Abstract

An equipment of immobilizing iron armature which consists of a point (2) of deposing iron armature and protrusions (8) of sustaining the armature to its position. This equipment is incorporated inside the concrete and has the property to sustain the iron armature of concrete in the position which is set by the drawings in any shear may be required, since this component has been already defined to have the iron rods at every two centimeters, which is the less allowed limit existing that the iron is used inside concrete, this means that it covers all the specifications of projects and that it is suitable for all kinds of armatures. The advantage of this invention is that for a slab of concrete of 100 square meters with 12 beams and 14 pillars there should be needed almost 6000 to 7000 bindings. With this equipment there would be needed 100 to 200 bindings. While by binding it is not certain that the iron rods will remain in their positions, using the equipment of immobilizing the iron armature this can be secured.

Description

IMMOBILIZATION EQUIPMENT FOR IRON ARMATURE

This invention presents an immobilization equipment for iron armature inside the concrete in the specific point which is being asked by any different requirement of a certain plan of work.

The method up to now, goes as follows: we place plastic or concrete spacers or even iron ones in order to lay the iron armature in special depth inside the concrete as it is indicated by the drawings, e.g. any five centimeters or any ten or any fifteen. Afterwards according to the traditional way, accepted until nowadays, we bind the iron armature using wires in order to make certain that it will stay stable to the position given in the drawings. Consequently many bindings are needed in order to stabilize the armature in the position set by the drawings at the moment the concrete is falling through the compressing press and being throbbed at the same time by the penetrating equipments inside the concrete. Thus many working hours are needed in order to bind the armature and to make sure that it will stay at its position, considering that in a 5 meters iron rod we make six bindings. We should also bear in mind that a 100 square meters slab of concrete needs about 6.000 to 7.000 bindings.

Placing the immobilization equipment for iron armature by one meter between them that is for the first layer of iron rods gives us the advantage to use it at the same time as a spacer of special depth inside the concrete whereas it has openings every two centimeters, which is the less distance allowed between the iron rods. We lay the iron rods in the openings, that is every 2 cm or every 4 or every 6, generally in multiples of 2, preparative to full implementation of the drawings of the project. The iron rods are immobilized to the position where we lay them and thus, they do not need binding. In order to lay the second layer of iron to the vertical side of the first layer and create a grillage, we place the equipment of immobilizing iron in parallel with the first layer every 1 meter and we lay the iron rods to the openings in distances indicated by the plan and they are also immobilized.

The immobilization equipment for iron armature according to the present invention has the following characteristic, that is when the armature is placed at the special point indicated by the drawings, it does not need any binding to stay in place. A simple way to introduce the equipment is that every two centimeters there is the point (2) of laying the iron armature according to the Φ of the iron, protrusions (8) of holding the iron armature which is should have relative height and space between them so as to be able to function with every Φ of iron rods from Φ.8 up to Φ.40. It is also advisable for the first layer of iron that the equipment will function also as a spacer of the specific depth of the armature inside the concrete, thus avoiding placing spacers and reducing the cost. In a few words, placing the equipment of immobilizing the iron armature even as a spacer, we can place the iron rods straight onto the opening suggested by the drawings and immobilize it to its position in less time and with less working hours, which consequently is decreasing the cost.

The present invention can be fully placed following below detailed description regarding the attached drawings, in which we analyze the accurate method of their function.

In figure 1 we can see a perspective view of the immobilization equipment of iron armature, a general view (1 ), point (2) for iron armature laying, protrusions (8) for holding the armature, flaps (12) to keep the armature held in position.

In figure 3, there is a perspective view of the immobilization equipment of iron armature, concerning to the first layers of iron and which functions as a spacer of special depth into the concrete. The difference of this component is that there is an opening (3), which allows concrete to get through and gaps (4) allowing concrete to get through and thus there will not be any interruption of concrete flow (pre-breach). Figure 12. It shows a perspective of a component for immobilizing iron armature concerning beams and pillars. This component has the following characteristic that placing the armature iron on point (2), it is also placed the additional component (6) on the protrusions (8), which penetrate the holes (5) by pushing until the additional component (6) touches the iron rods and stays at its position by the flaps (12), which are on the protrusions (8).

From figure 1 until figure 13, it would be advisable according to the invention, to be made out of plastic, which means that the manufacturing of the component is easy and productive. Besides figures 12 and 13, the rest could be made in any length is convenient, that is 1 meter, 1 ,50 or

1 ,80 or 2 or 3 meters, while figures 14, 15, 16 and 17 could be made according to the invention by galvanized steel sheets of 1 millimeter to 2 millimeters while all the additional components should be made of plastic.

It would also be advisable, according to the invention that the equipment should not have lugs (1 1 ) and so to make some bindings of the structural iron with the equipment, which will be cheaper. Following the invention, the component should also not have protrusions (8) on the one side, and thus be even cheaper. It would also be advisable the lugs (1 1 ) run all over the length of the component.

Figures 18 - 19 - 20 show the perspective views of the additional equipments which are meant to connect the equipment of iron armature immobilization. Figure 18 fits to the following additional equipment " 1, 2, 3, 4, 5, 11 ". Figure 18 would be advisable to become in two sizes, one to be on its own and one bigger to fit additionally to figure 19 and also to figure 20 for bigger safety. Figure 19 also fits to the following figures "1 , 2, 3, 4, 5, 11 ". Figure 20 fits to the figures "1, 11 ". The method of these additional components is the following: when you put two immobilization equipments of iron armature consecutively, then you put the additional component (31 ) and you button it to the (32).

It is advisable according to the invention that those additional components not to be necessary, due to the fact that by a slight parallel overlapping of the components to achieve the required result.

Claims
