Method for producing prefabricated structural parts

Abstract

The invention relates to a method for producing prefabricated structural parts ( 5, 14 ) from a setting plastic compound for erecting buildings, in which the setting compound is filled into a shuttering and left to set into panels, two panels ( 12, 13 ) being joined together if necessary by means of reinforcements placed into the shutterings to form a double-walled panel ( 14 ). The built-in parts ( 3, 4, 20, 20′ ), which serve for the adjustable support of the prefabricated structural parts and/or for joining them to one another, are attached to the edge regions of the panels or double-walled panels, wherein the built-in parts ( 3, 11, 11′, 20, 20′ ) have fitting portions ( 8, 10, 21, 23 ), which serve as adjusting and joining points with respect to neighbouring panels or double-walled panels. In a further method step, the fitting portions are worked at positions that are fixed with respect to the panels or double-walled panels, in order to compensate for deviations in the position of the fitting portions from the intended dimensions of the panels or double-walled panels. The invention also relates to prefabricated structural parts produced by the method.

1 . A method of making prefabricated structural components from a hardenable plastic material for erecting buildings in which the hardenable material is poured into a formwork and allowed to harden into plates, the method comprising the steps of:
 installing mounting fittings that function to support the prefabricated structural components and/or to attach them to each other at edges of the plates, the mounting fittings having parts that function as alignment or attachment points for adjacent plates or double-walled plates, and   shaping the parts in a further procedural step at positions determined for the plates or double-walled plates so as to compensate for any deviations in the position of the parts relative to the intended dimensions of the plates or double-walled plates.   
     
     
         2 . The method according to  claim 1 , wherein the parts are made of plastic. 
     
     
         3 . The method according to  claim 1 , wherein the parts are provided with frustoconical alignment surfaces by milling, or are provided with generally conical alignment surfaces to allow the plates or double-walled plates to be aligned. 
     
     
         4 . The method according to  claim 1 , wherein molded blanks of the parts are molded onto the mounting fittings, such that the molded blanks fit to both sides of the edge of an opening of the mounting fittings. 
     
     
         5 . A prefabricated structural component in the form of a plate that is produced according to the method of  claim 1 , wherein the plate is a bottom plate, at least three of the mounting fittings being additionally provided with height-adjustable supporting elements to support the bottom plate against a base. 
     
     
         6 . The prefabricated structural component according to  claim 5 , wherein the parts of the mounting fittings of the bottom plate are parallel to a plane of the plate for attaching multiple bottom plates one below the other, and in a direction perpendicular to the plate plane for attaching the bottom plate to a double-walled plate in the form of a vertical wall, and that at least two parts are provided per alignment on at least one, preferably each narrow edge face of the bottom plate. 
     
     
         7 . The prefabricated structural component in the form of a double-walled plate that is produced according to the method of  claim 1 , wherein the double-walled plate is provided in the form of a vertical wall, wherein the parts of the mounting fittings are aligned in the direction of the plate plane for attaching a vertical wall to another vertical wall and/or bottom plate, and that at least two parts each are provided on at least one narrow edge face of the vertical wall.
