[0039] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0040] like Figure 1-4 As shown, an embodiment of the utility model provides a column head connector C, including a connecting male component 1 and a connecting female component 2.

The third vertical plate 211 is provided with second through holes 212 . The two second through holes 212 are respectively located on both sides of the outermost second rib plate 214 . The second through holes 212 are aligned with the first through holes 114 .

[0042] During assembly, the first through hole 114 and the second through hole 212 are aligned so that the bolts can be inserted into the first through hole 114 and the second through hole 212 at the same time, and the first vertical plate 111 and the third vertical plate 211 are fastened together, so that the male connection member 1 and the female connection member 2 are assembled. The first through hole 114 and the second through hole 212 are arranged on the outside of the first rib plate 113 and the second rib plate 214 instead of between the first rib plates 113 or the second rib plates 214, which leaves a larger operating space for the operator and makes it more convenient for the operator to tighten the bolts.

[0043] Furthermore, the height of the second vertical plate 112 is higher than that of the first vertical plate 111 , and the second vertical plate 112 is used to connect the built-in steel bars 3 .

[0044] Preferably, the first base 11 further includes a first bottom plate 115, the first bottom plate 115 is fixed above the first rib plate 113, the first vertical plate 111 and the second vertical plate 112 are respectively arranged on both sides of the first bottom plate 115, wherein the first vertical plate 111 is arranged on one side of the bottom surface of the first bottom plate 115, the second vertical plate 112 is arranged on the other side of the first bottom plate 115, and the upper end of the second vertical plate 112 is higher than the first bottom plate 115.

[0047] Preferably, the male connector 1 further includes a male connector tongue 12, and the female connector further includes a female connector tongue 22. The adjacent edges of the male connector tongue 12 are respectively fixedly connected to the second vertical plate 112 and the first bottom plate 115, and are respectively perpendicular to the second vertical plate 112 and the first bottom plate 115. A third through hole 121 is provided on the male connector tongue 12. The female connector tongue 22 is fixed on the second bottom plate 213, and the projection of the female connector on the second bottom plate 213 is perpendicular to the projection of the third vertical plate 211 on the second bottom plate 213.

During the tightening process, the surfaces of the male connecting tongue 12 and the female connecting tongue 22 gradually come close to each other, so that the first through hole 114 and the second through hole 212 are gradually aligned in the x direction. When the male connecting tongue 12 and the female connecting tongue 22 are fitted together, the first vertical plate 111 and the third vertical plate 211 are reinforced in the y direction. Since the fourth through hole 221 is a waist-shaped hole, the male connecting component 1 and the female connecting component 2 have a certain amount of movable margin in the y direction, which is more convenient for assembly.

[0050] Based on the same inventive concept, the present application also provides a prefabricated structure, referring to Figure 5 ,exist Figure 5In order to better show the connection method between the column head connector C and other steel bars, Figure 5 The frame beam B on the right side is hidden, and the steel bars in the left frame beam B are arranged in the same manner as the steel bars in the right frame beam B. The prefabricated structure includes the aforementioned column head connector C, as well as a frame column A and a frame beam B. An internal steel bar 3 is embedded in the frame column A, and at least one section of the internal steel bar 3 is exposed outside the frame column A.

The use of the first auxiliary steel bar 4 ensures the connection strength between the connecting mother part 2 and the frame beam B to prevent the two from detaching.

[0054] Furthermore, the prefabricated structure further includes a second auxiliary steel bar 5 and a third auxiliary steel bar 6. The second auxiliary steel bar 5 and the first auxiliary steel bar 4 are arranged at the same end of the frame beam B. One end of the second auxiliary steel bar 5 is embedded in the frame beam B, and the other end is exposed. The third auxiliary steel bar 6 is arranged above the frame beam A, and at least one end of the third auxiliary steel bar 6 extends out of the frame column A, and the exposed end of any third auxiliary steel bar 6 is fixedly connected to the exposed end of the second auxiliary steel bar 5.
