Description

Technical Field

[0001] The invention relates to the technical field of large space assembled light box construction, and in particular to an ultra-long arc light box based on an elliptical ceiling and an installation method thereof. Background Art

[0002] At present, large venues with hyperbolic GRG shapes are emerging in various parts of China, with high space, large span and multi-function as their prominent features. Among them, the scientific research hub project of Chengdu Industrial Research Institute Branch of China Mobile Communications Group Co., Ltd. includes an elliptical lecture hall with a tall and large space decorative ceiling. The elliptical lecture hall not only requires the ceiling effect of a two-story corridor, but also has a three-circle protruding ceiling light box shape to echo the hyperbolic GRG shape of the wall. The light box is 0.2 meters wide, protruding from the ceiling up to 0.5 meters, with a length of more than 60 meters and a radius ranging from 30 meters to 80 meters.

[0003] like Figure 5 and Figure 6 As shown, the traditional super-long arc light box based on the elliptical ceiling includes a ceiling system and a light box system installed under the conversion layer, wherein the conversion layer includes an angle steel a, a first transverse keel b and a second transverse keel c arranged on the angle steel a, the ceiling system includes a first suspension rod d, a main keel e, a secondary keel f and a first base plate g connected in sequence from top to bottom, the light box system includes a second suspension rod h, a keel frame i, a second base plate j, an LED lamp k and a lamp film l, the first suspension rod d is suspended at the bottom of the first transverse keel b, the second suspension rod h is suspended at the bottom of the second transverse keel c, the keel frame i is connected to the bottom of the second suspension rod h and extends out of the first base plate g, the second base plate j is fixed on the outer peripheral surface of the keel frame i and extends downward to form a lamp trough m with an opening arranged downward, the LED lamp k is installed in the lamp trough m, and the lamp film l is encapsulated at the bottom of the lamp trough m; the traditional construction steps of the above structure are as follows:

[0004] 1. According to the position of the light box system, the first transverse keel b and the second transverse keel c are arranged on the angle steel a to form a conversion layer, and the second suspension rod h is fixed to the second transverse keel c by threaded fasteners;

[0005] 2. Fix the first suspension rod d to the first transverse keel b through threaded fasteners, fix the main keel e under the first suspension rod d through suspension fittings, fix the secondary keel f under the main keel e through adapters, and arrange the main keel e parallel to the angle steel a, and the secondary keel f parallel to the first transverse keel b; set the main keel e under the second suspension rod h to be disconnected, and reserve an arc-shaped opening n for the keel frame i of the light box system and the second base plate j;

[0006] 3. Fix the keel frame i under the second suspension rod h, cover the second base plate j on the outer peripheral surface of the keel frame i, and extend the second base plate j located at the two vertical surfaces of the keel frame i out of the lower end of the keel frame i to form a lamp trough m with the opening facing downward;

[0007] 4. Treat the surface of the second base plate j in the lamp trough m with a white reflective finish and introduce electrical wires;

[0008] 5. Cover the second base plate j below the secondary keel f with an aluminum plate finish o on the outer facade;

[0009] 6. Install the first base plate g under the secondary keel f through the hanging parts, and ensure that the bottom surface of the first base plate g is lower than the top surface of the aluminum plate facing o. Perform the closing treatment on the junction between the first base plate g and the aluminum plate facing o, and then perform the facing treatment on the surface of the first base plate g;

[0010] 7. Install the LED lamp k in the lamp trough m and connect it with the wires, and install the lamp film l at the bottom of the lamp trough m.

[0011] The use of the above traditional construction structures and methods will have the following disadvantages:

[0012] First, because the finished light boxes on the market are independent and have limited specifications, the above-mentioned special light box system will be directly assembled on site using a keel frame made of angle steel and a second base plate made of flame retardant board or fireproof board. Not only are there problems such as large on-site processing errors and unguaranteed curvature; and the load of the traditional on-site light box includes the sum of the second hanger h, keel frame i, second base plate j, and metal finishing layer of the light box, with a load of about 58KG per meter and a load of 290KG per square. The specification requires that lamps weighing more than 3KG should be hung on the load-bearing structure, so a conversion layer needs to be set up. According to the conventional single-layer angle steel conversion layer design, the maximum stable bearing capacity is about 42KG, which is completely unable to meet its load requirements. Therefore, the first horizontal keel b for connecting the ceiling system and the second horizontal keel c for connecting the light box system must be added to the angle steel a of the existing conversion layer to form a larger steel structure conversion layer to ensure force safety, resulting in higher manufacturing costs;

[0013] In addition, the only board on the market that has the bending performance to meet the arc shape of the light box and has a normal cost is the wooden flame retardant board, but its fire protection grade can only reach B1 grade. As the base material for ceiling materials and lamp installation, the regulations require it to reach Class A fire protection. The other non-wooden flame retardant boards that can reach Class A, such as glass magnesium boards and cement fiber boards, have poor bending performance and poor nail holding force, and cannot meet the needs of the base modeling. In addition, the lightweight high-strength calcium silicate board that can meet the above requirements has a high base cost. The lightweight high-strength calcium silicate board with a thickness of 3-5mm can meet the bending curvature, but because the material has large elastic deformation, it needs to be shaped with a keel, which greatly increases the overall material and production costs.

[0014] 2. The keel frame i and the second base plate j of the light box system penetrate the keel and base plate of the ceiling system, so that the first base plate g connected to the side of the light box system needs to be processed into an arc section according to the corresponding size before it can be hoisted, which increases the manufacturing cost; the keel frame i and the second base plate j of the light box system are installed and manufactured on-site. Affected by the manual operation errors of the workers, the arc section of the first base plate g must also be manufactured on-site to ensure the matching accuracy. Therefore, the light box system and the ceiling system need to be installed in an interlaced construction method. The construction process is complicated and cumbersome, resulting in a long construction period.

[0015] 3. To ensure the force requirements, the main keel e and the secondary keel f located between the three light box systems need to be disconnected when encountering a light box. The two-area ceiling keels between the light boxes can only adopt a multi-section structure to be connected into a broken arc that matches the shape of the light box. The construction process is cumbersome, resulting in a long construction period. Summary of the invention

[0016] The purpose of the present invention is to address the deficiencies of the prior art and provide an ultra-long arc light box based on an elliptical ceiling and an installation method thereof which has low cost, simple construction process and good safety.

[0017] The ultra-long arc-shaped light box based on an oval ceiling provided by the present invention includes a ceiling system and a light box system installed under the conversion layer. The ceiling system includes a first hanging rod, a main keel, a secondary keel, and a first base plate connected in sequence from top to bottom. The conversion layer includes a number of parallel angle steels, which are arranged non-coplanar with both the main keel and the secondary keel. The light box system includes an upper hanging rod, a C-shaped connecting piece, a lower hanging rod, a number of arc-shaped outer shells, a number of inner bases, a number of LED lights, and a number of light films. Both the first hanging rod and the upper hanging rod are connected to the angle steel. The upper end of the lower hanging rod is connected to the upper hanging rod through the C-shaped connecting piece, and the lower end passes through the first base plate and is connected to the arc-shaped outer shell. The arc-shaped outer shell is arranged closely against the bottom surface of the first base plate, and adjacent arc-shaped outer shells are sequentially connected at the bottom of the first base plate to form an arc-shaped light box. Elastic arms that are arranged to bend inward are provided on both sides of the bottom of the arc-shaped outer shell, and elastic arms that are in clearance fit and clamped with the slots are provided on both sides of the bottom of the inner base. The inner base is axially position-adjustably clamped inside the arc-shaped outer shell through the elastic arms. The LED lights are installed on the inner base, and the light film is clamped between the two slots at the bottom of the arc-shaped outer shell.

[0018] To facilitate the positioning and adjustment of the arc-shaped outer shell, the C-shaped connecting piece includes a upper horizontal arm, a vertical connecting arm, and a lower horizontal arm connected in sequence. A first strip-shaped hole arranged along the axial direction of the angle steel is opened on the upper horizontal arm, and a second strip-shaped hole arranged perpendicular to the axial direction of the angle steel is opened on the lower horizontal arm. The C-shaped connecting piece is connected to the bottom of the upper hanging rod through a threaded fastener installed in the first strip-shaped hole and is adjustable in the front-back position. The lower hanging rod is connected to the bottom of the C-shaped connecting piece through a threaded fastener installed in the second strip-shaped hole and is adjustable in the left-right position. The lower hanging rod is installed at the bottom of the upper hanging rod through the C-shaped connecting piece and is adjustable in both the front-back and left-right positions.

[0019] To facilitate quick installation and ensure that the light film is overall straightened, flat, and seamless, the light box system further includes a clamping member for clamping the light film. The upper end of the clamping member is detachably connected to the elastic arm, and the lower end is closely arranged against the slot. The light film is clamped between the two slots at the bottom of the arc-shaped outer shell through the clamping member.

[0020] To ensure the fire safety of the ceiling, the arc-shaped outer shell, the inner base, and the light film are all made of A-level fireproof materials.

[0021] The installation method of the present invention applicable to the above-mentioned ultra-long arc-shaped light box based on an oval ceiling includes the following steps:

[0022] S1. Construct the angle steel, synchronously embed the upper hanging rod and the C-shaped connecting piece, and reserve the lamp wires.

[0023] S2. Complete the installation of the first hanging rod, the main keel, the secondary keel, and the first base plate of the ceiling system according to the normal construction process. Both the main keel and the secondary keel are arranged non-coplanar with the angle steel.

[0024] S3. The arc-shaped housing, inner base, and lamp film in the factory prefabricated light box system;

[0025] S4. Pre-layout the arc-shaped housing on the ground;

[0026] S5. Pre-assemble the arc-shaped housing on the first base plate of the suspended ceiling system;

[0027] S6. Through the access hatch for maintenance personnel, drill installation holes on the first base plate and the arc-shaped housing directly below the upper suspension rod. Pass the lower suspension rod through the installation holes. Fasten the upper end of the lower suspension rod to the C-shaped connecting piece with threaded fasteners, and fasten the lower end of the lower suspension rod to the arc-shaped housing with threaded fasteners;

[0028] S7. Install the LED lights in the inner base, synchronously and segmentally snap-fit the inner base with the installed LED lights into the arc-shaped housing. After leveling, fasten them to ensure the overall straightness, and connect the lamp wires;

[0029] S8. Snap-fit the lamp film at the bottom of the arc-shaped housing.

[0030] The specific steps of factory prefabrication in step S3 are as follows:

[0031] S31. 3D scanning

[0032] Use a 3D scanner to perform a 360-degree scan of the main structure and pipelines, obtain the on-site actual structural pipeline point cloud model, and convert it into a mechanism and mechanical and electrical pipeline model;

[0033] S32. BIM reverse modeling

[0034] On-site technical and detailed design personnel first construct the suspended ceiling shape and deepen the nodes according to the obtained deformation data, then reverse-build to form a BIM model, and finally perform the final optimization and establishment of the light box system structure model;

[0035] S34. Drawing design

[0036] Use Rhinoceros software with the Grasshoper plug-in to perform the drawing design of the arc-shaped housing, inner base, and lamp film. Adjust the drawing size with GH parameters. Through the comprehensive ceiling layout, avoid the conflict between the positions of various mechanical and electrical air vents, lamps, sprinkler end points, and the light box installation on the first base plate of the overall layout, make the arc transition smooth at the joints of each section of the arc-shaped housing, and make the three arc-shaped light boxes parallel to each other and evenly arranged to obtain the design drawings;

[0037] S35. Extract the drawing dimensions and place an order for the factory production of the arc-shaped housing, inner base, and lamp film.

[0038] The specific steps of pre-assembly in step S4 are as follows:

[0039] S41. Robot wire laying and positioning layout

[0040] Extract the coordinates of the arc shell control corner points in the BIM model and project them onto the ground to form a unique layout of the layout points. Import the layout of the layout points into the layout robot. Use the layout robot to project the laser of the layout points onto the working surface on site. The model point layout marking personnel mark and number the layout points according to the design drawings and positions. All the layout points are uniquely numbered. After the layout is completed, random points are checked.

[0041] S42. Construction preparation

[0042] Carry out the handover of the working surface, technical preparation of drawings, transportation and stacking of materials, and the implementation of construction measures;

[0043] S43, curved shell pre-layout

[0044] The curved shell should be pre-arranged and marked on the ground according to the layout diagram and the marking numbers on the ground. Slight adjustments should be made to the arc for a smooth transition at the intersection of each section. Every two sections should be connected to ensure that the top connection base is flat and smooth.

[0045] The specific steps of pre-assembling the arc-shaped housing in step S5 are as follows:

[0046] S51, marking and positioning installation control points on the upper surface of the arc-shaped housing, and projecting the points vertically onto the first base plate of the ceiling system;

[0047] S52. Lift the arc-shaped shell by the vertical lifting scissor lift platform, adjust the position, and fix the arc-shaped shell to the first base plate by auxiliary connecting screws. Consider the conflict with the vertical smoke barrier wall and disconnect it and set the head.

[0048] The specific steps for positioning the mounting holes in step S6 are as follows:

[0049] S61. Through the access opening, reinforce the upper suspension rod from top to bottom according to the position of the angle steel;

[0050] S62. Drill a layout observation hole on the first base plate, and guide the laser of the plumb line from the ground to the upper part of the conversion layer through the layout observation hole. Use the plumb line to extend the position of the upper suspension rod from the upper part of the conversion layer through the ground to the arc-shaped shell, and accurately locate the installation hole.

[0051] In the step S8, it also includes a clamp for installing the lamp film. The clamp is fixed on the elastic arm of the inner base according to the spacing on the drawing, and the lamp film is clamped between the clamps to complete the installation of the entire light box system.

[0052] Compared with the prior art, the present invention has the following advantages:

[0053] 1. The arc-shaped light box is formed by sequentially connecting several arc-shaped outer shells. The arc-shaped outer shells can be batch customized in sections by the factory with prefabricated openings, achieving efficient, precise, stable, and batch implementation. This not only solves the problem of processing errors in on-site light box production, ensures the overall flatness and straightness of the ultra-long arc-shaped metal light box and the overall effect, but also reduces material losses and optimizes the construction process, thereby shortening the construction period and creating economic value. Moreover, it has a small self-weight, and a conversion layer usually formed by several unidirectional angle steels can meet its load requirements, reducing the manufacturing cost.

[0054] 2. The arc-shaped outer shells are sequentially connected to the angle steel through lower suspension rods, C-shaped connectors, and upper suspension rods, simplifying the more complex keel, base layer, and panel system of the overall box body component; the lower suspension rods penetrate through the first base plate, and only installation holes for the lower suspension rods to penetrate need to be drilled on the first base plate, eliminating the need to process an arc-shaped section on-site, reducing the manufacturing cost. Moreover, the arc-shaped outer shell and the inner base can be assembled after the entire ceiling system is installed, reducing the problem of process interpenetration between the ceiling system and the light box system, simplifying the construction process, and shortening the construction period.

[0055] 3. The arc-shaped outer shell is arranged closely against the bottom surface of the first base plate, and the secondary keel of the ceiling system does not need to be disconnected, making the construction process simple and reducing the construction period.

[0056] 4. With a matching light film and standardized dimensions of the inner base, the overall shape of the light film is ensured, and the straight effect of the light film is ensured.

[0057] 5. The elastic arms of the inner base are clamped with the card slots of the arc-shaped outer shell through clearance fit, which is not only convenient for the axial position sliding fine adjustment of the inner base within the arc-shaped outer shell, but also enables the inner base to be stably leveled within the arc-shaped outer shell by its own gravity.

[0058] 6. For assembled installation, workers can operate after simple training, which is convenient for large-area implementation on-site, shortens the construction period, ensures the overall effect of the nearly 80-meter-long arc-shaped light box, reduces material losses and optimizes the construction process, thereby shortening the construction period and creating economic value. At the same time, it can also be disassembled twice, facilitating inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
