Abstract:
At least some embodiments of the present disclosure provide a roofing accessory that includes a radiofrequency radiation shielding non-woven fiber composite material. The radiofrequency shielding non-woven fiber composite material includes a first fiber type that includes a conductive material, where the radiofrequency shielding non-woven fiber composite material has a sufficient amount of the first fiber type so as to result, when the radiofrequency shielding non-woven fiber composite material is positioned on a roof structure, in the radiofrequency shielding non-woven fiber composite material allowing for shielding a predetermined percentage of electromagnetic radiation passing through the roof structure. The radiofrequency shielding non-woven fiber composite material includes a second fiber type that includes a non-conductive material. The first fiber type and the second fiber type are randomly dispersed within the radiofrequency shielding non-woven fiber composite.
Abstract:
Un bloque deslizante compuesto para disponer entre dos placas de soporte de un aislador sísmico de tipo friccional con una placa de soporte conectada a la superestructura a aislar y la otra a fundaciones, comprende dos componentes de contacto que están, por lado externo, en contacto deslizante o articulado con dichas placas de soporte según el aislador sea de una o dos superficies deslizantes y, por lado interno, acoplados entre sí vía una proyección macho de un componente en un rebaje hembra del otro. Un sello elastomérico ocupa un espacio vacío circundante a la proyección en el rebaje y, en el lado externo de él(los) componente(s) de contacto en contacto deslizante con la(s) placa(s) de soporte(s), una placa de deslizamiento está acomodada en un correspondiente nicho con un soporte elastomérico de compresión en el fondo. Unos aisladores tipo péndulo friccional de una o dos superficies deslizantes cóncavas incluyen dicho bloque.
Abstract:
The invention relates to a prefabricated construction element (1) comprising a bulk element (5) having a front surface (7) and a ack surface (9), extending parallel with each other, defining a thickness (11) thereof, wherein at least one side surface (13) extends between said front and back surfaces (7, 9). The construction element (1) further comprises at least one plate element (5), arranged to cover at least the front surface (7) of the bulk element (5), being in direct contact thereto. Each plate element (15) have a thickness (17) and/or is made of a material that provide electromagnetic shielding to the construction element (1), defining an electromagnetic shielded area (19) thereof. Furthermore, each edge (21) of the at least one plate element (15), which edge (21) is aligned with a circumference (23) of the electromagnetic shielded area (19), comprises at least one flange element (25), extending a predetermined distance (27) from said circumference (23), in a direction away from the electromagnetic shielded area (19) and into the bulk element (5). Wherein an outer surface (29) of said at least one flange element (25) is aligned with a plane defining any surface adjacent the circumference (23) of the electromagnetic shielded area (19). The invention further relates to a method for manufacturing such a construction element (1).
Abstract:
A barrier system comprising: an elongate and rigid base member having a channel defined by inner walls of the base member, the channel extending along the length of the base member, the rigid base member being adapted to be anchored to an underlying supporting surface wherein the channel comprises a relatively broader in-use lower portion with a first width (w1) and a relatively narrower in-use upper portion with a second width (w2) defining an opening into the channel; and a removable wall assembly adapted to be removably fastened relative to the base member, the removable wall assembly comprising a flexible barrier wall having a length and a height and being adapted to be positioned within the opening of the upper portion of the channel wherein the wall assembly comprises a frame assembly for framing the barrier wall, the flexible frame assembly further comprising a top frame member and a bottom frame member with the height of the flexible barrier wall extending therebetween and wherein the bottom member is dimensioned to have a thickness that is less than or equal to w1 and that is greater than w2 for allowing the bottom member be received into the lower portion of the channel to position the flexible barrier wall in a substantially upstanding position and for simultaneously preventing the bottom member from being passed through the opening defined by the upper portion of the channel in an upwardly direction.
