Description

Technical Field

[0001] The present invention belongs to the technical field of construction platforms, and more specifically, relates to a mobile and detachable construction platform. Background Art

[0002] In the field of modern building construction, construction platforms, as key facilities to ensure the safe operation of construction workers and assist in completing various construction tasks, their performance and characteristics have a crucial impact on the smooth progress of the project. For a long time, scaffolding has been commonly used as the main form of construction platform in building construction. Traditional scaffolding usually uses I-beams as the main material, constructs a steel structure platform by welding, simultaneously tension safety nets on the outside to ensure the safety of construction workers, and sets up connecting wall members inside to make a reliable connection with the building structure. However, many drawbacks have emerged during the actual application of this traditional construction platform.

[0003] From the perspective of construction workload and time cost, the construction process of traditional scaffolding is cumbersome and complex. First of all, a large number of I-beams need to be accurately measured, cut and welded. Each welding point requires professional technicians to operate and strict quality inspection to ensure that the welding strength meets the safety standards. This not only consumes a large amount of manpower and time, but also requires a high technical level of construction workers. According to statistics, in some large-scale construction projects, the scaffolding construction work alone may account for 10%-15% of the entire project duration, greatly affecting the project progress. At the same time, since the welding work needs to be carried out on the construction site, it is greatly restricted by environmental factors such as weather conditions and site conditions. Once adverse factors occur, it may lead to construction interruption and further delay the project duration. In terms of cost, the disadvantages of traditional construction platforms are even more prominent. On the one hand, the material cost remains high. As the main material, I-beams are expensive in themselves, and a large amount of material loss will occur during the welding process, resulting in waste of resources. On the other hand, the labor cost cannot be ignored. A large number of professional construction workers are required to build and dismantle the scaffolding. With the continuous increase of labor costs, the proportion of labor costs in the total project cost is getting larger and larger. In addition, since traditional construction platforms are usually used once, after the project is completed, most of the materials cannot be reused and can only be disposed of as waste, further increasing the cost investment. For some small-scale construction enterprises, this high cost investment often brings huge economic pressure to the enterprises. Safety hazards are also a serious problem faced by traditional construction platforms. During the welding operation process, there are various safety risks such as fire and electric shock. The construction site environment is complex, and welding sparks are easy to cause fire accidents, especially in areas with more flammable materials. Once a fire occurs, the consequences will be unimaginable. At the same time, the electrical safety problems of welding equipment cannot be ignored. If the equipment fails or is operated improperly, it is extremely easy to cause electric shock accidents, threatening the lives of construction workers. In addition, during the use of traditional scaffolding, due to the structural stability being affected by various factors such as wind force and load changes, it is easy to have local instability or even overall collapse, posing a serious threat to the lives of construction workers. Summary of the Invention

[0004] In view of this, a mobile and detachable construction platform provided by the present invention solves the disadvantages that traditional building construction platforms are difficult to flexibly adjust according to the required construction height and are inconvenient to disassemble and assemble, and improves the operation efficiency.

[0005] The present invention is implemented as follows:

[0006] The present invention provides a mobile and detachable construction platform, including a base and a construction platform installed above the base, wherein: it includes a connection component installed on the surface of the base; the connection component includes a socket, an H-shaped pipe rack and a hook. Sockets are fixedly installed around the surface of the base. The bottom ends of two horizontally arranged H-shaped pipe racks are inserted into the sockets and fixedly connected by bolts. Hooks are integrally formed on both sides of the construction platform. The construction platform is clamped between two horizontally arranged H-shaped pipe racks through the hooks; a cross support rod is installed between two horizontally arranged H-shaped pipe racks. The connection between the cross support rod and the H-shaped pipe rack is set as a multi-layer sleeve structure. Adjacent sleeves are connected by a catch and a spring. The catch is a fan-shaped structure arranged obliquely.

[0007] The technical effects of the mobile and detachable construction platform provided by the present invention are as follows:

[0008] By setting the connection component, the base, the H-shaped pipe rack and the construction platform form a detachable connection, which is convenient for transportation and storage; the cross support rod and the H-shaped pipe rack adopt a multi-layer sleeve, catch and spring structure. The fan-shaped catch is arranged obliquely and can be automatically clamped when the construction platform is stressed, effectively preventing the cross support rod from tilting, enhancing the overall stability of the construction platform, and improving the safety and reliability of construction.

[0009] On the basis of the above technical solution, the mobile and detachable construction platform of the present invention can also be improved as follows:

[0010] Wherein, a handrail is integrally formed on one side of the top of the H-shaped pipe rack, a socket is arranged on one side of the top end of the H-shaped pipe rack, a slot matching the socket is opened at the bottom end of the H-shaped pipe rack, and two vertically distributed H-shaped pipe racks are mutually inserted and matched through the socket and the slot.

[0011] The beneficial effect of adopting the above improvement scheme is that the handrail integrally formed on one side of the top of the H-shaped pipe rack provides a grasping support point for construction workers, facilitating the movement and operation of construction workers on the platform, effectively preventing construction workers from accidentally falling, and further improving the safety of using the construction platform.

[0012] Further, a socket is arranged on one side of the top end of the H-shaped pipe rack, a slot matching the socket is opened at the bottom end of the H-shaped pipe rack, and two vertically distributed H-shaped pipe racks are mutually inserted and matched through the socket and the slot.

[0013] The beneficial effect of adopting the above improvement scheme is that the socket at the top end of the H-shaped pipe rack and the slot at the bottom end cooperate with each other to realize the rapid insertion of multiple H-shaped pipe racks in the vertical direction. The height of the construction platform can be flexibly adjusted according to construction requirements, improving the applicability and versatility of the construction platform and meeting the requirements of different construction scenarios.

[0014] Further, an installation groove is formed in the outer side wall of the socket joint, and an installation block matching the installation groove is arranged on the inner side wall of the slot formed at the bottom end of the H-shaped pipe rack. The bottom of the upper H-shaped pipe rack among the two vertically distributed H-shaped pipe racks is inserted into the top of the lower H-shaped pipe rack through the installation groove and the installation block, and is fixedly connected through a shaft pin.

[0015] The beneficial effects of adopting the above improvement scheme are as follows: The installation groove on the outer side wall of the socket joint cooperates with the installation block on the inner side wall of the slot and is fixed through a shaft pin, enhancing the connection strength and stability between the vertically connected H-shaped pipe racks, avoiding loosening or falling off during use, and ensuring the structural reliability of the construction platform after height adjustment.

[0016] Further, the ends of the cross support rods are respectively sleeved on the connecting convex columns fixedly installed on the outer side walls of the two horizontally arranged H-shaped pipe racks.

[0017] The beneficial effects of adopting the above improvement scheme are as follows: The ends of the cross support rods are sleeved on the connecting convex columns on the outer side walls of the H-shaped pipe racks, forming a stable support structure with the H-shaped pipe racks, sharing the stress of the construction platform, further enhancing the overall rigidity and anti-deformation ability of the construction platform, and ensuring the stability of the construction platform when carrying heavy objects.

[0018] Further, a limiting piece is rotatably connected to the surface of the connecting convex column through a shaft pin.

[0019] The beneficial effects of adopting the above improvement scheme are as follows: The limiting piece rotatably connected to the surface of the connecting convex column through a shaft pin can limit the rotation angle of the cross support rod, prevent the cross support rod from rotating excessively and affecting the stability of the construction platform, and at the same time, the cross support rod can be folded and stored when not in use, saving space and facilitating transportation and storage.

[0020] Further, it further includes a mobile support assembly installed on the outer side of the base. The mobile support assembly includes a U-shaped frame, a screw rod, an adjusting part, and mobile wheels. The U-shaped frame is slidably connected to the outer side of the base, the screw rod is threadedly connected to the surface of the U-shaped frame, one end of the screw rod is fixedly installed with the adjusting part, the other end of the screw rod penetrates through the surface of the U-shaped frame and extends into the U-shaped frame, and is rotatably connected to the surface of the base through a bearing, and the mobile wheels are installed at the bottom of the base.

[0021] The beneficial effects of adopting the above improvement scheme are as follows: The mobile wheels in the mobile support assembly make the construction platform easy to move and can quickly adjust the construction position; by rotating the adjusting part to drive the screw rod to rotate, the U-shaped frame can be controlled to slide up and down along the outer side of the base, realizing the lifting adjustment of the construction platform, meeting the construction requirements of different heights, and improving the convenience and flexibility of construction.

[0022] Furthermore, a guiding strip is integrally formed on the inner side wall of the U-shaped frame, a guiding groove matching the guiding strip is formed on the outer side wall of the base, the U-shaped frame is slidably connected to the outside of the base through the guiding strip and the guiding groove, the bottom surface of the U-shaped frame extends outward in a horn shape and is provided with anti-slip nails.

[0023] The beneficial effects of adopting the above improvement scheme are as follows: The cooperation between the guiding strip on the inner side wall of the U-shaped frame and the guiding groove on the outer side wall of the base provides guidance for the sliding of the U-shaped frame, ensures the stable operation of the U-shaped frame during the lifting process, avoids shaking or deviation, and improves the accuracy and reliability of the adjustment of the movable support assembly.

[0024] Furthermore, in the multi-layer sleeve structure, grooves for accommodating the springs are arranged at intervals along the circumferential direction on the outer wall of the inner sleeve, one end of each spring abuts against the bottom of the groove, the other end is fixedly connected to the sector-shaped stopper, the sector-shaped stopper can slide in the groove, an arc-shaped through groove for the sector-shaped stopper to extend out and retract is formed at the position corresponding to the sector-shaped stopper on the outer sleeve, and the length of the arc-shaped through groove is adapted to the sliding stroke of the sector-shaped stopper.

[0025] The beneficial effects of adopting the above improvement scheme are as follows: The cooperation between the groove of the inner sleeve, the spring and the sector-shaped stopper enables the stopper to slide in the groove. While ensuring the flexibility of the connection between the cross support rod and the H-shaped pipe rack, the elastic force of the spring enables the stopper to tightly clamp the adjacent sleeve in time, effectively preventing the cross support rod from tilting and enhancing the stability and reliability of the connection structure. The arc-shaped through groove of the outer sleeve provides a sliding space for the sector-shaped stopper, adapts to the sliding stroke of the sector-shaped stopper, ensures that the sector-shaped stopper will not be hindered during the telescoping process, ensures the normal operation of the multi-layer sleeve connection structure, and maintains the stability of the connection between the cross support rod and the H-shaped pipe rack.

[0026] Furthermore, the inclined surface of the sector-shaped stopper faces the outside of the connection between the cross support rod and the H-shaped pipe rack, and the inclination angle is such that when the cross support rod is stressed, the sector-shaped stopper can automatically clamp the adjacent sleeve.

[0027] The beneficial effects of adopting the above improvement scheme are as follows: The inclined surface of the sector-shaped stopper faces the outside and is set at a specific inclination angle, so that when the cross support rod is stressed, the external force will prompt the sector-shaped stopper to further clamp the adjacent sleeve, forming a self-locking effect of being more stable under stress, greatly improving the stability of the connection between the cross support rod and the H-shaped pipe rack, and effectively solving the problem that the traditional support frame is prone to tilting.

[0028] Compared with the prior art, the beneficial effects of a movable and detachable construction platform provided by the present invention are:

[0029] In terms of convenience and flexibility, its mobile support components play a key role. The setting of the mobile wheels enables the construction platform to be easily moved on the construction site. Construction workers can quickly adjust the position of the platform according to the construction progress and work requirements, without having to rebuild it like traditional scaffolding, which greatly improves construction efficiency. At the same time, by turning the adjustment part to drive the screw to rotate, the U-shaped frame can slide up and down along the outside of the base, thereby completing the lifting and lowering adjustment of the construction platform. This function enables the platform to adapt to construction needs at different heights, whether it is lower wall decoration work or higher building main body construction, it can be easily coped with, greatly expanding the scope of application of the platform. In contrast, once the traditional scaffolding is built, it is very difficult to adjust the height, and it often requires reconstruction or complex modifications, which consumes a lot of time and manpower;

[0030] The detachable connection design is another highlight of this platform, which brings significant economic and time benefits. The base, H-shaped pipe rack and construction platform are detachably connected through connecting components. This design allows the platform to be disassembled into multiple parts during transportation and storage, greatly reducing the occupied space. For construction companies, when it is used between different projects, the transportation cost is greatly reduced, and a lot of storage space is also saved. Moreover, the assembly and disassembly process at the construction site is also very simple. It does not require professional welding equipment and complicated operating procedures. Ordinary construction personnel can complete it after simple training, which greatly shortens the construction preparation time and finishing time;

[0031] In terms of safety, this platform provides comprehensive protection through a variety of structural designs. The handrails on the top of the H-shaped pipe rack provide construction workers with a reliable gripping support point. When moving and working on the platform, construction workers can use the handrails to maintain their body balance at any time, effectively preventing accidental falls. The connection structure between the cross support rod and the H-shaped pipe rack adopts an innovative design of multi-layer sleeves and stoppers combined with springs. The fan-shaped stoppers are tilted and can automatically tighten when the construction platform is stressed, forming a self-locking effect that becomes more stable the more stressed it is, greatly enhancing the overall stability of the platform and effectively solving the problem of easy tilting of traditional support frames. In addition, the anti-slip spikes on the bottom of the U-shaped frame and the coordinated design of the guide strips and guide grooves further improve the stability of the platform in a fixed state and the stability during the adjustment process, fully protecting the lives of construction workers.

[0041] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] As Figure 1 shown, it is the first embodiment of a mobile detachable construction platform provided by the present invention. In this embodiment, it includes a base 10 and a construction platform 11 installed above the base 10. Among them: it includes a connection assembly 3 installed on the surface of the base 10; the connection assembly 3 includes an insertion sleeve 31, an H-shaped pipe rack 32 and a hook 33. The insertion sleeves 31 are fixedly installed around the surface of the base 10. The bottom ends of two horizontally arranged H-shaped pipe racks 32 are inserted into the insertion sleeves 31 and are fixedly connected by bolts. Hooks 33 are integrally formed on both sides of the construction platform 11. The construction platform 11 is clamped between two horizontally arranged H-shaped pipe racks 32 through the hooks 33; a cross support rod 36 is installed between two horizontally arranged H-shaped pipe racks 32. The connection part between the cross support rod 36 and the H-shaped pipe rack 32 is set as a multi-layer sleeve structure, and adjacent sleeves are connected by a catch and a spring. The catch is a fan-shaped structure arranged obliquely.

[0043] First, insert the bottom end of the H-shaped pipe rack into the socket of the base and fix it with bolts; then hook the hooks on both sides of the construction platform into the space between the horizontally arranged H-shaped pipe racks; finally, put the multi-layer sleeves at the end of the cross support rod on the connecting convex column 39 of the H-shaped pipe rack. During the installation process, the sector-shaped stopper automatically clamps under the action of the spring, completing the assembly of the construction platform.

[0044] Among them, in the above technical solution, a handrail 34 is integrally formed on one side of the top of the H-shaped pipe rack 32, a socket 35 is arranged on one side of the top end of the H-shaped pipe rack 32, a slot 302 matching the socket 35 is opened at the bottom end of the H-shaped pipe rack 32, and the two vertically distributed H-shaped pipe racks 32 are mutually inserted and matched through the socket 35 and the slot 302.

[0045] A socket 35 is arranged on one side of the top end of the H-shaped pipe rack 32, a slot 302 matching the socket 35 is opened at the bottom end of the H-shaped pipe rack 32, and the two vertically distributed H-shaped pipe racks 32 are mutually inserted and matched through the socket 35 and the slot 302.

[0046] An installation groove 37 is opened on the outer side wall of the socket 35, an installation block 38 matching the installation groove 37 is arranged on the inner side wall of the slot 302 opened at the bottom end of the H-shaped pipe rack 32. For the two vertically distributed H-shaped pipe racks 32, the bottom of the upper H-shaped pipe rack 32 is inserted into the top of the lower H-shaped pipe rack 32 through the installation groove 37 and the installation block 38 and is fixedly connected by a shaft pin.

[0047] The ends of the cross support rods 36 are respectively sleeved on the connecting convex columns 39 fixedly installed on the outer side walls of the two horizontally arranged H-shaped pipe racks 32.

[0048] A limiting piece 301 is rotatably connected to the surface of the connecting convex column 39 through a shaft pin.

[0049] It further includes a mobile support assembly 2 installed outside the base 10. The mobile support assembly 2 includes a U-shaped frame 21, a screw rod 22, an adjusting part 23 and mobile wheels 27. The U-shaped frame 21 is slidably connected to the outside of the base 10. The screw rod 22 is threadedly connected to the surface of the U-shaped frame 21. One end of the screw rod 22 is fixedly installed with the adjusting part 23. The other end of the screw rod 22 penetrates through the surface of the U-shaped frame 21 and extends into the U-shaped frame 21 and is rotatably connected to the surface of the base 10 through a bearing. Mobile wheels 27 are installed at the bottom of the base 10.

[0050] When the construction platform needs to be moved, rotate the adjusting part to raise the U-shaped frame so that the mobile wheels contact the ground, and then the platform can be pushed to move; when the platform needs to be fixed, rotate the adjusting part in the reverse direction to lower the U-shaped frame until the bottom surface of the U-shaped frame contacts the ground and supports the platform, and the mobile wheels are suspended.

[0051] On the inner side wall of the U-shaped frame 21, a guiding strip 24 is integrally formed. On the outer side wall of the base 10, a guiding groove 25 matching the guiding strip 24 is provided. The U-shaped frame 21 is slidably connected to the outer side of the base 10 through the guiding strip 24 and the guiding groove 25. The bottom surface of the U-shaped frame 21 extends outward in a flared shape and is provided with anti-slip nails 26.

[0052] In the multi-layer sleeve structure, on the outer wall of the inner sleeve, grooves for accommodating springs are arranged at intervals in the circumferential direction. One end of the spring abuts against the bottom of the groove, and the other end is fixedly connected to the sector-shaped stopper. The sector-shaped stopper can slide in the groove. At the position corresponding to the sector-shaped stopper on the outer sleeve, an arc-shaped through groove for the sector-shaped stopper to extend out and retract is provided, and the length of the arc-shaped through groove is adapted to the sliding stroke of the sector-shaped stopper.

[0053] The inclined surface of the sector-shaped stopper faces the outside of the connection between the cross support rod 36 and the H-shaped pipe rack 32. The inclination angle is such that when the cross support rod 36 is stressed, the sector-shaped stopper can automatically clamp the adjacent sleeve.

[0054] The following is a detailed description of the specific implementation manners of the above steps:

[0055] Installation of the movable support assembly: First, install the movable wheels at appropriate positions at the bottom of the base to ensure that the movable wheels rotate flexibly. Then, the U-shaped frame is slidably installed on the outer side of the base through the cooperation of the guiding strip and the guiding groove on the outer side of the base, so that the U-shaped frame can slide smoothly along the guiding groove. Next, pass the screw through the threaded hole on the surface of the U-shaped frame, fix one end to the adjusting part, and the other end is rotatably connected to the surface of the base through a bearing. Rotate the adjusting part to test whether the U-shaped frame can slide up and down smoothly to ensure that the movable support assembly is installed correctly. At this time, according to actual needs, adjust the height of the U-shaped frame by rotating the adjusting part so that the movable wheels contact the ground (for a movable platform) or the anti-slip nails on the bottom surface of the U-shaped frame contact the ground (for a fixed platform).

[0056] Calculation equation for the lifting and lowering adjustment efficiency of the movable support assembly:

[0057]

[0058] In the formula: E m is the lifting and lowering adjustment efficiency of the movable support assembly, which reflects the speed and operation convenience of realizing the lifting and lowering of the U-shaped frame by rotating the adjusting part. The higher the efficiency, the more lifting and lowering adjustment operations can be completed in the same time. v m is the lifting and lowering speed of the U-shaped frame, with the unit of millimeter per minute. Its magnitude is related to factors such as the pitch and rotation speed of the screw. The larger the pitch and the faster the rotation speed, the faster the lifting and lowering speed of the U-shaped frame. n m is the number of turns of the adjusting part. The more turns of rotation, the greater the theoretical lifting and lowering distance of the U-shaped frame, but it also means an increase in operation time and affects the adjustment efficiency as the denominator in the formula. T mThe time required to adjust the lifting of the U-shaped frame, in minutes, includes the operation time for the operator to rotate the adjustment part and the movement time during the lifting of the U-shaped frame, etc.

[0059] Installation of the H-shaped pipe rack: Insert the bottom end of the horizontally arranged H-shaped pipe rack into the socket sleeves around the surface of the base. Use bolts to fixedly connect the H-shaped pipe rack and the socket sleeve to ensure firm connection. The tightening torque of the bolts is determined according to the material strength and force conditions in accordance with relevant mechanical design specifications. If it is necessary to adjust the height of the construction platform, insert the vertically arranged H-shaped pipe rack into the slot of the lower H-shaped pipe rack through the plug connector, so that the installation block is embedded in the installation groove, and then use a shaft pin to pass through the corresponding installation holes to fixedly connect the upper and lower H-shaped pipe racks. Repeat this operation until the required construction platform height is reached to form a stable H-shaped pipe rack frame structure.

[0060] Calculation equation for the connection stability coefficient of the H-shaped pipe rack:

[0061]

[0062] In the formula: S h is the connection stability coefficient of the H-shaped pipe rack, which is used to measure the stability degree of the H-shaped pipe rack connection structure when bearing loads. The larger the coefficient, the more stable the connection structure. F j is the ultimate shear force that a single connection part (such as the cooperation between the plug connector and the slot, and the installation groove and the installation block) can bear. Its value depends on factors such as the shear strength of the material and the contact area of the connection part, and reflects the bearing capacity of the connection structure itself. n is the number of connection parts of the H-shaped pipe rack. The more connection parts, the higher the stability of the overall structure. μ h is the friction coefficient between the connection parts of the H-shaped pipe rack, which is related to the surface roughness and material properties of the connection components. The larger the friction coefficient, the less likely the connection parts are to have relative sliding, thereby improving the stability. F z is the total load applied to the H-shaped pipe rack, including the gravity generated by the construction platform, construction personnel and equipment, as well as external forces such as wind loads that may be received. h h is the height of the H-shaped pipe rack. The higher the height, the more likely the structure is to shake or become unstable under the action of the same load. Therefore, the height affects the stability coefficient as the denominator in the formula. k h is the correction coefficient for the geometric shape and connection method of the H-shaped pipe rack. Considering the enhancing effect of the unique shape design of the H-shaped pipe rack (such as structures like plug connectors and slots) on stability, this coefficient is greater than 1, and the specific value can be determined by methods such as experiments or finite element analysis.

[0063] Cross support rod installation: Put the multi-layer sleeve at the end of the cross support rod on the connecting boss on the outer wall of the H-shaped pipe rack. During the installation process, the fan-shaped block automatically extends out of the arc groove of the outer sleeve under the action of the spring, and clamps with the adjacent sleeve to achieve a stable connection between the cross support rod and the H-shaped pipe rack. Adjust the position of the cross support rod to make it at a suitable angle, and then install the limit plate on the connecting boss through the axle pin to limit the rotation angle of the cross support rod and ensure that the cross support rod plays a stable supporting role. At the same time, the angle of the cross support rod can be appropriately adjusted according to the actual force conditions to optimize the overall force distribution of the platform.

[0064] Calculation equation for the self-locking stability coefficient of the cross support rod:

[0065]

[0066] Where: S s F is the cross support rod self-locking stability coefficient, which is used to evaluate the ability of the cross support rod to maintain stability through the self-locking structure when subjected to force. The higher the coefficient, the better the self-locking effect and the stronger the platform stability. t is the elastic force applied by the spring to the fan-shaped stopper. The magnitude of the elastic force is related to the elastic coefficient and compression of the spring. The greater the elastic force, the greater the force of the fan-shaped stopper to clamp the adjacent sleeve, and the more helpful it is to achieve self-locking. α is the inclination angle of the fan-shaped stopper. The inclination angle determines the efficiency of converting external force into clamping force. The larger the angle, the greater the clamping force of the stopper under the same external force. However, too large an angle may affect the convenience of installation, so it is necessary to consider the design comprehensively. k s It is the correction factor of the multi-layer sleeve structure and the shape of the stopper. Taking into account the influence of the number of sleeve layers, material and the fan-shaped structure of the stopper on the self-locking performance, this coefficient is determined through experiments or theoretical analysis and is used to correct the calculation results. l It is the external force acting on the cross support rod, such as the lateral force on the construction platform, the impact force generated by the movement of construction personnel, etc. s It is the sleeve diameter at the connection between the cross support rod and the H-shaped pipe rack. The larger the diameter, the greater the torque on the sleeve under the same external force, which is not conducive to the self-locking stability, so it is used as the denominator in the formula.

[0067] Installation of the construction platform: Align the hooks on both sides of the construction platform with the two horizontally set H-shaped pipe racks, move the construction platform downward, and connect the hooks to the H-shaped pipe racks, ensuring that the hooks fit closely with the H-shaped pipe racks and the construction platform is installed firmly. Construction workers can then work on the construction platform, and can hold the handrails on the top of the H-shaped pipe racks at any time during the work process to ensure their own safety.

[0068] During the installation and use of the entire construction platform, each component cooperates with each other, giving full play to its structural advantages, realizing the functions of the construction platform being convenient for disassembly and assembly according to the required construction height, easy disassembly and assembly, convenient movement and support, effectively solving the problems existing in the traditional construction platform, such as large engineering quantity, high cost, poor safety, etc., and having significant technical advantages and practical value.

[0069] Specifically, the principle of the present invention is as follows:

[0070] The design of the connection component is the core to achieve the detachable connection and stable support of the platform. The insertion fit between the insertion sleeve and the H-shaped pipe rack, as well as the bolt fixation, provides a solid installation foundation for the H-shaped pipe rack. This connection method is not only convenient for the installation and disassembly of the H-shaped pipe rack, but also can bear a certain load, ensuring the stability of the platform during use. The construction platform is clamped with the horizontally arranged H-shaped pipe rack through a hook, forming a reliable horizontal connection, enabling the construction platform to be firmly installed on the H-shaped pipe rack and bearing the weight of construction personnel and construction equipment. The connection between the cross support rod and the H-shaped pipe rack adopts a multi-layer sleeve structure, and its technical principle lies in using the interaction between the clamping block and the spring to achieve the stability and flexibility of the connection. The groove of the inner sleeve is used to accommodate the spring and the sector clamping block, and the spring provides an elastic force, enabling the sector clamping block to slide in the groove. When the cross support rod is subjected to an external force, the sector clamping block extends out of the arc-shaped through groove of the outer sleeve under the push of the spring and clamps with the adjacent sleeve. Due to the inclined setting of the sector clamping block, the external force will prompt it to clamp further, forming a self-locking effect, thereby effectively preventing the cross support rod from tilting and enhancing the overall rigidity and stability of the platform;

[0071] The design of the H-shaped pipe rack cleverly solves the problems of platform height adjustment and connection strength. The mutual cooperation between the insertion joint and the insertion slot, as well as the cooperation between the installation slot and the installation block, and then fixed by a shaft pin, realizes the rapid insertion and firm connection of multiple H-shaped pipe racks in the vertical direction. This design enables the construction platform to flexibly adjust the height according to the construction requirements and meet the requirements of different construction scenarios. During the height adjustment process, the insertion joint is inserted into the insertion slot, the installation block is embedded in the installation slot, and the shaft pin passes through the installation hole to fix the two, forming a stable connection structure that can bear large vertical and horizontal loads, ensuring the safety and stability of the platform at different heights;

[0072] The design of the mobile support component integrates mechanical transmission and mechanical principles. The setting of the mobile wheels enables the platform to move freely on the ground, and its rolling friction is much smaller than the sliding friction between the traditional scaffolding and the ground, greatly reducing the manpower and material resources required for the mobile platform. The threaded connection between the screw rod and the U-shaped frame, as well as the bearing rotational connection between the screw rod and the base, constitute a simple and effective lifting and adjusting mechanism. When the adjusting part is rotated, the screw rod rotates. Since the U-shaped frame is threadedly connected to the screw rod, the U-shaped frame will move up and down along the axis of the screw rod. The cooperation between the guiding strip and the guiding groove provides precise guidance for the sliding of the U-shaped frame, ensuring that the U-shaped frame will not shake or deviate during the lifting process.

[0073] The following provides a specific Embodiment 2 of the present invention: As Figure 1 shown; a mobile detachable construction platform, including a base 1 and a construction platform 11 installed above the base 1.

[0074] In this implementation: Some platforms generally adopt an I-beam welded steel structure platform, with a safety net externally tensioned and wall connecting members internally provided for reliable connection with the structure. The project volume is large, the manufacturing and installation time of the platform is long, the cost is high, and material waste is serious. There are great safety hazards during welding, polluting the environment, uneconomical for single use, and unable to be reused. Such construction cost input is large, the efficiency is low, and the construction period is long. On this basis, a connection component 3 is added, and through this component, it is convenient to erect according to the construction requirements.

[0075] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 shown: In order to facilitate erection according to the construction, it further includes a connection component 3 installed on the surface of the base 1. The connection component 3 includes a socket 31, an H-shaped pipe rack 32, and a hook 33. Socket 31 is fixedly installed around the surface of the base 1. The bottom ends of two horizontally arranged H-shaped pipe racks 32 are inserted into the socket 31 and fixedly connected by bolts. Hooks 33 are integrally formed on both sides of the construction platform 11, and the construction platform 11 is clamped between two horizontally arranged H-shaped pipe racks 32 through the hooks 33.

[0076] In this implementation: When erecting the construction platform 11, first insert the bottom ends of the two H-shaped pipe racks 32 into the socket 31 fixedly installed around the surface of the base 1 and fixedly connect them by bolts, so that the two H-shaped pipe racks 32 are horizontally distributed. At this time, the construction platform 11 can be clamped between two horizontally arranged H-shaped pipe racks 32 through the integrally formed hooks 33 on itself, thereby facilitating the installation of the construction platform 11. And through the clamping and bolt fixed connection methods, it can be easily disassembled and assembled according to the construction requirements.

[0077] It should be noted that: on one side of the top of the H-shaped pipe support 32, a handrail 34 is integrally formed. On the one hand, it is convenient to take the H-shaped pipe support 32 through the handrail 34. On the other hand, it is convenient to fasten the safety rope of the construction worker on the handrail 34 to improve the safety of the operators.

[0078] In an alternative embodiment: on one side of the top end of the H-shaped pipe support 32, a socket 35 is provided, and a slot 302 matching the socket 35 is opened at the bottom end of the H-shaped pipe support 32. The two vertically distributed H-shaped pipe supports 32 are mutually plugged and matched through the socket 35 and the slot 302.

[0079] In this embodiment: based on this setting, it is convenient to set up the required height by mutually plugging and matching the two vertically distributed H-shaped pipe supports 32 through the socket 35 and the slot 302 according to the actual height of the construction, and set up the construction platform 11 in the manner described in the above embodiment.

[0080] In an alternative embodiment: an installation groove 37 is opened on the outer side wall of the socket 35, and an installation block 38 matching the installation groove 37 is provided on the inner side wall of the slot 302 opened at the bottom end of the H-shaped pipe support 32. For the two vertically distributed H-shaped pipe supports 32, the bottom of the upper H-shaped pipe support 32 is plugged into the top of the lower H-shaped pipe support 32 through the installation groove 37 and the installation block 38, and is fixedly connected by a shaft pin.

[0081] In this embodiment: based on this setting, it is convenient to set up the required height by mutually plugging and matching the two vertically distributed H-shaped pipe supports 32 through the installation groove 37 opened on the outer side wall of the socket 35 and the installation block 38 provided on the inner side wall of the slot 302 opened at the bottom end of the H-shaped pipe support 32. At the same time, the installation block 38 and the installation groove 37 can conduct installation guidance, which is convenient to connect the two vertically distributed H-shaped pipe supports 32. And by the way of fixing with a shaft pin, it is convenient to disassemble and assemble the two vertically distributed H-shaped pipe supports 32.

[0082] In an alternative embodiment: between the two horizontally arranged H-shaped pipe supports 32, a cross support rod 36 is installed, and the ends of the cross support rod 36 are respectively sleeved on the connecting convex columns 39 fixedly installed on the outer side walls of the two horizontally arranged H-shaped pipe supports 32.

[0083] In this embodiment: based on this setting, it is convenient to strengthen the stability between the two horizontally arranged H-shaped pipe supports 32 by the provided cross support rod 36.

[0084] In an alternative embodiment: a limiting piece 301 is rotatably connected to the surface of the connecting convex column 39 by a shaft pin.

[0085] In this embodiment: Based on this setting, it is convenient to install (see the attached Figure 4 ) The state of the limit piece 301 is convenient for installation. After the cross support rod 36 is connected to the connecting boss 39 between the two horizontally arranged H-shaped pipe racks 32 (see the attached Figure 5 ), rotating the limit plate 301 to this position can prevent the cross support rod 36 from falling.

[0086] like Figure 1 , Figure 2 and Figure 3 As shown: In combination with the above content, in order to facilitate the movement and erection of the platform, it also includes a mobile support assembly 2 installed on the outside of the base 1, and the mobile support assembly 2 includes a U-shaped frame 21, a screw 22, an adjustment portion 23, and a moving wheel 27. The outside of the base 1 is slidably connected to the U-shaped frame 21, and the surface of the U-shaped frame 21 is threadedly connected to the screw 22, one end of the screw 22 is fixedly installed with the adjustment portion 23, and the other end of the screw 22 passes through the surface of the U-shaped frame 21 and extends into the U-shaped frame 21, and is rotatably connected to the surface of the base 1 through a bearing, and a moving wheel 27 is installed at the bottom of the base 1.

[0087] In this embodiment: when the platform is moved, the screw 22 is driven to rotate on the surface of the U-shaped frame 21 by rotating the adjustment part 23 at one end of the screw 22. At this time, the base 1 at one end of the screw 22 can slide inside the U-shaped frame 21 until the moving wheel 27 installed at the bottom of the base 1 is in contact with the ground, thereby facilitating the movement of the platform. Conversely, the screw 22 is rotated in the opposite direction to disengage the moving wheel 27 from the bottom surface, so that the U-shaped frame 21 can be stably supported on the bottom surface, so as to facilitate the stable erection of the platform.

[0088] In an optional embodiment: the inner wall of the U-shaped frame 21 is integrally formed with a guide bar 24, the outer wall of the base 1 is provided with a guide groove 25 matching the guide bar 24, and the U-shaped frame 21 is slidably connected to the outer side of the base 1 through the guide bar 24 and the guide groove 25.

[0089] In this embodiment: Based on this arrangement, when one end of the screw rod 22 pushes the base 1 to slide to one side in the U-shaped frame 21, the guide bar 24 and the guide groove 25 are arranged, so that the base 1 can move smoothly inside the U-shaped frame 21.

[0090] It should be noted that the bottom surface of the U-shaped frame 21 extends outward in a trumpet shape and is provided with anti-slip spikes 26. Through this arrangement, the contact area with the ground can be increased. At the same time, the anti-slip spikes 26 can further improve the stability of the platform during erection and prevent the platform from shifting.

[0091] When erecting the construction platform 11, first, the bottom ends of the two H-shaped pipe racks 32 are inserted into the plug sleeves 31 fixedly installed on the surface of the base 1 on all sides, and are fixedly connected by bolts, so that the two H-shaped pipe racks 32 are horizontally distributed. At this time, the construction platform 11 can be clamped between the two horizontally arranged H-shaped pipe racks 32 through its own integrally formed hook 33, so as to facilitate the installation of the construction platform 11, and through the clamping and bolting fixed connection, it can be conveniently disassembled and assembled according to the needs of the construction, and the two vertically distributed H-shaped pipe racks 32 are plugged and matched with each other through the plug joint 35 and the slot 302. The cross support rod 36 is arranged to strengthen the stability between the two horizontally arranged H-shaped pipe frames 32. When the platform is moved, the adjusting portion 23 at one end of the screw rod 22 is rotated to drive the screw rod 22 to rotate on the surface of the U-shaped frame 21. At this time, the base 1 at one end of the screw rod 22 can slide inside the U-shaped frame 21 until the moving wheel 27 installed at the bottom of the base 1 is connected to the ground, thereby facilitating the movement of the platform. Conversely, the screw rod 22 is rotated in the opposite direction to disengage the moving wheel 27 from the bottom surface so that the U-shaped frame 21 can be stably supported on the bottom surface, so as to facilitate the stable erection of the platform.
