[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Figure 1 This is a structural schematic diagram of the detachable steel column auxiliary construction device according to an embodiment of the present utility model; Figure 2 This is an exploded view of the detachable steel column auxiliary construction device according to an embodiment of the present utility model; Figure 3 This is a schematic diagram of the structure of the lower connecting ear plate according to an embodiment of the present utility model.

[0029] like Figures 1-3 As shown in the figure, the detachable steel column auxiliary construction device proposed in this embodiment can be used for the construction of columns, and can also be used for the auxiliary construction of other steel structures that are connected vertically.

[0030] This detachable steel column auxiliary construction device includes two upper connecting lugs 1 vertically welded to the lower end of one side of the upper steel column 5 and two lower connecting lugs 2 vertically welded to the upper end of one side of the lower steel column 6. The two upper connecting lugs 1 are spaced apart, and the two lower connecting lugs 2 are spaced equally apart. The upper steel column 5 and the lower steel column 6 will be welded together vertically. The lower connecting lugs 2 and the upper connecting lugs 1 act as mounting plates, allowing connection to other facilities to assist in construction. The upper steel column 5 has only two welding points on the upper connecting lugs 1, and the lower steel column 6 has only two welding points on the lower connecting lugs 2, significantly reducing welding compared to existing steel column construction methods.

[0031] The upper steel column 5 is hoisted using hoisting equipment and placed on top of the lower steel column 6. After alignment, the two upper connecting lugs 1 and the two lower connecting lugs 2 are aligned vertically to connect them together. This stabilizes the upper steel column 5 and the lower steel column 6, facilitating welding. The aligned upper connecting lugs 1 and lower connecting lugs 2 can be connected together using detachable clamps 3. The two clamps 3 hold the aligned upper connecting lugs 1 and lower connecting lugs 2 in the middle and then connect them to the same vertical plane. The clamps 3 can be removed and reused after construction is completed.

[0032] The ladder 4, for workers to stand on, can be connected to two lower connecting lugs 2. Two vertical bars of the ladder 4 can be detachably connected to the lower ends of the two lower connecting lugs 2. The ladder 4 can be easily removed after construction is completed.

[0033] In one specific embodiment of this utility model, for ease of connection, the upper connecting ear plate 1 may include a first rectangular plate. First through holes 11 are uniformly arranged along the center line of the first rectangular plate's length direction. The edge of the first rectangular plate's length direction is welded to the side of the upper steel column 5, and the upper connecting ear plate 1 is perpendicular to the side of the upper steel column 5. The number of first through holes 11 on the upper connecting ear plate 1 may be three, facilitating alignment with the lower connecting ear plate and connection via the clamping plate 3.

[0034] In one specific embodiment of this utility model, in order to cooperate with the upper connecting ear plate 1, the lower connecting ear plate 2 may include a second rectangular plate and a strip plate connected to the lower end of the second rectangular plate. The second rectangular plate and the strip plate are on the same plane. Second through holes 21 are uniformly arranged along the center line of the length direction of the second rectangular plate. The diameter of the second through holes 21 is the same as that of the first through holes 11. The edge of the second rectangular plate along its length direction is welded to the side of the lower steel column 6. The lower connecting ear plate 2 is perpendicular to the side of the lower steel column 6. The second rectangular plate may have the same size as the first rectangular plate. The number of second through holes 21 may be 3. The second rectangular plate and the first rectangular plate may be symmetrical about the connection seam of the upper steel column 5 and the lower steel column 6, so as to facilitate the alignment of the second rectangular plate and the first rectangular plate and sandwich them in the middle of the two clamping plates 3.

[0035] In one specific embodiment of this utility model, the clamping plate 3 can be bolted to the upper and lower connecting ear plates. The clamping plate 3 may include a third rectangular plate, on which a third through hole 31 is provided, corresponding one-to-one with the first through hole 11 and the second through hole 21. The two clamping plates 3 are respectively clamped on both sides of the aligned first and second rectangular plates. The corresponding third through holes 31 and the first through hole 11, and the corresponding third through holes 31 and the second through hole 21 are respectively aligned and connected by bolts and nuts. The two rectangular plates with the third through holes 31 clamp the aligned first and second rectangular plates in the middle, stably limiting them to the same vertical plane, and then fastened together by bolts and nuts. This reduces the number of welding points while ensuring the stable connection between the upper steel column 5 and the lower steel column 6, providing convenience for the steel column welding construction.

[0036] In one specific embodiment of this utility model, in order to cooperate with the upper and lower connecting ear plates, the length of the third rectangular plate is equal to the distance between the opposite edges of the second and first rectangular plates, the width of the third rectangular plate is equal to the width of the first rectangular plate, and the third through hole 31 is set along the center line of the length direction of the third rectangular plate. The clamping plate 3 can be easily attached to both sides of the upper / lower connecting ear plates, and the third through hole 31 is easy and quick to align with the first through hole 11 / second through hole 21, making bolt insertion convenient.

[0037] In one specific embodiment of this utility model, the strip plate is used to connect tools such as the ladder 4. The width of the strip plate is smaller than the width of the second rectangular plate, and the edges of the strip plate and the second rectangular plate are aligned away from the lower steel column 6. The strip plate extends below the clamping plate 3 and can be connected to other construction facilities, which avoids welding the other facilities to the steel column.

[0038] In one specific embodiment of this utility model, for ease of connection, at least three fourth through holes 22 are evenly provided along the center line of the strip plate along its length. The fourth through holes 22 facilitate detachable connection with facilities such as the ladder 4 and fall arresters.

[0039] In one specific embodiment of this utility model, the ladder 4 is slightly modified. Mounting plates 41 are connected to the upper ends of both vertical bars of the ladder 4. Each mounting plate 41 has two connecting holes 42 spaced at the same distance as the adjacent fourth through holes 22. The distance between the two mounting plates 41 matches the distance between the two strip plates. After the two mounting plates 41 are respectively attached to the two strip plates, the connecting holes 42 are aligned with the corresponding fourth through holes 22 at the lower end of the strip plates and connected by bolts and nuts. After the mounting plates 41 are connected to the strip plates, the upper end of the mounting plate 41 does not exceed the third fourth through hole 22 counted from the bottom of the strip plate, and does not obstruct the connection of construction facilities to other third through holes 31. The corresponding mounting plates 41 and strip plates are installed through two mounting points, allowing for a stable and vertical connection of the ladder 4.

[0040] In one specific embodiment of this utility model, a fall arrestor can be connected to the fourth through hole 22 at the upper end of the strip plate. The fall arrestor can be connected to an unused fourth through hole 22. If there are still unused fourth through holes 22, other construction facilities can be connected to them, thus avoiding welding of construction facilities to the lower steel column 6.

[0041] In one specific embodiment of this utility model, for the sake of construction stability, two lower connecting lugs 2 are set at the middle of the side of the lower steel column 6, and two upper connecting lugs 1 are set at the middle of the side of the upper steel column 5. After the entire detachable steel column auxiliary construction device is installed, the ladder 4 is located in the middle of the steel column, ensuring safe and stable construction for personnel.

[0042] The detachable steel column auxiliary construction device according to the present invention is described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the detachable steel column auxiliary construction device proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
