[0002] During construction, especially of high-rise buildings, protective devices need to be installed on the exterior walls of the building. Construction workers stand within these protective devices to work on or decorate the exterior walls. These devices are typically composed of steel pipes, walkways, and related connectors, with a protective netting around the outside. Construction workers can move freely within these devices. These protective devices not only facilitate the movement of construction workers at heights and make construction easier, but also prevent falls from heights, protecting the personal safety of construction workers.

[0003] Currently, protective devices constructed using this type of scaffolding are typically fixed directly to the building's exterior walls via steel pipes. While this connection method is simple and convenient, its stability is not high, especially at high-rise buildings, where there is a risk of the protective devices tilting outwards or falling off.

[0004] Therefore, addressing the shortcomings of the existing technologies has become the focus of efforts for those skilled in the field. Summary of the Invention

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] As shown in Figures 1, 2, 3, 4, and 5, a wall-connecting unloading device includes a wall-connecting unloading device body 101. The wall-connecting unloading device body 101 includes an outer connecting plate 1, an inner connecting plate 3, and left and right side plates 2. The outer connecting plate 1 and the inner connecting plate 3 are parallel to each other, and the length of the inner connecting plate 3 is greater than the length of the outer connecting plate 1. The outer connecting plate 1, the inner connecting plate 3, and the left and right side plates 2 form a trapezoidal structure. To achieve a better unloading effect, the lengths of the left and right side plates are the same, and the entire wall-connecting unloading device is an isosceles trapezoidal structure. The outer connecting plate 1 and the inner connecting plate 3 are hollow rectangular tube structures. The hollow rectangular tubes can reduce weight without weakening the unloading capacity, and the hollow tubes can connect multiple wall-connecting unloading devices at corresponding positions into one unit.

[0025] In this embodiment, in order to facilitate the separate connection between the building exterior wall and the protective device, some connection structures need to be designed. To reduce costs, this embodiment adopts a bolt-and-threaded-hole structure, as detailed below:

[0026] When connected to the protective device: the outer plate 1 has a threaded hole 12, and also includes a corresponding bolt 4 and nut 5. The bolt 4 corresponds to the threaded hole 12. The bolt 4 passes through the threaded hole 12 on the wall-connecting unloading device body 101 and the protective device 103 from the inside of the outer plate 1. The nut 5 is fixed to the bolt 4. The support column of the protective device has corresponding holes. The bolt 1 fixes the protective device and the outer plate, and then fixes them together with the bolt 1. For overall stability, two or more threaded holes can be provided, corresponding to multiple bolts, making the fixation more secure.

[0027] When connected to the building's exterior wall: The inner side of the inner plate 3 is provided with a long strip-shaped hole 32, and the outer side of the inner plate 3 is provided with a second adjustment hole 33 corresponding to the long strip-shaped hole. The second through-wall bolt 6 passes through the long strip-shaped hole 32, the second adjustment hole 33 and the building's exterior wall 102 in sequence, and the second nut 7 is fixed on the second through-wall bolt 6.

[0028] To strengthen the wall connection, it also includes a No. 3 through-wall bolt 8 and a No. 3 nut 9. Two No. 3 threaded holes 34 are also provided on the outer side of the inner plate 3, symmetrically arranged on both sides of the No. 2 adjustment hole 33. The No. 3 through-wall bolt 8 passes sequentially through the elongated slot 32, the No. 3 threaded hole 34, and the building's outer wall 102. The No. 3 nut 9 is fixed to the No. 3 through-wall bolt 8. Because the inner plate is a hollow rectangular tube structure, the area of ​​the elongated slot on the inner side is larger than the area of ​​the No. 2 adjustment hole 33, facilitating bolt installation. The No. 2 nut on the No. 2 through-wall bolt can be installed in two ways: one is to use a washer with an area larger than the elongated slot, fixing the No. 2 nut outside the washer; the other is to rotate the No. 2 nut through the elongated slot and finally fix it between the inner and outer sides of the inner plate, above the No. 2 adjustment hole. The No. 2 adjustment hole can also be an elongated structure or a circular hole, depending on the actual design. The installation method of the No. 3 through-wall bolt and No. 3 nut, which play a reinforcing role, is similar to that of the No. 2 through-wall bolt, and will not be described again here.

[0029] The side plate 2 is a hollow rectangular tube structure with threaded holes 21. The threaded holes 21 on the left and right side plates 2 are corresponding and located at the same horizontal position. The side plate serves to unload loads, therefore, it needs to be made of sheet material with a certain strength.

[0030] Example 2:

[0031] As shown in Figure 6, compared with Embodiment 1, a wall-connected unloading device includes a wall-connected unloading device body 101. The wall-connected unloading device body 101 includes an outer connecting plate 1, an inner connecting plate 3, and left and right side plates 2. The outer connecting plate 1 and the inner connecting plate 3 are parallel to each other, and the length of the inner connecting plate 3 is greater than the length of the outer connecting plate 1. The outer connecting plate 1, the inner connecting plate 3, and the left and right side plates 2 form a trapezoidal structure. To achieve a better unloading effect, a reinforcing connecting rib 10 is also included. One end of the reinforcing connecting rib 10 is fixed to the left side of the outer connecting plate 1, and the other end of the reinforcing connecting rib is fixed to the right side of the inner connecting plate. The outer connecting plate 1, the reinforcing connecting rib 10, and the inner connecting plate 3 form a "Z" shape. The "Z" shape can decompose the body into two triangles, making the force more balanced and stabilizing the entire wall-connected unloading device and the connected protective device, thus unloading the overall weight. The outer connecting plate 1 has a square cross-section of a hollow rectangular tube structure.

[0032] The end of the outer plate 1 is an outer plate through hole 11; multiple outer plates can be connected into one unit by a steel pipe.

[0033] The hollow rectangular tube structure of the inner plate 3 has a square cross-section, and the end of the inner plate 3 is an inner plate through hole 31. Multiple inner plates can be connected into one piece by a steel pipe.

[0034] The side plate 2 is a solid tube with threaded holes. The solid tube can provide strong support, and the threaded holes can fix other steel pipes.

[0035] The wall-connecting unloading device of this utility model is designed in a trapezoidal shape. The inner and outer connecting plates can effectively connect the protective device and the building's outer wall together. The side plates and the entire trapezoidal shape can play a role in unloading, preventing the entire protective device from tilting outward or falling off.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
