Description

Technical Field

[0001] This application relates to the field of ceiling construction, and particularly to a three-dimensional inclined surface shaped ceiling and its construction method. Background Art

[0002] Ceiling plays important roles in interior decoration such as covering beams, columns, pipelines, heat insulation, and sound insulation, and occupies an extremely important position in the interior space. To meet people's requirements for spatial art, the design of interior ceiling has been continuously innovated from traditional planar shapes to dome-shaped ceilings, concave-convex shaped ceilings, and three-dimensional shaped ceilings.

[0003] For the decoration project of a three-dimensional inclined surface shaped ceiling in a tall space, such as a super-high ceiling space, how to install it quickly, accurately, and safely has become a major problem for most projects. The traditional gypsum board ceiling construction technology is more suitable for planar ceiling design and cannot meet the requirements of complex and variable three-dimensional shaped ceilings. Moreover, the gypsum board ceiling involves multiple types of workers in construction, which is not conducive to overall coordination, has a long construction period, and high costs, and is not conducive to the realization of the architectural space design concept and the perfect display of the architectural space decoration effect.

[0004] The traditional construction plan for the three-dimensional inclined surface shaped ceiling uses aluminum plates processed into a single unit-shaped aluminum plate with a size of approximately 2.5 meters long × 2.5 meters wide. The large area of the aluminum plate causes certain difficulties in processing, transportation, and installation. This plan is time-consuming and laborious in installation, has poor construction adjustability, has a large processing difficulty for the unit-shaped aluminum plate with a size of approximately 2.5 meters × 2.5 meters wide, low construction efficiency, few optional processing manufacturers, and is also restricted to a certain extent during the transportation of the unit-shaped aluminum plate with a size of approximately 2.5 meters × 2.5 meters wide, and cannot guarantee the display of the design effect.

[0005] Taking the installation of the three-dimensional inclined surface shaped aluminum plate, i.e., the unit-shaped aluminum plate, at a height of approximately 12 meters above the building elevation and approximately 10 meters above the ceiling elevation as an example, on the one hand, the traditional design has the problem of insufficient fixed points and is prone to ceiling hoisting safety accidents; on the other hand, due to the large area of the unit-shaped aluminum plate, six to eight construction workers are required to cooperate in the installation of one unit-shaped aluminum plate, resulting in low construction efficiency; on the third hand, the unit-shaped aluminum plate usually has two vertices at different elevation positions, for example, vertex A and vertex B are not at the same elevation position. In this case, when installing, it is necessary to ensure the accurate installation elevation of a single unit-shaped aluminum plate, and also ensure that the vertices A of four adjacent unit-shaped aluminum plates and the installation elevations of vertex A are the same, and the vertices B of four adjacent unit-shaped aluminum plates and the installation elevations of vertex B are the same. And a large-scale ceiling decoration project usually requires at least three-digit unit-shaped aluminum plates. Therefore, the processing difficulty of the three-dimensional inclined surface shape is large, and the installation difficulty is even greater. If the inclined surface direction of the three-dimensional inclined surface shape is incorrect during the installation process, it cannot be adjusted on site. Summary of the Invention

[0057] This application researches and designs the construction technology of a three-dimensional inclined plane shaped ceiling suspension, which is applied to the ceiling decoration project of large spaces with a floor height of more than ten meters. This application discloses a construction method for a three-dimensional inclined plane shaped ceiling suspension, which includes some steps or all steps of the following embodiments; that is, the construction method for a three-dimensional inclined plane shaped ceiling suspension includes some technical features or all technical features of the following.

[0058] In one embodiment of this application, a construction method for a three-dimensional inclined plane shaped ceiling suspension is as Figure 1 shown, and it includes the steps: S300, measuring and setting out; S400, concealed works construction; S500, production of a steel skeleton conversion layer; S600, installation of three-dimensional inclined plane shaped aluminum plates; S700, installation of lighting fixtures. The above-mentioned construction method for a three-dimensional inclined plane shaped ceiling suspension is applicable to large ceiling decoration projects in ultra-high floor height spaces, has the advantages of accuracy and reliability, is conducive to providing a fast and safe construction plan, meets the technical requirements of complex and variable, three-dimensional shaped ceilings and multi-disciplinary and multi-person construction, is conducive to overall coordination to improve construction efficiency, thereby reducing the construction period and capital cost.

[0059] In one of the embodiments, before step S300, the construction method for a three-dimensional inclined plane shaped ceiling suspension further includes the step: S200, erection of a scaffold; and, after step S700, the construction method for a three-dimensional inclined plane shaped ceiling suspension further includes the step: S800, removal of the scaffold. A construction method for a three-dimensional inclined plane shaped ceiling suspension is as Figure 2 shown, and it includes the steps: S200, erection of a scaffold; S300, measuring and setting out; S400, concealed works construction; S500, production of a steel skeleton conversion layer; S600, installation of three-dimensional inclined plane shaped aluminum plates; S700, installation of lighting fixtures; S800, removal of the scaffold. When erecting the scaffold, the spacing between the vertical poles is 1500×1500mm, the step distance of the horizontal poles is 1800mm. When the vertical poles reach the bottom plate, a 200×50×3000 long wooden board is provided at the lower end of the vertical poles; when the vertical poles are on the floor slab, in addition to providing a long wooden board, a scaffold with the same vertical pole spacing is set at the position directly below the vertical poles on the next lower floor of the floor slab for unloading. A total of two layers of unloading are provided, and the number of vertical poles in the lowest layer is halved. The stability of the full hall scaffold should be protected by diagonal bars, that is, scissors braces. The scaffold connecting members, scissors braces, etc. must be carried out synchronously. Pay attention to safety when removing the scaffold. Execute according to the predetermined removal sequence. When removing, the stability and firmness of the scaffold should be ensured, and necessary connecting members and diagonal braces should be added. In this way, the three-dimensional inclined plane shaped design scheme is realized. It can be understood that the construction methods for a three-dimensional inclined plane shaped ceiling suspension in each embodiment have relatively high requirements for the safety of the overall construction, and it is necessary to ensure the firmness of the ceiling construction, prevent safety accidents caused by too high construction ceilings, and the ceiling work of the ceiling must also be completed according to the time nodes to vacate the construction time for the walls and shaped walls.

[0060] In one embodiment, before step S200, the construction method for the three-dimensional inclined surface shaped ceiling suspension also includes the step: S100, preparation before construction. In one embodiment, after step S800, the construction method for the three-dimensional inclined surface shaped ceiling suspension also includes the step: S900, ground construction. In one embodiment, before step S200, the construction method for the three-dimensional inclined surface shaped ceiling suspension also includes the step: S100, preparation before construction; and after step S800, the construction method for the three-dimensional inclined surface shaped ceiling suspension also includes the step: S900, ground construction. A construction method for a three-dimensional inclined surface shaped ceiling suspension is as Figure 3 shown, which includes the steps: S100, preparation before construction; S200, scaffolding erection; S300, measurement and layout; S400, concealed works construction; S500, production of steel skeleton conversion layer; S600, installation of three-dimensional inclined surface shaped aluminum plates; S700, installation of lighting fixtures; S800, scaffolding removal; S900, ground construction.

[0061] Specifically, the preparation before construction is also the preparation in the early stage of construction. When entering the construction site, the materials and facilities that affect the construction are cleaned up, and the construction area is reasonably arranged, including the processing site, raw material yard, and temporary yard for finished components. The materials entering the site are stacked neatly and marked. The temporary power supply facilities are installed in place and are safe and reliable, and the fire protection facilities comply with the fire safety management regulations. For example, for the construction in Shenzhen, the requirements of the "Regulations on Fire Safety Management of Construction Sites in Shenzhen" are followed, and sufficient on-site fire fighting equipment and fire protection facilities are configured. It is also necessary to prepare construction machinery such as electric welders, bench drills, cutting machines, electric hand drills, portable electric saws, and steel straightedges. In addition, materials such as three-dimensional inclined surface shaped aluminum plates, chemical bolts, expansion bolts, angle steels, and hanging rods need to be prepared. Further, the wall thickness of the three-dimensional inclined surface shaped aluminum plate should be greater than or equal to 3 millimeters. The ground construction mainly considers the later installation of instruments and their circuits, as well as some cleaning work.

[0062] In one of the embodiments, step S300 includes: S310, using the ground grid layout method for precise positioning; S320, projecting the ground layout onto the ceiling of a tall space over ten meters. This is one of the important inventive points of this application and can be regarded as a core key technology. The space is divided into a grid layout to ensure high layout accuracy, which is conducive to accurately projecting onto the high-altitude ceiling. It can be understood that since this application involves construction methods, it is necessary to execute in accordance with design and construction technical requirements, attach importance to measurement work, and on this premise, do a good job in all measurement and layout work. After entering the site, first conduct a review of the construction drawings on the drawings to ensure the correctness of the design drawings. Secondly, conduct handover acceptance of the coordinate points and level points on the site. When the error is found to be too large, the design should be adjusted. Only after confirmation can the formal positioning be carried out. Further, in step S310, it is carried out in three steps: measurement, verification, and determination of drawing. First, measure the elevation of each floor, the position of the axis, the size of the door opening, and the flatness of the ground and walls to ensure that all drawing items are horizontal and vertical.

[0063] In one embodiment of specific application, precise measurement and layout are carried out on the inclined surface modeling ceiling of a 12-meter-high space through the grid ground layout projection method. Before the secondary construction of mechanical and electrical, heating, ventilation, fire protection, and intelligent engineering is carried out, ground grid layout is carried out to confirm the ceiling modeling positioning layout. The inclined surface modeling ceiling is positioned by infrared projection into the tall space, and at the same time, the node control matching with the installation of each specialty is checked. After the secondary construction of mechanical and electrical, heating, ventilation, fire protection, and intelligent engineering, the ceiling modeling positioning and the position of ceiling equipment pipelines are rechecked to ensure the accuracy of measurement and layout, improve the speed and accuracy of engineering measurement, reduce construction errors, and provide a solid foundation for later construction.

[0064] In one of the embodiments, in step S400, according to the integrity of the ceiling plane, reserved positions for lighting fixtures, fire smoke alarms, and automatic sprinkler heads are set, so that the lamp panels and lamp slots of the lighting fixtures are connected to the ceiling plane, and the fire smoke alarms and automatic sprinkler heads are installed on the ceiling plane. The concealed works of the ceiling involve many safety factors. Step S400 is executed after step S300, but it should be planned in advance. For example, tasks such as the cooperation of the end of the fire sprinkler, the treatment of the rolling shutter closing, the air duct elevation, and the cooperation of the intelligent end can be planned at step S100, and a cooperation task book and a cooperation work plan are made. Further, in step S400, the design of the reserved positions is also used to avoid situations such as cross-operation chaos, inconsistent end closures, inconsistent hole openings, and non-cooperation in construction between the decoration project and the installation operations of mechanical and electrical, heating, ventilation, fire protection, elevator, intelligent engineering, etc., so as not to seriously affect the quality of the overall project. The concealed works should handle the relationship between the ceiling equipment and the three-dimensional inclined surface modeling ceiling. There are downlights, fire smoke alarms, sprinkler heads, etc. installed on the surface of the three-dimensional inclined surface modeling ceiling. If the relationship between these devices and the top surface is not handled well, it will damage the integrity of the ceiling and affect the appearance.

[0065] In an embodiment of a specific application, when installing the lamp panel and the lamp slot, the integrity of the suspended ceiling plane should be considered. The lamp panel and the lamp slot should not be installed unevenly, and they should not fit poorly with the top surface. When installing the automatic sprinkler head and the smoke detector, they must be installed on the suspended ceiling plane. The automatic sprinkler head must be connected to the water pipe of the automatic sprinkler system through the suspended ceiling plane. The water pipe should not be reserved too short, otherwise the automatic sprinkler head cannot be connected to the water pipe on the suspended ceiling surface, and there should be no obstacles around the sprinkler head.

[0066] In one of the embodiments, in step S500, the ㄇ-shaped steel skeleton conversion layer is connected to the building structure or the load-bearing member to make the installation points of the steel skeleton conversion layer uniform. The following provides an embodiment of a specific implementation. First, use the ground grid layout method for precise positioning. Project the precise ground layout to the ceiling of a tall space more than about ten meters. Connect the ㄇ-shaped steel skeleton conversion layer to the building structure or the load-bearing member to solve the safety problems of uneven installation points of the steel skeleton conversion layer affected by the ceiling equipment pipes and insufficient force of the steel skeleton conversion layer. Design the plan before construction, and adjust the dimensions and slope degree on-site with the in-depth personnel, the aluminum plate customization manufacturer, and the construction person in charge to ensure the accuracy of the construction drawing and the customization effect of the three-dimensional inclined aluminum plate. Apply the method of starting from the four middle unit-shaped aluminum plates and installing them synchronously in both the vertical and horizontal directions, and gradually installing them as a whole towards the surrounding areas. When installing, synchronously adjust the installation height of the three-dimensional inclined-shaped aluminum plates in both the vertical and horizontal directions to ensure that the elevation of the adjacent vertices of the four adjacent unit-shaped aluminum plates is the same.

[0067] Continuing with the actual construction as an example, the application building has a floor height of about 12 meters. Other embodiments in actual construction can also be higher, such as 20 meters. The designed floor height of the ceiling is about 10 meters, and the length of the suspender is greater than 1.5 meters. It is necessary to arrange a steel skeleton conversion layer. According to the calculation of the building structure and the ceiling load, the rooting and fixing points of the application building steel skeleton conversion layer are changed from the original building floor to the original building structural beam. For the traditional steel skeleton conversion layer, the horizontal angle steel is used to install the suspender. When the length of the suspender is greater than 1.5 meters, it is easy to cause the imbalance of the steel skeleton conversion layer system, resulting in an uneven surface after the ceiling installation and not meeting the safety requirements of the walkable steel skeleton conversion layer. Further, in this application, the galvanized angle iron is made into a ㄇ-shaped connector, and the welding points are fully welded. The horizontal angle steel is fixed to the top of the original building structural beam with expansion bolts, and at least two installation points are arranged on the horizontal angle steel of one ㄇ-shaped connector. After the ㄇ-shaped connectors are reasonably arranged in terms of spacing and stress positions and fixed, one or two longitudinal angle steels are welded to the lower end of each ㄇ-shaped connector, that is, the 50×50×5 galvanized angle steel conversion layer at the bottom in the long side direction. When welding the 50×50×5 galvanized angle steel conversion layer at the bottom, it should first meet the design elevation of the ceiling and reserve the installation space for the three-dimensional inclined surface shaped aluminum plate. The 50×50×5 galvanized angle steel conversion layers at the bottom are all fixed at both ends of the longitudinal angle steel to the load-bearing column. Finally, a horizontal angle steel needs to be arranged above the bottom conversion layer to connect multiple longitudinal bottom conversion layers, forming a whole grid with uniform stress. At this time, the 50×50×5 galvanized angle steel conversion layer supports as a whole system in the same space, effectively combines with the equipment in the ceiling to avoid conflicts, improves the hoisting safety of the steel skeleton conversion layer, and provides a good basic structure for the installation of the three-dimensional inclined surface shaped ceiling.

[0068] Further, in one embodiment, before step S600, it includes: S610, installing a grid-shaped flat aluminum plate. Further, in one embodiment, before step S600, it includes: S610, installing a grid-shaped flat aluminum plate as the installation foundation for the unit-shaped aluminum plate, and the unit-shaped aluminum plate can be fixed under the grid-shaped flat aluminum plate. That is, the grid-shaped flat aluminum plate is installed first before installing the three-dimensional inclined surface-shaped aluminum plate as the installation foundation for the unit-shaped aluminum plate. For example, according to the previously determined installation sequence and the layout diagram of the unit-shaped aluminum plate, the grid-shaped flat aluminum plate is installed first as the installation foundation for the unit-shaped aluminum plate. The grid-shaped flat aluminum plate is divided into 600 mm wide and 300 mm wide. Different specifications of grid-shaped flat aluminum plates can be selected according to the position of the load-bearing column, and on this basis, the installation of the three-dimensional inclined surface-shaped aluminum plate is realized. Continuing with the actual construction as an example, there are twelve load-bearing columns in the exhibition hall. The three-dimensional inclined surface-shaped ceiling is divided into grid-shaped flat aluminum plate beams 600 mm wide according to the twelve load-bearing columns. The grid-shaped flat aluminum plate is further subdivided into multiple 300 mm wide flat aluminum plate beams. The three-dimensional inclined surface-shaped aluminum plate is installed in the middle of the 300 mm wide flat aluminum plate beams. The design requires a 100 mm gap between the unit-shaped aluminum plate and the 300 mm wide flat aluminum plate beam around the unit-shaped aluminum plate. After installing the grid-shaped flat aluminum plate, when installing the unit-shaped aluminum plate, at least two construction workers carry out the installation simultaneously. One person climbs to the steel frame conversion layer and fixes it on the steel frame conversion layer with aluminum plate installation bolts, and at the same time cooperates with the construction workers below the unit-shaped aluminum plate to adjust and fix it. It can be seen that the construction of this application is convenient.

[0069] In one embodiment, as Figure 4 and Figure 5 shown, the unit-shaped aluminum plate 110 of the three-dimensional inclined surface-shaped ceiling 100 is fixed to the ceiling 200 through the fixing member 120. Since the three-dimensional inclined surface-shaped ceiling is a three-dimensional inclined surface-shaped aluminum plate about 2.5 meters long × 2.5 meters wide as the unit-shaped aluminum plate, transportation and installation are both inconvenient. In one embodiment, in step S600, each unit-shaped aluminum plate of the three-dimensional inclined surface-shaped aluminum plate is decomposed into a middle part and symmetric two side parts. When installing, the middle part is installed first and adjusted to the design elevation, and then the two side parts are installed. In one embodiment, the elevation positions of the middle part and the two side parts are set differently. Further, in one embodiment, the middle part has a rectangular structure or has a rectangular structure, and the middle part is a symmetric shape. The monomer of the three-dimensional inclined surface-shaped aluminum plate, that is, each three-dimensional inclined surface-shaped aluminum plate is called a unit-shaped aluminum plate, as Figure 6As shown, the vertex A and the vertex B of the unit-shaped aluminum plate are not at the same elevation. During installation, it is necessary to ensure that the installation elevation of the single unit-shaped aluminum plate is accurate, and it is also necessary to ensure that the installation elevations of the vertices A and vertex A of the four adjacent unit-shaped aluminum plates are consistent, and the installation elevations of the vertices B and vertex B of the four adjacent unit-shaped aluminum plates are consistent. After testing, the entire rectangular unit-shaped aluminum plate 110, for example, about 2.5 meters long and 2.5 meters wide, is decomposed into three aluminum plates: a first side portion 111, a middle portion 113, and a second side portion 112 for processing and installation. The installation order of a single unit-shaped aluminum plate is to install the middle portion 113 first, and when the middle portion 113 is adjusted to the design elevation, install the first side portion 111 and the second side portion 112. The processing volume of aluminum plates is large, and the decomposition of three-dimensional beveled aluminum plates improves the cutting speed and accuracy, reduces material processing loss, and ensures the processing quality of three-dimensional beveled aluminum plates; improves the processing speed of three-dimensional beveled aluminum plates, and greatly shortens the supply cycle of three-dimensional beveled aluminum plates; and the decomposition of three-dimensional beveled aluminum plates is convenient for transportation, reducing transportation costs and further reducing the project cost.

[0070] In one embodiment, step S600 includes: S620, synchronously installing from the middle four unit shaped aluminum plates in the vertical and horizontal directions; S630, gradually installing to the surroundings. In one embodiment, in step S630, the three-dimensional inclined shaped aluminum plates in the vertical and horizontal directions are synchronously adjusted in installation height during installation to ensure that the adjacent vertices of the four adjacent unit shaped aluminum plates are consistent in elevation. In one embodiment, step S600 includes: S620, synchronously installing from the middle four unit shaped aluminum plates in the vertical and horizontal directions; S630, gradually installing to the surroundings, and the three-dimensional inclined shaped aluminum plates in the vertical and horizontal directions are synchronously adjusted in installation height during installation to ensure that the adjacent vertices of the four adjacent unit shaped aluminum plates are consistent in elevation. The remaining embodiments are similar and will not be elaborated on. Figure 6 and Figure 7 As shown, the first side portion 111 and the middle portion 113 are fixed by a locking member 114, and the second side portion 112 is also fixed by the locking member 114 to the middle portion 113. The first side portion 111 or the second side portion 112 is also fixed to the first side portion 111 or the second side portion 112 of the other unit-shaped aluminum plate by the locking member 114. Figure 8 The unit-shaped aluminum plate 110 of the three-dimensional inclined surface ceiling 100 is fixed on the ceiling 200 through a fixing member 120 .

[0071] Continuing with the actual construction as an example, in the present application, the space is divided into a grid for layout, ensuring high layout accuracy; the installation of the three-dimensional inclined surface shaped aluminum plate is fixed to the aluminum plate through bolts; when installing the three-dimensional inclined surface shaped ceiling, the installation is carried out simultaneously in both the vertical and horizontal directions from the four unit-shaped aluminum plates in the middle, and gradually installed towards the periphery, ensuring that the installation heights of the elevation levels of the four adjacent units of the three-dimensional inclined surface ceiling are the same, thus forming a reliable construction method for the three-dimensional inclined surface shaped ceiling suspended ceiling. The construction method for the three-dimensional inclined surface shaped ceiling suspended ceiling has been actually applied on-site in multiple construction projects of the applicant.
