SU1470898A1 - Device for retaining protective concrete layer over reinforcement - Google Patents

Abstract

The invention relates to fixtures for fixing a gap between reinforcement and a wall of a form, providing the formation of a protective layer of concrete for reinforcement in the manufacture of reinforced concrete products. Allows you to simplify the fixation of valves and expand the technological capabilities of the lock. It is a concrete insert 1 in the form of a rhombic parallelepiped. To fix the reinforcement cage 2 in a closed detachable form 3, the liners 1 are laid on its base and then the frame 2 is installed, the transverse reinforcement of which rests on the rhombic faces of the inserts 1, which in turn, with their obtuse angles, rest on the base of the form. Similarly, they ensure fixation from the sides and on top of the form, which is covered with the removed half-form. When fixing to the side, the liners can be installed as a wedge with their rhombic edges converging at an acute angle. 2 Il.

Description

The invention relates to devices for fixing a gap between reinforcement and a wall of a form, which provides for the formation of a protective layer of concrete for reinforcement in the manufacture of reinforced concrete products.

The purpose of the invention is to simplify fixation of reinforcement and expansion of technological capabilities of the fixer.

FIG. 1 is a diagram of the installation of an insert for fixing the reinforcement in a closed plug form; in fig. 2 - the same, in the open top form.

The latch is a concrete-embedded insert 1 having the shape of a rhombic parallelepiped.

For fixing the reinforcement cage. 2 in a closed detachable form 3, for example, when preparing tubular reinforced concrete products, the insert 1 is placed in a row on the base of the half-mold, into which it is then installed. frame 2 so that its transverse reinforcement rests on the rhombic faces of the insert 1, which, with their obtuse angles, rest on the base of the half-form. Then, from two opposite sides, between the walls of the half-form and the transverse rods of the frame, the inserts 1 are inserted in a horizontal position, which, as well as below, rely with their rhombic edges on the reinforcement and an obtuse angle on the walls of the half-form. After that, on top of the frame, with such a bearing on the reinforcement, a row of liners is installed in their vertical position. Subsequent installation

the second half-form (not shown) of its wall rests on the blunt edges of the upper row of inserts 1.

For fixing the reinforcement cage 2 in the open 4-top form of its installation with the support on the bottom vkpadyshm

1 is produced in the same way as in the split form 3, and for fixing the frame

2, the side walls of the form 4 are inserted into the insert 1 with a sharp edge downwards, while the rhombic faces of the insert 1 converging at an acute angle, like a wedge, enter with the support on the longitudinal reinforcement of the frame 2

and side walls of form 4.

When fixing an armature, it is not necessary to attach it to it in Chapter 1, since the frame is prevented from moving the rhombic faces of the inserts, which also provide its self-centering, which simplifies the fixation of the reinforcement. The rhombic shape of the faces of the inserts allows it to be used for fixing the reinforcement cage from the bottom, sides and top, which expands its technological capabilities.
