Embodiment Construction

[0027] Example: such as Figure 1-6 As shown, a prefabricated reinforced concrete frame beam-column joint connected by transverse bolts includes a hidden corbel 2 set on the beam of the prefabricated column 1. The cross section of the dark corbel 2 is rectangular or trapezoidal, and the upper Bolt holes 9 for concealed corbels are reserved in the horizontal direction; notch grooves 6 matching with concealed corbels 2 are provided on the front / rear sides of the joints at the ends of the prefabricated beams 3, and the notches 6 start from the vertical axis of the prefabricated beams 3 Dig a gap to one side, the gap has the same cross-sectional shape as the hidden corbel 2, and the size of the gap is slightly larger than the hidden corbel 2, so as to facilitate the embedding of the two, reserve prefabricated beam bolts at the corresponding position at the bottom of the notch groove 6 along the transverse direction Holes 10; the width of the concealed corbel 2 along the transverse...

Abstract

The invention relates to an assembled reinforced-concrete framework beam-column joint adopting transverse bolt connection. The joint comprises a hidden corbel arranged on a beam of a precast column, wherein hidden corbel bolt holes are transversely reserved in the hidden corbel; a notched groove matched with the hidden corbel is formed in the front / rear side face of an end-part connection part of a precast beam and is formed in a manner that the precast beam is notched towards one side of the precast beam from the vertical axis of the precast beam, the notched groove and the hidden corbel are the same in cross-section shape, and precast beam bolt holes are transversely reserved in corresponding positions of the bottom of the notched groove; and the transverse width of the hidden corbel is half that of the precast beam, the hidden corbel is embedded in the notched groove of the precast beam along the transverse direction, bolt cushion plates are arranged at the front and rear sides of an assembly which is formed after the hidden corbel is embedded in the notched groove of the precast beam, and bolts transversely penetrate through the bolt cushion plates, the hidden corbel bolt holes and the precast beam bolt holes so as to carry out fixing. A corresponding construction method comprises the steps of precasting, mounting and filling mortar in gaps. The joint and the corresponding construction method have the advantages that the internal force transmission between the precast beam and the precast column is clear, the joint is reliable in connection, the construction operation is simple, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to an assembled reinforced concrete frame beam-column node connected by transverse bolts and a construction method. Background technique [0002] The prefabricated reinforced concrete frame structure can improve the level of mechanized construction, speed up the construction progress, reduce labor intensity, realize industrialized production of buildings, and help protect the environment. This structural system has been widely used in developed countries and has become the main form of new buildings in some countries. The connection method is the core issue of the prefabricated reinforced concrete structure, and it is also the weak link of the structure. Only when the joint parts of the prefabricated components are reliably connected can the safety and reliability of the structure be guaranteed. [0003] The connection reliability of the existing prefabricated reinforced concrete frame joints in my country is poor, and it is diff...
