Description

Известно соединение между собой сборных железобетонных конструкций путем сварки заделанных в торцах стыкуемых конструкций закладных деталей в форме фасонных пластин, снабженных отверсти ми, через которые пропущены арматурные стержни, скрепленные гайками. В определенных услови х, в частности, при соединении раст нутых элементов предварительно напр женных железобетонных ферм, армированных стержневой арматурой из стали марки ЗОХГ2С, нат гиваемой на упоры стендов или форм, применение известных способов стыковани  оказываетс  нецелесообразным.It is known to interconnect precast reinforced concrete structures by welding embedded parts embedded in the ends of joined structures in the form of shaped plates equipped with openings through which reinforcing rods fastened with nuts are passed. Under certain conditions, in particular, when joining stretched elements of prestressed reinforced concrete trusses reinforced with bar reinforcement made from steel grade ZOHG2S, stretched to stand supports or forms, the use of known joining methods is impractical.

В этих услови х применение предложенной конструкции стыка позвол ет осуществить надежное соединение железобетонных элементов в конструкцию.Under these conditions, the application of the proposed joint design allows a reliable connection of reinforced concrete elements into the structure.

Отличительной особенностью предложенного стыка  вл етс  применение анкерных щайб, приваренных к арматурным стержн м у стыкуемой части элементов и передающих давление бетона на поперечные диафрагмы стальной анкерной коробки торца элемента, а через них на привариваемые соединительные накладки- Стык при этом осуп1ествл етс  без непосредственного соединени  стержней арматуры. Дл  увеличени  сцеплени  арматуры с бетоном внутри стальной коробки на стержни надеваютс  спирали из м гкой проволоки.A distinctive feature of the proposed joint is the use of anchor washers welded to the reinforcing bars at the joined part of the elements and transferring the pressure of concrete to the transverse diaphragms of the steel anchor box of the element face, and through them to the welded connecting plates, without any direct connection of reinforcement rods. . Soft wire spirals are worn on the rods to increase reinforcement adhesion to concrete inside the steel box.

На фиг. 1 изображен предложенный стык, примененный при соединении нижних по сов предварительно напр женных железобетонных полуферм , армированных стержневой арматурой, напр женной электротермическим способом; на фиг. 2 - то же, в разрезе по А-А.FIG. 1 depicts the proposed joint, applied when joining the lower part of pre-stressed reinforced concrete semi-ferries reinforced with rod reinforcement, strained by electrothermal method; in fig. 2 - the same, in a section on A-A.

Предложенный стык включает стальные анкерные коробки /, имеющие поперечные диафрагмы 2 и заделанные в торцовую часть стыкуемого элемента 3- В диафрагмах 2 имеютс  поперечные прорези 4 дл  свободной заводки в них напр гаемых стержней 5. На стержни 5 привариваютс  анкерные шайбы 6 и надеваютс  спира.чи 7. В анкерную коThe proposed joint includes steel anchor boxes / having transverse diaphragms 2 and embedded in the front part of the abutting element 3. In diaphragms 2 there are transverse slits 4 for free winding of tensioned rods 5. The rods 5 are welded by anchor washers 6 and put on spiral screws. 7. In anchor kit
