Description

Technical Field

[0001] The utility model relates to the field of engineering detection, in particular to a soft heavy object impact resistance test device. Background Art

[0002] Building guardrails are widely used inside or outside buildings to separate spaces or provide safety protection. In commercial buildings with dense traffic, guardrail protection on each floor of the atrium is particularly important. The soft and heavy object impact resistance tester tests the impact resistance of the guardrail under the impact of a shotgun bag. Common guardrails are composed of railings as the main supporting components and balustrades as large surface components. The performance of the guardrail project includes resistance to soft and heavy object impact, especially the protection of the human body, that is, after the human body hits the guardrail with a certain impulse, the guardrail cannot have a relative displacement that is too large, the components are loose or fall off, and other protection failure phenomena. In the engineering inspection, a shotgun bag is used to simulate the human body, and the guardrail is hit with an energy of 300J. Whether the guardrail is damaged determines whether this performance is qualified or not. However, the existing soft and heavy object impact resistance test equipment is large, inconvenient to enter and exit the elevator, and difficult to carry. Utility Model Content
