Abstract
Description
Technical Field
[0001] This invention relates to the field of inner ring beam-column joint technology, specifically to the modification and reinforcement structure and installation method of inner ring beam-column joint in building structures. Background Technology
[0002] The ring beams and structural columns together form a frame structure. They are connected by toothed joints, which first set back and then advance, tightly integrating the walls with the beams and columns to form an integrated load-bearing system. This structure can effectively resist horizontal loads such as wind pressure and seismic waves, and vertical loads such as floor live loads, preventing local cracking or collapse of the escalator walls. In the event of an earthquake or other sudden event, the ring beams and structural columns work together, forming a "frame-shear wall" structure through steel reinforcement anchoring and concrete pouring. This structure can significantly improve the overall stiffness and collapse resistance of the escalator building and reduce the damage to the escalator structure caused by earthquakes.
[0003] However, traditional inner-ring beam-column joints have the following drawbacks: Traditional inner ring beam-column joints have poor self-supporting capacity. Affected by the construction of the sinking beam, the longitudinal reinforcement of the column is displaced, which in turn leads to the displacement of the stirrups, reducing the safety of the escalator itself. Summary of the Invention
[0004] The purpose of this invention is to provide a structure and installation method for modifying and reinforcing the inner ring beam-column joint of a building structure, so as to solve the problem mentioned in the background art that the traditional inner ring beam-column joint has poor self-support capacity, and the longitudinal reinforcement of the column is displaced due to the impact of the beam sinking construction, which in turn leads to the displacement of the stirrups and reduces the safety of the escalator itself.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a structural modification and reinforcement structure for the inner ring beam-column joint of a building, including a floor slab, a support groove in the middle of the floor slab, an inner ring beam-column body fixedly installed on one side of the inner wall of the support groove, an anti-torsion steel reinforcement frame on one side of the inner ring beam-column body, a bottom beam reinforcement fixedly installed at the bottom end of one side of the anti-torsion steel reinforcement frame, several beam stirrup assemblies fixedly installed at the top end of the bottom beam reinforcement, several tie rod assemblies fixedly installed in the middle of one side of the anti-torsion steel reinforcement frame, a connecting assembly fixedly installed at the top end of one side of the anti-torsion steel reinforcement frame, each of the several beam stirrup assemblies including an installation plate and a beam stirrup body, the middle of the top end of the installation plate being fixedly connected to the bottom end of the beam stirrup body, positioning seats fixedly installed on both sides of the top end of the installation plate, height seats fixedly installed on both sides of the beam stirrup body, several rotating shafts rotatably connected inside the two positioning seats and the two height seats, and reinforcement components fixedly installed between two rotating shafts located on opposite sides.
[0006] As a preferred embodiment of the present invention, several reinforcing components each include two first angle plates and two second angle plates. One end of each of the two first angle plates is hinged to one end of each of the two second angle plates. A first limiting plate is fixedly installed on the other end of each of the two first angle plates, and a second limiting plate is fixedly installed on the other end of each of the two second angle plates. A connecting screw that is rotatably connected to the second limiting plate is threaded to the middle of each of the two first limiting plates. An angle rod is fixedly installed between the two second angle plates. The surfaces of the two first angle plates and the surfaces of the two second angle plates are in contact with the side of the rotating shaft. The angle plates are installed on both sides of the corresponding rotating shaft according to actual needs. Then, the user rotates the connecting screw to fix the two limiting plates together, thus completing the fixation between the angle plates. The reinforcing components reinforce the main body of the beam stirrups from the side, improving the stability of the main body of the beam stirrups.
[0007] As a preferred embodiment of the present invention, the surface of the mounting plate is threaded with mounting screws, and the mounting plate is fixedly connected to the bottom reinforcement of the beam by the mounting screws. The surfaces of the two mounting screws are threaded with mounting nuts. When the user tightens the mounting screws, the threads on the surface of the mounting screws match the threads on the inner wall of the mounting plate, so the mounting screws rotate and rise relative to the mounting plate, fixing the mounting plate to the bottom reinforcement of the beam.
[0008] As a preferred embodiment of the present invention, the connecting assembly includes a reinforcing frame and length rods. One end of each of the length rods is fixedly connected to one side of the reinforcing frame, and the other end of each length rod is slidably connected to a length shell.

The reinforcing frame is fixedly connected to the anti-torsion steel frame through the connecting screws. Several ground piles are engaged with the side of the inner ring beam column body directly opposite each other. When the user tightens the connecting screws, the threads on the surface of the connecting screws match the threads on the inner wall of the reinforcing frame. Therefore, the connecting screws rotate and translate relative to the reinforcing frame, fixing the reinforcing frame to the anti-torsion steel frame. The user slides the length rod along the length shell to adjust the position of the ground piles. The ground piles are inserted into the inner ring beam column body. When the user tightens the locking screws, the threads on the surface of the locking screws match the threads on the inner wall of the length shell. Therefore, the locking screws rotate and translate relative to the length shell, fixing the length shell and the length rod together.

Threaded holes are provided on the surfaces of the two first movable plates and the two second movable plates.
[0011] As a preferred embodiment of the present invention, the surface of the tie rod shell is threaded with assembly screws, and the tie rod shell is fixedly connected to the tie rod rod by the assembly screws. The two first movable plates are fixedly connected to the anti-torsion steel reinforcement frame on the side away from the first sliding plate, and the two second movable plates are fixedly connected to the inner ring beam and column body on the side away from the second sliding plate. The user slides the tie rod rod along the tie rod shell to adjust the length of the tie rod assembly. The user screws the assembly screws, and the threads on the surface of the assembly screws match the threads on the inner wall of the tie rod shell to fix the tie rod shell and the tie rod together. The user screws the screws through the threaded holes to install the movable plates on the tie rod assembly onto the anti-torsion steel reinforcement frame and the inner ring beam and column body respectively.
[0012] The installation method of the inner ring beam-column joint modification and reinforcement structure of the present invention includes the following steps: Step 1: Install the inner ring beam and column bodies: Install the inner ring beam and column bodies on the floor slab; Step 2: Install the connecting components: The user tightens the connecting screws to install the reinforcement frame on the anti-torsion steel frame. The user inserts the ground pile into the inner ring beam and column body and assembles the inner ring beam and column body with the anti-torsion steel frame. Step 3: Install the tie rod assembly: The user tightens the screws to fix the movable plate between the inner ring beam and column body and the anti-torsion steel frame; Step 4: Install the beam stirrup assembly: The user tightens the mounting screws to fix the mounting plate to the bottom reinforcement of the beam. The user then installs the beam stirrup body under the inner ring beam and column body, assembling the inner ring beam and column body together with the bottom reinforcement of the beam.
[0013] Compared with the prior art, the beneficial effects of the present invention are: By setting up connecting components, tie rod components, and beam stirrup components, and installing them sequentially on the outside of the inner ring beam and column body, the inner ring beam and column body is assembled with the anti-torsion steel reinforcement frame, which improves the support of the inner ring beam and column body itself and enhances the safety of the escalator. By setting up tie rod components, the newly added longitudinal bars and anti-torsion bars should be anchored into the ring beam or planted into the main beams of the frame columns on both sides to strengthen them without increasing the volume and improve the supporting capacity of the inner ring beams and columns.
