The present disclosure relates to a mounting apparatus for an antenna device on a rooftop corner, and more particularly, to a mounting apparatus for an antenna device on a rooftop corner, which enables the antenna device to be easily installed without physical changes to the exterior of a building in a state where the installation height restrictions are satisfied, enables concealable installation of an optical cable so that the optical cable is not exposed to outside, facilitates directivity adjustment of the antenna device, and does not require many workers.
It is general to install an antenna for wireless communication in a high place where the surroundings are open for smooth transmission and reception with a wireless communication device that is located far away.
For this, the antenna is installed on a utility pole, an iron tower, or a building roof (rooftop), and especially in a downtown area, the antenna is often installed on the rooftop.
In this case, in order to install the antenna on the rooftop, a method is mainly used, in which a separate support pole for supporting the antenna in an upright state is installed on the building rooftop, and the antenna is fixed and installed onto the support pole.
In this case, it is often considered that the support pole is mainly fixed and installed onto the floor surface of the rooftop by using an anchor and the like. However, in this case, it is required to drill into the floor of the rooftop in order to fix the support pole, and this necessarily entails the damage to the building. In addition, in case of installing the antenna on the building roof (rooftop), large transport machinery, such as crane, is required due to the considerable weight of installation materials including the support pole, and thus the installation cost is greatly increased.
Further, in case that the antenna device is installed on the building rooftop, there is a problem in that various kinds of legal regulations of the corresponding installation country should be satisfied. For example, in order to install the antenna device on the building rooftop in a country, such as the US, it is required that the length in a diagonal direction of the antenna device does not exceed 3 ft so as to prevent accidents due to the collapse of the installation materials caused by strong wind pressure, and there are various kinds of regulations and diverse safety standards for operations of heavy equipment, such as large crane.
The present disclosure has been devised to solve the above problems, and an object of the present disclosure is to provide a mounting apparatus for an antenna device on a rooftop corner, which enables the antenna device to be easily installed on a corner handrail of the rooftop without changes to the exterior of a building in a state where the installation height restrictions in the corresponding installation country are satisfied.
Further, another object of the present disclosure is to provide a mounting apparatus for an antenna device on a rooftop corner, which facilitates installation of the antenna device on a top part of a holding pole, and enables concealable installation of a cable so as to prevent appearance beauty from deteriorating.
In addition, still another object of the present disclosure is to provide a mounting apparatus for an antenna device on a rooftop corner, which facilitates directivity adjustment of the antenna device.

Here, for example, if the weight of the antenna device A is 30 kg, the plurality of heavy object blocks 11 may be provided as 10 or more heavy object blocks each having 30 kg so as to firmly support the weight more than 10 times the weight of the antenna device A on the bottom surface 2 on the inside of the rooftop without floating of the antenna device A. However, the number of heavy object blocks 11 is not necessarily limited thereto, and more or less than 10 heavy object blocks 11 can also be provided in consideration of the installation environment of the installed rooftop, such as wind volume and speed.
In particular, if the weight of each heavy object block 11 is 30 kg or less, even one worker can transport the heavy object block 11 by using the elevator or stairs in a building without the necessity of mobilizing heavy equipment, such as crane, and thus the installation cost and manpower can be saved.
The mounting apparatus for an antenna device on a rooftop corner according to an embodiment of the present disclosure has been designed so that the weight of not only the plurality of heavy object blocks 11 but also individual constituent elements, such as the bottom support part 10 and the handrail support part 15, 21, and 27 belonging to other installation materials, does not exceed 30 kg so that it can be sufficiently transported using only one worker's manpower.

The handrail close contact panel 23A of the seating panel part 21 may come in close contact with the outer wall of the handrail 1 and may have an area enough to endure the shaking (or gap) of the antenna device A caused by an external force, such as wind pressure, that is transferred to the antenna device A.
Accordingly, the handrail close contact panel 23A may be formed with an area which is larger than the area of the handrail spacing panel 23B that is enough to install the vibration reduction part 27 to be described later thereon.
The seating panel part 21 composed of the above-described constitution may be pre-assembled and fixed by the vibration reduction part 27 to be described later in a state where the horizontal support beam 15 is seated to surround the top part of the handrail 1 corresponding to an area that is orthogonal to the handrail 1, and the front end part of the horizontal support beam 15 may be fixed to the upper surface part.

The vibration reduction part 27 serves to make the handrail close contact panel 23A and the elastic part 30 be firmly and tightly clamped onto the inner wall and the outer wall of the handrail 1, respectively, when the clamping nut 29 is tightened.
Here, since the elastic part 30 is provided to be elastically supported on the inner wall of the handrail 1, the vibration reduction part 27 may also serve to reduce external vibrations such as floating or shaking of the antenna device A caused by wind. That is, in case that the antenna device is installed on the handrail 1 constituting the corner of the rooftop, the antenna device A is subject to frequent wind pressure by usually strong winds, and the vibration reduction part 27 has the advantage of reducing the external vibrations and being able to block noise occurrence due to the vibrations in advance because the elastic part 30 is configured to be elastically supported on the handrail 1 against the floating or shaking of all constituent elements of the bottom support part 10 and the mounting part 40 and 50 including the antenna device A.

The steering means 50 may include: a steering mounting panel 51 configured to mediate the coupling of the antenna device A onto the vertical support beam 13 and to be tilted in interworking with the tilting rotation of the antenna device A in forward and backward direction by the tilting means 40; a pair of left and right steering guide slots 52 penetratingly formed along a predetermined steering rotation trajectory in up and down direction of the steering mounting panel 51; and a pair of left and right steering guide bolts 53 configured to be fastened to a lower surface of the antenna device A through penetrating lower parts of the pair of left and right steering guide slots 52.
Here, the steering mounting panel 51 may be coupled to the top part of the vertical support beam 13 through a tilting rotation axis (not illustrated) that penetrates a tilting panel 41 and a tilting guide panel 43 of the tilting means 40 to be described later in left and right direction.
Meanwhile, as referenced in
Here, both end parts of the tilting rotation axis (not illustrated) may be hinge-fixed to a tilting axis hole 49 formed on both left and right surfaces of the top part of the vertical support beam 13.
In addition, worm wheel gear teeth 42 may be formed on an outer periphery of the bottom part of the tilting panel 41, and worm gear teeth 46 being tooth-engaged with the worm wheel gear teeth 42 of the tilting panel 41 may be formed on a part of the outer periphery of the tilting adjustment bolt 45.

More specifically, the tilting adjustment bolt 45 may have a front end part that is fixed to be rotatably supported on a hinge installation part 47A provided on the front end part of the vertical support beam 13, and a tilting adjustment part of a rear end part of the tilting adjustment bolt 45 may be installed to be exposed through penetrating the rear end part of the vertical support beam 13.
Here, a worker can adjust the tilting rotation angle of the antenna device A by setting the rotation amount of the tilting adjustment bolt 45 by using a predetermined adjustment tool that can rotate a head part (i.e., tilting adjustment part) of the bolt.
Meanwhile, the tilting means 40 may further include a tilting mounting panel 44 formed with a tilting slot 44A formed integrally with the top surface of the vertical support beam 13 and penetrated by the bottom part of the tilting panel 41 and a pair of tilting guide slots 44B penetrated by the bottom part of the pair of tilting guide panels 43.
Here, since the tilting means 40 and the steering means 50 are disposed on the top part of the vertical support beam 13 which is relatively easy for an installation worker to access, they can provide the advantage for the installation worker or a manager of the antenna device A to be able to easily adjust the directivity of the antenna device A by using the tilting means 40 and the steering means 50.
Meanwhile, a control box C may be further installed in the middle area of the vertical support beam 13, and an optical cable A-3 that connects the control box C and the antenna device A with each other may be configured to penetrate up and down the steering mounting panel 51 and to be installed in a concealable manner from the outside by a concealing cover A-2 installed on the rear part of the antenna device A.
Here, the concealing cover A-2 may serve to prevent the worker or an unspecified person who can access the rooftop from coming in contact with a plurality of heat sink fins (the reference numeral thereof is not denoted) formed on the rear part of the antenna device A for system heat dissipation and getting burned, and at the same time, may serve not to spoil the appearance of a building including the antenna device A by making the optical cable A-3 be not exposed to the outside as described above.
On the concealing cover A-2, a plurality of air flowing holes A-2h capable of making an outdoor air flow therein may be formed to facilitate heat transfer to the outdoor air through the plurality of heat sink fins.
Further, the bottom of the concealing cover A-2 and the rear surface of the antenna device A may be disposed to be spaced apart for a predetermined distance from each other, or a through-installation port may be provided between them for installation of the optical cable A-3 therethrough.
As described above, according to the mounting apparatus for an antenna device on a rooftop corner according to an embodiment of the present disclosure, since the installation of the antenna device is possible through easy height adjustment of the bottom support part 10 even without shape change of the rooftop and easy clamping and bolting coupling against the handrail 1 on the corner side of the rooftop, the ease of installation can be improved, and various kinds of regulations in the country of installation can be satisfied.
