Fig. 2 is two structural schematic diagram of assembled beam-column lead extrusion pressing type energy dissipation node embodiment of the present invention；
Wherein, 1 it is precast concrete column, 2 be precast concrete beam, 3 be steel plate, 4 be lead, 5 is steel side plate.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The object of the present invention is to provide a kind of assembled beam-column lead extrusion pressing type energy dissipation nodes, are deposited with solving the above-mentioned prior art
The problem of, improve assembled beam-column dry type connection reliability so that node have certain energy dissipation capacity, greatly reduce
The destruction in node area.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Embodiment one
The present invention provides a kind of assembled beam-column lead extrusion pressing type energy dissipation node, as shown in Figure 1, including precast concrete column 1
With precast concrete beam 2；It is preset with steel plate 3 on the outside of precast concrete column 1, lead 4, precast concrete column 1 are provided on steel plate 3
It is fixedly connected by steel plate 3 with precast concrete beam 2.Lead 4 is rectangular block shape structure, lead 4 there are two settings on steel plate 3,
Lead 4 is between precast concrete beam 2 and steel plate 3.Steel plate 3 and precast concrete beam 2 are fixed by riveting.
Embodiment two
