Description

TECHNICAL FIELD

[0001] The utility model relates to a field of air pipe support, concretely is a rectangular air pipe anti -seismic support. BACKGROUND

[0002] In earthquake disasters, the dynamic stability of building auxiliary pipe network is directly related to the secondary disaster prevention and control capacity. The failure of building mechanical and electrical suspension system can easily cause secondary damage, which makes the seismic design of pipeline engineering an important part of modern building safety system. The mechanical properties of the traditional pipe network fixing system mainly respond to the plane static force under the action of the conventional load, but it is difficult to adapt to the three-dimensional composite vibration mode caused by the seismic wave. When the multi-frequency and variable vector impact load generated by the seismic wave acts on the pipeline system, this rigid connection system is easy to produce structural fatigue damage under the action of alternating stress, and then lead to the failure of support node.

[0003] Although the Chinese patent "a single pipe side longitudinal anti-seismic support of air pipe" (authorized announcement number CN 210440788 U) and the Chinese patent "a rectangular air pipe anti-seismic support" (authorized announcement number CN 213982310 U) disclose the technical scheme of the anti-seismic support of the air pipe, they all lack the structural support in the three-dimensional composite direction, and they need multiple non-standardized structures, which cannot produce prefabricated components in the early production, and have high demand for the standardization of the site construction.

[0004] In the current engineering practice, although some anti-seismic support devices have considered the anti-swing performance in the horizontal plane, there are significant defects in the vertical axial vibration absorption mechanism. Especially when the building structure has longitudinal displacement, the traditional support system lacks effective stress buffering and energy dissipation structure, so that the kinetic energy borne by the pipeline system cannot be effectively attenuated.

[0005] At the level of engineering deepening design, the existing technical system faces multiple challenges: first, the standardized production and on-site assembly of support components have process breakpoints, and non-standard component processing still exists in some construction sites, which makes it difficult to guarantee the prefabrication requirements of finished components specified in GB50981; second, the optimization design of dynamic support spacing lacks systematicness, especially when the pipeline passes through the structure deformation joint, there is a lack of three-dimensional support structure for the pipeline system that meets the specification requirements.

[0006] These technical defects seriously restrict the overall seismic performance of the pipe network system under seismic working conditions, so there is an urgent need to design a rectangular air pipe support that can realize seismic resistance in multiple directions. UTILITY MODEL CONTENT
