Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly to a quick-disassembly floor support member. Background Art

[0002] A composite floor slab is an assembled integral floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. The composite floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the finishing layer. It is suitable for high-rise buildings and large-span buildings with relatively high requirements for overall stiffness. Before pouring the composite floor slab, it needs to be supported on the beam structure. Due to the arrangement of structures such as pre-set steel bars at the upper end of the beam, insufficient support area can be provided. Therefore, floor support members are required. Existing floor support members can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] Patent document CN114658114A discloses a steel beam floor support structure on June 24, 2022. The technical solution thereof includes: a steel beam, a cross beam, a mounting seat and a positioning block. An inner cavity is formed in the steel beam, and a mounting sliding hole is provided on the steel beam. The mounting seat is slidably arranged in the mounting sliding hole, and the positioning block is fixedly arranged in the inner cavity. A placing surface for placing the cross beam is formed on the mounting seat, and the mounting seat restricts the horizontal movement of the cross beam. The mounting seat includes a bottom frame, a docking rod and a connecting arm connecting the bottom frame and the docking rod. One end of the connecting arm is rotatably matched with the docking rod, and the other end is fixedly connected with the bottom frame. The docking rod is located in the inner cavity and forms a steering slide with the mounting sliding hole. The horizontal height of the bottom frame is below the docking rod, and the placing surface is formed on the bottom frame. When the docking rod and the positioning block are fixed, an independent damping part is formed at the position where the steel beam abuts against the bottom frame. The damping part is rotatably connected with the steel beam, and a damping counterweight assembly is connected to the damping part.

[0004] As in the prior art of the above patent, the support structure of the floor slab is often fixed to the beam structure and cannot be disassembled, which will lead to occupying part of the ceiling space and affecting the subsequent use of the building space, or being inconvenient to disassemble and affecting the construction efficiency. Therefore, there is an urgent need for a quick-disassembly floor support member to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a quick-disassembly floor support member to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A quick-release floor support member, which is used to connect a beam body and support a floor slab, includes: a pipe body, which is slidably arranged through the beam body; a quick-release member, which is detachably arranged at the end of the pipe body, and a support plate is connected thereto through a support assembly, and the support plate is used to support a square timber; the support assembly includes a sleeve fixedly connected to the quick-release member and a telescopic member fixedly connected to the support plate, and the sleeve is movably connected to the telescopic member and is limited by a pin.

The telescopic direction of the telescopic member is consistent with the extending direction of both ends of the limiting member.

[0010] Preferably, the calibration assembly includes a calibration member arranged on the calibration plate, and the limiting member is slidably arranged through the calibration member.

[0011] Preferably, the calibration assembly includes a chute arranged on the calibration plate. The chute includes a calibration section corresponding to directly above the axis of the pipe body and a rotating section arranged around the axis of the pipe body. A sliding column slidably connected to the chute is connected to the calibration member.

[0012] Preferably, the calibration assembly includes a movable groove arranged inside the calibration plate. A ring sleeve is rotatably arranged in the movable groove. A guide rod is arranged on the ring sleeve. A guide sleeve is sleeved on the guide rod, and the guide sleeve is fixedly connected to the sliding column.

[0013] Preferably, a level is rotatably arranged on the calibration plate, and the rotation of the level is linked to the rotation of the pipe body. [[ID=,19]]

[0014] Preferably, a key body is arranged on the inner wall of the quick-release member, and a key groove matching the key body is arranged on the outer wall of the end of the pipe body.

[0015] Preferably, a clamping rod is movably arranged at the outermost end of the key groove, and the movement of the clamping rod is linked to the rotation of the pipe body through a linkage assembly arranged inside the pipe body.

[0017] In the above technical solution, the beneficial effects of the present invention are:

[0018] The quick-release floor support member extends from the side of the beam body by arranging a pipe body, and then supports the pallet through a support assembly to lift the square timber for supporting the floor slab. Then, the composite layer concrete is poured. After the concrete strength reaches the standard and the floor slab is fixed to the beam body, the pin can be pulled out to make the telescopic member contract into the kit, thereby reducing the height of the pallet and separating the square timber from the floor slab for easy removal. Moreover, by separating the quick-release member from the pipe body, the pipe body can then be disassembled from the beam body, realizing the quick-release function of the entire floor support member and improving the convenience of the device.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0035] Please refer to Figure 1-10 , a quick-release floor support provided by an embodiment of the present invention, which is used to connect a beam body and support a floor slab, and includes: a pipe body 1 that slidably penetrates through the beam body; a quick-release part 2 that is detachably arranged at the end of the pipe body 1, and a support plate 3 is connected thereto through a support assembly, and the support plate 3 is used to support a square timber; the support assembly includes a kit 4 fixedly connected to the quick-release part 2 and a telescopic part 5 fixedly connected to the support plate 3, and the kit 4 is movably connected to the telescopic part 5 and is limited by a pin 22.

[0036] Specifically, the beam body can preferably be a precast member. During the precasting process of the beam body, a plurality of through holes are left on the side surface. Both the through holes and the pipe body 1 are preferably cylindrical. The inner diameter of the through holes matches the outer diameter of the pipe body 1. The pipe body 1 can axially move within the through holes. The quick-release member 2 is in an "Ω" shape, preferably made of metal and having a certain elasticity. The outer diameter of the pipe body 1 matches the elastic adjustable inner diameter range of the quick-release member 2. Both ends of the quick-release member 2 are provided with sheet-like structures and have openings. After the quick-release member 2 is sleeved on the pipe body 1, it is connected through the two ends and fastened with bolts and nuts to achieve the fixing method of clamping the pipe body 1. At the same time, after the bolts and nuts are loosened and tightened, the quick-release member 2 can be directly slid off from the end of the pipe body 1. The support plate 3 is in a "U" shape, and the inner wall spacing is not less than the outer dimension of the square timber. When the square timber is supported by the support plate 3, it is in a state approximately parallel to the side wall of the beam body, and the upper end surface of the square timber is coplanar with the upper end surface of the concrete entity of the beam body. The kit 4 is a thin-walled cylindrical shape, with both ends penetrating, preferably a rectangular straight cylinder or a polygonal straight cylinder. The shape of the telescopic member 5 matches that of the kit 4. The kit 4 is provided with insertion holes penetrating the opposite side walls, and the telescopic member 5 is provided with a plurality of positioning holes penetrating the opposite side walls. The plurality of positioning holes are arranged at intervals in the extending direction of both ends of the telescopic member 5. The insertion holes correspond to the positioning holes, and both the insertion holes and the positioning holes match the pin 22. The plurality of positioning holes correspond to different lengths of the telescopic member 5 extending out of the kit 4, that is, when the support assembly supports the square timber, it corresponds to different heights of the support plate 3 relative to the quick-release member 2, so that the support height of the support assembly can be adjusted. The two ends of the pipe body 1 are arranged on the opposite sides of the beam body respectively, and the support plate 3 can be set to support the situation where floors are built on both sides of the beam body. In the actual use of this technical solution, a set of quick-release members 2, support assemblies and support plates 3 can be installed at one end of the pipe body 1, and then the other end of the pipe body 1 passes through the through hole on the beam body until the lengths of both ends of the pipe body 1 extending out are appropriate. Then, another set of quick-release members 2, support assemblies and support plates 3 are installed at the other end of the pipe body 1. Thus, with the help of the support plate 3, the square timber can be supported at a suitable height on the upper surface of the corresponding beam body, and then the precast floor slab can be supported. Then, the composite layer concrete is poured. After the concrete strength reaches the standard, the floor slab is fixed to the beam body. Then, by pulling out the pin 22, the telescopic member 5 can be contracted into the kit 4, thereby reducing the height of the support plate 3, separating the square timber from the floor slab, facilitating the removal of the square timber first, then separating the quick-release member 2 from the pipe body 1, and then removing the pipe body 1 from the beam body, thus realizing the quick-release function of the entire floor support member.

[0037] Compared with the prior art, a quick-release floor support member proposed in an embodiment of the present invention extends the pipe body 1 from the side of the beam body, and then supports the support plate 3 through the support assembly to support the square timber for supporting the floor slab. Then, the composite layer concrete is poured. After the concrete strength reaches the standard and the floor slab is fixed to the beam body, the expansion pin 22 can be pulled out to make the telescopic member 5 contract into the sleeve 4, thereby reducing the height of the support plate 3, separating the square timber from the floor slab, and facilitating removal. Moreover, by separating the quick-release member 2 from the pipe body 1, and then the pipe body 1 can be disassembled from the beam body, realizing the quick-release function of the entire floor support member and improving the convenience of the device.

[0038] As a preferred technical solution of this embodiment, two limiting members 6 are detachably arranged on the pipe body 1 on opposite sides of the beam body. Specifically, through holes matching the limiting members 6 are formed on the pipe body 1, and the axis of the through holes is vertically intersected with the axis of the pipe body 1; the distance between the two through holes satisfies that when the pipe body 1 penetrates the beam body, both sides of the beam body can be exposed; the two limiting members 6 protrude from the outer surface of the pipe body 1 by connecting the pipe body 1, and thus the lengths of both ends of the pipe body 1 extending out of opposite sides of the beam body can be limited. The limiting member 6 can preferably be a bolt, and after penetrating the pipe body 1, it is fixed by connecting a nut at the tail end.

[0039] As a preferred technical solution of this embodiment, no less than two pipe bodies 1 penetrate through the beam body, and the same calibration plate 7 is sleeved on the multiple pipe bodies 1. The calibration plate 7 is arranged between the beam body and the limiting member 6, and a calibration assembly for correcting the limiting member 6 to the vertical position is arranged on the calibration plate 7. The telescopic direction of the telescopic member 5 is the same as the extending direction of both ends of the limiting member 6. Specifically, the calibration plate 7 is preferably in the shape of a rectangular plate; a plurality of holes for the pipe body 1 to penetrate are arranged on the calibration plate 7; and the holes correspond to the through holes on the beam body; when the multiple pipe bodies 1 are arranged at the same horizontal height, the calibration plate 7 sleeved on the multiple pipe bodies 1 is also in a horizontal state; the setting of the calibration assembly corrects the limiting member 6 to the vertical position, which also limits the possibility of the pipe body 1 rotating. Then, by the telescopic direction of the telescopic member ⑤ being the same as the extending direction of both ends of the limiting member 6, the telescopic direction of the telescopic member 5 corresponds to the vertical lifting direction, that is, ensuring that the support assembly vertically supports the support plate 3, then supporting the square timber, and the support assemblies on the multiple pipe bodies 1 are all in a vertically supporting state, which can ensure that the square timber is horizontal, making the upper end surface of the square timber easy to be parallel and coplanar with the upper end surface of the beam body, and also facilitating the height adjustment and correspondence of the multiple support assemblies.

[0040] As a further preferred technical solution of this embodiment, the calibration assembly includes a calibration member 8 arranged on the calibration plate 7, and the limiting member 6 slides through the calibration member 8. Specifically, the calibration member 8 is vertically located directly above the axis of the pipe body 1; the limiting member 6 penetrates through the calibration member 8 and the pipe body 1 in sequence, so that the limiting member can be restricted to the vertical position, and the rotation of the pipe body 1 relative to the beam body is restricted.

[0041] As a further preferred technical solution of this embodiment, the calibration assembly includes a chute 9 provided on the calibration plate 7. The chute 9 includes a calibration section corresponding to directly above the axis of the pipe body 1 and a rotating section arranged around the axis of the pipe body 1. A sliding column 10 slidably connected to the chute 9 is connected to the calibration member 8. Specifically, the chute 9 consists of two sections, namely a calibration section and a rotating section. The upper end of the calibration section of the chute 9 communicates with one end of the rotating section. The rotating section of the chute 9 is arc-shaped with the axis of the through hole formed on the beam body as the center of the circle. The sliding column 10 is preferably cylindrical and can slide arbitrarily within the trajectory defined by the chute 9. When the sliding column 10 slides within the calibration section of the chute 9, it drives the calibration member 8 to move closer to or away from the axis of the pipe body 1. At this time, the calibration member 8 moves up and down directly above the axis of the pipe body 1, so as to keep the limiting member 6 passing through the calibration member 8 vertical. Moreover, when the sliding column 10 moves towards the lower end of the calibration section of the chute 9, the sliding column 10 moves away from the rotating section, and thus the calibration member 8 will not rotate around the pipe body 1. When the sliding column 10 slides within the rotating section, it drives the pipe body 1 to rotate through the calibration member 8 and the limiting member 6 that passes through the calibration member 8 and the pipe body 1. The rotation of the pipe body 1 drives the support plate 3 fixedly installed thereon to rotate, and the support plate 3 rotates to lower its height, which can further promote the separation of the square timber from the floor slab and facilitate the disassembly of the square timber.

[0042] As a further preferred technical solution of this embodiment, the calibration assembly includes a movable groove 11 set in the calibration plate 7, a ring sleeve 12 is rotatably set in the movable groove 11, a guide rod 13 is set on the ring sleeve 12, and a guide sleeve 14 is set on the guide rod 13. The guide sleeve 14 is fixedly connected to the sliding column 10. Specifically, the ring sleeve 12 is coaxial with the tube body 1, and the ring sleeve 12 rotates only in the movable groove 11; the axis of the guide rod 13 intersects the axis of the ring sleeve 12 perpendicularly; the guide rod 13 rotates in the movable groove 11 with the ring sleeve 12; the guide sleeve 14 rotates along the guide rod 1 3 slides toward or away from the axis of the ring sleeve 12; one end of the guide sleeve 14 is connected to one end of the guide rod 13 via the first spring 23. The provision of the first spring 23 enables the guide sleeve 14 to remain on the guide rod 13 at the end away from the axis of the ring sleeve 12, thereby keeping the slide post 10 in the rotation section corresponding to the slide groove 9; and when the slide post 10 moves toward the lower end of the calibration section of the slide groove 9, the guide sleeve 14 moves on the guide rod 13 and elastically deforms the first spring 23. Due to the position of the slide post 10 at this time, the ring sleeve 12 cannot continue to rotate. In actual use of this technical solution, when the limiting member 6 of the bolt is connected to the calibration member 8 and is in a vertical position, the nut is connected to the tail end and tightened to drive the calibration member 8 close to the outer surface of the tube body 1, and the calibration member 8 drives the slide post 10 to move to the lower end of the calibration section of the slide groove 9, and the slide post 10 drives the guide sleeve 14 to move on the guide rod 13 to elastically deform the first spring 23 and store elastic potential energy. At this time, the ring sleeve 12 cannot rotate, thereby smoothly positioning the limiting member 6 in the vertical position, and then Then, after the concrete of the floor slab is cast and shaped, when the square timber needs to be removed, the nut at the tail end of the limiter 6, which is preferably a bolt, can be removed first. The elastic potential energy of the first spring 23 is released, pushing the guide sleeve 14, and the guide sleeve 14 drives the slide post 10 to move to the rotating section of the corresponding slide groove 9. At this time, the tube body 1 can be rotated to lower the height of the support plate 3, and the slide post 10 slides in the rotating section of the slide groove 9, and the ring sleeve 12 rotates in the movable groove 11; after the height of the support plate 3 is lowered, the square timber leaves the floor slab and can be easily disassembled.

[0043] As a further preferred technical solution of this embodiment, a spirit level 15 is rotatably mounted on the calibration plate 7. The rotation of the spirit level 15 is linked to the rotation of the tube body 1. Specifically, a first gear 24 is rotatably mounted within the calibration plate 7, and the spirit level 15 is coaxially and fixedly connected to the first gear 24. A second gear 25 is coaxially and fixedly mounted on one end of the ring sleeve 12, and the first and second gears 24 and 25 are connected by a rack 26. When the rotation of the ring sleeve 12 is restricted by the slide post 10 being within the calibration section of the chute 9, the spirit level 15 maintains a synchronous horizontal state with the calibration plate 7. That is, after the vertical position of the limiter 6 is calibrated, the spirit level 15 can detect the horizontal state of the calibration plate 7. In addition, under the linkage of the first gear 24, the second gear 25, and the rack 26, multiple ring sleeves 12 rotate synchronously, thereby achieving the synchronous rotation of multiple tube bodies 1, thereby simultaneously lowering the height of multiple support points of the square timber, ensuring that the square timber leaves the floor smoothly.

[0044] In another embodiment proposed by the present invention, a key body 16 is provided on the inner wall of the quick-release member 2, and a key groove 17 matching the key body 16 is provided on the outer wall of the end of the pipe body 1. Specifically, after the quick-release member 2 is installed on the pipe body 1, the support assembly remains vertical, so that the key body 16 is correspondingly directly below the support assembly, and the key groove 17 is directly corresponding to the upper end of the limiting member 6 along the axial direction of the pipe body 1; the setting of the key body 16 and the key groove 17 limits the relative rotation between the quick-release member 2 and the end of the pipe body 1, and determines that the telescopic direction of the telescopic member 5 in the support assembly is consistent with the extending directions of both ends of the limiting member 6.

[0045] As a preferred technical solution of this embodiment, a clamping rod 18 is movably provided at the outermost end of the key groove 17, and the movement of the clamping rod 18 is linked with the rotation of the pipe body 1 through a linkage assembly provided in the pipe body 1. Specifically, the outermost end of the key groove 17 extends to the end of the pipe body 1, that is, the key body 16 can slide out of the key groove 17 towards the end of the pipe body 1. Under this condition, the quick-release member 2 can be sleeved on the end of the pipe body 1 to automatically fix the position without being tightened; the clamping rod 18 restricts the movement of the key body 16 by blocking at the outermost end of the key groove 17, that is, restricts the quick-release member 2 from leaving the end of the pipe body 1; a connecting sleeve 27 is provided on the inner wall of the end of the pipe body 1, and the clamping rod 18 movably penetrates through the connecting sleeve 27. The connecting sleeve 27 guides the clamping rod 18, and the direction is perpendicular to the axial direction of the pipe body 1; the end of the clamping rod 18 extending into the key groove 17 can be movably retracted into the connecting sleeve 27 to leave the key groove 17, thereby restoring the smoothness of the outermost end of the key groove 17.

[0046] As a preferred technical solution of this embodiment, the linkage assembly includes a trigger rod 19 that slidably penetrates the wall of the pipe body 1. One end of the trigger rod 19 abuts against the inner wall of the hole on the calibration plate 7 through which the pipe body 1 passes. A groove 20 matching the trigger rod 19 is provided on the inner wall of the hole. The other end of the trigger rod 19 is connected to the latch rod 18 through a lever frame 21 rotatably connected inside the pipe body 1. Specifically, the trigger rod 19 and the latch rod 18 are parallel to each other. A spring sleeve 28 is provided on the inner wall of the pipe body 1. The trigger rod 19 slidably penetrates the spring sleeve 28, and a convex ring 29 movably connected inside the spring sleeve 28 is provided on the trigger rod 19. A second spring 30 is connected between the convex ring 29 and the inner wall of the spring sleeve 28. The setting of the second spring 30 enables the trigger rod 19 to keep one end penetrating and extending out of the outer wall of the pipe body 1 without being affected by external forces. Both ends of the groove 20 penetrate the calibration plate 7. When the sliding column 10 slides to the end far from the calibration section on the rotating section in the sliding groove 9, the trigger rod 19 corresponds to the groove 20. Both ends of the lever frame 21 are slidably connected with live pins 31, and the two live pins 31 are respectively fixedly connected to the latch rod 18 and the trigger rod 19. The lever frame 21 is arranged to avoid the limiting member 6. In the actual use of this technical solution, the trigger rod 19 can elastically contract into the pipe body 1, thus not affecting the pipe body 1 passing through the beam body. At this time, the second spring 30 undergoes elastic deformation and stores elastic potential energy. When the quick-release member 2 needs to be disassembled, first cancel the fixed connection between the limiting member 6 and the pipe body 1 according to the above principle process, move the calibration member 8 upward, drive the sliding column 10 to correspond to the rotating section of the sliding groove 9, and then rotate the pipe body 1 to drive the quick-release member 2, the support assembly and the support plate 3 to rotate, thereby reducing the height of the support plate 3, moving the square timber downward away from the floor slab and forming enough space under the floor slab to facilitate the removal of the square timber. At the same time, as the pipe body 1 rotates, the pipe body 1 drives the sliding column 10 to slide on the rotating section of the sliding groove 9 away from the calibration section through the limiting member 6 and the calibration member 8. When the sliding column 10 moves to the end far from the calibration section on the rotating section, the trigger rod 19 corresponds to the groove 20, then the second spring 30 releases its elastic potential energy to enable the trigger rod 19 to extend out of the outer wall of the pipe body 1 and embed into the groove 20. At the same time, the trigger rod 19 drives the latch rod 18 to move downward through the lever frame 21 to avoid the outermost end of the key groove 17. Thus, the quick-release member 2 can be directly quickly removed axially outward along the pipe body 1 without loosening or tightening the quick-release member 2, thereby greatly improving the disassembly efficiency.

[0047] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
