Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular, to a highly stable prefabricated irregular steel connection structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components are usually connected by welding, bolting or riveting. Due to their light weight and simple construction, steel structures are widely used in factories, stadiums, bridges and other fields.

[0003] As mentioned earlier, when steel structure components are fixedly connected by welding, the components cannot be easily separated, affecting subsequent reuse and continuous use. In addition, welding places high demands on operators, and the use of welding equipment increases the company's production costs. On the other hand, when components are connected by simple bolts, the bolted joints on the side plates of the steel structure are prone to deformation due to insufficient strength when the steel structure is subjected to large loads, resulting in insufficient stability and requiring improvement in reliability. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a special-shaped steel connection structure with reliable use and strong connection stability is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a highly stable prefabricated irregular steel connection structure, including an irregular steel column and an I-beam. The irregular steel column includes two opposing vertical plates and two connecting plates connected between the two vertical plates. The connecting plates and the vertical plates form a C-shaped groove. A beam-column connector is installed in the C-shaped groove. A first bolt is installed on the irregular steel column. The tail end of the first bolt passes through the two connecting plates and the beam-column connector in sequence and is then fitted with a first nut. A second bolt is installed on the vertical plate. The tail end of the second bolt passes through the vertical plate, the beam-column connector, and the I-beam in sequence and is then fitted with a second nut. The beam-column connector includes a support plate, and the I-beam rests on the support plate.

[0006] Furthermore, the beam-column connector includes two oppositely arranged side plates and a middle plate vertically fixed between the two side plates. The two side plates are attached to the vertical plate, and the middle plate is attached to the connecting plate.

[0007] Furthermore, the I-beam includes two opposing flanges and a web plate vertically connected between the flanges, with the two flanges respectively abutting against the side plate and the bottom of the flanges resting against the support plate.

[0008] Furthermore, both the side plate and the wing plate are provided with mounting holes for installing the second bolt.

[0009] Furthermore, the mounting hole is an oblong hole.

[0010] Furthermore, the two upright plates are parallel to each other, and the two connecting plates are parallel to each other and perpendicular to each other.

[0011] Furthermore, there are two of each of the first bolts and the first nut, with the two first bolts being vertically distributed along the longitudinal direction and connected to the connecting plate.

[0012] Furthermore, the beam-column connector is an integrally formed structure.

[0013] The beneficial effects of this utility model are as follows: In the highly stable assembled irregular steel connection structure of this utility model, the first bolt passes through two connecting plates simultaneously, increasing the connection area between the first bolt and the connecting plates. Moreover, the two connecting plates are located at both ends of the first bolt, providing effective support for the first bolt and preventing deformation at the connection between the first bolt and the connecting plates, thus improving the connection strength. At the same time, the supporting plate on the beam-column connector can support the bottom of the I-beam, increasing the load-bearing capacity of the I-beam and preventing the I-beam from easily detaching from the irregular steel column, making the connection more stable and reliable.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please see Figures 1-5 This utility model provides a highly stable prefabricated irregular steel connection structure, including an irregular steel column 1 and an I-beam 2. The irregular steel column 1 includes two parallel vertical plates 11 and two connecting plates 12 connected between the two vertical plates 11. The two connecting plates 12 are parallel to each other and perpendicular to each other with respect to the vertical plates 11. The I-beam 2 is installed on the irregular steel column 1. In use, the irregular steel column 1 is installed vertically on the supporting plane (e.g., a factory building), and the I-beam 2 is installed horizontally and fixedly on the irregular steel column 1.

[0023] This utility model's high-stability prefabricated irregular steel connection structure also includes a beam-column connector 3. The beam-column connector 3 is detachably fixedly connected to the irregular steel column 1, and the I-beam 2 is detachably fixedly connected to the irregular steel column 1 via the beam-column connector 3. Both the beam-column connector 3 and the irregular steel column 1 and I-beam 2 are detachable, thus facilitating the removal of the I-beam 2 from the irregular steel column 1 and ensuring that the irregular steel column 1 and I-beam 2 can be reused repeatedly and continuously.

[0024] A C-shaped slot 101 is formed on one side of the irregular steel column 1. The C-shaped slot 101 is formed by the space enclosed by two upright plates 11 and a connecting plate 12. The beam-column connector 3 includes a C-shaped structure that fits into the C-shaped slot 101. The beam-column connector 3 is installed in the C-shaped slot 101. The beam-column connector 3 is detachably fixed to the connecting plate 12, thereby realizing the fixed connection relationship between the beam-column connector 3 and the irregular steel column 1.

[0025] In this embodiment, the beam-column connector 3 includes two opposing side plates 31 and a middle plate 32 vertically fixed between the two side plates 31. The two side plates 31 are parallel to each other, and the middle plate 32 is perpendicular to the side plates 31. In addition, the two side plates 31 are respectively attached to two opposing vertical plates 11, and the middle plate 32 is attached to the connecting plate 12. Because the side plates 31 are attached to the vertical plates 11 and the middle plate 32 is attached to the connecting plate 12, the structural strength of the irregular steel column 1 is enhanced, effectively reducing the deformation of the irregular steel column 1 when the I-beam 2 connected to the beam-column connector 3 is subjected to a large load.

[0026] A first bolt 4 is installed on the irregular steel column 1. The tail end of the first bolt 4 passes through two connecting plates 12 and an intermediate plate 32 in sequence, and then a first nut 5 is installed. Through the cooperation between the first bolt 4 and the first nut 5, the beam-column connector 3 is pressed and fixed onto the irregular steel column 1. In this embodiment, two first bolts 4 and two first nuts 5 are provided. The two first bolts 4 are distributed vertically along the longitudinal direction and connected to the connecting plates 12 to ensure balanced force distribution. The first bolt 4 passes through both connecting plates 12, increasing the connection area between the first bolt 4 and the connecting plates 12. The two connecting plates 12 are located at both ends of the first bolt 4, providing effective support for the first bolt 4, preventing deformation at the connection between the first bolt 4 and the connecting plates 12, and improving the connection strength.

[0027] The I-beam 2 includes two opposing flanges 21 and a web 22 vertically connected between the flanges 21. The two flanges 21 are respectively attached to the side plates 31. In this embodiment, a second bolt 6 is installed on the vertical plate 11. The tail end of the second bolt 6 passes through the vertical plate 11, the side plate 31 and the flange 21 in sequence and is then fitted with a second nut 7. Through the cooperation between the second bolt 6 and the second nut 7, the flange 21 is pressed and fixed onto the side plate 31, thereby realizing the fixed connection relationship between the irregular steel column 1, the beam-column connector 3 and the I-beam 2.

[0028] In this embodiment, both the side plate 31 and the wing plate 21 are provided with mounting holes 311 for the second bolt 6 to pass through. The mounting holes 311 are oblong holes, which are conducive to the installation of the second bolt 6 and avoid the situation where the second bolt 6 cannot be installed due to processing errors or assembly position deviations.

[0029] Please also refer to Figure 3 , Figure 5 The beam-column connector 3 also includes a support plate 33, which is horizontally fixed to the bottom of the two side plates 31, with the flange 21 resting on the support plate 33. After assembly, the flanges 21 on both sides of the I-beam 2 are fixed to the side plates 31 by the second bolts 6. At the same time, the bottom of the flanges 21 of the I-beam 2 is also supported by the support plate 33, increasing the load-bearing capacity of the I-beam 2 and further preventing the I-beam 2 from easily detaching from the irregular steel column 1.

[0030] In addition, there are two irregular steel columns 1, and both ends of the I-beam 2 are fixedly connected to the irregular steel column 1 through the beam-connector 3.

[0031] In this embodiment, the beam-column connector 3 is an integrally formed structure, which is convenient for processing and also helps enterprises control production costs.

[0032] In this utility model, the highly stable assembled irregular steel connection structure has a first bolt 4 that penetrates both connecting plates 12, increasing the connection area between the first bolt 4 and the connecting plates 12. The two connecting plates 12 are located at both ends of the first bolt 4, providing effective support for the first bolt 4 and preventing deformation at the connection between the first bolt 4 and the connecting plates 12, thus improving the connection strength. At the same time, the supporting plate 33 on the beam-column connector 3 can support the bottom of the I-beam 2, increasing the load-bearing capacity of the I-beam 2 and preventing the I-beam 2 from easily detaching from the irregular steel column 1, making the connection more stable and reliable.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
