SU443764A1 - Form for the manufacture of reinforced concrete products of complex profile - Google Patents

Description

one

The invention relates to molds used in the manufacture of precast concrete and other industries associated with molding.

The known form for the manufacture of the product is 5 LIU of a complex profile that includes rigidly connected to the pallet by means of a conical bead lock.

In a known form, the cone and socket are mounted horizontally, i.e. in the direction of the movement of the sides being moved, and of the independent role as a device providing mechanized demolishing and automatic rigid fixation of the sides, they do not perform.15

The chain of the invention is to facilitate the process of stripping and assembling the mold.

It is achieved by the fact that the conical retainer is made in the form of a rod, vertically fixed on board, 20

which exceeds the height of the conical hole in the bottom by an amount limited by the stop mounted on the end of the cone.

FIG. 1 depicts the proposed 25

shape, side view; in fig. 2 is the same as FIG. 3 is a section along A-A in FIG. one; in fig. 4 - the same at the moment of stripping; in fig. 5 - section along BB for fng. one;

The proposed form consists of a pallet 1 and eight beads 2. Each bead 2 is provided with two cones 3 and is inserted into conical sockets 4 fixed on the pallet. The cone 3 is threaded and has a lock washer 5, fastened with a nut 6, which limits the upward movement of the bead. The length of the cone 3 exceeds the depth of the socket 4.

The two fold-in liners 7 are connected to the sub-base 1 by the hinges 8 and serve to form a gap between the adjacent beads 2. The pallet 1 and the beads 2 are hollow and form a steam jacket.

In the manufacture of products in the proposed form, the operations of cleaning and lubricating the working cavity of the mold, installing the reinforcement cage and inserts, laying and compacting the concrete base, smoothing, steaming the product in (and demoulding) are performed; crane stripping is performed by: after having folded the liners 7. When lifting, together with its flanks 2, there appears a gap between the cone 3 and the jack 4, and this node starts to work as a hinge, ensuring the radial detachment of the flange 2 from the post but by moving the washer 5 to the end of the cone 3, cut off from the bead 2 and return the latter under its own weight to the working position with exact and I rigid fixation in the sockets and on the tray 1. After cleaning and lubrication, the shape comes to working readiness. The invention of the Form for the manufacture of reinforced concrete products of a complex profile, including a rod rigidly connected to the pallet using a conical bead lock, is different from the fact that, in order to facilitate the process of stripping and assembly of the form, the conical the lock is made in the form of a rod vertically fixed on board with a length exceeding the height of the taper hole in the pallet by the amount limited by the stop mounted on the end of the taper.
