Description

Integrated assembly support for medium pressure vertical pipeline

technical field

The invention relates to a support, in particular to an integrated assembled support for medium-pressure bearing vertical pipelines.

Background technique

The guide bracket is used to ensure the displacement of the pipeline in a certain direction and limit the displacement in other directions. The vertical pipe guide bracket is used to ensure that the water pipe moves in the axial direction under the condition of thermal expansion and cold contraction, so as to avoid damage to the pipe caused by the lateral movement of the pipeline. According to the design requirements, it is necessary to set up a guide bracket on each floor to meet the use requirements.

The load-bearing bracket is a support and hanger used to bear the gravity of the pipeline and other vertical downward loads. The load-bearing bracket needs to meet the following points: 1) The distance between the load-bearing bracket should not be greater than the maximum distance between the pipelines. Generally, the maximum distance between the pipelines is based on the strength Conditions and stiffness conditions are determined by calculation, and the minimum value is taken. If there is a pipeline with pressure pulsation, the distance of the load-bearing support should be determined according to the required natural frequency of the pipeline to avoid resonance; 2) Try to use the existing civil structure components to support , that is, supported on the beams and columns of the pipe gallery; 3) For the pipes undergoing flexibility analysis, the position of the load-bearing bracket is determined according to the analysis, and the possibility of support is considered; 4) The position and type of the load-bearing bracket should minimize the impact of the force on the rooted adverse effects on components.
