Description

Technical Field

[0001] The present invention relates to the technical field of building steel structures, and particularly to a box column member with high stability for building steel structures. Background Technique

[0002] A box column member with high stability for building steel structures is an important vertical load-bearing member used in building structures, mainly used to bear the vertical loads (such as self-weight, service loads, etc.) and horizontal loads (such as wind loads, seismic actions, etc.) of buildings. A box column member with high stability for building steel structures is a closed-section member welded by multiple steel plates. Its cross-section is usually rectangular or square, and the inside can be hollow or filled with materials such as concrete. The structural design of the box column enables it to have high compressive, flexural, and torsional resistance when bearing loads.

[0003] Referring to the Chinese patent authorization announcement number CN222009366U, the authorization announcement date is November 15, 2024, which discloses a column member of a building steel structure, belonging to the technical field of building steel structures. It includes a box column, a cross column arranged inside the box column, and stud bolts laid on the wall of the box column. The cross column is formed by two groups of steel plates intersecting perpendicularly, and the cross column divides the inside of the box column into four regions with the same volume; the main body of the box column includes a corrugated web box and wing plate boxes located on both the head and tail sides of the corrugated web box. The corrugated web box and the wing plate boxes are of an integral structure, and the box body plate of the corrugated web box uses a corrugated folded plate; installation through holes are arranged on the wall of the corrugated web box. The column member of the present invention, through the synergistic effect among the corrugated folded plate, the built-in stud bolts, and the cross column, better improves the mechanical properties such as stability, planar stiffness, and bearing capacity; after subsequent concrete pouring, a larger contact surface is formed, which can effectively improve the adhesion between the inside of the box column and the concrete, and further improve the axial compression performance of the final product.

The internal component structure 3 is located between the auxiliary structures 8. External component structures 5 are installed at the front and rear ends on the outer side of the second side plate 2. Stud bolts 4, X-shaped fixing plates 6 and mounting plates 9 are fixedly connected to the outer sides of the first side plate 1 and the second side plate 2. The stud bolts 4 and the X-shaped fixing plates 6 are located between the mounting plates 9, and the stud bolts 4 are located below the X-shaped fixing plates 6. Auxiliary structures 8 are installed at the bottom and top inside the first side plate 1 and the second side plate 2. A fixed base 7 is installed at the bottom of the first side plate 1 and the second side plate 2;

[0034] As Figures 3-5 and Figure 8 shown, the internal component structure 3 includes a first fixing plate 301, a second fixing plate 302, a first X-shaped rod 303, a second X-shaped rod 304 and a fixing rod 305. The first side plate 1 and the second side plate 2 are welded to each other in pairs to form a box. The first fixing plate 301 and the second fixing plate 302 are welded equidistantly inside the box to improve the connection stability between the first side plate 1 and the second side plate 2;

[0035] The second fixing plate 302 is arranged below the first fixing plate 301. The bottom end of the first fixing plate 301 and the top end of the second fixing plate 302 are fixedly connected with the first X-shaped rod 303. The bottom end of the second fixing plate 302 and the top end of the first fixing plate 301 are fixedly connected with the second X-shaped rod 304, and the first X-shaped rod 303 and the second X-shaped rod 304 are simultaneously fixedly connected with the first side plate 1 and the second side plate 2, so that the first X-shaped rod 303 and the second X-shaped rod 304 improve the overall internal stability and compressive resistance of the box column member. Fixing rods 305 are fixedly connected inside the four corners of the first fixing plate 301 and the second fixing plate 302 to further improve the stability of all the first fixing plates 301 and the second fixing plates 302. The bottom of the fixing rod 305 can be inserted into the ground and its connecting parts, thereby improving the connection stability between the box column member and the ground.

Place the second box column member on the top of the first box column member, so that the convex ring 801 is snap - connected into the concave ring 802, and the upper and lower mounting plates 9 are fixed with screws, which is convenient for the staff to weld. First, weld the internal convex ring 801 and concave ring 802, and then weld the first side plate 1 and the second side plate 2 respectively, thereby improving the connection stability of the two box column members;

[0040] As Figures 1-4 and Figure 6 shown, stud bolts 4 and X - shaped fixing plates 6 are fixedly connected to the outer sides of both the first side plate 1 and the second side plate 2. The X - shaped fixing plate 6 can further improve the strength of the first side plate 1 and the second side plate 2, and the stud bolts 4 can improve the overall stability of the box column member.
