Description

Technical Field

[0001] The utility model relates to the technical field of concrete beams, in particular to a prefabricated concrete beam. Background Art

[0002] A prefabricated concrete structure refers to a concrete structure assembled by precast concrete components or parts through various reliable connection methods.

[0003] At present, precast concrete beams are mostly used to replace cast-in-situ concrete beams in prefabricated buildings. However, when existing precast concrete beams are connected to other components, they generally cannot be directly connected into one body and need to be connected by sleeve grouting. The connection reliability is poor, the connection difficulty is large, and the construction efficiency is low. Therefore, a prefabricated concrete beam is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model proposes a prefabricated concrete beam, which can be quickly assembled by the cooperation of a connecting column and an assembly column with high-strength bolts, and can improve the assembly efficiency of the cross beam.

[0005] The technical solution to achieve the purpose of the utility model is: a prefabricated concrete beam, including a first cross beam and a second cross beam. One end of the first cross beam is fixedly connected with a connecting column, one end of the connecting column is fixedly connected with a reinforcing plate, and an assembly groove is opened at one end of the connecting column. One end of the second cross beam is provided with an assembly column, and the surface of the assembly column is slidably and detachably connected with the inner wall of the assembly groove. The surface of the assembly column is fixedly connected with an adapter plate. A plurality of waist-shaped holes are respectively opened on one side of the reinforcing plate and the adapter plate. The connecting column and the assembly column are locked and connected by high-strength bolts I arranged on the inner walls of the plurality of waist-shaped holes.

[0006] In some embodiments, a plurality of positioning rods are fixedly connected to one end of the first cross beam, and a plurality of sleeves are fixedly connected to one end of the second cross beam. The inner walls of the plurality of sleeves are respectively slidably connected with the surfaces of the corresponding plurality of positioning rods.

[0007] In some embodiments, two slots are opened at one end of the second cross beam, and plug plates are fixedly connected to the inner walls of the two slots by high-strength bolts III.

[0008] In some embodiments, the inner walls of the two plug plates are fixedly connected to the assembly column by high-strength bolts II.

[0009] In some embodiments, a plurality of high-strength bolts II and high-strength bolts III are provided and are linearly distributed.

[0010] Compared with the prior art, the utility model has the following remarkable advantages:

[0011] First: The preliminary positioning can be achieved by the positioning rod and the sleeve provided in the utility model. After the positioning rod is inserted into the sleeve, the assembly grooves on the assembly column and the connection column correspond to each other. Move the first cross beam and the second cross beam in the opposite direction until the connection column is completely inserted into the assembly groove to complete the assembly. The assembly and fixation between the first cross beam and the second cross beam can be realized by the waist-shaped holes opened on the reinforcement plate and the adapter plate in cooperation with the first high-strength bolt, improving the assembly effect of the concrete beam.

[0012] Second: By providing the second high-strength bolt, the third high-strength bolt and two insertion plates, the utility model can avoid forming a rigid connection to the assembly column, thereby improving the assembly effect between the first cross beam and the second cross beam.

[0013] When the existing precast concrete beam is connected to other components, it generally cannot be directly connected into a whole, and sleeve grouting needs to be used for connection, which has poor connection reliability, great connection difficulty and low construction efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides an assembled concrete beam by improvement. The technical solution of the present utility model is:

[0022] As shown Figures 1 - 3 in the figure, a prefabricable concrete beam includes a first cross beam 1 and a second cross beam 2. One end of the first cross beam 1 is fixedly connected with a connecting column 3. One end of the connecting column 3 is fixedly connected with a reinforcing plate 4. An assembly groove 8 is opened at one end of the connecting column 3. One end of the second cross beam 2 is provided with an assembly column 10. The assembly column 10 is adapted to the inner wall of the assembly groove 8. The surface of the assembly column 10 is slidably and detachably connected with the inner wall of the assembly groove 8.
