[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figures 1 to 4A prefabricated formwork column installation and construction structure includes a base 1, a plurality of steel bars 2 are fixedly connected to the base 1, a threaded groove 3 is opened on the surface of the steel bar 2, and a prefabricated formwork column body 4 matching it is threadedly connected to the threaded groove 3, and a threaded rod 5 matching the steel bar 2 is provided at the lower end of the prefabricated formwork column body 4, and an internal threaded tube 6 is threadedly connected to the threaded rod 5. Four groups of auxiliary positioning mechanisms 7 are provided on the base 1, and each group of auxiliary positioning mechanisms 7 consists of two identical parts.

[0021] like Figures 1 to 4 As shown, the prefabricated formwork column installation construction structure in the present invention, when in use, first place the auxiliary positioning mechanism 7 on the inner side of the steel bar 2 in sequence, so that the first groove 702 on the bottom plate 701 is in contact with the surface of the steel bar 2, at this time, the lower surface of the support plate 704 is higher than the upper end of the steel bar 2, and then place the second auxiliary positioning mechanism 7 on the outer side of the steel bar 2 in sequence, so that the two auxiliary positioning mechanisms 7 are fitted together, and the two auxiliary positioning mechanisms 7 are fixed by using bolts 9 and nuts 10 on the fixing block 8, so that the steel bar 2 is firmly fixed in the first groove 702 on the two auxiliary positioning mechanisms 7, and the installation of the auxiliary positioning mechanism 7 is completed, and the prefabricated formwork column body 4 that is lifted up is slowly lowered and its position is adjusted. When the internal threaded tube 6 set at the lower end of the prefabricated formwork column body 4 slides into the trapezoidal rotation cutting groove 705 on the auxiliary positioning mechanism 7, continue to prefabricated formwork column body 4 below, under the action of the trapezoidal rotation cutting groove 705, the internal threaded tube 6 moves downward along the trapezoidal rotation cutting groove 705 and the inner wall of the second groove 706, so as to directly align with the steel bar 2 and resist against the steel bar 2. At this time, the alignment of the internal threaded tube 6 and the steel bar 2 can be completed. Rotate the internal threaded tube 6 to thread the internal threaded tube 6 and the threaded groove 3 on the steel bar 2, thereby fixing the prefabricated formwork column body 4 on the steel bar 2. According to the opposite operation of the above, remove the bolts 9 and nuts 10, and the auxiliary positioning mechanism 7 can be removed for continued use in subsequent work.

[0022] like Figure 4 As shown, both sides of the auxiliary positioning mechanism 7 are fixedly connected with a fixing block 8 with a round hole in the middle, and the two auxiliary positioning mechanisms 7 are fixed to both sides of the steel bar 2 by bolts 9 and nuts 10.

[0023] Specifically, the two auxiliary positioning mechanisms 7 are fixed by bolts 9 and nuts 10, so as to facilitate the removal of the auxiliary positioning mechanisms 7 after the prefabricated formwork column body 4 and the steel bars 2 are fixed.

[0024] like Figure 2 or Figure 3As shown, the auxiliary positioning mechanism 7 includes a base plate 701, a first groove 702 is provided on the base plate 701, a support rod 703 is fixedly connected to the upper end of the base plate 701, the upper end of the support rod 703 is fixedly connected to the support plate 704, a trapezoidal rotation cutting groove 705 is provided on the surface of the support plate 704, and a second groove 706 is provided on the lower surface of the support plate 704, and the trapezoidal rotation cutting groove 705 is connected to the second groove 706.

[0025] Specifically, the auxiliary positioning mechanism 7 is first placed on the inner side of the steel bar 2 in sequence, so that the first groove 702 on the bottom plate 701 is in contact with the surface of the steel bar 2. At this time, the lower surface of the support plate 704 is higher than the upper end of the steel bar 2. Then the second auxiliary positioning mechanism 7 is placed on the outer side of the steel bar 2 in sequence, so that the two auxiliary positioning mechanisms 7 are fitted together. The two auxiliary positioning mechanisms 7 are fixed by using bolts 9 and nuts 10 on the fixing block 8, so that the steel bar 2 is firmly fixed in the first groove 702 on the two auxiliary positioning mechanisms 7, and the installation of the auxiliary positioning mechanism 7 is completed.

[0026] like Figure 3 As shown, the cross section of the first groove 702 is semicircular. When the two first grooves 702 are combined, a full circle is formed. The cross section of the full circle is the same as the cross section of the steel bar 2.

[0027] Specifically, the two first grooves 702 wrap the steel bar 2 so as to fix the auxiliary positioning mechanism 7 through the steel bar 2 .

[0028] like Figure 3 As shown, the cross section of the second groove 706 is semicircular, and the cross section of the two second grooves 706 combined is a full circle, which is slightly larger than the cross section of the internal threaded tube 6 .

[0029] Specifically, this is to allow the internal threaded tube 6 to slide downward along the inner wall of the trapezoidal rotary cutout groove 705 during the downward movement, until it passes through the lower end of the second groove 706 and abuts against the steel bar 2.

[0030] like Figure 3 As shown, the cross-sectional centers of the first groove 702 , the second groove 706 and the trapezoidal rotation cutout groove 705 are in the same vertical direction.

[0031] Specifically, the cross-sectional centers of the first groove 702, the second groove 706 and the trapezoidal rotation cutting groove 705 are in the same vertical direction to ensure that the internal threaded tube 6 is aligned with the steel bar 2 after moving downward, so that the internal threaded tube 6 can be threadedly connected to the thread groove 3 on the steel bar 2.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
