The structural representation of Fig. 2 member.
The specific embodiment
At first,, set up the space three-dimensional model of building on computers, utilize computer to calculate the 3 d space coordinate value of each abnormity component in the building then, and calculate the coordinate figure at corresponding benchmark control point according to design drawing;
After coordinate figure calculated, at the construction field (site),,, adopt the external control method, the benchmark control point is positioned according to the coordinate figure at the benchmark control point that calculates with the central point accurate pointing of building.The external control method is a portion outside the building, utilizes transit, carries out the vertical throwing of axis according to building axis control stake and surveys.After the completion of high rise building foundation engineering, in any one axial line control stake, set up total powerstation, the coordinate figure according to the benchmark control point that calculates positions the benchmark control point.
Abnormity component number in each layer of high-rise building all may be different, so the number at benchmark control point is corresponding with the number of member in the aspect.Building is circular in the present embodiment, 8 abnormity components that evenly distribute on the circumference, so correspondence is provided with 8 benchmark control points.Fig. 1 is the distribution map at 8 benchmark control points.The O point is the central point of building among Fig. 1, and WK1 is an axial line control stake.Two relative benchmark control points and equate to the distance of building central point on an axis.The shape of one of them abnormity component as shown in Figure 2, and 8 abnormity component shapes are all identical, only dimensional orientation is variant.After the computer, the coordinate figure of each member is as shown in table 1 as calculated, and the coordinate figure at 8 benchmark control points is as shown in table 2.
