Building roof helicopter lightweight apron
Technical field
The present invention relates to a kind of helistop, particularly relate to a kind of building roof helicopter lightweight apron.
Background technology
Roof helicopter platform refers to and is arranged on building roof for the facility that helicopter takes off, lands and stops.Helicopter platform is mainly adapted to urban disaster prevention and combats a natural disaster the fire-fighting command building at command scheduling center, important medical treatment center, deluxe hotel and highrise building etc.Popularizing of helicopter platform, significant to China's national defense, fire-fighting, first aid, special service, tourism etc.Vertically angle is evacuated from highrise building, roof helicopter platform is a kind of effective supporting facility, particularly for super highrise building, the refuge area that opens wide or partly open wide in conjunction with roof is arranged, more be conducive to succouring rapidly refugee to be out of danger, meanwhile, also can to enter building from roof for air transport fireman and carry out fire fighting and rescue.
The helicopter platform in current domestic construction field is mainly steel.Steel helicopter platform has gone out foundation construction requirement higher due to own wt big exposure, and steel platform is heavier, maintenance large and difficulty, safety factor is on the low side.In addition, no matter domestic existing platform is steel work or civil engineering, and be all that platform is directly connected with building, load when causing helicopter to land like this is directly delivered to building itself, thus higher to the requirement of strength of building itself, the energy consumption of materials is larger.
Chinese utility model patent patent No. CN201120016440.8 discloses a kind of lightweight high-elasticity anti-impact roof parking apron; it is by scratch coat; elasticity PU layer; hollow ceramic pearl mixing PU layer; high rigidity surface layer; anti-skidding weatherability surface layer, the place of laying, formation high resilience and the intensity of constructing successively by interface.This kind of apron is also that a kind of impact force that declined by helicopter is conducted to the device of building by multilayer padded coaming, and relative fabricating cost is higher, and difficulty of construction is large.
Summary of the invention
The invention provides the building roof helicopter lightweight apron that a kind of structure is simple, easy for installation, be suitable for popularization.
A kind of building roof helicopter lightweight apron, comprise apron landing panel, landing panel is provided with the constraint constraint point of helicopter and the reflecting marking for nightlanding, described landing panel is a kind of frame construction connected and composed by reinforcing rib by top panel and lower panel, landing panel lower panel bottom surface connects the support platform be made up of the mutual level connection joint of two or more crossbeam, connect the sub-truss be made up of two or more triangle space unit bottom support platform, bottom sub-truss, connect the location hook embedding building roof; Described triangle space unit is interconnected to constitute by three square tubes.This kind adopts the landing panel of frame construction to greatly reduce the weight of whole apron and the designing requirement to house weight capacity; the sub-truss that the support platform formed owing to have employed crossbeam is on the other hand formed in conjunction with triangle space unit, is uniformly transmitted to safety in utilization that flooring improve building roofing after being decomposed by the impulse force that helicopter lands by sub-truss.
The top panel of described landing panel is attached with landing net, and the impact force of uniform differentiation helicopter landing further, extends the application life of landing panel.
Described landing panel neighboring along being provided with aluminum protective screening, aluminum protective screening has for evacu-ation walk breach and the mounting groove of fire extinguisher is installed, mounting groove one end connects landing panel, is connected between the other end with aluminum protective screening by junction plate.This kind of aluminum protective screening is not only lightweight, and can bear 180kg falling bodies and freely fall power from 1.1 meters of eminences, improves the safety of apron.Fire extinguisher in described aluminum protective screening breach, fire extinguisher is overturned and can quick obtaining fire extinguisher when needed by rotating wind when this kind of set-up mode prevents helicopter from landing.
Described landing panels outside edge is provided with all cowl lamps of arranging for the floodlight of nightlanding and spacing to guide accurate, safe falling at helicopter night.
Described landing panel upper surface is provided with the guiding raised line leading to safe escape door, and guiding personnel arrive safe escape door or boarding fast.
Fire nozzle is provided with in described landing panel, fire nozzle comprises nozzle body, nozzle body periphery cover has mounting pipe, between the top panel that mounting pipe body embeds landing panel and lower panel, the top panel upper surface of landing panel is stretched out in mounting pipe body one end, and being provided with flange, the mounting pipe body other end stretches out the landing lower panel soffit of panel and the nut that has been threaded, and is fastened on by nozzle body in landing panel; Described mounting pipe connects feed pipe.Realize being fastenedly connected in the landing panel that this kind adopts the mounting pipe structure of socket nozzle body nozzle body to be embedded apron; make fire nozzle be applicable to helicopter lightweight apron, supplied water by feed pipe when needing fire-fighting fire extinguishing and improved the fire-fighting ability of apron by fire nozzle.
Described landing panel bottom margin is connected with two or more I shape crossbeam, described crossbeam is uniformly distributed around landing panel neighboring, adjacent two of crossbeam is be connected to bracing frame outside one group, two bracing frames are bolted and weld by four pipes the square protective screening framework formed, protective screening framework to be intertwined and connected aluminum protective screening by stainless steel wire, and the size of mesh opening of aluminum protective screening is not more than 50mm*50mm.This kind adopts the support frame structure of connecting cross beam to install, and protective screening is easy to connect, installation good economy performance, does not directly contact the application life that building extends safety net, has stronger weight capacity.
The present invention greatly reduces the weight of whole apron and the designing requirement to house weight capacity by the landing panel of frame construction; the sub-truss that the support platform formed owing to have employed crossbeam is on the other hand formed in conjunction with triangle space unit, is uniformly transmitted to safety in utilization that flooring improve building roofing after being decomposed by the impulse force that helicopter lands by sub-truss.
