Supporting device for the construction industry, arrangement consisting of at least two such supporting devices, incremental launching device comprising at least one such supporting device, and method for supporting a load element using such a supporting device

A supporting device for the construction industry, comprising:

• a fixing element, designed to rest against a side wall and to be fixed to a fixing point of the side wall;
• a cantilever, which is connected to the fixing element and protrudes from the side wall when the fixing element is in the fixed state such that a load element can bear against a bearing point of a bearing element of the cantilever, wherein the load element can be moved with respect to the cantilever in a movement direction that is substantially parallel to the side wall, and which cantilever is coupled to the load element when the load element bears against the bearing element of the cantilever such that a movement force component acts on the cantilever in the movement direction due to a movement of the load element, which leads to a torque on the cantilever by means of a lever arm that reaches from the fixing point to the bearing point;
• and
• at least one rotation-reducing element, which is connected at one end to the cantilever and is designed to rest against the side wall by means of a different end when the load element bearing against the cantilever moves in order to counteract the torque on the cantilever.
