    DESCRIPTION
    ANTIVIBRATORY RIGID ANCHORAGE DEVICE FOR CONSTRUCTION
    Technical field of the invention
    The present invention corresponds to the technical field of construction.
    Background of the invention
    In the current state of the art there are multiple types of devices for anti-vibration supports, generically called silentblock, to seat machines, installations, structures, etc., on a base, and avoid or limit the transmission of vibrations.
    Most of these devices are simple supports that can transmit vertical actions-reactions to the base, but do not have the capacity to constitute rigid knots. In order to perform a rigid union, the transmission between the machine, installation or structure, and the base, of moments, vertical and horizontal stresses, and torsions, is required by the principle of action and reaction of Physics, which until now involved necessarily also the transmission of vibrations.
    It is necessary to innovate a new device that allows the transmission of moments, vertical forces, horizontal forces and torsions, but not of vibrations; between the machine, installation or structure, and the base.
    Description of the invention
    The present invention consists of a device formed by a steel plate and a plurality of steel anchor bars to leave these anchor bars in a concrete base during their fresh state; characterized in that it has on all surfaces that are in contact with the concrete, an anti-vibration insulating material, such that there is no direct contact between the device steel and the concrete of the base, but that there is indirect contact through this anti-vibration material, which serves to absorb the vibrations and at the same time transmits by pressure the actions and reactions of moment, vertical force, horizontal force and torsion between the elements.
    The dimensioning of the elements of the device, both of the thickness and dimensions of the plate, the number, caliber and length of the anchor bars, the existence or not of profiles in the anchor bars, as well as the thickness and insulating characteristics of the material antivibratory, are determined by calculation; depending on the actions and reactions transmitted between the machine, installation or structure and the concrete base; and depending on the required vibration isolation.
    The invention can be used both for the support of machines and installations, to improve the performance of the simple conventional insulating support or silentblock of the state of the art, as well as for construction structure nodes:

    Depending on the calculation, by means of the device of the invention, knots can be obtained:
    - That transmit action-reaction of vertical force, action-reaction of horizontal force, moment-action-action and torsion-action-reaction.
    - That transmit action-reaction of vertical force, action-reaction of horizontal force and action-reaction of moment.
    - That transmit action-reaction of vertical force and action-reaction of horizontal force, but not action-reaction of moment, allowing a certain rotation.
    - That transmit action-reaction of vertical force, but not action-reaction of horizontal force, nor action-reaction of moment, allowing certain rotation and certain displacement.
    The thickness and insulating characteristics of the antivibration material used are determined by calculation, at each plate position, anchor bars or profiles; in function of the transmission of tensions that the knot requires.
    Description of the drawings.
    In order to complete the description and in order to help a better understanding of the features of the invention, a set of drawings is attached as an integral part of the present specification, in which, with an illustrative and non-limiting nature, the following is represented:
    Figure 1 shows a device of simple conventional support or silentblock of the state of the art, in particular, of those used for the support of a leg of a machine to a base, represented in plan and elevation. This solution manages to reduce the transmission of vibrations from the machine to the base, but the only actions that can be transmitted to the base are the vertical force and a small horizontal force, not being able to transmit momentum and therefore, not being a rigid knot, nor of a recess.
    Figure 2 shows an anchor plate device of the state of the art, of which they are usually used in construction, represented in plants and raised, in two moments, before introducing into the fresh concrete and after having been introduced into the concrete; which is formed by a steel plate (1) and a plurality of steel anchor bars (2). The device is left in the concrete (3) when it is fresh, by different procedures according to the general state of the art; when the concrete is set and hardened, the construction elements (4) are joined to the sheet as a support or steel pillar of the construction in a general non-limiting drawing, the union usually being made with welding to the plate.
    Figure 3 shows the rigid anti-vibration anchoring device of the invention, in a general non-limiting drawing, depicted in plans, elevations and detail, in two moments, before being introduced into the concrete and after having been introduced; which is characterized by a steel plate (1), a plurality of steel anchor bars (2) attached to the plate according to the state of the art, and an antivibrational insulating material (5) covering all the contact surfaces of plate and bars of the device with the concrete of the base. The device is left in the concrete (3) when it is fresh, by different procedures according to the general state of the art; when the concrete is set and hardened, the plate steel is not in direct contact with the concrete that the
