Description

Pole support structure Background of the invention The invention is related to the pole support structure and especially to the support structure of the electricity pole.

Forming the support structure of the column is typically difficult and laborious. For example, you often have to dig a big hole for the foundation. The work may require large machines, which are expensive to use and difficult to use, for example, in soft terrain.

Brief description of the invention The aim of the invention is therefore to develop a new column support structure. The column support structure according to the invention is characterized by what is said in the independent protection requirement. Some embodiments of the invention are the subject of independent protection claims. In the presented solution, the support structure of the column includes a foundation. The foundation of the column includes at least one anchor pile and a casting box to be fitted to the upper end of that at least one anchor pile. The casting box has a base and walls. When forming the foundation of the column, the casting box is filled with concrete. In this case, at least one anchor pile is fitted through the bottom of the casting box. Next, the column attachment is fitted to the casting box. The casting box is made of insulating material. Forming the foundation of such a column does not require digging a large pit. Furthermore, by using anchor piles, it is possible to avoid mass exchange, for example. Forming the foundation is possible using quite small machines, which is overall cost-effective and especially useful in connection with soft soils. All in all, the individual parts of the base unit N 25 are quite light. The advantage of a casting box made of insulating material is that the concrete is very easily and effectively insulated from the soil. Thanks to insulation 2, the concrete does not conduct cold to the soil. Furthermore, the anchor piles are not exposed to corrosion, because they stay inside the ground and concrete. = According to one embodiment, when forming the foundation, the casting N 30 box is filled with fiber concrete. This way, there is no need for separate concrete reinforcement inside the casting box. In this case, the structure of the foundation is quite simple. S According to one embodiment, the foundation also includes a horizontal insulating plate to be fitted around the casting box. The horizontal insulation board around the casting box effectively prevents the effect of frost on the foundation.

According to one embodiment, the casting box is a prefabricated module. In this case, the casting box is reliably the right size and structure, and there is no need to measure and manufacture the casting box at the construction site for each site.

According to one embodiment, the casting box is formed from insulation boards so that the casting box can be assembled on the construction site. In this case, the insulation boards that make up the casting box are easy to transport to the site, and the casting box is, however, easy to assemble from ready-made insulation boards that have been formed to fit in advance.

According to one embodiment, the at least one anchor pile in question is filled with concrete. In this case, the anchor pile gets corrosion protection on the inside.

In addition, concrete gives the anchor pile additional stiffness, so the size of the anchor pile can be reasonably small.

According to one embodiment, the insulating material of the casting box is extruded polystyrene. Such a casting box is sturdy, easy to handle and effectively isolates the concrete from the soil.

According to one embodiment, the support structure further comprises at least one ridge. By using a screed, the foundation can be reasonably simple and lightweight.

According to one embodiment, the harrow has a harrow bar with means for adjusting the harrow bar to the soil by twisting it. In this way, fitting the harrow's harrow bar to the soil can be done simply and the harrow bar stays securely in place while it supports the post.

According to one embodiment, the means for fitting the fork rod into the soil comprise a spiral blade fitted to the lower end of the fork rod. Such a structure is simple and easy to form. The spiral wing at the lower end of the fork rod keeps the fork rod effectively in place in the soil.

N According to one embodiment, there is a cross-directional pin in connection with the AN screw wing fitted to the lower end of the fork rod, in which case the fork rod can be screwed into the ground with a mounting rod, the lower end of which has a hook 3 that can be fitted to the pin. In this case, the rotational force rotating the fork rod can be directed N 30 to the lower part of the fork rod with the mounting rod, so the fork rod itself does not have to conduct the rotational force E from its upper part to the lower part.

3 Brief description of the patterns

S N The invention will now be explained in more detail in connection with some embodiments, referring to the accompanying drawings, of which: Figure 1 schematically shows a power line electric pole viewed from above;

Figure 2 schematically shows the foundation of the column viewed from the side and in cross-section; and Figure 3 schematically shows the lower part of a fork rod.

Detailed description of the invention Figure 1 shows an example of a column where the foundation shown here can be used. Figure 1 shows the power line electric pole 1. The electric pole 1 in Figure 1 has two legs 2. Under each leg 2 is a foundation 3. To support the electric pole 1 according to Figure 1, braces 9 are typically also used. therefore, only one harrow 9 is illustrated in Figure 1. The harrow 9 has a harrow bar 10. The harrow bar 10 has means for fitting the harrow bar 10 to the soil by twisting it. The harrow 10 can therefore be installed in the soil by twisting or drilling. In the embodiment of Figure 1, the means for fitting the fork rod 10 to the soil comprise a spiral blade 11 fitted to the lower end of the fork rod 10.

There is a link 12 at the upper end of the fork rod 10. A work machine such as an excavator can be used to form the support structure of the pole, and the Digger's tool can be used to grasp the link 12 and rotate the fork rod 10 to install it in the soil. The harus wire 13 is still attached to the link 12.

In the embodiment of Figure 3, there is a transverse pin 14 in connection with the threaded wing 11 fitted to the lower end of the fork rod 10. The threaded wing 11 is formed in the sleeve 15. The pin 14 is again fitted to the sleeve 15 in question.

The rod part of the haru rod 10 can be attached to the pin 14. The rod part can, for example, be welded to the pin 14. It is also possible to form a loop at the lower end of the rod part, which is fitted around the pin 14. In this case, the mutual angle between the rod N part and the sleeve 15 can vary.

N The harrow bar 10 can be twisted into the ground using the installation bar 16. The lower end of the mounting rod 16 can have a groove 17, which can be adjusted in such a way that the pin 14 fits inside the groove 17. When the mounting rod 16 is then rotated E 30 from its upper end with a machine tool, the mounting rod 16 rotates the fork rod 10 from the threaded vane 11 at its lower end ©.

S In Figure 3, the mounting rod 16 is fitted outside the sleeve 15. If desired, the mounting rod 16 can also be formed in such a way that it can be fitted over the pin 14 in such a way that the mounting rod is fitted to the inside of the sleeve 15. In this way, the mounting rod 16 can be securely supported in the sleeve 15.

Figure 2 shows foundation 3. When forming foundation 3, a trench is first dug in the ground, which can be, for example, square. Of course, the trench can also be round or polygonal or other shaped. In terms of size, the trench can be, for example, such that one side of a square trench can be, for example, 2-5 meters. The size and, on the other hand, the depth of the trench depends on the soil and the necessary frost protection. The depth of the trench can be, for example, 50-100 cm.

One or more anchor piles 4 are inserted into the soil approximately in the middle of the trench. The anchor piles 4 can be, for example, screw piles or impact piles. The anchor piles 4 are installed in such a way that their upper ends are placed inside the casting box 5 used in the foundation 3.

Casting box 5 has a base and walls. When viewed from above, the casting box 5 can be, for example, a square or other rectangle. The side length of the square-shaped casting box 5 can be, for example, 500-1500 mm. The height of the wall of the casting box 5 can be, for example, 300-1000 mm.

Casting box 5 is an insulating material. The base and walls of the casting box 5 can be, for example, extruded polystyrene, i.e. XPS thermal insulation. In this case, the thickness of the bottom and walls of the casting box 5 can be, for example, 50-150 mm.

The casting box 5 can be a prefabricated module. In this case, there is no need to separately measure, design and form the parts of the casting box on the construction site. The casting box 5 can be formed, for example, from pre-made insulation boards that are connected at the construction site. Insulating boards can have pre-formed joint grooves, which are used to align the bottom and walls in place. The insulation boards can be attached to each other to form a casting box 5, for example by applying urethane foam or silicone AN suitable for use in wet areas to the N joints, or some other suitable material that attaches the insulation boards to each other and preferably also seals the joints. In order to attach the insulation boards to each other to form the casting box 5, tape or a plastic band machine or N 30 some other suitable solution can also be used. E When the anchor piles 4 have been adjusted in place, holes of a suitable size are formed in the bottom of the casting box 5 at suitable points so that the upper ends of the anchor piles 4 are placed inside the casting box 5. N When the casting box 5 is in place, an S 35 horizontal insulation board 6 can be fitted around it. The insulation board 6 can also be, for example, extruded polystyrene, i.e. XPS thermal insulation.

The insulating plates 6 can be fitted, for example, to the extent that the casting box 5 and the insulating plate 6 essentially cover the formed trench. After this, soil can be placed on top of the insulation board and to support the casting box 5 on the outside of its walls. The soil is adjusted so much that the excavated trench can be covered, except for the casting box 5. The same soil that was dug to form the trench can be used to cover the trench.

The casting box 5 is filled with concrete 7. The casting box 5 can therefore also be called a casting mold. Concrete 7 is preferably fiber concrete. It can also be done by fitting reinforcement to the inside of the casting box 5 and using conventional concrete to fill the casting box 5.

When pouring concrete 7, the anchor piles 4 are first filled from the inside with concrete. In this case, the anchor piles 4 get corrosion protection on the inside and additional rigidity. Then the casting box 5 is filled with concrete. While the concrete is still wet, the column grip 8 is installed in the concrete 7 at the top of the casting box 5. After this, the lower part of the pole can be attached to the pole grip 8, for example with nuts and/or welding and/or some other suitable fastening method.

In the figures, the support structure is shown as a support structure to be adapted to the electric pole of the power line. The shown support structure is also suitable as a support structure for other poles, such as a support structure for a single-legged electric pole, lamp post, railway pole or other similar pole.

It is obvious to a professional in the field that as technology develops, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments N are therefore not limited to the examples described above, but may vary within the scope of the protection AN requirements.
