Description
Изобретение касаетс способа замера линейных деформаций гор чих поверхностей -конструкций из жароупорного бетона с помощью кварцевых трубок, соединенных при помощи т г с измерительными приборами , установленными на холодной наружной поверхности исследуемой конструкции.The invention relates to a method for measuring linear deformations of hot surfaces of heat-resistant concrete structures using quartz tubes connected by means of tg with measuring instruments installed on the cold outer surface of the structure under study.
Недостатком известных уст -1ойств дл осуществлени этого способа вл етс то, что наличие соединительных т г вызывает необходимость введени температ}рных поправок в показани измерительных приборов , что усложн ет процесс и снижает точность замера деформаций.A disadvantage of the known methods for implementing this method is that the presence of connecting rods necessitates the introduction of temperature corrections to the readings of the measuring instruments, which complicates the process and reduces the accuracy of the measurement of deformations.
В описываемом устройстве применение дл замера деформаций в конструкци х Из жароупорного бетона пары кварцевых трубок или стержней разной длины, имеющих контакт с исследуемой поверхностью на измер емой базе, дает большую точность замера деформаций и удобство в работе, так как не требуетс вводить в показани приборов температурных поправок.In the described device, the use for measuring strains in heat-resistant concrete, pairs of quartz tubes or rods of different lengths that come into contact with the surface under test on the base to be measured, provides greater accuracy in measuring strains and convenience in operation, since it is not necessary to enter amendments.
На чертеже изображено предложенное устройство. Кварцевые трубки / и 2, имеюпше различную длину, креп тс к исследуемой конструкции попарно с помощью ножевых шарниров, дл чего в стенкн исследуемой конструкции вмазываютс анкера 3 и 4 из жаропрочной стали. Анкера должны быть достаточно жесткими, чтобы они не могли деформироватьс силой нат жени кварцевых трубок. Разница в длине кварцевых трубок составл ет базу замера 5.The drawing shows the proposed device. The quartz tubes / and 2, having different lengths, are fastened to the structure under study in pairs using knife joints, for which anchors 3 and 4 are made of heat-resistant steel in the walls of the structure under study. Anchors must be sufficiently rigid so that they cannot be deformed by the tension force of quartz tubes. The difference in the length of the quartz tubes is the measurement base 5.
Т ги 5 и 7 выполн ютс из жаропрочной стали или нихрома и соедин ютс также шарнирно с двум совмещенными измерительными приборами 8 VI 9, «оторые наход тс вне зоны нагрева.The plugs 5 and 7 are made of heat-resistant steel or nichrome and are also connected pivotally with two combined measuring devices 8 VI 9, which are outside the heating zone.
В св зи с таким устройством разность показаний измерительных приборов на любом этапе нагрева или загружени дает приращение базы, то есть того участка конструкции, по концам которого креп тс кварцевые трубки.In connection with such a device, the difference in the readings of the measuring instruments at any stage of heating or loading gives an increment to the base, i.e. that portion of the structure at the ends of which the quartz tubes are attached.
