On the basis of meeting the technological level of modern theater stage machinery, it must also meet the increasing use requirements of lighting, sound and other equipment, while ensuring absolute safety and reliability.

[0003] However, theaters and multi-purpose halls now generally use steel structure grid roofs. This steel structure grid roof is composed of large profiles and grid plates. Its load is borne by the roof steel structure and the embedded plates around the grid roof. The main load is the embedded plates around the grid roof. There are only a relatively small number of hanging columns on the grid roof. This makes the main steel structure of the grid roof very large, the installation space is limited, and the audience can easily see the grid roof, which is visually unsightly. In addition, this steel structure grid roof causes great interference to the lighting during the performance, is not conducive to the arrangement of the performance equipment, and reduces the performance effect.

[0094] The present invention provides a method for implementing a shadowless network device, comprising:

[0095] Install the lifting point beam structure on the roof structure beam of the building to lift the electric hoist through the lifting point beam structure;

[0096] Install the grid top conversion structure on the roof structure beam and make it below the hanging point beam structure, so as to support the shadowless structure through the grid top conversion structure;

[0097] A shadowless structure having a wire rope net woven from steel ropes is installed below the grid top conversion structure to carry staff and / or performance equipment through the shadowless structure.

[0098] The shadowless net device formed by the method of the present invention can meet the requirements of increasingly diverse stage performance methods such as celebrations, singing and dancing, drama performances, large-scale activities, etc., and has changed the use limitations of more and more theaters, concert halls, art centers, exhibition halls, etc. Moreover, since the structure of the shadowless net device for carrying staff and performance equipment is a wire rope net woven from multiple steel ropes, the wire rope net will not produce shadows due to stage lights during the performance, which makes it almost invisible to the audience when watching the performance in the entire building, thereby greatly improving the effect of the audience watching the performance.

[0099] The structural diagram of the shadowless network device used in the method of the present invention can be as follows: Figure 1-Figure 3 As shown in Figure 1- Figure 3 It can be known that the shadowless net device of the present invention includes: a hanging point beam structure 1 installed on the roof structure beam 5 of the building, used for hanging an electric hoist (not shown in the figure) through the hanging point beam structure 1; a grid top conversion structure 2 installed on the roof structure beam 5 and located below the hanging point beam structure 1, used for supporting a shadowless structure 3 through the grid top conversion structure 2; a shadowless structure 3 installed below the grid top conversion structure 2 and having a wire rope net woven from steel ropes, used for carrying staff and / or performance equipment through the shadowless structure 3.

[0100] like Figure 4 FIG. 1 is a schematic diagram of installing the suspension beam structure 1 on the roof of a building. Figure 5 , Figure 6 They are Figure 4 AA view and BB view in. Figure 4-Figure 6It can be known that the suspension beam structure 1 of the present invention comprises a plurality of suspension beam cross beams 101 installed on the roof structure beam 5 and a round tube 102 fixedly installed below the suspension beam cross beam 101. The electric hoist is hoisted through the round tube.

[0101] Specifically, a plurality of mutually parallel roof structure beams 5 are arranged on the roof of the building used for performances, and a plurality of mutually parallel suspension point beams and cross beams 101 are installed between adjacent roof structure beams 5, and the extension direction of the suspension point beams and cross beams 101 is perpendicular to the extension direction of the roof structure beams 5. During assembly, the spacing between adjacent suspension point beams and cross beams 101 can be between 1.5 and 2.5 meters.

[0102] When installing the suspension point beam cross beam 101 between adjacent structural beams of the building roof structure beam, it is also necessary to fix a suspension point plate 103 (such as Figure 8-Figure 9 As shown in FIG. 1 , the suspension point plate 103 is fixed on the surface of the roof structure beam 5 facing the corresponding suspension point beam cross beam 101 through multiple screws 104. To ensure the stability of the suspension point plate 103 and the roof structure beam 5 when connected, the two can be further connected by anchoring adhesive and anchor bolts. Then, the two ends of the suspension point beam cross beam 101 are respectively fixedly connected to a pair of suspension point plates 103 on the opposite surfaces of a pair of structural beams, and welding can be used for connection.

[0103] A round tube 102 (such as Figure 7 As shown), the round tube 102 can be fixed below the suspension beam cross beam 101 by welding, and the extension direction of the round tube 102 is perpendicular to the extension direction of the suspension beam cross beam 101, that is, the extension direction of the round tube 102 is consistent with the extension direction of the roof structure beam 5.

[0104] After the shadowless net device is formed, an electric hoist (not shown in the figure) can be hoisted through the round tube 102. The electric hoist is the main tool for installing lamps. When in use, the electric hoist can be hoisted on the round tube near the lamp as needed. Therefore, when designing, it is necessary to ensure that the installation position of these round tubes can meet the installation needs of all lamps on the entire shadowless net device.

[0105] In addition to the above-mentioned suspension point beam structure 1, a grid top conversion structure 2 is also installed on the roof structure beam 5. The grid top conversion structure 2 is located below the suspension point beam structure 1 and is the supporting part of the shadowless structure in the entire shadowless network device.

[0106] like Fig.10 FIG. 2 is a schematic diagram showing the structure of the grid-top conversion structure 2 of the present invention installed on the roof of a building. Fig.11 , Fig.12 They are Fig.10AA view and DD view. Figure 10-12 As shown, the grid top conversion structure 2 includes: a grid top crossbeam installed under the building roof structure beam 5; a hanging column 220 fixedly installed under the grid top crossbeam for hanging the shadowless structure. In addition, it also includes a shackle for installing the hanging rod for installing lighting and sound on the hanging column.

[0107] Specifically, a plurality of mutually parallel top cross beams are installed below the roof structure beam 5 of the building, such as a pair of first top cross beams 203 located at both ends of the roof structure beam 5 and a plurality of second top cross beams 204 located between the pair of first top cross beams 203. The length extension direction of each top cross beam is perpendicular to the length extension direction of the roof structure beam 5, and the upper portion of the second top cross beam 2034 is fixedly connected to the lower portion of each roof structure beam 5 at the same time. Since stairs are provided on both sides of the roof of the building above the performance stage (i.e., at the positions below the two ends of the outermost roof structure beam 5), the upper portion of the first top cross beam 203 is fixedly connected to the lower portions of the other roof structure beams at the same time, except for not being connected to the lower portions of the pair of roof structure beams 5 close to the outermost edges, that is, one end of the first top cross beam 203 is cantilevered outside the roof structure beam.

[0108] Since the span of the fence top beam is large (i.e. the fence top beam is very long), it is usually assembled on site in a splicing mode. Figure 16-18 As shown, two sections of the top crossbeams are butt-jointed together by two splicing steel plates 209 , and the splicing steel plates are connected to the top crossbeams by bolts 205 , nuts 206 and washers 207 .

[0109] When connecting each fence top crossbeam to the bottom of the roof structure beam 5, the two need to be connected together through a clamp. Due to different installation positions, the structure of the clamp is slightly different, but they are all connecting parts connected to the civil structure (i.e., the roof structure beam 5) and the fence top crossbeam.

[0110] The clamp may be a common clamp, comprising: a second steel plate connected to the side of the roof structure beam; a pair of third steel plates parallel to each other and used to clamp and fix the top cross beam of the fence, the third steel plate located on the top is fixedly connected to the bottom of the second steel plate, and the third steel plate is arranged vertically to the second steel plate. Furthermore, the clamp also includes at least one first steel plate perpendicular to both the second steel plate and the third steel plate located on the top.

[0111] Alternatively, the clamp can also be a reinforced clamp, including: a second steel plate connected to the side of the roof structure beam; a pair of third steel plates parallel to each other and used to clamp and fix the top crossbeam of the grid, the third steel plate located at the top is fixedly connected to the bottom of the second steel plate; a reinforcing rib plate fixedly installed on the upper surface of the third steel plate located at the top and connected to the bottom of the second steel plate.

[0112] Specifically, when one end of the second top cross beam 204 adjacent to the first top cross beam 203 is connected to the outer side of the roof structure beam 5, the following method can be used: Fig.10 , Figure 29-Figure 32b The first clamp 201 shown in the figure is a common clamp, comprising: a pair of first steel plates I 2011, a second steel plate I 2012, and a pair of third steel plates I 2013 parallel to each other, wherein the first steel plate I is a rib plate in a right-angle trapezoidal shape (such as Fig.32a As shown), the second steel plate I is a rectangular steel plate, and the third steel plate I is also a rectangular steel plate (as shown Figure 32b As shown in FIG. 1 , during installation, the first steel plate I and the second steel plate I are arranged vertically, and a pair of first steel plates I are parallel and fixedly installed on the second steel plate I at right angles. The steel plate located at the top of a pair of third steel plates I is respectively perpendicular to the first steel plate I and the second steel plate I and fixedly connected to the bottom ends of these steel plates. The pair of first steel plates I can increase the connection strength between the third steel plate I and the second steel plate I. During connection, each steel plate can be connected together by welding, the second steel plate I is fixedly installed on the side of the roof structure beam 5, the second grid top beam 204 is arranged between the pair of third steel plates I, and the two sides of the pair of third steel plates I are connected by multiple bolts I2014 to clamp and fix the second grid top beam 204 (correspondingly, the spacing between the bolt holes set on the pair of third steel plates I is greater than the corresponding size of the grid top beam, and each grid top beam is connected to the clamp in this way). The second grid top beam 204 can be an I-shaped beam, and each grid top beam can adopt the same structure. When the second steel plate I is fixedly installed on the roof structural beam 5, multiple anchor bolts 2000 can be used to anchor the second steel plate I on the roof structural beam 5. For example, HIT-RE 500 anchoring adhesive and HAS-E screws (size M24) are used as anchor bolts to anchor the second steel plate I on the roof structural beam 5, so that the second steel plate I is firmly fixed on the roof structural beam (the connection between each clamp and the roof structural beam 5 can be made in the same way, see Figure 13-Figure 18 ).

[0113] When the first grid top cross beam 203 is connected to the roof structure beam 5 located in the middle of the roof, the method shown in FIG. 10 and FIG. Figure 32-Figure 35The second clamp 202 shown is an ordinary clamp, which also includes three steel plates, namely, two pairs of first steel plates II 2021, a pair of second steel plates II 2022, and a pair of third steel plates II 2023. The three steel plates are connected in the same way as the three steel plates of the first clamp. The difference is that the second steel plate II 2022 of the second clamp 202 is a trapezoidal steel plate, that is, the width of the upper bottom edge of the second steel plate II is greater than the width of the corresponding roof structure beam, and both sides of the second steel plate II are exposed to the roof structure beam. The part exposed to the roof structure beam is similar to the first clamp. Correspondingly, the length of the third steel plate II 2023 is longer, so that the lower bottom edge of the second steel plate II can be vertically welded to the third steel plate II 2023. The two pairs of first steel plates II 2021 and the pair of second steel plates II 2022 are respectively located on both sides of the roof structure beam 5. Similarly, a pair of third steel plates II 2023 are connected and clamped to fix the first grid top cross beam 203 by multiple bolts II 2024, and the second steel plate II can be anchored to the side of the roof structure beam 5 by multiple anchor bolts 2000. When making the second clamp, the first steel plate II 2021 and the second steel plate II 2022 are welded together in the factory, and then the third steel plate II 2023 with a connection relationship is welded at the installation site, so as to prevent the problem of being unable to install due to too large errors in the civil engineering structure (this connection method can be used for the connection of the third steel plates of each clamp).

[0114] When the end of the first grid top cross beam 203 located on the inner side of the roof is connected to the roof structure beam 5 located on the inner side of the roof, the following method can be used: Fig.10 , Figure 36-Figure 38 The third clamp 210 shown has the same structure as the first clamp and also includes three steel plates, namely, a pair of first steel plates III2101, a second steel plate III2102, and a pair of third steel plates III2103, and the third steel plate III2103 is connected to the first grid top beam 203 by a plurality of bolts III2104. The specific structure of the third clamp can be referred to the structure of the first clamp and will not be described in detail here.

[0115] When the portion of the second top cross beam 204 adjacent to the first top cross beam 203 except the two ends is connected to the corresponding portion of the roof structure beam 5, if the lower portion of the second top cross beam 204 is not provided with a hanging column 220, the second top cross beam 204 can be connected to the roof structure beam 5 by using the structure of the second clamp; and when the lower portion of the second top cross beam 204 is provided with a hanging column 220, the structure of the second clamp can be used as follows: Figure 11-Figure 15 , Figure 39-41The fourth clamp 211 shown has a structure that is basically the same as that of the second clamp 202, except that a larger number of bolts are used between a pair of third steel plates of the fourth clamp, and the second grid top beam 204 is located between a pair of bolts located in the middle of multiple pairs of bolts connecting a pair of third steel plates, and the lower part of the bolt not only passes through the third steel plate located below, but also passes through the connecting plate of the suspension column, thereby connecting a pair of third steel suspension columns together through bolts, and clamping and fixing the second grid top beam 204.

[0116] During construction, the connection between one or more second grid top cross beams 204 and the roof structure beam 5 can be reinforced by using a reinforcing fixture as needed, for example, Fig.10 As shown, the following reinforcing clamps are used to connect the second second grid top cross beam 204 close to the first grid top cross beam 203 and the roof structure beam 5 (see each clamp for details). Figure 42-Figure 53 ): a fifth clamp 214 connecting the inner end of the second grid top beam 204 to the innermost roof structural beam 5 of the roof, a sixth clamp 215 connecting the outer end of the second grid top beam 204 to the outermost roof structural beam 5 of the roof, a seventh clamp 216 connecting the middle part of the second grid top beam 204 to the middle roof structural beam 5, and an eighth clamp 217 connecting the part of the second grid top beam 204 between the end and the middle part to the corresponding roof structural beam 5.

[0117] Among them, Figure 42-Figure 44 As shown, the structure of the fifth clamp 214 adopted in the present invention is based on the structure of the first clamp 201, and further adds a reinforcing rib plate 2148 arranged side by side with the second steel plate on the third steel plate. During manufacturing, compared with the first clamp 201, the width of the third steel plate in the fifth clamp is wider than the width of the third steel plate in the first clamp, and a reinforcing rib plate 2148 adjacent to the second steel plate is welded on the third steel plate. The thickness of the reinforcing rib plate 2148 is the same as that of the second steel plate, and it is spliced ​​as a whole with the bottom of the second steel plate, so that the two side surfaces of the reinforcing rib plate and the two side surfaces of the second steel plate are respectively located in the same plane. In addition, the width of the third steel plate located at the bottom of a pair of third steel plates in the fifth clamp, that is, steel plate 2145, is smaller than the width of the third steel plate located at the top (see Fig.43 ), and among the bolts used to connect the upper and lower third steel plates, at least one is located on the portion of the third steel plate used for welding the reinforcing rib plate 2148.

[0118] like Figure 45-Figure 47As shown, the structure of the sixth clamp 215 used in the present invention is basically the same as that of the fifth clamp 214, except that, since the sixth clamp 215 and the fifth clamp 214 are connected to the outer roof structure beam 5 and the inner roof structure beam 5 respectively, the arrangement position of the reinforcing rib plate of the sixth clamp 215 and the reinforcing rib plate of the fifth clamp 215 on the third steel plate is just opposite (see Fig.43 , Fig.46 ), except for this, the structure of the sixth clamp is basically the same, and the structure of the sixth clamp is not described in detail here.

[0119] If a suspension column 220 is provided at the lower part of the second grid top crossbeam 204, the following method can be used: Figure 48-Figure 50 The reinforcing clamp shown is the seventh clamp 216 used in the present invention. As can be seen from the figure, the structure of the seventh clamp is based on the fourth clamp, and a pair of reinforcing ribs 2168 are added, which are arranged side by side with a pair of second steel plates on the third steel plate located above (i.e., they are located on both sides of the roof structure beam respectively). The arrangement of the reinforcing ribs is basically similar to that of the reinforcing ribs in the fifth clamp, and will not be described in detail here. Similarly, the width of the third steel plate located below, i.e., steel plate 2167, is smaller than the width of the third steel plate located above, and one end of the third steel plate below is flush with one end of the third steel plate located above for welding the reinforcing ribs.

[0120] If the lower part of the second grid top crossbeam 204 is not provided with a hanging column 220, the following method can be used: Figure 51-Figure 53 The reinforcing clamp shown is the eighth clamp 217 used in the present invention. As can be seen from the figure, the structure of the eighth clamp 217 is basically the same as the structure of the seventh clamp, the difference is that the number of bolts used in the eighth clamp is less than the number of bolts used in the seventh clamp.

[0121] Among them, the hanging column 220 fixedly installed below the corresponding grid top cross beam is a column suspended downward from the grid top cross beam in the vertical direction, which is used to hang the shadowless structure on the column. During installation, each grid top cross beam is first installed below each roof structure beam of the building, and then two to three grid steel structure dimensions are designed according to the structural shape of the shadowless structure to be installed, the position of the hanging column is set, and then the hanging column is fixed below the corresponding grid top cross beam. Because the grid top cross beam and the hanging column are responsible for the load of the entire shadowless structure, the strength of the grid top cross beam and each hanging column must be professionally calculated to ensure overall safety. At the same time, the hanging column is an installation column for installing the hanger rod for lighting and sound, and a professional shackle is used to install the hanger rod and the hanging column, and the shackle can adopt the shackle of the prior art.

[0122] The present invention installs a shadowless structure below the grid top conversion structure, which includes: a grid steel structure installed below the grid top conversion structure, used as the main supporting frame of the shadowless structure; a wire rope frame installed on the grid steel structure, on which a wire rope net woven from steel ropes is installed.

[0123] Among them, Figure 19-21 As shown, the grid steel structure includes a plurality of suspension rods correspondingly connected to the suspension columns in the grid top conversion structure and a plurality of frame beams installed around the bottom of the suspension rods and staggered horizontally and vertically to form a grid-shaped frame.

[0124] The plurality of frame beams include a plurality of frame cross beams extending transversely along the roof and a plurality of frame longitudinal beams extending longitudinally along the roof. The plurality of frame cross beams include: Fig.19 The multiple first beams 302 (10 beams are shown in the figure, and are arranged in parallel along the longitudinal direction), the multiple second beams 303 (10 beams are shown in the figure, and are arranged in parallel along the longitudinal direction), and the multiple third beams 304 (30 beams are shown in the figure, and each group of 10 beams is arranged in parallel along the longitudinal direction) are arranged in parallel. The first beams 302, the second beams 303 and the corresponding third beams 304 can be connected end to end in the transverse direction of the roof. The multiple groups of frame longitudinal beams include multiple first longitudinal beams 301 (12 beams are shown in the figure, and each group of 6 longitudinal beams is arranged in parallel along the transverse direction, and two groups of first longitudinal beams are arranged on both sides of the longitudinal direction of the roof), and multiple second longitudinal beams 305 (42 beams are shown in the figure, and each group of 6 longitudinal beams is arranged in parallel along the transverse direction). The first longitudinal beams and the corresponding multiple second longitudinal beams are connected end to end in the longitudinal direction. Each crossbeam and longitudinal beam is installed around each hanger, that is, each hanger can be installed with frame crossbeams and frame longitudinal beams in four directions of up, down, left and right, so as to form a large frame of the wire rope net plane, which is the main supporting frame of the wire rope net.

[0125] During design, the suspenders and booms shall be arranged as required, such as Figure 19-21As shown, hangers can be set at the intersections of the longitudinal beams and the corresponding cross beams, such as hangers 320 and hangers 306 at the intersections of the first longitudinal beam 301, the second longitudinal beam 305 and the corresponding first cross beam 302, hangers 321 at the intersections of the first longitudinal beam 301 and / or the second longitudinal beam 305 and the corresponding first cross beam 302, the second cross beam 303, hangers 321, hangers 320, hangers 308 at the intersections of the first longitudinal beam 301 and / or the second longitudinal beam 305 and the corresponding second cross beam 303, the third cross beam 304, hangers 320, hangers 319, hangers 307, hangers 316 and hangers 317 at the intersections of the first longitudinal beam 301 and / or the second longitudinal beam 305 and the corresponding third cross beam 304. In addition, steel pipes, such as steel pipe 311, steel pipe 310, and steel pipe 309, can be placed between adjacent hangers as needed. The length extension direction of each steel pipe is consistent with the extension direction of the beam and is located above the corresponding beam. When connecting, the two ends of the steel pipe can be hung on the corresponding hanger through the aluminum alloy hook 312, so that installation and disassembly are convenient and quick.

[0126] During assembly, the connection methods of the longitudinal beams and cross beams at different positions are slightly different. For example, the connection between the first longitudinal beam and the first cross beam at the corner of the grid steel structure can be Fig. 22 The connection method shown in FIG. 1 is that a suspension rod 306 is fixedly connected to a first longitudinal beam and a first cross beam by bolts 313, nuts 314 and washers 315 (see FIG. 1 ). Fig.24 ) Fix the first horizontal beam and the first longitudinal beam at an angle of 90 degrees to the outer periphery of the hanger.

[0127] When the first longitudinal beam is connected with the second cross beam and the third cross beam in a T-shape, Fig.23 As shown, by bolts 313, nuts 314 and washers 315 (see Fig.24 ) are fixed to the outer periphery of the suspension rod. When the first longitudinal beam and / or the second longitudinal beam are connected to the second transverse beam and / or the third transverse beam in a cross shape, such as Fig.24 As shown, each beam is also fixed to the outer periphery of the corresponding suspension rod by bolts 313, nuts 314 and washers 315.

[0128] By arranging more cross beams and longitudinal beams at positions close to the outer roof structure beams, that is, the length of the first cross beam is smaller than the size of the second cross beam, and the length of the second cross beam is smaller than the length of the third cross beam, the spacing between adjacent longitudinal beams located on the outside is smaller than the spacing between other adjacent longitudinal beams, thereby ensuring the firmness of the lifting equipment and the safety of the operators working on the wire rope net.

[0129] When the hanger is connected to each beam, a mounting plate with holes (such as Fig.25 As shown, there are four holes respectively), and the hanger rod and the corresponding beam are connected together by means of bolts passing through the screw holes of the two mounting plates.

[0130] After the grid steel structure is formed, a wire rope frame is installed on each grid formed by the grid steel structure, so that a wire rope net woven by steel ropes is installed on the wire rope frame.

[0131] like Fig.26 As shown, the wire rope frame is a frame made according to the grid size of the above-mentioned grid steel structure. Installation holes are punched on the frame at a preset interval (such as 60 mm). The purpose of these installation holes is to install the wire ropes. During installation, these frames are first installed on the corresponding crossbeams of the grid steel structure (which can be connected through the above-mentioned connecting plates). After the frames are installed, a wire rope with an outer diameter of less than 10 mm (such as 6 mm) is passed horizontally through the installation holes on each frame. After the horizontal wire rope is installed, the wire rope extending in the longitudinal direction is installed. During the installation, the wire ropes are interlaced with the horizontal wire ropes to form an integrated wire rope net, as shown in FIG. Fig.26 As shown, a complete wire rope net structure (i.e., a shadowless structure) can be assembled by wire rope nets 601, 602, 603, 604, 605, 606, 623, 624, etc. distributed at the edges, corners and middle positions of the entire grid steel structure and corresponding frames.

[0132] In addition, wire rope tensioning devices are installed on all the steel ropes on the lateral and longitudinal outer sides of the entire wire rope net, which are used to tension the corresponding steel ropes during installation and use. When installing the steel rope, the steel rope is installed by means of rings, lock spiral buckles, joints, etc., and these components can adopt the international standard parts used when installing the steel rope. In order to prevent the steel rope from being damaged due to friction between the steel rope and the frame structure, a nylon sleeve 610 as shown in Figure 27 can be put on the outside of the steel rope, and the nylon sleeve 610 is fixed to the corresponding frame by bolts 607, nuts 608, and gaskets 609. In addition, pedals, cover plates, etc. can also be set on the steel rope frame. For example, in order to accommodate a large number of staff or to facilitate the installation of heavy objects, the following can be installed: Fig.26 The first pedal 611 and the second pedal 612 shown are placed on the wire rope frame, and then people, heavy objects, etc. can be installed on the pedals, which is safer and will not damage the wire rope net. The pedal can adopt a frame structure, and a wire mesh is set on the frame. The position of the pedal on the wire rope frame can be moved according to actual use needs. When the wire rope is installed on the wire rope frame, there will be a locking screw buckle at the installation starting end of the wire rope, which will make the area unsuitable for workers to walk. In order to solve this problem, the present invention provides one or more cover plates connected to the corresponding frame by bolts at the corresponding area of ​​the locking screw buckle. For example, it can be as follows Fig.28As shown, the first cover plate 613, the second cover plate 614, and the third cover plate 615 are respectively arranged at the corners of the wire rope frame, and the area where the lock screw buckle is installed is covered by the three cover plates. When the cover plates are arranged, the cover plates are usually arranged around the entire shadowless structure.

[0133] The following describes a method for implementing the shadowless network device of the present invention, which includes the following steps:

[0134] S01. Install the lifting point beam structure on the roof structure beam of the building to lift the electric hoist through the lifting point beam structure;

[0135] Installing the hanging point beam structure on the roof structure beam of the building includes:

[0136] Installing hanging point beam cross beams between adjacent structural beams of the building roof structure beams;

[0137] The round tube is fixedly installed under the crossbeam of the hanging point beam;

[0138] Among them, the electric hoist is hoisted through a round pipe.

[0139] Among them, installing the suspension beam crossbeam between adjacent structural beams of the building roof structural beam includes:

[0140] A hanging point plate is respectively fixedly installed on opposite surfaces of a pair of adjacent roof structure beams;

[0141] The two ends of the crossbeam of the suspension point beam are respectively fixedly connected to a pair of suspension point plates.

[0142] Wherein, the steel wire rope has a diameter of 5-8 mm, and preferably, the diameter of the steel wire rope is 6 mm.

[0143] The hanging point beam structure is the uppermost part of the entire shadowless net equipment. When installing the hanging point beam structure on the roof structural beam of a building, first install the hanging point beam cross beam between adjacent structural beams of the roof structural beam of the building, and then fix the round tube under the hanging point beam cross beam.

[0144] The round tubes of this device are used to install electric hoists, which are the main tools for installing lamps. When in use, the electric hoists can be hoisted on the round tubes near the lamps as needed. The installation positions of these round tubes can ensure the installation of all lamps in the entire shadowless net equipment.

[0145] S02, installing the grid top conversion structure on the roof structure beam and making it below the suspension point beam structure, so as to support the shadowless structure through the grid top conversion structure;

[0146] Installing the grid roof conversion structure on the roof structure beam and below the hanging point beam structure includes:

[0147] Install the top crossbeam of the fence below the structural beams of the building's roof;

[0148] The hanging column used for hanging the shadowless structure is fixedly installed under the crossbeam of the fence top.

[0149] After the hanging column for hoisting the shadowless structure is fixedly installed under the crossbeam on the top of the fence, the hanging rod for installing the lighting and sound is installed on the hanging column through the shackle.

[0150] Specifically, a plurality of mutually parallel top cross beams are installed under the roof structure beams of the building, such as a pair of first top cross beams located at both ends of the roof structure beams and a plurality of second top cross beams located between the pair of first top cross beams, the length extension direction of each top cross beam is perpendicular to the length extension direction of the roof structure beams, and the upper part of the second top cross beams is fixedly connected to the lower part of each roof structure beam at the same time. Since stairs are provided on both sides of the roof of the building above the performance stage (i.e., at positions below the two ends of the outermost roof structure beams), the upper part of the first top cross beam is fixedly connected to the lower parts of all other roof structure beams at the same time except for not being connected to the lower parts of the pair of roof structure beams close to the outermost edges, that is, one end of the first top cross beam is cantilevered outside the roof structure beam.

[0151] Since the span of the top crossbeam is large (i.e. the top crossbeam is very long), it is usually assembled on site by splicing. During the assembly, two splicing steel plates are used to butt the two sections of the top crossbeam together, and the splicing steel plates are connected to the top crossbeam by bolts, nuts and washers. When connecting each top crossbeam to the bottom of the roof structure beam, the two are connected together by the above-mentioned clamp.

[0152] Wherein, a hanging column is arranged at the lower part of the top cross beam according to the need, and the hanging column is a column suspended downward from the top cross beam in the vertical direction, and is used to hang the shadowless structure on the column. When a hanging column is arranged under the top cross beam, the connection between the top cross beam and the roof structure beam adopts a reinforcing clamp with a reinforcing rib plate.

[0153] During installation, first install each grid top beam under each roof structure beam of the building, then design two or three grid steel structure dimensions according to the structural shape of the shadowless structure to be installed, set the position of the hanging column, and then fix the hanging column under the corresponding grid top beam. Because the grid top beam and hanging column are responsible for the load of the entire shadowless structure, the strength of the grid top beam and each hanging column must be professionally calculated to ensure overall safety. At the same time, the hanging column is the installation column of the hanger rod for installing lighting and sound. The hanger rod and the hanging column are installed with professional shackles, and the shackles can adopt the shackles of existing technology.

[0154] S03. Install a shadowless structure having a wire rope net woven from steel ropes below the grid top conversion structure to carry staff and / or performance equipment through the shadowless structure.

[0155] Installing a shadowless structure with a wire rope net woven from steel ropes below the grid top conversion structure includes:

[0156] The grid steel structure is installed below the grid top conversion structure to serve as the main support frame of the shadowless structure;

[0157] A steel wire rope frame on which a steel wire rope net woven from steel wire ropes is mounted is installed on the grid steel structure.

[0158] Among them, installing the grid steel structure below the grid top conversion structure includes:

[0159] A suspension rod is installed under the multiple suspension columns of the grid top conversion structure through a shackle, and then a plurality of frame beams extending in the horizontal direction are installed under the suspension rod;

[0160] The plurality of frame beams include frame cross beams extending along the transverse direction of the roof and frame longitudinal beams extending along the longitudinal direction;

[0161] A plurality of frame cross beams and frame longitudinal beams installed between adjacent suspension columns form a plurality of grids staggered in the longitudinal and transverse directions, and the grids are used to install the wire rope frame.

[0162] The process of installing a steel wire rope frame having a steel wire rope net woven from steel wire ropes installed thereon on a grid steel structure comprises:

[0163] Make the wire rope frame according to the grid size;

[0164] A plurality of mounting holes are provided on the wire rope frame at a preset interval (e.g., 6 mm);

[0165] Installing a plurality of steel wire rope frames with a plurality of mounting holes on a plurality of grids of the grid steel structure respectively;

[0166] The steel wire ropes are passed through multiple mounting holes on the steel wire rope frame to form a criss-cross steel wire rope net.

[0167] When threading the wire rope, first thread it horizontally, then thread it longitudinally, and interweave the horizontal and longitudinal threads. After threading, tighten the wire rope through the tensioning device. After the entire shadowless net equipment is installed, make a few lengths of light poles. When in use, install the light poles on the hanging column with a shackle, and then install the lights or audio equipment on the light poles.

[0168] The shadowless net device of the present invention can meet the requirements of increasingly diverse stage performances such as celebrations, singing and dancing, drama performances, and large-scale events, and has changed the limitations of use of more and more theaters, concert halls, art centers, and exhibition halls. The shadowless net device of the present invention is all supported by hanging columns, which are connected to the roof structure beams by hanging columns, so that the grid steel structure that carries the wire rope net can adopt a small-sized steel structure to avoid the audience's gang and lighting problems. In addition, the grid plate is laid between the large steel structures on the top of the steel structure grid. This grid plate is an orthogonal combination of the bearing flat steel and the cross bar according to a certain spacing, and the height of the flat steel is usually 30-40 mm. The wire rope net of the present invention is woven from a few millimeters (such as 6 mm) of steel wire rope, and the height difference is very large. After the light passes through a few millimeters of steel wire rope, it can be completely without any shadow in the theater, and this effect is completely unattainable by the steel structure grid plate. It is precisely because of this that the light from the shadowless wire rope net can reach a greater possibility during the performance. Compared with the prior art, the lights installed on the top of the steel structure grid are only subject to interference from fixed positions and large steel structures, which greatly affects the lighting effect. The shadowless structure of the present invention perfectly solves this problem. It allows the lighting and sound equipment to be installed in almost any position, so that the lights are not interfered by any structure, achieving a more perfect performance effect.

[0169] In summary, the shadowless network device and implementation method of the present invention have the following outstanding advantages:

[0170] 1. The shadowless net device realized by the method of the present invention can meet the requirements of increasingly diverse stage performances such as celebrations, singing and dancing, drama performances, large-scale activities, etc., and has changed the use limitations of more and more theaters, concert halls, art centers, exhibition halls, etc., and the shadowless net device will not produce shadows due to stage lights, so that the audience can hardly see the wire rope net when watching the performance in the entire building, thereby improving the viewing effect.

[0171] 2. The shadowless network equipment and method of the present invention have no size requirements for the installation space of the shadowless network equipment: it can be installed in theaters, multi-purpose halls, concert halls, and conference rooms; it can be installed above the auditorium and above the performance; the size of the installation space is not limited, and it can be installed in both a smaller multi-purpose hall and a larger theater.

[0172] 3. The shadowless net equipment and method of the present invention has a steel wire net that is strong enough to carry a load of up to 200 kilograms per square meter. It can carry audio and lighting equipment without any pressure, and can also carry several workers for normal installation and maintenance. There is no need to set up fixed positions for personnel, and they can move freely throughout the entire steel wire net.

[0173] 4. With the shadowless net equipment and method of the present invention, all lamp poles can be installed on the hanging columns that support the wire rope net, which provides a lot of installation possibilities for lighting and sound equipment. Users can flexibly arrange various lighting and sound equipment on the entire wire rope net according to different requirements of the performance, which greatly improves the effect of the performance.

[0174] 5. The shadowless net device and method of the present invention can install electric hoists with larger loads on the suspension beam structure, and these electric hoists can be more conveniently used in the installation process of lighting and sound equipment.

[0175] Although the present invention has been described in detail above, the present invention is not limited thereto. Those skilled in the art may make modifications based on the principles of the present invention. Therefore, all modifications made based on the principles of the present invention should be understood to fall within the protection scope of the present invention.
