Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering auxiliary tools, and more specifically, to a folding scaffold. Background Art

[0002] During the construction process of civil engineering projects, engineering personnel often need to work at heights. To facilitate going up and down and ensure the safety of construction workers, some auxiliary tools (such as ladders or scaffolds, etc.) are required for climbing. Scaffolds can not only solve the problem of vertical movement but also allow construction workers to move horizontally. Therefore, they are widely used in modern civil engineering construction. Existing scaffolds are generally built using steel pipes, and bolts are used to connect and fix between the steel pipes. After the construction is completed, they need to be dismantled one by one and rebuilt when used again. Although this design meets the construction needs to a certain extent, such a construction method requires a large amount of time and manpower before and after construction, has the disadvantages of affecting the construction progress of the project and prolonging the construction time, and the erected scaffold cannot be moved, with poor flexibility. The whole scaffold cannot be conveniently transported and is difficult to be directly applied to other project sites (and needs to be disassembled and reassembled again). Moreover, due to the non-foldable nature of this kind of scaffold, its huge volume makes it very difficult to store. Therefore, it must be disassembled and removed after use.

[0003] With the development of the economy, the requirement for construction speed is further increased. The existing scaffolds can no longer meet the project needs. Therefore, having a convenient-to-use scaffold is an urgent need for construction units, and this case is thus born. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a folding scaffold. The main body of the utility model includes a base, four side plates, and a top plate. When in use, the four side plates and the top plate can be quickly spliced to form a complete scaffold. When idle, the four side plates and the top plate can be laid down and folded to reduce the volume.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

Detailed Embodiment

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-6 shown, a folding scaffolding includes a base 1 and a top plate 35. The upper plane of the base 1 is rectangular. At the four corner positions of the upper plane of the base 1, a first vertical column 21, a second vertical column 22, a third vertical column 23, and a fourth vertical column 24 are respectively installed. A first side plate 31 is vertically installed between the first vertical column 21 and the second vertical column 22. A second side plate 32 is vertically installed between the third vertical column 23 and the fourth vertical column 24. The second side plate 32 is installed on the opposite side of the first side plate 31. Third side plates 33 and fourth side plates 34 are respectively assembled on both sides of the first side plate 31 and the second side plate 32. Before using the scaffolding, first splice the base 1 with the first side plate 31, the second side plate 32, the third side plate 33, and the fourth side plate 34 to form an upwardly open cuboid frame (as Figure 2 shown), and then install the top plate 35 on the top opening of the cuboid frame to form a complete scaffolding structure (as Figure 1 shown). The top plate 35 is made of high-strength material and is sufficient to support personnel to stand and construct. As Figure 6 shown, when the construction is completed and the scaffolding is idle, the first side plate 31, the second side plate 32, the third side plate 33, the fourth side plate 34, and the top plate 35 can be laid flat and stacked on the base 1, so that the volume of the scaffolding can be quickly reduced, facilitating transportation and storage.

[0024] As Figure 2 shown, the first side plate 31 includes mounting columns 311 and cross beams 312. Two mounting columns 311 and two cross beams 312 are spliced to form a rectangular plate surface. A plug-in space 211 is provided on the first vertical column 21. The first vertical column 21, the second vertical column 22, the third vertical column 23, and the fourth vertical column 24 have the same structure. The first side plate 31 is installed on the first vertical column 21 and the second vertical column 22 through the mounting columns 311. The two mounting columns 311 are respectively inserted into the plug-in spaces 211 of the first vertical column 21 and the second vertical column 22. The first side plate 31 and the second side plate 32 have the same structure. The second side plate 32 is installed on the third vertical column 23 and the fourth vertical column 24 through the mounting columns 311. The two mounting columns 311 of the second side plate 32 are respectively inserted into the plug-in spaces 211 of the third vertical column 23 and the fourth vertical column 24. As Figure 3As shown, a movement pin 314 and a positioning block 315 are connected to the side wall of the mounting post 311. Pin slots 212 are provided on the outer wall surfaces of the first upright post 21, the second upright post 22, the third upright post 23, and the fourth upright post 24. Positioning grooves 213 are provided at the tops of the first upright post 21, the second upright post 22, the third upright post 23, and the fourth upright post 24. After the mounting post 311 is inserted, the movement pin 314 falls into the pin slot 212. The pin slot 212 is a vertical long slot, and the movement pin 314 can move along the length direction of the pin slot 212. The design of the movement pin 314 enables the first side plate 31 and the second side plate 32 to be connected to the corresponding upright posts. This connection is a movable connection. The first side plate 31 and the second side plate 32 can achieve flipping motion and can also achieve lifting motion in the pulled state. After the first side plate 31 and the second side plate 32 are pulled down, the positioning block 315 can descend and snap into the positioning groove 213. At this time, due to the cooperation relationship between the positioning block 315 and the positioning groove 213, the first side plate 31 and the second side plate 32 can be kept in an upright state. Of course, when the first side plate 31 and the second side plate 32 are pulled up, the positioning block 315 can be disengaged from the positioning groove 213, and the first side plate 31 and the second side plate 32 lose the upright positioning, and the first side plate 31 and the second side plate 32 can be flipped down. At this time, the stacking operation of the first side plate 31 and the second side plate 32 can be carried out. Since the pin slot 212 has a vertical length, the stacking height of the first side plate 31 and the second side plate 32 can be correspondingly changed to meet the requirement of successive stacking. When the present utility model is folded up, first stack the third side plate 33 and the fourth side plate 34, and then stack the first side plate 31 and the second side plate 32 (the final outer shape is as shown in Figure 6 ).

[0025] As shown in Figure 2 , the mounting posts 311 of the first side plate 31 and the second side plate 32 both extend upward, so that the top of the mounting post 311 is higher than the cross beam 312. A notch 313 is provided on the upward extension section of the mounting post 311. The size of the notch 313 matches the top plate 35, mainly matching the thickness of the top plate 35, so that the notch 313 can accommodate the smooth insertion of the top plate 35. The top plate 35 is inserted from the direction of the second side plate 32. The notches 313 of the two mounting posts 311 of the first side plate 31 face the insertion direction of the top plate 35 to limit the insertion and positioning of the top plate 35. The notch 313 can catch the top plate 35 to prevent it from bouncing up and down.

[0026] As shown in Figure 2 , a stacking plug 316 is provided at the top of the mounting post 311. Bottom feet 11 are provided at the four corner positions of the lower plane of the base 1. The size of the stacking plug 316 matches the inner hole size of the bottom foot 11. The stacking plug 316 can be inserted into the bottom foot 11 of another scaffold in a matching manner. Under this design, different scaffolds can be stably stacked and elevated to meet the construction height requirements.

[0027] As shown in Figure 4As shown in the figure, the third side plate 33 includes a first plate surface 331, a second plate surface 332 and a hinge 333. The first plate surface 331 and the second plate surface 332 are connected by the hinge 333. The first plate surface 331 and the second plate surface 332 can be folded in half. The second plate surface 332 is flip-connected to the upper plane of the base 1, so that the entire third side plate 33 can be laid down on the upper plane of the base 1. At both sides of the top of the first plate surface 331, locking pins 334 are respectively installed. When the first plate surface 331 is erected, the two locking pins 334 can be respectively inserted into the first side plate 31 and the second side plate 32, and the first plate surface 331 is kept in the erected state by relying on the locking pins 334. At the same time, it also plays a role in connecting and stabilizing the first side plate 31 and the second side plate 32. The third side plate 33 and the fourth side plate 34 have the same structure and are symmetrically installed. When the present utility model is folded up, the third side plate 33 and the fourth side plate 34 are stacked first. First, the locking pins 334 are removed so that they are not connected to the first side plate 31 and the second side plate 32. Then, the third side plate 33 and the fourth side plate 34 are folded and laid down on the upper plane of the base 1. The folding design of the third side plate 33 and the fourth side plate 34 is to reduce the placement plane of the third side plate 33 and the fourth side plate 34. The third side plate 33 and the fourth side plate 34 each occupy half of the upper plane of the base 1.

[0028] As Figure 2 shown, track grooves 335 are opened at the tops of the third side plate 33 and the fourth side plate 34. As Figure 5 shown, two parallel rail bars 351 are connected to the lower plane of the top plate 35. When the top plate 35 is installed, the rail bars 351 respectively fall into the track grooves 335 in one-to-one correspondence. The design of the rail bars 351 and the track grooves 335 enables the top plate 35 to be smoothly pushed in for installation. At the same time, the rail bars 351 and the track grooves 335 can form a positioning effect on the top plate 35, and can prevent the dangerous situation that the top plate 35 moves left and right during use.

[0029] Compared with the traditional scaffolding, the present utility model has fewer components (the present utility model only has a base, four side plates, a top plate and several pin shafts, while the traditional scaffolding has many pipe fittings, lock catches, bolts, etc.), and the disassembly and assembly operations are simpler (the present utility model only needs to complete the operations of flipping the side plates and fixing the pins, while the traditional scaffolding has many on-site splicing operations, installing lock catches and bolts, which require a large amount of labor and time). It can not only meet the construction operation requirements, but also be quickly folded into a small volume state after the construction is completed, which is convenient for handling and storage.

[0030] The above is only the preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.
