Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0041] like figure 1As shown, a connection structure of prefabricated recycled block concrete beams, including corbels 1 prefabricated simultaneously with columns, prefabricated beams 2 with notches at the ends, positioning plates with holes 4, vertical bars 9, stirrups 11, common Longitudinal bars 8 , bent longitudinal bars 3 , steel sleeves with internal threads 5 , steel bar bars with external threads 6 , shear steel 10 and axial tunnels 7 .

[0042] The size of the complete section of the corbel 1 prefabricated at the same time as the column is 350 mm × 600 mm, the size of the complete section of the prefabricated beam 2 with notches at the end is 350 mm × 600 mm, and the diameter of the vertical reinforcement 9 and the stirrup 11 is 10 mm 1. The diameters of the be...

Abstract

The invention discloses a connecting structure for a prefabricated regenerated block concrete beam. The connecting structure comprises a bracket which is simultaneously prefabricated with a column, a prefabricated beam with a notch in an end part, a positioning plate with a hole, an erecting rib, a hoop rib, a common longitudinal rib, a bent longitudinal rib, a steel sleeve with an internal thread, a rebar rod with an external thread, an anti-shearing steel and an axial pore channel. The invention also discloses a construction method for the connecting structure for the prefabricated regenerated block concrete beam. According to the invention, the site pouring volume is less and the construction speed is high and the bent longitudinal rib is adopted, so that the thickness of a concrete protecting layer of the axial pore channel filled with the structure glue is obviously increased, the degradation of the fire disaster for the structure glue is effectively relieved, the effective connection in a connection area between the bracket which is simultaneously prefabricated with the column and the prefabricated beam with the notch in the end part is guaranteed, the beam has excellent water resistance, the connecting area is yielded and forms a plastic hinge in advance under an earthquake effect and the realization of the 'strong-column weak-beam' anti-seismic thought is guaranteed.

Description

technical field [0001] The invention relates to the technical field of waste concrete recycling, in particular to a connection structure of prefabricated recycled block concrete beams and a construction method thereof. Background technique [0002] With the worsening of environmental problems, the recycling of waste concrete has attracted widespread attention at home and abroad. Compared with the traditional recycled coarse aggregate and recycled fine aggregate, the use of larger-scale waste concrete blocks not only has the advantages of high crushing efficiency and low crushing energy consumption, but also can significantly reduce the subsequent cement consumption, and the environmental protection and energy saving benefits are obvious . At the same time, the country is focusing on the Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta urban agglomerations and other cities with a permanent population of more than 3 million, vigorously developing prefabricated bu...
