List containing moisture-proof and corrosion-proof device for civil engineering cost management

Abstract

The invention discloses a list containing moisture-proof and corrosion-proof device for civil engineering cost management, and belongs to the technical field of engineering cost management. A list containing moisture-proof and corrosion-proof device for civil engineering cost management comprises a containing box, a rubber sealing pad is fixedly arranged at the edge of the bottom face of a box cover, a sealing groove is formed in the position, opposite to the rubber sealing pad, of the top face of a box body, an extrusion plate is arranged on the front side in the box body, and an extrusion pad is fixedly arranged on the front wall of the extrusion plate; a plate groove is formed in the upper end of the inner wall of the box body relative to the end portion of the extrusion plate, compression springs are fixedly arranged between the rear walls of the two ends of the extrusion plate and the rear walls of the two plate grooves respectively, a bottom groove is formed in the bottom face of each plate groove, a filter plate is embedded in the inner wall of each bottom groove, and a damp-proof assembly is arranged in each bottom groove. The moisture-proof and anti-corrosion effects of the project cost list are achieved, the protection of the list is greatly improved, and the orderly development of project cost work is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of engineering cost management, and more particularly, to a device that can prevent moisture and corrosion by storing a list used for cost management of civil engineering. Background technique [0002] Project cost refers to the construction cost that constitutes the estimated or actual expenditure of the project during the construction period. The knowledge and skills of management, economics and engineering technology are used comprehensively to predict, plan, control, calculate, analyze and evaluate the project cost. The work process is called project cost management. According to the procedures, methods and basis stipulated by laws, regulations and standards, the prediction or determination of the project cost and its constituent content is called project valuation. The project valuation basis includes and valuation content, In the process of calculating the project cost, the staff needs to carry...

[0002] Project cost refers to the construction cost that constitutes the estimated or actual expenditure of the project during the construction period. It comprehensively uses the knowledge and skills of management, economics and engineering technology to predict, plan, control, account, analyze and evaluate the project cost, etc. The work process is called project cost management. In accordance with the procedures, methods and basis stipulated in laws, regulations and standards, the prediction or determination of project cost and its components is called project valuation. The project valuation basis includes the content of valuation, Valuation methods and price standards related to engineering measurement and valuation standards, project valuation quotas, and project cost information. During the calculation of project cost, the staff need to carry out calculations through various project lists and price documents and other materials. With the construction content The number of lists will also increase accordingly, so how to keep the lists is a crucial issue. Most of the existing methods are to clamp together the documents of the same category through clips and stack them in the filing cabinet, so that Although the method is convenient to pick and place, the protection of the list will be greatly reduced, especially in the rainy season with heavy humidity, the resurgence in the filing cabinet will easily affect the list, and even cause the loss of data on it. In severe cases, batch corruption of the list may even occur, which will bring great hidden dangers to the calculation of project cost

[0003] In addition, although a large number of lists can be clamped by the clip to achieve a fixed effect, the staff needs to reopen the clip every time a new list of the same category is added. At this time, the list that has lost the limit will be scattered, so the staff needs to Reorganizing it adds a lot of unnecessary labor. In other existing patented solutions, a dry bag with quicklime is used or the board body is mixed with quicklime powder to achieve the adsorption of moisture. The design can only be used for short-term drying assistance, and quicklime will cause the risk of lime powder pollution; other solutions use anti-corrosion solution, but the process of adding and replacing the anti-corrosion solution is cumbersome
