Problems solved by technology
[0003] Existing construction projects need to estimate the project cost before construction. The project cost estimate is calculated according to the engineering drawings. After the estimate is made, the drawings need to be expanded through the demonstration device. The existing demonstration device is The fixed demonstration board is inconvenient to carry for comparison during on-site observation, which will affect the estimation of project cost

The invention discloses a construction cost demonstration device for building construction, and the device comprises a pedestal, the upper end of the pedestal is provided with a winding mechanism, the surface of the winding mechanism is provided with an unfolding mechanism, the other end of the unfolding mechanism is provided with a fixing mechanism, one side of the pedestal is provided with a supporting mechanism, and the winding mechanism comprises a vertical plate. The device has the beneficial effects that the rotating button is rotated to drive the rotating block to rotate, the rotating block rotates to drive the groove to rotate, so that the groove corresponds to the push block, then the side plate is pushed to move, the trapezoidal groove pushes the two push rods to enter the round holes, and then the side plate gets close to the vertical plate; finally, the vertical plate is attached to the side plate, meanwhile, the rotating disc is rotated, the rotating disc drives the winding rod to rotate, the winding rod drives the drawing with the fixed surface to be wound when rotating, then the drawing is stored in the fixing frame, the demonstration device is convenient to carry, and the drawing is convenient to open for comparison during field observation.
Description
technical field [0001] The invention relates to a demonstration device, in particular to an engineering cost demonstration device for building construction, which belongs to the technical field of building construction. Background technique [0002] The project cost refers to the total fixed asset investment cost of the expected expenditure or actual expenditure of a project, that is, the sum of the one-time expenses required for a project to form corresponding fixed assets and intangible assets through construction. The project cost refers to the project price . [0003] Existing construction projects need to estimate the project cost before construction. The project cost estimate is calculated according to the engineering drawings. After the estimate is made, the drawings need to be expanded through the demonstration device. The existing demonstration device is The fixed demonstration board is inconvenient to carry for comparison during on-site observation, which will aff...
