Description

Technical Field

[0001] The utility model relates to the technical field of building ceilings, in particular to a composite suspension rod type counter-support device. Background Art

[0002] In the field of modern architecture, with the increasing complexity and personalization of architectural design, higher requirements are placed on the safety, stability and space utilization efficiency of building structures. Especially for large-span spatial structures, special-shaped building forms or buildings that need to carry heavy equipment, traditional single hanger systems or support methods are often difficult to meet their complex force requirements and aesthetic design standards.

[0003] On the one hand, traditional hanger systems mostly use a single material or simple structure, such as simple cable suspension or concrete support beams. These methods have certain limitations when facing asymmetric load distribution, large deformation control, or durability issues in long-term service. For example, a single material may not be able to take into account strength, toughness, and economy at the same time, and a simple support structure is difficult to accurately adapt to complex spatial morphological changes.

[0004] On the other hand, with the increasing requirements for energy conservation and environmental protection of buildings, the control of the deadweight of the structure has become increasingly strict. Traditional reinforcement and support methods often lead to additional material consumption and an increase in the deadweight of the structure, which will affect the overall energy efficiency and environmental adaptability. China Invention Publication No. CN114250903A discloses a suspended ceiling counter-support and a counter-support suspended ceiling construction method, wherein the suspended ceiling counter-support includes a sleeve, a hanger and concrete. Among them, the hanger is inserted into the sleeve, and the hanger includes a main body section located in the sleeve, and the two ends of the main body section extend from the two ends of the sleeve to form an upper connecting section and a lower connecting section; the upper connecting section is used to connect to the structural floor; the lower connecting section is used to connect to the ceiling panel; wherein a casting channel is formed between the outer peripheral surface of the main body section and the inner wall surface of the sleeve; the concrete is arranged in the casting channel. The suspended ceiling counter-support of the invention provides a new suspended ceiling counter-support, thereby reducing the cost of manufacturing the suspended ceiling counter-support. However, the application requires actual assembly at the construction site throughout the entire process. Although it can adapt to different construction environments, it greatly reduces the on-site construction efficiency and cannot be reused. Therefore, a new type of anti-support device in the form of a composite hanger is urgently needed to solve the above problems. Utility Model Content
