Abstract

The solution relates to the construction industry and can be used for the manufacture of concrete products. It is proposed for the manufacture of products such as pillars with grooves in height, the hollow formers to fasten with fasteners to the corresponding wall of the mold body through the matching holes in the walls of the housing and the liner, to provide the hollow formers with covers made of material with low adhesion to concrete, the mold body to be made of metal, which will provide strength, hollow formers - made of wood, and the liner is made of polymeric material. This ensures high manufacturability of the mold by simplifying its assembly and disassembly. facilitates the form and eliminates the sticking of concrete to the elements of the form. 1.p., 3 s.p. f-ly, 1 ill.

Description

The solution relates to the construction industry and can be used for the manufacture of concrete products.

A known form for the manufacture of building products containing a pallet, sides, a removable lid, a composite tubular hollow core installed in the middle part of the mold with the formation of a cavity with porous walls and at least two transverse through channels (RF patent No. 2113986, B28B 7 / 00, B28V 7/10, published on June 27, 1998). The disadvantage of this solution is that it is possible to displace parts of the core while pouring concrete.

As a prototype, a form has been adopted for the manufacture of decorative facade concrete products (RF patent No. 2245784, B28B 1/14, B28B 7/02, SOCHV 28/02, SOCHV 7/52, publ. 02/10/2005). The form contains a housing in which a liner (matrix) is installed, forming the surface of the product, at least one hollow core, fixing elements.

The case can be made in the form of a box made of concrete, gypsum, wood concrete, magnesia binder and wood sawdust, hollow formers - from laminated plywood or gypsum or metal. The material of the liner is not mentioned in the patent. The insert is fixed with struts, wedges, plates and metal rods. In the concrete layer of the housing there is a reinforcement with outlets (handles) protruding from the transverse walls - for transporting the mold. There are also metal rods built into the concrete layer of the mold for fixing the forming insert and attaching the holders.

The disadvantage of the mold is that it is very heavy, its manufacture is laborious, the installation of carrying handles and fasteners in the concrete case is laborious, and it is difficult to remove them for changing the mold to another type of product, because there will already be a different arrangement of holes. It is possible for concrete to adhere to hollow formers, which makes it difficult to remove them.

These shortcomings are eliminated by the proposed solution.

The problem to be solved is the creation of a mold for the manufacture of concrete products such as pillars with grooves in height.

The technical result is an increase in the manufacturability of the mold due to the simplification of its assembly and disassembly, facilitation, the exclusion of concrete sticking to the mold elements.

This technical result is achieved in that in a mold for the manufacture of concrete products, comprising a housing with a base, longitudinal and transverse walls, in which an insert is installed that forms the surface of the product, at least one void forming agent, liner and void forming agent latches, cover, handles for transportation, for the manufacture of products such as pillars with grooves in height, hollow formers with covers made of material with low adhesion to concrete mounted on their working surface are fixed with fasteners to The appropriate wall of the housing through the coinciding openings in the walls of the housing and the insert, and the handles for transporting affixed to the base and the lid by gussets;

the casing is made of metal, the hollow formers are made of wood, and the inserts and covers of the hollow formers are made of polymeric material (plastic).

The placement of hollow formers in plastic covers makes it possible to make hollow formers from any available materials, their fastening facilitates assembly and disassembly of the mold, fastening the handles for transporting not only the mold as a whole, but also the lid separately, does not affect the interior of the case and there is no need to make extra holes in the walls , which would reduce the strength of the form, in addition, the scarves of the lid play the role of guides when putting it on the body. The selection of materials makes the form easier, without reducing its strength.

The proposed form is shown in the drawing. It contains a metal housing 1 with a base 2, longitudinal and transverse walls. In the housing 1, an insert 3 of polymer material is installed, forming the surface of the product. Voids (grooves, holes) in the product are formed by hollow formers 4, the number of which is selected by the number of grooves that need to be formed. Void formers 4 can be made of available materials, such as wood. They are placed in covers 5, which, being made of a material with low adhesion to concrete, in particular plastic, exclude the sticking of concrete and make it possible to use various materials for the manufacture of the hollow formers themselves. So that the covers 5 do not fall off, they can be fixed with stapler brackets. The hollow formers 4 are fixed by means of fasteners 6, for example, screws to the walls through matching holes in the walls of the housing 1 and the liner 3 as well as to the cover 7. The cover 7 is equipped with handles 8 for transportation to which

the kerchiefs 9 are attached, which are also guides when putting it on the case 1. The handles 10 by means of the kerchiefs 11 are also attached to the base 2 and to the wall of the case 1, forming a stretcher. Support elements 12 are attached from below to the base handles - for ease of installation on the floor or on the rack and, accordingly, lifting, and on the handles 8 and 10 there are stops 13 that prevent slipping of the hand. In the form, if necessary, fittings 14 and pipes 15 for lighting wires can be installed.

The form is collected as follows.

The case 1 is installed on the table, the insert 3 is placed in it and the hollow formers 4 are installed, fastened with screws 6. They put covers 5 on the hollow formers 4, and they are fixed with staple brackets. If necessary, fasten to the base 2 reinforcement 14 with pipes 15 attached to it for lighting wires. The concrete mixture is poured with the cover removed 7. The form is filled taking into account the number of void formers 4. If they are only on the side walls, then the form is completely filled. If there is a void-forming agent on the lid, then the form is not completely filled out, but taking into account the volume of this void-forming agent. When closing the lid 7, he will squeeze out the excess mass of concrete in the free space to the lid.

The concrete mixture with the lid 7 closed is sealed on a vibrating table for 2-5 minutes.

After molding is completed, the mold is transferred to the rack where it is kept for one day at room temperature.

After a day, form stripping is carried out. The lid 7 is removed, then the fasteners 6 are removed, the mold with the product is turned over by the handles 10 and the plastic insert 3 easily leaves the housing 1 under its own weight. It is also easily removed from the product. Void formers 4 are removed together with covers 5. The product is ready for use, and the mold is ready for the next cycle of work. Moreover, all components of the form do not require lubrication before further use.

Thus, a universal collapsible mold design was created for the manufacture of concrete products with grooves in height.
