Method and connecting element for connecting piles to basic parts

The invention relates to a method for connecting piles or the like to foot or similar base parts by means of a concrete connecting element, the casting work using a prefabricated, pre-reinforced tubular connecting element dimensioned to loosen the cross-sections of the commonly used piles and column sleeves, and time with building components in contact with it. The invention also relates to a connecting element used in the method.

When laying the foundations of buildings, it is often necessary to arrange a so-called the main pillar, especially if aiming below the frost limit or there are large elevation differences in the terrain. Such work involves many stages of work, such as mold making, reinforcement, casting, and mold disassembly. In addition to the making pillar 20 requires a lot of work, it also takes a lot of time.

The base pillar is sometimes also made of round "well rings" which are supported to a specified height, cut to a suitable length, reinforced and cast.

When laying the foundations, piling in a soft ground 25 will have to be carried out. If the pile has sunk deep, it must be continued. The extension is usually done by using a sheet metal barrel or a spiral tube as a mold, reinforcing it and casting it. Here too, as in the work presented above, on-site work is expensive and time consuming. Even for this work, intermediate pieces can be made in the warehouse, with which the continuation work can be carried out easily and quickly, so that the construction work can soon be resumed to the next stage.

SU 987 034 discloses a method of constructing the foundations of buildings, in which 2 84286 e.g. a column is connected to the foot part by using a concrete casting structure as a connecting part of the above-mentioned building parts. According to SUi-5, it is known from SU 408 077 to fasten a column sleeve element to the foot part so that the sleeve element remains partially in the casting of the base plate. It is also known from DE 2 341 651 to use reinforced tubular elements made of concrete in advance at casting ends of piles, which are dimensioned to be looser than the cross-sections of the piles.

The transfer and placement of known connecting elements in the workplace is cumbersome due to the high weight of the elements and usually requires large lifting devices.

It is an object of the present invention to provide a method which facilitates the transfer of elements. The method according to the invention is characterized in that at least one rod is inserted through the holes in the walls of the connecting element, by means of which the element can be mounted at the correct height 20 and position.

Pushing the rod through the holes in the connecting element provides a means by which the element can be moved and placed in place simply and quickly without large lifting devices.

The invention also relates to a concrete connecting element for connecting piles or the like to a base or similar base parts for use in the above method, the connecting element being a tubular, prefabricated reinforced concrete element located between the pile and the base part, which is intended to be cast in place at the same time. with building components in contact with. The connecting element is characterized in that the walls of the element have holes for at least one rod, by means of which the element can be mounted at the correct height and position.

The invention will be explained in more detail with the aid of the accompanying drawings. They schematically show application examples of some of the connecting elements according to the invention, which are used in the method according to the invention.

Fig. 1 shows an axonometric view of a pile j housing, Fig. 2 shows an axonometric view of a sleeve raising element, Fig. 3 shows an axonometric view of a hat element of a pile 10, Fig. 4 shows a sectional view of the use of an extension sleeve, Fig. 5 shows an axonometric view of the use of a sleeve Fig. 7 also shows the use of the pile cap in an axonometric view, Fig. 8 shows the use of the extension housing and the pile cap in an axonometric view.

Figure 1 shows an extension housing 8. It shows 20 holes 5 through which an iron rod can be inserted to facilitate handling and correct placement. The element is pre-reinforced.

Figures 4 and 8 show the extension housing 8 of the pile 7 in different use cases. In Figure 4, it has been used to extend 25 piles 7 under a beam 10 or the like. Figure 8 shows the extension of the pile 7 by means of an extension housing 8 under the pile cap 9. Casting work can be done at the same time so that the parts are cast together.

Figure 2 shows the sleeve raising element 3. It has 30 down-mounted irons 4 which bind the element to the base bone. Figure 5 shows how the raising element 3 of the sleeve 1 is cast on the sole 2. The extension element 3 also has holes 5 to facilitate installation.

Figure 3 shows a pile cap element 9. It 35 is similar to the extension housing 8, but of different dimensions. It is relatively low compared to the cross-sectional area, since its purpose is only to support the pile 7 and the structure 11, 12 intended to support the pile. This is illustrated in Figures 6, 7 and 8. In Figure 6, the pile cap 5 binds the floor 12 over the pile. In Figures 7 and 8 it supports the plinth structure 11 tied to the piles 7.

In the method according to the invention, elements are used for the structure between the foot and the column sleeve known per se, which are pre-reinforced and which can be mounted several times on top of each other. The same method is used between the pile and the foot if the pile is too deep. The pre-made pile-end hat element also connects the floor and the pile to promote and facilitate the work. In all these cases according to the invention, the use of pre-reinforced, prefabricated elements, which are cast together with other on-site casting work, provides an economically advantageous solution while speeding up the work.

The elements can be, for example, circular or square in cross-section, and otherwise the invention can be varied within the scope of the claims.
