These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0027] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0028] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5 The present embodiment provides a large metal mesh ceiling system, including a steel frame base 1, a conversion layer 2, a metal plate layer 3 and a metal mesh layer 4, the steel frame base 1 is rectangular, the conversion layer 2 is fixedly arranged at the bottom of the steel frame base 1, the metal plate layer 3 is arranged below the conversion layer 2, the metal plate layer 3 is fixedly connected to the conversion layer 2 through a first connection component 5, the metal mesh layer 4 is arranged below the metal plate layer 3, the metal mesh layer 4 is fixedly connected to the conversion layer 2 through a second connection component 6, the metal mesh layer 4 includes an arc-shaped rib 401 and a metal mesh 4 02, the arc-shaped rib 401 and the metal mesh 402 are both arranged along the length direction of the steel frame base 1, the arc-shaped rib 401 has a downward curvature, the metal mesh 402 is connected to the arc-shaped rib 401 by a connecting rope 405, the metal mesh 402 is arranged along the lower surface of the arc-shaped rib 401, and the front and rear ends of the metal mesh 402 are both provided with adjustment components 8, the metal mesh 402 is connected to the steel frame base 1 through the adjustment component 8, and the adjustment component 8 can adjust the distance between the end of the metal mesh 402 and the upper surface of the steel frame base 1.

[0030] The metal mesh 402 is arranged along the lower surface of the arc-shaped rib 401 , which can not only maintain the shape of the large metal mesh when the ceiling is suspended, but also stably fix the metal mesh on the steel frame base 1 . Because the length of the metal mesh in the large metal mesh ceiling is greater than or equal to twenty meters, the metal mesh needs thousands of connecting ropes to be connected to the arc-shaped rib 401. When the metal mesh 402 is suspended, the metal mesh 402 will generate an upward force on the arc-shaped rib 401, and the front and rear ends of the metal mesh will also generate a downward force on the steel frame base. If the tightening force of the metal mesh 402 is too large, the metal mesh will break or the steel frame base will deform. If the tightening force of the metal mesh 402 is too small, the shape of the metal mesh when the ceiling is suspended will be non-uniform. Adjustment components are provided at both ends of the metal mesh 402 to adjust the distance between the end of the metal mesh 402 and the steel frame base 1 when the metal mesh ceiling is suspended, so that the metal mesh 402 generates a suitable tightening force. When the metal mesh 402 is deformed due to its own weight, the metal mesh can be adjusted from both ends of the metal mesh 402, so that the deformed metal mesh can still be arranged along the lower surface of the arc-shaped rib 401 to maintain the shape of the large metal mesh ceiling for a long time.

[0031] A plurality of second connection holes 404 are provided on the arc rib 401. The connection rope 405 passes through the second connection holes 404 and the metal mesh 402 to suspend the metal mesh 402 on the lower surface of the arc rib 401. In this embodiment, the second connection hole 404 is a waist-shaped hole provided in the length direction of the steel frame base 1, and the length of the waist-shaped hole is 20 mm. By providing the waist-shaped hole on the arc rib 401, the connection rope 405 can move left and right when connected to the metal mesh 402, so that when the adjustment components at both ends of the metal mesh 402 are working, the metal mesh 402 can move left and right, reducing the tension generated by the metal mesh 402 when adjusting, and improving the safety when adjusting the metal mesh. In order to ensure the carrying capacity of the connection rope 405, the connection rope 405 in this embodiment is a steel wire rope.

When the open end of the first hoop member 601 is inserted into the second hoop member 602, the fastener passes through the first hoop member 601 and the second hoop member 602. The through hole on the groove wall of the second hoop member 602 is used to fix the second hoop member 602 to the first hoop member 601. The groove bottom of the second hoop member 602 is provided with a through hole. The upper end of the first screw rod 603 is penetrated by the through hole of the groove bottom of the second hoop member 602. Two nuts are sleeved on the first screw rod 603.
