Definitions

  • the present invention concerns a pile connecting structure, more specifically a pile connecting structure of high workability capable of connecting upper pile and lower pile to each other simply and accurately.
  • the objective of the present invention realized in view of various problems with said conventional pile connecting structures, is to provide a pile connecting structure of high workability capable of simply and accurately connecting the upper and lower piles to each other, and preventing the pile diameter from becoming large, even at the connection portion.
  • the pile connecting structure according to the present invention is a pile connecting structure for connecting upper and lower piles to each other by interposing a connecting plate of approximately the same diameter as the piles at the connection portion between the upper and lower piles, characterized in that the end plate on either one of the upper or lower piles and the connecting plate are fixed by screwing bolts inserted into circular-shaped bolt insertion holes formed on the connecting plate to the end plate of the pile on one side, and the end plate of the other pile and the connecting plate are fixed in the state where the heads of the bolts screwed to the pile on the other side is inserted into the large diameter portion of the heteromorphic bolt insertion holes communicating between a large diameter portion which the heads of the bolts formed on the connecting plate can pass through, and a small diameter portion which the heads of the bolts cannot pass through, by making the other pile and the connecting plate move in a relative fashion so that the bolts may shift from the large diameter portion of the heteromorphic bolt insertion holes to the small diameter portion.
  • This pile connecting structure is capable of fixing, in a pile connecting structure for connecting upper and lower piles to each other, the end plates of the upper and lower piles and the respective connecting plates to each other by bolting, and by interposing a connecting plate of approximately the same diameter as the piles at the connecting portion between the upper and lower piles, thus quickly enabling the establishment of a connection between the upper and lower piles at low cost, without having any influence on pile length thanks to the comparatively small thickness of the connecting portion, and further enabling the burying of piles in the ground without presenting any obstacle to the pile driving work, thanks to the absence of any projections at the outer circumference of the piles.
  • a cylindrical body is integrally disposed in which the end of the upper and lower piles may be inserted.
  • an operating port for fastening, from the outer circumferential side of the connecting plate, the bolts shifted from the large diameter portion of the heteromorphic bolt insertion holes to the small diameter portion.
  • the connecting plate may be formed by being split into a plurality of pieces.
  • auxiliary member having a threaded hole different from that of the connecting plate, so that the pile connecting bolts may be screwed into that auxiliary member.
  • projections in the shape of bolts may be provided in a way that they can be fixed to either the end parts of the piles or the auxiliary members.
  • Fig. 1 to Fig. 2 indicate the first embodiment of the pile connecting structure according to the present invention.
  • This pile connecting structure is a pile connecting structure for connecting an upper pile 1 and a lower pile 3 to each other, by interposing a connecting plate 5 of about the same diameter as the piles, at the connecting portion between the upper pile 1 and the lower pile 3, wherein the end plate 4 of either one of the upper pile 1 or lower pile 3, lower pile 3 in this embodiment, and the connecting plate 5 are fixed by screwing bolts 6 inserted in circular bolt inserting holes 51 formed on the connecting plate 5 to the bolt holes 41 in the end plate 4 of the lower pile 3, and the end plate 2 of the other pile, upper pile 1 in this embodiment, and the connecting plate 5 are fixed, in the state in which the head 71 of the bolts 7 screwed to the end plate 2 of the upper pile 1 is inserted in the large diameter portion 52d of heteromorphic bolt insertion holes 52 communicating between a large diameter portion 52d which the head 71 of the bolts 7 formed on the connecting plate 5 can pass through and a small diameter portion 52c which the head 71 of the bolts 7 cannot pass through, by making the upper pile 1
  • the piles to which can be applied this pile connecting structure are concrete piles such as prestressed concrete piles, etc., steel piles, SC piles, and composite piles such as PRC piles, etc. provided with end plate at the end, though not particularly restricted to them. Explanation will be given below by taking an example of prestressed concrete piles.
  • the upper pile 1 and lower pile 3 consisting of prestressed concrete piles have end plates 2, 4 disposed at their end, and in these end plates 2, 4 are formed bolt holes 21, 41 which were used for introducing prestressed (concrete) when manufacturing prestressed concrete piles. Those bolt holes 21, 41 are utilized in this embodiment.

  • the bolt insertion hole 52 may be all right to construct (the bolt insertion hole 52) in a way to either make the bolt 7, the head 71 of which is inserted in the large diameter portion 52d of the heteromorphic bolt insertion hole 52, turn in the fastening direction, when shifting it from the large diameter portion 52d to the small diameter portion 52c of the heteromorphic bolt insertion hole 52, with the difference in contact resistance between the bolt seating face 52b and the head 71 of the bolt 7 [To make the contact resistance between the bolt seating face 52b on the outer circumference side of the connecting plate 5 and the head 71 of the bolt 7 larger than that on the inner circumference side of the connecting plate 5 (case where the bolt 7 is right threaded, in this embodiment) (or smaller (case where the bolt 7 is left threaded, in this embodiment)), either perform surface treatment to the bolt seating face 52b, or dispose a member increasing the contact resistance such as soft metal plate such as aluminium, etc.
  • Fig. 2 (A) install the lower pile 3 in a pile hole dug in the ground and, in the state in which the lower pile 3 is provisionally fixed so that the lower pile 3 may not make any up-down movement or turn, when the end plate 4 disposed at the end part of the lower pile 3 reached a prescribed position from the ground such as a height easy for execution of work by workers on the ground, for example, though not particularly restricted to it, place the connecting plate 5 concentrically on the end plate 4 of the lower pile 3, make the bolt hole 41 formed in the end plate 4 agree with the bolt insertion hole 51 in the connecting plate 5, insert the bolt 6 in the bolt insertion hole 51, and fit the bolt 6 in the bolt hole 41 by screwing, by using a box wrench (not illustrated).
  • the fixing work of the end plate 4 of the lower pile 3 and the connecting plate 5 may be performed before the lower pile 3 is installed in the pile hole.
  • the upper pile 1 and the lower pile 3 can be fixed with the bolt 6 and the bolt 7 respectively, by interposing one piece of connecting plate 5 at the connecting portion between the two, enabling to perform the connection between upper pile 1 and lower pile 3 quickly and at low cost, without having any influence on the pile length because the thickness of the connecting portion can be kept comparatively small.
  • absence of any projection at the outer circumference of the piles makes it possible to bury the piles in the ground without putting any obstacle to the pile driving work, and execute the piles with high reliability and accuracy and efficiently.
