Description

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

The purpose of the invention is to reduce the labor intensity of stripping and to provide the opportunity for readjustment for the manufacture of products of various sizes.

FIG. 1 schematically shows a form for the manufacture of products from concrete mixtures, a plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a view of B in FIG. 2

The form for the manufacture of products from concrete mixtures, for example, with reinforcement outlets (columns of a bond version of unequal length), consists of a pallet 1 with internal separation liners 2, longitudinal flaps 3, end beads 4 with openings 5 attached thereto for forming niches around rebar releases. The end boards 4 are movable relative to the pallet and connected to the screw mechanisms 6 of the longitudinal stirring, by means of the stop bars 7 and axial parallel rods 8, the Probe formers 5 are hollow and equipped with spring-loaded springs 9, split stepped sleeves 10, the shanks of which enter coaxially mounted stop sleeves 11 with end slots (vertical and horizontal) for accommodating the latch 12. The slots in the sleeves 1 1 are made at an angle of 90 ° at different levels. The stepped sleeves 10 are provided with openings for rebar outlets that extend towards the inlet.

The conversion to the manufacture of shorter columns is carried out with the help of floating walls 13, kinematically connected by diagonally arranged adjustable telescopic arms 14 with end boards 4,

The form for the manufacture of products from concrete mixes works as follows. After preparation for concreting in accordance with the known technology (cleaning the mold, lubricating its internal surfaces, installing the reinforcement cage, etc.), the end walls 4 with the cores 5 attached to them are moved relative to the pallet 1 by means of a screw mechanism 6, thrust at the ends rebar

frame outlets, which are centered in the hole-forming unit 5 by spring-loaded split stepped sleeves 10, which are in the forming position, in which the front face planes of the sleeves 10 are flush with the face-faces of the shape-generating units, and the clamps 12 are in vertical slots x sleeves 11 (springs 9 compressed). The hole diameter of the stepped sleeves 10 corresponds to the specified size of the valve.

Then, the longitudinal flaps 3 are installed in the working position and the mold is filled with the mixture, after which it is subjected to vibration and steamed according to a known technology.

After steaming open the longitudinal

 The beads 3, and the retracting of the end beads 4 with the window formers 5 are carried out only after installing the split stepped sleeves 10 to the stripping position, in which the clamps 12 with the sleeves are turned 90 ° and moved to the horizontal slots of the sleeves 11. At the same time, the springs 9 unclenched , help the stripping process, dividing it into two stages: first, a sheet of end board 4 with opening-forming agents 5 departs, and then - split stepped

bushings 10 release reinforcement release. The springs 9 also facilitate the replacement of the split stepped sleeves 10 to another size with the latches 12 removed.
