Problems solved by technology

The existing prefabricated RC structure can basically guarantee no collapse under low-intensity earthquakes, mainly through the energy dissipation of the beam-hinge mechanism, but under high-intensity earthquakes, beam-column joints will occur Severe and irreversible damage makes it impossible to quickly repair and restore the function of the structure after the earthquake

Abstract

The invention discloses a fabricated RC structure beam-column connection joint convenient to maintain rapidly after an earthquake, and relates to fabricated RC structure connection joints. A column joint pre-buried steel piece is provided with a first connecting bulge, a beam joint pre-buried steel piece is provided with a second connecting bulge, a column end positioning steel plate is installed at the outer end of the first connecting bulge in a matched and buckling mode and fixedly connected through a plurality of pulling-resistant bolts, and a beam end positioning steel plate is installed at the outer end of the second connecting bulge in a matched and buckling mode and fixedly connected through a plurality of pulling-resistant bolts; and a column end lug plate is fixed to the column end positioning steel plate, a beam end lug plate is fixed to the beam end positioning steel plate, the column end lug plate is hinged to the beam end lug plate, one end of each buckling-proof dissipative member is detachably and fixedly connected with the column end positioning steel plate and the first connecting bulge, and the other end of each buckling-proof dissipative member is detachably and fixedly connected with the beam end positioning steel plate and the second connecting bulge. According to the fabricated RC structure beam-column connection joint convenient to maintain rapidly after the earthquake, a good energy-dissipating capacity is achieved, the probability of the situation that a structure is seriously injured is reduced when the earthquake intensity is relatively low, and replacing and maintaining can be conducted rapidly when the earthquake intensity is relatively high.

Description

technical field [0001] The invention relates to an assembled RC structure connection node, in particular to an assembled RC structure beam-column connection node which is convenient for rapid repair after an earthquake. Background technique [0002] In the past two decades, the rapid development of my country's construction industry has played an important role in stimulating the overall economy of our country. At present, my country's buildings generally adopt RC structures, that is, reinforced concrete structures. The traditional RC structure needs to follow the construction progress on site to carry out steel bar binding, concrete pouring, etc., and finally form an overall structure. On the one hand, the construction efficiency is low, and it is difficult to shorten the construction period. On the other hand, materials cannot be reused, which will generate a lot of construction waste. With the innovation and progress of construction technology, the emergence of prefabric...
