Description

Technical Field

[0001] This invention relates to the field of ceiling technology where components are located in different planes, and in particular to a safe, convenient, and height-unrestricted theater catwalk system. Background Technology

[0002] To facilitate the installation of lighting, sound, stage machinery and other auxiliary facilities by staff, theaters need to install multiple layers of suspended ceilings in the air. These suspended ceilings are usually called catwalk levels, and some of them are also called specific names such as lighting bridges and sound bridges depending on their function.

[0003] The catwalk level limits the height of performance spaces in a theater. Performances above the catwalk level are difficult for the audience to see and lack the support facilities available there. However, raising the catwalk level is challenging due to structural limitations. Installing high-rise elevators or even stable staircases is difficult. Staff typically use scaffolded catwalk staircases to reach the level – unstable and physically demanding. Some theaters lack even these, requiring the use of ladders or cranes. Because of the difficulty of climbing, the catwalk level is usually set at a height similar to that of a train station ceiling (too high would require performers carrying heavy equipment up unstable and difficult-to-climb scaffolded catwalk staircases, which is impractical).

[0004] Besides the catwalk level, another structural element limiting the height of performance space in a theater is the rectangular stage frame of a proscenium stage. The proscenium stage is the most classic and commonly used stage form. Like a proscenium frame, the performance area faces the audience on one side, with the audience seated directly opposite the stage. This provides an irreplaceable advantage in terms of stage visual integrity and allows performers to focus solely on their viewpoint from the audience. Other stage types, such as extended stages and circular stages, fall short of the proscenium stage in terms of performance effect. Therefore, unless it's a concert or similar performance where visuals aren't the primary focus, the proscenium stage is generally the preferred choice. However, the rectangular stage frame, which acts as the "fourth wall" (a technical term referring to the imaginary "wall" facing the audience in a proscenium stage), is difficult to enlarge because it's typically a truss-column frame. Enlarging it would require consideration of instability due to horizontal loads. Furthermore, the installation of various reinforcing components within the stage is severely limited.

[0005] For most performances, the height restrictions imposed by the catwalk and rectangular platform have little impact on the performance space, as most performances take place solely on the stage surface. However, for certain performance types, this can have serious adverse effects. The most typical example is acrobatics. As is well known, acrobatics involves a large number of aerial maneuvers, many reaching heights of tens of meters or even higher. In these cases, the height restrictions imposed by the catwalk and rectangular platform prevent the performance from proceeding normally, forcing many acrobatic performances to be held in temporary tents or even outdoors. This significantly reduces the performance's effectiveness and safety (due to inadequate performance and safety equipment). Even in top-tier theaters like the National Centre for the Performing Arts, the rectangular platform is only 14 meters high, lower than the requirements for many acrobatic performances. In China, the height of indoor acrobatic stages is generally below 10 meters. The highest, the Water Show International Grand Theatre, reaches 21 meters. However, this was achieved at the expense of stage versatility and performance effect. It is specifically used to perform the large-scale international acrobatic drama "Water Show". The performance equipment is relatively fixed, so there is no need to frequently climb the horse platform, and the horse platform can be made higher. At the same time, its stage form is an extended stage. The performance effect is not as good as the proscenium stage, but it is not limited by the rectangular stage frame.

[0006] The core tube is a component in a steel structure building. It provides the steel structure with stiffness against lateral forces. The core tube has a large length-to-diameter ratio, is inserted in the center of the building and is integrated with the building, and should not exist independently. Summary of the Invention

[0007] This invention provides a safe, convenient, and height-unrestricted theater catwalk system.

[0008] The technical problem to be solved is that the horse track level and rectangular platform frame limit the height of the performance space, which affects the indoor performance of acrobatic shows.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a safe, convenient and height-unrestricted theater catwalk system, used in indoor theaters with proscenium stages and load-bearing enclosures for the installation of performance equipment and the movement of performers. The proscenium stage includes a rectangular stage frame set between the performance area and the audience area, which acts as a "fourth wall". The catwalk system includes multiple catwalk layers suspended below the building. Adjacent catwalk layers are connected vertically by ladders. Except for the top catwalk layer, each catwalk layer has a vertically aligned clearance opening located directly above the performance area. The rectangular stage frame includes a stage frame core tube vertically arranged on the left and right sides of the rectangular stage frame and a stage frame crossbeam horizontally arranged on the top of the rectangular stage frame. Stage waiting rooms are arranged on the left and right sides of the rectangular stage frame. The top of the stage waiting room is a multi-layered steel beam grid aligned vertically. The steel beam grid at the top of the stage waiting room is referred to as the core tube stabilizing grid. The two stage frame core tubes are fixedly connected by the stage frame crossbeam and are respectively fixedly connected to the load-bearing enclosure through the core tube stabilizing grid. The core tube of the platform frame is equipped with a staircase and elevator that connect the upper and lower levels, and the outer wall of the core tube of the platform frame has doors leading to each level of the walkway.

[0010] Furthermore, the core tube stabilizing grid is located below the catwalk layer, and the stage frame beams are multiple reinforced concrete beams aligned vertically. Each reinforced concrete beam corresponds to and is flush with the corresponding catwalk layer. The portion of each catwalk layer located on the outer perimeter of the performance area contains a steel beam grid called a ring grid. The ring grid is fixedly connected to the load-bearing enclosure and forms a ring structure with the flush reinforced concrete beams to stabilize the stage frame core tube. The stage frame core tube is constrained from bottom to top by the floor, the core tube stabilizing grid, and the ring structure composed of the ring grid and reinforced concrete beams.

[0011] Furthermore, the catwalk layers, from bottom to top, are a lighting catwalk layer for installing lighting equipment, an interactive catwalk layer for performers to interact with the audience, a servo catwalk layer for backstage staff to interact with performers, and a top catwalk layer for suspending the lower catwalk layers and serving as the ceiling of the performance area. The lighting catwalk layer consists of two circular catwalks, one located in the center of the audience area and the other located around the perimeter of the performance area. The interactive catwalk layer includes multiple circular catwalks arranged around the center of the building. The circular catwalks of the interactive catwalk layer are concentric circles and have openings for hiding places in the performance area. The circular catwalks are connected by connecting catwalks arranged radially around the center of the concentric circles. One of the circular catwalks that is not blocked by the lighting catwalk layer has a sliding rail at its bottom for suspending performers or performance equipment to move above the audience area. The servo horse track layer includes a ring-shaped horse track located in the center of the audience area and a platform-shaped horse track surrounding the performance area, with the two parts of the horse track connected to form a platform; The top bridle level is a rectangular platform-shaped bridle set directly above the performance area.

[0012] Furthermore, the indoor theater is equipped with a cage-like electromechanical room on the top, which is equipped with ventilation equipment to remove the smoke generated during the performance and the exhaust gas generated by the breathing of people in the building. The top catwalk is located below the electromechanical room and is also used to assist the operation of the electromechanical room. The top catwalk has a steel beam grid that is integrated with the load-bearing enclosure through connecting beams. If there is a beam of the upper level of the catwalk above the hanging column used to suspend the lighting catwalk, interactive catwalk, and servo catwalk, the end of the hanging column is connected to the bottom of the beam of the upper level catwalk; otherwise, it is connected to the top of the building.

[0013] Furthermore, the circular walkway located in the center of the audience area in the illuminated walkway layer is referred to as the cage bottom walkway. Both the interactive walkway layer and the servo walkway layer have circular walkways aligned vertically with the cage bottom walkway. The hanging posts along the edges of the cage bottom walkway and the two circular walkways above it are aligned vertically, and the aligned hanging posts and the three circular walkways they are in together form a multi-level platform with hanging posts as railings. Ladders are provided between each level of the multi-level platform.

[0014] Furthermore, the performance area is equipped with a lift stage, and a stage compartment is located below the performance area. The bottom of the core tube of the stage frame is lower than the bottom of the stage compartment, and a door leading to the stage compartment is opened on the side wall.

[0015] Furthermore, reinforced concrete columns are provided between adjacent reinforced concrete beams to serve as a connection, and the reinforced concrete beams and reinforced concrete columns are combined to form a beam-column grid.

[0016] Furthermore, the indoor theater is a steel structure dome building, and the steel frame of the steel structure dome building is integrated with the steel beam grid at the top of the stage waiting room and the hanging columns used to suspend the catwalk level.

[0017] Furthermore, the stage waiting room is a transparent room with a core tube stabilizing grid at the bottom and steel columns below the edge of the core tube stabilizing grid as the framework, and a concrete slab set at the top and glass panels set around the perimeter as the wall panels. The transparent room is covered with a retractable cover cloth around the perimeter.

[0018] Furthermore, the stage waiting area has doors leading to the performance area, the audience area, the stage frame core, the exterior of the indoor theater, and other buildings adjacent to the indoor theater.

[0019] Compared with existing technologies, the present invention provides a safe, convenient, and height-unrestricted theater catwalk system with the following advantages: In this invention, a rectangular stage frame is formed by a core tube and stage frame beams. Elevators and stairs leading to each catwalk level are installed within the core tube, allowing performers to safely and conveniently move up and down the catwalk levels, eliminating height restrictions. Simultaneously, the steel beam grid at the top of the stage waiting area, the stage frame beams, and specific locations on the catwalk levels support the slender and exposed core tube (in traditional steel core tube structures, the core tube is typically encased by numerous floor slabs, beams, and columns; here, however, it is not, and due to space constraints, its cross-section is even smaller). This not only prevents the core tube from tipping over, but the supporting components themselves can be integrated into the theater (into the stage waiting area, the rectangular stage frame, and the catwalk levels), without affecting the theater's visual appeal or occupying additional space. The combination of these points significantly increases the height of the theater's performance space without sacrificing stage versatility or performance effectiveness. Attached Figure Description

Detailed Implementation

[0021] Taking the China Acrobatic Arts Center, which has applied this invention, as an example, such as... Figure 1-2 As shown, a safe, convenient, and height-unrestricted theater catwalk system is used in indoor theaters with proscenium stages and load-bearing enclosures for the installation of performance equipment and the movement of performers. The proscenium stage includes a rectangular stage frame set between the performance area 1 and the audience area 2, which acts as a "fourth wall". The catwalk system includes multiple catwalks suspended below the building. Adjacent catwalks are connected by ladders. Except for the top catwalk, each catwalk has a vertically aligned clearance opening located directly above the performance area 1. Multiple catwalk levels enclose the performance area 1 and the stage frame core tube 31. Although these catwalk levels are not as stable as the floor slabs in a steel structure core tube building, this arrangement allows for the installation of other load-bearing components within the catwalk levels to support the stage frame core tube 31. These load-bearing components can be integrated with the catwalk levels. Furthermore, the close proximity of the catwalk levels to the performance area 1 allows equipment and performers to access the area very easily.

[0022] The rectangular stage frame includes a stage frame core tube 31 vertically arranged on the left and right sides of the rectangular stage frame and a stage frame crossbeam 32 horizontally arranged on the top of the rectangular stage frame. Stage waiting rooms are arranged on the left and right sides of the rectangular stage frame. The top of the stage waiting room is a multi-layered steel beam grid aligned vertically. The steel beam grid on the top of the stage waiting room is referred to as the core tube stabilizing grid 4. The two stage frame core tubes 31 are fixedly connected through the stage frame crossbeam 32, and are respectively fixedly connected to the load-bearing enclosure through the core tube stabilizing grid 4. The core tube 31 of the platform frame is equipped with a staircase and elevator that connect the upper and lower levels, and the outer wall of the core tube 31 of the platform frame has doors leading to each level of the catwalk.

[0023] The stage frame core tube 31 involved in this invention has a length of more than 30 meters above the theater floor and more than 10 meters below the theater floor, plus a section of more than 40 meters. In terms of shape, it is a thin and long structure similar to a chimney. However, since it needs to house elevators and stairs, its structure is the same as that of a conventional core tube. It cannot maintain stability on its own like a chimney. Therefore, a large number of supporting components are required. The core tube stabilization grid is one of the supporting components. Other components are set in the catwalk layer, the stage frame beam 32, and the floor.

[0024] The core tube stabilizing grid 4 is located below the catwalk level. The stage frame beams 32 are multiple reinforced concrete beams aligned vertically. Each reinforced concrete beam corresponds to and is flush with the corresponding catwalk level. The portion of each catwalk level located on the outer perimeter of the performance area 1 contains a steel beam grid called a ring grid. The ring grid is fixedly connected to the load-bearing enclosure and forms a ring structure with the flush reinforced concrete beams to stabilize the stage frame core tube 31. The stage frame core tube 31 is constrained from bottom to top by the floor, the core tube stabilizing grid 4, and the ring structure composed of the ring grid and reinforced concrete beams.

[0025] These restraining components act like the wall ties of a tower crane, restraining the core tube 31 of the platform frame at regular intervals. The ring-shaped grid here is itself part of the steel beams of the catwalk level, only presented as a grid. Where the ring-shaped grid is close to the main structure of the theater, it can be connected to the main structure using connecting beams, ensuring the stability of the catwalk level even when suspended by hinged columns. In this embodiment, the core tube stabilizing grid 4 is arranged in three layers at intervals. Without the ring-shaped grid, several additional layers of core tube stabilizing grid 4 would need to be set above the core tube stabilizing grid 4 in this embodiment.

[0026] From bottom to top, the catwalk layers are: a lighting catwalk layer 51 for installing lighting equipment, an interactive catwalk layer 52 for performers to interact with the audience, a servo catwalk layer 53 for backstage staff to interact with performers, and a top catwalk layer 54 for suspending the catwalk layers below and serving as the ceiling of performance area 1. Here, the shape and location of the horse runway are used to determine its appropriate function. In actual use, the distinction is not so strict. Various performance equipment are set on different horse runways according to the needs of the performance, and backstage staff and performers are not restricted by the horse runway.

[0027] The lighting catwalk level 51 consists of two circular catwalks, one located in the center of the audience area 2 and the other on the periphery of the performance area 1. This level is the lowest to ensure that the lighting is unobstructed, and different lighting fixtures are installed on the two circular catwalks.

[0028] The interactive catwalk layer 52 includes multiple circular catwalks arranged around the center of the building. The circular catwalks of the interactive catwalk layer 52 are concentric circles and have openings for hiding places in the performance area 1. The circular catwalks are connected by connecting catwalks arranged radially around the center of the concentric circles. One of the circular catwalks that is not blocked by the lighting catwalk layer 51 has a sliding rail 521 at its bottom for suspending performers or performance equipment to move above the audience area 2. Many acrobatic acts require the performer to pass above the audience. These acts are typically performed outdoors using cranes, but here, a sliding rail 521 is used, which is more stable and safer. Besides these acrobatic movements, performance equipment that needs to move during the performance can also be mounted on the sliding rail 521. In this embodiment, one sliding rail 521 is installed. If needed, sliding rails 521 can be installed on multiple circular walkways in the future. In this embodiment, the interactive walkway layer 52 has three circular walkways that are not obstructed by the lighting walkway layer 51 below, and each walkway also has sufficient load-bearing capacity.

[0029] The servo horse track layer 53 includes a circular horse track located in the center of the audience area 2 and a platform-shaped horse track surrounding the performance area 1. The two horse tracks are connected to form a platform. This platform-shaped horse track acts like a command post, allowing the viewer to see the performance area 1 and the various situations on the horse track layers below, and to perform various operations based on the observed situations, or to assist the operations below.

[0030] The top catwalk layer 54 is a rectangular platform catwalk located directly above the performance area 1. Among the three catwalk layers below the top catwalk layer 54, the performance area 1 is surrounded by a ring catwalk, which is sufficient to meet the needs. Here, the top catwalk layer 54 is used to provide attachment points for the hanging columns of the catwalk layers below, because the electromechanical room above the top catwalk layer 54 would block the hanging columns.

[0031] The indoor theater has a cage-like electromechanical room on the top. The electromechanical room is equipped with ventilation equipment to remove the smoke generated during the performance and the exhaust gas generated by the breathing of people in the building. The top catwalk layer 54 is located below the electromechanical room and also assists in the operation of the electromechanical room. The top catwalk layer 54 has a steel beam grid that is integrated with the load-bearing enclosure through connecting beams. If there is a beam of the upper level of the catwalk above the hanging column used to suspend the lighting catwalk level 51, interactive catwalk level 52, and servo catwalk level 53, the end of the hanging column is connected to the bottom of the beam of the upper level catwalk level; otherwise, it is connected to the top of the building.

[0032] The circular walkway located in the center of audience area 2 within the lighting walkway layer 51 is referred to as the cage bottom walkway. Both the interactive walkway layer 52 and the servo walkway layer 53 have circular walkways aligned vertically with the cage bottom walkway. The hanging posts along the edges of the cage bottom walkway and the two circular walkways above it are aligned vertically, and these aligned posts, together with the three circular walkways they occupy, form a multi-level platform with the hanging posts serving as railings. Ladders are provided between each level of the multi-level platform. This area has a large amount of performance equipment and a high volume of personnel movement; therefore, the above structure was designed to further facilitate personnel movement and transfer.

[0033] Performance area 1 is equipped with a lift stage, and a stage compartment is located below performance area 1. The bottom of the stage frame core tube 31 is lower than the bottom of the stage compartment, and the side wall has a door leading to the stage compartment. In other words, the stage frame core tube 31 here is equivalent to a bridge connecting the underground stage compartment, the performance area 1 on the ground, the audience area 2, and the catwalk level in the air.

[0034] Reinforced concrete columns are installed between adjacent reinforced concrete beams to serve as connectors, forming a beam-column grid. The use of reinforced concrete columns here helps to overcome the deflection problem of reinforced concrete beams with large spans.

[0035] The indoor theater is a steel-structured domed building. The steel frame of the domed building is integrated with the steel beam grid at the top of the stage waiting room and the columns used to suspend the catwalk level.

[0036] The stage waiting room is a transparent room with a core tube stabilizing grid 4 at the bottom and steel columns below the edge of the core tube stabilizing grid 4 as the framework, and concrete slabs on the top and glass panels around the perimeter as the walls. The transparent room is covered by a retractable tarpaulin. The stage waiting room allows performers to touch up their makeup, memorize lines, and adjust performance equipment. The transparency allows for observation of the external situation and interaction with the outside when necessary.

[0037] The stage waiting area has doors leading to performance area 1, audience area 2, stage frame core tube 31, the exterior of the indoor theater, and other buildings adjacent to the indoor theater. This opens up more space and connects these spaces to the catwalk level via the stage waiting area, saving time for performers and backstage staff and facilitating the handling of various emergencies such as performers being late or equipment malfunctions.

[0038] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
