Description
Technical field
The present invention relates to LNG memory structures, and in particular to large-scale regular polygon LNG concrete storage tanks.
Background technology
There are mainly three types of types for large-scale liquefied natural gas (LNG) storage tank：Single appearance formula, holds formula at double volume type entirely, is cylinder
Thin-walled dome structure, in addition to holding formula entirely and being armored concrete top shell, single appearance formula and double volume type are steel-structure roof.It is cylindrical
LNG storage tank barrel is higher, compared with its space scale, is equivalent to thin-wall member, without support, horizontal Lateral resisting ability among barrel
Weaker, the outer stressed barrels deformation of plane is big, and storage tank local stiffness is weaker under horizontal force action.Position is easy to happen in seismic process
Shifting and local deformation.Cylindrical structure difficulty of construction is big, and construction technology, construction precision and control require very high.Due to designing about
Control of the fixed and large-span domes to dead weight, local steel construction or concrete slab are relatively thin, antiknock scarce capacity, when encountering conventional force
Device can not ensure safely that there are apparent security risks when attacking.To tank body partial structurtes antiknock ability is increased to and tank skin
Identical level, then construction cost will increase substantially, efficiency-cost ratio it is low, annular vault be large span thin-slab structure, single tank
There are efficiency-cost ratio bottlenecks for body enlargement.Also there is using rectangle or other shapes (LNG) storage tank, for example, my company was in 2012 months
A kind of novel rectangular tank body of 10 days 17 Chinese invention patents 2012103929114 applied and authorized, anti-lateral displacement deformation resist
Quick-fried ability is existing compared with cylindrical obviously to be enhanced.But with regular polygon described in this patent (such as regular pentagon, positive six side
Shape and octagon etc.) tank body comparison after we have found that：(1) regular pentagon, regular hexagon and octagon storage tank windward side
Structural shape factor of wind load be significantly less than quadrangle storage tank, have stronger wind resistance, antiknock ability；(2) regular polygon tank body is (such as
Regular pentagon, regular hexagon and octagon etc.) there is more preferably space anti-torsion performance, the journey of corner stress raisers
Degree is further alleviated.With internal and international situations variation, the development of technology and probably attack the renovations of means, make China and
International community faces the danger probably attacked with conventional war and is increasing, and further enhances Large LNG storage tank and other high values strategy
It builds, the safety of structures and anti-terrorism antiknock ability, the threat of terrorism is coped with for us and realizes " manufacturing products for both peacetime and wartime us " meaning very
It is great.
Invention content
For the deficiency in the presence of the prior art, the present invention provides a kind of large-scale regular polygon LNG concrete storage tanks,
Its object is to by reasonable effective building shape and structure type come improve LNG tank body lateral deformation stiffness and it is antitorque just
Degree, improves safety and the applicability of tank body, and improve efficiency of construction.
To achieve the above object, present invention employs the following technical solutions：
Including being set to the tank body on cushion cap, on the inside of tank body and cushion cap top surface is provided with thermal insulation layer；The tank body is transversal
Face is regular polygon structure；It also sets a roof beam in place with inside casing comprising several beam column/shear walls in tank body；Each beam column/shear wall is respectively just
Maximum inner diameter direction, the minimum diameter direction of polygonized structure are evenly distributed along a word；In any one beam column/shear wall
On, several inside casings are distributed with along its high uniformity and set a roof beam in place, the inside casing is set a roof beam in place to be fixedly connected and beam with adjacent beam column/shear wall
Column/between shear wall and tank wall；On any beam column/shear wall, along its short transverse it is evenly distributed have it is several in
Vierendeel girder.
The present invention increases the cross-sectional area of vertical member, substantially by the way that frame column or shear wall is arranged in tank interior
Degree improves structure lateral deformation stiffness；Identical horizontal loading or the deformation of horizontal earthquake action lower structure significantly reduce；Structure is whole
Bending resistance, shearing resistance level increase substantially：Frame column (or shear wall) and pilaster is arranged in tank body, increases the rigidity of tank skin wall about
Beam, degree of statical indeterminacy obviously increase, and the bending stiffness of structural elements (wall, plate, column) is greatly improved.Identical moment of flexure situation
Under, tank body each section flexural deformation is decreased obviously, extremely beneficial to reducing structural section and amount of reinforcement；Tank skin panel structure is excellent
Change：Wallboard is divided by components such as the beams, column, pilaster added, the enhancing of wallboard local restriction, structure plate thickness and office
Portion's stress is also greatly reduced；Top plate has broken away from the cost effectiveness bottleneck of span variation：Inner frame drastically reduces the list of top plate
Across span, the distribution of contignation bearing capacity is more efficient and rational, and utilization is more abundant.Convenient for modularization, standardized production：It is just more
Be straight line when shape plane is each, split, it can be achieved that industrialized production convenient for unit, can on-demand flexible combination, difficulty of construction drop
It is low；Traditional cross section is circular tank body when being combined, and has gap between larger circle and generates, and cross section is just polygon
The tank body of shape is then more abundant effective to the utilization in soil in combination.
