Definitions

  • the system of the invention has the object of lifting large structures, which have previously been completely assembled on the ground, until placing them in their final position, eliminating assembly operations at heights, thus preventing the risks involved with them and reducing the assembly time for both the structure and for the total construction of the building such structure pertains to.
  • the corresponding structure is hoisted, it is then placed on the permanent props or supports thereof, which could have been previously assembled, during or after the construction of the structure itself, and the mechanisms used for lifting it are then disassembled and removed.
  • the lifting device described in this patent is limited to small-sized roofs or structures.
  • the system of the invention is designed to achieve a fast and safe operation for lifting large-sized structures, allowing the complete assembly of the structure on the ground. Working at heights, which is always more complicated and dangerous, is thus eliminated.
  • the system is made up of a series of lifting columns, which are suited in number and position to the size of the structure to be hoisted, connected to a control system allowing a joint, controlled and synchronized operation of all the columns for lifting the entire structure step-by-step up to its final position.
  • Each of the lifting columns comprises the following elements:
  • the sliding ring climbs up, step-by-step, being anchored respectively in the fixed column and in the moving column, until reaching the calculated and expected position for the structure.
  • the electronic control system allowing the synchronized operation of all the columns, coordinates the movements of the pneumatic thrust systems causing the vertical displacement of the moving columns of each lifting column, as well as the synchronized activation and deactivation of the pneumatic thrust and retention cylinders of all the sliding rings.
  • a lateral guiding system for the structure to be hoisted can optionally be assembled which is formed by one or more bearing towers collaborating in the absorption of horizontal stress due, for example, to wind loads, and thus preventing the lateral displacement of the structure during the hoisting operation.
  • the number of columns required for lifting it must first be calculated, then such columns are sized and the pressures of each of the hydraulic cylinders of the sliding rings of each column are then calculated.
  • the columns are completely assembled, comprising the assembly of the fixed columns, of the moving columns intercalated between them, of the pneumatic thrust systems of the moving columns and of the sliding rings, with their corresponding interlocking systems including, where required, the lateral guiding system to prevent lateral displacements of the structure during the hoisting operation.
  • the structure to be lifted is then anchored to the sliding rings of each of the columns.
  • the complete lifting of the structure occurs by repeating a lifting cycle by means of which the structure is lifted a height equivalent to the distance or spacing existing between two consecutive holes of the sections forming the fixed and moving columns, or a multiple of the distance between holes, which cycle comprises the following steps:
  • the system is made up of a series of lifting columns (1) duly distributed, in number, position and dimensions, according to the size of the structure (2) to be hoisted which allow, as can be seen in the Figures 4 , 5 and 6 , the simultaneous and controlled lifting of the entire structure (2) previously assembled on the ground.
  • all the lifting columns are connected together by means of an electronic control system for controlling all the pneumatic elements as well as the movement and position of each of the columns so that the lifting occurs with a height position difference that is less than a predetermined value which has previously been programmed into the control system.
  • This valor will represent the maximum deviation considered allowable among the columns during the entire structure lifting process. By way of example, it can be approximately 10 mm.
  • the lifting process occurs slowly and step-by-step, all the system parameters being controlled at all times, but completely hoisting the structure in a few hours, such that the complete assembly of the structure is carried out in less time and at a lower cost than with traditional processes, further minimizing the risk to the operators since the assembly is done on the ground and lifting it is done automatically by means of the control system.
  • Each of the lifting columns (1) is made up of a fixed column (3) and a moving column (4) which are assembled such that they are intercalated with one another, such that the moving column (4) can be displaced according to an up and down movement with regard to the fixed column (3).
  • Figures 7 to 12 show a specific embodiment for the lifting column (1) in which the fixed column (3) is made up of four metal sections (5) joined together through secondary beams (6), forming an integral assembly.
  • the moving column (4) is also made up of four metal sections (7) joined together through secondary beams (8) forming a second integral assembly.
  • Each fixed column (3) and moving column (4) incorporates several groups of secondary beams (6), (8), arranged at different heights which are spaced from one another a distance that is greater than the spacing or height that the structure is lifted in each lifting cycle to prevent interferences between the fixed column (3) and the moving column (4) in the vertical up and down displacements of the moving column (4).
  • the fixed column (3) is anchored to a structure or bearing base (9), fixed to the ground, while the moving column (4), intercalated with the fixed column (3), is borne on a thrust plate (10) under which a pneumatic thrust system (11) is assembled which is responsible for causing the up and down displacement of the moving column (4).
  • the pneumatic thrust system (11) is preferably formed by means of two horizontal flat plates, a lower fixed plate and an upper moving plate, on the perimeter of which the ends of an elastic annular belt are fitted, fixing them with respective flanges, thus forming a leak-tight elastic chamber, such that as gas under pressure is introduced in said chamber, the upper plate is lifted which in turn pushes and displaces the moving column (4).
  • the pneumatic system can be formed, in a simplified manner, from an air cushion.
  • Each column also incorporates a sliding ring (12), which is assembled such that it externally encircles the fixed column (3) and the moving column (4), and withstands the weight of the space frame (2) to be hoisted through anchoring means (17).
  • the sliding ring (11) incorporates an interlocking system (13) allowing it to be connected to the fixed column (3) and to the moving column (4), such that when it is connected to the moving column (4) it can be displaced with said column in its upwards movement with regard to the fixed column (3).
  • the interlocking system (13) comprises thrust cylinders (13') actuating thrust bolts (14') which are provided to be anchored in holes (15) of the moving column (4), and retention cylinders (13") actuating retention bolts (14") which are interlocked in holes (15) of the fixed column (3), allowing, as will be described below, the lifting of the sliding ring (12) with regard to the column (1) and, accordingly, of the structure (2).
  • the structure (2) is joined to the sliding ring (12) through anchoring means formed, either by means which work under pulling, such as high-strength cables, chains or stays (17), or by means of thrust sections, which anchoring means (17) are joined to the sliding ring (12) with the cooperation of hydraulic cylinders (18), which are communicated together and with the control system for regulating the stress of the anchoring elements (17) of each of the lifting columns (1).
  • the sliding ring (12) also incorporates a series of rollers (19) resting on the fixed column (3) and moving column (4), so as to allow the guided displacement of the ring (12) in its up and down movements.
  • the system also comprises guiding rings (20), arranged in the upper and lower part of each column (1), anchored to the fixed column (3) and provided with bearing rollers (21), required by thrust springs, on which the moving column (4) is borne, allowing its vertical up and down displacement in a guided manner.
  • the system can also incorporate guiding means in the central area of the columns when the height thereof requires it.
  • This system comprises extensible rings (22), connected together and to the sliding ring (12), such that as the sliding ring moves upwards, the extensible rings (22) are positioned along the column, as can be seen in Figure 11 .
  • These rings can be similar to the guiding rings provided in the upper and lower part of the column.
  • the lifting of the sliding ring (12), and accordingly of the structure, with regard to the columns (1) is carried out by repeating a lifting cycle comprising the following operative steps:
  • the assembly of the actuations of the lifting columns is connected forming a pneumatic network fed by one or several compressors, all of its components, i.e. filters, electrovalves and pumps, being connected through a programmable electronic control system.
  • the lifting columns are also joined by means of an electronic network controlled through a second programmable electronic control system which all the other subsystems of the lifting system depend on such that all the movements of the lifting columns are programmed and controlled to achieve a coordinated actuation of all the movements allowing the hoisting of the structure with very low tolerances between all its points.
  • control boxes are used for the control system of each lifting column, one of them in each ring for the control and synchronized activation/deactivation of the electrovalves and other elements for actuating the assembly of hydraulic cylinders (18) for regulating the anchoring means (17) of the structure and another one being located at the base of each column and distributing and controlling the actuations of the pneumatic thrust system (11) and the assembly of retention cylinders (13") and thrust cylinders (13').
  • the structure lifting and assembly process would have at least the following operative steps of the lifting system, shown in Figures 1 to 6 :
