Embodiment 1

[0042] A construction method for a special-shaped curved concrete slab, the specific implementation method is as follows:

[0043] 1. Axis elevation measurement

[0044] In order to accurately and quickly measure the axis elevation of the thin plate on the curved surface, the coordinate grid measurement and positioning method is used to project the spatial surface horizontally, and divide the projection surface into several grids of 1000mm×1000mm or smaller, and then apply the formula to calculate the horizontal projection Each grid node in the surface coordinate system corresponds to the elevation of the point on the space surface, and then the elevation is marked on-site, as the basis for erecting and supporting the formwork, and all the calculated node elevations are connected together to form A smooth surface2 such as figure 1 shown.

[0045] The specific application formula is as follows:

[0046] 1.1 Calculate the vertical elevation Hc of the curve on the left project...

Embodiment 2

[0076] The rest are the same as in Embodiment 1, the difference is that: according to the different curvatures of the curved surface sheet design, the layered height of the concrete pouring on both sides of the relative boundary line 10 is controlled, and the layered height is 600mm. Concrete is piled up; the general direction of advancement is also implemented in sections, controlled at a height of 800mm.

Embodiment 3

[0078] The rest are the same as in Embodiment 1, the difference is that: according to the different curvatures of the curved surface sheet design, the layered height of the concrete pouring on both sides of the relative boundary line 10 is controlled, and the layered height is 900mm, and the layered height is 900mm, and then it will go up after the vibration is tapped in place. Concrete is piled up; the general propulsion direction is also implemented in sections, controlled at a height of 1200mm.

The method has the advantages of simple operation, strong practicability, high operation efficiency, safety, stability, economy, saving and the like.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a construction method of a special-shaped curved concrete sheet. Background technique [0002] With the continuous improvement of construction technology and people's aesthetic level, there are more and more unique curved surface designs, so the requirements for construction are also getting higher and higher. [0003] At present, for the special-shaped concrete thin-slab structure, the construction methods are different, the appearance and structural quality are difficult to control, and the design effect cannot be achieved, and most components require special customized formwork, of which steel formwork is more common. [0004] However, it requires a lot of steel, has a heavy weight, is not easy to move and install, consumes a lot of manpower and material resources, has high cost, and low utilization rate, which does not meet the basic principles of project management. ...
