Description

Technical Field

[0001] This application relates to the technical field of sound-absorbing ceilings, and in particular to a sound-absorbing ceiling structure for theaters and its construction method. Background Technology

[0002] Theaters and similar venues often host events such as musicals and concerts. For these events, audiences need to hear the performers' voices and the details of the music clearly. Therefore, it is essential to install sound-absorbing ceilings in theaters.

[0003] First, sound-absorbing ceilings effectively reduce echoes and reverberation, improving sound quality and clarity. Second, they reduce noise and interference, enhancing audience comfort and concentration. In a quiet and comfortable environment, audiences are more likely to immerse themselves in the performance and enjoy the artwork. Furthermore, sound-absorbing ceilings help control sound propagation within the theater, minimizing disturbance to the surrounding environment. This is also crucial for the community where the theater is located and for nearby residents, as it reduces noise pollution and improves the comfort of the surrounding environment.

[0004] Regarding the aforementioned technologies, existing sound-absorbing ceilings are typically complex to install, and theater spaces are large, making installation inefficient. Summary of the Invention

[0005] To improve the installation efficiency of sound-absorbing ceilings in theaters, this application provides a sound-absorbing ceiling structure for theaters and its construction method.

[0006] Firstly, the theater sound-absorbing ceiling structure provided in this application adopts the following technical solution: A sound-absorbing ceiling structure for a theater and its construction method are disclosed. The structure includes several vertical hangers connected to the theater roof. Horizontal main keels are connected to the bottom of each hanger. The main keels are parallel to each other. A sound-absorbing structure is provided at the bottom of each main keel. The sound-absorbing structure includes secondary keels, which are horizontal and fixed perpendicularly to the main keels. The secondary keels connected to the walls at both ends are C-shaped steel, and the remaining intermediate secondary keels are I-beams. Interlocking panels are provided between adjacent secondary keels. The interlocking panels are slidably connected to the secondary keels. A cavity is provided within the interlocking panel, and sound-absorbing cotton is placed inside the cavity.

[0007] By adopting the above technical solution, the main keel is installed after the vertical hanger is positioned, and then the secondary keel is installed. The flat side of the C-shaped steel is fixed to the wall. The grooves of the C-shaped steel and the I-beam are opposite each other for installing splicing panels. Sound-absorbing cotton is filled into the cavity of the splicing panel to achieve the sound absorption effect. The splicing panel can slide along the secondary keel, be aligned one by one, and spliced ​​together for installation. For theaters with a large area, the installation of sound-absorbing ceiling can be achieved more quickly, and it is also more convenient than the traditional structure.

[0008] Optionally, each of the splicing panels has a mating hole on its interlocking side, and the splicing panel has a mating rod that matches the mating hole.

[0009] By adopting the above technical solution, the connecting rod is inserted into the connecting hole, which can be positioned when the two splicing panels are joined, ensuring the accuracy of the installation position of the two splicing panels. If the alignment cannot be achieved, it may be that the splicing panels are unqualified or the installation positions of the main keel and secondary keel are misaligned. After solving the problem, the installation can continue to ensure the installation effect of the sound-absorbing ceiling.

[0010] Optionally, a pressing plate is provided in the cavity of the splicing plate. The pressing plate is located at the bottom of the sound-absorbing cotton. The opening height of the cavity is greater than the thickness of the sound-absorbing cotton and the pressing plate. The splicing plate is provided with an abutting component for pressing the pressing plate upward.

[0011] By adopting the above technical solution, the cavity opening height is greater than the thickness of the sound-absorbing cotton and the pressing plate, which facilitates the filling of the sound-absorbing cotton. After filling, the pressing plate is pressed and limited by the pressing component to fix the sound-absorbing cotton.

[0012] Optionally, the abutting component includes a pressing block, the splicing plate has a pressing groove that communicates with the cavity, the bottom of the pressing block is provided with a compression spring, when the pressing block is fully placed in the pressing groove, the compression spring is in a compressed state, and the splicing plate is provided with a limiting member to control the position of the pressing block.

[0013] By adopting the above technical solution, the limiting component limits the pressing block. When the pressing block is fully placed in the pressing groove, the compression spring is in a compressed state. When the limiting component does not limit the pressing block, the compression spring provides the pressing block with an upward movement tendency. The pressing block moves upward, thereby fixing the sound-absorbing cotton above.

[0014] Optionally, the limiting member includes a top rod, which is slidably connected to the mating hole of the splicing plate. The end of the top rod is provided with a pressure block, which is disposed above the pressing block and slides horizontally along the cavity.

[0015] By adopting the above technical solution, the pressure block is pressed on top of the clamping block before installation. When two adjacent splicing plates are spliced, the docking rod is inserted into the docking hole. The docking rod pushes the top rod to slide inward along the docking hole, and the pressure block breaks the top rod and moves, thereby moving the pressure block away from the clamping block. This achieves the fixation of the sound-absorbing cotton at the same time as the docking installation, further improving efficiency.

[0016] Optionally, a layer of microporous patterned mineral wool board is adhered to the bottom of the splicing plate.

[0017] By adopting the above technical solutions, mineral wool boards use mineral wool as the main raw material. Mineral wool has well-developed micropores, which reduce sound wave reflection, eliminate echoes, and isolate noise transmitted from the floor. Mineral wool sound-absorbing boards have superior properties such as sound absorption, non-combustibility, heat insulation, and decoration. They can control and adjust reverberation time, improve indoor sound quality, and reduce noise. At the same time, the non-combustible properties of this product can meet the fire protection requirements of building design.

[0018] Optionally, each of the main keels is provided with a number of anti-seismic holes.

[0019] By adopting the above technical solution, the opening of anti-seismic holes in the main keel can improve the structural stability of the ceiling, giving the ceiling better seismic resistance and torsional resistance.

[0020] Secondly, this application provides a construction method for a theater sound-absorbing ceiling structure, including the following steps: S1: Positioning, drilling, installing vertical hangers, and installing the main keel; S2: Install sound-absorbing structure; S3: Repairing or mending seams.

[0021] By adopting the above technical solution, the main roof joists are first installed, ensuring their accurate positioning, levelness, and ability to withstand the weight of the roof and the influence of the external environment. During installation, appropriate connectors and fixing equipment are used to ensure the stability and safety of the structure. Then, the sound-absorbing structure is installed. After installation, the sound-absorbing ceiling needs adjustment and refinement, including checking the secure installation of the sound-absorbing structure, the stability of the hangers, and whether the sound absorption effect meets design requirements. Simultaneously, the sound-absorbing ceiling needs cleaning and surface treatment, including filling gaps and making repairs, to ensure that the appearance and performance of the sound-absorbing ceiling meet the expected requirements.

[0022] Optionally, in S1, a layer of fiberglass sound-absorbing board is pasted on the theater roof before positioning and drilling.

[0023] By adopting the above technical solutions, fiberglass sound-absorbing panels hardly absorb moisture from the air and do not cause capillary action. Because of their non-hygroscopic properties, they do not easily create the natural environmental conditions required for the reproduction of microorganisms, thus inhibiting the growth of microorganisms and preventing yellowing and mold growth. At the same time, they can reduce room noise mixing and isolate the spread of noise.

[0024] Optionally, in S2, the structure within the sound-absorbing structure is pre-filled and installed before installation.

[0025] By adopting the above technical solution, sound-absorbing cotton and sound-absorbing panels can be pre-filled into the splicing panel, thereby reducing the inconvenience of operation during installation.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. After the main keel is installed by positioning the vertical hanger rod, the secondary keel is installed. The flat side of the C-shaped steel is fixed to the wall. The grooves of the C-shaped steel and the I-beam are opposite each other for installing the splicing panels. The sound-absorbing cotton is filled in the cavity of the splicing panel to achieve the sound absorption effect. The splicing panel can slide along the secondary keel. They can be aligned one by one and spliced ​​together. For theaters with a large area, the installation of the sound-absorbing ceiling can be achieved more quickly, and it is more convenient than the traditional structure. 2. Inserting the connecting rod into the connecting hole can position the two splicing panels when they are joined, ensuring the accuracy of their installation position. If the connection cannot be made, it may be due to the splicing panels being unqualified or the main keel and secondary keel being misaligned. Resolve the problem before continuing the installation to ensure the sound-absorbing ceiling installation effect. 3. The cavity opening height is greater than the thickness of the sound-absorbing cotton and the pressing plate, which facilitates the filling of the sound-absorbing cotton. After filling, the pressing plate is pressed and limited by the pressing component to fix the sound-absorbing cotton. Attached Figure Description

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a sound-absorbing ceiling structure for theaters.

[0032] Reference Figure 1 A sound-absorbing ceiling structure for a theater includes several vertical hangers 1 connected to the theater roof. Each row of vertical hangers 1 is evenly arranged. The bottom of each vertical hanger 1 is connected to a horizontal main keel 2. The main keel 2 is made of light steel. The ends of the main keel 2 need to be fixed to the wall. Each main keel 2 has several anti-vibration holes 21. The main keels 2 are parallel to each other. The bottom of the main keel 2 is provided with a sound-absorbing structure 3. The vertical hangers 1 are positioned to install the main keel 2. The sound-absorbing structure 3 achieves the sound absorption effect.

[0033] Reference Figure 1The sound-absorbing structure 3 includes secondary keels 31, which are horizontal and fixed vertically to the main keel 2. The secondary keels 31 connected to the wall at both ends are C-shaped steel, with one side of the C-shaped steel fixed to the wall. The grooves of the C-shaped steel and the I-beams are opposite each other. The remaining intermediate secondary keels 31 are I-beams. Interlocking splicing plates 32 are provided between adjacent secondary keels 31. A layer of microporous patterned mineral wool board 5 is adhered to the bottom of the splicing plate 32. The mineral wool sound-absorbing board has superior properties such as sound absorption, non-combustibility, heat insulation, and decoration. It can control and adjust reverberation time, improve indoor sound quality, and reduce noise. The splicing plates 32 are slidably connected to the secondary keels 31 on both sides. The splicing plates 32 have butt holes on their interlocking sides, which are horizontally opened at the splicing points. At the midpoint of the two sides of the splicing plate 32, the splicing plate 32 is equipped with a connecting rod 322 that matches the connecting hole. The connecting rod 322 can be inserted into the connecting hole of the two adjacent splicing plates 32, and can be positioned when the two splicing plates 32 are joined to ensure the accuracy of the installation position of the two splicing plates 32. If the alignment cannot be achieved, it may be that the splicing plate 32 is unqualified or the installation position of the main keel 2 and the secondary keel 31 is misaligned. After solving the problem, continue the installation to ensure the installation effect of the sound-absorbing ceiling. The splicing plate 32 can slide along the secondary keel 31, and be aligned and spliced ​​one by one. For theaters with a large area, the installation of the sound-absorbing ceiling can be achieved more quickly, and it is more convenient than the traditional structure.

[0034] Reference Figure 1 The splicing plate 32 has a cavity, and sound-absorbing cotton 321 is placed inside the cavity. The sound-absorbing cotton 321 is made of polyester fiber. A pressing plate 323 is placed inside the cavity of the splicing plate 32, and the pressing plate 323 is located at the bottom of the sound-absorbing cotton 321. The opening height of the cavity is greater than the thickness of the sound-absorbing cotton 321 and the pressing plate 323. The splicing plate 32 has an abutting component for pressing the pressing plate 323 upward. The opening height of the cavity is greater than the thickness of the sound-absorbing cotton 321 and the pressing plate 323 to facilitate the filling of the sound-absorbing cotton 321. After filling, the pressing plate 323 is pressed and limited by the abutting component to fix the sound-absorbing cotton 321.

[0035] Reference Figure 1 and Figure 2The abutment assembly includes two square abutment blocks 4. The splicing plate 32 has two abutment grooves communicating with the cavity for placing the abutment blocks 4. Each abutment block 4 has a compression spring 41 at its bottom. When the abutment block 4 is fully placed in the abutment groove, the compression spring 41 is compressed. The splicing plate 32 has a limiting component for controlling the position of the abutment blocks 4. The limiting component includes a push rod 42, which is slidably connected to the mating hole of the splicing plate 32. A pressure block 43 is provided at the end of the push rod 42. The length of the pressure block 43 is designed to simultaneously press down on both abutment blocks 4, and the width of the pressure block 43 is less than the distance between the inner end of one abutment block 4 and the end of the cavity. The pressure block 43 is positioned above the clamping block 4 and slides horizontally along the cavity. Before installation, the pressure block 43 is pressed against the clamping block 4. When two adjacent splicing plates 32 are spliced, the docking rod 322 is inserted into the docking hole. The docking rod 322 pushes the top rod 42 to slide inward along the docking hole. The pressure block 43 moves with the top rod 42, thereby moving the pressure block 43 away from the clamping block 4. The compression spring 41 provides an upward tendency for the clamping block 4. The clamping block 4 moves upward, thereby fixing the sound-absorbing cotton 321 above. This achieves the simultaneous fixing of the sound-absorbing cotton 321 during the docking installation, further improving efficiency.

[0036] The implementation principle of the theater sound-absorbing ceiling structure and its construction method in this application embodiment is as follows: After the main keel 2 is installed by positioning the vertical suspension rod 1, the secondary keel 31 is installed. The flat side of the C-shaped steel is fixed to the wall. The grooves of the C-shaped steel and the I-beam are opposite each other for installing the splicing plate 32. The sound-absorbing cotton 321 is filled in the cavity of the splicing plate 32 to achieve the sound absorption effect. The splicing plate 32 can slide along the secondary keel 31, and be aligned and spliced ​​one by one. For theaters with a large area, the installation of the sound-absorbing ceiling can be achieved more quickly, and it is more convenient than the traditional structure.

[0037] This application also discloses a construction method for a theater sound-absorbing ceiling structure.

[0038] Referring to all the attached drawings, a construction method for a theater sound-absorbing ceiling structure includes the following steps: S1: Positioning and drilling holes to install vertical hangers 1 and main keel 2; before positioning and drilling, a layer of fiberglass sound-absorbing board 6 can be pasted onto the theater roof. Install the main keel 2 through the vertical hangers 1, ensuring its accurate position, levelness, and ability to withstand the weight of the roof and the influence of the external environment. During installation, appropriate connectors and fixing equipment must be used to ensure the stability and safety of the structure. S2: Install the sound-absorbing structure 3; the sound-absorbing cotton 321 and the abutment plate inside the sound-absorbing structure 3 can be pre-installed and filled into the splicing plate 32 before installation. After installation, the sound-absorbing ceiling needs to be adjusted and improved, including checking whether the installation of the sound-absorbing structure 3 is firm, whether the hanging rod is stable, and whether the sound absorption effect meets the design requirements.

[0039] S3: Sealing and Finishing. Finally, the sound-absorbing ceiling needs to be cleaned and its surface treated, including seam filling and finishing. Plaster powder can be used for seam filling to ensure that the appearance and performance of the sound-absorbing ceiling meet the expected requirements.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
