Description
Technical field
The present invention relates to a kind of Dome roof tank net shell push rod 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 sports palace, 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 has ripe theory and design considerations in building trade, how to be applied to large-scale storage tank and also to there is a lot of technical problem.Such as some node in-site installation is not convenient, causes installation cost higher; Some installs conveniently node, such as gusset-type joint, has again certain projection after installing at Nodes, affects the tight laminating of shaping steel screen structure and covering; And some node in the large span latticed shell structure of oil storage tank tank due to deadweight wait limit can not use; Some node strengths again cannot be up to standard in addition in addition.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure simple, use safety, reliably Dome roof tank net shell push rod intermediate node.
The object of the invention is to be achieved through the following technical solutions: a kind of Dome roof tank net shell push rod intermediate node, comprises 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 every bar limit midpoint of hexagonal configuration is provided with a slit; Be 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 arranged on the both sides up and down of floor left end respectively, two blocks of wing plates are arranged on the both sides up and down of floor right-hand member respectively, 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 upper disk body with lower disk body, and the thickness d 1 of floor is identical with the width L2 of slit, and the height H 1 of floor is the twice of slit length H2; The floor of gap location is inserted in lower disk body and upper disk body gap opposing upper and lower; Bolt through in lower disk body and upper disk body tapped through hole opposing upper and lower, and is fixed with nut.
Further, described lower disk body, upper disk body and band Slot shaping steel are Q345 steel component.
The present invention has following technique effect:
The 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.
The second, band Slot shaping steel groove whole upper lower wing plate all contacts with disk body and stressed, therefore stress suffered by node entirety is less, avoids the phenomenon that stress is concentrated as much as possible, ensure 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, little to the burden of integral net shell structure.
4th, bar intermediate node of the present invention with become shaped steel to be connected and fixed aftershaping steel wing plate upper and lower surface there is no ledge, when making this node apply to oil storage tank tank latticed shell structure, covering and steel framework can be made better to fit tightly.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figures 1-4 and 6, a kind of Dome roof tank net shell push rod intermediate node, comprises lower disk body 1,4, six, upper disk body 2, six bolts 3, six nuts 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 every bar limit midpoint of hexagonal configuration is provided with a slit 7;
As shown in Figure 5, be made up of floor 51, two pieces of same shapes 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 arranged on the both sides up and down of floor 51 left end respectively, two blocks of wing plates 52 are arranged on the both sides up and down of floor 51 right-hand member respectively, 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 upper disk body 2 with lower disk body 1, makes to be with the wing plate groove of Slot shaping steel 5 just to block lower disk body 1 and upper disk body 2, secures the degree of freedom of the upper and lower and front and back of band Slot shaping steel 5.
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 degree of freedom of fixed band Slot shaping steel 5.
The height H 1 of floor 51 is the twice of slit 7 length H2, and lower disk body 1 and upper disk body 2 are just fitted tightly;
As shown in Figure 7, the floor 51 of gap location is inserted in lower disk body 1 and upper disk body 2 gap 7 opposing upper and lower; Bolt 3 through in lower disk body 1 and upper disk body 2 tapped through hole opposing upper and lower, and is fixed 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, concentrates, increase application life to reduce stress.
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.
Operating principle of the present invention is as follows:
Net shell node of the present invention is mainly used on the net shell node between Dome roof tank net shell push rod part, passes through into shaped steel and be connected between node, the whole latticed shell structure of final composition.Node of the present invention is the mode of draw-in groove with the mode becoming shaped steel to be connected, and so increases the contact area of node and rod member, decreases stress and concentrates, make node more safe and reliable.Meanwhile, node of the present invention adopts orthohexagonal structure, and a node can be connected with six rods simultaneously, meets the quantitative requirement of large-scale individual layer or double-layer latticed shell structure net shell node link rod member.In addition, node structure of the present invention is simple, and shape is less, and weight is also comparatively light, and therefore the load that produces for latticed shell structure of node itself is less, stablizing of favourable latticed shell structure.Because Large Oil Storage groove tank latticed shell structure is all stamped covering usually, and the part that node structure of the present invention makes rod member and node point connection not give prominence to, therefore when covering is changed on the net shell of steel rod member formation, laminating is comparatively tight, reduces covering and heaves the risk come off.
