の確立が急がれている。With the rapid movement toward digitization of broadcasting and communication, renewal plans for antenna towers (radio towers) have emerged in various places. For digitalization of radio waves, there are new antennas and transmission / reception facilities. In addition, it will take some time for general users to spread the use of digital radio equipment (telephones, televisions, radios, personal computers, etc.). For these reasons, switching from analog to digital cannot be performed at the same time, and a combined use period for both transmission and reception is required. In terrestrial wave transmission / reception by an antenna tower, a tower having a large height is required in order to enable wide-range use. Therefore, when a digital antenna tower is newly constructed on a site separate from the analog antenna tower, when both are close to each other, a large radio wave interference occurs due to reflection and shielding of each other. In addition, if a digital antenna tower is constructed in a remote location away from the current analog antenna tower, it is necessary to take measures against radio interference in a new area different from the current radio interference area due to general buildings, and from broadcasting and communication stations. A new transmission path to the antenna tower is required.
For these reasons, renewal of the current antenna tower is the best way to digitize from the viewpoint of social economy, and an antenna tower that can be equipped with new digital antenna equipment without impairing the function of the current antenna tower is Establishing a construction method is urgent.

点がある。The renewal of the antenna tower accompanying the digitization is the first attempt in Japan, and it is considered that there is no existing construction technology for the renewal of the antenna tower. Digitization started in the United States and the United Kingdom last year, but in both countries the above problems are expected to be extremely minor compared to Japan in terms of building density or cable penetration, and the United States and the United Kingdom have also renewed the antenna tower. Has not been established as a technology. In some proposals so far, it is difficult to move existing analog-related equipment, so a new funtena is installed in the unused part of the current antenna tower, and the equipment room such as the transceiver is newly built close to Or, there was a method of reinforcing the existing tower to provide a space. However, the space available for installing a new digital antenna is generally limited, and high-performance antennas are required. In addition, antennas of multiple stations are arranged at the same level. Is also a concern.
Further, the newly installed antenna is located at a lower position than the existing antenna, so that there is a drawback that the use range is narrower than the current antenna.

Assembling, assembling the tower, pull up or push up using a jack or the like so that the upper part protrudes upward from the roof of the building, and fix the tower to the building with the lower part of the tower inserted into the space. Therefore, it can be used only when constructing a new tower on the roof of the building, and the antenna tower is increased by adding a heightening structure to the middle part of the antenna tower where multiple antennas are installed on the top It cannot be applied to the height of existing antenna towers.
The lift-up method for constructing the tower (2) is as follows:
Assemble the tower in the space extending vertically in the building,
Connect the top of the hanging material to the top of the building via jack,
The lower part which is the hanging point of the hanging material is connected to the lower part of the tower, and the balance weight member is hung below the tower, so that the rising of the tower from a predetermined position in the structure to the top thereof is raised from the hanging point. Position the center of gravity of the tower below, and place the tower so that its top projects upward from the top of the building,
Lifting up with jacks and hanging materials and fixing it to the building with the lower part of the lifted tower inserted into the space, it can be adopted only when building a new tower on the building. In addition, it cannot be applied to the enhancement of an existing antenna tower in which a height-enhancing structure is added to an intermediate portion of an antenna tower having a plurality of antennas installed thereon and the antenna tower is heightened.

An upper guide ring and a lower guide ring, which are capable of standing a guide tower of a predetermined height on a steel tower foundation leg arranged below an overhead wire bridged over an arm of an existing steel tower and capable of holding a unit tower body. Is provided to move up and down in the guide tower, after connecting the unit tower carried in the lower part of the guide tower to the upper unit tower, holding the unit tower by the upper and lower guide rings The ascending, loading, connecting, and ascending steps are sequentially repeated to construct the tower from the upper part to the lower part near the ground, and at the time when the upper arm mounting portion of the tower passes the top of the guide tower, the arm is removed. Attach it to the arm bracket mounting part so that it is parallel to the existing overhead line, and when the tower reaches the predetermined height, turn the tower so that the arm bar is orthogonal to the existing overhead line, and lower the tower to the base leg of the tower. After fixing to the guide tower Because it is intended to remove was disassembled,
It can be used only when constructing a tower for supporting overhead lines to support overhead lines that are bridged between arms of existing towers, and the height is increased in the middle of the antenna tower with multiple antennas installed on top of it. It is not applicable to the enhancement of an existing antenna tower in which a structure is added to increase the antenna tower. The problem to be solved by the present invention is to provide a method for increasing an antenna tower which does not have the above-mentioned disadvantages of the prior art, in other words, using an antenna installed on an existing antenna tower. However, an object of the present invention is to provide a method for increasing an existing antenna tower, which can increase the height of the existing antenna tower without causing a radio wave interference and can install a new antenna.
