Building Exterior Panel Joint Sealing via Insulation Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exterior insulation materials for buildings, such as sandwich panels and metal panels, often experience dew condensation and water leakage due to weak joints, which compromise thermal insulation and structural integrity.
Innovation Solution
Incorporating an insulation member with an adhesive and insulation portions, including polyvinyl chloride foam, between the rear steel plate and the upper and lower frames, and using gaskets and drains to enhance sealing and prevent water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional sandwich panels and metal panels are used for building exteriors, then construction is simplified and lightweight materials are utilized, but dew condensation and water leakage occur at joints compromising thermal insulation
Solution Approach 1:
The patent introduces a sealant member as an intermediary component between the rear steel plate and the building structure. This sealant member specifically addresses the joint sealing problem by filling and sealing the joint space, preventing dew condensation and water leakage while maintaining the overall panel structure's ease of construction.
Solution Approach 2:
The patent employs composite material construction with a rear steel plate, insulation material, and sealant member working together. The sealant member is positioned at the joint between the rear steel plate and the building structure, creating a composite system that combines structural integrity with enhanced sealing performance to prevent moisture ingress.
2Productivity
If joints are used to connect panels during construction, then assembly is facilitated, but thermal insulation performance deteriorates due to dew condensation and water leakage
Solution Approach 1:
The sealant member serves as a mediator in the joint region, maintaining the assembly efficiency of the panel system while compensating for the thermal insulation deficiency at joints. By sealing the joint space, it prevents dew condensation and water leakage that would otherwise compromise thermal performance.
Solution Approach 2:
The patent applies local quality enhancement by specifically addressing the joint region with a sealant member. While the overall panel structure maintains its simple assembly design, the localized application of sealing material at critical joint areas prevents thermal loss through dew condensation and water infiltration.
3Loss of energy
If the rear steel plate is spaced apart from the building structure, then thermal insulation is improved, but structural stability may be compromised
Solution Approach 1:
The sealant member acts as an intermediary between the rear steel plate and the building structure, allowing the rear steel plate to be spaced apart for thermal insulation while still providing structural connection. The sealant member fills the gap and provides both sealing and structural bonding functions.
Solution Approach 2:
The patent creates a composite connection system where the sealant member bonds the rear steel plate to the building structure. This composite approach allows the spacing needed for thermal insulation while maintaining structural stability through the adhesive properties of the sealant material.
