Definitions

  • the invention relates to an innovation in the manufacturing technology of support poles (or bars) of supports with lattice structure, such as support poles of telecommunication towers, transmission towers, support structures applied in photovoltaic power stations, trusses applied for stage machinery and other similar structures.
  • Trusses are support structures composed of straight bars or beams that under certain conditions are able to withstand external forces such that only compressive or tensile stresses occur in them, i.e., bending stresses are never present. The condition for this is that the bars are loaded exclusively at their points of connection, i.e., at the nodes of the structure.
  • Trusses can be found in many applications.
  • telecommunication towers are currently implemented applying such poles/chord bars that typically have base plates or end plates at their ends, with tabs adapted for receiving bars connected thereto being disposed at the circumferential surfaces of the poles/chord bars.
  • These structures are manufactured in prefabricated forms that ensure that the tabs for attaching further stiffening members are installed at their predetermined position and orientation, with the position of the base and end plates also being adjusted during this process.
  • Conventional tower structures typically consist of upwardly converging legs or bars that run parallel to each other along the top section, and webs or diagonals that connect them horizontally and transversely.
  • the present invention allows for positioning elements and components and retaining them in place without form or jig construction, thereby optimising the manufacturing process.
  • the document CN 113279488 discloses a node for interconnecting steel columns, which consists of a lower steel column (bar), an upper steel column (bar), an end plate of the lower column, a base plate of the upper column, and connectors disposed on the circumferential surfaces of the columns.
  • the objective of the present invention is to provide a pole that is able to eliminate the shortcomings of known tower configurations, and can be manufactured without a form, significantly reducing manufacturing time and costs.
  • the invention is based on the recognition that, based on the construction design of the tower, the poles -bars - can be prefabricated and preworked, so the position and orientation of the components connected to the tower base, such as the angle of inclination of the base component is clearly and unequivocally determined by the notches formed in the bar during the preworking process, so further stiffeners connecting to the bar can be installed quickly and accurately.
  • the objective according to the invention is accomplished by providing a pole that is characterised in that the pole comprises a bar (2) wherein the lower end and an upper end of the bar are provided with a respective horizontal base plate (6) fitted into respective notches (24, 25) located at the lower and upper end of the preworked bar, and wherein the bar is secured at an angle a with respect to the vertical direction, with further notches (8; 12; 17; 18; 28) for receiving connection members (7, 15) that are to be installed between the bars and are adapted for determining the position of and for securing horizontal connecting bars (3) and further stiffening bars (4) being formed in the circumferential surface of the bar (2) for constructing the tower.
  • the base member is a square plate provided with a centre bore and with chamfers (22), with seating tabs (24; 25) being formed along the centre bore, wherein the seating tabs of the base member preferably lie at an angle of 120° with respect to each other, and the seating tabs of the base member have a size of 20-50 mm.
  • connection member is formed of a leg (9) passing through the notch of the bar (2) and abutting against the chord bar and a head portion (7; 13) that is connected to the leg and is made integral therewith, the head portion being provided with bores (11; 16).
  • connection members (15) are secured by welding in the notch of the bar, the notches of the bar being formed by laser cutting.

  • the orientation of the connection member is determined by an orientation tab (27).
  • the horizontal connecting bars (3) can be secured at the node B by means of bores (16) located in the head portion (15).
  • a further notch (17) is formed in the bar (2) under the connection member (13) for receiving a connection member that provides the connection of a stiffening bar (4) of the tower.

  • Connection members (7) and (13) facilitating, respectively, the connection of horizontal connecting bars (3) and the stiffening bar (4) are located at point C under the base plate (6).
  • the base plate (6) is preferably a square-based plate having chamfered corners, i.e., with comers having chamfers (22).
  • the base plate (6) shown in Fig. 7 is a square-shape plate having chamfers (22), the base member may also have other shapes.
  • the seating tabs (19), (21), and (23) adapted to fit into the base member (6) have different sizes to enable the base plate (6) to be connected in a predetermined manner and direction, which can be determined based on the design of the truss structure to be produced, and on the preworking of the bar (2).
  • the base plate (6) comprises three seating tabs (19), (21), and (23), the size of the seating tabs being 20-50 mm and the tabs being disposed at an angle of 120° with respect to each other.

  • the orientation notches and the attachment notches have different widths; the base member (6) can thus be prevented from being installed in an incorrect position.
  • the base plate (6) can thus be placed on the bar (2) only with a predetermined orientation, either for supporting the structure on the ground or for connecting the bar (2) of the subsequent segment of the tower.
  • the tower to be constructed has vertical legs - i.e., its legs have no inclination angle - the notches made during preworking the bar (2) have identical depth, but the notches will still have different widths because that is important for positioning.

If the legs must be positioned at an angle with respect to the ground (90-a°), the notches have different depths, and the plane of the cutting depth extends at an angle a relative to the plane perpendicular to the axis of the bar (2).
  • cutting depth is the smallest in the case of the orienting notches pointing towards the centre of the tower, the depth increasing in the direction of the attachment notches.
