Description
Technical field
The utility model relates to architectural engineering, in particular to a kind of rectangular steel pipe column-H-shaped steel beam is bolted semi-rigid entirely
Node.
Background technique
It since 2016, has put into effect, proposes positive about steel building industrialization and assembled architecture policy intensity
Green building and building materials are promoted, steel construction and assembled architecture are greatly developed.Assembling type steel structure system refers to according to unified, mark
Then quasi- building subassembly specification production house unit or component are transported to construction site assembly in place and the building of generation.It is special
Point is construction quality is light, energy conservation and environmental protection, speed of application is fast, industrialization degree is high etc., can solve China's building industrialization level it is low,
The problems such as house building labor productivity is low and conventional house product quality is low adapt to the development of China's building trade.
The application of rectangle steel tubing string gradually increases in current assembled steel frame, and compared to hot rolled H-shaped, rectangle steel tubing string is not obvious
Weak axis and have biggish torsional rigidity, its bearing capacity can be given full play in frame system, is composite steel Frame Design
In important column section type.But since rectangle steel tubing string itself is silent section, can not be mentioned for the construction of high-strength bolt connection
For space, it is difficult as H profile steel column to carry out assembled connection with conventional high-strength bolt.The interconnection technique of beam column is assembled steel
Most crucial technology, connecting structure and joint behavior play the performance of whole system highly important in frame structure system
Control action.Domestic and foreign scholars study the bolted end-plate connection between steel core concrete column and I-beam, but due to
Concrete has apparent restriction effect to the deformation of steel pipe walls, so relevant research conclusion is difficult to be generalized to box column and work shape
In the connecting node of beam.
Node according to the difference of rigidity property, be divided into just connect, hinged and varied rigid link, Semi-rigid Connection Steel Frame is because of section
Point has stronger deformability and energy dissipation capacity, is able to extend the natural vibration period of structure, can be consumed by controlling beam-ends plastic hinge
Seismic energy is dissipated, prevents from causing collapsing for structure because connecting node is destroyed, to substantially reduce earthquake, is conducive to antidetonation.Mesh
The main Types of preceding existing steel construction rectangular steel pipe column-H-shaped steel beam structures with semi-rigid joints are as follows: punching bolted end-plate connection, Liang Yi
Edge is connect by connector with post jamb and post jamb aperture repair welding type of attachment, all deposits although varied rigid link is various informative
In a degree of defect: punching bolted end-plate connection needs the length of special perforation column section to strength bolt is drawn high, and processes
And construction precision requirement is very high, construction efficiency reduces, and when using not contour special-shaped node, the through end plate connection of bolt is not
It is applicable in again；The flange of beam of connector formula node uses high-strength bolt, although improving the ductility and anti-seismic performance of node, reduces
Site welding amount is conducive to in-site installation construction, but due to not having internal partition power transmission in steel pipe, it is easy to appear columns for steel pipe column
Wall local buckling.Post jamb aperture repair welding connection need to usually open up temporary construction hole or truncation in steel pipe walls, pass through the construction
Nut is installed in hole on the inside of steel pipe, then by the scene repair welding of temporary construction hole, not only construction efficiency is low for this method, but also temporarily applies
Work hole destroys the globality of raw steel pipe, and live repair welding introduces welding residual stress, reduces its bearing capacity.
Bean column node is an element of frame structure, and the stress and safety for total have great shadow
It rings.Once connection destroys, structural elements can not just play a role, and construction is directly related to the safety of structure whether reasonable
Reliability.The construction method of bean column node directly affects the speed of application of engineering and the assembling degree of structure, therefore beam
Column border node should mostly use as far as possible convenient for the bolt connection of operation and the arrangement of bolt should possibly be easy to the fastening of worker scene.
Therefore, need to provide that a kind of construction is convenient, can effectively improve rectangle steel tubing string-H profile steel bearing capacity and comprehensive in engineering
Full bolt assembled connecting node at low cost is closed, the frame structure of H profile steel beam and rectangle steel tubing string composition can be greatly improved
Stress performance and globality.
Utility model content
