[0025] 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 of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0026] like Figures 1 to 8 As shown, this embodiment discloses a standardized scaffolding for rigid landfill cells, including a unit frame, the unit frame including a pedal board 2 and four columns 1 arranged at the end corners of the pedal board 2, and a splint member 4 is arranged on the outer side of the middle part of the four columns 1 and is bolted to the pedal board 2 through the splint member 4.

[0027] The unit frames are multiple and multiple unit frames are stacked vertically;

[0028] like Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the column 1 is in the shape of a hollow tube and is arranged vertically. A plurality of elastic rods 101 are arranged at equal intervals on the inner wall of the top end of the column 1 along the circumferential direction of the column 1. The bottom ends of the elastic rods 101 are welded to the inner wall of the top end of the column 1. A snap-in protrusion 102 is arranged on the outer side of the top end of the elastic rod 101. The outer end of the snap-in protrusion 102 is arranged to be tilted downward. An annular snap-in groove 103 is arranged on the inner wall of the bottom end of the column 1 along the circumferential direction of the column 1. The bottom end wall of the annular snap-in groove 103 is arranged to be tilted upward on one side close to the inner wall of the column 1. When a plurality of unit frames are stacked longitudinally, the snap-in protrusion 102 on the top end of the elastic rod 101 in the unit frame is engaged with the annular snap-in groove 103 on the inner wall of the bottom end of the column 1 in the upper adjacent unit frame.

[0029] When multiple unit frames are stacked and placed, the bottom end of the column in the upper unit frame is coaxially placed with the column of the lower unit frame. When the bottom end of the column in the upper unit frame is close to the top end of the column of the lower unit frame, the bottom end of the column in the upper unit frame will squeeze the top end of the elastic rod and make it tilt toward the center position of the column. As the upper unit frame continues to move, when the clamping protrusion at the top end of the elastic rod reaches the position of the annular clamping groove, it is clamped into the annular clamping groove under the elastic action of the elastic rod, thereby realizing a stable connection between the columns in the upper unit frame and the lower unit frame; at the same time, by setting the inclined surfaces of the clamping protrusion and the inner wall of the bottom end of the annular clamping groove, it is not easy to loosen after being clamped. After construction, when the scaffold is hoisted out of the rigid landfill unit cell, it is only necessary to lift the uppermost unit frame to lift all the unit frames together under the action of the clamping connection structure. The whole operation is simple and fast, which effectively improves the loading and unloading efficiency of the scaffold in the rigid landfill unit cell.

[0030] A plurality of unloading ports 104 are arranged on the inner wall of the annular slot 103 along the circumferential direction of the column 1 and are communicated with the outer side of the column 1 . The plurality of unloading ports 104 are arranged corresponding to the clamping protrusions 102 of the plurality of elastic rods 101 to facilitate the separation operation of the plurality of longitudinally stacked unit frames.

[0031] After all the unit frames are hoisted out, the clamping protrusions and the annular clamping grooves can be separated through the loading and unloading openings by using special tools, thereby realizing the separation operation of multiple superimposed unit frames and facilitating the reuse of the unit frames.

[0032] A guide sleeve 5 is provided at the top of the column 1; the bottom end of the guide sleeve 5 is arranged in a vertical tubular shape, the inner diameter of the bottom end of the guide sleeve 5 is consistent with the outer diameter of the column 1, the bottom end of the guide sleeve 5 is sleeved on the outside of the top end of the column 1 and the inner wall of the bottom end of the guide sleeve 5 is threadedly connected to the outer wall of the top end of the column 1; the top end of the guide sleeve 5 is arranged in a trumpet shape; when several unit frames are stacked longitudinally, the bottom end of the column 1 in the upper adjacent unit frame extends into the top end of the guide sleeve 5 and slides to the bottom end of the inner side of the guide sleeve 5, so that the column 1 in the unit frame is coaxially arranged with the column 1 in the upper adjacent unit frame, and the clamping protrusion 102 at the top of the elastic rod 101 is engaged with the annular clamping groove 103 on the inner wall of the bottom end of the column 1 in the upper adjacent unit frame.

[0033] The guide sleeve can assist the columns in the upper unit frame to quickly and accurately achieve coaxial placement operation with the columns in the lower unit frame. During placement, under the action of the trumpet at the top end of the guide sleeve, the columns in the upper unit frame can slide to the bottom end of the guide sleeve to achieve a stable connection between the columns of the upper unit frame and the columns of the lower unit frame; and after the connection, the bottom end of the columns of the upper unit frame and the top end of the columns of the lower unit frame are both located on the inner side of the bottom end of the guide sleeve, which can avoid tilting or dislocation of the upper unit frame during use, improve the stability of adjacent unit frames after connection, and ensure the construction safety performance of the scaffolding.

[0034] When disassembling multiple unit frames, the guide sleeve is separated from the lower unit frame column and slid onto the upper unit frame column, and then the upper unit frame column is separated from the lower unit frame column using a tool.

[0035] like Figure 6 , Figure 8 As shown, a hanging part is arranged on the inner side of the top of the column 1; the hanging part includes a slider 7 and a lifting ring 6, a limiting plate 8 is fixedly connected to the inner side of the middle part of the column 1, the slider 7 is arranged between the limiting plate 8 and the bottom end of the elastic rod 101 and the slider 7 can slide in the column 1 along the axial direction of the column 1, the top of the slider 7 is fixedly connected to the lifting ring 6 and the lifting ring 6 is located between several elastic rods 101; when several unit frames are in a longitudinally stacked state, the slider 7 contacts the top of the limiting plate 8 under the action of gravity, and the top height of the lifting ring 6 is not higher than the top height of the elastic rod 101; when the unit frame is in a hanging state, the slider 7 moves upward to make the top of the slider 7 contact the bottom end of the elastic rod 101, and the top of the lifting ring 6 extends to the outside of the top of the guide sleeve 5.

[0036] The lifting parts are arranged at the top of the four columns of the unit frame. When performing lifting operations, the lifting ropes can be directly connected to the four lifting parts to perform lifting operations. In order to avoid the lifting parts from obstructing the longitudinally stacked unit frames, the lifting parts are usually located on the inner side of the columns when not performing lifting. When performing lifting, the top of the lifting ring is pulled out from the top of the column, so that the top of the lifting ring is connected to the lifting rope for lifting operations.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the pedal board 2 is provided with an upper and lower avoidance opening 201, and a staircase 3 is provided at the bottom end of the pedal board 2. The top end of the staircase 3 is hinged to a connecting ear 202 provided at one side of the bottom end of the upper and lower avoidance opening 201, and the bottom end of the staircase 3 abuts against the pedal board 2 of the adjacent unit frame on the ground or below under the action of gravity.

[0038] The bottom end of the stepping board 2 is provided with a hanging piece 203, and the hanging piece 203 is arranged corresponding to the side wall of the staircase 3; when the unit frame is in the hoisting state, the staircase 3 is rotated to be parallel to the stepping board 2, and then the hanging piece 203 is engaged and connected with the side wall of the staircase 3.

[0039] When the stairs are being hoisted, in order to prevent the bottom of the stairs from swinging randomly, the stairs are rotated to be parallel to the stepping board and then hung on the bottom of the stepping board through a hanging piece. When in use, it is removed from the hanging piece, and the bottom of the stairs abuts against the ground or the stepping board of the next unit frame under the action of gravity. Construction workers can move up and down on the stepping boards of multiple unit frames through the stairs and the upper and lower avoidance openings, which provides convenience for construction operations.

[0040] When the utility model is in use, a plurality of unit frames can be directly assembled on the outside of the cells of the rigid landfill, and then a unit frame can be directly hoisted into the cells of the rigid landfill for construction and use using a hoisting device. As the construction height increases, another unit frame is hoisted and placed above the original unit frame to achieve a stable connection, and this reciprocating operation can be performed by superimposing a plurality of unit frames to achieve the construction effect in the cells of the rigid landfill. It does not require on-site erection operations in the cells of the rigid landfill, which improves the convenience of scaffolding installation and saves time and effort for the entire scaffolding installation operation. Moreover, after the construction in the cells of the rigid landfill is completed, it only needs to hoist the uppermost unit frame to hoist all the unit frames in the cells of the rigid landfill together, which effectively improves the construction efficiency of the rigid landfill and further improves the use effect of the utility model.
