SU110392A1 - Method of forming waterproof concrete without heating panels - Google Patents

Description

It is known to manufacture heating metalless radiators from asbestos, eternit, etc., of materials by stamping them out of two halves, followed by joining or laying a paraffin model into concrete with subsequent smelting.

According to the invention, an industrial method is provided for producing heating-free heating panels with multiple use of a set of embedded elements. The panels are molded from waterproof concrete using rigid embedded metal rods, the complete set of which is laid in the form of gears before the panels are molded and removed after the rebar has been installed and the vibrating plate has been vibrated.

The schematic drawing shows embedded elements and their placement in the form.

In order to form two longitudinal channels of larger diameter, two rods / and 2 are installed with holes according to the number of transverse channels, fastened in two opposite end walls of form 3.

A network of transverse channels of smaller diameter is formed by a metal comb consisting of a row of thin metal rods 4 mounted on a single rigid cross bar 5. The combs' rods are inserted into the mold before forming through a series of holes in one of the longitudinal sides of the mold.

The installation of the comb rods into the desired position is ensured by passing them through the holes of one of the extension rods and inserting the second longitudinal rods into the holes without releasing the ends to the outside.

To connect the panel to the heating network to the flange of the mold, metal nuts 7 are fastened with nuts 6, which are subsequently JJb 110392

VII remain in the body of the panel. The nuts are at the same time temporary rod retainers.

After laying the reinforcing mesh and installing the embedded elements in this way, the form is fixed on the vibrating plate; Concrete is being laid and vibrated.

At the end of the vibration, the embedded elements are successively removed from the body of the molded panel: first the combs, then the longitudinal rod / located at the end of the rods of the comb; The second longitudinal rod 2 is initially only shifted along its axis by half the distance between the holes formed by the comb rods, thereby blocking the ends of the holes in the panel body formed by the comb.

After that, the unnecessary ends of all sections of the channels 8 between the bead and the rod 2. are sealed with a rigid waterproof solution through the holes 9 in the bead of the truss, while to ensure reliable sealing of the holes on top of the concrete, a hard cover 10 is installed (shown in dotted lines).

At the end of the embedding of the ends of the holes, the second longitudinal rod 2 is removed from the panel and the mold with the molded panel enters the heat treatment.

After the panel has hardened, the coupling retainer nuts are unscrewed and the panel dismantled.

Claims (2)

1. A method of forming from waterproof concrete concrete to heating-free panels, characterized in that the formation of a network of internal longitudinal and transverse channels is made by simultaneously laying a complete set of metal rods and then removing them after finishing the molding of concrete on a vibrating plate. 2. Reception; performing pop method. 1, characterized in that the sealing of the ends of the holes is provided by preliminarily shifting one of the rods by half the distance between the rods of the comb, after which the ends of the holes are sealed in the freshly compacted concrete of the panel.
