Vault top of net shell of oil storage tank bar intermediate node.Dome roof tank net roof bar intermediate node structure disclosed by the invention includes disc-shaped component, bolt, nut, spring and pad.This Dome roof tank net roof bar intermediate node is easy for installation, and integrated stress suffered by practical application interior joint is less, utilizes the principle of buckle to be connected by node by each one-tenth shaped steel, formation net shell, and simple in construction is novel, safe and reliable.This node structure is applicable to volume at 20000m3Above vault net shell storage tank.
Description
Technical field
The present invention relates to a kind of Dome roof tank net roof bar intermediate node, belong to petrochemical industry warehousing and transportation facilities field.
Background technology
Latticed shell structure is widely used in civil engineering, and with in the majority in the large stadiums such as gymnasium, its structure and technology are all comparatively ripe.Along with the development that product oil storage tank maximizes, Spatial Lattice Shells is adopted to become inexorable trend as storage tank tank deck.Although latticed shell structure is in the existing ripe theory of building trade and design considerations, but how to be applied to large-scale storage tank and there is also a lot of technical problem.Such as some node in-site installation is not convenient, causes that installation cost is higher；Some installs conveniently node, for instance gusset-type joint, has again certain projection at node place after installing, and affects the tight laminating of molding steel screen structure and eyelid covering；And some node in the large span latticed shell structure of oil storage tank tank owing to the restriction such as deadweight can not use；Additionally also some node strengths again cannot be up to standard.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, use safe and reliable Dome roof tank net roof bar intermediate node.
It is an object of the invention to be achieved through the following technical solutions: a kind of Dome roof tank net roof bar intermediate node, including lower disk body, upper disk body, six bolts, six nuts, six band Slot shaping steel；Lower disk body and upper disk body are laterally zygomorphic regular hexagon circulus, and there is tapped through hole at hexagon drift angle place, and each edge midpoint of hexagonal configuration is provided with a slit；It is made up of the wing plate of floor, two pieces of same shapes and size and the fixed block of two pieces of same shapes and size with Slot shaping steel, two fixed blocks are separately mounted to the both sides up and down of floor left end, two blocks of wing plates are separately mounted to the both sides up and down of floor right-hand member, and leave gap between the wing plate of homonymy and fixed block；The distance L1 in gap is identical with the thickness d 2 of lower disk body and upper disk body, and the thickness d 1 of floor is identical with the width L2 of slit, the twice that height H1 is slit length H2 of floor；The floor of gap location is inserted in lower disk body and upper disk body slit opposing upper and lower；Bolt is in lower disk body and upper disk body tapped through hole opposing upper and lower, and fixes with nut.
Further, described lower disk body, upper disk body and band Slot shaping steel are Q345 steel component.
The present invention has following technical effect that
First, bar intermediate node of the present invention is divided into upper and lower two disk bodies, and convenient to disassembly, in-site installation is with low cost and reliability is higher.
Second, the whole upper lower wing plate of band Slot shaping steel groove all contacts and stress with disk body, therefore the stress suffered by node entirety is less, has been avoided as much as the phenomenon that stress is concentrated, it is ensured that the safety of node.
3rd, bar intermediate node overall dimensions of the present invention is small and exquisite, makes with Q345 steel, conducts oneself with dignity also less, and the burden of integral net shell structure is little.
4th, bar intermediate node of the present invention is connected fixing aftershaping steel wing plate upper and lower surface with one-tenth shaped steel does not have ledge, makes this node that eyelid covering and steel framework can be made when applying to oil storage tank tank latticed shell structure better to fit tightly.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Fig. 14 and 6, a kind of Dome roof tank net roof bar intermediate node, including lower disk body 1, upper disk body 2, six bolts 3, six nuts 4, six band Slot shaping steel 5；Lower disk body 1 and upper disk body 2 are laterally zygomorphic regular hexagon circulus, and there is tapped through hole 6 at hexagon drift angle place, and each edge midpoint of hexagonal configuration is provided with a slit 7；
As shown in Figure 5, it is made up of 51, two pieces of same shapes of floor and the wing plate 52 of size and the fixed block 53 of two pieces of same shapes and size with Slot shaping steel 5, two fixed blocks 53 are separately mounted to the both sides up and down of floor 51 left end, two blocks of wing plates 52 are separately mounted to the both sides up and down of floor 51 right-hand member, and leave gap between the wing plate 52 of homonymy and fixed block 53；
The distance L1 in gap is identical with the thickness d 2 of lower disk body 1 and upper disk body 2 so that the wing plate groove with Slot shaping steel 5 just blocks lower disk body 1 and upper disk body 2, secures the degree of freedom with the upper and lower of Slot shaping steel 5 and front and back.
The thickness d 1 of floor 51 is identical with the width L2 of slit 7, just blocks band Slot shaping steel 5, two, the left and right of fixing band Slot shaping steel 5 degree of freedom.
The twice that height H1 is slit 7 length H2 of floor 51 so that lower disk body 1 and upper disk body 2 just fit tightly；
As it is shown in fig. 7, the floor 51 of gap location is inserted in lower disk body 1 and upper disk body 2 slit 7 opposing upper and lower；Bolt 3 is in lower disk body 1 and upper disk body 2 tapped through hole opposing upper and lower, and fixes with nut 4.
Described lower disk body 1, upper disk body 2 and band Slot shaping steel 5 are Q345 steel component.
In the top margin of lower disk body 1 and upper disk body 2, rounding process has all been done in outside, to reduce stress concentration, increases service life.
Bolt 3 and nut 4, for fixing lower disk body 1 and upper disk body 2, according to engineering actual demand, also can add corresponding pad and spring, to increase fastening effect.
The operation principle of the present invention is as follows:
The net shell node of the present invention is mainly used on the net shell node between Dome roof tank net roof rod member, passes through into shaped steel and be connected between node, the whole latticed shell structure of final composition.The node of the present invention and the mode that the mode becoming shaped steel to be connected is draw-in groove, so increase the contact area of node and rod member, decrease stress and concentrate so that node is more safe and reliable.Meanwhile, the node of the present invention adopts orthohexagonal structure, and a node can be connected with six rods simultaneously, meets large-scale monolayer or the quantitative requirement of double-layer latticed shell structure net shell node link rod member.In addition, the node structure of the present invention is simple, and shape is less, and weight is also relatively light, and the load that therefore node itself produces for latticed shell structure is less, stablizing of favourable latticed shell structure.Owing to Large Oil Storage groove tank latticed shell structure is generally all stamped eyelid covering, and the node structure of the present invention makes the part that rod member and node point connection do not highlight, therefore when eyelid covering is changed on the net shell that steel rod member is constituted, laminating is comparatively tight, reduces eyelid covering and heaves the risk come off.
