  • piles are known, used as construction elements used for anchoring structures, allowing loads to be transferred to a resistant soil layer when they are located at a depth such that conventional foundation footings or slabs are rendered technically or economically unfeasible.
  • British Patent GB2360809 relates to a pile and an installation method, disclosing a pile that comprises a rod having at least one helix acting as a screw thread to facilitate the penetration of the rod into the ground, where the helix has a plough-shaped load flank for compressing the ground radially outwards during penetration of the rod.
  • the pile introduction process comprises the incorporation of a bonding agent around the rod during introduction for insertion into a vacuum created by the plough-shaped assembly.
  • British Patent GB2397327 relates to a pile comprising at least two portions axially aligned telescopically in order to fix the effective pile length and comprises fixing means for allowing one of the sections to be fixed to another section in a plurality of positions to selectively determine the total length of the pile.
  • the problem posed consists of defining means for fixing solar collector structures to foundation piles allowing execution of the fixation in a simple and highly accurate manner.
  • the present invention describes, according to a first aspect, a device for laying the foundations of a support structure for solar collectors comprising:
  • the joining means for joining the pile to the structure comprise a bolt, attached to the pile by a lower end of the bolt (threaded or not threaded) and attachable to the structure by a threaded upper end opposite the lower end.
  • the lower end of the bolt is, according to this first embodiment, housed and fixed in a body inserted in the second end of the pile (the end projecting from the ground) and fixed to said pile.
  • the body is made of hardenable material susceptible of, by drying and/or setting, hardening and adhering to the pile and bolt, such as, for example, cement, concrete or mortar.
  • a second aspect of the invention relates to a method for anchoring a support structure for solar collectors to the ground, using the device of the invention, which comprises the following steps:
  • the method can include the additional step of fixing the bolt to the pile.
  • the bolt can be fixed to the pile following the steps below:
  • defining a receptacle on the second end of the pile comprises forcibly introducing, to a certain depth, a first watertight elastic plug, preferably of polystyrene foam, having dimensions slightly larger than the cross-section of the second end of the pile, said receptacle being composed of the first plug and by the inner surface of the second end of the pile, above the first plug.
  • a first watertight elastic plug preferably of polystyrene foam
  • the step that involves defining the receptacle may include an additional stage of forcibly introducing to a second depth, less than the first depth, a second watertight elastic plug, preferably of polystyrene foam, having dimensions slightly larger than the cross-section of the second end of the pile, said second plug having a first opening for inserting the bolt and a second opening for pouring the hardenable material.
  • the location of the first opening can be established preferably using templates or topographic control.
  • the joining means comprise, alternatively to the bolt, a plug disposed tightly around the exterior of the second end of the pile, said plug having first fixing means for fixing the pile to the structure.
  • the fixing means comprise a metal bracket having a first side for fixation to the plug and a second side for fixation to the structure. The second side can also be fixed to the structure using bolts or other types of fasteners.
  • the joining means comprise, in addition to a bolt:
  • the first slots and the second slots comprise:
  • the fixation of the bolt comprises the following steps:
  • the joining means may additionally comprise a joining element, preferably a profile, having a flat face, wherein said flat face comprises bores to facilitate the fixation of the piles to the structure, said flat face being adapted for the structure to rest on said flat face.
  • the method explained comprises the additional step of determining the location of the pile with respect to the ground prior to the introduction of said pile in the ground, as well as determining the location, if using bolts, of the bolt with respect to the pile prior to fixing the bolt to the pile.
  • the location of the bolt and/or pile shall be determined preferably using one of the following techniques:
  • the present invention allows anchoring of a support structure for solar collectors to the ground in a fast, accurate and cost-effective manner, simply and cleanly, without need for passage of trucks, cement mixers, etc.
  • FIG. 1 shows a sectional view of the device in accordance with the first preferred embodiment.
  • FIG. 2 shows a view of the device in accordance with the second preferred embodiment.
  • FIG. 3 a shows a perspective view of the first plate in accordance with the third preferred embodiment.
  • FIG. 3 b shows a perspective view of the second plate of the third preferred embodiment.
  • FIG. 3 c shows a perspective view of the first plate and the second plate joined together in accordance with the third preferred embodiment.
  • FIG. 3 d shows a side view of the joint between the first plate and the second plate.
  • FIG. 4 a shows a view of an example of a joint between the pile and the structure by means of a profile.
  • FIG. 4 b shows a detailed view of the joint by means of a profile of FIG. 4 a.
  • the device for anchoring a support structure ( 2 ) for solar collectors to the ground ( 1 ), in accordance with the invention, comprises: at least one pile ( 3 ) having a first end ( 4 ) adapted for insertion into the ground ( 1 ) and a second end ( 5 ) projecting from the ground ( 1 ); and joining means for joining the pile ( 3 ) to the structure ( 2 ).
  • the method for anchoring a support structure ( 2 ) for solar collectors to the ground ( 1 ) using the device of the invention which comprises the following steps: introduction of the first end ( 4 ) of the pile ( 3 ) in the ground ( 1 ), leaving the second end ( 5 ) above the ground ( 1 ); and fixation of the structure ( 2 ) to the bolt ( 7 ).
  • the joining means for joining the pile ( 3 ) to the structure ( 2 ) comprise a bolt ( 7 ) attached to the pile ( 3 ) by a lower end ( 8 ) (threaded or not threaded) and attachable to the structure ( 2 ) by an upper end ( 9 ) threaded opposite the lower end ( 8 ).
  • the method comprises the previous step of fixing the bolt to the pile.
  • the lower end ( 8 ) of the bolt ( 7 ) is housed in a body ( 10 ), formed by mortar, inserted in the second end ( 5 ) of the pile ( 3 ) and fixed to said pile ( 3 ).
  • the bolt ( 7 ) can be fixed to the pile ( 3 ) by forcibly and consecutively introducing, prior to the bolt ( 7 ), through the second end ( 5 ) of the pile ( 3 ), a first watertight plug ( 13 ) and a second watertight plug ( 14 ), preferably of polystyrene foam, having dimensions slightly larger than those of the cross-section of the second end ( 5 ) of the pile ( 3 ), defining a receptacle (not shown) between the two plugs.
  • a second opening ( 12 ) and a first opening (not shown) are made in the second plug ( 14 ) and the mortar is poured into the receptacle through the second opening ( 12 ), allowing said mortar to harden.
  • the location of the first opening is determined preferably using a template or topographic control.
