Abstract
Description
Technical Field
[0001] This utility model relates to the field of temporary access technology for construction sites, and in particular to a temporary access scaffold for building construction sites. Background Technology
[0002] Scaffolding is an indispensable auxiliary tool on construction sites. During construction, it is often necessary to cross ditches, low-lying areas, or floors of different heights. Temporary access scaffolding plays a crucial role in these situations. It not only provides construction workers with a safe and stable passage platform but also effectively improves work efficiency and reduces construction difficulty.
[0003] On traditional construction sites, workers often use bamboo planks to lay on uneven ground to facilitate walking and transporting materials. However, because bamboo planks are usually long, this presents many challenges during transportation and storage. They take up a lot of space, making storage space scarce. Moreover, due to their length and shape limitations, they are relatively difficult to handle during transport. In addition, bamboo planks are easily affected by humid environments during construction, causing them to deform or rot. This not only affects construction efficiency but may also pose certain safety hazards. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the scaffolding cannot be folded down and reduced in size, which takes up space and is not conducive to transportation. To this end, we propose a temporary access scaffolding for construction sites.
[0005] To achieve the above objectives, this application adopts the following technical solution: a temporary access scaffold for construction sites, comprising scaffold boards, each scaffold board having a base fixedly connected to its bottom, one end of each scaffold board having a base fixedly connected to its bottom, a shaft fixedly connected to the bottom of each scaffold board, and a rotating shell fixedly connected to the bottom of the other scaffold board. The surface of the shaft is rotatably connected to the inner wall of the rotating shell. Rivet rods are fixedly connected to both sides of each scaffold board, and a rotating plate is rotatably connected to the surface of each rivet rod. A threaded rod is threadedly connected to one end of the rotating plate, and two insertion holes are provided on both sides of the other scaffold board.
[0006] Preferably, extension plates are fixedly connected to both sides of the springboard, and pins are inserted through the inner wall of the extension plates.
[0007] Preferably, a connecting rope is fixedly connected to the top of the pin, and the other end of the connecting rope is fixedly connected to one side of the springboard.
[0008] Preferably, a grounding plate is fixedly connected to one side of each of the springboards, and the top of the grounding plate is an inclined surface.
[0009] Preferably, one side of the springboard has several slots, and the other side of the springboard has several inserts fixedly connected.
[0010] Preferably, the top of the scaffolding is fixedly connected with several protruding points, and the inclined surface of the grounding plate is fixedly connected with several protruding strips.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] In this invention, the two springboards can be rotated and adjusted by the rotatable connection between the shaft and the base. When the two springboards are rotated to a horizontal position, the rotating plate is rotated along the rivet rod to align the threaded rod with the insertion hole at the top. The threaded rod is then screwed into the insertion hole, thereby restricting the position of the two springboards and keeping them in a horizontal position. When the two springboards are rotated and folded, the insertion hole is inserted into the insertion hole at the bottom through the threaded rod, fixing the position of the two springboards in the folded state. This allows the springboards to be folded and stored, reducing the space occupied and making it easier to transport and store the device. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0018] Reference Figure 1 and Figure 3As shown, this utility model provides a technical solution: a temporary access scaffold for construction sites, including scaffold boards 1. Each scaffold board 1 has a base 2 fixedly connected to its bottom. One end of the scaffold board 1 is also fixedly connected to the base 2, and a shaft 3 is fixedly connected to its bottom. Another scaffold board 1 has a rotating shell 4 fixedly connected to its bottom. The surface of the shaft 3 is rotatably connected to the inner wall of the rotating shell 4. Rivet rods 5 are fixedly connected to both sides of each scaffold board 1. A rotating plate 6 is rotatably connected to the surface of the rivet rods 5. A threaded rod 7 is threaded to one end of the rotating plate 6. Two insertion holes 8 are provided on both sides of the other scaffold board 1, through which the shaft 3... The rotatable connection with the base 2 allows the two springboards 1 to be rotated and adjusted in angle. When the two springboards 1 are rotated to a horizontal position, the rotating plate 6 is rotated along the rivet rod 5 to align the threaded rod 7 with the insertion hole 8 at the top. The threaded rod 7 is then screwed into the insertion hole 8, thereby restricting the position of the two springboards 1 and keeping them in a horizontal position. When the two springboards 1 are rotated and folded, the insertion hole 8 is inserted into the insertion hole 8 at the bottom through the threaded rod 7, fixing the position of the two springboards 1 in the folded state. This allows the springboards 1 to be folded and stored, reducing the space occupied and making it easier to transport and store the device.
[0019] Reference Figure 1 and Figure 2 As shown in this embodiment: extension plates 9 are fixedly connected to both sides of the plank 1. The inner wall of the extension plate 9 is connected with a pin 10. When the plank 1 is laid flat and placed on a pit or depression in the ground for normal use, the staff inserts the pin 10 into the extension plate 9 and inserts it into the ground. This makes the pin 10 located in the extension plate 9, increasing the stability of the plank 1 after it is placed and preventing the plank 1 from sliding or shifting on the ground, so that the staff can fix the position of the plank 1.
[0020] Reference Figure 1 and Figure 2 As shown in this embodiment: a connecting rope 11 is fixedly connected to the top of the pin 10, and the other end of the connecting rope 11 is fixedly connected to one side of the springboard 1. The pin 10 is connected to the springboard 1 through the springboard 1, so as to prevent the pin 10 from falling and being lost after being pulled out from the inside of the extension plate 9, and to make the connection between the pin 10 and the springboard 1 fixed.
[0021] Reference Figure 1 and Figure 2 As shown in this embodiment: A grounding plate 12 is fixedly connected to one side of the scaffold 1. The top of the grounding plate 12 is an inclined surface. With the grounding plate 12, the scaffold 1 can be placed on the ground for normal use. Objects such as carts can pass through the inclined surface of the grounding plate 12 to pass through the top of the scaffold 1. This makes it easier for workers to walk on the top of the scaffold 1 when moving objects, and prevents the protrusions between the sides of the scaffold 1 and the ground from tripping workers or obstructing carts and similar objects.
[0022] Reference Figure 3 As shown in this embodiment: a number of slots 13 are provided on one side of the springboard 1, and a number of insert plates 14 are fixedly connected to one side of the other springboard 1. When the two springboards 1 are spliced together, the insert plates 14 are inserted into the inner wall of the slots 13 to seal the contact point of the springboards 1, increase the force-bearing area between the two springboards 1, so that the insert plates 14 can spread the load-bearing force on the top of the springboards 1 evenly to the two springboards 1, and prevent the ends of the springboards 1 that are close to each other from deforming and bending after long-term use.
[0023] Reference Figure 1 and Figure 2 As shown in this embodiment: the top of the scaffold 1 is fixedly connected with several protruding points 15, and the inclined surface of the ground floor 12 is fixedly connected with several protruding strips 16. Since the protruding points 15 and the protruding strips 16 are both in a protruding state, the friction between the top of the scaffold 1 and the top of the ground floor 12 is increased. When workers and equipment such as carts pass over the top of the scaffold 1, the dot matrix structure of the protruding points 15 increases the friction between the scaffold 1 and the workers' feet, preventing workers from slipping and falling on the top of the scaffold 1.
[0024] Working principle: The rotational connection between shaft 3 and base 2 allows the two springboards 1 to be adjusted in angle. When the two springboards 1 are rotated to a horizontal position, the rotating plate 6 is rotated along the rivet rod 5 to align the threaded rod 7 with the insertion hole 8 at the top. The threaded rod 7 is then screwed into the insertion hole 8, thus restricting the position of the two springboards 1 and keeping them in a horizontal position. When the two springboards 1 are rotated and folded, the insertion hole 8 is inserted into the insertion hole 8 at the bottom through the threaded rod 7, fixing the position of the two springboards 1 in the folded position. The folded configuration allows the plank 1 to be folded and stored, reducing its space occupation and facilitating the handling and storage of the device. When the plank 1 is laid flat and placed on an uneven surface for normal use, the worker inserts the pins 10 into the extension plate 9, ensuring the pins 10 are positioned within the extension plate 9. This increases the stability of the plank 1 after placement, preventing it from sliding or shifting on the ground, and facilitating the worker's fixation of the plank 1. The plank 1 connects the pins 10 to the plank 1, preventing the pins 10 from being pulled out from inside the extension plate 9. After being removed, the pin 10 is lost, thus securing the connection between the pin 10 and the scaffold 1. The base plate 12 allows the scaffold 1 to be placed on the ground for normal use. Carts and other objects can pass over the top of the scaffold 1 via the inclined surface of the base plate 12, making it easier for workers to walk onto the top of the scaffold 1 when moving objects. This prevents the protrusions between the sides of the scaffold 1 and the ground from tripping workers or obstructing carts and similar objects. When two scaffold 1s are joined, the pin 14 is inserted into the inner wall of the slot 13 to seal the contact point of the scaffold 1s. The increased force-bearing area between the two planks 1 allows the insert 14 to distribute the load on the top of the planks 1 evenly, preventing the ends of the planks 1 that are close to each other from deforming and bending after long-term use. The raised points 15 and raised strips 16 are both raised, thereby increasing the friction between the plank 1 and the top of the base plate 12. When workers and equipment such as carts pass over the top of the plank 1, the dot matrix structure of the raised points 15 increases the friction between the plank 1 and the workers' feet, preventing workers from slipping and falling on the top of the plank 1.
