Description

Technical Field

[0001] This utility model belongs to the technical field of building guardrail testing equipment, specifically relating to a device for testing the resistance of building guardrails to repeated loads. Background Technology

[0002] Building railings, also known as guardrails, are partition components with a certain safety height that provide safety protection for people and prevent them from passing through. They mainly consist of posts, handrails, and balustrades. Building railings are widely used in high-rise and super high-rise buildings, observation wells in urban complexes, pedestrian corridors, pedestrian bridges, staircases, bridges, and other building and municipal engineering projects. As an important non-structural component of buildings, the safety performance and durability of building railings directly affect the safety of people's lives and property. Therefore, controlling the construction quality of building railings and ensuring their quality and safe use is crucial. Currently, the only relevant national and local specifications and standards are "Glass and Metal Railings for Buildings" (JG / T342-2012) and "Technical Specification for Building Protective Railings" (JGJ / T470-2019).

[0003] The current standard specifications recommend adding a reaction frame device to the guardrail to be tested. However, the reaction frame devices currently available on the market are relatively heavy, complex to install, have a very low safety factor, and require reinforcement with expansion bolts on the ground. Furthermore, a hydraulic testing equipment is used, extended outside the guardrail, and this presents the following problems:

[0004] (1) The entire process requires manual operation, which is inefficient;

[0005] (2) It requires the destruction of buildings;

[0006] (3) The erection of the hanging steel frame takes a long time and requires one piece of equipment to be extended beyond the guardrail, which poses a significant safety hazard to the inspection personnel;

[0007] (4) The structure is not stable and the error of the test data is too large. Utility Model Content

Moreover, the reinforcement component can reinforce the position structure of the telescopic rod component 4 relative to the base 1, which can increase the stability of the operation of the force testing component equipment and the safety of the testing.

[0038] The specific structure of the telescopic rod assembly 4 in this embodiment is as follows:
