Description
Стыки раст нутых э„1ементов сборных предварительно-напр женных железобетонных конструкций с применением поперечных болтовнагелей и боковых металлических нак тадок, надеваемых на болты, известны. Недостаток таких стыкои заключаетс в том, что усили ог арматурных пучков раст нутых .leментов передаютс на болты-нагели неиосредственно через бетон, вызыва местное его см тие и разрушение .The joints of stretched e-elements of precast pre-stressed reinforced concrete structures with the use of transverse bolts on the gels and side metal bands that are worn on the bolts are known. The disadvantage of such joints is that the reinforcement beams of the stretched elements are transmitted to the bolts directly through the concrete, causing local collapse and destruction.
Особенностью описываемого стыка вл етс применение металлической сварной коробки, котора расположена на конце стыкуемого сборного железобетонного элемента м. составл одно целое с ним, служит дл прин ти усилий от анкерпых колодок арматурных пучков и передачи этих усилий болтамнагел м , вставленным в отверсти продольных листов (ребер коробки. Така конструкци исключает непосредствеиную передачу на усилий от болтов-нагелей ir позвол ет за счет уменьшени числа бa тoБ-нaгeлeй сделать стыковое соединение более компакт: ым иA special feature of the described joint is the use of a metal welded box, which is located at the end of the abutting precast concrete element and is integral with it, serves to receive forces from the anchor blocks of reinforcing beams and transfer these efforts to the bolts inserted into the holes of the longitudinal sheets This design eliminates the direct transmission of force from the bolts of the ir bolts, and, by reducing the number of battles, makes the butt joint more compact:
