Therefore the requirement to construction is also higher and higher.
Currently, for abnormity concrete thin-slab structure, construction method is different, and appearance and architecture quality are difficult to control, can not
Reach design effect, and most of component needs specific customization template, wherein steel form relatively conventional.
But great deal of steel is needed, dead weight is larger, is not easy to mobile and installs, a large amount of manpower and materials are lost, and cost is higher, profit
It is relatively low with rate, do not meet the basic principle of engineering management.
Therefore need that a kind of formwork is convenient, workload is small, safety and stability, the construction method of economy.
Invention content
The present invention provides a kind of construction method of abnormal curved surface concrete thin plates, it is therefore intended that solves in above-mentioned background technology
Current common customization steel form dead weight is larger in the abnormity concrete thin-slab structure of proposition is not easy to mobile and installs, is lost greatly
Measure that manpower and materials cost is higher and the relatively low problem of utilization rate, the present invention have easy to operate, highly practical, operating efficiency is high,
The advantages that safety and stability, economy.
To achieve the above object, the present invention provides a kind of construction method of abnormal curved surface concrete thin plates, including following step
Suddenly：
Step 1, measurement and positioning
With reference to finite element split plot design, the sky that calculation formula calculates any point on abnormal curved surface is converted by coordinate plane
Between absolute altitude, carry out curved sheets axis absolute altitude pilot measurement space curved surface is carried out by horizontal throwing using coordinate grid measurement and positioning method
Shadow is that the floor projection of curved surface is divided into several 1000mm × 1000mm unit grids below by foundation with axis, reapplies
Formula calculates the absolute altitude for corresponding to point on space curved surface in horizontal plane coordinate system at each grid node, then will mark
