Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, and particularly relates to a scaffolding with a falling prevention structure. Background Art

[0002] A scaffolding is various supports erected at the construction site for workers to operate and solve vertical and horizontal transportation problems. During the construction of building houses, such as interior wall plastering, painting, exterior wall painting and trimming of houses, scaffolding is mainly used for construction workers to work up and down, enclose the periphery with safety nets, and install components. Traditional scaffolding is generally composed of relatively light alloy steel pipes welded and fixed. Usually, on one side of the common scaffolding, multiple short steel pipes are arranged at equal intervals in the height direction and welded and fixed on the main support steel pipe of the scaffolding. When construction workers climb up the scaffolding, they need to climb up on the above-mentioned short steel pipes with both hands and feet.

[0003] In order to improve the side protection effect of the scaffolding, a special falling prevention structure is often set on the side of the scaffolding. However, the existing side falling prevention structure is often a fixed-position protection frame, similar to a grille. Although it can reduce the risk of workers falling, due to the existence of the grille, the working area is greatly limited, and workers often need to put their hands through the protection frame to carry out subsequent related construction, which limits the flexibility of construction.

[0004] Therefore, it is necessary to invent a scaffolding with a falling prevention structure to solve the above problems. Content of the Utility Model

[0005] In order to solve the deficiencies of the prior art, the purpose of the utility model is to provide a scaffolding with a falling prevention structure, which solves the problem that the existing side falling prevention structure in the prior art is often a fixed-position protection frame, similar to a grille. Although it can reduce the risk of workers falling, due to the existence of the grille, the working area is greatly limited, and workers often need to put their hands through the protection frame to carry out subsequent related construction, which limits the flexibility of construction.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A scaffolding with an anti-falling structure, comprising a bottom plate, a middle frame plate provided at the middle of one end of the top surface of the bottom plate, and two side frame plates provided at both sides of one end of the top surface of the bottom plate. A rotating rod is rotatably provided between the middle of one side of the middle frame plate and the middle of the side frame plate. A plurality of linkage frames are rotatably sleeved on the rotating rod. A bottom protection frame is rotatably clamped between one ends of the plurality of linkage frames, and a top protection frame is rotatably clamped between the other ends of the plurality of linkage frames. And the bottom end of the bottom protection frame can be clamped between the bottom ends of the middle frame plate and the side frame plates, and the top end of the top protection frame can be clamped between the top ends of the middle frame plate and the side frame plates.

[0008] As a preferred solution of the present invention, arc-shaped grooves are provided on both sides of the middle of the middle frame plate and in the middle of the side frame plates, and both ends of the rotating rod can rotate along the arc of the arc-shaped grooves.

[0009] As a preferred solution of the present invention, bottom clamping grooves are provided on both sides of the bottom end of the middle frame plate and at the bottom ends of the side frame plates;

[0010] When the bottom protection frame rotates to a vertical state, both ends of the bottom end of the bottom protection frame are respectively clamped into the corresponding bottom clamping grooves.

[0011] As a preferred solution of the present invention, top clamping grooves are provided on both sides of the top end of the middle frame plate and at the top ends of the side frame plates;

[0012] When the top protection frame rotates to a vertical state, both ends of the top end of the top protection frame can be clamped into the corresponding top clamping grooves.

[0013] As a preferred solution of the present invention, connecting columns are installed at the positions of each top clamping groove on the middle frame plate and the side frame plates, and a sealing plate that can close or open the top clamping groove is rotatably sleeved on the connecting column.

[0014] As a preferred solution of the present invention, an inner support plate is detachably installed in the bottom plate, and a ground support frame is detachably installed at the bottom end of the bottom plate.

[0015] As a preferred solution of the present invention, the longitudinal lengths of the bottom protection frame and the top protection frame are the same.

[0016] In the above technical solution, the technical effects and advantages provided by the present invention:

[0017] In the present utility model, the bottom protection frame and the top protection frame can serve as anti-falling structures on one side of the middle frame plate and the side frame plate. By means of the linkage frame, the bottom protection frame and the top protection frame can be rotated to a non-overlapping vertical state, completely enclosing the working area on one side of the middle frame plate and the side frame plate. At this time, the staff needs to pass their hands through the bottom protection frame and the top protection frame to carry out subsequent construction operations; when the top protection frame is rotated by the linkage frame to coincide with the vertical state of the bottom protection frame, that is, the bottom protection frame and the top protection frame are vertically overlapped below the middle of the middle frame plate, so as to carry out anti-falling protection in this part and open the construction space above the middle of the middle frame plate; when the bottom protection frame is rotated by the linkage frame to coincide with the vertical state of the top protection frame, that is, the bottom protection frame and the top protection frame are vertically overlapped above the middle of the middle frame plate, so as to carry out anti-falling protection in this part and open the construction space below the middle of the middle frame plate. Thus, on the premise of ensuring the anti-falling effect, the construction space between the bottom protection frame and the top protection frame can be flexibly opened, improving the flexibility of construction.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below in conjunction with the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0024] The present utility model provides as Figures 1-3A scaffolding with an anti-falling structure as shown includes a bottom plate 1, a middle frame plate 4 provided in the middle of one end of the top surface of the bottom plate 1, and two side frame plates 5 provided at both sides of one end of the top surface of the bottom plate 1. A rotating rod 7 is rotatably provided between the middle of one side of the middle frame plate 4 and the middle of the side frame plate 5. A plurality of linkage frames 8 are rotatably sleeved on the rotating rod 7. A bottom protection frame 9 is rotatably clamped between one ends of the plurality of linkage frames 8, and a top protection frame 10 is rotatably clamped between the other ends of the plurality of linkage frames 8. The bottom end of the bottom protection frame 9 can be clamped into the space between the bottom ends of the middle frame plate 4 and the side frame plate 5, and the top end of the top protection frame 10 can be clamped into the space between the top ends of the middle frame plate 4 and the side frame plate 5.

[0025] Arc-shaped grooves 6 are provided on both sides of the middle of the middle frame plate 4 and in the middle of the side frame plate 5. Both ends of the rotating rod 7 can rotate along the arc of the arc-shaped groove 6. The existence of the arc-shaped groove 6 can, on the one hand, facilitate the rotation of both ends of the rotating rod 7 therein and can also facilitate the change of position during the rotation.

[0026] Bottom card slots 11 are provided on both sides of the bottom end of the middle frame plate 4 and at the bottom ends of the side frame plates 5;

[0027] When the bottom protection frame 9 rotates to the vertical state, both ends of the bottom end of the bottom protection frame 9 are respectively clamped into the corresponding bottom card slots 11. When the bottom end of the bottom protection frame 9 is completely within the bottom card slots 11, the bottom protection frame 9 rotates to the vertical state, thereby providing anti-falling protection below the middle of the middle frame plate 4.

[0028] Top card slots 12 are provided on both sides of the top end of the middle frame plate 4 and at the top ends of the side frame plates 5;

[0029] When the top protection frame 10 rotates to the vertical state, both ends of the top end of the top protection frame 10 can be clamped into the corresponding top card slots 12. Connecting columns 13 are installed at the positions of each top card slot 12 corresponding to the middle frame plate 4 and the side frame plate 5. A sealing plate 14 that can close or open the top card slot 12 is rotatably sleeved on the connecting column 13. When both ends of the top end of the top protection frame 10 can be clamped into the corresponding top card slots 12, the top card slot 12 can be closed by the sealing plate 14, thereby locking the vertical position of the top protection frame 10.

[0030] An inner support plate 2 is detachably installed inside the bottom plate 1, and a ground support frame 3 is detachably installed at the bottom end of the bottom plate 1. The inner support plate 2 serves as the standing construction area for workers, and the ground support frame 3 can lift the construction area by a certain vertical distance.

[0031] The longitudinal lengths of the bottom protection frame 9 and the top protection frame 10 are the same, which facilitates their being clamped into the bottom card slots 11 and the top card slots 12 when they are vertically overlapped.

[0032] In the present utility model, the bottom protection frame 9 and the top protection frame 10 can serve as anti-falling structures on one side of the middle frame plate 4 and the side frame plate 5. By rotating the bottom protection frame 9 and the top protection frame 10 to a non-coincident vertical state through the linkage frame 8, the working area on one side of the middle frame plate 4 and the side frame plate 5 can be completely enclosed. At this time, the staff needs to pass their hands through the bottom protection frame 9 and the top protection frame 10 to perform subsequent construction operations; when the top protection frame 10 is rotated to coincide with the vertical state of the bottom protection frame 9 through the linkage frame 8, that is, the bottom protection frame 9 and the top protection frame 10 are vertically coincident below the middle of the middle frame plate 4, so as to carry out anti-falling protection in this part and open the construction space above the middle of the middle frame plate 4; when the bottom protection frame 9 is rotated to coincide with the vertical state of the top protection frame 10 through the linkage frame 8, that is, the bottom protection frame 9 and the top protection frame 10 are vertically coincident above the middle of the middle frame plate 4, so as to carry out anti-falling protection in this part and open the construction space below the middle of the middle frame plate 4. Thus, on the premise of ensuring the anti-falling effect, the construction space between the bottom protection frame 9 and the top protection frame 10 can be flexibly opened, improving the flexibility of construction.

[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
