After module 103 is made, there are enough intensity and rigidity to meet and erect and translation is advisable.
C () mould has been built after, the most woven steel wire net rack is supported and the mould put up put into by outer housing, inner cover
In tool, inside and outside cover is connected effectively with steel wire net rack.To be prepared appropriate after, in mould irrigate liquid curable fill
Material (this material can be polyurethane, polystyrene, polypropylene, polrvinyl chloride or polyethylene).After certain time, fill material
Material solidification, in making mould (1), each thing becames one effectively, forms a canopy module.
D mould is removed by (), further according to span size, use several cranes, with the bottom of base as rotating shaft, lentamente will
Storage canopy canopy module is rotated to vertical direction by horizontal direction.Lifting point spacing is 30 to 40m.
E storage canopy canopy module after upright is pushed into required position along slideway by () after, and adjacent canopy module is carried out
Organic docking, and use high strength exploitation to get up in base and slideway in lower section.
According to actual needs, two sides can be closed or semiclosed.
Structural strength and Financial cost below in conjunction with the actual booth structure of storing in a warehouse previous embodiment description of engineering are carried out
It is analyzed as follows:
Structural strength analysis:
The strength and stiffness analysis of storage canopy module:
First, building the storage canopy module of width 12m, span 200m, the thickness at dome unit is set as 280mm, two
The vertical base thickness of side chooses 800mm, it is possible to ensureing enough rigidity, and be easy to construction, block mold is by length of side 4m
Finite element refines, two ends bound level displacement simultaneously and inside and outside rotation.
In vertical state, by the case of heavy load, middle cardioptosia 1.1 meters, gradient is 1.6%.Weight stress
26.4MPa, is far smaller than the allowable load of 520MPa, and the long-pending snow and ice of simulation carries, and applies the load of 0.45kN/ at top,
Big stress is 60MPa, is far smaller than the allowable load of 520MPa, meets requirement of strength；In the case of the stand under load of top, center is
Large deformation is 2.3 meters, and gradient is 2.1%, meets rigidity requirement.
Simulation wind load, applies downwards and lateral load 1.29kN/, and center radian maximum stress is 165MPa, is far smaller than
The allowable load of 520MPa, meets requirement of strength；Apply upwardly and laterally load 1.29kN/, owing to a part is offset in deadweight
Load, center radian maximum stress is 107MPa, is far smaller than the allowable load of 520MPa, meets requirement of strength；Two kinds of operating modes
Under, center maximum distortion 1.9 meters, gradient 2.2%, meet rigidity requirement.
After storage canopy block combiner is built into the storage canopy of entirety, overall rigidity and intensity all can improve further,
Build global finite element model and carry out loaded analysis, carry and in the case of wind load at same long-pending snow and ice, and consider deadweight
Load, stress concentrates on the vertical base stock retaining wall of both sides, and maximum stress is about 42MPa, and maximum distortion is the central term of dome
Portion, about 540mm, meet strength and stiffness requirement.
At present, the domestic exhausted rare span storage canopy more than 200m, actual according to engineering, use same material and knot
Structure, span is the least, then storage canopy is overall rigidity and intensity can correspondingly improve, and illustrate the most separately to less span
Storage booth structure is analyzed explanation.Certainly, in the case of span reduces, can calculate according to actual condition, reduce sheet material
Thickness and the breadth of sheet material, concrete analysis process repeats no more.
Economic cost analysis:
As a example by building a storage canopy, its specification is: span 180m, highly 50m, length 280m.
1. use integrated steel-structure mode, steel about 4000 tons, material cost about 60,000,000 yuan need to be consumed, build man-hour 2
About individual month, recruitment 50 people, add other supplementary costs, such as lifting cost, traffic expense etc., expenditure of construction is more than 80,000,000 altogether
Unit.
2. use inflated type in background technology to build way, need import thin film cost i.e. to reach 80,000,000 yuan, packing material
Expense needs 10,000,000 yuan, builds about 45 days man-hours, recruitment 50 people, adds other supplementary costs, such as lifting cost, and traffic expense etc.,
Expenditure of construction at least 12,000 ten thousand yuan altogether.
3. using the technical solution of the utility model, die cost about 10,000,000 yuan (reusable), packing material is about
10000000 yuan, other Master Cost about 10,000,000 yuan, thin film cost about 15,000,000 yuan, build 1 month man-hour, recruitment 50 people, then
Plus other supplementary costs, expenditure of construction is 60,000,000 yuan altogether.
It should be noted that this utility model, for preferable case study on implementation of the present utility model, is not made any by the above
Limit, every any simple modification, change and equivalence knot above example made according to this utility model technical spirit
Structure changes, and all still falls within the protection domain of technical solutions of the utility model.
