Permanent Modular Formwork Panels for Integrated Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional construction methods require the removal of temporary wooden formwork after concrete pouring, which prolongs work time, wastes materials, and increases costs, and additional sealing layers are necessary for waterproofing.
Innovation Solution
Employing modular polymer panels that remain as a permanent part of the structure, eliminating the need for formwork removal and providing integrated waterproofing and insulation, with a locking mechanism for secure panel connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temporary wooden formwork is used for concrete pouring, then the formwork can be removed and reused, but this requires significant time and labor for removal and additional sealing layers are needed
Solution Approach 1:
The patent combines the formwork function with the waterproofing function into a single integrated system. The interlocking panels create both the concrete form and the waterproof barrier simultaneously, eliminating the need for separate sealing layers and reducing construction steps.
Solution Approach 2:
The waterproofing and insulation layers are pre-integrated into the panel structure itself. The panels come with built-in vapor barriers and insulation materials already attached, so no additional sealing or insulation work is needed after concrete pouring.
2Ease of manufacture
If temporary wooden formwork is used, then materials can be reused, but the removal process is time-consuming and labor-intensive
Solution Approach 1:
The panels are designed to remain in place and serve the building permanently as waterproofing and insulation layers. This eliminates the need for removal and reinstallation, allowing the system to serve its own purpose continuously without requiring labor-intensive拆卸 and reassembly operations.
3Reliability
If additional sealing layers are added for waterproofing, then waterproofing performance is improved, but this increases material usage and construction complexity
Solution Approach 1:
The formwork and waterproofing functions are merged into a single integrated panel system. The interlocking panels with built-in vapor barriers provide both structural formwork and waterproofing in one system, eliminating the need for separate sealing layers and reducing overall construction complexity.

AI summary
A modular wall is a permanent external frame solution for a building. It includes outer panels and inner panels each made of high impact thermoplastic polymer, eliminates the need for removable formwork, reduces construction time and improves insulation and waterproofing. The panels join together in a locking connection by snapping or sliding an end of a first panel to an opposite end of an adjacent second panel. Reinforcing metal pipes connecting each outer panel to a corresponding inner panel occupy a negligible amount of space where the concrete is to be poured so as not to obstruct rebar. Quality control is enhanced since the panels may be transparent to monitor the concrete casting. Each of the outer panels and inner panels may include two substantially parallel walls separated by a pattern of reinforcing ribs that together with the substantially parallel walls define spaces for heat insulation and increase structural integrity.
