Communication tower development prospects are very impressive, to achieve the desired professional communication effect
In the construction of modern communication and radio and television signal transmission tower construction, regardless of the user to choose the ground plane or the roof communication tower, all play a high communication antenna, increase the communication or television transmission signal service radius, to achieve the desired professional communication effect. But also play the building's lightning protection grounding, aviation warning. And decorate the office building of the dual effect. Using four feet free structure, in line with steel design specifications.
In addition to the tower in the tower on the roof of the tower outside the tower, the ground on the space truss tower, a single tower and pull tower and so on. Space truss tower mortal made of self-reliance, with the beam connected together to bear the extent of the tower load, structural weight, etc., the degree of load from the control effect
The foundation of the upper structure of the full load safely transmitted to the foundation, and adhere to the structure of the whole unchanged, is composed of the main structure of the communication tower structure. Because the wind load is a random load, the wind size and bias with arbitrary and pulsating, the root force also has the characteristics of arbitrary and pulsating.
Underground selection and root placement are intimately related to the upper structure, the structure of the installation, the external load effect category, the establishment site and the geological premise. Reasonable foundation selection and design, on the reduction of structural costs, shorten the construction cycle and ensure that the construction of peace and stability to the main.
The space of the truss steel used in the communication tower is relatively light, and the vertical load of the platform is not large, so the triangular or quadrilateral truss tower under the top of the bottom of the tension or pressure was alternating, the tension is generally up to More than 70% of the pressure value. Truss tower of the anti-pull design of the main, and sometimes the root of the pull-resistant design from the leading effect. Single-tube communication tower for the cylindrical structure; mostly made of square plate or circular plate.
The communication tower plays an important role in the communication network system
The degree of informationization of modern society is getting higher and higher, and the whole communication tower becomes inevitable part of the lifeline project, which requires us to do more theoretical research and practice and standard preparation of communication tower.
The use of isolation means can reduce the communication tower input room and communication tower equipment, the role of equipment in order to enhance the earthquake room earthquake capacity. With the development of science and technology, the application of new technology to enhance the communication tower base station building more and more means of disaster resistance, more and more mature theory and practice will be able to greatly enhance the communications tower disaster resistance.
Based on the current situation of disaster resilience in the existing communication tower, through the investigation of the influence of typhoon, rain and snow freezing and earthquake disaster on the communication tower in recent years, the causes of damage are analyzed and the measures to improve disaster resistance are put forward.
Communication tower consists of tower body, platform, lightning rod, ladder, antenna support and other steel components, and by hot galvanized anti-corrosion treatment, mainly for microwave, ultrashort wave, wireless network signal transmission and transmission. In order to ensure the normal operation of the wireless communication system, the general communication antenna to the highest point to increase the service radius, in order to achieve the desired communication effect. And communication antenna must have a communication tower to increase the height, so the communication tower in the communications network system played an important role in the production of the national standard communications tower series of products over the years by mobile, China Unicom, telecommunications, public security forces and other departments of praise and praise.
Communication tower is a kind of signal transmission tower, also known as signal tower or signal tower, the main function to support the signal transmission, to support the signal transmission antenna. Use mobile / Unicom / traffic satellite positioning system and other communications sector
In the construction of modern communication and radio and television signal transmission tower construction, regardless of the user to choose the ground plane or the roof tower, have played a high communication antenna to increase the communication or television transmission signal service radius, to achieve the desired professional communication effect. Play the building lightning protection grounding, aviation warning.
