Description

Technical Field

[0001] This invention relates to the field of construction support technology, and more specifically, to a prefabricated staircase construction support and its construction method. Background Technology

[0002] Prefabricated staircase construction scaffolding is an auxiliary structure specifically designed to support and ensure the safety and stability of prefabricated staircase installation. With the development of the construction industry, prefabricated buildings are gradually becoming a trend. Among them, prefabricated staircases are widely used due to their advantages such as high construction efficiency, stable quality, and material saving. Construction scaffolding is usually made of steel or aluminum alloy materials, which have good load-bearing capacity and rigidity, and can effectively support various parts of the staircase, ensuring its horizontality and verticality during installation. The supporting force of the construction scaffolding makes the prefabricated staircase more stable during the assembly process.

[0003] However, most existing construction scaffolds are built on-site. On the one hand, using on-site scaffolds wastes a lot of assembly time and increases labor costs. On the other hand, it requires the preparation of a large number of assembly parts, which is a cumbersome process. Therefore, it is necessary to create a construction scaffold that does not require assembly and can be quickly used for the assembly of prefabricated stairs. Summary of the Invention

[0014] A method for constructing prefabricated stairs includes the following steps: S1: Site clearing and scaffolding placement. Clear debris and laitance from the floor where the staircase will be installed. Mark the staircase support points. Move the scaffolding to the marked support position. Level the bottom of the main scaffolding to ensure the machine is vertical. Multiple scaffolding sets are evenly distributed according to the staircase span. S2: Coarse adjustment of support height. The operator rotates the winch drive shaft to lift the installation plate through the height adjustment mechanism, adjusting the support plate to be within cm below the bottom surface of the prefabricated staircase, and locking the winch to temporarily fix the height. S3: First-level slope angle adjustment, hoist the prefabricated stair components to the installation elevation, start motor one, worm gear two and gear one drive the adjustment plate to lift, adjust the inclination angle of the main slope of the support plate so that the upper surface of the support plate is in contact with the bottom surface of the stair treads. During the adjustment process, pay attention to the warning mechanism. If the buzzer alarms, immediately reverse the motor one. S4: Secondary rotation angle fine adjustment. If it is an arc-shaped or rotating prefabricated staircase, start motor two, and drive the rotating rod to deflect through the worm gear three meshing half gear, finely adjust the side rotation angle of the support plate, eliminate the gap between the support plate and the bottom surface of the staircase, and ensure that the entire contact surface is evenly stressed. S5: After completing the height and dual-angle adjustment, power off and lock, check the verticality of the support and the elevation of the stairs, complete the grouting of the stairs and the anchoring of the nodes, and let it stand until the strength of the connection nodes meets the standard. S6: After the staircase structure reaches the design strength, first start motor one and motor two to reverse the tilt angle of the support plate, then release the winch lock, rotate the shaft in the opposite direction to lower the height of the installation plate, so that the support plate is removed from the bottom of the staircase, and the whole support is transferred to the next construction floor for reuse.

[0015] The present invention provides a prefabricated staircase construction support and its construction method, the beneficial effects of which include: 1. By setting an angle adjustment mechanism, motor one controls the overall slope of the support plate to match the slope of a conventional straight staircase, while motor two drives the support plate to rotate laterally for fine adjustment, adapting to curved and rotating irregular prefabricated staircases. This allows the support plate to fit completely against the bottom surface of the prefabricated staircase. Compared to traditional fixed-angle brackets, there is no need to replace support components of different specifications. One set of brackets can meet the construction needs of various types of prefabricated staircases, greatly reducing the number of spare parts for the brackets and expanding the applicability of the equipment.

[0016] 2. By setting up an early warning mechanism, when the adjustment angle reaches the equipment's safety threshold, the support plate presses down on the arc-shaped contact block to trigger the touch switch, and the buzzer alarm sounds immediately, forcibly reminding the operator to stop adjusting the angle. This effectively prevents transmission rods such as worm gears, gears, and adjustment plates from bending or breaking due to excessive force, thus protecting the equipment's components.

[0017] 3. By setting up a height adjustment mechanism, when the rotating shaft rotates, it drives the sector gear to move under the meshing action of the worm gear and the sector gear. During the movement of the sector gear, since the outer side of the sector gear is connected to one side of the connecting rod, the angle of the connecting rod changes, thereby causing the other end of the connecting rod to move upward, and finally causing the mounting plate to move upward. Conversely, it causes the mounting plate to move downward, thus achieving the purpose of flexibly adjusting the overall support height of the device. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-8The present invention provides a technical solution: a prefabricated staircase construction support, including a support plate 1, a height adjustment mechanism 2 is provided below the support plate 1, an angle adjustment mechanism 3 is provided between the support plate 1 and the height adjustment mechanism 2, and an early warning mechanism 4 is provided on one side of the height adjustment mechanism 2. The height adjustment mechanism 2 is used to adjust the support height of the support plate 1; The angle adjustment mechanism 3 is used to adjust the support angle of the support plate 1; The warning mechanism 4 is set up to provide early warning when the angle of the support plate 1 is adjusted.

[0023] The system includes a C-shaped frame 31, which is mounted above the height adjustment mechanism 2. A mounting support 32 is fixedly mounted on the top surface of one end of the C-shaped frame 31. A mounting shaft 319 is rotatably mounted inside the mounting support 32. An adjusting plate 33 is provided on the inner side of the mounting support 32. One end of the adjusting plate 33 is fixedly mounted on the outer surface of the mounting shaft 319 and located inside the mounting support 32. Two positioning seats 315 are fixedly mounted on the top surface of the adjusting plate 33. A rotating rod 316 is rotatably mounted inside the positioning seats 315. Two fixing sleeves 317 are fixedly mounted on the outer surface of the rotating rod 316. A support plate 1 is fixedly mounted on the top of the two fixing sleeves 317. A second mounting support 34 is fixedly mounted on the top of the C-shaped frame 31. A first mounting shaft 35 is rotatably mounted inside the second mounting support 34 and located inside the second mounting support 34. A mounting bracket 36 is fixedly fitted onto the outer surface. A gear 37 is fixedly installed at one end of the mounting shaft 35 located outside the mounting support 34. A mounting support 311 is fixedly installed on one side of the C-shaped frame 31. A mounting shaft 312 is rotatably installed inside the mounting support 311. A worm gear 313 is fixedly fitted onto the outer surface of the mounting shaft 312 located inside the mounting support 311. The worm gear 313 meshes with the gear 37. Two positioning frames 38 are fixedly installed on the bottom surface of the adjusting plate 33. A connecting rod 310 is fixedly connected to the outer surface of the mounting bracket 36. Limiting wheels 39 are rotatably installed on both sides of the connecting rod 310. The limiting wheels 39 are rolled and engaged inside the positioning frames 38. A motor 314 is fixedly installed on one side of the mounting support 311. The output end of the motor 314 is fixedly connected to one end of the mounting shaft 312.

[0024] In operation, the device is first moved to the location where the stairs need to be assembled. Then, by starting the motor 314, the meshing between the worm gear 313 and the gear 37 drives the mounting shaft 35 to rotate inside the mounting support 34. This causes the angle of the connecting rod 310 to change, meaning the limit wheel 39 moves along the inside of the positioning frame 38 towards the mounting sleeve 36. This lifts one end of the adjusting plate 33, causing the support plate 1 to tilt towards the mounting support 32. When the appropriate stair assembly angle is reached, the support plate 1 is completely flush with the bottom surface of the prefabricated stairs, providing stable support for the prefabricated stairs. This allows the device to support prefabricated stairs with different slopes during assembly, greatly increasing its overall applicability.

[0025] The outer surface of the mounting shaft 319, located inside the mounting support 32, is fixedly fitted with a worm gear 320. One end of the rotating rod 316 is fixedly fitted with a half gear 318, which meshes with the worm gear 320. A motor 321 is fixedly fitted on one side of the mounting support 32, and the output end of the motor 321 is fixedly connected to one end of the mounting shaft 319. After the top surface of the support plate 1 is in contact with the bottom surface of the prefabricated staircase, the mounting shaft 319 can be rotated by controlling the start of the motor 321. Under the meshing action of the worm gear 320 and the half gear 318, the angle of the support plate 1 can be changed. When facing a rotating and tilting prefabricated staircase, the purpose of stable support can be achieved more accurately, thereby further increasing the overall applicability of the device.

[0026] The height adjustment mechanism 2 includes a main support 21. Two symmetrical uprights 22 are fixedly mounted on the top of the main support 21. A latching bracket 23 is movably engaged with the outer surface of each upright 22. A mounting plate 24 is fixedly mounted on the top of the latching bracket 23. A C-shaped frame 31 is fixedly mounted in the center of the top surface of the mounting plate 24. A protective frame is fixedly mounted between the two uprights 22. Two symmetrical fixing brackets 1 29 and 212 are fixedly mounted inside the protective frame, arranged at right angles. A rotating shaft 25 is rotatably mounted inside the upright 22. A worm gear 27 is fixedly mounted on the outer surface of the rotating shaft 25. The protective frame... A limiting frame 26 is fixedly installed, and a rotating shaft 25 is rotatably installed inside the limiting frame 26 to limit the rotation of the shaft 25. A sector gear 28 is movably installed inside the protective frame, and the sector gear 28 meshes with a worm gear 27. Rollers 211 and 213 are respectively rolled and engaged inside the fixed frame 29 and fixed frame 212. A connecting rod 210 is installed on one side of rollers 211 and 213. The middle part of the connecting rod 210 is movably connected to one side of the sector gear 28. One end of the connecting rod 210 is rotatably connected to a connecting rod 214, and the other end of the connecting rod 214 is connected to the mounting plate 24.

[0027] During operation, when supporting the prefabricated staircase during assembly, simply rotating the shaft 25 causes the worm gear 27 and sector gear 28 to mesh and move. As the sector gear 28 moves, its outer side connects to one side of the connecting rod 210, changing the angle of the connecting rod 210. This causes the other end of the connecting rod 210 to move upwards, ultimately moving the mounting plate 24 upwards. Conversely, moving it downwards causes the mounting plate 24 to move downwards. This allows for flexible adjustment of the overall support height of the device, further expanding its applicability.

[0028] The system includes an L-shaped frame 41, which is fixedly installed on the bottom surface of the mounting plate 24. A base 42 is fixedly installed on the top of the L-shaped frame 41. A touch switch 43 is fixedly installed in the center of the top surface of the base 42. A top frame 46 is provided above the base 42. Multiple springs 410 connect the bottom surface of the top frame 46 and the top surface of the base 42. A plug-in sleeve 47 is fixedly installed in the center of the top surface of the top frame 46. A column 48 is plugged into the inside of the plug-in sleeve 47. An arc-shaped contact block 49 is fixedly installed on the top of the column 48. A touch frame 411 is fixedly installed in the center of the bottom surface of the top frame 46. A buzzer alarm 412 is installed on one side of the frame 41. Multiple external brackets 44 are fixedly installed on the outside of the L-shaped frame 41. Each external bracket 44 has a limit groove 45 inside. A fixing plate 413 is fixedly installed on the outside of the top frame 46. A limit block 414 is fixedly installed on one side of the fixing plate 413. The limit block 414 is movably engaged inside the limit groove 45 to limit the top frame 46. A winch 215 is installed at one end of the rotating shaft 25 to rotate the rotating shaft 25 and limit the rotating shaft 25 after the height is adjusted to the correct position. It can also be connected to an external drive device.

[0029] During operation, as the angle of the support plate 1 changes, when the bottom surface of the support plate 1 contacts the arc-shaped contact block 49, it applies a downward force to the arc-shaped contact block 49. This causes the column 48, the plug sleeve 47, and the top frame 46 to move downwards until the contact frame 411 contacts the contact switch 43. This allows the contact frame 411 to touch the contact point of the contact switch 43, thereby activating the buzzer alarm 412 to sound an alarm. The warning angle is adjusted to its maximum value, thus preventing damage to the equipment due to over-adjustment. After the angle of the support plate 1 is adjusted back, the contact frame 411 separates from the contact point of the contact switch 43 under the reaction force of the spring 410, and the buzzer alarm 412 is turned off. Furthermore, the limit groove 45 and the limit block 414 ensure that the top frame 46 always maintains vertical movement, guaranteeing that the contact frame 411 can accurately press the contact point of the contact switch 43.

[0030] A method for constructing prefabricated stairs includes the following steps: S1: Site clearing and scaffolding placement. Clear debris and laitance from the floor where the staircase will be installed. Mark the staircase support points. Move the scaffolding to the marked support position. Level the bottom of the main scaffolding 21 to ensure the entire machine is vertical. Multiple scaffolding sets are evenly distributed according to the staircase span. S2: Coarse adjustment of support height. The operator rotates the winch 215 to drive the shaft 25, and lifts the mounting plate 24 through the height adjustment mechanism 2. The support plate 1 is adjusted to be 10 to 20 cm lower than the bottom surface of the prefabricated staircase, and the winch 215 is locked to temporarily fix the height. S3: First-level slope angle adjustment, hoist the prefabricated stair components to the installation elevation, start motor 314, worm gear 313 and gear 37 drive the adjustment plate 33 to lift, adjust the inclination angle of the main slope of the support plate 1 so that the upper surface of the support plate is in contact with the bottom surface of the stair treads. During the adjustment process, pay attention to the warning mechanism 4. If the buzzer alarms, immediately reverse the motor 314. S4: Secondary rotation angle fine adjustment. If it is an arc-shaped or rotating prefabricated staircase, start motor 2 321, which drives the rotating rod 316 to deflect through the meshing of the worm gear 320 with the half gear 318. Fine adjust the lateral rotation angle of the support plate 1 to eliminate the gap between the support plate and the bottom surface of the staircase and ensure that the entire contact surface is evenly stressed. S5: After completing the height and dual-angle adjustment, power off and lock, check the verticality of the support and the elevation of the stairs, complete the grouting of the stairs and the anchoring of the nodes, and let it stand until the strength of the connection nodes meets the standard. S6: After the staircase structure reaches the design strength, first start motor one and motor two to reverse the tilt angle of support plate 1, then release the winch lock, rotate shaft 25 in the opposite direction to lower the height of installation plate 24, so that support plate 1 is removed from the bottom of the staircase, and the whole support is transferred to the next construction floor for recycling.

[0031] Specifically, the working process or principle of this prefabricated staircase construction support and its construction method is as follows: Before construction, the entire device is transported to the prefabricated staircase construction site. First, the winch 215 rotates the shaft 25 to drive the height adjustment mechanism 2 to raise and lower the support plate 1, initially adjusting it to near the bottom elevation of the prefabricated staircase. Then, motors 314 and 321 are sequentially activated to drive the angle adjustment mechanism 3 to complete a two-dimensional tilt adjustment, ensuring the support plate 1 is fully in contact with the bottom surface of the staircase. During adjustment, if the support exceeds its tilt limit, the warning mechanism 4 automatically triggers an audible and visual alarm to prevent overload damage. Finally, stable support for the staircase components is achieved. After assembly, the support can be removed by reversing the adjustment mechanism. The main support 21 bears the weight of the entire machine, while the symmetrical uprights 22 on both sides serve as vertical guides. The track is slidably mounted on the outside of the upright 22. The top support mounting plate 24 is connected to the upper angle adjustment mechanism 3. The internal rotating shaft 25 of the protective frame is radially limited by the limiting frame 26. The rotating shaft 25 is fixed to the outside of the rotating shaft 25. The worm gear 27 continuously meshes with the sector gear 28. The winch 215 at the end of the rotating shaft 25 can be manually driven to rotate. When the winch 215 is rotated in the forward direction, the rotating shaft 25 drives the worm gear 27 to rotate, which in turn drives the sector gear 28 to swing. The sector gear 28 pulls the connecting rod 210, which is hinged in the middle, to move horizontally. Rollers 211 and 213 roll and limit the movement of the connecting rod 210 within the right-angled fixed frame 29 and fixed frame 212, respectively, constraining the connecting rod 210 to slide only horizontally. One end of the connecting rod 210 pushes the connecting rod 210. 214 is raised upwards, and connecting rod 214 pushes the mounting plate 24 and the snap-fit ​​bracket 23 to slide upwards along the upright 22, thereby raising the support plate 1 as a whole. The winch 215 is rotated in the opposite direction, the sector gear 28 swings in the opposite direction, and connecting rod 210 pulls connecting rod 214 downwards. The mounting plate 24 and the upper mechanism descend synchronously, completing the adjustment of the support height. After adjusting to the target height, the winch 215 is locked, the rotating shaft 25 is fixed, and the overall support height is locked. The entire device is moved to the position where the stairs need to be assembled. Then, by controlling the start of motor 314, the meshing action between worm gear 313 and gear 37 can drive the mounting shaft 35 to rotate inside the mounting support 34, thereby changing the angle of connecting rod 310. That is, the limiting wheel 39 moves along the inside of the positioning frame 38 towards the mounting bracket 36, thereby lifting one end of the adjusting plate 33, causing the angle of the support plate 1 to tilt towards the mounting support 32. When the appropriate stair assembly angle is adjusted, the support plate 1 is completely in contact with the bottom surface of the prefabricated stair, thus achieving stable support for the prefabricated stair. Furthermore, by controlling the start of the motor 321, the mounting shaft 319 is driven to rotate. Under the meshing action of the worm gear 320 and the half gear 318, the other angle of the support plate 1 can be changed. When facing a rotating and tilting prefabricated stair, the purpose of stable support can be achieved more accurately, thereby further increasing the overall applicability of the device.

[0032] It should be noted that motor 2 321 and motor 1 314 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
