Solution Overview
Problem
Existing methods for producing prefabricated components, such as double-walled panels, face challenges including complex and imprecise base plate production, water penetration through construction joints, and labor-intensive site alignment and assembly, leading to high construction costs and inefficiencies.
Innovation Solution
The method involves machining mating sections under controlled workshop conditions using laser measurements and computer-controlled tools to achieve precise fitments, allowing components to be assembled with tight tolerances and secured with screws, eliminating the need for on-site individual setup and reducing assembly efforts by using adjustable built-in parts and hardening plastic mass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If base plates are produced using traditional methods at the construction site, then flexibility in assembly is maintained, but manufacturing precision and alignment accuracy deteriorate
Solution Approach 1:
The base plates are pre-produced with integrated mounting parts in a controlled workshop environment before delivery to the construction site. This preliminary action allows precise machining and quality control to be performed under optimal conditions, eliminating the need for complex on-site production operations while ensuring high manufacturing precision.
2Productivity
If components are assembled with individual setup and support at the construction site, then adaptability to site conditions is maintained, but assembly time and labor costs increase
Solution Approach 1:
Mounting parts are pre-installed on the components during workshop production, and mating sections are pre-machined to precise tolerances. This preliminary preparation eliminates the need for time-consuming individual setup and support operations at the construction site, allowing components to be quickly assembled by simply connecting the pre-prepared mating sections.
3Reliability
If construction joints are used between floor slab and wall slab, then structural flexibility is maintained, but water tightness and sealing quality deteriorate
Solution Approach 1:
The mounting parts are integrated directly into the base plates during workshop production, merging what would traditionally be separate components (base plate and mounting hardware). This integration eliminates construction joints between floor and wall slabs, providing inherent water tightness while reducing the complexity of sealing details.
4Manufacturing precision
If mating sections are machined under controlled workshop conditions, then manufacturing precision is improved, but production process complexity increases
Solution Approach 1:
All mating sections are machined to precise tolerances during the initial workshop production phase while components are being manufactured. This preliminary machining action takes advantage of the controlled workshop environment and fixed positioning, achieving high precision that would be difficult to obtain on-site, while the standardized processes keep production manageable.

AI summary
The invention relates to a method for producing prefabricated structural parts (5, 14) from a setting plastic compound for erecting buildings, in which the setting compound is filled into a shuttering and left to set into panels, two panels (12, 13) being joined together if necessary by means of reinforcements placed into the shutterings to form a double-walled panel (14). The built-in parts (3, 4, 20, 20'), which serve for the adjustable support of the prefabricated structural parts and/or for joining them to one another, are attached to the edge regions of the panels or double-walled panels, wherein the built-in parts (3, 11, 11', 20, 20') have fitting portions (8, 10, 21, 23), which serve as adjusting and joining points with respect to neighbouring panels or double-walled panels. In a further method step, the fitting portions are worked at positions that are fixed with respect to the panels or double-walled panels, in order to compensate for deviations in the position of the fitting portions from the intended dimensions of the panels or double-walled panels. The invention also relates to prefabricated structural parts produced by the method.
