Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building construction, in particular to a finishing device for the top surface of a large-scale building corrugated roof concrete surface. Background Art
[0002] Large buildings generally refer to multi-story or high-rise public buildings and hall-type buildings, such as stadiums, theaters, exhibition halls, folk culture-themed antique buildings, etc. Many roofs of large buildings adopt wavy roofs, also known as wavy up-and-down slope roofs. Generally, they are reinforced concrete structures, such as setting up a full-height scaffolding connected by fasteners, the scaffolding supports the wavy bottom formwork of the roof, and a wavy steel cage is laid on the wavy bottom formwork. The wavy concrete of the roof is then poured. When the wavy concrete reaches the predetermined strength, many workers manually perform wavy concrete surface finishing construction on the concrete top surface of the wavy concrete roof. Obviously, manual construction operations are inefficient, slow, and labor-intensive. In addition, the overall flatness and regularity of the wavy undulating surface are difficult to meet high quality requirements, and improvements are urgently needed. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a finishing device for the concrete top surface of the corrugated roof of a large building, which has high construction efficiency, fast construction speed, low labor intensity for workers, and the overall flatness and regularity of the concrete top surface of the corrugated roof can meet high quality requirements.
[0004] The technical solution of the present invention is to provide a finishing device for the concrete top surface of a large-scale building corrugated roof, comprising a track composed of multiple I-beams extending along the length direction of the corrugated roof and matching the undulating shape of the corrugated roof. A rack with a toothed top surface is fixed to the top surface of the upper flange plate of each I-beam track. The lower flange plate of each I-beam track located on both sides of the corrugated roof is fixed to the top of multiple side support columns arranged along the length direction. The lower flange plate of each I-beam track located above the corrugated roof is fixed to the top of multiple middle side support columns arranged along the length direction. The multiple I-beam tracks are parallel to each other, and the multiple racks are parallel to each other.
[0005] The device for finishing the top surface of a large-scale building's wavy roof concrete roof of the present invention also includes at least two synchronously operating drive vehicles. The frame of each drive vehicle is rotationally engaged with 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 rotationally engaged with 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 racks. The frame is also fixed with a motor that drives the gears to rotate via a motor shaft and a transmission structure and drives the drive vehicles to move along the wavy shape of the I-beam track.
[0006] The device for flattening the top surface of a large-scale building corrugated roof concrete of the present invention also includes a first crossbeam whose two ends are respectively fixed to the front ends of the frames of two driving vehicles, and the first crossbeam is connected to a pressing roller for flattening the top surface of the corrugated roof concrete via a connecting arm;
[0007] The device for finishing the top surface of a large-scale building corrugated roof concrete of the present invention also includes a second crossbeam with two ends respectively fixed to the frames of two driving vehicles. A scraper for finishing the top surface of the corrugated roof concrete is provided below the second crossbeam. The second crossbeam and the scraper are connected via multiple groups of vertical connection components. Each group of vertical connection components includes a scraper initial height adjustment structure and a scraper elastic pressing structure.
[0008] After adopting the above structure, the surface finishing device for the top surface of the corrugated roof concrete of a large building of the present invention has the following advantages:
[0009] Multiple side support columns and middle support columns support multiple tracks composed of I-beams extending along the length of the roof and matching the undulating shape of the wavy roof concrete top surface. A rack is fixed on the surface of the wavy track. The driving car drives the scraper to move forward along the wavy track through the gear engaged with the rack. The driving car drives the pressure roller through the gear engaged with the rack to apply pressure and leveling over a large area first, and the scraper retracts the surface as a whole.
[0010] The finishing device of the present invention requires only one driving vehicle to move forward once, i.e., the top surface of the wavy roof concrete can be flattened and finished along the wavy shape at one time. The construction efficiency is high, the construction speed is fast, the labor intensity of the workers is low, and the overall flatness and regularity of the concrete top surface of the wavy roof are good, which can meet the high quality requirements of leveling and plastering or finishing the concrete top surface of the wavy roof.
[0011] The present invention is provided with multiple I-beam tracks with racks on both sides and above the top surface of the roof concrete, which is very practical. If the scraper is too wide, the resistance will be large and it will be difficult to operate in practice. The present invention is also provided with I-beam tracks and racks on the top surface of the roof, which relatively reduces the distance between the two I-beams, effectively controls the width of the horizontal operation, ensures the force, strength and flexibility of the scraper to finish the surface, and ensures the excellent finishing effect of the concrete top surface of the wavy roof.
[0012] The device has a simple structure and is easy to install and disassemble. It also has a firm, stable and reliable support. In particular, the circular gear meshes with the rack and moves up or down the track, driving the vehicle forward in a wave-like manner with basically no "jumping" phenomenon. Its operation is smooth, flexible and reliable.
[0013] After the leveling and finishing or finishing of the corrugated roof concrete top surface is completed, the device can be manually disassembled and lifted away with the help of a crane. The entire device can be reused many times, effectively saving the cost of construction equipment and construction materials.
[0014] Furthermore, the pressure rollers are coaxial, with their ends rotatably engaged with the lower ends of their respective connecting arms. The upper end of each connecting arm is secured to the first vertical plate of the first crossbeam via multiple pairs of bolts and nuts. The number of bolt holes exceeds the number of bolts, allowing for stepwise adjustment of the pressure roller height. The finishing device also includes one or more scrapers positioned behind the pressure rollers to remove concrete protruding from the gap between the two pressure rollers. Each scraper has a width greater than the axial width of the gap between the two pressure rollers. The scrapers are secured to the scraper, with their bottom surfaces aligned with the bottom surface of the scraper. With this structure, the multiple connecting arms provide the pressure rollers with rigid forward support and downward pressure, ensuring improved leveling. The scrapers remove concrete protruding from the gap between the two pressure rollers. The bottom surfaces of the scrapers are aligned with the bottom surface of the scraper, and the scrapers are secured, such as by welding, to the scraper. Since the scraper has a height adjustment mechanism, the scrapers also have a height adjustment mechanism. Since the pressure roller is leveled first rather than finished last, the accuracy requirement for height adjustment is not high. Therefore, the use of multi-hole stepped adjustment of the pressure roller height can not only further ensure that the connecting arm provides the pressure roller with forward rigid support force and downward rigid pressure, but also fully meet the needs of actual construction.
[0015] Furthermore, there are three pressure rollers and six connecting arms, with the lower ends of every two connecting arms rotatably supporting one pressure roller. With the above structure, the specific number of pressure rollers and connecting arms is used, which is a preferred embodiment. This ensures that the pressure rollers are provided with optimal forward rigid support force and downward rigid pressure at a reasonable material cost, further ensuring a better leveling effect of the pressure rollers.
[0016] Furthermore, the bottom end of each side support column is a first support seat fixed on the floor or ground of the building, the main body of each side support column is a first steel pipe, and the top end of each side support column is a first rectangular clamp with a first notch in the middle of a top plate. The first rectangular clamp is inserted into the two 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 wavy roof, and the middle of the bottom surface 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 regular hexagonal column in the middle section and a first threaded connecting column with first external threads at both ends. The first threaded connecting column is a threaded connecting column that is rotated in one direction to loosen and rotated in the other direction to tighten, and the spiral directions of the first external threads at the upper and lower ends are opposite. After adopting the above structure, each side support column can adjust its support height, and then the overall height of the entire wavy I-beam track located on both sides of the wavy roof can be adjusted together through multiple side support columns; and the support height of the side support column can be raised or lowered by only rotating the first threaded connection column forward or backward, which is very convenient to adjust. To install or remove each side support column, only the first threaded connection column needs to be rotated forward or backward, making installation and removal more convenient.
[0017] Furthermore, multiple side support columns on each side are fully or partially detachably connected to the full-height scaffolding supporting the corrugated roof base formwork. This structure ensures a more secure, stable, and reliable fixation of the side support columns and I-beam rails, and also makes the scraping and finishing process driven by the drive vehicle smoother, more flexible, and more reliable.
[0018] Furthermore, the bottom end of each intermediate side support column is a second support seat fixed to the floor 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 from the end of the I-beam track above the wavy roof into both sides of the lower flange plate and slides to a predetermined position to support the I-beam track above the wavy roof, the middle of the bottom surface 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 lower internal thread, and each second steel sleeve There is a second upper internal thread at the bottom end of the cylinder, and the spiral direction of the second lower internal thread at the top end of the second steel pipe is opposite to the spiral 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 rotated in one direction to loosen and rotated in the other direction to tighten, and the spiral 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 wavy bottom template, and there is a waterstop steel plate on the second threaded connecting column between the wavy bottom template and the second regular hexagonal column. After adopting the above structure, before pouring the reinforced concrete of the roof, the middle side support column can adjust the support height of each middle side support column, and then adjust the overall height of the entire wavy I-beam track located above the wavy roof through multiple middle side support columns; in particular, because the bottom end of the middle side support column is supported on the floor or the floor and passes through the bottom formwork, it avoids the negative effect of the middle side support column being supported on the steel cage of the roof and the device being operated to perform the concrete top surface finishing and leveling, i.e., finishing operations when the roof concrete is not completely dry, which will cause the I-beam track to be unstable and unstable and affect the final quality of the roof concrete. In addition, the support height of the middle side support column can be raised or lowered by only rotating the first threaded connection column forward and backward, and the adjustment is very convenient. To install each middle side support column, only the second threaded connection column needs to be rotated forward, making the installation more convenient. It is not difficult to understand that during dismantling, the top and bottom surfaces of the reinforced concrete of each middle side support column are cut, and then the surface of the cut parts are manually polished and trimmed. The dismantling is still simple and feasible, and the other cut parts can be lifted away for reuse. The residual parts left in the wavy roof concrete after cutting can enhance the overall strength of the roof reinforced concrete.
[0019] Furthermore, the frame of each driving 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 bottom plate, and the third notch is a notch for accommodating the web of the I-beam rail; the motor is vertically fixed on 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 to the free end, the worm gear is engaged with a worm, and the worm gear is coaxial with the gear; the middle section of the driven shaft has a small diameter located above the rack, and the large diameter rollers at both ends of the driven shaft are rollingly engaged with the top surface of the upper flange plate of the I-beam rail on both sides of the rack, and the two ends of the driven shaft are rotatably engaged with the two vertical plates of the rectangular frame; each driving vehicle also includes a centering limit structure that ensures that the driving vehicle is always located in the center position of the I-beam rail. After adopting the above structure, the meshing ability of the circular gear and the rack is stronger when climbing or descending with the track, which further prevents the "jumping" phenomenon and further ensures the overall flatness and regularity of the high wavy roof concrete top surface, further meeting the high quality requirements of the wavy roof surface; and makes the operation of the drive vehicle more stable, flexible and reliable.
[0020] Furthermore, the centering limit structure that ensures the driving vehicle is always positioned in the middle of the I-beam track width comprises one or more pairs of centering retaining posts fixed to the two vertical plates of the rectangular frame. One end face of each centering retaining post slidably engages with a vertical surface of the I-beam web to ensure that the driving vehicle is always positioned in the middle of the I-beam track width. The centering limit structure adopts this specific structure, which is relatively simple and easy to install, and further ensures the smoother, more flexible, and reliable operation of the driving vehicle.
[0021] Furthermore, the driven shafts are multiple and are on the same horizontal plane. With the above structure, the driving vehicle drives the scraper to automatically scrape and smooth the wavy roof back and forth, thus achieving a smoother, more flexible and more reliable operation.
[0022] The locking mechanism is configured to lock the locking cam of the locking cam, and the locking cam has a lockhole that is formed on the locking cam face, and a lockhole that is formed on the locking cam face, and a lockhole that is formed on the locking cam face, and a lockhole that is formed on the locking cam face. After adopting the above structure, the rigid connection of the two drive vehicles is stronger and more reliable, the synchronization is better, the consistency of the scraper along the width direction of the roof is better, the adjustment of the initial height position of the scraper is more convenient and more accurate, and multiple springs can enable the scraper to always maintain a predetermined scraping height and fit the roof. Moreover, when encountering individual bulges and protrusions, the scraper can have a certain upward rebound space so that after two or three reciprocating surface finishing, the overall high flatness and high regularity of the wavy roof concrete top surface can be finally achieved, further meeting the high quality requirements of the wavy roof concrete top surface finishing.

[0047] The following is a further description of specific embodiments of the present invention with reference to the accompanying drawings. It should be noted that the description of these specific embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. Furthermore, the technical features involved in the various specific embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0048] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 shown.
[0049] The wavy roof 11 of a large building in the prior art is also called a roof with a wave-shaped slope. For example, the angle between the upslope 1111 and the downslope 1112 of the concrete top surface 111 can be 45°. Figure 1 The intersection of the upslope 1111 and downslope 1112 of the concrete top surface of the wavy roof 11 is shown as an obtuse angle, i.e., a straight line. However, in actual construction, the intersection of the upslope 1111 and downslope 1112 of the wavy roof 111 can be a curved transition. Generally, when pouring the reinforced concrete of the wavy roof 11, a full-height scaffolding 12 connected by fasteners is erected. The scaffolding 12 supports the wavy bottom formwork 13 of the roof. A wavy steel cage is laid on the wavy bottom formwork 13, and then the concrete of the wavy roof 11 is poured.
[0050] When the concrete of the corrugated roof 11 reaches a predetermined strength, the finishing device for the top surface of the corrugated roof concrete of a large building of the present invention is used. After the power is manually started, the finishing construction of the top surface 111 of the corrugated roof 11 or the concrete surface can be automatically performed. Finishing can also be called leveling and plastering.

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 rotated in one direction to loosen and rotated in the other direction to tighten, and the spiral 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 wavy bottom template 13, and there is a waterstop steel plate 56 on the second threaded connecting column 55 between the wavy bottom template 13 and the second regular hexagonal column 551.
[0064] It is easy to understand that each row of side support columns 4 and each row of middle side support columns 5 extending in the length direction can be equally spaced along the length direction. Moreover, in the multiple rows of side support columns 4 and middle side support columns 5 distributed in the width direction, the multiple side support columns 4 and middle side support columns 5 in each row are all on the same straight line.
[0065] The frame of each driving vehicle 3 can be a rectangular frame 31 that can be inserted from the end of the I-beam rail 2 and has a third notch 3111 in the middle of the bottom plate 311. The third notch 3111 is a notch that accommodates the web 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 the gear 33. The other end away from the worm 36 is a circular polished rod and a circular support end. The outer end of the worm 36 is also a circular support end. The worm 36, the gear 33, the two circular support ends, and the circular polished rod can be made into a single unit. The circular support end can also be called a support shaft. The middle section (smaller diameter) 321 of the driven shaft 32 is positioned above the rack 24, meaning it does not contact the rack 24. The large-diameter rollers 322 at each end of the driven shaft 32 rollably engage the top surfaces of the upper flange plates 21 of the I-beam track 2, located on either side of the rack 24. The ends of the driven shaft 32 rotatably engage the two vertical plates (i.e., side plates 313) of the rectangular frame 31. The circular support ends, or support shafts, at each end rotatably engage within the axial holes of the side plates 313. Each drive vehicle 3 also includes a centering stop structure that ensures the vehicle 3 is always centered within the I-beam track 2.
[0066] The centering and limiting structure that ensures the driving vehicle 3 is always positioned in the middle of the width of the I-beam track 2 can be: One or more pairs of centering retaining posts 37 are fixed, for example, welded, to the two vertical plates 313 of the rectangular frame 31. One end face 371 of each centering retaining post 37 slidably engages a vertical surface of the I-beam web 22 to maintain the driving vehicle 3 in the center of the I-beam track 2. The gear 33 can also be called a driving gear or a drive gear. The top plate 312 of the rectangular frame 31 can also be called the rectangular frame top plate.
[0067] It is not difficult to understand that the centering limit structure that keeps the driving vehicle always in the center 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 with the rolling surfaces cooperating with the I-beam web in vertical rolling motion.
[0068] like Figure 6 As shown, the driven shaft 32 can be multiple, such as two, and the multiple driven shafts 32 can be on the same horizontal plane. Its technical effects of preventing "jumping" and running smoothly and flexibly are better. Figure 6 As shown, the centering locking posts 37 can be multiple pairs, such as two pairs, and the two pairs of centering locking posts 37 can be on the same horizontal plane, and the technical effect of centering limiting is better.
[0069] The two ends of the second cross beam 61 can be welded and fixed to the front end of the frame of the driving vehicle 3. Figure 4The right end top surface of the top plate 312 of the rectangular frame 31 is shown in the figure. The structure of each set of vertical connection components 63 can be as follows: a plurality of third steel sleeves 631 are welded and fixed on the outer side of the second vertical plate 611 of the second crossbeam 61, that is, the angle steel vertical plate; a plurality of fourth steel sleeves 632 are welded and fixed on the outer side of the scraper 62, which are coaxial with the third steel sleeves 631 and correspond one to one; the third steel sleeve 631 has a third internal thread 6311 running through both ends; the fourth steel sleeve 632 has a light hole 6321 running through both ends; the upper end of a connecting vertical rod 633 is screwed with the third internal thread 6311 and is used to adjust the initial position of the scraper 62. The third external thread 6331 is positioned at a height, and the lower end of the connecting vertical rod 633 is a smooth rod 6332 that flexibly fits into the smooth hole 6321 of the fourth steel sleeve 632. A compression spring 634 is fitted onto the connecting vertical rod 633 between the third and fourth steel sleeves 631, 632, for elastically compressing the scraper 62. The ends of the compression spring 634 respectively abut against the third and fourth steel sleeves 631, 632. The bottom end of the connecting vertical rod 633 has a fourth external thread, onto which a nut 635 is screwed for axially limiting the bottom end of the connecting vertical rod 633. It is understood that the third steel sleeves 631 can be distributed equidistantly along the length of the connecting second crossbeam 61, and the fourth steel sleeves 632, coaxial with the third steel sleeve 631, can be distributed equidistantly along the length of the scraper 62. The screwed engagement of the third external thread 6331 of the connecting rod 633 with the third internal thread 6311 of the third steel sleeve 631 serves as the initial height adjustment mechanism for the scraper. This allows for adjustment of both the initial height of the scraper 62 and its levelness relative to the width of the wavy roof 1. The aforementioned compression spring 634 engages with the connecting rod 633, with both ends of the compression spring 634 contacting the third and fourth steel sleeves 631 and 632. The smooth rod 6332 of the connecting rod 633 flexibly engages with the smooth hole 6321 of the fourth steel sleeve 632, and the nut 635 axially limits the bottom end of the connecting rod 633, thereby forming the elastic compression mechanism for the scraper. The scraper 62 may also be referred to as a scraper plate.
[0070] It is not difficult to understand, such as Figure 11The uphill slope 1111 shown in the figure can be called the left slope, and the downhill slope 1112 can be called the right slope. The connecting arm can also be called a fork arm. The crossbeam can also be made of I-beam. 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 used interchangeably. The terms support and support are used interchangeably. The support column can also be called a support rod. The threaded connection column is also called a stud bolt. The middle of the bottom surface of a rectangular clamp, such as the first rectangular clamp 41 and the second rectangular clamp 51, is the middle of the bottom surface's length and width, and can also be understood as the center of the bottom surface. The compression spring 634 is also called a support spring. Support bases, such as the first support base 42 and the second support base 52, can be fixed to the floor or floor 14 using multiple screws. The floor or floor 14 can also be called the floor or bottom plate. Two sides, outside, and side are synonymous.
[0071] It is easy to understand that the present invention may also include multiple sensors and a central controller such as an MCU, and the motor 34, sensors and other electrical components are all electrically connected to the central controller.
[0072] like Figure 11 As shown, it is not difficult to understand that after the finishing of the concrete top surface 111 of the wavy roof 11 between the two I-steel rails 2 is completed, the second crossbeam 61 and the two driving vehicles 3 can be lifted by a crane, and then the two driving vehicles 3 and the crossbeam are manually pulled out from the right end, and then lifted to the left end of the I-steel rail 2 with the rack 241 on the concrete top surface 11 of the wavy roof 11 that has not been constructed, and the two driving vehicles are manually inserted from the left end, and then the finishing construction is carried out.
