[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A column head protection device for a backfill frame column, the structure is as follows Figure 1 As shown, a plurality of unit elements 100 are sequentially connected to form an enclosure structure surrounding the steel bar 200. Figure 1 In the figure, a plurality of unit elements 100 enclose a rectangle, which may be a planned concrete pouring area, or other regular or irregular shapes larger than the pouring area, so as to prevent backfill soil from entering the interior of the steel bars.

[0025] The structure of the unit element 100 is as follows Figure 2 As shown, it includes a rectangular plate 110, a slot 120 and a block 130, and the slot 120 and the block 130 are respectively fixed on the longer sides of the rectangular plate 110. The rectangular plate 110 can be made of a thin iron sheet, the slot 120 can be made of an iron pipe, and the block 130 can be made of an iron block. The slot 120 and the block 130 are welded to the rectangular plate 110. The rectangular plate 110 is mainly used to provide a large area of ​​coverage to prevent backfill soil from entering. The slot 120 and the block 130 are mainly used to connect the unit elements 100 to each other.

[0026] The structure of the card slot 120 is as follows: Figure 3 As shown, it is a hollow cylindrical structure with through holes on the upper and lower surfaces. One side of the slot 120 is welded to the rectangular plate 100, and the other side is provided with an inverted "T"-shaped opening, which includes a horizontal gap 121 and a vertical gap 122; the horizontal gap 121 and the vertical gap 122 are formed by the sidewalls of the slot 120.

[0027] The structure of the block 130 is as follows: Figure 4As shown, it is a "T"-shaped structure, including an integrally formed clamping portion 131 and a connecting portion 132. The connecting portion 132 is welded to one side of the rectangular plate 100, and the other side is integrally formed with the clamping portion. When the clamping block 130 is clamped into the clamping slot 120, the clamping portion 131 is located in the through hole of the clamping slot 120, and the connecting portion 132 can move from the vertical gap 122 to the horizontal gap 121. At the horizontal gap 121, the clamping block 130 can be rotated 90 degrees counterclockwise or 90 degrees clockwise to form a corner connection of the column head protection device. More specifically, the cross-sectional dimension of the engaging portion 131 is larger than the cross-sectional dimension of the connecting portion 132. When connected, the engaging portion 131 is located inside the slot 120, and the side length of the engaging portion 131 in the horizontal plane is smaller than the inner wall diameter of the slot 120, so that the engaging portion 131 can move in the slot 120; when moving vertically, to ensure that the engaging portion 131 does not expose from the vertical gap 122 and the connecting portion 132 can move vertically smoothly, the connecting portion 132 is located in the vertical gap 122, the width of the connecting portion 132 is smaller than the width of the vertical gap 122, and the width of the engaging portion 131 is larger than the width of the vertical gap 122; to ensure that the engaging portion 131 does not expose in the horizontal gap and the connecting portion 132 can rotate smoothly, the height of the horizontal gap 121 is larger than the height of the connecting portion 132 but smaller than the height of the engaging portion 131.

[0028] In the process of connecting multiple unit components, first fix the position of one unit component, then insert the block 130 of another unit component from top to bottom into the slot 120 of the fixed unit component. At this time, the engaging portion 131 is located inside the slot 120 and the connecting portion 132 is located in the vertical gap 122. Slide the block 130 to the horizontal gap 121, and when it reaches the bottom, rotate and adjust it according to the position of the frame column steel bar 200 to ensure that the rectangular plate 110 is close to the steel bar. Finally, connect multiple identical unit components in turn, and adjust the number of units to be used according to the size of the frame column. The final finished product effect diagram is shown in FIG. Figure 1 .
