Abstract
Description
Technical Field
[0001] This utility model relates to the field of scaffolding technology, and in particular to a prefabricated scaffolding for construction engineering. Background Technology
[0002] Scaffolding refers to various supports erected on construction sites to facilitate worker operations and solve vertical and horizontal transportation. It is a common term in the construction industry, referring to the use of scaffolding on construction sites for exterior walls, interior decoration, or high-ceilinged areas where direct construction is not possible. It is mainly used for construction workers to move up and down, for external safety netting, and for the installation of components at height.
[0003] In existing construction projects, prefabricated scaffolding is mostly assembled by using multiple steel pipes together with screws to form a complete frame. Then, the footboards are fixed to the frame with screws for construction workers to stand and work on.
[0004] However, when the platform is placed against the wall using a frame, a gap may exist between the platform and the wall. This could cause a worker to accidentally step into the gap during operation, resulting in loss of balance and a fall. Utility Model Content
[0005] The technical problem this utility model aims to solve is that when the pedal is placed on one side of the wall via the frame, there will be a certain gap between the pedal and the wall, which may cause personnel to accidentally step into the gap during operation, resulting in loss of balance and fall.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a prefabricated scaffold, including a frame body, a step is provided on one side of the frame body, a filling device is provided on one side of the step to fill the gap between the step and the wall, and a stabilizing device is provided at the bottom of the frame body to support and reinforce the bottom of the frame body.
[0007] The effect achieved by the above components is as follows: First, multiple steel pipes are assembled together with screw connectors to form a complete frame. Then, the footboard is fixed to the frame with screw connectors for construction workers to stand and work on.
[0008] Preferably, the filling device includes a slide rail, which is fixedly connected to a pedal. A rectangular hole is provided on one side of the slide rail, and a rectangular rod is slidably connected to the inner wall of the slide rail. An extension plate is fixedly connected to one side of the rectangular rod, and a first screw is fixedly connected to one side of the rectangular rod. The first screw is disposed inside the rectangular hole, and a threaded ring is threaded onto the surface of the first screw. The surface of the threaded ring is larger than the inner wall of the rectangular hole.
[0009] The effect achieved by the above-mentioned components is as follows: By setting up the extension device, the frame and the pedal are first placed close to the wall. At this time, the extension plate is manually moved, causing the extension plate to drive the rectangular rod to slide along the inside of the slide rail. This causes the rectangular rod to drive the first screw to move along the inside of the rectangular hole. When the extension plate moves to the position where it is in contact with the wall surface, the screw hole ring is manually rotated, causing the screw hole ring to move along the surface of the first screw. This causes the screw hole ring to move to the position where it presses against the surface of the slide rail, fixing the rectangular rod and the extension plate in place. This fixes the extension plate in the gap between the pedal and the wall, filling the gap between the pedal and the wall. This reduces the risk of personnel accidentally stepping into the gap between the pedal and the wall during operation, causing them to lose their balance and fall, thus improving the safety of personnel during operation.
[0010] Preferably, a plurality of auxiliary blocks are fixedly connected to the surface of the screw hole ring, and the plurality of auxiliary blocks are arranged at equal intervals.
[0011] The effect achieved by the above components is that by setting up the auxiliary block, the auxiliary block can intercept the hand, reducing the chance of the hand slipping when the person manually rotates the screw hole ring.
[0012] Preferably, a baffle is fixedly connected to the end of the first screw away from the rectangular rod, and the surface of the baffle is larger than the inner wall of the screw hole ring.
[0013] The effect achieved by the above components is that by setting up a baffle, the baffle can intercept the screw ring during the movement, reducing the possibility of the screw ring accidentally detaching from the surface of the first screw.
[0014] Preferably, a handle is fixedly connected to one side of the extension plate, and the inner side of the handle is provided with multiple anti-slip protrusions.
[0015] The effect achieved by the above components is that by setting a handle, the handle can provide a point of leverage for personnel, allowing personnel to easily move the extension plate by manually moving the handle.
[0016] Preferably, a T-shaped plate is fixedly connected to one side of the extension plate, and a T-shaped groove is provided on one side of the pedal. The surface of the T-shaped plate is slidably connected to the inner wall of the T-shaped groove.
[0017] The effects achieved by the above components are as follows: by setting the T-shaped plate and T-shaped groove, the T-shaped plate can be located inside the T-shaped groove to assist in limiting the extension plate, reducing the wobbling of the extension plate during use. At the same time, the T-shaped plate can fill the height difference between the extension plate and the pedal surface, making the height between the pedal and the extension plate as level as possible, which is convenient for people to stand and walk.
[0018] Preferably, the stabilizing device includes a screw hole plate, which is fixedly connected to the frame. A second screw is threadedly connected to the inner wall of the screw hole plate. A conical block is fixedly connected to one end of the second screw, and an operating rod is fixedly connected to the end of the second screw away from the conical block.
[0019] The effect achieved by the above-mentioned components is as follows: By setting up a stabilizing device, the frame is first placed on the ground. At this time, the operating lever is manually rotated, causing the operating lever to drive the second screw to rotate. The second screw moves up and down along the inside of the screw hole plate, causing the second screw to drive the conical block to move up and down. When the conical block moves to the position of contact with the ground, the ground limits the conical block. During the rotation of the second screw, the screw hole plate moves up and down, causing the screw hole plate to drive the frame to move up and down, thus providing auxiliary support for the bottom of the frame. This reduces the height difference between the left and right sides when the frame is placed on uneven ground, which causes the frame to sway during use, and improves the stability of the frame.
[0020] Preferably, a reinforcing block is fixedly connected to one side of the screw plate, and the reinforcing block is fixedly connected to the frame.
[0021] The effect achieved by the above components is that by setting up reinforcing blocks, the connection between the screw hole plate and the frame can be strengthened, reducing the possibility of the screw hole plate separating from the frame during use.
[0022] The beneficial effects of this utility model are:
[0023] By installing an extension device, the gap between the pedal and the wall can be filled, reducing the risk of personnel accidentally stepping into the gap while working on the pedal, causing them to lose their balance and fall, thus improving the safety of personnel during operation.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Figure 1-4 The prefabricated scaffolding for construction projects shown includes a frame 1, a step 2 on one side of the frame 1, a filling device 3 on one side of the step 2 to fill the gap between the step 2 and the wall, and a stabilizing device 4 at the bottom of the frame 1 to support and reinforce the bottom of the frame 1. First, multiple steel pipes are assembled together with screw connectors to form a complete frame 1. Then, the step 2 is fixed to the frame 1 with screw connectors for construction workers to stand and work.
[0033] Figure 2 and Figure 3The filling device 3 shown includes a slide rail 31, which is fixedly connected to the pedal 2. A rectangular hole 32 is provided on one side of the slide rail 31. A rectangular rod 34 is slidably connected to the inner wall of the slide rail 31. An extension plate 39 is fixedly connected to one side of the rectangular rod 34. A first screw 35 is fixedly connected to one side of the rectangular rod 34. The first screw 35 is disposed inside the rectangular hole 32. A threaded ring 36 is threaded onto the surface of the first screw 35. The surface of the threaded ring 36 is larger than the inner wall of the rectangular hole 32. By setting the extension device, the frame 1 together with the pedal 2 is first placed near the wall. At this time, the extension plate 39 is manually moved, so that the extension plate 39 drives the rectangular rod 34 along the slide rail 31. The internal sliding mechanism causes the rectangular rod 34 to drive the first screw 35 to move along the inside of the rectangular hole 32. When the extension plate 39 moves to the position where it is in contact with the wall surface, the screw hole ring 36 is manually rotated, causing the screw hole ring 36 to move along the surface of the first screw 35. The screw hole ring 36 moves to the position of pressing the surface of the slide rail 31 to fix the rectangular rod 34 and the extension plate 39 in position. This fixes the extension plate 39 in the gap between the pedal 2 and the wall, thus filling the gap between the pedal 2 and the wall. This reduces the risk of personnel accidentally stepping into the gap between the pedal 2 and the wall during operation, which could cause them to lose their balance and fall, and improves the safety of personnel during operation.
[0034] Figure 2 and Figure 3 Multiple auxiliary blocks 37 are fixedly connected to the surface of the screw ring 36 shown. The multiple auxiliary blocks 37 are arranged at equal distances. By setting the auxiliary blocks 37, the auxiliary blocks 37 can intercept the hand and reduce the possibility of the hand slipping when the person manually rotates the screw ring 36. A baffle 38 is fixedly connected to the end of the first screw 35 away from the rectangular rod 34. The surface of the baffle 38 is larger than the inner wall of the screw ring 36. By setting the baffle 38, the baffle 38 can intercept the screw ring 36 during the movement and reduce the possibility of the screw ring 36 accidentally detaching from the surface of the first screw 35.
[0035] Figure 2 and Figure 3A handle 311 is fixedly connected to one side of the extension plate 39 shown. The inner side of the handle 311 is provided with multiple anti-slip protrusions. By setting the handle 311, the handle 311 can provide a point of leverage for the personnel, so that the personnel can move the extension plate 39 conveniently by manually moving the handle 311. A T-shaped plate 310 is fixedly connected to one side of the extension plate 39. A T-shaped groove 33 is opened on one side of the pedal 2. The surface of the T-shaped plate 310 is slidably connected to the inner wall of the T-shaped groove 33. By setting the T-shaped plate 310 and the T-shaped groove 33, the T-shaped plate 310 can be located inside the T-shaped groove 33 to assist in limiting the extension plate 39 and reduce the shaking of the extension plate 39 during use. At the same time, the T-shaped plate 310 can fill the height difference between the extension plate 39 and the surface of the pedal 2, so that the height between the pedal 2 and the extension plate 39 is as level as possible, which is convenient for the personnel to stand and walk.
[0036] Figure 4 The stabilizing device 4 shown includes a screw plate 41, which is fixedly connected to the frame 1. A second screw 42 is threaded onto the inner wall of the screw plate 41. A conical block 43 is fixedly connected to one end of the second screw 42, and an operating rod 44 is fixedly connected to the other end of the second screw 42 away from the conical block 43. By setting up the stabilizing device 4, the frame 1 is first placed on the ground. At this time, the operating rod 44 is manually rotated, causing the operating rod 44 to drive the second screw 42 to rotate, so that the second screw 42 moves up and down along the inside of the screw plate 41. The movement causes the second screw 42 to drive the conical block 43 to move up and down. When the conical block 43 moves to the position of contact with the ground, the ground limits the conical block 43. During the rotation of the second screw 42, the screw hole plate 41 moves up and down, which in turn drives the frame 1 to move up and down, thus providing auxiliary support to the bottom of the frame 1. This reduces the height difference between the left and right sides when the frame 1 is placed on uneven ground, which can cause the frame 1 to shake during use, and improves the stability of the frame 1.
[0037] Figure 4 A reinforcing block 45 is fixedly connected to one side of the screw hole plate 41 shown. The reinforcing block 45 is fixedly connected to the frame 1. By setting the reinforcing block 45, the connection between the screw hole plate 41 and the frame 1 can be strengthened, reducing the possibility of the screw hole plate 41 separating from the frame 1 during use.
[0038] Working principle: First, multiple steel pipes are assembled together using screw connectors to form a complete frame 1. Then, the footboard 2 is fixed to the frame 1 using screw connectors for construction workers to stand on. At this time, the frame 1 and footboard 2 are placed close to the wall. Then, the handle 311 is manually moved, causing the handle 311 to move the extension plate 39. The extension plate 39 causes the rectangular rod 34 to slide along the inside of the slide rail 31. The rectangular rod 34 causes the first screw 35 to move along the inside of the rectangular hole 32. When the extension plate 39 moves to the position where it is in contact with the wall surface, the screw hole ring 36 is manually rotated, causing the screw hole ring 36 to move along the surface of the first screw 35. The screw hole ring 36 moves to the position where it presses against the surface of the slide rail 31, fixing the rectangular rod 34 and the extension plate 39 in place. This fixes the extension plate 39 in the gap between the footboard 2 and the wall, thus filling the gap between the footboard 2 and the wall.
[0039] First, place the frame 1 on the ground. Then, manually rotate the operating lever 44, causing the operating lever 44 to drive the second screw 42 to rotate. This causes the second screw 42 to move up and down along the inside of the screw hole plate 41, which in turn causes the second screw 42 to drive the conical block 43 to move up and down. When the conical block 43 moves to the position where it is in contact with the ground, the ground limits the conical block 43. During the rotation of the second screw 42, the screw hole plate 41 moves up and down, which in turn causes the screw hole plate 41 to move the frame 1 up and down, thus providing auxiliary support and reinforcement to the bottom of the frame 1.
[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
