Description

Formwork mold extraction device for burial niches of variable width.

Object of the invention

This utility model refers to a formwork mold extraction apparatus for niches burial of variable width.

Background of the invention

Currently the methods used for the construction of burial niches require the construction of a land containment wall. Then, the niches are made of brickwork, which entails sealing problems, both gases and liquids produced during corpse rot.

Therefore, the construction of the Burial niches in concrete. The niches manufactured according to the invention are based on a modular formwork that is placed on the place where the niche will be, and that serves to contain the concrete for the duration of setting. To prevent the  concrete sticks to the formwork walls, a release agent on all sides of the formwork that They will be in contact with the concrete.

Once the concrete has set, shaping the Niche itself, the mold must be removed formwork Until now, there were width extraction devices fixed, which only allowed the removal of the formwork mold in niches of a certain width. However, niches are common of different widths, which implies a problem during formwork mold removal. This problem is solved. by means of the extraction apparatus according to the invention, which You can extract molds of different widths.

Description of the invention

Therefore, according to the invention, provides a formwork mold extraction apparatus for niches of variable width, of the type that fit the mold of recoverable formwork that shapes the concrete that makes up the niche walls This device is characterized because it is constituted by a resistant structure in the form of "U", at less one of whose lateral branches can slide transversely with respect to the central branch by means of a sliding guide inside said central branch of the "U", fixing to this by means of a pin that can be attached in different positions corresponding to different holes that cross the central branch and sliding guide. This structure constitutes a support body of a hydraulic cylinder that is mounted on the branch central of the "U", and that supports its lateral branches in the Niche front sides. The rod of this cylinder it has parallel protruding lugs at its free end between which a flat projection of the structure of the mold, fixing this coupling with another pin. So by cylinder effect the mold is extracted a necessary length and enough to carry out the demoulding.

Therefore, how to use the device Formwork mold extraction would be as follows. In first instead, the branch or lateral branches are slid until the "U" has the desired width to fit the niche in issue, fixed by the pin. Then it is extracted the hydraulic cylinder and attaches to the flat projection of the mold structure. Finally, the cylinder is operated hydraulic, which exerts a force on the formwork mold and what move out a sufficient distance to continue manually with the extraction.

Brief description of the drawings

Fig. 1 shows a plan view of a apparatus according to the invention, in which only one of the Side branches is sliding.

Fig. 2 shows a perspective view of a  apparatus according to the invention, in which the sliding mechanism of the lateral branch.

Fig. 3 shows in more detail the mechanism  of sliding of the lateral branch.

Description of a practical embodiment of the invention

The apparatus consists of a structure 2  U-shaped, one of whose lateral ends 3 is fixed and the other mobile 14, in the case of this embodiment. He mobile end 14 can be displaced transversely because it has a guide 16 that slides inside the central branch 5 of structure 2, and that can be fixed in different positions by means of a pin 15 that is inserted into holes 13 practiced in the central branch 5 of structure 2 in the form of "U" and in the guide 16 of the mobile end 14.

The central branch 5 of the structure is mounted a hydraulic cylinder 6, whose rod 7 has at its free end two lugs 8 that fit a projection 9 of the mold. This Coupling is done by a pin 11.

So, the hydraulic cylinder, after engage the projection 9 of the mold, retracts outward, leaning the structure on the front face of the niche in the 4 ends of the side branches, and remove the front of the mold a sufficient distance to complete the extraction manually easily.

Fig. 1 shows the mold already extracted until the stop, since the front part 12 of the mold is in contact with the central branch 5.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
