[0033] The fixing plate 4 is used to fix the interception device. The surface of the interception device is sprayed with a release agent, which can be an oil-based release agent or a water-based release agent.

[0034] The top of the fixing plate 4 is provided with a lifting handle 1, which is used to lift the interception device. The lifting handle 1 is located in the middle of the fixing plate 4, so that the interception device can be removed from the concrete after the concrete is poured, and the interception device can be reused. The lifting handle 1 and the fixing plate 4 can be connected by welding or thread.

[0035] The fixed plate 4 is provided with a sliding groove, and a first adjusting handle 2 and a second adjusting handle 3 are slidably connected inside the sliding groove. The length of the sliding groove is greater than or equal to the total length of the distance that the first adjusting handle 2 and the second adjusting handle 3 can slide.

[0036] The baffle assembly 8 is installed at the bottom of the first connecting rod 21 and the second connecting rod 31 to block concrete of different grades. The top of the baffle assembly is connected to the baffle track 6, and the top of the baffle track 6 is connected to the bottom of the first connecting rod 21 and the second connecting rod 31. A long slide rail is provided in the middle of the baffle track 6.

[0037] The bottom of the first adjusting handle 2 is connected to the first connecting rod 21, and the first adjusting handle 2 is used to pull the first connecting rod 21 to slide inside the slide groove. The bottom of the second adjusting handle 3 is connected to the second connecting rod 31, and the second adjusting handle 3 is used to pull the second connecting rod 31 to slide inside the slide groove.

[0038] It should be noted that when the first adjusting handle 2 slides in the slide groove, it drives the first connecting rod 21 to slide outside the slide groove, and when the second adjusting handle 3 slides in the slide groove, it drives the second connecting rod 31 to slide outside the slide groove; the first connecting rod 21 and the second connecting rod 31 slide relative to each other, so that the first connecting rod 21 and the second connecting rod 31 drive the baffle assembly 8 for opening and closing the baffle assembly 8.

[0039] The grid assembly 8 has a reserved opening 9 for inserting the top layer steel bar 7 and the bottom layer steel bar 5. The reserved opening 9 is a through hole with one end open. By inserting the top layer steel bar 7 and the bottom layer steel bar 5 from the construction site into the reserved opening 9 from the open end, the grid assembly forms a grid plane between the top layer steel bar 7 and the bottom layer steel bar 5. The grid plane is used to intercept the pouring of concrete.

[0040] The baffle assembly 8 includes two sets of side baffles 81 and several sets of inner baffles 82 arranged opposite to each other.

[0043] It is worth noting that the first movable plate 810 is connected to a first connecting rod 21. By pulling the first adjusting handle 2, the first movable plate 810 is moved, and the top layer steel bar 7 and the bottom layer steel bar 5 are moved into and out of the reserved opening on the first movable plate 810. This allows the first movable plate 810 and the first fixed plate 811 to form a blocking plane, or to move out through the blocking plate track 6, so that the steel bars can be moved out, making it easier to remove the interception device.

[0044] A set of inner side baffles 82 has a second movable plate 820 and a third movable plate 821. The top ends of the second movable plate 820 and the third movable plate 821 are slidably disposed with the baffle track 6. The top and bottom of the second movable plate 820 are provided with reserved openings 9, and the third movable plate 821 is provided with corresponding reserved openings 9 at the relative positions of the second movable plate 820 and the third movable plate 821.

[0045] The second movable plate 820 and the third movable plate 821 slide relative to each other and form a closed baffle.

[0046] In the baffle assembly, a plurality of the first movable plates 810, the second movable plates 820 and the third movable plates 821 slide toward one end of the baffle track 6, such that all movable plates facing the opposite direction of this sliding are connected to the first connecting rod 21, and all movable plates away from the opposite direction of this sliding are connected to the second connecting rod 31.

[0048] The second connecting rod 31 includes a second support portion 310 and a plurality of second connecting portions 311. The second support portion 310 is connected to the bottom of the second adjusting handle 3, and one end of each second connecting portion 311 is connected to the second support portion 310, and the other end is connected to the baffle assembly that moves relative to the moving direction of the first connecting portion 211.

[0049] The width of the second movable plate 820 and the third movable plate 821 is the width evenly divided between adjacent top-layer steel bars 7 or bottom-layer steel bars 5.

[0050] A method of using a concrete interception device, the method comprising:

[0051] Step 1: Place the interception device; pull the first adjustment handle 2 and the second adjustment handle 3 in opposite directions so that both sets of first movable plates 810 and first fixed plates 811 are in a folded state, and several sets of second movable plates 820 and third movable plates 821 are in a folded state.
