H-Shaped Insulation Mold for Precast Concrete Wall Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pre-cast concrete wall systems face challenges in forming molds solely with self-supporting insulation, meeting building codes for R-Value and thermal requirements, accommodating interior finish materials, especially in corners, and forming 90-degree corners without additional structural support.
Innovation Solution
The use of H-shaped insulation pieces that create cavities for concrete studs and furring strips, allowing for the formation of pre-cast concrete walls with integrated insulation that meets building codes and enables secure fastening of finish materials, along with a method of constructing prefabricated wall structures using these insulation pieces and framing means to create a self-supporting mold system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional metal channels and formwork are used to hold insulation in place, then the insulation can be securely positioned, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes traditional metal channels and formwork from the mold structure, retaining only the essential insulation pieces and concrete elements. The insulation pieces are specifically cut and shaped to be self-supporting, eliminating the need for metal support structures while maintaining positioning stability.
Solution Approach 2:
The insulation pieces are designed to be self-supporting through specific cutting and shaping, allowing them to maintain their position without external metal support structures. The concrete elements themselves provide the necessary support and positioning for the insulation pieces during the pouring process.
2Manufacturing precision
If insulation pieces are specifically cut to size and shape to form self-supporting molds, then the manufacturing precision and thermal performance improve, but the manufacturing complexity increases
Solution Approach 1:
The mold is divided into separate, specifically cut insulation pieces that can be manufactured independently and then assembled. Each piece is cut to precise dimensions and shapes required for its specific position in the mold, allowing for modular manufacturing and assembly.
Solution Approach 2:
The insulation pieces are pre-cut to their final size and shape before assembly into the mold structure. This preliminary preparation ensures precise dimensions and fits, allowing the pieces to be self-supporting and properly positioned without requiring complex adjustment mechanisms during assembly.
3Strength
If additional structural elements are added to corners to support finish materials, then the structural integrity improves, but the device complexity and construction time increase
Solution Approach 1:
The patent combines the corner structural elements with the insulation pieces and concrete wall panels themselves. The insulation pieces are specifically shaped to form corners, and the concrete elements are integrated to provide both structural support and finishing surfaces, eliminating the need for separate corner support structures.
Solution Approach 2:
The corner elements serve multiple functions simultaneously: they provide structural support for the wall, maintain thermal insulation continuity, and provide a finished surface for attaching wallboard. This multi-functionality eliminates the need for additional specialized corner components.
4Productivity
If pre-cast wall panels are used instead of poured-in-place walls, then the construction speed and precision improve, but the mold design complexity and initial manufacturing cost increase
Solution Approach 1:
The patent uses insulation pieces that can be easily manufactured, assembled into molds, used for casting concrete panels, and then removed or reused. The simplicity of the mold components allows for quick assembly and disassembly, enabling rapid production of pre-cast panels despite the specialized nature of the mold design.

AI summary
A method of constructing a prefabricated wall structure comprising orienting interspaced stud molds having an H-shaped channel shape cross sections and edges defining an open portion of the channel shape, in a horizontal configuration within a framing means having a top, bottom, and sides and providing containing walls of the mold such that the edges of the molds form uppermost parts of the stud molds and are located within an essentially horizontal plane within the framing means; the stud molds being spaced equally between the top and bottom framing means to thereby create a space above and below, wherein the stud molds and framing means create cavities that are in fluid communication with one another; positioning rigid insulation panels within the framing means, to form a continuous surface within the framing means; pouring concrete into the enclosed forms so as to cover the rigid insulation panels and to fill the stud molds thereby forming the prefabricated wall structure, permitting the poured concrete to set; and removing the wall structure.
