Column-Beam Connection Component with Concave Sidewalls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly column-beam connection components in prefabricated construction lack structural stability and are limited to vertical connections, failing to effectively connect horizontal and vertical components simultaneously.
Innovation Solution
The assembly column-beam connection component features a vertically-oriented connecting body with sequentially arranged sidewalls and inward concave portions, along with a horizontally-oriented connecting body, providing enhanced structural strength and stability through precise alignment and embedding of bolt heads, allowing for simultaneous horizontal and vertical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple connector with installation through-holes is used, then the device complexity is reduced, but the structural stability and strength at connection points deteriorates
Solution Approach 1:
The connector is divided into multiple functional segments: the main body, the flange extension, and the embedding structure. Each segment serves a specific purpose - the main body provides connection functionality, the flange extends for additional connection points, and the embedding structure ensures stable integration with the tubular body, thereby resolving the contradiction between simplicity and strength
Solution Approach 2:
The connector's flange is embedded within the tubular body, creating a nested configuration where one component is integrated inside another. This nesting approach enhances the connection strength by creating a secure fit while maintaining a compact overall structure, addressing the contradiction between device complexity and connection strength
2Device complexity
If only vertical connection is implemented, then the device complexity is reduced, but the adaptability to connect both horizontal and vertical components deteriorates
Solution Approach 1:
The connector is designed with multi-functionality to perform both vertical and horizontal connections through a single component. The flange extension provides multiple installation through-holes that can accommodate bolts in different orientations, enabling the connector to serve multiple connection purposes and improving adaptability without significantly increasing device complexity
Solution Approach 2:
The connector design transitions from one-dimensional (vertical only) to two-dimensional functionality by adding the flange extension with installation through-holes positioned to accommodate both vertical and horizontal bolt arrangements. This dimensional expansion enables versatile connection capabilities while maintaining reasonable structural complexity
3Ease of manufacture
If the connector ends are simply embedded in tubular bodies, then the ease of manufacture is improved, but the structural stability at connection points deteriorates
Solution Approach 1:
The flange is pre-formed with installation through-holes and embedding features before final assembly. This preliminary preparation of the connector components ensures that when the flange is embedded in the tubular body, the alignment and stability are already optimized, achieving both ease of manufacture and high connection stability without requiring complex post-processing

AI summary
An assembly column-beam connection component includes a vertically-oriented connecting body for connecting to columns and a horizontally-oriented connecting body for connecting to beams. One end of the horizontally-oriented connecting body is connected to the vertically-oriented connecting body. The vertically-oriented connecting body includes sequentially arranged front sidewall, left sidewall, rear sidewall, and right sidewall. Each of these sidewalls features concave portions extending along the vertically-oriented connecting body's length in the vertical direction. The concave portions on the left sidewall and rear sidewall are positioned near the junction of the left sidewall and rear sidewall, while those on the front sidewall and right sidewall are situated at their respective centers. Multiple installation through-holes for connecting to columns are provided on the various sidewalls of at least one end of the vertically-oriented connecting body.
