Description

Technical Field

[0001] The present application relates to the technical field of building ceilings, and in particular to a steel truss roof ceiling support frame. Background Art

[0002] Buildings such as multi-functional conference halls have large areas and high functional requirements. Their roofs are generally designed as steel truss roofs. According to the specifications, "when the length of the hanger is greater than 1.5 meters, a counter-support should be set." The conventional practice is to install expansion bolts on the floor and weld angle steel, channel steel and other profiles as reverse supports to prevent the hanger from bending and deforming due to upward thrust due to excessive length.

[0003] However, when the hanger is longer, the diagonal rod is even longer, the required supporting material is huge, the diagonal rods are crossed and disordered and cannot be arranged, and there is also a conflict with the truss structure, maintenance passage, air duct, pipeline equipment, etc., making the construction difficult. In response to the above-mentioned related technologies, the applicant proposes a supporting structure that reduces the space occupied above the ceiling and maintains the stability of the ceiling. Utility Model Content

[0004] In order to provide enough space above the suspended ceiling of a large building and keep the suspended ceiling stable, the present application provides a steel truss roof suspended ceiling support frame.

[0007] By adopting the above technical solution, the connecting bracket extends downward, so that the space occupied above the lower chord of the truss is reduced, and the space utilization is more direct. The lower chord of the truss extending downward also shortens the length of the suspension rod, thereby ensuring that the main keel has a higher connection strength. At the same time, the elasticity of the elastic leather ring is used to provide counter-support for the main keel, further improving the stability of the main keel, thereby stabilizing the ceiling structure.

[0008] Preferably, the elastic leather ring includes a reed ring layer and a buffer rubber layer, the reed ring layer is arranged in a circular shape; and the buffer rubber layer covers the surface of the reed ring layer.

[0009] Preferably, the connecting bracket includes a setting cross bar, a lower probe rod and an extension sleeve rod, the setting cross bar abuts against the top of the elastic leather ring, and the setting cross bar extends horizontally and vertically to the lower chord of the truss; the lower probe rod is fixed to one side of the setting cross bar and extends downward, and the extended end abuts against the side wall of the lower chord of the truss corresponding to the elastic leather ring; the extension sleeve rod is fixed to the side of the lower probe rod opposite to the setting cross bar and extends upward, and the top end of the extension sleeve rod can be laterally sleeved on the adjacent setting cross bar.

[0010] Preferably, a clamping structure is provided at the top end of the extension sleeve rod, the clamping structure includes a clamping block and a fastening bolt, the clamping block is accommodated in the sleeve end of the extension sleeve rod, and the mounting cross bar is located between the inner side wall of the extension sleeve rod and the clamping block; the fastening bolt is threadedly connected to the sleeve end of the extension sleeve rod and is passed through the inner side of the extension sleeve rod, and one end of the fastening bolt is located inside the extension sleeve rod and is rotatably connected to the clamping block.

[0012] Preferably, the diagonal rod supports are arranged at intervals and tilted, with the top ends fixed to the roof and the bottom ends converging and fixed to the lower chord of the truss.

[0013] In summary, the present application includes at least one of the following beneficial technical effects: the connecting bracket extends downward, thereby reducing the space occupied above the lower chord of the truss, and the space utilization is more direct; the downward extending lower chord of the truss also shortens the length of the suspension rod, thereby ensuring that the main keel has a higher connection strength; at the same time, the elasticity of the elastic leather ring is used to provide counter-support for the main keel, further improving the stability of the main keel, thereby stabilizing the ceiling structure.

DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings.

[0018] The present application embodiment discloses a steel truss roof ceiling support frame, referring to Figure 1 , 2, including an inclined rod bracket 1 fixed to the roof and extending downward, the inclined rod bracket 1 is arranged at intervals and tilted, the top end is fixed to the roof, and the bottom end converges, a truss lower chord 2 is fixed at the convergence point of the bottom end of the inclined rod bracket 1, and the truss lower chord 2 is arranged horizontally at intervals, thereby forming a supporting frame body and being firmly connected to the roof.

[0019] Reference Figure 1 , 2 A connecting bracket 3 is mounted on the lower chord 2 of the truss, and an elastic leather ring 5 is sleeved on the outer side of the lower chord 2 corresponding to the connecting bracket 3. The elastic leather ring 5 includes a reed ring layer and a buffer rubber layer, and the reed ring layer is arranged in a circular shape; the buffer rubber layer covers the surface of the reed ring layer to buffer the friction between the lower chord 2 of the truss and the connecting bracket 3.

[0020] Reference Figure 1 , 2 The connecting bracket 3 includes a setting cross bar 31, a lower probe rod 32 and an extension sleeve rod 33. The setting cross bar 31 is abutted against the top of the elastic leather ring 5, and the setting cross bar 31 extends horizontally and vertically to the lower chord rod 2 of the truss; the lower probe rod 32 is fixed to one side of the setting cross bar 31 and extends downward, and the extended end abuts against the side wall of the elastic leather ring 5 corresponding to the lower chord rod 2 of the truss, thereby reducing the space occupied above the lower chord rod 2 of the truss; the extension sleeve rod 33 is fixed to the side of the lower probe rod 32 opposite to the setting cross bar 31, and extends upward, and the top end of the extension sleeve rod 33 can be horizontally sleeved on the adjacent setting cross bar 31, so as to conveniently adapt to the distance between the two lower chord rods 2 of the truss.

[0021] Reference Figure 1 , 2 A clamping structure 7 connected to the adjacent erection cross bar 31 is provided at the top end of the extension sleeve rod 33. The clamping structure 7 includes a clamping block 71 and a fastening bolt 72. The clamping block 71 is accommodated in the sleeve end of the extension sleeve rod 33, and the erection cross bar 31 is located between the inner side wall of the extension sleeve rod 33 and the clamping block 71; the fastening bolt 72 is screwed to the sleeve end of the extension sleeve rod 33 and is passed through the inner side of the extension sleeve rod 33. One end of the fastening bolt 72 is located in the extension sleeve rod 33 and is rotatably connected to the clamping block 71. When the fastening bolt 72 is rotated, the fastening bolt 72 drives the clamping block 71 to clamp the adjacent erection cross bar 31.

[0022] Reference Figure 1 , 2 The lower probe rod 32 is screwed with hanging rods 6 at intervals. The hanging rods 6 extend downward and are screwed to the main keel 4. The elastic leather ring 5 abuts against and drives the main keel 4 downward, thereby providing downward pressure on the main keel 4 to keep the main keel 4 stable, thereby making the ceiling stable.

[0023] The working process of the present application is: the connecting brackets 3 are plugged into each other and mounted on the lower chord 2 of the truss, an elastic leather ring 5 is sleeved between the connecting bracket 3 and the lower chord 2 of the truss to reduce friction, and then the fastening bolts 72 are tightened to stably connect the connecting brackets 3 to each other. Since the connecting bracket 3 extends downward after passing through the lower chord 2 of the truss, the space above the lower chord 2 of the truss is effectively expanded.

[0024] The suspension rod 6 is installed at the lower part of the connecting bracket 3, so as to reduce the distance between the suspension rod 6 and the main keel 4, thereby preventing the suspension rod 6 from being too long and affecting the strength; the main keel 4 is installed below the suspension rod 6, and the lower end of the elastic leather ring 5 abuts against the main keel 4, thereby providing counter-support for the main keel 4 and further improving the stability of the main keel 4.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
