Description

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

A known installation for the manufacture of reinforced concrete products, comprising a portal, a bunker-feeder, vertical guides with an upright-lowering cross-bar, on which sealing working bodies are fixed in the form of deep vibrators, and a formwork with hingedly suspended boards, equipped with a simultaneous locking mechanism. working position 1.

The closest technical solution to the present invention is a device for molding tubular concrete products containing a vibrating core concentrically based on the core and a form connected by means of flexible connections with a stripping mechanism 2 mounted on a self-propelled portal.

The disadvantages of the known devices are the time consuming and inconvenience of stripping.

The aim of the invention is to reduce the time and ensure the convenience of stripping.

This goal is achieved by the fact that in a device for forming tubular concrete products containing a vibra core mounted on an ira base and a form connected by flexible connections with a stripping mechanism mounted on a self-propelled portal, the latter is equipped with an annular form with a window and placed in afterwards by a vertically movable horizontal cross-member fixed on a form which is made with roller guides which are in contact with the inner surface of the rings A clip is connected by rigid connections to the vibrating core.

FIG. 1 schematically shows the proposed device in the working position, general view; in fig. 2 - a general view of the device when the raspalzbke; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one.

A device for forming tubular products from concrete mixes contains a vibrating core 1 mounted concentrically on the base and a form 2 connected by means of flexible connections 3 with a stripping mechanism mounted on a self-propelled gantry 4

The form-removal mechanism is provided with an annular shape-enclosing holder 5 with windows 6

and placed in the latter a vertically movable horizontal cross-member 7 fixed on a form which is made with roller guides 8 in contact with the inner surface of an annular cage connected by means of rigid links 9 to a vibrating core 1 of form 2. To the upper part of the outer form 2 is attached The forming cone 10 dl fills the molding space with concrete. Outside the form 2 and inside the vibrating heart I, vibrators 11 are installed in a staggered order to compact the concrete mix f.

5 The device is equipped with a lifting mechanism 12 traverse.

The installation for making concrete rings works as follows.

0 A concrete mixture is loaded through the cone 1.0 into the molding space bounded by the inner core 1 and form 2. At the moment of loading, vibrators P. can be included to ensure uniform compaction and distribution of the mixture. Horizontal traverse 7 is in the position shown in FIG. I. Upon completion of the molding of the concrete ring, the lifting mechanism 12 by the flexible link 3 raises the horizontal yoke 7 initially to the position shown in FIG. 2, when it is moved to the extreme upper position in the windows 6 prior to contact with the holder 5, it tears the half-form with the form 2. In connection with the presence of the roller guides 8, the separation occurs over the entire surface of the product evenly without distortions, which increases surface quality of the product. Upon further movement of the crosspiece 7, the cage 5 and the rigid links 9 of the vibrating core 1 are displaced to it. Thus, the product is completely disassembled. When the mold 2 and the vibrating core I and the holder 5 are lifted above the formed product, the portal is moved to a new workplace where the vibrating core 1 with the holder 5 and the mold 2, which is centered during the lowering process with the help of roller guides 8, are lowered onto the base.

The use of the proposed device allows to reduce the time and improve the convenience of stripping.
