Description
Technical Field
The invention relates to the technical field of helicopter platforms, in particular to a composite material helicopter platform.
Background
The helicopter platform is used as a supporting body for landing and taking off of the helicopter and is often configured in areas such as an offshore drilling platform, an offshore life platform, a high-end yacht, high-rise buildings and the like.
At present, the common helicopter platform materials mainly comprise steel structures, aluminum alloy structures and reinforced concrete structures. The steel helicopter platform has the main advantages of low cost and the disadvantages of heavy weight and poor corrosion resistance. The aluminum alloy helicopter platform has light weight, good corrosion resistance and high cost. Generally, when the strength is uniform, the weight of a structure using an aluminum alloy structure is about 50% to 60% of that of a steel structure. The concrete material is low in cost and excellent in pressure resistance, and the reinforced concrete structure is more applied by matching with the high tensile and compression resistance of the reinforced material in the elastic range.
Among the three materials, the steel helicopter platform is low in price, but the corrosion resistance is poor, and particularly under the condition that paint is damaged, the corrosion is accelerated, so that the safety and the reliability of the helicopter platform are greatly reduced; secondly, as mentioned above, the weight of the steel structure is about 2 times of that of the aluminum alloy structure with the same strength, and the helicopter platforms are mostly arranged in the open area above the structure, so that the influence on the gravity center position of the whole structure is large. For the floating bodies of ships and ocean engineering, the height of the gravity center directly influences the magnitude of the restoring moment of the floating bodies in the stormy waves. Compare aluminium alloy matter, the steel helicopter platform will pull high the focus of whole structure, reduces the stability radius to reduce the restoring torque, makeed the structure overturn under the external load more easily. Meanwhile, the helicopter platform is mostly arranged in the edge area of a deck in an ocean platform, and in order to keep the positive floating state of a structure, for the steel helicopter platform, the design and the operator need to execute higher requirements on the distribution of equipment, a structure and ballast, so that the flexibility of the distribution of the equipment and the structure is limited to a certain extent.
The aluminum alloy helicopter platform is expensive, has corrosion resistance superior to steel, and is an ideal material for ships and ocean structures due to light texture. Besides being expensive, the aluminum alloy structure has extremely high sensitivity of mechanical properties to temperature: at temperatures up to 400 c, the elastic modulus of the aluminum alloy will drop to about 40% of the elastic modulus at 20 c. As a result, when a fire breaks out, the aluminum alloy structure softens or collapses as the temperature continues to rise.
The concrete structure is mostly used for land buildings, and the price is lower than that of steel. The concrete material has good compression resistance, but has poor tensile resistance, and the tensile resistance is enhanced by matching reinforcing steel bars. According to the building design fire protection code: building height greater than 100m and standard floor building area greater than 2000m2The public building is suitable for arranging a helicopter apron or facilities for helicopter rescue on the roof. "because the helipad is disposed on the roof, it is obvious that if a lightweight helipad is used, more excellent stability will be obtained.
From the above analysis, it can be known that the weight, corrosion resistance, high temperature resistance and low cost of the existing common helicopter platform cannot be achieved at the same time.

The heliplatform composite heliplatform is described in detail below.
The deck 1 comprises a skeleton 11 and a plurality of deck blocks 12, the skeleton 11 and the plurality of deck blocks 12 are located in the same plane, and the upper surface of the skeleton 11 and the upper surface of the deck blocks 12 are located in the same plane, so that a bearing surface for bearing the helicopter is formed.
Referring to fig. 3, the frame 11 is in a lattice shape and has a plurality of accommodating spaces, and specifically includes a plurality of parallel and spaced transverse connecting beams 112, a plurality of parallel and spaced longitudinal connecting beams 111, and a plurality of side oblique beams 113 located on the same plane. The transverse connecting beams 112 and the longitudinal connecting beams 111 are orthogonally arranged, that is, arranged in a cross shape, the side oblique beams 113 are connected to the end portions of the transverse connecting beams 112 and the end portions of the longitudinal connecting beams 111, the side oblique beams 113 are obliquely arranged relative to the transverse connecting beams 112, and the side oblique beams 113 are obliquely arranged relative to the longitudinal connecting beams 111.
The planar projection of the skeleton 11 is in a lattice shape. The two adjacent longitudinal connecting beams 111 and the two adjacent transverse connecting beams 112 enclose to form a lattice, the oblique side beams 113, the adjacent longitudinal connecting beams 111 and the transverse connecting beams 112 enclose to form a lattice, and each lattice forms an accommodating space.
In this embodiment, the skeleton 11 has a regular octagonal shape, and the number of the side sills 113 is 4. And particularly in the present embodiment, the plurality of transverse connecting beams 112 and the plurality of longitudinal connecting beams 111 are connected by welding. The length and angle of each side of the framework 11 forming the lattice vary with the design.
The transverse connecting beams 112, the longitudinal connecting beams 111 and the side oblique beams 113 are all made of square tube steel.
The plurality of deck blocks 12 are disposed in the accommodating space of the framework 11, and the upper surfaces of the deck blocks 12 are flush with the upper surface of the framework 11, thereby forming a bearing surface.

Meanwhile, the surface anti-skid layer 121 directly bears the surface friction effect, is the first barrier layer on the surface of the whole composite material helicopter platform, and effectively protects other structures below the surface anti-skid layer 121.
The surface anti-slip layer 121 includes a plurality of protrusions disposed on the upper surface of the protection layer 122, so as to prevent slipping. Specifically, in this embodiment, the surface anti-slip layer 121 is made of silicon carbide, and is bonded with resin to connect the two.
