When installing embedded bolts in the installation base or pile head, welding is required. The traditional construction method is to use a fixed model plate welded to the base steel bar and then bolted. This fixing method is expensive and will also lead to extended construction time. Temporary power supply is also required for welding. In addition, when using electric welding machines for welding in rainy weather, it will be greatly affected, such as affecting the construction progress and work safety. Utility Model Content

[0003] In order to overcome the technical defects of using fixed model plates to be welded into the base steel bars for bolt fixing, which is high in cost, prolongs the construction period, requires temporary electricity access during welding, and is easily affected by the weather and other environmental factors, the utility model provides a fixing device for the installation of embedded bolts in steel structures.

[0004] The utility model provides a fixing device for installing embedded bolts of steel structures, comprising a fixed support plate, four threaded adjustment rods, four support angles and four horizontal adjustment rods. The fixed support plate is provided with a plurality of fixing holes for inserting embedded bolts. The shape of the fixed support plate is adapted to the shape of the top surface of the mounting base and is rectangular. The four corners of the fixed support plate are respectively provided with fixed connection points of the adjustment rod. Each fixed connection point of the adjustment rod is rotatably connected to the upper end of the threaded adjustment rod through a bearing. The threaded connecting rod is located in the vertical direction, and the lower end of the threaded connecting rod is threadedly matched with a threaded fixing sleeve. The supporting angle corresponds to and fits the four top corners of the mounting base. The supporting angle is welded by three mutually perpendicular square baffles, and each square baffle is connected to the other two square baffles; the threaded fixing sleeve is welded to the side wall of the supporting angle; the four horizontal adjustment rods are parallel to the four edges of the fixed support plate, and each horizontal adjustment rod is sleeved with two horizontal sleeves. The two horizontal sleeves on the same horizontal adjustment rod are respectively welded to the side walls of the two supporting angles corresponding to the position of the horizontal adjustment rod; the horizontal sleeve is connected with an adjustment top screw that is tightly fitted with the horizontal adjustment rod.

[0005] The size of the fixed support plate is determined according to the size of the embedded bolts, and the shape of the fixed support plate is determined according to the shape of the mounting base. The present invention provides a solution in which the fixed support plate is rectangular. When in use, the four support angles are clamped onto the four top corners of the mounting base. When the four support angles are completely aligned with the four top corners of the mounting base, that is, the contact area is maximized, the adjustment screws on each horizontal adjustment rod are tightened to fix the position of the support angles and the horizontal adjustment rod. When the position of the support angles is fixed, the position of the threaded fixing sleeve connected to them is also fixed. The threaded adjustment rod is rotated according to the size and dimensions of the mounting base. One end of the threaded adjustment rod is connected to the fixed support plate through a bearing, and the other end can move up and down in the threaded fixing sleeve, thereby achieving the up and down adjustment of the threaded adjustment rod. The threaded adjustment rod is rotated to keep the fixed support plate horizontal, and the entire device is fixed and formed. After the entire device is fixed, the embedded bolts are inserted into the fixed holes of the fixed support plate to facilitate concrete pouring, and the embedded bolts will not be displaced during the pouring process.
