Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a construction work platform. Background Technology

[0002] Building construction, as the core production activity in the implementation phase of engineering construction, is a meticulous process of transforming the creative blueprints of designers into physical buildings. It encompasses multiple key aspects such as foundation construction, main structure construction, roof construction, and decoration construction. Moreover, each step involves extremely high requirements for precision and safety. In modern building construction, with the continuous increase in building height and the increasing complexity of building structures, efficient and safe high-altitude operations have become the key to ensuring project progress and quality.

[0003] When performing high-altitude operations at construction sites, supported work platforms are required. However, traditional work platforms typically consist of multiple fixed components such as uprights, crossbars, and scissor braces. On-site erection is slow, requiring construction workers to expend a significant amount of time and effort. Fastening these components with bolts and other fasteners is not only labor-intensive but also inefficient. Furthermore, since the height of these fixed components remains constant, the height of the work platform must be readjusted when work needs to be performed at different heights, which is inconvenient, cumbersome, and time-consuming, severely impacting the construction progress. In addition, when traditional work platforms are erected at greater heights, their lateral overturning resistance weakens with increasing height due to their vertical frame structure, resulting in lower safety. Utility Model Content

[0004] The purpose of this utility model is to provide a construction work platform to solve the problems of low installation efficiency, cumbersome height adjustment, poor convenience, poor anti-overturning ability, and low safety of traditional construction work platforms in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A construction work platform, comprising:

[0007] A platform plate and at least two lifting structures, each of which is supported below the platform plate and is configured to lift the platform plate to adjust its height.

[0008] Each of the lifting structures is connected to a rotating structure, and each of the rotating structures is mounted on the platform plate. Each of the lifting structures is configured to rotate around its corresponding rotating structure to adjust the angle, so that each of the lifting structures can provide oblique support.

[0009] A locking structure is provided, which is connected to each of the lifting structures, and is used to lock the oblique angle of each of the lifting structures.

[0010] Based on the aforementioned technical means, the platform slab, serving as a platform for construction workers to operate at height, is supported on the ground by a lifting structure. Under the support and lifting action of the lifting structure, stable support and flexible adjustment of the working height of the platform slab are achieved. The structure is simple, easy to install and adjust, and highly convenient. Furthermore, the rotating structure allows for the rotation of the lifting structure to adjust its tilt angle. After the working height of the platform slab is adjusted, the lifting structure provides oblique support, and the tilt directions of each lifting structure are centrally symmetrical. This interaction of the oblique supports of each lifting structure enhances the platform slab's anti-overturning ability, improves its adaptability and stability, and ensures construction safety, enabling it to maintain a stable working state under various complex terrains and construction conditions. In addition, after the tilt angle of the lifting structure is adjusted to the required angle, a locking structure connects to each lifting structure, ensuring the lifting structure remains stable and preventing rotational loosening during construction operations that could cause angle changes. This avoids risks such as platform swaying and collapse, further increasing the stability and safety of the platform slab during operation.

[0011] Furthermore, the lifting structure includes a first support column and a second support column. The first support column and the second support column are parallel and slidably connected. The first support column is configured to slide along its length on the second support column. One end of the first support column is connected to the platform plate through a corresponding rotating structure, and the other end is connected to a limiting structure. The limiting structure is configured to connect with the second support column to fix the first support column on the second support column. The second support column is connected to a locking structure.

[0012] Based on the aforementioned technical means, the first and second support columns are slidably connected, allowing the first support column to slide freely along the length of the second support column. This enables height adjustment of the platform panel, providing high flexibility and smooth, stable adjustment. After the platform panel is adjusted to the desired position, the first and second support columns are locked by a limiting structure. This not only ensures the stability of the support provided by the first and second support columns but also facilitates precise height adjustment by construction personnel. Furthermore, the rotation structure allows for angle adjustment of the first and second support columns, enabling oblique support and improving overturning resistance. The locking structure locks the tilt angle of the first and second support columns, ensuring the stability and safety of the platform panel and preventing risks such as platform panel swaying or collapse caused by external forces. This enhances the safety performance and operational efficiency of the work platform.

[0013] Furthermore, the first support column is a first ladder frame, which includes two parallel first columns, and a plurality of first crossbars are spaced apart between the two first columns along their length direction, and the first crossbars are perpendicular to the first columns.

[0014] The second support column is a second ladder frame, which includes two parallel second columns. Multiple second crossbars are spaced apart between the two second columns along their length. The second crossbars are perpendicular to the second columns, and one of the second crossbars is connected to a locking structure.

[0015] The two first columns are parallel to the two second columns, and the two first columns are slidably connected to the corresponding second columns. One end of the two first columns is connected to the platform plate through a corresponding rotating structure, and the other end is connected to a limiting structure. The limiting structure can be connected to the two second columns.

[0016] Based on the aforementioned technical means, by using the first ladder frame as the first support column and the second ladder frame as the second support column, the first and second ladder frames are slidably connected to form a lifting ladder. This not only provides stable support for the platform panel but also allows for height adjustment to meet the needs of the platform panel at different heights. Furthermore, the lifting ladder can also serve as a ladder for climbing the platform panel, facilitating the ascent and descent of construction workers during high-altitude operations. It is convenient to use and highly practical. Specifically, the two first columns are slidably connected to their corresponding second columns, simplifying the adjustment process of the lifting ladder and ensuring the stability of the platform panel during lifting. The rotating structure enables angle adjustment of the lifting ladder, allowing it to achieve oblique support to improve its anti-overturning ability. The locking structure locks the tilt angle of the lifting ladder, ensuring the stability and safety of the platform panel and preventing risks such as platform panel swaying or collapse caused by external forces, thereby improving the safety performance and operational efficiency of the work platform.

[0017] Furthermore, a locking strip is fixed on the first column along its length, and a locking groove is formed on the second column along its length, with the locking strip slidably locked in the locking groove.

[0018] According to the above-mentioned technical means, the first column can slide smoothly and accurately along the length direction of the second column through the locking strip and the locking groove. At the same time, the close cooperation between the locking strip and the locking groove ensures the stability and guidance of the sliding process, and ensures the stability and safety of the platform plate during the lifting process.

[0019] Furthermore, the rotating structure includes a mounting frame, a rotating shaft, and two sleeves. The mounting frame is fixed to one end of the two first columns. The rotating shaft is rotatably mounted on the mounting frame and parallel to the first crossbar. The two sleeves are fixed to the platform plate and coaxially sleeved at both ends of the rotating shaft. The two first columns are configured to rotate around the central axis of the rotating shaft for angle adjustment.

[0020] Based on the above technical means, the rotating shaft is rotatably installed between the first column and the platform plate through the mounting bracket and two sleeves. The structure is simple and easy to install. The rotating shaft is parallel to the first crossbar, which allows the first column to be flexibly adjusted around the central axis of the rotating shaft. This ensures the stability and safety of the entire platform plate during the angle adjustment process. In actual use, construction personnel can easily adjust the tilt angle of the platform plate to adapt to different construction environments and needs.

[0021] Furthermore, the limiting structure includes an annular hoop, which is sleeved on the two corresponding second columns and fixed to the ends of the two first columns away from the rotating structure. Multiple limiting holes are formed on the two second columns, and each limiting hole is evenly distributed along the length of the second column. Two symmetrically arranged limiting bolts are threaded onto the annular hoop. One end of each of the two limiting bolts can be inserted into one of the limiting holes on the adjacent second column, and the other end is fixed with a handle.

[0022] According to the above-mentioned technical means, the two first columns are connected by a ring hoop and fitted onto the corresponding two second columns. This not only improves the firmness and stability of the connection between the two first columns, but also does not hinder the sliding of the two first columns on the corresponding second columns. Specifically, when the elevator is adjusted to the required height, the handle is rotated to adjust the limit bolt, so that it is inserted into the corresponding limit hole on the second column, thereby locking the first ladder frame on the second ladder frame to achieve stable support, convenient adjustment and good stability.

[0023] Furthermore, the locking structure includes a pull rope and a tightening wheel. One end of the pull rope is connected to the tightening wheel, and the other end is provided with the same number of connectors as the lifting structure. Each connector is connected to one of the second crossbars of the corresponding second ladder. The tightening wheel is configured to tighten the pull rope to make each connector taut or release the pull rope.

[0024] Based on the aforementioned technical means, tightening the pull rope via the tightening wheel enables a simple and quick locking of the tilt angle of the lifting structure. Specifically, when it is necessary to lock the tilt angle of the lifting structure, simply tighten the pull rope to taut all the connectors. The tension of the pull rope will then securely fix the lifting structure at the current angle, preventing it from rotating or loosening during use. When it is necessary to adjust the angle of the lifting structure, simply release the pull rope to easily adjust the angle. This method is highly efficient and ensures construction safety.

[0025] Furthermore, each of the second columns has an anti-slip pad fixed at its bottom end along its circumference, and the anti-slip pad has a tapered slope.

[0026] Based on the aforementioned technical means, by fixing an anti-slip pad to the bottom of the second column, the friction between the second column and the ground is increased. Even on wet or uneven ground, the working platform can be ensured to be stable and not slip. Furthermore, the conical slope design ensures the contact area between the second column and the ground when it is supported at an angle, further enhancing the anti-slip effect. This not only improves the overturning resistance of the platform but also makes it easier for construction personnel to move and adjust the position of the second column when installing and dismantling the working platform, thereby improving construction efficiency.

[0027] Furthermore, each of the second columns is equipped with casters at its bottom.

[0028] Based on the above-mentioned technical means, by installing casters at the bottom of the second column, the work platform can be moved easily, resulting in high construction efficiency and saving manpower.

[0029] Furthermore, it also includes four guardrails, which are evenly distributed around the circumference of the platform. Each of the four guardrails is fixed with a first telescopic rod. The end of each first telescopic rod away from the guardrail is fixed to the platform and configured to drive the corresponding guardrail to move up and down in the vertical direction. Each of the four guardrails is fixed with a second telescopic rod at both ends. The end of each second telescopic rod away from the guardrail is fixed with a locking block and configured to drive the corresponding locking block to extend and retract along the length of the guardrail. Each locking block has a concave locking slot, and the concave locking slots on two adjacent locking blocks can engage with each other.

[0030] According to the aforementioned technical means, the four guardrails can be connected end-to-end through the locking blocks at both ends to form a closed protective frame, ensuring the safety of construction personnel. The concave locking openings at the ends of two opposite guardrails face upwards, while the concave locking openings at the ends of the other two opposite guardrails face downwards, ensuring that the concave locking openings on adjacent blocks can interlock. Specifically, in use, the four guardrails are raised to the required height via their respective first telescopic rods. Then, the second telescopic rods at both ends of the four guardrails extend the corresponding locking blocks, allowing the concave locking openings on adjacent blocks to interlock, completing the installation of the protective frame and ensuring the safety of construction personnel. After construction is completed, the adjacent locking blocks are released, the second telescopic rods retract the corresponding locking blocks, and the four guardrails descend to their original positions via their respective first telescopic rods, facilitating the access of construction personnel to and from the platform.

[0031] The beneficial effects achieved by this utility model are:

[0032] 1. In this utility model, the platform board serves as a platform for construction workers to work at height. It is supported on the ground by a lifting structure. Under the support and lifting action of the lifting structure, the platform board is stably supported and the working height is flexibly adjusted. The structure is simple, easy to install and adjust, and highly convenient. Furthermore, the lifting structure can be rotated through a rotating structure to adjust its tilt angle. After the working height of the platform board is adjusted, the lifting structure provides oblique support. Moreover, the tilt directions of each lifting structure are centrally symmetrical. Thus, the interaction of the oblique supports of each lifting structure enhances the platform board's anti-overturning ability, improves its adaptability and stability, ensures construction safety, and enables it to maintain a stable working state under various complex terrains and construction conditions.

[0033] 2. After the tilt angle of the lifting structure is adjusted to the required angle, the present invention connects to each lifting structure through a locking structure, so that the lifting structure can remain stable and prevent the lifting structure from rotating and loosening during construction operations, thereby avoiding the risk of platform board shaking or collapsing, and further increasing the stability and safety of platform board operation.

[0049] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0050] This embodiment relates to a construction work platform, such as... Figure 1 As shown, it includes: a platform plate 1 and at least two lifting structures 2, each lifting structure 2 being supported below the platform plate 1, each lifting structure 2 being configured to drive the platform plate 1 to rise and fall, thereby adjusting the height of the platform plate 1; each lifting structure 2 being connected to a rotating structure 3, each rotating structure 3 being mounted on the platform plate 1, each lifting structure 2 being configured to rotate around its corresponding rotating structure 3, thereby adjusting the angle so that each lifting structure 2 can be supported at an angle; and a locking structure 4, which is connected to each lifting structure 2 and is used to lock the angle of each lifting structure 2.

[0051] In this embodiment, platform 1 serves as a platform for construction workers to work at height. Supported on the ground by lifting structure 2, the platform 1 achieves stable support and flexible adjustment of its working height through the support and lifting action of lifting structure 2. The structure is simple, easy to install and adjust, and highly convenient. Furthermore, by rotating structure 3, lifting structure 2 can be rotated to adjust its tilt angle. After the working height of platform 1 is adjusted, lifting structure 2 provides oblique support. The tilt directions of each lifting structure 2 are centrally symmetrical, thus enhancing the anti-overturning ability of platform 1 through the interaction of the oblique supports of each lifting structure 2. This improves the adaptability and stability of platform 1, ensuring construction safety and enabling it to maintain a stable working state under various complex terrains and construction conditions. In addition, after the tilt angle of lifting structure 2 is adjusted to the required angle, locking structure 4 connects to each lifting structure 2, ensuring that lifting structure 2 remains stable and preventing it from rotating and loosening during construction, thus avoiding risks such as shaking or collapse of platform 1 and further increasing the stability and safety of platform 1 during operation.

[0052] In this embodiment, the lifting structure 2 includes a first support column 21 and a second support column 22. The first support column 21 and the second support column 22 are parallel and slidably connected. The first support column 21 is configured to slide along its length on the second support column 22. One end of the first support column 21 is connected to the platform plate 1 through a corresponding rotating structure 3, and the other end is connected to a limiting structure 5. The limiting structure 5 is configured to connect with the second support column 22 to fix the first support column 21 on the second support column 22. The second support column 22 is connected to a locking structure 4.

[0053] like Figure 1As shown, this embodiment achieves height adjustment of the platform plate 1 through the sliding connection of the first support column 21 and the second support column 22. This provides high flexibility and smooth, stable adjustment. Specifically, in practical applications, according to the needs of high-altitude operations, the first support column 21 is slid along the length of the second support column 22 to adjust the platform plate 1 to the required position. Then, the limiting structure 5 limits and locks the first support column 21 and the second support column 22, preventing the first support column 21 from sliding on the second support column 22. This not only ensures the stability of the support provided by the first support column 21 and the second support column 22 but also facilitates precise height adjustment by construction personnel. Furthermore, the rotation structure 3 enables angle adjustment of the first support column 21 and the second support column 22, allowing them to achieve oblique support to improve overturning resistance. The locking structure 4 locks the tilt angle of the first support column 21 and the second support column 22, ensuring the stability and safety of the platform plate 1 and preventing risks such as shaking or collapse of the platform plate 1 due to external forces. This improves the safety performance and operational efficiency of the work platform.

[0054] In this embodiment, the first support column 21 is a first ladder frame, which includes two parallel first columns 211. Multiple first crossbars 212 are spaced apart along the length of the two first columns 211, and the first crossbars 212 are perpendicular to the first columns 211. The second support column 22 is a second ladder frame, which includes two parallel second columns 221. Multiple second crossbars 222 are spaced apart along the length of the two second columns 221, and the second crossbars 222 are perpendicular to the second columns 221. One of the second crossbars 222 is connected to the locking structure 4. The two first columns 211 are parallel to the two second columns 221, and the two first columns 211 are slidably connected to their corresponding second columns 221. One end of each of the two first columns 211 is connected to the platform plate 1 via a corresponding rotating structure 3, and the other end is connected to a limiting structure 5. The limiting structure 5 can be connected to the two second columns 221.

[0055] like Figure 2As shown, this embodiment uses a first ladder frame as a first support column 21 and a second ladder frame as a second support column 22, with the first and second ladder frames slidably connected to form a lifting ladder. This not only stably supports the platform slab but also allows for height adjustment to meet the needs of the platform slab at different heights. Furthermore, the lifting ladder can also serve as a ladder for climbing the platform slab, facilitating workers' ascent and descent during high-altitude operations. It is convenient to use and highly practical. Specifically, in practical applications, according to the needs of high-altitude operations, the first ladder frame is slid along the length of the second ladder frame to adjust the platform slab to the required position, and then... Positioning structure 5 limits and locks the first and second ladder frames, preventing the first ladder frame from sliding on the second ladder frame. This not only ensures the stability of the elevator support but also facilitates precise height adjustment by construction personnel. Furthermore, the rotating structure 3 enables angle adjustment of the elevator, allowing it to achieve oblique support and improve its anti-overturning ability. The locking structure 4 locks the tilt angle of the elevator, ensuring the stability and safety of the platform 1 and preventing risks such as shaking or collapse of the platform 1 due to external forces. This improves the safety performance and work efficiency of the work platform.

[0056] Furthermore, in a preferred embodiment, a retaining strip 2111 is fixed on the first column 211 along its length, and a retaining groove 2211 is formed on the second column 221 along its length, with the retaining strip 2111 slidably engaged within the retaining groove 2211; as shown Figure 3 As shown, by engaging the locking strip 2111 with the locking groove 2211, the first column 211 can slide smoothly and precisely along the length direction of the second column 221. At the same time, the tight cooperation between the locking strip 2111 and the locking groove 2211 ensures the stability and guidance of the sliding process, and ensures the stability and safety of the platform plate 1 during the lifting process.

[0057] In this embodiment, the rotating structure 3 includes a mounting frame 31, a rotating shaft 32, and two sleeves 33. The mounting frame 31 is fixed to one end of the two first columns 211. The rotating shaft 32 is rotatably mounted on the mounting frame 31 and parallel to the first crossbar 212. The two sleeves 33 are fixed on the platform plate 1 and are coaxially sleeved on both ends of the rotating shaft 32. The two first columns 211 are configured to rotate around the central axis of the rotating shaft 32 for angle adjustment.

[0058] like Figure 2 and Figure 3As shown, in this embodiment, the rotating shaft 32 is rotatably installed between the first column 211 and the platform plate 1 via the mounting bracket 31 and two sleeves 33. The structure is simple and easy to install. Specifically, in actual application, the rotating shaft 32 is kept parallel to the first crossbar 212. Construction personnel can easily rotate the first column 211 around the central axis of the rotating shaft 32 to adjust to the required tilt angle, so that the elevator can be supported at an angle, ensuring the stability and safety of the entire platform plate 1 during the angle adjustment process.

[0059] In this embodiment, the limiting structure 5 includes an annular hoop 51, which is sleeved on the corresponding two second columns 221 and fixed to the ends of the two first columns 211 away from the rotating structure 3. Multiple limiting holes 52 are formed on the two second columns 221, and each limiting hole 52 is evenly distributed along the length direction of the second column 221. Two symmetrically arranged limiting bolts 53 are threaded onto the annular hoop 51. One end of each of the two limiting bolts 53 can be inserted into one of the limiting holes 52 on the adjacent second column 221, and the other end is fixed with a handle.

[0060] like Figure 2 and Figure 4 As shown, in practical application, the two first columns 211 are connected by the ring hoop 51 and fitted onto the corresponding two second columns 221. Specifically, when the elevator is adjusted to the required height, the construction worker rotates the handle to adjust the limiting bolt 53 so that it is inserted into the corresponding limiting hole 52 on the second column 221, thereby locking the first ladder frame onto the second ladder frame to achieve stable support, convenient adjustment and good stability.

[0061] In this embodiment, the locking structure 4 includes a pull rope 41 and a tightening wheel 42. One end of the pull rope 41 is connected to the tightening wheel 42, and the other end is provided with the same number of connectors as the lifting structure 2. Each connector is connected to one of the second crossbars 222 of the corresponding second ladder. The tightening wheel 42 is configured to tighten the pull rope 41 so that each connector is taut, or to release the pull rope 41.

[0062] like Figure 1 As shown, in practical application, after the lifting structure 2 is adjusted to the required angle, the construction personnel connect the connector of the pull rope 41 to a second crossbar 222 in each lifting structure. Then, they only need to tighten the pull rope 41 to make each connector taut. Thus, the lifting structure 2 with inclined support improves its anti-overturning ability under the action of mutual force. The lifting structure 2 is firmly fixed at the current angle to prevent it from rotating or loosening during use. When it is necessary to adjust the angle of the lifting structure 2, the pull rope can be released to easily adjust the angle. The adjustment efficiency is high and the construction safety is guaranteed.

[0063] In this embodiment, each of the second columns 221 has an anti-slip pad 6 fixed to its circumference at its bottom end, and the anti-slip pad 6 has a conical inclined surface formed on it; such as Figure 5 and Figure 6 As shown, this embodiment increases the friction between the second column 221 and the ground by fixing an anti-slip pad 6 to the bottom of the second column 221. Even on wet or uneven ground, it ensures that the working platform is stable and does not slip. The conical slope design ensures the contact area between the second column 221 and the ground when it is supported at an angle, further enhancing the anti-slip effect. This not only improves the overturning resistance of the platform plate 1, but also makes it easier for construction personnel to move and adjust the position of the second column when installing and dismantling the working platform, thereby improving construction efficiency.

[0064] In this embodiment, each of the second columns 221 is equipped with a caster wheel 7 at its bottom; such as Figure 5 As shown, in this embodiment, universal wheels 7 are installed at the bottom of the second column 221, which facilitates the movement of the work platform, resulting in high construction efficiency and saving manpower.

[0065] In this embodiment, four guardrails 81 are also included. The four guardrails 81 are evenly distributed around the circumference of the platform plate 1. A first telescopic rod 82 is fixed to each of the four guardrails 81. The end of each first telescopic rod 82 away from the guardrail 81 is fixed to the platform plate 1 and is configured to drive the corresponding guardrail 81 to move up and down in the vertical direction. A second telescopic rod 83 is fixed to both ends of each of the four guardrails 81. A locking block 84 is fixed to the end of each second telescopic rod 83 away from the guardrail 81 and is configured to drive the corresponding locking block 84 to extend and retract along the length of the guardrail 81. A concave locking slot 841 is formed on each locking block 84, and the concave locking slots 841 on two adjacent locking blocks 84 can engage with each other.

[0066] like Figure 7 As shown, in practical application, the four guardrails 81 are raised to the required height via the corresponding first telescopic rods 82. Then, the second telescopic rods 83 at both ends of the four guardrails 81 drive the corresponding locking blocks 84 to extend, so that the concave locking slots 841 on the two adjacent locking blocks 84 engage with each other, completing the installation of the protective frame and ensuring the safety of construction workers. After the construction is completed, the two adjacent locking blocks are released, the second telescopic rods drive the corresponding locking blocks 84 to retract, and the four guardrails 81 are lowered to their original positions via the corresponding first telescopic rods 82, making it convenient for construction workers to go up and down the platform 1.

[0067] Working principle: During use, the work platform is moved to the required construction site by the casters 7. According to the construction height requirements, the first ladder frame is slid to drive the platform plate 1 to rise and fall. After the platform plate 1 is adjusted to the required height, the construction personnel rotate the handle to adjust the limit bolt 53 so that it is inserted into the corresponding limit hole 52 on the second column 221, thereby locking the first ladder frame on the second ladder frame. At the same time, the first column 211 is rotated around the central axis of the rotating shaft 32 to adjust the lifting ladder to the required inclined support angle. Then, the connector of the pull rope 41 is connected to a second crossbar 222 in each lifting structure. The pull rope 41 is tightened to fix the lifting ladder so that it will not expand outward and ensure stability. Finally, the two ends of the four guardrails 81 are fastened to each other to form a closed protective frame, and then the construction work begins.
