Description

Technical Field

[0001] This invention relates to the field of aerial work platforms, and more particularly to a sliding variable cross-section column clamp. Background Technology

[0002] For example, Chinese Utility Model Patent Publication No. CN 214462406 U discloses a steel column high-altitude construction platform, which includes a clamp for detachable connection to a canopy steel column. At least four supporting beams are horizontally welded to the upper part of the clamp, and several supporting columns are obliquely welded to the lower part of the clamp. The free ends of each supporting column are welded to the supporting beams. An operating platform is fixedly mounted on the supporting beams, and the operating platform is composed of two detachably connected construction platforms with identical structures. This method uses the clamp as the load-bearing point of the construction platform to achieve the construction of the high-altitude platform. However, this clamp cannot be raised from a low position to a high position, and its height cannot be increased for columns with variable cross-sections. Summary of the Invention

[0003] The purpose of this invention is to provide a sliding variable cross-section column clamp that can install the distribution beam when the clamp is in a low position and raise the distribution beam to a high position, and can also be used to lift variable cross-section columns.

[0004] To achieve the above objectives, a sliding variable cross-section column clamp is employed, comprising: The upper clamp has a redundant space in the transverse direction that is wider than the variable cross-section column. The redundant space is located on the left and right sides of the variable cross-section column in the transverse direction. In the longitudinal direction, it is closely attached to the front and rear sides of the variable cross-section column. The width of the variable cross-section column gradually increases from bottom to top in the transverse direction, while the thickness in the longitudinal direction remains unchanged. It includes a top plate, a bottom plate, an inner wall, lugs, and ribs connecting the top plate, bottom plate, and inner wall. The inner wall has a transverse elongated hole. The lower clamp has the same structure as the upper clamp. A wedge assembly, placed in a redundant space, includes an outer wedge and an inner wedge. The inner side of the inner wedge is a wedge surface, matching the lateral slope of the variable cross-section column. The outer side of the inner wedge is a vertical gear tooth surface. The inner wedge is narrower at the top and wider at the bottom, while the outer wedge is wider at the top and narrower at the bottom. The inner side of the outer wedge is also a vertical gear tooth surface, and a gear meshes between the two vertical gear tooth surfaces. The gear is coaxially fixed to a drive shaft, which extends longitudinally into a transverse elongated hole and is connected to a reduction motor. The base of the reduction motor is slidably mounted on a longitudinal motor track on a base plate. Vertical slide bars are fixed on the same side of the outer and inner wedges adjacent to the vertical gear tooth surfaces. The vertical slide bars are slidably connected between two vertical rails. The vertical rails are fixed to a transverse slide bar, which is slidably connected in a transverse slide rail. The transverse slide rail is fixed to the inner side of the upper and lower clamps. The lifting hydraulic cylinder has its base end installed on the top plate of the lower clamp; its telescopic end is installed on the bottom plate of the upper clamp. Lug fastening assembly, which is mounted on the opposite lug.

[0005] With this structure, in the lifting phase, the sliding upper clamp is unlocked by the lug fastening assembly. After unlocking, the upper clamp is still supported by the lifting hydraulic cylinder on the unlocked lower clamp. Then, with the gear driven by the reduction motor rotating the gears, the inner wedge moves downward and the outer wedge moves upward. That is, the lower wide head of the inner wedge moves away from the upper wide head of the outer wedge, thus reducing the overall width of the wedge assembly within the upper clamp. Originally, the gap width between the wedge and the upper clamp and the variable cross-section column of the canopy was 0, but now the gap width increases, releasing more width margin for relative movement. At this time, the four vertical rails on the same side are fixed in relative position by one horizontal slide bar. In effect, the inner and outer wedges are fixed in relative position, keeping the gears engaged. The inner and outer wedges are hung on the horizontal slide rail by the horizontal slide bar. The transverse slide rail is fixed inside the upper clamp, and then the upper clamp is in place. The lifting hydraulic cylinder on the lower clamp is activated, pushing the upper clamp upward. The wedge block assembly follows and rises. During the rising process, due to the transverse elongated hole, the base of the reduction motor is slidably mounted on the longitudinal motor track on the base plate, allowing it to slide. Thus, after the inclined surface of the canopy variable cross-section column contacts the inner wedge block, the wedge block assembly can be pushed to move as a whole to the inner side of the upper clamp until it completely fills the width allowance for relatively long movement. The upper clamp is then tightened by the lug fastening assembly and re-fixed to the canopy variable cross-section column. After the upper clamp is tightened, the lower clamp is unlocked in the same way, the wedge block assembly of the lower clamp is slid to release the width allowance, and then the lower clamp is lifted by retracting the lifting hydraulic cylinder. Finally, the lug fastening assembly of the lower clamp is tightened to complete the locking. In this way, one lifting process is completed. The entire lifting process can be repeated multiple times to the end position, or a large-stroke lifting hydraulic cylinder can be used to lift it to the position in one go; the lug fastening assembly can be locked with high-strength bolts and nuts and washers.

[0006] As a further improvement of the present invention, the lug fastening assembly includes: a pin shaft passing through two opposing lugs, pin shaft heads installed at both ends of the pin shaft, and a locking cylinder passing through the two opposing lugs. The base end of the locking cylinder is installed on a rib plate. After the piston of the locking cylinder passes through the two opposing lugs, a locking head is installed and presses against the outside of the lugs. A spring is wrapped around the pin shaft. The spring is compressed and connected between the two opposing lugs.

[0007] When using such a lug fastening assembly, in the locked state, the locking cylinder drives the locking head to press the lug, at which time the spring is compressed. In the unlocked state, the locking head moves away from the lug, and the spring pushes the lug open.

[0008] As a further improvement of the present invention, a gear surface pad is provided between the outer wedge and the inner wedge. The gear surface pad can extend between two opposing vertical gear tooth surfaces and fit together. The gear surface pad is fixed on the longitudinal shaft, which is located above or below the drive shaft. A corresponding transverse elongated hole is also provided on the inner wall for the longitudinal shaft to pass through. The end of the longitudinal shaft is mounted on the transverse elongated hole, and one end of the longitudinal shaft is fixed on the upright plate. The upright plate is mounted on the telescopic end of the pad switching electric push rod. The base of the pad switching electric push rod is slidably mounted on the transverse electric push rod track, and the transverse electric push rod track is mounted on the base plate.

[0009] With this structure, the electric push rod for switching the pad block controls the lateral movement of the gear-face pad block via the drive plate and the longitudinal shaft. The pad block extends between the vertical tooth surfaces of the outer and inner wedges, ensuring stable force transmission between the clamp and the variable cross-section column of the canopy when the clamp is locked. After the gear has finished rotating, the gear-face pad block extends between the vertical tooth surfaces, securing the outer and inner wedges. Then, during the upward movement, it moves towards the inside of the clamp along with the outer and inner wedges, ensuring stable pressure transmission after the clamp is locked. When the clamp is unlocked, the gear-face pad block needs to exit between the vertical tooth surfaces to avoid obstructing gear rotation. The base of the electric push rod for switching the pad block is slidably mounted on the transverse electric push rod track and is equipped with corresponding transverse elongated holes for lateral movement, allowing it to move laterally along with the gear-face pad block during lateral movement.

[0010] As a further improvement of the present invention, two sets of wedge block assemblies are arranged side by side on the front and rear sides of the variable cross-section column; the two sets of wedge block assemblies on the same side are symmetrically arranged and located on both sides of two opposite lugs.

[0011] With this structure, the two sets of wedge components can make full use of the redundant space between the clamp and the variable cross-section column of the canopy, and expand the force application area.

[0012] As a further improvement of the present invention, the outer wedge surface of the outer wedge block is in contact with the inner side of the top plate, bottom plate and inner wall, and the inclined surface formed by the inner side of the top plate, bottom plate and inner wall maintains the same inclination as the outer wedge surface of the outer wedge block.

[0013] With this structure, the outer wedge can fit tightly against the inner side of the clamp, ensuring the area of ​​force distribution.

[0014] As a further improvement of the present invention, the outer wedge and the inner wedge include a wedge plate and trapezoidal ribs fixed on the wedge plate. Two vertical trapezoidal ribs are arranged side by side at intervals on one wedge plate. The opposing surfaces of the opposing trapezoidal ribs on the outer wedge and the inner wedge are vertical gear tooth surfaces, and gears mesh between the two opposing vertical gear tooth surfaces.

[0015] With this structure, the trapezoidal ribs ensure that after being fixedly connected to the outer and inner wedges, the two opposite sides of the trapezoidal ribs are vertical, and as vertical gear tooth surfaces, they can fully mesh with the gears.

[0016] As a further improvement of the present invention, the two sets of wedge block assemblies side by side share the same reduction motor, and the drive shafts of the two sets of wedge block assemblies are coaxially connected together; the reduction motor is installed on the base plate extending beyond the variable cross-section column on the front side of the upper clamp and the lower clamp; the two sets of wedge block assemblies side by side share a pad switching electric push rod, and the longitudinal axes of the two sets of wedge block assemblies are coaxially connected together through a longitudinal plate, which can pass through the rail groove of the transverse slide rail.

[0017] With this structure, a single pad switching electric push rod can drive the lateral translation of the gear surface pads of two sets of wedge block assemblies. With the geared motors each set on one side of the clamp, the thickness of the longitudinal plate is reduced, which will not damage the rail groove and can also ensure the stable connection of the longitudinal shaft. As a further improvement of the present invention, the cross-section of the vertical rail, the horizontal slide bar, and the rail groove is T-shaped.

[0018] With this structure, the T-shape, as the main cross-sectional form of the sliding pair type, can ensure stable sliding without slippage.

[0019] As a further improvement of the present invention, two vertical rails paired with one vertical slide bar together form a vertical track, and a limiting plate is fixed between adjacent vertical rails of the two vertical rails fixed on a horizontal slide bar, the limiting plate sliding through the longitudinal axis.

[0020] With this structure, the limiting plate can ensure the smooth transition of the gear face pad.

[0021] As a further improvement of the present invention, both ends of the drive shaft are mounted in a transverse elongated hole, one end of which is connected to a reduction motor, and the other end of which is connected to a limiting wheel, the limiting wheel being tightly attached to the outer side of the inner wall.

[0022] With this structure, the limit wheel can prevent slippage when the drive shaft rotates.

[0023] This invention can install the distribution beam when the clamp is in a low position and raise the distribution beam to a high position, and it can also be used to raise columns with variable cross-sections. Attached Figure Description

[0057] Example 1 like Figures 1-10 As shown, a sliding variable cross-section column clamp includes: The upper clamp 101 has a redundant space 102 in the transverse direction that is wider than the variable cross-section column. The redundant space 102 is located on the left and right sides of the variable cross-section column in the transverse direction. In the longitudinal direction, it is closely attached to the front and rear sides of the variable cross-section column. The width of the variable cross-section column gradually increases from bottom to top in the transverse direction, while the thickness in the longitudinal direction remains unchanged. It includes a top plate 1011, a bottom plate 1012, an inner wall 1013, a lug 1014, and a rib 1015 connecting the top plate 1011, the bottom plate 1012, and the inner wall 1013. The inner wall 1013 has a transverse elongated hole 1016. The lower clamp 103 has the same structure as the upper clamp 101; A wedge assembly 104, placed in redundant space 102, includes an outer wedge 1041 and an inner wedge 1042. The inner side of the inner wedge 1042 is a wedge surface, which matches the lateral slope of the variable cross-section column. The outer side of the inner wedge 1042 is a vertical gear tooth surface 1043. The inner wedge 1042 is narrower at the top and wider at the bottom, while the outer wedge 1041 is wider at the top and narrower at the bottom. The inner side of the outer wedge 1041 is also a vertical gear tooth surface 1043. A gear 1044 meshes between the two vertical gear tooth surfaces. The gear 1044 is coaxially fixed on a drive shaft 1045, which extends longitudinally into a transverse elongated hole 10. 16 is connected to the geared motor 1046, and the base of the geared motor 1046 is slidably mounted on the longitudinal motor track 1047 on the base plate 1012; the outer wedge block 1041 and the inner wedge block 1042 are each fixed with a vertical slide bar 1048 on the same side adjacent to the vertical gear tooth surface 1043; the vertical slide bar 1048 is slidably connected between two vertical rails 1049; the vertical rail 1049 is fixed on the transverse slide bar 10410, the transverse slide bar 10410 is slidably connected in the transverse slide rail 10411, and the transverse slide rail 10411 is fixed inside the upper clamp 101 and the lower clamp 103; The lifting hydraulic cylinder 105 has its base end installed on the top plate 1011 of the lower clamp 103; its telescopic end is installed under the bottom plate 1012 of the upper clamp 101. Lug fastening assembly 106 is mounted on the opposite lug 1014.

[0058] With this structure, in the lifting phase, the sliding upper clamp 101 is unlocked by the lug fastening assembly 106. After unlocking, the upper clamp 101 is still supported by the lifting hydraulic cylinder 105 on the unlocked lower clamp 103. Then, with the gear 1044 driven by the reduction motor 1046 rotating, the inner wedge 1042 moves downward and the outer wedge 1041 moves upward. That is, the lower wide head of the inner wedge 1042 moves away from the upper wide head of the outer wedge 1041, thus reducing the position of the wedge assembly on the upper clamp. The overall width of section 101, which was originally 0 in width with respect to the upper clamp and the variable cross-section column of the canopy, has now increased, meaning more width margin has been released for relative movement. At this point, the four vertical rails 1049 on the same side are fixed in relative position by one horizontal slide bar 10410. In effect, the inner wedge block 1042 and the outer wedge block 1041 are fixed in relative position, keeping the gear 1044 engaged. The inner wedge block 1042 and the outer wedge block 1041 are suspended from the horizontal slide rail 10410 via the horizontal slide bar 10410. On 411, the transverse slide rail 10411 is fixed to the inner side of the upper clamp 101. Then, the upper clamp 101 is in place, and the lifting hydraulic cylinder 105 on the lower clamp 103 is activated, starting to push the upper clamp 101 upward. The wedge block assembly 104 then rises accordingly. During the rising process, due to the transverse elongated hole 1016, the base of the reduction motor 1046 is slidably mounted on the longitudinal motor track 1047 on the base plate 1012, allowing it to slide. Thus, after the inclined surface of the variable cross-section column of the canopy contacts the inner wedge block 1042, the wedge block assembly 104 can be pushed. 04. Move the upper clamp 101 inwards until it completely fills the width allowance for relatively long-distance movement. Then, tighten the upper clamp 101 with the lug fastening assembly 106 and re-fix it to the variable cross-section column of the canopy. After tightening the upper clamp 101, unlock the lower clamp 103 in the same way, slide the wedge block assembly 104 of the lower clamp 103 to release the width allowance, and then lift the lower clamp 103 by retracting the lifting hydraulic cylinder 105. Finally, tighten the lug fastening assembly 106 of the lower clamp 103 to lock it in place. This completes one lifting process. The entire lifting process can be repeated multiple times to the end position, or the large-stroke lifting hydraulic cylinder 105 can be used to lift it to the position in one go. The lug fastening assembly 106 can be locked with high-strength bolts and nuts and washers.

[0059] like Figures 9-10 As shown, Figure 9 In the middle, the clamp is in the initial position, with the inner wedge 1042 and the outer wedge 1041 being wide-end to wide-end, making it the widest overall; in Figure 10 In the middle, the clamp is at the end position, and the inner wedge block 1042 and the outer wedge block 1041 are narrow head to narrow head, making it the narrowest part overall.

[0060] The distribution beam 200 is installed on the upper side of the upper clamp 101. After the distribution beam 200 is lifted, the canopy formwork system jacking and sliding platform 300 is installed on the distribution beam 200. Horizontal supports are connected between the distribution beams.

[0061] In this embodiment, the lug fastening assembly 106 includes: a pin 1061 passing through two opposing lugs 1014, pin heads 1062 installed at both ends of the pin 1061, and a locking cylinder 1063 passing through the two opposing lugs 1014. The base end of the locking cylinder 1063 is installed on the rib plate 1015. The piston 10631 of the locking cylinder 1063 passes through the two opposing lugs 1014 and is fitted with a locking head 10632 that presses against the outside of the lugs 1014. A spring 1064 is wrapped around the pin 1061. The spring 1064 is compressed and connected between the two opposing lugs 1014.

[0062] When such a lug fastening assembly 106 is used, in the locked state, the locking cylinder 1063 drives the locking head 10632 to press the lug 1014, at which time the spring 1064 is compressed. In the unlocked state, the locking head 10632 moves away from the lug 1014, and the spring 1064 pushes the lug 1014 away.

[0063] In this embodiment, a gear surface pad 10412 is further provided between the outer wedge block 1041 and the inner wedge block 1042. The gear surface pad 10412 can extend between two opposing vertical gear tooth surfaces 1043 and fit into them. The gear surface pad 10412 is fixed on the longitudinal shaft 10413, which is located above or below the drive shaft 1045. A corresponding transverse elongated hole 1016 is also provided on the inner wall 1013 for the longitudinal shaft. 10413 passes through, and the end of the longitudinal shaft 10413 is mounted on the transverse elongated hole 1016. One end of the longitudinal shaft 10413 is fixed on the upright plate 10414. The upright plate 10414 is mounted on the telescopic end of the pad switching electric push rod 10415. The base of the pad switching electric push rod 10415 is slidably mounted on the transverse electric push rod track 10416. The transverse electric push rod track 10416 is mounted on the base plate 1012.

[0064] With this structure, the electric push rod 10415 for switching the pad block drives the vertical shaft 10413 via the drive plate 10414 to control the lateral movement of the gear surface pad block 10412, which then extends between the vertical gear tooth surfaces 1043 of the outer wedge block 1041 and the inner wedge block 1042. This ensures stable force transmission between the clamp and the variable cross-section column of the canopy when the clamp is locked. After the gear 1044 has finished rotating, the gear surface pad block 10412 extends between the vertical gear tooth surfaces 1043, stabilizing the outer wedge block 1041 and the inner wedge block 1042. Then, during the upward movement, it moves towards the inside of the clamp along with the outer wedge block 1041 and the inner wedge block 1042, ensuring stable pressure transmission after the clamp is locked. When the clamp is unlocked, the gear surface pad block 10412 needs to exit between the vertical gear tooth surfaces 1043 to avoid obstructing the rotation of the gear 1044. The base of the pad switching electric push rod 10415 is slidably mounted on the transverse electric push rod track 10416 and is equipped with a corresponding transverse elongated hole 1016 for transverse movement, that is, when the gear surface pad 10412 moves laterally, it can move laterally together with the gear surface pad 10412.

[0065] In this embodiment, two sets of wedge block assemblies 104 are arranged side by side on the front and rear sides of the variable cross-section column; the two sets of wedge block assemblies 104 on the same side are symmetrically arranged and located on both sides of two opposing lugs 1014.

[0066] With this structure, the two sets of wedge components 104 can make full use of the redundant space 102 between the clamp and the variable cross-section column of the canopy, and expand the force application area.

[0067] In this embodiment, the outer wedge surface of the outer wedge block 1041 is in contact with the inner side of the top plate 1011, the bottom plate 1012 and the inner wall 1013, and the inclined surface formed by the inner side of the top plate 1011, the bottom plate 1012 and the inner wall 1013 maintains the same inclination as the outer wedge surface of the outer wedge block 1041.

[0068] With this structure, the outer wedge 1041 can fit tightly against the inner side of the clamp, ensuring the force-bearing area.

[0069] In this embodiment, the outer wedge 1041 and the inner wedge 1042 include a wedge plate 10417 and trapezoidal ribs 10419 fixed on the wedge plate 10417. Two vertical trapezoidal ribs 10419 are arranged side by side at intervals on one wedge plate 10417. The opposing surfaces of the opposing trapezoidal ribs 10419 on the outer wedge 1041 and the inner wedge 1042 are vertical gear tooth surfaces 1043, and a gear 1044 meshes between the two opposing vertical gear tooth surfaces 1043.

[0070] With this structure, the trapezoidal rib 10419 can ensure that after being fixedly connected with the outer wedge block 1041 and the inner wedge block 1042, the two opposite sides of the trapezoidal rib 10419 are vertical, and after serving as the vertical gear tooth surface 1043, it can fully mesh with the gear 1044.

[0071] In this embodiment, the two sets of wedge block assemblies 104 arranged side by side share the same reduction motor 1046, and the drive shafts 1045 of the two sets of wedge block assemblies 104 are coaxially connected together; the reduction motor 1046 is mounted on the base plate extending beyond the variable cross-section column on the front side of the upper clamp 101 and the lower clamp 103; the two sets of wedge block assemblies 104 arranged side by side share a pad switching electric push rod 10415, and the longitudinal shafts 10413 of the two sets of wedge block assemblies 104 are coaxially connected together through a longitudinal plate 10420, which can pass through the rail groove 10418 of the transverse slide rail 10411.

[0072] With this structure, a pad switching electric push rod 10415 can drive the lateral translation of the gear surface pads 10412 of the two sets of wedge block assemblies 104, so that the gear motor 1046 is set on one side of the clamp. The thickness of the longitudinal plate 10420 is reduced, which will not damage the rail groove 10418 and can also ensure the stable connection of the longitudinal shaft 10413. In this embodiment, the cross-section of the vertical rail 1049, the horizontal slide bar 10410, and the rail groove 10418 is T-shaped.

[0073] With this structure, the T-shape, as the main cross-sectional form of the sliding pair type, can ensure stable sliding without slippage.

[0074] In this embodiment, two vertical rails 1049, which are paired with a vertical slider 1048, together form a vertical track. A limiting plate 10421 is fixed between adjacent vertical rails 1049 of the two vertical tracks fixed on a horizontal slider 10410. The limiting plate 10421 is slidably passed through by the longitudinal axis 10413.

[0075] With this structure, the limiting plate 10421 can ensure the transition movement of the gear surface pad 10412.

[0076] In this embodiment, both ends of the drive shaft 1045 are mounted in the transverse elongated hole 1016. One end is connected to the reduction motor 1046, and the other end is connected to the limiting wheel 10422. The limiting wheel 10422 is in close contact with the outer side of the inner wall 1013.

[0077] With this structure, the limit wheel 10422 can prevent the drive shaft 1045 from slipping when it rotates.

[0078] This invention can install the distribution beam when the clamp is in a low position and raise the distribution beam to a high position, and it can also be used to raise columns with variable cross-sections.

[0079] Example 2 like Figures 11-13 As shown, a jacking and sliding platform for a canopy formwork system includes: The frame platform unit 301, which is assembled and extended longitudinally and installed on the transversely extending distribution beam 200, includes: longitudinal I-beam main beams 3011 that form a grid by perpendicular intersections, transverse I-beam main beams 3012, longitudinal side beams 3013, transverse side beams 3014, and secondary beams 3015 located between the longitudinal I-beam main beams 3011 and the longitudinal side beams 3013. The front and rear ends of the longitudinal I-beam main beams 3011 and the longitudinal side beams 3013 are equipped with splicing plates 3016. The flange surface of the longitudinal I-beam main beams 3011 has mounting holes 302 spaced longitudinally. The I-beam rail 303 is fixedly laid on the longitudinal I-beam main beam 3011. The flange surface of the rail is also provided with mounting holes 302, which are aligned with the mounting holes 302 of the longitudinal I-beam main beam 3011 and then bolt and nut assemblies are inserted for fixing. The sliding shoe 304 is slidably installed on the I-beam rail 303, and its surface is also provided with mounting holes 302, which support the canopy formwork support truss 900. The hydraulic cylinder 305 is mounted on the I-beam rail 303, and its telescopic end is fixed on the slipper 304. The vertical rail is connected to the electric push rod 306, the base end of which is mounted on the sliding shoe 304, and the telescopic end of which is fixed to the lower chord 9012 of the canopy template support truss 900.

[0080] In this structure, the frame platform unit 301 is extended by splicing plates 3016 to extend the laying of the I-beam track 303. Mounting holes 302 are provided on the longitudinal I-beam main beam 3011 to achieve splicing with the I-beam track 303. The platform width is extended by longitudinal side beams 3013 and secondary beams 3015 to reduce the cantilever section of the canopy formwork support truss 900. This facilitates subsequent lateral movement of the canopy formwork support truss 900 and prevents the center of gravity from shifting outwards due to excessively long cantilever sections, resulting in uneven stress and potential problems. Overturning occurs; the slipper 304 is clamped under the canopy formwork support truss 900; the hydraulic cylinder 305 pushes the slipper 304 along the rail to move it on the I-beam rail 303; after the slipper 304 and the canopy formwork support truss 900 are released from fixation, the electric push rod 306 along the vertical rail is used to push the canopy formwork support truss 900 to move laterally. In addition to adjusting the lateral position of the canopy formwork support truss 900, it can also make the canopy formwork move laterally away from the main body of the canopy, allowing more folding space inside the canopy formwork.

[0081] In this embodiment, the slipper 304 includes: Slide 3041, which is slidably mounted on I-beam rail 303; The first longitudinal limiting strip 3042 is made of angle steel. Its upper limbs are installed on the bottom surfaces of both sides of the slide block 3041, and its lower limbs slide against the upper flanges of the I-beam rail 303. The transverse limiting strip 3043 is made of angle steel. Its lower limb is installed on the top surface of the slide block 3041, and its upper limb is attached to both sides of the lower chord 9012 of the canopy template support truss 900. The transverse limiting strip 3043 and the lower chord 9012 are both provided with corresponding mounting holes 302. The stiffening ribs 3044 are fixed at intervals between the upper and lower limbs of the transverse limiting strip 3043, and divide the area into a side mounting area 3045 and a middle mounting area 3046. The side mounting area 3045 is equipped with the vertical rail to the base end of the electric push rod 306; the middle mounting area 3046 is equipped with the horizontal rail to the telescopic end of the hydraulic cylinder 305.

[0082] With this structure, the slide block 3041 is supported on the lower side of the canopy formwork support truss 900; the first longitudinal limiting strip 3042 enables the slide block 3041 to move stably along the I-beam rail 303; the transverse limiting strip 3043 forms the sliding track for the lower chord 9012 of the canopy formwork support truss 900; the mounting holes 302 in the edge mounting area 3045 are used to install vertical rails towards the base end of the electric push rod 306, and the mounting holes 302 in the middle mounting area 3046 are used to install horizontal rails towards the telescopic end of the hydraulic cylinder 305.

[0083] In this embodiment, a hinge joint 307 is installed at the telescopic end of the vertical rail to the electric push rod 306. The hinge joint 307 has a through hole in the middle. A positioning sleeve 308 passes through the mounting hole 302 of the lower chord rod 9012. The internal thread hole of the positioning sleeve 308 is aligned with the through hole and is tightened by a bolt washer assembly.

[0084] With this structure, the positioning sleeve 308 clamps the hinge joint 307 with the bolt washer assembly. When the hinge joint 307 extends and retracts from the vertical rail to the electric push rod 306, it can drive the canopy template support truss 900 to move laterally through the positioning sleeve 308, making the inner space of the template larger. After moving laterally away from the main body of the canopy, it is easier to fold the template close to the main body of the canopy.

[0085] In this embodiment, an enlarged foot 309 is installed on the telescopic end of the guide rail hydraulic cylinder 305. An enlarged plate 310 is fixed to the enlarged foot 309. The enlarged plate 310 has a mounting hole 302, which is aligned with the mounting hole 302 of the lower chord 9012 and then fixed by a bolt and nut assembly.

[0086] With this structure, the enlarged foot 309 increases the force application area to prevent excessive local stress from damaging the slipper, and the enlarged plate 310 separates the enlarged foot 309 from the slipper.

[0087] In this embodiment, a second longitudinal limiting strip 311 is fixed on both sides of the base end of the rail-mounted hydraulic cylinder 305, and the second longitudinal limiting strip is slidably connected to both sides of the upper flange of the I-beam rail 303.

[0088] With this structure, after the limit is released at the base end of the hydraulic cylinder 305 along the rail, the slipper is fixed on the I-beam rail. When the retraction of the hydraulic cylinder 305 along the rail is initiated, the second longitudinal limit bar can slide easily at the base end of the hydraulic cylinder 305 along the rail.

[0089] In this embodiment, an electric latch assembly 312 is installed on the upper side of the second longitudinal limiting strip 311. The electric latch assembly 312 includes a galvanized square steel pipe column 3121, which is fixed to the second longitudinal limiting strip 311 by angle steels 3122 at the base on both sides. A latch bracket 3123 is installed on the upper end of the galvanized square steel pipe column 3121. The base end of the electric latch push rod 3124 is installed on the latch bracket 3123. The telescopic end of the electric latch push rod 3124 extends downward and is equipped with a latch plate 3125. The bottom surface of the latch plate 3125 is fixed with parallel latches 3126, which are adapted to the mounting hole 302.

[0090] With this structure, the electric latch assembly 312 controls the rise and fall of the latch 3126 to control whether to limit or unlock the hydraulic cylinder base end along the rail, so as to coordinate with the force application state and sliding state of the hydraulic cylinder along the rail, which is conducive to improving the efficiency of continuous jacking.

[0091] The overall frame unit structure of this invention adopts two sets of main beams and two sets of side beams. The main beams are made of 300 mm welded I-beams, and the two side beams are made of 20# hot-rolled channel steel. The main beams and side beams are connected by transverse main beams to form an overall frame. A formwork truss and a formwork sliding device are installed on the formwork sliding platform. The formwork sliding device consists of hydraulic cylinders and electric push rods, which are responsible for the sliding and fine-tuning of the formwork in the longitudinal and vertical directions.

[0092] Example 3 like Figures 14-17 As shown, a canopy formwork support truss includes: The bottom formwork truss 901 is arranged laterally and installed longitudinally at intervals below the foldable canopy formwork system 400. It includes an upper chord 9011, a lower chord 9012, and a web member 9013 between the upper chord 9011 and the lower chord 9012. The bottom formwork truss hinge support 902 is arranged at transverse intervals on the upper chord 9011; The back rib hinge support 903 is arranged at intervals along the longitudinal back ribs 404 of the foldable awning template system 400. The back rib plate 405 of the foldable awning template system 400 is also provided with splicing holes 409 at intervals to serve as hinge holes. The hinged support rod 904 is hinged at both ends between the back rib hinge support 903 and the bottom formwork truss hinge support 902; it is also hinged between the back rib plate 405 and the bottom formwork truss hinge support 902; and it is also hinged between the back rib hinge support 903. When two adjacent hinged support rods 904 are hinged on the bottom formwork truss hinge support 902 and the back rib hinge support 903, they should form a apex angle.

[0093] In this embodiment, the bottom formwork truss 901 is installed on the formwork support platform; it is used to provide the distribution points of the bottom formwork truss hinge support 902; the arc segment of the upper chord 9011 of the bottom formwork truss 901 can be parallel to the canopy template; when two adjacent hinged support rods 904 are hinged together on the same bottom formwork truss hinge support 902 or back rib hinge support 903, the apex angle form is convenient to form a triangular support structure as a whole, thereby utilizing the stability characteristics of triangles to make the overall support formwork more stable; The hinged support rod 904 is fixed at the splice of the back rib plate 405. At the same time, the two adjacent back rib plates 405 are also reinforced by the fasteners through which the hinged support rod 904 passes, so as to ensure the stability of the splicing of adjacent templates.

[0094] In this embodiment, bottom formwork truss brackets 905 are installed on both sides of the upper chord 9011 of the bottom formwork truss 901. The bottom formwork truss hinge support 902 is installed on the middle upper chord 9011 and the bottom formwork truss brackets 905 on both sides. At this time, one bottom formwork truss hinge support 902 has four bottom formwork truss hinge interfaces 9021 reserved. The four bottom formwork truss hinge interfaces 9021 are symmetrically distributed on both sides. Two adjacent bottom formwork truss hinge interfaces 9021 on one side are hinged to two inclined hinge support rods 904 in the form of apex angles.

[0095] With this structure, the bottom formwork truss bracket 905 extends the longitudinal installation range of the bottom formwork truss hinge support 902, which facilitates the stable installation of the bottom formwork truss hinge support 902 of the four bottom formwork truss hinge interfaces 9021, so that the canopy templates of two adjacent splices can be stably supported.

[0096] In this embodiment, the back rib hinge support 903 has two back rib hinge interfaces 9031. One back rib hinge interface 9031 is hinged together with the bottom formwork truss hinge interface 9021 to a hinged support rod 904. The other back rib hinge interface 9031 is hinged together with the back rib hinge interface 9031 on another parallel and adjacent longitudinal back rib 404 to a hinged support rod 904, thereby forming a triangular support.

[0097] With this structure, the two back rib hinge supports 903 and the bottom formwork truss hinge support 902 together form the three vertices of a triangle, and the hinged support rods 904 connecting the three vertices form the three sides of the triangle, thus forming a stable triangular support system.

[0098] In this embodiment, when the bottom formwork truss 901 is not fitted with bottom formwork truss brackets 905 on both sides of the upper chord 9011, but only the bottom formwork truss hinge support 902 is installed, the bottom formwork truss hinge support 902 is reserved with two bottom formwork truss hinge interfaces 9021, so as to hinge two inclined hinge support rods 904 in the form of apex angle. At this time, the hinge support rods 904 extend upward and are hinged to the splicing holes 409 on the back rib plate 405. One hinge support rod 904 is hinged to one side of the two spliced ​​back rib plates 405, and the other hinge support rod 904 is hinged to the other side of the two spliced ​​back rib plates 405.

[0099] With this structure, the two bottom formwork truss hinge interfaces 9021 are just used for two adjacent spliced ​​back rib plates 405. After the holes of the hinge support rod 904 are aligned with the splicing holes 409, the corresponding fasteners are used to fasten them so that the two adjacent spliced ​​back rib plates 405 are tightly attached.

[0100] In this embodiment, the hinged support rod 904 is an adjustable telescopic lead screw, which includes an upper lead screw 9041, a lead screw sleeve 9042, and a lower lead screw 9043. Both the upper lead screw 9041 and the lower lead screw 9043 are equipped with end hinge plates 9044.

[0101] With this structure, the hinged support rod 904 can be telescopically adjusted to obtain different lengths to adapt to various positions on the arc segment, making it easy for the hinged support rod 904 to form triangular structures of various specifications to meet the support requirements of different positions on the curved surface segment of the canopy template.

[0102] In this embodiment, bottom formwork truss hinge supports 902 are also installed on the end side of the lower chord 9012 of the bottom formwork truss 901 and on the vertical web members 9013 connected thereto. At this time, the bottom formwork truss hinge interface 9021 of the bottom formwork truss hinge support 902 is a single opening.

[0103] With this structure, the bottom formwork truss hinge interface 9021 is mainly used to form a hinge with the threaded rod brace assembly 427, so as to more stably support the eaves canopy formwork.

[0104] In this embodiment, bottom formwork truss brackets 905 are fitted with bottom formwork truss angle steel 906 on their bottom surfaces, and the bottom formwork truss angle steel 906 is installed on both sides of the upper chord 9011; and is fixed by bottom formwork truss tie bolt assembly 907.

[0105] With this structure, the bottom formwork truss angle steel 906 is placed on the bottom surface of the bottom formwork truss bracket 905 to strengthen the cantilever structure of the bottom formwork truss bracket 905. The bottom formwork truss bracket 905 here is made of double-splittered I-beams and welded to the upper chord 9011. After the bottom formwork truss angle steel 906 is reinforced with ribs, its rigidity is improved, making the bottom formwork truss bracket 905 more stable.

[0106] When dealing with canopy roofs with large curved surfaces, this invention can also adapt to support the corresponding curved surface templates and can reduce the height of the formwork to reduce construction risks.

[0107] Example 4 like Figures 18-30 As shown, the foldable awning template system 400 supported by Embodiment 3 includes: The bottom mold of the canopy panel unit 401 is spliced ​​and extended along the longitudinal direction; The eaves unit bottom mold 402 is spliced ​​and extended along the longitudinal direction and spliced ​​to the outside of the canopy board unit bottom mold 401. The longitudinal drip eaves unit bottom mold 4021 is distributed on it. The bottom formwork 403 of the gutter unit is spliced ​​and extended longitudinally, and spliced ​​to the inner side of the bottom formwork 401 of the canopy panel unit; Longitudinal back ribs 404 are arranged at intervals on the back of the bottom mold 401 of the canopy panel unit, the bottom mold 402 of the eaves unit, and the bottom mold 403 of the gutter unit. Back rib plate 405, which is fixed perpendicularly to the longitudinal back rib 404, is distributed at intervals on the back of the canopy board unit bottom mold 401, the eaves unit bottom mold 402 and the gutter unit bottom mold 403. The first hinge assembly 406 is installed between the longitudinal back rib 404 on the side of the bottom mold 401 of the canopy unit near the bottom mold 402 of the eaves unit and the longitudinal back rib 404 on the side of the bottom mold 402 of the eaves unit near the bottom mold 401 of the canopy unit. The first hydraulic cylinder 407 has its first base end 4071 mounted on the longitudinal back rib 404 of the bottom mold 401 of the canopy panel unit, and its first telescopic end 4072 extends outward. The support leg 408 has one end fixed between the longitudinal back ribs 404 of the bottom mold of the eaves unit, and the other end hinged to the first telescopic end of the first hydraulic cylinder 407. The lead screw diagonal brace assembly 427 includes a lead screw cylinder 4271, a lead screw 4272 threadedly connected to and extending therefrom the lead screw cylinder 4271, a limiting sleeve 4273 fixedly sleeved on the extended section of the lead screw 4272, handles 4274 fixed on both sides of the limiting sleeve 4273, limiting nuts 4275 threadedly connected to the extended end of the lead screw 4272 and located on both sides of the limiting sleeve 4273, and a hinge plate 4276 fixed on the extended end of the lead screw 4272. The outer end of the lead screw cylinder 4271 is hinged to a top support 4277, and the top support 4277 is installed on the bottom surface of the longitudinal back rib 404 of the eaves unit bottom mold 402.

[0108] With this structure, after the entire canopy formwork system is lowered and demolded, the bottom formwork 401 of the canopy panel unit is folded upwards and retracted to release the cantilever state, so as to facilitate stable longitudinal transportation to the next construction section.

[0109] The first hinge assembly 406 allows the bottom mold 401 of the canopy panel unit and the bottom mold 402 of the eaves unit to rotate. The first hydraulic cylinder 407 pushes the support leg 408, and the support leg 408 drives the bottom mold 402 of the eaves unit to flip upward. The screw rod brace assembly 427 needs to be released before the bottom mold 402 of the eaves unit flips. For example, by releasing the pin connection between the hinge plate 4276 and the hinge support of the bottom formwork truss, the screw rod brace assembly 427 can flip together with the bottom mold 402 of the eaves unit to reduce the subsequent installation process. The handle 4274 drives the screw rod 4272 to rotate by driving the limit bushing 4273 to extend and retract the length, so as to adapt to the hinge support of different heights on the formwork truss to achieve hinge. Since the limit nut 4275 restricts the position of the limit bushing 4273, the limit bushing 4273 cannot move along the screw rod 4272, but can only drive the screw rod 4272 to rotate.

[0110] In this embodiment, splicing holes 409 are provided at intervals on the longitudinal back ribs 404 and the back rib plates 405; adjacent back rib plates 405 between adjacent canopy panel unit bottom molds, between adjacent eaves unit bottom molds 402, and between adjacent gutter unit bottom molds 403 are spliced ​​together by bolt and nut assemblies through the splicing holes 409; adjacent longitudinal back ribs 404 between the canopy panel unit bottom mold 401 and the eaves unit bottom mold 402, and between the canopy panel unit bottom mold 401 and the gutter unit bottom mold 403 are spliced ​​together by bolt and nut assemblies through the splicing holes 409.

[0111] With this structure, the splicing hole 409 provides a convenient way for template assembly and integrated installation of various equipment.

[0112] In this embodiment, the first base end 4071 of the first hydraulic cylinder 407 is mounted on the longitudinal back rib 404 through the first hinge seat 410; the first hinge seat 410 is connected by a bolt and nut assembly that aligns with the splicing hole 409 and passes through it, and the first hinge seat 410 is hinged to the first base end 4071.

[0113] With this structure, the first base end 4071 of the first hydraulic cylinder 407 can be stably assembled on the longitudinal back rib 404.

[0114] In this embodiment, a guardrail assembly 411 is installed on the longitudinal back rib 404 installed on the top of the eaves unit bottom mold 402. The guardrail assembly 411 includes a base 4111 installed on the longitudinal back rib 404, a railing 4112 installed on the base 4111, a frame 4113 installed on both sides of the railing 4112, and a perforated steel plate protective net 4114 laid and fixed on the frame 4113.

[0115] With this structure, the guardrail assembly 411 can improve the protection against airborne conditions after installation, which is conducive to ensuring the safety of construction workers. The guardrail assembly 411 can be disassembled in advance during the flipping process of the eaves unit bottom formwork 402 to reduce the number of parts during the flipping process and ensure the safety of the flipping. Alternatively, it can be flipped together. At this time, the guardrail assembly 411 should be checked to see if it is firmly fixed or additional reinforcement measures should be added.

[0116] In this embodiment, an inner mold auxiliary support assembly 412 is installed on the longitudinal back rib 404 mounted on the top of the eaves unit bottom mold 402. The inner mold auxiliary support assembly 412 includes an inverted U-shaped seat 4121 and an inner mold auxiliary support 4122. The inverted U-shaped seat 4121 has base plates 4123 on both sides, and the base plates 4123 are fixed on the longitudinal back rib 404. The inner mold auxiliary support 4122 is inserted between the inverted U-shaped seat 4121 and the longitudinal back rib 404 and fixed therein. The inner mold auxiliary support 4122 extends inward.

[0117] With this structure, the inner mold auxiliary support component 412 is used to install the inner mold truss. The inner mold truss is used to install the inner mold and provide effective support. The inner mold is easy to use in conjunction with the eaves unit bottom mold 402, the canopy board unit bottom mold 401 and the gutter unit bottom mold 403 to facilitate the overall shaping of the concrete.

[0118] In this embodiment, a lower drainage pipe trench unit template 413 is spliced ​​on the inner side of the gutter unit bottom mold 403. The back of the lower drainage pipe trench unit template 413 also has longitudinal back ribs 404 and back ribs 405. A first bracket 414 is installed between the longitudinal back ribs 404 at the bottom of the lower drainage pipe trench unit template 413. The first bracket 414 is L-shaped, with its bottom extending towards the gutter unit bottom mold 403. A pad 415 is installed on the bottom surface of the longitudinal back ribs 404 at the bottom of the gutter unit bottom mold 403. 5 is hinged to the extension end of the first bracket 414 via a second hinge assembly 416. A second hinge seat 417 is installed at the bottom of the first bracket 414. A second hydraulic cylinder 418 is hinged to the bottom of the second hinge seat 417. The second telescopic end 4182 of the second hydraulic cylinder 418 is hinged to the second hinge seat 417. The second base end 4181 of the second hydraulic cylinder 418 is hinged to a third hinge seat 419. The third hinge seat 419 is installed on the longitudinal back rib 404 in the middle of the bottom surface of the bottom mold 403 of the gutter unit.

[0119] With this structure, the lower drainage pipe trench unit template 413 is mainly used to form the trench for installing the lower drainage pipe. The trench needs to be connected to the upper gutter so that the water falling from the upper gutter can be collected through the lower drainage pipe and discharged to the bottom by the downpipe. The second hydraulic cylinder 418 drives the second hinge seat 417 to rotate, that is, drives the lower drainage pipe trench unit template 413 to move around to the bottom mold 403 of the gutter unit to release the cantilever state and make it more stable during subsequent transportation.

[0120] In this embodiment, the lower drainage pipe trench unit template 413 includes a lower drainage pipe trench unit bottom mold 4131 and a lower drainage pipe trench unit side mold 4132; a second bracket 420 is installed at the bottom of the longitudinal back rib 404 on the back side of the lower drainage pipe trench unit side mold 4132; a fixed support 421 is installed at the bottom of the second bracket 420, the fixed support 421 extends toward the lower drainage pipe trench unit bottom mold 4131, and a third hinge assembly 422 is installed between the longitudinal back rib 404 on the bottom surface of the lower drainage pipe trench unit bottom mold 4131 and the extended end of the fixed support 421; the second hinge assembly 416 and the third hinge assembly 422 are connected by a pivot joint 423 and a fixed joint 424 with a pin shaft, the fixed joint 424 is fixed to an object that does not need to rotate, and the pivot joint 423 is fixed to an object that needs to rotate, so as to realize the hinge of the two objects.

[0121] With this structure, the bottom mold 4131 and side mold 4132 of the lower drainage pipe trench unit can also rotate to further reduce the cantilever structure. This allows the side mold 4132 of the lower drainage pipe trench unit to also be moved around to the bottom mold 403 of the gutter unit. The tie rod and other support structures are then fixed through splicing holes to prevent movement. During transportation, the cantilever structure is retracted as a whole, so the center of gravity is further inward, making transportation more stable. The top mold of the lower drainage pipe trench unit can also be installed on the side mold 4132 of the lower drainage pipe trench unit. The bottom horizontal back rib of the top mold of the lower drainage pipe trench unit is assembled with the back rib of the left and right side molds 4132 of the lower drainage pipe trench unit through splicing holes.

[0122] In this embodiment, the second bracket 420 is made of double-splitter I-beams, with an inner angle steel 425 and an outer angle steel 426 fixedly installed between the two I-beams. The upper limb of the inner angle steel 425 is attached to the side of the longitudinal back rib 404 of the bottom mold 4131 of the lower drainage pipe trench unit and covers the splicing hole 409, while its lower limb is attached to the lower flange of the double-splitter I-beam for fixation. The lower limb of the outer angle steel 426 is close to the surface of the upper limb of the inner angle steel 425, and its upper limb is close to the upper flange of the double-splitter I-beam for fixation. Bolt and nut assemblies are used to fix the upper limb of the inner angle steel 425, the lower limb of the outer angle steel 426, and the corresponding splicing hole 409.

[0123] With this structure, the inner angle steel 425 and the outer angle steel 426 make the connection of the double I-beams more stable, and are more firmly fixed to the longitudinal back rib 404 by the bolt and nut assembly, so that the second bracket 420 can stably support the side mold 4132 of the lower drainage pipe trench unit. Before flipping, the bolt and nut assembly needs to be removed.

[0124] In this embodiment, the first hinge assembly 406 includes a first hinge support 4061 fixed to the longitudinal back rib 404 on the inner side of the bottom mold of the eaves unit 402 and a second hinge support 4062 fixed to the longitudinal back rib 404 on the outer side of the bottom mold of the canopy unit 401; at least two V-shaped hinges 4063 are provided between the first hinge support 4061 and the second hinge support 4062, the first link 40631 of the V-shaped hinge 4063 is hinged to the first hinge support 4061; the second link 40632 of the V-shaped hinge 4063 is hinged to the second hinge support 4062. The first hinge assembly 406 is arranged in pairs as a group. The first hinge support 4061 and the second hinge support 4062 have different lengths. In the same group, the first hinge assembly 406 is arranged in opposite directions and adjacent to each other. When the first hinge support 4061 and the second hinge support 4062 are on the same side, they are paired with each other and are fixed together on the base 4065. The base 4065 is then fixed on the longitudinal back rib 404. Adjacent V-shaped hinges 4063 are arranged in an alternating manner. A common pin 4064 is provided at the intersection of the V-shaped hinges 4063.

[0125] This structure expands the rotation radius, allowing the upper edge of the eaves unit bottom mold 402 to rotate along the upper edge of the canopy board unit bottom mold 401. This ensures that the templates are flat while maintaining their flatness, without affecting the flatness of the templates.

[0126] In this embodiment, a T-shaped rail 4022 is fixed on the bottom mold 402 of the eaves unit, and a T-shaped groove 4023 is built into the bottom mold 4021 of the drip eaves unit to slide and adapt to the T-shaped rail 4022. A groove 4024 is opened on the end face of the bottom mold 4021 of the drip eaves unit, and a pull opening 4025 is opened on the bottom surface of the groove 4024.

[0127] With this structure, if the bottom mold 402 of the eaves unit is damaged, it is easy to remove the bottom mold 402 of the eaves unit to replace the parts. This is better than the situation where the entire template needs to be replaced if the bottom mold 402 of the eaves unit is damaged due to welding or integral molding.

[0128] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several equivalent substitutions or obvious modifications can be made without departing from the concept of the present invention, and all such modifications, achieving the same performance or purpose, should be considered within the scope of protection of the present invention.
