Is the design predetermined or is it calculated by the construction party itself?
The offset of the sliding bracket needs to be determined based on specific circumstances. Generally, during the design phase, parameters such as the installation position and offset of the sliding support are determined based on the project requirements and actual conditions. During the construction process, the contractor must carry out work in strict accordance with the design requirements, and ensure that the deviations are correct through measurement and inspection. If parameters such as the offset are not specified during the design phase, the construction party must carry out calculations based on the actual conditions, and ensure that the installation of the sliding brackets and their offsets meet safety requirements. .
Some are produced by design institutes and are very detailed
The design is given. There was once a project in which the owner checked for interference between the reinforcement bars of the sliding supports and the sliding limit plates on the structural supports; in other words, the position of those limit plates wasn’t considered properly, and as the pipelines expanded due to heat, they would go beyond the position of those limit plates. The contractor shall construct in accordance with the drawings, and the design party must review and confirm whether the thermal expansion displacement is sufficient.
