The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] The different grade concrete isolation device for the beam-column joint comprises a positioning seat and a plurality of separation components.

[0027] The positioning seat is detachably connected to the upper side of the binding steel bars at the beam-column node 300, and the positioning seat includes an upper metal plate 110 and a bracket 120. The upper metal plate 110 is fixedly connected to the bracket 120, and the bracket 120 is detachably connected to the upper side of the binding steel bars at the beam-column node 300 through a steel wire. The upper end surface of the upper metal plate 110 has an inclination angle relative to the horizontal plane, and the upper end surface of the upper metal plate 110 has an inclination angle of 45° relative to the horizontal plane. A waist-shaped hole 111 is opened on the upper metal plate 110, and the length direction of the waist-shaped hole 111 is consistent with the separation direction along the beam-column node 300.

[0028] The positioning seat is detachably connected to the upper side of the tied steel bar, which is easy to install and can adjust the position and angle according to actual needs to adapt to beam-column nodes 300 of different specifications. The upper end surface of the upper metal plate 110 has an inclination relative to the horizontal plane, which can make the concrete separate naturally during the pouring process and effectively prevent the mixing of concrete of different grades.

[0029] The partition assembly includes a partition rod 210 and two partition nuts 220. The partition rod 210 (the main material of the partition rod 210 is Ф12 round steel, which can be obtained locally, which not only achieves waste utilization, but also solves the actual problem on site) passes through the positioning seat and extends into the binding steel bars at the beam-column node 300. The partition rod 210 passes through the waist-shaped hole 111 of the upper metal plate 110 and is matched by two partition nuts 220. The axial direction of the partition rod 210 is consistent with the normal direction of the upper end surface of the positioning seat. The partition rods 210 of multiple groups of partition assemblies are arranged in sequence along the partition position at the beam-column node 300.

[0030] The upper side wall of the partition rod 210 is provided with threads, and two partition nuts 220 are mounted on the partition rod 210, and the two partition nuts 220 are respectively located at the upper and lower sides of the positioning seat. The lower end of the partition rod 210 penetrates the positioning seat and extends into the binding steel bar, which enhances the stability and firmness of the device and ensures that no displacement occurs during the concrete pouring process. The axial direction of the partition rod 210 is consistent with the normal direction of the upper end face of the positioning seat, ensuring that the concrete flows along the axial direction of the partition rod 210 during pouring, further improving the isolation effect.

[0031] Furthermore, a plurality of groups of partition rods 210 are sequentially arranged along the partition positions at the beam-column joints 300 , and a plurality of partition areas can be provided according to actual needs to achieve simultaneous pouring of concrete of various grades.

[0032] In addition, considering the need to avoid the upper row of steel bars and other steel bars such as the stirrups of the beam, the number and position of the round steel bars inserted into the beam are set to be able to slide left and right, that is, an elliptical groove is left on the metal plate, and the top of the round steel placed in the groove is threaded, which can also achieve reliable connection and fixation with the upper metal plate 110 through nuts and gaskets.

[0033] The above is only one embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as belonging to the protection scope of the present invention.
