Description

Technical Field

[0001] The present application relates to the field of steel column reinforcement technology, and in particular to a steel structure reinforcement structure for old factory buildings. Background Art

[0002] Steel structure workshops are buildings whose primary load-bearing components are made of steel, including steel columns, beams, foundations, roof trusses, and roofs. Steel structure workshops are characterized by their light weight, high strength, large spans, and short construction periods, and are widely used in various industrial and civil construction facilities.

[0003] After long-term use, steel structure workshops require reinforcement and renovation. Due to the limited cross-sectional shape of H-shaped steel columns, it is difficult to directly reinforce the original H-shaped steel columns. Currently, the method of adding steel columns in the places with larger loads in the workshop is usually adopted to support the upper structure and thus improve the stability of the steel structure workshop. However, when reinforcing and renovating steel structure workshops such as those with large lifting equipment, the design location of the newly added steel columns will be greatly limited due to the large amount of equipment in the workshop, resulting in the problem that the reinforcement effect of the steel structure workshop is difficult to meet the design requirements.

[0015] By adopting the above technical solution, two L-shaped positioning plates form a positioning space on the reinforcement steel for the reinforcement steel to be welded to be inserted, thereby improving the stability of the reinforcement steel to be welded on the welded reinforcement steel.

[0016] Optionally, the reinforcing steel is provided with ribs for supporting the flange plates of the H-shaped steel columns.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] Example 1

[0032] The embodiment of the present application discloses a reinforcement structure for an old steel-structured factory building.

[0033] Reference Figure 1The reinforcement structure of the old steel factory building includes reinforcing steel 1. The reinforcing steel 1 is T-shaped steel. There is one reinforcing steel 1 welded on both sides of the web of the H-shaped steel column. The web of the reinforcing steel 1 away from the flange side is welded to the midpoint of the web of the H-shaped steel column. The two reinforcing steels 1 are distributed in opposite directions on both sides of the web of the H-shaped steel column.

[0034] The implementation principle of Example 1 of the present application is: the construction workers directly weld two reinforcing steels 1 symmetrically on both sides of the web of the H-shaped steel column, so that the web of the reinforcing steel 1 away from the flange side is located at the midpoint of the web of the H-shaped steel column, and the reinforcing steel 1 can support the H-shaped steel column. When the H-shaped steel column is subjected to bending moment, the reinforcing steel 1 evenly supports both sides of the web of the H-shaped steel column, reducing the possibility of the H-shaped steel column deforming toward the reinforced weak side, and improving the bending moment bearing capacity of the H-shaped steel column on both sides of the web where the bending moment is weaker, thereby improving the structural strength of the original H-shaped steel column of the steel structure factory building, reducing the demand for new steel columns when reinforcing the steel structure factory building, and directly reinforcing the original H-shaped steel column of the steel structure factory building, effectively improving the reinforcement effect of the steel structure factory building.

[0035] Example 2

[0036] Reference Figure 2 , the difference between Example 2 of the present application and Example 1 is that: a positioning mechanism 2 is installed on the reinforcing steel 1, and the positioning mechanism 2 is used to position the adjacent reinforcing steel 1. The positioning mechanism 2 includes a positioning plate 21, a slide plate 22 and a positioning member 23. The cross-section of the positioning plate 21 is L-shaped, and one positioning plate 21 is welded and installed on both sides of the web of the reinforcing steel 1, and the positioning plate 21 extends to be parallel to the flange plate of the reinforcing steel 1, and the slide plate 22 is slidably installed on the reinforcing steel 1 in the direction toward the flange plate of the reinforcing steel 1; the positioning member 23 is installed on the reinforcing steel 1, and the positioning member 23 is used to position the slide plate 22. The positioning member 23 includes a positioning bolt 231, which is slidably penetrated on the slide plate 22, and the positioning bolt 231 is threadedly connected to the positioning plate 21.

[0037] When the construction workers overlap and install multiple reinforcing steels 1 in the height direction of the H-shaped steel column, the reinforcing steel 1 to be welded is overlapped on the welded reinforcing steel 1. At this time, the reinforcing steel 1 to be welded is stuck in the T-shaped space formed by the two positioning plates 21, and the reinforcing steel 1 to be welded is positioned on the welded reinforcing steel 1, thereby improving the stability of the reinforcing steel 1 to be welded on the welded reinforcing steel 1. Then the construction workers push the slide plate 22 so that the slide plate 22 abuts against the reinforcing steel 1 to be welded, and then rotate the positioning bolt 231 so that the head of the positioning bolt 231 presses the slide plate 22 against the reinforcing steel 1 to be welded, conveniently positioning the slide plate 22 in a state of pressing against the reinforcing steel 1 to be welded, and then the reinforcing steel 1 to be welded can be positioned on the welded reinforcing steel 1, which is convenient for the construction workers to position the reinforcing steel 1 to be welded on the H-shaped steel column, and then facilitate the construction workers to perform welding.

[0038] Reference Figure 2 、 Figure 3 A rib 3 is installed between the flange plate of the reinforcing steel 1 and the flange plate of the H-shaped steel column. The rib 3 is used to support the flange plate of the H-shaped steel column. The rib 3 includes a support sleeve 31, a support plate 32 and an adjusting member 33. The support sleeve 31 is hollow inside and open at one end. The support plate 32 is slidably inserted into the support sleeve 31 along the opening direction of the support sleeve 31; the adjusting member 33 is installed on the support sleeve 31, and the adjusting member 33 is used to drive the support plate 32 to slide in the direction away from the support sleeve 31. Component 33 includes a screw rod 331 and a wedge block 332. The screw rod 331 is rotatably mounted on the support sleeve 31. The wedge block 332 is slidably mounted on the inner wall of the support sleeve 31 in a direction perpendicular to the opening direction of the support sleeve 31. The wedge block 332 is provided with an inclined surface on the side facing the opening of the support sleeve 31. The wedge block 332 is threadedly connected to the screw rod 331. The side of the support plate 32 facing the wedge block 332 is usually inclined, and the inclined surface of the wedge block 332 abuts against the inclined side of the support plate 32.

[0039] The construction workers insert the support sleeve 31 and the support plate 32 between the flange plate of the reinforcing steel 1 and the flange plate of the H-shaped steel column, and then rotate the screw 331 so that the screw 331 drives the wedge block 332 to slide in the direction close to the support plate 32. The inclined surface on the wedge block 332 squeezes the support plate 32, which can make the support plate 32 move in the direction away from the support sleeve 31, so that the support sleeve 31 and the support plate 32 are respectively pressed against the flange plate of the reinforcing steel 1 and the flange plate of the H-shaped steel column, completing the positioning and installation of the rib plate 3 between the flange plate of the reinforcing steel 1 and the flange plate of the H-shaped steel column. Subsequently, the rib plate 3 supports the flange plate of the H-shaped steel column, further improving the structural strength of the H-shaped steel column.
