HAMZA INDUSTRY ing., PRAGUE (54) Prefabricated Tank Building 1 The present invention relates to a prefabricated tank building panel in which the side walls incorporate metal strips projecting into the space of the grooves formed in the side walls. This treatment ensures the watertightness of the joints.

Prefabricated reinforced concrete tanks, mainly used in water management construction and storage and technological water treatment, have walls usually made of vertically mounted prefabricated parts, anchored to the reinforced concrete slab and to the upper iron-concrete rim. This construction system allows for a large dispersion variability of the tanks with the minimum kind of required prefabricated parts. The prefabricated elements for tank construction are produced in a way that guarantees the required properties, in particular the technical watertightness of the concrete. During construction, the walls of prefabricated parts are monolithed by concreting their joints. The concreting of the joints makes it possible to create the necessary space between the prefabricated elements or grooves in the side walls of the prefabricated elements. The joints of the prefabricated elements and the concrete joint filler are the structural joints of the structure. Due to the large overall length of the joints, cracks may occur in some places, for example due to the shrinkage of the concrete, which may cause insufficient water tightness of the tank. Retrofitting these defects is difficult and costly.

These disadvantages are overcome by the prefabricated tank construction element according to the invention, in whose side walls metal strips protrude into the space of the grooves formed in the side walls. 215 708

Claims (1)

The object of the invention is a prefabricated construction for the construction of tanks, in whose side walls metal strips protrude into the space of the grooves formed in the side walls. This treatment ensures the watertightness of the joints. Prefabricated reinforced concrete tanks, used mainly in water management construction for the accumulation and technological treatment of water, have walls usually constructed from vertically mounted prefabricated parts, anchored to the reinforced concrete foundation slab and to the upper reinforced concrete ring. This construction system allows for a large dispersion of the tanks with a minimum kind of required prefabricated parts. Prefabricated components for the construction of tanks are produced in a way that guarantees the required properties, in particular the technical watertightness of the concrete. During construction, the walls of prefabricated parts are monolithed by concreting their joints. The concreting of the joints is made possible by creating the necessary space between the prefabricated elements or grooves in the side walls of the prefabricated elements. The joints of the prefabricated elements and the concrete joint filler are the construction joints. With a large overall length of joints, cracks may occur in some places, for example due to concrete death, which may cause insufficient waterproofing of the tank. Retrofitting these defects is difficult and costly. These disadvantages are overcome by the prefabricated tank construction element according to the invention, in whose side walls metal strips protrude into the space of the grooves formed in the side walls. 215 708 The function of metal belts is twofold. In the case of concrete mortar in the joints, the metal strips are clamped with concrete, which ensures the waterproofness of the joints. In the event that, exceptionally, in some places, a crack occurs between the face of the groove, the metal strip and the concrete filler of the joint, the built-in metal strip substantially prolongs the leakage path and thus ensures the required degree of water tightness. The reliability of the joint sealing function can be increased by using expandable concrete to fill joints. In the accompanying drawing, an exemplary embodiment of a prefabricated container construction according to the invention is shown, in which Fig. 1 shows a vertical section through an axial plane; Fig. 2 shows a horizontal section. The prefabricated tank building element 1 has metal strips J incorporated in the side walls 2, which project into the space of the grooves 4 formed in the side walls 2. SUBJECT OF THE INVENTION Prefabricated component for the construction of tanks, characterized in that metal strips (3) which project into the space of grooves (4) formed in the side walls (2) are incorporated in its side walls (2). 1 drawing
