[0015] 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.

[0016] Please see Figure 1-3 This utility model provides an implementation scheme: In the construction process of modern prefabricated buildings, in order to improve the construction efficiency of prefabricated buildings, it is necessary to use the combination of steel bars and sleeves for the assembly of concrete frame columns 1. However, at present, the steel bar sleeve combination mainly adopts the insertion sleeve combination. However, this insertion sleeve combination requires manual guidance and setting, so the operation is relatively cumbersome.

[0017] According to the instruction manual Figure 1-3 As can be seen, in order to address the above problems, this application discloses a prefabricated concrete frame column 1 steel bar sleeve, including a concrete frame column 1 and a building foundation 2. The concrete frame column 1 is assembled separately on the building foundation 2. The building foundation 2 is provided with a plurality of connecting steel bars 3 arranged in a matrix. The concrete frame column 1 is provided with a plurality of connecting sleeves 4 corresponding to the plurality of connecting steel bars 3. Through the corresponding installation of the connecting steel bars 3 and the connecting sleeves 4, the building foundation 2 supports and fixes the concrete frame column 1. Specifically, the aforementioned multiple connecting sleeves 4 are arranged in a matrix on the bottom surface of the concrete frame column 1. The multiple connecting sleeves 4 are embedded in the concrete frame column 1, and only the openings of the multiple connecting sleeves 4 are exposed. In this way, when the connecting sleeves 4 are fitted onto the connecting steel bars 3, the assembly of the concrete frame column 1 is achieved through the combination of the connecting sleeves 4 and the connecting bolts. In order to facilitate the installation and improve the installation efficiency, a pair of guide sleeves 5 are provided on both sides of the concrete frame column 1. The pair of guide sleeves 5 serve as guide devices during the installation process, which facilitates the installation of the concrete frame column 1 and improves the installation efficiency. Correspondingly, a pair of guide steel bars 6 are provided on the building foundation 2. The pair of guide steel bars 6 correspond to the pair of guide sleeves 5, and the pair of guide sleeves 5 are embedded in both sides of the concrete frame column 1. In the specific implementation process, during the hoisting of the precast concrete frame column 1, the connecting steel bars 3 of the concrete frame correspond to the building foundation 2, and the guide sleeve 5 corresponds to the guide steel bars 6. The length of the guide steel bars 6 is longer than the length of the connecting steel bars 3. The diameter of the guide steel bars 6 gradually increases from top to bottom, and the diameter of the guide sleeve 5 gradually increases from top to bottom and matches the diameter of the guide steel bars 6. Through the gradual thickening of the guide steel bars 6, the guide steel bars 6 and the guide sleeve 5 are gradually coaxial when below the guide steel bars 6, thereby realizing the gradual positioning of the concrete frame, ensuring that the concrete frame is lowered more smoothly and stably, and ensuring that the concrete frame is stably placed on the building foundation 2. This ensures the correspondence between the connecting steel bars 3 and the connecting sleeve 4.

[0018] As a preferred option, the top of the connecting steel bar 3 is provided with a guide bevel, and the bottom opening of the connecting sleeve 4 is provided with a guide bevel of the inner diameter, which serves as a guide and avoids collisions.

[0019] As a preferred option, a grouting port 7 extends from one side of the connecting sleeve 4, penetrating one side wall of the concrete frame column 1. An overflow port 8 is also provided at the top of the connecting sleeve 4. A grouting pump is connected through the grouting port 7 to inject cement mortar into the connecting sleeve 4, thereby connecting the connecting sleeve 4 and the connecting steel bar 3 through cement mortar. After the grouting is full, excess mortar will overflow from the overflow port 8 for easy observation.

[0020] As a preferred option, the top of the guide steel bar 6 is a hemispherical structure.

[0021] As a preferred option, the diameter of the guide steel bar 6 is further enhanced by a tapered structure at the transition point.

[0022] In summary, the prefabricated concrete frame column 1 steel reinforcement sleeve, in addition to the connecting steel bars 3 and connecting sleeves 4 used for connection, has a pair of guide sleeves 5 set on both sides of the prefabricated concrete frame column 1, and a pair of guide steel bars 6 set on the building foundation 2. During installation, the guide steel bars 6 gradually thicken and the guide sleeves 5 gradually narrow, achieving a smoother guiding effect, thereby completing the fixed installation of the concrete frame.
