Изобретение относитс  к области испытани  конструкций.This invention relates to the field of structural testing.

Известен способ статического испытани  перекрыти  эксплуатируемого здани , сооружени  и т. п. с несущими металлическими балками путем ступенчатой передачи нагрузки и замера деформаций. Дл  осуществлени  этого способа необходимо проводить демонтаж оборудовани , что  вл етс  трудоемкой операцией , значительно усложн ющей производство работ.There is a known method for static testing of the overlap of a building in operation, a structure, etc., with bearing metal beams by means of a stepwise transfer of the load and measurement of the deformations. To implement this method, it is necessary to disassemble the equipment, which is a time consuming operation that significantly complicates the work.

Цель изобретени  - исключение необходимости демонтажа оборудовани  и облегчение производства работ. Дл  этого по предлагаемому способу под испытываемым перекрытием монтируют инвентарные подмости, устанавливают домкраты, создают направленное вверх контролируемое давление, после достижени  расчетного давлени  снимают нагрузку ступен ми и замер ют деформации, по величине которых суд т о несущей способности перекрыти .The purpose of the invention is to eliminate the need to dismantle equipment and facilitate the production of works. To do this, according to the proposed method, inventory scaffolds are installed under the overlap to be tested, jacks are created, controlled pressure is directed upwards, after reaching the calculated pressure, the load is relieved by steps and the strains are measured according to the size of the bearing capacity of the overlap.

На чертеже схематично изображено испытываемое перекрытие, вид сбоку.The drawing schematically shows the tested overlap, side view.

Рабочий процесс статического испытани  перекрыти  эксплуатируемого здани , сооружени  и т. п. с несущими металлическими балками осуществл ют следующим образом.The workflow of static testing of the overlap of an operated building, structure, etc. with bearing metal beams is carried out as follows.

Под испытываемым перекрытием 1 с расположенным на нем действующим оборудованием 2 на подкладные брусь  3 устанавливают инвентарные подмости 4, монтируют домкраты 5, динамометры 6 и распределительные устройства 7, охватывающие испытываемое перекрытие 1. К колоннам 8 сооружени  на струбцинах 9 креп т рейки 10, на которых размещают деформометры //. В испытываемом перекрытии 1 ступен ми по 1/5-1/10 от расчетного давлени  домкратами 5 создают направленное вверх контролируемое давление и замер ют деформации. После достижени  расчетного давлени  и выдержки под давлением во времени (не менее 30 минут) снимают давление теми же ступен ми и вновь замер ют деформации, по величине которых суд т о несущей способности перекрыти . При необходимости процесс испытани  повтор ют .Under test overlap 1 with existing equipment 2 located on it, inventory racks 4 are installed on back rails 3, jacks 5, dynamometers 6 and distribution devices 7 are mounted, covering test overlap 1. To columns 8 structures on clamps 9 lath rails 10 on which place the deformometers //. In the test overlap, 1 steps of 1 / 5-1 / 10 of the design pressure by the jacks 5 create an upward controlled pressure and measure the deformations. After reaching the design pressure and holding it under pressure over time (at least 30 minutes), the pressure is relieved by the same steps and again the strains are measured, the magnitude of which determines the bearing capacity of the slab. If necessary, the testing process is repeated.

Предмет изобретени Subject invention

Способ статического испытани  перекрыти  эксплуатируемого здани , сооружени  и т. п. с несущими металлическими балками путем ступенчатой передачи нагрузки и замера деформаций , отличающийс  тем, что, с целью исключени  необходимости демонтажа оборудовани  и облегчени  производства работ, под испытываемым перекрытием монтируют инвентарные подмости, устанавливают домкраты , создают направленное вверх контролируемое давление, и после достижени  расчетного давлени  снимают нагрузку ступен ми и замер ют деформапии, по величине которых суд т о несущей способности перекрыти .A static test method for overlapping an operated building, structure, etc., with load-bearing metal beams by means of a stepwise transfer of the load and measurement of deformations, characterized in that, in order to eliminate the need to dismantle the equipment and facilitate work, the scaffolding is installed under the tested overlap, jacks are installed , an upward controlled pressure is created, and after reaching the design pressure, the load is relieved in steps and the strains are measured, judging on bearing capacity.
