Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, and in particular to a quick positioning device for a cup-shaped foundation steel structure box column. Background Technology

[0002] Steel box-type columns are mainly used in high-rise steel frame and heavy steel structure factory buildings. They are widely used in steel structures due to their high strength, uniform material, good toughness, convenient fabrication and installation, and short construction period. The common foundation type for steel box-type columns is the cup-shaped foundation.

[0003] In traditional construction, the elevation of the bottom of the cup is measured first. If it is too high, it needs to be removed; if it is too low, shims are used to adjust it to the corresponding elevation. This installation method requires lifting the steel column multiple times to adjust the elevation. At the same time, the steel column needs to be fixed with guy ropes. However, the reserved size of the cup is relatively large. The bottom of the steel column is suspended during the installation process, making it difficult to adjust its axis and elevation. If the shims at the bottom are not fixed firmly, the elevation deviation may be too large and cannot be adjusted.

[0004] In summary, the traditional construction method of box-type column cup-mouth foundation has significant drawbacks: the steel column hoisting time is long, and it is difficult to adjust dimensional deviations, which affects the construction progress and installation quality. Utility Model Content

[0005] The purpose of this utility model is to solve the technical defects of existing installation methods, such as large construction deviations, low efficiency, high costs, and difficulty in adjusting deviations.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rapid positioning device for a cup-shaped foundation steel box column, comprising a cup-shaped foundation and a steel box column. The steel box column is positioned on top of the cup-shaped foundation, and positioning plates are fixedly connected to all four sides of the steel box column. Eight chemical anchors are embedded at the four corners of the top of the cup-shaped foundation. Positioning holes are provided on the positioning plates corresponding to the chemical anchors, and the chemical anchors are all positioned inside the positioning holes. Matching leveling nuts and washers are provided at the chemical anchors. Limiting blocks are provided between the lower ends of both sides of the steel box column and the cup-shaped foundation. The device can adjust the elevation dimensions through the leveling nuts, which can prevent large deviations in elevation dimensions and effectively improve construction progress and installation quality.

[0007] As a preferred embodiment, the steel box column and the positioning plate are integrally molded to ensure the rigidity of the positioning plate.

[0008] In a preferred embodiment, a stiffening plate is provided between the positioning plate and the steel box column. The two perpendicular side walls of the stiffening plate are fixedly connected to the steel box column and the positioning plate, respectively. By increasing the strength and rigidity between the steel box column and the positioning plate, the overall performance and stability of the structure are enhanced.

[0009] In a preferred embodiment, the bottom elevation of the positioning plate needs to be higher than the top elevation of the foundation at the cup opening by mm to facilitate adjustment during steel column installation.

[0010] In a preferred embodiment, the positioning plate has positioning holes corresponding to the chemical anchor bolts, and the positioning holes are at least mm away from the inner wall of the cup base to facilitate elevation adjustment.

[0011] In a preferred embodiment, the limiting block is a wedge-shaped block, and the inclined side of the limiting block abuts against the top of the cup-shaped foundation. By striking the limiting block, the steel box column can be fixed.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This utility model includes components such as a leveling nut, a positioning plate, and chemical anchors. The device can adjust the elevation dimensions through the leveling nut, which can prevent large deviations in elevation dimensions and effectively improve construction progress and installation quality.

[0014] This utility model includes stiffening plates and other components. The steel box column and the positioning plate are integrally molded, which can ensure the rigidity of the positioning plate. The stiffening plates improve the strength and rigidity between the steel box column and the positioning plate, enhance the overall performance and stability of the structure, and prevent the positioning plate from deforming due to the weight of the steel column during installation.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a rapid positioning device for a cup-shaped foundation steel box column, including a cup-shaped foundation 1 and a steel box column 2. The steel box column 2 is set on the top of the cup-shaped foundation 1. Positioning plates 3 are fixedly connected to all four sides of the steel box column 2. Eight chemical anchors 4 are inserted at the four corners of the top of the cup-shaped foundation 1. Positioning holes are opened on the positioning plates 3 corresponding to the chemical anchors 4, and the chemical anchors 4 are all set inside the positioning holes. Matching leveling nuts 6 and washers 7 are set at the chemical anchors 4. Limiting blocks 5 are set between the lower ends of both sides of the steel box column 2 and the cup-shaped foundation 1. The diameter of the chemical anchors 4 is determined according to the weight of the steel column. The insertion depth of the chemical anchors 4 should not be less than 120mm, the exposed length should not be less than 100mm, and the matching leveling nuts 6 and washers 7 are placed in place. The device can adjust the elevation dimension through the leveling nuts 6, which can prevent the problem of large deviation in elevation dimension and effectively improve the construction progress and installation quality.

[0024] like Figure 1-5 As shown, the steel box column 2 and the positioning plate 3 are integrally formed, which can ensure the rigidity of the positioning plate 3.

[0025] like Figure 1-5 As shown, a stiffening plate 8 is provided between the positioning plate 3 and the steel box column 2. The two perpendicular side walls of the stiffening plate 8 are fixedly connected to the steel box column 2 and the positioning plate 3 respectively. The stiffening plate 8 improves the strength and rigidity between the steel box column 2 and the positioning plate 3, enhances the overall performance and stability of the structure, and prevents the positioning plate 3 from deforming due to its weight during the installation of the steel column.

[0026] like Figure 1-5 As shown, the bottom elevation of the positioning plate 3 needs to be 50mm higher than the top of the cup-mouth foundation 1 to facilitate adjustment during steel column installation.

[0027] like Figure 1-5As shown, positioning holes are provided on the positioning plate 3 at the locations corresponding to the chemical anchor bolts 4. The positioning holes are at least 80mm away from the inner wall of the cup-mouth foundation 1, which facilitates the adjustment of the elevation.

[0028] like Figure 1-5 As shown, the limiting block 5 is a wedge-shaped block. The inclined side of the limiting block 5 abuts against the top of the cup-shaped foundation 1. By striking the limiting block 5, the steel box column 2 can be fixed.

[0029] Working principle: Before installing the steel column, measure the actual positioning dimensions of the steel column. Then, insert a total of eight chemical anchors 4 on each positioning plate 3 on the cup-mouth foundation 1, with an insertion depth of not less than 120mm and an exposed length of not less than 100mm. Place the matching leveling nuts 6 and washers 7 in place, measure and adjust the elevation of the leveling nuts 6 and the upper washers 7 so that their upper elevation is consistent with the bottom elevation of the steel column positioning plate 3. After the steel column is in place, measure the center line and verticality of the steel column and adjust it using the leveling nuts 6. After the steel column installation dimensions are adjusted to meet the specifications, use the limit blocks 5 to fix both sides of the steel column to ensure that the steel column does not move.
