Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a folding plate device for an external scaffolding. Background Art

[0002] External scaffolding refers to the scaffolding erected outside the building. External scaffolding is widely used. Various ground-based external scaffolding, hanging scaffolding, cantilever scaffolding and hanging scaffolding are generally erected outside the building. External scaffolding is mostly used for exterior wall masonry, facade decoration and reinforced concrete projects.

[0003] Horizontal protection of gaps greater than 15 cm between ground-based external scaffolding and walls has always been a safety shortcoming in the field of exterior wall construction. Most existing ground-based external scaffolding uses waste formwork or nylon mesh bags for horizontal protection, which has low installation and disassembly efficiency, poor protection effect, and is difficult to recycle. It cannot meet the current requirements of green environmental protection and low-carbon economy in construction projects. Utility Model Content

[0004] In order to solve the problems in the background technology, the utility model proposes an external scaffolding folding plate device, which is easy to install and disassemble, has good protection effect, and can be recycled multiple times.

[0005] To solve the above problems, the present invention adopts the following technical solutions: an external scaffolding folding plate device, comprising a plurality of vertical bars and a plurality of horizontal bars, wherein the plurality of vertical bars are arranged in a rectangular array at intervals, and the plurality of horizontal bars are connected one-to-one between two adjacent vertical bars and combined to form a three-dimensional frame structure, and the ends of at least two of the horizontal bars at the same vertical height are rotatably provided with a folding plate structure, and the ends of the folding plate structure away from the horizontal bars are used to be erected on a building, and the folding plate structure comprises an additional horizontal bar, a flap, a plurality of fasteners and a plurality of U-shaped pins, the additional horizontal bar is fixed at the ends of at least two of the horizontal bars, and the plurality of fasteners are fixed at intervals on the additional horizontal bar, one ends of the plurality of U-shaped pins are rotatably inserted into the plurality of fasteners one-to-one, and the other ends of the plurality of U-shaped pins are welded to the side of the flap away from the building.

[0006] Furthermore, the plurality of fasteners each include a bow-shaped member, a connecting member and a fastening bolt, one end of the bow-shaped member is hinged to the connecting member, the other end of the bow-shaped member is connected to the connecting member via the fastening bolt, the middle portion of the bow-shaped member and the connecting member form a channel for the additional horizontal rod to pass through, the connecting member is provided with a mounting hole at the end away from the bow-shaped member, and one end of the U-shaped pin is rotatably passed through the corresponding mounting hole.

[0007] Furthermore, the opening directions of the plurality of U-shaped pins are arranged relative to each other.

[0008] Furthermore, when the end of the flap is overlapped with the building, the upward angle between the flap and the horizontal plane is not less than 15°, and the downward angle between the flap and the horizontal plane is not greater than 85°.

[0009] Furthermore, the flap includes a steel plate mesh, two main rods and multiple secondary rods, the two main rods are arranged in parallel and spaced apart, the multiple secondary rods are welded in parallel and spaced apart between the two main rods, and the steel plate mesh is arranged on the two main rods and the multiple secondary rods.

[0010] Furthermore, the steel plate mesh is set on the two main rods and the plurality of auxiliary rods by rivets or welding.

[0012] Furthermore, the two main rods and the plurality of auxiliary rods are square tubes or round tubes or steel bars.

[0013] The beneficial effects of the present invention are as follows: the present invention installs multiple fasteners, multiple U-shaped pins and flaps by providing additional horizontal rods. When in use, the flaps are rotated to allow the flaps to be tilted and overlapped on the building, so that the gap between the external scaffolding and the building is blocked by the flaps, thereby playing a role of hard protection and isolation. When use is completed, the flaps are rotated around the multiple U-shaped pins to be vertically folded, reducing the space occupied by the flaps for easy storage. Compared with traditional ground-type external scaffolds that mostly use waste formwork or nylon mesh bags for horizontal protection, the present invention can be folded and unfolded for easy operation, not only has a good protection effect, but also can be recycled, and can meet the requirements of current construction projects for green environmental protection and low-carbon economy.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The present invention installs a plurality of fasteners 6, a plurality of U-shaped pins 7, and a flap 5 by providing an additional horizontal rod 4. When in use, the flap 5 can be tilted and overlapped on the building 16 by rotating the plurality of U-shaped pins 7, so as to block the gap between the external scaffolding and the building 16 through the flap 5, thereby playing a role of hard protection and isolation. When use is completed, the flap 5 is rotated around the plurality of U-shaped pins 7 to be vertically folded, reducing the space occupied by the flap 5 for easy storage. Compared with traditional ground-type external scaffolding that mostly uses waste formwork or nylon mesh bags for horizontal protection, the present invention can be folded and unfolded for convenient operation, not only has a good protection effect, but also can be recycled, and can meet the requirements of current construction projects for green environmental protection and low-carbon economy.

[0022] Specifically, such as Figures 1 to 4 As shown, a folding plate device of an external scaffolding includes multiple vertical rods 1 and multiple horizontal rods 2, multiple vertical rods 1 are arranged at intervals in a rectangular array, multiple horizontal rods 2 are connected one-to-one between two adjacent vertical rods 1, and are combined to form a three-dimensional frame structure, the ends of at least two horizontal rods 2 at the same vertical height are rotated to set a folding plate structure 3, the folding plate structure 3 is away from the end of the horizontal rod 2 for being erected on a building 16, the folding plate structure 3 includes an additional horizontal rod 4, a flap 5, multiple fasteners 6 and multiple U-shaped pins 7, the additional horizontal rod 4 is fixed at the ends of at least two of the horizontal rods 2, multiple fasteners 6 are fixed at intervals on the additional horizontal rod 4, one end of multiple U-shaped pins 7 are rotated and inserted into multiple fasteners 6 one-to-one, and the other end of multiple U-shaped pins 7 are welded to the side of the flap 5 away from the building 16.

[0023] Furthermore, the plurality of fasteners 6 each include a bow member 8, a connecting member 9 and a fastening bolt 10, one end of the bow member 8 is hinged to the connecting member 9, and the other end of the bow member 8 is connected to the connecting member 9 via the fastening bolt 10, the middle portion of the bow member 8 and the connecting member 9 encloses a channel 11 for the additional horizontal rod 4 to pass through, and the connecting member 9 is provided with a mounting hole 12 at the end away from the bow member 8, and one end of the U-shaped pin 7 is rotatably passed through the corresponding mounting hole 12.

[0024] Furthermore, the opening directions of the multiple U-shaped pins 7 are set relative to each other. That is, the rod ends of the multiple U-shaped pins 7 are not completely aligned. Since the multiple U-shaped pins 7 can only exit the mounting holes 12 from one side of the rod end, when the opening directions of the multiple U-shaped pins 7 are not completely aligned, the bottom ends of some of the U-shaped pins 7 cannot exit the mounting holes 12. This can ensure the structural stability of the multiple U-shaped pins 7 without installing a limiting structure. Of course, the opening directions of the multiple U-shaped pins 7 can also be set to the same direction. In this case, the rod ends of the U-shaped pins 7 need to have pin holes and limit pins installed to prevent the multiple U-shaped pins 7 from simultaneously falling out of the corresponding mounting holes 12 under the action of external forces, thereby improving the safety of the flap 5.

[0025] Specifically, the distance between the two mutually parallel rod portions of the U-shaped pin 7 is no greater than 40 mm.

[0026] Furthermore, when the end of the flap 5 overlaps the building 16, the upward angle between the flap 5 and the horizontal plane is not less than 15°, and the downward angle between the flap 5 and the horizontal plane is not greater than 85°.

[0027] Furthermore, the flap 5 includes a steel plate mesh 13, two main rods 14 and multiple secondary rods 15, the two main rods 14 are arranged in parallel and spaced apart, and the multiple secondary rods 15 are welded in parallel and spaced apart between the two main rods 14, and the steel plate mesh 13 is arranged on the two main rods 14 and the multiple secondary rods 15.

[0028] Furthermore, the expanded metal 13 is mounted on the two main rods 14 and the plurality of auxiliary rods 15 by rivets or welding.

[0029] Furthermore, the distance between two adjacent auxiliary rods 15 is no more than 500 mm.

[0030] Furthermore, the two main rods 14 and the plurality of auxiliary rods 15 are square tubes or round tubes or steel bars.

[0031] Specifically, the number of the folding plate structures 3 can be one or more, and the number of the folding plate structures 3 can be flexibly set according to the height of the building 16. When the number of the folding plate structures 3 exceeds one, the vertical spacing between the two adjacent folding plate structures 3 in the upper and lower directions is not greater than 10m, wherein the flap 5 of the topmost folding plate structure 3 is rotated downward and erected on the top of the building 16, and the flap 5 of the bottom folding plate structure 3 is rotated upward and erected on the side of the building 16.

[0032] When the present invention is used, the flap 5 is first rotated by rotating the multiple U-shaped pins 7 so that the flap 5 can be tilted and overlapped on the building 16, thereby blocking the gap between the external scaffolding and the building 16 through the flap 5, thereby providing a hard protective isolation function. When the use is completed, the flap 5 is rotated around the multiple U-shaped pins 7 to be folded vertically, reducing the space occupied by the flap 5 and facilitating storage. Compared with traditional ground-type external scaffolding that mostly uses waste formwork or nylon mesh bags for horizontal protection, the present invention can be folded and unfolded for convenient operation, not only has a good protective effect, but also can be recycled, which can meet the current requirements of green environmental protection and low-carbon economy in construction projects.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
