Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically referring to a steel structure construction platform for building construction. Background Technology

[0002] Various construction platforms are used in the construction process, among which the suspended platform is the most commonly used. The suspended platform is a construction tool for high-altitude operations in construction projects. It is used for curtain wall installation, exterior wall cleaning, and cantilevered structures are erected on buildings or structures. The suspended platform is driven by a lifting mechanism and moves up and down along the facade of the building or structure via steel wire ropes.

[0003] In related technologies, the suspended construction platforms used for building exterior wall construction employ traditional steel wire suspension, with no contact between the construction platform and the working wall. Furthermore, the simple main structure of the construction platform results in poor stability. During operation, the construction platform is prone to tilting or swaying due to worker movement, strong winds at high altitudes, and an unstable center of gravity. The swaying caused by the steel wire rope suspension not only affects the workers' work but also poses a risk of workers falling, thus creating certain safety hazards for construction personnel. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a steel structure construction platform for building construction, which can increase the stability of the construction platform during construction and enhance the safety protection of construction personnel against falls by triggering the unfolding anti-fall net.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a steel structure construction platform for building construction, comprising: a construction platform, an anti-sway support device, a counterweight tool compartment, a fall protection net, a triggering component, a fall protection net fixing component, and a fall protection connection component. The construction platform is provided with horizontal guardrails on both sides, and a receiving cavity is formed at the bottom of one side of the construction platform. The anti-sway support device is disposed within the receiving cavity. The counterweight tool compartment is located on the inner bottom surface of the construction platform and is offset towards the anti-sway support device. A movable cover plate is hinged to the counterweight tool compartment. The fall protection net is disposed on the other side of the construction platform. On one side, the bottom of the fall protection net is hinged to the bottom of the other side of the construction platform. The top two sides of the fall protection net are connected to both ends of the construction platform through connecting components. The fall protection net fixing component is centrally located on the horizontal guardrail on the other side of the construction platform. The horizontal guardrail on this side is connected to the top of the fall protection net through the fall protection net fixing component. The triggering component is connected to the horizontal guardrail on the other side of the construction platform. The triggering component is connected to the fall protection net fixing component. The fall protection connecting component is located inside the construction platform and is connected to the horizontal guardrail on one side of the construction platform.

[0006] Further, the anti-sway support device includes: a hydraulic device, a drive end, and two sets of symmetrically arranged folding support assemblies. The hydraulic device is longitudinally centered within the receiving cavity. The hydraulic device is connected to the bottom of the drive end via a hydraulic rod. The top two sides of the drive end are respectively connected to the two sets of symmetrically arranged folding support assemblies. Each folding support assembly includes: a support base, a support rod, a support portion, a connecting rod, and a pull rod. The support base is bolted to the inner wall of one side of the receiving cavity. The support rod is laterally arranged on one side of the drive end. One end of the support rod is rotatably connected to the support base. One end of the support portion is fixedly connected to the side of the support rod away from the opening of the receiving cavity. The other end of the support portion is rotatably connected to one end of the connecting rod. The other end of the connecting rod is rotatably connected to the bottom of one side of the hydraulic device. The pull rod is located between the drive end and the connecting rod. One end of the pull rod is rotatably connected to the end of the connecting rod near the hydraulic device. The other end of the pull rod is rotatably connected to one side of the drive end.

[0007] Furthermore, the other end of the support rod is provided with an elastic support part, on which a support plate is installed, and multiple sliding rollers are longitudinally distributed on the surface of the support plate.

[0008] Furthermore, the fall arrest net fixing assembly is disposed within the through cavity, which is located in the middle of the transverse guardrail on the other side. The fall arrest net fixing assembly includes a drive gear, a rotating shaft, and a locking device. The two ends of the rotating shaft are rotatably connected to the inner walls of both sides of the through cavity. The locking device is centrally fixed on the rotating shaft and has a locking part that engages with a retaining ring. The retaining ring is fixedly disposed on the top of the fall arrest net facing the construction platform. The drive gears are symmetrically disposed on both sides of the locking device and are fixedly connected to the rotating shaft.

[0009] Furthermore, the triggering component includes: a guard plate, a drive rack, multiple return springs, and multiple limiting slide rods. The guard plate is disposed on the other side of the transverse guardrail. One end of the drive rack is fixedly connected to one side surface of the guard plate, and the other end extends into the through cavity. The drive rack and the drive gear are arranged in a one-to-one correspondence. Multiple return springs are disposed on one side surface of the guard plate, with one end connected to one side surface of the guard plate and the other end connected to the other side of the transverse guardrail. Multiple limiting slide rods and multiple return springs are disposed on the surface of the guard plate on the same side, and each limiting slide rod movably penetrates the other side of the transverse guardrail. Each limiting slide rod has a limiting block at its end.

[0010] Furthermore, when the guard plate receives lateral pressure, the guard plate compresses the return spring, the drive rack meshes with the drive gear, and the snap-fit ​​device separates from the snap ring.

[0011] Furthermore, on the other side, a plurality of trigger springs are fixedly installed on the surface of the horizontal guardrail close to the top of the fall protection net, and the plurality of trigger springs are movably connected to the top of the fall protection net.

[0012] Furthermore, the fall arrestor connection assembly includes: a slide rail, a slider, a safety rope, and a hanging ring, wherein the slide rail is disposed on the inner surface of the transverse guardrail on one side of the construction platform, the slider is slidably connected to the slide rail, one end of the safety rope is connected to the slider, and the other end of the safety rope is connected to the hanging ring.

[0013] Furthermore, an electrical box is installed on the outer surface of the transverse guardrail on one side of the construction platform, and the electrical box is connected to a controller.

[0014] Furthermore, the connecting assembly includes: a first connecting end, a second connecting end, and a steel rope, wherein the first connecting end is fixedly disposed at the top of both ends of the fall protection net, the first connecting end is connected to the second connecting end through the steel rope, and the second connecting end is fixedly disposed at both ends of the construction platform near the fall protection net.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows:

[0016] 1. The working wall is supported by a retractable anti-sway support device. The hydraulic device drives the drive end to unfold the support rods on both sides and support them on the working wall, so that the construction platform is lifted to a certain angle, thereby maintaining the stability of the construction platform and preventing the construction platform from easily shaking due to external factors.

[0017] 2. Triggerable deployable fall protection net: When construction workers collide with one side of the fall protection net due to uncontrollable factors of the main body of the construction platform causing it to sway or for other reasons, the triggering component will open the fall protection net fixing component through a certain degree of impact and compression on the guard plate, thereby releasing and deploying the fall protection net. In the event of an emergency, the fall protection net will be deployed on the outside of the construction platform to provide fall protection and ensure the personal safety of construction workers.

[0018] 3. The fall arrestor connection components installed on the horizontal guardrail can provide additional fall protection for construction workers while they are working on the construction platform, ensuring their freedom of movement within the platform. This is achieved through the traction of the safety rope, which, together with the fall arrestor net, provides dual fall protection and enhances the safety of construction workers.

[0019] 4. The concealed counterweight tool compartment can be used to store construction supplies, avoiding the occupation of the work space on the construction platform. At the same time, by placing construction supplies, the center of gravity of the construction platform is shifted to the side facing the construction wall in conjunction with the anti-sway support device. This causes a certain shift in the center of gravity of the construction platform, increasing the support stability of the anti-sway support device and reducing the impact of strong winds or internal shaking on the overall posture of the construction platform, further increasing the overall stability.

[0020] 5. The longitudinally mounted sliding rollers on the surface of the support plate can adjust the height of the construction platform without retracting the support rods, so that the support rods can provide stable support for the construction platform while moving up and down along the working wall surface with it via the sliding rollers.

[0039] The hydraulic device 5 is longitudinally centered within the receiving cavity 3. The hydraulic device 5 is connected to the bottom of the drive end 4 via a hydraulic rod. The top two sides of the drive end 4 are respectively connected to two symmetrically arranged folding support assemblies 38. Each folding support assembly 38 includes: a support base 6, a support rod 7, a support portion 8, a connecting rod 9, and a pull rod 10. The support base 6 is bolted to the inner wall of one side of the receiving cavity 3. The support rod 7 is laterally arranged on one side of the drive end 4. One end of the support rod 7 is rotatably connected to the support base 6. One end of the support portion 8 is fixedly connected to the side of the support rod 7 away from the opening of the receiving cavity 3. The other end of the support portion 8 is rotatably connected to one end of the connecting rod 9. The other end of the connecting rod is rotatably connected to the bottom of one side of the hydraulic device 5. The pull rod 10 is located between the drive end 4 and the connecting rod 9. One end of the pull rod 10 is rotatably connected to the end of the connecting rod 9 near the hydraulic device 5.

[0040] In one embodiment of the present invention, such as Figure 6 As shown, the other end of the support rod 7 is provided with an elastic support part 11, and a support plate 12 is installed on the elastic support part 11. Multiple sliding rollers 13 are longitudinally distributed on the surface of the support plate 12.

[0041] In one embodiment of the present invention, such as Figures 7-9 As shown, the fall protection net fixing component 31 is disposed in the cavity 32, which is located in the middle of the horizontal guardrail 41 on the other side. The fall protection net fixing component 31 includes a drive gear 27, a rotating shaft 28, and a snap-fit ​​device 29.

[0042] The two ends of the rotating shaft 28 are rotatably connected to the inner walls of the two sides of the cavity 32. The locking device 29 is centrally fixed on the rotating shaft 28. The locking device 29 is provided with a locking part 30, which locks with a retaining ring 16. The retaining ring 16 is fixedly installed on the top of the side of the fall protection net 15 facing the construction platform 1. The drive gears 27 are symmetrically arranged on both sides of the locking device 29 and are fixedly connected to the rotating shaft 28.

[0043] In one embodiment of the present invention, such as Figures 7-9 As shown, the triggering component 26 includes: a guard plate 21, a drive rack 22, multiple reset springs 23, and multiple limit slide bars 24.

[0044] The guard plate 21 is disposed on the transverse guardrail 41 on the other side. One end of the drive rack 22 is fixedly connected to one side surface of the guard plate 21, and the other end of the drive rack 22 extends into the through cavity 32. The drive rack 22 and the drive gear 27 are arranged in a one-to-one correspondence. A plurality of return springs 23 are disposed on one side surface of the guard plate 21. One end of the return spring 23 is connected to one side surface of the guard plate 21, and the other end of the return spring 23 is connected to the transverse guardrail 41 on the other side. A plurality of limiting slide rods 24 and a plurality of return springs 23 are disposed on the surface of the guard plate 21 on the same side, and each limiting slide rod 24 moves through the transverse guardrail 41 on the other side, and each limiting slide rod 24 is provided with a limiting block 25 at its end.

[0045] In one embodiment of the present invention, such as Figure 11 As shown, when the guard plate 21 receives lateral pressure, the guard plate 21 squeezes the return spring 23, the drive rack 22 meshes with the drive gear 27, and the snap-fit ​​device 29 separates from the snap ring 16.

[0046] In one embodiment of the present invention, a plurality of trigger springs (not shown in the figure) are fixedly provided on the side surface of the horizontal guardrail 41 on the other side close to the top of the fall protection net 15, and the plurality of trigger springs are movably connected to the top of the fall protection net 15.

[0047] In one embodiment of the present invention, such as Figure 1As shown, the fall arrestor connection assembly 33 includes: a slide rail 34, a slider 37, a safety rope 35, and a hanging ring 36. The slide rail 34 is disposed on the inner surface of the transverse guardrail 41 on one side of the construction platform 1. The slider 37 is slidably connected to the slide rail 34. One end of the safety rope 35 is connected to the slider 37, and the other end of the safety rope 35 is connected to the hanging ring 36.

[0048] In one embodiment of the present invention, such as Figure 3 As shown, an electrical box 14 is installed on the outer surface of the horizontal guardrail 41 on one side of the construction platform 1, and the electrical box 14 is connected to a controller.

[0049] In one embodiment of the present invention, such as Figure 2 As shown, the connecting assembly 20 includes: a first connecting end 17, a second connecting end 19, and a steel rope 18. The first connecting end 17 is fixedly disposed at the top of both ends of the fall protection net 15. The first connecting end 17 is connected to the second connecting end 19 through the steel rope 18. The second connecting end 19 is fixedly disposed at both ends of the construction platform 1 on the side near the fall protection net 15.

[0050] In summary, the steel structure construction platform for building construction of this invention supports the working wall surface through a retractable anti-sway support device. A hydraulic device drives the drive end to unfold the support rods on both sides and support them against the working wall surface, causing the construction platform to be lifted at a certain angle, thereby maintaining the stability of the construction platform and preventing it from easily swaying due to external factors. A trigger-deployable fall protection net allows for easy deployment. When construction workers collide with the fall protection net due to uncontrollable factors of the construction platform or other reasons, the impact and compression of the guardrail triggers the trigger component to open the fall protection net fixing component, releasing and deploying the fall protection net. This provides fall protection by deploying the fall protection net outside the construction platform in case of danger, ensuring the personal safety of construction workers. The fall protection connection component installed on the horizontal guardrail allows construction workers to move freely within the construction platform while being further protected from falls by safety rope traction. This combination of safety rope and fall protection net provides dual fall protection measures, improving the safety protection effect for construction workers. The concealed counterweight tool compartment can be used to store construction supplies, avoiding the occupation of the work platform's operating space. Simultaneously, by placing the construction supplies, in conjunction with the anti-sway support device, the center of gravity of the construction platform is shifted to the side facing the work wall. This shift in the platform's center of gravity increases the stability of the anti-sway support device and reduces the impact of strong winds or internal swaying on the overall posture of the construction platform, further enhancing overall stability. Longitudinally mounted rollers on the support plate surface allow for height adjustment of the construction platform without retracting the support rods. This enables the support rods to provide stable support for the platform while moving up and down along the work wall via the rollers.

[0051] Working principle: When using the steel structure construction platform of the present invention for building facade construction, the construction personnel first open the movable cover plate 40, put the tools and materials required for construction into the counterweight tool compartment 39, and then fasten the lifting ring 36 to the safety belt worn by the construction personnel. The construction personnel can move freely in the construction platform 1. At the same time, the slider 37 connected to the lifting ring 36 by the safety rope 35 slides along the slide rail 34 as the construction personnel move.

[0052] Next, the construction workers can use hoisting equipment to lower the construction platform 1 to the designated position. Then, the construction workers can operate the controller to activate the hydraulic device 5, which will extend the drive end 4. This will cause the drive end 4 to pull one end of the connecting rod 9 through the pull rod 10, making the connecting rod 9 rotate with the bottom side of the hydraulic device 5 as support. At this time, the other end of the connecting rod 9 will pull the support part 8 installed on one side of the support rod 7, which will cause the support rod 7 to rotate outward with the support seat 6 set on the inner wall of the receiving cavity 3 as the support point, until the support rod 7 is fully extended and parallel to the inner wall of the receiving cavity 3. At this time, the other end of the support rod 7 will abut against the building wall where the work needs to be done, so that the bottom of the main body of the construction platform 1 is tilted outward at a certain angle relative to the top without affecting the work. At this time, the support of the support rod 7 on the building surface makes the construction platform 1 stable and provides a guarantee for the stability of the construction workers.

[0053] Furthermore, when the support rod 7 is supported on the building surface, the support plate 12 installed at the other end of the support rod 7 contacts the building surface, and at the same time, multiple longitudinally arranged sliding rollers 13 installed on its surface roll in contact with the building surface. When the height of the construction platform 1 needs to be adjusted, there is no need to retract the support rod 7. It can be moved up and down directly, so that the support rod 7 can roll up and down along the building surface through the sliding rollers 13, which brings convenience to the use of the construction platform 1.

[0054] When the construction platform 1 shakes violently due to external force or force majeure, or when construction workers lose their balance for other reasons, and the workers hit the guard plate 21 with a certain force, the return spring 23 set between the guard plate 21 and the horizontal guardrail 41 is compressed because the impact force exceeds its elastic support force. At this time, the guard plate 21 moves towards the horizontal guardrail 41 through the limiting slide rod 24, and the drive rack 22 installed on it moves into the receiving cavity 3 until it is driven to rotate by meshing with the drive gear 27. At this time, the drive gear 27 drives the rotating shaft 28 to rotate, which drives the locking device 29 installed on the rotating shaft 28 to rotate. After the rotation angle is reached, the locking part 30 separates from the locking ring 16 set at the top of the fall protection net 15. The fall protection net 15 can automatically unfold after the traction is removed. Under the restriction of the first connecting end 17 and the second connecting end 19 at both ends of the steel rope 18, the fall protection net 15 unfolds to a certain angle and is maintained, so as to realize the fall protection of one side of the construction platform 1 and bring safety guarantee to the construction workers working at height.

[0055] It should be noted that a trigger spring can be installed between the fall protection net 15 and the horizontal guardrail 41 to increase the unfolding speed of the fall protection net 15, changing the unfolding from free fall to pop-out unfolding.

[0056] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
