Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology and provides a large-span steel structure beam that reduces the difficulty of construction alignment and improves construction efficiency. Background Technology
[0002] Steel structural beams are the main load-bearing components of steel cable trays, responsible for lateral support and suspension of the bridge deck. They are widely used in construction, manufacturing, and other fields. In the construction industry, steel structural beams are typically used in the structures of large roofs, bridges, and buildings, serving to support important parts such as roofs, floors, and walls.
[0003] In existing steel structure beams, beams are often connected to each other using high-strength bolts and node plates. During the bolt connection construction of steel structure beams, workers need to use appropriate hoisting equipment to lift a single beam to the position where it is connected to another beam. Then, workers connect the two beams using high-strength bolts and node plates.
[0004] However, during the actual construction of the steel structure beam connection, the bolt holes on the beam are small and difficult to align. Furthermore, the beam is easily affected by external factors such as wind during hoisting, resulting in significant disturbances. This poses a considerable challenge to the workers in connecting the beams and seriously affects the overall construction efficiency of the steel structure beam connection.
[0005] In summary, existing steel structure beams suffer from high difficulty in alignment and low construction efficiency due to their inherent structure. Utility Model Content

[0012] The left end of the plug-in plate is inserted into the sliding cavity of one of the two adjacent crossbeams and is fixedly connected to the limiting magnetic plate located in the sliding cavity. A mounting magnetic block is fixed on the inner wall of the sliding cavity, and the mounting magnetic block is used to magnetically fix it to the limiting magnetic plate.
[0013] The right end of the plug-in plate is inserted into the plug-in cavity of the other crossbeam among the two adjacent crossbeams, and the plug-in plate is fixed to the other crossbeam as a whole by the positioning mechanism.

[0030] Two adjacent crossbeams 1 are connected as one unit at their beginning and end positions by a plug-in mechanism 6 located in the plug-in cavity 2 and the sliding cavity 3. The positioning mechanism 5 fixes the plug-in mechanism 6 to the crossbeam 1 where the plug-in mechanism 6 is located. In this embodiment, the plug-in mechanism 6 is slidably connected in the sliding cavity 3 beforehand, that is, the plug-in plate 601 described in the following embodiment is slidably connected in the sliding cavity 3 by a limiting magnetic plate 604.
[0031] To facilitate the manufacturing of the positioning mechanism 5 and ensure the stability of the connection between two adjacent crossbeams 1, in the above embodiment, preferably: the positioning mechanism 5 includes a sliding magnetic rod 501 passing through the positioning mechanism mounting cavity 4. A tension spring 502 is fitted on the sliding magnetic rod 501. The top end of the sliding magnetic rod 501 protrudes from the surface of the crossbeam 1 and is fixed integrally with the pull block 503. The tension spring 502 is limited and installed in the limiting cavity of the positioning mechanism mounting cavity 4. In this embodiment, the top end of the sliding magnetic rod 501 protruding from the surface of the crossbeam 1 means protruding from the upper or lower surface of the crossbeam 1, that is, the top surface of the upper longitudinal beam plate 7 of the crossbeam 1 or the bottom surface of the lower longitudinal beam plate 7 of the crossbeam 1 as described in the following embodiment.
[0032] To make the plug-in mechanism 6 easy to manufacture and to ensure the stability of the connection between two adjacent crossbeams 1, in the above embodiment, preferably: the plug-in mechanism 6 includes a plug-in plate 601, a positioning hole 602 on the top plate of the plug-in plate 601, and a fixing magnetic block 603 in the positioning hole 602.
[0033] The left end of the plug plate 601 is inserted into the sliding cavity 3 of one of the two adjacent crossbeams 1 and is fixedly connected to the limiting magnetic plate 604 located in the sliding cavity 3. A mounting magnetic block 605 is fixed on the inner wall of the sliding cavity 3. The mounting magnetic block 605 is used to magnetically fix with the limiting magnetic plate 604.
[0034] The right end of the insertion plate 601 is inserted into the insertion cavity 2 of another crossbeam 1 among two adjacent crossbeams 1, and the positioning mechanism 5 fixes the insertion plate 601 and the other crossbeam 1 together. In this embodiment, the limiting magnetic plate 604 is slidably connected in the sliding cavity 3; the mounting magnetic block 605 is located in the slot on the inner wall of the sliding cavity 3. The mounting magnetic block 605 can be embedded in the slot on the inner wall of the sliding cavity 3, or it can be fixed in the slot on the inner wall of the sliding cavity 3 by screws.
[0035] To facilitate the operation of the positioning mechanism 5 and to minimize the distance that construction personnel can pull out the pull block 503, in the above embodiment, preferably, the positioning hole 602 is located in the slide groove 606, which is located on the top plate of the plug-in plate 601.
[0036] To facilitate the fabrication of the crossbeam 1, in the above embodiment, preferably, the crossbeam 1 is made of I-beam steel, and the insertion cavity 2, sliding cavity 3 and positioning mechanism mounting cavity 4 are all located on the longitudinal beam plate 7.
[0037] In the above embodiments, all components are commercially available products.
[0038] The usage process of the structure described above is as follows: When constructing the large-span steel structure beam, the worker hoists the beam 1 to the installation position. The worker pulls out the insertion plate 601 from the first beam 1, and simultaneously lifts the pull block 503 on the second beam 1. Then, the insertion plate 601 pulled out from the first beam 1 is inserted into the insertion cavity 2 of the adjacent second beam 1. When the insertion plate 601 slides to the positioning hole 602, the fixed magnetic block 603 and the sliding magnetic rod 501 are magnetically attracted together under the magnetic force of the fixed magnetic block 603 and the sliding magnetic rod 501; at the same time, the limiting magnetic plate 604 and the installation magnetic block 605 are magnetically fixed together; thus, the first beam 1 and the second beam 1 are connected and fixed together. The above process is repeated to complete the construction of the large-span steel structure beam. The entire process facilitates stable alignment for construction workers during the actual connection of large-span steel structure beams, and avoids significant disturbance caused by wind swaying during hoisting of the beam body 1. Consequently, it reduces the difficulty for workers to connect the beam body 1, thereby improving the construction efficiency of large-span steel structure beams.
