Description

Technical Field

[0001] This utility model relates to the field of steel structure enclosure technology, and specifically to a non-destructive connection device for steel structure enclosure. Background Technology

[0002] Sealing openings typically involves welding, which requires professional welders. Hot work poses safety hazards, and corrosion protection is necessary after welding. This process has a long construction period and is prone to quality problems such as insufficient weld length and incomplete welds. Furthermore, welding makes disassembly difficult, requiring cutting for temporary sealing, which can affect the integrity and original performance of the components. In addition, welding operations can easily cause fires, increasing the probability of safety accidents and raising safety risks. Utility Model Content

[0003] To address the technical problems in the existing technology, this utility model provides a non-destructive connection device for steel structure enclosure. It can achieve high-strength enclosure and convenient protection of steel structure projects by using non-destructive mechanical connection components during steel structure enclosure. It avoids the damage to the original performance and appearance of the steel structure caused by traditional welding processes, and completes the enclosure of steel structure openings while protecting the integrity and original performance of the steel structure. This saves manpower, time and effort, and improves installation efficiency.

[0004] The technical solution includes a connecting component, a main keel, and secondary keels. The main keel is detachably connected to the secondary steel beam via the connecting component. Multiple secondary keels are bolted between adjacent main keels, and these secondary keels are spaced apart along the length of the main keel. The connecting component includes a steel plate, a column assembly, and a U-shaped clip. The bottom of the main keel is detachably connected to the top of the column assembly via bolts. The bottom of the column assembly is welded to the steel plate. The steel plate is detachably connected to the secondary steel beam via the U-shaped clip.

[0005] Furthermore, the connection point between the U-shaped clip and the secondary steel beam is located on the side closer to the main steel beam.

[0006] Furthermore, the length direction of the main keel is the same as the length direction of the main steel beam.

[0007] Furthermore, the column assembly includes a sleeve, a rod, and pin plates. The top end of the sleeve is detachably connected to the main keel by bolts, and the bottom end of the sleeve is slidably sleeved with the rod. The end of the rod away from the sleeve is welded to the steel plate. The sleeve and the rod are respectively provided with a first strip hole and a second strip hole arranged horizontally. The height of the first strip hole and the second strip hole is greater than the thickness of at least two pin plates. The pin plates are installed in the first strip hole and the second strip hole, and both ends of the pin plates extend out of the sleeve.

[0008] Furthermore, the sleeve rod is provided with a plurality of second strip holes spaced apart along its length direction, and under the action of the pin plate, the first strip holes cooperate with different second strip holes.

[0009] Furthermore, a non-destructive connection device for steel structure enclosure also includes an enclosure plate, which is fixedly installed on the multiple secondary keels by self-tapping screws.

[0010] Beneficial effects:

[0011] 1. In this utility model, the setting of connecting components, main keel and secondary keel can realize high-strength enclosure and convenient protection of steel structure engineering, avoid welding, drilling and other processes, ensure the integrity and original performance of components, reduce environmental pollution, and reduce the safety risks of on-site installation for workers. Combined with the setting of steel plates, column rods and U-shaped clips, modular design and assembly can be realized, which is convenient for disassembly and assembly, can be reused, and saves installation time and cost.

[0012] 2. In this utility model, the connection position of the U-shaped clip to the secondary steel beam is located on the side close to the main steel beam, which can improve the structural strength and increase the load-bearing capacity of the device.

[0013] 3. In this utility model, the height between the main keel and the secondary steel beam can be adjusted by setting up a sleeve, a rod, a pin plate, a first strip hole, and a second strip hole to meet the corresponding design height requirements. In specific use, the vertical height can be adjusted by installing different numbers of pin plates. At the same time, installing multiple pin plates can further increase the load-bearing capacity of the device. The setting of multiple second strip holes can improve the adjustment range. Specifically, when the number of pin plates that match a certain second strip hole with the first strip hole cannot meet the design height requirements, the first strip hole can be switched to match the previous or next second strip hole. At this time, the number of pin plates used can be appropriately increased to ensure structural strength.

[0014] 4. In this utility model, the setting of the sealing plate can prevent debris from falling into the opening and at the same time facilitate the passage of workers. Attached Figure Description

[0027] This utility model provides a non-destructive connection device for steel structure enclosure, such as... Figure 1 , Figure 2 and Figure 3As shown, the structure includes a connecting assembly, a main keel 1, and secondary keels 2. The main keel 1 is detachably connected to the secondary steel beam 3 via the connecting assembly. Both the main keel 1 and the secondary keel 2 are rectangular tubes with dimensions of 100mm×200mm×4mm and 50mm×100mm×3mm, respectively. The length direction of the main keel 1 is the same as that of the main steel beam 7. Multiple secondary keels 2 are bolted between adjacent main keels 1, and these secondary keels 2 are spaced apart along the length direction of the main keel 1. The connecting assembly includes a steel plate 4, a column rod assembly 5, and a U-shaped clip 6. The steel plate 4 has dimensions of 300mm×300mm×16mm, and the U-shaped clip 6 is M16. The bottom of the main keel 1 is detachably connected to the top of the column rod assembly 5 via bolts. The bottom of the column rod assembly 5 is welded to the steel plate 4. The steel plate 4 is detachably connected to the secondary steel beam 3 via the U-shaped clip 6.

[0028] In this embodiment, the connection components, main keel 1 and secondary keel 2 enable high-strength enclosure and convenient protection of steel structure engineering, avoid welding, drilling and other processes, ensure the integrity and original performance of components, reduce environmental pollution, and reduce the safety risks of on-site installation for workers. Combined with the steel plate 4, column rod group 5 and U-shaped clip 6, modular design and assembly can be realized, which is convenient to disassemble and reuse, saving installation time and cost.

[0029] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the connection point between the U-shaped clip 6 and the secondary steel beam 3 is located on the side close to the main steel beam 7.

[0030] In this embodiment, the connection between the U-shaped clip 6 and the secondary steel beam 3 is located on the side close to the main steel beam 7, which can improve the structural strength and increase the load-bearing capacity of the device.

[0031] In this utility model, preferably, such as Figure 1 and Figure 3As shown, the column assembly 5 includes a sleeve 51, a sleeve rod 52, and a pin plate 53. The top end of the sleeve 51 is detachably connected to the main keel 1 by bolts. The sleeve 51 is a rectangular tube with dimensions of 100mm × 200mm × 4mm. The bottom end of the sleeve 51 is slidably sleeved with the sleeve rod 52. The end of the sleeve rod 52 away from the sleeve 51 is welded to the steel plate 4. The sleeve 51 and the sleeve rod 52 are respectively provided with a first strip hole 8 and a second strip hole 9 arranged horizontally. The height of the first strip hole 8 and the second strip hole 9 is greater than the thickness of at least two pin plates 53. The pin plates 53 are installed in the first strip hole 8 and the second strip hole 9, and both ends of the pin plates 53 extend out of the sleeve 51. During on-site installation, the number of pin plates 53 installed at different positions can be used to ensure that the tops of multiple main keels 1 are on the same horizontal plane.

[0032] In this embodiment, the height between the main keel 1 and the secondary steel beam 3 can be adjusted by setting the sleeve 51, sleeve rod 52, pin plate 53, first strip hole 8 and second strip hole 9 to meet the corresponding design height requirements. In actual use, the vertical height can be adjusted by installing different numbers of pin plates 53. At the same time, the load-bearing capacity of the device can be further increased by installing multiple pin plates 53.
