A kind of new antenna mounting structure
Technical field
The utility model relates to a kind of new antenna mounting structure.
Background technology
Existing antenna; as gps antenna, Beidou antenna etc. is normally directly installed on the parapet on roof; cable duct is directly through roof boarding; need bright flexible pipe to receive on parapet, without stainless steel wiring junction box, antenna is directly fixed on parapet; often bright hose coupling is difficult to reach requirement; also have this flexible pipe easily aging, just lose the protection to cable after aging, affect cable useful life.Simultaneously, cable duct directly directly penetrates from roof boarding, and penetrant structure layer not only, also penetrates watertight composition and steel and the concrete coefficient of expansion is different, easy to leak water, need pre-buried pipe sleeve or add seal ring, and cable duct need expose outside part, although be hot galvanized steel pipe, but through wiring, adapter, very easily destroying zinc layer,, still there is the possibility of later maintenance in the scene measures such as zinc that also fill spray.
Utility model content
The problem that the utility model exists for above-mentioned prior art is made improvement; be that technical problem to be solved in the utility model is to provide a kind of new antenna mounting structure; can not destroy room panel structure layer; protected building waterproof layer; reduce the possibility of building roofing percolating water; and simple in structure, easy to maintenance.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of new antenna mounting structure, comprise the built-in pipe being embedded in parapet, one end of described built-in pipe passes daughter's coping, its other end passes from wall and surface after down extending through beam and body of wall, in described built-in pipe, be provided with cable, described daughter's coping is provided with junction box, described junction box is shrouded the top of built-in pipe, described junction box's top is provided with support, on described support, be provided with antenna, described cable from support through being connected with antenna.
Further, be provided with several built-in expansion bolts on described parapet, described junction box is fixedly connected with on expansion bolt.
Further, described cable is radio frequency coaxial-cable.
Further, on described junction box's a sidewall, be provided with inspection door, described junction box is stainless steel making.
Further, when described parapet top is skewed, described junction box bottom makes junction box's horizontal positioned with waterproof mortar levelling.
Further, in the gap between described support and junction box, be filled with the glass cement of waterproof.
Compared with prior art; the utlity model has following beneficial effect: this structure is arranged cable by the built-in pipe being arranged in body of wall, beam and parapet, and in antenna bottom, junction box is set, can not destroy room panel structure layer; protected building waterproof layer; reduce the possibility of building roofing percolating water, without exposing steel pipe, can use safely; and without later maintenance; make this structure easy for installation, safeguard simple, with low cost.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Embodiment
Embodiment mono-: as shown in Fig. 1 ~ 3, a kind of new antenna mounting structure, comprise the built-in pipe 21 being embedded in parapet 2, one end of described built-in pipe 21 passes the top of parapet 2, its other end passes from wall and surface after down extending through beam and body of wall, in described built-in pipe 21, be provided with radio frequency coaxial-cable 22, the top of described parapet 2 is provided with junction box 3, described junction box 3 is shrouded the top of built-in pipe 21, described junction box's 3 top is provided with support 41, on described support 41, be provided with antenna 4, described radio frequency coaxial-cable 22 is interior through being connected with antenna 4 from support 41.
In the present embodiment, be provided with several built-in expansion bolts 32 on described parapet 2, described junction box 3 is fixedly connected with on expansion bolt 32.
In the present embodiment, on described junction box's 3 a sidewall, be provided with inspection door 31, can conveniently check inside cable wiring, described junction box 3 is stainless steel making.
In the present embodiment, for making antenna at right angle setting, when described parapet 2 tops are skewed, described junction box 3 bottoms make junction box's 3 horizontal positioned with waterproof mortar 23 levellings.
In the present embodiment, for preventing that rainwater from entering junction box 3, in the gap between described support 41 and junction box 3, be filled with the glass cement of waterproof.
In the present embodiment, by running through the built-in pipe of body of wall, beam and parapet, make the roofing 1 can be not destroyed, junction box is installed on built-in pipe, make waterproof effect better, increase useful life simultaneously.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
