Description

(57) The mold (1) for manufacturing the components (8) is provided with sliding slide elements (6) for easy demoulding. The sliding slide elements (6) are provided with openings (61) in which the protruding ends (71) of its longitudinal reinforcements (7) are disposed during manufacture of the component (8).

Technical field

The invention relates to an improvement of a mold for the production of reinforced concrete components, in which the easier molding and demolding of the components is solved.

BACKGROUND OF THE INVENTION

Tilting and folding forms are known and mostly used for the production of reinforced concrete components. The tilting molds are designed to allow easy and safe tilting using a tilting device. Handling the mold during demolding of the finished part is demanding from the point of view of work safety and in case of operator errors the demolded products are relatively damaged. The folding forms, which are more complicated in construction than the folding ones, make it possible to reliably demould the finished product, but they are labor intensive and expensive because of their considerable weight. In order to overcome these drawbacks, a lightweight, structurally simple mold has been developed which is divided into walls and in-line rows for individual molded parts, and in its bottom there are rows of release openings through which parts of the reinforcement protrude in the formed state. parts in the outside of the mold. This allows removal of the finished part in a manner in which the mold and the parts are pressed against a rigid support placed in the space below the protruding reinforcement. The main drawbacks of this form are that a considerable force is required for demoulding, which must be applied against a rigid backing, which negatively affects the quality of the parts, and in some cases their integrity is compromised. The molds also do not allow the construction and demolding of a component in which its longitudinal reinforcement is required to extend in the longitudinal direction of the front of the component on one or both sides.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages are overcome by the mold for the production of reinforced concrete components according to the invention, characterized in that sliding slide elements whose cross-section is identical to the cross-section of the component are arranged in the space of the tapered transverse walls of the mold frame. The sliding elements are provided with openings of circular or other cross-section in which the protruding ends of their longitudinal reinforcements are located in the manufacture of the components.

The design of the sliding element mold according to the invention substantially reduces the amount of force required for demoulding and consequently eliminates the cause of deformation and the integrity of the molded parts. A further substantial advantage of the mold according to the invention is that it allows the molding of such parts where the longitudinal reinforcement is required to protrude on the faces of the parts. Thus, the invention has the consequence of saving labor and cost in assembling components on construction sites.

DETAILED DESCRIPTION OF THE INVENTION

The mold 1 is provided with chamfered longitudinal walls 2 and transverse walls 1 within the frame 11, between which fixtures 4 are fixed which define in part the shape of the molded part 8. In the bottom of the film 1, release openings 51 are formed above them. In the space of the tapered transverse walls 2 within the frame 11 of the mold 1, slide-out sliding elements 6, in a particular embodiment of sheet metal, the thickness of which is equal to the desired length of the protruding ends 71 of the reinforcement J, are displaceable. the sliding element 8 has a shape identical to the cross-section of the panel 8 and is provided with four circular holes 61.

In forming the workpiece, the reinforcement 2 is first deposited so that the ends 71 of their longitudinal members are threaded on both sides into the openings 6 of the sliding slide elements 6. The sliding slide elements 6 are inserted with the reinforcement 2 into the mold 1 so that parts of the reinforcement extend into the through holes 41 and thus protrude into the spaces below the built-in units. After filling the mold with concrete mixture, a conventional compaction and maturation procedure of the building component follows. Deforming

3 is carried out in such a way that the mold 1 with the blade 8 is lowered against a fixed insert (not shown) located in the space 1i by the protruding transverse reinforcement. As the mold 1 gradually descends, the grip 8 is released from the mold 1 upwardly, the grip 8 being molded with the slide-out sliding elements 6, which are removed from the faces 81 of the grip 8 after completion of the molding. 81 bars 8 projecting ends 71 longitudinal bars of reinforcement 2 ·

Industrial applicability

Porma poile of the invention enables economically advantageous production of reinforced concrete building blocks, especially of linear shape, in all areas of the building industry. The invention finds particular application in modular and obobial systems which require that a part of the reinforcement protrude from the assembly outside the hilt.
