Description

Technical Field

[0001] The present invention relates to the field of construction cost calculation, and in particular to a construction cost comparison and calculation device and a comparison and calculation method. Background Art

[0002] Cost refers to the total cost of a project, including construction and installation costs, equipment and tools, tools purchase costs, other construction costs and contingency costs. It covers the costs of each stage from project approval, design, construction to completion acceptance. Due to the large amount of cost data, it is necessary to compare the various cost data during the construction process. In order to reflect the intuitiveness of the various cost data, two cost data files are generally put together for comparison and calculation. The cost comparison and calculation device is an important tool in the field of engineering equipment technology. It is mainly used for cost comparison and calculation in the process of engineering cost, so as to improve the accuracy and efficiency of engineering cost.

[0003] The patent application with announcement number CN219133665U is a cost comparison and calculation device, which includes a bottom box for holding tools and materials, and the inner wall of the bottom box is rotatably connected to a fixed plate, and the fixed plate is provided with a support for supporting the fixed plate on the side of the fixed plate close to the bottom box, and the fixed plate is rotatably connected to a rotating plate on the side away from the bottom box, and a rotating assembly is provided between the rotating plate and the fixed plate at the rotating connection. When the rotating plate is attached to the fixed plate, the side of the rotating plate away from the fixed plate is rotatably connected to a top plate, and the top plate and the rotating plate are self-locking through friction. This application has the effect of fixing multiple documents at the same time, so that the engineering cost engineer can compare documents and data.

[0004] The existing cost comparison and calculation device fixes two groups of files on two groups of boards during use, so that the calculation personnel can directly visually observe the difference between the two groups of data. However, this method can only compare two groups of data at a time, and the cost data covers a wide range, so it is impossible to compare multiple groups of data at a time. When a board that can fix the files is added, the size of the device will inevitably increase, reducing the convenience of carrying the device. In addition, during the data comparison process, since the differences between the two adjacent groups of files can be more intuitively seen, each group of data files needs to be constantly changed. Even if a board for placing files is added to the existing device, in order to more intuitively feel the differences in data, it is also necessary to adjust the placement position of each group of files in the subsequent comparison process of each group of data, thereby reducing the efficiency of the data comparison process and increasing the cumbersomeness of the data comparison process, which indirectly affects the thinking of the calculation personnel.
