A craft-type omnidirectional beacon reflection net on the roof of a building and its construction method

Abstract

A craft type omnidirectional beacon reflective net on the roof and its construction method, the reflective net is arranged on the roof of the main structure, and also includes the steel frame of the reflective net and several roof columns, the roof column is arranged on the top of the main structure, It is fixedly connected with the main structure and the steel frame of the reflection net at the same time. The column on the roof is a reinforced concrete column, which is poured integrally with the load-bearing column of the main structure, and the embedded board is buried on the side. The buried plate is welded and fixed. The reflective net is installed directly on the roof without land approval, which effectively solves the technical problems of large floor area, high material consumption, and high cost of the ground net foundation point; the height is guaranteed, the signal error is small, and the result is accurate; the roof column cooperates with the reflective net The steel frame is fixed to effectively resist the top displacement caused by wind load and ensure the rigidity. The overall stability and strength are high, which can effectively reduce the vibration and swing of the top antenna and prevent signal instability; set up fiberglass guardrails and hollow pattern plates to ensure personnel safety Strengthen the signal reflection strength.

Description

technical field [0001] The invention relates to the technical field of omnidirectional beacon reflection nets, in particular to a craft-type omnidirectional beacon reflection net on the roof of a building and a construction method thereof. Background technique [0002] The omnidirectional beacon reflection network DVOR is currently mainly a ground network, which is generally built near the outside of the airport runway and various navigation stations on the flight route. It is an antenna device that is indispensable for receiving and reflecting aircraft signals in the civil aviation system and supporting the transmitting equipment. Provide precise location navigation information to aircraft during takeoff and en route. With the acceleration of modernization construction, various industrial buildings and residential buildings are increasingly blocking signals. At present, the height of the ground grid used by the civil aviation system can no longer meet the requirements. It i...

Problems solved by technology

[0004] The purpose of the present invention is to provide a craft-type omni-directional beacon reflective network on the roof of a building and its construction method, which solves the problem that the existing ground network has a large area of ​​base points, a significant increase in materials as the height increases, and a high cost technology problems, and with the increase of height, the existing bent structure cannot effectively resist the top displacement caused by wind load, and it is easy to produce insufficient rigidity, resulting in large displacement, which cannot meet the technical requirements of the antenna, and affects the construction of height improvement. technical challenge
