    After distributing evenly on the bottom plate of the pile and thereby on the pile tube. The properties of steel used in pile pipes have improved as steel qualities have developed and the load-bearing capacity has risen. Due to this, the capacity of existing mountain shoes is not enough in any case. The load-bearing capacity of the rock shoe can be improved without increasing the blank thicknesses of the tip by changing its structure so that it better distributes the loads. The diameters of the large piles are of the class 600-1200 mm and the mass of the tip plate is very large, which is why the increase in blank thicknesses increases the mass since before and makes the rock shoe very heavy and increases the material costs.
    Brief description of the invention The object of the invention is to provide a pile, which comprises a mountain shoe, and a mountain shoe which is to be connected to the pile, so that the above-mentioned problems according to prior art can be solved. The object of the invention is achieved with a pile according to the characterizing part of claim 1 and a mountain shoe for pile according to the characterizing part of claim 7.
    Advantageous embodiments of the invention are the subject matter of the dependent claims.
    The invention is based on providing a pile provided with a new kind of mountain shoe. The mountain shoe comprises a bottom plate, a tip pin and stiffening plates extending from the bottom plate. In accordance with the invention, the tip pin of the pile's mountain shoe does not extend all the way to the base plate, but remains at a distance X from it. In other words, the lower surface of the base plate is at a distance X from the upper surface of the tip pin. Two or more stiffening plates have been mounted between the tip pin and the bottom plate. The purpose of the stiffening plates is to transfer loads and loads evenly on the bottom plate and thereby on the pile pipe. The stiffening plates are mounted to extend between the bottom plate and the tip pin to attach the tip pin to the bottom plate, so that between the lower surface of the bottom plate and the upper surface of the tip pin becomes an empty space or an empty space. In this case, the tip pin is attached to the bottom plate by means of two or more stiffening plates, which extend between the bottom plate and the tip pin. In one embodiment, the stiffening plates next to the base plate of the pile comprise two claws and a straight or curved section joining them.
    The advantage of the invention is that with the help of the structure of the rock shoe material savings are achieved compared with a situation that a tip of the current model would be strengthened by increasing the blank thickness. With the aid of the pile and rock shoe according to the invention according to the invention, stresses / loads during installation can be distributed more advantageously, whereby a better resistance to loads and loads during and after installation is achieved without increasing the blank thicknesses. In this case, the loads directed towards the rock shoe can be distributed more advantageously on the bottom plate, whereby the tip structure of the pile can withstand the increased pile loads and loads during installation.
    Brief Description of the Figures The invention will now be explained in more detail in connection with preferred embodiments, with reference to the accompanying drawings, of which: Figure 1 shows a mountain shoe for a pile according to the prior art; and figure 2 shows a schematic principle view of the structure of the mountain shoe according to the invention.

In accordance with Figure 1, the tip pin 22 of the pile passes through the tip all the way to the bottom plate 23, in which it is fixed by welding.
    The triangular stiffening plates 24 are welded to the tip pin 22 and the base plate 23. The stiffening plates 24 are attached to the lower surface 23 of the bottom plate 23 in the prior art, from which they extend downwards and are further attached directly to the outer surface or outer jacket 1 of the tip pin 22, as shown in Figure 1. The function of the stiffening plates 24 is to support the tip pin against loads during the installation of the pile. In an alternative rock shoe according to the prior art, the rock shoe comprises a separate sleeve part, which is located at the location of the tip pin 22 for the rock shoe according to Figure 1 and the stiffening plates 24 extend from the lower surface of the bottom plate 23 to the outer surface or outer shell of the sleeve part.
    The sleeve part extends through the rock shoe all the way to the bottom plate 23 and its lower surface. The sleeve part further comprises at its lower end an opening for receiving a separate tip pin. In other words, such a solution corresponds to the solution according to Figure 1, with the difference that the tip pin 22 in Figure 1 is replaced by a sleeve part which receives a separate mountain shoe.
    Figure 2 shows a part of a pile according to the present invention, in particular a steel pile, and a mountain shoe 5 for a pile according to an embodiment of the invention. The rocker shoe 5 comprises a tip pin 2, a bottom plate 3 and stiffening plates 4. According to Figure 2, the tip pin 2 of the pile does not extend all the way to the bottom plate 3. The upper surface 8 of the tip pin 2 is at a distance X from the lower surface 3 of the bottom plate 3. The distance X is preferably about 1/3 of the diameter of the pile.
    Large piles have a diameter of about 600-1200 mm, so X is preferably 200-400 mm. Between the tip pin 2 and the bottom plate 3, two or more stiffening plates 4 have been mounted in accordance with Figure 2. The stiffening plates 4 transfer loads and loads from the tip pin 2 evenly to the bottom plate 3 and thereby to the pile pipe. The stiffening plates 4 are mounted to extend between the bottom plate 3 and the tip pin 2, so that between the lower surface of the bottom plate 3 and the upper surface 8 of the tip pin 2 becomes an empty space or an empty space, as shown in Figure 2. In other words, the tip pin 2 connected to the bottom plate 3 only by means of the stiffening plates 4. The stiffening plates 4 are fixed, for example by welding, in the lower surface of the bottom plate 3 and they extend from it downwards towards the tip pin 2. The lower end of the stiffening plates 4 is further fixed, for example by welding, in the tip pin 2. In the embodiment in Figure 2, the stiffening plates 4 are fixed both in the upper surface 8 of the tip pin 2 and in the side surface or jacket 9 of the tip pin, so that the upper surface 8 of the tip pin is at the above-mentioned distance from the bottom plate 3 lower surface and between the upper surface 8 of the tip pin 2 and the bottom plate 3 becomes an empty room or an empty space.
    According to Figure 2, the bottom plate 3 extends substantially to the area of the entire cross-section of the pile tube 1 and is according to a preferred embodiment of the same size as the outer diameter of the cross-section of the pile tube. The bottom plate 3 is fixed in the pile pipe, preferably by welding. Preferably, the steel piles are made of a tube with a circular cross-section.
    In one embodiment, the stiffening plates next to the bottom plate 3 of the pile comprise two claws 11 and a straight or curved section 10 which joins them. in the embodiment according to figure 2 there are two or more stiffening plates 4 of metal, according to a preferred embodiment three. The stiffening plates 4 preferably comprise next to the base plate 3 of the pile two claws 11 and a straight or curved section 10 which joins them. According to one embodiment, the stiffening plates have been provided by one piece and bent from one piece to their shape and welded to the bottom plate 3. According to a second preferred embodiment, the stiffening plates 4 are provided by two or more separate pieces, such as a straight plate.
    In this case, the stiffening plates 4 have been formed by welding together two or more disc-shaped parts and attaching the formed stiffening plates 4 to the base plate 3. In the preferred embodiment the ends 11 of the claws 11 of the stiffening plates 4 are as close as possible to the base plate 3 or to the stiffening plate. 4 straight / curved sections 10 are as close to the center point 3 of the base plate as possible, or in the center point. According to Figure 2, the stiffening plates 4 have been provided as curved plates, such as substantially in U- or V-shape, which open towards the periphery of the bottom plate 3 and the section joining their claws 11 being close to the center of the bottom plate 3. In the embodiment of Figure 2, the stiffening plates 4 have furthermore been made conical, so that they taper off or their claws 11 become shorter from the bottom plate 3 towards the tip pin 2.
    According to a preferred embodiment, cuts 7 have been machined in the straight / curved sections 10 of the stiffening plates 4. The upper surface 8 of the tip pin 2 is placed next to the cuts 7 in the stiffening plates 4 and thanks to the cuts 7 the tip pin 2 can be fixed by welding firmly in the stiffening plates 4 from the top tip. surface 8 and from the jacket part 9.
