Description

Soporte regulable en altura para suelos huecos.Height-adjustable floor stand gaps

El objeto de la presente invención consiste en un soporte regulable en altura para suelos huecos, el cual está constituido por un núcleo con rosca exterior y al menos una placa con rosca interior conjugada con dicha rosca exterior.The object of the present invention consists of a height-adjustable support for hollow floors, which is constituted by a core with external thread and at least one plate with internal thread conjugated with said external thread.

Los soportes regulables en altura para suelos huecos se fabrican hasta ahora a base de metal y presentan generalmente una placa unida sólidamente con el núcleo central y una segunda placa provista de rosca interior, de modo que dichos soportes son regulables en altura. Estos soportes regulables en altura adolecen del inconveniente de que, en caso de incendio, pierden rápidamente su estabilidad y, por tanto, la función de apoyo para las placas del suelo hueco colocadas encima. Asimismo, estos soportes de metal están en condiciones de transmitir el sonido, especialmente el sonido de las pisadas, al suelo inferior. Por último, los soportes conocidos hasta ahora tienen que protegerse contra la corrosión.Height-adjustable floor stands gaps are manufactured to date based on metal and present generally a solidly bonded plate with the central core and a second plate provided with an internal thread, so that said stands are height adjustable. These adjustable brackets in height suffer from the inconvenience that, in case of fire, they quickly lose their stability and therefore the function of support for hollow floor plates placed above. Likewise, these metal brackets are able to transmit the sound, especially the sound of footsteps, to the bottom floor. Finally, the supports known so far have to be protected against corrosion

La invención se ha planteado el problema de proporcionar soportes regulables en altura para suelos huecos que presenten también un núcleo con rosca exterior y al menos una placa con rosca interior conjugada con dicha rosca exterior, los cuales conservan su estabilidad incluso en caso de incendio, garantizan un mejor aislamiento acústico y no tienen que protegerse contra la corrosión.The invention has raised the problem of provide height-adjustable supports for hollow floors that also have a core with an external thread and at least one plate with internal thread conjugated with said external thread, which they retain their stability even in case of fire, guarantee a better sound insulation and do not have to protect against corrosion.

Este problema se resuelve según la invención por el hecho que el núcleo y la placa consisten en yeso fraguado reforzado con fibras, presentando el núcleo un diámetro de 70 a 120 mm y teniendo la placa una altura de 25 a 50 mm, así como una longitud de sus lados 110 a 220 mm. Preferiblemente, el diámetro del núcleo es de 80 a 100 mm y la placa presenta una altura de 30 a 45 mm y una longitud de sus lados de 130 a 180 mm.This problem is solved according to the invention by the fact that the core and the plate consist of set plaster reinforced with fibers, the core having a diameter of 70 to 120 mm and the plate having a height of 25 to 50 mm, as well as a length of its sides 110 to 220 mm. Preferably, the diameter of the core is 80 to 100 mm and the plate has a height of 30 to 45 mm and a length of its sides from 130 to 180 mm.

La placa es preferiblemente de configuración cuadrada, pero puede ser también, sin dificultades, de configuración rectangular o poligonal.The plate is preferably of configuration square, but it can also be, without difficulties, of rectangular or polygonal configuration.

En estas placas de yeso fraguado reforzado con fibras se cortan agujeros con rosca interior. La rosca puede ser una rosca trapecial, pero preferiblemente una rosca pendiente de sierra, ya que esta última hace posible que la carga que gravita sobre el suelo hueco se distribuya mejor hacia el soporte. El núcleo de yeso fraguado reforzado con fibras se fabrica preferiblemente de tal manera que una placa prensada correspondientemente gruesa es cortada en bloques largos que se tornean seguidamente formando columnas en las que se talla después una rosca exterior conjugada con la de la placa. Sin embargo, en principio, es posible también fabricar las columnas y las placas por colada de masas fraguables que contienen fibras, consistentes en \alpha- y/o \beta-semihidrato, así como anhidrita. En particular, son adecuadas la anhidrita natural finísimamente molida con d_{90} \approx 8 \mum o sus mezclas con \alpha/\beta-semihidrato. Para fabricar un núcleo por el procedimiento de colada se vierte, por ejemplo, el componente aglutinante acuoso en una matriz adecuada y, después del endurecimiento, se retira la matriz, por ejemplo por abatimiento hacia arriba. El núcleo puede ser entonces extraído.In these plasterboard plates reinforced with Fibers cut holes with internal thread. The thread can be a trapezoidal thread, but preferably a pending thread of saw, since the latter makes it possible for the load to gravitate on the hollow floor it is better distributed towards the support. The nucleus of fiber reinforced reinforced plaster is preferably manufactured from such that a correspondingly thick pressed plate is cut into long blocks that then turn forming columns in which a conjugated outer thread is then carved with that of the plate. However, in principle, it is also possible manufacture the columns and plates by casting of fragable masses containing fibers, consisting of α- and / or β-semihydrate, as well as anhydrite. In In particular, the finely ground natural anhydrite is suitable with d_ {90} \ approx 8 \ mum or mixtures thereof with α / β-semihydrate. To make a core by pouring procedure is poured, for example, the aqueous binder component in a suitable matrix and, after hardening, the matrix is removed, for example by abatement upwards. The core can then be extracted.

En principio, es posible aplicar al núcleo con rosca exterior, tanto por arriba como por abajo, una placa con rosca interior correspondiente. Sin embargo, en la práctica, es suficiente que solamente un extremo del núcleo se atornille en una placa con rosca interior conjugada para realizar así el ajuste en altura. En el otro extremo del núcleo puede preverse, por ejemplo una placa de asiento y ésta puede ser atornillada o pegada con el núcleo.In principle, it is possible to apply to the core with external thread, both above and below, a plate with corresponding internal thread. However, in practice, it is enough that only one end of the core is screwed into a plate with conjugated internal thread to make the adjustment in height. At the other end of the core can be provided, for example a seat plate and it can be screwed or glued with the core.

Asimismo, es posible aplicar la placa con la rosca al extremo inferior del núcleo y realizar en el extremo superior del núcleo una escotaduras en las que se inserten varilla conjugadas con ellas a base de yeso fraguado reforzado con fibras. Es posible así construir a partir de piezas prefabricadas de igual tamaño una celosía de yeso fraguado reforzado con fibras que confiere una estabilidad y capacidad de carga sensiblemente mayores a las placas sobrepuestas del suelo hueco. En tanto estas varillas estén configuradas en forma extraíble, es posible también en cualquier momento que, después de retirar las placas de cubierta, se realicen trabajos sin impedimentos en las cavidad existente debajo de ellas y se coloquen o modifiquen las conducciones. Las distancias entre los soportes regulables en altura según la invención corresponden preferiblemente a las dimensiones de las placas de cubierta. En caso de que el suelo hueco deba ser sometido a una carga especialmente grande o bien las dimensiones de la placa de cubierta sean especialmente grandes, se pueden utilizar también, por supuesto, menores distancias entre los soportes.It is also possible to apply the plate with the thread to the lower end of the core and perform at the end upper of the nucleus a recesses in which rod are inserted conjugated with them based on hardened fiber reinforced plaster. It is thus possible to build from prefabricated parts of the same size a lattice of reinforced plaster reinforced with fibers that confers significantly greater stability and load capacity to the overlapping plates of the hollow floor. In both these rods are removable, it is also possible in any time that, after removing the cover plates, work without impediments is carried out in the existing cavity under them and the pipes are placed or modified. The distances between the height-adjustable brackets according to the invention preferably correspond to the dimensions of the cover plates. In case the hollow floor must be submitted at a particularly large load or the dimensions of the plate of cover are especially large, can also be used, Of course, shorter distances between the supports.

Por tanto, los soportes regulables en altura según la invención se pueden utilizar de forma muy versátil y flexible y, entre otros sitios, se pueden aplicar allí donde los suelos huecos deban exponerse a cargas especialmente altas, por ejemplo por el peso de carretillas elevadoras.Therefore, height adjustable brackets according to the invention they can be used in a very versatile way and flexible and, among other sites, can be applied where hollow floors should be exposed to especially high loads, for example by the weight of forklifts.

Una forma de ejecución típica del soporte según la invención consiste en una columna de 150 a 300 mm de longitud a base de yeso prensado reforzado con fibras con un diámetro de 90 mm, en la cual se ha tallado por fuera un rosca trapecial o una rosca en dientes de sierra, y dos placas cuadradas con las dimensiones 150 x 150 x 35 y un agujero central con una rosca que casa con la de la columna. Las dos placas se atornillan y ajustan en altura en los extremos superior e inferior de la columna. En caso deseado, estas placas se fijan en este ajuste mediante pegado de la rosca.A typical form of support execution according to the invention consists of a column of 150 to 300 mm in length at fiber reinforced pressed plaster base with a diameter of 90 mm, in which a trapezoidal thread or a sawtooth thread, and two square plates with the dimensions 150 x 150 x 35 and a central hole with a thread that house with the one in the column. The two plates are screwed and adjusted in height at the upper and lower ends of the column. In If desired, these plates are fixed in this setting by gluing of the thread
