Description
Technical field
The present invention relates to the peace of technical field, the particularly derrick cranes such as construction, the production of large scale equipment, transport
Fill basic technology field.
Background technology
In modern architecture, production, transportation, derrick crane is largely widely used, and it gives full play to its lifting
The advantages that amount is big, and height is high, and transport coverage is big.But due to the importance and own characteristic of derrick crane, its basis
Safety and stability problem also turns into the major issue that must take into consideration in construction, production process.
Existing derrick crane uses steel platform tower crane, there is cross type and the class of hollow two.
Derrick crane suspension column counter-force is being delivered to capital via girder steel, and the amount of calculation of various operating mode lower girder steels is larger.It is existing
The centre-to-centre spacing of pile foundation is reduced to and is equal with tower crane column middle-range or slightly larger, in this way to avoid this calculating by real many projects
Cross type and hollow steel platform produce in succession.So processing will increase the counter-force value of stake top, increase lattice column and pile foundation
Cost.And because derrick crane column spacing is little, causes pile foundation centre-to-centre spacing to be less than code requirement, do not meet《Build stake
Technical specification》（JGJ94-2008）Regulation, and the middle microcardia of pile foundation causes the deformation of pile foundation to increase because of efficiency of pile groups, stake
The vertical supporting rigidity of base reduces because of pile-soil interaction, it is impossible to effectively plays the bearing capacity of stake.
Such as：One derrick crane, model QTZ80, its performance see the table below
| FV(kN) | Fh(kN) | M(kN.m) | |
| Off working state | 449 | 71 | 1668 |
| Working condition | 509 | 31 | 1039 |
In upper table, FVFor vertical axle power；FhFor horizontal force；M is tilting moment.
Through research, pile foundation centre distance determines the size of Pile top force, also have impact on the diameter of pile foundation, length, cost.
Pilespacing is smaller, and Pile top force is bigger, and bearing capacity of single pile is smaller.To make full use of bearing capacity of single pile, should try one's best increasing
Pilespacing, and pilespacing increases, calculating cross steel joist support platform is more complicated, and general construction technical staff is difficult to be competent at, and now girder steel
Deform, shake the excessive derrick crane that easily causes and be unable to normal use.
《Build stake technical specification》（JGJ94-2008）To the existing concrete regulation of bearing pile, see the table below：
A such as derrick crane pile foundation uses the bored concrete piles of Φ 800, is learnt from table, non-crowded figure bored concrete pile spacing should be a diameter 3
Times, i.e. 3 × 0.8=2.4m.
It is numerous and diverse to avoid calculating, the centre-to-centre spacing of pile foundation is reduced to and is equal with tower crane column middle-range or slightly larger.Thus increase
Add diameter, the length of pile foundation, and increase construction costs cost.
The content of the invention
The present invention seeks to propose a kind of tower for can effectively reducing tower crane foundation cost, improving its stability
A kind of steel platform of heavy-duty machine.
The present invention includes four groups of pile foundations, coaxial steel latticework part is set up respectively in each group pile foundation, in four groups of steel latticework parts
Upper end be fixedly connected and be connected with each other the hollow basic frameworks that form by four auxiliary girder steels, the hollow basic framework is in
It is horizontally disposed, it is characterised in that：Aid in respectively symmetrically welding two branch on girder steel in relative two piece of hollow basic framework
Girder steel is supportted, two support steel beams are mutually perpendicular to this two auxiliary girder steels respectively, right between two support steel beams
Claim welding two channel-section steels, two channel-section steels are mutually perpendicular to two support steel beams respectively.
The present invention forms one big hollow framework by hollow basic framework, by two first auxiliary steel thereon
The setting of beam and two second auxiliary girder steels, the small hollow framework formed in big hollow framework, one is formd with this
The steel platform of three-back-shaped derrick crane.
Derrick crane is arranged in the steel platform of the three-back-shaped derrick crane, and its advantage is：Be advantageous to pile foundation stress
Make full use of, steel platform is reusable, and installation, dismounting speed are superior to reinforced concrete platform, so as to reduce cost, accelerate
Construction speed, reduce labor intensity；Existing safety devices software for calculation can use to calculate again, the work for reducing technical staff is strong
Degree, improve correctness, integrality, the reliability for calculating data；And pilespacing also is compliant with《Build stake technical specification》（JGJ94-
2008）Regulation requirement.
The present invention makes full use of the gross area that four pile bases are formed, by the weight of whole derrick crane and the goods of lifting
Share to the larger area, reduce pressure, with the purpose for reaching safety, reducing foundation cost cost, the in addition steel platform
Reusable, installation, dismounting speed are superior to girder steel concrete platform, accelerating construction progress.
