Description

Technical Field

[0001] This utility model belongs to the field of building steel structure technology, and in particular relates to a horizontal support component for steel truss columns in building steel structures. Background Technology

[0002] In large-span factory buildings, stadiums, convention centers, and other large-scale building structures, steel structures are widely used due to their advantages such as high strength, light weight, and fast construction speed. However, the support nodes of steel truss columns are often directly fixed without fully considering the inward deformation of the steel truss. Under complex load conditions, this can easily lead to torsional and bending deformation, changing the original support angle, weakening the support effect on the steel structure column, and reducing the load-bearing capacity and lateral displacement resistance of the structure. Therefore, it is necessary to provide a horizontal support component for steel truss columns in building steel structures, which adopts a bolted and welded fixing method to strengthen the connection strength between the steel truss and the steel structure column. At the same time, in conjunction with the internal bracing structure, it can enhance the deformation resistance of the steel truss and increase the overall strength of the steel structure.

[0020] In the following description, embodiments of the horizontal support member for steel truss columns in the building steel structure of this utility model will be described with reference to the accompanying drawings.

[0021] Figure 1-4This invention illustrates a horizontal support member for a steel truss column in a building steel structure according to an embodiment of the present invention. The member includes a first steel truss 2 located between two steel structural columns 1. Second steel trusses 3 are provided at the upper left and lower right of the first steel truss 2. Both the first and second steel trusses 2 and 3 are welded together from four angle steels. An angle iron is welded between two longitudinally distributed angle steels, and a steel plate is welded between two vertically distributed angle steels. Connecting plates 4 are provided at the middle of the front and rear sides of the first steel truss 2. A tie rod assembly 5 is provided between two connecting plates 4. The tie rod assembly 5 includes four first bolts 5 threaded onto the surface of the connecting plates 4. 1. A first bolt 51 penetrates the connecting plate 4 and is threadedly connected to the first steel truss 2. Two second bolts 52 are threadedly connected to the front and rear ends of the second steel truss 3 near the connecting plate 4. The second bolts 52 are threadedly connected to the connecting plate 4. Four threaded tie rods 53 are installed between the two connecting plates 4. A steel pipe 54 is fitted onto the surface of the threaded tie rod 53. The front and rear sides of the steel pipe 54 are tightly fitted to the inner wall of the second steel truss 3. A nut 55 is threadedly connected to the end of the threaded tie rod 53 away from the steel pipe 54. Assembly components 6 are provided at the ends of the first steel truss 2 and the second steel truss 3 away from the connecting plate 4. Assembly component 6 includes a base 61. A T-shaped steel plate 62 is welded to the side of the base 61 away from the steel structure column 1. The T-shaped steel plate 62 is welded to an adjacent first steel truss 2 or second steel truss 3. Two third bolts 63 are provided through the surface of the T-shaped steel plate 62. The base 61 and the first steel truss 2 or second steel truss 3 are fixedly connected by the third bolts 63. A fourth bolt 64 is provided through the front and rear ends of the side of the base 61 away from the steel structure column 1. The steel structure column 1 and the base 61 are fixedly connected by the fourth bolt 64. A transverse support steel plate 65 is provided between two bases 61 located at the same level. Bolt 64 penetrates the inner wall of the transverse support steel plate 65 and is welded to the steel structure column 1. Through the assembly component 6, the base 61 and the fourth bolt 64 work together to create a stable connection between the T-shaped steel plate 62 and the steel structure column 1, while also connecting and fixing the transverse support steel plate 65. In addition, with the T-shaped steel plate 62 and the third bolt 63 working together, a stable connection and accurate angular support are provided between the first steel truss 2 or the second steel truss 3 and the steel structure column 1, thereby improving the support strength of the first steel truss 2 and the second steel truss 3 for the two steel structure columns 1.

[0022] Working principle: When using this utility model, the user installs and fixes the base 61 to the steel structure column 1 using the fourth bolt 64, and simultaneously fixes the T-shaped steel plate 62. Then, the T-shaped steel plate 62 is welded to the first steel truss 2 and the second steel truss 3, and connected and fixed using the third bolt 63, so that the opposite ends of the two second steel trusses 3 are close to the first steel truss 2. The connecting plate 4 is fixed using the first bolt 51, so that the connecting plate 4 is stably installed on the front and rear sides of the first steel truss 2. Next, the steel pipe 54 is placed in the inner cavity of the second steel truss 3, and the threaded tie rod 53 passes through from the front side of one connecting plate 4 to the rear side of the other connecting plate 4, and the threaded tie rod 53 is connected to the front side of the connecting plate 4 and the connecting plate 4. The rear threaded nut 55 is used to tighten and fix the first bolt 51 by rotating the nut 55, thereby fixing the second steel truss 3 under the threaded compression of the steel pipe 54 and the nut 55. Then, the user turns the second bolt 52 into the connecting plate 4 from one side, so that the second bolt 52 passes through the inner cavity of the second steel truss 3 and is threadedly connected to the second steel truss 3. This allows the first steel truss 2 to form a firm connection with the second steel truss 3 through the connecting plate 4. At the same time, under the internal support of the steel pipe 54, the inner cavities of the second steel truss 3 and the first steel truss 2 are supported and limited, effectively preventing the first steel truss 2 or the second steel truss 3 from shrinking and deforming, thereby strengthening the support stability of the steel structure column 1.

[0023] In summary, the horizontal support components of the steel truss columns in this building's steel structure, through the combined use of the first steel truss 2, the second steel truss 3, and the connecting plate 4, provide horizontal support between the two first steel trusses 2, ensuring that the two first steel trusses 2 are in a parallel state. At the same time, the combined use of the tie rod assembly 5 and the connecting plate 4 strengthens and fixes the junction of the second steel truss 3 and the first steel truss 2, thereby achieving the purpose of stable and reliable connection and stable support angle.
