Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a device for finishing the surface of a corrugated roof. Background Technology

[0002] Large-scale buildings generally refer to multi-story or high-rise public buildings and hall-type buildings, such as stadiums, theaters, exhibition halls, and antique-style buildings related to folk culture. Many large-scale buildings feature wavy roofs, also known as undulating roofs. These are typically reinforced concrete structures. The construction involves erecting full-span scaffolding connected by fasteners, supporting the wavy bottom formwork of the roof, laying wavy reinforcing cages on the formwork, and then pouring the wavy concrete. While the wavy concrete reaches its predetermined strength, many workers manually finish the wavy concrete surface. Clearly, manual construction is inefficient, slow, and labor-intensive, and it's difficult to achieve high-quality results in terms of overall flatness and regularity of the wavy surface. Improvements are urgently needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a building wave roof finishing device that, compared with manual construction operations, has high construction efficiency, fast construction speed, low labor intensity for workers, and significantly improves the overall flatness and regularity of the concrete top surface of the wave roof.

[0004] The technical solution of this utility model is to provide a surface finishing device for a wavy roof, comprising a track composed of multiple I-beams extending along the length of the wavy roof and matching the undulating shape of the wavy roof. The top surface of the upper flange of each I-beam track is fixed with a toothed rack. The lower flange of each I-beam track located on both sides of the wavy roof is fixed to the top of multiple side support columns arranged along the length. The lower flange of each I-beam track located above the wavy roof is fixed to the top of multiple middle side support columns arranged along the length. The multiple I-beam tracks are parallel to each other, and the multiple toothed racks are parallel to each other.

[0005] The present invention provides a wave roof finishing device for buildings, which also includes at least two synchronously operating drive vehicles. The frame of each drive vehicle is rotatably fitted on the top surface of the upper flange plate of the I-beam track via at least one driven shaft. The gears of each drive vehicle are rotatably fitted on the two side plates of the frame. The teeth on the circumference of the gears mesh with the teeth on the top surface of the rack. A motor is also fixed on the frame, which drives the gears to rotate via a motor shaft and a transmission structure and drives the drive vehicle to move in a wave-like pattern along the I-beam track.

[0006] The present invention relates to a wave-shaped roof finishing device, which also includes a crossbeam fixed at both ends to the frames of two drive vehicles. Below the crossbeam is a scraper for finishing the concrete top surface of the wave-shaped roof. The crossbeam and the scraper are connected by multiple sets of vertical connecting components. Each set of vertical connecting components includes a scraper initial height adjustment structure and a scraper elastic clamping structure.

[0007] With the above structure, the new building wave roof finishing device has the following advantages:

[0008] Multiple side support columns and middle support columns support multiple I-beams that extend along the length of the roof and match the undulating shape of the corrugated roof concrete surface. The corrugated track surface is fixed with racks. The drive vehicle drives the scraper to move forward or backward along the corrugated track via gears that mesh with the racks. It automatically scrapes and smooths the corrugated roof concrete surface back and forth, and the desired effect can be achieved by repeating this process two or three times.

[0009] This utility model features multiple toothed I-beam tracks on both sides and above the concrete top surface of the roof. Its practicality is high. If the scraper is too wide, the resistance is too great, making it difficult to operate. This utility model, however, has multiple toothed I-beam tracks on the roof top, such as two toothed tracks, which relatively reduces the distance between the two I-beams, effectively controlling the width of the lateral operation. This ensures the scraper's force, strength, and flexibility in recovering the surface, guaranteeing excellent finishing results for the wavy roof concrete top surface.

[0010] Compared to manual construction, it has higher construction efficiency, faster construction speed, lower labor intensity for workers, and significantly improved overall flatness and regularity of the concrete top surface of the wavy roof, which can meet the higher quality requirements for plastering and leveling the concrete top surface of the wavy roof.

[0011] The finishing device has a simple structure, is easy to install and disassemble, and is firmly, stably and reliably supported. In particular, the circular gear and rack mesh with the track to go up or down the slope, driving the vehicle to move forward or backward in a wave-like pattern, driving the scraper to scrape and smooth the surface of the wavy roof concrete back and forth, thus finishing the surface. There is basically no "jumping" phenomenon, and its operation is smooth, flexible and reliable.

[0012] After the leveling and finishing of the concrete top surface of the wavy roof is completed, the device can be disassembled and lifted away manually with the help of a crane. The entire device can be reused multiple times, effectively saving on construction equipment and material costs.

[0013] Furthermore, the bottom end of each side support column is a first support base fixed to the floor slab or floor of the building. The main body of each side support column is a first steel pipe. The top end of each side support column is a first rectangular clamp with a first notch in the middle of the top plate. The first rectangular clamp is inserted into both sides of the lower flange plate from the end of the I-beam rail and slides to a predetermined position to support the I-beam rail located on the outside of the corrugated roof. The bottom center of the first rectangular clamp is fixed to a first steel sleeve. The top end of the first steel pipe of each side support column has a first lower internal thread, and the bottom end of each first steel sleeve has a first upper internal thread. The spiral direction of the first lower internal thread at the top end of the first steel pipe is opposite to the spiral direction of the first upper internal thread at the bottom end of the first steel sleeve. The side support column also includes a first threaded connecting column with a first regular hexagonal column in the middle section and first external threads at both ends. The first threaded connecting column is a threaded connecting column that is loosened by rotating in one direction and tightened by rotating in the other direction, and the spiral directions of the first external threads at the upper and lower ends are opposite. With the above structure, the support height of each side support column can be adjusted, and thus the overall height of the entire corrugated I-beam track on both sides of the corrugated roof can be adjusted together through multiple side support columns. Moreover, the support height of the side support column can be adjusted up or down simply by rotating the first threaded connecting column in either direction, which is very convenient. The installation or disassembly of each side support column also only requires rotating the first threaded connecting column in either direction, making installation and disassembly more convenient.

[0014] Furthermore, all or part of the multiple side support columns on each side are detachably connected to the full-span scaffolding supporting the bottom formwork of the corrugated roof. This structure makes the side support columns and I-beam tracks more secure, stable, and reliable, and also makes the leveling and finishing process—where the drive vehicle uses a scraper—more smooth, flexible, and reliable.

[0015] Furthermore, the bottom end of each intermediate side support column is a second support base fixed to the floor slab or floor of the building. The main body of each intermediate side support column is a second steel pipe. The top end of each intermediate side support column is a second rectangular clamp with a second notch in the middle of a second top plate. The second rectangular clamp is inserted into both sides of the lower flange plate from the end of the I-beam track located above the corrugated roof and slides to a predetermined position to support the I-beam track located above the corrugated roof. The bottom center of the second rectangular clamp is fixed to a second steel sleeve. The top end of the second steel pipe of each intermediate side support column has a second internal thread. Each second steel sleeve... The bottom end of the cylinder has a second upper internal thread, and the helical direction of the second lower internal thread at the top end of the second steel pipe is opposite to the helical direction of the second upper internal thread at the bottom end of the second steel sleeve. The middle side support column also includes a second threaded connecting column with a second regular hexagonal column in the middle section and second external threads at both ends. The second threaded connecting column is a threaded connecting column that is loosened by rotating in one direction and tightened by rotating in the other direction, and the helical directions of the second external threads at the upper and lower ends are opposite. The lower end of the second threaded connecting column passes through the corrugated bottom template, and there is a water-stop steel plate on the second threaded connecting column between the corrugated bottom template and the second regular hexagonal column. With the above structure, before the roof reinforced concrete is poured, the support height of each intermediate side support column can be adjusted. This allows multiple intermediate side support columns to work together to adjust the overall height of the entire corrugated I-beam track above the corrugated roof. In particular, because the bottom of the intermediate side support columns is supported on the floor slab or floor and passes through the bottom formwork (e.g., through holes), it avoids the instability and instability of the I-beam track that would occur if the intermediate side support columns were supported on the roof's reinforcing cage and the equipment was operating to perform surface finishing and leveling operations before the roof concrete was completely dry. This would negatively impact the final quality of the roof concrete. Furthermore, the support height of the intermediate side support column can be adjusted by simply rotating the first threaded connecting column in either direction, making adjustment very convenient. Installing each intermediate side support column also only requires rotating the second threaded connecting column in the opposite direction, further simplifying installation. It is not difficult to understand that during dismantling, the top and bottom surfaces of the reinforced concrete of each intermediate side support column are cut, and the cut surfaces are then manually ground and repaired. The dismantling is still simple and feasible, and the other parts that are cut off can be lifted away for reuse. The remaining parts left in the corrugated roof concrete after cutting can enhance the overall strength of the roof reinforced concrete.

[0016] Furthermore, the frame of each drive vehicle is a rectangular frame that can be inserted from the end of the I-beam rail and has a third notch in the middle of the base plate. The third notch is a notch for accommodating the web plate of the I-beam rail. The motor is vertically fixed to the top plate of the rectangular frame. The motor shaft passes through the top plate of the rectangular frame and a worm gear is coaxially fixed at its free end. The worm gear meshes with a worm, and the worm is coaxial with a gear. The small diameter of the middle section of the driven shaft is located above the rack. The large diameter rollers at both ends of the driven shaft roll and engage with the top surface of the upper flange plate of the I-beam rail on both sides of the rack. The two ends of the driven shaft rotate and engage with the two vertical plates of the rectangular frame. Each drive vehicle also includes a centering limiting structure that keeps the drive vehicle always in the center position of the I-beam rail. With the above structure, the circular gear and rack mesh more effectively, allowing the vehicle to climb or descend the track, further preventing "jumping" and ensuring the overall flatness and regularity of the high-wave-shaped undulating roof concrete surface. This further meets the high quality requirements of the wavy roof surface and makes the vehicle run more smoothly, flexibly, and reliably.

[0017] Furthermore, the centering limiting structure that ensures the drive vehicle remains centered within the width of the I-beam track consists of one or more pairs of centering locking posts fixed to the two vertical plates of the rectangular frame. One end face of each centering locking post slides into a vertical surface of the I-beam web to keep the drive vehicle centered within the width of the I-beam track. This structure is simple and reliable, further ensuring a smoother, more flexible, and reliable operation of the drive vehicle.

[0018] Furthermore, there can be multiple driven shafts, all on the same horizontal plane. This structure further ensures a smoother, more flexible, and more reliable operation of the drive vehicle, which automatically scrapes and smooths the surface along the wavy roof.

[0019] Furthermore, the crossbeam can be an angle steel, with both ends of the angle steel welded and fixed to the top surface of the inner end of the drive vehicle frame; the structure of each set of vertical connecting components is as follows: multiple third steel sleeves are welded and fixed to the outer side of the vertical plate of the angle steel, and multiple fourth steel sleeves are welded and fixed to the outer side of the scraper, which are coaxial with the third steel sleeves and correspond one-to-one. The third steel sleeve has a third internal thread that passes through both ends, and the fourth steel sleeve has a through hole that passes through both ends. The upper end of a connecting vertical rod is a third external thread that screws into the third internal thread and is used to adjust the initial height position of the scraper. The lower end of the connecting vertical rod is a smooth rod that movably fits into the through hole of the fourth steel sleeve. A compression spring for elastically pressing the scraper is fitted on the connecting vertical rod between the third steel sleeve and the fourth steel sleeve. The two ends of the compression spring abut against the third steel sleeve and the fourth steel sleeve, respectively. The bottom end of the connecting vertical rod has a fourth external thread, and a nut for axially limiting the bottom end of the connecting vertical rod is screwed onto the fourth external thread. With the above structure, the rigid connection between the two drive vehicles is more robust and reliable, the synchronization is better, the consistency of the scraper along the width of the roof is better, the adjustment of the initial height position of the scraper is more convenient and accurate, and multiple springs can keep the scraper at the predetermined scraping height and in close contact with the roof. Moreover, when encountering individual bulges or protrusions, the scraper can have some upward spring space so that it can be finished by two or three reciprocating strokes to finally achieve a high degree of flatness and regularity of the overall concrete top surface of the wavy roof, further meeting the high quality requirements for finishing the concrete top surface of the wavy roof.

[0037] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions of specific embodiments are intended to aid in understanding this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various specific embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown.

[0039] The wavy roof 11 of large buildings in the prior art, also known as the roof with a wave-like slope, such as the concrete top surface 111 with an angle of 45° between the upslope 1111 and the downslope 1112. Figure 1 The intersection of the upper slope 1111 and the lower slope 1112 of the concrete top surface of the corrugated roof 11 shown in the figure is an obtuse angle, i.e., a straight line. However, in actual construction, the intersection of the upper slope 1111 and the lower slope 1112 of the concrete top surface of the corrugated roof 11 can be a curved transition. Generally, when pouring the reinforced concrete of the corrugated roof 11, a full-span scaffold 12 connected by couplers can be erected. The scaffold 12 supports the corrugated bottom formwork 13 of the roof. A corrugated steel cage is laid on the corrugated bottom formwork 13, and then the concrete of the corrugated roof 11 is poured.

[0040] During the process of the corrugated roof 11 concrete reaching the predetermined strength, the corrugated roof finishing device of this utility model can be used to automatically carry out the finishing construction of the top surface 111 of the corrugated roof 11 concrete, or the concrete surface finishing construction, after the power is manually started. Finishing can also be called leveling and smoothing.

[0041] A preferred embodiment of the building wave roof finishing device of this utility model includes multiple rods such as Figure 1The four I-beams extending along the length of the corrugated roof 11 and matching its undulating shape form a track. Each I-beam track 2 has a rack 24 with teeth 241 on its top surface fixed to the top of its upper flange plate 21. The lower flange plate 23 of each I-beam track 2 located on both sides of the corrugated roof 11 is fixed to the top of multiple side support columns 4 arranged along the length direction. The track is positioned above the corrugated roof 11 as shown in the image. Figure 1 The lower flange plate 23 of each of the two I-beam rails shown is fixed to the top of multiple intermediate side support columns 5 arranged along the length direction. The multiple I-beam rails 2 are parallel to each other, and the multiple racks 24 are parallel to each other.

[0042] This utility model of a corrugated roof finishing device also includes at least two synchronously operating drive vehicles 3. The frame of each drive vehicle 3 is rotatably fitted onto the top surface of the upper flange plate 21 of the I-beam track 2 via at least one driven shaft 32. The gears 33 of each drive vehicle 3 are rotatably fitted onto the two side plates 313 of the frame, such as a rectangular frame 31. The teeth 331 on the circumference of the gears mesh with the teeth 241 on the top surface of the rack. A motor 34 is also fixed to the frame, such as the rectangular frame 31, which drives the gears 33 to rotate via a motor shaft 341 and a transmission structure, thereby driving the drive vehicle 3 to move in a corrugated pattern along the I-beam track 2. The corrugated movement is as follows: Figure 1 The diagram shows movement from left to right forward or from right to left backward. It is easy to understand that the teeth are not shown in the diagram. The teeth 331 on the circumference of the gear can also be described as the circumferential surface with teeth 331; similarly, the teeth 241 on the top surface of the rack can also be described as the top surface with teeth 241.

[0043] A preferred embodiment of the wave roof finishing device of this utility model further includes a crossbeam, such as an angle steel 61, fixed at both ends to the frame of two drive vehicles 3, such as a rectangular frame 31. Below the crossbeam, such as the angle steel 61, there is a scraper 62 for finishing the concrete top surface 111 of the wave roof 11. The crossbeam, such as the angle steel 61, and the scraper 62 are connected by multiple sets of vertical connecting components 63. Each set of vertical connecting components 63 includes a scraper initial height adjustment structure and a scraper elastic pressing structure.

[0044] The bottom end of each side support column 4 is a first support base 42 fixed to the floor slab or floor 14 of the building. The main body of each side support column 4 is a first steel pipe 43. The top end of each side support column 4 is a first rectangular clamp 41 with a first notch 4111 in the middle of a first top plate 411. The first rectangular clamp 41 is inserted into both sides of the lower flange plate 23 through the first groove 412 and slides to a predetermined position to support the I-beam rail 2 located on the outside of the corrugated roof 11. The bottom center of the first rectangular clamp 41 is fixed to a first steel sleeve 44, such as by welding. Each side support column 4 has a first steel pipe 43. The top end of the first steel pipe 43 of the support column 4 has a first lower internal thread 431, and the bottom end of each first steel sleeve 44 has a first upper internal thread. The helical direction of the first lower internal thread 431 at the top end of the first steel pipe 43 is opposite to the helical direction of the first upper internal thread at the bottom end of the first steel sleeve 44. The side support column 4 also includes a first threaded connecting column 45 with a first regular hexagonal column 451 in the middle section and first external threads 452 at both ends. The first threaded connecting column 45 is a threaded connecting column that is loosened by rotating in one direction and tightened by rotating in the other direction, and the helical directions of the first external threads 452 at the upper and lower ends are opposite.

[0045] The multiple side support columns 4 on each side are all or partly detachably connected to the full-span scaffolding 12 that supports the bottom formwork 13 of the corrugated roof 11. If fasteners are used, both fixing and disassembly are convenient.

[0046] The bottom end of each intermediate side support column 5 is a second support base 52 fixed to the floor slab or floor 14 of the building. The main body of each intermediate side support column 5 is a second steel pipe 53. The top of each intermediate side support column 5 is a second rectangular clamp 51 with a second notch 5111 in the middle of a second top plate 511. The second rectangular clamp 51 is inserted into the sides of the lower flange plate 23 through the second groove 512 above the corrugated roof 11 and slides to a predetermined position to support the corrugated roof 11 above the corrugated roof 11. The bottom center of the second rectangular clamp 51 is fixed to a second steel sleeve 54. The top end of the second steel pipe 53 of each intermediate side support column 5 has a second internal thread 531. Each second steel sleeve... The bottom end of 54 has a second upper internal thread, and the helical direction of the second lower internal thread 531 at the top end of the second steel pipe 53 is opposite to the helical direction of the second upper internal thread at the bottom end of the second steel sleeve 54. The middle side support column 5 also includes a second threaded connecting column 55 with a second regular hexagonal column 551 in the middle section and second external threads 552 at both ends. The second threaded connecting column 55 is a threaded connecting column that is loosened by rotating in one direction and tightened by rotating in the other direction, and the helical directions of the second external threads 552 at the upper and lower ends are opposite. The lower end of the second threaded connecting column 55 passes through the through hole on the wavy bottom template 13. There is a water-stop steel plate 56 on the second threaded connecting column 55 between the wavy bottom template 13 and the second regular hexagonal column 551.

[0047] It is easy to understand that each row of side support columns 4 and each row of middle support columns 5 extending along the length direction can be distributed at equal intervals along the length direction. Moreover, in the multiple rows of side support columns 4 and middle support columns 5 distributed along the width direction, the multiple side support columns 4 and middle support columns 5 in each row are all on the same straight line.

[0048] Each drive vehicle 3 has a frame 31 that can be inserted into the end of the I-beam rail 2 and has a third notch 3111 in the middle of its base plate 311. The third notch 3111 is a notch for accommodating the web plate 22 of the I-beam rail 2. The motor 34 is vertically fixed to the top plate 312 of the rectangular frame 31. The transmission structure can be as follows: the motor shaft 341 passes through a through hole in the top plate 312 of the rectangular frame 31, and a worm gear 35 is coaxially fixed to the free end of the motor shaft 341. The worm gear 35 meshes with a worm 36. The worm 36 is coaxial with a gear 33. The other end away from the worm 36 is a circular smooth rod and a circular support end. The outer end of the worm 36 is also a circular support end. The worm 36, gear 33, two circular support ends, and circular smooth rod can be made into a whole. The circular support end can also be called a support shaft. The small diameter 321 of the driven shaft 32 is located above the rack 24 and does not contact the rack 24. The large diameter rollers 322 at both ends of the driven shaft 32 roll and engage with the top surface of the upper flange plate 21 of the I-beam rail 2 on both sides of the rack 24. The two ends of the driven shaft 32 rotate and engage with the two vertical plates, i.e., the side plates 313, of the rectangular frame 31. The circular support ends, or support shafts, at both ends rotate and engage with the shaft holes of the side plates 313. Each drive vehicle 3 may also include a centering limiting structure that keeps the drive vehicle 3 always in the center position of the I-beam rail 2.

[0049] The centering limiting structure that keeps the drive vehicle 3 always in the middle of the width of the I-beam track 2 can be as follows: one or more pairs of centering locking posts 37 are fixed and welded to the two vertical plates, i.e. the two side plates 313, of the rectangular frame 31. One end face 371 of each centering locking post 37 slides with one vertical face of the web plate 22 of the I-beam so that the drive vehicle 3 is always in the middle of the width of the I-beam track 2.

[0050] Gear 33 can also be called driving gear or drive gear. The top plate 312 of rectangular frame 31 can also be called the top plate of rectangular frame.

[0051] It is not difficult to understand that the centering limit structure that keeps the drive vehicle always in the middle of the width of the I-beam track can also be a pair or more pairs of rollers installed on the two vertical plates of the rectangular frame and whose rolling surfaces are in vertical rolling cooperation with the web of the I-beam.

[0052] like Figure 6 As shown, the driven shaft 32 can be multiple, such as two, and multiple driven shafts 32 can be on the same horizontal plane. This results in better anti-jumping, smoother, and more flexible operation. Figure 6 As shown, the centering locking post 37 can be in multiple pairs, such as two pairs. The two pairs of centering locking posts 37 can be on the same horizontal plane, which improves the centering and limiting effect.

[0053] The crossbeam can be made of angle steel 61, and both ends of the angle steel 61 can be welded and fixed to the front end of the drive vehicle frame 3, such as... Figure 1 The top right end of the top plate 312 of the rectangular frame 31 shown. The structure of each set of vertical connecting components 63 can be as follows: multiple third steel sleeves 631 are welded and fixed to the outer surface of the vertical plate of the angle steel 61, i.e., the angle steel vertical plate 611; multiple fourth steel sleeves 632, coaxial with the third steel sleeves 631 and corresponding one-to-one, are welded and fixed to the outer surface of the scraper 62; the third steel sleeves 631 have third internal threads 6311 penetrating both ends; the fourth steel sleeves 632 have light holes 6321 penetrating both ends; the upper end of a connecting vertical rod 633 is screwed with the third internal thread 6311 and used to adjust the initial height of the scraper 62. The third external thread 6331 is located at the position. The lower end of the connecting vertical rod 633 is a smooth rod 6332 that movably fits into the smooth hole 6321 of the fourth steel sleeve 632. A compression spring 634 for elastically pressing the scraper 62 is fitted on the connecting vertical rod 633 between the third steel sleeve 631 and the fourth steel sleeve 632. The two ends of the compression spring 634 abut against the third steel sleeve 631 and the fourth steel sleeve 632 respectively. The bottom end of the connecting vertical rod 633 has a fourth external thread, on which a nut 635 for axially limiting the bottom end of the connecting vertical rod 633 is screwed. It is easy to understand that the third steel sleeve 631 can be evenly distributed along the length of the connecting crossbeam, such as the angle steel 61, and the fourth steel sleeve 632, coaxial with the third steel sleeve 631, can be evenly distributed along the length of the scraper 62. The structure where the third external thread 6331 of the connecting vertical rod 633 engages with the third internal thread 6311 of the third steel sleeve 631 constitutes the initial height adjustment structure for the scraper. It is easy to understand that this structure can adjust both the initial height of the scraper 62 and its horizontality across the width of the corrugated roof 1. The aforementioned compression spring 634 engages with the connecting vertical rod 633, with both ends of the spring abutting against the third steel sleeve 631 and the fourth steel sleeve 632. The smooth rod 6332 of the connecting vertical rod 633 movably engages with the smooth hole 6321 of the fourth steel sleeve 632. The nut 635 axially limits the bottom end of the connecting vertical rod 633, thus forming an elastic clamping structure for the scraper. The scraper 62 can also be called a scraper blade.

[0054] It is not difficult to understand, such as Figure 1The uphill slope 1111 shown can be called the left slope, and the downhill slope 1112 can be called the right slope. The crossbeam can also be made of I-beams. The drive vehicle 3 can also be called a drive trolley, or a trolley, or a drive assembly. The motor 34 can also include a lower gearbox, and the motor shaft 341 can also be the output shaft of the gearbox. The terms I-beam and H-beam are interchangeable. The terms support and bearing are interchangeable. A support column can also be called a support rod. A threaded connection column is also called a double-ended bolt. The rectangular clamp, such as the first rectangular clamp 41 and the second rectangular clamp 51, is located at the midpoint of its bottom surface, that is, the midpoint of its length and the midpoint of its width, which can also be understood as the center of the bottom surface. The compression spring 634 is also called a support spring. The support base, such as the first support base 42 and the second support base 52, can be fixed to the floor slab or floor 14 using multiple screws. The floor slab or floor 14 can also be called a floor plate or base plate. "Both sides," "outer side," and "side side" all refer to the same thing.

[0055] It is easy to understand that this utility model may also include multiple sensors and a central controller such as an MCU. The motor 34, sensors, and other electrical components are all electrically connected to the central controller. In actual construction operations, the drive vehicle 3 generally needs to make 2-3 round trips to repeatedly finish the surface, in order to achieve high quality requirements.

[0056] like Figure 1 As shown, it is easy to understand that after the concrete top surface 111 of the wavy roof 11 between the two I-beam rails 2 is finished, a crane can be used to lift the crossbeam such as the angle steel 61 and the two drive vehicles 3. Then, the two drive vehicles 3 and the crossbeam are manually pulled out from the right end and lifted to the left end of the I-beam rail 2 with the rack 241 on the unfinished concrete top surface 11 of the wavy roof 11. The two drive vehicles are then manually inserted from the left end, and the finishing work is carried out.

In case of any inconsistency between the drawings and the text description, or between the drawings themselves, the text description shall prevail.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
