Description

Technical Field

[0001] This application relates to the technical field of external scaffolding, and in particular to an external scaffolding. Background Technology

[0002] Scaffolding refers to various supports erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It is mainly used for construction workers to move up and down, for external safety netting, and for the installation of components at heights. Scaffolding is typically made of materials such as bamboo, wood, steel pipes, or composite materials.

[0003] A Chinese patent with publication number CN212053668U discloses a disc-lock type external scaffolding, which includes a vertically arranged support and a horizontally arranged connecting rod. A connecting plate is coaxially fixedly connected to the outer wall of the support. The connecting plate has multiple connecting grooves that penetrate the connecting plate along the height direction of the connecting plate and are distributed circumferentially along the connecting plate. Connecting blocks are fixedly connected to both ends of the connecting rod. The connecting blocks have slots that engage with the connecting plate radially.

[0004] Regarding the aforementioned technologies, it has been found that existing external scaffolding requires on-site assembly using different pole groups. Due to the large number of components, assembly is often time-consuming and labor-intensive, and the four-legged support method often poses a risk of tipping over. Utility Model Content

[0005] To facilitate quick assembly and use and increase safety, this application provides an external scaffolding.

[0006] The external scaffolding provided in this application adopts the following technical solution:

[0007] An external scaffold includes a main frame, which comprises a base frame, a first side frame, and a second side frame. The first and second side frames are respectively installed at both ends of the base frame and are rotatably connected to the base frame. Equipment frames are also installed at the top of the first and second side frames, and the two ends of the equipment frames are rotatably connected to the first and second side frames, respectively. Auxiliary supports are installed on both the first and second side frames and are fixedly connected to the first and second side frames. The upper end of the first side frame and the lower end of the second side frame are connected by a positioning bracket, and the two ends of the positioning bracket are respectively connected to the first and second side frames by bolts.

[0008] By adopting the above technical solution, the main frame is designed as a structure in which the bottom frame, the first side frame, and the second side frame cooperate. When easy to use, the first side frame and the second side frame can be installed at both ends of the bottom frame, and the equipment frame can be installed at the head of the first side frame and the second side frame. The equipment frame, the first side frame, the bottom frame, and the second side frame are all rotatably connected. In this way, the equipment frame, the first side frame, the bottom frame, and the second side frame can form a corresponding frame structure. When needed, the equipment frame, the first side frame, the bottom frame, and the second side frame can be flipped to a right angle position to form a rectangular structure. When not in use, they can be flipped and folded together for easy storage and transportation. When needed, when the equipment frame, the first side frame, the bottom frame, and the second side frame are flipped to form a rectangular structure, the two opposite corners of the rectangle can be connected to each other through an auxiliary bracket. This ensures that the equipment frame, the first side frame, the bottom frame, and the second side frame are fixed together, ensuring stable use of the equipment. In this way, the operator can stand and use the equipment frame.

[0009] Optionally, both the first side frame and the second side frame include two vertical bars and several horizontal bars, with the horizontal bars evenly installed between the two vertical bars and fixedly connected to the vertical bars.

[0010] By adopting the above technical solution, the first side frame and the second side frame are designed as a structure in which two vertical bars and several horizontal bars cooperate. When it is easy to use, the two vertical bars can be connected to each other by several horizontal bars to ensure the stability of the first side frame and the second side frame during use. At the same time, the setting of the horizontal bars can also ensure the stable connection and use of the seat plate.

[0011] Optionally, a set of casters is installed on the lower end face of the vertical rod, and the set of casters is fixedly connected to the vertical rod.

[0012] By adopting the above technical solution and fixing the universal wheel assembly to the lower end face of the vertical rod, the entire equipment can be flexibly moved and used in different positions through four cooperating universal wheel assemblies, increasing the flexibility of equipment use.

[0013] Optionally, the device frame includes a base plate and a top frame, the top frame being mounted on the upper surface of the base plate and fixedly connected to the base plate.

[0014] By adopting the above technical solution, and by designing the equipment frame as a structure in which the seat plate and the top frame cooperate, it is easy for construction workers to stand and use when it is easy to use. At the same time, by installing the top frame on the seat plate, it is easier to place the corresponding items in the equipment frame for use when it is easy to use.

[0015] Optionally, connecting rings that rotatably engage with the crossbar are installed on the four corners of the lower end face of the seat plate, and the connecting rings are fixedly connected to the seat plate.

[0016] By adopting the above technical solution, connecting rings are installed on the four corners of the lower end face of the seat plate. When in use, the connecting rings can be rotated and engaged with the crossbar. This ensures that both ends of the seat plate are connected to the first side frame and the second side frame respectively, which facilitates rotational connection between them.

[0017] Optionally, the auxiliary support includes diagonal braces and a central frame. The heads of the diagonal braces and the central frame are provided with connecting frames that are connected to the vertical rods. The connecting frames are rotatably connected to both the diagonal braces and the central frame. The lower end of the central frame is also rotatably fitted with a mating ring that is fixed to the diagonal braces.

[0018] By adopting the above technical solution, the auxiliary support is designed as a structure that combines diagonal braces and a central frame. When in use, it can be installed on the vertical members of the first or second side frame using the diagonal braces and the central frame. During installation, it can be clamped and fixed to the vertical members using a connecting frame. This facilitates the use of the inclined diagonal braces to assist in supporting the vertical members, which can effectively reduce the possibility of the vertical members tilting or overturning. Furthermore, by installing a mating ring at the lower end of the central frame, it is easy to stably install it on the diagonal braces using the mating ring.

[0019] Optionally, the connecting frame includes a first clamping plate, a second clamping plate, a connecting screw, and a clamping bend plate. The first clamping plate and the second clamping plate are arranged opposite to each other. The connecting screw is inserted and installed on the first clamping plate and the second clamping plate. The clamping bend plate is threadedly connected to the connecting screw, and a safety nut is also installed on the connecting screw.

[0020] By adopting the above technical solution, the structure of the connecting frame is designed to ensure that the first and second clamping plates can be clamped relative to each other on the vertical rod during use. Then, the connecting screw passes through the first and second clamping plates to connect them to each other. By installing a clamping plate on the connecting screw, the distance between the first and second clamping plates can be adjusted by rotating the position of the clamping plate on the connecting screw during use, thereby ensuring stable clamping by the first and second clamping plates. By installing a matching safety nut on the connecting screw, the clamping plate is limited by the safety nut, ensuring safer use of the clamping plate.

[0021] Optionally, an anti-slip base is installed on the lower end face of the diagonal brace, and the anti-slip base is fixedly connected to the diagonal brace.

[0022] By adopting the above technical solution, and by installing an anti-slip base on the lower end of the diagonal brace, it can be stably supported on the ground when in use, ensuring that the diagonal brace can support the first and second side frames.

[0023] In summary, this application includes at least one of the following beneficial technical effects: This application designs the main frame as a structure in which the bottom frame, the first side frame, and the second side frame cooperate, and then combines them with the equipment frame to form a rectangular structure. Moreover, the bottom frame, the first side frame, the equipment frame, and the second side frame are rotatably connected to each other, which makes it convenient to fold and store when not in use. When needed, it can be flipped into a rectangle and fixed by the positioning bracket, ensuring that both use and storage are very convenient. At the same time, in order to further increase the stability of use, corresponding auxiliary brackets are installed on the first side frame and the second side frame to reduce the shaking and tipping of the first side frame and the second side frame, thereby increasing the safety of equipment use.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses an external scaffolding. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, an external scaffold includes a main frame 1, which includes a bottom frame 11, a first side frame 12, and a second side frame 13. The first side frame 12 and the second side frame 13 are respectively installed at both ends of the bottom frame 11 and are rotatably connected to the bottom frame 11. Equipment frames 2 are also installed at the heads of the first side frames 12 and the second side frames 13. The two ends of the equipment frames 2 are respectively rotatably connected to the first side frames 12 and the second side frames 13. Auxiliary supports 3 are installed on both the first side frames 12 and the second side frames 13. The auxiliary supports 3 are fixedly connected to the first side frames 12 and the second side frames 13. The upper end of the first side frame 12 and the lower end of the second side frame 13 are connected by a positioning bracket 4, and the two ends of the positioning bracket 4 are respectively connected to the first side frame 12 and the second side frame 13 by bolts. By designing the main frame 1 as a structure in which the bottom frame 11, the first side frame 12, and the second side frame 13 cooperate, it is easy to use by installing the first side frame 12 and the second side frame 13 at both ends of the bottom frame 11, and installing the equipment frame 2 at the head of the first side frame 12 and the second side frame 13. The equipment frame 2, the first side frame 12, the bottom frame 11, and the second side frame 13 are all rotatably connected. In this way, the equipment frame 2, the first side frame 12, the bottom frame 11, and the second side frame 13 can form a corresponding frame structure, ensuring that when needed, the equipment frame 2, the first side frame 12, the bottom frame 11, and the... The four components of the second side frame 13 are flipped to right angles to form a rectangular structure. When not in use, they can be folded together for easy storage and transportation. When needed, when the equipment frame 2, the first side frame 12, the bottom frame 11, and the second side frame 13 are flipped to form a rectangular structure, the two opposite corners of the rectangle can be connected by the auxiliary bracket 3. This ensures that the equipment frame 2, the first side frame 12, the bottom frame 11, and the second side frame 13 are fixed together, ensuring stable use of the equipment. The operator can then stand and use the equipment from the equipment frame 2.

[0032] Reference Figure 1As shown, both the first side frame 12 and the second side frame 13 include two vertical rods 121 and several horizontal rods 122. The horizontal rods 122 are evenly installed between the two vertical rods 121 and are fixedly connected to the vertical rods 121. By designing the first side frame 12 and the second side frame 13 into a structure with two vertical rods 121 and several horizontal rods 122, the two vertical rods 121 can be connected to each other by the several horizontal rods 122 when in use, ensuring the stability of the first side frame 12 and the second side frame 13 during use. At the same time, the horizontal rods 122 also ensure the stable connection of the seat plate 21. A set of universal wheels 123 is installed on the lower end face of the vertical rod 121 and is fixedly connected to the vertical rod 121. By fixing the set of universal wheels 123 on the lower end face of the vertical rod 121, the entire equipment can be flexibly moved to different positions by four cooperating sets of universal wheels 123, increasing the flexibility of the equipment.

[0033] Reference Figure 1 and Figure 2 As shown, the equipment frame 2 includes a seat plate 21 and a top frame 22. The top frame 22 is installed on the upper surface of the seat plate 21 and is fixedly connected to the seat plate 21. By designing the equipment frame 2 with a structure in which the seat plate 21 and the top frame 22 cooperate, it is easy for construction workers to stand and use the equipment when it is easy to use. At the same time, by installing the top frame 22 on the seat plate 21, it is easier to place items on the equipment frame 2 when it is easy to use. Connecting rings 211 that rotate with the crossbar 122 are installed on the four corners of the lower surface of the seat plate 21. The connecting rings 211 are fixedly connected to the seat plate 21. By installing connecting rings 211 on the four corners of the lower surface of the seat plate 21, it is convenient to use the equipment frame 211 to rotate with the crossbar 122. This ensures that both ends of the seat plate 21 are respectively connected to the first side frame 12 and the second side frame 13, which allows for rotational connection between them.

[0034] Reference Figure 3 , Figure 4 and Figure 5As shown, the auxiliary support 3 includes a diagonal brace 31 and a middle frame 32. The heads of the diagonal brace 31 and the middle frame 32 are provided with connecting brackets 33 that connect to the vertical rod 121. The connecting brackets 33 are rotatably connected to both the diagonal brace 31 and the middle frame 32. A mating ring 321, fixed to the diagonal brace 31, is also rotatably installed at the lower end of the middle frame 32. By designing the auxiliary support 3 as a structure where the diagonal brace 31 and the middle frame 32 cooperate, it can be easily installed on the vertical rod 121 of the first side frame 12 or the second side frame 13 using the diagonal brace 31 and the middle frame 32. During installation, the connecting brackets 33 can clamp and fix the vertical rod 121. This facilitates the use of the inclined diagonal brace 31 to assist in supporting the vertical rod 121, effectively reducing the possibility of the vertical rod 121 tilting or tipping over. Furthermore, by installing the mating ring 321 at the lower end of the middle frame 32, it is easy to stably install it on the diagonal brace 31. The connecting frame 33 includes a first clamping plate 331, a second clamping plate 332, a connecting screw 333, and a clamping bending plate 334. The first clamping plate 331 and the second clamping plate 332 are arranged opposite to each other. The connecting screw 333 is inserted and installed on the first clamping plate 331 and the second clamping plate 332. The clamping bending plate 334 is threadedly connected to the connecting screw 333, and a safety nut 335 is also installed on the connecting screw 333. The connecting frame 33 is structurally designed to ensure that the first clamping plate 331 and the second clamping plate 332 can be clamped relative to each other on the vertical rod 121 during use. A connecting screw 333 passes through the first clamping plate 331 and the second clamping plate 332 to connect them. A clamping plate 334 is installed on the connecting screw 333. During use, the position of the clamping plate 334 on the connecting screw 333 can be adjusted to change the distance between the first clamping plate 331 and the second clamping plate 332, ensuring stable clamping. A matching safety nut 335 is installed on the connecting screw 333 to limit the movement of the clamping plate 334, ensuring safer use. An anti-slip base 311 is installed on the lower end face of the diagonal brace 31, and the anti-slip base 311 is fixedly connected to the diagonal brace 31. By installing an anti-slip base 311 on the lower end face of the diagonal brace 31, it can be stably supported on the ground when in use, ensuring that the first side frame 12 and the second side frame 13 are supported by the diagonal brace 31.

[0035] The implementation principle of an external scaffolding according to an embodiment of this application is as follows: During actual transportation, the equipment frame 2, the first side frame 12, the bottom frame 11, and the second side frame 13 can be folded and stored for easier loading and transportation. When the scaffolding is needed, the equipment frame 2, the first side frame 12, the bottom frame 11, and the second side frame 13 can be flipped up into a rectangular structure. Then, the positioning diagonal frame 4 can be fixedly installed on the two opposite corners of the rectangle. After assembly, the auxiliary support 3 can be installed. The auxiliary support 3 is clamped and fixed to the four diagonal braces 31 by the connecting frame 33, which can ensure the stable use of the equipment.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
