The structure for a building wall intersection (100) has an intersection (70) in which a first wall (30) and a second wall (60) intersect in a T-shape when viewed in a planar view. In the second corner (72) of the intersection (70), a first B stud (20B) equipped with a second face material (10B) is not placed, and a second A stud (50A) equipped with a third face material (40A) is placed. In the second corner (72), a reinforcing plate (80) is extended across the inner surface of the second face material (10B) and both sides of the second A stud (50A), and is also fixed to both sides of the second face material (10B) and the second A stud (50A).

Description

Building wall intersection structure The present disclosure relates to the structure of an intersection of building walls. A dry partition wall including a boundary wall is formed by erecting multiple studs (or inter-columns) spaced along the length of a pair of upper and lower runners and installing a surface material, such as gypsum board, on both sides of each stud. Two living rooms, etc., are partitioned by the partition wall. In a double-sided construction structure in which a surface material is installed on both sides of each stud constituting a dry partition wall, a so-called sound bridge is formed, making it easy for sound to spread (leak) from one living room to another, which can result in a partition wall with low sound insulation performance. Therefore, to improve sound insulation performance, a single-sided structure is applied in which adjacent studs are arranged in a zigzag pattern and a surface material is installed on one side of each stud, and an example thereof is proposed in Patent Document 1. The sound-insulating partition wall disclosed in Patent Document 1 is a partition wall formed by fixing wall boards in a double layer through an interposed column and loading sound insulation material into the hollow layer between the wall boards. One side of the inter-column is in contact with one wall board surface, and a gap is left between the other side of the inter-column and the other wall board surface, so the inter-columns are arranged in a zigzag pattern between the wall boards, and sound insulation material is loaded in the gaps between the hollow layer, the inter-columns, and the wall boards.
