Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering cost, in particular to a lifting workbench used for construction engineering cost. Background Art

[0002] The cost of a construction project generally refers to the cost of carrying out the construction of a certain project, that is, all the costs used from preparation to completion, acceptance and delivery. It is composed of construction and installation engineering costs, equipment and tools purchase costs, other construction costs and contingency fees and taxes. The project cost is divided into unit project cost, single project comprehensive cost and total construction project cost. There are three calculations for construction projects: preliminary estimate, construction drawing budget and completion settlement. The construction cost generally uses the construction drawing budget. The construction drawing budget lists items one by one according to the design drawings, cost information price, bidding documents, construction contracts, and selected budget quotas, calculates the bill of quantities, and finally calculates the total price of the construction project. At present, cost engineers use calculators when calculating the project cost, and the existing calculators are directly placed on the workbench. When calculating the project cost, because there are a lot of materials involved, they are all placed on the workbench. If the calculator is placed on these materials, the calculator will seem to be particularly in the way. Therefore, a workbench that is convenient for storing calculators is needed.

[0003] A Chinese patent discloses a lifting workbench for construction engineering cost; the publication number is CN215271255U, which includes a workbench, a lifting mechanism, and an unlocking mechanism. The unlocking mechanism includes a calculator, a grip, a spring 1, an armrest, a sliding rod 3, a card block 1, a spring 2, a cover, and a positioning rod. The outer wall of the calculator is connected to the inner wall of the workbench, the outer wall of the grip is connected to the outer wall of the spring 1, the outer wall of the grip is connected to the inner wall of the armrest, the outer wall of the armrest is connected to the outer wall of the cover, and the inner wall of the armrest is connected to the outer wall of the sliding rod 3. By setting the unlocking mechanism, the card block 1 is bounced into the positioning groove 2 under the action of the spring 2, so that the installation groove can be closed.
