Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and in particular relates to a prefabricated device for assembled building stair slabs and a method for using the same. Background Art

[0002] Prefabricated building design refers to transferring a large amount of on-site work in traditional construction methods to factories, processing and manufacturing building components and accessories in factories, transporting them to the construction site, and assembling and installing them on site through reliable connection methods. Stairs are also a type of prefabricated building design. With the development of science and technology, prefabricated building design devices have developed to a great extent. Its development has brought great convenience to people in building construction, and its types and quantities are also increasing day by day.

[0003] Since building stair slabs are usually assembled together in a splicing manner during prefabrication and installation, during the hoisting process, operators are required to use alignment devices to ensure that the two sections of stairs can be perfectly docked together, and then spliced ​​to form a longer staircase for temporary use by construction workers. However, during the hoisting of the stairs, if instruments are used for tracking and proofreading, there may be a problem that the suspended stair module hits the observer, which may cause a safety accident, so improvements are needed. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention adopts the following technical solution to solve its technical problems: a prefabricated device for assembled building stair treads, comprising connecting components and assembled stairs: the connecting components comprise an inclined connecting plate, both ends of the inclined connecting plate are fixedly connected to a docking plug plate, both sides of the inner wall of the inclined connecting plate are provided with a through socket, the top of the inner wall of the inclined connecting plate is provided with a rotation cut slot, the top of the inner wall of the inclined connecting plate is provided with a transfer component through the rotation cut slot, the bottom of the inner wall of the inclined connecting plate is evenly provided with connecting sockets, the bottom of the inner wall of the inclined connecting plate is provided with a receiving component through the connecting socket, both sides of the upper surface of the inclined connecting plate are provided with a debris removal component, and the front and rear sides of the surface of the inclined connecting plate are symmetrically provided with stabilizing components; the assembled stairs comprise customized stair plates, the customized Both ends of the step plate are fixedly connected with docking plugs, and the surface of the docking plug is slidably connected to the inner wall of the docking plug plate; the assembled steps and connecting parts of the device are two independent structures before assembly. When a temporary staircase needs to be installed at a designated location for construction work, the required installation position of each connecting part and assembled step is first calculated, and then the side of the connecting part is first fixed to the wall of the installation position. After each connecting part is fixed, each assembled step is installed in the position between the connecting parts on both sides, that is, the docking plugs on both sides of each customized step plate are inserted from top to bottom into the docking interface of the docking plug plate through the relevant suspension device. At this time, the supporting parts below provide support for each section of the assembled step, and then the connection points of the assembled steps and the connecting parts are reinforced to obtain the assembled stair plate. The device is assembled in sections by assembling, and the installation position of each assembled ladder can be located by first installing the connecting parts, and then the assembled ladder and the connecting parts can be docked and installed by hoisting. Since the socket of the docking plug plate corresponds to the protrusion of the docking plug, the proofreading and installation can be carried out quickly, avoiding the problem of multiple movements and adjustments of the suspension device, which may cause the assembled ladder to shake and injure people.

[0005] Furthermore, the transfer component includes a friction belt, both ends of the inner wall of the friction belt are rollingly connected to a power shaft, both ends of the power shaft are fixedly connected to a torque motor, the surface of the power shaft is rotatably connected to a load-bearing plate, the inner wall of the load-bearing plate is evenly provided with passive rollers, flat shells are provided on both sides of the bottom of the friction belt surface, the inner wall of the flat shell is fixedly connected to a pressure-sensitive element, one side of the surface of the pressure-sensitive element is fixedly connected to a guide plate, and the end of the guide plate away from the pressure-sensitive element is fixedly connected to a current alarm. When climbing the stairs, the user performs the climbing action on each customized stair board. When moving to the upper surface of the inclined connecting plate, the user stands on the left side of the upper surface of the friction belt through the friction between their feet and the upper surface of the friction belt. Then, the torque motors on both sides control the friction belt to rotate clockwise by rotating the power shaft, thereby transporting the user above the friction belt from bottom to top, saving the user's physical strength. Even if the transfer component of a certain connecting component fails and cannot be used, the user can still walk along the upper surface of the friction belt to the customized stair board on the next level. When passing through the connecting component, the user can use the rotating friction belt to move, thereby achieving an effortless effect, making it easier for the user to climb higher stairs. Because the power shafts and load-bearing plates on both sides provide support for the walking person, in order to avoid the problem of the transfer component collapsing, the current alarm at the bottom can more sensitively determine whether the load-bearing plate has slipped, thereby avoiding this safety accident in advance.

[0006] Furthermore, the supporting component includes a bent support plate, the upper surface of which is evenly distributed with vertical inserts. Side clips are fixedly connected to both sides of the vertical inserts. A flexible sleeve is fixedly connected to the lower surface of the side clips, and the inner wall of the flexible sleeve is fixedly connected to a pressure rod. If the transfer component collapses, the descending power shaft and bearing plate will squeeze the flat sleeves on both sides, compressing the pressure-sensitive elements and activating the current alarm through the conductive plate, thereby preventing pedestrians from passing through the connecting component and thus preventing accidents until the safety hazard is resolved. The supporting component of this device is used to support the assembled stairs on both sides. Even if the assembled stairs become loose from the wall, the bent support plate can simply secure the assembled stairs to prevent them from falling. If the bent support plate and the inclined connecting plate become loose, the inclined connecting plate and the bent support plate can be connected together through the side clips, and the pressure rod can promptly notify maintenance personnel to reinforce them, thereby making the staircase structure more stable.

[0007] Furthermore, there are two docking plates, the bottom of which is fixedly connected to the upper surface of the bent support plate. The front and rear sides of the bent support plate are both fixedly connected to the wall. Both sides of the vertical plug surface are fixedly connected to the inner wall of the connecting socket. The lower surface of the flexible sleeve contacts the bottom of the inner wall of the inclined connecting plate. The surface of the friction belt is slidably connected to the top of the inner wall of the inclined connecting plate via a rotary cut groove. Both ends of the power shaft extend to the outside of the inclined connecting plate through the through socket. The surface of the torque motor is fixedly connected to the surface of the inclined connecting plate. The bottom of the flat housing surface is fixedly connected to the bottom of the inner wall of the inclined connecting plate. The bottom of the current alarm surface is fixedly connected to the bottom of the inner wall of the inclined connecting plate. After the docking plug is inserted into the hole of the docking plate, both sides of the upper surface of the bending tray are squeezed against the lower surface of the customized step plate. Since the vertical plug block is fixed to the connecting socket, the inclined connecting plate pulls the customized step plate upward for support through the bending tray, so the bending tray must remain fixed. When the bending tray becomes loose, the vertical plug block cannot pull the bending tray, so the bending tray will pull the side clamping plate down through the side clamping plate, thereby causing the soft tube sleeve to press down on the bottom of the inner wall of the inclined connecting plate. Since the soft tube sleeve is a hose, the pressure rod inside it will be squeezed, thereby reminding the maintenance personnel to perform maintenance work.

[0008] Furthermore, the impurity removal component includes an arc-surface fixing bar, a parallel empty shell is fixedly connected to one side of the surface of the arc-surface fixing bar, a pressure push rod is slidably connected to the side of the inner wall of the parallel empty shell away from the arc-surface fixing bar, return springs are provided on both sides of the surface of the pressure push rod, a blower is fixedly connected to the side of the inner wall of the parallel empty shell away from the pressure push rod, and an arc-shaped guide plate is fixedly connected to the bottom of the blower surface. If garbage impurities appear on the upper surface of the friction belt, the garbage will be squeezed against the pressure push rod during the rotation of the friction belt, and then the pressure push rod will be squeezed toward the side close to the blower. At this time, the switch of the blower is squeezed and activated, and then air is sucked out through the air inlet at the top and ejected outward through the arc-shaped guide plate at the bottom, thereby blowing away the garbage blocked by the pressure push rod and the arc-surface fixing bar, and falling to both sides along the surface of the friction belt, thereby achieving a cleaning effect.

[0009] Furthermore, there are two dust removal components. The lower surface of the curved fixing strip is fixedly connected to the upper surface of the inclined connecting plate. The top of the blower extends to the exterior of the parallel shell. One end of the return spring is fixedly connected to the inner wall of the parallel shell, and the other end of the return spring is fixedly connected to the surface of the pressure push rod. Because the upper surface of the friction belt is prone to dust and garbage accumulation, which in turn interferes with the rotation of the friction belt, dust removal components are provided on both sides. When garbage accumulates to a certain height, the blower is automatically triggered. Following the guide line of the curved guide plate, the wind can blow the garbage along the upper surface of the friction belt, achieving a dust removal effect while saving electricity.

[0010] Furthermore, the stabilizing component includes a side frame, a viewer fixedly connected to the middle of the side frame's inner wall, and telescopic suction cups evenly arranged on the surface of the viewer. Adjustable telescopic rods are fixedly connected to both sides of the side frame's inner wall, and a meter bar is fixedly connected to the top of the viewer surface. The inclined connecting plate is fixed to the wall via the side frames on both sides. After the ends of the side frames are installed inside the inclined connecting plate, the side frames can slide along the inner wall of the inclined connecting plate a certain distance before being fixed to the inner wall of the inclined connecting plate by adjusting the telescopic rods. Therefore, the gap between the side frames and the inclined connecting plate can be adjusted, thereby facilitating the installation of additional equipment such as side-fixed steel bars, thereby reinforcing the device. The suction surface of the telescopic suction cups contacts the inclined connecting plate. If the fixed inclined connecting plate shakes, the inclined connecting plate will squeeze the viewer on the corresponding side through the telescopic suction cups, causing the viewer reading to change. Maintenance personnel can quickly determine whether the device is securely installed by observing the viewer reading.

[0011] Furthermore, both ends of the side frame extend into the interior of the inclined connecting plate. One end of the adjustable telescopic rod is fixedly connected to the inner wall of the side frame, and the other end of the adjustable telescopic rod is plugged into the inner wall of the inclined connecting plate. The side of the telescopic suction cup away from the observer is engaged with the surface of the inclined connecting plate. There are two side frames, and the surface of each side frame is fixedly connected to the wall. To facilitate inspection work by maintenance personnel, stabilizing components on both sides can automatically record the changing meter readings after the inclined connecting plate is shaken. This allows maintenance personnel to quickly determine whether the device is securely installed by observing the observer's readings, thereby enabling rapid observation of each section of stair components, thereby saving work time and improving the reliability of the device.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device is assembled in sections by assembling, and the installation position of each assembled ladder can be located by first installing the connecting parts, and then the assembled ladder and the connecting parts are docked and installed by hoisting. Since the socket of the docking plate corresponds to the protrusion of the docking plug, the proofreading and installation can be carried out quickly, avoiding the problem of multiple movements and adjustments of the suspension device, which may cause the assembled ladder to shake and injure people.

[0014] 2. When passing through the connecting parts, the user can use the rotating friction belt to move, thereby achieving a labor-saving effect, which makes it easier for the user to climb higher stairs. Since the power shafts and load-bearing plates on both sides provide support for the walking people, in order to avoid the problem of collapse of the transfer parts, the current alarm at the bottom can more sensitively determine whether the load-bearing plate has slipped, thereby avoiding this safety hazard in advance.

[0015] 3. The supporting parts of the device are used to support the assembled stairs on both sides. Even if the assembled stairs become loose from the wall, the bent support plate can simply fix the assembled stairs to prevent the assembled stairs from falling directly. When the bent support plate and the inclined connecting plate become loose, the inclined connecting plate and the bent support plate can be connected together through the side clamping plate, and the maintenance personnel can be notified in time through the compression rod to reinforce them, so that the stairs composed of the device are more stable.

[0016] 4. Since dust or garbage easily accumulates on the upper surface of the friction belt, which interferes with the rotation of the friction belt, debris removal components are set on both sides. When the garbage accumulates to a certain height, the blower will be automatically triggered, and the wind force can blow the garbage along the upper surface of the friction belt along the guide line of the arc guide plate, thereby achieving the debris removal effect while saving electricity.

[0017] 5. In order to facilitate the inspection work of maintenance personnel, the stabilizing components on both sides can automatically record the changes in the instrument readings after the inclined connecting plate is shaken, so that maintenance personnel can quickly judge whether the device is installed firmly by observing the readings of the observer, and then quickly observe the stair components of each section, thereby saving work time and improving the reliability of the device.

[0031] The assembled ladder 2 includes a customized ladder plate 21, and both ends of the customized ladder plate 21 are fixedly connected to a docking plug 22, and the surface of the docking plug 22 is slidably connected to the inner wall of the docking plug plate 15;

[0032] The transfer component 3 includes a friction belt 31, both ends of the inner wall of the friction belt 31 are rollingly connected to the power shaft 32, both ends of the power shaft 32 are fixedly connected to the torque motor 33, the surface of the power shaft 32 is rotatably connected to the load-bearing plate 34, the inner wall of the load-bearing plate 34 is evenly provided with passive rollers 35, and flat shells 39 are provided on both sides of the bottom of the surface of the friction belt 31, the inner wall of the flat shell 39 is fixedly connected to the pressure-sensitive element 38, one side of the surface of the pressure-sensitive element 38 is fixedly connected to the guide plate 37, and the end of the guide plate 37 away from the pressure-sensitive element 38 is fixedly connected to the current alarm 36.

[0033] The receiving component 4 includes a bent support plate 41, and vertical plug blocks 42 are evenly arranged on the upper surface of the bent support plate 41. Side clamps 43 are fixedly connected to both sides of the surface of the vertical plug blocks 42. The lower surface of the side clamps 43 is fixedly connected to a soft tube sleeve 44, and the inner wall of the soft tube sleeve 44 is fixedly connected to a pressure rod 45.

[0034] There are two docking plates 15, the bottom of the docking plate 15 is fixedly connected to the upper surface of the bent support plate 41, the front and rear sides of the surface of the bent support plate 41 are fixedly connected to the wall, both sides of the surface of the vertical plug 42 are fixedly connected to the inner wall of the connecting socket 14, and the lower surface of the soft tube sleeve 44 is in contact with the bottom of the inner wall of the inclined connecting plate 11.

[0035] The surface of the friction belt 31 is slidably connected to the top of the inner wall of the inclined connecting plate 11 through the cutting groove 13. Both ends of the power shaft 32 extend to the outside of the inclined connecting plate 11 through the through socket 12. The surface of the torque motor 33 is fixedly connected to the surface of the inclined connecting plate 11. The bottom of the surface of the flat shell 39 is fixedly connected to the bottom of the inner wall of the inclined connecting plate 11. The bottom of the surface of the current alarm 36 is fixedly connected to the bottom of the inner wall of the inclined connecting plate 11.

[0036] The assembled stairs 2 and the connecting component 1 of the device are two independent structures before assembly. When a temporary staircase needs to be installed at a designated location for construction work, the required installation position of each connecting component 1 and the assembled stairs 2 is first calculated, and then the side of the connecting component 1 is fixed to the wall of the installation position. After each connecting component 1 is fixed, each assembled ladder 2 is installed at the position between the connecting components 1 on both sides, that is, the docking plugs 22 on both sides of each customized step plate 21 are inserted from top to bottom into the docking interface of the docking plug plate 15 through the relevant suspension device. At this time, the supporting component 4 below provides support for each section of the assembled stairs 2, and then the connection point of the assembled stairs 2 and the connecting component 1 is reinforced to obtain the assembled stair plate.

[0037] When the user climbs the stairs, he / she climbs on each customized step plate 21. When moving to the upper surface of the inclined connecting plate 11, the user stands on the left side of the upper surface of the friction belt 31 through the friction force between his / her feet and the upper surface of the friction belt 31. Then the torque motors 33 on both sides control the friction belt 31 to rotate clockwise by rotating the power shaft 32, thereby transporting the user above the friction belt 31 from bottom to top to save the user's physical strength. Even if the transfer component 3 of a certain section of the connecting component 1 fails and cannot be used, the user can walk along the upper surface of the friction belt 31 to the customized step plate 21 of the upper layer.

[0038] If the transfer component 3 collapses, the descending power shaft 32 and the load-bearing plate 34 will squeeze the flat shells 39 on both sides, causing the pressure-sensitive element 38 to be compressed and activating the current alarm 36 through the connecting plate 37, thereby preventing pedestrians from passing through the connecting component 1 here, thereby avoiding accidents before the safety hazard is resolved.

[0039] After the docking plug 22 is inserted into the hole of the docking plug plate 15, both sides of the upper surface of the bent support plate 41 are squeezed against the lower surface of the customized step plate 21. Since the vertical plug block 42 is fixed to the connecting socket 14, the inclined connecting plate 11 pulls the customized step plate 21 upward for support through the bent support plate 41, so the bent support plate 41 must remain fixed. When the bending support plate 41 becomes loose, the vertical plug block 42 cannot pull the bent support plate 41, so the bending support plate 41 will pull the side clamping plate 43 down through the side clamping plate 43, thereby causing the soft tube sleeve 44 to press down on the bottom of the inner wall of the inclined connecting plate 11. Since the soft tube sleeve 44 is a hose, the pressure rod 45 inside it will be squeezed, thereby reminding the maintenance personnel to perform maintenance work.

[0040] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: on the basis of embodiment 1, the impurity removing component 5 includes an arc-surface fixing bar 51, a parallel empty shell 52 is fixedly connected to one side of the surface of the arc-surface fixing bar 51, a pressure push rod 53 is slidably connected to the side of the inner wall of the parallel empty shell 52 away from the arc-surface fixing bar 51, and return springs 54 are provided on both sides of the surface of the pressure push rod 53, a blower 55 is fixedly connected to the side of the inner wall of the parallel empty shell 52 away from the pressure push rod 53, and an arc-shaped guide plate 56 is fixedly connected to the bottom of the surface of the blower 55.

[0041] There are two impurity removal components 5. The lower surface of the arc-surface fixing strip 51 is fixedly connected to the upper surface of the inclined connecting plate 11. The top of the blower 55 extends to the outside of the parallel empty shell 52. One end of the return spring 54 is fixedly connected to the inner wall of the parallel empty shell 52, and the other end of the return spring 54 is fixedly connected to the surface of the compressed push rod 53.

[0042] The stabilizing component 6 includes a side frame 61, an observer 64 is fixedly connected to the middle of the inner wall of the side frame 61, telescopic suction cups 63 are evenly arranged on the surface of the observer 64, adjustment telescopic rods 62 are fixedly connected to both sides of the inner wall of the side frame 61, and an instrument bar is fixedly connected to the top of the surface of the observer 64.

[0043] Both ends of the side frame 61 extend to the interior of the inclined connecting plate 11, one end of the telescopic rod 62 is adjusted to be fixedly connected to the inner wall of the side frame 61, and the other end of the telescopic rod 62 is adjusted to be plugged into the inner wall of the inclined connecting plate 11, and the side of the telescopic suction cup 63 away from the observer 64 is snap-fitted to the surface of the inclined connecting plate 11. There are two side frames 61, and the surfaces of the side frames 61 are fixedly connected to the wall.

[0044] If garbage impurities appear on the upper surface of the friction belt 31, the garbage will be squeezed against the compressed push rod 53 during the rotation of the friction belt 31, and then the compressed push rod 53 will be squeezed to the side close to the blower 55. At this time, the switch of the blower 55 is squeezed and started, and then air is sucked through the air inlet at the top, and jets are ejected outward through the arc-shaped guide plate 56 at the bottom, thereby blowing away the garbage blocked by the compressed push rod 53 and the arc-shaped fixing strip 51, and falling to both sides along the surface of the friction belt 31, thereby achieving a cleaning effect.

[0045] The inclined connecting plate 11 is fixed to the wall by the side frames 61 on both sides. After the two ends of the side frames 61 are installed into the interior of the inclined connecting plate 11, the side frames 61 can also slide a certain distance along the inner wall of the inclined connecting plate 11 and then be fixed to the inner wall of the inclined connecting plate 11 by adjusting the telescopic rod 62. Therefore, the gap between the side frames 61 and the inclined connecting plate 11 can be adjusted, so as to install additional equipment such as side-fixed steel bars, thereby reinforcing the device. The suction surface of the telescopic suction cup 63 is in contact with the inclined connecting plate 11. Once the fixed inclined connecting plate 11 shakes, the inclined connecting plate 11 will squeeze the observer 64 on the corresponding side through the telescopic suction cup 63, so that the reading of the observer 64 changes. The maintenance personnel can quickly judge whether the device is firmly installed by observing the reading of the observer 64.

[0046] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
