Description

Technical Field

[0001] This utility model relates to the field of metallurgical engineering technology, and in particular to an adjustable height steel column base structure. Background Technology

[0002] In the field of metallurgical construction engineering, the column feet of steel frame columns or steel support columns are mostly connected by bolts or insert-type steel column feet. During their installation, a certain gap (such as 50mm) needs to be reserved between the column foot plate and the top surface of the foundation to adjust for errors in the construction and fabrication of the foundation or steel structure. After the steel column feet are installed, this gap needs to be filled with grout for secondary grouting. However, how to reserve the gap for secondary grouting is a problem that urgently needs to be solved. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an adjustable steel column base structure, which allows for free adjustment of the height of the steel column base during installation, ensuring both installation accuracy and ease of operation.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model provides an adjustable steel column base structure, including a column base plate and a steel column assembled on the column base plate, and further including an adjusting screw assembly and a check screw assembly disposed between the column base plate and the steel column; the adjusting screw assembly includes a first screw and an adjusting nut, and the check screw assembly includes a second screw and a check nut; mounting through holes for the first screw and the second screw are respectively provided on both sides of the weak axis center line of the column base plate, and the first screw and the second screw are respectively passed through the mounting through holes of the steel column and the column base plate, and the screw portion of the first screw protruding from the mounting through hole is fitted with the adjusting nut, and the screw portion of the second screw protruding from the mounting through hole is fitted with the check nut; the adjusting nut and the check nut are respectively used to abut against the column base plate.

[0006] Furthermore, the lengths of the first screw and the second screw are at least 100 mm.

[0007] Furthermore, the outer diameter of the lead screw portion of the first screw and the second screw is 16mm, and the inner diameter of the mounting through hole is 18mm.

[0015] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] Reference Figures 1 to 3 This embodiment provides an adjustable steel column base structure (hereinafter referred to as steel column base structure) to enable the steel column base to be adjusted in height during the installation of the steel structure.

[0018] like Figure 1 and Figure 3 As shown, the steel column base structure of this embodiment includes a column base plate 4 and a steel column 3 assembled on the column base plate 4. It also includes a height adjustment screw assembly 1 and a check screw assembly 2 disposed between the column base plate 4 and the steel column 3. The height adjustment screw assembly 1 includes a first screw 5 and a height adjustment nut 6, and the check screw assembly 2 includes a second screw and a check nut. Naturally, the structures of the first screw 5 and the second screw are similar, as are the structures of the height adjustment nut 6 and the check nut.

[0019] like Figure 2As shown, the column base plate 4 is provided with mounting through holes 41 that mate with the first screw 5 and the second screw. The two mounting through holes 41 are symmetrically distributed on both sides of the weak axis center line 7 of the column base plate 4, and the first screw 5 and the second screw are symmetrically distributed on both sides of the weak axis center line 7 of the steel column 3. At this time, the first screw 5 corresponds to one of the mounting through holes 41, and the second screw corresponds to the other mounting through hole 41.

[0020] The first screw 5 and the second screw are respectively inserted into the two mounting through holes 41 of the steel column 3 and the column base plate 4. The screw part of the first screw 5 protruding from one of the mounting through holes 41 is fitted with an adjusting nut 6, and the screw part of the second screw protruding from the other mounting through hole 41 is fitted with a check nut.

[0021] After the height of the steel column base is adjusted to the correct position, the height adjustment nut 6 and the check nut abut against the column base plate 4 to ensure that the gap between the column base plate 4 and the top surface of the foundation matches the thickness of the secondary grouting layer.

[0022] In this embodiment, the length of the first screw 5 and the second screw is at least 100mm, and the thickness is 50mm based on the secondary pouring requirement. After deducting the thickness of the column base plate 4, a certain range for column height adjustment is reserved.

[0023] More specifically, the outer diameter of the lead screw portion of the first screw 5 and the second screw is 16mm, and the inner diameter of each of the two mounting through holes 41 is 18mm.

[0024] During the installation of the steel column base, first adjust the protrusion length of the first screw 5 protruding from the installation through hole 41 to the thickness of the secondary grouting layer (approximately 50mm). Then, after the steel column 3 is installed in place, tighten the height adjustment nut 6 using an electric or manual wrench to ensure that the steel column base is installed at the design elevation. Then, adjust the check nut on the second screw to keep it at the same installation height as the height adjustment nut 6. This can prevent the height adjustment nut 6 from failing and increase the installation accuracy and stability of the steel column base.

[0025] After all the steel column bases are installed in place, a second grouting process will be carried out until the steel column base construction is completed.

[0026] In summary, by cooperating with the height adjustment screw assembly 1, the height of the steel column base can be easily adjusted during the installation process, thereby ensuring the installation accuracy of the steel column base and the thickness of the secondary grouting layer. Furthermore, by cooperating with the check screw assembly 2, the column base is prevented from falling off due to the failure of the height adjustment nut 6, thus increasing the stability of the steel column base during installation and ensuring the reliability and accuracy of the steel column base installation process.

[0027] In addition, this embodiment allows for free adjustment of the column base height to the predetermined installation position after the steel column 3 is hoisted into place, without the need for hoisting equipment such as cranes. Therefore, it eliminates the need for prolonged use of hoisting equipment for installation.

[0028] On the other hand, even if uneven settlement or other abnormalities occur in the foundation before the secondary pouring layer is poured, the consistency of the bottom elevation of the upper steel column base structure can be ensured by adjusting the height adjustment screw assembly 1.

[0029] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
