Technical field
The present invention relates to assembled beam-column interconnection technique fields, consume energy more particularly to a kind of assembled beam-column lead extrusion pressing type Node.
Background technique
Assembly concrete building refers to based on the concrete prefabricated element with the factorial production, passes through site-assembled side The concrete structure class building construction of formula design-build.The assembly method of component pours overlapping layer concrete, steel after generally having scene Sleeve grouting connection, welding, mechanical connection and reserving hole overlap joint can be used in pouring concrete connection etc. after muscle anchoring, reinforcing bar connection The ways such as connection.
With the quickening of China " building industrialization, housing industrialization " process and the continuous reduction of China's " demographic dividend " With the appearance of building trade recruitment famine, the trend of housing industry industrialization is increasingly obvious.The application weight of prefabricated concrete structure Newly become current research hot spot, all parts of the country continue to bring out out new technology, the new model of residential housing prefabricated concrete structure. Precast reinforced concrete structure is one of the important directions of China's building structure development, it is conducive to China's building industrialization Development, raising production efficiency is energy saving, develops Green environmental-protection building, and is conducive to improve and guarantee construction engineering quality. The dry type connection of assembled beam-column can reduce cast-in-place concrete operation, be more suitable for the requirement of building industrialization, therefore answer With extensive, but dry type connection reliability is poor.
Summary of the 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.
To achieve the above object, the present invention provides following schemes:
The present invention provides a kind of assembled beam-column lead extrusion pressing type energy dissipation node, including precast concrete column and precast concrete Beam;It is preset with steel plate on the outside of the precast concrete column, lead is provided on the steel plate, the precast concrete column passes through institute Steel plate is stated to be fixedly connected with the precast concrete beam.
Optionally, the lead is rectangular block shape structure, and there are two the lead, the lead positions for setting on the steel plate Between the precast concrete beam and the steel plate.
Optionally, the lead is rectangular parallelepiped structure, is provided with the lead on the steel plate, the lead is located at Between the precast concrete beam and the steel plate.
Optionally, the upper and lower ends of the steel plate are respectively arranged with a steel side plate, and the precast concrete beam is close to institute The one end for stating precast concrete column is located between two steel side plates, and is respectively fixedly connected with the steel side plate.
Optionally, the steel plate and the precast concrete beam are fixed by riveting.
The present invention achieves following technical effect compared with the existing technology:
Assembled beam-column lead extrusion pressing type energy dissipation node provided by the invention improves assembly using lead extrusion pressing type energy dissipation node The reliability of the dry type connection of formula beam column greatly reduces the destruction in node area so that node has certain energy dissipation capacity;Pass through Prefabricated beam-ends, which squeezes lead, realizes energy dissipation node, and consume energy clear principle, and joint form may be implemented simply by the design of lead Different energy consumption demands.
Detailed description of the invention
It in order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below will be to institute in embodiment Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the invention Example, for those of ordinary skill in the art, without any creative labor, can also be according to these attached drawings Obtain other attached drawings.
Fig. 1 is one structural schematic diagram of assembled beam-column lead extrusion pressing type energy dissipation node embodiment of the present invention;
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
The present embodiment is that structure made on the basis of example 1 changes and further improves, in embodiment On the basis of one, as shown in Fig. 2, being changed to lead 4 for rectangular parallelepiped structure, it is provided with a lead 4 on steel plate 3, to process More convenient, more evenly, lead 4 is between precast concrete beam 2 and steel plate 3 for stress.The upper and lower ends of steel plate 3 are respectively arranged with One steel side plate 5, precast concrete beam 2 are located between two steel side plates 5 close to one end of precast concrete column 1, and prefabricated mixed Solidifying soil beam 2 is respectively fixedly connected with steel side plate 5, further improves precast concrete beam 2 and 1 junction of precast concrete column Fastness, securely and reliably.
When earthquake or when having biggish wind, 2 end of precast concrete beam bends, and squeezes lead 4, lead be yield point very Low metal material is plastically deformed under the extruding at 2 end of precast concrete beam, dissipation seismic energy, using lead extrusion pressing type The reliability that energy dissipation node improves the dry type connection of assembled beam-column subtracts significantly so that node has certain energy dissipation capacity The destruction in minor node area.
Specific examples are applied in the present invention, and principle and implementation of the present invention are described, above embodiments Illustrate to be merely used to help understand method and its core concept of the invention;At the same time, for those skilled in the art, according to According to thought of the invention, there will be changes in the specific implementation manner and application range.In conclusion the content of the present specification It should not be construed as limiting the invention.
