Abstract

This invention relates to the manufacture of products from precast concrete and reinforced concrete. In order to intensify the process of compacting the concrete mix and reduce energy intensity, the elastic shock absorbers 5 and 6, as well as the causative agent of vibrations B, are displaced in the horizontal plane from the axis of the punch 4 at distances of 0.5-0.8, 1.5-1.8 and 0, respectively 8-1.6 distances between the side walls of the insert 13. 1 sludge.

Description

one

An invention in the manufacture of precast concrete and reinforced concrete.

The aim of the invention is to intensify the compaction process and reduce energy consumption.

The drawing schematically shows a device for molding concrete products, a general view.

The device consists of a frame in the form of a base plate 1, on which columns 2 are rigidly fixed with matrix 3 and punch 4 mounted on them. On column pillars 2, elastic dampers 5, 6 are suspended by means of elastic shock absorbers 8 oscillations 5 connected with electric drive 9 rigidly mounted on the rack 10. On the base plate 1 there is a mechanism of 11 vertical displacements associated with the bottom of the matrix 3 and made in the form of a power cylinder with a piston, above the rod of which there is an axle bearing. rigidly fixed in the lower part of the pusher, connected by its upper part with the bottom of the matjJ bF 3, the bottom of the matrix is made up of a molding glitch e and a pressing washer. The matrix 3 consists of a removable liner 13 fixed on the columns 12 with an internal outline corresponding to the outer contour of the moldable iztspi, the Punch 4 is connected to. the power cylinder 14, suspended from the traverse 15. In this case, the elastic shock absorbers to the exciter are oscillated relative to the vertical axis of the poise-gona 4 so that their vertical axes are located from the vertical axis of the punch

over distances, respectively 0.5-0.8, 1.5-1.8 and 0.8-1.6 distances between the inner side walls of the liner. Such an arrangement of elastic shock absorbers and a vibration exciter is determined experimentally and is optimal for intensifying the compaction process and reducing energy consumption.

The operation of the device is as follows.

When the base 3 is mounted on the movable frame 7, the concrete mix is poured into the matrix 3, after which the punch 4 is lowered by the power cylinder 14 and the process of vibropressing is completed, at the end of which the compacted product is pushed out
