DETAILED DESCRIPTION

[0020] The technical scheme in the utility model is further explained below in connection with the drawings and embodiment.

[0021] As shown in Figures 1-4 The utility model discloses an assembly type reinforced concrete structure beam column connecting joint, which comprises:

[0022] The prefabricated cross beam 2 is embedded with a plurality of L-shaped reinforcing bars 9, and the prefabricated support column 3 is embedded with a plurality of vertical reinforcing bars 11, which are distributed at both ends of the prefabricated support column 3, and the length of the vertical reinforcing bar 11 at the lower end of the prefabricated support column 3 is greater than that at the upper end, so that when the prefabricated support column 3 is installed at the upper and lower ends of the support block 1, the vertical reinforcing bars 11 in the pouring cavity 10 are close to each other but not in contact.

[0023] The connecting structure comprises a support block 1, which is in the shape of a cube; the support block 1 is internally provided with a pouring cavity 10, and the upper end of the support block 1 is provided with a pouring hole 7 and an overflow hole 8, which are in communication with the pouring cavity 10; the pouring hole 7 is used to pour concrete into the pouring cavity 10, and as the amount of concrete increases, the concrete can finally overflow through the overflow hole 8, indicating that the pouring cavity 10 is filled with concrete.

[0024] Each of the four sides of the support block 1 is provided with a support groove 4 capable of supporting the prefabricated cross beam 2, and the support groove 4 is connected to the pouring cavity 10 through a plurality of strip-shaped connecting tendon grooves 5; the upper and lower ends of the support block 1 are provided with a plurality of circular connecting tendon grooves 6; the L-shaped reinforcing bar 9 cooperates with the strip-shaped connecting tendon groove 5; during installation, the prefabricated cross beam 2 is installed in the support groove 4, and the L-shaped reinforcing bar 9 extends into the pouring cavity 10 through the strip-shaped connecting tendon groove 5; since the support block 1 is hollow and has reduced support strength, the four support grooves 4 and the four prefabricated cross beams 2 can strengthen the support block 1 and improve its support capacity; during installation, the support block 1 is first installed at the upper end of the prefabricated support column 3, and then the prefabricated cross beam 2 is installed.

[0025] After the above installation is completed, the prefabricated support column 3 is installed at the upper end of the support block 1 after the pouring cavity 10 is poured with concrete through the pouring hole 7; at this time, the vertical reinforcing bar 11 on the prefabricated support column 3 cooperates with the circular connecting tendon groove 6, and the upper vertical reinforcing bar 11 cooperates with the L-shaped reinforcing bar 9, that is, the vertical reinforcing bar 11 is located inside the L-shaped reinforcing bar 9 and the two are not in contact; when the L-shaped reinforcing bar 9 is moved outward, the L-shaped reinforcing bar 9 will be in contact with the vertical reinforcing bar 11; in this way, the prefabricated cross beam 2 and the prefabricated support column 3 are assembled, and the subsequent construction is not affected, and the assembly efficiency is reduced, and the subsequent construction needs to wait for the pouring section to solidify, which prolongs the completion period.
