Конструкции полов с использованием Ñ€Ð°Ð·Ð»Ð¸Ñ‡Ð½Ñ‹Ñ Ð²Ð¸Ð´Ð¾Ð² фибры

Abstract

Данная работа посвящена исследованию и разработке конструкции промышленных полов из фибробетона и получению наиболее выгодной конструкции пола. Задачи, которые решались в ходе исследования: 1. Исследование физико-механических свойств и подбор состава фибробетона для применения в конструкции полов (проведение испытаний бетонов, армированных различными видами фибры). 2. Сравнительный анализ результатов испытаний и выбор оптимального варианта. 3. Проведение расчетов несущего слоя полов под действием сложных нагрузок. 4. Экономическое обоснование варианта конструкции. Экспериментальные исследования по испытанию мелкозернистых бетонов и бетонов с крупным заполнителем проводились в лабораториях инженерно-строительного института СПбПУ в соответствии с апробированными методиками с использованием сертифицированного оборудования. В ходе испытаний определялись такие физико-механические характеристик как прочность на сжатие и изгиб мелкозернистых фибробетонов и бетонов с крупным заполнителем. В результате были проанализированы конструкции полов на основе фибробетона разного состава, были проведены расчеты несущего слоя промышленных полов. Разработаны эффективные конструкции промышленных полов.

The given work is devoted to the research and development of the design of industrial floors made of fiber-reinforced concrete and obtaining the most advantageous floor design. The research set the following goals: 1. Study of physical and mechanical properties of fiber-reinforced concrete and selection of the composition of fiber-reinforced concrete for use in floor constructions. 2. Comparative analysis of test results and selection of the best option. 3. Carrying out calculations of the bearing layer of floors under the action of complex loads. 4. Economic justification of the design option. Experimental studies to test fine-grained concrete and concrete using a full aggregate carried out in the laboratories of the SPbPU Engineering and Construction Institute in accordance with approved methods using certified equipment. During the tests, such physical and mechanical characteristics as compressive strength and bending of fine-grained fiber-reinforced concrete and full-filled concrete, as well as electrical resistivity of samples of fine-grained concrete, were determined. As a result, floor structures based on fiber-reinforced concrete of various compositions were analyzed, calculations were made for the bearing layer of industrial floors. Efficient designs of industrial floors have been developed.
