Embodiment Construction
[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0030] Specific embodiment 1 of the prefabricated beam-column connection node of the present invention, as Figure 1-Figure 6 As shown, the prefabricated beam-column connection node includes a concrete column 1, a concrete beam 2, and a metal damper 3 connecting the side of the concrete column 1 and the end face of the concrete beam 2. The concrete column 1 is provided with a column extending along the length of the column Longitudinal bars 10, where the length direction of the column refers to the vertical direction, and the concrete beam 2 is provided with beam longitudinal bars 20 extending along the length direction of the beam body, where the length direction of the b...

The invention provides a prefabricated beam-column connecting joint and a construction method thereof. The prefabricated beam-column connecting joint comprises a concrete column and a concrete beam, acolumn longitudinal bar extending in the length direction of a column body is arranged in the concrete column, and a beam longitudinal bar extending in the length direction of a beam body is arrangedin the concrete beam. The prefabricated beam-column connecting joint further comprises a metal damper connected between the concrete column and the concrete beam. The concrete column comprises an anchoring part pre-buried in the column body. The concrete beam comprises a pre-buried section connected with the beam longitudinal bar. The metal damper is fixedly connected with the pre-buried section.The metal damper comprises a connecting plate. The connecting plate and the anchoring part are detachably connected through a column thread connecting part. compared with a joint connecting mode in the prior art, the metal damper can achieve the effects of energy absorption and shock absorption, other steps are omitted while the basically same effect is achieved, the whole installation operationis simple and convenient, and rapid construction is facilitated.
Description
technical field [0001] The invention relates to the technical field of building structures, in particular to a prefabricated beam-column connection node and a construction method thereof. Background technique [0002] At present, in building construction, the method of pouring concrete on-site in the woven and formed steel skeleton is generally adopted. While the beam-column connection nodes of cast-in-place concrete have high strength and earthquake resistance, there are also problems such as large wet work load, long forming time, Serious environmental pollution and other issues. However, if only the prefabricated concrete columns and concrete beams are simply connected, it is obviously impossible to meet the strength and other performance requirements of the building structure. [0003] For example, the Chinese invention patent application with the application publication number CN108842912A and the application publication date of 2018.11.20 discloses a frictional energy...
