Description

Technical Field

[0001] This application relates to the field of construction scaffolding technology, and more specifically, to a safe construction scaffolding for building construction. Background Technology

[0002] Construction work includes wall masonry and surface plastering. During construction, workers need to use scaffolding as the construction height changes. Traditional scaffolding designs are simple in structure and easy to assemble and transport. However, the platforms on the scaffolding cannot be freely adjusted during use. As a result, workers of different heights may have to work in a semi-squatting position due to the unreasonable platform height. Furthermore, construction materials need to be carried to the high platform each time, leading to increased construction difficulty, high labor intensity, and slow construction progress. In addition, the scaffolding itself is not stable enough and is prone to tipping over and other safety issues. In view of this, we propose a safe construction scaffolding for building construction. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a safe construction scaffold for building construction, which solves the technical problems mentioned in the background. This scaffold achieves two adjustable vertical installation heights by using an electric cylinder to drive the inner guide frame to slide along the outer guide frame, and by using a motor to drive the lead screw to rotate, which in turn forces the construction platform to slide along the inner guide frame. This allows for flexible use, adapting to various construction height requirements, facilitating the stacking of building materials and personnel access, and greatly improving construction efficiency. When the construction platform is raised, rotating the bidirectional screw causes the rotating plates at the four corners of the H-shaped base frame to rotate and unfold. Rotating the threaded rod causes the anti-slip block to press against the ground, making the entire scaffold more stable on the ground. Compared with traditional simple construction scaffolds, the stability is greatly improved, effectively preventing the scaffold from tipping over, resulting in a safer and more reliable technical effect.

[0005] 2. Technical Solution

[0006] This application provides a safety construction frame for building construction, comprising: an H-shaped base frame, a power supply control box, an outer guide frame and two electric cylinders fixedly mounted on the upper surface of the H-shaped base frame, an inner guide frame slidably mounted inside the outer guide frame, the piston rod end of the electric cylinders being fixedly connected to the inner guide frame, a construction platform slidably mounted on the inner guide frame, a lifting mechanism being installed between the construction platform and the inner guide frame, and a support mechanism being installed on the H-shaped base frame;

[0007] The lifting mechanism includes a motor, which is fixedly installed on the construction platform. The output end of the motor moves through the construction platform and is fixedly connected to a lead screw, which is threadedly connected to the inner guide frame.

[0008] The support mechanism includes a bidirectional screw, which is rotatably connected to an H-shaped base frame. The bidirectional screw is threadedly connected to two sliding plates, each of which is slidably connected to the H-shaped base frame. Two T-shaped shafts are slidably mounted on the sliding plates, and a rotating plate is rotatably connected to the bottom end of each T-shaped shaft. A rotating shaft is rotatably connected to the middle of the rotating plate and the H-shaped base frame. A threaded rod is threadedly installed at the end of the rotating plate away from the sliding plate, and an anti-slip block is rotatably mounted at the bottom end of the threaded rod.

[0009] By adopting the above technical solution, the construction scaffold is equipped with an outer guide frame and two electric cylinders fixedly mounted on an H-shaped base frame. A remote control switch for the electric cylinders is installed on the power supply control box. The piston rod of the electric cylinder drives the inner guide frame to slide vertically along the outer guide frame. A construction platform is installed on the inner guide frame, which drives the construction platform to rise and fall. A motor is fixedly installed on the bottom of the construction platform. The motor drives the lead screw to rotate. Since the lead screw is threadedly connected to the inner guide frame, it forces the construction platform to slide vertically along the inner guide frame. This allows for free adjustment of the construction platform in two vertical directions, enabling the construction platform to be lowered to near the ground for easy stacking of building materials and construction tools. The installation height of the construction platform can be freely adjusted according to construction needs. When the construction platform is raised, rotating the bidirectional screw causes the two sliding plates to shift in opposite directions, increasing the angle of the two rotating plates connected to each sliding plate. By rotating the threaded rod, the anti-slip block connected to the bottom of the threaded rod is pressed against the ground, thus stabilizing the entire construction scaffold. Compared with traditional simple construction scaffolds, the stability is greatly improved, effectively preventing the construction scaffold from tipping over.

[0010] Optionally, two rollers are rotatably mounted on one end of the H-shaped base frame, and two omnidirectional wheels are rotatably mounted on the other end of the H-shaped base frame.

[0011] By adopting the above technical solution, the H-shaped base frame can be easily pushed and moved on the construction site by rotating and installing two rollers and two universal wheels. When construction is required, the threaded rod is rotated so that the anti-slip block connected to the bottom of the threaded rod presses against the ground, thereby making the entire construction frame stable.

[0012] Optionally, the inner walls on both sides of the H-shaped bottom frame are provided with first sliding grooves, and the two ends of the sliding plate are fixed with sliding strips, which are slidably installed along the first sliding grooves.

[0013] By adopting the above technical solution, when the bidirectional screw is rotated, the threads at both ends of the bidirectional screw are opposite, which can force the two slide plates to slide in the opposite direction along the H-shaped bottom frame. This can change the angle of the two rotating plates connected to each slide plate, increase the unfolding angle of the rotating plates, and enhance the stability of the overall construction frame after the anti-slip block is pressed against the ground.

[0014] Optionally, each of the slide plates is provided with a strip groove, and the T-shaped shaft is slidably installed along the strip groove.

[0015] By adopting the above technical solution, when the slide plate slides along the H-shaped bottom frame, the slide plate forces the two T-shaped axes to move in opposite directions through the strip groove, thereby changing the relative angle of the two rotating plates.

[0016] Optionally, each of the four upright beams of the outer guide frame is provided with a second sliding groove, and each of the four upright beams of the inner guide frame is fixedly provided with a sliding strip, which is slidably installed along the corresponding second sliding groove.

[0017] By adopting the above technical solution, when the piston rod of the electric cylinder extends or retracts, the inner guide frame can slide along the four vertical beams of the outer guide frame through four sliding strips, thereby driving the motor and the construction platform to rise and fall together.

[0018] Optionally, a third sliding groove is provided at each of the four upright beams of the inner guide frame, and two rectangular grooves are provided on the construction platform. The construction platform is movably fitted onto the outside of the four upright beams of the outer guide frame through the rectangular grooves. A sliding seat is fixedly provided in each of the rectangular grooves, and the sliding seat is slidably disposed in the corresponding third sliding groove. A railing is fixedly provided on the upper surface of the construction platform.

[0019] By adopting the above technical solution, when the piston rod of the electric cylinder extends or retracts, the construction platform is movably fitted onto the four vertical beams of the outer guide frame through the rectangular groove, so that the construction platform can smoothly achieve lifting and lowering. When the motor rotates, because the lead screw is threadedly connected to the inner guide frame, the lead screw will drive the construction platform to slide along the inner guide frame through the slide block during the lifting and lowering process of the inner guide frame.

[0020] 3. Beneficial effects

[0021] One or more technical solutions provided in this application have at least the following technical effects or advantages: The construction scaffold is driven by an electric cylinder to slide the inner guide frame along the outer guide frame, and by a motor to drive the screw to rotate, the construction platform can also be forced to slide along the inner guide frame, enabling the construction platform to freely adjust to two vertical installation heights. It is flexible in use, adapts to various height construction needs, facilitates the stacking of building materials and the entry and exit of personnel, and greatly improves construction efficiency. When the construction platform is raised, the rotating plates at the four corners of the H-shaped bottom frame are rotated and unfolded by rotating the bidirectional screw. By rotating the threaded rod, the anti-slip block is pressed against the ground, making the entire construction scaffold more stable on the ground. Compared with traditional simple construction scaffolds, the stability is greatly improved, effectively preventing the construction scaffold from tipping over, making it safer and more reliable to use.

Detailed Implementation

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 4 This application provides a safety construction frame for building construction, comprising: an H-shaped base frame 1, a power supply control box 8, an outer guide frame 3 and two electric cylinders 5 fixedly mounted on the upper surface of the H-shaped base frame 1, an inner guide frame 4 slidably mounted inside the outer guide frame 3, the piston rod end of the electric cylinders 5 being fixedly connected to the inner guide frame 4, a construction platform 6 slidably mounted on the inner guide frame 4, a lifting mechanism 7 being installed between the construction platform 6 and the inner guide frame 4, and a support mechanism 2 being installed on the H-shaped base frame 1;

[0029] The lifting mechanism 7 includes a motor 71, which is fixedly installed on the construction platform 6. The output end of the motor 71 moves through the construction platform 6 and is fixedly connected to a lead screw 72, which is threadedly connected to the inner guide frame 4.

[0030] Support mechanism 2 includes a bidirectional screw 21, which is rotatably connected to the H-shaped base frame 1. The bidirectional screw 21 is threadedly connected to two sliding plates 22, each of which is slidably connected to the H-shaped base frame 1. Two T-shaped shafts 23 are slidably mounted on the sliding plates 22, and each T-shaped shaft 23 has a rotating plate 24 rotatably connected to its bottom end. A rotating shaft 241 is rotatably connected to the middle of the rotating plate 24 and the H-shaped base frame 1. A threaded rod 25 is threadedly installed at the end of the rotating plate 24 away from the sliding plates 22, and an anti-slip block 251 is rotatably mounted at the bottom end of the threaded rod 25. The construction frame is equipped with an outer guide frame 3 and two electric cylinders 5 fixedly mounted on the H-shaped base frame 1. A remote control switch is installed on the electric cylinders 5 in the power supply control box 8. The piston rod of the electric cylinders 5 drives the inner guide frame 4 to slide vertically along the outer guide frame 3. A construction platform 6 is mounted on the inner guide frame 4, which can be raised and lowered. A motor 71 is fixedly installed on the bottom of the construction platform 6. The motor 71 drives the lead screw 72 to rotate. Since the lead screw 72 is threadedly connected to the inner guide frame 4, the construction platform 6 can be forced to slide vertically along the inner guide frame 4. This allows the construction platform 6 to be freely adjusted in two vertical directions, enabling it to be lowered to near the ground for easy stacking of building materials and construction tools. The installation height of the construction platform 6 can also be freely adjusted according to construction needs. When the construction platform 6 is raised, the two sliding plates 22 are displaced in opposite directions by rotating the bidirectional screw 21. The angle of the two rotating plates 24 connected to each sliding plate 22 increases. By rotating the threaded rod 25, the anti-slip block 251 connected to the bottom of the threaded rod 25 is pressed against the ground, thus stabilizing the entire construction frame. Compared with traditional simple construction frames, the stability is greatly improved, effectively preventing the construction frame from tipping over.

[0031] Reference Figure 1 and Figure 2 Two rollers 11 are rotatably installed at one end of the H-shaped base frame 1, and two casters 12 are rotatably installed at the other end of the H-shaped base frame 1. The H-shaped base frame 1 can be easily pushed and moved on the construction site by rotatably installing two rollers 11 and two casters 12. When construction is required, the threaded rod 25 is rotated so that the anti-slip block 251 connected to the bottom end of the threaded rod 25 is pressed against the ground, thereby making the entire construction frame stable.

[0032] Reference Figure 2 and Figure 3 The inner walls on both sides of the H-shaped base frame 1 are provided with first sliding grooves 13. Sliding strips are fixed at both ends of the sliding plate 22 and are slidably installed along the first sliding grooves 13. When the bidirectional screw 21 is rotated, the threads at both ends of the bidirectional screw 21 are opposite, which can force the two sliding plates 22 to slide in the opposite direction along the H-shaped base frame 1. This can change the angle of the two rotating plates 24 connected to each sliding plate 22. The unfolding angle of the rotating plates 24 becomes larger, and after the anti-sliding block 251 is pressed against the ground, the stability of the overall construction frame can be enhanced.

[0033] Reference Figure 2 and Figure 3 Each slide plate 22 has a strip groove 221. The T-shaped shaft 23 is slidably installed along the strip groove 221. When the slide plate 22 slides along the H-shaped bottom frame 1, the slide plate 22 forces the two T-shaped shafts 23 to move in opposite directions through the strip groove 221, thereby changing the relative angle of the two rotating plates 24.

[0034] Reference Figure 2 and Figure 3 The outer guide frame 3 has a second slide groove 31 at each of the four upright beams, and the inner guide frame 4 has a slide bar fixed at each of the four upright beams and is slidably installed along the corresponding second slide groove 31. When the piston rod of the electric cylinder 5 extends or retracts, the inner guide frame 4 can slide along the four upright beams of the outer guide frame 3 through the four slide bars, thereby driving the motor 71 and the construction platform 6 to rise and fall together.

[0035] Reference Figure 1 and Figure 4 The inner guide frame 4 has a third slide groove 41 at each of the four upright beams. The construction platform 6 has two rectangular grooves 63. The construction platform 6 is movably fitted onto the outside of the four upright beams of the outer guide frame 3 through the rectangular grooves 63. A slide seat 631 is fixed in each of the rectangular grooves 63. The slide seat 631 is slidably installed in the corresponding third slide groove 41. A railing 62 is fixed on the upper surface of the construction platform 6. When the piston rod of the electric cylinder 5 extends or retracts, the construction platform 6 is movably fitted onto the outside of the four upright beams of the outer guide frame 3 through the rectangular grooves 63, so that the construction platform 6 can smoothly achieve lifting and lowering. When the motor 71 rotates, because the lead screw 72 is threadedly connected to the inner guide frame 4, the lead screw 72 will drive the construction platform 6 to slide along the inner guide frame 4 through the slide seat 631 during the lifting and lowering process of the inner guide frame 4.

[0036] Working principle: When this construction scaffold is in use, a remote control switch for the electric cylinder 5 is connected to the power supply control box 8. This allows for remote control of the operation of the electric cylinder 5 and motor 71. The piston rod of the electric cylinder 5 extends and retracts, causing the inner guide frame 4 to slide vertically along the outer guide frame 3. The inner guide frame 4 drives the construction platform 6 and motor 71 to move together. The motor 71 drives the lead screw 72 to rotate. Because the lead screw 72 is threadedly connected to the inner guide frame 4, it forces the construction platform 6 to slide vertically along the inner guide frame 4. This allows the construction platform 6 to be freely adjusted to a position close to ground level, facilitating quick access for construction personnel. It facilitates the easy stacking of building materials and placement of construction tools. Construction workers can then freely adjust the installation height of the construction platform 6 according to the required construction height, allowing them to work while standing. When the construction platform 6 is raised, rotating the bidirectional screw 21 causes the two sliding plates 22 to shift in opposite directions, increasing the angle of the two rotating plates 24 connected to each sliding plate 22. By rotating the threaded rod 25, the anti-slip block 251 connected to the bottom of the threaded rod 25 is pressed against the ground, thus stabilizing the entire construction frame. Compared with traditional simple construction frames, the stability is greatly improved, effectively preventing the construction frame from tipping over.
