Description

The invention relates to the construction industry, in particular to equipment for finishing freshly molded concrete products.

The purpose of the invention is to improve the quality of the finished surface of the product and simplify the design.

The drawing shows a device for smoothing the surface of products, side view.

The device consists of a frame 1, on which an elastic spatula 2 is installed, and a pneumatic cylinder 3 fixed on the frame and connected by duct 4 and a pressure regulator 5 to a source of compressed air (not shown).

ten

and a pressure regulator 5 with a compressed air source.

The surface finish is carried out in one pass of the spatula along the product, and depending on the plasticity of the concrete, the required pressure on the concrete and plough is obtained from the contact of the spatula with the product, which is achieved with the help of pressure regulator 5.

Invention Formula A device for smoothing the surface of freshly molded articles from be- The device works as follows. 5 tons of mixtures containing the mounted Form with product 6, moving along the frame with an elastic spatula from an adapted production line, are put into the post smoothing down the surface of the product, where either the form moves under frame 1 or to press it against the surface to be trimmed, characterized in that, in order to improve the quality of the surface being trimmed, the self-propelled frame 1 slides over the product and simplifies the design, which is placed spatula 2 for smoothing. The passage through the product, the spatula 2 is bent, pressing against the surface of the product, and exerts on it a certain pressure, which is reinforced by a pneumatic-ballon 3 connected through the air duct 4 The device for pressing the spatula to the surface to be trimmed is made in the form of an elastic pneumocylinder connected via a pressure regulator with a source of compressed air and in contact with the non-working surface of the spatula and the frame. and a pressure regulator 5 with a source of compressed air. The surface finish is carried out in a single pass of the spatula along the product, and depending on the plasticity of the concrete, the required pressure on the concrete and plough is chosen when the spatula comes into contact with the product, which is achieved with the help of pressure regulator 5. Invention Formula A device for smoothing the surface of freshly molded products from concrete mixes, containing an elastic spatula mounted on the frame to press it against the surface to be trimmed, characterized in that, in order to improve the quality of the surface being trimmed and to simplify the design, The device for pressing the spatula to the surface to be trimmed is made in the form of an elastic pneumocylinder connected via a pressure regulator with a source of compressed air and in contact with the non-working surface of the spatula and the frame.
