Description
Technical Field
The invention belongs to the technical field of building structures, and particularly relates to a RCS (reinforced concrete) assembly of a high-strength spiral steel fiber concrete column and a honeycomb steel beam and a construction method thereof.
Background
The RCS composite structure is a novel structural form and is a frame structure consisting of reinforced concrete columns and steel beams. The RCS combined structure system has the advantages of a traditional steel structure and an RC structure. The lateral rigidity and the strength of the RC column are superior to those of a steel column; and RC columns are more economical than steel columns. The construction speed of the steel beam is faster than that of the concrete beam. Compared with a common reinforced concrete structure, the RCS hybrid frame structure has the advantages of lighter self weight, larger available space of a building, higher construction speed and the like; compared with steel structure, the steel structure has lower cost and more excellent performances in rigidity, fire resistance, durability and the like. Based on the above advantages, the RCS composite structure has gained attention from engineers in various countries around the world. Since concrete is a brittle material, when it deforms beyond its ultimate compressive strain, the concrete will collapse and the load bearing capacity will decrease. One of the main failure modes of the RCS node area is concrete bearing failure.
Disclosure of Invention
The invention provides a RCS assembly of a spiral steel fiber concrete column and a honeycomb steel beam and a construction method thereof, wherein under the action of a large load on the assembly, high-strength concrete is subjected to multiple constraints of ring-type welding stirrups, steel plate hoops and spiral steel fibers, so that the assembly is ensured to have high bearing capacity under the condition of large deformation; moreover, good ductility also improves the seismic performance of the assembly.
In order to solve the technical problems, the technical scheme of the invention is as follows:
a spiral steel fiber concrete column and honeycomb steel beam RCS assembly comprising: steel beams, spiral steel fiber concrete columns, ring type welding stirrups, bolt rods and steel plate hoops;
the two steel beams are arranged at intervals along the same straight line; one side of the two steel beams opposite to each other is provided with a steel beam end plate; a steel plate hoop is arranged between the two steel beam end plates in a propping manner; bolt holes are respectively formed in two side faces of the steel plate hoop along the extension direction of the steel beam, and a bolt rod is connected between the two side faces through the bolt holes;
the spiral steel fiber concrete column is vertically arranged with the steel beam and penetrates through the steel plate hoop; the bolt rod of the steel plate hoop penetrates through the spiral steel fiber concrete column along the width direction of the spiral steel fiber concrete column;
the ring type welding stirrups are arranged at intervals along the height direction of the spiral steel fiber concrete column.
In a preferred embodiment: the bolt holes are arranged in two rows, and bolt rods corresponding to the bolt holes penetrate through the spiral steel fiber concrete column along the width direction of the spiral steel fiber concrete column.
In a preferred embodiment: the steel beam is Q345 steel, and the section of the steel beam is I-shaped.
In a preferred embodiment: the spiral steel fiber concrete column samples concrete with the grade of C50 and above.
The invention also provides a construction method of the RCS assembly of the spiral steel fiber concrete column and the honeycomb steel beam, which comprises the following steps:
1) processing a steel beam in a factory, and welding a stirrup, a steel plate hoop and a high-strength bolt in a ring mode; one end of the steel beam along the length direction is provided with a steel beam end plate;
2) binding steel bars on the set columns, and welding ring-type welding stirrups;
3) arranging the steel plate hoop on a node area of a set pillar, and inserting a bolt rod through a bolt hole reserved on the steel plate hoop to fix the steel plate hoop and the pillar;
4) blending concrete, adding spiral steel fibers after the concrete is uniformly stirred, and stirring the mixture; and pouring the prepared steel fiber concrete, and connecting the steel beam end plates through the reserved bolt rods after the concrete is hardened.
In a preferred embodiment: the bolt holes are arranged in two rows, and bolt rods corresponding to the bolt holes penetrate through the spiral steel fiber concrete column along the width direction of the spiral steel fiber concrete column.
In a preferred embodiment: the steel beam is Q345 steel, and the section of the steel beam is I-shaped.
In a preferred embodiment: the spiral steel fiber concrete column samples concrete with the grade of C50 and above.
Compared with the prior art, the invention has the following advantages and outstanding effects:
the invention provides a spiral steel fiber concrete column and honeycomb steel beam RCS assembly which is used for improving the concrete ultimate compressive strain, further improving the ductility of a ring-type welded stirrup high-strength concrete column and honeycomb steel beam RCS assembly and enhancing the pressure-bearing capacity of an RCS node area. The steel fibers are distributed in the concrete in a disorderly manner, so that the expansion of micro cracks in the concrete is hindered, the occurrence and the development of macro cracks are retarded, and the ductility of the combined column is further improved. In addition, the ductility of the combined column is improved, and the energy consumption capacity of the combined column during earthquake is improved, so that the earthquake resistance of the RCS combined piece of the ring-type welded stirrup high-strength spiral steel fiber concrete column and the honeycomb steel beam is enhanced. The ring-type welding stirrup has the following advantages: (1) the binding force provided by the ring-type welding stirrup on concrete is far greater than that of a common hook stirrup; (2) the common hook stirrup at the beam column node is difficult to adjust, the situations of less placing and no placing of the node stirrup are easily caused, the shock resistance of the frame node is greatly reduced, and the situations do not exist in the ring-type welding stirrup. (3) By adopting the ring-type welded stirrups, the blanking is easy during concrete pouring, and the situations of holes, exposed reinforcements and the like are not easy to cause. In conclusion, the RCS assembly of the ring-type welded stirrup high-strength spiral steel fiber concrete column and the honeycomb steel beam greatly promotes the development and the practical engineering application of the RCS combined structure.
