Method for producing cast-in-place flexible joined-together constructional structures and buildings

A method for producing monolithic-flexible joined-together constructional structures and buildings which comprises:

• cleaning the space between precleaned mating surfaces of the constructional structures and buildings involved;
• placing a plurality of rubber rods having diameters of about 4 to 6 mm and made of a vulcanized rubber or a polysulfide-containing compound which is longitudinally reinforced with a metal wire rope into the space between the mating surfaces;
• applying a 0.1 to 2 mm thick layer of a polysulfide-containing compound upon the precleaned mating surfaces to coat those surfaces, with the polysulfide-containing compound also being applied to the rubber rods, and wherein the polysulfide-containing compound incorporates the following components, wt. %:
• ______________________________________ liquid polysulfide 80-120 inorganic pigment 20-45 vulcanizer of aerobic rubber hardening 6.5-10 adhesive additive 5.5-7.5 rubber hardener 0.05-0.15 cross-linking agent 2.6-4.1 modifier 0.3-0.4 coal tar 14.5-31.2 ______________________________________
• filling the space between the polysulfide-containing compound coated mating surfaces with a mortar based on a cement that has a maximum expansion ratio of 0.3% under a pressure of 4 to 6 bar to assure that the entire space is filled, even when diverse configurations are present, and to force the mortar to penetrate into the polysulfide-containing compound layer to facilitate bonding thereto;
• and
• holding the resultant joined-together constructional structure or building for a period of time sufficient to vulcanize the polysulfide-containing compound and harden the cement based mortar, thus attaining elasto-monolithic properties for the joined-together constructional structures and building involved.

• filling the space between the polysulfide-containing compound coated mating surfaces with a mortar based on a sulfoferritic cement that includes a superplasticizer in a maximum amount of 0.7% of the dry cement weight, a cement setting promoter, and an aqueous polysulfide dispersion containing a dry-matter content of 40 to 60% to enhance adhesion to the polysulfide-containing compound layer, rubber rods or the mating surfaces, with the mortar having a maximum expansion ratio of 0.3% and being filled into the space under a pressure of 4 to 6 bar to assure that the entire space is filled, even when diverse configurations are present, and to force the mortar to penetrate into the polysulfide-containing compound layer to facilitate bonding thereto;
