Connecting Device for Construction Materials Without Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting methods for construction materials, such as door frames and building skeletons, face challenges in securely connecting these materials at a distance without using fire for welding, while maintaining an immobile state perpendicular to the direction of the interval between them.
Innovation Solution
A connecting device with a locking portion and a coupling portion that moves in the thickness direction to lock with a locking target member, allowing for secure connection of two construction materials without welding, using a coupling fitting to couple the coupling portion to the other construction material, enabling easy and stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional welding methods are used to connect construction materials, then strong connection strength is achieved, but fire safety hazards and complex processing requirements worsen
Solution Approach 1:
The patent replaces the thermal welding process with a mechanical connection system consisting of a connecting member, locking portion, and coupling portion. The locking portion engages with a locking target member through mechanical interlocking, while the coupling portion attaches to the other construction material via coupling fitting, eliminating fire hazards associated with welding.
Solution Approach 2:
The connecting member acts as an intermediary component between two construction materials that are arranged at a distance from each other. It includes a locking portion that connects to one construction material and a coupling portion that connects to the other construction material, enabling secure connection without direct contact or welding between the materials themselves.
2Adaptability or versatility
If construction materials are connected at a distance, then connection flexibility is improved, but connection stability in thickness direction worsens
Solution Approach 1:
The locking portion is designed to be movable in the thickness direction relative to the locking target member during assembly, allowing the connecting member to adapt to positional variations. Once the coupling portion is secured, the locking portion automatically locks into position, providing stability. This dynamic-then-static transition resolves the contradiction between flexibility during installation and stability in use.
3Reliability
If complex connecting structures are used to ensure stability, then connection reliability is improved, but ease of operation worsens
Solution Approach 1:
The connecting member is segmented into functionally independent portions: a locking portion for engaging with the locking target member and a coupling portion for attaching to the other construction material. This segmentation allows each portion to be optimized for its specific function while simplifying the overall assembly process, as each segment can be independently positioned and secured.

AI summary
A connecting device configured to connect two construction materials arranged at a distance therebetween, that is, a door frame, a base member, and a reinforcing member of a wall includes a connecting member including a locking portion capable of being locked with a locking target member arranged at one construction material along a thickness direction perpendicular to a direction of the distance and a coupling portion configured to be moved in the thickness direction and coupled to the other construction material by a drill screw as a coupling fitting are arranged at an end on a side of the one construction material and an end on a side of the other construction material. When the coupling portion is not coupled to the other construction material, the locking portion is movable in the thickness direction with respect to the locking target member.
