Abstract
The invention belongs to the technical field of installation of steel structures of buildings and particularly relates to a special-shaped spatial network structure node control installation method. The method comprises the following steps that (1) three-dimensional space coordinates of related control points A1(x1,y1,z1), A2(x2,y2,z2) and A3(x3,y3,z3) are obtained by means of three-dimensional modeling through a computer; (2) land samples are placed according to the coordinates (x3,y3) of the related control point A3; (3) the height of a special molding bed is selected and adjusted according to the coordinate z2 of the related control point A2; (4) the height of a threaded rod in the molding bed is adjusted; (5) after nodes are positioned, rod pieces between all the nodes are spliced in sequence according to the size relation between all the rod pieces and the corresponding nodes; (6) after splicing of a grid structure is completed, the structure is measured repeatedly. The special-shaped spatial network structure node control installation method can solve the problems that a special-shaped spatial network structure is low in splicing efficiency, and the accuracy can not be easily controlled.
Description
Technical field
The invention belongs to construction steel structure mounting technique field, be specifically related to a kind of special-shaped spacial framework node control mounting method.
Background technology
Special-shaped space structures is due to moulding uniqueness, and Form of Architecture is rich and varied, is deeply subject to liking of building designers.In order to reach a good architectural effect, and meet relevant code requirement when structure construction, the building course of this type of building, is a link of crucial importance and difficulty is larger, especially for the control of Steel Structure Installation precision.
, there are following technological difficulties in the installation of this type of space structures: one,, except the three dimensional space coordinate of node needs accurately to locate, also needs the space angle of node to position, cause the more difficult location, locus of each node; Two, because space structures is for being generally special-shaped curved, the angle of its rod member centre of form axle can change along with the variation of surface normal, causes the also more difficult accurate location of space angle of each rod member.
According to the installation of conventional full hall scaffold high altitude bulk, can cause full hall scaffold to set up that difficulty is large, consumption is large, installation effectiveness is low, and cannot solve preferably the shortcomings such as above-mentioned technological difficulties; And adopt the mounting method of burst lifting, assembled moulding bed large usage quantity, splicing accuracy are difficult for ensureing, assembled efficiency is low etc. shortcoming also cannot solving preferably above-mentioned technological difficulties simultaneously.So, how in ensureing installation accuracy, improve installation effectiveness, reduce costs and become a problem demanding prompt solution.
The technical problem existing in sum, the applicant provides a kind of special-shaped spacial framework node control mounting method, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of special-shaped spacial framework node control mounting method, to solve, the assembled efficiency of spatial special network is low, the uppity problem of precision.
For solving the problems of the technologies described above, the technical scheme that the present invention specifically provides is: a kind of special-shaped spacial framework node control mounting method, it is characterized in that, and comprise the steps:
1), by Computerized three-dimensional modeling, set up the three-dimensional entity model in the assembled process of structure, or the deduce mathematical of passing through calculates, obtain relevant control point A1 (x1, y1, z1),
