Description
Technical field
The invention belongs to building engineering field, and in particular to building structure technology, more particularly to H profile steel beam and rectangular steel pipe
The connecting node and preparation method of concrete column.
Background technology
With the development of building structure, the research and application of steel-concrete combined structure are deployed rapidly, steel tube concrete
Earth pillar structure is that fill concrete is formed in steel pipe, and the presence of steel pipe can constrain core concrete, prevent core coagulation
Soil premature rupture in loading process；The presence of core concrete can prevent the too early flexing of steel pipe, the two synergy energy
Enough give full play to the advantages of steel examining tensile behavior is high and core concrete Compressive Performance is good, thus with high capacity, plasticity and
Many advantages, such as good toughness, anti-seismic performance are good, remarkable in economical benefits and construction are environmentally friendly.
The characteristics such as the existing plastic deformation ability of rectangular steel-tube concrete column is strong, the good, excellent earthquake resistance of ductility, and more
There is the advantages of bending rigidity is big, node is easy to connect.The frame structure system that rectangular steel-tube concrete column is formed with girder steel, because flat
Face flexible arrangement, simple in construction, component are easy to the features such as standardization, speed of application fast, low cost, in executive information systems
In there is good application prospect, by the most attention in domestic and international project field.
In the frame structure system that rectangular steel-tube concrete column and girder steel are formed, H profile steel beam and concrete-filled rectangular steel tube
The frame system application that post is formed is universal.The connecting node of H profile steel beam and rectangular steel-tube concrete column, according to the cloth of connecting node
Put, be broadly divided into：Internal partition formula, outer shroud gusset-type joint and diaphragm-through type connecting node three major types.Wherein, internal partition formula section
Point is that the power transmission internal partition component of node is located inside rectangular steel pipe, and board size of putting more energy into is smaller, is not put more energy on the outside of steel pipe column
Plate, curtain wall is facilitated to install, suitable for large-size frame post, and steel using amount has compared with outer shroud node and reduced to a certain degree.H profile steel beam
Internal force passes to steel tube concrete frame puncheon by internal partition, and moment of flexure, the main Transfer of Shear of web are mainly transmitted in the upper and lower edge of a wing.
The pulling force effect that steel beam flange transmits mainly is undertaken by internal partition, and the pressure that steel beam flange transmits is mainly by the core of steel duct
Concrete undertakes, and stress form is reasonable, is a kind of joint form generally used.
Due to rectangular steel pipe to the effect of contraction of core concrete be not as notable as round steel pipe, and internal core concrete by
Constraint it is uneven, therefore rectangular steel-tube concrete column is higher to pouring core concrete quality requirement.And due to by tubing string side
Long limitation, the internal partition formula connecting node of existing middle part perforate so that core concrete pours difficult, inconvenience of vibrating,
The density poured to core concrete and the constraint to core concrete affect greatly, and are mixed so as to influence rectangular steel pipe
The holistic resistant behavior of solidifying earth pillar.
The preparation method of existing internal partition formula rectangular steel-tube concrete column, internal partition generally use " melting nozzle electroslag welding "
Method is connected with rectangle steel tubing string, and construction is complicated and cost is higher.
Therefore need to provide that a kind of construction is convenient, can effectively improve rectangle steel tubing string inner core concrete pours in engineering practice
Compactness and the low internal partition connecting node of integrated cost are built, H profile steel beam can be greatly improved and formed with rectangular steel-tube concrete column
Frame structure stress performance and globality.
