(54) АГРЕГАТ ДЛЯ НАВЕСНОГО МОНТАЖА НЕРАЗРЕЗНЫХ ПРЕИМУЩЕСТВЕННО ПРЕДВАРИТЕЛЬНО НАПРЯЖЕННЫХ ЖЕЛЕЗОБЕТОННЫХ ПРОЛЕТНЫХ СТРОЕНИЙ МОСТОВ(54) UNIT FOR OUTDOOR INSTALLATION OF UNCURRENT PREFERREDLY PREDICTLY STRESSED REINFORCED CONVERSE BRIDGE STRUCTURES

Несуща ферма 1 треугольного поперечного сечени имеет нижний и верхний по са, по которым соответственно передвигаютс грузова тележка и рама поддерживающего приспособлени .The carrier truss 1 of a triangular cross section has a lower and an upper frame along which, respectively, the load carriage and the frame of the supporting device move.
Опорные стойки 2, 3, 4 вьщолнены телескопическими , передние стойки 2, кроме того, могут отклон тьс вперед и вьшолн ть роль аванбека при перемещении крана из пролета в пролет.The support pillars 2, 3, 4 are telescopic, the front pillars 2, in addition, can be deflected forward and play the role of an avanbec when moving the crane from one flight to another.
Платформы 7, 8 рамы поддерживающего приспособлени снабжены подвижной базой типа кареток 10 и И с автономным приводом. Верхн платформа 7 имеет домкрат 12 дл изменени положени рамы по высоте, а нижн платформа 8 пути передвижени 13 из съемных элементов. Нижн платформа 8 одним концом прикреплена посредством шарнирного соединени к одной из соединительных т г 9 и может опускатьс до вертикального положени при проходе агрегата через промежуточные опоры моста.The platforms 7, 8 of the frame of the supporting device are equipped with a movable base such as carriages 10 and And with an independent drive. The upper platform 7 has a jack 12 for changing the position of the frame in height, and the lower platform 8 of the traveling path 13 of the removable elements. The bottom platform 8 is at one end attached by a swivel to one of the connecting rods 9 and can be lowered to a vertical position when the machine passes through the intermediate supports of the bridge.
Агрегат работает следующим образом. Блоки 14 пролетного строени подвод т к агрегату по верху ранее собранного пролетного строени на трейлерах 15. Блоки 14 поднимают грузовой тележкой 5 и подают вперед к месту монтажа. По ходу подачи, после прохода средних опорных стоек, блок поворачивают вокруг вертикальной оси на 90 из транспортного положени в проектное.The unit works as follows. The blocks 14 of the superstructure lead to the unit along the top of the previously assembled superstructure on the trailers 15. The blocks 14 lift with a loading trolley 5 and are fed forward to the installation site. In the course of the supply, after passing through the middle support posts, the block is turned around a vertical axis by 90 from the transport position to the design one.
При длине монтируемых пролетов, близкой или равной длине фермы агрегата пролетное строение монтируют следующим образом. Первую половину пролета собирают без поддержки конца консоли агрегатом, причем агрегат вьщвигаетс в монтируемый пролет только на половину своей длины (до середины пролета). Устойчивость агрегата обеспечиваетс анкеровкой за предьщущий пролет с помощью поддерживающего приспособлени . По смонтированной консоли пролетного строени агре гат полностью вьщвигают вперед и устанавливают в пролете. Монтаж пролетного строени продолжают уже с поддержкой конца консоли рамой поддерживающего приспособлени агрегата.When the length of the spans being mounted is close to or equal to the length of the aggregate truss, the span structure is mounted as follows. The first half of the span is assembled without supporting the end of the console by the unit, and the unit is pushed into the span to be assembled only half its length (until the middle of the span). The stability of the unit is provided by anchoring the previous span by means of a support device. On the mounted console, the span of the aggregate is fully extended forward and installed in the span. The installation of the span is continued already with the support of the console end with the frame of the supporting device of the unit.
При длине монтируемых пролетов, равной половине и менее половины длины фермы агрегата, агрегат сразу устанавливают в монтируемый пролет , и монтаж первой половины пролета осуществл ют как без поддержки, так и с поддержкой конца консоли рамой поддерживающего приспособлени агрегата.With the length of the spans being mounted equal to half and less than half the length of the unit farm, the unit is immediately installed in the span to be mounted, and the installation of the first half of the span is carried out both without support and with the support of the end of the console with the frame of the supporting device of the unit.
При длине монтируемых пролетов, равной половине и менее половины длины фермы агрегата, агрегат сразу устанавливают в монтируемый пролет , и монтаж первой половины пролета осуществл ют как без поддержки, так и с поддержкой конца консоли агрегатом, причем в последнем случае производство работ упрощаетс и возрастает темп монтажа.With the length of the spans being mounted equal to half and less than half the length of the unit farm, the unit is immediately installed in the span to be mounted, and the installation of the first half span is carried out both without support and with support for the end of the console with the unit, and in the latter case the work mounting.
