Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding flaps, in particular to a retractable flap of an attached lifting scaffolding. Background Art

[0002] During the construction process, because space must be reserved for exterior wall operations, there is a gap of several dozen centimeters between the scaffolding set up outside the building and the building wall. These gaps can easily cause workers to step on empty space and objects to fall, so flaps are used to fill the gaps to avoid falling accidents.

[0003] The existing flap is directly connected to the scaffolding board, and its length is fixed, and it cannot be adjusted according to different stair gaps, so it is necessary to design a flap specifically. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned problem, the purpose of the utility model is to provide a retractable flap of an attached lifting scaffolding, including a main flap, which is connected to the scaffolding board through a hinge, and a retractable plate is clamped in the main flap, which can extend out of the main flap in a direction perpendicular to the rotation axis of the main flap, and the maximum rotation angle of the main flap is 180°.

[0005] Preferably, a handle is provided on the telescopic plate for controlling the retraction / extension of the telescopic plate onto the main flap.

[0006] Preferably, the handle is located on a side of the telescopic plate close to the main flap.

[0007] Preferably, it also includes a connecting rod telescopic assembly, and both ends of the connecting rod telescopic assembly are respectively connected to the main flap and the telescopic plate.

[0008] Preferably, the connecting rod telescopic assembly comprises a movable rod end, the movable rod end is rotatably connected with a sleeve, the sleeve is sleeved on the travel rod and can translate along the axial direction of the travel rod.

[0009] Preferably, a sliding block is sleeved on the travel rod, a locking bolt is threadedly connected to the sliding block, and one end of the locking bolt can abut against the travel rod.

[0010] The beneficial effects of the utility model are:

[0011] A telescopic plate is arranged inside the main flap. The telescopic plate can be retracted / extended from the main flap and can be adjusted according to different stair gaps to fill the gaps in the building that cannot be covered by the existing flap, thereby preventing construction workers from stepping on empty space and falling, and construction objects from falling, thereby ensuring the safety of construction.

[0023] Embodiment 1:

[0024] Figure 1-Figure 5 The utility model shows an attached lifting scaffolding retractable flap provided by the utility model, comprising a main flap 1 and a retractable plate 2 embedded in the main flap 1, the main flap 1 is rotatably connected to the scaffolding board 5 in the scaffolding through a hinge 11, the retractable plate 2 is clamped with the main flap 1, and can extend the main flap 1 in a direction perpendicular to the rotation axis of the main flap 1, the maximum rotation angle of the main flap 1 is 180°, and the main flap 1 is overlapped on the scaffolding board 5 before use, which is the first state of the main flap 1, and the construction personnel can first visually measure the distance from the building wall and pull out the retractable plate 2 of the corresponding length; after the retractable plate 2 is pulled out, the construction personnel flip the main flap 1 together with the retractable plate 2 180°, at this time, the end of the retractable plate 2 away from the main flap 1 is close to the building outer wall 6 or abuts against the building outer wall 6, which is the second state of the main flap 1, and in the second state, the main flap 1 and the retractable plate 2 fill the gap between the scaffolding and the building wall, which can prevent people or objects from falling from high altitude.

[0025] A handle 21 is installed on the telescopic plate 2, which is used to pull / push the telescopic plate 2 to retract / extend the main flap 1. The handle 21 is set on the side of the telescopic plate 2 close to the main flap 1. That is to say, in the second state of the main flap 1, the handle 21 is located at the upper end surface of the telescopic plate 2. The construction workers can stand on the scaffolding board 5, reach out or use other tools to pull / push the handle 21, and slightly adjust the telescopic plate 2.

[0026] A connecting rod telescopic assembly 3 is also provided, and the two ends of the connecting rod telescopic assembly 3 are respectively connected to the main flap 1 and the telescopic plate 2. The connecting rod telescopic assembly 3 includes two fixed seats respectively arranged on the main flap 1 and the telescopic plate 2. The two fixed seats are connected to each other through a connecting rod group, which can prevent the telescopic plate 2 from being separated from the main flap 1. The connecting rod group includes a movable rod end 31

[0027] The movable rod end 31 is hinged with a sleeve 41, which is sleeved on a travel rod 4 and can slide and translate along the axial direction of the travel rod 4. In this embodiment, two connecting rod groups are provided to maintain balance, so there are a total of two movable rod ends 31 respectively connected to the two travel rods 4.

[0028] A sliding block 42 is also sleeved on the travel rod 4, and a locking bolt 43 is threadedly connected to the sliding block 42. One end of the locking bolt 43 can abut against the travel rod 4. Tightening the locking bolt 43 can fix the sliding block 42 at an arbitrary position on the travel rod 4. After fixation, the maximum stroke of the sleeve 41 can be limited, thereby limiting the expansion action of the connecting rod group, and finally achieving the effect of limiting the maximum length of the extended part of the telescopic plate 2.

[0029] Working principle:

[0030] A slot for snapping is provided in the main flap 1, and a telescopic plate 2 that can be snapped into the main flap 1 is provided. The main flap 1 is pre-connected with the scaffolding board 5 through a hinge 11. When in use, the construction worker visually measures the length of the gap between the edge of the scaffolding board 5 and the building wall, pulls out the telescopic plate 2 of the corresponding length, and then flips the main flap 1 and the telescopic plate 2. Since the construction worker's visual measurement is not accurate, the final extended length of the telescopic plate 2 may be longer or shorter; the first case is when the telescopic plate 2 extends longer, at this time the telescopic plate 2 usually directly rests on the building wall, and the main flap 1 is relatively close to the telescopic plate 2. The horizontal plane has a certain inclination angle. Since the main flap 1 and the telescopic plate 2 play a protective role to prevent falling, in principle, construction workers are not allowed to stand or walk on it, so a slight inclination angle is acceptable; the second case is when the telescopic plate 2 is extended to a shorter length. At this time, there is still a small gap between the telescopic plate 2 and the building wall. Similarly, since the main flap 1 and the telescopic plate 2 play a protective role to prevent falling, a smaller gap does not affect the protective role, and it can still prevent people or objects from falling. Therefore, even if there is still a small gap between the telescopic plate 2 and the building wall, it does not affect its effect.

[0031] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
