Двухместная полимерная форма для изготовления контрольных образцов бетона с возможностью ультразвукового исследования

Полезная модель относится к технике испытания материалов и может быть использована для изготовления контрольных образцов бетона. Заявленная форма состоит из поддона, стенок и съемной перегородки, выполненных из прозрачного пластика, в стенки формы встроены ультразвуковые преобразователи, а крепежные элементы выполнены в виде поворотных крючковых элементов Технический результат - повышение качества получаемых образцов, обеспечение возможности динамического наблюдения за процессом набора прочности образцами, а также снижение времени чистки и подготовки форм. Прозрачность стенок дает возможность наблюдения за качеством наполнения формы и процессом образования структуры образца, а ультразвуковые преобразователи, непосредственно прилегающие к бетонной смеси, позволяют динамически оценивать параметры набора прочности образцов бетона ультразвуковым методом. Применение полимерных компонентов формы за счет пониженной адгезии их к бетону позволяет упростить (и в некоторых случаях исключить) операцию смазки формы и снизить время последующей чистки, также рабочая поверхность ультразвуковых преобразователей может быть очищена методом кавитационной очистки ультразвуком в наполненной водой форме.

Molds and processes that permit high-speed, mass production of retaining wall blocks having patterned or other processed front faces, as well as retaining wall blocks formed by such processes. The invention permits the front face of the block to be impressed with a pattern or otherwise directly processed, to allow the formation of pre-determined block front faces, while at the same time facilitating high-speed, high-volume production of blocks. A mirror image of the desired pattern can be created on a stripper shoe by selecting a desired three-dimensional surface from a naturally occurring or man made object and digitally scanning the selected three-dimensional pattern to create scanned data. The scanned data can then be used to machine a face of the stripper shoe that is the mirror image of the selected pattern. 1.
