[0002] In steel structures, the main function of steel columns is to bear the load of buildings and transfer the load to the foundation. Due to the material characteristics and structural design of steel columns, steel columns can bear greater loads and are more suitable for high-rise buildings than traditional concrete structures. Steel columns can also be used as supports in various structural systems, such as frame structures, truss structures, etc. By reasonably combining steel columns and other components, different structural systems can be formed to bear different loads. Steel columns have the advantages of earthquake resistance, corrosion resistance, stability and reliability, which make them widely used in the fields of industrial buildings, bridges, ships, etc. Therefore, steel columns play an important role in building structures, providing important guarantees for the stability, safety, aesthetics and durability of buildings.

Specific embodiments

[0022] The technical solution of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] As Figure 1 , Figure 2 and Figure 3 , an insertion-type steel column installation and correction device includes a frame body. The frame body includes a "U"-shaped frame. The "U"-shaped frame includes a top bracket 1 and a bottom bracket 2, which are fixedly connected by a second connecting piece 10. The second connecting piece 10 is a square steel pipe. The top bracket 1 and the bottom bracket 2 each include three horizontally arranged members perpendicular to each other in sequence. Third connecting pieces 15 are vertically fixed in the middle of the corresponding horizontal members on the top bracket 1 and the bottom bracket 2. The third connecting piece 15 is a channel steel member. A through hole is provided in the middle of the third connecting piece 15, and a connecting nut 12 is welded at the through hole.

[0024] The correction device further includes a limiting bracket corresponding to each of the three groups of horizontal members. The limiting bracket includes a first horizontal member 5 and a second horizontal member 6 arranged vertically. A first connecting piece 7 is vertically fixed in the middle of the first horizontal member 5 and the second horizontal member 6. The first connecting piece 7 is a square pipe. The inner side surfaces of the first connecting piece 7 are flush with the inner side surfaces of the first horizontal member 5 and the second horizontal member 6, and are used to fit with the surface of the steel column.

[0025] A first sleeve 8 is fixed on the "U"-shaped frame, and a second sleeve 14 slidably connected to the first sleeve 8 is fixed on the limiting bracket. The cooperation between the first sleeve 8 and the second sleeve 14 prevents the limiting bracket from tilting and reduces errors.

[0026] As Figure 4 and Figure 5 , clamping grooves 16 are provided at the open ends of the top bracket 1 and the bottom bracket 2. The frame body further includes a first connecting rod 3 and a second connecting rod 4. The clamping grooves 16 at the two open ends of the top bracket 1 cooperate with the two ends of the first connecting rod 3, and the clamping grooves 16 at the two open ends of the top bracket 2 cooperate with the two ends of the second connecting rod 4; both the first connecting rod 3 and the second connecting rod 4 are formed by welding angle steels, and are used to stabilize the frame body and prevent it from deforming under stress.

[0027] On the inner side of the top bracket 1, a scale 13 is provided for the positioning bracket to position according to the off-axis dimension of the steel column drawing; a spirit level 17 is also installed on the positioning bracket as a reference for leveling; holes for fixing the bracket are opened at the four corners of the bottom bracket 2 for fixing the steel column installation and correction device on the surface of the cup foundation concrete through expansion bolts.

[0028] Such as Figure 6 , the rotating lead screw 9 is rotatably connected to the first connecting member 7 and is matched with the connecting nut 12 on the corresponding side. An adjusting nut 11 is fixed at the outer end of the rotating lead screw 9. By rotating the adjusting nut 11, the relative position between the positioning bracket and the frame body can be adjusted.

[0029] First, fix the steel column installation and correction device. Locate the auxiliary axis on the surface of the cup foundation in advance, mark the installation position according to the installation hole on the bottom bracket of the steel column installation and correction device. First, remove the first connecting rod 3 and the second connecting rod 4 from the "U" - shaped frame, place the steel column installation and correction device on the surface of the cup foundation, align the installation hole with the marked position on the surface of the cup foundation, observe whether the spirit level 17 is centered, finely adjust the steel column installation and correction device, and after the spirit level 17 is centered, fix the steel column installation and correction device through expansion bolts to make the steel column installation and correction device stable.

[0030] Then, adjust the steel column installation and correction device to correct the steel column. After installing the steel column installation and correction device on the cup foundation, according to the off-axis dimension of the steel column drawing, select two mutually perpendicular positioning brackets, respectively rotate the corresponding adjusting nuts 11, push the rotating lead screw 9, so that the positioning bracket moves. During the movement, observe the scale 13 on the top bracket 1, and stop rotating when the position of the positioning bracket coincides with the off-axis dimension of the steel column in the drawing. After the above two positioning brackets are fixed, hoist the steel column. During the hoisting process of the steel column, after the steel column enters the cup, it is close to the above two fixed positioning brackets. Then place the first connecting rod 3 and the second connecting rod 4 in the corresponding card slots 16 on the top bracket 1 and the bottom bracket 2 respectively, ensure that the connecting rod coincides with the card slot 16. After inspection, adjust the adjusting nut 11 on the remaining side through an electric torque wrench, continuously apply force to this positioning bracket through the electric torque wrench, so that the steel column is completely tightly attached to the positioning bracket, thereby playing a role in controlling the verticality and accuracy of the socket - type steel column and achieving the correction effect.

[0031] After the steel column is corrected and installed, use an electric torque wrench to reverse - rotate the adjusting nut 11 to retract the lead screw 9 and the positioning bracket, remove the first connecting rod 3 and the second connecting rod 4, remove the expansion bolts on the surface of the cup foundation, and then remove the steel column installation and correction device.

[0032] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
