Description

Technical Field

[0001] The utility model relates to the technical field of external wall panel hoisting, and more specifically, to a special hoisting device for vertically installing a large ALC external wall panel. Background Art

[0002] ALC exterior wall panels are autoclaved lightweight concrete panels. With the development of my country's construction industry, more and more projects will use ALC wall panels. However, how to safely hoist the ALC exterior wall panels into place is particularly important. The hoisting of large ALC exterior wall panels with specifications of 6000*600*200mm is a key process in the installation process, especially when ALC is used as an exterior wall panel and installed vertically, safe hoisting measures are even more important.

[0003] Normally, the ALC exterior wall panel is directly lifted after being wrapped with a lifting belt for one week. This method has the risk of falling off, and it is difficult to unhook the panel after it is fixed, which poses a great safety hazard. In view of this, the utility model proposes a special lifting device for vertical installation of large ALC exterior wall panels. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a special hanger for vertical installation of large ALC exterior wall panels to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special hanger for vertical installation of large ALC exterior wall panels, comprising a hanger, one end of the hanger is formed into a hanger ring by bending and welding, the other end of the hanger is provided with an extension rod, the outside of the extension rod is provided with an anti-dropping nut with an inner diameter of 20 mm, the top and bottom of the anti-dropping nut are provided with anti-dropping handles, and the ALC exterior wall panel body is installed on the outside of the extension rod on one side of the anti-dropping nut.

[0006] It can be seen that in the above structure, one end of the extension rod can pass through the ALC exterior wall panel body, and the anti-dropping nut can be used to lock the ALC exterior wall panel body by rotating the anti-dropping handle to prevent it from falling off during hoisting. One end of the lifting ring is installed on the hook of the crane to realize the hoisting operation of the ALC exterior wall panel body.

[0007] In order to adjust the use length of the extension rod according to the thickness of the exterior wall panel and ensure that there is still a length of 50mm when the extension rod passes through the exterior wall panel, preferably, an adjustment cavity is opened at the end of the suspension rod and on one side of the extension rod, and an adjustment column is welded at one end of the extension rod. The adjustment column is located inside the adjustment cavity opened by the extension rod, and the inner wall of the adjustment cavity is provided with an internal thread groove, and the outer surface of the adjustment column is provided with an external thread groove, and the adjustment column is connected with the internal thread of the adjustment cavity.

[0008] Technical effects and advantages of the utility model:

[0009] 1. After drilling a hole at the upper center of the ALC exterior wall panel, one end of the extension rod is passed through the ALC exterior wall panel, and the anti-drop nut is tightened on the outer nut of the extension rod to lock the ALC exterior wall panel. The lifting ring formed by bending at one end of the suspension rod can be installed on the hook of the crane to realize the lifting and installation operation of the exterior wall panel. The overall lifting makes the exterior wall panel not easy to fall off and is convenient to unhook. At the same time, it is simple to prepare and easy to carry;

[0010] 2. By rotating the extension rod, the adjusting column at one end of the extension rod can rotate in the internal thread of the adjusting cavity opened in the suspension rod, so that the overall use length of the extension rod can be adjusted. Therefore, when hoisting exterior wall panels of different thicknesses, it can be ensured that there is still a certain length of the extension rod after passing through for locking the anti-dropping nut, thereby improving the use range of the suspension device.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] As attached Figure 1-4A special hanger for vertical installation of a large ALC exterior wall panel is shown, comprising a hanger 1, one end of the hanger 1 is formed into a hanger ring 2 by bending and welding, an extension rod 3 is arranged at the other end of the hanger 1, an anti-dropout nut 4 with an inner diameter of 20 mm is arranged on the outside of the extension rod 3, and anti-dropout handles 5 are arranged on the top and bottom of the anti-dropout nut 4, an ALC exterior wall panel body 6 is installed on the outside of the extension rod 3 on one side of the anti-dropout nut 4, the hanger 1 is made of φ20 mm steel bars, and the hanger 1 as a whole is bent into an L shape, a plurality of groups of thread threads are arranged on the outer surface of the extension rod 3, the anti-dropout nut 4 is connected to the outer thread of the extension rod 3 through a screw rod, the anti-dropout handle 5 is welded to the top and bottom of the anti-dropout nut 4, and the anti-dropout handle 5 is made of a φ20 mm steel bar head with a length of 50 mm.

[0018] Specifically, in this structure, the preparation steps for the sling are:

[0019] 1. Bend the φ20mm steel bar into an L shape as the hanger 1. After one end of the hanger 1 is bent 180 degrees to form a ring 2, it is fully welded on both sides with the straight section. The weld length shall not be less than 200mm and the weld must be full;

[0020] 2. The length of the straight section of the extension rod 3 at the hanging board end is determined by the thickness of the ALC exterior wall panel body 6 and can be adjusted to ensure that the exposed length of the thread is not less than 50mm after tightening the anti-falling device during the hoisting operation;

[0021] 3. The anti-dropping device consists of an anti-dropping nut 4 with an inner diameter of 20 mm and an anti-dropping handle 5. Two sections of φ20 mm steel bar heads with a length of not less than 50 mm are welded to the two ends of the anti-dropping nut 4 as the anti-dropping handle 5. Its main function is to facilitate workers to tighten the nut and prevent the ALC exterior wall panel body 6 from falling off during the lifting process.

[0022] In a specific embodiment, as shown in the attached Figure 3 As shown, an adjustment cavity 7 is opened at the end of the suspension rod 1 and on one side of the extension rod 3, an adjustment column 8 is welded to one end of the extension rod 3, the adjustment column 8 is inside the adjustment cavity 7 opened by the extension rod 3, the inner wall of the adjustment cavity 7 is provided with an internal thread groove, the outer surface of the adjustment column 8 is provided with an external thread groove, and the adjustment column 8 is connected by the internal thread of the adjustment cavity 7.

[0023] Specifically, in this structure, the length of the extension rod 3 can be adjusted according to the thickness of the ALC exterior wall panel body 6 to ensure that when one end of the extension rod 3 passes through the ALC exterior wall panel body 6, the length of the external thread is not less than 50 mm, specifically;
