Description

Technical Field

[0001] The utility model relates to the technical field of building detection, in particular to a detection device for the bearing capacity of a building structure. Background Art

[0002] Building bearing capacity testing is a method of evaluating the structural safety performance of a building. It determines the maximum load that a building can withstand through measurement and calculation, including static and dynamic loads. This test is essential to ensure the safety and reliability of a building, especially during the service life of the building, or before structural modification, expansion or repair. Building bearing capacity testing can be carried out using different methods, such as static load test, dynamic load test, material sampling test, etc. These methods can be used alone or in combination to ensure the accuracy and reliability of the test results. Material sampling test is a method of testing the performance of building materials. It takes samples from building materials and then conducts a series of tests on the samples under laboratory conditions, such as compressive strength, tensile strength, flexural strength, impermeability, fire resistance, durability, etc., to evaluate the physical and chemical properties of the materials. This test is very important to ensure the quality, safety and applicability of building materials. Material sampling test can be applied to a variety of building materials, such as concrete, steel, wood, asphalt, waterproof materials, etc. Through these tests, it can be ensured that the performance of building materials meets the design specifications and engineering requirements, thereby ensuring the safety and reliability of the building.

[0003] Existing compressive strength tests are usually destructive tests. During the test of concrete samples, debris is splashed. The existing treatment method is to use a protective cover to block the debris, but the blocked debris usually needs to be cleaned manually or with a vacuum cleaner. The above cleaning method has low cleaning efficiency, which reduces the efficiency and effect of compressive strength testing. Utility Model Content
