[0036] The steel mesh includes four main steel bars arranged in two rows and two columns. The baffle frame is provided with two steel bar empty slots. The two columns of main steel bars are respectively embedded in the two steel bar empty slots. Two baffle plates respectively close the two steel bar empty slots.

[0038] like Figures 13 to 15 The barrier frame includes a first barrier body 1A, a second barrier body 1B and a middle partition plate 30. The first barrier body and the second barrier body are respectively provided with a steel bar slot 11. The first barrier body is provided with a guide hole 14.

The middle partition plate closes the gap 16 between the first barrier body and the second barrier body.

[0039] The middle partition is provided with a middle partition bolt 31 , which passes through the gap 16 between the first partition body and the second partition body. The middle partition bolt presses the middle partition onto the first partition body and the second partition body through the middle partition pressure plate 32 .

[0040] The middle partition is provided with a screw hole 33, and the middle partition bolt is a stud, and one end of the middle partition bolt is screwed into the screw hole of the middle partition.

[0041] Embodiment 1:

[0042] like Figure 1In construction projects, most high-rise wall columns 41 and beams 42 are usually designed with concrete of different strength grades. It is necessary to isolate the construction boundaries of different strength grades during concrete pouring construction, such as Figure 1 Point C in the figure. This embodiment provides a technical solution for a concrete pouring barrier tool.

[0043] like Figures 2 to 4 A concrete pouring barrier tool comprises a barrier frame 10 and a barrier plate 20.

[0044] The concrete pouring barrier tool of this embodiment is used for a steel mesh with four main steel bars 43 arranged in two rows and two columns.

[0045] The baffle frame 10 is a frame made of square steel pipes. The width W of the baffle frame corresponds to the width W2 of the beam template 44. There are four vertical square steel pipes 17. A steel bar slot 11 is formed between every two vertical square steel pipes, forming two steel bar slots in total. The positions of the two steel bar slots correspond to the positions of the two rows of main steel bars. The width K of the steel bar slot is slightly larger than the diameter of the main steel bar. The lower end of the steel bar slot is open to insert the steel mesh. The two square steel pipes on the inner side of the baffle frame are provided with baffle mounting holes 12, which are through holes. An intermediate baffle 19 is provided between the two square steel pipes on the inner side of the baffle frame.

[0046] The baffle plate 20 is a steel plate, and the length L1 of the baffle plate corresponds to the gap L between the upper and lower main steel bars of each column. The width W1 of the baffle plate is greater than the width K of the steel bar slot. The baffle plate is provided with two upper and lower long holes 22, and the positions of the two long holes 22 correspond to the baffle plate mounting holes 12 of the baffle frame. The baffle plate is provided with a handle 21.

[0047] Two mounting bolts 13 are arranged to pass through the slotted hole 22 of the baffle plate and the baffle plate mounting hole 12, and the baffle plate is mounted on the baffle frame by nuts 18. The baffle plate can be laterally moved along the slotted hole 22 on the baffle frame.

[0048] Before use, the two baffles are moved horizontally to the middle of the baffle frame, leaving the steel bar slot 11 of the baffle frame empty. In this embodiment, due to the width limitation of the baffle frame, the middle of the baffle frame cannot accommodate two baffles at the same time, and the two baffles are respectively arranged on two sides of the baffle frame.

[0049] When using, Figure 5 As shown, the baffle frame is inserted into the steel mesh from above, and the two rows of main steel bars are respectively embedded in a steel bar slot 11, and the lower end of the baffle frame is inserted into the bottom of the beam template 44, as shown in FIG. Figure 6 shown.

[0050] Then move the baffle plate horizontally, and the baffle plate enters the steel bar slot horizontally from the middle of the baffle frame, so that the baffle plate closes the steel bar slot 11 between the upper and lower main steel bars, and then tighten the nut 18 and install the bolts to fix the baffle plate on the baffle frame. Figure 7 shown.

[0051] After the installation of the blocking tool, the shear wall concrete pouring (i.e., pouring high-strength concrete) can be carried out. The blocking tool blocks the concrete at the construction boundary. After the concrete is initially set, the blocking tool is pulled out and the beam and slab concrete pouring (i.e., low-strength concrete) continues.

[0052] In this embodiment, the bolt caps of the four mounting bolts 13 face toward the end of the poured high-strength concrete to prevent the nuts 18 from being buried in the concrete.

[0053] Embodiment 2:

[0054] like Figures 8 to 9 , a concrete pouring barrier tool. This embodiment is an improvement of the first embodiment.

[0055] This embodiment improves the structure of the baffle plate, and the baffle plate is provided with a connecting bolt 23. The baffle plate 20 is provided with a screw hole 25, and the connecting bolt is a stud, and one end of the connecting bolt is screwed into the screw hole of the baffle plate. The baffle plate is also provided with two upper and lower positioning blocks 26, and the width K1 of the positioning block corresponds to the width K of the steel bar slot. The baffle plate and the baffle frame are separate structures, and the connecting bolt fixes the baffle plate to the baffle frame through the connecting pressure plate 24.

[0056] When in use, insert the baffle frame into the steel mesh (the baffle frame does not carry the baffle plate). Fig.10 shown.

[0057] Then, the baffle plate 20 is placed in the steel mesh, with the baffle plate facing the side of the high-strength concrete. The positioning block 26 of the baffle plate is embedded in the steel bar slot of the baffle frame to keep the baffle plate in the proper position in the baffle frame. The connecting bolts 23 of the baffle plate pass through the steel bar slot, and the nuts 18 are tightened. The connecting bolts are connected to the baffle frame through the connecting pressure plate 24, as shown in FIG. Fig.11 , Fig.12 shown.

[0058] After the concrete construction is completed, the nut 18 is removed, and the baffle frame and the baffle plate can be separated, which is very convenient for disassembly of the baffle steel bars.

[0059] The structure of the barrier tool is simplified in this embodiment. The barrier plate and the barrier frame are separated structures. The barrier frame does not need to carry the barrier plate when inserting the steel mesh, making the barrier frame lighter and more convenient to insert into the steel mesh. The connecting bolt 23 is a stud, which is more convenient to store when the barrier tool is in use. In addition, when disassembling the barrier tool, if the nut 18 is screwed due to adhesion to concrete or rust, the stud can be screwed out at one end of the barrier plate, which can ensure the smooth progress of the construction operation.

[0060] Embodiment three:

[0061] A concrete pouring barrier tool. This embodiment is an improvement of the second embodiment.

[0062] like Figures 13 to 15 In this embodiment, the baffle frame includes a first baffle body 1A, a second baffle body 1B and a middle baffle plate 30, and the first baffle body, the second baffle body and the middle baffle plate are separate structures.

[0063] The first partition body and the second partition body are respectively provided with a steel bar hollow groove 11, the first partition body is provided with a guide hole 14, and the second partition body is provided with a guide shaft 15 that slides with the guide hole of the first partition body. The guide hole 14 provided on the first partition body is a square hole, and the guide shaft 15 of the second partition body is a square shaft corresponding to the guide hole 14. The guide shaft of the second partition body is inserted into the guide hole provided in the first partition body, so that the partition frame can adjust the width size.

[0064] The middle partition plate is used to close the gap 16 between the first partition body and the second partition body.

[0065] The middle partition is provided with a middle partition bolt 31, and the middle partition is provided with a screw hole 33. The middle partition bolt is a stud, and one end of the middle partition bolt is screwed into the screw hole of the middle partition.

[0066] The middle partition is provided with a handle 34 for easy operation.

[0067] The middle partition bolts pass through the gap 16 between the first partition body and the second partition body, and the middle partition bolts press the middle partition onto the first partition body and the second partition body through the middle partition pressure plate 32, and also fix the first partition body and the second partition body into an integrated structure.

[0068] The structure of this embodiment can realize the size adjustment function of the partition frame, and can be applied to beam formwork structures of more structural sizes (if necessary, middle partitions of different widths can be configured), or can be applied to construction conditions where there are large size errors in the steel mesh.

[0069] The operation of inserting the first barrier body and the second barrier body into the steel mesh is also more convenient. The barrier tool is also more convenient to store.
