They are embedded in the concrete during the construction process, providing strong fixing force and stability. Nowadays, the installation process of embedded bolts is relatively common in civil and industrial construction.

[0003] Due to the complexity of on-site construction conditions, the installation accuracy of embedded bolts is difficult to control, especially in industrial plant construction, where embedded bolts with larger diameters and heavier weights are often encountered. The accuracy control requirements are relatively high. Inaccurate embedded positioning will make subsequent equipment difficult to install, and in serious cases, it will cause immeasurable consequences. Utility Model Content

Especially in the construction of industrial plants, embedded bolts with relatively large diameters and heavy weights are often encountered, and the accuracy control requirements are relatively high. Inaccurate embedded positioning will make subsequent equipment difficult to install, and serious problems will cause immeasurable consequences.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a pre-buried screw installation precision positioning device, including positive and negative threaded screw rods, a nut is welded in the middle of the surface of the positive and negative threaded screw rods, both ends of the positive and negative threaded screw rods are threadedly connected to A galvanized square tube, and one end of the A galvanized square tube is welded to a positioning sleeve.

[0006] Preferably, a rotating seat A is welded to the front of the positioning sleeve, an internal thread of the rotating seat A is penetrated by a bolt A, and a galvanized square tube B is rotatably connected to the surface of the bolt A.

[0007] Preferably, both ends of the upper surface of the B galvanized square tube are provided with rotation grooves, and a B bolt is inserted into the interior of one of the rotation grooves.

[0008] Preferably, the B galvanized square tube is rotatably connected to a B rotating seat via a B bolt, and a supporting vertical rod is welded to one side of the B rotating seat.

[0012] During use, when pre-embedded screws are carried out in a building, the forward and reverse screws can be rotated by tools such as wrenches, so that the A galvanized square tube is screwed out on both sides, thereby controlling the position of the two positioning sleeves. The personnel can adjust the spacing of the two positioning sleeves according to the installation spacing of the installation equipment, so that the positioning is more accurate, and it can be adjusted on-site according to actual usage conditions, making the equipment more flexible to use and playing a role in precise positioning.
