Description

DESCRIPTION

IN-LINE CONNECTION FOR PILES

OBJECT OF THE INVENTION

The present invention refers to the in-line connection for piles, which makes it possible to join precast piles to generate a longer pile.

BACKGROUND OF THE INVENTION

At present, in construction piling, when long lengths of piles are required, what is done is to insert shorter, precast piles, which are joined together in line to obtain a longer one.

This in-line connection for piles is currently materialized by means of corresponding tongue-and-groove joints (that is, they are coupled together), materialized in the ends of the piles to be joined, arranging transversal locking pins for the males in the inserted position. in the females of the tongue and groove.

In order to insert the dowels, the piles have on their lateral faces, in their end zone, some perforations that lead to the females of the tongue and grooves, in a position that coincides with some holes in the males, so that inserting the dowel through these perforations, it is covering the holes of the males and the perforations of the pile, blocking each male inside the female.

The insertion of the dowel is done by hand, with a mallet, and as many dowels must be inserted as there are male and female joints arranged for the tongue and groove of the in-line connection, which slows down the work, is dangerous due to the high weight of the piles and can cause breakage in parts.

DESCRIPTION OF THE INVENTION

The in-line connection for piles of the invention is of the type that includes corresponding tongue and groove joints in the ends of the piles to be joined, with dowels. locking of the males in the inserted position in the females of the tongue and groove; where according to the invention, the pins comprise retractable pivots with a spring to recover the protruding position, arranged transversely on the males in positional coincidence with some lateral recesses made on the females.

In this way, the pivots are retracted, during the insertion of the male into the female, for example automatically by means of ramps made in one or both of them so that when sliding when forcing the introduction, the retraction of the pivot is forced, and once the position of positional coincidence has been reached with the lateral recesses made in the females, they are extended and interlocked in them, making the necessary retention so that the tongue and groove is blocked and the piles joined in line with each other.

BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

The inline connection (1) for piles (2) of the invention is of the type that includes corresponding tongue and groove grooves (3) in the ends of the piles (2) to be joined, with locking pins of the males (5) in the position inserted in the females (6) of the tongue and groove, where according to the invention, the pins comprise retractable pivots (7) with spring (8) for recovery of the protruding position, arranged transversally in the males (5) in positional coincidence with some lateral recesses (66) made in the females (6) (see figs. 2 to 5), which in this case are interns.

Preferably, the cores (5) have a cylindrical shape, due to their easy machining, and include transverse housings (50) (see fig. 5) for the retractable pivots (7) and their recoil springs (8). For their part, the females (6) comprise some bushings (60) (see figs. 2 to 4) correspondingly hollow, that is, of the same shape and slightly larger dimensions to allow the insertion of the male into the female, in whose contour the lateral recesses (66) are materialized. In this way, with simple turnings all the pieces can be obtained. In addition, ideally the cores (5) and the bushings (60) will comprise rods (9) that can be embedded in the mass of the pile (2) in order to be firmly anchored therein. For this, it is preferred that the males (5) and the bushings (60) include some threads (11), which allows the detachable connection of said rods (9).

Likewise, it is preferred (see fig. 5) that the transversal housings (50) have a section with a larger section (51) and a section with a smaller section (52); the pivot (7) having a section of the same shape and smaller dimensions than that of the section with the smallest section (52) of the transversal housing and an internal end wing (70) with dimensions greater than the smallest section (52) of the housing (50). and smaller than the largest section (52) of the housing (50) to configure a stop for the output of the pivot (7) without further implementation. In this case, the spring (8) will be arranged between the end wing (70) and a cap (55) for closing the larger section (51) of the transverse housing (50).

Furthermore, preferably the cores (5) will comprise a first bevel (57) or rounded at its tip, and/or the pins (7) a second bevel (77) or rounded at its tip, to facilitate their insertion/penetration. In the case of the pivots, they can also be ramps in the direction of insertion.

Additionally, it is preferred that the joint comprise (see fig. 1) a plate (10) corresponding to the shape of the end of each pile (2), in which the males (5) and bushings (60) are mounted. giving body to the assembly and facilitating its placement during the molding of the pile. Said plate (10) ideally comprises a skirt (12) overlapping at the end of the corresponding pile (2).

Having sufficiently described the nature of the invention, as well as the manner of carrying it out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
