Description

Technical Field

[0001] The utility model relates to the technical field of assembled support structures, and more specifically to an assembled counter-support structure for a suspended ceiling in a large space. Background Art

[0002] Large public buildings have high floors, many internal equipment in the ceiling, dense pipelines, complex interior shapes and prominent layering. While satisfying the visual effect, they must also meet the needs of building use functions and later maintenance, resulting in high ceiling space and large spans. There are more and more indoor ceiling projects with large spans and large spaces, and with them come technical problems such as preventing the ceiling from floating up and down due to the upward force when it is subjected to negative wind pressure indoors, causing the ceiling to absorb upward and crack. For example, if the gypsum board ceiling is not supported, the ceiling will float up and down when it is subjected to negative pressure. Repeated repeated operations will cause cracks in the joints of the gypsum board ceiling. The solution to this problem is to increase the ceiling's counter-support or conversion layer.

[0003] The hanger rods of suspended ceilings are usually made of 6-10mm steel bars, which are not rigid enough to prevent the up and down floating of the suspended ceiling. However, by adding counter-supports, its rigidity is increased, which can prevent the panel from moving upward, thereby achieving the effect of controlling the deformation of the panel.

[0004] Traditional counter-support methods include the main keel tie method, the common tie method of the hanger, and the inverted triangle method. The length of the counter-support hanger is basically fixed and cannot be adjusted, and the hangers, diagonal stays, and transverse rods are mostly fixed by welding, bolt connection, blind rivets, or self-drilling nails; the adjustable range is small, and when encountering complex ceiling situations, effective tie cannot be formed. In actual operation, a variety of counter-support hangers of different specifications are often required, and they all need to be cut and cut on demand at the construction site, resulting in a lot of waste. In addition, the traditional counter-support method has a low degree of assembly and cannot be adjusted at will according to the on-site conditions while ensuring the integrity of the ceiling.
