Description

Technical Field

[0001] The present invention relates to an underground space (particularly a chamber) suspended ceiling system and a construction method, belonging to the technical field of building decoration construction. Background Art

[0002] With the development of science and technology and the iteration of urbanization process, deep space optimization design and digital construction have become one of the important trends in current industrial research and future development in my country's architectural decoration field.

[0003] The research and development team of this application is committed to researching green building renovation technologies, such as converting the original tunnel-style civil air defense project for daily use in underground laboratories (such as deep underground laboratories), aiming to create a world-class underground laboratory that is "safe, efficient, technologically innovative, and green in operation."

[0004] like Figure 1 As shown, first of all, the laboratory for this project is located inside a cave with an arched ceiling. When speaking on the ground, chaotic sound waves are reflected by the curved ceiling to form orderly sound waves, which in turn form echoes. Echoes cause delays and overlaps in sound signals, thus interfering with normal speech. Therefore, only by eliminating the noise caused by echoes can work and experiments be carried out in the cave. In addition to noise, another important influencing factor in the deep earth environment is light. The cave has become dim due to the long-term lack of light. Existing solutions usually use common light sources such as chandeliers. Due to the poor lighting effect and lack of ecological atmosphere, staff who work and conduct experiments in this area for a long time will experience visual fatigue and even vision loss.

[0020] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0023] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7As shown, an underground space ceiling system includes multiple frame components, multiple square keel frames 20, multiple hanging rod components 30, multiple decorative panels and multiple light strips 90; multiple frame components are fixed on the top wall of the cavern in parallel along the length direction of the cavern, and the frame component is composed of two symmetrically arranged arc-shaped frame structures 10 connected together; at least one layer of sound-absorbing components I is installed in the arc-shaped frame structure; multiple square keel frames 20 are arranged in parallel below the arc-shaped frame structure 10 along the width direction of the cavern, and each row of keel frames is fixed on the top wall of the cavern in parallel along the length direction of the cavern. The height of the skeleton 20 is not exactly the same, which is used to disperse sound waves; one end of the suspension component 30 is connected to the keel frame 20, and the other end is connected to the arc frame structure 10, which is used to hang the keel frame 20 on the top of the chamber; the decorative panel is installed on the keel frame 20, and at least one layer of sound-absorbing component II70 is installed between the decorative panel and the keel frame 20; multiple light strips 90 are fixed on the decorative panel in parallel along the length direction of the chamber; at least one light strip is arranged at the junction of the two arc frame structures, thereby forming a "slit-like" lighting atmosphere.

[0025] It should be noted that many of the cavern's exterior walls are made of rock, which is not very hard. If the frame structure is directly fastened to the cavern with fasteners, it is very likely to fall. Instead, holes can be drilled in the rock, anchor rods placed in the holes, and high-strength cement slurry is injected into the holes with the anchor rods to secure the anchor rods to the cavern's exterior walls. Once the entire cavern's top wall is covered with anchor rods, the frame structure and the anchor rods can be fixed together, typically by welding.

[0026] The above-mentioned arc frame structure is further described below.

[0027] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 As shown, the arc frame structure 10 is mainly composed of horizontal bars, vertical bars and arc bars welded together; the arc frame structure 10 is divided into two upper and lower installation spaces, and each installation space is provided with a layer of sound absorbing component I60.

[0028] It should be noted that the horizontal bars, vertical bars and arc bars in the arc frame structure 10 are all made of high-strength hollow steel pipes to further reduce the weight of the entire arc frame structure 10. The steel pipes can be round steel pipes or square steel pipes.

[0029] Further solutions, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7As shown, the height of the upper installation space in the arc-shaped frame structure 10 is smaller than the height of the lower installation space, so that an air layer is formed between the upper and lower layers of the sound-absorbing components I60; or, the height of the upper installation space in the arc-shaped frame structure 10 is greater than the height of the lower installation space, so that an air layer is formed between the upper and lower layers of the sound-absorbing components I60.

[0030] It should be noted that the arc frame structure 10 can also be provided with three or four layers of installation space, which will undoubtedly increase the weight of the arc frame structure. Under the premise of reducing the weight of the arc frame structure as much as possible, generally two layers of installation space are sufficient.

[0031] In a further solution, steel mesh is welded to the bottom surfaces of the upper and lower installation spaces, and the sound-absorbing component I is laid on the steel mesh.

[0032] In the preferred embodiment, both sound-absorbing components I 60 and II 70 are made of glass wool. The sound-absorbing effect of glass wool is primarily reflected in its ability to effectively absorb sound waves and reduce noise. Glass wool's internal fibers are fluffy and interwoven, with numerous tiny pores, making it a typical porous sound-absorbing material with excellent sound absorption properties. When sound waves encounter glass wool, they enter these pores and undergo multiple reflections, refractions, and scattering. During these processes, some of the sound waves are absorbed, reducing reflection and propagation. Through this sound-absorbing mechanism, glass wool can effectively reduce noise levels within buildings and the surrounding environment.

[0033] Further solutions, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 As shown, a plurality of counter-support rods 80 are welded between the keel frame 20 and the curved frame structure 10. The counter-support rods 80 can be made of hollow round steel tubes or square steel tubes. The main function of the counter-support rods 80 is to enhance the stability of the suspended ceiling and prevent the suspended ceiling from deformation due to changes in air pressure or negative wind pressure.

[0034] The above-mentioned decorative panel is further described below.

[0035] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 As shown, multiple decorative panels are divided into multiple decorative panels I40 and multiple decorative panels II50; multiple decorative panels I40 are installed on part of the keel frame 20, and the decorative panels I40 are used to seal the keel frame 20 on the one hand, and to seal the gap between the upper and lower adjacent two keel frames 20 on the other hand; multiple decorative panels II50 are installed on the remaining keel frame 20, and the decorative panels II50 are also overlapped with the adjacent and upper keel frame 20.

[0036] It should be noted that both decorative panel I40 and decorative panel II50 are made of aluminum plates, which have the advantages of light weight and high strength.

[0037] Further solutions, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 As shown, a cavity is formed between the decorative panel II 50 and the adjacent keel frame 20 located above, and a light strip 90 is installed on the decorative panel I 40 in the cavity; Both decorative panels I40 and II50 are porous panels, which are used for sound absorption and lighting. Different lighting atmospheres can be created by opening holes of different sizes and arrangements on decorative panel II50.

[0038] The preferred solution is Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 As shown, five keel frames 20 of different heights are arranged side by side along the width direction of the cavern chamber, namely the first keel frame, the second keel frame, the third keel frame, the fourth keel frame and the fifth keel frame from left to right, the first keel frame is the lowest, the fifth keel frame is the highest, the third keel frame is higher than the fourth keel frame, and the fourth keel frame is higher than the second keel frame; the second keel frame, the third keel frame and the fifth keel frame are each installed with a decorative panel I40, and the first keel frame and the second keel frame as well as the fourth keel frame and the fifth keel frame are each installed with a decorative panel II50; the cavity formed by the decorative panel I40 on the second keel frame and the decorative panel II50 below it and the cavity formed by the decorative panel I40 on the fifth keel frame and the decorative panel II50 below it are both provided with a plurality of light strips 90; a light strip 90 is installed on the second keel frame below the decorative panel I40 on the third keel frame, and a light strip 90 is installed on the fourth keel frame below the decorative panel I40 on the third keel frame.

[0039] It should be noted that only five keel frames are provided in the embodiment. Of course, in actual use, it is not limited to five keel frames, and it can also be six, seven or even more.

[0040] The above-mentioned keel frame is further explained below.

[0041] like Figure 9 、 Figure 10As shown, the keel framework includes two main keels 1, two secondary keels 2, and multiple overlapping components 3; the two main keels are arranged side by side in the same plane at a predetermined interval; the two main keels 1 are arranged side by side in the same plane at a predetermined interval; the two secondary keels 2 are arranged side by side in the same plane at a predetermined interval, and the two secondary keels 2 are located below the two main keels 1; the multiple overlapping components 3 are respectively arranged at the intersections of the main and secondary keels 1 and 2, and the overlapping component 3 is configured to fix and release the fixation between the main and secondary keels 1 and 2.

[0042] The specific structure of the above overlapping component will be further described below.

[0043] As Figure 11 shown, the overlapping component 3 has an inverted U-shaped structure for clamping onto the main keel 1; each of the lower regions of the two side faces of the overlapping component 3 is provided with a pair of oppositely arranged insertion slots 301, and the top part of the secondary keel 2 is inserted into the two oppositely arranged insertion slots 301 simultaneously.

[0044] A further solution, as [[ID=1,6]] Figure 11 shown, at least one threaded hole 303 is provided on the side face and / or the top plane of the overlapping component 3, and the threaded hole 303 cooperates with a setscrew to tightly fix the main keel 1 in the overlapping component 3.

[0045] A preferred solution, as Figure 11 [[ID=,22]]shown, at least one arc-shaped groove 304 is provided at the part of the insertion slot 301 in contact with the secondary keel 2, for reducing local stress concentration and enhancing the strength of the overlapping component 3.

[0046] The specific connection structure between the above decorative panel I, decorative panel II and the secondary keel will be further described below.

[0047] The bottom part of the secondary keel 2 has a hook-shaped structure 202; one side edge of the decorative panel I is provided with an L-shaped structure 501, and the L-shaped structure 501 overlaps on the hook-shaped structure 202; the other side edge of the decorative panel I is provided with an inverted hook-shaped structure 502, and the inverted hook-shaped structure 502 is snap-connected with the hook-shaped structure 202; the decorative panel I can move linearly along the length direction of the secondary keel 2, and vertically moving the decorative panel I upwards can release the snap-connection relationship between the two, and horizontally moving the decorative panel I can remove it from the two secondary keels 2.

[0048] One side of the decorative plate II is provided with two “┏” structures for respectively snapping onto the corresponding secondary keels 2 ; the other side of the decorative plate II is provided with two “┓” structures for respectively snapping onto the corresponding secondary keels 2 .

[0049] Further solutions, such as Figure 12 、 Figure 13 As shown, the decorative panels I in two adjacent parallel-arranged ceiling structure units are connected in such a way that the inverted hook-shaped structure 502 of one decorative panel I is snapped together with the hook-shaped structure 202 of the secondary keel 2, and the "┓" structure 501 of the other decorative panel I is overlapped on the inverted hook-shaped structure 502.

[0050] The specific structure of the above-mentioned hanger bar assembly is further described below.

[0051] like Figure 9 、 Figure 10 As shown, the suspension rod assembly 4 consists of a hook 401 and a suspension rod 402; external threads are provided at both ends of the suspension rod 402 in the length direction, the suspension rod 402 is inserted into the through hole at the top of the hook 401, and the suspension rod 402 and the hook 401 are fixed together by fastening with a nut; the main keel 1 is inserted into the hook of the hook 401, and the hook of the hook 401 is penetrated by a bolt fastened by a nut or a pin fastened by a cotter pin at the position above the main keel 1, so as to limit the upward movement of the main keel 1.

[0052] It should be noted that the accompanying drawings show a preferred embodiment, that is, the main keel 1 generally adopts a C-shaped structure, the auxiliary keel 2 generally adopts a Z-shaped structure, and the top part of the auxiliary keel 2 is inserted into the insertion groove 301 with a "┓" structure in a "┓" structure 201.

[0053] like Figure 6 As shown, the construction process of the above-mentioned chamber ceiling system is given below: Step 1: Clean the base: sweep away debris, remove bulges, perform deep dust removal, and inspect and accept to ensure that the walls of the chamber are solid and flat; Step 2: Build the steel frame: Fix 40*40 hot-dip galvanized square tubes along the length of the curved wall on the top surface as the steel frame; Step 3: Laying glass wool: Lay double layers of 50mm thick centrifugal glass wool in the steel frame in step 2, supported by steel mesh underneath, leaving a 40mm cavity between the two layers of glass wool; Step 4: Build the ceiling steel frame: Use the main keel and the auxiliary keel to overlap the ceiling frame, and add counter supports to fix it; Step 5.

Step 6. Install the lighting: Install the light strip on the decorative panel I, and finally buckle the decorative panel II.

[0054] In summary, the present invention provides a ceiling system for a chamber, which achieves the following functions and effects: 1. By constructing a keel frame of varying heights to disperse the sound waves, the ordered sound waves are broken up and the echo is reduced; 2. Glass wool is filled in the frame structure and decorative panels, which can effectively reduce the noise level inside the building and the surrounding environment; 3. There are multiple anti-support rods welded between the keel frame and the frame structure. Their main function is to enhance the stability of the ceiling and prevent the ceiling from being deformed due to changes in air pressure or negative wind pressure. 4. The main and auxiliary keels are connected together by overlapping parts, which enables the rapid disassembly and assembly of the main and auxiliary keels; the decorative panels are movably connected to the auxiliary keels, which enables the rapid disassembly and assembly of the decorative panels without damaging them; 5. If Figure 8 As shown, a light strip is arranged in the middle of the suspended ceiling to form a "slit sky" lighting atmosphere. The lighting design of the "slit sky" imitates the visual effect of the narrow sky in nature, creating a unique light and shadow experience; the "slit sky" lighting design can add a mysterious and tranquil atmosphere to the interior space, making people have a special emotional experience when entering the space; the "slit sky" lighting design can enhance the aesthetic effect of the space, making it more artistic and design-oriented; the "slit sky" lighting design can give people a feeling of space extension, making the interior space appear more spacious and transparent.

[0055] 6. If Figure 8 As shown, most of the light strips are hidden in the decorative panel II, and holes of different sizes and arrangements are opened on the decorative panel II; Improved lighting effects: Carefully designed holes can achieve indirect lighting, making the light softer and avoiding the glare of direct sunlight. At the same time, the distribution and size of the holes can adjust the diffusion angle of the light to achieve the purpose of uniform lighting.

[0056] Enhance spatial layering: The design of holes can break the monotony of the ceiling and add visual depth and layering. The arrangement and combination of holes of different sizes and shapes can create unique light and shadow effects, enhancing the artistic atmosphere of the space.

[0057] Energy conservation: Controlling the direction and range of light through the holes can reduce unnecessary light pollution and improve lighting efficiency. For example, light can be concentrated on the areas that need to be illuminated, avoiding waste in places where it is not needed.

[0058] Hidden lighting: The holes can be used as outlets for LED light strips, so that the lamps themselves are not exposed, keeping the ceiling neat and beautiful. This concealed lighting method not only enhances the overall sense of space, but also increases the creativity of the design.
