Definitions
- the invention relates to means for joining concrete piles comprising a fixed end shoe on each of the adjacent pile ends, and elements for joining the piles at the end shoes, said elements including a number of guides opening at the outside of the pile, close to the adjacent pile ends, guides in one pile being located opposite to guides in the other pile, and locking members, spanning the joint between the piles, which are driven from the outside into guides located opposite to each other in the pile ends to press said ends together by wedge action between guides and locking members.
- Joining means of this type is described in the Swedish patent application 7201610-0.
- joining means of the type referred to is that such means can be easily mounted and permits the end shoe to form a completely flat end surface.
- the purpose of the invention is to construct the joining means in such a way that there can be provided and maintained a desired prestressing in the locking members, at the same time securing permanent engagement between the adjacent pile ends. It is also intended to provide safe latching of the locking members in the prestressed condition in the guides.
- FIG. 1 is a side view, partly a vertical sectional view, of the adjacent ends of two concrete piles joined by the joining means of the invention
- FIG. 2 is a fragmentary side view of the pile ends taken perpendicularly to the view in FIG. 1
- FIG. 3 is a side view of a guide in the joining means of the invention
- FIG. 4 is a vertical sectional view of the guide in
- FIG. 5 is a side view of a locking member in the joining means of the invention.
- FIG. 6 is an end view of the locking member shown in FIG. 5, and
- FIG. 7 is a perspective view of a latch member forming part of the joining means, to be located in the locking member for engagement into the guides co-operating with the locking member.
- FIGS. 1 and 2 in the drawings the upper and lower ends, respectively, of two concrete piles 10 to be joined together are disclosed.
- the piles have square cross-sectional shape, but as far as the invention is concerned they can have any cross-sectional form.
- Each pile has at the end thereof which is adjacent to the other pile, an end shoe 11 of metal sheet, which encloses the end portion of the concrete pile.
- This end shoe comprises a number of guides 12 attached by welding to the end shoe and moulded into the concrete pile.
- Each guide forms a T-shaped groove 13 which opens in the outside surface of the pile and extends perpendicularly to said surface into the pile.
- the guide is shown in more detail in FIGS. 3 and 4.
- T-shaped groove 14 for anchoring the guide to the pile by the end of a reinforcing" iron 15 embedded into the pile, being screwed into the blind hole as shown in FIG. 1.
- four guides are provided located in pairs at opposite sides of the pile, the guides in one pile end being opposite to the guides in the other pile end engaged therewith.
- the transverse portion of the T-shaped groove forms two abutment surfaces 16 for one flange 17 or the other of an I-shaped locking member 18 which is driven into two guides opposite to each other, to be received by one half in one guide and by one half in the other guide, spanning the joint between the two pile ends engaging each other.
- the abutment surfaces 16 are spaced from the pile end such that the locking member rather easily can be driven into the guides substantially to the midpoint thereof where the abutment surfaces at an inclined surface 19 including an angle of the order of 5 join an inner portion spaced a greater distance from the end surface of the pile.
- This distance is so great that the locking member when passing onto the inner portion of the abutment surfaces during the continued driving, will be exposed to a stretching of the order of 5?°, said stretching being substantially a plastic stretching, which implies, of course, that the locking member is made of a material allowing a great plastic stretching.
- blind hole 14 for the attachment of the reinforcing iron 15 is located substantially at the midpoint of that part of the abutment surfaces 16 in the guides 12, which is spaced the greater distance from the end surface of the pile, i.e. centrally of the portion of the locking member driven into the guides, which is exposed to plastic stretching. It is avoided by this arrangement that there will be produced in the pile a troublesome moment due to the pile ends being drawn together at the plastic stretching of the locking member.
- An advantage of the interengage ent of the pile ends effected by the locking member being plastically stretched is that the joining means can be manufactured without narrow tolerances being applied, because existing inaccuracies will be compensated for when using the joining means.
- a latch member 20 In order to latch reliably the locking member 18 when it is driven into the guides 12 there is provided a latch member 20, FIG. 7.
- This latch member comprises a steel sleeve having a cylindrical portion 21 and a conical portion 22, and said sleeve is slotted in the longitudinal direction thereof so that it can be resiliently compressed; the slot is shown at 23.
- the cylindrical portion 21 forms a sharp edge 24.
- the latch member is received in a rectangular recess 25 in the locking member, FIG. 5, the cylindrical portion of the latch member having such diameter that said portion projects slightly at the sides of the locking member, as will be seen from FIG. 6.
- the recess 25 is located at the midpoint vertically of the locking member closer to one end of said member than the other end thereof, viz.
- the latch member will be disposed centrally of the interface between the two adjacent pile ends when the locking member is being driven. When this is effected, the latch member will be compressed elastically, which is permitted by the slot 23, because the latch member is wider than the groove in the guide. Furthermore, the latch member will engage into the bounding surfaces of the groove at the sharp edge 24 if the locking member tends to move outwards from the groove in the guides, such movement of the locking member being effectively prevented thereby.
- a small chamfer as long as the latch member can be provided in the groove of each guide at the opening of the groove in the end surface of the pile as is shown at 26 in FIGS.
- latch member can expand under spring bias at this chamfer just as the locking .member has been completely driven into the groove. Then, the latch member will engage the edges of the chamfer if the locking member tends to move out of the groove, which provides a particularly effective latching of the locking member against such movement.
- a central latch member in each locking member there can be provided two such latch members for engagement eaoh with one of the two guides co-operating with the locking member.
- This member can be formed as a bow the limbs of which are connected with a pin and which is driven into the guides by hammering on the web.
- the pin will be received in the groove and accordingly will form the part that is exposed to the plastic stretching.
- the bow can be dispensed with and the pin can be provided with a central cross-head which projects from the pin so as to form the part on which one is hammering when driving the locking member.
- a central pin can be provided in a known manner in one pile end to engage a central hole in the other pile end when the pile ends are moved together.
