Description
Technical Field
The utility model belongs to the technical field of assembled building structures, and particularly relates to a beam-column structure.
Background
Compared with the traditional building, the fabricated building has less research on the earthquake resistance. At present, the focus of the research on the earthquake-resistant performance of the assembled building is on nodes.
The assembled building is formed by transferring a large amount of field operation work in a traditional building mode to a factory, processing and manufacturing building components and accessories in the factory, transporting to a building construction site, and assembling and installing the building on site through a reliable connection mode.
The assembled beam-column structure is prefabricated and manufactured in factories and installed and adjusted on site as a basic unit consisting of beams and columns. At present, the fabricated beam-column structure generally has high rigidity, which means that under the earthquake load, the rigidity of the structure is relatively high, and enough deformation and displacement cannot be generated to absorb the earthquake energy, so that the energy consumption capability is poor.
Therefore, a beam-column structure with self-resetting energy consumption capability is needed to improve the overall deformability and energy consumption capability, thereby improving the anti-seismic performance of the beam-column structure.
Disclosure of Invention
Aiming at the problems, the utility model aims to provide a beam column structure, which can effectively realize the relative rotation and relative dislocation of beam column connecting nodes through the cooperation of a first buffer device and a second buffer device and has better anti-seismic performance.
The technical scheme of the utility model is as follows: a beam-column structure comprising:
a column body, wherein one longitudinal side surface is provided with a column connecting piece; the column connecting piece comprises a column preset section preset in the column body and a column extending section which is connected with the column preset section and is positioned outside the column body; the column extension section comprises a first bottom plate, a first connecting block and a second connecting block, wherein one side of the first bottom plate is connected with the column preset section, and the first connecting block is arranged on the first bottom plate and positioned on the opposite side of the column preset section;
a beam body, wherein one longitudinal end surface is provided with a beam connecting piece; the beam connecting piece comprises a Liang Yushe section pre-buried in the beam body and a beam extending section which is connected with the beam preset section and is positioned outside the beam body; the beam extension section comprises a second bottom plate, a second connecting block and a second connecting block, wherein one side of the second bottom plate is connected with the beam preset section, and the second connecting block is arranged on the second bottom plate and positioned on the opposite side of the beam preset section;
the column body and the beam body are of an assembled structure, and the column extension section is connected with the beam extension section through a first buffer device for counteracting relative rotation and a second buffer device for counteracting dislocation; the plurality of first buffer devices are arranged between the first bottom plate and the second bottom plate at intervals; the two second buffer devices are respectively used for connecting the first connecting block and the second connecting block; the second buffer device comprises a first connecting strip connected with the first connecting block, a second connecting strip connected with the second connecting block, and a third connecting strip used for connecting the first connecting strip, the second connecting strip and forming a Z-shaped structure with the first connecting strip and the second connecting strip, wherein the first connecting strip, the second connecting strip and the third connecting strip are made of soft steel materials.
Further, the column body is a precast reinforced concrete column, and the beam body is a precast reinforced concrete beam.
Further, the first bottom plate and the second bottom plate are arranged correspondingly.
Further, the four first buffering devices are distributed at four corners of the opposite surfaces of the first bottom plate and the second bottom plate.
Further, the first buffer device adopts any one of a hydraulic damper or a magnetic damper energy dissipation device.
Further, one of the surfaces of the first connection block is in close contact with one of the surfaces of the second connection block.
Further, the first connecting block and the second connecting block are in the same structure, the lower surface of the first connecting block is in close contact with the upper surface of the second connecting block after being overlapped, the two second buffering devices are respectively arranged at the front end and the rear end of the first connecting block and the second connecting block, one end of each second buffering device is arranged on the first connecting block, and the other end of each second buffering device is arranged on the second connecting block.
Further, bolt holes for connecting and anchoring bolts are formed in the first bottom plate, the first connecting block, the second bottom plate and the second connecting block.
The working principle of the utility model is as follows: when the column extending section and the beam extending section rotate and are dislocated, energy is consumed through the first buffer device, and the seismic energy is consumed. When the column extending section and the beam extending section are staggered, corresponding staggered plastic strain is generated through the second buffer device to consume energy, and the second buffer device has self-resetting capability.
Compared with the prior art, the utility model has the beneficial effects that: when the beam and column structure provided by the utility model is in left-right dislocation, the second buffer device is in corresponding dislocation to consume energy, so that the beam and column structure has self-resetting capability and is convenient to detach; when the relative rotation occurs, the hydraulic buffer device consumes energy and consumes earthquake energy; the connecting node of the beam column structure can be effectively protected, and damage to the connecting node is prevented. And the second damping means dissipates energy through a working stroke of horizontal displacement. Meanwhile, in the working process, the damper can generate slight vertical tension and compression deformation in the horizontal displacement process. Such a design ensures that the damper can operate stably under predetermined operating conditions and can exert energy-consuming properties permanently. Meanwhile, the design can also effectively avoid out-of-plane instability, so as to prevent the damper from exiting the working state in advance.
