Description

Technical Field

[0001] This utility model relates to the field of beam and column reinforcement technology, specifically a reinforced concrete frame beam and column reinforcement node. Background Technology

[0002] Reinforced concrete frame beams and columns refer to structures composed of steel bars and concrete, mainly used to bear the vertical and horizontal loads of buildings. Frame beams and columns consist of reinforced concrete beams and reinforced concrete columns, which together form the load-bearing system of the building. Reinforced concrete frame beams and columns are widely used in various engineering structures such as houses, bridges, and hydraulic engineering. They are commonly used as supports for floors, piers, foundation columns, towers, and compression members of trusses. Reinforced concrete frame beams and columns are commonly used load-bearing structures in modern buildings, with high strength and stability, and are suitable for various building types. To avoid structural damage caused by long-term pressure at the joints of concrete beams and columns, a reinforced concrete frame beam and column joint reinforcement structure is proposed.

[0003] For example, the reinforced concrete frame beam-column joint reinforcement structure disclosed in the authorization announcement number CN220504626U includes a frame beam assembly, a main frame assembly, a first auxiliary frame and a second auxiliary frame;

[0004] Although it achieves the following during use, symmetrical holes are opened on both sides of the vertical beam, and symmetrical holes are opened on the opposite surfaces of the holes on the horizontal beam and the vertical beam. The bolts on the vertical plate and the horizontal plate are connected to the holes, so that the vertical plate and the horizontal plate can be fixed at the included angle of the two sides of the horizontal beam and the vertical beam, which makes the installation more convenient. The damper can consume energy and reduce the vibration of the building. By rotating the first hexagonal head on both sides, the first screw on both sides can be rotated, so that the first slider on both sides can drive the first L-shaped plate to slide inside the second slide groove, so that the first L-shaped plate on both sides can be locked at the included angle of the two horizontal beams and fixed. Individual adjustment can be made when the outer wall of the horizontal beam is uneven, further making the installation more convenient.

[0005] However, this does not solve the problem that existing beam and column reinforcement methods are not conducive to convenient linkage reinforcement of beams and columns during use, nor to the rapid disassembly and assembly of reinforcement devices and the increase of load-bearing support area, thus affecting the convenience of disassembly and assembly and the reinforcement effect. Utility Model Content

[0006] The purpose of this utility model is to provide a reinforced concrete frame beam-column reinforcement node to solve the problems mentioned in the background art, such as the inconvenience of convenient linkage reinforcement of beams and columns, the difficulty in quickly disassembling and assembling the reinforcement device and increasing the load-bearing support area, which affect the convenience of disassembly and assembly and the reinforcement effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reinforced concrete frame beam-column reinforcement node, comprising a concrete column and a concrete beam, wherein a concrete beam is installed at the top of the concrete column, a fixed frame is installed on the surface of the concrete column, four sets of second bolts are symmetrically installed at equal intervals on the side wall of the fixed frame, and the second bolts extend through the fixed frame into the interior of the concrete column, and a linkage arm is provided on the side wall of the fixed frame between the two sets of second bolts, and a hinge shaft is installed at the end of the linkage arm near the fixed frame, and the linkage arm is movably connected to the fixed frame through the hinge shaft, and a sliding frame is slidably installed on the surface of the concrete column below the fixed frame.

[0008] Preferably, a support block is installed at the end of the linkage arm away from the fixed frame, and the support block is fixedly connected to the linkage arm.

[0009] Preferably, each of the support blocks has a telescopic block symmetrically installed inside, and the telescopic block is slidably connected to the support block.

[0010] Preferably, each of the support blocks has three sets of locking bolts symmetrically installed at its bottom end, and the locking bolts extend into the interior of the telescopic block.

[0011] Preferably, the surface of each expansion block is equipped with three sets of first bolts at equal intervals, and the first bolts extend through the expansion block into the interior of the concrete beam.

[0012] Preferably, two sets of third bolts with equal spacing are installed on the side wall of the sliding frame, and the third bolts extend through the sliding frame into the interior of the concrete column.

[0013] Preferably, a rotating arm is installed on the side wall of each linkage arm, and an upper movable shaft is installed at the top of each rotating arm, and the rotating arm is movably connected to the linkage arm through the upper movable shaft.

[0014] Preferably, each of the rotating arms is equipped with a lower movable shaft at its bottom end, and the rotating arm is movably connected to the sliding frame through the lower movable shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the beam and column reinforcement not only realizes convenient linkage reinforcement of beams and columns, facilitates quick disassembly and assembly of reinforcement devices and increases the load-bearing support area, but also improves the convenience of disassembly and assembly and the reinforcement effect.

[0016] First, a fixed frame is installed at the connection point between the concrete column and the concrete beam. A second bolt is then installed on the surface of the fixed frame, securing it to the concrete column. Next, a sliding frame is installed on the surface of the concrete column. The sliding frame slides upwards, causing a rotating arm to rotate via a lower movable shaft. This rotating arm, in turn, causes a linkage arm to rotate around a hinge axis via an upper movable shaft. The linkage arm then rotates a support block, bringing it into contact with the bottom of the concrete beam. Finally, a third bolt is installed on the surface of the sliding frame, securing it to the concrete column. Through the coordinated action of the rotating arm and the linkage arm, the support block reinforces the concrete beam. Both the sliding and fixed frames are openable, allowing for convenient assembly and disassembly. This facilitates easy and rapid assembly and disassembly of the reinforcement device, enhancing the ease of installation and removal.

[0017] By loosening the locking bolts, the expansion block is pulled out from inside the support block. Then, the first bolt is installed on the surface of the expansion block, and the expansion block is fixedly connected to the concrete beam using the first bolt. This increases the load-bearing area of ​​the support block. Afterward, the locking bolts are tightened again to fix the expansion block and the support block. This method facilitates increasing the load-bearing support area and improves the reinforcement effect. Attached Figure Description
