Description

Technical Field

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

[0002] Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Steel structure is easy to rust. Generally, steel structure needs to be rusted, galvanized or painted, and maintained regularly. The characteristics of steel are high strength, light weight, good overall stiffness, and strong resistance to deformation. Therefore, it is particularly suitable for the construction of large-span, super-high and super-heavy buildings. Therefore, steel materials also need to be tested before use to test their strength, internal air density, compressive strength, etc.

The utility model drives the active rod and the first gear to rotate by starting the motor, thereby driving the second gear meshing with the first gear to rotate, and then the first threaded rods at both ends will rotate. Due to the existence of the thread, the support plate can be driven to slide and adjust along the inside of the rectangular opening, thereby driving the first clamping plates at both ends to clamp and fix the steel structure placed on the top of the detection platform, which can be applied to steel structures of different lengths.
