[0021] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] Example 1 like Figures 1-3 As shown, a support device for a cantilevered fire corridor structure in this embodiment includes a horizontal brace beam 1, a first diagonal brace beam 2, a second diagonal brace beam 3, a threaded rod 4, a rotating column 5, a first guide rod 6, and a second guide rod 61. One end of the first diagonal brace beam 2 is hinged to the middle of the horizontal brace beam 1. One end of the threaded rod 4 is coaxially fixed to the rotating column 5, and the rotating column 5 is rotatably connected to the other end of the first diagonal brace beam 2. The other end of the threaded rod 4 is threadedly connected to the second diagonal brace beam 3. The first diagonal brace beam 2, the rotating column 5, the threaded rod 4, and the second diagonal brace beam 3 are arranged coaxially. The first guide rod 6 and the second guide rod 61 are fixed to both sides of the other end of the first diagonal brace beam 2, and the first guide rod 6 and the second guide rod 61 are arranged parallel to each other on both sides of the threaded rod 4. The opposite side walls of the second diagonal brace beam 3 are respectively provided with a first guide groove 31 and a second guide groove 32. The first guide rod 6 and the second guide rod 61 are slidably connected in the first guide groove 31 and the second guide groove 32 along the axial direction of the threaded rod 4.

[0023] like Figure 1 and Figure 2As shown, specifically, in this embodiment, the crossbeam 1 is an I-beam, and one end of the first diagonal brace 2 is hinged to one side wall of the I-beam.

[0024] In this embodiment, the support device for the cantilevered structure of the fire-fighting corridor can utilize the cross bracing beam 1 to support the fire-fighting corridor or cantilever structure. During use, the support angle can be adjusted by operating the rotating column 5 to drive the threaded rod, thereby improving the flexibility of the support.

[0025] The support device for the cantilevered structure of the fire corridor in this embodiment improves upon the existing support devices, which are mostly directly welded together and then supported during construction and installed on the wall with bolts. Such support devices are relatively fixed and inconvenient to adjust during use, and are not convenient or flexible enough when dealing with narrow spaces or long support distances.

[0026] Example 2 Based on Embodiment 1 or Embodiment 2, the surface of the rotating column 5 in this embodiment has a circular rotating notch 51 for wrench engagement. The rotating notch facilitates the operation of turning the rotating column.

[0027] Preferably, the cross-section of the rotating notch 51 is a regular hexagonal structure.

[0028] Example 3 Based on Embodiment 1 or Embodiment 2, in this embodiment, a first limiting protrusion 38 and a second limiting protrusion 39 are respectively provided on opposite side walls at one end of the second diagonal brace 3. The first limiting protrusion 38 is located inside one end of the first guide groove 31, and the second limiting protrusion 39 is located inside one end of the second guide groove 32. The free ends of the first guide rod 6 and the second guide rod 61 are respectively fixed with oppositely arranged first abutting protrusion 62 and second abutting protrusion 63, which can cooperate with the first limiting protrusion 38 and the second limiting protrusion 39 to limit movement. By setting the limiting protrusions and abutting protrusions, the first guide rod and the second guide rod are prevented from coming out of their corresponding guide grooves.

[0029] In this embodiment, the first guide rod 6 and the second guide rod 61 are slidably disposed in the corresponding first guide groove 31 and second guide groove 32, which can improve the stability of the expansion and contraction of the first and second diagonal bracing beams.

[0030] Example 4 Based on any of the above embodiments, in this embodiment, the side of the first guide groove 31 facing away from the second guide groove 32 is an open structure, and the side of the second guide groove 32 facing away from the first guide groove 31 is an open structure, which facilitates the assembly of the corresponding guide rod.

[0031] Specifically, the first guide rod 6 is flush with the opening of the first guide groove 31, and the second guide rod 61 is flush with the opening of the second guide groove 32, making the overall structure more standardized and more stable.

[0032] Example 5 Based on any of the above embodiments, in this embodiment, one end of the first diagonal brace 2 is hinged to the middle of the horizontal brace 1 via a first hinge shaft 21, one end of the horizontal brace 1 is vertically fixed with a first fixing plate 11, and the free end of the second diagonal brace 3 is hinged to a second fixing plate 34 via a second hinge shaft 33. By providing the first fixing plate and the second fixing plate, it is convenient to fix it to the wall or other structures.

[0033] Specifically, such as Figures 1-3 As shown, in this embodiment, the first hinge shaft 21 and the second hinge shaft 33 are arranged in parallel. The first hinge shaft 21 is arranged perpendicular to the cross brace beam 1. The first hinge shaft 21 is arranged in parallel to the first fixing plate 11. The first fixing plate 11 and the second fixing plate 34 are arranged in parallel.

[0034] Specifically, such as Figures 1-3 As shown, in this embodiment, one end of the first diagonal brace 2 is fixed with a first U-shaped hinge 22, and the middle of the cross brace 1 is fixed with a first hinge plate 12. The first hinge plate 12 is inserted into the first U-shaped hinge 22 and hinged through a first hinge shaft 21. The free end of the second diagonal brace 3 is fixed with a second U-shaped hinge 36, and a second hinge plate 35 is fixed on the second fixed plate 34. The second hinge plate 35 is inserted into the second U-shaped hinge 36 and hinged through a second hinge shaft 33.

[0035] like Figure 1 and Figure 2 As shown, specifically, both the first fixing plate 11 and the second fixing plate 34 are provided with connecting holes 37. The connecting holes facilitate the insertion of bolts, which are then tightened with nuts, thereby fixing the plate to the wall. The first fixing plate 11 and the second fixing plate 34 are preferably rectangular plates, and a connecting hole can be provided near each of the four corners of the rectangular plate.

[0036] This utility model provides a support device for fire-fighting corridors and cantilever structures. In use, bolts are inserted through the connecting holes on the first fixing plate and tightened with nuts. The diagonal bracing structure is then extended to a suitable angle. Based on the support distance of the diagonal bracing, an adjustable wrench is used to rotate the threaded rod inside the rotating notch, allowing the second diagonal bracing beam to extend outwards. After extending a suitable distance, the support angle of the diagonal bracing structure is adjusted via the hinge structure and the second fixing plate. Finally, bolts are inserted through the connecting holes on the second fixing plate to re-fix the diagonal bracing structure. This allows for convenient extension and rotation adjustment during use, improving flexibility and applicability in different construction environments.
