Masonry Reinforcement with Integrated Deformed Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Masonry structures are vulnerable to lateral loads during earthquakes, leading to out-of-plane deformation and potential collapse due to lack of integrity, and existing reinforcement methods complicate the construction process with increased parts and longer installation times.
Innovation Solution
A method involving deformed bars tied to the entire circumference of the masonry structure at predetermined heights, using cross joints and deformed bar fixtures with spiral wing angles and grooves, along with silicon and non-shrink mortar for impact absorption and crack repair, simplifying the construction process and enabling integral movement with the wall during earthquakes.

Engineering Contradiction Analysis
1Reliability
If multiple parts (deformed bars, fixing members, additional deformed bars, fixtures) are used to reinforce the masonry wall, then the anti-seismic performance and integrity of the wall are improved, but the construction process becomes more complex and installation time increases
Solution Approach 1:
The patent combines multiple reinforcement components into a single integrated deformed bar assembly. The deformed bar is configured with horizontal segments positioned at different heights and vertical segments connecting them, forming a unified structure that provides both horizontal and vertical reinforcement. This merging of multiple parts into one component simplifies the construction process while maintaining anti-seismic performance.
Solution Approach 2:
The deformed bar serves multiple functions simultaneously: it provides horizontal reinforcement, vertical reinforcement, and connects different levels of the masonry wall. The single component performs the roles of multiple separate elements (horizontal deformed bars, vertical deformed bars, and fixing members) that would otherwise be required, thereby reducing construction complexity while ensuring structural integrity.
2Stability of the object's composition
If multiple separate reinforcement components are installed, then the structural integrity is improved, but the installation time and construction duration are increased
Solution Approach 1:
By integrating horizontal and vertical reinforcement functions into a single deformed bar component, the patent reduces the number of separate installation operations. The unified structure can be installed as one piece, significantly reducing the time required compared to installing multiple separate components sequentially, while maintaining comprehensive structural integrity.
Solution Approach 2:
The deformed bar is pre-configured with the complete reinforcement pattern including horizontal segments at different heights and vertical connecting segments. This preliminary preparation of the reinforcement structure allows for rapid installation without requiring on-site assembly of multiple parts, thereby reducing installation time while ensuring proper structural integrity from the outset.

AI summary
An anti-seismic performance reinforcement structure of a masonry structure and a construction method of the same are proposed, where a deformed bar is constructed to be tied to the entire circumference of the masonry structure at every predetermined height thereof such that the masonry structure is connected to a wall, thereby simplifying a construction process, and inducing the masonry structure and the wall to be moved integrally to each other during an earthquake so as to prevent the masonry wall from collapsing. The method of performing anti-seismic performance reinforcement and crack repair of the masonry structure includes: removing a predetermined depth of a horizontal joint; mounting the cross joint by forcibly press-fitting the cross joint having the press-in holder and the horizontal holder to a perforated position; fixing a deformed bar fixture to the wall; and tying the entire circumference of the masonry structure with the deformed bar.
