HEATING FORMWORK FOR CONCRETING Russian patent published in 2022 - IPC E04G9/10 

FIELD: construction industry.

SUBSTANCE: invention relates to construction and can be used as a heating formwork for concreting monolithic structures. The frame of the heating formwork for concreting serves to connect its elements, namely the insulation, the inner and outer layer of the deckform. Between the deckform layers there are spacers distributing the concrete pressure, and there is a container with flexible walls containing a liquid substance capable of an exothermic reaction to form a solid substance with the possibility of performing the function of a sealing insert, while the container is made with the possibility of extracting it for a reverse endothermic reaction. The heating formwork for concreting works as follows. A container with a liquid substance capable of a controlled exothermic reaction is placed between the two layers of the deckform. Concrete is poured and an exothermic reaction is started in a flexible container. The resulting solid matter performs the function of a sealer between the layers of the deckform. Through the deckform layer, heat is transferred from the container to the concrete, while the insulation creates the effect of a “thermos”. If there was not enough heat, then the container is carefully removed from the formwork and it is heated, for example, in hot water, to conduct an endothermic reaction. When the substance becomes liquid in the container, it is placed back between the layers of the deckform.

EFFECT: expansion of the range of solutions for the construction industry.
