Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a building steel structure strength detection device. Background Art

[0002] Building steel structure is a new type of building system. Compared with traditional concrete buildings, steel materials are used instead of reinforced concrete, which has higher strength and better earthquake resistance.

[0003] In the prior art, the strength test of building steel structures is often carried out by using a Leeb hardness tester, which is a non-destructive testing method for the tensile strength test of building steel structures. Before the test, a steel material standard block is used to verify the accuracy of the Leeb hardness tester, and then the test work begins. The end of the impactor connected to the Leeb hardness tester is placed against the surface of the building steel structure to be tested. The impact direction should be perpendicular to the object to be tested. By pressing the release button on the impactor, its end is used to impact the surface of the building steel structure to be tested. During the impact operation, multiple areas are selected and the average value is taken. The strength value of the building steel structure is obtained by conversion.

[0004] However, when using an impactor to perform strength testing on a building steel structure, the verticality of the end of the impactor and the surface of the building steel structure often needs to be manually identified, which requires the tester to control the vertical direction of the impactor by himself. Since the contact surface between the end of the impactor and the building steel structure to be tested is small, the tester is prone to tilting when holding the impactor against the building steel structure to be tested, which makes it difficult for the tester to control the verticality of the impactor well. The tilt of the impactor affects the accuracy of the strength test of the building steel structure. Utility Model Content

[0005] The purpose of the utility model is to provide a building steel structure strength testing device to solve the problem proposed in the above background technology that when an impactor is used to perform strength testing on a building steel structure, the verticality of the end of the impactor and the surface of the building steel structure often needs to be manually identified, which requires the testing personnel to control the vertical direction of the impactor by themselves. Since the contact surface between the end of the impactor and the building steel structure to be tested is small, the testing personnel are prone to tilting when holding the impactor against the building steel structure to be tested, which makes it difficult for the testing personnel to control the verticality of the impactor well. The tilt of the impactor affects the accuracy of the strength test of the building steel structure.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a building steel structure strength detection device, the building steel structure strength detection device comprising:

[0007] A Leeb hardness tester and an impactor; an annular groove is provided on the surface of the impactor, and an annular plate is sleeved in the annular groove;

[0008] An adjusting tube; a support plate is provided in the adjusting tube, and a positioning hole is opened on the surface of the adjusting tube; and

[0009] The shell is arranged on the surface of the supporting plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] This utility model proposes a building steel structure strength detection device;

[0017] 1. Before using the impactor to press against the surface of the building steel structure to test its strength, the distance between the shells is increased by pulling the support plate outward to make it move outward. The shell and the end of the impactor are pressed against the surface of the building steel structure to work at the same time. The shell effectively increases the contact area between the end of the impactor and the surface of the building steel structure, thereby avoiding the impactor from tilting due to too small a contact surface when pressing against the surface of the building steel structure, effectively ensuring the verticality of the impactor and the building steel structure during testing, thereby effectively improving the accuracy of the strength test of the building steel structure;

[0018] 2. The adjusting tube is used by being set in the annular groove through the annular plate. The use orientation of the adjusting tube can be adjusted by rotating the annular plate. When the support plate is pulled out, its inner end moves in the adjusting tube. The support plate is positioned by the damping block inserted into the positioning hole to achieve stability during use. A plurality of positioning holes are provided to achieve the effective adjustment of the extended length of the support plate according to different use requirements, so that it can be effectively adjusted according to the different shapes of the building steel structure, ensuring that the shell is fully against the surface of the building steel structure for use, so as to achieve the improvement of its use effect;

[0019] 3. When the impactor is not in use, push the support plate inward to shorten the distance between the two, so that the two sets of shells are clamped on the impact end of the impactor, and the two sets of shells are positioned by clamping the rubber block into the clamping groove. The shell effectively protects the end of the impactor to prevent damage to the impact end when the impactor falls or collides, so as to improve its use effect. BRIEF DESCRIPTION OF THE DRAWINGS
