Beam Frame Joint Device for Reduced Assembly Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional joint devices for beam frame assemblies require numerous components and complex assembly processes, leading to low construction efficiency due to the need for multiple fasteners and holes, increasing the time and complexity of assembling longitudinal and transverse beams.
Innovation Solution
A joint device comprising a main fixing plate with vertical and extending walls, an auxiliary fixing plate, and a fastener that securely connects longitudinal and transverse beams with fewer components, reducing the number of holes required and simplifying the assembly process by using a screw and nut configuration that allows for stable clamping without the need for multiple fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional joint device with multiple fasteners and plates is used, then connection stability is improved, but device complexity and assembly time increase
Solution Approach 1:
The patent combines multiple separate fastening components (front fixing plate, rear fixing plate, auxiliary fixing plate, and multiple fasteners) into a single integrated joint device. The joint device includes a body with first and second clamping portions that can simultaneously clamp both the longitudinal beam and transverse beam, eliminating the need for multiple separate plates and fasteners while maintaining connection stability.
Solution Approach 2:
The joint device is designed as a multi-functional component that performs multiple functions: it clamps the longitudinal beam through the first clamping portion, clamps the transverse beam through the second clamping portion, and provides a unified fastening structure. This single device replaces what previously required multiple specialized components, reducing overall device complexity while maintaining all necessary connection functions.
2Reliability
If multiple through holes are provided in beams for multiple fasteners, then connection reliability is improved, but assembly time and construction efficiency deteriorate
Solution Approach 1:
The joint device consolidates multiple fastening functions into a single integrated structure with unified fastening holes. Instead of requiring separate holes for the front fixing plate, rear fixing plate, and auxiliary fixing plate, the joint device body contains integrated first and second clamping portions that can be fastened through consolidated hole arrangements, reducing the total number of holes needed and simplifying the drilling and assembly process.
3Strength
If numerous components are used to clamp beams, then connection strength is improved, but assembly process complexity increases
Solution Approach 1:
The patent integrates multiple clamping functions into a single joint device body that contains both the first clamping portion for the longitudinal beam and the second clamping portion for the transverse beam. This unified structure maintains the connection strength provided by multiple clamping surfaces while eliminating the need to assemble multiple separate plates and fasteners, thereby simplifying the assembly process.
Solution Approach 2:
Within the unified joint device body, the clamping functions are segmented into distinct first and second clamping portions, each optimized for clamping specific beams. This internal segmentation allows the single device to provide multiple clamping actions with appropriate force distribution, maintaining connection strength while presenting a simplified external assembly interface.

AI summary
A joint device includes a main fixing plate, an auxiliary fixing plate, and a fastener. The main fixing plate has a vertical wall disposed between a longitudinal beam and a transverse beam, a first extending wall extending towards a side of the longitudinal beam from the vertical wall and crossing over and abutting against an upper portion of the longitudinal beam, and a second extending wall extending towards a side of the transverse beam from the vertical wall and crossing over and abutting against a lower portion of the transverse beam. The auxiliary fixing plate is disposed in an open groove of the transverse beam in a way that the transverse beam is clamped between the auxiliary fixing plate and the vertical wall of the main fixing plate. The fastener secures the longitudinal beam, the transverse beam, the main fixing plate and the auxiliary fixing plate together.
