Definitions

• the invention relates to an improved method for erecting reinforced concrete building structures having pre-fabricated surface panels of hygroscopic, porous and capillaric material and further having a reinforcing steel rod meshwork.
• the surface panels and the reinforcing meshwork are in terfused by cast concrete so as to form a substantially monolithic bearing structure for the building to be erected.
• the covering outer surface elements of the final bearing structure - by using temporary support means - are arranged by vertically and horizontally joining of porous, capillaric surface panels duly pre-fabricated in modular sizes from plaster or from any other preferably gypsumbased material.
• the steel rod reinforcement netting of the bearing structure is assembled and put to place.
• the porous, capillaric surface panels and the reinforcement are interfused so as to form a substantially monolithic bearing structure, and finally, after setting of the filled-in concrete as final step of building erection the temporary support means is removed.
• An object of the present invention is to provide a novel improved method for erecting reinforced concrete building structures the method providing an easier temporary fixing and support of the vertically and/or horizontally arranged surface panels and other structure elements, and resulting in a rapid and more economic on-the-spot assembly of the structure elements without any temporary support means.
• an improved method for erecting reinforced concrete building structures comprising the steps of forming first a substantially self-supporting rigid spatial reinforcement meshwork for at least a part of the building structure to be erected by rigidly coupling raster-shaped, substantially planar and/or spatial steel rod nettings cut to size from pre-fabricated panelled rod mesh.
• pre-fabricated surface panels of hygroscopic, porous and capillaric material are secured to the rigid spacial reinforcement meshwork.
• the surface panels have a substantially even. smooth outer surface and a raster-shaped mesh grooved inner surface.
• the spacing distances of the raster of the mesh-grooves in the inner surface of the panels are substanially identical with that of the steel rod nettings of the rigid reinforcement meshwork.
• the mesh-grooves of the surface panels are capable of at least partially embedding the reinforcement meshwork which they are secured to whereby the reinforce ment meshwork serves simultaneously as supporting structure for the surface panels.
• the space of the reinforcement meshwork enclosed by or adjacent to the inner surfaces of the panels is filled in with cast concrete forming thereby the desired reinforced concrete building structure by simultaneously utilizing the surface panels as remaining formwork for said structure.
• the pre-fabricated surface panels of hygroscopic material Prior to securing the pre-fabricated surface panels of hygroscopic material to the rigid spatial reinforcement meshwork, preferably all or at least some of the structural members or at least fixtures, fittings or casings for such members and/ or building installations like pipes, power cables and the like may also be fixed to the rigid spatial" reinforcement meshwork while it is formed for at least a part of the building structure to be erected.
• the surface panels are pre-fabricated by form- pressing of a mixture of swollen pearlite with a suitable binder added.
• the improvement lies in that - against all known methods - first the reinforcement meshwork for the bearing strudure of the building is at least partially formed.
• raster-shaped steel rod nettings are used the raster spacing distances of which are integer parts of the modular length unit of the system.
• planar and/or spatial steel rod nettings are rigidly coupled by means of welding, of screwing or of wireing whereby a substanti ally self-supporting spatial reinforcement meshwork capable of load bearing to a certain desired degree is established. While forming said reinforcement meshwork, preferably installations like power supply cables, pipes and the like may also be secured to it.

• spatial steel rod nettings 2 for vertically extending structural parts and spatial steel rod nettings 3 for horizontally extending structural parts of the building structure to be erected are made by inserting suitable distance members between pairs of cut to size raster-shaped rod mesh panels 1 having a raster with spacing distances derived from the modular length size unit of the system and pre-fabricated industrially in large series preferably by welding of reinforceing steel rods of a diameter suitable to meet the static load requirement of the structure to be erected.
• Said mesh panels 1 and/or nettings 2 should be rigidly connected to each other preferably by welding, though any other suitable fixing mode, e.g. wireing, etc. may be applied for fixing.
• any other suitable fixing mode e.g. wireing, etc. may be applied for fixing.
• a rigid, self-supporting spatial reinforcement structure which is not only suitable for holding and supporting of surface panels 4 (to be dealt with later), covering preferably both the inner and the external wall surfaces of the structure but the rigid meshwork can be utilized simultaneously as grading means for the proper arrangement of said surface panels 4.
• Installations like power cables S of the building are preferably arranged within and secured to the rigid spatial reinforcement meshwork.
• construction work is continued by arranging and fixing the surface panels 4 next to each other to said meshwork whereby both an external outer wall cover and an inner wall cover are established.
• the pre ferably heat-insulated surface panels 4 are made of highly hygroscopic, porous material so as to ensure a proper concrete setting later, and they have a substantially even, smooth outer surface, while on their other, inner surface facing the reinforcement meshwork there are raster-shaped mesh-grooves 5 capable of embedding the reinforcement meshwork since the spacing distances of the mesh-grooves 5 are substantially identical with those of the rod mesh panels 1 and nettings 2 and 3 forming the reinforcement meshwork.
• Said spacing distances are equally derived from the modular length size unit of the system applied.
• steel pins 6 projecting towards the reinforcement meshwork when arranged on it are embedded.
• the panels 4 are rigidly fixed to the meshwork by connecting the steel pins 6 to the rods of the nettings 2 and 3 respectively by means of welding, wireing, by bending the pins 6 around said rods, or in any other suitable manner.
• thin-liquid concrete 9 is poured or pumped into the space formed by the mesh-grooves 5 of the surface panels 4 substantially embedding the reinforcement meshwork.
• the external building wall surfaces may freely be plastered and/or coloured in order to improve their quality and appearance, if required.
