Description

Technical Field

[0001] The utility model relates to the technical field of verification boards, and more particularly to a portable verification board. Background Art

[0002] Construction cost refers to the total cost of all expenses incurred during each stage of the construction process, from project planning, design, construction, to final acceptance. It consists of two main categories: direct costs and indirect costs. Direct costs primarily include labor, materials, equipment, and construction equipment usage fees; indirect costs primarily include project management fees, design fees, supervision fees, and consulting fees. During the construction cost calculation process, verification boards are required to verify the design or calculation results to ensure data accuracy. Most existing verification boards are intelligent devices, generally consisting of a display screen and structural analysis software, to verify the safety and cost-effectiveness of the structural design.

[0003] However, most of the existing verification boards do not have a protective structure, and the display screens are directly exposed to the external environment. Due to the complex environment of the construction site, if the verification board falls, the display screen is easily damaged, which reduces its service life.

[0004] And when carrying it, most of them are carried by hand. Since most of the verification boards are designed to be flat, it is not convenient to pick them up. Secondly, the surface of the display screen is relatively smooth and it is easy to slip and break. Utility Model Content
