Description

Technical Field

[0001] The present application relates to the technical field of steel membrane structures, and in particular to a steel membrane structure for suspended ceilings. Background Art

[0002] In the construction of large airports, PTEF membrane is usually used as the material for suspended ceilings to ensure that the shape of the suspended ceiling can meet the initial requirements, that is, to achieve spherical, curved and other shapes. When installing the PTEF membrane, it is usually necessary to first build a standard steel structure frame, and then lay the PTEF membrane on the steel frame to form a complete suspended ceiling.

[0003] The Chinese patent application number CN201520775786.4 discloses a cable-membrane steel structure factory roof. The factory roof includes multiple prestressed arch trusses arranged in parallel; a double-layer cable-membrane structure is arranged between two adjacent prestressed arch trusses, and the double-layer cable-membrane structure is connected to the truss; prestressed reinforced concrete reinforced arches are arranged at both ends of the factory roof, and the two ends of the prestressed reinforced concrete reinforced arches are fixed on reinforced concrete columns and fixedly connected to the cable-membrane structure.

[0004] In the above solution, the membrane is directly laid on the steel structure truss. However, when the burrs on the steel structure truss are not completely removed, or there are sharp protrusions on the truss, the membrane will be punctured, thereby affecting the stable connection between the membrane and the truss.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In order to prevent the film from being punctured during and after installation, the present application provides a steel membrane structure for a suspended ceiling.

[0007] The present application provides a steel membrane structure for suspended ceiling, which adopts the following technical solution:

[0008] A steel membrane structure for a suspended ceiling includes a membrane, a frame arranged at the end of the membrane, and a limiting assembly for limiting the position of the membrane relative to the frame. The limiting assembly is arranged on the frame and connected to the end of the membrane. The frame is also provided with a membrane stretching member abutting against the surface of the membrane. The membrane stretching member is arranged on the side of the membrane close to the frame and pushes the membrane away from the frame.

[0009] By adopting the above technical solution, the film is prevented from directly contacting the frame by using the film stretching member, thereby reducing the number of steel structures that the film has to contact during installation, making the film less likely to be damaged during installation and use.

[0010] Optional: The limit assembly includes a limit block set on the frame, and a limit rod passed through the limit block, a limit groove is opened at the lower end of the limit block, the limit groove passes through the two ends of the limit block, the end of the film is wound and fixed outside the limit rod, the limit rod is passed through the limit groove, and the diameter of the limit rod is larger than the width of the lower end opening of the limit groove.

[0011] By adopting the above technical solution, when the film needs to be connected to the limit block, the film can be wound on the limit rod and the limit rod can be inserted into the limit groove. The film can be connected to the limit rod as a whole, thereby making the connection between the film and the limit rod more stable.

[0012] Optionally: the limit block is also provided with a connecting component for connecting it to the frame, and the connecting component includes a plurality of connecting bolts arranged on the limit block and connecting nuts threadedly connected to the connecting bolts, a connecting groove is provided at the upper end of the limit block, the connecting groove passes through the two ends of the limit block, the bottom width of the connecting groove is larger than the width of the upper end opening of the connecting groove, the head of the connecting bolt is embedded in the connecting groove, the connecting bolt is passed through the frame and connected to the connecting nut.

[0013] By adopting the above technical solution, the vertical adjustment of the limit assembly is achieved by utilizing the cooperation of the connecting bolts and the connecting nuts, thereby adjusting the tension of the film.

[0014] Optionally: a plurality of fixed ears are provided on the frame, and movable ears are detachably connected to the fixed ears, and the connecting components and the film stretching parts are both connected to the movable ears.

[0015] By adopting the above technical solution, during installation, the frame can be installed first, and then the movable ears can be connected to the fixed ears, making the installation of the film more convenient.

[0016] Optionally: a connecting piece is commonly fixed to one end of the movable ears away from the fixed part, a vertical baffle is arranged on the side wall of the connecting part away from the fixed part, the stretching film part is arranged at one end of the vertical baffle away from the connecting part, a horizontal baffle is arranged at one end of the vertical baffle close to the frame, and the connecting bolt is passed through the horizontal baffle.

[0017] By adopting the above technical solution, the film passes through the lower end of the limiting groove and bypasses from under the film stretching member, thereby further reducing the contact area between the film and the steel structure, making the surface of the film less likely to be punctured by sharp structures such as burrs on the steel structure.

[0018] Optionally: a plurality of first reinforcement members are arranged on the end surface of the vertical baffle away from the frame, and the first reinforcement members are fixed to the connecting member.

[0019] By adopting the above technical solution, the first reinforcing member is used to enhance the connection strength between the vertical baffle and the connecting member, so that when the vertical baffle is subjected to horizontal force, the vertical baffle is not easily deformed and maintains a vertical state, so that the tension of the film is not easily affected.

[0020] Optionally: a plurality of second reinforcement members are provided on both vertical side walls of the fixing ear, and the second reinforcement members are arranged vertically and are connected to the frame.

[0021] By adopting the above technical solution, the second reinforcing member is used to limit the strength of the fixing ear, so that the fixing ear will not bend directly when subjected to horizontal force, thereby making the tension of the film less likely to be affected.

[0022] Optionally, the fixed ear and the movable ear are partially overlapped, and a pin is commonly provided on the fixed ear and the movable ear.

[0023] By adopting the above technical solution, when connecting the fixed ear and the movable ear, it is only necessary to directly insert the pin shaft into the connection between the fixed ear and the movable ear, so that the relative position between the fixed ear and the movable ear is limited, and the connection between the fixed ear and the movable ear is also made more convenient.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Use the film stretching piece to apply downward pressure to the film, so that the film is not easily in direct contact with the frame and other mechanical structures, and the film is not easily damaged by scratches;

[0026] 2. Use the limiting assembly to make the film extend downward and bypass the lower end of the film stretching member, thereby further preventing the film from directly contacting the frame and other mechanical structures, making the film less likely to be scratched.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] The present application discloses a steel membrane structure for a suspended ceiling, such as Figure 1 and Figure 2 As shown, it includes a film 1, a frame 2 arranged at the end of the film 1, and a limiting assembly 3 that limits the position of the film 1 relative to the frame 2. The frame 2 is arranged in a rectangular shape, the film 1 is arranged in the inner cavity of the frame 2, and a gap is left between the film 1 and the inner wall of the frame 2. The limiting assembly 3 is connected to the edges of the frame 2 respectively, and the limiting assembly 3 includes a limiting block 31 arranged parallel to the edge of the frame 2, and a limiting rod 32 inserted into the limiting block 31. A limiting groove 311 is provided at the lower end of the limiting block 31, and the limiting groove 311 penetrates the two ends of the limiting block 31. The longitudinal cross-section of the limiting groove 311 perpendicular to the length direction of the limiting block 31 is circular, and the limiting rod 32 is inserted into the limiting groove 311, and the diameter of the limiting rod 32 is greater than the width of the lower end opening of the limiting groove 311, so that the limiting rod 32 will not fall off directly from the lower end opening of the limiting groove 311. The end of the film 1 is wound on the limiting rod 32 and fixed to the film 1 itself by glue, so that the film 1 and the limiting rod 32 can be connected, so that the position of the end of the film 1 can be stably limited.

[0032] A plurality of horizontally arranged fixed ears 21 are welded on the inner wall of the frame 2 along its length direction. The end of the fixed ear 21 away from the frame 2 to which it is connected is detachably connected to a movable ear 22. The fixed ear 21 and the movable ear 22 partially overlap, and a pin is passed through the overlapping part of the fixed ear 21 and the movable ear 22, so that the connection between the fixed ear 21 and the movable ear 22 is achieved through the pin.

[0033] The lower ends of the movable ears 22 located on the edges of the same frame 2 are welded and fixed with a connecting piece 23 parallel to the edge of the frame 2. The connecting piece 23 is a round tube in this embodiment. A vertical baffle 24 arranged parallel to the round tube is welded and fixed to the lower end of the round tube. A horizontal baffle 25 arranged horizontally is arranged at one end of the vertical baffle 24 close to the fixed ear 21 connected to it. A connecting assembly 4 is arranged on the limit block 31 to connect it with the horizontal baffle 25. The connecting assembly 4 includes a plurality of connecting bolts 41 arranged on the limit block 31 and a plurality of connecting nuts 42 respectively threadedly connected to the connecting bolts 41. An inverted T-shaped connecting groove 312 is provided on the upper end surface of the limit block 31. The connecting groove 312 penetrates the two end surfaces of the limit block 31, and the width of the bottom surface of the connecting groove 312 is greater than the width of the upper end opening. The head of the connecting bolt 41 is embedded in the connecting groove 312, and the lower end of the head of the connecting bolt 41 abuts against the bottom of the connecting groove 312. The rod of the connecting bolt 41 passes through the horizontal baffle 25 and is connected to the connecting nut 42, so that the limit block 31 can be stably connected to the horizontal baffle 25.

[0034] A film stretching member 26 parallel to the length direction of the limit block 31 is welded and fixed below the vertical baffle 24. In this embodiment, the film stretching member 26 is a round steel tube. The lower end of the film stretching member 26 is lower than the lower end surface of the limit block 31, and the film stretching member 26 abuts against the upper end surface of the film 1, so that the film 1 will not directly contact the frame 2, etc., so that the film 1 can remain in a tensioned state.

[0035] A first elastic member 27 is also provided at the lower end of the film stretching member 26, and a second elastic member 33 is also provided on the inner wall of the limiting groove 311. The first elastic member 27 and the second elastic member 33 are both maintained in contact with the film 1, so that the film 1 is not easy to contact the surface of the steel structure such as the frame 2, so that the film 1 is not easy to be damaged.

[0036] Since the fixed ear 21 is subjected to horizontal tension during use and is prone to deformation, second reinforcement members 28 are provided on both vertical side walls of the fixed ear 21. The second reinforcement members 28 are arranged vertically and are fixed to the inner wall of the frame 2. The second reinforcement members 28 are used to limit the deformation of the fixed ear 21 in the horizontal direction, so that the fixed ear 21 is not easily deformed in the horizontal direction, and the connection between the fixed ear 21 and the movable ear 22 is more stable.

[0037] Since the connecting member 23 is directly connected to the vertical baffle 24, and the vertical baffle 24 is subjected to the force exerted by the film 1 away from the frame 2, the vertical baffle 24 is easily bent, thereby affecting the tension of the film 1. Therefore, a plurality of first reinforcing members 29 are arranged along the length direction of the vertical baffle 24 on the side wall of the vertical baffle 24 away from the frame 2, and the first reinforcing members 29 are fixed to the connecting member 23, thereby improving the overall strength of the vertical baffle 24, making it difficult for the vertical baffle 24 to bend when subjected to force, and making the tension effect of the film 1 not easily affected.

[0038] The implementation principle of this embodiment is: during installation, the frame 2 is first installed and fixed, and then the film 1 connected to the limiting component 3 is moved to the bottom of the film stretching member 26, and then the limiting component 3 is connected to the horizontal baffle 25 through the connecting bolt 41, and the movable ear 22 is moved to overlap and connect with the fixed ear 21, and then the position of the connecting nut 42 is adjusted to keep the film 1 taut and abut against the lower end of the film stretching member 26, and the installation of the film 1 is completed.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
