In order to ensure that the positioning accuracy requirements of the three-dimensional coordinates of the steel structure are met, the steel structure measurement and positioning must meet the specification requirements. The value of the precision control will directly affect the overall quality of the steel structure welding construction, often causing the welding seam to be misaligned or the slope not meeting the design requirements. A new method is needed to control the steel structure construction parameters to meet the design requirements, while achieving convenient steel structure measurement and positioning, and easy operation and application.

[0003] The total station leveling method in the prior art uses a total station to respectively stake out the coordinates of both sides of the steel member to be installed and butted, and adjusts the position of the member by the coordinate position until the design coordinate is reached.

[0004] Disadvantages of existing technology:

[0005] (1) Some construction sites are not conducive to the installation and measurement of total stations. Complex steel structures will affect the line of sight of the total station, which is not conducive to the control of measurement accuracy.

[0006] (2) The total station needs to be reversed many times, which wastes construction time and is not conducive to the overall construction progress. Utility Model Content

[0009] Specifically, the level adjustment device includes a stud passing through the support, the stud is further provided with an ear plate located inside the support, and the stud is symmetrically provided with nuts located outside the support.

[0010] Specifically, one side of the support has at least two studs.

[0011] Furthermore, an anti-slip strip is provided on the ear plate, and the anti-slip strip is used to abut against the steel structure.

[0012] Specifically, the fixing device comprises a fixing rod installed on a support, a measuring instrument fixing bolt is arranged in the middle of the fixing rod, and the fixing rod and the support are connected by the measuring instrument adjusting bolt.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , the utility model provides the following technical solutions: This patent belongs to the field of steel structure construction technology, and realizes the purpose of high-altitude three-dimensional space measurement and positioning, rapid installation of measuring instruments and instrument station change; it is mainly composed of a support, a fixing bolt, and a horizontal adjustable bolt. The device is made of 16mm steel plate. The support is fixed and horizontally adjusted by a horizontal adjustable bolt through a steel structure round tube with an ear plate.

[0023] Specific implementation method (working principle):

[0024] 1. First, two independent devices are connected to form a support 2 through a steel structure round tube with ear plates;

[0025] 2. Use the adjustable bolts on both sides of the support 2 to roughly adjust the horizontality of the support. Before the rough adjustment, put the ear plate first, then the stud 42 passes through the support and the ear plate, and the ear plate and the stud can be welded together. Next, when making the rough adjustment, turn the horizontal adjustable fixing bolt 43 up and down to change the position of the ear plate, and finally achieve the purpose of rough adjustment;

[0026] 3. The measuring instrument is connected to the horizontal steel plate of the support to form a measuring auxiliary device;

[0027] 4. After the instrument is installed, use the adjustable bolts to fine-tune the level of the instrument.

[0028] 5. After fine-tuning is completed, measurement work can be carried out.

[0029] The key points of this utility model are as follows:

[0030] 1. When welding and installing the steel structure connecting ear plates on both sides of the round tube, it is necessary to ensure their horizontality and ensure that the two connecting ear plates are at the same elevation, so as to minimize the adjustment amount of the adjustable bolts.

[0031] 2. This device uses the principle of relative position in space, so the arrangement of the relative coordinate system in space becomes the key point.
