Description

Technical Field

[0001] The utility model relates to a material checking device, in particular to an on-site material checking device, belonging to the technical field of engineering cost. Background Art

[0002] Project cost refers to the estimated or actual construction costs of a project during the construction period. The process of forecasting, planning, controlling, calculating, analyzing and evaluating project costs by comprehensively applying knowledge and skills in management, economics and engineering technology is called project cost management. During the project cost process, it is usually necessary to verify and compare two materials on site.

[0003] A Chinese patent publication (publication number: CN216534337U) discloses a field material checking device for engineering cost, including a placement plate. The advantages of the utility model are: the position of the light board is adjusted by using a universal gooseneck tube in conjunction with a torque shaft, and the light passes through the shading plates and directly irradiates the area corresponding to the material, so that the spotlight directly irradiates the content area that needs to be checked, and the spotlight emits white light to the checking part to highlight this area, and similarly adjusts the light board on the top of another material, so that the user can directly see the highlighted area when switching the line of sight to the two materials, and no need to look for it again, the checking is not tiring, and it is not easy to make mistakes; the position of the shading plate is adjustable, and the spacing between the shading plates can be adjusted by moving the ring. When the ring reaches any circular groove position, it can be moved down and stuck in the circular groove, and the position of the shading plate is limited, so that the spotlight can emit light domains of different widths to the material, which is suitable for checking content of different areas;
