RU107096U1 - CONNECTIVE FORM FOR MAKING CONCRETE BLOCKS - Google Patents

Abstract

The utility model relates to technological equipment for the manufacture of concrete blocks with a decorative surface. The aim of the development is to expand the functionality of the demountable form, by changing the geometric dimensions. Another goal is to decorate products by means of relief formation on the side surfaces of blocks. This goal is achieved in that one of the walls of the mold containing the pallet and the wall with the fastening elements is removable. This wall contains special invoicing surfaces in the form of a set of replaceable polyurethane elements. The mold may also contain several removable walls with the ability to change the distance between them. Thus, it is possible to produce simultaneously several blocks with decorative surfaces and various linear dimensions.

Description

This utility model relates to technological equipment for the manufacture of building materials, namely concrete blocks with a decorative surface. The mold is applicable for casting blocks based on filled cement compositions, as well as polymer-containing concrete mixtures. The form is designed for products of various lengths and heights, with different surfaces of decorating textures, facial ornaments, images and inscriptions.

The mold contains a pallet and walls with fasteners. To change the geometric proportions of the block, one of the walls of the form is retractable. For a variety of facial textures, a set of removable polyurethane elements with fastening to the sliding wall with bushings or threaded bolts passing through the body of the sliding wall and fixed in the body of removable polyurethane elements is provided. There can be several retractable walls; this allows you to divide the fillable form space into several blocks. Factor-forming removable polyurethane elements, if necessary, can also be placed on the fixed walls of the molds. In this case, blocks with bilateral and tripartite texture are obtained, in particular corner and end blocks.

A significant number of forms are known for the manufacture of decorative concrete and reinforced concrete building products, including building blocks. Known detachable form containing a pallet, walls, fasteners. The transverse sides are connected to the pallet through articulated rods (USSR AS No. 936556). A known form, the transverse sides of which are made in the form of a traverse, pivotally connected by levers with bounding walls (USSR AS No. 984147). The main disadvantages of these forms is a structurally complex and little universal device. A form for manufacturing concrete blocks is difficult to assemble and cumbersome in design (USSR AS No. 435112). It also consists of a pallet, walls and fasteners. Its other drawback is the narrowness of functionality. The same applies to the form (USSR AS No. 727444) containing a frame rigidly fixed by means of eccentric cams. Detachable form of the Russian Federation possesses broader functional capabilities (RF patent No. 2321940). Wide functionality is achieved by the fact that the mold for the manufacture of concrete blocks, in addition to pallets of walls and fasteners, contains a special chamber adjacent to the wall and equipped with a supercharger of decorative mixture. The slot in the wall is blocked by a movable plate. When the form is working, the drawing is applied due to the overlapping of the sliding wall during the drawing process, as well as the injection of the decorative mixture.

The functionality of the form is expanded in comparison with the above analogues. However, the form has a relatively complex structure (additional injection chamber, limited possibilities for decorating blocks). It lacks the means for invoicing blocks in two or more planes with a limited arsenal of means for changing geometry. The purpose of the development of this utility model is to expand the functionality of the form upon receipt of various changes in the geometric dimensions of the product, and decorate them by means of relief formation on the side surfaces of the block, as well as the possibility of manufacturing two or more decorative blocks at once.

This goal is achieved in that in a detachable form containing a pallet, walls with fasteners and a device for applying a pattern, and one of the walls is removable, the removable wall contains a removable invoice surface in the form of a set of polyurethane elements. These elements are a device for applying a picture. The thickness of the concrete block is determined by the position of the movable wall and the removable element, in addition, the shape may have several movable walls with the possibility of changing the distance between them.

Case Studies

Example 1

The mold with a pallet and walls is made with a movable wall of metal, to which a billing element is attached with a surface in the form of wild chipped stone. The block is poured with concrete mixture, after the mixture is hardened and the mold is disassembled, a block is obtained with a face that is textured under the chipped wild stone. The invoicing element is a polyurethane pad.

Example 2

The form with a pallet and walls is made with a movable fiberglass wall, to which a complex fact-forming element with a geometric ornament is attached. The mold is poured with a concrete color mixture. After hardening the mixture and disassembling the form, a block is obtained with a face containing a decorative geometric ornament. The invoicing element is a polyurethane pad.

Example 3

The form with a pallet and walls is made with two movable fiberglass walls, with invoicing elements, the surface of which imitates weathered limestone. The surface of one of the walls may contain an inscription or symbol. Moving the walls relative to each other and filling the resulting space with concrete, a number of blocks are made, which can have both different lengths and different heights due to the level of pouring. In this case, one of the blocks is obtained with two invoiced faces, and two blocks with one invoiced face.

Example 4

The form with a pallet and walls is made with two movable walls, and both walls contain one relief-forming element. At the first stage, the distance between the walls is filled with a composition of one color, at the second stage, the invoicing elements are removed, and the remaining volume is filled with a composition of a different color. Get blocks with shaded, invoiced faces.

A demountable mold for the manufacture of concrete blocks was developed and tested at KTS CJSC during the preparation and execution of work related to the development and manufacture of experimental building structures.

The test results confirmed that the use of the claimed utility model allows:

- to achieve unification of the use of forms, both by changing the relative position of the movable walls, and changing removable decorating elements. In this case, blocks of various thicknesses can be obtained;

- realize the possibility of manufacturing several blocks simultaneously with the same or different surface textures;

- to provide a variety of textures and patterns on the face of the block, to expand the range of products;

- to achieve the possibility of rapid development and changes in the product range due to operational readjustment of equipment in accordance with the claimed samples.

The applicant asks to consider the submitted materials with a view to granting a patent of the Russian Federation for a utility model.
