Description

Technical Field

[0001] This utility model belongs to the field of steel structure column base bolts, and specifically relates to an installation structure for steel column base structures. Background Technology

[0002] With the increasing use of steel structures in urban construction, steel columns, as the framework of steel structures, are found on every steel structure construction site.

[0003] Currently, during the construction of column base embedded parts, the area outside the column base is usually poured first, leaving a pit for pouring space at the column base. After the outer concrete reaches its strength, concrete is poured into the pit at the column base. Then, the column base bolts are inserted into the column base embedded steel plate and then inserted into the concrete. The column base bolts are inserted into the concrete, and the column base embedded steel plate is located at the top of the concrete and flush with the concrete surface. After solidification, the column base embedding is completed. However, the height of the column base bolts and the column base embedded steel plate is difficult to control, resulting in poor column base quality. Utility Model Content

[0004] This utility model provides an installation structure for a steel column base structure to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an installation structure for a steel column base structure, installed on the outside of the column base on poured concrete. The installation structure includes a height adjustment screw located on the poured concrete, a horizontal mounting frame installed on the height adjustment screw, and a height adjustment seat located on the horizontal mounting frame. The column base structure includes a column base embedded steel plate and column base bolts. Multiple column base bolts are provided. The column base embedded steel plate has column base bolt holes corresponding to the column base bolts. The column base embedded steel plate also has height adjustment bolt holes. The height adjustment bolts are threadedly connected to the height adjustment bolt holes. The height adjustment seat is U-shaped and includes two vertical plates fixed to the bottom of the horizontal mounting frame and a height adjustment mounting plate located between the bottoms of the two vertical plates. The nuts of the height adjustment bolts are located between the height adjustment mounting plate and the mounting frame, and the height adjustment bolts are threadedly connected to the height adjustment mounting plate.

[0006] By adopting the above technical solution, an installation structure is set up on the poured concrete. Threaded holes are additionally opened on the pre-embedded steel plate at the column base, and height-adjusting bolts are screwed in for connection and fixation. The height-adjusting bolts are threaded onto the height-adjusting seats on the mounting frame. Therefore, when the mounting frame moves up and down, it can drive the pre-embedded steel plate at the column base to move up and down. Finally, the height of the pre-embedded steel plate at the column base is adjusted by adjusting the overall height of the mounting frame using height-adjusting screws. This allows for relatively precise control of the height of the pre-embedded steel plate at the column base, ensuring better construction quality.

[0007] Preferably, the column base embedded steel plate is rectangular, and there are four height adjustment bolt holes, which are respectively located in the middle of the four sides. The height adjustment seat is provided on the mounting frame, and the mounting frame is cross-shaped.

[0008] By adopting the above technical solution, the column base embedded steel plate is fixed in four places, resulting in strong structural stability and good levelness.

[0009] Preferably, a disc seat is fixed to the bottom end of the height adjustment screw, a height adjustment nut is threaded onto the height adjustment screw, and the mounting bracket is sleeved on the height adjustment screw and supported on the height adjustment nut.

[0010] By adopting the above technical solution, the height of the mounting bracket can be adjusted, and the structure is easy to manufacture.

[0011] Preferably, a horizontally rotating rod is fixedly welded onto the height-adjusting nut, and two rotating rods are provided symmetrically on the height-adjusting nut.

[0012] By adopting the above technical solution, the rotation can be manually controlled and the height of the mounting frame can be adjusted.

[0013] Preferably, the height adjustment nut is also threadedly connected to an anti-loosening nut located above the mounting bracket.

[0014] By adopting the above technical solution, the mounting bracket is prevented from detaching from the height adjustment nut.

[0015] Preferably, the mounting frame is a steel pipe structure.

[0016] By adopting the above technical solutions, the steel pipe structure is lightweight and high-strength, the materials are readily available, and the performance is good.

[0017] The beneficial effects of this utility model are as follows: An installation structure is set up on the poured concrete; additional threaded holes are made in the pre-embedded steel plate at the column base, and height-adjusting bolts are screwed in for connection and fixation. The height-adjusting bolts are threaded onto the height-adjusting seats on the mounting frame. Therefore, when the mounting frame moves up and down, it can drive the pre-embedded steel plate at the column base to move up and down. Finally, the height of the pre-embedded steel plate at the column base is adjusted by adjusting the overall height of the mounting frame using the height-adjusting screw. This allows for relatively precise control of the height of the pre-embedded steel plate at the column base, ensuring better construction quality.

[0018] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention; the main objectives and other advantages of this invention may be realized and obtained by means of the methods particularly pointed out in the description.
