Description

one

The invention relates to the manufacture of predominantly thin-walled, reinforced concrete structures in multi-bed forms.

A well-known multi-site form for the manufacture of reinforced concrete slabs, containing a pallet, sides and partitions rigidly attached to the pallet, between which elastic liners 1 are placed.

The closest to the technical essence and the achieved result to the proposed is the installation containing a vibrating plate, on which a multi-seat form is placed with longitudinal and transverse sides, dividing partitions and a pallet with slots for accommodating the dividing partitions 2.

The disadvantages of the known installations are their increased meta-slaking capacity and the complexity of the process of folding of articles.

The purpose of the invention is to reduce the metal content of the equipment and the labor intensity of the spreader during the manufacture of prestressed products.

The delivered tolol is achieved by the fact that the extrusion for the molding of reinforced concrete and tlolium containing;

The vibroplatform on which the multi-seat form with longitudinal and transverse sides is placed, dividing partitions and a pallet with slots to accommodate the partition walls, is equipped with a drive of vertical vibrations of the vibrating plate, and the skid tracks with rollers and lugs for mounting the rebar, and the transverse boards are removable. Figure 1 shows the installation in the plan; figure 2 - section aa in figure 1.

The installation for molding reinforced concrete products contains a vibroplatform 1, on which is placed a lot of local form with a pallet 2, longitudinal boards 3, removable transverse 20 boards 4 and separation bars, towns 5 with guide grooves 6. Separation walls 5 are fixed on the vibrating plate 1 and enter in slot 7, formed in the pallet

25 2. The installation is equipped with an actuator 8 for vertical movements of the vibrating plate 1. The base 2 is supplied with power stops 9 for fastening the tension reinforcement 10 and the rollers 11. Hole 7 of the pallet during the molding period

sealed with rubber pads 12.

The installation works as follows.

The form with pre-tensioned reinforcement 10, tensioned on its stops 9, is installed on the vibrating plate 1 and equipped with transverse boards 4, In the slot 7 of the pallet 2 by means of 8 plant dividing partitions 5 and the longitudinal sides 3, fastened to the vibrating plate. The assembled multi-seat form is filled with a concrete mix and includes a vibrating platform. In order to avoid leakage of cement milk, the slits of the pallet are compacted with rubber pads 12. At the end of the compaction, the side boards 4 are removed and, together with the vibrating bar 1, lower the partition walls 5 and the longitudinal sides 3 completely free the product 13 from the formwork. The products remain fixed on the pallet 2 by prestressed reinforcement 10 and, together with the pallet mounted on the rollers 11, are sent to the heat treatment station.

The use of this plant for the manufacture of pre-stressed products reduces the metal intensity of the mold fleet by 25–30%, and the labor intensity of the stripping work by 70–80%. In addition, the installation

The proposed design allows it to produce thin-walled pre-stressed products in a vertical position, which will increase by 10-15 times the removal of products per unit area.
