Abstract
The utility model discloses a triangular grid framework for an arch of an LNG storage tank. The triangular grid framework is characterized in that the triangular grid framework is adopted and welded on a ring beam at the top of a tank wall. The triangular grid framework is uniform in internal force distribution, good in stability, suitable for factory shaping production and convenient to mount.
Description
Technical field
The utility model relates to a kind of vault construction of LNG liquefied natural gas (LNG) tank, for supporting tank deck weight and the external load of LNG storage tank.
Background technique
Rock gas accounted for suitable proportion as clean energy resource in the daily fuel of its people in recent years, domestic LNG Liquefied natural gas industry fast development, and LNG storage tank list tankage size continues to increase.The rib-ring-shaped net shell vault materials that the LNG storage tank vault used is at present used are many, poor stability, manufacture mounting process complexity.
In prior art, rib-ring-shaped net shell vault is due to length degree and need band radian, and whole beam bends difficult forming.Manufacturing process of manufactory be by steel plate cut into arc again assembly welding be connected into the I-shape beam with radian, between on-the-spot mounting rail, docking welding and beam infall are welded on connecting plate, finally vuilt rib looped network shell.In this process, prefabricated, the on-the-spot installation of part all needs a large amount of welders, consumes a large amount of man-hours.In addition, part manufacture deviation, assembling deviation, welding deformation accumulation cause whole net shell size deviation, and initial geometrical defect, have influence on net shell bearing capacity and stability thus.
The network of triangle shell structure is lightweight, stressed evenly, superior in the performance of longspan occasion, but up to now, and the network of triangle shell structure is mainly used in, in the heavy construction such as stadiums, on the LNG storage tank, not being applied.
The model utility content
The utility model is for avoiding the existing deficiency of above-mentioned prior art, provides that a kind of internal force is evenly distributed, good stability, is applicable to factory's typing and produces, liquefied natural gas (LNG) tank vault network of triangle case frame easy for installation.
The utility model is that the technical solution problem adopts following technological scheme:
The characteristics of the utility model liquefied natural gas (LNG) tank vault network of triangle case frame are: adopt the network of triangle case frame, described triangular mesh frame welding is on the collar tie beam of tank skin top.
The structural feature of the utility model liquefied natural gas (LNG) tank vault network of triangle case frame also is:
Described network of triangle case frame is fan-shaped type or sunflower-shaped, or is fan-shaped type and sunflower-shaped combination.
It is to adopt I-steel or H shaped steel that described network of triangle case frame is set.
It is to adopt circular plate type node or hub formula node that described network of triangle case frame is set.
Described network of triangle case frame is set and adopts low temperature material Q345E.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model has better bearing capacity and stability under same rolled steel dosage prerequisite;
2, the utility model component are simple for production, only use cutting and boring technique, without welding, can complete in batches in manufactory;
3, the utility model site operation is convenient, but major part is worked, hand assembled completes, and to workman's technical requirements is low, also can save a large amount of man-hours;
4, the utility model processing and assembly accumulation error are little, and final whole grid precision can guarantee.
The accompanying drawing explanation
Fig. 1 is that the utility model adopts fan-shaped latticed shell structure schematic diagram;
Fig. 2 is that the utility model adopts sunflower-shaped latticed shell structure schematic diagram;
Fig. 3 is that the utility model adopts fan type and sunflower-shaped latticed shell structure schematic diagram;
Fig. 4 a is the utility model circular plate type node structure schematic diagram;
The A-A sectional view that Fig. 4 b is Fig. 4 a;
Number in the figure: 3 network of triangle case frames, 4 nodes, 41 circular plate type links, 42 are positioned at each rod member, 5 tank skin top collar tie beams.
Embodiment
Liquefied natural gas (LNG) tank vault network of triangle case frame in the present embodiment is to adopt network of triangle case frame 3, the network of triangle case frame adopts low temperature material Q345E, network of triangle case frame 3 is welded on tank skin top collar tie beam 5, according to tank diameter and sagitta, divides the footpath hoop number of plies.
In concrete enforcement, can adopt fan-shaped type as shown in Figure 1, or sunflower-shaped shown in Fig. 2, or be the fan-shaped type shown in Fig. 3 and sunflower-shaped combination.
It is to adopt I-steel or H shaped steel that network of triangle case frame 3 is set, the network of triangle case frame can adopt the circular plate type node as shown in Fig. 4 a and Fig. 4 b, the circular plate type node is that the arrangement angle direction that is positioned at each rod member 42 at circular plate type link 41 is beaten bolt hole, in the storage tank erecting bed, by bolt and tightening nut, rod member 42 and circular plate type link 41 is assembled.
Also can adopt hub formula node, press the standard implementation of the embedded hub node of JGT 136-2001 single-layer lattice shell, be assembled by bolt and tightening nut in the storage tank erecting bed.
In construction, be about each long rod member of 2-3 rice and circular plate type link all machines and numbers in manufactory, the network of triangle case frame that each assembling parts is become to need at LNG Storage Tank Construction scene, whole grid framework is welded on tank skin top collar tie beam 5, for supporting tank deck load, on network of triangle case frame upper berth, skin panel is as LNG storage tank vault.
