Description

Technical Field

[0001] The present invention relates to the technical field of stage equipment.

[0002] In particular, the present invention specifically relates to a stage foundation pit structure with high safety. Background Art

[0003] With the increasing enrichment of cultural life, people have higher and higher requirements for stage effects in performances. In order to make performing arts produce extraordinary special effects, many modern large-scale performance venues have installed various types of stage machinery and equipment, which play the role of adding the finishing touch and genius in the stage performances of the repertoire.

[0004] A stage is typically composed of one or more platforms, some of which can be raised or lowered. It's a major component of a theater building, representing the performance space in front of the auditorium. In ancient open-air theaters, the main stage often extended into the auditorium, either below or above it, allowing the audience to view the play from three sides. Indoor theaters typically have stages facing the auditorium, and there are proscenium stages, extended stages, and center stages. The stage provides a space for actors to perform, allowing the audience to focus on the performance and achieve the desired viewing experience. Therefore, stage safety requirements are very high, especially for temporary stages, which require even higher safety controls. Consequently, the stage base structure must be very strong. Some stages, however, require more than just a base for safety, and require a pit for foundation construction to ensure structural stability.

[0005] The workload of laying the foundation for a conventional stage, or in other words, building a pit, is excessive. However, the safety of ordinary bases for large stages is not guaranteed. For example, Chinese invention patent CN108744553A provides a multifunctional stage base, which relates to the technical field of stage props. This multifunctional stage base includes a base platform, a base chute welded to the bottom of the inner wall of the base platform, a first slider slidably connected to the top of the base chute, a snap-fitting groove formed on one side of the top of the base chute, a first return spring welded to one side of the first slider and the inner wall of the base chute, and the top of the first slider movably connected to a limit rod via a rotating shaft. The multifunctional stage base has a first base block and a second base block welded on both sides of the top of the base, and a background wall on the top of the first base block, so that the stage itself has a background wall, which does not require personnel to carry, thereby speeding up work efficiency. Through the cooperation between the plug holes and the hooks, more backgrounds can be plugged into the background wall, increasing the diversification effect of the stage. However, the stage base is still a simple construction, and its own strength is not high. It is also necessary to set a slide for moving the stage, which greatly reduces the safety of the stage. It will become loose after a long time of use. In addition, the overall space occupied is too large, the base height is too high, and the ground space cannot be effectively utilized. The stage surface height is high, and the installation stability of the stage is not guaranteed.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and safe stage foundation pit structure. Summary of the Invention

[0007] The purpose of the present invention is to provide a stage foundation pit structure that does not require a deep pit to be dug on the ground, but directly digs a bottom pit on the bottom wooden board for fixing, thereby greatly reducing the height of the stage base and the difficulty of installation. The stage board can slide and the stage safety is high.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A highly safe stage foundation pit structure comprises: at least two pit beams arranged parallel to each other, a limiting plate connected to the ends of the pit beams, and a functional block arranged on the pit beams, a through hole arranged in the middle of the functional block for facilitating the passage of the pit beams, a bearing plate arranged above the inner side wall of the through hole, a groove arranged above the functional block, an arc-shaped plate extending upward to the bottom of the groove arranged in the middle of the bearing plate, a downwardly extending annular column arranged in the middle of the arc-shaped plate, a connecting hole arranged on the pit beam, and a reinforcing rib arranged at the connection between the limiting plate and the pit beam.

[0010] The plate body of the stage can slide along the extending direction of the groove of the functional block, and the functional block can slide and displace along the extending direction of the pit beam.

[0011] As a preferred embodiment of the present invention, the angle formed between the limiting plate and the pit beam ranges from 80° to 100°.

[0012] As a preferred embodiment of the present invention, the angle formed between the groove and the pit beam ranges from 80° to 100°.

[0013] That is to say, the pit beam does not touch the ground. In fact, it is the bottom end of the functional block that touches the ground. The pit beam passes through the through hole of the functional block and is supported by the functional block in the air at a certain height from the ground. Then all the pit beams are fixed and limited by the limiting plates. The stage plate is not directly mounted on the pit beam, but is mounted in the groove at the upper end of the functional block. The stage plate can also slide in the groove to adjust its position. After the adjustment is completed, use fixing bolts to pass through the stage plate, and then pass through the annular column of the functional block and drive into the connecting hole of the pit beam. The connecting hole plays the role of a small fixed pit. At this time, the stage plate, functional block and pit beam are all fixed together. At this time, the stage plate cannot slide along the groove of the functional block, and the functional block cannot slide along the extension direction of the pit beam. The stability of the overall structure is higher.

[0014] As a preferred embodiment of the present invention, the limit plate is arranged on the upper side of the end of the pit beam, and the top height of the functional block is not higher than the top height of the limit plate.

[0015] As a preferred embodiment of the present invention, the length of the annular column is not greater than the height of the arc-shaped plate.

[0016] In fact, the curved plate is far away from the pit beam, and the annular column is close to the pit beam, but the length of the annular column is shorter than the height of the curved plate, so the bottom end of the annular column is a certain distance away from the pit beam. This makes it convenient for the fixing screws of the stage plate to pass through the annular column to be limited and inserted into the connecting hole while fixing the fixing bolts. Secondly, it prevents the pit beam from being placed on the ground for a long time, causing dust and soil to enter the connecting hole and making it impossible to insert. The overall structure is more convenient to connect.

[0017] As a preferred embodiment of the present invention, the size of the through hole is equal to the cross-sectional size of the pit beam.

[0018] As a preferred embodiment of the present invention, a notch groove is provided at the bottom of the functional block.

[0019] As a preferred embodiment of the present invention, the connecting hole and the inner side wall of the annular column are both provided with internal threads.

[0020] As a preference of the present invention, the number of the connecting hole is at least one.

[0021] As a preference of the present invention, the number of the limiting plate is at least one.

[0022] As a preference of the present invention, the number of the reinforcing rib is at least one.

[0023] As a preferred embodiment of the present invention, at least a portion of the groove is arc-shaped.

[0024] The high-safety stage foundation pit structure of the present invention has the beneficial effect of: no deep pit is needed in the ground, and a bottom pit is directly dug on the bottom wooden board for fixing, which greatly reduces the height of the stage base and the difficulty of installation, the stage board can slide, and the stage is highly safe.

[0030] The following are specific embodiments of the present invention, which further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of modules and structures set forth in these embodiments do not limit the scope of the present invention.

[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0033] Technologies, methods, and systems known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0034] The workload of laying the foundation of the existing general stage, that is, making the pit, is too large, but the safety of the ordinary base of the large stage is not guaranteed enough. The general stage base is still a simple construction, and its own strength is not high. It also needs to be equipped with a slide for the stage to move. The safety of the stage is greatly reduced, and it will become loose after a long time of use. In addition, the overall space occupied is too large, the base height is too high, and the ground space cannot be effectively utilized. The stage surface height is high, and the installation stability of the stage is not guaranteed.

[0035] Example 1: Figures 1 to 4 The figure shown is only one of the embodiments of the present invention, a stage pit structure with high safety, comprising: at least two pit beams 1 arranged parallel to each other, a limit plate 2 connected to the end of the pit beam 1 and a functional block 3 arranged on the pit beam 1, a through hole 31 is provided in the middle of the functional block 3 to facilitate the passage of the pit beam 1, a bearing plate 32 is provided above the inner wall of the through hole 31, a groove 33 is provided above the functional block 3, an arc-shaped plate 34 extending upward to the bottom of the groove 33 is provided in the middle of the bearing plate 32, a downwardly extending annular column 35 is provided in the middle of the arc-shaped plate 34, a connecting hole 11 is provided on the pit beam 1, and a reinforcing rib 21 is provided at the connection between the limit plate 2 and the pit beam 1.

[0036] In the present invention, multiple pit beams 1 arranged parallel to each other are connected and limited by limiting plates 2, and the structure between the limiting plates 2 and the pit beams 1 is fixed by reinforcing ribs 21. A functional block 3 is provided on each pit beam 1, and the functional block 3 is covered on the outside of the pit beam 1. The size of the through hole 31 is equal to the cross-sectional size of the pit beam 1. The pit beam 1 can just pass through the through hole 31 on the functional block 3 to prevent the functional block 3 from shaking on the pit beam 1. The upper end of the functional block 3 is also provided with a groove 33 for placing the stage board.

[0037] The plate body of the stage can slide along the extending direction of the groove of the functional block, and the functional block can slide and displace along the extending direction of the pit beam.

[0038] Here, the angle formed between the limiting plate 2 and the pit beam 1 ( Figure 4 The angle A) ranges from 80° to 100°, and the angle formed between the groove 33 and the pit beam 1 ( Figure 4 The middle angle B) ranges from 80° to 100°. In fact, the limit plate 2 is arranged perpendicular to the pit beam 1, and the groove 33 extends in the same direction as the limit plate 2, and is also arranged perpendicular to the extension direction of the pit beam 1.

[0039] It should also be noted that the pit beam 1 does not touch the ground. In fact, it is the bottom end of the functional block 3 that touches the ground. The pit beam 1 passes through the through hole 31 of the functional block 3 and is then supported by the functional block 3 in the air at a certain height from the ground. Then all the pit beams 1 are fixed and limited by the limiting plate 2. The stage plate is not directly mounted on the pit beam 1, but is mounted in the groove 33 at the upper end of the functional block 3. The stage plate can also slide and adjust its position in the groove 33. After the adjustment is completed, a fixing bolt is used to pass through the stage plate, and then through the annular column 35 of the functional block 3, and is driven into the connecting hole 11 of the pit beam 1. The connecting hole 11 acts as a small pit. At this time, the stage plate, the functional block 3 and the pit beam 1 are all fixedly connected together. At this time, the stage plate cannot slide along the groove 33 of the functional block 3, and the functional block 3 cannot slide along the extension direction of the pit beam 1. The stability of the overall structure is higher.

[0040] When the stage panel needs to be loosened, it is only necessary to unscrew the fixing bolts. At this time, the stage panel can slide along the groove 33 again, and the functional block 3 can also slide along the extension direction of the pit beam 1.

[0041] In this way, there is no need to dig a pit, and the connecting hole 11 of the pit beam 1 serves as the pit. The height of the stage board from the ground is only the vertical height of the functional block 3, and the height of the stage board from the ground is not very high. The laying of the pit beam 1 and the limit plate 2 is also very convenient, and the overall structural stability is also very high.

[0042] The high-safety stage foundation pit structure of the present invention does not require a deep pit to be dug on the ground. A bottom pit is directly dug on the bottom wooden board for fixation, which greatly reduces the height of the stage base and the difficulty of installation. The stage board can slide and the stage is highly safe.

[0043] Example 2: Still as Figures 1 to 4 The figure shown is only one of the embodiments of the present invention. In this example, it should be noted that the limit plate 2 is arranged on the upper side of the end of the pit beam 1, and the top height of the functional block 3 is not higher than the top height of the limit plate 2. In this way, the limit plate 2 can not only limit the arrangement of the pit beam 1, but also effectively prevent the stage board from crossing the limit plate 2 when sliding, that is, it has a certain limiting effect on the stage board.

[0044] Moreover, the length of the annular column 35 is not greater than the height of the arc-shaped plate 34 .

[0045] In fact, the arc-shaped plate 34 is far away from the pit beam 1, and the annular column 35 is close to the pit beam 1, but the length of the annular column 35 is shorter than the height of the arc-shaped plate 34, so the bottom end of the annular column 35 is a certain distance away from the pit beam 1. In this way, it is convenient for the fixing screws of the stage plate to be limited by the annular column 35 and inserted into the connecting hole 11 while fixing the fixing bolts. Secondly, it is prevented that the pit beam 1 is placed on the ground for a long time, causing dust and soil to enter the connecting hole 11 and making it impossible to insert. The overall structure is more convenient to connect.

[0046] Example 3: Still as Figures 1 to 3 The figure shown is only one of the embodiments of the present invention. In this example, a notch groove 36 is provided at the bottom of the functional block 3. The notch groove 36 has two advantages. The first is that it can reduce the contact area between the bottom of the functional block 3 and the ground, so that the pressure between the functional block 3 and the ground becomes larger, which facilitates the insertion of the lower end of the functional block 3 into the ground soil layer for fixation; the second is that if the top of the notch groove 36 extends to the bottom of the connecting hole 11, then space can be left to facilitate the discharge of the deposited matter in the connecting hole 11 from the bottom when the fixing bolt passes through the connecting hole 11, which facilitates the fixing bolt to pass through the connecting hole 11.

[0047] If necessary, a reinforcement beam can even be added at the notch 36 to ensure the stability of the overall structure.

[0048] Moreover, the connecting hole 11 and the inner side wall of the annular column 35 are both provided with internal threads, which facilitate the screwing in of the fixing bolts of the stage plate for fixing.

[0049] Of course, the number of the connecting holes 11 is at least one. In fact, a plurality of connecting holes 11 are arranged at intervals on the pit beam 1 to facilitate fixing the functional block 3 to the pit beam 1 at multiple positions. Even a plurality of functional blocks 3 can be arranged on one pit beam 1.

[0050] In addition, the number of the limiting plate 2 is at least one. Generally speaking, a limiting plate 2 is connected to both ends of the pit beam 1. The number of the reinforcing ribs 21 is at least one. Multiple reinforcing ribs 21 are provided at the connection between each pit beam 1 and each limiting plate 2 to ensure the connection stability between the pit beam 1 and the limiting plate 2.

[0051] Finally, at least a portion of the groove 33 is arc-shaped, which facilitates the sliding of the stage board.

[0052] The high-safety stage foundation pit structure of the present invention does not require a deep pit to be dug on the ground. A bottom pit is directly dug on the bottom wooden board for fixation, which greatly reduces the height of the stage base and the difficulty of installation. The stage board can slide and the stage is highly safe.

[0053] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content for which protection is sought in the present invention is fully set forth in the claims.
