Description

Technical Field

[0001] This invention relates to the field of ceiling construction technology, and in particular to a large-scale metal mesh ceiling system. Background Technology

[0002] Metal mesh ceilings not only offer excellent visual appeal but also boast advantages such as ease of maintenance and ventilation. More and more buildings are choosing metal mesh ceilings, such as the tensioned metal mesh ceiling system disclosed in Chinese Patent CN 112064879. This system includes an upper support, a lower support, and a keel connecting the upper and lower supports. Multiple pull rings are detachably installed on the inner wall of the keel, and pull rods are hung on the pull rings. Hooks are movably installed on the pull rods, and these hooks are attached to the intersection of the wire rope and the metal strip. Each hook is equipped with a locking component for securing the metal strip. The upper support is equipped with a traction device for fixing the metal rod, and the lower support is equipped with a fixing device for fixing the metal mesh. The keel is equipped with a suspension device for suspending the metal strip.

[0003] The metal mesh in the aforementioned patent is the same size as conventional metal mesh, and its length is often less than ten meters. When a metal mesh ceiling is installed on the top of a large hall, the required length of the metal mesh is often greater than twenty meters. The weight of a single large metal mesh is approximately one ton. Existing metal mesh ceiling systems not only cannot fix the extremely heavy metal mesh to the top of a large hall, but also cannot balance the relationship between the tension of the large metal mesh and its own weight. Therefore, existing metal mesh ceiling systems are not suitable for metal mesh ceilings in large halls. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, this application provides a large-scale metal mesh ceiling system to solve the technical problem that existing metal mesh ceiling systems are not suitable for large hall metal mesh ceilings.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] A large-scale metal mesh ceiling system includes a steel frame base, a transition layer, a metal plate layer, and a metal mesh layer. The steel frame base is rectangular. The transition layer is fixedly installed at the bottom of the steel frame base. The metal plate layer is installed below the transition layer and is fixedly connected to the transition layer via a first connecting component. The metal mesh layer is installed below the metal plate layer and is fixedly connected to the transition layer via a second connecting component. The metal mesh layer includes arc-shaped ribs and a metal mesh, both of which are arranged along the length of the steel frame base. The arc-shaped ribs have a downward curvature. The metal mesh is connected to the arc-shaped ribs via connecting ropes and is arranged along the lower surface of the arc-shaped ribs. The front and rear ends of the metal mesh are connected to the steel frame base via adjusting components, which can adjust the distance between the ends of the metal mesh and the upper surface of the steel frame base.

[0007] In one embodiment, the arc-shaped rib is provided with a plurality of second connecting holes, and a connecting rope passes through the second connecting holes and the metal mesh to suspend the metal mesh on the lower surface of the arc-shaped rib.

[0008] In one embodiment, the second connecting hole is a waist-shaped hole arranged along the length of the steel frame base, and the connecting rope is a steel wire rope.

[0009] In one embodiment, the steel frame base includes a horizontal steel frame and a vertical steel frame, the horizontal steel frame being fixed to the indoor ceiling, and the upper ends of a plurality of vertical steel frames being fixed to the horizontal steel frame; the conversion layer includes metal pipes, a plurality of metal pipes being fixed to the lower ends of the vertical steel frames along the length of the steel frame base; the metal plate layer includes a plurality of metal plates, the metal plates being fixed below the metal pipes by a first connecting assembly.

[0010] In one embodiment, the second connecting assembly includes a first clamp, a second clamp, a first lead screw, and a connecting piece. Both the first and second clamps are U-shaped grooves. The bottom of the groove of the first clamp matches the metal pipe, and the opening of the first clamp faces downwards, snapping onto the metal pipe. The groove walls of both the first and second clamps are provided with through holes of the same diameter. The open end of the first clamp can be inserted into the second clamp along the groove wall. When the open end of the first clamp is inserted into the second clamp, a fastener passes through both the first and second clamps. The groove wall has through holes to fix the second clamp to the first clamp. The bottom of the groove of the second clamp has through holes. The upper end of the first screw passes through the through hole at the bottom of the groove of the second clamp. Two nuts are fitted on the first screw. The two nuts on the first screw are located on the upper and lower surfaces of the bottom of the groove of the second clamp, respectively. The first screw is fixed to the second clamp by the cooperation of the two nuts and the first screw. A metal plate passes through the first screw. A connecting piece is fixed to the lower end of the first screw. The lower end of the connecting piece is fixedly connected to the arc-shaped rib.

[0011] In one embodiment, the conversion layer further includes transverse connecting rods, a plurality of which are fixed to the upper surface of the metal tube along the width direction of the steel frame base.

[0012] In one embodiment, the transverse connecting rod is a galvanized angle steel, and the metal tube is a galvanized square tube.

[0013] In one embodiment, the metal mesh layer includes multiple metal meshes arranged parallel to each other along the width direction of the steel frame base. Above each metal mesh, multiple arc-shaped ribs with the same curvature are arranged parallel to each other along the width direction of the steel frame base. A light strip assembly is arranged between adjacent metal meshes, and the light strip assembly is arranged along the length direction of the steel frame base.

[0014] In one embodiment, the light strip assembly includes a second lead screw, a base plate, and a lamp tube. The lamp tube is disposed on the lower surface of the base plate and is fixedly connected to the base plate. The base plate is provided with second lead screws at both the left and right ends. The left and right ends of the base plate are fixed to the lower ends of the second lead screws, and the upper ends of the second lead screws are fixed to the conversion layer.

[0015] In one embodiment, the adjusting assembly includes a large roller, a small roller, a tension rod, a fixing plate, and a fixing rod. The fixing rod is located at the front and rear ends of the transition layer. The upper end of the fixing rod is fixed to the steel frame base layer. The lower end of the fixing rod is provided with a fixing plate. The large roller is rotatably mounted on the fixing plate. The metal mesh is set close to the outer surface of the large roller. The small roller is located at the front and rear ends of the metal mesh. Both the large and small rollers are arranged along the width direction of the steel frame base layer. The tension rod passes through the steel frame base layer and is located on the side of the fixing rod away from the transition layer. A collar is fixedly provided at the lower end of the tension rod. The small roller passes through the collar. The tension rod is suspended from the steel frame base layer. The upper end of the tension rod passes through the steel frame base layer. The length of the tension rod extending beyond the steel frame base layer is adjustable. When the tension rod moves up and down, the metal mesh drives the large roller to rotate.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0017] The large metal mesh ceiling system of this invention arranges a large metal mesh along downward-curving arc-shaped ribs. The front and rear ends of the mesh are connected to a steel frame base via adjusting components. This not only maintains the shape of the large metal mesh during ceiling installation but also stably fixes it to the steel frame base. The adjusting components at both ends of the mesh can adjust the distance between the ends of the mesh and the steel frame base to generate appropriate tension. Furthermore, when the mesh deforms due to its own weight, adjustments can be made from both ends to ensure that the deformed mesh remains aligned with the lower surface of the arc-shaped ribs, thus maintaining the shape of the large metal mesh ceiling for a long time. This invention can fix a massive metal mesh to the ceiling of a large hall, balancing the relationship between the tension of the large metal mesh and its own weight deformation, overcoming the shortcomings of existing large metal mesh ceiling technologies.

[0027] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical connection or internal connection between two components. They can be direct connection or indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0028] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5 The embodiment described above provides a large-scale metal mesh ceiling system, including a steel frame base 1, a transition layer 2, a metal plate layer 3, and a metal mesh layer 4. The steel frame base 1 is rectangular. The transition layer 2 is fixedly installed at the bottom of the steel frame base 1. The metal plate layer 3 is installed below the transition layer 2 and is fixedly connected to the transition layer 2 via a first connecting component 5. The metal mesh layer 4 is installed below the metal plate layer 3 and is fixedly connected to the transition layer 2 via a second connecting component 6. The metal mesh layer 4 includes arc-shaped ribs 401 and metal mesh 4. 02. Both the arc-shaped rib 401 and the metal mesh 402 are set along the length 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 set along the lower surface of the arc-shaped rib 401. Adjustment components 8 are set at both the front and rear ends of the metal mesh 402. The metal mesh 402 is connected to the steel frame base 1 by the adjustment components 8. The adjustment components 8 can adjust the distance between the end of the metal mesh 402 and the upper surface of the steel frame base 1.

[0030] Setting the metal mesh 402 along the lower surface of the arc-shaped rib 401 not only maintains the shape of the large metal mesh when suspended in the ceiling, but also stably fixes the metal mesh to the steel frame base 1. Because the length of the metal mesh in a large metal mesh ceiling is greater than or equal to 20 meters, the metal mesh needs to be connected to the arc-shaped rib plate 401 by thousands of connecting ropes. When the metal mesh 402 is suspended from the ceiling, it will exert an upward force on the arc-shaped rib plate 401, and the front and rear ends of the metal mesh will also exert a downward force on the steel frame base. If the tension of the metal mesh 402 is too large, it will cause the metal mesh to break or the steel frame base to deform. If the tension of the metal mesh 402 is too small, the shape of the metal mesh will not be uniform when suspended from the ceiling. Adjustment components are set at both ends of the metal mesh 402. When the metal mesh ceiling is suspended, the distance between the end of the metal mesh 402 and the steel frame base 1 can be adjusted to generate a suitable tension force for the metal mesh 402. It can also be adjusted from both ends of the metal mesh 402 when the metal mesh 402 deforms due to its own weight, so that the deformed metal mesh can still be set along the lower surface of the arc-shaped rib plate 401 to maintain the shape of the large metal mesh ceiling for a long time.

[0031] The arc-shaped rib plate 401 is provided with multiple second connecting holes 404. A connecting rope 405 passes through the second connecting holes 404 and the metal mesh 402 to suspend the metal mesh 402 on the lower surface of the arc-shaped rib plate 401. In this embodiment, the second connecting hole 404 is a waist-shaped hole arranged along the length of the steel frame base 1, with a length of 20mm. By providing a waist-shaped hole in the arc-shaped rib plate 401, the connecting rope 405 can move left and right when connected to the metal mesh 402. This allows the metal mesh 402 to move left and right when the adjustment components at both ends of the metal mesh 402 are working, reducing the tension generated during adjustment and improving safety. To ensure the load-bearing capacity of the connecting rope 405, in this embodiment, the connecting rope 405 is a steel wire rope.

[0032] The steel frame base layer 1 includes a horizontal steel frame 101 and a vertical steel frame 102. The horizontal steel frame 101 is fixed to the indoor ceiling, and the upper ends of multiple vertical steel frames 102 are fixed to the horizontal steel frame 101. The transition layer 2 includes metal pipes 201, and multiple metal pipes 201 are fixed along the length of the steel frame base layer 1 to the lower ends of the vertical steel frames 102. The metal plate layer 3 includes multiple metal plates, and the metal plates are fixed below the metal pipes 201 by a first connecting assembly 5.

[0033] The second connecting assembly 6 includes a first clamp 601, a second clamp 602, a first lead screw 603, and a connecting piece 604. Both the first clamp 601 and the second clamp 602 have U-shaped grooves. The bottom of the groove of the first clamp 601 matches the metal pipe 201, and the opening of the first clamp 601 is downward, snapping onto the metal pipe 201. The groove walls of both the first clamp 601 and the second clamp 602 have through holes of the same diameter. The open end of the first clamp 601 can be inserted into the second clamp 602 along the groove wall. When the open end of the first clamp 601 is inserted into the second clamp 602, the fastener passes through the first clamp 601 and the second clamp 602. The second clamp 602 has a through hole in the groove wall, thereby fixing the second clamp 602 to the first clamp 601. The bottom of the groove of the second clamp 602 is provided with a through hole. The upper end of the first lead rod 603 passes through the through hole at the bottom of the groove of the second clamp 602. Two nuts are sleeved on the first lead rod 603. The two nuts on the first lead rod 603 are located on the upper and lower surfaces of the bottom of the groove of the second clamp, respectively. The first lead rod 603 is fixed to the second clamp 602 by the cooperation of the nuts and the first lead rod. The first lead rod 603 passes through the metal plate. The lower end of the first lead rod 603 is fixed with a connecting piece 604. The lower end of the connecting piece 604 is fixedly connected to the arc-shaped rib plate 401. In this embodiment, the arc-shaped rib plate 401 is provided with a plurality of first connecting holes 403, and the lower end of the connecting piece 604 is provided with a through hole. The fastener passes through the first connecting holes 403 and the through hole on the connecting piece 604 to fix the lower end of the connecting piece 604 to the arc-shaped rib plate 401. The detachable connection between the connecting piece 604 and the arc-shaped rib plate 401 reduces the stress on the second connecting component 6 when suspended in the ceiling and improves the safety of installation.

[0034] To enhance the load-bearing capacity of the transfer layer 2, the transfer layer 2 also includes transverse connecting rods 202, multiple transverse connecting rods 202 fixed along the width direction of the steel frame base layer 1 to the upper surface of the metal pipe 201. In this embodiment, the transverse connecting rods 202 are galvanized angle steel, and the metal pipe 201 is a galvanized square tube.

[0035] The metal mesh layer includes multiple metal meshes 402 arranged parallel to each other along the width direction of the steel frame base 1. Above each metal mesh 402, multiple arc-shaped ribs 401 with the same curvature are arranged parallel to each other along the width direction of the steel frame base 1. A light strip assembly 7 is arranged between adjacent metal meshes 402, and the light strip assembly 7 is arranged along the length direction of the steel frame base 1. The light strip assembly 7 includes a second lead screw 701, a base plate 702, and a lamp tube 703. The lamp tube 703 is disposed on the lower surface of the base plate 702 and is fixedly connected to the base plate 702. The second lead screw 701 is provided at both the left and right ends of the base plate 702, and the left and right ends of the base plate 702 are fixed to the lower ends of the second lead screw 701. The upper end of the second lead screw 701 is fixed to the conversion layer 2. In this embodiment, the second lead screw 701 is vertically fixed to the transverse connecting rod, and the lower surface of the lamp tube has the same height and curvature as the lower surface of the metal mesh.

[0036] The adjusting assembly 8 includes a large roller 801, a small roller 802, a tension rod 803, a fixing plate 804, and a fixing rod 805. The fixing rod 805 is located at the front and rear ends of the conversion layer 2. The upper end of the fixing rod 805 is fixed to the steel frame base layer 1, and the lower end of the fixing rod 805 is provided with the fixing plate 804. The large roller 801 is rotatably mounted on the fixing plate 804. The metal mesh 402 is set close to the outer surface of the large roller 801. The small roller 802 is located at the front and rear ends of the metal mesh 402. The large roller 801 and the small roller 802... 02 are all set along the width direction of the steel frame base 1. The tension rod 803 passes through the steel frame base 1. The tension rod 803 is set on the side of the fixed rod 805 away from the conversion layer 2. The lower end of the tension rod 803 is fixedly set with a collar 806. The small roller shaft 802 passes through the collar. The tension rod 803 is suspended on the steel frame base 1. The upper end of the tension rod 803 passes through the steel frame base 1. The length of the tension rod 803 extending out of the steel frame base 1 is adjustable. When the tension rod 803 moves up and down, the metal mesh 402 drives the large roller shaft 801 to rotate.

[0037] The steel frame base 1 has a vertical through hole. The upper end of the tension rod 803 passes through the vertical through hole, and a nut is placed above the vertical through hole. The nut is set on the steel frame base. The inner diameter of the vertical through hole is smaller than the inner diameter of the nut. The nut is fitted onto the tension rod 803, which has external threads. The length of the tension rod 803 extending out of the steel frame base 1 can be adjusted by the cooperation between the tension rod 803 and the nut, thereby adjusting the tensioning force of the metal mesh 402. A washer and an angle steel are also arranged sequentially from top to bottom between the nut and the upper surface of the vertical through hole.

[0038] A diagonal brace 807 is also provided between the fixed rod 805 and the steel frame base 1 to improve the stability of the adjustment assembly. In this embodiment, the diameter of the large roller shaft 801 is 120mm, and the diameter of the small roller shaft 802 is 50mm. This application can change the pre-tension force of the metal mesh 402 from horizontal to vertical by using the rolling large roller shaft 801. The dynamic friction between the metal mesh 402 and the large roller shaft 801 reduces the vertical pre-tension force acting on the steel frame base 1 and reduces the tension of the metal mesh 402 fixed on the arc-shaped rib plate 401, thereby improving the safety and integrity of the large metal mesh ceiling system.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
