Abstract
The invention discloses a spatial measuring method of a spherical net brace. The method uses an total-station instrument without a prism to carry out spatial orientation measurement of an optional ball according to two fundamental points introduced by the known city coordinate system to a job location of a net brace, and ensures that each ball joint measures four coordinates. The four coordinates of each ball joint are substitute into an equation, a spatial coordinate of the ball joint can be determined, thereby whether the spatial location of the spatial ball conforms to design requirements can be easily analyzed.
Description
Technical field
The invention belongs to technical field of buildings, be specifically related to the space orientation method of inspection of solder sphere in the solder sphere rack work progress.
Background technology
At present, a large amount of public buildings has adopted the grid structure of large span, moulding complexity, the position of space ball node accurately is the emphasis difficult point of assembly unit control, but the construction and installation environment of rack has determined very difficulty of space measurement location, tradition is subjected to the restriction of site environment factor very big by the localization method that, subsidiary personnel and utensil cooperate, particularly the monitoring before and after the rack unloading is checked and accepted, the total assembly is finished the back and loading is finished in the inspecting for acceptance of rear space position, operational hazards and effect are low, and measuring accuracy is unsatisfactory.
Summary of the invention
At the deficiency of prior art, the invention provides a kind of spatial measuring method of spherical net brace.
Below introduce the spatial measuring method of a kind of spherical net brace of the present invention in detail, finish as follows:
A, application non-prism total powerstation are measured any coordinate (x of space ball upper surface at 4

2, y
2, z

B, by system of equations can calculate sphere centre coordinate (X0, Y0, Z0);
Wherein equation is:
(x

R is the radius of space ball in the formula.
Advantage of the present invention is: introduce two reference points in rack working-yard according to known city coordinate system, the space orientation of using the non-prism total powerstation can carry out free kick is measured, guarantee four coordinates of each ball node measurement, four coordinate substitution equations of each ball node can be obtained the volume coordinate of this ball node.Whether the locus that so just can be relatively easy to analyze the space ball adheres to specification.
