Beneficial effect：Triangular truss spud leg flame proection of the present utility model, the protection board generally V-arrangement knot
Structure, simple structure is manufactured easy for installation.For the Explosive Shock Loading that front meets with, the agent structure of V-arrangement can effectively put
Inclined explosive forces, i.e., disperse explosive forces along the both sides of plate, and V-arrangement angle structure compared with ordinary flat structure
Speech, with bigger strength and stiffness；For the Explosive Shock Loading that side meets with, the structure type of corrugated plating, ripple are employed
Card is when oil gas explosion impact is born, and the deformation of itself is small and with excellent explosion-proof performance and energy-absorbing effect；Thin-wall circular tube
It is a kind of excellent power-absorbing, constituting filled board as the inner lining material between inner and outer plates can energy-absorbing explosion energy well
So as to reduce the deflection of inner panel；V-arrangement ripple outside plate and V-arrangement flat board inner panel employ foamed aluminium packing material, foamed aluminium
Energy-absorbing effect is good, can further resist explosive forces, finally, auxiliary support structure is welded at the protection board rear, it is ensured that
The protection board structure safety of itself；The protection board structure is mainly used in the truss leg of self-elevating ocean platform, in blast
During generation, protection board structure gives full play to the performance for putting partially and absorbing blast impulse, so as to avoid blast load direct effect
In spud leg, great protective effect is served to spud leg.

Specific embodiment
As shown in Figures 1 to 5, a kind of triangular truss spud leg flame proection of the present utility model, including first
The generally V-shape of plate and the second support plate, the first support plate and the second support plate composition, when protection board front meets with Explosive Shock Loading
When, v-shaped structure can be very good to put inclined explosive forces, so as to avoid structure from directly bearing Explosive Shock Loading.The protection board
Triangular truss spud leg 8 is mainly used in, the significant degree of putting inclined blast impulse is considered and the low of platform deck 7 is accounted for
With area, therefore V-arrangement angle takes 60 ° (angle with triangular truss structure is approximately the same), meanwhile, in order to ensure V-arrangement angle
There is enough intensity, the utility model is welded T profile 5 on the inside of V-arrangement angle and strengthened.First support plate and the second support plate
Ripple type outside plate 1 and inner panel 3 are included, some thin-wall circular tubes 2, thin-wall circular are provided between the ripple type outside plate 1 and inner panel 3
Pipe 2 is connected by welding with ripple type outside plate 1 and inner panel 3, and the first support plate and the second support plate are welded to connect by with T profile 5, this
Sample not only can effectively put inclined explosive forces, it is ensured that the intensity of V-arrangement sharp corner structure.
In the utility model, the corrugated plating that ripple type outside plate 1 is filled using foamed aluminium, foamed aluminium energy-absorbing effect is good, with
After steel plate is filled, the intensity of itself can be strengthened again, on the basis of classic flat-plate, corrugated laterally be manufactured in planar surface
Projection 6, the spacing L between corrugated projection takes 1.22m or so, and the height h of ripple type projection takes 0.15m or so, through bulkhead
Corrugated plating research shows that consider various factors, the corrugated plating explosion-proof performance under the size is good, and deflection is small.Work as protection board
When side is subject to Explosive Shock Loading, corrugated plating can well absorb impact, and pile leg structure is played a protective role, meanwhile,
Wave structure enhances the intensity of plate itself, can replace traditional reinforcement, greatlys save material.Corrugated plating is not applying
Intensity can be still kept under conditions of reinforcement, material is saved, meanwhile, the explosion-proof performance of corrugated plating is good, deforms during by blast impulse
It is small.
In the utility model, the inner lining material between inner and outer plates selects thin-wall circular tube 2, and thin-wall circular tube 2 is a kind of fine
Power-absorbing, it is easily manufactured and with simple structure, the advantages of cheap, can be widely used as interior between two-layered steel plates
Lining material.The material of thin-wall circular tube 2 is Q235 steel, a diameter of 30cm of pipe or so, by way of welding with ripple type outside
Plate 1 and inner panel phase 3 are connected, in order to possess good energy absorption characteristics and reduce the deflection of inner panel, pipe cloth between inner and outer plates
The distance of center circle put is 50cm or so.
In the utility model, in order to simplify procedure of processing and convenient arrangement other structures, V-arrangement inner panel is filled out using foamed aluminium
The flat board for filling.Auxiliary support structure 4 is welded at inner panel rear, the structure is mainly made up of two large triangle shape steel plates, triangle
Shape steel plate is 60 ° with the angle of inner plate welding, and triangular steel plate is welded on platform deck 7, and the supplementary structure can be to whole guarantor
Backplate plays a part of support reinforcing, prevents protection board from producing and toppling because the load that is hit is excessive.
The above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
