Abstract

The invention relates to the manufacture of precast concrete and reinforced concrete products and improves the surface quality of the manufactured products. This is achieved by the fact that the mold for the manufacture of ribbed concrete mixtures plates is provided with clamps 6 and parallel beams 14 with poles 13. The poles 13 have slots 12 at the lower ends, and the tray 1 has brackets 9 with fastening devices and protrusions 11. a slot x 12 pillars 13 are provided with protrusions 11. The shaped shaping elements 16 and 17 are mounted on horizontal cross-arms 14. 2 Cp. f-ly, 6 ill.

Description

Fig

This invention relates to the manufacture of precast concrete and reinforced concrete products.

The closest solution of the known ones is the form for the manufacture of ribbed plates from concrete mixtures, containing a pallet mounted on supports, longitudinal and transversal boards and figured shaping elements (see dated German app. No. 1813094, class B 28 V 7/02, 1972)

formed at the lower ends supported on brackets 9 racks 13 traverse 14.

On the traverses 14 by means of stiffeners in the form of plates 15, 5 interlocked pairwise-shaped molding elements 16 and 17 are fixed, between which the concrete mix is laid to form the ribs in the manufactured products. The traversing bars 14 are attached to the building loops 18, and to the longitudinal bar the disadvantage of this form is 10 there 4 in the case of making short it’s impossible to achieve completely smooth plates - spacer elements 19, spacers due to the installation of slinging loops installation of manufactured products.

The aim of the invention is to increase

surface quality of manufactured products

placed between the latches 6 and the longitudinal sides, and to the bottom surface of the pallet 1 attached vibrators 20.

The form for making ribbed plates is as follows.

From the paver (not shown), the concrete mix is fed into the open windows 21 between the figured form-building elements 16 and 17 while the concrete paver (not shown) is being fed the concrete mix into the open-top windows 21 between the figured form-forming elements 16 and 17, when paired HViH with the racks having centering cuts on the lower ends, the pallet - - brackets with fixed

The pumped zol is achieved by the fact that the form for the manufacture of ribbed plates from

the concrete mixes are provided with latches and 20 vibrating vibrators 20. After filling the cavity of the form parallel with horizontal concrete mix, the surface of the concrete mix is smoothed in the windows between the forming elements 16 and 17. Then, after the fixtures and protrusions, the ridge plate is placed t

cut-in racks, and the curly sheathing of the casing, remove the curly shape-forming elements mounted framing elements 16 and 17

on horizontal crossbars. In addition, in the case of forming narrow ribbed

each retainer is made with horizontal plates of concrete mixes on a pallet 1 with vertical retaining screws, and a shorter transverse form is fitted with spacers, 30 beads) and Nearly less beams are shifted to the interleavers between the latches and the longitudinal axis of the pallet 1 and carry out

longitudinal sides.

fixing them with retainers, and then forming ribbed plates, as well as ribbed plates of normal width.

Claims (3)

1. A mold for the manufacture of ribbed slabs of concrete mixes, containing a pallet mounted on supports, the prodolysis of concrete mixes consists of a pallet 1, 40 full and transverse beams and figured ones installed by means of vibration-insulating and shaping elements, so that, in order to improve the surface quality of the manufactured products, it is provided with clamps and parallel to the rasborta, with the longitudinal 4 sides fixed with horizontal traverses laid on the pallet with clamps 6, with racks having centers centered along the longitudinal edges of the undercut lower ends, pallet - bracket 1, Vertical stop screws 7theins with fasteners the clips 6 while tightly pressing the tabs placed in the slots x the longitudinal sides 4 to the pallet 1, and the pillars, with the figured shaped horizontal stop screws 8 which prevent the elements from being mounted on the horizontal displacements of the longitudinal traverses, sides 4g relative to the longitudinal edges of the pallet 1. The transverse sides 5 are fixed on the transverse edges of the pallet 1, and in the case of forming the narrow plates on the longitudinal sides 4. The pallet 1 has 55 brackets 9 with fastening devices 10 and protrusions 11, which are placed in centering slots x 12, 2. The form according to claim 1, characterized in that each retainer is made with horizontal and vertical stop screws. 3. The form according to claim 1, characterized in that it is provided with spacer elements located between the retainers and the longitudinal sides. formed at the lower ends supported on brackets 9 racks 13 traverse 14. On the traverses 14 by means of stiffeners in the form of plates 15, blocked in pairs figure-shaped shaping elements 16 and 17 are fixed, between which the concrete mix is laid to form the ribs in the manufactured products. The traversing loops 18 are fastened on the traverses 14, and the spacer elements 19 are located to the longitudinal bars 4 in the case of the manufacture of short plates.  there 4 in the case of the manufacture of short plates - spacer elements 19, arranged placed between the latches 6 and the longitudinal sides, and to the bottom surface of the pallet 1 attached vibrators 20. The form for making ribbed plates is as follows. From the paver (not shown), the concrete mix is fed into the open windows 21 between the figured formforming elements 16 and 17 with the vibrators 20 operating.
