Description
Technical field
The invention belongs to building engineering field, particularly relate to a kind of space net rack with spiral regulation support unit and build
Method.
Background technology
Space grid structure is a kind of Spacial Frame Structures, has three-dimensional loading characteristic, can bear the effect of all directions, and
And grid structure is generally high order redundant structure, if a bar partial failure, less a degree of statical indeterminacy, internal force can be again
Adjusting, total did not the most lose efficacy, and had higher safety stock.Its rod member crossed in the air had both been stressed member, again
For supporting rod member, mutual when working is for supporting, and collaborative work, therefore its good integrity, good stability, space stiffness is big, can have
Effect bears non-symmetrical load, load and dynamic load, and has preferable anti-seismic performance.Meanwhile, under joint load effect,
Each rod member is primarily subjected to axial pulling force and pressure, can give full play to the intensity of material, saves steel.And grid structure combination
Regular, great deal of nodes and the shape of rod member, equivalently-sized, and rod member and node specification less, it is simple to produce, product quality
Height, on-site consolidation is easy, can improve speed of application.
Grid structure not only achieves the rod member utilizing relatively small dimension to build longspan structure, and structure takes up room
Less, more can effectively utilize space.But there is problems of, space grid structure of the prior art builds complexity, and
Once it is difficult to after installation be adjusted, when structure partial needs to make adaptability fine setting, generally requires and carry out overall weight
New design is built, and is extremely difficult to.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of space net rack side of building with spiral regulation support unit
Method, it is possible to build space net rack quickly and easily, and local adaptation fine setting can be completed.
Adopt the following technical scheme that for this: a kind of space net rack building method with spiral regulation support unit, its
It is characterised by taking following steps:
1) assembled spiral regulation support unit, described spiral regulation support unit includes steel pipe scaffold, jacking and steel plate, jacking
Being bolted, with steel plate, the support platform frame that composition is removable, jacking lower end, for having threaded screw rod, is screwed in by screw rod
In scaffolding steel pipe, scaffold and jacking is made to constitute adjustable flexible connection；Cylindrical is arranged on described steel plate
Support steel pipe, in order to support ball node；
2) by space grid structure division unit, integral space truss structure is divided into some the most single according to actual size planning
Unit；
3) splicing ground lifting elements, first arranges assembled moulding bed, and described moulding bed is made up of, often 4 spiral regulation support units
Connected fixing between individual spiral regulation support unit by rod member；Then on spiral regulation support unit, ball node is lifted, and
Lower boom is lifted respectively between two ball nodes；Complete welding of string ball and rod member；Repeat abovementioned steps, lift two winded up
Ball node and top boom；Fill a vacancy afterwards web member, complete the splicing of ground lifting；
4) lifting of lifting elements is carried out: first first row lifting elements inside lifting；Secondly lifting second row lifting elements；It
Rear lifting the 3rd row's lifting elements, and carry out front two rows and fill a vacancy；The like complete lifting elements and fill a vacancy；Finally carry out rack
Unloading.
Further, in step 4) hoisting process, lifting uses suspender belt colligation node, and 4 lift, and wherein two
Point coordinates chain block to adjust angle；Calculate suspender belt stress according to lifting elements weight, suspender belt angle, dynamic load factor etc., sentence
Break and whether meet demand.
Further, when lifting elements lifts in step 4), draw at lower edge and set two cable wind ropes, prevention unit mistake
Degree swings.
Further, scaffold sets temporary support, in order to support lifting elements.
During lifting, according to space grid structure division unit establishment each unit weight and lifting operating mode table, when load ratio surpasses
The unit crossing 90% uses two-shipper platform to hang；Crane gear carries out Reasonable load distribution, and construction weight must not exceed two cranes and sets
The 75% of standby rated load weight summation, the loading of separate unit crane gear must not exceed the 80% of rated load weight.
During specific works, carrying out building of space net rack according to above-mentioned steps, described spiral regulation support unit can be to ball
The altitude mixture control of node controls.For the location of grid node, owing to being 3 d space coordinate location, under ball node, arrange one
Adjustable bracing frame, spiral is placed on supporting steel pipe, by regulating the absolute altitude of four jackings, by the position of movable supporting frame
Adjust the horizontal level of spiral, strong point when the most both can install as rack, bear construction load, again scalable rack
The coordinate of spiral node.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of spiral of the present invention regulation support unit.
Detailed description of the invention
See accompanying drawing.The present embodiment, as a example by two layers of grid structure, carries out building of space grid structure, especially by with
Lower step: 1) assembled spiral regulation support unit, described spiral regulation support unit includes steel pipe scaffold 1, jacking 2 and steel plate
3, jacking 2 and steel plate 3 are bolted and form removable support platform frame, and jacking 2 lower end is for having threaded screw rod 4, foot
The work layer of hand cradle arranges vertical longitudinal inner thread steel pipe, screws in scaffolding steel pipe by screw rod 4, makes scaffold and jacking
Both constitute adjustable flexible connection；Cylindrical support steel pipe 5 is set on described steel plate, in order to support ball node；Described
