[0013] Furthermore, the adjustable edge protection device for the blank section between the cantilevered unloading steel platform and the building structure provided by the present invention includes an adjustable fixed upright and a sliding groove at its lower end. The sliding groove is fitted on the blank section of each main beam of the cantilevered unloading steel platform, and the sliding groove is provided with a moving wheel for moving on the upper surface of each main beam of the cantilevered unloading steel platform.

[0034] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

The main beams 110 can be H-beams or I-beams.

[0036] Please refer to Figures 1 to 4 This invention provides an adjustable edge protection device 300 for the gap between a cantilevered unloading steel platform and a building structure, comprising a slot 310, an adjustable fixed upright 320, an adjustable movable upright 330, and a lateral telescopic rod 340, wherein:

[0037] There are two slots 310, which are vertically welded to the blank sections of the main beams 110 of the cantilevered unloading steel platform 100 near the main guardrail 140 of the cantilevered unloading steel platform 100. The two slots 310 on the two main beams 110 are aligned and distributed.

[0038] Two adjustable fixed poles 320 are vertically inserted and connected to each of the slots 310.

[0039] Two adjustable movable uprights 330 are slidably connected to the blank sections of the main beams 110 of the cantilevered unloading steel platform 100, parallel to the adjustable fixed uprights 320.

[0040] The transverse telescopic rods 340 are in two sets, and are horizontally welded between the adjustable fixed uprights 320 and the adjustable movable uprights 330 on each main beam 110 of the cantilevered unloading steel platform 100.

[0041] Please refer to Figures 1 to 4 The present invention also provides a method for using the adjustable edge protection device 300 for the gap between a cantilevered unloading steel platform and a building structure, as described above, including:

[0042] Step S401: Insert two adjustable fixed uprights 320 into two slots 310 that are aligned and welded on the two main beams 110 connected to the cantilevered unloading steel platform 100.

[0043] Step S402: Slidably connect two adjustable movable uprights 330 to the two main beams 110 of the cantilevered unloading steel platform 100.

[0044] In step S403, adjust each adjustable fixed upright 320 and each adjustable movable upright 330 to the same height. Preferably, the adjusted height is consistent with the height of the main body guardrail 140 of the cantilevered unloading steel platform 100.

[0045] Step S404: Adjust the length of each set of horizontal telescopic rods 340, and move the two adjustable movable uprights 330 along the blank section of the cantilevered unloading steel platform 100 into the building structure 200 to form temporary protection in the blank section between the cantilevered unloading steel platform 100 and the building structure 200.

[0046] Please refer to this carefully. Figure 1The adjustable edge protection device 300 and its usage method for the gap between a cantilevered unloading steel platform and a building structure provided in this embodiment of the invention, consists of two adjustable fixed uprights 320 inserted into slots 310 welded to the main beam 110 of the cantilevered unloading steel platform 100, two adjustable movable uprights 330 slidably connected to the main beam 110 of the cantilevered unloading steel platform 100, and transverse telescopic rods 340 horizontally connected between the adjustable fixed uprights 320 and the adjustable movable uprights 330 of each main beam 110. After the cantilevered unloading steel platform 100 is anchored to the building structure 200, the adjustable edge protection device 300 is used by adjusting the horizontal telescopic rods 340. The adjustable movable uprights 330 are moved along the blank section of the cantilevered unloading steel platform 100 into the building structure 200 to form a temporary protective structure in the blank section between the cantilevered unloading steel platform 100 and the building structure 200. This avoids the safety hazard caused by the lack of protection in the blank section where the cantilevered unloading steel platform 100 is installed on the building structure 200, and has the advantages of low cost and convenient installation. The adjustable edge protection device 300 can be used for the rapid construction of temporary protective structures for blank sections of various lengths, and has the advantage of wide applicability. By forming temporary protection in the blank section with the adjustable edge protection device 300, the safety hazard caused by the lack of protection in the blank section is filled, ensuring construction safety.

[0047] Please refer to this carefully. Figure 4 The adjustable edge protection device 300 and its usage method for the blank section between the cantilevered unloading steel platform and the building structure provided in this embodiment of the invention, when used in conjunction with external scaffolding, allows the adjustable movable column to be located on the building structure 200 by installing the transverse telescopic rod 340 through the external scaffolding, without affecting the use of the external scaffolding.

[0048] Please refer to Figures 3 to 4 In order not to occupy the surface space of the main beam 110, the adjustable edge protection device 300 and its usage method for the blank section between the cantilevered unloading steel platform and the building structure provided in this embodiment of the invention, wherein the slot 310 is located on the outside or inside of the main beam 110. Figure 4 The example illustrates the case where the slot 310 is welded to the inside of the main beam 110.

[0049] Please refer to Figure 1 and Figure 3To achieve rapid assembly and connection between the adjustable fixed pole 320 and the slot 310, this embodiment of the invention provides an adjustable edge protection device 300 and its usage method for the blank section between a cantilevered unloading steel platform and a building structure. The slot 310 is tubular, and the corresponding adjustable fixed pole 320 is also tubular. For example, the slot 310 can be a square tube, and the corresponding adjustable fixed pole 320 can be a round tube. Alternatively, the slot 310 can be a round tube, and the corresponding adjustable fixed pole 320 can be a round tube. For ease of adjustment, the adjustable fixed pole 320 can be a snap-fit ​​adjustment rod with several through holes spaced apart on one section and a spring clip on the other section. Of course, the adjustable fixed pole 320 is not limited to this telescopic adjustment structure. To prevent the adjustable fixed pole 320 from falling out after being inserted into the slot 310, the slot 310 is a bottomed slot, i.e., a groove rather than a through slot.

[0050] Please refer to Figure 1 and Figure 2 To ensure the adjustable movable upright 330 slides stably on the main beam 110 without detaching, this invention provides an adjustable edge protection device 300 and its method of use for the blank section between the cantilevered unloading steel platform and the building structure. The adjustable movable upright 330 includes an adjustable fixed upright 320 and a sliding groove 331 at its lower end. The sliding groove 331 is fitted onto the blank section of each main beam 110 of the cantilevered unloading steel platform 100. The sliding groove 331 contains movable wheels 332 for moving on the upper surface of each main beam 110 of the cantilevered unloading steel platform 100. By fitting the sliding groove 331 onto the main beam 110, the adjustable movable upright 330 is restricted from sliding on the main beam 110, thus preventing the adjustable movable upright 330 from detaching from the main beam 110.

[0051] Please refer to Figure 1 To ensure effective protection, the adjustable edge protection device 300 and its usage method for the gap between the cantilevered unloading steel platform and the building structure provided in this embodiment of the invention include at least two transverse telescopic rods 340 in each group. The figure illustrates two transverse telescopic rods 340. To achieve telescopic adjustment, the transverse telescopic rods 340 can be snap-on type.
