Parquet multicapa de Eucalyptus globulus y Quercus robur . resistencia al impacto para diversas tipologías de fabricación

Abstract

Utilizando el test de impacto, basado en la norma ASTM D1037-99, se compara la resistencia de diversas composiciones de fabricación de parquet multicapa de Eucalyptus globulus y Quercus robur, con distintos espesores de capa noble y utilizando para cada uno de ellos tres tipos diferentes de soporte base con el propósito de evaluar la aptitud de Eucalyptus globulus como parte destacada (capa noble) en la elaboración de un parquet multicapa. El resultado del ensayo de impacto resultó ser estadísticamente independiente de la especie utilizada (eucalipto o roble) como capa noble, habiéndose analizado con niveles de significación superiores al 95%, siendo, sin embargo, dependiente del tipo de elemento de soporte utilizado y del espesor de la capa noble. Un modelo lineal, que utiliza la densidad media en los 4 primeros milímetros de profundidad de cada pieza, permitió explicar hasta un 82% de la variación del diámetro de huella en el ensayo de impacto, lo que permite utilizar con suficiente garantía esta densidad como predictor del diámetro de huella del ensayo de impacto.. Palabras clave: Dureza, eucalipto, pisos de ingeniería, resistencia al impacto, roble.

The Ball Response on the Beech Parquet Floors Used for Basketball Halls

“…All type B structures had a good ball reaction above the minimum acceptable value of 1.0836 m. The energy absorption of the three types of structures with values of 6.61, 6.00, and 1.88% was lower than the limiting energy value of 6.69%, which means that from this point of view, all type B structures are acceptable for use in the case of basketball halls. Similar results were observed by Acura et al [18] by using eucalyptus wood, Same values were also sfound by Sepliarsky et al [8], where oak wood was used.…”

“…Kolitzus [6] highlighted the role of sports floor testing facilities and proposed a series of tests that are currently found in European standards EN 14 808 and EN 14809. Other wood species such as sugar palm (Arengapinnata) [7] or Eucalyptus globulus [8] were tested. Basketball floors must meet the requirements of standard SR EN 12235:2014) [9].…”

“…The tests were performed according to SR EN 12235 [9]. Sepliarsky et al [8] highlighted the importance of strength for the two types of floors made of Eucalyptus globulus and oak (Quercus robur), using the impact test according to ASTM D1037-99. Ayata et al [28] in their study performed tests on different thermal aging regimes (30 • C for 30 days, 60 • C for 60 days, 90 • C for 90 days) for beech, maple, and oak parquet structures.…”

Establishment of Quality Classes for Hardwood Floorings by Simulated Use

“…Todaro (2012) evaluated the effect of indirect steaming on the resistance to footprints of Quercus cerris L. wood for applications as parquet, and good elastic restoration was observed for untreated wood specimens, whereas for treated wood the resistance to footprints was higher in the radial than tangential direction. Sepliarsky et al (2018) analyzed Eucalyptus globulus and Quercus robur (oak) with different bases (HDF, solid and plywood pine) using the falling ball impact test. Their results are independent of the species used (Eucalyptus or oak) as a noble layer, however, they depend on the type of element used a base.…”
