Dual Gasket Panel Joint Sealing With Preinstalled Water Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sealing panel-to-panel joints in building construction require extensive exterior work and long cure times, leading to increased costs and safety concerns due to the need for personnel lifts or scaffolding.
Innovation Solution
A dual gasket assembly comprising a support coupling, a compressible interior gasket, and a compressible outer weather gasket, designed for pre-installation on individual panels, which includes a gutter channel for water direction and allows for efficient sealing of abutment joints without post-installation exterior work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wet sealant injection method is used to seal abutment joints, then air and water sealing is achieved, but long cure times and extensive exterior work are required
Solution Approach 1:
The gasket assembly is pre-installed on the panel during panel fabrication before the panel is placed in the wall. This preliminary action eliminates the need for post-installation sealant injection and curing, as the gasket is already in position to receive and seal against the adjacent panel edge.
Solution Approach 2:
The sealing function is extracted from the traditional wet sealant system and implemented through a pre-installed compressible gasket. This removes the harmful element of long cure times and extensive exterior sealant injection work while maintaining the air and water sealing function.
2Reliability
If traditional sealant injection from exterior is used, then joint sealing is achieved, but significant cost for personnel lifts or scaffolding is incurred
Solution Approach 1:
The gasket is pre-installed on the panel at the manufacturing stage, transferring the sealing preparation work from the expensive post-installation exterior phase to the controlled manufacturing environment. This eliminates the need for personnel lifts or scaffolding during construction.
Solution Approach 2:
The pre-installed gasket acts as an intermediary that receives the adjacent panel edge and provides sealing without requiring exterior sealant injection. This intermediary mechanism eliminates the need for expensive exterior access equipment while achieving reliable joint sealing.
3Reliability
If traditional exterior sealant application is used, then abutment joint sealing is achieved, but safety concerns increase due to work at height
Solution Approach 1:
The gasket installation is performed as a preliminary action during panel manufacturing in a safe, controlled environment. This eliminates the need for workers to perform sealant injection operations at height on completed walls, thereby eliminating the associated safety hazards.
Solution Approach 2:
The hazardous exterior sealant application operation is extracted and replaced by the pre-installed gasket system. The sealing function remains, but the dangerous exterior work at height is completely removed from the construction process.
