Description

Technical Field

[0001] This utility model belongs to the field of prefabricated steel structure building technology, specifically relating to a simple truss beam and steel column connection structure for prefabricated steel structures. Background Technology

[0002] Steel structure buildings are one of the building structure forms that my country has explicitly mandated to develop vigorously. They can be divided into two main types: traditional steel structure buildings and prefabricated steel structure buildings. Steel structure buildings possess numerous significant advantages: mature structural design, convenient production, comprehensive construction measures, fast construction period, light weight, low waste emissions, and good durability. In my country, steel structure buildings have been widely used in both industrial and civil industrial buildings. Compared with traditional concrete buildings, steel structure buildings have a clear advantage in carbon emissions, which is of great significance for my country to achieve its ambitious goal of carbon peaking and carbon neutrality, and can make a positive and powerful contribution.

[0003] However, there are some issues that need optimization when prefabricated steel structures are applied to multi-story and low-rise buildings. The beam and column cross-sections and connection methods used are identical to those used in high-rise steel structures. This results in identical operational procedures for production, transportation, and on-site installation, making the entire construction process relatively complex, increasing construction difficulty and costs, and to some extent affecting the efficiency of large-scale promotion and application of prefabricated steel structures in multi-story and low-rise buildings. This situation urgently needs to be addressed through technological innovation and process improvement to fully leverage the advantages of prefabricated steel structures and promote high-quality development in the construction industry. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a simple prefabricated steel structure truss beam and steel column connection structure.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] This utility model provides a prefabricated steel structure simple truss beam and steel column connection structure, including an upper structural column, a lower structural column, a beam-column joint, and a truss beam. The beam-column joint is set between the upper and lower structural columns for connecting the two. The beam-column joint includes a joint column, a flange plate, and a vertical connecting plate. The top and bottom of the beam-column joint are fixedly provided with flange plates, and the side walls of the beam-column joint are also fixedly provided with vertical connecting plates for connecting with the truss beam. The vertical connecting plate has several through holes for installing fasteners. The top and bottom of the upper and lower structural columns are also fixedly provided with flange plates. Each flange plate has several through holes for installing fasteners.

[0007] Preferably, the node column, flange plate, and vertical connecting plate in the beam-column joint are pre-fixed as a whole in the factory by welding.

[0008] Preferably, the flange plates at the top and bottom of the upper and lower structural columns are all pre-fixed as a whole in the factory by welding.

[0009] Preferably, the fastener is a high-strength bolt.

[0010] Preferably, the cross-sectional dimensions of the node column are the same as those of the upper and lower structural columns.

[0011] Preferably, both the upper and lower structural columns are steel columns.

[0012] Preferably, the node column is a steel column.

[0013] Preferably, the upper chord, lower chord, and web members of the truss beam are all made of angle steel.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] (1) This utility model optimizes the connection structure between the upper and lower layers of the prefabricated steel structure, shortens the steel column length of the node column in the middle of the beam-column joint used for connection, and both the beam-column joint and the truss beam are prefabricated in the factory. The beam-column joint, as the intermediate component connecting the upper and lower structural columns, adopts bolt connection. This design eliminates the need for "hot welding" on the construction site, further simplifies the construction process, and makes the production, processing, transportation and on-site installation process more convenient and efficient.

[0016] (2) The steel beam in this utility model has been optimized and upgraded, and it has been changed to a truss-type steel beam. The truss-type steel beam can withstand the internal forces of multi-story and low-rise prefabricated steel structure buildings. Compared with solid web steel beams, it uses less steel and is lighter, which greatly improves the convenience of transportation and on-site installation. Attached Figure Description

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.

[0022] like Figure 1 As shown, as a preferred embodiment of the present utility model, this embodiment provides a prefabricated steel structure simple truss beam and steel column connection structure, including upper structural column 1, lower structural column 2, beam-column node 3 and truss beam 5, wherein the beam-column node 3 is set between the upper structural column 1 and the lower structural column 2 for connecting the upper structural column 1 and the lower structural column 2.

[0023] In the structure provided by this utility model, the beam-column node 3 includes a node column 301, a flange plate 302, and a vertical connecting plate 303. In this embodiment, both the upper structural column 1 and the lower structural column 2 are steel columns in prefabricated steel structure buildings, and the node column 301 is also a steel column. The cross-sectional dimensions of the node column 301 are the same as those of the upper structural column 1 and the lower structural column 2. To facilitate the fixed connection between the upper structural column 1, the lower structural column 2, and the intermediate beam-column node 3, the top and bottom of the upper structural column 1 and the lower structural column 2 are fixedly installed with flange plates 302 by welding, and the top and bottom of the beam-column node 3 are also fixedly installed with flange plates 302, as detailed below. Figure 2 and Figure 3 As shown. Each flange plate 302 has several through holes for mounting fasteners 4. In this embodiment, high-strength bolts are used as fasteners 4 to fix the flange plate 302 at the bottom of the upper structural column 1 and the flange plate 302 at the top of the beam-column node 3, and to fix the flange plate 302 at the top of the lower structural column 2 and the flange plate 302 at the bottom of the beam-column node 3.

[0024] like Figure 1 and Figure 2 As shown, a vertical connecting plate 303 for connecting with the truss beam 5 is also fixedly installed on the side wall of the beam-column node 3. In this embodiment, the upper chord, lower chord, and web members of the truss beam 5 are all made of angle steel. The upper chord and lower chord each consist of two angle steels with the same structure. During installation, the vertical connecting plate 303 is inserted between the two angle steels and welded to fix them.

[0025] It should be noted that, in order to improve the work efficiency on the construction site, the beam-column node 3 used in this embodiment can be pre-fixed into a whole in the factory by welding the node column 301, flange plate 302 and vertical connecting plate 303. The flange plates 302 at the top and bottom of the upper structural column 1 and the lower structural column 2 are also pre-fixed into a whole in the factory by welding.

[0026] In actual construction, the prefabricated components are transported to the construction site. First, the lower structural column 2 is fixed. Then, the beam-column node 3 is installed on the flange plate 302 at the top of the lower structural column 2, and the flange plate 302 at the bottom of the node column 301 is fixedly connected to the flange plate 302 at the top of the lower structural column 2 using bolts. Subsequently, the truss beam 5 and the vertical connecting plate 303 are fixedly connected using bolts. Then, the upper structural column 1 is fixedly connected, and the flange plate 302 at the top of the node column 301 is fixedly connected to the flange plate 302 at the bottom of the upper structural column 1 using bolts. This process is repeated until the entire prefabricated steel structure is assembled.

[0027] The embodiments described above are merely preferred solutions of this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
