Description

Technical Field

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

[0002] In the field of building construction, the application of long-span suspension bridges is becoming increasingly widespread, and their jacking construction technology is becoming more and more common. In the early stage of steel beam jacking construction, it is necessary to bolt together the individual steel beam components.

[0003] However, for various high-altitude operations such as bolt connections, aerial work platforms are currently commonly used as construction platforms. Because the position of the aerial work platform needs to be frequently changed when working on different areas of the steel beam, workers must dismount from the platform after completing work in one area, move the platform to the next area to be worked on, and then climb back onto the platform to continue the work. This process not only consumes a significant amount of time and manpower, causing considerable inconvenience to construction workers, but also reduces construction efficiency and increases the overall project duration and cost. Utility Model Content

[0004] The purpose of this utility model is to provide an operating platform to solve the technical problems of low efficiency and high cost in providing workers with construction areas through aerial work platforms during high-altitude operations in the prior art.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] An operating platform, comprising:

[0007] Cantilever beam

[0008] Multiple operating units are connected to the cantilever beam, and the multiple operating units are arranged at intervals along the length direction of the cantilever beam. The cantilever beam between each two adjacent operating units can overlap the top of the truss chord.

[0009] The operating unit includes a support frame and a support base plate. The support base plate is fixed to the support frame, and the top surface of the support base plate forms an operating plane. The support frame is connected between the support base plate and the cantilever beam.

[0010] Preferably, the outer periphery of the support base plate is provided with a blocking side plate, which is vertical and protrudes from the operating plane.

[0011] Preferably, two cantilever beams are provided, and the two cantilever beams are symmetrically arranged on both sides of the operating unit.

[0012] Preferably, the cantilever beam is a channel steel, which is welded to the outer wall of the support frame.

[0013] Preferably, there are two operating units, which are suspended at both ends of the cantilever beam.

[0014] Preferably, the support frame includes vertical beams and horizontal beams. The four vertical beams are welded to the four corners of the support base plate, and a horizontal beam is provided between two adjacent vertical beams. The vertical beams and the horizontal beams together form an accommodating space on the operating plane.

[0015] Preferably, a ladder is provided on the inner wall of the accommodating space, the ladder being used to connect the operating plane with the top of the truss chord.

[0016] Preferably, at least three crossbeams are arranged at intervals along the height direction between each pair of adjacent vertical beams.

[0017] Preferably, a plurality of reinforcing beams are welded onto the supporting base plate, and the plurality of reinforcing beams are arranged at intervals along the length direction of the supporting base plate.

[0018] Preferably, the support base plate has multiple through holes extending along its own height direction.

[0019] The beneficial effects of this utility model are:

[0020] The operating platform proposed in this utility model is used by hoisting the assembled platform above the section of the steel truss to be constructed before construction. The position is adjusted so that the middle section of the cantilever beam accurately overlaps the top of the truss chord. At this point, multiple operating units automatically suspend on both sides of the truss chord. After climbing onto any operating unit, the operator can perform operations on that side on the operating plane formed by the supporting base plate. When it is necessary to move to an adjacent operating unit, the operator directly climbs from the current supporting base plate to the top of the truss chord, moves laterally along the truss chord to the target operating unit, and then enters its supporting base plate to continue working. Throughout the entire construction process, the operator does not need to return to the ground or use external lifting equipment. Continuous operation between multiple operating units can be achieved only within the length of the truss chord covered by the cantilever beam, through the passage at the top of the truss chord, until the operation of that section is completed.

[0021] By directly connecting the cantilever beams to the top of the truss chords between adjacent operating units, multiple operating units are stably suspended on both sides of the truss chords. Operators no longer need to repeatedly climb or rely on mobile climbing equipment; they can complete their work on the current construction section from the operating plane of their unit and transfer between adjacent operating units using the top of the truss chords. This integrated structure not only eliminates the time wasted on frequent climbing up and down of the operating platform but also ensures the continuity of the construction process, allowing operators to perform operations smoothly within the covered truss chord length. Simultaneously, the rigid operating plane formed by the support frame and support base plate provides operators with a stable and reliable work position, reducing the risks of working at height. The overall structure simplifies the construction process, shortens the time spent on operating procedures, and provides efficient and safe working conditions for steel truss erection projects.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] See Figures 1 to 3 The operating platform provided in this embodiment of the utility model includes a cantilever beam 1 and multiple operating units 2. The multiple operating units 2 are connected to the cantilever beam 1 and are spaced apart along the length of the cantilever beam 1. The cantilever beam 1 between each pair of adjacent operating units 2 can overlap the top of the truss chord. Each operating unit 2 includes a support frame 21 and a support base plate 22. The support base plate 22 is fixed to the support frame 21, and the top surface of the support base plate 22 forms an operating plane. The support frame 21 is connected between the support base plate 22 and the cantilever beam 1.

[0033] The operating platform proposed in this utility model is used by hoisting the assembled platform above the section of the steel truss to be constructed before construction. The position is adjusted so that the middle section of the cantilever beam 1 accurately overlaps the top of the truss chord. At this time, multiple operating units 2 automatically suspend on both sides of the truss chord. After climbing onto any operating unit 2, the operator can perform operations on that side on the operating plane formed by the supporting base plate 22. When it is necessary to move to an adjacent operating unit 2, the operator directly climbs from the current supporting base plate 22 to the top of the truss chord, moves laterally along the truss chord to the target operating unit 2, and then enters its supporting base plate 22 to continue working. Throughout the entire construction process, the operator does not need to return to the ground or use external lifting equipment. Continuous operation between multiple operating units 2 can be achieved only within the length of the truss chord covered by the cantilever beam 1, through the passage at the top of the truss chord, until the operation of that section is completed.

[0034] By directly connecting the cantilever beam 1 to the top of the truss chord between adjacent operating units 2, multiple operating units 2 are stably suspended on both sides of the truss chord. Operators do not need to repeatedly climb or rely on mobile climbing equipment; they can complete the work for the current construction section from the operating plane of the operating unit 2 and transfer between adjacent operating units 2 using the top of the truss chord. This integrated structure not only eliminates the time wasted on frequent climbing up and down of the operating platform but also ensures the continuity of the construction process, allowing operators to perform operations smoothly within the covered truss chord length. Simultaneously, the rigid operating plane formed by the support frame 21 and the support base plate 22 provides operators with a stable and reliable work position, reducing the risks of working at height. The overall structure simplifies the construction process, shortens the time spent on operating procedures, and provides efficient and safe working conditions for steel truss erection projects.

[0035] The specific structure and working principle of this operating platform will be described in detail below.

[0036] Specifically, two cantilever beams 1 are provided, symmetrically arranged on both sides of the operating unit 2. By symmetrically setting up double cantilever beams 1 on both sides of the operating unit 2, a balanced load-bearing support system is formed, effectively distributing the construction load and the dynamic load generated by the movement of operators. The structure of double cantilever beams 1 improves the torsional and lateral deformation resistance of the operating unit 2, maintaining the horizontal stability of the operating plane even when operating on one side, avoiding the risk of platform overturning due to uneven stress. At the same time, the symmetrical layout makes it easier to level and align during the hoisting and erection process, reducing the impact of installation deviations on structural safety.

[0037] More specifically, the cantilever beam 1 is a channel steel, welded to the outer wall of the support frame 21. Using channel steel as the cantilever beam 1 fully utilizes its cross-sectional properties to provide stronger bending resistance under the same weight, ensuring effective resistance to deformation caused by construction loads when lapped at the top of the truss chord. Welding the channel steel directly to the outer wall of the support frame 21 to form a rigid node not only eliminates the potential loosening of bolted connections but also enables full-section force transfer between the cantilever beam 1 and the support frame 21, avoiding localized stress concentration. Furthermore, channel steel, as a standard profile, is easy to procure and process, and the outer wall welding process is simple and reliable, balancing structural performance and construction economy.

[0038] In this embodiment, two operating units 2 are provided, suspended at both ends of the cantilever beam 1. The design of placing the two operating units 2 at opposite ends of the cantilever beam 1 allows them to cover both working surfaces of the steel truss chord while forming a natural counterweight system centered on the lap joint of the cantilever beam 1. After completing bolting work on one side of the truss chord, operators can directly transfer to the other operating unit 2 via the top of the truss chord to continue construction. The symmetrical suspension structure ensures that the construction load is evenly distributed to the lap joint of the cantilever beam 1, avoiding the risk of instability caused by eccentric loading. Compared to complex multi-unit structures, the dual operating unit 2 scheme achieves full functional coverage with the simplest components, reducing manufacturing costs and hoisting difficulty, and offering higher safety and economy.

[0039] In other alternative embodiments, the number of operating units 2 can be flexibly set according to actual construction needs, such as three, four, or other numbers. However, it is worth noting that the specific arrangement must ensure that the spacing of the operating units 2 along the cantilever beam 1 matches the distribution position of the truss chords, so that the cantilever beam 1 section between each two adjacent operating units 2 can reliably overlap the top of the truss chords. This ensures that the operating platform meets the construction coverage requirements of truss chords of different spans while guaranteeing stable support for each operating unit 2 section, thereby achieving both structural safety and functional adaptability of the operating platform.

[0040] The operating unit 2 includes a support frame 21 and a support base plate 22. The support base plate 22 is fixed on the support frame 21, and the top surface of the support base plate 22 forms an operating plane. The support frame 21 is connected between the support base plate 22 and the cantilever beam 1.

[0041] Specifically, the support frame 21 includes vertical beams 211 and horizontal beams 212. Four vertical beams 211 are welded to the four corners of the support base plate 22, and a horizontal beam 212 is positioned between adjacent vertical beams 211. The vertical beams 211 and horizontal beams 212 together enclose an accommodating space 210 on the operating plane. This structural design enhances the overall stability of the operating platform. The vertical beams 211 are welded to the four corners of the support base plate 22, providing vertical support for the operating unit 2. The horizontal beams 212 connect to the vertical beams 211, effectively resisting horizontal forces, ensuring the stability of the operating unit 2 under different stress conditions and guaranteeing the safety of the operator when working on the operating plane. The accommodating space 210 formed by the vertical beams 211 and the horizontal beams 212 is practical. The accommodating space 210, together with the operating plane at the bottom, facilitates the placement of operators and parts, tools, etc. for operation. The vertical beams 211 and the horizontal beams 212 around the accommodating space 210 provide fall protection, provide physical boundary protection for operators, and create a safe and stable working environment for high-altitude operations.

[0042] Preferably, at least three crossbeams 212 are arranged at intervals along the height direction between every two adjacent vertical beams 211. The multiple crossbeams 212 are evenly distributed along the height direction, which can more effectively disperse various forces from the operating plane, including the weight of construction personnel, the weight of tools and equipment, and the impact force generated during construction. This makes the pressure borne by the vertical beams 211 more uniform, reduces local stress concentration, and lowers the risk of deformation or damage to the support frame 21. As a result, it provides more reliable support for the operating platform, ensures the safety of construction personnel working at height, and enhances the overall strength and stability of the support frame 21.

[0043] Preferably, a ladder is provided on the inner wall of the accommodating space 210 to connect the operating plane and the top of the truss chord. The ladder provides operators with a convenient and safe access. It allows operators to move between the operating plane and the top of the truss chord without the need for other complex or unstable climbing equipment, reducing the safety risks associated with frequent changes in climbing methods and improving safety during construction. Furthermore, the ladder enhances the connection between the operating platform and the top of the truss chord, making platform changes smoother for workers, saving construction time and improving work efficiency.

[0044] The supporting base plate 22 is used to support operators and related parts, tools, etc. Specifically, a blocking side plate 221 is provided on the outer periphery of the supporting base plate 22. The blocking side plate 221 is vertical and protrudes from the working surface. The blocking side plate 221 can effectively prevent tools, parts, and other items from slipping off the edge of the working surface during construction, avoiding damage or safety accidents caused by falling items, and ensuring the safety and order of the construction site. At the same time, the blocking side plate 221 can also serve as a certain degree of enclosure, enhancing the safety of operators when working at the edge of the working surface.

[0045] Preferably, multiple reinforcing beams 222 are welded onto the supporting base plate 22, and these beams are spaced apart along the length of the supporting base plate 22. The reinforcing beams 222 enhance the load-bearing capacity of the supporting base plate 22, allowing the operating platform to withstand heavier loads from operators, tools, and parts. This effectively prevents the supporting base plate 22 from deforming or being damaged due to excessive stress, ensuring the operating surface remains flat and providing a stable and reliable working foundation for the operator. The spaced arrangement of the multiple reinforcing beams 222 evenly distributes the load on the operating surface, avoiding localized stress concentration and further improving the structural stability and reliability of the supporting base plate 22.

[0046] In addition, multiple through holes are formed along the height of the support base plate 22. These through holes reduce the weight of the support base plate 22, thereby reducing the overall weight of the operating platform and making it easier to assemble and move, reducing the consumption of manpower and resources. Furthermore, the through holes facilitate drainage; in rainy weather or other humid environments, water can be quickly drained through the through holes, preventing water accumulation on the surface of the support base plate 22, preventing corrosion caused by long-term water accumulation, and extending the service life of the operating platform. Moreover, the through holes can also serve as wiring channels, facilitating the passage of electrical lines during construction, improving the safety and convenience of using the operating platform.

[0047] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
