Embodiment 1

[0028] Such as Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, based on the method of splicing steel columns on the construction site, it includes the following steps: divide the steel columns with the same cross-sectional size into several sections, and each section of the steel column is welded with several upper ear plates 1 and several A lower ear plate 5, and the upper ear plate is arranged above the lower ear plate, the center line of the upper ear plate 1 is parallel to the center line of the lower ear plate, and the upper ear plate and the lower ear plate are welded on the outer wall of each steel column They are respectively arranged at the same height, and each lower ear plate and upper ear plate in the same section of steel column are respectively staggered in the vertical direction, the upper ear plate is provided with a through hole 7, and the through hole 7 is connected with the upper ear plate 1 ...

Embodiment 2

[0030] Such as Figure 10 , Figure 11 As shown, when splicing the cross-section column at the construction site and the splicing and installation of the ear plate, the upper steel column 3 is lifted by a crane directly above the lower steel column 4, and the upper steel column 3 and the lower steel column 4 are rotated The angle between each upper ear plate 1 welded on the outer wall of the upper steel column 3 and the corresponding upper ear plate 1 on the outer wall of the lower steel column 4 are aligned in the vertical direction, and the upper steel column 3 Lower the height until the bottom of the upper steel column 3 contacts the top of the lower steel column 4, then weld the contacted end faces, and use high-strength bolts to connect the lower ear plate 5 on the upper steel column 3 to the lower steel column. The upper ear plate 1 on the column 4 close to the lower ear plate 5 is connected as a whole structure, and the steel column is hoisted repeatedly, so that each ...

Embodiment 3

[0032] Such as Figure 12 , 13 , 14, when splicing the box-shaped column at the construction site and the splicing and installation of the lug plate, use a crane to lift another section of the steel frame column directly above the lower steel frame column 4, and rotate the upper steel frame column 3 and the lower steel frame column The angle between the columns 4 is such that each upper ear plate 1 welded on the outer wall of the upper steel column 3 and the corresponding upper ear plate 1 on the wall of the lower steel column 4 are aligned in the vertical direction, and the upper steel column The height of the bone column 3 is lowered until the bottom of the upper steel bone column 3 contacts the top of the lower steel bone column 4, and then the contacted end faces are welded, and the lower lug plate on the upper steel bone column 3 and the lower steel plate are connected by high-strength bolts. The upper ear plate 1 close to the lower ear plate 5 on the bone column 4 is co...

Abstract

The invention discloses a method based on implementation of splicing of a steel reinforced column on a construction site. The steel reinforced column having the same cross sectional dimension is divided into a plurality of sections, upper lug plates and lower lug plates are welded to the steel reinforced column and are staggered respectively in the vertical direction, a through hole is formed in each upper lug plate and communicated with the corresponding upper lug plate, an inclined edge is communicated with each through hole, and the distance between each inclined edge and the steel reinforced column is smaller than or equal to 2 mm. A lower steel reinforced column section is hoisted to be fixed to the ground. An upper steel reinforced column section is hoisted, and the angle between the upper steel reinforced column section and the lower steel reinforced column section is rotated, so that after each upper lug plate on the outer wall of the upper steel reinforced column section is aligned with the corresponding upper lug plate on the outer wall of the lower steel reinforced column section, the upper steel reinforced column section descends by a certain height until the upper steel reinforced column section makes contact with the lower steel reinforced column section, and then welding is carried out. Through the method, the problem that accumulated errors are too large can be solved, engineering cost can be saved, working efficiency can be improved, and the common quality problem that control is difficult in a steel structure construction process is solved effectively through structural improvement measures.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method based on the splicing of steel columns on a construction site. Background technique [0002] In the construction process of multi-level and high-rise steel structure projects, it is one of the common quality problems that often occur when the amount of misalignment of the spliced ​​butt welds of steel columns on the construction site exceeds the allowable deviation value of the specification. my country has developed rapidly in multi- and high-rise building steel structures. In July 2001, the Ministry of Construction approved the National Building Standard Design Atlas such as "Multi- and High-rise Civil Building Steel Structure Node Structure Details" (01SG519). This atlas provides the settings and structures of "column site splicing (1) and (2)", such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 shown. in figure 1 and figure 2 It...
