Adjustable Riser Support Assembly for Continuous Floor Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riser support assemblies, such as riser clamps, are difficult to adjust once installed and struggle to maintain a desired gap between risers due to weight and expansion/contraction of piping systems, leading to disengagement from the floor during pressurization.
Innovation Solution
A riser support assembly with adjustable mounts that can engage a mounting surface and selectively adjust its height, allowing for adjustment during installation and to accommodate expansion/contraction of the piping system, ensuring continuous support by transferring the load to the surrounding structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a riser clamp is used to support the riser stack, then the load can be transferred to the floor, but the clamp disengages from the floor upon expansion or compression of the piping system and is difficult to adjust once installed
Solution Approach 1:
The riser support assembly incorporates an adjustable mechanism that allows the support height to be dynamically modified. The mount includes an adjustable arm with multiple positioning holes that enable the support height to be changed to accommodate piping expansion and contraction, while maintaining continuous engagement with the floor surface.
Solution Approach 2:
The invention changes the geometric parameter of the support assembly by providing multiple adjustable height positions through the array of positioning holes in the adjustable arm. This allows the support height to be varied within a range to compensate for thermal expansion and contraction of the piping system.
2Reliability
If a riser clamp is used to support the riser stack, then the load can be transferred to the floor, but the clamp is difficult to adjust once installed
Solution Approach 1:
The riser support assembly is divided into separate components including a clamp portion, an adjustable arm, and a mount base. This segmentation allows for easier installation and adjustment, as each component can be independently positioned and secured without requiring complex assembly procedures.
Solution Approach 2:
The adjustable arm provides dynamic adjustment capability during installation, allowing the support height to be modified to achieve proper alignment and engagement with the floor, thereby simplifying the installation process while ensuring reliable load transfer.
3Productivity
If the piping system is pressurized with fluid, then the system can operate, but expansion or compression occurs causing disengagement from the floor
Solution Approach 1:
The adjustable arm with multiple positioning holes enables the support height parameter to be changed in response to piping expansion and contraction caused by pressurization. This maintains the desired gap between risers and ensures continuous floor engagement throughout system operation.
Solution Approach 2:
The dynamic adjustment capability of the mount allows it to adapt to the changing dimensions of the piping system during operation, maintaining stable support and proper gap spacing despite thermal expansion and contraction cycles.
4Force
If the weight of the riser stack is considered, then the load can be transferred to the floor, but it becomes difficult to set a desired gap between risers
Solution Approach 1:
The adjustable arm provides dynamic height adjustment capability that allows precise gap setting between risers. The multiple positioning holes enable fine-tuning of the support height to achieve the desired gap precision, while the robust clamp mechanism maintains the full weight load.
