Abstract

The invention discloses a detonation protection device for a shear wall. The detonation protection device comprises at least one mesh rubber layer. Each mesh rubber layer is provided with a plurality of rope binding sets used for bundling and covering mesh rubber to a shear wall face. Compared with the existing situation that a bed straw mattress is hung on a shear wall to protect detonation flying stone, the detonation protection device can well prevent detonation flying stone from being generated, hurt to surrounding people and property losses are controlled or reduced, and accidents are reduced.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a blasting protection device for a shear wall. Background technique [0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in air, water, earth and rock media or objects to achieve the intended purpose. When the explosive package or charge explodes in the earth-rock medium or structure, the earth-rock medium or structure will be compressed, deformed, destroyed, loosened and thrown. It is mainly used in earthwork engineering, and the demolition of metal buildings and structures. [0003] The blasting of the shear walls of tall buildings is often accompanied by blasting flying rocks. In order to avoid the blasting flying rocks causing personal injury to surrounding personnel and equipment damage, the shear walls must be protected during blasting. In the prior art, the general constr...
