Abstract

1. Способ строительства сборных дорожных покрытий, включающий укладку предварительно напряженных прямоугольных или квадратных железобетонных плит на земляное, песчаное или другое основание, скрепление плит друг с другом в одном или двух взаимно перпендикулярных направлениях с помощью сквозной арматуры в каналах с последующим ее натяжением, заделку швов между плитами герметичным материалом, покрытие бетонного основания асфальтом или литым асфальтобетоном, отличающийся тем, что скрепление железобетонных плит осуществляют стягиванием в пакеты, содержащие от 5 до 20 плит, стальными канатами с последующим натяжением с усилием от 5 до 30 тс на каждый канат, при этом между торцами плит на канаты надевают упругие элементы, стальные канаты размещают в сквозных каналах, расположенных в средней части плит, а концы канатов после натяжения закрепляют анкерами в крепежных полостях крайних в пакетах плит с омоноличиванием полостей бетоном. ! 2. Конструкция сборного дорожного покрытия, включающая земляное, песчаное или другое основание, предварительно напряженные скрепленные друг с другом прямоугольные или квадратные плиты; швы, заполненные герметичным материалом, и мягкое верхнее покрытие бетонных плит из асфальта или литого асфальтобетона, отличающаяся тем, что стальные канаты расположены в сквозных каналах во внутреннем объеме плит на расстоянии 0,7-2,0 м друг от друга (по осям), длина стягивающих и напрягаемых стальных канатов выбрана в пределах от 15 до 60 м; омоноличенные бетоном крепежные полости для анкеров и концов стальных канатов изготовлены прямоугольными или квадратными с соотношением ширины к длине, выбранны�1. The method of construction of prefabricated pavements, including laying prestressed rectangular or square reinforced concrete slabs on an earthen, sand or other base, bonding the slabs to each other in one or two mutually perpendicular directions using through fittings in the channels with its subsequent tension, sealing joints between slabs with hermetic material, covering a concrete base with asphalt or cast asphalt, characterized in that the reinforced concrete slabs are fastened together by pulling together in packages containing from 5 to 20 plates, with steel ropes, followed by tension with a force of 5 to 30 ton-force per rope, while elastic elements are put on the ropes between the ends of the plates, steel ropes are placed in through channels located in the middle of the plates, and the ends of the ropes after tensioning are fixed with anchors in the fastening cavities of the extreme in packs of plates with monolithic cavities with concrete. ! 2. The design of the precast road surface, including earthen, sand or other base, pre-stressed rectangular or square plates bonded to each other; seams filled with airtight material, and a soft top coating of concrete slabs made of asphalt or cast asphalt, characterized in that the steel ropes are located in the through channels in the internal volume of the slabs at a distance of 0.7-2.0 m from each other (along the axes), the length of the tightening and prestressing steel ropes is selected in the range from 15 to 60 m; monolithic fastening cavities for anchors and ends of steel ropes are made rectangular or square with a ratio of width to length, selected�

Claims

1. The method of construction of prefabricated pavements, including laying prestressed rectangular or square reinforced concrete slabs on an earthen, sand or other base, bonding the slabs to each other in one or two mutually perpendicular directions using through fittings in the channels with its subsequent tension, sealing joints between slabs with hermetic material, covering a concrete base with asphalt or cast asphalt, characterized in that the reinforced concrete slabs are fastened together by pulling together in packages containing from 5 to 20 plates, with steel ropes, followed by tension with a force of 5 to 30 ton-force per rope, while elastic elements are put on the ropes between the ends of the plates, steel ropes are placed in through channels located in the middle of the plates, and the ends of the ropes after tensioning are fixed with anchors in the fastening cavities of the extreme in packs of plates with monolithic cavities with concrete.

2. The design of the precast road surface, including earthen, sand or other base, pre-stressed rectangular or square plates bonded to each other; seams filled with sealed material and a soft top coating of concrete slabs made of asphalt or cast asphalt, characterized in that the steel ropes are located in the through channels in the internal volume of the slabs at a distance of 0.7-2.0 m from each other (along the axes), the length of the tightening and prestressing steel ropes is selected in the range from 15 to 60 m; monolithic fastening cavities for anchors and ends of steel ropes are made rectangular or square with a ratio of width to length selected in the range from 1: 1 to 1: 4 of the thickness of the plates, until monolithic with concrete open upwards and bounded below by the lower surface of the through channels, the elastic elements are made preferably rubber in the form of cylinders or parallelepipeds with a cross-sectional area of 4 to 20 cross-sectional areas of the through channels and a length of 0.3 to 1.0 plate thickness, and the size of the joints between the pl Tammy selected from 15 to 40 mm.
