Bolted Filling Element Assembly for Building Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional welding methods for connecting filling elements to skeletal structures in building assemblies are laborious, require skilled craftsmen, and can cause damage and corrosion, while also necessitating heavy hoisting equipment for suspension during assembly.
Innovation Solution
A bolted connection system replaces welding, allowing for quick assembly by any worker, eliminating the need for skilled craftsmen and reducing the requirement for heavy hoisting equipment, with a structurally integrated I-shaped beam and plate configuration that distributes load effectively and prevents overconstraint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding operations are used to connect filling elements to the skeletal structure, then a strong connection is achieved, but the assembly process becomes laborious and time-consuming
Solution Approach 1:
The patent replaces the welding process (thermal/chemical system) with a bolted mechanical connection system. The filling element includes a connector with a hole that receives a bolt, allowing mechanical fastening instead of welding. This substitution maintains connection strength while dramatically improving assembly speed and eliminating the need for skilled welders.
2Reliability
If welding operations are used to connect filling elements, then connection is achieved, but skilled craftsmen are required
Solution Approach 1:
The welding process is replaced with a bolted connection system that can be assembled by unskilled workers. The connector is designed with a simple hole that receives a bolt, eliminating the need for specialized welding skills while maintaining reliable structural connection.
Solution Approach 2:
The filling element's connector is designed to be self-aligning and self-contained, with the hole positioned to automatically receive the bolt. This simplifies the assembly process further, allowing workers to perform the connection without specialized training or complex procedures.
3Reliability
If welding operations are used, then connection is achieved, but sparks cause damage and corrosion
Solution Approach 1:
The welding process that generates harmful sparks is replaced with a cold mechanical bolted connection. This eliminates the thermal and chemical effects of welding that cause sparks, corrosion, and potential damage to surrounding building materials while maintaining secure structural connection.
4Reliability
If welding operations are used, then connection is achieved, but dark spots and quality perception issues arise
Solution Approach 1:
The welding process that leaves unsightly dark spots and affects aesthetic quality is replaced with a bolted connection system. The connector can be designed and finished to match the surrounding architecture, eliminating the permanent visual defects caused by welding sparks and heat exposure.
5Strength
If filling elements are connected using traditional methods, then structural connection is achieved, but heavy hoisting equipment is required
Solution Approach 1:
The connector is pre-integrated into the filling element during manufacturing, with the hole and bolt arrangement predetermined. This preliminary preparation allows the filling element to be quickly connected to the skeletal structure without requiring heavy hoisting equipment to maintain suspension during complex assembly operations.
