Description

Technical Field

[0001] This utility model relates to a sound-absorbing ceiling structure unit and ceiling system for underground spaces (especially chambers), belonging to the field of building decoration and construction technology. Background Technology

[0002] With the advancement of technology and the iterative process of urbanization, deep-earth space optimization design and digital construction have become one of the important trends in the current industrial research and future development of my country's building decoration industry.

[0003] The research team behind this application is dedicated to studying the renovation and decoration of deep-earth spaces, such as converting former tunnel-style civil defense projects for daily use in underground laboratories (e.g., deep-earth laboratories). Figure 1 As shown, the laboratory in this project is located inside a cave. Such projects commonly suffer from noise interference, primarily because the cave ceiling has an arched structure. When speaking from the ground, chaotic sound waves are reflected by the arched ceiling, forming ordered sound waves and creating echoes. These echoes cause delays and overlaps in sound signals, interfering with normal speech. Therefore, only by eliminating the noise caused by echoes can office work and experiments be conducted inside the cave. Currently, the industry mainly uses sound-absorbing materials in the ceiling; however, due to the unique structure of the cave, sound waves tend to concentrate, making conventional sound-absorbing solutions ineffective. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a sound-absorbing ceiling structure unit and ceiling system for underground spaces. It has excellent sound absorption properties and disperses continuous sound waves through staggered ceiling structures, effectively isolating noise transmission and improving the internal sound control effect.

[0005] This utility model is achieved according to the following technical solution: In a first aspect, this utility model provides a sound-absorbing ceiling structure unit for underground spaces, comprising: An arc-shaped frame structure is fixed to the top wall of the chamber; at least one layer of sound-absorbing components I is installed in the frame structure; Multiple square keel frames are arranged side by side along the width of the chamber, with each row of keel frames having a different height to disperse sound waves; Multiple suspension rod components, one end of which is connected to the keel frame and the other end of which is connected to the frame structure, are used to suspend the keel frame from the top of the chamber; Multiple decorative panels are installed on the keel frame, and at least one layer of sound-absorbing component II is installed between the decorative panels and the keel frame.

[0006] In some embodiments, the frame structure is mainly composed of horizontal bars, vertical bars and arc bars welded together; the frame structure is divided into upper and lower installation spaces, and each installation space is provided with a layer of the sound-absorbing component I.

[0007] In some embodiments, the height of the upper mounting space in the frame structure is less than the height of the lower mounting space, so that an air layer is formed between the upper and lower sound-absorbing components I; or, the height of the upper mounting space in the frame structure is greater than the height of the lower mounting space, so that an air layer is formed between the upper and lower sound-absorbing components I.

[0008] In some embodiments, the bottom surfaces of both the upper and lower installation spaces are fixed with wire mesh, and the sound-absorbing component I is laid on the wire mesh.

[0009] In some embodiments, at least one anti-support rod is fixed between the keel frame and the frame structure.

[0010] In some embodiments, the multiple decorative panels are divided into: Multiple decorative panels I are installed on part of the keel frame. These decorative panels I are used to seal the keel frame on one hand and to seal the gap between the top and bottom of two adjacent keel frames on the other hand. Multiple decorative panels II are installed on the remaining keel frame, and these decorative panels II also overlap with the adjacent and upper keel frame.

[0011] In some embodiments, a cavity is formed between the decorative panel II and the adjacent and upper keel frame, and a light strip is installed on the decorative panel I in the cavity; both the decorative panel I and the decorative panel II are perforated panels.

[0012] In some embodiments, five keel frames of different heights are arranged side by side along the width of the chamber, from left to right as the first keel frame, the second keel frame, the third keel frame, the fourth keel frame, and the fifth keel frame. 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. A decorative panel I is installed on each of the second, third, and fifth keel frames, and a decorative panel II is installed on each of the first, second, fourth, and fifth keel frames.

[0013] In some embodiments, the keel frame mainly consists of a main keel, a secondary keel, and an overlapping component that connects the main and secondary keels together; the suspension rod component mainly consists of a hook and a rod; the hook hooks onto the main keel, and one end of the rod is connected to the frame structure, while the other end is connected to the hook.

[0014] Secondly, this utility model provides a ceiling system, including multiple of the above-mentioned underground space sound-absorbing ceiling structural units.

[0015] The beneficial effects of this utility model are: 1. By constructing a keel frame of varying heights to disperse sound waves, the ordered sound waves are broken up, thus reducing echoes. 2. Glass wool is filled in both the frame structure and the decorative panels. Glass wool can effectively reduce the noise level inside the building and in the surrounding environment. 3. Multiple anti-support rods are 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 deforming under changes in air pressure or negative wind pressure. Attached Figure Description

[0019] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a spatial sound-absorbing ceiling structure unit includes an arc-shaped frame structure 10, multiple square keel frames 20, multiple suspension rod components 30, and multiple decorative panels. The arc-shaped frame structure 10 is fixed to the top wall of the chamber. At least one layer of sound-absorbing components I is installed in the frame structure 10. Multiple square keel frames 20 are arranged side by side along the width of the chamber, and the height of each row of keel frames 20 is not exactly the same, which is used to disperse sound waves. One end of the suspension rod component 30 is connected to the keel frame 20, and the other end is connected to the frame structure 10, which is used to suspend the keel frame 20 from the top of the chamber. The decorative panels are installed on the keel frames 20, and at least one layer of sound-absorbing components II 70 is installed between the decorative panels and the keel frames 20.

[0024] It should be noted that much of the outer wall of the chamber is made of rock, which is not very hard. If the frame structure is directly fixed to the chamber with fasteners, there is a high risk of it falling. Instead, holes can be drilled in the rock first, then anchor bolts can be placed in the holes. Finally, high-strength cement grout can be injected into the holes containing the anchor bolts to secure them to the outer wall of the chamber. Once the entire top wall of the chamber is covered with anchor bolts, the frame structure can be fixed to the anchor bolts directly by welding.

[0025] The framework structure described above will be further explained below.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the frame structure 10 is mainly composed of horizontal bars, vertical bars and arc bars welded together; the frame structure 10 is divided into upper and lower installation spaces, and each installation space is equipped with a layer of sound-absorbing component I60.

[0027] It should be noted that the horizontal bars, vertical bars, and curved bars in the frame structure 10 are all made of high-strength hollow steel pipes to further reduce the weight of the entire frame structure 10. The steel pipes can be round steel pipes or square steel pipes.

[0028] Further options, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the height of the upper installation space in the frame structure 10 is less than the height of the lower installation space, so that an air layer is formed between the upper and lower sound-absorbing components I60; or, the height of the upper installation space in the 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 sound-absorbing components I60.

[0029] It should be noted that the frame structure 10 can also be set with three or four layers of installation space, which will undoubtedly increase the weight of the frame structure. Under the premise of minimizing the weight of the frame structure, it is generally sufficient to set two layers of installation space.

[0030] A further proposed solution involves welding wire mesh to the bottom surfaces of both the upper and lower installation spaces, with the sound-absorbing component I laid on top of the wire mesh.

[0031] In the preferred embodiment, both sound-absorbing component I60 and sound-absorbing component II70 are made of glass wool. The sound-absorbing effect of glass wool is mainly reflected in its ability to effectively absorb sound waves and reduce noise. The internal fibers of glass wool are loosely interwoven, containing numerous tiny pores, making it a typical porous sound-absorbing material with excellent sound absorption characteristics. When sound waves encounter glass wool, they enter these pores and undergo multiple reflections, refractions, and scattering processes. During these processes, some sound waves are absorbed, thereby reducing sound wave reflection and propagation. Through this sound-absorbing mechanism, glass wool can effectively reduce noise levels inside the building and in the surrounding environment.

[0032] Further options, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, multiple counter-support rods 80 are welded between the keel frame 20 and the frame structure 10. The counter-support rods 80 can be hollow round steel tubes or square steel tubes. The main function of the counter-support rods 80 is to enhance the stability of the ceiling and prevent the ceiling from deforming under changes in air pressure or negative wind pressure.

[0033] The following provides further explanation of the aforementioned decorative panels.

[0034] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the multiple decorative panels are divided into multiple decorative panels I 40 and multiple decorative panels II 50; multiple decorative panels I 40 are installed on part of the keel frame 20, and the decorative panels I 40 are used to seal the keel frame 20 on the one hand and to seal the gap between the upper and lower parts of two adjacent keel frames 20 on the other hand; multiple decorative panels II 50 are installed on the remaining keel frame 20, and the decorative panels II 50 also overlap with the adjacent and upper keel frame 20.

[0035] It should be noted that both decorative panel I40 and decorative panel II50 are made of aluminum sheet, which has the advantages of being lightweight and having high strength.

[0036] Further options, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a cavity is formed between the decorative panel II 50 and the adjacent and upper keel frame 20, and a light strip 90 is installed on the decorative panel I 40 in the cavity; Both decorative panel I40 and decorative panel II50 are perforated panels, used for sound absorption on one hand and for lighting on the other.

[0037] Preferred solutions, such as Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in the figure, five dragon skeletons 20 with different heights are arranged side by side along the width direction of the chamber. From left to right, they are the first dragon skeleton, the second dragon skeleton, the third dragon skeleton, the fourth dragon skeleton, and the fifth dragon skeleton. The first dragon skeleton is the lowest, the fifth dragon skeleton is the highest, the third dragon skeleton is higher than the fourth dragon skeleton, and the fourth dragon skeleton is higher than the second dragon skeleton. A decorative panel I 40 is installed on each of the second dragon skeleton, the third dragon skeleton, and the fifth dragon skeleton, and a decorative panel II 50 is installed on each of the first dragon skeleton and the second dragon skeleton, as well as the fourth dragon skeleton and the fifth dragon skeleton.

[0038] It should be noted that only five dragon skeletons are given in the embodiment. Of course, in actual use, it is not limited to five dragon skeletons, and it can also be six, seven or even more.

[0039] The above-mentioned dragon skeleton will be further described below.

[0040] It should be noted here that the dragon skeleton is an existing mature technology, and many structures can be used. In actual use, it is not limited to the following structure. Moreover, the dragon skeleton is not the design key point of this technical solution, so only a simple introduction will be given and no detailed description will be made.

[0041] As Figure 9 shown in the figure, the dragon skeleton 20 mainly consists of a main keel 201, a secondary keel 202, and a lapping component 203 that connects the main and secondary keels together; the hanging bar component 30 mainly consists of a hook 302 and a hanging bar 301; the hook 302 hooks the main keel 201, and one end of the hanging bar 301 is connected to the frame structure 10, and the other end is connected to the hook 302.

[0042] Specific scheme: The dragon skeleton 20 includes two main keels 201, two secondary keels 202, and multiple lapping components 203; the two main keels 301 are arranged side by side at a predetermined interval in the same plane; the two secondary keels 302 are arranged side by side at a predetermined interval in the same plane, and the two secondary keels 302 are located below the two main keels 301; multiple lapping components 302 are respectively arranged at the intersections of the main and secondary keels. The lapping component 203 is in a "冂" shape structure and is used to be clamped on the main keel 301; a pair of insertion slots are respectively opened in the lower regions of the two side facades of the lapping component 203, and the top part of the secondary keel 202 is inserted into the two relatively arranged insertion slots at the same time. One side of the decorative panel I 40 is set as a "┓" structure, and the other side is set as an inverted hook structure, which is used to be clamped on the two secondary keels 202; one side of the decorative panel II 50 is set as two "┏" structures, which are respectively used to be clamped on the corresponding secondary keels 202; the other side of the decorative panel II 50 is set as two "┓" structures, which are respectively used to be clamped on the corresponding secondary keels 202.

[0043] The main keel 201 generally adopts a C-shaped structure, and the secondary keel 202 generally adopts a Z-shaped structure. The top part of the secondary keel 202 is inserted into the insertion groove with a "┓" structure. The hanger rod 301 passes through the through hole at the top of the hook 302 and is fixed together with the hook 302 by tightening the nut. The main keel 201 passes through the hook of the hook 302. The hook of the hook 302 has a bolt that is tightened by a nut or a pin that is tightened by a cotter pin passing through the hook above the main keel 201, which limits the upward movement of the main keel 201.

[0044] The construction process of the above-mentioned spatial sound-absorbing ceiling structural unit is given below: like Figure 6 As shown, the construction sequence is: cleaning the base layer → constructing the steel frame → laying glass wool → constructing the ceiling steel frame → installing sound-absorbing aluminum panels. The specific process is as follows: 1. Clean the base layer: sweep away debris, remove bumps, perform deep dust removal, and inspect and accept the work to ensure that the base layer is solid and flat; 2. Steel frame construction: 40*40 hot-dip galvanized square tubes are fixed inside the curved wall as a steel frame; 3. Glass wool laying: The inside of the square tube is fully laid with double layers of 50 mm thick centrifugal glass wool, supported by wire mesh at the bottom, with a 40 mm cavity in the middle; 4. Ceiling steel frame construction: The ceiling frame is constructed by overlapping light steel main keel and secondary keel, with additional counter bracing for fixation; 5. Sound-absorbing aluminum panel installation: Custom-made sound-absorbing aluminum panels are installed, and centrifugal glass wool is laid again to further reduce the reflection of sound on the top surface.
