Description

Technical Field

[0001] This invention relates to the field of ceiling construction, and in particular to a construction method and maintenance method for complex ceiling decorations. Background Technology

[0002] Currently, ceiling designs are becoming increasingly complex, encompassing various forms, such as the widely used multi-layered circular tube ceiling structure (combinations of two, three, or even four or more layers of circular tubes). This type of ceiling typically employs a staggered arrangement of adjacent layers with varying net spacing to create an intricate and layered decorative effect. However, in actual installation, due to the complexity of the structure and limitations of high-altitude work conditions, it is often difficult to guarantee the flatness of each layer of circular tubes and the overall assembly accuracy. This results in a significant deviation between the final product and the design expectations, severely impacting the quality of the decoration.

[0003] Therefore, existing technologies suffer from problems such as high installation difficulty and insufficient precision control, and there is an urgent need for a technical solution that can improve installation efficiency and ensure the assembly precision of complex ceiling decorations.

In each ceiling unit, 70%-80% of the pipe connection points are fixed by welding, and 20%-30% of the pipe connection points are connected by spring clips. The spring clip connection points are set close to the access panel. S4: Determine the installation positions of the upper, middle, and lower ceiling units based on the cell layout; S5: Sequentially lift and install the i-th upper ceiling unit, the i-th middle ceiling unit, and the i-th lower ceiling unit, i=1, 2, ..., n-1; S6: A clamp-type connector is provided at the end of the i-th middle layer ceiling unit. The clamp-type connector includes an integrally formed first area and two second areas. The second area is located above the first area. The first area forms a pipe support channel, and the second area forms a pipe support hole. The bottom surfaces of the pipe support channel and the pipe support hole are both arc-shaped. The two second areas are spaced apart, and the two second areas are provided with at least two locking holes respectively. The pipes of the i-th middle-layer suspended ceiling unit are inserted into the pipe support channel, and the pipes of the i-th upper-layer suspended ceiling unit are placed in the pipe support hole. A clamp-type connector is installed at the end of the i-th lower ceiling unit to extend the pipe of the i-th lower ceiling unit into the pipe support channel, and the pipe of the i-th middle ceiling unit is placed in the pipe support hole. S7: Sequentially lift and install the (i+1)th upper ceiling unit, the (i+1)th middle ceiling unit, and the (i+1)th lower ceiling unit, i=1, 2, ..., n-1; At the joint of the middle-level ceiling unit, the pipe of the (i+1)th middle-level ceiling unit is inserted into the pipe channel; At the splicing point of the lower ceiling unit, the pipe of the (i+1)th lower ceiling unit is inserted into the pipe channel; S8: The pipe channel is locked by at least two locking elements passing through the corresponding two locking holes, thereby connecting the i-th middle-layer ceiling unit and the i+1-th middle-layer ceiling unit, and connecting the i-th lower-layer ceiling unit and the i+1-th lower-layer ceiling unit. S9: Connect the i-th upper ceiling unit and the (i+1)-th upper ceiling unit using clamps; S10: Repeat steps S5-S9 until the installation of all upper ceiling units, all middle ceiling units, and all lower ceiling units is completed.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The construction method for complex ceiling decoration described in this invention involves first assembling each ceiling unit on the ground / countertop. 70%-80% of the pipe connection points in each unit are fixed by welding, ensuring good flatness. This allows the pipes in each unit to be arranged horizontally and vertically after installation, achieving a complex and visually appealing installation effect. High flatness also improves installation accuracy and facilitates alignment between adjacent units, increasing assembly efficiency. The remaining 20%-30% of pipe connection points use spring clips, positioned near the access panel. This not only facilitates maintenance of the complex ceiling decoration but also provides flexibility for adjusting the connection position, further improving assembly accuracy. The combination of welding and spring clips in the pipe connection points of the ceiling units in this invention provides sufficient rigidity while also offering flexibility and adjustability, thus enhancing the assembly accuracy of complex ceiling decorations.

[0021] Furthermore, the present invention connects two adjacent ceiling units by setting clamp-type connectors at the ends of the ceiling units. On the one hand, the connection between two adjacent ceiling units can be easily realized through the pipe channel. On the other hand, the interference between ceiling units can be reduced through the pipe hole, thereby reducing the difficulty of assembling two adjacent ceiling units at high altitude and realizing the rapid assembly of complex ceiling decorations.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0036] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer," etc., used in the description of specific embodiments of the present invention to indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0037] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0038] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0039] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0040] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to connection methods commonly used in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0041] Example 1 For double-layer suspended ceiling structures, this embodiment provides a construction method for complex ceiling decoration, including the following steps: S1: Divide the upper ceiling 4 into n upper ceiling units 41, and divide the lower ceiling 5 into n lower ceiling units 51. In the preferred embodiment, each upper ceiling unit 41 is 6m × 6m in size, and each lower ceiling unit 51 is 6m × 6m in size. In this way, the size and weight of each ceiling unit are more suitable, which can improve the assembly efficiency, reduce the number of hoisting operations, and reduce the hoisting difficulty, thereby facilitating the rapid assembly of complex ceiling decorations.

[0042] S2: Arrange the upper ceiling unit 41 and the lower ceiling unit 51 into cell layouts, and mark the grid lines on the ground. For example, before assembly, use CAD software to arrange the 6m×6m cell layout, and then the workers mark the grid lines on the ground according to the layout diagram.

[0043] S3: Assemble the upper ceiling unit 41 and the lower ceiling unit 51 according to the cell layout. In each ceiling unit, 70%-80% of the pipe connections are fixed by welding, and 20%-30% of the pipe connections are connected by spring clips 7, with the spring clip connections located near the access panel. For example... Figure 1 As shown, 70%-80% of the pipe connection points in the upper ceiling unit 41 are fixed by welding, for example, stainless steel pipes are fixed by argon arc welding according to the cell layout. 20%-30% of the pipe connection points in the upper ceiling unit 41 are connected by spring clips 7. For example... Figures 9-10As shown, spring clips 7 are used to connect the upper and lower pipes of the pipe connection point of the upper ceiling unit 41, and spring clips 7 are used to connect the upper and lower pipes of the pipe connection point of the lower ceiling unit 51.

[0044] In one of the optional solutions, the method for determining the spring clip connection points is as follows: First, establish a mechanical and electrical (MEP) BIM model. Use the locations of the MEP equipment in the MEP BIM model to determine the access panel locations. Typically, areas with a high density of MEP equipment are designated as access panel locations. Then, set up spring clip connection points near the access panels. MEP equipment includes air ducts, water pipes, lighting fixtures, and fire protection facilities, etc.

[0045] S4: Determine the hoisting positions of the upper ceiling unit 41 and the lower ceiling unit 51 based on the cell layout. In the preferred embodiment, the hoisting positions of the upper ceiling unit 41 and the lower ceiling unit 51 are staggered on the horizontal plane. After the hoisting points are staggered, the force is more dispersed, reducing stress concentration on the hangers and deformation. This helps to improve the hoisting accuracy of the ceiling units, improve the flatness of the ceiling units, and reduce the assembly difficulty between the ceiling units.

[0046] S5: Sequentially lift and install the i-th upper ceiling unit 41 and the i-th lower ceiling unit 51, i=1,2,...,n-1, and connect the i-th upper ceiling unit 41 and the i-th lower ceiling unit 51 with threaded rods and pipe clamps.

[0047] In the preferred scheme, such as Figure 2 As shown, the upper ceiling unit 41 and the lower ceiling unit 51 are staggered on the horizontal plane. This not only makes the arrangement more aesthetically pleasing, but also distributes the stress more evenly, reducing stress concentration on the hangers and deformation. This helps improve the installation accuracy and flatness of the ceiling units, as well as the assembly difficulty between the ceiling units.

[0048] The staggered arrangement of the upper ceiling unit 41 and the lower ceiling unit 51 on the horizontal plane means that the upper ceiling unit 41 and the lower ceiling unit 51 are roughly the same size, but are staggered in both the horizontal and vertical directions. For example, the horizontal bars of the upper ceiling unit 41 are arranged at 0m, 0.4m, 0.8m, 1.2m, 1.6m... and the vertical bars of the upper ceiling unit 41 are arranged at 0m, 0.4m, 0.8m, 1.2m, 1.6m... and the horizontal bars of the lower ceiling unit 51 are arranged at 0.2m, 0.6m, 1.0m, 1.4m, 1.8m... and the vertical bars of the lower ceiling unit 51 are arranged at 0.2m, 0.6m, 1.0m, 1.4m, 1.8m...

[0049] S6: As Figures 4-7As shown, the clamp-type connection structure is used to connect two adjacent upper ceiling units 41 and lower ceiling units 51. The clamp-type connection structure includes a clamp-type connector 1 and at least two locking components 2. The at least two locking components 2 are used to lock the clamp-type connector 1.

[0050] The clamp-type connector 1 includes an integrally formed first region 12 and two second regions 11. The second regions 11 are located above the first region 12, and the two second regions 11 are spaced apart. In a preferred embodiment, the first region 12 and the two second regions 11 are formed by bending steel plates. In a further preferred embodiment, the first region 12 is a tubular structure with an opening at the top, and the two second regions 11 are both flat structures, with each of the two second regions 11 connected to the upper opening of the tubular structure.

[0051] The first area 12 has a pipe-bearing channel 13 for connecting the round pipe in the lower ceiling unit 51. The second area 11 has a pipe-supporting hole 14 for supporting the round pipe in the upper ceiling unit 41. The bottom surfaces of the pipe-bearing channel 13 and the pipe-supporting hole 14 are both arc-shaped. In a preferred embodiment, the diameter of the arc-shaped hole matches the outer diameter of the round pipe in the upper ceiling unit 41 and the lower ceiling unit 51. For example, the diameter of the arc-shaped hole is equal to or slightly larger than the outer diameter of the round pipe in the upper ceiling unit 41 and the lower ceiling unit 51, thereby more stably limiting the position of the round pipe in the ceiling unit.

[0052] In an optional embodiment, the pipe channel 13 is a circular channel, and the inner diameter of the circular channel matches the outer diameter of the circular pipe in the lower ceiling unit 51. For example, the inner diameter of the circular channel is equal to or slightly larger than the outer diameter of the circular pipe in the lower ceiling unit 51, thereby enabling more stable positioning of the circular pipe in the lower ceiling unit 51.

[0053] The pipe-supporting hole 14 has a top-opening structure, a rounded bottom surface, and flat sides. The diameter of the bottom surface of the pipe-supporting hole 14 matches the outer diameter of the circular pipe in the upper ceiling unit 41, and the distance between the two sides of the pipe-supporting hole 14 also matches the outer diameter of the circular pipe in the upper ceiling unit 41. For example, the diameter of the bottom surface of the pipe-supporting hole 14 is equal to or slightly larger than the outer diameter of the circular pipe in the upper ceiling unit 41, the diameter of the distance between the two sides of the pipe-supporting hole 14 is equal to or slightly larger than the outer diameter of the circular pipe in the upper ceiling unit 41, and the distance between the two sides of the pipe-supporting hole 14 should be greater than the diameter of the bottom surface of the pipe-supporting hole 14, thereby facilitating the entry of the circular pipe in the upper ceiling unit 41 into the pipe-supporting hole 14.

[0054] The connecting direction of the pipe support hole 14 is perpendicular to the connecting direction of the pipe support channel 13. For example, if the connecting direction of the pipe support channel 13 is longitudinal, the connecting direction of the pipe support hole 14 is transverse. The circular pipes in each ceiling unit include transversely arranged horizontal pipes and longitudinally arranged vertical pipes. If the connection between two adjacent upper ceiling units 41 and lower ceiling units 51 is longitudinally connected, there may be interference between the pipes in the upper ceiling unit 41 and the clamp-type connector 1. By setting the pipe support hole 14, the pipes in the upper ceiling unit 41 can pass through the pipe support hole 14, thereby avoiding installation difficulties caused by interference between the pipes in the upper ceiling unit 41 and the clamp-type connector 1.

[0055] Each of the two second zones 11 is provided with at least two locking holes 15, and at least two locking members 2 pass through the corresponding two locking holes 15 and are locked. The locking holes 15 may be through holes, and the locking holes 15 of the two second zones 11 are correspondingly provided, thereby facilitating the locking members 2 to pass through the corresponding two locking holes 15 and be locked. In a preferred embodiment, the number of locking holes 15 is 2-3, and the number of locking members 2 is 2-3. When the number of locking holes 15 is 2, the two locking holes 15 are located near the edge of the second zone 11; when the number of locking holes 15 is 3, the two locking holes 15 are located near the edge of the second zone 11, and the one locking hole 15 is located in the middle of the second zone 11.

[0056] In optional implementations, such as Figure 7 As shown, the locking component 2 may include a bolt 21 and a nut 22, wherein the bolt 21 passes through the locking hole 15 and is locked by the nut 22.

[0057] In an optional embodiment, the locking element 2 may be a screw or a pin, etc.

[0058] During construction, the clamp-type connector 1 is installed at the end of the i-th lower ceiling unit 51, the pipe of the i-th lower ceiling unit 51 is inserted into the pipe support channel 13, and the pipe of the i-th upper ceiling unit 41 is placed in the pipe support hole 14.

[0059] S7: As Figure 3 As shown, the (i+1)th upper ceiling unit 41 and the (i+1)th lower ceiling unit 51 are installed sequentially, i=1, 2, ..., n-1; the pipe of the (i+1)th lower ceiling unit 51 is inserted into the pipe channel 13.

[0060] S8: The pipe channel 13 is locked by at least two locking elements 2 passing through the corresponding two locking holes 15, thereby connecting the i-th lower ceiling unit 51 and the (i+1)-th lower ceiling unit 51.

[0061] S9: Connect the i-th upper ceiling unit 41 and the (i+1)-th upper ceiling unit 41 via clamp 3, as follows: Figure 8 The diagram shown is a structural schematic of clamp 3.

[0062] S10: Repeat steps S5-S9 until the installation of all upper ceiling units 41 and all lower ceiling units 51 is completed.

[0063] The construction method for complex ceiling decoration described in this invention involves first assembling each ceiling unit on the ground / countertop. 70%-80% of the pipe connection points in each unit are fixed by welding, ensuring good flatness. This allows the pipes in each unit to be arranged horizontally and vertically after installation, achieving a complex and visually appealing installation effect. High flatness also improves installation accuracy and facilitates alignment between adjacent units, increasing assembly efficiency. The remaining 20%-30% of pipe connection points use spring clips, positioned near the access panel. This not only facilitates maintenance of the complex ceiling decoration but also provides flexibility for adjusting the connection position, further improving assembly accuracy. The combination of welding and spring clips in the pipe connection points of the ceiling units in this invention provides sufficient rigidity while also offering flexibility and adjustability, thus enhancing the assembly accuracy of complex ceiling decorations.

[0064] Furthermore, the present invention connects two adjacent ceiling units by setting clamp-type connectors at the ends of the ceiling units. On the one hand, the connection between two adjacent ceiling units can be easily realized through the pipe channel. On the other hand, the interference between ceiling units can be reduced through the pipe hole, thereby reducing the difficulty of assembling two adjacent ceiling units at high altitude and realizing the rapid assembly of complex ceiling decorations.

[0065] Example 2 Based on Example 1, this example provides a construction method for complex ceiling decoration for a three-layer ceiling structure, including the following steps: S1: Divide the upper ceiling 4 into n upper ceiling units 41, the middle ceiling 6 into n middle ceiling units 61, and the lower ceiling 5 into n lower ceiling units 51. In the preferred embodiment, each upper ceiling unit 41 is 6m × 6m in size, each middle ceiling unit 61 is 6m × 6m in size, and each lower ceiling unit 51 is 6m × 6m in size. In this way, the size and weight of each ceiling unit are more suitable, which can improve assembly efficiency, reduce the number of hoisting operations, and reduce the hoisting difficulty, thereby facilitating the rapid assembly of complex ceiling decorations.

[0066] S2: Arrange the upper ceiling unit 41, middle ceiling unit 61, and lower ceiling unit 51 into individual cell layouts, and mark the grid lines on the ground. For example, before assembly, use CAD software to arrange the 6m×6m cell layout, and then the workers mark the grid lines on the ground according to the layout diagram.

[0067] S3: Assemble the upper ceiling unit 41, middle ceiling unit 61, and lower ceiling unit 51 according to the cell layout. In each ceiling unit, 70%-80% of the pipe connection points are fixed by welding (e.g., argon arc welding), and 20%-30% of the pipe connection points are connected by spring clips 7. The spring clip connection points are set close to the maintenance port.

[0068] Spring clips 7 are used to connect the upper and lower pipes of the pipe connection point of the upper ceiling unit 41, the upper and lower pipes of the pipe connection point of the middle ceiling unit 61, and the upper and lower pipes of the pipe connection point of the lower ceiling unit 51.

[0069] S4: Determine the installation positions of the upper ceiling unit 41, the middle ceiling unit 61, and the lower ceiling unit 51 based on the cell layout.

[0070] In the preferred embodiment, the hoisting positions of the upper ceiling unit 41, the middle ceiling unit 61, and the lower ceiling unit 51 are staggered on the horizontal plane. After the hoisting points are staggered, the force is more dispersed, reducing stress concentration on the hangers and deformation. This helps to improve the hoisting accuracy of the ceiling units, improve the flatness of the ceiling units, and reduce the difficulty of assembling the ceiling units.

[0071] In another preferred embodiment, while ensuring the flatness of the ceiling unit, the upper ceiling unit 41 and the lower ceiling unit 51 can share the same suspension point, thereby reducing the length of the suspension rod and saving construction costs.

[0072] S5: Sequentially lift and install the i-th upper ceiling unit 41, the i-th middle ceiling unit 61, and the i-th lower ceiling unit 51, i=1, 2, ..., n-1.

[0073] In the preferred scheme, such as Figure 11 As shown, the upper ceiling unit 41, the middle ceiling unit 61, and the lower ceiling unit 51 are staggered on the horizontal plane. This not only makes the arrangement more aesthetically pleasing, but also distributes the stress more evenly, reducing stress concentration on the hangers and deformation. This helps improve the installation accuracy and flatness of the ceiling units, as well as the assembly difficulty between the ceiling units.
