hemical anchor bolts are commonly used as reinforcement anchor bolts in engineering buildings, and their quality will directly affect the anchorage performance and product quality of engineering projects. Therefore, an indispensable step in our use is to test the quality of the anchor bolts. Today, the editor will introduce to you the method of detecting the quality of anchor bolts, so that everyone can prepare before the start of construction, improve the efficiency of the project and ensure that the project can be completed in time.
When it comes to the detection method of chemical anchors, the first thing mentioned is the pull-out test that many people will use. The pull-out test is to carry out a force test on the anchor bolt. Through the test, it can be checked whether the horizontal tension of the anchor bolt meets the national standard. Only when it meets the standard can the construction be carried out. When you buy, the manufacturer will issue a relevant inspection report, but in order to ensure that nothing goes wrong, we should also conduct a pull-out test to test it before starting work.
The specific test method of the pull-out test should be analyzed in detail, and different types of reinforcement objects need to match the actual pull-out operation. For example, for the anchoring of marble steel bars, we will also use cars and wire ropes to test. This test method is very simple and requires less space and operation. When carrying out the pull-out test, the sampling of anchor bolts must be done well. Choose the same batch and the same type of chemical anchor bolts, and the selection of the test site should adhere to the principle of easy repair, and try to avoid damage to the site. In the selection of structural parts, the quality of the structural parts anchored by steel bars must also be checked, and the pull-out test should be carried out with structural parts without obvious damage and defects. The number of samples should be kept within 5 units, and the inspection results should be recorded at any time, which is conducive to the issuance of relevant inspection reports after the drawing test is completed.
In addition to checking the quality of chemical anchor bolts through pull-out tests, you should also pay attention when purchasing anchor bolt products. You need to check the production report issued by the manufa
