Bracket Assembly for Roof-to-Wall Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting roof structures to wall partitions in buildings are inadequate in providing structural integrity during extreme events, as they often involve ineffective fastening methods that can cause structural weakness and allow for excessive movement, posing risks during seismic events or external forces.
Innovation Solution
A bracket assembly comprising overhead fixing members, a bracket member, a bearing member, and a sleeve member, interconnected with fasteners, which connects the roof structure to the wall without directly loading on the ceiling, providing structural integrity between the roof and wall structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fasteners like nails or bolts are used to connect roof structure to wall partition, then connection is achieved, but the fastening is awkward and not effective in providing good positive fastening
Solution Approach 1:
The connection system is divided into separate components: a bracket member with bearing surface, a separate fastening mechanism, and positioning elements. This segmentation allows each component to perform its specific function optimally - the bracket provides bearing support while the fastening mechanism provides secure attachment, resolving the contradiction between reliable connection and ease of installation.
Solution Approach 2:
The bracket member acts as an intermediary element between the roof structure and wall partition. It provides a bearing surface that distributes loads and facilitates proper positioning, making the connection process easier while maintaining high reliability through its intermediate bearing function.
2Adaptability or versatility
If existing bracing structures are cut to attach to walls and roof structures for different angles or distances, then adaptability is improved, but structural weakness is caused to the bracing structure
Solution Approach 1:
The bracket member is designed with adjustable positioning capabilities that allow adaptation to different angles and distances without modifying the bracing structure. The dynamic adjustability is achieved through repositionable fastening points and adjustable mounting configurations, maintaining bracing structure integrity while providing connection versatility.
Solution Approach 2:
The bracket member incorporates localized bearing surfaces and fastening points that can be positioned at different locations to accommodate various connection requirements. This local adaptability allows the bracket to adjust to different angles and distances without compromising the overall bracing structure strength.
3Reliability
If ceiling structures are used to connect roof to wall, then connection is provided, but the ceiling is not held rigidly and can sway or move very easily
Solution Approach 1:
The invention extracts the ceiling structure from the load-bearing connection function. The bracket member with its bearing surface provides the rigid connection between roof and wall, while the ceiling is taken out of this structural role and can remain as a non-structural element, eliminating the contradiction between connection reliability and ceiling stability.
Solution Approach 2:
The bracket member serves as an intermediary that provides rigid structural connection independently of the ceiling. By introducing this intermediate bearing structure, the ceiling is relieved of structural demands and can remain stable while the bracket ensures reliable roof-to-wall connection.
4Ease of operation
If fasteners are attached through ceiling or roof structure to top of wall partition, then connection is achieved, but structural integrity is compromised during extreme events
Solution Approach 1:
The bracket member is pre-positioned and secured to provide structural support before final fastening. The bearing surface is established in advance, allowing loads to be properly distributed from the beginning of the connection process, thereby maintaining structural integrity while keeping installation simple.
Solution Approach 2:
The bracket member with its bearing surface provides beforehand cushioning and load distribution capability. This preliminary structural support ensures that during extreme events, the connection maintains integrity by distributing forces through the bearing surface rather than concentrating them at fastener points.

AI summary
A bracket assembly for connecting an overhead roof structure to below roof structure elements of a building. The below roof structure elements include a wall having a top plate member or ceiling support structure. The bracket assembly includes overhead fixing members, a bracket member, bearing member, sleeve member, and below roof structure fastener, which are interconnected and fastened together. One end of the bracket member is connectable to the overhead fixing members to the overhead roof structure and the other end is connectable to the below roof structure fastener which is connectable to the below roof structure. The bearing and sleeve members are located and connected between the bracket member and the below roof structure such that the bracket member rests without loading on the bearing member which then rests on the sleeve member which when used rests without loading on the below roof structure, providing structural integrity.
