Especially in Nordic conditions, piers have to be removed from the water from time to time due to the freezing of the water body. Piers are often located in awkward places, where it is difficult and sometimes even impossible to move or lift them, for example with the help of various lifting equipment. Particularly in view of such conditions, it is advantageous to form the berth from several parts, in which case the sizes of the berth elements should be chosen so that they can be moved and installed at least in individual parts. In the above-mentioned Finnish utility model, the body of the edge element 10 is preferably formed on the one hand from a frame formed by side parts into a circumference running substantially along the side edges and end edges, to which a planar upper surface such as a plate, grating or the like can be attached. Toi-15, the frame includes a support portion arranged to connect the center portions of substantially opposite side portions of the frame to each other. The above solution provides an ideal set of berth elements of suitable weight and rigidity to form a sufficiently rigid body to support a cylindrical float rotatably attached thereto.

In particular, following the current needs of the market, it has been found that there is still a need to simplify the docking element or the like in order to reduce its weight, as well as its manufacturing costs and selling price. In this context, it has been noted that with regard to the frame structure of the berth / • · · ·: it is still possible to simplify its structures, in which case, as the weight of the berth / berth element decreases, utility model application: dock / dock element according to the "float": 1 · 1 35 floats fixed to the frame. · »·» · 3 97 The 818 piers can be loaded with even relatively large eccentric loads. In practice, however, the body of the berth element in question is quite heavy, which does not cause a significant disadvantage when using a rotating float except mainly when lifting the berth element.

However, in particular, the size of the berth element with fixed floats should be kept quite small when using a frame construction of the type described above, so that the lifting of the berth element and the like.

10 manual handling is possible without separate auxiliary lifting devices.

The purpose of the frame structure according to the present invention is to provide a decisive improvement over the above-mentioned drawbacks and thus to substantially increase the state of the art in the art. To achieve this purpose, the frame structure according to the invention is mainly characterized in that said support part is fixed at each joint at least by a first welded joint to the web wall and a second welded joint to at least one of its stiffening walls joining the web wall.
