Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary detection of building materials, and in particular relates to a detection device for simulating the influence of load on the performance of building materials. Background Art

[0002] The impact of static and dynamic loads on the performance of building materials is a complex engineering science problem that involves the performance changes of materials under static and dynamic loading conditions. In practical applications, building materials often need to withstand combined static and dynamic loads, and understanding the behavior of materials under these conditions is essential for designing safe, economical, and durable engineering structures. Static load tests and dynamic load tests are two key test methods for evaluating the performance of building materials. Static load tests mainly evaluate the bearing capacity and deformation performance of the structure by applying static loads, while dynamic load tests are used to evaluate the performance of the structure under dynamic loads. The floor needs to have sufficient strength and durability to cope with dynamic loads to ensure its safety and reliability in long-term use.

[0003] In the prior art, when conducting dynamic and static load tests on building materials, the building materials to be tested are usually laid on the ground, and workers place heavy objects on the building materials to test the static load of the building materials to be tested. However, when testing the dynamic load of the building materials, repeated manpower movement is used to simulate walking on the building materials. The testing process is time-consuming and labor-intensive, and has poor adaptability and practicality. Utility Model Content
