[0002] In the field of construction, it is often necessary to connect two cross - arranged components together. For example, in the renovation projects of existing buildings that have emerged in recent years, it is often necessary to carry out pile foundation construction inside the retained building. Due to the height and space limitations of indoor construction, it is impossible to bind and hoist a complete steel reinforcement cage into the hole, and it is necessary to adopt the method of on - site fabrication of a flexible steel reinforcement cage for pile foundation construction. Since this flexible steel reinforcement cage is fabricated on - site indoors, the processing efficiency of its connection nodes directly affects the fabrication efficiency of the entire flexible steel reinforcement cage. Moreover, the longitudinal bars use steel strands, and by rotating the steel strands, the height of the flexible steel reinforcement cage can be greatly compressed. Therefore, the longitudinal bars and stirrups need to be rotatably connected.

[0031] The rotating connection base includes a first base 10 and a second base 20. The first base 10 and the second base 20 have the same structure, only the set directions are different. The first base 10 and the second base 20 are rotatably connected back to back. On the opposite sides of the first base 10 and the second base 20, a first arc groove 11 and a second arc groove 21 are respectively provided. As an example, the first base 10 and the second base 20 are connected by a rotating shaft, and the axis of the rotating shaft is perpendicular to the central axis directions of the first arc groove 11 and the second arc groove 21. The first base 10 and the second base 20 can achieve 360° rotation.

[0032] The first buckle member 30 and the second buckle member 40 have the same structure. The first buckle member 30 cooperates with the first base 10 to buckle a first component, and the second buckle member 40 cooperates with the second base 20 to buckle a second component. Third arc grooves 31 and fourth arc grooves 41 are respectively provided on the first buckle member 30 and the second buckle member 40. The first arc groove 11 matches the third arc groove 31 to hoop the first component; the second arc groove 21 matches the fourth arc groove 41 to hoop the second component.

[0033] Combined Figures 1 to 3 As shown, first connection ear plates are provided at both ends of the third arc groove 31 of the first buckle member 30. A pin shaft hole is provided on the connection ear plate at the first end of the third arc groove 31 of the first buckle member 30, and a pin shaft 34 is provided in the pin shaft hole. Second ear plates are provided at both ends of the first arc groove 11 of the first base 10.

[0034] An articulated ear plate 15 is provided on the connection ear plate at the first end of the first arc groove 11 of the first base 10, and the articulated ear plate 15 is articulated with the pin shaft 34. A hot melt adhesive bump 33 is provided on the first connection ear plate 32 at the second end of the third arc groove 31 of the first buckle member 30, and a connection groove 13 is provided on the second connection ear plate 12 at the second end of the first arc groove 11 of the first base 10. The first arc groove 11 matches the third arc groove 31 to buckle the first component. The hot melt adhesive bump 33 on the first connection ear plate 32 matches the connection groove 13 on the second connection ear plate 12, and after the hot melt adhesive bump 33 melts, it can be firmly connected to the connection groove 13. The connection method of the second buckle member 40 and the second base 20 is the same as the connection method of the first buckle member 30 and the first base 10.

[0035] The connecting buckle provided in this embodiment can be fixed to the connecting groove 13 of the first base 10 after heating the hot-melt adhesive bump 33 on the first buckle member 30, thereby buckling the first member. After heating the hot-melt adhesive bump on the second buckle member 40, it can be fixed to the connecting groove of the second base 20, thereby buckling the second member. The first base 10 and the second base 20 are rotatably connected to adapt to the relative rotation between the first member and the second member.

[0036] In a specific embodiment, internal threads 14 are provided in the first arc groove 11, the second arc groove 21, the third arc groove 31, and the fourth arc groove 41 to firmly buckle the first member and the second member.

[0037] In a specific embodiment, the connecting buckle is used for connecting the steel strands and stirrups of a flexible steel cage. The vertical bars of the flexible steel cage are made of steel strands, and the rotation of the steel strands can realize the height change of the flexible steel cage. The first member is the steel strand of the flexible steel cage, and the second member is the stirrup of the flexible steel cage. When the flexible steel cage rotates and compresses, the first base 10 and the second base 20 can rotate relative to each other to adapt to the rotation between the steel strand and the stirrup. During use, the steel strand is located between the first buckle member 30 and the first base 10. After heating the hot-melt adhesive bump 33 on the first buckle member 30, it is fixed to the first base 10. The stirrup is arranged between the second buckle member 40 and the second base 20. After heating the hot-melt adhesive bump on the second buckle member 40, it is fixed to the second base 20.

[0038] In a specific embodiment, a heating sheet is provided inside the hot-melt adhesive bump 33 on the first buckle member 30. Two terminal blocks are arranged on the back of the first connecting plate of the first buckle member 30. The two terminal blocks are respectively connected to both ends of the heating sheet. When the two terminal blocks are respectively connected to the positive and negative poles of the power supply, the heating sheet can be heated, so that the hot-melt adhesive bump 33 melts and is firmly connected to the connecting groove 13 of the first base 10. The heating sheet can be a metal sheet with a preset resistance value.

[0039] In a specific embodiment, connecting ear plates I are provided at both ends of the third arc groove of the first buckle member and both ends of the fourth arc groove of the second buckle member. The connecting ear plates I are provided with hot-melt adhesive bumps. As Figure 4 shown, connecting ear plates II are provided at both ends of the first arc groove of the first base 10' and both ends of the second arc groove of the second base 20'. The connecting ear plates I are adhesively connected to the connecting ear plates II through the hot-melt adhesive bumps, so that the first buckle member is spliced and fixed to the first base, and the second buckle member is spliced and fixed to the second base. Preferably, the connecting ear plates II are provided with connecting grooves matching the hot-melt adhesive bumps. The connecting grooves provide accommodation spaces for the hot-melt adhesive bumps, which can firmly buckle the first buckle member, the first base, and the first member, and then the hot-melt adhesive is adhesively connected to the connecting grooves.
