Inclined strut for anti-seismic support hanger and connection component thereof

Abstract

The invention discloses an inclined strut for an anti-seismic support hanger and a connection component of the inclined strut. The inclined strut comprises a center screw rod, an outer pipe sleeve andbent plates. The center screw rod is correspondingly arranged inside the outer pipe sleeve, the two ends of the center screw rod are convexly arranged at the two ends of the outer piper sleeve, the two ends of the outer pipe sleeve are provided with a first centering gasket and a second centering gasket, the first centering gasket is fixedly arranged on the center screw rod through a first pressing nut, the second centering gasket is fixedly arranged on the center screw rod trough a second pressing nut, the two ends of the center screw rod are correspondingly arranged on the bent plates, andthe two bent plates are correspondingly fixed to a steel frame of a building structure and a hanging electromechanical device or pipeline. Structure stress is simple, the adjustable bent plates are adopted to achieve adjustment of different inclined strut angles on an installation site, and the connection component with the high strength can be made from a small amount of materials by adopting thebent plates of a boat-shaped structure.

Description

technical field [0001] The invention relates to a diagonal brace for an anti-seismic support and hanger and a connecting member thereof. Background technique [0002] For building water supply and drainage, heating, ventilation, air conditioning, gas, heat, electricity, communication, fire protection and other mechanical and electrical engineering for earthquake resistance, reduce earthquake damage, prevent secondary disasters, avoid casualties, reduce economic losses, relevant national standards and industry standards It is required to set up anti-seismic supports for building electromechanical equipment and pipelines, firmly connect electromechanical projects such as pipelines, cable bridges, and ventilation ducts with building structures, and transmit seismic forces on electromechanical equipment and pipelines. "Code for Seismic Design of Buildings" clearly points out that friction force shall not be used as resistance against earthquake. However, the structure recommend...

AI Technical Summary

Problems solved by technology

However, the current structure recommended by the relevant standards adopts the tight connection between the top of the screw and the surface of the C-shaped channel steel to transmit the seismic force, which obviously does not meet the requirements.

Secondly, the magnitude of the seismic force suffered by electromechanical equipment and pipelines of different quality varies greatly. Relevant documents require the use of diagonal braces and connectors of the same structural size for large and small pipelines, which will inevitably result in bloated seismic structures for small pipelines and large pipelines. severe lack of strength

In addition, when the anti-seismic diagonal brace with C-shaped channel steel at the top is subjected to earthquake force, the load center does not pass through the center of gravity of the section of the C-shaped channel steel, which makes the stress condition of the C-shaped channel steel worse during earthquake resistance
