Technical Field

[0001] The present invention relates to the technical field of building decoration construction, and particularly to a ceiling structure with a luminous soft film and a construction method thereof. Background Art

[0002] The ceiling is an important part of the top decoration of an indoor space, and its structure is mainly composed of suspenders, keels and decorative panels. As a key component connecting the building main structure and the ceiling, the suspenders are mostly made of steel bars or screws and are fixed on the floor slab through expansion bolts, mainly playing the roles of hanging and bearing to ensure the overall stability of the ceiling. The keel is like the skeleton of the ceiling, divided into the main keel and the secondary keel. The main keel is installed parallel to the long direction of the room, bearing the main load of the ceiling and transmitting the force to the suspenders; the secondary keel is arranged perpendicular to the main keel and is used to fix the decorative panel. The two are intertwined to form a stable framework. According to the material, the keel can be divided into wooden keel, light steel keel, etc. Among them, the light steel keel is widely used in modern decoration due to its advantages of fire prevention, moisture resistance and not easy to deform. The decorative panel is the surface material of the ceiling, directly affecting the decorative effect and service function. Common ones include gypsum board, mineral wool board, aluminum gusset plate, etc. The gypsum board has rich shapes and is suitable for various decorative styles; the mineral wool board has outstanding sound absorption performance and is often used in meeting rooms and offices; the aluminum gusset plate is mostly used in kitchens and bathrooms due to its easy cleaning and corrosion resistance. The suspenders, keels and decorative panels cooperate with each other, not only beautifying the indoor space, but also realizing functions such as sound insulation, heat insulation and hiding pipelines.

[0011] Preferably, an installation groove is formed inside the main keel. A main air duct and an auxiliary air duct are arranged inside the main keel. A partition is arranged in the middle of the installation groove. A plurality of air outlets are formed in the bottom surface of the installation groove. Two third installation holes are formed in the top surface of the installation groove. The two third installation holes are symmetrically arranged through the partition. A second micro-turbine fan is arranged inside one of the third installation holes, and a first micro-turbine fan is arranged inside the other third installation hole. The outer wall of the bottom of the auxiliary air duct is fixedly connected to the inner wall of the air outlet. A plurality of auxiliary air ducts and one main air duct form a group. There are two groups of auxiliary air ducts and main air ducts inside the installation groove. The two groups of auxiliary air ducts and main air ducts are symmetrically arranged through the partition.

[0012] Preferably, both the main air duct and the auxiliary air duct are of a hollow structure. The internal spaces of the main air duct and the auxiliary air duct are communicated. A connection port is formed in the top surface of the main air duct. The connection port corresponds to the output end of the second micro-turbine fan and the input end of the first micro-turbine fan.

[0013] Preferably, the main keel is made of 6063-T5 aluminum alloy profile with a cross-sectional dimension of 30 mm in width and 50 mm in height. The diffusion plate is made of a 3-mm-thick PMMA optical grade sheet with a haze value ≥ 92%.

[0014] Preferably, the color temperature of the LED light strip is adjustable between 3000K and 6000K, and 60 lamp beads are arranged per meter inside the LED light strip.

[0015] A construction method for a ceiling structure with a light-emitting soft film includes the following steps: S1. Set out and position according to the design drawings, and fix the suspender with expansion bolts; S2. Level the assembled main keel, with an allowable error ≤ 3 mm / 2 m; S3.

The light-transmitting soft film is heated to 60 °C with a hot air gun and then stretched and installed. After cooling, the excess part is cut.

[0016] Working principle: The main keel is used to install the entire ceiling structure at the bottom of the roof slab through the suspender. The U-shaped secondary keel is installed at the bottom of the connection structure by using the connection structure. The second installation holes on the outer walls of the main keel and the U-shaped secondary keel are used to adjust the fixed position of the connection structure. The distance between the clamping blocks at the upper and lower ends of the adjusting device is adjusted by using the adjusting device, so as to adjust the height position of the U-shaped secondary keel, and thus it can adapt to different arc-shaped models. The diffusion plate can be fixed to the bottom surface of the U-shaped secondary keel by using the middle support device, so as to support the middle part of the diffusion plate and prevent the middle part of the diffusion plate from sagging. The L-shaped edge trim keel can support the edge of the diffusion plate. The light guide plate can transport the light emitted by the LED light strips installed on the side wall of the L-shaped edge trim keel from the side wall of the diffusion plate into the diffusion plate. Then, the diffusion plate evenly disperses the light. The edge of the light-transmitting soft film is pressed into the groove of the fixing block by using the silicone pressing strip, so as to fix the light-transmitting soft film. The first printing layer, the second printing layer, the third printing layer and the fourth printing layer on the bottom surface of the diffusion plate can change the brightness of the light output by the diffusion plate, so as to achieve the purpose of light intensity gradient change. The main air duct and the auxiliary air duct can be installed in the installation groove inside the main keel. The partition plate can divide the installation groove into two spaces. The main air duct and the auxiliary air duct are installed in both spaces. The second micro-turbine fan can suck the external low-temperature air flow into the main air duct, and then disperse it through the auxiliary air duct. The first micro-turbine fan can output air flow, so that a negative pressure is generated in the main air duct at the bottom of the first micro-turbine fan, and then the hot air flow in the ceiling is discharged through the auxiliary air duct under the first micro-turbine fan, thus forming convection.

[0017] The present invention provides a ceiling structure with a light-emitting soft film and its construction method. It has the following beneficial effects: 1. In the present invention, the light guide plate uses micro-structured dots to input the light output from the LED strip into the side wall of the diffuser plate, and the diffuser plate is used to fully and evenly diffuse the light source, so that the light emission can be completed only by arranging the LED strip on the side, reducing the use of the LED strip, thus saving electric energy and the installation cost of multiple LED strips. At the same time, the diffuser plate improves the uniformity of the light, thus solving the problem that in order to improve the uniformity of the light efficiency in the traditional soft film ceiling in the suspended ceiling, most of the high-density lighting layout schemes are adopted, resulting in an increase in the installation cost and the electricity cost, and thus a significant increase in the energy consumption and the cost.

[0018] 2. In the present invention, the diffuser plate is made of PMMA optical grade sheet material, which has good optical properties and environmental protection properties, with a haze value ≥ 92%, can effectively diffuse light, reduce light pollution, and at the same time its material itself is relatively environmentally friendly. The light-transmitting soft film is installed by heating and stretching with a hot air gun, and the excess part is cut after cooling. This installation method is relatively flexible, and the soft film material has a certain recyclability after use, reducing the generation of construction waste and reflecting the environmental protection concept of green buildings.

[0019] 3. In the present invention, the main keel is provided with a main air duct and a secondary air duct inside, and ventilation is carried out by a micro-turbine fan. This design can realize the circulation of indoor air, assist in adjusting the indoor temperature to a certain extent, reduce the use frequency of equipment such as air conditioners, and reduce energy consumption.

[0020] 4. In the present invention, the main keel is fixed to the top plate by a suspension rod, and multiple main keels are connected by angle codes. The main keel and the U-shaped secondary keel are connected by a connection structure. This standardized connection method is convenient for prefabrication and production in the factory, and then rapid assembly on site, reducing the time and workload of on-site construction. The diffuser plate is connected to the U-shaped secondary keel through a middle support device and is placed on the L-shaped edge trimming keel at the edge. The light-transmitting soft film is fixed by fixing blocks and silicone pressure strips. The installation method between each component is relatively simple and easy to operate, so as to achieve the purpose of rapid installation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0023] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0024] Please refer to the attached Figure 1 and the attached Figure 8, including the main keel 5. The top surface of the main keel 5 is fixedly connected to the bottom surface of the top plate through a suspender. Multiple main keels 5 perpendicular to each other in different directions are connected by angle codes 6. The lower part of the main keel 5 is connected with a U-shaped auxiliary keel 7 through a connecting structure 1. The bottom surface of the U-shaped auxiliary keel 7 is connected with a diffusion plate 3 through a middle support device 10. The middle part of the diffusion plate 3 is fixedly connected to the bottom surface of the U-shaped auxiliary keel 7 through the middle support device 10. The edge of the diffusion plate 3 is placed on the bottom edge of the L-shaped edge-sealing keel 4 through a fixing block 13. The L-shaped edge-sealing keel 4 is fixedly connected to the wall surface by expansion screws on its side. A light guide plate 12 is arranged between the side of the L-shaped edge-sealing keel 4 and the edge of the diffusion plate 3. There are microstructure dots inside the light guide plate 12. An LED light strip is arranged between the light guide plate 12 and the side of the L-shaped edge-sealing keel 4. One side of the fixing block 13 far from the side of the L-shaped edge-sealing keel 4 is fixedly provided with a light-transmitting soft film 11 through a silica gel pressing strip 14.

[0025] Specifically, the main keel 5 is fixedly connected to the bottom surface of the top plate through a suspender, providing support and fixation for the entire ceiling structure. The angle code 6 can be used to connect the longitudinal and transverse main keels 5 to improve the integrity of the main keel 5. The connecting structure 1 can be used to install the U-shaped auxiliary keel 7 under the main keel 5 and at the same time convey the load transmitted by the U-shaped auxiliary keel 7 to the main keel 5. The U-shaped auxiliary keel 7 can support the middle part of the diffusion plate 3, making the whole diffusion plate 3 flatter, and at the same time can transmit the load of the diffusion plate 3 to the main keel 5. The middle support device 10 can be used to install the middle part of the diffusion plate 3 at the bottom of the U-shaped auxiliary keel 7. After the diffusion plate 3 fully and evenly diffuses the light and transmits it to the light-transmitting soft film 11, the light displayed by the light-transmitting soft film 11 is more uniform. The L-shaped edge-sealing keel 4 can play a role in supporting the edge of the diffusion plate 3 to maintain the stable support of the diffusion plate 3. At the same time, the L-shaped edge-sealing keel 4 can play a role in installing the light guide plate 12 and the fixing block 13. A groove is opened on one side of the fixing block 13 close to the silica gel pressing strip 14, and the silica gel pressing strip 14 together with the light-transmitting soft film 11 can be inserted into the fixing block 13. The fixing block 13 can play a role in installing the silica gel pressing strip 14, and the silica gel pressing strip 14 can play a role in fixing the light-transmitting soft film 11. The microstructure dots in the light guide plate 12 can play a role in absorbing the light emitted by the LED light strip and then conveying the light into the diffusion plate 3 from the side wall of the diffusion plate 3, so as to make the most of the light emitted by the LED light strip. Finally, only using the LED light strip on the side wall can achieve the lighting purpose. At the same time, the diffusion plate 3 can make the light source evenly emit, thus solving the problem that in order to improve the uniformity of light efficiency in the traditional soft film ceiling of the ceiling, most of them adopt the scheme of high-density lighting layout, which increases the installation cost and electricity cost, so the energy consumption and cost will increase significantly.

The telescopic hole communicates with the chute 136. The diameter of the limiting device is larger than the diameter of the telescopic hole. The return spring 135 is located inside the chute 136.

[0029] Specifically, the distance between the clamping blocks 120 can be increased by the extension rod 131 and the extension cylinder 132; the fixing knob 133 can be engaged with the fixing hole 134 to fix the extension rod 131 inside the extension cylinder 132; multiple groups of fixing holes 134 are provided on the outer wall of the extension cylinder 132, so that the extension rod 131 has multiple positions where it can be engaged, thus achieving the purpose of multi-length adjustment; the outer diameter of the fixing knob 133 corresponds to the diameter of the fixing hole 134, thereby reducing the clearance between the fixing knob 133 and the fixing hole 134 and improving the integrity; the fixing knob 133 can slide inside through the sliding groove 136; the reset spring 135 can push the fixing knobs 133 on both sides outward to the outside of the sliding groove 136 when the pressure is cancelled, so as to clamp the fixing knob 133 on the inner wall of the fixing hole 134; the diameter of the limiting device is larger than the diameter of the telescopic hole, and the limiting device can be clamped on the inner wall of the sliding groove 136 to prevent the fixing knob 133 from being completely pushed out of the sliding groove 136 when the fixing knob 133 is pushed outward by the reset spring 135; the fixing knob 133 can protrude from the inside of the sliding groove 136 through the telescopic hole; the diameter of the telescopic hole is the same as the outer diameter of the fixing knob 133, thereby reducing the clearance between the fixing knob 133 and the telescopic hole and further improving the integrity.

[0030] Please refer to the attached Figure 3 and the attached Figure 7 As shown in the figure, the middle support device 10 includes a first magnetic buckle 102 and a second magnetic buckle 103. The first magnetic buckle 102 is fixedly connected to the bottom surface of the U-shaped secondary keel 7 through a connecting rod 101, and one side of the second magnetic buckle 103 away from the first magnetic buckle 102 is fixedly connected to the top surface of the diffusion plate 3. The mutually corresponding surfaces of the first magnetic buckle 102 and the second magnetic buckle 103 attract each other.

[0031] Specifically, the first magnetic buckle 102 and the second magnetic buckle 103 can play a role of mutual attraction, thus playing a role of connection; the connecting rod 101 can play a role of fixing the first magnetic buckle 102 at the bottom of the U-shaped secondary keel 7, and at the same time can increase the distance between the first magnetic buckle 102 and the bottom of the U-shaped secondary keel 7, thereby preventing the light and shadow of the U-shaped secondary keel 7 from being projected onto the surface of the diffusion plate 3 and improving the uniformity of light; the second magnetic buckle 103 can be fixed on the top surface of the diffusion plate 3, thereby pulling the middle part of the diffusion plate 3 upward to prevent the middle part of the diffusion plate 3 from sagging due to a large load; due to the mutual attraction of the first magnetic buckle 102 and the second magnetic buckle 103, the diffusion plate 3 can be conveniently installed at the bottom of the U-shaped secondary keel 7, thus improving the installation efficiency.

[0032] Please refer to the attached Figure 10, a first printing layer 21, a second printing layer 22, a third printing layer 23 and a fourth printing layer 24 are provided on the bottom surface of the diffusion plate 3.

The density difference between the first printing layer 21 and the second printing layer 22, the density difference between the second printing layer 22 and the third printing layer 23, and the density difference between the third printing layer 23 and the fourth printing layer 24 are equal.

[0033] Specifically, the light brightness transmitted through the diffusion plate 3 can be made different by the first printing layer 21, the second printing layer 22, the third printing layer 23 and the fourth printing layer 24; since the density of the first printing layer 21 is greater than that of the second printing layer 22, the density of the second printing layer 22 is greater than that of the third printing layer 23, the density of the third printing layer 23 is greater than that of the fourth printing layer 24, and the density difference between the first printing layer 21 and the second printing layer 22, the density difference between the second printing layer 22 and the third printing layer 23, and the density difference between the third printing layer 23 and the fourth printing layer 24 are equal, a uniform gradient change of brightness can be achieved, thereby enhancing the sense of hierarchy and utilization rate.

[0035] Specifically, the installation groove 15 can play a role in installing the main air duct 16 and the auxiliary air duct 17; the main air duct 16 and the auxiliary air duct 17 can play a role in conveying air flow. The air flow is concentrated by the main air duct 16 and then dispersed by the auxiliary air duct 17; the partition plate 25 can divide the installation groove 15 into an air inlet area and an air outlet area, thus forming a convection; the air outlet 19 can play a role in installing and fixing the auxiliary air duct 17; through the two third installation holes 18, divided by the partition plate 25, the main air duct 16 is installed on one side and the first micro turbine fan 2 is installed on the other side.

[0039] Specifically, by using 6063-T5 aluminum alloy profile for the main keel 5, with a cross-sectional dimension of 30 mm in width and 50 mm in height, it has high strength and good processing performance, which can ensure the stability of the main load-bearing structure of the ceiling, and its light weight characteristic is beneficial to reducing the roof load; the diffusion plate 3 is made of PMMA optical grade sheet with a thickness of 3 mm, and the haze value ≥ 92%, which can effectively scatter light, making the light penetrate evenly and softly, improving the lighting effect and visual comfort of the ceiling. At the same time, the weather resistance and chemical stability of the PMMA material can ensure the long-term use performance of the diffusion plate 3. The diffusion plate 3 is made of PMMA optical grade sheet, which has good optical performance and environmental protection performance, with a haze value ≥ 92%, can effectively diffuse light, reduce light pollution, and its material itself is relatively environmentally friendly, meeting the requirements of green buildings for materials.

[0040] The color temperature of the LED light strip is adjustable between 3000K - 6000K, and there are 60 lamp beads per meter inside the LED light strip.

[0041] Specifically, the color temperature of the LED light strip is adjustable between 3000K and 6000K, and the light color can be adjusted according to different environments and usage requirements. While meeting the lighting needs, unnecessary energy waste is avoided, which reflects the energy-saving feature. By setting 60 lamp beads per meter inside the LED light strip, the luminous intensity and uniformity within the unit length are guaranteed, improving the overall lighting quality and the luminous effect of the ceiling. At the same time, the reasonable arrangement of the lamp beads helps to improve the light energy utilization efficiency and reduce energy consumption.

[0042] Please refer to the attached Figure 1 - attached Figure 13 , a construction method for a ceiling structure with a luminous soft film, comprising the following steps: S1. Laying out and positioning according to the design drawings, and fixing the suspender with expansion bolts; S2. After assembling the main keel 5, leveling it, with the allowable error ≤ 3mm / 2m; S3. Arranging the U-shaped secondary keels 7 at a spacing of 400mm, and when the radius of curvature > 500mm, it needs to be densified to 300mm; S4. Connecting the LED light strips according to the principle of zoning power supply, with no more than 8 LED light strips in each group circuit; S5. Heating the light-transmitting soft film 11 with a hot air gun to 60°C, then stretching and installing it, and cutting off the excess part after cooling.

[0043] Specifically, after the main keel 5 is assembled and leveled with an allowable error of ≤3 mm / 2 m, the flatness of the ceiling keel framework can be ensured, enabling components such as the U-shaped secondary keel 7 and the diffusion plate 3 to remain horizontal after installation, avoiding problems such as unevenness on the ceiling surface and wrinkles in the light-transmitting soft film 11 caused by uneven keels, guaranteeing the structural stability and overall aesthetics of the ceiling, and at the same time providing an accurate benchmark for subsequent component installation to ensure tight connection and uniform stress of each component; by arranging the U-shaped secondary keels 7 at a spacing of 400 mm, while ensuring the load-bearing capacity of the ceiling structure, uniform support can be provided for components such as the diffusion plate 3 to ensure uniform stress distribution; when the radius of curvature >500 mm, it is encrypted to 300 mm, which can meet the requirements of the ceiling curved surface shape, enhance the keel support strength in the curved surface area, and prevent problems such as deformation and sagging of components such as the diffusion plate 3 due to excessive spacing, ensuring the stability and aesthetics of the ceiling curved surface form; by wiring the LED light strips according to the principle of zoned power supply, with no more than 8 LED light strips in each circuit, excessive current in a single circuit can be avoided, ensuring the safe and stable operation of the circuit and reducing the risk of electrical faults; zoned power supply facilitates independent control and management of LED light strips in different areas, realizing functions such as zoned dimming, improving the flexibility of lighting control and energy utilization efficiency, and at the same time, when a fault occurs in a certain circuit, it is convenient for quick positioning and repair to reduce the scope of the fault impact; by heating the light-transmitting soft film 11 with a hot air gun to 60 °C and then stretching and installing it, the soft film can be softened for easy shaping, tightly fitting the ceiling structure, eliminating wrinkles and bubbles, and ensuring the installation flatness; after cooling, the excess part is cut, which can accurately control the size and boundary of the light-transmitting soft film 11, making it fit tightly with components such as the L-shaped edge-sealing keel 4, enhancing the overall aesthetics and sealing performance of the ceiling, and at the same time avoiding the accumulation of excess materials affecting the light-transmitting effect and installation stability.
