Description

Technical Field

[0001] This invention belongs to the field of building equipment, specifically a sliding top support connection device used in conjunction with a socket-type disc buckle frame. Background Technology

[0002] The beam-slab co-support technology is a feature of the socket-type disc-lock steel pipe scaffold. In the existing beam-slab co-support construction methods, double channel steel is generally used as a horizontal bar, with two vertical bars connected at both ends and two vertical bars with top supports fixed in the middle. The beam-slab co-support is achieved through the combination of the two types of members. Because the support position and support angle of the top support are set constantly, this construction method cannot well adapt to the support of beams and slabs in different positions or with a certain tilt angle due to installation errors, which is not conducive to its use.

[0003] Therefore, the present invention provides a sliding top support connecting device for use with a socket-type disc buckle frame. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a sliding top support connecting device for use with a socket-type disc buckle frame, comprising two uprights, a horizontal bar set at the middle position of the two uprights, two sliding seats slidably sleeved on the outer circumferential surface of the horizontal bar, sliding seats slidably sleeved on the outer circumferential surface of the uprights, and a movable top support mechanism for supporting beams and plates, wherein the side of the sliding seats that is close to each other is fixed to the surfaces on both sides of the horizontal bar;

[0006] The movable support mechanism includes a sliding extension component and an adjustable support component;

[0007] The adjusting support assembly includes connecting seats on both sides of the top of the horizontal rod, a top support baffle on the top of the connecting seats, a movable shaft rotatably connected to the middle position of the top of the connecting seats, a connecting sleeve fixedly sleeved at the middle position of the outer circumference of the movable shaft, a rotating component acting on the movable shaft, a limiting ring slidably inserted at both sides of the connecting seats, a plurality of magnetic grooves evenly opened on the opposite side of the limiting rings, a support seat fixed to both sides of the bottom of the connecting seats, a sliding shaft slidably inserted at the middle position of the support seat, and a sliding fixing component acting on the sliding shaft. The top of the connecting sleeve is fixed to the surface of the top support baffle.

[0008] Preferably, the sliding extension assembly includes collars slidably sleeved on both sides of the top of the outer peripheral surface of the horizontal rod, a vertical cylinder fixed to the top of the collars, a first threaded rod rotatably connected to the middle position of the inner cavity of the vertical cylinder, a threaded sleeve threadedly connected to the outer peripheral surface of the first threaded rod, a driving component acting on the first threaded rod, and a guiding component, wherein the top of the threaded sleeve is fixed to the surface of the bottom of the adjacent connecting seat.

[0009] Preferably, the sliding extension assembly further includes a plurality of first insertion holes evenly provided at one end of the outer peripheral surface of the horizontal rod, a first bolt threaded to one end of the collar, abutment grooves provided at both ends of the inner peripheral surface of the collar, and a limiting strip inserted into the abutment groove, one end of the limiting strip being fixed to the outer peripheral surface of the horizontal rod.

[0010] Preferably, the rotating component includes a first spur gear fixedly sleeved on both sides of the outer circumferential surface of the movable shaft, a first rack meshing with the bottom of the first spur gear, a connecting plate fixed at the middle position of the two first racks, and a second threaded rod threadedly connected to one end of the connecting seat. The bottom of the connecting plate is slidably connected to the inner cavity of the top surface of the connecting seat, and one end of the second threaded rod is embedded in the inner cavity of the connecting seat and is rotatably connected to the connecting plate at the position where the connecting plate is embedded in the inner cavity of the connecting seat.

[0011] Preferably, the sliding component includes a connecting plate fixed to the side of the insert shaft away from the adjacent position limiting ring, a spring sleeved on the outer peripheral surface of the insert shaft, and an electromagnetic block fixed to the support base at the bottom of the insert shaft at the adjacent position. One side of the spring is fixed to the surface of the adjacent position support base, and the other side of the spring is fixed to the surface of the connecting plate. The inner cavity of the magnetic suction groove is arc-shaped, and the outer peripheral surface of the portion of the insert shaft embedded in the adjacent position magnetic suction groove is arc-shaped.

[0012] Preferably, the driving component includes a rotating rod rotatably connected to one end of the outer peripheral surface of the vertical cylinder and two bevel gears fixedly sleeved on the outer peripheral surface of the rotating rod and the outer peripheral surface of the first threaded rod at the bottom position of the threaded sleeve. The two bevel gears are meshed together. The guiding component includes limiting grooves formed at both ends of the outer peripheral surface of the threaded sleeve and limiting strips inserted into the limiting grooves. The ends of the limiting strips that are far apart from each other are fixed to the inner peripheral surface of the vertical cylinder.

[0013] Preferably, the movable top support mechanism further includes a translation limiting component for limiting the horizontal bar. The translation limiting component includes a movable rod rotatably connected to the inner cavity of the slide block at a position on one side of the upright, a third sprocket fixedly sleeved on the outer circumferential surface of one end of the movable rod, a second rack fixed to the inner cavity of the upright, and a transmission component for connecting the two movable rods. The third sprocket is meshed with a second bolt at an adjacent position. The translation limiting component also includes a plurality of second insertion holes evenly opened on the outer circumferential surface of the upright on opposite sides, a second bolt threadedly connected to the side of the slide block away from the horizontal bar, and a third threaded rod rotatably connected to the bottom of one of the second insertion holes on the outer circumferential surface of the upright. The third threaded rod is threadedly connected to one of the slide blocks.

[0014] Preferably, the transmission component includes a rotating shaft rotatably connected to one of the slides on one side of the movable rod, a pulley fixedly sleeved on one end of the outer peripheral surface of the rotating shaft and the other end of the outer peripheral surface of the other movable rod, a connecting belt disposed at the middle position of the two pulleys, and a second spur gear fixedly sleeved on the other end of the outer peripheral surface of one of the movable rods and the other end of the outer peripheral surface of the rotating shaft, wherein the two second spur gears are meshed together.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention allows the horizontal rod to move vertically under the constraint of the collar and the upright rod. The upright cylinder can slide along the outer circumference of the horizontal rod to adjust the position of the two top support baffles that provide support. The top support baffles can change angle through the meshing action between the first rack and the first spur gear, thereby adjusting the angle of the top support baffles to adapt to beams and slabs with a certain tilt angle due to installation errors. This improves the applicability of the device, simplifies the design and construction of beam and slab formwork, reduces construction difficulty, and solves the problem of fixed top support position in traditional co-support technology, which requires disassembly and reassembly for beams with different cross-sections.

[0017] 2. When the horizontal rod slides vertically, the meshing action between the two sets of third sprockets and the second rack, due to the opposite rotation directions of the two third sprockets, can limit the horizontal rod, allowing it to move smoothly in the vertical direction. This avoids the horizontal rod tilting during vertical movement, which would affect the support effect on the beam and plate, thus further improving the applicability of the device.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1:

[0031] like Figure 1-9 As shown, a sliding top support connecting device for use with a socket-type disc buckle frame according to an embodiment of the present invention includes two uprights 1, a horizontal bar 2 set at the middle position of the two uprights 1, two sliding blocks 3 slidably sleeved on the outer periphery of the horizontal bar 2, sliding blocks 3 slidably sleeved on the outer periphery of the uprights 1, and a movable top support mechanism for supporting beams and plates. The side of the sliding blocks 3 that is close to each other is fixed to the surfaces on both sides of the horizontal bar 2.

[0032] When in use, this device, which is used in conjunction with the socket-type disc buckle scaffold, can be used for formwork support, which can greatly reduce the number of scaffold uprights. It makes fuller use of the high stability and large load-bearing capacity of the load-bearing disc buckle scaffold, and ensures the axial transmission of the load. It efficiently simplifies the design and construction of beam and slab structure formwork, reduces construction difficulty, saves materials, and avoids uneven settlement caused by different loads on the bottom of the beam and the bottom of the slab. The device can slide along the outer circumference of the upright 1 through the sliding seat 3, thereby adjusting the height of the horizontal bar 2 in the vertical direction. This allows the movable top support mechanism on both sides of the top of the horizontal bar 2 to be moved closer to the required support position. The movable top support mechanism can adjust the support position in the horizontal direction and can adapt to the tilt angle of the support surface when supporting.

[0033] like Figure 1-9 As shown, the movable support mechanism includes a sliding extension assembly and an adjustable support assembly;

[0034] The adjustment support assembly includes connecting seats 16 on both sides of the top of the horizontal bar 2, a top support baffle 17 on the top of the connecting seats 16, a movable shaft 18 rotatably connected to the middle position of the top of the connecting seats 16, a connecting sleeve 19 fixedly sleeved at the middle position of the outer circumference of the movable shaft 18, a rotating component acting on the movable shaft 18, a limiting ring 24 slidably inserted at both sides of the connecting seats 16, a plurality of magnetic suction grooves 25 evenly opened on the limiting rings 24 away from each other, a support seat 26 fixed to both sides of the bottom of the connecting seats 16, a sliding shaft 27 slidably inserted at the middle position of the support seat 26, and a sliding component acting on the sliding shaft 27. The top of the connecting sleeve 19 is fixed to the surface of the top support baffle 17.

[0035] The rotating component causes the movable shaft 18 to rotate, thereby allowing the top support baffle 17 to change angle. This enables it to adapt to beams with a certain tilt angle due to installation errors, thus improving the applicability of the device. During this process, the limiting ring 24 can limit the movement trajectory of the top support baffle 17, making the angle change more stable. Furthermore, the sliding component allows the insert shaft 27 to be embedded in the adjacent magnetic groove 25, thereby limiting the limiting ring 24. This provides support and limitation at the four corners of the top support baffle 17, improving its stability.

[0036] like Figure 1-9 As shown, the rotating component includes a first spur gear 20 fixedly sleeved on both sides of the outer peripheral surface of the movable shaft 18, a first rack 21 meshing with the bottom of the first spur gear 20, a connecting plate 23 fixed at the middle position of the two first racks 21, and a second threaded rod 22 threadedly connected to one end of the connecting seat 16. The bottom of the connecting plate 23 is slidably connected to the inner cavity of the top surface of the connecting seat 16, and one end of the second threaded rod 22 is embedded in the inner cavity of the connecting seat 16 and is rotatably connected to the connecting plate 23 at the position where the connecting plate 23 is embedded in the inner cavity of the connecting seat 16.

[0037] By rotating the second threaded rod 22, the inner cavity of the connecting seat 16 can act as a stop and limit to the connecting plate 23. Thus, when the second threaded rod 22 and the connecting seat 16 extend horizontally through the cooperation of the threaded structure, the connecting plate 23 can be driven to move horizontally. This allows the first rack 21 to move horizontally and mesh with the first spur gear 20, thereby causing the movable shaft 18 to rotate and the connecting sleeve 19 to change angle, which in turn causes the top support baffle 17 to change angle.

[0038] like Figure 1-9 As shown, the sliding component includes a connecting plate 28 fixed to the side of the insert shaft 27 away from the adjacent position limiting ring 24, a spring 29 sleeved on the outer peripheral surface of the insert shaft 27, and an electromagnetic block 30 fixed to the support base 26 at the bottom of the insert shaft 27 in the adjacent position. One side of the spring 29 is fixed to the surface of the adjacent position support base 26, and the other side of the spring 29 is fixed to the surface of the connecting plate 28. The inner cavity of the magnetic suction groove 25 is arc-shaped, and the outer peripheral surface of the part of the insert shaft 27 embedded in the adjacent position magnetic suction groove 25 is arc-shaped.

[0039] Before adjusting the angle of the top support baffle 17, first turn off the electromagnetic block 30. When the limiting ring 24 rotates, the inner cavity of the magnetic groove 25 will abut against the arc-shaped surface of the insertion shaft 27 embedded in the inner cavity of the magnetic groove 25, so that the insertion shaft 27 slides in the horizontal direction, thereby allowing the connecting plate 28 to stretch the adjacent spring 29 to deform. After the top support baffle 17 is adjusted to the appropriate angle, the insertion shaft 27 can be driven by the rebound force to embed the insertion shaft 27 into the interior of another magnetic groove 25. Then turn on the electromagnetic block 30 so that the insertion shaft 27 can be fixed in a fixed state under the magnetic attraction between the insertion shaft 27 and the surface of the electromagnetic block 30, thereby limiting the limiting ring 24 to improve the stability of the top support baffle 17 when supported.

[0040] like Figure 1-9As shown, the sliding extension assembly includes a collar 4 that is slidably sleeved on both sides of the top of the outer peripheral surface of the horizontal rod 2, a vertical cylinder 5 fixed to the top of the collar 4, a first threaded rod 10 rotatably connected to the middle position of the inner cavity of the vertical cylinder 5, a threaded sleeve 11 threadedly connected to the outer peripheral surface of the first threaded rod 10, a driving component acting on the first threaded rod 10, and a guiding component. The top of the threaded sleeve 11 is fixed to the surface of the bottom of the adjacent connecting seat 16.

[0041] The first threaded rod 10 is rotated by the driving component, which allows the threaded sleeve 11 to move vertically under the limiting action of the guide component and the cooperation of the threaded structure between the threaded sleeve 11 and the first threaded rod 10. This allows the height of the top support baffle 17 to be adjusted so that the top support baffle 17 can be closer to the height of the support. Since the collar 4 can slide on the outer circumference of the horizontal rod 2, the support position of the adjustment support assembly in the horizontal direction can be adjusted. This solves the problem of the fixed top support position in the traditional co-support technology, which requires disassembly and reassembly when encountering beams with different cross-sections.

[0042] like Figure 1-9 As shown, the sliding extension assembly also includes a plurality of first insertion holes 8 evenly opened at one end of the outer peripheral surface of the horizontal rod 2, a first bolt 9 threaded to one end of the collar 4, abutment grooves 7 opened at both ends of the inner peripheral surface of the collar 4, and a limiting strip 6 inserted inside the abutment grooves 7, one end of the limiting strip 6 being fixed to the outer peripheral surface of the horizontal rod 2.

[0043] By sliding the collar 4 on the outer circumference of the horizontal rod 2, the position of the adjustment support assembly in the horizontal direction can be adjusted. By rotating the first bolt 9, it extends horizontally and embeds into the interior of the first insertion hole 8 at the adjacent position under the cooperation of the threaded structure of the collar 4, thereby positioning the collar 4. When the collar 4 slides in the horizontal direction, it can slide smoothly in the horizontal direction under the resistance and limitation of the inner wall of the contact groove 7 and the surface of the limiting strip 6.

[0044] like Figure 1-9 As shown, the driving component includes a rotating rod 14 rotatably connected to one end of the outer circumferential surface of the vertical cylinder 5, and two bevel gears 15 fixedly sleeved on the outer circumferential surface of the rotating rod 14 and the outer circumferential surface of the first threaded rod 10 at the bottom position of the threaded sleeve 11. The two bevel gears 15 are meshed together.

[0045] By rotating the rotating rod 14, one of the bevel gears 15 can be rotated, thereby enabling the first threaded rod 10 to be in a rotating state through the meshing action between the two bevel gears 15.

[0046] like Figure 1-9As shown, the guide component includes limiting grooves 12 formed at both ends of the outer peripheral surface of the threaded sleeve 11 and limiting strips 13 inserted inside the limiting grooves 12. The ends of the limiting strips 13 that are far apart from each other are fixed to the inner peripheral surface of the vertical cylinder 5.

[0047] When the threaded sleeve 11 is driven by the threaded structure of the first threaded rod 10, the inner wall of the limiting groove 12 will come into contact with the limiting strip 13, so that the threaded sleeve 11 can only move in the vertical direction, thereby limiting the movement trajectory of the threaded sleeve 11.

[0048] Example 2:

[0049] While the above method solves the problem of not being able to adapt well to beams and slabs in different positions or with a certain tilt angle due to installation errors, in actual use, the sliding horizontal bar 2 is prone to tilting when its height is adjusted, which can affect the support effect of the movable top support mechanism.

[0050] like Figures 1 to 9 As shown in Example 1, another embodiment of the present invention is as follows:

[0051] Therefore, such as Figures 1 to 9 As shown, the movable top support mechanism also includes a translation limiting component for limiting the horizontal rod 2. The translation limiting component includes a movable rod 38 rotatably connected to the inner cavity of the slide block 3 at a position on one side of the upright rod 1, a third spur gear 40 fixedly sleeved on the outer circumferential surface of one end of the movable rod 38, a second rack 34 fixed to the inner cavity of the upright rod 1, and a transmission component for connecting the two movable rods 38. The third spur gear 40 is meshed with the second bolt 32 at an adjacent position.

[0052] When the user slides the horizontal bar 2 vertically, the slide block 3 moves vertically upward along the outer circumference of the adjacent upright bar 1, allowing the horizontal bar 2 to approach the height of the support position. During the vertical movement of the horizontal bar 2, the second rack 34 meshes with the third sprocket 40, causing the pulley 36 to rotate. During this process, under the action of the transmission component, the two third sprockets 40 can rotate synchronously in opposite directions, ensuring that the horizontal bar 2 maintains the same speed on both sides during vertical movement, thus preventing the horizontal bar 2 from shifting during vertical movement.

[0053] like Figures 1 to 9As shown, the translation limiting component also includes a plurality of second insertion holes 31 evenly opened on the outer peripheral surface of the upright 1 on a side away from each other, a second bolt 32 threadedly connected to the slide block 3 on the side away from the horizontal bar 2, and a third threaded rod 33 rotatably connected to the bottom of one of the second insertion holes 31 on the outer peripheral surface of the upright 1. The third threaded rod 33 is threadedly connected to one of the slide blocks 3.

[0054] When the horizontal bar 2 moves vertically to the required height, the second bolt 32 is rotated, allowing it to engage with the adjacent second insertion hole 31 through the threaded structure between the bolt and the adjacent slide block 3. This restrains the horizontal bar 2, securing it at the required height. By rotating the third threaded rod 33, the slide block 3, under the resistance and restraint of the vertical bar 1 and the engagement of the threaded structure with the third threaded rod 33, moves smoothly vertically, driving the horizontal bar 2 to move smoothly vertically as well.

[0055] like Figures 1 to 9 As shown, the transmission component includes a rotating shaft 35 rotatably connected to one of the slide blocks 3 located on one side of the movable rod 38, a pulley 36 fixedly sleeved on one end of the outer peripheral surface of the rotating shaft 35 and the other end of the outer peripheral surface of the other movable rod 38, a connecting belt 37 disposed at the middle position of the two pulleys 36, and a second spur gear 39 fixedly sleeved on the other end of the outer peripheral surface of one of the movable rods 38 and the other end of the outer peripheral surface of the rotating shaft 35. The two second spur gears 39 are meshed together.

[0056] When one of the movable rods 38 rotates, the meshing action between the two second spur gears 39 causes the rotating shaft 35 to rotate at the same speed but in opposite directions. This drives one of the pulleys 36 to rotate, and under the connection of the connecting belt 37, the two movable rods 38 can rotate in opposite directions but at the same speed. This causes the two third spur gears 40 to rotate in opposite directions but at the same speed. As a result, when the third spur gears 40 mesh with the second rack 34, the movement speed on both sides of the horizontal rod 2 is the same, thus ensuring that the horizontal rod 2 will not deviate when moving vertically.

[0057] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.
