[0042] The present invention will be described in detail below.

[0043] As Figures 1 - 5 shown:

[0044] On the one hand:

[0045] The present invention provides an auxiliary device for installing and positioning a steel column 100, including a circular ring track 2 arranged horizontally and forming a positioning cavity for the steel column 100, an adjustable support assembly 1 arranged along the circumference of the circular ring track 2 and used for supporting the circular ring support, and multiple groups of positioning components with the same structure and slidably engaged with the circular ring track 2 along the circumference of the circular ring track 2.

[0046] In some possible implementation manners,

[0047] The positioning component includes multiple groups of sliding supports 3 slidably engaged with the circular ring track 2, and steel column 100 positioning members 4 arranged in one-to-one correspondence with the sliding supports 3 and installed on the sliding supports 3.

[0048] Multiple groups of steel column 100 positioning members 4 are arranged on the corresponding sliding supports 3 to support the outer side surface of the steel column 100, effectively support and fix the steel column 100, and can adjust the inclination angle of the steel column 100;

[0049] After the adjustment is in place, the steel column 100 positioning members 4 will effectively support and fix the steel column 100. At this time, by sliding the sliding support 3, the bracket 200 on the steel column 100 can be rotated to a position suitable for the installation of the steel beam; the installation and positioning of the steel column 100 are completed.

[0050] In some possible embodiments,

[0051] A circular chute 21 is provided on the top surface of the circular ring track 2. The sliding support 3 includes a support body 31 slidably mounted in the circular chute 21 and a bolt 32 for fixing the sliding support 3.

[0052] The bolt 32 is used to effectively fix the position of the support body 31 in the circular chute 21.

[0053] In some possible embodiments, in order to effectively prevent the sliding support 3 from sliding out of the circular chute 21;

[0054] The circular chute 21 has an inverted T-shaped structure, and its opening is provided at the small end of the inverted T-shaped structure; the sliding support 3 is installed inside the large end of the inverted T-shaped structure and has a clearance fit with its two inner side surfaces along the circumferential direction of the circular ring track 2.

[0055] Preferably, angle graduation lines are provided on the circular ring track 2; this can make it more convenient for the sliding support 3 to adjust the angle according to the angle adjustment requirements; making the adjustment of the sliding support 3 more convenient.

[0056] In some possible embodiments,

[0057] A long hole 22 is provided along the circumferential direction on the outer side of the circular ring track 2. The long hole 22 communicates with the circular chute 21. One end of the bolt 32 sequentially passes through the long hole 22, the sliding support 3 and abuts against the inner side surface of the circular chute 21.

[0058] A threaded through hole for one end of the bolt 32 to pass through is provided on the support body 31. When fixing the sliding support 3, the screw rod of the bolt 32 will pass through the long hole 22, the support body 31 and abut against the inner side surface of the circular chute 21. At this time, the side of the nut of the bolt 32 close to the circular ring track 2 abuts against the outer side surface of the circular ring track 2; this enables the fixing of the sliding support 3;

[0059] When the steel column 100 rotates, the end of the screw rod in the bolt 32 will not abut against the inner side surface of the circular chute 21, and the inner side surface of the nut will not abut against the outer side surface of the circular ring track 2; the sliding support 3 will be able to slide along the circular chute 21 to realize the rotation of the steel column 100 and adjust the position of the bracket 200 on the steel column 100.

[0060] In some possible embodiments,

[0061] The steel column 100 positioning member 4 includes a support plate 42 that is vertically arranged and installed on the support body 31, and a long screw rod 41 that is screwed to the support plate 42 and is horizontally arranged. One end of the long screw rod 41 passes through the support plate 42 and abuts against the outer side surface of the steel column 100; a rubber pad 43 is arranged at one end of the long screw rod 41 close to the steel column 100.

[0062] The support plate 42 is vertically arranged, and one end of the long screw rod 41 passes through the support plate 42 and abuts against the outer side surface of the steel column 100; this effectively ensures the positioning of the steel column 100. During the installation process, due to uneven base surfaces and other situations, the steel column 100 will tilt. At this time, adjust one or more of the long screw rods 41 so that the long screw rods 41 move closer to the steel column 100 side, thereby making the axis of the steel column 100 vertically arranged and adjusting its tilt angle. After the adjustment is completed, all the long screw rods 41 will abut against the outer side surface of the steel column 100, effectively positioning the steel column 100 in the X-axis direction and Y-axis direction, and ensuring that its coordinates in the X-axis direction and Y-axis direction meet the design requirements.

[0063] In some possible implementation manners,

[0064] There are four groups of the sliding supports 3, which are evenly arranged along the circumferential direction of the circular ring track 2; they are correspondingly arranged with the four groups of steel column 100 positioning components one by one, realizing the stable support and fixation of the steel column 100, and avoiding situations such as tilting due to uneven force.

[0065] In some possible implementation manners,

[0066] The circular ring track 2 includes four groups of arc tracks 20 with the same structure and connected in sequence; the sliding supports 3 are correspondingly arranged with the arc tracks 20 one by one.

[0067] The four groups of arc tracks 20 are correspondingly arranged with the adjustable support assemblies 1 one by one, respectively supporting the four groups of arc tracks 20 and making the four groups of arc tracks 20 on the same horizontal plane. The four groups of arc tracks 20 are located outside the steel column 100 and are connected in sequence to form a circular ring track 2 coaxial with the steel column 100; the steel column 100 positioning components slidably installed on the four groups of arc tracks 20 through the sliding supports 3 will be evenly arranged on the formed circular ring, supporting the steel column 100 and making the force on the steel column 100 more uniform.

[0068] Preferably, the arc track 20 is connected to the vertical pole through a support bracket 200, so that the arc passage 20 is installed on the top of the vertical pole.

[0069] In some possible implementation manners,

[0070] The adjustable support assemblies 1 are multiple groups. Each adjustable support assembly 1 includes a base, a support screw vertically arranged and installed on the base, a support pad sleeved outside the support screw and screwed with the support screw, and a vertical rod sleeved outside the support screw; a jacking hole for the end of the support screw away from the base to extend into is arranged on the vertical rod, and the diameter of the jacking hole is smaller than the size of the support pad.

[0071] Through the above settings, by screwing the support pad along the length direction (Y-axis direction) of the support screw, the height adjustment of the vertical rod can be effectively realized, so that the position of the circular ring track 2 in the Y-axis direction can be adjusted, and further the position adjustment of the positioning member 4 of the steel column 100 in the Y-axis direction can be realized, so as to meet the positioning support and fixation of steel columns 100 with different lengths; by moving the long lead screw 41 in the X-axis direction, the position adjustment of the steel column 100 in the X-axis direction can be realized;

[0072] In the present invention, since the long lead screw 41 and the support plate 42 are screwed together; this enables the support and positioning of steel columns 100 with different outer diameters, making its application range wider.
