Securing Member With Bulging Portions For Wall Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional securing members for wall materials in building frames face challenges in withstanding large loads during earthquakes or strong winds, leading to potential deformation and instability.
Innovation Solution
A securing member with a substrate portion, bulging portions, locking portions, and end-side fixing portions, where the inner-side contact surface is wider than the end-side contact surface, dispersing loads and enhancing strength to prevent deformation, and featuring a central fixing portion for load distribution and uneven surfaces for improved attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional securing members are used, then basic wall material fixation is achieved, but the securing member deforms under large loads during earthquakes or strong winds
Solution Approach 1:
The patent applies local quality by creating a bulging portion with different geometric properties at different locations. The inner-side bulging portion has a larger width than the end-side bulging portion, providing localized reinforcement where the wall material contacts the securing member. This non-uniform geometry concentrates strength where needed to prevent deformation under large loads while maintaining overall structural integrity.
Solution Approach 2:
The patent transitions from a conventional two-dimensional flat securing member to a three-dimensional structure with bulging portions that extend in the width direction. This dimensional change creates additional contact surfaces and structural volume, enabling the securing member to withstand larger loads by distributing stresses across multiple spatial dimensions rather than relying solely on planar geometry.
2Ease of manufacture
If the securing member structure is simplified, then manufacturing is easier, but the strength and stability under large loads are insufficient
Solution Approach 1:
The patent segments the securing member into distinct functional portions: a substrate portion, a bulging portion with inner-side and end-side sections, and a locking portion. This segmentation allows each part to be optimized independently for its specific function while maintaining overall structural strength. The modular design facilitates manufacturing by enabling focused production of each segment with appropriate geometric characteristics.

AI summary
Provided are a wall structure that has high strength and can stably support a wall material, and a securing member that is used in the wall structure. The wall structure includes a securing member 10 that fixes a wall material 2 to a building frame 8. The securing member 10 includes a substrate portion 15, a bulging portion 30 that bulges from the substrate portion 15 and extends in a left-right direction, a contact surface 31 that comes into contact with the rear surface of the wall material 2, and a locking portion 13 that engages the wall material 2. The bulging portion 30 has bulging portions 30E and 30F, the substrate portion 15 includes an end-side fixing portion 17 on an end side in the left-right direction, the end-side fixing portion 17 is surrounded in the left-right direction and on the lower side by the bulging portions 30, 30E, and 30F, and the inner-side bulging portion 30F adjacent on the inner side to the end-side fixing portion 17 of the bulging portions 30E and 30F is inclined such that the width in the left-right direction increases toward the locking portion 13. In the securing member 10, the end-side fixing portion 17 on one end side is fixed to the building frame 8, and the end-side fixing portion 17 on the other end side supports the wall material 2 using the locking portion 13 in a state of not being fixed.
