Description
Technical field
The invention belongs to roof system load-carrying members technical fields, more particularly, to a kind of spherical shell rack mounting process.
Background technique
Currently, spherical net rack structure is a kind of novel roof system load-carrying members, belong to multiple indeterminate space structure system,
It changes the stress of plane roof truss structure, is able to bear to the load of each side；Its structure is beautiful, rod piece regularity
By force, good integrity, space stiffness is big, and anti-seismic performance is good；Simultaneously as spherical shell grid structure uses orthogonal spatial quadrangular pyramid grid
Structure, each circle belong to sealing size after closing up, grid structure itself has sufficiently rigid can resist because of construction loads and oneself
Downwarp manufactured by body weight, so generally may not necessarily in addition increase reinforcement measure in spherical shell installation prevents node position
It moves, there is good prospect in practice of construction.
Summary of the invention
The present invention provides a kind of spherical shell rack mounting process, it has spy safe and reliable, easy for construction and economical rationality
Point.
To achieve the goals above, the technical scheme adopted by the invention is that: a kind of spherical shell rack mounting process, technique
Steps are as follows:
A, it assembles first lap lifting unit: first lap rack being divided into several lifting units, each lifting unit has three
A supporting-point；
B, assembled first lap rack frame: selecting a supporting-point is start of installation, is pacified simultaneously since the point to both sides
It is attached to and finally closes up；
C, assembled junior unit: in installation on ground list centrum, each list centrum is made of four steel poles, steel pole one of them
Fulcrum is each attached in attachment base；
D, spherical shell third layer is installed: using first lap itself as platform, single centrum being hung into design position with crane and carries out height
Sky installation；
E, base-plate and embedded part are welded: base-plate and embedded part being welded, the welding of base-plate should be uniform.
It with three supporting-points is an assembled process in the step b, when assembled along the length direction from one end to the other end
Installation is promoted, each assembling flow path elder generation lower edge assembles from end support to centre and closes up in centre, forms it into a plane,
Then it assembles and web member and winds up from centre to both ends, when assembling is made to wind up to form the slope surface of design by rod piece number.
When assembled in the step b, the bearing surface axis of supporting-point is aligned with embedded part axis, in the surrounding along bearing surface
It burn-ons several baffles.
It is adjusted after the completion of the step b, the absolute altitude for the lower edge rod piece that all supporting-points are connected with level first
It measures, measurement point is close with supporting-point as far as possible when measurement, is adjusted according to measurement data using jack pair supporting-point, adjusts
Support rod is adjusted simultaneously when whole.
The invention has the advantages that compared with the prior art: the present invention overcomes the common quality defects of assembled process, subtract
Light labor intensity, improves work efficiency, reduces labour cost, saved material, improve construction quality, it is ensured that apply
The work duration.
Specific embodiment
As described below is only presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention.
Embodiment: a kind of spherical shell rack mounting process, processing step are as follows:
A, it assembles first lap lifting unit: first lap rack being divided into several lifting units, each lifting unit has three
A supporting-point, lifting unit are completed on ground, then by crane hanging component to design position, lifting unit by three it is orthogonal just
It puts quadrangular pyramid network to be constituted, supporting-point is base-plate.
B, assembled first lap rack frame: selecting a supporting-point is start of installation, is pacified simultaneously since the point to both sides
It is attached to and finally closes up；It is an assembled process with three supporting-points in assembly, along the length direction from one end to another when assembled
It holds and promotes installation, each assembling flow path elder generation lower edge assembles from end support to centre and closes up in centre, forms it into one and puts down
Then face assembles from centre to both ends and web member and winds up, when assembling is made to wind up to form the slope surface of design by rod piece number；Supporting-point
Bearing surface axis be aligned with embedded part axis, burn-on several baffles in the surrounding along bearing surface, to prevent from moving；It was installing
Cheng Zhong, since various errors cause not connecting between some units and unit, at this moment again to axis since next point
Line is installed, and is being filled after what is do not connected the adjustment such as put down.It is adjusted after group installs, first with level by all
The level measurement for holding a little connected lower edge rod piece goes out, and measurement point is close with supporting-point as far as possible when measurement, is utilized according to measurement data
Jack pair supporting-point is adjusted, and support rod is adjusted by when adjustment simultaneously.
C, assembled junior unit: in installation on ground list centrum, each list centrum is made of four steel poles, steel pole one of them
Fulcrum is each attached in attachment base.
D, spherical shell third layer is installed: using first lap itself as platform, single centrum being hung into design position with crane and carries out height
Sky installation.
E, base-plate and embedded part are welded: base-plate and embedded part being welded, the welding of base-plate should be uniform；
When spherical shell rack third layer after the installation is completed, formed rigidity, adjust net rack support axis to design position after, according to drawing
Weld size base-plate is welded with embedded part, prevents when welding that deforming from occurring in grid structure and stress, net rack support are answered
It is symmetrically welded, such starting stage grid structure installs；Since grid structure has installed three layers, support has been welded
Finish, grid structure has formed enough rigidity, itself can bear construction loads, due to construction loads very little, will not cause to tie
The deformation of structure can trust and carry out installation in third circle grid structure.
