[0025] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0026] Reference below Figure 1-Figure 2 The specific structure of the construction device for the cantilever roof according to the embodiment of the present invention is described.

[0027] It should be noted in advance that the intersection of the cross beam 200 and the longitudinal beam 300 on the cantilevered roof will hinder the operating platform 1 from continuously moving along the length direction of the cross beam 200 .

[0028] like Figure 1As shown, the present embodiment provides a construction device for a cantilever roof, which is arranged on a roof column 100. There are multiple roof columns 100, and the multiple roof columns 100 are distributed in a matrix. A crossbeam 200 is arranged between two adjacent roof columns 100 along a first direction of the multiple roof columns 100, and a longitudinal beam 300 is arranged between two adjacent roof columns 100 along a second direction. The construction device for the cantilever roof includes an operating platform 1, a connecting rod 2 and a driving member 3. The operating platform 1 is detachably connected to the connecting rod 2, and the connecting rod 2 is movably arranged on the cross beam 200, and the connecting rod 2 is detachably connected to the driving member 3; wherein the driving member 3 is configured to drive the connecting rod 2 to move along the length direction of the cross beam 200, thereby driving the operating platform 1 to move along the length direction of the cross beam 200.

[0029] It is understandable that, since the driving member 3 is configured to drive the connecting rod 2 to move along the length direction of the beam 200, thereby driving the operating platform 1 to move along the length direction of the beam 200, it is convenient for the operator on the operating platform 1 to sequentially install the metal aluminum edges along the length direction of the beam 200. In addition, since the operating platform 1 is detachably connected to the connecting rod 2, and the connecting rod 2 is detachably connected to the driving member 3, it can effectively solve the problem that the intersection of the beam 200 and the longitudinal beam 300 hinders the continued movement of the operating platform 1. The operating platform 1 and the connecting rod 2 can be reinstalled on other beams 200 to continue to install the metal aluminum edges. In summary, the construction device of the cantilever roof has a short construction period, low construction cost, high construction efficiency, simple operation and high safety.

[0030] It is particularly noted that the first direction is perpendicular to the second direction.

[0031] Alternatively, if Figure 2 As shown, the construction device for the cantilever roof also includes a guide assembly 4 , the cross beam 200 is an I-beam beam, the guide assembly 4 is connected to the connecting rod 2 , and the guide assembly 4 is located in the beam groove of the cross beam 200 .

[0032] It should be noted that the guide assembly 4 serves to guide the connecting rod 2 along the length direction of the cross beam 200 and to limit the position of the connecting rod 2 to prevent it from shaking left and right during movement, thereby affecting the quality of the metal aluminum edge installation by the operator. In addition, the I-beam structure of the cross beam 200 is fully utilized, and the beam groove on the I-beam serves as a slide rail, and the guide assembly 4 can move in the beam groove, which is ingeniously designed and saves construction costs.

[0033] Optionally, the guide assembly 4 includes a pulley, a support member and an axle body, the support member is connected to the connecting rod 2, the axle body is arranged on the support member, the pulley is rotatably passed through the axle body, and the connecting rod 2 can drive the pulley to move along the length direction of the beam 200.

[0034] It is understandable that if Figure 1As shown, the driving member 3 drives the connecting rod 2 to move along the length direction of the beam 200. Since the connecting rod 2 is connected to the support member, the pulley is rotatably provided on the shaft body on the support member. Therefore, when the connecting rod 2 moves along the length direction of the beam 200, the pulley continuously rolls in the beam groove, thereby playing a role in guiding the connecting rod 2.

[0035] Optionally, the driving member 3 is an electric hoist, which is detachably fixed to the longitudinal beam 300 and connected to the connecting rod 2 via a connecting wire 5. It is understandable that the electric hoist as the driving member 3 can effectively pull the connecting wire 5, thereby driving the connecting rod 2 to move along the length direction of the crossbeam 200. In other embodiments of the present invention, the driving member 3 can also be selected in other ways according to actual conditions, and is not limited to an electric hoist.

[0036] Optionally, the construction device of the cantilever roof further includes a hoist, which is arranged on the connecting rod 2 and is used to adjust the vertical distance between the operating platform 1 and the cross beam 200. It should be noted that after the operator installs the metal aluminum edge between the two longitudinal beams 300, the operating platform 1 needs to be disassembled. Since the hoist can adjust the vertical distance between the operating platform 1 and the cross beam 200, it is convenient to place the operating platform 1 on the roof panel and reinstall it on the next roof column 100 where the metal aluminum edge needs to be installed.

[0037] Optionally, the connecting rod 2 is an I-beam rod, which has high structural strength and low cost, and can directly use the I-beam rods at the construction site. Of course, in other embodiments of the present invention, the connecting rod 2 can be made of other materials according to actual conditions, and is not limited to the I-beam rod.

[0038] Optionally, the operating platform 1 is a hanging basket having a guardrail to protect the personal safety of the operator. The hanging basket has a large space for convenient placement of the metal aluminum edge to be installed.

[0039] Optionally, the construction device of the cantilever roof also includes an anti-fall safety lock, which is arranged between the connecting rod 2 and the operating platform 1, further providing personal safety for the operator and preventing falling.

[0040] Optionally, the connecting line 5 is a steel wire rope, which has high strength, corrosion resistance, and is not easy to break. Of course, in other embodiments of the present invention, the connecting line 5 can be made of other materials with excellent performance according to actual needs.

[0042] S1: The driving member 3 is fixed on one of the longitudinal beams 300, the two ends of the connecting rod 2 are stopped on two of the cross beams 200, the two ends of the connecting rod 2 are respectively connected to the operating platform 1 through a hoist, the guide assembly 4 is placed in the beam groove of the cross beam 200 and connected to the connecting rod 2, and a connecting line 5 is connected between the driving member 3 and the connecting rod 2;

[0043] S2: Start the driving member 3 to pull the connecting wire 5 to move along the length direction of the beam 200, thereby driving the operating platform 1 to move along the length direction of the beam 200, and the operator on the operating platform 1 installs the metal aluminum edge on the cantilever roof until it moves to the longitudinal beam 300;

[0044] S3: Remove the driving part 3 from the longitudinal beam 300 and reinstall it on another longitudinal beam 300. The hoist will lay out the operating platform 1 in the direction away from the cross beam 200 until the operating platform 1 is placed on the roof panel. The tower crane will lift the connecting rod 2 and the guide assembly 4 and place them on the other two cross beams 200, and move the operating platform 1 to the bottom of the cross beam 200. The operating platform 1 will be connected to the connecting rod 2 again, and the operator on the operating platform 1 will install the metal aluminum edge again.
