Novel inhaul cable type air pipe anti-seismic supporting hanger

Abstract

The invention discloses a novel inhaul cable type air pipe anti-seismic supporting hanger which comprises vertical C-shaped steel, lead screws, upper C-shaped steel and lower C-shaped steel, the number of the lead screws is two, the tops of the lead screws are connected with a main body structure, and the two ends of the upper C-shaped steel and the two ends of the lower C-shaped steel are connected with the lead screws correspondingly to form a rectangular space used for fixing an air pipe. The two pieces of vertical C-shaped steel are arranged and arranged on the two lead screws on the upper portion of the rectangular space in a sleeving mode respectively, one ends of the two first steel cables are connected with the main body structure, the other ends of the two first steel cables are connected with the upper C-shaped steel, and the two first steel cables are in an X shape. The problems that an inclined strut of a traditional anti-seismic support hanger is limited by installation space, and an anti-seismic hinge is prone to damage are solved, the steel consumption and the construction difficulty can be reduced, and the installation cost is saved; meanwhile, for the air pipe with the large dead weight, the novel inhaul cable type air pipe anti-seismic supporting and hanging frame can further improve the anti-seismic capacity.

Description

technical field [0001] The invention relates to the field of building anti-seismic technology, in particular to a novel cable-type air duct anti-seismic support and hanger. Background technique [0002] China is the country with the largest number of strong earthquakes on land in the world. The damage of the earthquake has led to the rapid development of domestic anti-seismic concepts and technologies. In addition to maintaining the original attention to the damage of the main structure under the action of the earthquake, people also pay attention to the non-main structures such as building electromechanical structures. The damage of the building is also slowly coming into view. With the official implementation of codes such as "Code for Seismic Design of Building Mechanical and Electrical Engineering" (GB50981-2014), the anti-seismic support and hanger has also made great progress. [0003] Traditional anti-seismic supports and hangers are mainly composed of anchors, reinfo...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure of the existing anti-seismic connectors is relatively complex, which will lead to high processing costs, and relevant scholars have pointed out that the anti-seismic connectors are prone to bending deformation or pull-off phenomenon under the action of earthquakes, which will lead to the destruction of the overall structure;

[0005] 2. During installation, it is often difficult to install the support and hanger structure in a narrow area due to the extra space occupied by the anti-seismic bracing, or due to the obstruction of the auxiliary electromechanical equipment of other adjacent buildings, the angle of the anti-seismic bracing is less than the 30° required by the code;

[0006] 3. There is obvious asymmetry in the anti-seismic support and hanger structure of the traditional air duct, which leads to a certain difference in its mechanical performance under positive and negative loading conditions: in the case of positive loading, the vertical support is mainly subjected to tension and the anti-seismic diagonal brace Mainly under compression; during reverse loading, the vertical supports are mainly under compression, and the anti-seismic diagonal braces are mainly under tension; as a result, under positive loading, the bottom anti-seismic connectors will rotate to a certain extent, and the bearing capacity will be weakened
