Description

Technical Field

[0001] This invention belongs to the field of concrete beam-column connection technology, specifically a prefabricated reinforced concrete beam-column joint connection structure. Background Technology

[0002] The prefabricated reinforced concrete column joint is a core component in prefabricated concrete structures, connecting precast reinforced concrete columns and beams. Through standardized design and reliable connection between factory-prefabricated components and on-site installation, it is a crucial node for ensuring the transfer of loads between beams and columns and the overall stability of the structure. It is equivalent to the "joint" of a prefabricated building, connecting precast beams and columns while ensuring the effective transfer of forces; it is a core element for structural safety.

[0003] Currently, the connections of reinforcing bars in prefabricated beam-column joints mostly employ mechanical connections, sleeve grouting connections, and welding connections. Mechanical connections transfer the force from one reinforcing bar to another through the mechanical interlocking of the reinforcing bar and the connector, making it an effective connection method. However, this method cannot guarantee the quality of the connectors during on-site construction, as the matching rate between the reinforcing bars and the prefabricated connectors in the factory is extremely low, making it difficult to ensure the stability of internal force transmission in the reinforcing bar connection. Sleeve grouting connections utilize a high-strength circular sleeve with internal concave and convex sections. The connecting reinforcing bars are inserted, and then a grouting machine injects a micro-expansion high-strength grout composed of cement, fine aggregate, expansion agent, and water-reducing agent. When the grout hardens, the sleeve and the reinforcing bar are firmly bonded together as a whole. However, in actual construction, the number of sleeves and their closed appearance make quality inspection difficult. Furthermore, the sleeve connections are complex, and the grout volume cannot be controlled, resulting in a significant time and labor cost during construction. Welding connections use electric welding equipment to extend or cross-connect the reinforcing bars along the axial direction. However, the welded reinforcing bars will exhibit uneven internal stress, leading to increased brittleness and hardness. Moreover, on-site operations require specialized equipment, consume a lot of energy, and are prone to environmental pollution, placing high demands on the construction environment. The traditional connection methods mentioned above all suffer from problems such as complex structure and numerous construction procedures.

[0004] Therefore, the present invention provides a prefabricated reinforced concrete beam-column joint connection structure. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention solves at least one technical problem mentioned in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a prefabricated reinforced concrete beam-column joint connection structure, including a concrete column and a concrete beam. Multiple outer walls of the concrete column can be detachably installed with concrete beams. Fixed steel plates are detachably installed between the concrete beams and the concrete column. The fixed steel plates are provided with fasteners for limiting their own position on the outside. The fixed steel plates located on both sides of the concrete beam can be connected by the fasteners, and the fixed steel plates are bonded to the outer walls of the concrete column.

[0007] The fasteners include tie bolts and fastening nuts. The fixing steel plate has an installation hole on the side near the concrete beam, and the concrete beam has a through hole on the side near the fixing steel plate. The tie bolts are fixedly installed in the inner cavity of the through hole. The two ends of the tie bolts pass through the through hole and extend to the outside of the concrete beam. The two ends of the multiple tie bolts are all fitted with fastening nuts that limit the position of the fixing steel plate through threaded engagement.

[0008] One side of each of the fixed steel plates has an injection hole, and the other side of the fixed steel plates near the injection hole has an overflow hole, which is located directly above the injection hole.

[0009] A slotted plate is fixedly installed on the side of the fixed steel plate near the concrete beam. The slotted plate is designed with a U-shaped structure.

[0010] A connecting steel plate is slidably installed between each two adjacent fixed steel plates, and a reinforcing member that strengthens the connection between the connecting steel plate and the fixed steel plate can be detachably installed.

[0011] Both the fixed steel plate and the connecting steel plate are designed with an L-shaped structure. The end of the fixed steel plate away from the concrete beam points to the corner of the concrete column. The connecting steel plate has a sliding groove on the side close to the fixed steel plate. A sliding plate is slidably installed in the inner cavity of the sliding groove. The end of the sliding plate close to the opening of the sliding groove is fixedly connected to one end of the fixed steel plate.

[0012] The reinforcing component includes a reinforcing plate. Two reinforcing plates are symmetrically installed between the connecting steel plate and the fixing steel plate. Connecting ear plates are fixedly installed on the top and bottom of the reinforcing plates. A through hole is opened on one side of the connecting ear plate. A limit bolt is detachably installed in the inner cavity of the through hole. A limit nut for connecting two adjacent reinforcing plates is installed on the outside of the limit bolt through thread engagement.

[0013] The reinforcing plate is designed with a U-shaped structure and is made of metal.

[0014] Two top pressure plates are symmetrically arranged at the top and bottom of both the fixed steel plate and the connecting steel plate. The top of the top pressure plate and the inner wall of the reinforcing plate near the top pressure plate are both inclined.

[0015] H-shaped steel plates are fixedly installed at one end of multiple concrete beams. Multiple side walls of the concrete columns are provided with mounting grooves that are compatible with the H-shaped steel plates. Limiting steel plates are fixedly installed on the inner walls of the mounting grooves away from their openings. Multiple limiting posts are fixedly installed on the side of the limiting steel plates near the openings of the mounting grooves. Multiple through holes that are compatible with the limiting posts are provided on the side of the H-shaped steel plates away from the concrete beams.

[0016] A load-bearing plate is installed between the concrete column and multiple concrete beams. Insert plates are fixedly installed at both ends of the multiple load-bearing plates. Fixing plates are fixedly installed on multiple side walls of the concrete column and multiple side walls of the concrete beams. Positioning grooves that match the insert plates are opened on one side of the multiple fixing plates.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. Fixing components can be used to fix the symmetrically installed steel plates on both sides of the concrete beam to the two sides of the concrete beam. Multiple steel plates installed on both sides of the concrete beam can be connected to the outer wall of the concrete column by adhesive bonding. This can realize the connection between the end of the concrete beam and the outer wall of the concrete column, reduce the complexity of the connection between the concrete beam and the concrete column, and reduce the number of construction procedures for the concrete beam and the concrete column.

[0019] 2. Through the reinforcement, the initial connection between multiple concrete beams and the outer wall of concrete columns can be achieved, and the connected concrete beams and concrete columns are reinforced to prevent deformation or separation from the outer wall of the concrete column when the top of the concrete beam is bearing heavy objects, thereby improving the stability of the connection between the concrete beams and concrete columns.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figure 1-8 As shown, the embodiment of the present invention includes a concrete column, with multiple side walls symmetrically provided with fixed steel plates 1. A concrete beam can be detachably installed between any two adjacent fixed steel plates 1. Concrete beams can be detachably installed on all four side walls of the concrete column. When one end of the four concrete beams is connected to the outer wall of the concrete column, the required load-bearing beam can be constructed on the top of the concrete beams.

[0033] Two adjacent concrete beams are each provided with a fixed steel plate 1 on one side. The two adjacent fixed steel plates 1 are fixedly connected at one end. After the two fixed steel plates 1 are connected at one end, they can form a structure similar to an M-shape.

[0034] Mounting holes are provided on the side of the fixing steel plate 1 near the concrete beam. A through hole is provided on the side of the concrete beam near the fixing steel plate 1. Tie bolts 3 are fixedly installed inside the through hole. Both ends of the tie bolts 3 penetrate the through hole and extend to the outside of the concrete beam. Both ends of the multiple tie bolts 3 are threaded and fitted with fastening nuts to limit the position of the fixing steel plate 1. When connecting the outer wall of the concrete column to one end of the concrete beam, the four concrete beams are first hoisted until one end of each beam is flush with the outer wall of the concrete column, ensuring that the tops of the four beams are level and aligned. A horizontal line is drawn, and then two fixed steel plates 1 are placed between two adjacent concrete beams. Next, one of the fixed steel plates 1 is fitted onto the outside of the tie bolt 3 through the mounting hole. Then, the other fixed steel plate 1 is fitted onto the outside of the adjacent tie bolt 3 through the mounting hole. Then, the fastening bolt is fitted onto the outside of the tie bolt 3 through the threaded engagement, and the fastening nut is continuously rotated until one end of the fastening nut presses against the outer wall of the fixed steel plate 1, so that the outer walls of both fixed steel plates 1 are in contact with the outer wall of the concrete beam, thus realizing the connection between the two adjacent concrete beams.

[0035] Multiple concrete beams have H-shaped steel plates 14 fixedly installed at one end. Multiple side walls of the concrete columns have mounting grooves 16 adapted to the H-shaped steel plates 14. Limiting steel plates 15 are fixedly installed on the inner walls of the mounting grooves 16 away from their openings. Multiple limiting posts 17 are fixedly installed on the side of the limiting steel plates 15 closest to the opening of the mounting grooves 16. Multiple through holes adapted to the limiting posts 17 are opened on the side of the H-shaped steel plates 14 away from the concrete beams. When one end of the concrete beam is fitted against one side of the concrete column, the installation... The H-shaped steel plate 14, installed at one end of the concrete beam, is first inserted into the inner cavity of the mounting groove 16 until the end of the H-shaped steel plate 14 away from the concrete beam is in contact with the side of the limiting steel plate 15 near the opening of the mounting groove 16. Multiple limiting posts 17 are simultaneously inserted into the inner cavities of multiple through holes. Thus, with the cooperation of the H-shaped steel plate 14 and multiple limiting posts 17, the concrete beam is prevented from detaching from the side wall of the concrete column under the action of gravity, thereby improving the stability of the concrete beam and concrete column when connected by tie bolts 3.

[0036] When the end of the H-shaped steel plate 14 away from the concrete beam is attached to the side of the limiting steel plate 15 near the opening of the mounting groove 16, one end of the concrete beam and the outer wall of the concrete column are tightly attached to each other, preventing gaps between the concrete beam and the concrete column from reducing the firmness of the two connections.

[0037] When the two fixed steel plates 1 are connected to the outer wall of the concrete beam with the help of tie bolts 3 and fastening nuts, the connection point of the two fixed steel plates 1 is on the same horizontal line as the diagonal of the concrete column. This prevents the uneven stress and displacement that may occur after one end of the two adjacent concrete beams is attached to the side wall of the concrete column, thus improving the stability of the connection between the two concrete beams and the outer wall of the concrete column.

[0038] A gap plate 7 is fixedly installed on the side of the fixed steel plate 1 near the concrete beam. When the fixed steel plate 1 is squeezed by the fastening nut and moves towards the concrete beam, until the outer wall of the gap plate 7 is tightly attached to the outer wall of the concrete beam, the fixed steel plate 1 can be fixedly connected to the outer wall of the concrete beam by the fastening nut. Under the action of the gap plate 7, the outer wall of the fixed steel plate 1 and the outer wall of the concrete beam are kept at a certain distance, allowing the structural adhesive to flow between the fixed steel plate 1 and the concrete beam.

[0039] A grouting hole 6 is located on one side of the fixed steel plate 1. Multiple fixed steel plates 1 have overflow holes 5 on their sides near the grouting hole 6. The overflow holes 5 are located directly above the grouting hole 6. After the fixed steel plate 1 is connected to the outer wall of the concrete beam via the fastening nuts and tie bolts 3, a reinforcing member is used to connect the connecting steel plate 2 and the fixed steel plate 1. Then, the grouting end of the grouting applicator is inserted into the grouting hole 6, and structural adhesive is continuously injected between the connecting steel plate 2 and the concrete column. Due to the fluidity of the structural adhesive, it flows from the connecting steel plate 2 to the fixed steel plate 1 and the concrete column until it overflows from the overflow hole 5. The overflow is considered complete within 3 seconds. By ensuring proper compaction, the connection between concrete beams and columns can be achieved, thus optimizing the reinforcement method to a simple and efficient steel plate sleeve structure. This improves reinforcement efficiency, structural quality, and connection tightness, while significantly reducing construction time, saving materials, and minimizing waste generated from wet concrete work. It solves the problems of long construction time and high risk of structural re-reinforcement associated with traditional reinforcement methods. Furthermore, the steel plate sleeve is factory-made, ensuring good overall stability and strong load-bearing capacity. This reinforcement method is simple, scientific, and reasonable, with convenient construction and fast and reliable gluing of the steel plate sleeve, ensuring stability, safety, and reliability during the re-reinforcement process. It effectively solves a major problem that has long plagued the industry, representing an innovative product in structural reinforcement with strong practicality and promising market application prospects.

[0040] The tie bolts 3, the glue injection hole 6, the glue overflow hole 5, and the fastening bolts constitute the fasteners. The fasteners can fix the symmetrically installed fixing steel plates 1 on both sides of the concrete beam to both sides of the concrete beam. The fixing steel plates 1 installed on both sides of the concrete beam can be connected to the outer wall of the concrete column by adhesive bonding. This can realize the connection between the end of the concrete beam and the outer wall of the concrete column, reduce the complexity of the connection between the concrete beam and the concrete column, and reduce the number of construction procedures for the concrete beam and the concrete column.

[0041] After the four concrete beams are hoisted to the outside of the concrete columns, the surface dust of the concrete beams and columns is cleaned to prevent the dust from mixing with the structural adhesive, which could cause air bubbles or bulges in the adhesive and increase its adhesion, making it unable to firmly adhere to the outer surface of the concrete beams and columns.

[0042] The gap plate 7 is designed with a U-shaped structure, which can increase the contact area between the gap plate 7 and the outer wall of the concrete beam and prevent the outer wall of the fixed steel plate 1 from deforming when the fastening nut squeezes the outer surface of the fixed steel plate 1.

[0043] Through the above embodiments, different construction needs and different building spaces result in different widths of concrete beams and concrete columns. According to the different sizes of concrete columns, the distance between the two fixed steel plates 1 needs to be adjusted. If the distance between two adjacent fixed steel plates 1 cannot be adjusted, after one fixed steel plate 1 is connected to the outer wall of the concrete beam, the other fixed steel plate 1 cannot be sleeved on the outside of the adjacent tie bolt 3 through the mounting hole, thus making it impossible to connect two adjacent concrete beams through the two fixed steel plates 1.

[0044] A connecting steel plate 2 is slidably installed between each of the two adjacent fixed steel plates 1. A reinforcing member is detachably installed between the connecting steel plate 2 and the fixed steel plate 1 to enhance the connection strength between them. After the fixed steel plate 1 is connected to the outer wall of the concrete beam, the reinforcing member is sleeved between the connecting steel plate 2 and the fixed steel plate 1 and then fixed. This not only realizes the connection between the connecting steel plate 2 and the fixed steel plate 1, but also improves the connection strength between the connecting steel plate 2 and the fixed steel plate 1, preventing the connection between the connecting steel plate 2 and the fixed steel plate 1 from breaking when a load-bearing beam is added to the top of the concrete beam.

[0045] Both the fixed steel plate 1 and the connecting steel plate 2 are set as L-shaped structures, and the end of the fixed steel plate 1 away from the concrete beam points to the corner of the concrete column. The fixed steel plate 1 can be detachably installed on both sides of the four concrete beams. The connecting steel plate 2 between two adjacent fixed steel plates 1 is located at the corner of the concrete column. When the outer wall of the fixed steel plate 1 is connected to the outer wall of the concrete beam, the corner of the connecting steel plate 2 is on the same horizontal line as the diagonal of the concrete beam, so that the side of the connecting steel plate 2 closest to the concrete column is parallel to the outer wall of the concrete column.

[0046] To solve the above technical problems, a sliding groove is provided on the side of the connecting steel plate 2 near the fixed steel plate 1. A sliding plate 8 is slidably installed in the inner cavity of the sliding groove. One end of the sliding plate 8 near the opening of the sliding groove is fixedly connected to one end of the fixed steel plate 1. When one of the fixed steel plates 1 is sleeved on the outside of the tie bolt 3 through the mounting hole, the connecting steel plate 2 is pulled. At this time, the sliding plate 8 slides along the sliding groove until the middle of the mounting hole on the outer wall of the other fixed steel plate 1 and the middle of the adjacent tie bolt 3 are on the same horizontal line. Then, the other fixed steel plate 1 is pushed until one end of the tie bolt 3 is inserted into the interior of the mounting hole. This is beneficial for adjusting the distance between the two adjacent fixed steel plates 1 according to the distance from the side wall of the concrete beam to the corner of the concrete column, so that the connection of the two adjacent concrete beams can be achieved.

[0047] The reinforcing components include reinforcing plates 4. Two reinforcing plates 4 are symmetrically installed between the connecting steel plate 2 and the fixed steel plate 1. Connecting ear plates 11 are fixedly installed on the top and bottom of the reinforcing plates 4. A through hole is opened on one side of the connecting ear plate 11. A limit bolt 9 is detachably installed in the inner cavity of the through hole. A limit nut 10 for connecting the two adjacent reinforcing plates 4 is installed on the outside of the limit bolt 9 through thread engagement. After the fixed steel plate 1 is connected to the outer wall of the concrete beam by fastening the nut, the two reinforcing plates 4 are symmetrically placed between the connecting steel plate 2 and the fixed steel plate 1, and the adjacent sides of the two reinforcing plates 4 are respectively attached to the outer walls of the connecting steel plate 2 and the fixed steel plate 1. Then the positions of the two reinforcing plates 4 are adjusted until the opening ends of the through holes at the top and bottom of the two adjacent reinforcing plates 4 are on the same horizontal line. Then the small end of the limit bolt 9 is closed. Insert the bolt 9 through one of the through holes until the small end of the limiting bolt 9 passes through the other through hole and extends to the outside of the other reinforcing plate 4. Then, fit the limiting nut 10 onto the small end of the limiting bolt 9 and continue to rotate the limiting nut 10 until one end of the limiting nut 10 and the large end of the limiting bolt 9 are in contact with the outer walls of the two adjacent connecting ear plates 11. This connects the two adjacent reinforcing plates 4. At the same time, the large end of the limiting bolt 9 and the limiting nut 10 continuously provide compressive force to the two adjacent connecting ear plates 11, allowing the outer wall of the reinforcing plate 4 to fit tightly with the outer walls of the connecting steel plate 2 and the fixed steel plate 1. This also wraps the gap between the connecting steel plate 2 and the fixed steel plate 1, improving the strength of the connection between the connecting steel plate 2 and the fixed steel plate 1 and preventing the slide plate 8 from breaking or deforming due to excessive force.

[0048] The reinforcing plate 4 is designed with a U-shaped structure. When the two reinforcing plates 4 are connected by the limiting bolts 9 and the limiting nuts 10, they can wrap the outside of the connecting steel plate 2 and the fixed steel plate 1, further increasing the strength of the connecting steel plate 2 and the fixed steel plate 1.

[0049] Two top pressure plates 12 are symmetrically arranged at the top and bottom of both the fixed steel plate 1 and the connecting steel plate 2. The top of the top pressure plate 12 and the inner wall of the reinforcing plate 4 near the top pressure plate 12 are both inclined. When the two reinforcing plates 4 are connected by the matching limit bolts 9 and limit nuts 10, the inclined inner wall of the reinforcing plate 4 is tightly attached to the inclined side wall of the top pressure plate 12. At this time, the top of the reinforcing plate 4 applies downward pressure to the top of the connecting steel plate 2 and the fixed steel plate 1, while the bottom of the reinforcing plate 4 applies upward thrust to the bottom of the connecting steel plate 2 and the fixed steel plate 1, thereby increasing the stress of the connecting steel plate 2 and the fixed steel plate 1 and preventing the top of the connecting steel plate 2 and the fixed steel plate 1 from bending under stress.

[0050] A load-bearing plate 13 is installed between a concrete column and multiple concrete beams. Insertion plates 18 are fixedly installed at both ends of each load-bearing plate 13. Fixing plates 19 are fixedly installed on multiple side walls of the concrete column and multiple side walls of the concrete beams. Each fixing plate 19 has a positioning groove on one side that matches the insertion plate 18. After one end of the concrete beam is connected to the side wall of the concrete column, the load-bearing plate 13 is placed between the concrete beam and the concrete column. Then, the insertion plates 18 installed at both ends of the load-bearing plate 13 are simultaneously inserted into the cavities of two adjacent positioning grooves. The installation effect is as follows: Figure 1 As shown, the load-bearing plate 13 can support the bottom of the concrete beam until the central axis of the load-bearing plate 13 coincides with the central axis of the concrete column and the concrete beam. This prevents the top of the concrete beam from deforming or collapsing when it is loaded with heavy objects, and further improves the stability of the connection between the concrete beam and the concrete column.

[0051] The reinforcing plate 4, connecting ear plate 11, H-shaped steel plate 14, limiting steel plate 15, limiting column 17, load-bearing plate 13, and fixing plate 19 constitute the reinforcing component. The reinforcing component enables the initial connection between multiple concrete beams and the outer wall of concrete columns, and strengthens the connected concrete beams and concrete columns to prevent deformation or separation from the outer wall of concrete columns when the top of the concrete beams bears heavy loads, thereby improving the stability of the connection between concrete beams and concrete columns.
