Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure engineering, specifically a steel column anti-torsion support structure. Background Technology
[0002] Steel structure workshops are usually equipped with cranes for production needs. In some cases, due to requirements such as maintenance access and process layout, the crane brackets or cantilever arms extend to a large length, and the longitudinal braking force of the crane will generate a large torque on the steel columns.
[0003] Compared to their bending and shear resistance, the torsional resistance of I-shaped open-section columns commonly used in steel structure workshops is very weak. In design, the influence of this torque is often ignored or lattice columns, box columns, and other methods are used to bear the torque, which brings safety hazards to the design of new steel structure workshops and the renovation and reinforcement of existing projects.
[0004] To address the aforementioned issues, we have made improvements and proposed a steel column anti-torsion support structure. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] This utility model provides a steel column anti-torsion support structure, including a pair of steel columns, which are fixedly installed on the ground. A crane beam is fixedly installed at the top of the pair of steel columns, and a support block is installed at the middle of the bottom end of the crane beam. A support column is fixedly connected to the bottom end of the support block, and a first connecting seat is fixedly connected to the bottom end of the support column, which is also fixedly installed on the ground. A fixing plate is fixedly connected to the middle of the support column, and diagonal bracing columns are installed on both the left and right sides of the top of the fixing plate. The top ends of the two diagonal bracing columns are respectively connected to the top ends of the two steel columns.
[0007] As a preferred embodiment of this utility model, a connecting block is installed at the top of the diagonal bracing column, and a connecting member is fixedly connected to the outside of the connecting block, and the connecting member is fixedly connected to the top of the steel column.
[0008] As a preferred embodiment of this utility model, a triangular block is installed at the top of the inclined support column, and the triangular block is fixedly connected to the bottom of the connecting block.
[0009] As a preferred embodiment of this utility model, a reinforcing rod is hinged to the middle of the diagonal support column, and a second connecting seat is hinged to the bottom end of the reinforcing rod, and the second connecting seat is fixedly installed on the ground.
[0010] As a preferred technical solution of this utility model, multiple mounting bolts are fixedly connected to the top left and right sides of the fixing plate, and mounting plates are provided on the outer side of the multiple mounting bolts. The mounting plates are connected to the diagonal brace column by bolts, and fastening nuts are threaded on the outer side of the mounting bolts. The fastening nuts are located above the mounting plates.
[0011] As a preferred embodiment of this utility model, the outer thread of the mounting bolt is connected to an adjusting nut, and the adjusting nut is located below the mounting plate.
[0012] The beneficial effects of this utility model are:
[0013] 1. In this utility model, a support block is installed at the bottom center of the crane beam. The support block is embedded inside the crane beam. The support block supports the middle of the crane beam through a support column fixed to the ground. A fixing plate is installed in the middle of the support column. The diagonal bracing columns on both sides of the fixing plate support the connection between the crane beam and the steel column. When the crane beam is subjected to longitudinal braking force from the crane, the torque on the steel column can be effectively reduced, which greatly improves the stress condition of the steel column.
[0014] 2. In this utility model, rotating the adjusting nut changes the height of the adjusting nut on the mounting bolt, thereby changing the position of the mounting plate on the mounting bolt. This allows for adjustment of the distance between the mounting plate and the top of the steel column, adapting to the length of the diagonal brace column and facilitating its installation.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0021] Example: Figure 1 - Figure 3 As shown, a steel column anti-torsion support structure includes a pair of steel columns 1, which are fixedly installed on the ground. A crane beam 2 is fixedly installed at the top of the pair of steel columns 1. A support block 9 is installed at the middle of the bottom end of the crane beam 2. A support column 3 is fixedly connected to the bottom end of the support block 9. A first connecting seat 4 is fixedly connected to the bottom end of the support column 3, and the first connecting seat 4 is fixedly installed on the ground. A fixing plate 5 is fixedly connected to the middle of the support column 3. Diagonal bracing columns 6 are installed on both the left and right sides of the top of the fixing plate 5. The tops of the two diagonal bracing columns 6 are respectively connected to the tops of the two steel columns 1.
[0022] A support block 9 is installed at the bottom center of the crane beam 2. The support block 9 is embedded inside the crane beam 2. The support block 9 supports the middle of the crane beam 2 through the support column 3 fixed to the ground. A fixing plate 5 is installed in the middle of the support column 3. The diagonal bracing columns 6 on both sides of the fixing plate 5 support the connection between the crane beam 2 and the steel column 1. When the crane beam 2 is subjected to the longitudinal braking force from the crane, the torque on the steel column 1 can be effectively reduced, which greatly improves the stress condition of the steel column 1.
[0023] Specifically, such as Figure 1 and Figure 2 As shown, a connecting block 11 is installed at the top of the diagonal brace column 6, and a connector 10 is fixedly connected to the outside of the connecting block 11. The connector 10 is fixedly connected to the top of the steel column 1. A triangular block 12 is installed at the top of the diagonal brace column 6, and the triangular block 12 is fixedly connected to the bottom of the connecting block 11. The diagonal brace column 6 is connected to the steel column 1 through the connector 10, the connecting block 11 and the triangular block 12. The triangular block 12 guides the force evenly to the diagonal brace column 6.
[0024] Specifically, such as Figure 1 As shown, a reinforcing rod 7 is hinged to the middle of the diagonal brace column 6, and a second connecting seat 8 is hinged to the bottom end of the reinforcing rod 7. The second connecting seat 8 is fixedly installed on the ground. The reinforcing rod 7 is installed in the middle of the diagonal brace column 6 and is installed on the ground through the second connecting seat 8. The reinforcing rod 7 supports the diagonal brace column 6 and improves the strength of the diagonal brace column 6.
[0025] Specifically, such as Figure 2 and Figure 3As shown, multiple mounting bolts 13 are fixedly connected to the top left and right sides of the fixed plate 5. Mounting plates 14 are provided on the outer side of the multiple mounting bolts 13, and the mounting plates 14 are connected to the diagonal brace column 6 by bolts. The outer side of the mounting bolts 13 is threaded with fastening nuts 16, and the fastening nuts 16 are located above the mounting plates 14. The outer side of the mounting bolts 13 is threaded with adjusting nuts 15, and the adjusting nuts 15 are located below the mounting plates 14. Rotating the adjusting nuts 15 changes the height of the adjusting nuts 15 on the mounting bolts 13, thereby changing the position of the mounting plates 14 on the mounting bolts 13. The distance between the mounting plates 14 and the top of the steel column 1 can be adjusted to match the length of the diagonal brace column 6, facilitating the installation of the diagonal brace column 6.
[0026] Working principle: The support column 3 is fixed to the ground below the crane beam 2 through the first connecting seat 4, and the support block 9 is embedded in the bottom of the crane beam 2. The connecting block 11 is fixed in the connecting piece 10. The diagonal brace 6 is connected to the bottom end of the triangular block 12. Then, the position of the mounting plate 14 on the mounting bolt 13 is changed by rotating the adjusting nut 15 to match the length of the diagonal brace 6. Then, the bottom end of the diagonal brace 6 is installed on the mounting plate 14. The reinforcing rod 7 is installed in the middle of the diagonal brace 6. The reinforcing rod 7 is fixed to the ground through the second connecting seat 8 to strengthen the diagonal brace 6.
[0027] When the crane beam 2 is subjected to longitudinal braking force from the crane, the support block 9 supports the middle part of the crane beam 2 through the support column 3 fixed to the ground. The fixing plate 5 is installed in the middle of the support column 3, and the diagonal bracing columns 6 on both sides of the fixing plate 5 support the connection position between the crane beam 2 and the steel column 1, which can effectively reduce the torque on the steel column 1 and greatly improve the stress condition of the steel column 1.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
