Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of thickness measurement, and in particular relates to a floor slab thickness detection and calibration device. Background Art
[0002] In modern building construction technology, the construction methods of floor slabs are mainly divided into two types: prefabricated slabs and cast-in-place slabs. Prefabricated slabs refer to slabs that are prefabricated according to uniform size and directly laid during construction. Since prefabricated slabs are made before construction, the use of prefabricated slabs can make construction more convenient and speed up the construction. In addition, the cost of using prefabricated slabs for construction is low, which is suitable for mass production and is widely used.
[0003] As an important part of the building's load-bearing structure, the thickness of the floor slab directly affects the structural load-bearing capacity. Measuring the thickness of the prefabricated floor slab can ensure that the floor slab thickness meets the design requirements and avoid safety hazards such as insufficient structural load-bearing capacity, cracks, and even collapse caused by insufficient thickness. However, in the actual measurement of the floor slab thickness, it is found that the existing calipers used for measuring the thickness of floor slabs generally have a fixed length of measuring arms and can only measure the thickness of the sides of the floor slab. When encountering a floor slab with uneven thickness, it is difficult to measure and obtain effective thickness data, which affects the judgment of the quality of the floor slab. For this reason, the present application proposes a floor slab detection thickness calibration device. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a floor slab detection thickness calibration device, aiming to solve the technical problem that the caliper used for floor slab thickness measurement in the prior art has a measuring arm of a fixed length and can only measure the thickness of the sides of the floor slab.
