Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and more specifically, to steel beams for hoisting prefabricated buildings. Background Technology

[0002] Prefabricated construction refers to the process of prefabricating building components in a factory and then assembling them on site. This can improve efficiency, reduce construction time, and reduce environmental impact. Prefabricated hoisting steel beams are a key component in this process. If the construction site is limited by space and long steel beams are inconvenient to install, prefabricated steel beams will be used. Prefabricated construction can facilitate transportation and rapid building construction.

[0003] A search revealed that Chinese patent CN214195005U discloses "a prefabricated building hoisting steel beam, including a connecting mechanism, with steel beams on both sides of the connecting mechanism, and connecting plates at two opposite ends of the two steel beams; the connecting mechanism includes two symmetrical fixing blocks, with multiple linearly and equally spaced connecting holes near both sides of the fixing blocks; this prefabricated building hoisting steel beam, through the provided connecting mechanism, namely, with the cooperation of fixing holes, fixing plates, baffles, bolts and nuts, etc., on the one hand, the connecting mechanism plays a stable connection role between the two steel beams, which facilitates better support performance of the steel beams and improves the structural strength and safety of the steel beams; on the other hand, the setting of the first bolt, first nut, second bolt and second nut, etc., facilitates rapid installation between the steel beams and facilitates rapid connection of the two steel beam sections," but it still has the following defects:

[0004] (1) In practical applications, the connection mechanism only reinforces the joint between steel beams, while the middle area of ​​the steel beam lacks a corresponding support structure. This forces the middle part of the steel beam to bear a greater pressure load, which in turn leads to a shortened service life.

[0005] (2) In actual operation, due to the lack of matching lifting devices, the steel beam is not stable enough during the lifting process, resulting in unstable phenomena such as swaying, which creates safety hazards. This unstable lifting method also has an adverse effect on the service life of the steel beam, accelerating its wear and aging process.

[0006] Therefore, we made improvements and proposed prefabricated building hoisting steel beams. Utility Model Content

[0007] The purpose of this utility model is to address the problem that in current applications, reinforcement is only applied at the connection points between steel beams, resulting in a lack of support in the middle of the steel beams. This causes the middle of the steel beams to bear greater pressure, leading to a reduced service life. Furthermore, the lack of a matching lifting device results in unstable lifting and potential safety hazards.

[0034] like Figure 1-5 As shown, this embodiment proposes a prefabricated building hoisting steel beam, including a steel beam 1, a connecting support assembly 2 on the steel beam 1, and a hoisting assembly 3 on the steel beam 1;

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the connecting support assembly 2 includes an I-beam wrapping block 201, a fixing plate 202, a first fixing hole 203, a second fixing hole 204, a first bolt 205, and a first nut 206. The I-beam wrapping block 201 is snapped onto one end of the steel beam 1. The two fixing plates 202 are snapped onto the top and bottom of the I-beam wrapping block 201, respectively, and are located at the top and bottom of the steel beam 1. The four first fixing holes 203 are opened on the fixing plate 202 and penetrate through the fixing plate 202, the I-beam wrapping block 201, and the steel beam 1. The four second fixing holes 204 are opened on the fixing plate 202 and penetrate through the fixing plate 202 and the steel beam 1. The first bolt 205 is bolted into the interior of the first fixing hole 203 and the second fixing hole 204. The first nut 206 is bolted onto the periphery of the first bolt 205. In use, the two steel beams 1 are joined and wrapped by the I-beam wrapping block 201 to stabilize the connection between the steel beams 1. The extension of the fixing plate 202 can expand the support surface of the two steel beams 1, making the steel beams 1 more evenly stressed. The I-beam wrapping block 201 and the fixing plate 202 are fixed by the first bolt 205 and the first nut 206, thereby increasing the support force of the steel beams 1 to the outside world and improving the service life of the steel beams 1.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, the lifting assembly 3 includes C-shaped plates 301, support holes 302, support columns 303, support plates 304, adjusting blocks 305, extension blocks 306, and hooks 307.

The support column 303 is threaded into the support holes 302. The support plate 304 is fixedly connected to the bottom of the support column 303. The adjusting block 305 is fixedly connected to the top of the support column 303. Two extension blocks 306 are welded to both sides of the C-shaped plates 301. The hooks 307 are welded to the top of the extension blocks 306. In use, the two C-shaped plates 301 are snapped onto the steel beam 1. The support column 303 is threaded to allow the support plate 304 to fit snugly against the steel beam 1 for fixation. The four hooks 307 are extended by the extension blocks 306, making the lifting of the steel beam 1 more stable and reducing potential hazards.

[0037] like Figure 3 and Figure 4As shown, two side plates 4 are snapped onto one side of the I-beam wrapping block 201, one on each side of the block. The side plates 4 are located on both sides of the steel beam 1. Four third fixing holes 5 are provided on each side plate 4, penetrating the side plate 4, the I-beam wrapping block 201, and the steel beam 1. Second bolts 6 are bolted into the interior of each third fixing hole 5, and second nuts 7 are bolted to the periphery of each second bolt 6. In use, the side plates 4 are fixed using the second bolts 6 and the second nuts 7, thus supporting the side of the steel beam 1 and enhancing stability and service life.

These threaded holes 13 work together, and a fourth bolt 14 is bolted into each threaded hole 13. A fourth nut 15 is bolted to the periphery of the fourth bolt 14. In use, the two stabilizing plates 12 work together to provide stable support between the two C-shaped plates 301, increasing stability during lifting. The distance between the two C-shaped plates 301 can be increased or decreased through the threaded holes 13 on the stabilizing plates 12, allowing for flexible lifting.

[0040] like Figure 3 and Figure 4 As shown, a reinforcing plate 16 is snapped onto one side of each of the two side plates 4. The reinforcing plate 16 has four fifth fixing holes 17 that penetrate the reinforcing plate 16, the side plates 4, and the steel beam 1. Fifth bolts 18 are bolted into the interior of each fifth fixing hole 17, and fifth nuts 19 are bolted to the periphery of each fifth bolt 18. In use, the reinforcing plates 16 connect the assembled side plates 4, strengthening the overall structure, allowing for more even pressure distribution, and increasing the service life of the steel beam 1.

[0041] like Figure 3As shown, the top and bottom of the steel beam 1 are provided with eight locking slots 20, which are evenly distributed on the top and bottom of the steel beam 1. A locking plate 21 is locked into each locking slot 20. The locking plate 21 is used in conjunction with the side plate 4, and one end of the locking plate 21 is welded to the side plate 4. In use, the locking plate 21 locks the side plate 4 and the steel beam 1 in place, effectively preventing the side plate 4 from shifting and reducing potential safety hazards.

[0042] Specifically, when using the prefabricated building hoisting steel beams: Through the set connecting support assembly 2, two steel beams 1 are joined and wrapped by the I-beam wrapping block 201, stabilizing the connection between the steel beams 1. The extension of the fixing plate 202 expands the support surface for the two steel beams 1, making the force on the steel beams 1 more even. The I-beam wrapping block 201 and the fixing plate 202 are fixed by the first bolt 205 and the first nut 206, thereby increasing the support force of the steel beams 1 to the outside world and improving the service life of the steel beams 1. Two C-shaped plates 301 are snapped onto the steel beams 1, and the support plate 304 is fixed tightly against the steel beams 1 by the threaded movement of the support column 303. The extension block 306 extends and four hooks 307 are installed, making the steel beams 1 more stable when hoisted and reducing potential hazards. The side plate 4 is fixed by the second bolt 6 and the second nut 7, and the side plate 4 supports the side of the steel beams 1, enhancing stability and service life.
