Description

Technical Field

[0001] This invention relates to the technical field of building engineering, specifically to an intelligent sensing and adjusting roof support method for a building garage. Background Technology

[0002] In the field of building construction, especially in the construction of high-rise building complexes, underground parking garages that connect the entire site are built within the high-rise building complexes. After the underground parking garages are built, loads need to be stacked, vehicles need to drive, or construction needs to be carried out on the top slab of the underground parking garage. Since the design load of the underground parking garage top slab often cannot meet the requirements of the construction load, it is easy to cause the garage to deform or crack. Therefore, construction workers often need to provide back support for the underground parking garage top slab.

[0003] Currently, the back-support method typically uses a support frame, which is generally a steel pipe fastener frame, a disc-lock frame, or a ring-lock frame, etc. The back-support is achieved by fully supporting the top of the support frame. However, the above-mentioned back-support method requires construction workers to move the support frame to the area below the underground garage roof slab by hoisting and transporting it. After moving it to the appropriate position, the construction workers need to fix the top and bottom of the support frame with bolts and nuts. The whole process is time-consuming and labor-intensive, the construction speed is slow, and the construction risk is high, posing certain safety hazards.

[0004] Therefore, to solve the above technical problems, Chinese patent document (publication number CN109812051A) discloses a garage roof support frame and its construction method. This frame is installed between the garage floor and roof slabs and includes several vertically arranged uprights, horizontally arranged crossbars, and steel beams perpendicular to the uprights and crossbars. The uprights, crossbars, and steel beams are detachably connected via connectors. Each upright has a U-shaped support at the top and a padding layer at the bottom. A joist is installed between the U-shaped support and the garage roof slab. The construction steps are: measurement and layout, laying the padding layer, erecting the uprights and crossbars, connecting the beam bottom and the roof support frame, installing the U-shaped support, laying the joist, and adjusting the height of the U-shaped support to a suitable position.

[0005] Although the above technical solutions can solve the existing technical problems, the following technical problems still exist in the use of the above garage roof support frame: Problem 1: The above technical solutions involve the following construction process for installing the roof support frame: measuring and setting out lines, laying the pad layer, erecting uprights and crossbars, connecting the bottom of the beam and the roof support frame, installing U-shaped supports, laying the groove joists, and adjusting the height of the U-shaped supports to a reasonable position. Although mechanical installation by hoisting is not required, construction personnel still need to follow the above construction process, which leads to a longer construction period, slower construction speed, and safety hazards still exist during construction.

[0006] Question 2: Based on Question 1 above, since the installation position of the top support frame in the above technical solution is determined by measurement and layout, during the stacking, driving, or construction of the garage roof, construction personnel need to periodically inspect whether the load on the garage roof meets the construction load requirements. When the load at a certain location on the garage roof does not meet the construction load requirements, construction personnel need to readjust the spacing between the uprights and crossbars in the support frame so that multiple uprights can jointly support that location, resulting in a prolonged cycle and wasted labor costs. Similarly, when adjusting the spacing between the uprights and crossbars in the support frame, repeated disassembly and installation are required, wasting manpower and resources, resulting in slow construction speed, inconvenience, poor construction effect, and uncontrollable overall stress system. Summary of the Invention

[0007] The present invention aims to provide an intelligent sensing and adjusting support method for garage roofs, which can intelligently sense the stress load state of the garage roof and, based on the stress load sensing information, intelligently adjust the support state to meet the stress load at various locations of the garage roof, reduce manpower and material costs, and improve construction speed.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] 1) An intelligent sensor-controlled adjustable roof support method for a building garage, comprising the following steps:

[0010] Step S1: According to the construction load requirements on the garage roof, the structural frame is moved between the garage roof and the bottom of the garage in a moving manner. The distribution points of the surface load borne by the garage roof correspond one-to-one with the positions of the pressure sensors preset on the structural frame. Each pressure sensor on the structural frame monitors the load value of the surface load in real time, so that the load of the surface load borne by the garage roof is transferred to the structural frame, and the surface load of the garage roof is converted into the line load of the structural frame.

[0011] Step S2: After the structural frame is moved, the movable bottom support unit that moves along the radial direction of the garage is fixed to the bottom of the garage, and the movable top return unit that moves along the radial direction of the garage is fixed to the lower surface of the garage roof, so that the structural frame is stable between the garage roof and the bottom of the garage, thus completing the bearing of the surface load of the garage roof.

[0012] Step S3: When the load value detected in real time by each pressure sensor in a certain area of ​​the garage roof is higher than the preset value in the microprocessor, it is determined that the load at the location of the pressure sensor on the garage roof exceeds the construction load requirement. The microprocessor then sends a command to the telescopic frame unit in the structural frame to activate the displacement frame part in the telescopic frame unit corresponding to each pressure sensor in the above area. This causes the displacement frame parts to move closer together and drive the connected movable top-return unit and movable bottom-support unit to move closer together synchronously. After the movable top-return unit and movable bottom-support unit move closer together, they work together to top the garage roof in the above area and meet the construction load.

[0013] The above-mentioned technical solution uses a mobile method to move the structural frame between the garage roof and the garage floor, thereby solving the technical problem in the existing technology that requires construction personnel to install it according to the above construction process, which leads to an extended construction period. The structural frame is directly fixed to the garage floor by a mobile support unit and fixed to the lower surface of the garage roof by a mobile top-mounting unit, so that the structural frame is stable between the garage roof and the garage floor, and completes the bearing of the surface load of the garage roof. The operation is simple and convenient, shortens the construction speed, and reduces safety hazards.

[0014] Meanwhile, after the structural frame is stabilized between the garage roof and the garage floor, the overall structure of the structural frame supports the garage roof. During the process of the structural frame supporting the garage roof, several pressure sensors are evenly distributed and in contact with the garage roof, and detect the load values ​​at various positions on the garage roof in real time. All pressure sensors send the real-time detected load values ​​to the microprocessor.

[0015] When the load values ​​detected in real time by various pressure sensors in a certain area of ​​the garage roof are higher than the preset values ​​in the microprocessor, it is determined that the load at the location of the pressure sensor on the garage roof exceeds the construction load requirements. The microprocessor then sends a command to the telescopic frame unit within the structural frame to activate the displacement frame section within the telescopic frame unit corresponding to each pressure sensor in the aforementioned area. This causes the displacement frame section to move closer together, which in turn drives the connected movable top-return unit and movable bottom-support unit to move closer together synchronously. After the movable top-return unit and movable bottom-support unit move closer together, they work together to top the garage roof in the aforementioned area and meet the construction load requirements. Therefore, this invention can intelligently sense the stress load state of the garage roof and, based on the stress load sensing information, intelligently adjust its own top-support state to meet the stress load at various locations on the garage roof, reducing manpower and material costs.

[0016] 2) According to the intelligent sensor-adjustable roof support method for a building garage described in 1), wherein:

[0017] In step S2, the movable support unit is configured to have a lower moving slide rail fixed to the bottom of the garage. The upper surface of the lower moving slide rail has several support steel pipes arranged along the axial direction of the garage, and each support steel pipe moves back and forth along the radial direction of the garage.

[0018] The upper moving slide rail includes an upper fixed plate fixed to the garage roof. The upper fixed plate is evenly distributed with several strip-shaped upper sliding bars along its garage axis. The positions of the upper sliding bars correspond one-to-one with the positions of the pressure sensors. The pressure sensors are located on the upper surface of the upper fixed plate facing the garage roof. Each upper sliding bar is embedded in the upper fixed plate. Each upper sliding bar has an upper sliding groove along its axial direction for the reciprocating movement of the return steel pipe.

[0019] The movable top-return unit is configured with an upper movable slide rail fixed to the top of the garage. The upper movable slide rail has several pressure sensors evenly distributed on the lower surface of the garage roof for detecting the load on the garage roof. The upper surface of the upper movable slide rail has several top-return steel pipes arranged along the axial direction of the garage. Each top-return steel pipe reciprocates along the radial direction of the garage. The lower movable slide rail includes a lower fixed plate fixed to the bottom of the roof. The lower fixed plate has several strip-shaped lower sliding bars evenly distributed along its garage axial direction. Each lower sliding bar is embedded in the lower fixed plate. Each lower sliding bar has a lower sliding groove along its axial direction for the reciprocating movement of the bottom support steel pipe.

[0020] The above-mentioned technical solution uses a movable support unit and a movable top unit to limit the height of the telescopic frame unit, allowing the telescopic frame unit to connect with the movable support unit and the movable top unit to provide top support for the garage roof, ensuring that the underground garage roof meets the construction load and reducing deformation of the underground garage roof. At the same time, the upper sliding rail of the movable top unit is fixed to the top of the garage to connect the top of the telescopic frame unit to the top of the garage, and the lower sliding rail of the movable support unit is fixed to the bottom of the garage to connect the bottom of the telescopic frame unit to the bottom of the garage.

[0021] 3) According to the intelligent sensor-adjustable roof support method for a building garage described in 1), wherein:

[0022] In step S3, the structural frame is configured to have a telescopic frame located between the movable support unit and the movable return unit. The top of the telescopic frame is connected to the bottom of the return steel pipe to form an integral structure, and the bottom of the telescopic frame is connected to the top of the support steel pipe to form an integral structure. The telescopic frame has a displacement frame that moves reciprocally along the radial direction of the garage with the return steel pipe and the support steel pipe. It also includes a microprocessor, and all pressure sensors and the displacement frame are electrically connected to the microprocessor.

[0023] After the installation and fixing of the mobile top-mounting unit, telescopic frame unit and mobile bottom support unit are completed, the overall structure of the telescopic frame unit is used to support the garage roof. During the process of the telescopic frame unit supporting the garage roof, several pressure sensors in the upper moving slide rail are evenly distributed and in contact with the garage roof, and detect the load value at each position of the garage roof in real time. All pressure sensors send the real-time detected load value to the microprocessor.

[0024] When the load values ​​detected in real time by various pressure sensors in a certain area of ​​the garage roof are higher than the preset values ​​in the microprocessor, it is determined that the load at the location of the pressure sensor on the garage roof exceeds the construction load requirements. The microprocessor then sends a command to the telescopic frame unit to activate the displacement frame corresponding to the displacement frame parts of each pressure sensor in that area. This causes the displacement frame parts to move closer together, and simultaneously causes the connected top and bottom support steel pipes to move closer together as well. After the top and bottom support steel pipes move closer together, they work together to support the garage roof in that area, thereby achieving the goal of jointly supporting the garage roof to meet the construction load. Therefore, this invention can intelligently sense the stress load state of the garage roof and, based on the stress load sensing information, intelligently adjust its own support state to meet the stress load at various locations on the garage roof, reducing manpower and material costs.

[0025] 4) An intelligent sensor-controlled adjustable roof support method for a building garage as described in 1), wherein:

[0026] The telescopic frame includes several parallel starting steel pipes evenly arranged along the height direction. Several parallel connecting steel pipes are evenly arranged between adjacent starting steel pipes along their axial direction. The axes of all connecting steel pipes are perpendicular to the axes of the starting steel pipes. The two ends of the connecting steel pipes are welded to the adjacent starting steel pipes to form a single-sided drive net. The top of the single-sided drive net is welded to the top return steel pipe, and the bottom of the single-sided drive net is welded to the bottom support steel pipe. The single-sided drive net serves as a support surface to drive the displacement frame to reciprocate along the radial direction of the garage.

[0027] The above-mentioned technical solution employs several parallel starting steel pipes evenly arranged along the height direction, combined with several parallel connecting steel pipes evenly distributed along their axial direction between adjacent starting steel pipes to form a vertical network. The two ends of each connecting steel pipe in the vertical network are welded to the adjacent starting steel pipes to form a single-sided driving network. Therefore, the single-sided driving network serves as a support surface to support the displacement frame, and the starting steel pipes drive the displacement frame to gradually move towards or away from the support surface along the radial direction of the garage. This achieves intelligent adjustment of its own support state to meet the load-bearing capacity of various positions on the garage roof, reducing manpower and material costs and increasing construction speed.

[0028] 5) A method for intelligent sensor-adjustable roof support for a building garage as described in 4), wherein:

[0029] The displacement frame includes several top support surfaces that are evenly distributed along the height of the garage and reciprocate in the radial direction. The position of each top support surface corresponds one-to-one with the position of the return steel pipe, so that the top of all the top support surfaces are welded to the return steel pipe. The position of each top support surface corresponds one-to-one with the position of the bottom support steel pipe, so that the bottom of all the top support surfaces are welded to the bottom support steel pipe.

[0030] In the above technical solution, a displacement frame is formed by several support surfaces evenly distributed along the height of the garage and reciprocating in the radial direction. The position of each support surface corresponds one-to-one with the position of the return steel pipe, and the top of all support surfaces is welded to the return steel pipe. At the same time, the position of each support surface corresponds one-to-one with the position of the bottom support steel pipe, and the bottom of all support surfaces is welded to the bottom support steel pipe. The return steel pipe is located on the upper surface of the upper moving slide rail and moves in the radial direction of the garage, while the bottom support steel pipe is located on the upper surface of the lower moving slide rail and also moves in the radial direction of the garage. Therefore, the return steel pipe and the bottom support steel pipe together form an integrated structure with the top and bottom of all support surfaces. When the return steel pipe and the bottom support steel pipe move in the radial direction of the garage, they drive all support surfaces to move closer or further away in the radial direction of the garage.

[0031] 6) A method for intelligent sensor-adjustable roof support for a building garage as described in 5), wherein:

[0032] Each support surface includes several movable steel pipes evenly distributed along the radial direction of the garage. All movable steel pipes are parallel to the starting steel pipe. Several retractable tubes are evenly distributed on both sides of the movable steel pipe along its axial direction. The ends of all retractable tubes on the same side of the movable steel pipe are rotatably connected to the adjacent movable steel pipe or the starting steel pipe. The starting steel pipe is provided with a drive component along its axial direction to jointly drive the retractable tubes to extend or retract.

[0033] The above technical solution uses several movable steel pipes evenly distributed along the radial direction of the garage to form the support surface of the displacement frame. The position of each support surface corresponds to the position of the starting steel pipe, and all movable steel pipes are parallel to the starting steel pipe. Several retractable pipes evenly distributed along the axial direction on both sides of the movable steel pipes connect adjacent movable steel pipes to form a telescopic horizontal surface. Based on the telescopic horizontal surface, a driving component is installed inside the starting steel pipe to drive all retractable pipes to extend or retract. All driving components simultaneously and synchronously activate all retractable pipes on the telescopic horizontal surface, so that all telescopic horizontal surfaces move together towards or away from the unidirectional driving network, thereby adjusting the overall support state to meet the load-bearing capacity of various positions on the garage roof and reducing manpower and material costs.

[0034] 7) An intelligent sensor-controlled adjustable roof support method for a building garage as described in 6), wherein:

[0035] The driving component includes a servo motor electrically connected to a microprocessor and a starting screw passing through the starting steel pipe. The servo motor is mounted on a fixed plate between the upper and lower moving slide rails. The servo motor has an output shaft extending toward the starting steel pipe. The free end of the output shaft is coaxially and fixedly connected to the starting screw. The starting screw has several starting bevel gears evenly distributed along its axial direction. The starting bevel gears near the output shaft of the starting screw are connected to a linkage that drives adjacent moving steel pipes to move closer or further apart. The position of each starting bevel gear arranged along the axial direction of the starting screw corresponds one-to-one with the position of the retraction tube, and each starting bevel gear is connected to the corresponding retraction tube through a transmission structure.

[0036] In the above technical solution, each starting steel pipe corresponds to a driving component, and a servo motor in the driving component corresponds to one starting steel pipe. The output shaft of the servo motor extending towards the starting steel pipe is coaxially and fixedly connected to the starting screw. The starting screw extends along the axis of the starting steel pipe, passes through the starting steel pipe, and is located inside the starting steel pipe. Several starting bevel gears are evenly distributed along the axis of the starting screw. The position of each starting bevel gear corresponds to the position of the retraction tube, and each starting bevel gear and the corresponding retraction tube are connected by a transmission structure. The starting bevel gears on the starting screw near the output shaft synchronously drive the adjacent moving steel pipes to move closer or further apart through a linkage mechanism. Under the action of the transmission structure, the starting bevel gears drive the retraction tubes to extend or retract, and synchronously drive the adjacent moving steel pipes to move closer or further apart, thereby adjusting the support state of the overall support device.

[0037] 8) An intelligent sensor-controlled adjustable roof support method for a building garage as described in 7), wherein:

[0038] The transmission structure includes a drive screw that passes through the movable steel pipe. Several transmission bevel gears are evenly distributed along the axial direction of the drive screw. Each transmission bevel gear is meshed with a rotating bevel gear. The rotating bevel gear is coaxially and fixedly connected to the retracting tube. The other end of the retracting tube is fixed to an adjacent movable steel pipe.

[0039] In the above technical solution, when the drive screw rotates, it synchronously drives all the transmission bevel gears to rotate. When the transmission bevel gears rotate, they drive the meshing rotating bevel gears to rotate. During the rotation of the rotating bevel gears, they drive the retracting tube to rotate. Since the retracting tube can extend or retract during the rotation, it can drive the adjacent moving steel pipes to move closer or further away.

[0040] 9) A method for intelligent sensor-adjustable roof support for a building garage as described in 8), wherein:

[0041] The retraction tube includes an embedded lead screw, the end of which is coaxially connected to the transmission bevel gear. A nut sleeve is fitted on the embedded lead screw along its axial direction. The end of the embedded lead screw has a locking block that limits the nut sleeve. A movable cylinder is fixed on the outer surface of the nut sleeve. The nut sleeve is located inside the movable cylinder and drives the movable cylinder to reciprocate along the axial direction. The end of the movable cylinder away from the embedded lead screw is fixed on the movable steel pipe.

[0042] The above technical solution uses a transmission bevel gear to drive the rotation of an embedded lead screw. During the rotation of the embedded lead screw, the nut sleeve fitted on the embedded lead screw moves along the axis of the embedded lead screw. As the nut sleeve moves along the axis of the embedded lead screw, it simultaneously drives the moving cylinder to reciprocate along the axis. When the nut sleeve moves to the position of the locking block along the axis of the embedded lead screw, the nut sleeve drives the moving cylinder to gradually move away from the embedded lead screw. At the same time, the locking block limits the movement of the nut sleeve to prevent it from disengaging from the embedded lead screw when moving along the axis of the embedded lead screw. The cooperation between the embedded lead screw and the nut sleeve allows the moving cylinder to gradually move away from the embedded lead screw, thus elongating the entire retractable tube. Conversely, when the moving cylinder gradually moves towards the embedded lead screw, it shortens the entire retractable tube.

[0043] 10) A method for intelligent sensing and adjusting the roof support of a building garage as described in 7), wherein:

[0044] The linkage includes a drive bevel gear fixed coaxially to the end of the drive screw. A linkage upper bevel gear and a linkage lower bevel gear are respectively meshed on both sides of the drive bevel gear. The linkage upper bevel gear and the linkage lower bevel gear are respectively coaxially connected to a telescopic tube extending toward and through the adjacent moving steel pipe. The other end of the telescopic tube is coaxially connected to the linkage upper bevel gear on the adjacent drive screw, or coaxially connected to the linkage lower bevel gear on the adjacent drive screw. The end of the telescopic tube near the start screw has a linkage bevel gear that meshes with the start bevel gear on the start screw.

[0045] In the above technical solution, the linkage component drives adjacent moving steel pipes to move closer or further apart, thereby enabling all moving steel pipes to jointly form a supporting surface and achieve dimensional changes such as elongation or retraction. Based on the load sensing information of the garage roof, it intelligently adjusts its own supporting state to meet the load of various positions on the garage roof, reducing manpower and material costs. To achieve the above technical effect, a drive screw is used that passes through the moving steel pipe and is located inside the moving steel pipe. All drive screws are parallel and correspond to the corresponding starting screw. At the same time, a drive bevel gear is coaxially fixed at the end of each drive screw. The rotation of the drive bevel gear drives the drive screw to rotate. The upper and lower bevel gears are respectively meshed on both sides of the drive bevel gear. The upper and lower bevel gears are coaxially fixed with telescopic tubes. The telescopic tube end near the starting screw meshes with the starting bevel gear on the starting screw.

[0046] Therefore, in actual use, guided by the starting screw, the starting screw rotates under the drive of the servo motor, synchronously driving all the starting bevel gears to rotate. The linkage bevel gear at the end of the telescopic tube near the starting screw rotates synchronously under the rotation of the starting bevel gear. While the linkage bevel gear drives the telescopic tube to rotate, the linkage lower bevel gear away from the linkage bevel gear also rotates synchronously. Since the linkage lower bevel gear meshes with the drive bevel gear, and the drive bevel gear is coaxially mounted on the drive screw, during the rotation of the linkage lower bevel gear, the drive bevel gear rotates and drives the drive screw to rotate, causing all the transmission bevel gears on the drive screw to rotate synchronously. The transmission bevel gear drives the retraction tube to rotate to achieve extension or retraction, bringing adjacent moving steel pipes closer or further apart. In the process of adjacent moving steel pipes moving closer or further apart, the telescopic tube will be extended or retracted, thereby achieving the overall adjustment of the roof support state to meet the load-bearing capacity of various positions on the garage roof and reduce manpower and material costs.

[0047] 11) A method for intelligent sensing and adjusting the roof support of a building garage as described in 10), wherein:

[0048] The end of the movable steel pipe is sealed with a sealing block, and a limiting groove is opened on the side of the sealing block facing the movable steel pipe. A ball bearing is fixed in the limiting groove, and the end of the drive screw is embedded in the ball bearing.

[0049] The above technical solution uses a blocking block to support the drive screw. The specific operation is as follows: the end of the moving steel pipe is blocked with the blocking block, and the blocking block is locked and fixed with the moving steel pipe. The limiting groove opened on the side of the blocking block facing the moving steel pipe is used to fix the drive screw. In order to enable the drive screw to rotate smoothly, the ball bearing fixed in the limiting groove is coaxially connected with the drive screw, so that the drive screw can rotate smoothly under the action of the ball bearing.

[0050] Compared with the prior art, the present invention also has the following technical effects:

[0051] This invention uses several evenly distributed pressure sensors to detect the load on the garage roof. When the real-time load value detected by each pressure sensor in a certain area of ​​the garage roof is higher than a preset value in the microprocessor, it is determined that the load at the location of that pressure sensor exceeds the construction load requirement. The microprocessor then sends a command to start all servo motors. Each servo motor drives a starting screw to rotate, which in turn drives a starting bevel gear and a drive bevel gear. The drive bevel gear, through a linkage bevel gear, drives a telescopic tube near the starting screw to rotate. During this telescopic rotation, it drives a lower linkage gear coaxial with the starting bevel gear to rotate. The rotation of the lower linkage gear drives the drive bevel gear to rotate, which in turn drives the drive screw to rotate. The drive screw, in turn, drives several evenly distributed pressure sensors along its axial direction. The rotation of the transmission bevel gear, along with the synchronous drive of the starting bevel gear, causes the retractable tubes coaxially connected to it to extend and retract, allowing each support surface to move closer or further apart along the radial direction of the garage. This alters the dimensions of the entire telescopic frame unit, enabling the top and bottom support steel pipes to move closer together and jointly support the garage roof in a specific area. This ensures that the garage roof can withstand construction loads. Therefore, this invention can intelligently sense the load state of the garage roof and, based on this load information, intelligently adjust its support status to meet the load requirements at various locations on the garage roof. This reduces manpower and material costs, shares some of the load generated by large vehicles, and mitigates risks such as floor cracking or loads exceeding design values, ensuring project construction safety.

[0059] See the example. Figure 1 As shown in this embodiment, an intelligent sensor-adjustable roof support method for a building garage includes the following steps:

[0060] Step S1: According to the construction load requirements on the garage roof, the structural frame is moved between the garage roof and the bottom of the garage in a moving manner. The distribution points of the surface load borne by the garage roof correspond one-to-one with the positions of the pressure sensors preset on the structural frame. Each pressure sensor on the structural frame monitors the load value of the surface load in real time, so that the load of the surface load borne by the garage roof is transferred to the structural frame, and the surface load of the garage roof is converted into the line load of the structural frame.

[0061] Step S2: After the structural frame is moved, the movable bottom support unit that moves along the radial direction of the garage is fixed to the bottom of the garage, and the movable top return unit that moves along the radial direction of the garage is fixed to the lower surface of the garage roof, so that the structural frame is stable between the garage roof and the bottom of the garage, thus completing the bearing of the surface load of the garage roof.

[0062] Step S3: When the load value detected in real time by each pressure sensor in a certain area of ​​the garage roof is higher than the preset value in the microprocessor, it is determined that the load at the location of the pressure sensor on the garage roof exceeds the construction load requirement. The microprocessor then sends a command to the telescopic frame unit in the structural frame to activate the displacement frame part in the telescopic frame unit corresponding to each pressure sensor in the above area. This causes the displacement frame parts to move closer together and drive the connected movable top-return unit and movable bottom-support unit to move closer together synchronously. After the movable top-return unit and movable bottom-support unit move closer together, they work together to top the garage roof in the above area and meet the construction load.

[0063] This embodiment moves the structural frame between the garage roof and the garage floor, thus solving the technical problem in the prior art where construction workers need to follow the above construction process for installation, which leads to a longer construction period. It directly fixes the frame to the garage floor using a movable support unit and fixes the frame to the lower surface of the garage roof, making the structural frame stable between the garage roof and the garage floor, thus bearing the surface load of the garage roof. The operation is simple and convenient, shortens the construction speed, and reduces safety hazards.

[0064] See Figure 2 and Figure 3 As shown, in step S1, the movable support unit is configured to have a lower moving slide rail fixed to the bottom of the garage. The upper surface of the lower moving slide rail has several support steel pipes 5 arranged along the axial direction of the garage, and each support steel pipe 5 reciprocates along the radial direction of the garage. (See also...) Figure 4 As shown, the lower sliding rail includes a lower fixed plate 4 fixed to the bottom of the roof. The lower fixed plate 4 is evenly distributed with several strip-shaped lower sliding bars 3 along its garage axis. Each lower sliding bar 3 is embedded in the lower fixed plate 4. Each lower sliding bar 3 has a lower sliding groove for the bottom supporting steel pipe 5 to move back and forth along its axial direction.

[0065] The movable top-mounting unit is configured to have an upper moving slide rail fixed to the top of the garage. The upper moving slide rail has several pressure sensors evenly distributed on the lower surface of the garage roof slab 11 for detecting the load on the garage roof slab 11. The upper surface of the upper moving slide rail has several top-mounting steel pipes arranged along the axial direction of the garage. Each top-mounting steel pipe moves back and forth along the radial direction of the garage.

[0066] In this embodiment, the upper sliding rail includes an upper fixed plate 12 fixed on the garage roof 11. The upper fixed plate 12 is evenly distributed with several strip-shaped upper sliding bars 13 along its garage axis. The positions of the upper sliding bars 13 correspond one-to-one with the positions of the pressure sensors. The pressure sensors are set on the upper surface of the upper fixed plate 12 facing the garage roof 11. Each upper sliding bar 13 is embedded in the upper fixed plate 12. Each upper sliding bar 13 has an upper sliding groove along its axial direction for the return steel pipe 14 to move back and forth.

[0067] In this embodiment, the telescopic frame unit is configured to have a telescopic frame located between the movable support unit and the movable top unit. The top of the telescopic frame is connected to the bottom of the top steel pipe 14 to form an integral structure. The bottom of the telescopic frame is connected to the top of the support steel pipe 5 to form an integral structure. The telescopic frame has a displacement frame that moves reciprocally along the radial direction of the garage with the top steel pipe 14 and the support steel pipe 5. It also includes a microprocessor. All pressure sensors and the displacement frame are electrically connected to the microprocessor.

[0068] In this embodiment, the movable support unit and the movable top-return unit limit the height of the telescopic frame unit, enabling the telescopic frame unit to connect with the movable support unit and the movable top-return unit to provide top-return support for the garage roof slab 11, ensuring that the underground garage roof slab 11 meets the construction load and reducing the phenomenon of deformation of the underground garage roof slab 11; at the same time, the upper moving slide rail of the movable top-return unit is fixed to the top of the garage to connect the top of the telescopic frame unit with the top of the garage, and the lower moving slide rail of the movable support unit is fixed to the bottom of the garage to connect the bottom of the telescopic frame unit with the bottom of the garage.

[0069] After the installation and fixing of the movable top-mounting unit, the telescopic frame unit and the movable bottom support unit are completed, the overall structure of the telescopic frame unit is used to support the garage roof slab 11. During the process of the telescopic frame unit supporting the garage roof slab 11, several pressure sensors in the upper moving slide rail are evenly distributed and in contact with the garage roof slab 11, and detect the load value at each position of the garage roof slab 11 in real time. All pressure sensors send the real-time detected load value to the microprocessor.

[0070] When the load value detected in real time by each pressure sensor in a certain area of ​​the garage roof slab 11 is higher than the preset value in the microprocessor, it is determined that the load at the location of the pressure sensor on the garage roof slab 11 exceeds the construction load requirement. The microprocessor then sends a command to the telescopic frame unit to activate the displacement frame corresponding to the displacement frame parts of each pressure sensor in a certain area. This causes the displacement frame parts to move closer together and drive the connected top-mounted steel pipe 14 and bottom-supported steel pipe 5 to move closer together synchronously. After the top-mounted steel pipe 14 and bottom-supported steel pipe 5 move closer together, they jointly support the garage roof slab 11 in a certain area, thereby achieving the goal of jointly supporting the garage roof slab 11 to meet the construction load. Therefore, this invention can intelligently sense the stress load state of the garage roof slab 11 and, based on the stress load sensing information of the garage roof slab 11, intelligently adjust its own support state to meet the stress load at various locations of the garage roof slab 11, reducing manpower and material costs.

[0071] More specifically, see Figure 2 As shown, in this embodiment, the telescopic frame includes several starting steel pipes 1 that are evenly arranged and parallel to each other along the height direction. Several connecting steel pipes 8 that are evenly arranged and parallel to each other are arranged between adjacent starting steel pipes 1 along their axial direction. The axes of all connecting steel pipes 8 are perpendicular to the axes of the starting steel pipes 1. The two ends of the connecting steel pipes 8 are welded to the adjacent starting steel pipes 1 to form a single-sided driving net. The top of the single-sided driving net is welded to the top return steel pipe 14, and the bottom of the single-sided driving net is welded to the bottom support steel pipe 5. The single-sided driving net is used as the support surface to drive the displacement frame to move back and forth along the radial direction of the garage.

[0072] In this embodiment, several starting steel pipes 1 are evenly arranged along the height direction and are parallel to each other. Combined with several connecting steel pipes 8 evenly distributed along their axial direction between adjacent starting steel pipes 1 and are parallel to each other, they form a vertical net. The two ends of each connecting steel pipe 8 in the vertical net are welded to the adjacent starting steel pipes 1 to form a single-sided driving net. Therefore, the single-sided driving net serves as a support surface to support the displacement frame and drives the displacement frame to gradually move towards or away from the support surface along the radial direction of the garage using the starting steel pipes 1. This achieves intelligent adjustment of its own support state to meet the load of each position of the garage roof slab 11, reduce manpower and material costs, and improve construction speed.

[0073] Meanwhile, in this embodiment, the displacement frame includes several top support surfaces that are evenly distributed along the height direction of the garage and reciprocate in the radial direction. The position of each top support surface corresponds one-to-one with the position of the return steel pipe 14, so that the top of all the top support surfaces are welded to the return steel pipe 14. The position of each top support surface corresponds one-to-one with the position of the bottom support steel pipe 5, so that the bottom of all the top support surfaces are welded to the bottom support steel pipe 5.

[0074] In this embodiment, a displacement frame is formed by several support surfaces evenly distributed along the height of the garage and reciprocating in the radial direction. The position of each support surface corresponds one-to-one with the position of the return steel pipe 14, and the top of all support surfaces is welded to the return steel pipe 14. At the same time, the position of each support surface corresponds one-to-one with the position of the bottom support steel pipe 5, and the bottom of all support surfaces is welded to the bottom support steel pipe 5. The return steel pipe 14 is located on the upper surface of the upper moving slide rail and moves in the radial direction of the garage. At the same time, the bottom support steel pipe 5 is located on the upper surface of the lower moving slide rail and also moves in the radial direction of the garage. Therefore, the return steel pipe 14 and the bottom support steel pipe 5 together form an integrated structure with the top and bottom of all support surfaces. When the return steel pipe 14 and the bottom support steel pipe 5 move in the radial direction of the garage, they drive all support surfaces to move closer or further away in the radial direction of the garage.

[0075] In addition, Figure 3 In this embodiment, each supporting surface includes several movable steel pipes evenly distributed along the radial direction of the garage. All movable steel pipes are parallel to the starting steel pipe 1. Several retractable retractable pipes are evenly distributed on both sides of the movable steel pipes along their axial direction. The ends of all retractable pipes located on the same side of the movable steel pipe are rotatably connected to the adjacent movable steel pipe or the starting steel pipe 1. The starting steel pipe 1 is provided with a driving component along its axial direction to jointly drive the retractable pipes to extend or retract.

[0076] In this embodiment, several movable steel pipes evenly distributed along the radial direction of the garage form the support surface of the displacement frame. The position of each support surface corresponds to the position of the starting steel pipe 1. At the same time, all movable steel pipes are parallel to the starting steel pipe 1. Several retractable pipes evenly distributed along the axial direction on both sides of the movable steel pipes connect adjacent movable steel pipes to form a telescopic horizontal surface. Based on the telescopic horizontal surface, the starting steel pipe 1 is equipped with a driving component that drives all retractable pipes to extend or retract. All driving components simultaneously and synchronously activate all retractable pipes on the telescopic horizontal surface, so that all telescopic horizontal surfaces move together toward or away from the unidirectional driving network direction, thereby adjusting the overall support state to meet the load-bearing capacity of each position of the garage roof slab 11 and reduce manpower and material costs.

[0077] See Figure 2 and Figure 3 As shown, in this embodiment, the driving component includes a servo motor 9 electrically connected to the microprocessor and a starting screw 2 passing through the starting steel pipe 1. The servo motor 9 is mounted on a fixed plate between the upper and lower moving slide rails. The servo motor 9 has an output shaft extending toward the starting steel pipe 1. The free end of the output shaft is coaxially and fixedly connected to the starting screw 2. Several starting bevel gears 7 are evenly distributed along the axial direction of the starting screw 2. The starting bevel gears 7 near the output shaft of the starting screw 2 are connected to a linkage that drives adjacent moving steel pipes to move closer or further apart. The position of each starting bevel gear 7 arranged along the axial direction of the starting screw 2 corresponds one-to-one with the position of the retraction tube, and each starting bevel gear 7 is connected to the corresponding retraction tube through a transmission structure.

[0078] In this embodiment, each starting steel pipe 1 corresponds to a driving component, with a servo motor 9 in the driving component corresponding to one starting steel pipe 1. The output shaft of the servo motor 9 extending towards the starting steel pipe 1 is coaxially and fixedly connected to the starting screw 2. The starting screw 2 extends along the axial direction of the starting steel pipe 1, passes through the starting steel pipe 1, and is located inside the starting steel pipe 1. Several starting bevel gears 7 are evenly distributed along the axial direction of the starting screw 2. The position of each starting bevel gear 7 corresponds to the position of the retraction tube, and each starting bevel gear 7 is connected to the corresponding retraction tube through a transmission structure. The starting bevel gears 7 on the starting screw 2 near the output shaft synchronously drive the adjacent moving steel pipes to move closer or further apart through a linkage mechanism. Under the action of the transmission structure, the starting bevel gears 7 drive the retraction tube to extend or retract, and synchronously drive the adjacent moving steel pipes to move closer or further apart, thereby adjusting the support state of the overall support device.

[0079] Meanwhile, the transmission structure includes a drive screw 23 that passes through the moving steel pipe. Several transmission bevel gears 6 are evenly distributed along the axial direction of the drive screw 23. Each transmission bevel gear 6 is meshed with a rotating bevel gear. The rotating bevel gear is coaxially and fixedly connected to the retracting tube. The other end of the retracting tube is fixed to the adjacent moving steel pipe.

[0080] In this embodiment, when the drive screw 23 rotates, it synchronously drives all the transmission bevel gears 6 to rotate. When the transmission bevel gears 6 rotate, they drive the rotating bevel gears that mesh with them to rotate. During the rotation of the rotating bevel gears, they drive the retractable tube to rotate. Since the retractable tube can extend or retract during the rotation, it can drive the adjacent moving steel pipes to move closer or further away.

[0081] In addition, in this embodiment, the retraction tube includes an embedded lead screw 15. The end of the embedded lead screw 15 is coaxially connected to the transmission bevel gear 6. A nut sleeve 16 is sleeved on the embedded lead screw 15 along its axial direction. The end of the embedded lead screw 15 has a locking block that limits the nut sleeve 16. A movable cylinder 17 is fixed on the outer surface of the nut sleeve 16. The nut sleeve 16 is located inside the movable cylinder 17 and drives the movable cylinder 17 to reciprocate along the axial direction. The end of the movable cylinder 17 away from the embedded lead screw 15 is fixed on the movable steel pipe.

[0082] In this embodiment, the rotation of the transmission bevel gear 6 drives the rotation of the embedded lead screw 15. During the rotation of the embedded lead screw 15, the nut sleeve 16 sleeved on the embedded lead screw 15 moves along the axial direction of the embedded lead screw 15. During the movement of the nut sleeve 16 along the axial direction of the embedded lead screw 15, the nut sleeve 16 synchronously drives the moving cylinder 17 to reciprocate along the axial direction. When the nut sleeve 16 moves to the position of the locking block along the axial direction of the embedded lead screw 15, the nut sleeve 16 drives the moving cylinder 17 to gradually move away from the embedded lead screw 15. At the same time, the locking block limits the movement position of the nut sleeve 16 to prevent the nut sleeve 16 from disengaging from the embedded lead screw 15 when moving along the axial direction of the embedded lead screw 15. The cooperation between the embedded lead screw 15 and the nut sleeve 16 enables the moving cylinder 17 to gradually move away from the embedded lead screw 15, thereby elongating the entire retraction tube. Conversely, when the moving cylinder 17 gradually moves towards the embedded lead screw 15, the entire retraction tube is shortened.

[0083] See Figure 5As shown, in this embodiment, the linkage includes a drive bevel gear 22 coaxially fixed to the end of the drive screw 23. The drive bevel gear 22 has a linkage upper bevel gear 21 and a linkage lower bevel gear 19 meshing on both sides. The linkage upper bevel gear 21 and the linkage lower bevel gear 19 are coaxially connected to a telescopic tube 10 extending toward and through the adjacent moving steel pipe. The other end of the telescopic tube 10 is coaxially connected to the linkage upper bevel gear 21 on the adjacent drive screw 23, or coaxially connected to the linkage lower bevel gear 19 on the adjacent drive screw 23. The end of the telescopic tube 10 near the start screw 2 has a linkage bevel gear that meshes with the start bevel gear 7 on the start screw 2.

[0084] In this embodiment, the linkage mechanism drives adjacent moving steel pipes to move closer or further apart, thereby enabling all moving steel pipes to form a support surface that can extend or retract in size. Based on the load sensing information of the garage roof slab 11, it intelligently adjusts its own support state to meet the load requirements of each position of the garage roof slab 11, reducing manpower and material costs. To achieve the above technical effect, a drive screw 23 is used to penetrate the moving steel pipe and is located inside the moving steel pipe. All drive screws 23 are parallel and correspond to the corresponding starting screw 2. At the same time, a drive bevel gear 22 is coaxially fixed at the end of each drive screw 23. The rotation of the drive bevel gear 22 drives the drive screw 23 to rotate. The upper bevel gear 21 and the lower bevel gear 19 are respectively meshed on both sides of the drive bevel gear 22. The upper bevel gear 21 and the lower bevel gear 19 are coaxially fixed with telescopic tubes 10. The telescopic tube 10 near the starting screw 2 is meshed with the starting bevel gear 7 on the starting screw 2.

[0085] Therefore, in actual use, guided by the starting screw 2, the starting screw 2 rotates under the drive of the servo motor 9, synchronously driving all the starting bevel gears 7 to rotate. Meanwhile, the linkage bevel gear at the end of the telescopic tube 10 near the starting screw 2 rotates synchronously under the rotation of the starting bevel gear 7. Simultaneously, as the linkage bevel gear drives the telescopic tube 10 to rotate, the linkage lower bevel gear 19, which is away from the linkage bevel gear on the telescopic tube 10, also rotates synchronously. Since the linkage lower bevel gear 19 meshes with the drive bevel gear 22, and the drive bevel gear 22 is coaxially mounted on the drive screw 23, therefore... Therefore, during the rotation of the linkage, the bevel gear 19 drives the bevel gear 22 to rotate and drives the drive screw 23 to rotate, so that all the transmission bevel gears 6 on the drive screw 23 rotate synchronously. The transmission bevel gears 6 drive the retraction tube to rotate to achieve extension or retraction, bringing adjacent moving steel pipes closer or further apart. In the process of adjacent moving steel pipes moving closer or further apart, the telescopic tube 10 will be driven to extend or retract, thereby realizing the overall adjustment of the roof support state to meet the load of each position of the garage roof slab 11 and reduce manpower and material costs.

[0086] Meanwhile, in this embodiment, the end of the moving steel pipe is sealed with a sealing block 24, and the sealing block 24 has a limiting groove on the side facing the moving steel pipe. A ball bearing is fixed in the limiting groove, and the end of the drive screw 23 is embedded in the ball bearing.

[0087] In this embodiment, the blocking block 24 is used to support the drive screw 23. The specific operation is as follows: the blocking block 24 blocks the end of the moving steel pipe, and the moving steel pipe locks and fixes the blocking block 24. The limiting groove opened on the side of the blocking block 24 facing the moving steel pipe is used to fix the drive screw 23. In order to enable the drive screw 23 to rotate smoothly, the ball bearing fixed in the limiting groove is coaxially connected with the drive screw 23, so that the drive screw 23 can rotate smoothly under the action of the ball bearing.

[0088] In this embodiment, several evenly distributed pressure sensors are used to detect the load on the garage roof slab 11. When the load value detected in real time by each pressure sensor in a certain area of ​​the garage roof slab 11 is higher than the preset value preset in the microprocessor, it is determined that the load at the location of the pressure sensor on the garage roof slab 11 exceeds the construction load requirement. The microprocessor then sends a command to all servo motors 9 to start. Each servo motor 9 drives the starting screw 2 to rotate. The starting screw 2 synchronously drives the starting bevel gear 7 and the drive bevel gear 22. The drive bevel gear 22 drives the telescopic tube 10 near the starting screw 2 to rotate through the linkage bevel gear. During this telescopic rotation, it drives the coaxial linkage lower gear to rotate. When the linkage lower gear rotates, it drives the drive bevel gear 22 to rotate. When the drive bevel gear 22 rotates, it drives the drive screw 23 to rotate. The drive screw 23 synchronously drives the evenly distributed pressure sensors along its axial direction. Several transmission bevel gears 6 rotate, and the transmission bevel gears 6 and the starting bevel gear 7 synchronously drive the retraction tube connected to them on the same axis to extend and retract, so that each supporting surface moves closer or further away from each other along the radial direction of the garage, thereby changing the size of the entire telescopic frame unit. This allows the top steel pipe 14 and the bottom steel pipe 5 to move closer together and jointly support the garage roof slab 11 in a certain area, thus achieving the goal of jointly supporting the garage roof slab 11 to meet the construction load. Therefore, this invention can intelligently sense the stress load state of the garage roof slab 11 and, based on the stress load sensing information of the garage roof slab 11, intelligently adjust its own supporting state to meet the stress load of each position of the garage roof slab 11, reduce manpower and material costs, share part of the load generated by large vehicles, reduce the risk of floor cracking or load exceeding the design value, and ensure the safety of project construction.
