Abstract
The invention discloses an SPB type LNG storage tank. The SPB type LNG storage tank comprises a supporting structure and toggle plates, wherein the toggle plates are arranged on the periphery of the supporting structure, and reinforcing annular plates are arranged on the toggle plates. The SPB type LNG storage tank disclosed by the invention solves the problem that the lifted storage tank must be cut off and the problem that lifting lugs affect insulative mounting of the tank body. The SPB type LNG storage tank is of significance of avoiding work of cutting off, polishing, repairing the lifting lugs and the like, so that the construction difficulty is reduced, the labor cost and the material cost are lowered, and the risk that breakout of a fire on an insulating material happens is reduced.
Description
Technical field
The present invention relates to a kind of LNG storage tank, particularly relate to a kind of SPB type LNG storage tank, belong to shipbuilding field.
Background technology
The Hoisting Program that SPB type LNG storage tank is traditional is SPB 4 large-scale hangers of type LNG storage tank welded top, lifting uses large-scale shackle to connect 4 hangers, after lifting terminates, cut off hanger, polish to cutting off position again, repair welding, is finally cutting off position supplementary insulation, makes whole tank body all by insulation parcel.
Traditional SPB type LNG storage tank hanger design there is problems in that
(1) traditional hanging method is at SPB 4 large-scale hangers of type LNG storage tank welded top, because SPB type LNG storage tank weight is relatively larger, is about 640 tons, so hanger size is very big, adds construction cost；
(2) needing parcel insulant outside whole tank body, hanger part is also required to install insulant, so lifting terminates rear hanger and must cut off；
(3) owing to SPB type LNG storage tank material is rustless steel, hanger material is also generally rustless steel, extremely difficult when cutting off, need the method using plasma cutting or manual polishing just can complete, and hanger thickness of slab is all relatively larger, at more than 50mm, constructional difficulties, the cycle is long；
(4) tank base insulation is just completed before lifting, and insulant is combustible material, when hanger cuts off, it is easy to occurring unexpected, domestic LNG ship several times, making period breaking out of fire, is insulant initiation on fire during construction.
Summary of the invention
It is an object of the invention to for SPB type LNG storage tank deficiency in lifting in prior art, it is provided that a kind of New type of S PB type LNG storage tank that need not install hanger additional.
In order to solve above-mentioned technical problem, a kind of SPB type LNG storage tank of the present invention, including supporting construction, bracket, described bracket is arranged on supporting construction surrounding, and described bracket is provided with enforced loop plane.
The further optimization of such scheme, is provided with hanger and strengthens plate between described bracket and supporting construction.
The further optimization of such scheme, also includes hanger reverse side and strengthens plate, and described hanger reverse side is strengthened plate and is connected with hanger reinforcement plate.
The further optimization of such scheme, described bracket is provided with two enforced loop planes.
The SPB type LNG storage tank of the present invention solves the storage tank problem that the problem that must cut off and hanger affect tank body insulating mounting after lifting terminates, meaning in avoiding cutting off of hanger, polishing, the work such as repairing, reduce difficulty of construction, save artificial and material cost, reduce the risk that insulant is on fire.

Fig. 2 is along D-D sectional structure chart；
Fig. 3 is along B-B sectional structure chart.
Detailed description of the invention
In order to make it easy to understand, we are for FSRU project.
FSRU project is that a Floating Liquefied Natural Gas regasifies storage barge, has lng regas, liquefaction, memory function.FSRU uses two SPB type LNG goods tanks, and goods tankage size is 25000 cubic metres, and each SPB type LNG goods tank weight when non-loading is about 640 tons, and overall dimensions are long 33.7mx width 25mx height 16.4m.Traditional hanging method is to use four large-scale hangers, owing to each hanger to bear the power of about 192T, needs to increase the Dynamic factor of 1.2 times during calculating, so the size of the hanger used during lifting and shackle is very big.Meanwhile, hanger cut off a lot of problem of bringing, increase difficulty of construction, increase cost, construction too increases the risk of the insulant that ignites.
The method solving above-mentioned technological difficulties is the form that hanger design adopts many suspension centres in Hoisting Program, each supporting construction is arranged around 8 hangers, 4 supporting constructions are arranged at each SPB type LNG goods tank top, amounting to suspension centre quantity is 32, so can reduce the stress of each hanger, each suspension centre stress is only 24 tons, and small-sized.Save the use of large scale hanger and shackle.Hanger is to utilize the bracket around the self structure supporting construction of SPB tank body, the form of amendment SPB tank body bracket, makes it possible to use as hanger, so tank body bracket also serves as hanger and uses.Because there being a lot of bracket also to bring convenience to hanger design around each supporting construction.Because hanger is tank body self structure, and without influence on insulation installation, so lifting terminate after without remove, save construction cost, reduced or remitted the problems referred to above brought in demolishing process.
Actual ask designed a kind of SPB type LNG storage tank for above-mentioned, including supporting construction 5 and be arranged on bracket 1 about, choose the bracket 1 of horizontal direction, every bracket 1 arranges two enforced loop planes 2, connecting steel wire ropes when enforced loop plane 2 is used for lifting by crane.It is provided with hanger in the horizontal direction between bracket 1 and supporting construction 5 and strengthens plate 3.Being additionally provided with hanger reverse side on horizontal bracket 1 and strengthen plate 4, described hanger reverse side is strengthened plate 4 and is connected with hanger reinforcement plate 3.
Although hanger design simple in construction when lifting for SPB type LNG storage tank as herein described, but it is a kind of novel mentality of designing, it is to avoid the problem that hanger must cut off after using, reduces the difficulty of construction at scene, save cost；Decrease the construction operation around SPB type LNG tank body, reduce the danger of breaking out of fire.
Claims (4)
1. a SPB type LNG storage tank, including supporting construction, bracket, described bracket is arranged on supporting construction surrounding, it is characterised in that: described bracket is provided with enforced loop plane.
