Description

Technical Field

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

[0002] When carrying out construction projects, a large amount of money is needed to purchase materials and manpower. Various projects require multiple expenses. In order to ensure long-term project stability, it is necessary to calculate and verify the expected and actual costs required for project construction, so as to avoid unnecessary trouble caused by capital interruption.

[0003] When checking and verifying the costs required for a project, it is generally done in the office. Therefore, the accompanying desks are mostly large in size and heavy, and are not convenient to move. However, in actual work, the information of general projects is at the pressure site, and it would be more efficient to perform the verification on site. However, the existing verification equipment is not very portable, and it is not convenient to move it to the chaotic site for verification, and it is not convenient to use. Moreover, it is timely to use a lighter table-lift structure as a support plate for verification. Common plates are mostly thin and can only be used for support. When performing verification, because there are many items to be calculated, it is not possible to rely solely on paper and pen for calculation. Corresponding tools are also needed to assist in the calculation. Simple plate supports do not have storage structures, and various tools need to be stored separately, making it more difficult for workers to carry the equipment around. In addition, compared with the office, the environment on the construction site is more complex and is often accompanied by wind. Common support plates can only be used for support and lack an effective fixed structure. Workers can only rely on manually pressing the calculation paper, which is inconvenient during work.
