Description

Technical Field

[0001] This application relates to the field of ceiling construction technology, and in particular to an adjustment device for a large metal mesh ceiling. 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. When a large metal mesh deforms due to its own weight, the amount of deformation is often large. If the existing tensioning metal mesh ceiling system is used to tension the large metal mesh, it is not only time-consuming, but also has a limited tensioning effect. The existing metal mesh ceiling system cannot balance the relationship between the tensioning force of the large metal mesh and its own weight deformation, and it cannot guarantee the safety of the large metal mesh ceiling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a large-scale metal mesh ceiling system, which solves the technical problem that existing metal mesh ceiling adjustment systems cannot balance the relationship between the tensioning force and self-weight deformation of large metal meshes.

The tension rod is suspended from the steel frame base, and the upper end of the tension rod passes through the steel frame base. The length of the tension rod extending out of the steel frame base is adjustable. When the tension rod moves up and down, the metal mesh drives the large roller to rotate.

[0008] In one embodiment, the steel frame base is provided with a vertical through hole, the upper end of the tension rod passes through the vertical through hole, a nut is provided 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 sleeved on the tension rod, and the tension rod is provided with external threads.

[0009] In one embodiment, a washer and an angle steel are arranged sequentially from top to bottom between the nut and the upper surface of the vertical through hole.

[0010] In one embodiment, both the large roller and the small roller are arranged along the width direction of the steel frame base. The diameter of the large roller is 120mm, and the diameter of the small roller is 50mm. The fixing plate and the fixing rod are fixedly connected by welding.

[0011] In one embodiment, the adjustment device includes a plurality of tension rods and a plurality of fixing rods, all of which are arranged parallel to each other along the width direction of the steel frame base.

[0012] In one embodiment, the metal mesh layer further includes downwardly curved arc-shaped ribs fixed below the steel frame base layer.

[0013] In one embodiment, the arcuate 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 arcuate rib.

[0014] In one embodiment, the second connecting hole is an oblong hole arranged along the length of the steel frame base, and the connecting rope is a steel wire rope.

[0025] To better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , 2 The present embodiment provides an adjustment device for a large metal mesh ceiling. The large metal mesh ceiling includes a steel frame base 1 and a metal mesh layer 4. The steel frame base 1 is rectangular, and the metal mesh layer 4 includes a metal mesh 402. The metal mesh 402 is arranged below the steel frame base 1 along the length direction of the steel frame base 1. Adjustment devices 8 are provided at both the front and rear ends of the metal mesh 402. The metal mesh 402 is connected to the steel frame base 1 through the adjustment devices 8. The adjustment devices 8 can adjust the distance between the end of the metal mesh 402 and the upper surface of the steel frame base 1.

[0027] The adjusting device 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 installed on the front and rear sides of the steel frame base 1. The upper end of the fixing rod 805 is fixed to the steel frame base 1, and the lower end of the fixing rod 805 is fixedly installed with the fixing plate 804. The large roller 801 is rotatably mounted on the fixing plate 804. The metal mesh 402 is installed close to the outer surface of the large roller 801. The small roller 802 is installed on the metal... At the front and rear ends of the mesh 402, the large roller shaft 801 and the small roller shaft 802 are both set along the width direction of the steel frame base 1. The lower end of the tension rod 803 is fixedly provided 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.

[0028] 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. A diagonal brace 807 is also provided between the fixing rod 805 and the steel frame base 1 to improve the stability of the adjustment device. 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 uses a large rolling roller 801 to change the pre-tension force of the metal mesh 402 from horizontal to vertical. The dynamic friction between the metal mesh 402 and the large roller 801 reduces the vertical pre-tension force acting on the steel frame base 1, thus avoiding damage to the steel frame base 1 when tensioning the large metal mesh.

[0029] In this embodiment, the fixing plate 804 and the fixing rod 805 are fixedly connected by welding. Both the fixing rod 805 and the diagonal brace 807 are angle steel to improve the load-bearing capacity of the adjustment device. The adjustment device 8 includes multiple tension rods 803 and multiple fixing rods 805. The multiple tension rods 803 are arranged parallel to each other along the width direction of the steel frame base 1, and the multiple fixing rods are arranged parallel to each other along the width direction of the steel frame base 1. By setting multiple tension rods 803 and multiple fixing rods 805, the large roller shaft 801 and the small roller shaft 802 can be stably supported.

[0030] The metal mesh layer 4 also includes a downwardly curved arc rib 401, which is fixed below the steel frame base 1. Both the arc rib 401 and the metal mesh 402 are arranged along the length of the steel frame base 1. The metal mesh 402 is connected to the arc rib 401 by a connecting rope 405 and is arranged along the lower surface of the arc rib 401.

[0031] The arc-shaped rib plate 401 is provided with multiple second connecting holes 403. A connecting rope 405 passes through the second connecting holes 403 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 provided 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 devices 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] 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, the metal mesh 402 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 tightening force 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 tightening force of the metal mesh 402 is too small, the shape of the metal mesh will not be uniform when suspended from the ceiling. Setting adjustment devices at both ends of the metal mesh 402 can 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 can generate a suitable tightening force. 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, so as to maintain the shape of the large metal mesh ceiling for a long time.

[0033] The large metal mesh ceiling also includes a transition layer 2 and a metal plate layer 3. 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.

[0034] The steel frame base 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 transfer layer 2 includes metal pipes 201, and multiple metal pipes 201 are fixed to the lower ends of the vertical steel frames 102 along the length of the steel frame base 1. 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. To enhance the load-bearing capacity of the transfer layer 2, the transfer layer 2 also includes transverse connecting rods 202, and multiple transverse connecting rods 202 are fixed to the upper surface of the metal pipes 201 along the width of the steel frame base 1. In this embodiment, the transverse connecting rods 202 are galvanized angle steel, and the metal pipes 201 are galvanized square tubes.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application 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 methods of the application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all of them should be covered within the scope of the technical solutions claimed in this application.
