As shown in Figure 1, the present invention provides a kind of control method of 1 line style precision of curved outside plate segmentation, in the outside plate point
Multiple control points are chosen in closing up on mouth for section 1, measure the height H1 at each control point respectively, calculate separately each described
The difference △ H of the theoretical level H2 of the height H1 and control point at control point.If △ H < -4mm, then by the control point in the outside plate
Mouthful corresponding position that closes up of segmentation 1 vertically adjusts upward the first height；If △ H > 4mm, by the control point described
The mouth that closes up that outside plate is segmented 1 corresponds to the second height of adjustment vertically down, makes the height H1 at each control point and is somebody's turn to do
Difference-the 4mm of the theoretical level H2 at control point≤△ H≤4mm.In the present embodiment, outside plate segmentation 1 close up on mouth choose it is more
A control point calculates the difference △ H of the height H1 at control point and the theoretical level H2 at the control point, i.e., will close up control point on mouth
Actual height and the theoretical level H2 at the control point compare, according to the theoretical level of the H1 at the control point and the control point
The size of the difference △ H of H2 adjusts certain height in the position for closing up mouthful Control point upward or downward, reduces control point
Difference between actual height and the theoretical level at the control point, to improve the precision of curved outside plate line style.Pass through such control
Method, the mouth line type that closes up that can be segmented 1 to outside plate during outside plate segmentation 1 is built carry out self-test and adjustment, supervise at any time
The variation of mouth line type is closed up in control outside plate segmentation 1, reduces repairing amount during subsequent construction, improves the construction effect that outside plate is built
Rate and saving construction material.
Specifically, when adjusting the Control point height for closing up mouth of outside plate segmentation 1, if the corresponding position in the control point
Place can then directly adopt fire attack correction, if having structure intersection point at the corresponding position in the control point, needing should without structure intersection point
The intersection point of structure operates on and mutually separates all parts on the intersection point, and it is strong to reduce structure of the structure in outside plate segmentation 1
Fire attack correction is reused after degree.
In the present embodiment, the control method that the curved outside plate is segmented 1 line style precision specifically includes step:
Step S10, the upper tire three-dimensional figure of the outside plate segmentation 1 is provided, the outside plate segmentation 1 is established in the three-dimensional figure
The coordinate for closing up mouth, the height H3 for closing up each position of mouth of outside plate segmentation 1 is obtained according to the coordinate.Wherein, institute
Stating coordinate is three-dimensional coordinate or two-dimensional coordinate.In the present embodiment, the coordinate is three-dimensional coordinate.
Step S20, the height of the control point corresponding position is determined respectively on the coordinate according at each control point
Spend H3, wherein the height H3 of the control point corresponding position is the theoretical level H2 at the control point.
It further include establishing table in step S20, by the height H3 of each position for closing up mouth of outside plate segmentation 1
It is recorded in the table respectively.The control point for finding out selection in the table is corresponded in the mouth that closes up of outside plate segmentation 1
The height H3 of position.It, can by the way that the height H3 of each position for closing up mouth of outside plate segmentation 1 to be recorded in table respectively
The theoretical level H2 at control point is quickly searched according to control point.
In the present embodiment, the outside plate segmentation 1 is placed on moulding bed, and the moulding bed includes at least two pillars 3, each
Datum mark is arranged in the pillar 3 in same level.The step S30 is specifically includes the following steps: provide Laser Line Marker
4, laser rays 5 first is projected using the Laser Line Marker 4 is horizontal, measures the moulding bed that the laser rays 5 is segmented 1 to the outside plate
The datum mark vertical range H4, then measure respectively again each control point to the laser rays 5 it is vertical away from
From H5, and the height H6 of the datum mark is measured, calculate the sum of H4, H5 and H6, the sum of H4, H5 and H6 are the control point
Height H1.Specifically, the datum mark is ocean punching point 2.It is completely flat for not being due to the ground of the position of 1 construction of outside plate segmentation
It is whole, datum mark is set on pillar 3, is convenient for measuring, measurement error is reduced.In addition, in the present embodiment, by using laser mark
Line instrument 4 issues laser rays 5, in specific operating process, can reduce total station completely without total station and rely on.
In the present embodiment, the difference △ H of the H1 at each control point and the theoretical level H2 at the control point are recorded respectively
Into the table, if the difference △ H of the H1 at the control point and the theoretical level H2 at the control point less than zero, are denoted as "-", if
The difference △ H of the theoretical level H2 of the H1 and control point at the control point is greater than zero, then is denoted as "+".If corresponding control point
There is "-" in the table, which is being adjusted downwards in the position for closing up mouth of outside plate segmentation 1, corresponding control point is such as
Fruit is had "+" in the table, which is being adjusted upward in the position for closing up mouth of outside plate segmentation 1, in the construction process,
It is very clear to accomplish.
Embodiment as one preferred, first height and second height are respectively less than 4mm, this design can be prevented
It only excessively adjusts the control point and closes up the corresponding height of mouth in outside plate segmentation 1.
In order to realize that curved outside plate is segmented the control of 1 line style degree of precision, need to close up each of mouth to outside plate segmentation 1
Choose a control point in a position.It certainly, in other examples, can be according to practical need in order to reduce time of construction
An appropriate number of control point, such as two, three, four or five etc. are selected in the mouth that closes up that outside plate is segmented 1, not
The particular number for choosing control point is limited.
