Building Wall Intersection Reinforcement for Sound and Seismic Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building wall partition structures with staggered stud arrangements suffer from reduced seismic resistance due to structurally weak points at the intersections, which can lead to cracking during earthquakes, despite improved sound insulation.
Innovation Solution
A reinforcement plate is strategically placed to support the face members at structurally weak corners of the crossing structure, ensuring both sound insulation and seismic resistance by reinforcing the studs at these vulnerable points.

If a one-face structure with staggered studs is used to improve sound insulation, then sound insulation performance is improved, but structural strength at intersection corners deteriorates
Solution Approach 1:
The patent applies different structural configurations at different locations: one-face structure with staggered studs for most of the wall to achieve sound insulation, but two-face structure with studs at both sides at intersection corners to provide structural strength. This local differentiation resolves the contradiction between sound insulation and structural strength.
Solution Approach 2:
The wall structure is segmented into different zones: regular wall sections use the one-face staggered stud configuration for sound insulation, while intersection corner sections use the two-face configuration with studs at both sides for structural strength. This segmentation allows each zone to optimize for its specific function.
2Strength
If face members are attached to both sides of each stud, then structural strength is improved, but sound insulation deteriorates due to sound bridge formation
Solution Approach 1:
The patent applies the two-face structure with face members on both sides of studs only at intersection corners where structural strength is needed, while using the one-face structure elsewhere to maintain sound insulation. This localized application resolves the contradiction between structural strength and sound insulation.
Solution Approach 2:
The wall is segmented into intersection corner regions requiring two-face structure and regular wall regions using one-face structure. This spatial segmentation allows the system to simultaneously achieve both structural strength at critical points and sound insulation in sound-sensitive areas.

AI summary
To provide a crossing structure of a building wall excellent in both sound insulation and seismic resistance. A crossing structure of a building wall 100 includes a crossing 70 in which a first wall 30 and a second wall 60 intersect in a T-shape in a plan view, wherein at a second corner 72 of the crossing 70, a first B stud 20B to which a second face member 10B is attached is not disposed, a second A stud 50A to which a third face member 40A is attached is disposed, and at the second corner 72, a reinforcement plate 80 straddles both an inner face of the second face member 10B and the second A stud 50A, and is fixed to both the second face member 10B and the second A stud 50A.
