Description
Technical Field
[0001] This utility model relates to the field of building node connection technology, specifically a beam-column node connection structure for a prefabricated concrete irregular column frame. Background Technology
[0002] The beam-column joint connection structure of a concrete irregular column frame refers to the connection between the irregular column and the beam, which is achieved by means of steel reinforcement anchorage, denser stirrups, and local reinforcement to ensure that the joint area has sufficient strength and ductility to cope with complex loads such as earthquakes and wind loads.
[0003] This is the area where beams and columns intersect. The concrete in this area bears the complex stresses transmitted from the beams and columns. It is internally reinforced with dense stirrups to restrain the concrete and improve its compressive strength and ductility. The longitudinal reinforcement of the beam extends into the joint, and its anchorage method and length must meet the design requirements to ensure that the tensile or compressive force of the beam can be effectively transferred to the joint. The longitudinal reinforcement of the column continuously passes through the joint to ensure the continuity of the column's vertical bearing capacity. The longitudinal reinforcement of the beam usually extends into the joint using methods such as bent anchorage and straight anchorage. However, it is difficult to strengthen it after connection, so the joint needs to withstand huge repeated loads. It is impossible to improve its ductility and energy dissipation capacity in time. Under repeated seismic forces, the joint is prone to failure, which may lead to partial or even overall structural collapse. At the same time, in areas with strong winds, wind loads will cause horizontal displacement and internal forces in the building structure, which cannot effectively improve its shear and bending resistance. Over time, cracks and deformations may appear at the joint, affecting the overall stability of the structure and reducing its ability to resist wind loads. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please refer to Figure 1A beam-column joint connection structure for a prefabricated concrete irregular column frame includes: a beam-column body 1, with two horizontal beams 2 and two longitudinal beams 3 installed on the outer wall of the beam-column body 1.
[0027] Please refer to Figure 2 - Figure 5 The reinforcement mechanism is located between the beam-column body 1 and the two horizontal beams 2 and two longitudinal beams 3, and is used to reinforce the two horizontal beams 2 and two longitudinal beams 3. The reinforcement mechanism includes an installation component, a load-bearing component, and a plug-in component. The installation component is located between the two horizontal beams 2 and two longitudinal beams 3 and is used to install the two horizontal beams 2 and two longitudinal beams 3 to the beam-column body 1. The load-bearing component is located on the outer wall of the beam-column body 1 and is used to support the two horizontal beams 2 and two longitudinal beams 3. The plug-in component is located on top of the load-bearing component and is used to plug the load-bearing component in. The installation component includes plug rods 19 fixed on opposite sides of the two longitudinal beams 3 and multiple limiting blocks 7 installed on opposite sides of the two horizontal beams 2. The multiple limiting blocks 7 are connected to the beam-column body 1. The two insert rods 19 extend into the interior of the beam-column body 1 and are inserted into the two longitudinal beams 3. The load-bearing component includes a reinforcing seat 4 installed on the outer wall of the beam-column body 1 and a movable seat 5 set on the top of the reinforcing seat 4. Multiple evenly distributed reinforcing columns 6 are fixed on the top of the reinforcing seat 4. The multiple reinforcing columns 6 are inserted into the movable seat 5. The insertion component includes a fixing groove opened on the top of the movable seat 5. A bidirectional screw 12 is installed inside the fixing groove. Two threaded blocks 13 are screwed onto the outer wall of the bidirectional screw 12. Insert plates 11 are fixed on the top of the two threaded blocks 13. The two insert plates 11 are inserted into the reinforcing columns 6. A drive component for driving the bidirectional screw 12 to rotate is provided between the bidirectional screw 12 and the movable seat 5.
[0028] The reinforcing seat 4 is installed on the outer wall of the beam-column body 1. The drive motor 17 drives the drive gear 16 to rotate, which in turn drives the driven gear 14 to rotate. The driven gear 14 then drives the bidirectional screw 12 to rotate, which in turn drives the two threaded blocks 13 to move in opposite directions. The movement of the two threaded blocks 13 causes the two insert plates 11 to move, separating them from the reinforcing column 6. After the insert plates 11 are separated from the reinforcing column 6, the movable seat 5 is installed synchronously by multiple reinforcing columns 6 to achieve the reinforcement effect. As the insert plates 11 move, they drive the moving blocks 15 to move. The cooperation between the moving blocks 15 and the moving slots makes the insert plates 11 more stable during movement.
[0029] Furthermore, such as Figure 2As shown, the reinforcing base 4 and the movable base 5 are fixed with insert blocks 8 and positioning plates 20 on opposite sides. The upper and lower ends of the two crossbeams 2 are provided with slots for insert blocks 8 to be inserted. The inside of the insert rod 19 is provided with positioning holes for the positioning plates 20 to be inserted. The outer wall of the reinforcing base 4 is fixed with two extension plates 9. The top of the two extension plates 9 is fixed with a locking block, which is inserted into the two longitudinal beams 3. Based on this, the insertion rod 19 is inserted through the positioning plate 20, so that the two crossbeams 2 and the two longitudinal beams 3 are more stable during installation. The crossbeams 2 are inserted through the two insert blocks 8.
[0030] Furthermore, such as Figure 5 As shown, the drive assembly includes a drive motor 17 installed inside the movable seat 5 and a drive gear 16 installed at the output end of the drive motor 17. A driven gear 14 is fixed to the outer wall of the bidirectional screw 12, and the driven gear 14 meshes with the drive gear 16. Based on this, the mutual meshing of the drive gear 16 and the driven gear 14 makes the transmission efficiency of the drive motor 17 to the bidirectional screw 12 higher, while reducing the overall space occupied and improving space utilization.
[0031] Furthermore, such as Figure 4 As shown, a protective plate 10 is fixed to the top of the movable seat 5. The protective plate 10 has a movable cavity for the insertion plate 11 to move inside. A movable block 15 is fixed to the top of the insertion plate 11. A movable groove for the movable block 15 to move is opened at the top of the movable cavity. Based on this, the protective plate 10 can cover the bidirectional screw 12 after the device is installed, thereby achieving the protective function.
[0032] Please also refer to... Figure 6 The movable seat 5 has an injection port 18 on one side, the insert block 8 has a connecting groove connected to the injection port 18 inside, and the crossbeam 2 has a receiving groove connected to the connecting groove inside.
[0033] The required reinforcing adhesive is injected into the connecting groove through the injection port 18, and the reinforcing adhesive is then transported to the receiving groove through the connecting groove, thereby further reinforcing the crossbeam 2 after installation.
