Description

The invention relates to the production of building structures, such as forms for the manufacture of concrete products.

A known form for the manufacture of construction 5 solid products, including a support frame with sides and a removable pallet with rollers. The pallet is mounted by means of supporting elements on the supporting frame and secured by elastic gaskets attached to the sides, each of which is hingedly mounted on the supporting frame [1].

The disadvantages of the known form are the presence of pivotal sides and locks fixing them, which affects the accuracy of manufacturing the products.

Also known is a form for the manufacture of building products, containing beads in the form of a closed contour with a pallet placed in it and interchangeable shaping elements with locking devices [2].

The disadvantage of this solution is the complexity of the design, which affects the accuracy of the manufactured products. In addition, this decision limits the range of production of products of a wide range.

The purpose of this invention is to ensure the release of a wide range of products with

high accuracy of their geometric dimensions.

This goal is achieved by the fact that in the form for the manufacture of construction products containing power boards in the form of a closed contour and interchangeable shaping contour elements mounted on a pallet, the beads are provided with base shelves rigidly attached to them, on which a beam is installed to support the pallet with two molding surfaces, and interchangeable shaping contour elements are equipped with devices made symmetrically about their longitudinal axis.

FIG. 1 shows a plan form; in fig. 2 - section A — A in FIG. one; in fig. 3 shows the form with the product when dismantling; in fig. 4 - section B — B in FIG. one; in fig. 5 - section B — B in FIG. 1 with liner and spacer for the manufacture of products of smaller size.

The form consists of power flanges 1, made in the form of a rigid contour frame, on which base shelves 2 are mounted on the inner side to install beam 3 along the perimeter of power flanges 1. Pallet 4 is made with two molding surfaces 5, 6, consists of one or several

parts 7 and installed on the console 8 of the beam 3, having in the upper part of the protrusion 9 for installing and fixing the removable forming contour elements 10.

The contour elements 10 on the side of the power boards 1 are provided with devices 11, for example in the form of a “dovetail”, made ’symmetrically with respect to their longitudinal axis for mounting and fixing on the pallet 4 relative to the power boards 1.

The fastening of the beam 3 to the power sides 1 is carried out using a connection, for example bolted, 12.

For the manufacture of products of smaller dimensions between the base shelf 2 and the bar 3, spacers 13 are installed, and between the power boards 1 and interchangeable shaping contour elements 10 are inserts 14 having devices for fixing them and installing them on a pallet 4 relative to the power flanges 1, similar to the devices 11 .

To move the form on the rails of the power side 1 is equipped with rollers 15.

Work is carried out in the following order.

Before forming the product, the mold is assembled.

On the console 8 put the pallet 4, on which they install interchangeable shaping contour elements 10, and the lower part of their "dovetail" 11 engages with the protrusion 9 of the beam 3, which ensures their fixation on the size of the product.

In the form stack textured layer and reinforcing cages.

Before laying the concrete mix, the replaceable shaping contour elements 10 and the pallet 4 are mutually fixed in the power boards 1 by a pressing device 16 relating to the molding station.

After that, the concrete mixture is put into the mold and compacted, the upper surface is rubbed and the clamping device 16 is withdrawn.

Then the product in the form enters the heat treatment, at the end of which the form is removed. During demolding, the pallet 4 with the product and the replaceable formative contour elements 10 is pushed up from the power ribs 11 (shown in FIG. 3). Replaceable forming contour elements 10 are separated, and the product at the formwork post is removed from the pallet.

Released power side 1, interchangeable shaping contour elements 10 and the pallet 4 are fed to the post complete set of forms for repeated cycles.

In the manufacture of products of smaller dimensions, the form is repositioned, for which between the base shelf 2 and the bar 3 distance spacers 13 and the corresponding forming contour elements 10 are installed (for products of smaller thickness), and between the power boards 1 and replaceable forming elements 10 - inserts 14 (for products shorter length or width).

The presence of symmetrical devices (for example, “dovetail”) for the installation and fixation of interchangeable shaping contour elements 10 allows in the process of using these elements to obtain products as from the top; and with the lower front surface.

The design of the insert pallet 4, made with two molding planes 5 and 6 from one or several component parts 7, allows to manufacture products with the most diverse architectural solutions of the front surface in the minimum number of forms.

Claims (1)

Claim A form for the manufacture of building products, including boards in the form of a closed contour with a pallet placed in it and interchangeable shaping elements with fixing devices, characterized in that, in order to ensure the production of products of a wide range, the boards are provided with rigidly attached shelves and a support bar mounted on them and fixing the pallet, the pallet being made with two molding surfaces, and the fixing devices are installed symmetrically with respect to the longitudinal axis of the forming elements Comrade.
