Since the installation nodes of PC stairs are interlayer installations, in order to ensure that the concrete strength meets the requirements and the structural safety is ensured, for example, the lifting of PC stairs from the second floor to the third floor is carried out after the concrete pouring of the third floor is completed. Therefore, before the concrete is poured on the construction layer, the stairwell is in an overhead state, involving safety hazards on the edge.

[0003] Based on this phenomenon, the conventional response method is to use a steel pipe rack to fill the space to obtain safety. However, this method needs to be dismantled during the installation of the PC stairs and needs to be re-erected after the installation is completed, which makes installation and disassembly more inconvenient.

[0024] Beneficial effects

[0025] The present invention provides a PC stairwell tool-type operating platform. Compared with the existing technology, it has the following advantages:

[0026] Beneficial effects:

[0027] 1. The PC stairwell tool-type operating platform clamps the vertical steel frame from the left and right sides through repositionable clamping plates, and is suitable for vertical steel frames of different widths. The vertical steel frame can be clamped and fixed at the front and back positions through clamping blocks and bolts, and can adapt to steel frames of different thicknesses, thereby realizing that temporary stairs can be fixed on steel frames of different sizes.

When the hexagonal screw is tightened, the main block and the adjusting block are squeezed by the hexagonal screw, thereby limiting the rotation between the main block and the adjusting block, thereby achieving the effect of fixing the fixing component by the hexagonal screw.

[0029] 3. The PC stairwell tool-type operating platform achieves a very stable effect after the position of the fixed component is adjusted by ensuring that the fixed component will not slide easily when it is not moving due to the action of its own gravity when the adjusting block stops moving.

[0030] 4. The PC stairwell tool-type operating platform can increase the length of the temporary stairs composed of the side rods and the moving rods by moving the moving rod outwards. The second screw is rotated to drive the clamping rod to move outwards. The teeth on the outside of the clamping rod are engaged with the teeth inside the limit groove to fix the slider and the movable pedal, thereby realizing that it can be used for installation platforms at different distances.

[0031] 5. The PC stairwell tool-type operating platform, when the platform is uneven, the raised part will lift the corresponding adaptive plate. The lifted adaptive plate can better fit with the platform, so that the stabilizing shell and the vertical steel frame above remain vertical, thereby improving the stability of the overall installation.

They are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present application. The terms "install", "connect", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be directly connected, or indirectly connected through an intermediate medium, or they can be internal connections between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] The present application will be further described in detail below through the accompanying drawings and examples.

[0046] Reference Figures 1 to 10 The embodiment of the present application provides a PC stairwell tool-type operating platform, including a stairwell 1, with mounting platforms 4 fixedly installed alternately on the left and right inner walls of the stairwell 1, a PC staircase 5 fixedly installed between two adjacent mounting platforms 4, a bracket assembly 2 is provided between the mounting platforms 4, a position adjustment assembly 6 is provided inside the bracket assembly 2, a fixing assembly 7 is provided outside the position adjustment assembly 6, an angle adjustment assembly 8 is provided between the position adjustment assembly 6 and the fixing assembly 7, a temporary support assembly 9 is provided between the position adjustment assemblies 6, and a stabilizing assembly 3 is provided at the bottom of the bracket assembly 2;

[0047] The position adjustment assembly 6 includes an adjustment groove 61, a rack 62 is fixedly installed inside the adjustment groove 61, an adjustment block 63 is slidably connected to the outside of the rack 62, a rotating ring 65 is rotatably connected inside the adjustment block 63, a fixed block 67 is fixedly installed inside the adjustment block 63, the fixed block 67 is located on the inner side of the rotating ring 65, a flat volute spring 66 is fixedly installed between the rotating ring 65 and the fixed block 67, a limiting tooth 64 is fixedly installed on the bottom of the rotating ring 65, and the limiting tooth 64 is engaged with the rack 62.

[0048] In this embodiment, after the horizontal and vertical steel frames are fixed, when the temporary support assembly 9 is fixed, the adjustment block 63 slides inside the adjustment groove 61 to adjust the position of the fixing assembly 7, so that the fixing assembly 7 can correspond to the vertical steel frame 22 that needs to be fixed. When the adjustment block 63 slides, the rack 62 will move the limit tooth 64, and the limit tooth 64 can be normally moved under the action of the flat spiral spring 66, so that the adjustment block 63 can move normally. When the adjustment block 63 stops moving, the elastic force of the flat spiral spring 66 cannot be broken through by the action of the fixed assembly 7's own gravity, so that the fixed assembly 7 will not slide easily when it is not moving, thereby achieving a very stable effect after the position of the fixed assembly 7 is adjusted.

[0049] Reference Figures 1 to 10 In one aspect of this embodiment, the angle adjustment assembly 8 includes a sleeve 81, which is rotatably connected to the front of the adjustment block 63, and the front of the sleeve 81 is fixedly mounted on the back of the main block 71. A screw hole 82 is provided inside the adjustment block 63, and a countersunk hole 83 is provided inside the main block 71. The sleeve 81, the screw hole 82, and the countersunk hole 83 are located corresponding to each other. A hexagon socket screw 84 is provided inside the sleeve 81, the screw hole 82, and the countersunk hole 83. The hexagon socket screw 84 is screwed into the inside of the screw hole 82, and the end face of the hexagon socket screw 84 contacts the rack 62 inside the adjustment block 63. The nut of the screw hole 82 is located inside the countersunk hole 83, and the front of the hexagon socket screw 84 is flush with the front of the main block 71.

[0050] In this embodiment, after the position adjustment of the fixing component 7 is completed, the angle of the fixing component 7 can be adjusted by rotating the sleeve 81 around the adjusting block 63, so that when facing the inclined vertical steel frame 22, it can also ensure that it is aligned with the vertical steel frame 22. After the angle and position of the fixing component 7 are adjusted, by tightening the hexagon socket screw 84, the inside of the hexagon socket screw 84 will be against the front of the rack 62 after the hexagon socket screw 84 is tightened. At this time, the adjusting block 63 and the rack 62 are fixed together by the hexagon socket screw 84, so that it can withstand the weight of the temporary support component 9, and when the hexagon socket screw 84 is tightened, the main block 71 and the adjusting block 63 are squeezed by the hexagon socket screw 84, thereby limiting the rotation between the main block 71 and the adjusting block 63, thereby achieving the effect of fixing the fixing component 7 by the hexagon socket screw 84.

[0051] Reference Figures 1 to 10 The first and second bolts 77 are screwed to the sides of the clamping block 72, and the second and third bolts 77 are screwed to the sides of the clamping block 72.

[0052] When the second bolt 77 is screwed into the slot 73 , the first screw 74 is rotated to adjust the position of the clamping plate 76 . The second bolt 77 is screwed into the slot 73 to adjust the position of the clamping plate 76 . The angle between the clamping block 72 and the main block 71 can be changed. The clamping plate 76 that can change its position can clamp the vertical steel frame 22 from the left and right sides, and can be suitable for vertical steel frames 22 of different widths. The front and rear positions of the vertical steel frame 22 can be clamped and fixed by the clamping block 72 and the second bolt 77 , and can be adapted to steel frames of different thicknesses. This enables the temporary support assembly 9 to be fixed on steel frames of different sizes, and can also be conveniently fixed when facing vertical steel frames 22 of different intervals. There is no need to drill additional holes on the vertical steel frame 22, and the effect of convenient fixing is achieved.

[0053] Reference Figures 1 to 10 In one aspect of this embodiment, the stabilizing assembly 3 includes a stabilizing shell 31, which is fixedly mounted on the bottom of the vertical steel frame 22. The interior of the stabilizing shell 31 is elastically connected to an adaptive rod 36 through a spring 37. An adaptive plate 35 is fixedly mounted on the bottom of the adaptive rod 36. The adaptive plates 35 are evenly arranged on the bottom of the stabilizing shell 31. Side panels 32 are movably mounted on the left and right side walls of the stabilizing shell 31. A card plate 38 is fixedly mounted between the two side panels 32. A card slot 39 is provided inside the card plate 38. The adaptive plate 35 passes through the corresponding card slot 39. Grooves that cooperate with the card plate 38 are evenly provided on the outside of the adaptive plate 35. A moving block 33 is fixedly mounted on the bottom of the side panel 32. The right side of the stabilizing shell 31 is rotatably connected to a first bolt 34, which is screwed through the interior of the moving block 33.

[0054] In this embodiment, when installing the vertical steel frame 22, the stabilizing component 3 is installed at the bottom of the vertical steel frame 22. When the placement platform is uneven, the raised part will lift the corresponding adaptive plate 35. The lifted adaptive plate 35 can better fit the placement platform, so that the stabilizing shell 31 and the vertical steel frame 22 above remain vertical, thereby improving the stability of the overall installation. After the adaptation is completed, the moving block 33 is driven to move by rotating the second bolt. When the moving block 33 moves, it drives the side panel 32 and the card plate 38 to move. The card plate 38 is clamped in the groove on the outside of the corresponding adaptive rod 36 through the card slot 39, thereby fixing the position of the adaptive plate 35, thereby realizing automatic adaptation to the flatness of the installation surface, making the installation more stable.

[0055] Reference Figures 1 to 10In one aspect of this embodiment, the temporary support assembly 9 includes two side rods 91, the adjustment slot 61 is fixedly mounted on the outer side of the side rod 91, a fixed pedal 94 is fixedly mounted between the two side rods 91, a moving rod 92 is movably mounted inside the side rod 91, a movable pedal 93 is movably mounted between the two moving rods 92, and sliders 95 are fixedly mounted on both sides of the movable pedal 93. The slider 95 is slidably connected to the inside of the moving rod 92, and the inside of the moving rod 92 is movably connected to a clamping rod 96. A limiting groove 97 is provided inside the slider 95, and the clamping rod 96 is inserted into the corresponding limiting groove 97. The end face of the moving rod 92 is rotatably connected to a second screw 98, and the second screw 98 is screwed through the interior of the adjacent temporary support assembly 9. The outer side of the clamping rod 96 and the inner wall of the limiting groove 97 are provided with mutually matching clamping teeth.

[0056] In this embodiment, by moving the moving rod 92 out from the inside of the side rod 91, the length of the temporary staircase composed of the side rod 91 and the moving rod 92 can be increased. When adjusting the length of the moving rod 92, the slider 95 slides inside the moving rod 92 to adjust the distance between adjacent movable pedals 93, so that it can be ensured that when folded, it will not block the contraction of the moving rod 92. When unfolded, the movable pedals 93 can be evenly arranged between the moving rods 92 so that they can be used normally. After the position adjustment of the movable pedal 93 is completed, the second screw 98 is rotated to drive the clamping rod 96 to move outward, and the clamping teeth on the outside of the clamping rod 96 are clamped into the clamping teeth inside the limit groove 97 to complete the fixation of the slider 95 and the movable pedal 93, thereby achieving its applicability to installation platforms 4 at different distances.

[0057] All electrical equipment in this solution are powered by external power supplies.

[0058] Working principle: After the horizontal and vertical steel frames are fixed, when the temporary support assembly 9 is fixed, the adjusting block 63 slides inside the adjusting slot 61 to adjust the position of the fixing assembly 7 so that the fixing assembly 7 can correspond to the vertical steel frame 22 that needs to be fixed. When the adjusting block 63 slides, the rack 62 will toggle the limiting tooth 64. The limiting tooth 64 can be toggled normally under the action of the plane volute spring 66, so that the adjusting block 63 can move normally. When the adjusting block 63 stops moving, the fixing assembly 7 cannot break through the elastic force of the plane volute spring 66 under the action of its own gravity, so that the fixing assembly 7 will not slide easily when it is not moving, thereby achieving a very stable effect after the position of the fixing assembly 7 is adjusted. The sleeve 81 surrounds the adjusting block 6 The angle of the fixing assembly 7 can be adjusted by rotating, so that when facing the inclined vertical steel frame 22, it can also ensure that it is aligned with the vertical steel frame 22. After the angle and position of the fixing assembly 7 are adjusted, the hexagon socket screw 84 is tightened. After the hexagon socket screw 84 is tightened, the inner part of the hexagon socket screw 84 will abut the front surface of the rack 62. At this time, the adjusting block 63 and the rack 62 are fixed together by the hexagon socket screw 84, so that they can bear the weight of the temporary support assembly 9. When the hexagon socket screw 84 is tightened, the main block 71 and the adjusting block 63 are squeezed by the hexagon socket screw 84, thereby limiting the rotation between the main block 71 and the adjusting block 63, thereby achieving the effect of fixing the fixing assembly 7 by the hexagon socket screw 84. The button drives the first screw 74 to rotate. The first screw 74 can adjust the position of the clamping plate 76 when rotating. By passing the second bolt 77 through the interior of the connecting groove 73 and then screwing it to the interior of the clamping plate 76, the angle between the clamping block 72 and the main block 71 can be changed. The clamping plate 76 that can change its position clamps the vertical steel frame 22 from the left and right sides, and can be suitable for vertical steel frames 22 of different widths. The clamping block 72 and the second bolt 77 can clamp and fix the front and rear positions of the vertical steel frame 22, and can adapt to steel frames of different thicknesses, thereby realizing that the temporary support assembly 9 can be fixed to steel frames of different sizes, and it can also be convenient to fix when facing vertical steel frames 22 with different intervals, without the need for additional drilling holes on the vertical steel frame 22 to achieve fixation. The convenient effect is that when installing the vertical steel frame 22, the stabilizing component 3 is installed at the bottom of the vertical steel frame 22. When the placement platform is uneven, the raised part will lift the corresponding adaptive plate 35. The lifted adaptive plate 35 can better fit the placement platform, so that the stabilizing shell 31 and the vertical steel frame 22 above remain vertical, thereby improving the stability of the overall installation. After the adaptation is completed, the moving block 33 is driven to move by rotating the second bolt. The moving block 33 drives the side panel 32 and the card plate 38 to move when moving. The card plate 38 is connected to the groove on the outside of the corresponding adaptive rod 36 through the card slot 39, thereby fixing the position of the adaptive plate 35, thereby realizing automatic adaptation to the flatness of the installation surface, making the installation more stable.By moving the moving rod 92 out from the inside of the side rod 91, the length of the temporary staircase composed of the side rod 91 and the moving rod 92 can be increased after the moving rod 92 is moved out. When adjusting the length of the moving rod 92, the distance between adjacent movable pedals 93 can be adjusted by sliding the slider 95 inside the moving rod 92, so that it can be ensured that when it is folded, it will not block the contraction of the moving rod 92. When it is unfolded, the movable pedals 93 can be evenly arranged between the moving rods 92 so that they can be used normally. After the position of the movable pedal 93 is adjusted, the second screw 98 is rotated to drive the clamping rod 96 to move outward, and the clamping teeth on the outside of the clamping rod 96 are clamped into the clamping teeth inside the limiting groove 97 to complete the fixing of the slider 95 and the movable pedal 93, thereby achieving its application to installation platforms 4 at different distances.
