Description

Technical Field

[0001] This invention relates to the field of steel structures, and in particular to a segmented steel beam structure. Background Technology

[0002] Steel beams are important components in building structures. They are usually horizontally installed and made of steel. They have high strength and can effectively bear lateral loads and transfer vertical loads to supporting structures such as main beams. In steel structure engineering, steel beams usually need to work together with I-beams to build a stable spatial structural system, which ensures the overall stability and safety of the building. They are widely used in various industrial and civil buildings.

[0003] In existing technologies, it has been found that most steel beams available on the market adopt an integrated structure. This structure ensures the overall strength to a certain extent. However, in actual construction, due to the large size and heavy weight of the integrated steel beams, transportation becomes extremely difficult, and construction efficiency is also low. In addition, during later maintenance, if any part of the integrated structure is damaged, the entire steel beam often needs to be replaced or extensively repaired, making maintenance difficult. Summary of the Invention

[0007] By adopting the above technical solution, the main body of the steel beam is divided into four sections, arranged from left to right as the starting section, the first intermediate section, the second intermediate section, and the ending section. A second interlocking part is provided at the right end of the starting section, the first intermediate section, and the second intermediate section, and a first interlocking part is provided at the left end of the first intermediate section, the second intermediate section, and the ending section. Each of the starting section, the first intermediate section, the second intermediate section, and the ending section has a groove at one end that fits into the first interlocking part and the second interlocking part. When the operator needs to assemble the starting section, the first intermediate section, the second intermediate section, and the ending section into a complete steel beam, the first interlocking part is connected to the corresponding second interlocking part through the grooves at the corresponding positions. The mechanical interlocking provides strong connection force for the splicing of the main body of the steel beam, ensuring that the various segmented components will not separate under load. During splicing, by setting the first connecting component and the second connecting component at the corresponding splicing positions of the starting section, the first intermediate section, the second intermediate section and the end section, the starting section, the first intermediate section, the second intermediate section and the end section can be spliced ​​into an integral main body of the steel beam. This application divides the main body of the steel beam into the starting section, the first intermediate section, the second intermediate section and the end section, and uses the first connecting component and the second connecting component to splice and cooperate with mechanical interlocking to improve the connection strength. It abandons the traditional integrated structure, which not only improves construction efficiency and reduces the difficulty of transporting individual parts, but also facilitates later maintenance.

[0008] Preferably, each of the first connecting components includes a first connecting plate, a second connecting plate, and two fixing bolts, and each of the first connecting plates is fitted with the corresponding second connecting plate.

[0009] By adopting the above technical solution, a first connecting plate, a second connecting plate, and fixing bolts are set to form an integral first connecting assembly. The first connecting plate and the second connecting plate have the same shape and position, so the first connecting plate can fit together with the second connecting plate.

[0010] Preferably, the side of each first connecting plate that is close to each other is fixedly connected to the front and back of the corresponding starting segment, first intermediate segment and second intermediate segment, and the side of each second connecting plate that is close to each other is fixedly connected to the front and back of the corresponding first intermediate segment, second intermediate segment and end segment, and two first mounting holes are opened at corresponding positions on the upper surface of each first connecting plate and second connecting plate.

[0011] By adopting the above technical solution, the front and back sides of the starting segment, the first intermediate segment, and the second intermediate segment are fixed to the corresponding first connecting plate, and the front and back sides of the first intermediate segment, the second intermediate segment, and the end segment are fixed to the corresponding second connecting plate. When the starting segment, the first intermediate segment, the second intermediate segment, and the end segment are connected to each other, the first connecting plate and the second connecting plate at the corresponding end positions can fit together. Two first mounting holes are opened on the upper surfaces of the first connecting plate and the second connecting plate, and the positions of the first mounting holes on the first connecting plate and the second connecting plate are corresponding.

[0012] Preferably, each fixing bolt passes through the corresponding first mounting hole to fix the corresponding first connecting plate and second connecting plate;

[0013] By adopting the above technical solution, after the fixing bolt passes through the corresponding first mounting hole, it is self-locked by its own nut and washer, thereby connecting the corresponding first connecting plate and second connecting plate, and then fixing the corresponding ends of the starting section, the first intermediate section, the second intermediate section and the end section, thus completing the splicing of the starting section, the first intermediate section, the second intermediate section and the end section.

[0014] Preferably, each of the second connecting components includes two connecting ribs, the outer surface of each connecting rib is fixedly connected to the outer surface of the corresponding starting segment, first intermediate segment, second intermediate segment and end segment, and a first double-ended bolt is fixedly installed between each two adjacent connecting ribs;

[0015] By adopting the above technical solution, connecting ribs are set to be fixed to the corresponding starting segment, first intermediate segment, second intermediate segment, and end segment. Each connecting rib has two connecting holes on its surface, and the positions of the connecting holes of the corresponding connecting ribs are corresponding. The first double-ended bolt passes through the connecting holes of the corresponding connecting rib and completes self-locking through the nut and washer of the first double-ended bolt itself, thereby fixing the corresponding connecting rib. Since the connecting rib is fixed to the corresponding starting segment, first intermediate segment, second intermediate segment, and end segment, the setting of the second connecting assembly can further improve the docking strength between the starting segment, first intermediate segment, second intermediate segment, and end segment.

[0016] Preferably, two first reinforcing ribs are fixedly connected to the front and back of both the first and second intermediate sections;

[0017] By adopting the above technical solution, two first reinforcing ribs are installed on the front and back of the first and second intermediate sections. The setting of the first reinforcing ribs can improve the overall structural strength of the intermediate sections and enhance their resistance to deformation.

[0018] Preferably, the steel beam body is provided with I-beam main beams on both the left and right sides, each I-beam main beam includes an I-beam body, and each I-beam body has second reinforcing ribs arranged at equal intervals fixedly connected to the left and right sides of the left and right sides.

[0019] By adopting the above technical solution, the I-beam main beam is set on the left and right sides of the steel crossbeam body, the I-beam body is set as the main body of the I-beam main beam, and the second reinforcing ribs are installed on the left and right sides of the I-beam body to improve the deformation resistance of the overall I-beam body.

[0020] Preferably, each of the I-beam bodies is provided with two connectors on the left and right sides, and two third reinforcing ribs are fixedly connected to the outer surface of each connector;

[0021] By adopting the above technical solution, two connectors are set on the left and right sides of the main body of the I-beam, and two third reinforcing ribs are installed on the outer surface of the connectors, so that the third reinforcing ribs can support the bending parts of the connectors, thereby improving the overall deformation resistance of the connectors.

[0022] Preferably, each of the I-beam bodies and connectors has a second mounting hole arranged at equal intervals at corresponding positions on the side close to each other. The left and right ends of the steel beam body are provided with second double-ended bolts and third double-ended bolts arranged at equal intervals. Each second double-ended bolt passes through the corresponding second mounting hole and fixes the corresponding I-beam body and connector.

[0023] By adopting the above technical solution, equidistant second mounting holes are opened on the side of the I-beam body and the connector that are close to each other, and the second mounting holes on the I-beam body correspond to the second mounting holes on the connector. The second double-ended bolts and the third double-ended bolts are set at the left and right ends of the steel beam body, and the second double-ended bolts are adapted to the corresponding second mounting holes so that the second double-ended bolts can pass through the second mounting holes. During installation, the connector is fitted to the I-beam body, and then the second double-ended bolts are passed through the corresponding second mounting holes, and self-locking is achieved by its own nut and washer, thereby completing the fixation of the connector.

When it is necessary to install the starting and ending sections on the main body of the I-beam, the ends of the starting and ending sections are fitted with the corresponding main body of the I-beam. At this time, the connecting part is located between the connecting parts. Since the connecting part and the connecting parts have corresponding third mounting holes, the operator can move the third double-headed bolt through the corresponding third mounting hole and complete the self-locking through its own nut and washer, thereby completing the fixing of the connecting part, so that the left and right ends of the main body of the steel beam can be connected and fixed with the main beam of the I-beam.

[0026] Beneficial effects

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] This invention provides a segmented steel beam structure, which divides the main body of the steel beam into four segments. During splicing, the first interlocking part and the second interlocking part at the end of each segment are engaged. Then, the starting segment, the first intermediate segment, the second intermediate segment and the ending segment are connected by the first connecting component and the second connecting component to complete the splicing of the main body of the steel beam. This application divides the main body of the steel beam into the starting segment, the first intermediate segment, the second intermediate segment and the ending segment, and uses the first connecting component and the second connecting component to splice and cooperate with mechanical interlocking to improve the connection strength. It abandons the traditional one-piece structure, which not only reduces the difficulty of transporting individual parts and improves construction efficiency, but also facilitates later maintenance.

[0029] This invention provides a segmented steel beam structure. By setting components such as a first connecting plate, a second connecting plate, connecting ribs, and a first double-ended bolt, during assembly, the starting segment, the first intermediate segment, the second intermediate segment, and the end segment are placed correspondingly until the first and second interlocking parts engage. At this point, the first connecting plate and the second connecting plate are in contact. Then, the operator inserts a fixing bolt through the corresponding first mounting hole, and self-locking is achieved through its own nut and washer. The connecting ribs are now positioned accordingly. The operator then moves the first double-ended bolt through the corresponding connecting rib, and self-locking is achieved through its own nut and washer, thus completing the assembly of the starting segment, the first intermediate segment, the second intermediate segment, and the end segment. After assembly, the mutual contact of the first and second connecting plates, along with the connecting ribs on the surfaces of the starting segment, the first intermediate segment, the second intermediate segment, and the end segment, enhances the connection strength of the assembly, improves the deformation resistance of the assembly, and avoids insufficient assembly strength.

[0030] This invention provides a segmented steel beam structure. By incorporating connectors, a third reinforcing rib, second double-ended bolts, and third double-ended bolts, when connecting the main body of the steel beam to the I-beam bodies on both sides, the connectors are first installed on the I-beam bodies. The second mounting holes on the I-beam bodies are aligned with the second mounting holes on the connectors. Then, the second double-ended bolts are passed through the corresponding second mounting holes and self-locked by their built-in nuts and washers. The starting and ending segments are then moved, causing the connecting parts to move and position themselves between the corresponding connectors until the third mounting holes on the connecting parts align with the third mounting holes on the connectors. Finally, the third double-ended bolts are passed through the corresponding third mounting holes and self-locked by their built-in nuts and washers. The connection between the I-beam body and the steel beam body is completed by the second and third double-ended bolts. The connectors and the third reinforcing rib enhance the connection strength at the joint, ensuring reliable connection. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.

[0041] Example 1: A segmented steel beam structure, referring to... Figure 1 , Figure 2 and Figure 4 The system includes a steel beam body 1, which comprises a starting section 101. On the right side of the starting section 101 are a first intermediate section 102, a second intermediate section 103, and an end section 104 arranged sequentially. A second engaging part 107 is fixedly connected to the right ends of the starting section 101, the first intermediate section 102, and the second intermediate section 103. A first engaging part 106 is fixedly connected to the left ends of the first intermediate section 102, the second intermediate section 103, and the end section 104. Each first engaging part 106 mechanically engages with a corresponding second engaging part 107, dividing the steel beam body 1 into four sections arranged from left to right: the starting section 101, the first intermediate section 102, the second intermediate section 103, and the end section 104. A second engaging part 107 is provided at the right ends of the starting section 101, the first intermediate section 102, and the second intermediate section 103. The first interlocking part 107 is provided, and the second interlocking part 106 is provided at the left end of the first intermediate section 102, the second intermediate section 103 and the end section 104. The first interlocking part 106 and the second interlocking part 107 are provided at the ends of the starting section 101, the first intermediate section 102, the second intermediate section 103 and the end section 104 that are in contact with each other. When the operator needs to splice the starting section 101, the first intermediate section 102, the second intermediate section 103 and the end section 104 into an integral steel beam body 1, the first interlocking part 106 and the corresponding second interlocking part 107 are connected through the grooves at the corresponding positions. Through the mechanical interlocking of the first interlocking part 106 and the second interlocking part 107, a strong connection force can be provided for the splicing of the steel beam body 1, ensuring that the various segment components will not separate when bearing load.

[0042] Reference Figure 1 , Figure 2 and Figure 4 Four first connecting components 2 are provided at the adjacent parts of the starting segment 101, the first intermediate segment 102, the second intermediate segment 103, and the end segment 104, and two second connecting components 3 are provided at the adjacent parts of the starting segment 101, the first intermediate segment 102, the second intermediate segment 103, and the end segment 104. By setting the first connecting components 2 and the second connecting components 3 at the corresponding splicing positions of the starting segment 101, the first intermediate segment 102, the second intermediate segment 103, and the end segment 104, the starting segment 101, the first intermediate segment 102, the second intermediate segment 103, and the end segment 104 can be spliced ​​into an integral steel beam body 1. This application divides the steel beam body 1 into the starting segment 101, the first intermediate segment 102, the second intermediate segment 103, and the end segment 104, and splices them together with the first connecting components 2 and the second connecting components 3 to improve the connection strength through mechanical interlocking. This abandons the traditional integrated structure, which not only improves construction efficiency and reduces the difficulty of transporting individual parts, but also facilitates later maintenance.

Each first connecting plate 201 is fitted with a corresponding second connecting plate 202. The first connecting plate 201, the second connecting plate 202, and the fixing bolts 203 form an integral first connecting assembly 2. The first connecting plate 201 and the second connecting plate 202 have the same shape and position, so the first connecting plate 201 can fit against the second connecting plate 202. The side of each first connecting plate 201 that is close to each other is fitted with the corresponding starting plate. The front and back sides of segment 101, the first intermediate segment 102, and the second intermediate segment 103 are fixedly connected. The side of each second connecting plate 202 that is close to each other is fixedly connected to the front and back sides of the corresponding first intermediate segment 102, second intermediate segment 103, and end segment 104. Two first mounting holes 204 are provided at corresponding positions on the upper surface of each first connecting plate 201 and second connecting plate 202 to fix the front and back sides of the starting segment 101, the first intermediate segment 102, and the second intermediate segment 103 to the corresponding first connecting plate 201, and to fix the first intermediate segment 101... 2. The front and back sides of the second intermediate section 103 and the end section 104 are fixed to the corresponding second connecting plates 202. When the starting section 101, the first intermediate section 102, the second intermediate section 103, and the end section 104 are aligned, the first connecting plates 201 and the second connecting plates 202 at the corresponding end positions can fit together. Two first mounting holes 204 are opened on the upper surfaces of the first connecting plates 201 and the second connecting plates 202, and the positions of the first mounting holes 204 on the first connecting plates 201 and the second connecting plates 202 are corresponding. Each fixing bolt 203 penetrates through... After passing through the corresponding first mounting hole 204, the corresponding first connecting plate 201 and second connecting plate 202 are fixed. After passing through the corresponding first mounting hole 204, the fixing bolt 203 is self-locked by its own nut and washer, thereby connecting the corresponding first connecting plate 201 and second connecting plate 202. This allows the corresponding ends of the starting segment 101, the first intermediate segment 102, the second intermediate segment 103 and the ending segment 104 to be fixed, thus completing the splicing of the starting segment 101, the first intermediate segment 102, the second intermediate segment 103 and the ending segment 104.

[0044] Reference Figure 2 , Figure 4 and Figure 5Each second connecting component 3 includes two connecting ribs 301. The outer surface of each connecting rib 301 is fixedly connected to the outer surface of the corresponding starting segment 101, first intermediate segment 102, second intermediate segment 103, and end segment 104. A first double-ended bolt 302 is fixedly installed between each pair of adjacent connecting ribs 301. The connecting ribs 301 are fixed to the corresponding starting segment 101, first intermediate segment 102, second intermediate segment 103, and end segment 104. Each connecting rib 301 has two connecting holes on its surface, which are corresponding to the connecting... The connecting holes of the rib plate 301 are positioned correspondingly. The first double-ended bolt 302 passes through the connecting hole on the corresponding connecting rib plate 301 and is self-locked by the nut and washer that come with the first double-ended bolt 302, thereby fixing the corresponding connecting rib plate 301. Since the connecting rib plate 301 is fixed to the corresponding starting segment 101, first intermediate segment 102, second intermediate segment 103 and end segment 104, the setting of the second connecting component 3 can further improve the docking strength between the starting segment 101, first intermediate segment 102, second intermediate segment 103 and end segment 104.

[0045] Reference Figure 2 , Figure 4 and Figure 5 Two first reinforcing ribs 108 are fixedly connected to the front and back of the first intermediate section 102 and the second intermediate section 103. The installation of the two first reinforcing ribs 108 on the front and back of the first intermediate section 102 and the second intermediate section 103 can improve the overall structural strength of the intermediate section and enhance its resistance to deformation.

[0046] Example 2: A segmented steel beam structure, referring to... Figure 3 , Figure 6 and Figure 7 The steel beam body 1 has I-beams 4 on both the left and right sides. Each I-beam 4 includes an I-beam body 401. The left and right sides of each I-beam body 401 are fixedly connected with second reinforcing ribs 402 arranged at equal intervals. The I-beams 4 are set on the left and right sides of the steel beam body 1. The I-beam body 401 is set as the main body of the I-beam 4. The second reinforcing ribs 402 are installed on the left and right sides of the I-beam body 401. The deformation resistance of the overall I-beam body 401 is improved by the second reinforcing ribs 402.

[0047] Reference Figure 6 , Figure 7 and Figure 8Two connectors 5 are provided on the left and right sides of each I-beam body 401. Two third reinforcing ribs 6 are fixedly connected to the outer surface of each connector 5. The two connectors 5 are provided on the left and right sides of the I-beam body 401, and two third reinforcing ribs 6 are installed on the outer surface of the connectors 5 so that the third reinforcing ribs 6 can support the bending parts of the connectors 5, thereby improving the overall deformation resistance of the connectors 5.

[0048] Reference Figure 6 , Figure 7 and Figure 8 Each I-beam body 401 and connector 5 has equally spaced second mounting holes 7 on corresponding positions on their adjacent sides. The left and right ends of the steel crossbeam body 1 are each provided with equally spaced second double-ended bolts 8 and equally spaced third double-ended bolts 10. Each second double-ended bolt 8 passes through the corresponding second mounting hole 7 to fix the corresponding I-beam body 401 and connector 5. Equally spaced second mounting holes 7 are provided on the adjacent sides of the I-beam body 401 and connector 5. The second mounting hole 7 on the 1 corresponds to the second mounting hole 7 on the connector 5. The second double-ended bolt 8 and the third double-ended bolt 10 are set at the left and right ends of the steel beam body 1. The second double-ended bolt 8 is adapted to the corresponding second mounting hole 7 so that the second double-ended bolt 8 can pass through the second mounting hole 7. During installation, the connector 5 is attached to the I-beam body 401, and then the second double-ended bolt 8 passes through the corresponding second mounting hole 7. It is self-locked by its own nut and washer, thereby completing the fixation of the connector 5.

[0049] Reference Figure 5 , Figure 7 and Figure 8Both the starting segment 101 and the ending segment 104, located at their far ends, are fixedly connected to connecting parts 105. Each connecting part 105 is located between corresponding connecting pieces 5. Each connecting part 105 and each connecting piece 5, on their adjacent sides, has equidistantly arranged third mounting holes 9. Each third double-ended bolt 10 passes through the corresponding third mounting hole 9 to fix the corresponding connecting part 105 and connecting piece 5. Connecting parts 105 are installed at the far ends of the starting segment 101 and the ending segment 104, and are positioned between corresponding connecting pieces 5. When it is necessary to... When the starting section 101 and the ending section 104 are installed on the I-beam body 401, the ends of the starting section 101 and the ending section 104 are fitted with the corresponding I-beam body 401. At this time, the connecting part 105 is located between the connecting parts 5. Since the connecting part 105 and the connecting parts 5 have corresponding third mounting holes 9, the operator can move the third double-headed bolt 10 through the corresponding third mounting hole 9 and complete the self-locking through its own nut and washer, thereby completing the fixation of the connecting part 105, so that the left and right ends of the steel beam body 1 can be connected and fixed with the I-beam main beam 4.

[0050] The implementation principle of this application embodiment is as follows: the main body 1 of the steel beam is divided into four sections: the starting section 101, the first intermediate section 102, the second intermediate section 103, and the ending section 104. By segmenting the sections, the difficulty of transporting a single piece is reduced. When the main body 1 of the steel beam is transported to the construction site, firstly, the connecting piece 5 is moved and placed on both sides of the main body 401 of the I-beam. The second mounting hole 7 on the main body 401 of the I-beam is aligned with the second mounting hole 7 on the connecting piece 5. Then, the second double-ended bolt 8 is connected to the second mounting hole 7, and the connection is completed by the self-locking of the nut and washer that come with the second double-ended bolt 8. During the fixing and docking of component 5, the moving starting segment 101 and the ending segment 104 drive the connecting part 105 to move, positioning the connecting part 105 between the corresponding connecting components 5 until the third mounting hole 9 on the connecting part 105 aligns with the third mounting hole 9 on the connecting component 5. The connection is achieved by the third double-ended bolt 10 connecting to the third mounting hole 9, and by the self-locking of the nut and washer inherent in the third double-ended bolt 10, thus completing the docking between the I-beam body 401 and the starting segment 101 and the ending segment 104. After the first and last ends are docked, the first intermediate segment 102 is hoisted using hoisting equipment, and the second segment 104 is hoisted from the right end of the starting segment 101. The engagement portion 107 corresponds to the first engagement portion 106 at the left end of the first intermediate section 102, allowing them to engage. At this time, the first connecting plate 201 and the second connecting plate 202 are in contact with each other. Then, the operator connects the fixing bolt 203 to the first mounting hole 204, and uses the nut and washer of the fixing bolt 203 itself for self-locking, so that the first connecting plate 201 and the second connecting plate 202 can be fixed until the fixing bolt 203 at the mating part is installed. Then, the connecting rib plate 301 and the first double-ended bolt 302 are connected, and the nut and washer of the first double-ended bolt 302 itself for self-locking. The second intermediate section 103 is hoisted, and the above operation is repeated. The left and right ends of the second intermediate section 103 are connected to the right end of the first intermediate section 102 and the left end of the end section 104, respectively, thereby completing the splicing and hoisting of the main body 1 of the steel beam. The setting of the first connecting component 2 and the second connecting component 3 can improve the connection strength of each splicing part, improve the deformation resistance of the splicing part, and avoid insufficient splicing strength. The splicing and mechanical interlocking of the first connecting component 2 and the second connecting component 3 improves the connection strength, abandons the traditional one-piece structure, not only improves the construction efficiency, but also facilitates the later maintenance.
