Foldable Column Frame Structure for Prefabricated House
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional prefabricated houses face challenges in efficient transportation and appearance due to protruded eaves portions and gutters, which compromise waterproof performance and aesthetic appeal, especially in high-quality building applications.
Innovation Solution
A column frame structure with a foldable design that prevents the roof panel's eaves portion from protruding beyond the column frame, incorporating an eaves gutter that extends downward and is integrated with a concave top plate and swinging gable beam, allowing for efficient assembly and storage while maintaining waterproof performance and a unified appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the eaves portion of the roof panel is extended outward for waterproof performance, then the waterproof performance is improved, but the eaves portion becomes an obstacle at the time of stacking and transportation
Solution Approach 1:
The eaves gutter is divided into multiple sections that can be folded along with the roof panel. The gutter is segmented into a first section attached to the roof panel and a second section that can be folded downward, allowing the waterproof function to be maintained while enabling compact stacking during transportation.
Solution Approach 2:
The eaves gutter is designed with foldable sections that can dynamically change position. During transportation, the gutter is folded downward to reduce protrusion; during installation, it is extended outward to provide waterproof protection. This dynamic adjustment resolves the contradiction between waterproof performance and stacking efficiency.
2Reliability
If the eaves gutter is fitted to the greatly protruded eaves portion, then the waterproof performance is improved, but the eaves gutter becomes extremely prominent and problematic in terms of appearance
Solution Approach 1:
The eaves gutter is designed with different sections having different functions and positions. The first section provides waterproof protection where needed, while the second section is folded downward to be less prominent. This local differentiation allows the gutter to maintain waterproof performance in critical areas while achieving a more aesthetically pleasing appearance in visible areas.
3Shape
If the eaves portion and eaves gutter are provided so as not to be protruded for satisfactory appearance, then the appearance quality is improved, but the waterproof performance of the eaves gutter is degraded
Solution Approach 1:
The eaves gutter is designed with foldable sections that can dynamically change position. During transportation, the gutter is folded downward to reduce protrusion; during installation, it is extended outward to provide waterproof protection. This dynamic adjustment resolves the contradiction between waterproof performance and stacking efficiency.
4Productivity
If the column frame is designed with foldable structure for efficient transportation, then the transportation efficiency is improved, but the structural complexity increases
Solution Approach 1:
The column frame is divided into multiple sections that can be folded relative to each other. The frame includes upper and lower columns with folding sections that can be collapsed during transportation and expanded during assembly. This segmentation enables compact transportation while maintaining structural integrity through standardized connection mechanisms.

AI summary
An object is to provide a column frame structure for a prefabricated house which enhances the efficiency of transportation, which maintains waterproof performance, and which achieve a satisfactory appearance in terms of appearance.A column frame 20 is foldably fitted onto a floor panel 40. A prefabricated house P in which a roof panel 10 is stacked on the column frame 20 is provided. When the prefabricated house is assembled, a gable end portion in the roof panel 10 is formed so as to be prevented from being protruded beyond the outside surface of the column frame 20. An eaves gutter 50 is installed so as to extend downward from the gable end portion in the roof panel 10. The eaves gutter 50 is formed so as to be prevented from being protruded outward beyond the outside surface of the column frame 20 on the gable.
