Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a scaffold. Background Art

[0002] Scaffolding is an indispensable part of construction projects and plays a vital role in auxiliary and safety assurance. At the construction site, it not only serves as a working platform for workers to operate, but also is used to solve vertical and horizontal transportation problems. Common types of scaffolding include pole scaffolding, portal scaffolding and hanging scaffolding. Pole scaffolding is widely used because of its simple structure and strong adaptability. The portal scaffolding has become a common choice in construction due to its standardized, reasonable structure and efficient and safe assembly and disassembly process. The hanging scaffolding is suitable for construction operations under specific conditions, such as cantilever operations. In summary, as an important part of construction, the scientific and standardized application of scaffolding is crucial to engineering safety.

[0003] The top layer of the existing scaffolding is a steel mesh structure. The purpose of setting up the steel mesh structure is to provide support while reducing its own weight, thereby reducing the pressure on the lower support. However, there are no guardrails around the steel mesh, which cannot provide safety protection for construction workers.

[0004] Therefore, it is necessary to provide a scaffold to solve the above technical problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a scaffolding to solve the problem that the top layer of the current scaffolding is a steel mesh structure. The purpose of setting the steel mesh structure is to provide support while reducing its own weight, thereby reducing the pressure on the lower support. However, there are no guardrails around the steel mesh, which cannot provide safety protection for construction workers.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A scaffold comprises: a support frame;

[0008] The top of the support frame is connected to the mounting plate by bolts. The mounting plate is a U-shaped structure as a whole, and a rectangular opening is opened in the middle of its top surface. The top surface of the mounting plate is installed and connected to the support plate by bolts. The middle section of the support plate is located above the rectangular opening. A ladder is provided at the bottom of the mounting plate, and guardrails are bolted around the top of the mounting plate.

[0009] In one embodiment, the support plate is a hollow steel layer plate with an inlet in the middle. The inlet is generally circular in structure with a diameter larger than the required width for an adult male to enter. The inlet is opened at the center of the support plate and the rectangular opening.

[0010] In one embodiment, a mounting rod is installed inside the rectangular opening, and mounting grooves are opened on the front end surfaces of both sides of the mounting rod. The top two sides of the ladder are plugged into the mounting grooves, and the middle section of the inclined section of the ladder is directly below the entrance.

[0011] In one embodiment, the support plate is composed of two plates with the same structure and arranged at opposite positions. Slots are provided on both sides of the support plate at the inlet. There are four slots arranged in a rectangular array. The inlet is connected to the baffle through the slots.

[0012] In one embodiment, the baffle is an overall cylindrical structure, and its diameter is consistent with the inner diameter of the inlet. Insert blocks are installed on both sides of the baffle, and the insert blocks are matched with the slots. A handle is installed on the top surface of the baffle, and the baffle is made of aluminum alloy as a whole.

[0013] The beneficial effects of the utility model are as follows:

[0014] (1) The utility model installs the support plate, the mounting plate and the support frame, and then inserts the top of the ladder into the mounting groove to preliminarily fix the ladder. A person manually climbs up the ladder to the top of the ladder, and screws fixing bolts into the ladder and the mounting groove to fix the ladder. The construction personnel enter the entrance through the ladder, and then enter the top surface of the support plate from the entrance to perform operations, thereby avoiding the existing climbing method of climbing the support frame sideways, which will cause the center of gravity of the entire device to shift and the stability to be poor.

[0015] (2) The utility model allows construction workers to start working after entering the top surface of the support plate from the entrance, and seal the baffle at the entrance to prevent construction workers from accidentally stepping on and falling. During the operation, if a part or tool is needed temporarily, the baffle is moved out by the handle, and another construction worker takes the tool and climbs up the ladder to the entrance, and then sends the tool from the entrance into the upper space for the construction worker to take. The setting of the entrance not only serves as a manual channel, but also serves as a tool delivery channel. There is no need for workers to stick out half of their body to take tools from the outside of the support frame, thereby improving the safety of the overall device.

[0016] (3) The utility model has a support plate composed of two plates with the same structure and relatively opposite positions. The purpose is to prevent the hollow mesh layer of the support plate from becoming dented or broken after being used for a long time. Replacing the entire plate is wasteful and inconvenient to repair. The assembled structure helps to reduce maintenance costs and at the same time helps to improve the convenience of carrying.

The top surface of the mounting plate 2 is installed and connected to the support plate 3 by bolts. The middle section of the support plate 3 is located above the rectangular opening 23. A ladder 5 is provided at the bottom of the mounting plate 2. Guardrails 4 are bolted around the top of the mounting plate 2. The setting of the guardrails 4 helps to protect the construction workers.

[0025] Preferably, in one embodiment, Figure 2-Figure 3 As shown, the support plate 3 is a hollow steel layer plate, with an entrance 31 in the middle. The entrance 31 is a circular structure as a whole, and its diameter is larger than the required width for an adult male to enter. The entrance 31 is opened at the center of the support plate 3 and the rectangular opening 23. The purpose is to avoid the existing climbing method of climbing the support frame 1 sideways, which will cause the center of gravity of the whole device to shift and the stability to be poor.

[0026] Preferably, in one embodiment, Figure 2-Figure 3As shown, a mounting rod 21 is installed inside the rectangular opening 23, and mounting grooves 22 are provided on the front end surfaces of both sides of the mounting rod 21. The top sides of the ladder 5 are plugged into the mounting grooves 22, and the middle section of the inclined section of the ladder 5 is directly below the entrance 31. During work, after the support plate 3, the mounting plate 2 and the support frame 1 are installed, the top of the ladder 5 is inserted into the mounting groove 22 to preliminarily fix the ladder 5. Manual workers climb up the ladder 5 to the top of the ladder 5, screw fixing bolts into the ladder 5 and the mounting groove 22 to fix the ladder 5, and the construction workers enter the entrance 31 from the ladder 5, and enter the top surface of the support plate 3 from the entrance 31 to work.

[0027] Preferably, in one embodiment, Figure 3-Figure 4 As shown, the support plate 3 is composed of two plates with the same structure and relatively set positions. The purpose is that after being used for a long time, the hollow mesh layer of the support plate 3 will be dented or broken. Replacing the entire piece is wasteful and maintenance is inconvenient. The assembled structure helps to reduce maintenance costs. At the same time, the assembled structure helps to improve the convenience of carrying. Slots 32 are provided on both sides of the inlet 31 of the support plate 3. Four slots 32 are arranged in a rectangular array. The inlet 31 is connected to the baffle 6 through the slots 32.

When working, the construction personnel start working after entering the top surface of the support plate 3 from the inlet 31, and seal the baffle 6 at the inlet 31 to prevent the construction personnel from accidentally stepping on and falling. During the operation, if parts and tools are needed temporarily, the baffle 6 is removed through the handle 62, and another construction personnel takes the tools and climbs up the ladder 5, and climbs to the inlet 31, and sends the tools from the inlet 31 into the upper space, and the construction personnel take them. The setting of the inlet 31 is not only a manual channel, but also a tool delivery channel. There is no need to manually stick out half of the body to take tools from the outside of the support frame 1, which improves the safety of the overall device.

[0029] Working principle of this utility model:

[0030] After the support plate 3 is installed with the mounting plate 2 and the support frame 1, the top of the ladder 5 is inserted into the mounting groove 22 to preliminarily fix the ladder 5. The worker manually climbs up to the top of the ladder 5, screws the fixing bolts into the ladder 5 and the mounting groove 22, and fixes the ladder 5. The construction worker enters the inside of the entrance 31 through the ladder 5, and enters the top surface of the support plate 3 from the inside of the entrance 31 to work. The construction worker starts working after entering the top surface of the support plate 3 from the entrance 31, and blocks the baffle 6 at the entrance 31 to prevent the construction worker from accidentally stepping on and falling. During the operation, if a part tool is needed temporarily, the baffle 6 is removed by the handle 62, and another construction worker climbs up the ladder 5 after taking the tool, and climbs to the entrance 31, and sends the tool from the entrance 31 into the upper space, and the construction worker takes it. The setting of the entrance 31 is not only an artificial channel, but also a tool conveying channel at the same time. There is no need to manually stretch out half of the body to take the tool from the outside of the support frame 1, thereby improving the safety of the overall device.
