Description

Technical Field

[0001] This utility model relates to the field of prefabricated beam and column connection structure technology, and in particular to a connection structure for prefabricated beams and columns. Background Technology

[0002] Prefabricated buildings manufacture beams and columns using precast concrete, which are then assembled on-site, significantly shortening the construction cycle. Connecting components are typically used between beams and columns, such as connectors at the ends of beams and mounting holes at the ends of columns for these connectors. The connectors are then inserted into these holes, and concrete grouting completes the connection. However, this connection strength is often low. In practice, reinforcement structures are usually added, such as steel connecting sleeves fitted onto the ends of beams and fixed to the columns to strengthen the connection. These connecting sleeves are exposed to the outside of the structure and are highly susceptible to environmental factors, such as corrosion in high-humidity environments, leading to a shortened service life. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a prefabricated connection structure for beams and columns, which solves the problem that exposed connection reinforcement structures in existing technologies are prone to corrosion, thus affecting service life.

[0004] According to an embodiment, a prefabricated beam and column connection structure is provided, comprising a column and a pair of beams. One end of the column has a through-hole penetrating its opposite side. One end of each beam has a connector that abuts into the through-hole, and the two connectors on the two beams abut against each other within the through-hole. A first filling groove is recessed at the end face of the column with the through-hole. Multiple first connecting rods, extending downwards into the through-hole and passing through the two connectors respectively, are disposed within the first filling groove. The first filling groove is also filled with concrete. In this solution, connectors are provided at the ends of the beams, inserted into the through-holes, and the two connectors of the two beams abut against each other within the through-holes, forming a single unit. Simultaneously, the two connectors are reinforced and fixed within the column by the first connecting rods. Finally, the first connecting rods are sealed with concrete, ensuring that the reinforcing connection structure is located within the column structure and is unaffected by the external environment. Therefore, this solves the problem in the prior art where exposed reinforcing connection structures are prone to corrosion, affecting service life.

[0005] Furthermore, the connector includes a fixed section fixed to the crossbeam and a mating section detachably connected to the fixed section. The fixed section has a recessed mounting groove on its end face away from the crossbeam, and the mating section has a mating part that abuts into the mounting groove. The first connecting rod also passes through the fixed section and the mating part.

[0006] Furthermore, an abutment surface is provided between the two docking sections for them to abut against each other.

[0007] Furthermore, the two abutting surfaces are inclined, and a second connecting rod is provided in the first filling groove, which penetrates downward through the mounting through hole and passes through the two abutting surfaces in sequence.

[0008] Furthermore, both the first connecting rod and the second connecting rod are inserted downwards into the bottom surface of the mounting through hole.

[0009] Furthermore, a connecting through hole is provided between the inner bottom surface of the mounting groove and the mounting through hole.

[0010] Furthermore, a second filling groove communicating with the through hole is recessed on the top surface of the mounting hole.

[0011] Furthermore, it also includes a pair of reinforcing members, each including a horizontal arm and a vertical arm fixed perpendicularly to the horizontal arm, the horizontal arm and the vertical arm being detachably connected to one side of the column and the bottom surface of one of the crossbeams, respectively.

[0012] Furthermore, a third connector is provided between the two vertical arms, penetrating the column.

[0013] Furthermore, a fourth connector is provided between the crossarm and the crossbeam connected to it.

[0014] Compared with the prior art, the present invention has the following beneficial effects: An installation through hole is provided on the column for the connector at the end of the crossbeam to be inserted. The two connectors of the two crossbeams abut in the installation through hole and are respectively fixed in the column by the first connecting rod. Finally, the first connecting rod is sealed with concrete, so that the connection reinforcement structure is located in the column structure and is not affected by the external environment. Therefore, it solves the problem in the prior art that the exposed connection reinforcement structure is prone to corrosion and affects the service life. Attached Figure Description

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3As shown, this embodiment provides a prefabricated beam and column connection structure, which includes a column 1 and a pair of beams 2. One end of the column 1 is provided with a mounting through hole penetrating its opposite side. One end of the beam 2 is fixedly provided with a connector 3 that abuts into the mounting through hole, and the two connectors 3 on the two beams 2 abut against each other in the mounting through hole. The end face of the column 1 with the mounting through hole is recessed with a first filling groove 4. Multiple first connecting rods 5 are provided in the first filling groove 4, which penetrate downward into the mounting through hole and pass through the two connectors 3 respectively. The first filling groove 4 is also filled with concrete.Similar to existing technologies, both the crossbeam 2 and column 1 in this solution are prefabricated components. The difference lies in the fact that the connector 3 in this solution is a two-part structure, specifically including a fixing section 6 fixed to the crossbeam 2, and a detachable connecting section 7. The fixing section 6 has a recessed mounting groove on its end face facing away from the crossbeam 2, and the connecting section 7 has an abutting part 8 that fits into the mounting groove. The first connecting rod 5 also passes through the fixing section 6 and the abutting part 8. The first connecting rod 5 can be made of steel bolts, and pre-drilled holes for the first connecting rod 5 to pass through are provided on the corresponding crossbeam 2 and column 1 structures. After the first connecting rod 5 and the second connecting rod 9 are assembled, concrete is filled into the first filling groove 4 to complete the connection. This arrangement allows the connector 3 to be fixed to the column 1 via the first connecting rod 5. Inside column 1, the connecting reinforcement structure (first connecting rod 5, connector 3) is located inside column 1, unaffected by the external environment. This solves the problem in existing technologies where exposed connecting reinforcement structures are prone to corrosion, affecting service life. In a further embodiment, the connector 3 abuts within the mounting through hole, forming a single unit. Simultaneously, the first connecting rod 5 reinforces and fixes the two connectors 3 within column 1. Finally, concrete is used to seal the first connecting rod 5, ensuring the connecting reinforcement structure is located within the column 1 structure. In an even more detailed embodiment, the abutment of the connector 3 is achieved through an abutment part 8, which has an inclined abutment surface. The two abutment surfaces abut within the mounting through hole. A second connecting rod 9 is also provided in the first filling groove 4, which penetrates downward through the installation through hole and passes through the two abutting surfaces in sequence, further strengthening the connection between them. This, together with the first connecting rod 5, further strengthens the overall connection (the second connecting rod 9 is connected in the same way as the first connecting rod 5). Specifically, although the abutting surfaces are in contact, there is still a small gap between them. Similarly, there is also a corresponding small gap between the connector 3 and the installation through hole. The concrete filling the first filling groove 4 can flow into the gap through the pre-set hole through which the first connecting rod 5 passes (the inner diameter of the reserved hole is larger than the outer diameter of the first connecting rod 5 and the second connecting rod 9, so there is a gap to facilitate assembly, and at the same time, the reserved hole and the first connecting... The gap between rod 5 and the second connecting rod 9 also provides a channel for concrete, and finally a concrete layer is formed inside the hole to wrap the first connecting rod 5 and the second connecting rod 9, strengthening the connection structure. In order to make the concrete enter the installation through hole and the corresponding gap more efficiently, a connecting through hole 10 is also provided between the inner bottom surface of the installation groove and the installation through hole. This allows the concrete to seep downward during the filling process and finally fill all the gaps. During the actual construction, concrete will seep out from both ends of the installation through hole. This can be used to determine whether the internal gap has been filled with concrete. If there is seepage, it can be sealed externally with a sealant, such as setting wooden strips to block the gaps at both ends of the installation through hole to prevent further seepage. Finally, the sealant can be removed after solidification.

[0018] like Figure 1-3 As shown, both the first connecting rod 5 and the second connecting rod 9 are inserted downwards into the bottom surface of the mounting through hole. Thus, the first connecting rod 5 passes through the fixed section 6 and the abutment part 8, and the second connecting rod 9 also passes through the two abutment parts 8, thereby further improving their connection strength. Furthermore, a second filling groove 11, which communicates with the through hole 10, is recessed on the top surface of the mounting through hole. This filling groove allows concrete to enter and then seep downwards into the corresponding gaps. When filling the concrete, a vibrating device (such as a concrete vibrator) is needed to vibrate the concrete so that the concrete can seep downwards smoothly to fill the second filling groove 11 and the corresponding gaps.

[0019] like Figure 1 , 3 As shown, to further enhance the stability of the overall structure, an L-shaped reinforcing member 12 is provided between the crossbeam 2 and the column 1. Specifically, the reinforcing member 12 includes a horizontal arm 13 and a vertical arm 14 fixed perpendicularly to the horizontal arm 13. The horizontal arm 13 and the vertical arm 14 are detachably connected to one side of the column 1 and the bottom surface of one of the crossbeams 2, respectively. That is, the reinforcing member 12 plays an auxiliary role in strengthening the connection between the two. However, compared with the connecting sleeve in the prior art, the reinforcing member 12 can be replaced and maintained more conveniently. More specifically, a third connecting member 15 penetrating the column 1 is provided between the two vertical arms 14, and a fourth connecting member 16 is provided between the horizontal arm 13 and the crossbeam 2 connected thereto. The third connecting member 15 and the fourth connecting member 16 can be bolts, wherein the third connecting member 15 can be a double-ended bolt penetrating the vertical arm 14 and the column 1.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
