The other end of the adjustable plug plate is closely attached to the main keel back plate at the end of the keel section. The other end of the adjustable plug plate is provided with two parallel plug plate oblong holes corresponding to the keel connection circular holes, and the main keel spacing adjustment bolts are passed through and anchored respectively. 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. 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. 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. The keel spacing adjustment bolt is arranged in the oblong hole of the plug plate to adjust the distance between adjacent keel sections.

[0014] The hanging secondary keel is fixedly connected to the keel section through the primary and secondary keel connecting parts. 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 primary and secondary keel connecting parts are angle pieces. The height of the angle pieces is not greater than the distance between the main keel side plates and the distance between the secondary keel side plates.

The height parallel adjustment limb and the height vertical adjustment limb are respectively provided with a group of vertical parallel plate adjustment oblong holes and a group of vertical vertical plate adjustment oblong holes on the left and right. The height parallel adjustment limb is close to the back side of the clamp back plate. The clamp bolts at the bottom do not pass through the parallel plate adjustment oblong holes or pass through the parallel plate adjustment oblong holes to anchor the clamp back plate to the height parallel adjustment limb. The back plate circular hole and the back plate arc oblong hole are aligned with the same parallel plate adjustment oblong hole and pass through the back plate fixing bolts and the ceiling swing adjustment bolts respectively and anchored. The ceiling warping adjustment piece is an angle piece, including a warping parallel adjustment limb plate and a warping vertical connection limb plate.

The parallel limb arc-shaped long round holes and parallel limb round holes are aligned with the bottom vertical plate adjustment long round holes and pass through the ceiling warping adjustment bolts and the warping adjustment piece fixing bolts and anchored respectively. The clamp bolts, back plate fixing bolts and ceiling swing adjustment bolts adjust the installation height of the ceiling board by selecting the parallel plate adjustment oblong holes for anchoring and the anchoring position in the parallel plate adjustment oblong holes. The ceiling swing adjustment bolts also adjust the swing angle of the ceiling height adjustment piece in the arc-shaped oblong holes of the back plate, thereby driving the left and right fluctuation angles in the cross section of the ceiling board section, that is, adjusting the board seam width of the ceiling board section. The fixing bolt of the warping adjustment piece and the warping adjustment bolt of the ceiling are vertically limited in the same vertical plate adjustment oblong hole. The warping adjustment bolt of the ceiling adjusts the swing angle of the warping adjustment piece of the ceiling in the parallel plate adjustment oblong hole, thereby driving the upward and downward warping angle of the ceiling plate section. The arc formed by the connecting lines of each ceiling warping adjusting member fits the curvature of the hyperbolic ceiling at the position where the member is located.

[0016] The warped vertical connecting limbs are provided with ceiling support connection holes. The ceiling panel section is an open C-shaped groove aluminum material, including a main panel and bent side panels with both ends bent in the opposite direction toward the back side.

[0017] A construction method for an adjustable installation system of a hyperbolic single-curved ceiling, the construction steps are as follows: Step 1: In-depth design of the ceiling structure: Establish a BIM model of the overall hyperbolic ceiling. In the model, the hyperbolic ceiling is designed as a group of vertically convex single-curved ceiling panels. The width of each ceiling panel is the same, and the board seams between adjacent ceiling panels are variable widths. The ceiling panels are divided into sections along the board direction with folds instead of curves. The processing quantity and length of each ceiling panel segment and the size of each board seam are determined in the model. Step 2: In-depth design of installation points: Scan the completed main steel structure of the roof, collect information, and then perform BIM modeling to form a point model. Collaborate with the BIM model of the hyperbolic ceiling in step 1. In the point model, preview the installation points of each hanging steel frame, the main keel adjusted along the board, the secondary keel, the keel posture adjustment component, and the ceiling hanging adjustment component to determine the quantity, size, and installation point of each component. Step 3: construct the vertical hanging steel frame: install it according to the installation point of the vertical hanging steel frame determined in step 2, pre-install the keel posture adjustment component at the bottom of the hanger, lift the vertical hanging steel frame as a whole, and fix the top of the hanger with the main beam. After the installation is completed, scan the bottom of the hanger, collect information and perform BIM modeling, compare it with the preset point model in step 2, and then adjust it to ensure that the arc formed by the bottom connection line of each hanger fits the curvature of the hyperbolic ceiling at its location; 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; Step 5: Adjust the keel posture adjustment components: 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. 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. 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. The keel spacing adjustment bolt adjusts the distance between adjacent keel sections in the oblong hole of the plug plate. The four adjustments are made to keep the keel section and the installation point determined in step 2 within the installation allowable error; 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; 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; 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; 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; The adjustment process is as follows: the clamp bolts, back plate fixing bolts and ceiling swing adjustment bolts adjust the installation height of the ceiling plate section by selecting the parallel plate adjustment oblong holes for anchoring and the anchoring position in the parallel plate adjustment oblong holes. The ceiling swing adjustment bolt adjusts the swing angle of the ceiling height adjustment piece in the arc-shaped oblong hole of the back plate, thereby driving the left and right fluctuation angle in the cross section of the ceiling plate section to adjust the plate seam width of the ceiling plate section. The ceiling warping adjustment bolt adjusts the swing angle of the ceiling warping adjustment member in the parallel plate adjustment oblong hole, thereby driving the adjustment of the upward and downward warping angle of the ceiling plate section in the cross section; The three adjustments are coordinated until the inner curved surface of each ceiling panel looks smooth and flat without obvious warping and undulations; Step 10, seal each ceiling panel section: construct U-shaped outer panels to seal between each ceiling panel section, and the hyperbolic ceiling is installed.

[0018] Compared with the prior art, the present invention has the following characteristics and beneficial effects: 1. Compared with the existing "equal seams and unequal panels" design for the installation of hyperbolic ceilings, the present invention proposes a new ceiling installation system and its construction method, that is, adopting the "equal panels and unequal seams" method, the width of the ceiling panels is a fixed value, and the hyperbolic surface is adjusted by controlling the posture of the ceiling panels and the width of the panel seams between adjacent ceiling panels. The "decorative curved surface" of the new BIM model and the original BIM model using this method completely overlap, and some strips in the long side direction have a tolerance of 1mm in the curvature analysis, and most of the panels have no tolerance in the length direction, and the tolerance in the short side direction can be ignored. Only the seam splitting method has changed, and there is no obvious difference in visual effect. After the panel width is fixed, there is no need to perform variable cross-section welding processing on the hyperbolic ceiling panels, and the difficulty of panel forming processing is small, which ensures the overall hyperbolic curvature of the curved hyperbolic ceiling. At the same time, the panels can also be mass-produced, which greatly improves the construction efficiency and ensures the construction quality.

[0019] Second, the present invention uses multiple components to adjust the ceiling panels, designs a conversion layer structure with a keel, the secondary keel is installed on the main keel, and then the ceiling panel is hung on the secondary keel, converting the single control of the bottom end of the traditional hanger and the back side of the keel into the control of the primary and secondary keels, designs a keel posture adjustment component to control the posture of the bottom of the hanger and the main keel, and designs a ceiling hanging adjustment component to control the posture of the ceiling panel section and the board seam. The present invention realizes the control of multiple installation positions of the ceiling panel section, and can make fine adjustments to the ceiling panel section. Even if there is a large error in the installation of the hanger, the conversion layer structure can be used to achieve fine installation of the ceiling panel to meet the installation accuracy. At the same time, the angle, curvature of the ceiling panel section and the width of the board seam between adjacent panels are adjusted to ensure the hyperbolic structure of the curved ceiling panel, and realize that the curved surface of the curved ceiling panel is smooth when observed from multiple angles, achieving a beautiful visual effect.

[0020] 3. The present invention adopts a segmented height staggered design for the ceiling panels, designs board end components at the segmented positions, and closes and encloses the staggered positions to control the posture of each ceiling panel segment and finally fit the entire ceiling strip. On the one hand, this segmented installation method simplifies the overall installation difficulty of the ceiling strip and reduces the stress of the bearing capacity of the main steel structure of the roof. On the other hand, the board end components provide space for position adjustment for the ends of the ceiling panel segments and become a rooting keel for closed installation, thereby reducing the difficulty of installation and ensuring the visual effect.

[0021] 4. The material of the ceiling board of the present invention is changed from aluminum veneer to open aluminum profile. The thickness of the aluminum profile remains unchanged, and the height of the aluminum profile becomes higher. The new material scheme is more conducive to roller arc forming. The reverse folding edge can not only enhance the strength of the roller arc, but also can be used as an accessory connecting edge. The increase in the folding edge height also makes the appearance more three-dimensional. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] See Example Figure 2 As shown, an adjustable installation system for a hyperbolic single-curved ceiling includes a main steel structure of the roof, a transfer layer structure and a hyperbolic ceiling. The hyperbolic ceiling is adjustably connected to the main steel structure of the roof through the transfer layer structure.

[0051] The main steel structure of the roof is a hyperbolic grid structure, including a group of vertical single-curved arc-shaped outwardly convex main beams 1, and the main beams 1 are arranged in rows and at intervals along the horizontal direction.

[0052] See also Figure 1 As shown, the hyperbolic ceiling includes a group of vertically convex single-curved ceiling panels, which are arranged in rows and horizontally spaced apart. The width of each ceiling panel is the same. In this embodiment, the width of each panel is uniformly adjusted to 300 mm. The panel seam 3 between adjacent ceiling panels is a variable width seam, and the ceiling panels and the panel seam 3 form an equal panel and unequal seam state. Figure 2 As shown, each row of ceiling panels is composed of ceiling panel segments 2 arranged in sections along the panel direction and staggered in height, and each ceiling panel segment 2 is a single curved arc.

[0087] Step 9: Adjust the ceiling mounting assembly: 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; 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; 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; 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; 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.
