Description

The connecting node and preparation method of a kind of H profile steel beam and rectangular steel-tube concrete column
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 launched rapidly, steel tube concrete Earth pillar structure is that fill concrete is constituted 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 is prevented from the too early flexing of steel pipe, the two synergy energy Enough give full play to that steel examining tensile behavior is high and the good advantage of core concrete Compressive Performance, thus with high capacity, plasticity and Good toughness, anti-seismic performance are good, remarkable in economical benefits and construction environmental protection many advantages, such as.
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 Have the advantages that 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 The features such as face flexible arrangement, simple structure, component are easy to standardization, fast speed of application, low cost, in executive information systems In have 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, and steel pipe column outside is not put more energy into Plate, facilitates curtain wall to install, it is adaptable to large-size frame post, and steel using amount has compared with outer shroud node and reduces 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 is transmitted mainly is undertaken by internal partition, the main core by steel duct of the pressure that steel beam flange is transmitted Concrete undertakes, and stress form is a kind of joint form for generally using rationally.
Because rectangular steel pipe is not so good as round steel pipe significantly to the effect of contraction of core concrete, and internal core concrete is subject to 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 Limitation long, the internal partition formula connecting node of existing middle part perforate so that core concrete pours difficult, inconvenience of vibrating, The density that is poured to core concrete and the constraint to core concrete are affected greatly, so as to influence rectangular steel pipe to mix The holistic resistant behavior of solidifying earth pillar.
The preparation method of existing internal partition formula rectangular steel-tube concrete column, internal partition generally uses " melting nozzle electroslag welding " Method is connected with rectangle steel tubing string, constructs complicated and relatively costly.
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 Packing and the low internal partition connecting node of integrated cost are built, H profile steel beam can be greatly improved and constituted with rectangular steel-tube concrete column Frame structure stress performance and globality.
The content of the invention
