Description

Technical Field

[0001] The utility model belongs to the field of display board devices, and in particular relates to a display board for engineering cost. Background Art

[0002] The project cost refers to all the expenses spent on project construction. Its core contents are investment estimation, design budget, construction drawing budget, project settlement, final settlement, etc. It is mainly based on drawings, quotas, and list specifications to calculate the direct costs, enterprise management fees, measures fees, planning fees, profits, taxes, etc. included in the project. When budgeting the project cost, the cost estimator needs to consult a large number of design drawings and project budget quotas to obtain various data, and then use tools such as rulers, pencils, calculators, etc. to calculate the construction price of the project through various calculation rules and formulas. The series of project cost information involved is arranged in the form of posters on the project cost display board to show it to relevant personnel.

[0003] An existing engineering cost display board includes two left and right columns and a horizontal column connecting the two columns together. The display area component board is directly fixed on the columns, and a rain shelter is set on the top to cover it. Posters are pasted on the surface of the display board. This type of engineering cost display board has certain defects: 1. When it is necessary to paste and display multiple information posters, since the size of the display board is fixed, most posters cannot be pasted, which has certain limitations. Using a larger display board can paste more and larger information posters, but its large size causes it to occupy a certain space when placed, which is inconvenient to store; 2. Existing information posters are mostly pasted on the surface of the display board with glue, which is inconvenient and easy to adhere to shredded paper on the display board, affecting the appearance. Therefore, a display board for engineering cost is proposed. Utility Model Content
