SU1219764A1 - Device for forming voids in ferroconcrete articles - Google Patents

Description

The invention relates to the production of reinforced concrete products in cluster installations and can be used for demolding and installation of precast concrete and reinforced concrete products.

The purpose of the invention is to expand the field of use of the device by allowing it to be used when removing from a mold, transporting and installing products.

FIG. 1 shows the product with the proposed device; in fig. 2 — node 1 in FIG. (liner not shown); in fig. 3 shows section A-A in FIG. 2; in fig. 4 - cone-shaped element, axonometric.

The device for the formation of voids in a concrete product I consists of a finger 2 fixed on the wall 3 of the cassette compartment of the cone-shaped element 4 with a socket for fitting it on the finger 2 and a groove 5 made along the longitudinal axis of the element, on the side surface of which is parallel to the axis a key protrusion 6 of a segmental shape, as well as a pin 7, made with a segmental notch at one end and with a slinging loop at the other. The groove 5 is closed by an insert 8, for example, made of rubber, and the pin 7 in the area from the upper plane of the product to the conical element is secured by a tube 9 made of a polymeric material.

The assembly of the cassette with the dominant device installed therein is carried out as follows.

In the open compartment of the cassette install reinforcement block, to the wall 3 of the compartment which is fixed fingers 2, and put on the fingers cone-shaped elements 4. Then through the groove. 5, the pin 7 is inserted so that the segmental protrusion 6 in the groove 5 enters the corresponding recess in the pin 7. Pre-install the tube 9 on the pin 6. After this, the groove 5 of the cone-shaped element is tightly closed with the liner 8, and then the compartment is shifted and the device is installed in the following cassette compartments. In this case, depending on the type of reinforcement block (flat or spatial frame), the device can be installed both on the movable and fixed walls 3 of the compartment.

After laying the concrete mix in the compartments and heat treating the products, the cassette is dismantled. In addition, the wall 3 of the compartment is retracted, into the slinging pin 7

the load gripping element is passed through and the product I is lifted and transported first to the technological stations, then to the finished goods warehouse, and then to the construction site.

After installation of the products on the construction site, the device is removed from them. To do this, remove the liner 8, knock out the cone-shaped element 4 and remove the pin 7 from the tube 9. The device in the kit is returned to the product manufacturer for its reuse.
