Definitions

• the object of the invention is a base structure as defined in the preamble of claim 1.
• the solution according to the invention is well suited to be used e.g. as a base of traffic signs or as a base of some other corresponding device or product provided with a verti ⁇ cal post, e.g. as a base of the vertical stem of an outdoor lamp.
• the arrangement according to the invention can be used, for instance, as a base for fence posts.
• a problem in installing a traffic sign, a lamp or corresponding provided with a post-like stem into the ground is often that the installation must be performed sufficiently deep so that the installation would be durable, and in public facili ⁇ ties it should also withstand vandalism. Digging deep in the installation phase is slow and can damage e.g. underground cables or pipes.
• a solution inter alia, wherein a lattice-type platform is dug to a certain depth under the ground, has been developed to solve the problem. There is, however, no need to dig the lattice base to as deep down as the bottom end of a vertical post should be dug without the lattice base.
• a vertical post is fixed to the lattice base e.g. by welding.
• a problem in this solution is that the lattice base cannot necessarily be brought into the exact horizontal plane, in which case get ⁇ ting the vertical post into a vertical attitude is more dif- ficult. In addition, welding fixing at the installation site is awkward and slow to perform.
• the aim of the present invention is to eliminate the afore ⁇ mentioned drawbacks and to achieve as advantageous and simple a base structure as possible by the aid of which the vertical post of a traffic sign, of a lamp or corresponding can be installed into the ground easily, quickly and firmly.
• Another aim of the invention is to achieve an adjustable base structure, on which the vertical post can always easily be adjusted- into the vertical position irrespective of in what position the lattice platform is to be installed.
• the base structure according to the invention is characterized by what is disclosed in the characterization part of claim 1.
• Other embodiments of the invention are characterized by what is disclosed in the other claims.
• the base structure according to the invention is that it is advantageous, simple and operationally reliable in its structure and it is also easy to adjust so that the vertical post of a traffic sign, of a luminaire or corresponding can always be installed in a vertical position. Another advantage is the rapidity of the installation, because the vertical post or its extension piece does not need to be welded to the lattice platform. An advantage is also the secure fixing in its position. The vertical post locks firmly into its position and stays straight well.

• the second end, i.e. the bottom part, of the stem of the tightening means 4 presented by Fig. 6 is bent into a hook-shaped structure, in which the tip of the hook 4c points essentially backwards towards the first end of the tightening means 4.
• the stopper element 9 is not needed and the lock ⁇ ing means 3 can be fixed and tightened directly from above to on top of the spherical bottom part 7 of the fixing piece 2 by threading the tightening means 4 from above through the apertures lb of the lattice-type platform 1 to below the walls la and by performing the final anchoring and tightening by the aid of nuts 4c.
