Description

Technical Field

[0001] This utility model relates to the field of building scaffolding technology, and in particular to a guardrail scaffolding for construction projects. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes, making it convenient for workers to stand and work, and for the temporary storage of some building materials. For safety reasons, existing scaffolding will have guardrails installed at the working platform for protection.

[0003] Traditional scaffolding is installed at the construction site according to actual needs. Construction workers use ladders on the scaffolding to ascend to the working platform at the step position before carrying out their work. However, in actual use, it has been found that most existing scaffolding guardrails are welded and fixed to the scaffolding with steel pipes. This fixed height makes it difficult to accommodate workers of different heights. When taller people use the guardrails, the protective effect is weakened, and when shorter people use them, it has a certain negative impact on construction operations, reducing the effectiveness and functionality of the scaffolding. Utility Model Content

[0004] The technical problem this utility model aims to solve is that most existing scaffolding guardrails are welded and fixed between steel pipes and scaffolding. This results in a fixed protective height, which is difficult to adapt to the use of workers of different heights. When taller people use the guardrails, the protective effect is weakened, and when shorter people use them, it will have a certain negative impact on construction operations, thus reducing the effectiveness and functionality of the scaffolding.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a guardrail scaffold, including a step, with uprights fixedly connected to the four corners of the step, ladders provided on both sides of the surface of the step at the position of the uprights, and an adjustment device provided on the surface of the step, which can adjust the height of the protective components at the working position of the scaffold.

[0006] The effect achieved by the above components is as follows: when construction workers use scaffolding to carry out some construction operations during the construction process, the scaffolding is first placed at the construction position, and then the height of the workers on the platform is adjusted according to their height. Finally, the workers climb onto the platform with the help of the climbing frame on the uprights to carry out their work.

[0007] Preferably, the adjusting device includes a mounting plate with a U-shaped cross-section. Both ends of the mounting plate are slidably connected to the surface of the pedal. The surface of the mounting plate has a screw hole, and a screw is threadedly connected to the inner wall of the screw hole. The screw is rotatably connected to one side surface of the pedal. Guardrails are fixedly connected to both ends of the mounting plate. Mounting rings are fixedly connected to the four corners of the guardrails. The inner wall of the mounting ring is slidably connected to the arc surface of the upright. A stop bar is fixedly connected to the arc surface of the mounting ring.

[0008] The effect achieved by the aforementioned components is that, during construction operations using scaffolding, the protective railings can be quickly and effectively adjusted to suit the different heights of construction workers, thereby improving the safety performance of the scaffolding, better protecting the safety of construction workers, and enhancing the effectiveness and practicality of the scaffolding.

[0009] Preferably, the end of the screw away from the pedal is fixedly connected to a throttle, and the surface of the throttle is provided with several anti-slip protrusions.

[0010] The effect achieved by the above components is that the throttle makes the screw more convenient and quick to rotate, thus allowing for timely and rapid adjustments for workers of different heights, further improving the ease of use of the adjustment device.

[0011] Preferably, a nut is threaded onto the arc surface of the screw, and the nut is located between the mounting plate and the throttle.

[0012] The effect achieved by the above components is as follows: by setting the nut, after the height of the guardrail is adjusted, rotating the nut on the screw will cause the nut to contact and press against the surface of the mounting plate. At this time, during the protection process, the screw is not easy to rotate, resulting in abnormal changes in the height of the guardrail.

[0013] Preferably, a bearing is fixedly connected to one end of the screw, the inner ring of the bearing is fixedly connected to the screw, and the outer ring of the bearing is fixedly connected to the surface of the pedal.

[0014] The effect achieved by the above components is that, through the bearing arrangement, the screw is less likely to experience rotational wear with the pedal when rotating to adjust the guardrail height, thus ensuring the normal use of the screw and the pedal.

[0015] Preferably, the pedal surface is provided with connecting devices on both sides, the connecting devices include two connecting plates, two bolts are inserted through the surface of each of the two connecting plates, the two bolts are threaded to the surfaces of two adjacent pedals respectively, and the two ends of the two connecting plates abut against the surfaces of two adjacent pedals respectively.

[0016] The effect achieved by the above components is that when multiple scaffolding units are used in combination, the stability of the scaffolding can be better guaranteed, and it is less likely to sway or shake, which could cause construction workers to fall into a hole, thus further improving the safety of scaffolding use.

[0017] Preferably, reinforcing blocks are fixedly connected to both sides of the surface of the pedal, and slots are opened on the surface of the reinforcing blocks, with the connecting plate inserted into the inner wall of the slots.

[0018] The effect achieved by the above components is that the connection between the connecting plate and the tread is further improved by setting the reinforcing block, thereby better ensuring the stability of adjacent scaffolding and improving the effectiveness of the connecting device.

[0019] Preferably, washers, which are rubber rings, are fitted onto the arc surfaces of the two bolts.

[0020] The effect achieved by the above components is that, through the setting of washers, when bolts pass through the surface of the connecting plate, they can fit more stably and are less likely to have gaps, thus better fixing adjacent scaffolding through the connecting plate.

[0021] The beneficial effects of this utility model are:

[0022] This utility model allows for the rapid and effective adjustment of protective railings to accommodate the varying heights of construction workers during scaffolding operations. This enhances the safety performance of the scaffolding, better protects the safety of construction workers, and improves the effectiveness and practicality of the scaffolding.

[0029] 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.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it 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.

[0031] Figure 1 The illustrated scaffolding for construction projects includes a platform 1. Uprights 2 are fixedly connected to the four corners of the platform 1. Ladders 3 are installed on both sides of the platform 1 at the positions of the uprights 2. An adjustment device 4 is installed on the surface of the platform 1, which can adjust the height of the protective components at the working position of the scaffolding. During construction, when workers use the scaffolding for various operations, the scaffolding is first placed at the construction position. Then, the workers operate the adjustment device 4 according to their height, and finally, they climb onto the platform 1 using the ladders on the uprights 2 to work. Connecting devices 5 are installed on both sides of the surface of the platform 1.

[0032] Figure 1 , Figure 2 and Figure 3The adjustment device 4 shown includes a mounting plate 41 with a U-shaped cross-section. Both ends of the mounting plate 41 are slidably connected to the surface of the pedal 1. A screw hole 42 is provided on the surface of the mounting plate 41, and a screw rod 43 is threaded onto the inner wall of the screw hole 42. The screw rod 43 is rotatably connected to one side surface of the pedal 1. Guardrail plates 44 are fixedly connected to both ends of the mounting plate 41. Mounting rings 45 are fixedly connected to the four corners of the guardrail plates 44. The inner wall of the mounting rings 45 is slidably connected to the arc surface of the upright 2. A stop bar 46 is fixedly connected to the arc surface of the mounting rings 45. During construction, when workers use scaffolding for various operations, they first place the scaffolding at the construction location, and then proceed to work on the pedal 1 as needed. The height adjustment device 4 is operated by first rotating the screw 43 on the pedal 1. Due to the sliding limit effect between the mounting plate 41 and the pedal 1, and the sliding connection between the mounting ring 45 and the upright 2, the mounting plate 41 will slide up and down on the pedal 1 as the screw 43 rotates until the guardrail plates 44 fixedly connected to both sides of the mounting plate 41 move to the appropriate height position. Finally, the workers can use the ladder 3 on the upright 2 to move to the pedal 1 to work. At this time, when using scaffolding for construction operations, the guardrail can be quickly and effectively adjusted according to the different heights of the construction workers, which improves the safety performance of the scaffolding, better protects the safety of construction workers, and improves the use effect and practicality of the scaffolding.

[0033] Figure 1 , Figure 2 and Figure 3 The screw 43 shown is fixedly connected to a handle 47 at the end away from the pedal 1. The surface of the handle 47 is provided with several anti-slip protrusions. The handle 47 makes it easier and faster to rotate the screw 43, so that it can be adjusted quickly and timely for staff of different heights, further improving the ease of use of the adjustment device 4.

[0034] Figure 1 , Figure 2 and Figure 3 The screw 43 shown has a nut 49 threadedly connected to its arc surface, and the nut 49 is located between the mounting plate 41 and the throttle 47. By setting the nut 49, after the height of the guardrail plate 44 is adjusted, rotating the nut 49 on the screw 43 will cause the nut 49 to contact and press against the surface of the mounting plate 41. At this time, during the protection process, the screw 43 is not easy to rotate, which will cause abnormal changes in the height of the guardrail plate 44.

[0035] Figure 1 , Figure 2 and Figure 3One end of the screw 43 shown is fixedly connected to a bearing 48. The inner ring of the bearing 48 is fixedly connected to the screw 43, and the outer ring of the bearing 48 is fixedly connected to the surface of the pedal 1. By setting the bearing 48, when the screw 43 rotates to adjust the protection height of the guardrail 44, the screw 43 is less likely to experience rotational wear with the pedal 1, thereby ensuring the normal use of the screw 43 and the pedal 1.

[0036] Figure 1 and Figure 4 The connecting device 5 shown includes two connecting plates 51. Two bolts 52 are inserted through the surfaces of the two connecting plates 51 respectively. The two bolts 52 are threadedly connected to the surfaces of two adjacent footplates 1 respectively. The two ends of the two connecting plates 51 abut against the surfaces of two adjacent footplates 1 respectively. When multiple scaffolding units need to be combined to extend the working space of workers, several scaffolding units can be arranged sequentially adjacent to each other, so that the adjacent footplates 1 are in contact with each other. Then, the same connecting plate 51 is installed on both sides of the adjacent footplates 1, so that the two ends of the connecting plate 51 are in contact with the two footplates 1 at the same time. Then, the two bolts 52 are inserted through the connecting plate 51, so that the two bolts 52 are threadedly connected to the two adjacent footplates 1 respectively. When multiple scaffolding units are used in combination, the stability of the scaffolding can be better guaranteed, and it is not easy for swaying and shaking to occur, which could cause construction workers to fall into the air, thus further improving the safety of scaffolding use.

[0037] Figure 1 and Figure 4 Reinforcing blocks 53 are fixedly connected to both sides of the surface of the step 1 shown. The surface of the reinforcing block 53 has a slot 54. The connecting plate 51 is inserted into the inner wall of the slot 54. The reinforcement blocks 53 further improve the connection between the connecting plate 51 and the step 1, thereby better ensuring the stability of the adjacent scaffolding and improving the performance of the connecting device 5. Washers 55 are respectively fitted on the arc surface of the two bolts 52. The washers 55 are rubber rings. The washers 55 make the bolts 52 fit more stably and securely when they pass through the surface of the connecting plate 51, and prevent gaps from forming. This allows for better fixation of the adjacent scaffolding through the connecting plate 51.

[0038] Working Principle: During construction, when workers use scaffolding for various operations, the scaffolding is first placed at the construction site. Then, based on the height of the workers on the platform 1, the adjustment device 4 is operated. First, the handle 47 fixedly connected to the screw 43 is rotated, causing the screw 43 on the platform 1 to rotate. Due to the sliding limit effect between the mounting plate 41 and the platform 1, and the sliding connection between the mounting ring 45 and the upright 2, the mounting plate 41 will slide up and down on the platform 1 as the screw 43 rotates, until the guardrail plates 44 fixedly connected to both sides of the mounting plate 41 move to the appropriate height position. Then, the nut 49 on the arc surface of the screw 43 is rotated until the nut 49 contacts and presses against the mounting plate 41. Finally, the workers use the ladder 3 on the upright 2 to move to the platform 1 to work. In this way, when using scaffolding for construction operations, the guardrail can be quickly and effectively adjusted according to the different heights of the workers, improving the safety performance of the scaffolding, better protecting the safety of the workers, and enhancing the effectiveness and practicality of the scaffolding.

[0039] When multiple scaffolding units need to be combined to extend the working space for workers, several scaffolding units can be arranged adjacent to each other so that adjacent footboards 1 are in contact with each other. Then, the same connecting plate 51 is installed on both sides of the adjacent footboards 1, so that the two ends of the connecting plate 51 are in contact with the inner wall of the slot 54 of the mounting block on the two footboards 1. Then, two bolts 52 are passed through the connecting plate 51 and threadedly connected to the two adjacent footboards 1 respectively. When multiple scaffolding units are used in combination, the stability of the scaffolding can be better guaranteed, and it is less likely to sway or shake, causing construction workers to fall into the air, thus further improving the safety of scaffolding use.

[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.
