Shear Wall Tie Bar Structure for Reduced Mesh Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shear wall construction requires a large number of tie bars for secure connection, increasing labor and costs.
Innovation Solution
A tie bar design with a first end portion and a second end portion, featuring inverted U-shaped sections and hooks, is used to connect opposing steel meshes in a shear wall, reducing the number of tie bars required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tie bars with hooks at each end are used to connect opposing steel meshes, then secure connection is achieved, but the number of tie bars required increases significantly
Solution Approach 1:
The patent merges the function of multiple conventional tie bars into a single improved tie bar by adding transverse connections that link the first and second end portions. This allows one tie bar to secure multiple vertical bars from both steel meshes simultaneously, reducing the total number of tie bars needed while maintaining connection security
Solution Approach 2:
The tie bar is segmented into distinct functional portions: a first end portion with a hook for connecting to vertical bars of the first steel mesh, a second end portion with hooks for connecting to vertical bars of the second steel mesh, and transverse connections linking these portions. This segmentation allows each portion to perform its specific function efficiently
2Strength
If a large number of conventional tie bars are used to secure opposing steel meshes, then structural integrity is maintained, but labor and construction costs increase
Solution Approach 1:
By combining multiple connection functions into a single tie bar through the addition of transverse connections, the invention reduces the total number of tie bars required, thereby decreasing labor input and construction time while maintaining the same level of structural integrity
Solution Approach 2:
The improved tie bar performs multiple functions: it connects vertical bars from the first steel mesh, connects vertical bars from the second steel mesh, and links these connections together through transverse connections. This multi-functionality allows fewer tie bars to achieve the same structural reinforcement effect

AI summary
A tie bar for fixing opposing steel meshes in a shear wall is provided. The shear wall includes a first steel mesh and a second steel mesh. The first steel mesh and the second steel mesh are spaced apart by a predetermined distance. The tie bar includes a first end portion, a second end portion, and two connections. The first end portion is configured to surround and be fixed to two adjacent vertical bars of the first steel mesh. The second end portion includes two free ends, and these two free ends are configured to respectively be fixed to two adjacent vertical bars of the second steel mesh. The two connections connect the first end portion and the second end portion respectively.
