[0002] Prefabricated columns and center beams are two commonly used prefabricated components in construction projects. They play an important role in building structures. Prefabricated columns, as the name suggests, are columns prefabricated in factories or prefabrication yards. Center beams, also known as middle beams or floor beams, are horizontal structural components that connect columns and bear floor loads.

[0003] When connecting the prefabricated column and the center beam, it is usually necessary to set a casting template at the connection point, and then pour concrete slurry to connect the prefabricated column and the center beam into a whole. After the concrete solidifies, the casting template needs to be removed, which is time-consuming and laborious. Therefore, a prefabricated column and center beam connection structure is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a prefabricated column and center beam connection structure, which has the advantages of facilitating the connection between the prefabricated column and the center beam, and solves the problem that when connecting the prefabricated column and the center beam, a casting formwork usually needs to be set at the connection point, and the casting formwork needs to be removed after the concrete solidifies, which is time-consuming and labor-intensive to operate.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a prefabricated column and center beam connection structure, comprising two prefabricated columns, the top ends of the two prefabricated columns on opposite sides of which are fixedly installed with corbels, the corbels are provided with a middle beam, the top ends of the outer peripheral walls of the two prefabricated columns are both sleeved with two steel sleeves, and the steel sleeves are provided with a fixed support mechanism.

[0006] Furthermore, the interior of the prefabricated column is provided with a plurality of longitudinal steel bars, one end of which extends to above the prefabricated column, and the interior of the intermediate beam is provided with transverse steel bars, both ends of which extend respectively to between the plurality of longitudinal steel bars.

[0007] Furthermore, a connecting steel bar having one end extending below the transverse steel bar is fixedly installed on the front side and the rear side of the inner wall of the steel sleeve.

[0008] Furthermore, the fixed support mechanism includes a fixing plate, a mounting plate, a first fixing bolt and a support plate. A fixing plate is fixedly installed on the side of the left steel sleeve opposite to the right steel sleeve and located below the middle beam. A mounting plate is fixedly installed on the side of the left fixing plate opposite to the right fixing plate. The left mounting plate and the right mounting plate are fixedly connected by a first fixing bolt respectively. Mounting blocks are embedded on the side of the two prefabricated columns opposite to each other and located below the corbels. A support plate with one end in contact with the mounting block is fixedly installed on the bottom of the fixing plate, and the bottom end of the support plate is fixedly connected to the support plate by a second fixing bolt.

[0009] Furthermore, a connecting plate is fixedly installed on the side opposite to the steel sleeve on the left and the steel sleeve on the right, and the connecting plate on the left and the connecting plate on the right are fixedly connected by a third fixing bolt respectively.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The prefabricated column and center beam connection structure can complete the docking and positioning of the center beam and the prefabricated column by setting up steel sleeves to clamp the two ends of the center beam between the steel sleeves on both sides; in addition, the steel sleeves wrap the docking point between the center beam and the prefabricated column, and concrete can be directly injected without the need to set up additional casting templates.
