Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] see figure 1 , figure 1 Shown is a front cutaway view of a reinforced lightweight timber shear wall. Stud 3, existing OSB panel 1, and newly added OSB panel 2 in the figure are not on the same level, so they all show partial views. For example, the existing OSB panel in the figure is represented as a fan ring, but it is not actually a fan ring, but should be the same size as the entire shear wall.

[0022] For details, please refer to figure 1 , a structure for strengthening a light wood structure shear wall, comprising stud columns 3, an existing OSB panel 1, the two are fixed by structural nails 4, and the outer layer of the existing OSB panel 1 is attached with a new An OSB panel 2 is added, and self-tapping screws 5 pass through the newly added OSB panel 2 and the existing OSB panel 1 in turn, and their ends extend into the stud ...

Abstract

The invention relates to a structure for reinforcing a light wood structure shear wall. The structure comprises a wall bone column and an existing OSB panel which are fixed through structure nails; a newly-added OSB panel is attached to the outer layer of the existing OSB panel; and a self-tapping screw sequentially penetrates through the newly-added OSB panel and the existing OSB panel, and the tail end of the self-tapping screw stretches into the wall bone column. According to the structure, the initial rigidity, ultimate bearing capacity, ductility coefficient and energy dissipation capacity of the existing light wood structure shear wall can be remarkably improved, and the overall anti-seismic property of the structure is comprehensively improved. In addition, the structure is simple, construction is convenient, engineering popularization is facilitated, and good application prospects are achieved.

Description

technical field [0001] The invention relates to a method for strengthening a light wood structure shear wall, which belongs to the technical field of light wood structure walls. Background technique [0002] Light wood structure has many characteristics such as low-carbon environmental protection, good earthquake resistance and thermal insulation performance, so it is widely used in low-rise and multi-storey wood structure buildings. During the service period, the light wood structure shear wall will be affected by the combined action of load and environmental factors, resulting in certain damage. Therefore, the strengthening method of this kind of shear wall has attracted much attention. [0003] How to ensure the cooperative performance of OSB panels and stud columns is the focus of attention in the field of light wood structure reinforcement. The rigidity and bearing capacity of traditional nail connection joints are low, and excessive plastic deformation is easy to occ...
