Description

Technical Field

[0001] The utility model relates to the field of building construction, and particularly refers to a connecting structure between a frame beam and a frame column. Background Art

[0002] A frame beam refers to a beam with both ends connected to frame columns, or a beam with both ends connected to shear walls but with a span-depth ratio not less than 5. The strength of the overall structure mainly depends on the connection and reinforcement strength between the frame beam and the frame column.

[0003] For the traditional connection and reinforcement structure between a frame beam and a frame column, steel bars are implanted in the frame column and then tied and welded to connect with the frame beam to complete the connection between the frame beam and the frame column. When using this connection method and encountering a frame column with small cross-section and dense steel bars, due to the fact that the frame column itself cannot meet the requirements of the implanted steel bar depth, or the internal steel bars in the frame column are too dense to implant steel bars, the connection between the frame beam and the frame column is restricted and cannot be completed. Even if they are connected together, there are problems of unstable connection. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a connecting structure between a frame beam and a frame column, so as to solve the problem that the connection between a frame beam and a frame column in the prior art is easily restricted.

[0005] To achieve the above purpose, the utility model provides a connecting structure between a frame beam and a frame column, including a frame column main body, and implanting steel bar grooves are circumferentially and annularly formed on the frame column main body;

[0006] A frame beam main body, and the existing main steel bars on both sides inside the frame beam main body extend from the end of the frame beam main body;

[0007] The end of the frame beam main body is close to the frame column main body, and the main steel bars extending from both sides inside the frame beam main body respectively bypass from both sides of the frame column main body and are welded together on the side of the frame column main body facing away from the frame beam main body;

[0008] Wherein the main steel bars bypassing the frame column main body fall inside the implanting steel bar grooves.

[0009] By adopting this technical solution, the main steel bars extending from both sides inside the frame beam main body are introduced into the implanting steel bar grooves formed on the surface of the frame column main body, and then the two main steel bars forming a hugging trend on the frame column main body are welded together. In this way, the connection between the frame beam main body and the frame column main body is completed through the hugging acting force of the main steel bars and the limiting acting force of the implanting steel bar grooves. It can not only adapt to the variable cross-section connection between the frame beam and the frame column, but also adapt to the situation where the internal steel bars in the frame column are dense and the implanting of steel bars cannot be completed for connection, thus solving the problem that the connection between the frame beam and the frame column is easily restricted.

[0010] Furthermore, the depth of the anchor groove is greater than twice the length of the existing main reinforcement diameter in the frame beam body.

[0011] By adopting this technical solution, it is ensured that the main reinforcement connected by welding is completely placed inside the rebar groove, which can maximize the limiting effect of the rebar groove and achieve a semi-implicit connection.

[0012] Furthermore, a lap gap is formed between the end of the frame beam body and the frame column body, and grouting is solidified in the lap gap to form a lap block, and the lap block covers the main reinforcement exposed to the outside.

[0013] By adopting this technical solution, the overlap blocks formed by grouting consolidation can avoid exposing the main reinforcement, thereby increasing the aesthetics.

[0014] Furthermore, the overlap blocks are respectively fixed to the frame beam body and the frame column body as one body.

[0015] By adopting this technical solution, the connection strength between the frame beam body and the frame column body can be further increased.

[0016] Furthermore, a pouring gap is formed between the main reinforcement and the reinforcement groove, and quick-drying concrete is poured into the pouring gap.

[0017] By adopting this technical solution: after the quick-drying concrete is solidified, the relative stability between the main reinforcement and the reinforcement groove can be further increased, thereby increasing the connection stability between the frame beam body and the frame column body.

[0018] Furthermore, the surface formed by the quick-drying concrete after solidification is flush with the outer surface of the frame column body.

[0019] By adopting this technical solution, the surface of the main body of the frame column is guaranteed to be smooth after the quick-drying concrete is solidified.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. By adopting the method of slotting on the existing frame columns and cooperating with the main reinforcement at the ends of the frame beams, an interlocking limiting structure is formed, which can not only ensure the connection stability between the frame beams and the frame columns, but also meet the connection requirements of the variable-section and dense-reinforced frame columns and the frame beams, thus solving the problem that the connection between the frame beams and the frame columns is easily restricted.

[0022] 2. Compared with the existing rebar connection method, the connection form of hugging and limiting not only reduces the construction difficulty, but also has higher construction efficiency, which is beneficial to the rapid advancement of the project progress.

[0027] The opening depth of the rebar planting groove 4 is greater than twice the diameter of the existing main reinforcement 3 inside the frame beam main body 1; ensuring that the main reinforcements 3 connected by welding completely fall inside the rebar planting groove 4 can not only maximize the limiting effect of the rebar planting groove 4, but also achieve a semi-hidden connection.

[0030] A perfusion gap is formed between the main reinforcement 3 and the rebar planting groove 4, and quick-drying concrete is perfused in the perfusion gap; after the quick-drying concrete is consolidated, it can further increase the relative stability between the main reinforcement 3 and the rebar planting groove 4, thereby increasing the connection stability between the frame beam main body 1 and the frame column main body 2.

[0031] The surface formed after the quick-drying concrete solidifies is flush with the outer surface of the main body 2 of the frame column, ensuring the flatness of the surface of the main body 2 of the frame column.
