Technical Field
[0001] This utility model relates to the technical field of construction equipment for steel structures in building engineering, and specifically to a precise positioning device applicable to anchor bolts of steel structures of different lengths. Background Technology
[0002] With the rapid development of the national economy, steel structure workshops have also developed rapidly, emerging in large numbers and widely used in large industrial plants, stadiums, aircraft hangars, and other locations, characterized by large spans and heights. To meet the load-bearing requirements of large-span heavy steel structures, steel columns with shear grooves are increasingly used. The installation of these columns requires the installation of anchor bolts. Undoubtedly, the installation accuracy of the anchor bolts directly determines the installation accuracy of the steel column; therefore, positioning devices are typically used. However, existing steel structure anchor bolt positioning devices suffer from cumbersome structures, are time-consuming and labor-intensive to use, and cannot achieve positioning of anchor bolts of different lengths.
[0003] Therefore, there is an urgent need to design a precise positioning device that can be used for anchor bolts of steel structures of different lengths. Utility Model Content

[0006] A precision positioning device for steel structure anchor bolts of different lengths includes an upper positioning plate, a lower positioning plate, a limiting nut, a leveling nut, and a fixed shaft. The bottom end of the fixed shaft is fixedly connected to the lower positioning plate. The upper positioning plate has a first through hole for the fixed shaft to pass through. The limiting nut and the leveling nut are both threaded onto the fixed shaft. The upper positioning plate is located between the limiting nut and the leveling nut. The limiting nut is in close contact with the upper surface of the upper positioning plate, and the leveling nut is in close contact with the lower surface of the upper positioning plate. Both the upper and lower positioning plates have a second through hole for the anchor bolt to pass through.
[0007] Furthermore, both the upper positioning disk and the lower positioning disk are circular ring structures.
[0008] Furthermore, the number of second through holes in both the upper positioning plate and the lower positioning plate is six, and they correspond one-to-one.
[0009] Furthermore, the number of first through holes in the upper positioning plate and the number of first through holes in the lower positioning plate are both six, and they correspond one-to-one.
[0010] Furthermore, both the upper positioning plate and the lower positioning plate are made of steel plate.
[0011] Furthermore, the fixed shaft is a fully threaded screw, and the fixed shaft is welded to the lower positioning plate.
[0012] Furthermore, both the limiting nut and the leveling nut are made of galvanized hexagonal nuts.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The anchor bolts can be positioned using an upper positioning plate, a lower positioning plate, a limit nut, a leveling nut, and a fixed shaft. The overall structure is simple. The upper positioning plate moves along the fixed shaft to achieve the positioning and fixing effect of anchor bolts of different lengths, making it convenient to use. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0022] Combination Figures 1 to 5This embodiment provides a precise positioning device for steel structure anchor bolts of different lengths, including an upper positioning plate 1, a lower positioning plate 2, a limiting nut 3, a leveling nut 4, and a fixed shaft 5. The bottom end of the fixed shaft 5 is fixedly connected to the lower positioning plate 2. The upper positioning plate 1 is provided with a first through hole 6 for the fixed shaft 5 to pass through. The limiting nut 3 and the leveling nut 4 are both threadedly connected to the fixed shaft 5. The upper positioning plate 1 is located between the limiting nut 3 and the leveling nut 4. The limiting nut 3 is in close contact with the upper surface of the upper positioning plate 1, and the leveling nut 4 is in close contact with the lower surface of the upper positioning plate 1. Both the upper positioning plate 1 and the lower positioning plate 2 are provided with a second through hole 7 for the anchor bolt 8 to pass through.
[0023] In use, the upper positioning plate 1 achieves the positioning and fixing effect of anchor bolts of different lengths by moving along the fixed shaft 5. Among them, the limit nut 3 is located above the upper positioning plate to restrict the movement of the upper positioning plate; the leveling nut 4 is located below the upper positioning plate to adjust the level of the upper positioning plate; the lower positioning plate 2 is located at the bottom of the positioning device and is used to connect the fixed shaft and the steel mesh around the anchor bolts; the upper positioning plate 1 is located between the limit nut 3 and the leveling nut 4 to fix the anchor bolts.
[0024] In this embodiment, both the upper positioning plate 1 and the lower positioning plate 2 are annular structures. Both the upper positioning plate 1 and the lower positioning plate 2 are made of steel plate; specifically, the upper positioning plate 1 is made of stainless steel plate, and the lower positioning plate 2 is made of ordinary steel plate.
[0025] Preferably, the upper positioning plate 1 and the lower positioning plate 2 have the same structure, and the top view and side view of the lower positioning plate 2 are the same as those of the upper positioning plate 1. Figures 3-4 Consistent.
[0026] In this embodiment, the number of second through holes 7 in both the upper positioning disk 1 and the lower positioning disk 2 is six, and they correspond one-to-one. The number of first through holes 6 in both the upper positioning disk 1 and the lower positioning disk 2 is six, and they correspond one-to-one.
[0027] In this embodiment, the fixed shaft 5 is a threaded rod with a specification of not less than M8, and the fixed shaft 5 is welded to the lower positioning plate 2.
[0028] In this embodiment, both the limiting nut 3 and the leveling nut 4 are galvanized hexagonal nuts, and their dimensions are matched with the fixed shaft.
[0029] In use, the construction personnel first weld and assemble the lower positioning plate 2 and the fixed shaft 5, then screw the leveling nut 4 into the fixed shaft and keep it horizontal. After the assembly is completed, the lower positioning plate 2, the fixed shaft 5, and the leveling nut 4 are put into the anchor bolts as a whole. Then the upper positioning plate 1 is put into the whole and adjusted to be horizontal. Finally, the limit nut 3 is screwed into the fixed shaft to limit the upper positioning plate 1.
[0030] This solution achieves anchor bolt positioning using an upper positioning plate, a lower positioning plate, a limit nut, a leveling nut, and a fixed shaft. The overall structure is simple. The upper positioning plate, by moving along the fixed shaft, effectively positions and fixes anchor bolts of different lengths, making it convenient to use. Furthermore, the upper positioning plate, leveling nut, and limit nut are reusable, saving resources.
[0031] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
