WOODEN BUILDING LOAD-BEARING WALL STRUCTURE AND LOAD-BEARING WALL CONSTRUCTION METHOD

Title:

WOODEN BUILDING LOAD-BEARING WALL STRUCTURE AND LOAD-BEARING WALL CONSTRUCTION METHOD

Document Type and Number:

WIPO Patent Application WO/2019/203148

Kind Code:

A1

Abstract:

The purpose of the present invention is to reliably prevent occurrences of punching shear in wooden structure load-bearing walls and to improve the wall strength factor of the wooden structure load-bearing walls. A load-bearing wall has stiffening metal plates (30), the back surfaces of which adhere to or are in close contact with the outer surface of a load-bearing panel material (10). The stiffening metal plates reinforce a portion of the panel material through which fasteners (20) penetrate. The stiffening metal plates are disposed on the periphery of the panel material with a space (S1) substantially equal to the spacing of the fasteners therebetween. The stiffening metal plates are mutually separated, and unreinforced regions of the panel material in which the stiffening metal plates are not present are formed on the periphery. The fasteners are driven into the metal plate with a working tool. The shaft (21) of each fastener is inserted or press fit into a wall substrate (2, 3, 5) by perforating and passing through a stiffening metal plate. The stiffening metal plates hold, support, or bear the fastener heads (22) in positions that are substantially the same as the outer surface of the panel material.
