Definitions

  • the invention relates to high-rise structures for the placement of technical means that require for their normal operation of the installation with a specific directivity, namely for: antennas, with a narrow radiation pattern; air optical communication devices; optical surveillance devices such as cameras of the visible and infrared ranges used to protect various objects and the state border as well.
  • the displacement of the upper platform with a wind of 25 m / s is about ⁇ 0.1 m.
  • the platform is tilted by an angle of the order of ⁇ 1 degree.
  • Modern optical devices that allow observation at distances of up to 10 km have an angle of view of less than one degree. Accordingly, when the mast is tilted by the wind by 1 degree, the distant object will simply leave the field of view of the operator. In this case, the speed of movement of the picture on the screen will be so large that the operator will not be able to clearly see anything on it.
  • the mast that is supposed to be used for remote control must meet a number of the following stringent requirements.
  • the mast should function reliably around the clock and year-round in all weather conditions, including with strong wind alternating loads.
  • the mast must provide sufficient vertical load for installation of the devices and do not require maintenance in the mode of long service life (the service life of the mast is not less than 10 years). This is due to the need to install it in remote areas, where it is possible to get no more than once a year due to natural conditions and bad roads.
  • the mast should not differ significantly in terms of mass and size characteristics from the traditional masts currently used. Otherwise, the applicability of such a mast will be very limited due to its weight and size parameters and, accordingly, the difficulties arising during delivery and installation at the place of operation. Fourthly, the mast should have a simple design, providing for its direct assembly at the installation site, which greatly simplifies its use in hard-to-reach areas.
  • the mast should not require additional energy supply for its operation, which is especially important in the conditions of remote, sparsely populated areas.
  • the main disadvantage of the known device is that the fixing of the mast occurs on one and the same level, whereas its parts, which are above and below this second ring, continue to experience wind loads and bend.
  • the only difference is that the shorter sections of the mast are bent. That is, the task of stabilization in the direction of the upper platform of the mast is solved only partially. The slope of the upper platform of the mast, when exposed to wind load, will only slightly decrease.
  • the closest to the claimed solution is a technical solution selected as a prototype, designed to house the antenna equipment of radio and radio relay communication channels (see USSR author's certificate JN ⁇ > 459824, CL. H01Q 1/12, 1975).
  • the device should provide a stable directivity of antennas with a narrow diagram.
  • the known device consists of three masts of traditional construction (mast-trusses), having a common base and an antenna platform, hinged on the tops of all three masts. Side extensions are attached to the tops of each mast. For greater stability, the masts are connected on several levels with rigid horizontal articulated struts.
  • the main disadvantage of the known device is that it is not able to provide high angular stability of the position of the upper platform. This is due to the fact that the antenna platform is pivotally attached to the tops of the masts, and the horizontal struts to the lateral surfaces of the masts. Accordingly, the platform, masts and strut in the projection form a trapezoid, at the vertices of which there are hinges. From the course of geometry, it is known that the trapezoid is a rigid figure and under load it deforms like a solid body. That is, the well-known construction will be bent as a whole, just like a regular mast truss, but of a larger size.
  • Another disadvantage of the known device is that the braces are attached to each mast separately. All the stability of a known device is based on its symmetry. That is, all three masts are strictly single T RU2017 / 000446
  • the forces from the stretch marks may not be identical under wind load due to the fact that they were tensioned unevenly when the device was installed on the ground, or changed their condition from time to time, or from weather conditions (for example, icing, uneven heating due to the sun, wind) .
  • the horizontal projections of the forces acting on the masts will be partially aligned at the expense of the upper platform, but the vertical components of the forces on the part of the stretch marks will be different for each mast. They, in particular, will depend on wind load. This inconsistency will lead to the fact that with the wind the platform will tilt (change the elevation angle) or rotate in azimuth.
  • the known device has a complex structure and, accordingly, its complex installation takes place.
  • the technical result of the claimed invention consists in a substantial increase in the angular stability of the position of the upper platform of the mast with any wind loads and other negative natural factors acceptable in the area (icing, uneven solar heating, etc.) while simultaneously reducing the metal intensity construction and simplification of its assembly at the installation site.
  • a mast with an upper working platform stabilized in the direction including an upper working platform, vertical posts, horizontal struts, hingedly connected with vertical posts, and lateral extensions connected to the base, is achieved by the fact that the mast consists of two pairs of vertical racks, with both racks of each pair being hingedly connected by identical horizontal struts, and the pair of vertical stands, in turn, are interconnected by either hinged pairs of identical additional horizontal struts or pads hinged on the horizontal struts of pairs vertical racks.
  • the high stability of the position of the upper platform of the mast is achieved due to the fact that its entire structure consists of rectangles, which, as is well known, are not a rigid figure and, if there are hinges at the vertices, they are freely deformed into parallelograms, U2017 / 000446
  • both pivotal hinges and elastic hinges can be used as hinge joints.
  • the advantage of the swivel hinges is that the mast during transportation to the installation site can be folded into a more compact flat design. At the same time, the whole structure can be manufactured in the factory and at the assembly site only additional installation (to install horizontal struts or platforms) between pairs of vertical racks is necessary.
  • Vertical racks of the mast can be made of almost any type of rolled products, which makes the mast technologically simple and economically advantageous. It is most advisable to make racks from a metal pipe of round or rectangular cross section, from a channel bar or from an I-beam. These types of rolled products do not require additional mechanical treatment and have high torsion characteristics. It is known that the maximum torsional rigidity, with the same weight per meter, has a thin-walled round tube.
  • the vertical mast racks can be made of welded metal trusses.
  • the mast can be made of several uniformly mounted vertical sections, each vertical rack which is equipped with a connecting element. Therefore, there is not much point in developing a number of individual structures of a mast of various heights. You can simply increase the required height due to additional sections of the same type. In addition, these low sections are easier to transport to the installation site.
  • the mast racks can be made of reinforced concrete. These racks can be made directly at the installation site of the mast, delivering only the formwork, reinforcement and cement to the site.
  • the pouring of concrete can be carried out in removable or permanent formwork, for example, in a steel pipe.
  • removable formwork in the places of installation of horizontal struts, metal embedded plates are made.
  • permanent formwork in the form of a steel pipe, the installation of horizontal struts can be carried out directly to the steel pipe.
  • side stretch marks are installed on several levels of the mast height.
  • the claimed technical solution due to the presence of two pairs of vertical pillars forming rectangular stands and allowing them to be transformed under the action of wind loads into parallel patterns, allows stabilizing in the direction of the upper platform on which the equipment with rigid stabilization in angle is fixed, which It has no analogues among the known devices created to counteract the wind load on the mast, and, therefore, meets the criterion of "inventive level".
