Description

[0001] The invention relates to a mobile foundation. The mobile foundation according to the invention is used in particular as a foundation for at least one structural element, preferably for at least one building support, particularly preferably for at least one hall support of a lightweight hall or tent hall. The lightweight halls or tent halls for whose supports the foundation according to the invention is used according to a preferred embodiment are in particular permanently erected lightweight halls or tent halls. The mobile foundation according to the invention is expediently a component of the floor structures of buildings and in particular of the floor structures of permanently erected lightweight halls or tent halls.

[0002] Such mobile foundations are known, for example, from WO2019 113 651 A1.

[0003] It is known in practice to produce monolithic concrete foundation blocks on site for building supports, and in particular for supports or hall supports of permanently erected lightweight halls or tent halls. Such foundation blocks, which are usually required for every support of the building structure, counteract the uplift forces. However, the monolithic foundation blocks known from practice and manufactured on site are characterized by a number of disadvantages. For example, the conventional foundation blocks must harden on site over a certain period of time after their production. This is complex and particularly time-consuming. Furthermore, the foundation blocks offer little variation in terms of their design and are not flexible in their use. - In this respect, there is room for improvement.

[0004] The invention is based on the technical problem of providing a foundation with which the disadvantages of the known foundation blocks can be avoided and which is, in particular, easy to manufacture and quickly ready for use at the place of use, which is variable in terms of its adaptability and which, moreover, can be used flexibly.

[0005] To solve this technical problem, the invention teaches a mobile foundation having the features of claim 1.

[0006] Here and below, unless otherwise stated, reference is made to the assembled state of the foundation, in which the at least one cover plate is the top-closing plate and the at least one base plate is the bottom-closing plate of the foundation and in which the plates are connected by the at least one connecting element, in particular by the at least one threaded rod.

[0007] An embodiment of particular importance within the scope of the invention is characterized in that the foundation according to the invention is a concrete foundation whose individual slabs are formed on a concrete basis and, in particular, consist of or essentially consist of concrete. The fact that the slabs of the foundation according to the invention consist essentially of concrete means, in particular, that these slabs can have conventional additives such as reinforcement and the like.

[0008] The invention is based on the finding that the construction of the foundation from at least two slabs connected by at least one connecting element enables flexible use of the foundation and rapid and reliable assembly of the foundation at the site of use. Within the scope of the invention, the slabs of the foundation according to the invention are not manufactured on site, but are used as finished and cured slabs, so that an on-site curing process is not necessary. The slabs of the foundation according to the invention are therefore expediently prefabricated slabs and in particular prefabricated concrete slabs. The prefabricated concrete slabs are connected to one another and preferably bolted.The term mobile foundation means that the foundation according to the invention is transportable due to its modular construction made of prefabricated panels and only needs to be assembled for use.

Thus, the upper end of the at least one connecting element(s), in particular of the at least one threaded rod(s), expediently does not protrude beyond the cover plate upper side. Within the scope of the invention, the length of the connecting elements is selected depending on the number of plates and, in particular, the number of intermediate plates of the foundation.

[0017] It is preferred that the at least one connecting element, in particular the at least one threaded rod, has a head at the upper end assigned to the cover plate, the diameter of which head is larger than the diameter of the connecting element or of the threaded rod. The connecting element, in particular the threaded rod, is therefore preferably designed as a screw. The head of the at least one connecting element expediently has a larger diameter than the remaining part of the connecting element. It is recommended that the head is designed on its upper side for interaction with a screwing tool and, for this purpose, expediently has a screwing tool receptacle.

For example, according to a preferred embodiment, the cover slab is thicker than the base slab and / or the at least one intermediate slab. In addition, the cover slab can preferably be provided with edge protection.
