FORMWORK FOR FORMING REINFORCED CONCRETE PRODUCT AND METHOD OF ITS MANUFACTURING Russian patent published in 2025 - IPC B28B7/22 B28B7/24 E04G11/06 B28B1/08 

Abstract RU 2841243 C1

FIELD: construction.

SUBSTANCE: group of inventions relates to construction, namely to formwork for moulding reinforced concrete products, in particular seamless reinforced concrete blocks (modules) of U-shape, and to method of their manufacturing inside production facilities. Method includes preparation of formwork for pouring of concrete mixture, concreting, stripping and extraction of reinforced concrete article (29). When preparing the formwork, the transformable folding core is installed by means of hydraulic drives into the design position. Linear floors (11), end floor (10) are installed in design position. Reinforced frame (31) is installed in formwork compartments. Embeds are fixed. First, external shields (5), left end shield (6), right end shield (7) are sequentially installed in design position by means of manual drive (13), upper rods (14), lower rods (15) and lateral rods (16) are installed. Concreting process involves sequential filling of formwork compartments and vibration using vibrators (17). After gaining the required strength with concrete, stripping is performed, which is started with dismantling of upper (14), lower (15) and side (16) rods. Then, left end shield (6), right end shield (7) and external shields (5) are moved by means of manual drive (13) to maximum distance from reinforced concrete article (29). Further, geometrical folding of transformable folding core is performed with reduction of its longitudinal and cross section by means of hydraulic drives. Further, reinforced concrete article (29) is rafted by means of traverse (34) and removed from the formwork.

EFFECT: increased rate of reinforced concrete product forming.
