Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a building support frame. Background Technology

[0002] When construction is required at heights within a building, scaffolding is often used for assistance. For example, in buildings such as hotels, bars, and banks with ceilings reaching five or six meters in height, ladders alone are insufficient to reach the required height when working on the ceiling. Therefore, scaffolding is often needed for workers to use. If the height needs to be increased further during construction, such as in the case of a stepped ceiling design where the height increases towards the center, workers often need to first dismantle and remove the platform from the scaffolding, then climb onto the side of the scaffolding to install the scaffolding poles to increase the height, and then reinstall the platform. This process is cumbersome and carries certain risks. Summary of the Invention

[0003] To address the cumbersome and potentially dangerous process of raising the height of a building support frame during construction, this application provides a building support frame.

[0004] This application provides a building support frame, which adopts the following technical solution:

[0005] A building support frame includes a platform for carrying workers and support poles for supporting the platform. Support poles for structural reinforcement are provided between the support poles. The platform has a clearance groove, through which the platform slides up and down on the support poles and the support poles. Support blocks for supporting the platform are telescopically provided on the support poles. A station plate for covering the opening of the clearance groove is slidably provided on the platform, and the station plate slides between adjacent support poles. The platform also has a control component for controlling the platform to move up and down on the support poles.

[0006] By adopting the above technical solution, the new frame poles and support poles are installed, and then the clearance slot is opened by sliding the station plate. At this time, the frame poles and support poles are both in the clearance slot. The platform plate is lifted by the control component. After the lifting is completed, the platform plate is supported by the support block, and then the station plate is closed to close the clearance slot. It is convenient and quick, and the staff can operate while standing on the platform plate, which greatly reduces the danger.

[0007] Optionally, the platform plate has a lifting groove, and the control component includes a lifting seat that is slidably disposed in the lifting groove. The lifting seat has a sliding groove for the station plate to slide in. The station plate pulls the lifting seat to rise and fall by abutting against the sliding groove. The side wall of the lifting seat is flush with the platform plate. After the station plate pulls the lifting seat up, it protrudes from the side wall of the platform plate.

[0008] By adopting the above technical solution, the lifting and lowering of the station plate is controlled by the lifting seat, thereby controlling the sliding limit of the station plate in the clearance groove and improving the stability of the station plate.

[0009] Optionally, the platform plate has a flat groove, and a control plate is rotatably mounted on the lifting seat. The side wall of the control plate abuts against the inner wall of the flat groove to limit rotation. When the lifting seat rises, the control plate is lifted out of the flat groove to release the rotation limit. A lifting gear is rotatably mounted on the control plate, and a plurality of lifting tooth grooves for meshing with the lifting gear are provided on the frame rod. The control plate rotates out to make the lifting gear mesh on the lifting tooth grooves.

[0010] By adopting the above technical solution, the rotation limit of the control plate is controlled by the lifting of the lifting seat. After the lifting seat is raised, the sliding limit of the station plate and the rotation limit of the control plate are released at the same time, which is convenient, quick and improves the linkage. The lifting gear is used to control the lifting of the platform plate on the frame.

[0011] Optionally, the station plate is provided with a plurality of control tooth grooves, and a trigger gear is rotatably arranged in the inner wall of the groove. The trigger gear meshes with the control tooth grooves, and a control gear is sleeved on the rotating shaft of the control plate. The trigger gear also meshes with the control gear.

[0012] By adopting the above technical solution, when the station plate slides away from the clearance groove, the control tooth groove drives the trigger gear and the control gear, thereby driving the control plate to rotate, realizing the linkage between the station plate and the control plate, improving the synchronization between the sliding of the station plate and the rotation of the control plate, and realizing that the control plate rotates into position at the same time as the station plate slides into position, which is convenient, fast and stable.

[0013] Optionally, the station plate is telescopically provided with a snap-fit ​​square rod, and the control plate rotation shaft is provided with a snap-fit ​​square groove for inserting the snap-fit ​​square rod to achieve snap-fit. The snap-fit ​​square rod is provided with abutting inclined surface for resisting and retracting the snap-fit ​​square rod into the station plate.

[0014] By adopting the above technical solution, when the station plate slides into position and drives the control plate to rotate into position, the locking rod is inserted into the locking slot. At this time, the sliding of the station plate and the rotation of the control plate are limited at the same time, which greatly improves the stability.

[0015] Optionally, the lifting gear rotating shaft is provided with at least two telescopic rods for rotating the lifting gear, and a plurality of the telescopic rods are distributed around the circumference of the lifting gear rotating shaft. The control plate is rotatably provided with a plug for inserting into the teeth of the lifting gear, and the control plate is provided with a stop rod for abutting the plug rod to limit the rotation of the plug rod.

[0016] By adopting the above technical solution, the lever arm length is extended by a telescopic rod, making it easier for workers to rotate the lifting gear. When the telescopic rod rotates to the point where it contacts the platform plate and cannot continue to rotate, the telescopic rod can be retracted. At the same time, workers can rotate the gear through another telescopic rod, which is convenient and saves effort. The insertion rod and the stop rod prevent the lifting gear from rotating in the opposite direction, thus improving safety.

[0017] Optionally, a limiting slider is slidably provided on the station plate, and a limiting groove is provided on the inner wall of the groove for the limiting slider to be inserted and slid in. A through hole is provided on the limiting slider for the snap-fit ​​rod to pass through and be inserted into the snap-fit ​​groove. The abutting inclined surface abuts against the limiting slider to guide the snap-fit ​​rod to retract into the station plate.

[0018] By adopting the above technical solution, when the station plate is located in the clearance groove, the limiting slider is positioned close to the lifting seat, and at this time, the limiting slider is also positioned close to the clearance groove within the limiting slide groove. When the station plate is completely away from the clearance groove, the limiting slider is again positioned close to the clearance groove, and at this time, the limiting slider is positioned far away from the clearance groove within the limiting slide groove. Through the sliding limiting slider, while keeping the size of the lifting seat unchanged, the station plate can slide a longer distance, or the size of the lifting seat can be greatly shortened while keeping the sliding distance of the station plate unchanged, thereby improving efficiency and reducing costs.

[0019] Optionally, a small plate is rotatably mounted on the platform plate, the small plate is located between adjacent frame rods, an arc rod is provided on the small plate, and an arc groove is provided on the station plate for the arc rod to be inserted and locked. A bottom plate is provided on the inner wall of the clearance groove to abut against the small plate and limit the rotation angle of the small plate.

[0020] By adopting the above technical solution, the sliding of the station plate is limited by a small plate, thereby improving stability.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Makes raising the platform height more convenient and faster.

[0023] 2. Workers can operate the equipment while standing on the platform, which greatly reduces the risk. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0033] This application discloses a building support frame. (Refer to...) Figure 1The building support frame includes a platform 1 for carrying workers and support rods 11 for supporting the platform 1. In this embodiment, the direction of gravity is downward, and the opposite direction is upward. In this embodiment, there are four support rods 11, and the length of the support rods 11 extends along the direction of gravity. Subsequent additions of support rods 11 simply increase the height by connecting them to these four support rods 11. The four support rods 11 are distributed at the four corners of a rectangle. Support rods 12 for structural reinforcement are fixedly connected between adjacent support rods 11 by bolts, and support rods 12 are also fixedly connected between diagonally distributed support rods 11. A clearance groove 13 is provided through the platform 1. The opening of the clearance groove 13 is rectangular, and all support rods 11 pass through the clearance groove 13. The four support rods 11 are distributed at the four corners of the clearance groove 13. The side walls of the support rods 11 are in contact with the inner walls of the clearance groove 13. The platform 1 slides and rises on the support rods 11 and support rods 12 through the clearance groove 13.

[0034] Reference Figure 1 and Figure 2 A support groove 142 is provided on the outer wall near the upper end of the support rod 11. A support block 14 slides within the support groove 142. The upper end face of the support block 14 is used to support and abut against the lower end face of the platform plate 1. A support spring 143 is installed within the support groove 142. One end of the support spring 143 abuts against the bottom wall of the support groove 142 facing its own opening, and the other end of the support spring 143 abuts against the end of the support block 14 located within the support groove 142. The support spring 143 extends and retracts in the direction that pushes the support block 14 out of the support groove 142. The diameter of the opening surface of the support groove 142 is smaller than the diameter of the middle section of the support groove 142, while the diameter of the end of the support block 14 located inside the support groove 142 is larger than the diameter of the end of the support block 14 located outside the support groove 142. This causes the end of the support block 14 located in the support groove 142 to abut against the inner wall of the periphery of the opening surface of the support groove 142, making it difficult for the support block 14 to slide completely out of the support groove 142. The end of the support block 14 located outside the support groove 142 is inclined, and the downward-facing sidewall of the support block 14 is inclined upward as it moves away from the support groove 142. Two station plates 2 slide on the platform plate 1 to cover the opening of the clearance groove 13. The station plates 2 slide between adjacent support rods 11 on the rectangular length side of the opening surface of the clearance groove 13, and each of the two station plates 2 slides on the two rectangular length sides of the opening surface of the clearance groove 13. A control component 3 for controlling the lifting and lowering of the platform plate 1 on the support rod 11 is also installed on the platform plate 1.

[0035] Reference Figure 3The platform plate 1 has a lifting groove 141, which includes a lifting bottom groove 144 and a lifting outlet groove 145. The lifting bottom groove 144 is located inside the platform plate 1 and is below the sliding direction of the station plate 2. The length direction of the lifting bottom groove 144 is parallel to the sliding direction of the station plate 2. One lifting bottom groove 144 is connected to two lifting outlet grooves 145. One end of the two lifting outlet grooves 145 is connected to both sides of the lifting bottom groove 144 in the length direction. The other end of the two lifting outlet grooves 145 extends upward to the upper surface of the platform plate 1 and is connected to the clearance groove 13. A locking block 146 is fixedly connected to the inner wall of the lifting outlet groove 145. The locking block 146 extends upward from the position of the lifting outlet groove 145 near the lifting bottom groove 144.

[0036] Reference Figure 4 The control component 3 includes a lifting seat 31 that slides and rises within the lifting groove 141. The lifting seat 31 includes a lifting base 311 and a lifting pull plate 312. Two lifting pull plates 312 are installed on one lifting base 311. The lifting base 311 moves up and down within the lifting groove 144. The thickness of the lifting base 311 is less than the height of the lifting groove 144. The length and width of the lifting base 311 are adapted to the length and width of the cross section of the lifting groove 144. The lifting pull plate 312 is fixedly connected to both sides of the lifting base 311 and slides within the lifting outlet groove 145. The lifting pull plate 312 can be pulled out of the lifting outlet groove 145.

[0037] Reference Figure 3 and Figure 4 and Figure 5 Two lifting plates 312 mounted on the same lifting base 311 have grooves 32 on their facing sidewalls for the station plate 2 to slide. The grooves 32 extend along the sliding direction of the station plate 2, and the height of the locking block 146 is lower than the height of the grooves 32, so that the station plate 2 can pass over the locking block 146 while the lifting plates 312 are limited by the locking block 146. The station plate 2 pulls the lifting base 311 and the lifting plates 312 to rise and fall by abutting against the upper and lower inner walls of the grooves 32. When the lifting base 311 is at its lowest point, the upper sidewall of the lifting plate 312 is flush with the upper surface of the platform plate 1. After the station plate 2 pulls the lifting plate 312 up, it protrudes from the sidewall of the platform plate 1.

[0038] Reference Figure 6The platform plate 1 has a flat groove 15, which is connected to the lifting outlet groove 145. A control plate 4 is rotatably mounted on the side wall of the lifting pull plate 312. The control plate 4 slides into and out of the flat groove 15. The control plate 4 is cuboid so that the outer side wall of the control plate 4 abuts against the inner wall of the flat groove 15 to limit the rotation of the control plate 4. When the lifting seat 31 rises, it lifts the control plate 4 out of the flat groove 15 to release the abutment and rotation limitation between the control plate 4 and the flat groove 15. A lifting gear 41 is rotatably connected to the side wall of the control plate 4. The frame rod 11 has several lifting tooth grooves 42 for meshing with the lifting gear 41. The lifting tooth grooves 42 are evenly distributed along the length of the frame rod 11. The control plate 4 rotates out so that the lifting gear 41 meshes with the lifting tooth grooves 42.

[0039] Reference Figure 5 and Figure 6 The station plate 2 has several control slots 21, which are evenly distributed along the sliding direction of the station plate 2. The control slots 21 are located in the sliding grooves 32. A trigger gear 22 is embedded in the inner wall of the sliding groove 32 and meshes with the control slots 21. A control gear 23 is sleeved on the rotating shaft of the control plate 4 and is embedded in the lifting plate 312. The trigger gear 22 also meshes with the control gear 23.

[0040] Reference Figure 3 and Figure 5 and Figure 7 The station plate 2 slides on the side wall of the slide groove 32 and has a square slide groove 241. A snap-fit ​​square rod 24 slides in the square slide groove 241 and a locking spring 242 is installed in the square slide groove 241. One end of the locking spring 242 abuts against the bottom wall of the square slide groove 241 facing its own opening, and the other end of the locking spring 242 abuts against the end of the snap-fit ​​square rod 24 that is inserted into the square slide groove 241. The locking spring 242 extends and retracts in the direction that pushes the snap-fit ​​square rod 24 out of the square slide groove 241. A snap-fit ​​square groove 25 is provided through the rotating shaft of the control plate 4 for inserting the snap-fit ​​square rod 24 to achieve snap-fit. In this embodiment, the square sliding groove 241 and the snap-fit ​​square groove 25 are both square in cross-section and have the same shape. The snap-fit ​​square rod 24 has abutting inclined surfaces 26 formed on the side walls facing away from the relief groove 13 and facing the relief groove 13 to abut against and push the snap-fit ​​square rod 24 into the station plate 2. The abutting inclined surface 26 formed on the side facing away from the relief groove 13 is inclined in a direction that gets closer to the relief groove 13 the further away from the square sliding groove 241 it is. The abutting inclined surface 26 formed on the side facing the relief groove 13 is inclined in a direction that gets further away from the square sliding groove 241 it is.

[0041] Reference Figure 6At least two telescopic rods 43 for rotating the lifting gear 41 are installed on its rotating shaft. In this embodiment, the telescopic rods 43 can be sleeve rods, which may include a hollow large rod, a middle rod, and a small rod, with the cross-sectional diameters decreasing sequentially. The middle rod is slidably fitted outside the small rod, and the large rod is slidably fitted outside the middle rod. The two telescopic rods 43 are stacked and distributed around the rotating shaft of the lifting gear 41. A plug rod 44 for inserting into the teeth of the lifting gear 41 is rotatably mounted on the control plate 4. A stop rod 45 for abutting the plug rod 44 to limit its rotation is fixedly connected to the control plate 4. An anti-reverse torsion spring 441 is fitted on the rotating shaft of the plug rod 44. One end of the anti-reverse torsion spring 441 is fixedly connected to the rotating shaft of the plug rod 44, and the other end is fixedly connected to the control plate 4 to reset the rotation of the plug rod 44.

[0042] Reference Figure 5 and Figure 7 Limiting sliders 5 slide on the two side walls of the station plate 2 in the sliding direction. The bottom wall of the slide groove 32 facing its own opening surface is provided with a limiting slide groove 51 for the limiting sliders 5 to be inserted and slide. The opening direction of the limiting slide groove 51 is parallel to the sliding direction of the station plate 2. The limiting slider 5 has a through hole 52 for the snap-fit ​​rod 24 to pass through and insert into the snap-fit ​​groove 25. The through hole 52 is perpendicular to the sliding direction of the limiting slider 5. The length of the abutting inclined surface 26 on the snap-fit ​​rod 24 is greater than the depth of the limiting slide groove 51. When the limiting slider 5 is difficult to continue sliding due to the contact with the inner wall of the end of the limiting slide groove 51, the station plate 2 continues to slide so that the end of the snap-fit ​​rod 24 extending into the limiting slide groove 51 contacts the limiting slider 5. At this time, the abutting inclined surface 26 contacts the limiting slider 5 and guides the snap-fit ​​rod 24 to retract into the station plate 2.

[0043] Reference Figure 1 Two small plates 6 rotate on the platform plate 1. The two small plates 6 are located at the two short sides of the opening of the rectangular clearance groove 13. The small plates 6 are located between adjacent support rods 11. Two arc rods 61 are fixedly connected to the small plates 6. Two arc grooves 62 are opened on the station plate 2 for the arc rods 61 to be inserted and locked. A bottom plate 63 is fixedly connected to the inner wall of the clearance groove 13 to abut against the small plates 6 and limit the rotation angle of the small plates 6. A groove 211 is opened on the station plate 2. The groove 211 is recessed to form a pull rod 212 for the user to pull.

[0044] The implementation principle of a building support frame in this application embodiment is as follows: When it is necessary to raise the height of the platform plate 1, firstly, a new frame rod 11 is fixedly connected to the original frame rod 11 with bolts, and then a support rod 12 is fixedly connected to the new frame rod 11 for structural reinforcement. Then, the small plate 6 is opened, and the platform plate 2 is lifted by the pull rod 212. Then, the platform plate 2 slides towards the opening of the clearance groove 13. When the platform plate 2 slides, the control tooth groove 21 drives the trigger gear 22 to rotate, and the trigger gear 22 drives the control gear 23 to rotate, thereby driving the control plate 4 to rotate so that the lifting gear 41 meshes with the lifting tooth groove 42. At this time, the snap-fit ​​square rod 24, the through hole 52, and the snap-fit ​​square groove 25 are aligned, so that the snap-fit ​​square rod 24 passes through the through hole 52 and is inserted into the snap-fit ​​square groove 25, so that the control plate 4 snaps and limits the rotation, and also limits the sliding of the platform plate 2. At this time, the lifting gear 41 is rotated by the telescopic rod 43 to drive the platform plate 1 to rise.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
