Description

Technical Field

[0001] The invention relates to the field of architecture, and in particular to a composite membrane structure and a composite membrane for sports stadiums. Background Art

[0002] The composite membrane of the stadium has a light weight, which perfectly solves the huge visual space requirements that cannot be achieved by traditional reinforced concrete, steel structure, etc. At the same time, the composite membrane has good flame retardant and high temperature resistance, and has strong artistic plasticity, which can meet the architect's various special-shaped and simple modeling requirements. In recent years, with the large-scale construction of cable-structured stadiums, composite membrane technology has become increasingly mature. The composite membrane in the prior art only forms a special-shaped surface by attaching to the steel structure and stretching it, and the membrane surface is flat after stretching, which is not suitable for secondary processing. The use of composite membrane as a ceiling in a stadium will reduce the roof load, and can also meet the daily decorative and aesthetic functions of the stadium. At the same time, the stadium will also be used for concerts, cultural performances and other activities during non-game periods. However, the composite membrane of the stadium in the prior art cannot meet the sound insulation requirements, and cultural performances often require the modification of audio and lighting fixtures on the top according to the content of the performance. The composite membrane installed at one time cannot meet the requirements for the modification of the ceiling in cultural performances. For example, Chinese utility model patent CN207597594U discloses a gymnasium based on a combined structure of a hyperstatic ring truss and a cable dome, comprising an outer hyperstatic ring truss structure and a cable dome structure, wherein the outer hyperstatic ring truss structure comprises load-bearing piers, load-bearing columns, struts and truss rods; the cable dome structure comprises an upper chord ridge cable, a lower chord inclined cable, an outer ring beam, an inner ring beam and a compression rod; the outer hyperstatic ring truss structure is consolidated with the ground to provide the necessary restraint force to balance the huge tension generated by the cable dome structure roof, and the cable dome structure forms a self-stressed spatial structural system through the upper chord ridge cable, the lower chord inclined cable and the compression rod; the outer ends of the outer upper chord ridge cable and the lower chord inclined cable in the cable dome structure are fixed on the outer hyperstatic ring truss structure, and the outer ring beam, the inner ring beam and the compression rod in the cable dome structure fix the shape of the overall structure. Another example is a rigid roof combined tension dome structure disclosed in Chinese utility model patent CN206928432U, which includes an external cable truss structure and an internal cable dome structure, wherein the external cable truss structure includes an outer ring, a cable truss ridge cable, a cable truss upper ring cable, a cable truss lower ring cable and a cable truss oblique cable, and the internal cable dome structure includes an inner pull ring and at least one ring component arranged between the inner pull ring and the external cable truss structure. In the above two patents, after the composite membrane is installed on the top of the stadium, the composite membrane is formed once and cannot be installed twice, cannot be soundproofed, and cannot be installed with audio and lighting fixtures twice, thus failing to meet the renovation needs of theatrical performances.

[0003] In view of this, the present invention provides a composite membrane structure and a composite membrane for sports stadiums, which ensure the sound effects and sound insulation functions of theatrical performances by arranging sound-absorbing cotton on the membrane surface, and add loads of stage equipment such as audio equipment and lamps by arranging load-bearing parts and membrane covers, thereby meeting the transformation needs of theatrical performances; at the same time, after the entire composite membrane is installed, the load is directly added through the load-bearing parts, without the need for on-site secondary welding and other operations.

[0019] In this embodiment, the load-bearing rod 4, on the one hand, carries the dividing beam 21, connecting beam 22 and other components below, and on the other hand, provides a storage space for the load-bearing member 71 when it is folded; the setting of the load-bearing member 71 can facilitate the mounting of external loads. When used as a competition venue, the load-bearing member 71 is accommodated in the content space at the lower end of the load-bearing rod 4. When used as a performance venue, the load-bearing member 71 is lowered and extends out of the opening on the membrane body 1. Loads such as audio equipment and lamps are added to the load-bearing member 71 according to performance requirements; the dividing beam 21 and the connecting beam 22 provide a supporting structure for the installation of the membrane body 1 and the sound-absorbing cotton 3.

[0020] Furthermore, a bearing plate 23 is provided on the demarcation beam 21 and the connection beam 22, and an opening is provided on the bearing plate 23, and a steel wire passes through the opening to form a steel mesh, and the sound-absorbing cotton 3 is arranged on the steel mesh. Furthermore, the demarcation beam 21 and the connection beam 22 are aluminum alloy steel pipes with a diameter of 102 mm. Furthermore, the spacing between adjacent openings on the bearing plate 23 is 200 mm, the diameter of the opening is 12 mm, and the diameter of the steel wire is 2 mm. In this embodiment, the bearing plate 23 and the steel mesh are used to install the sound-absorbing cotton 3, so as to effectively fix and install the sound-absorbing cotton 3.

[0021] Furthermore, a membrane cover 6 is provided at the opening of the membrane body 1, and the membrane cover 6 is used to close the opening when the load-bearing member 71 is retracted. Furthermore, the membrane cover 6 is a Velcro. In this embodiment, the provision of the membrane cover 6 can ensure the integrity of the entire membrane surface when the load-bearing member 71 is retracted, and can also ensure the convenience of operation when the load-bearing member 71 is used, that is, when it is lowered and extended.

[0022] Furthermore, the membrane body 1 is a 0.32 mm glass fiber membrane, and the membrane surface is coated with a low-emissivity coating. In this embodiment, the thermal reflectivity of the membrane body 1 is 60%.

[0023] Furthermore, the mounting beam frame also includes a support rod 24, which is arranged at the intersection of the boundary beam 21 and the connecting beam 22. Both ends of the support rod 24 are fixedly connected to the boundary beam 21 and the connecting beam 22 respectively, and the support rod 24 is used to fix and stabilize the boundary beam 21 and the connecting beam 22.

[0024] Furthermore, the sound-absorbing cotton 3 is 50 mm thick and is wrapped with hydrophobic glass cloth. In this embodiment, through the sound-absorbing cotton 3 and the membrane body 1, the noise reduction coefficient of the entire composite membrane can reach 0.9.

The provision of the load-bearing member 71 can ensure that after the entire composite membrane is installed, there is no need for on-site welding operations when performing secondary transformations of cultural performances.

[0026] Embodiment 2: Based on Example 1, Figure 3 , 4 As shown, a double clamping plate 72 is provided at the lower end of the load-bearing rod 4, and the double clamping plate 72 is connected to the load-bearing member 71 by bolts 74 and nuts 75.
