Description
Technical field
The utility model relates to a kind of reflector net structure, particularly a kind of airport navigation reflector net structure.
Background technology
DVOR nodirectional beacon reflector net, with the supporting requisite reception of transmitter and reflect the antenna assembly of airborne signal in Civil Aviation System, general construction near each guidance station airfield runway outside and on flight air route, 300 kilometers of left and right of spacing, provide the navigation information of exact position to aircraft on while taking off and air route.
Traditional DVOR nodirectional beacon reflector net facility is generally comprised of five parts:
1) reflector net basis: 25 steel columns of traditional earth mat, the every corresponding basis of steel column, basic circular distribution, 1 of branch center patten, 8, inner ring basis, 16, basis, outer ring;
2) reflector net support: for avoiding around obstacle and landform to exert an influence to signal, the consideration that communications equipment room will be installed based on net sheet bottom, net sheet should be risen to certain altitude, by steel structure support and top girder steel, come supporting network sheet and antenna package system, general 1 central post, 8 interior loop pillars and the 16 outer loop pillars of adopting of prior art scheme, amount to 25 posts and support;
3) reflector net: the steel work net sheet of diameter 26 m ~ 40 m, by the little net sheet of wide approximately 1 m of some block lengths approximately 2 m, combined, little net sheet adopts band steel and twisting square steel to combine, and is similar to steel graticule mesh.According to designing requirement, reflector net diameter can be adjusted by actual demand;
4) antenna a period of time: be positioned at net sheet top, be connected with Antenna Orbit, be included in uniform on circumference 48 and 1 of home position and amount to 49 antenna a period of time, for reception and the transmitting of navigation signal, general directly purchase from overseas specialized company;
5) communications equipment room: machine room is positioned near the position of reflector net carriage center, be used for laying communication apparatus, the general concrete machine room that adopts, antenna a period of time passes the signal to communications equipment room by feeder line, because signal has decay when transmitting by feeder line, therefore feeder line length is had to strict requirement, generally should guarantee that machine room top and reflector net distance are not more than 1.2 meters.Therefore along with reflector net elevated height, machine room need to promote in the lump.
Along with modernization construction process is accelerated, various industrial construction and resident's building are day by day serious to stopping of signal, the height of the DVOR nodirectional beacon reflector net that Civil Aviation System is used at present can not meet the demands, in the urgent need to increasing the height of reflector net structure, the problem stopping to solve signal.
The problem existing in DVOR nodirectional beacon reflector net construction at present mainly contains:
1 increases the construction problem of highly bringing
1) Construction Problems of High-rise Concrete machine room

2) global stability problem of structure
Existing reflector net height is generally between 4.5 m ~ 20 m, utilize 1 central post, 8 interior loop pillars and 16 outer loop pillars and top girder steel come supporting network sheet and Antenna Orbit etc. jointly, between interior column jacket and central post due to the impact of cement machine room, can not form effective oblique pull supports, integrated steel-structure can not form stable truss, can only rely on the node rigidity between top girder steel and steel column to resist displacement, if highly continued, increase, only depend on existing bent structure form to resist the top displacement that wind load causes, very easily produce the situation of insufficient rigidity, cause displacement bigger than normal, can not meet antenna technological requirement, affect elevated height construction.
2 reflector net foundation construction problems
Existing reflector net facility basic point has 25, and rounded layout, and floor space is large, when practice of construction, because quantity is many, and angle is different, location difficulty, be easy to occur basic deviation, come to follow-up earth mat mounting strap difficult, affect the installation accuracy of girder steel and net sheet in follow-up construction.
The problem that 3 communication machine rooms and reflector net crossed construction produce
Original DVOR nodirectional beacon reflector net, reflector net support separates design and construction with cement machine room, because cement machine room need be placed near position reflector net carriage center, there is on the one hand crossed construction, there is on the other hand collision when the central post of former reflector net support and cement machine room, in addition,, in practice of construction, cement machine room affects the layout of reflector net support.
