It is also the fulcrum of the formwork and its supporting structure. At this time, when the concrete body 6 is poured inside the casting formwork 1, the through-tie rod body 4 is filled inside the casting concrete body 6. After the concrete body 6 solidifies, the through-tie rod remains inside the concrete body 6. Before pouring the concrete body 6, the two ends of the through-tie rod are in contact with the casting formwork 1 through the connecting groove 10 of the cavity blocking block 5, thereby blocking the casting formwork 1 while also fixing the through-tie rod body 4.

[0020] The cavity plugging block 5 includes a preset steel threaded nut 7, an outer conical plastic sleeve seal 8, a connector 9 and a connecting groove 10, and the outer surface of the preset steel threaded nut 7 is filled with an outer conical plastic sleeve seal 8, and the centers of the preset steel threaded nut 7 and the outer conical plastic sleeve seal 8 are both provided with a connector 9, and the outer conical plastic sleeve seal 8 is provided with a connecting groove 10 on the side away from the preset steel threaded nut 7, a concrete body 6 is provided at the center of the two groups of cavity plugging blocks 5, and the cavity plugging block 5 is cone-shaped as a whole, and the fixed end of the cavity plugging block 5 Located inside the concrete body 6, when the concrete body 6 is poured, the cavity plugging blocks 5 are used to fill the gaps on both sides of the pouring template 1 for inserting the through-pull rod body 4. Therefore, when the concrete body 6 is poured, when the concrete body 6 contacts the cavity plugging blocks 5, the concrete body 6 is restricted by the cavity plugging blocks 5. At this time, the cavity plugging blocks 5 reserved on the outside of the pouring template 1 are used for convenient clamping, thereby facilitating the clamping of the cavity plugging blocks 5. Since the outer conical plastic sleeve seal 8 is in contact with the concrete, when During the rotation, the area where the outer conical plastic sleeve seal 8 contacts the concrete is rotated, so that it is separated from the concrete body 6, thereby completing the peeling of the cavity blocking block 5, so that the wall of the concrete body 6 is located at the cavity where the outer surface of the through-tie rod body 4 is set, so that the through-tie rod body 4 on both sides of the extra concrete body 6 is cut, and the outer conical plastic sleeve seal 8 is a plastic structure. Due to the properties of its colloid structure, when it contacts the concrete body 6, the two are not easy to adhere, so that it can be When the cavity blocking block 5 is separated, it can be more convenient to separate the cavity blocking block 5, and the steel threaded nut is connected to the through-pull rod body 4 through the connecting groove 10, thereby completing the fixation of the through-pull rod body 4, and the steel threaded nut is clamped to the outer conical plastic sleeve head 8 through the connecting head 9, so that the outer conical plastic sleeve head 8 is clamped to the outer conical plastic sleeve head 8, and at the same time, by pulling, it is convenient to separate the steel threaded nut and the outer conical plastic sleeve head 8, so that the two can be disassembled and assembled.

[0021] In summary, the utility model uses a casting template 1 and a cavity blocking block 5, wherein the casting template 1 is fixed by fixing the erecting plate 2, so that a cavity is formed inside the casting template 1, and at this time, one end of the through-rod body 4 is connected to the cavity blocking block 5, and the other end of the through-rod body 4 is not connected to the cavity blocking block 5 and is inserted into the empty grooves on both sides of the casting template 1, so that the cavity blocking block 5 connected to one end of the through-rod body 4 is connected to the casting template 1, thereby completing the blocking of one side of the casting template 1, and the other end of the through-rod body 4 is inserted into the cavity blocking block 5 to fix the through-rod body 4, and is also used to insert one end of the tip area of ​​the cavity blocking block 5 into the interior of the casting template 1, and at this time, the through-rod body 4 is fixed by clamping the fixing plate 3, this When the concrete body 6 is poured into the casting template 1, after the concrete body 6 is completely solidified, the clamping fixing plate 3 and the fixed erecting plate 2 are disassembled, and the outer surface of the outer conical plastic sleeve head 8 of the cavity blocking block 5 is clamped, and then the outer conical plastic sleeve head 8 is rotated. Due to the properties of the outer conical plastic sleeve head 8, the area of ​​the concrete body 6 in contact with the outer conical plastic sleeve head 8 is peeled off during the rotation, so that the preset steel threaded nut 7 inside the outer conical plastic sleeve head 8 is peeled off outward along the through-rod body 4, so that a cavity is formed in the area of ​​the concrete body 6 outside the through-rod. Therefore, when the through-rod body 4 is cut, the through-rod body 4 is made parallel to the concrete body 6.
