Description

Round reinforcement of lower reinforcements in formwork

Field of the Invention

The present invention relates to an elevator for the round of the lower reinforcements in formwork, especially in lightened formwork for concrete concreting and the like

Background of the invention

Lightened formwork for floors and the like they are generally composed of pieces that delimit channels in one or two perpendicular directions, in which they are arranged the armor the concreting of the nerves of the floor.

The current regulations on obtaining on- site reinforced floor slabs for floors and the like require that the reinforcements remain elevated, with respect to the formwork surface, in order to achieve a perfect concreting that completely covers and surrounds the armor. Otherwise there is a risk that the lower rounds of the reinforcement rest on the surface of the formwork, preventing the entry of concrete between these rounds and said formwork. This problem is especially important in the formwork channels, where the armatures for the slab nerves are arranged.

To meet the regulatory requirement commented is known to provide the pieces with which the formwork of vertical grooves facing the walls that delimit the channels, grooves that are interrupted to a certain distance from the bottom of the channel. Through couples of facing grooves are introduced rods that support inferiorly on the stops that define the internal interruption of the grooves, so that these rods are at a certain distance from the bottom of the channels. The bottom rounds of the reinforcement of the slab nerves rest on the rods facing each other, which will be separated from the bottom of the grooves, thus allowing the concrete to reach said background, completely embedding the armor.

This system, however, requires that pieces from which the formwork is formed have the commented grooves, and then mount the rods between pairs of grooves facing each other. On the other hand, the rods that serve as a stop or support for the lower rounds of the armors must be located in fixed positions, defined by the position of the grooves.

Description of the invention

The object of the present invention is to eliminate the exposed problems, by means of an elevator for the round ones lower armor that can be placed in any point of the formwork channels and that also does not require that formwork parts present conformations for arrangement of said elevator.

In accordance with the present invention, the elevator  it is constituted by a piece in the form of an elongated frame, of length approximately equal to the width of the channels of the formwork This frame can be for example contour trapecial

The cited frame includes two major sides, which would correspond to the trapezoid bases, one in position lower and another in upper position. The bottom side is intended to support transversely on the bottom of the canal and this externally equipped with a central core, which will be housed in a recessed presenting the bottom of the canal. The upper side of the frame will define the support surface of the lower rounds of the armor This upper side will preferably be equipped, along it, from a series of external projections that serve as round dividers.

If the frame takes the form of a trapeze, as indicated, will be arranged in the formwork channels in position inverted, that is to say with the smaller base resting on the bottom of the channel and protruding from it the nucleus mentioned above, while that the major base will constitute the upper side of the frame, from which protrusions protrude and on which the rounds will rest lower armor.

The framework with the constitution commented can go reinforced by intermediate transverse partitions.

The frame that configures the elevator of the invention can be placed in the formwork channels in any  point, since it will be enough to introduce it, so that one of the larger sides rest on the bottom of the channel, the other side being with the highlights directed upwards, to serve as support of the lower rounds of the armor.

The height of the frame will correspond to the height at the one that want to place the bottom rounds with respect to the bottom of the formwork grooves.

Brief description of the drawings

The feature and advantages of the elevator invention may be better understood with the following description made with reference to the attached drawings, in which It shows a non-limiting embodiment.

In the drawings:

Figure 1 is a front elevation of a separator constituted according to the invention.

Figure 2 is a bottom floor of the separator of figure 1.

Figure 3 is a side elevation thereof separator.

Figure 4 shows in perspective a piece of traditional constitution for formwork lightened up

Figure 5 is a section of the same piece, according to the V-V cutting line in figure 4.

Detailed description of one embodiment

Figures 1 to 3 show an elevator for round reinforcement in formwork, constituted in accordance with the invention, which is constituted by a piece 1 in the form of frame that in the example represented in the drawings adopts contour Isosceles trapecial. Between the major 2 and minor 3 bases run transverse reinforcement partitions 4. From the main base 2 protrude outwardly, in coincidence with the partitions 4, projections 5 that are located in an equidistant position, meanwhile, of the base smaller 3 a central core 6 protrudes than in the example shown in the drawings is wider than frame 1. As can be best seen in Figure 3 of the surfaces of the nucleus 5 parallel to frame 1 small nerves or fins protrude 7.

A piece 8 of general constitution known for formwork lightened up These pieces can define a single channel or two channels 9 and 10 perpendicular, as in the example shown, in al form the formwork will serve for the concreting of the nerves of the forged, in which the corresponding ones will be previously arranged armors

In order that the bottom rounds of the armors are separated from the bottom 11 of the channels, in the pieces like the one depicted in figures 1 are introduced 3, to serve as elevators of the lower rounds of the armors

As can be seen in figures 4 and 5 the piece 1 is placed in transverse position in channels 9 and 10, with minor base 3 directed down and major base 2 directed upwards. The core 6 is inserted in housings 12, figure 5, which present pieces 8 from the bottom of channels 9 and 10, thus ensuring the position of the pieces 1. The protrusions 5 are directed upwards to serve as elements separators of the lower round of the reinforcements, which they will rest on the upper base 2 of the separator. In this way the round are separated and separated from the bottom 11 of the channels 9 and 10, ensuring the entry of concrete between said rounds and the bottom of the channels.

The nerves or fins 7 of the nucleus 6 will serve to  ensure the position of the separators preventing their exit accidental accommodation 12.

As can be seen in Figure 5, the pieces  8 may have light surfaces on the bottom surface recessed 13, coinciding with the accommodations 12, which they will serve to indicate the position of the cores 6 in the floor, once formed this one. In this way the cores 12 can be used then for fixing elements that may be suspended of the roof.

Piece 1 can be made of material plastic or metallic and, as stated above will meet the double function of acting as elevators and round separators lower armor and for anchoring elements that they must be suspended or fixed on the ceiling, for example for clamping of all types of cover plates, elements hung, etc.

As can be understood, the frame or piece 1 can  adopt a different configuration than described, for example rectangular, and also the core 6 can be of configuration prismatic, cylindrical, etc.

The maximum length of piece 1, which in the example depicted in the drawings will correspond to the length of the major base 2, will be approximately equal to the width of the channels 9 and 10 of the pieces 8.
