Description

Technical Field

[0001] This invention relates to a construction scaffold, specifically a construction scaffold. Background Technology

[0002] Construction scaffolding is a working platform erected to ensure the smooth progress of construction. Different types of construction projects use different types of scaffolding. Currently, when installing scaffolding, horizontal bars are generally connected to vertical bars. After the scaffolding is installed, safety nets need to be installed between adjacent horizontal bars. This process of installing safety nets piece by piece after the scaffolding is installed increases the workload for the workers. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a construction scaffold to solve the problems mentioned in the background art.

[0004] A construction scaffold includes uprights and horizontal bars. The horizontal bars are vertically arranged on the surface of the uprights. A disc is fixed to the outside of the uprights. A pair of connectors are symmetrically fixed at the left and right ends of the horizontal bars. The middle of the end of the connector near the disc has a socket for insertion into the disc. The crossbar is rotatably connected to a shaft, and a safety net is wrapped around the outside of the shaft. The end of the safety net passes through the bottom of the crossbar and is fixed with a connecting strip. The upper end of the crossbar has a connecting groove for inserting the connecting strip. Both the upper and lower ends of the connecting head have screw holes communicating with the insertion port. Inside the connecting head, on the side of the screw holes near the crossbar, there are an upper inner cavity, a middle inner cavity, and a lower inner cavity arranged sequentially from top to bottom. The left and right ends of the shaft pass through the two middle inner cavities and are fixed with inner ratchet wheels. The end of the inner ratchet wheel away from the shaft is fixed with a hexagonal groove. A rotating sleeve is rotatably connected inside the middle inner cavity and outside the inner ratchet wheel. The other end of the hexagonal groove is connected to the rotating sleeve. The movement is continuous. The upper part of the inner ratchet is connected to an inner pawl that is rotatably connected to the inner wall of the rotating sleeve. An outer ratchet is fixed on the outer side of the end of the rotating sleeve away from the shaft. An outer pawl that is rotatably connected to the inner wall of the middle inner cavity is connected above the outer ratchet. A transmission rod assembly one is installed on the lower side of the lower inner cavity. A locking block assembly that is pulsatorically connected to the transmission rod assembly one is installed at the top of the lower inner cavity. The locking block assembly is engaged with the surface of the rotating sleeve. A transmission rod assembly two is installed on the lower side of the upper inner cavity. Locking blocks one that are pulsatorically connected to the transmission rod assembly two are movably connected to the left and right ends of the inner wall of the connecting groove. Locking slots one that are inserted into locking blocks one are opened at both ends of the connecting strip.

[0005] Specifically, the outer wall of the rotating sleeve is uniformly connected with multiple rolling balls in a ring shape, and the inner wall of the inner cavity has an annular groove, in which the rolling balls are connected to the annular groove in a rolling manner.

[0006] Specifically, the transmission rod assembly includes a lower rotating shaft, a pull rod, a roller frame, and a lower roller. The lower rotating shaft is rotatably connected to the inner wall of the lower inner cavity. The roller frame is fixed on the side of the lower rotating shaft near the screw hole. The lower roller is rotatably connected to the other end of the roller frame. The pull rod is fixed on the side of the lower rotating shaft away from the screw hole.

[0007] Specifically, the locking block assembly includes a sleeve, a second locking block, a pull rope, and a spring. The sleeve is fixed to the top of the lower inner cavity, the second locking block is slidably connected inside the sleeve, the spring is connected between the lower part of the second locking block and the bottom of the sleeve, the pull rope is connected to the middle of the lower end of the second locking block, and the end of the pull rope passes through the bottom of the sleeve and is connected to the other end of the pull rod.

[0008] Specifically, the upper part of the second locking block moves through the inner cavity, and the outer wall of the rotating sleeve has multiple evenly spaced grooves in a ring shape. The upper part of the second locking block is inserted into one of the grooves.

[0009] Specifically, the transmission rod assembly two includes an upper rotating shaft, an L-shaped frame, an upper roller, and a connecting rod. The upper rotating shaft is rotatably connected to the interior of the upper inner cavity. The L-shaped frame is fixed outside the upper rotating shaft. The upper roller is rotatably connected to the long end of the L-shaped frame. The connecting rod is rotatably connected to the short end of the L-shaped frame.

[0010] Specifically, one end of the locking block is located inside the upper inner cavity, while the other end of the connecting rod is rotatably connected to the locking block.

[0011] Specifically, both ends of the connecting rod are fixed with convex shafts, and the two convex shafts respectively pass through the first locking block and the L-shaped frame.

[0012] Beneficial effects: During the installation of the uprights and crossbars, the bolts are screwed into the lower screw holes from bottom to top, and then stopped. At this point, the bolts push the lower roller, causing the pull rope to pull the second locking block downwards and no longer insert into the second locking slot. The connecting strip can then be pulled downwards, allowing the safety net to be unrolled from the outside of the shaft. The connecting strip will then be inserted into the connecting groove at the upper end of the lower crossbar. Then, the bolts are continued to be screwed into the upper screw holes. At this point, the bolts push the upper roller, causing the L-shaped frame to push the first locking block through the connecting rod. This causes the first locking block to insert into the first locking slot of the connecting strip, thus limiting the connecting strip inside the connecting groove. In this way, the safety net is installed simultaneously during the installation of the crossbars, which reduces the workload of the workers and shortens the construction period.

Implementation

[0015] like Figures 1 to 4 As shown, a construction scaffold includes uprights 1 and horizontal bars 3. The horizontal bars 3 are vertically arranged on the surface of the uprights 1. A disc 2 is fixed to the outside of the uprights 1. A pair of connectors 4 are symmetrically fixed at the left and right ends of the horizontal bars 3. The middle of the end of the connector 4 near the disc 2 has a socket 5 for insertion into the disc 2. When installing the uprights 1 and the horizontal bars 3, it is necessary to connect the connectors 4 of the horizontal bars 3 to the disc 2 of the uprights 1. During this process, the sockets 5 of the connectors 4 need to be inserted into the disc 2 accordingly. The crossbar 3 is rotatably connected to a shaft 8. A safety net 9 is wrapped around the outside of the shaft 8. The end of the safety net 9 passes through the bottom of the crossbar 3 and is fixed with a connecting strip 10. The upper end of the crossbar 3 has a connecting groove 7 for inserting into the connecting strip 10. The connector 4 has screw holes 6 at both the top and bottom ends that communicate with the insertion port 5. Inside the connector 4, on the side of the screw hole 6 near the crossbar 3, there are an upper inner cavity 29, a middle inner cavity 12, and a lower inner cavity 35 arranged sequentially from top to bottom. The left and right ends of the shaft 8 pass through... An inner ratchet 17 is inserted into and fixed inside the two inner cavities 12. A hexagonal groove 18 is fixed to one end of the inner ratchet 17 away from the shaft 8. A rotating sleeve 13 is rotatably connected inside the inner cavity 12 and outside the inner ratchet 17. Multiple balls 16 are evenly and circularly connected to the outer wall of the rotating sleeve 13. An annular groove is formed on the inner wall of the inner cavity 12, and the balls 16 are rotatably connected to the annular groove. The other end of the hexagonal groove 18 movably passes through the rotating sleeve 13. The upper part of the inner ratchet 17... An inner pawl 19 is connected to the inner wall of the rotating sleeve 13. An outer ratchet 14 is fixed to the outer side of the end of the rotating sleeve 13 away from the shaft 8. An outer pawl 15 is connected above the outer ratchet 14 and is rotatably connected to the inner wall of the inner cavity 12. When the safety net 9 is to be unrolled from outside the shaft 8, the shaft 8 rotates from front to back, and the shaft 8 will drive the inner ratchet 17 to rotate simultaneously. At this time, the inner ratchet 17 and the inner pawl 19 cooperate to drive the rotating sleeve 13 to rotate, and the rotating sleeve 13 carries... When the outer ratchet 14 rotates, the outer pawl 15 will not obstruct the rotation of the outer ratchet 14. When the shaft 8 needs to reel in the safety net 9, a hex wrench can be inserted into the hexagonal groove 18 and then the hexagonal groove 18 can be rotated. The hexagonal groove 18 will drive the inner ratchet 17 to rotate in the opposite direction. At this time, the inner pawl 19 will not obstruct the rotation of the inner ratchet 17. Therefore, the rotation of the inner ratchet 17 inside the rotating sleeve 13 will not drive the rotating sleeve 13 to rotate synchronously. In this way, the inner ratchet 17 drives the shaft 8 to rotate to reel in the safety net 9. A transmission rod assembly is installed on the lower side of the lower inner cavity 35. The transmission rod assembly includes a lower rotating shaft 21, a pull rod 22, a roller frame 23, and a lower roller 24. The lower rotating shaft 21 is rotatably connected to the inner wall of the lower inner cavity 35. The roller frame 23 is fixed on the side of the lower rotating shaft 21 near the screw hole 6. The lower roller 24 is rotatably connected to the other end of the roller frame 23. The pull rod 22 is fixed on the side of the lower rotating shaft 21 away from the screw hole 6. A locking block assembly that is pulsatorically connected to the transmission rod assembly is installed at the top of the lower inner cavity 35. The locking assembly includes a sleeve 25, a second locking block 26, a pull rope 27, and a spring 28. The sleeve 25 is fixed to the top of the lower inner cavity 35. The second locking block 26 is slidably connected inside the sleeve 25. The spring 28 is connected between the lower part of the second locking block 26 and the bottom of the sleeve 25. The pull rope 27 is connected to the middle of the lower end of the second locking block 26. The end of the pull rope 27 passes through the bottom of the sleeve 25 and is connected to the other end of the pull rod 22. The locking assembly is engaged with the surface of the rotating sleeve 13. The upper part of the second locking block 26 is movable through... Inside the inner cavity 12, the outer wall of the rotating sleeve 13 has multiple evenly spaced grooves 20 in a ring shape. The upper part of the locking block 26 is inserted into one of the grooves 20. During the installation of the upright 1 and the crossbar 3, the connector 4 needs to be inserted into the disc 2. Since the disc 2 also has a round hole on its upper outer side, the bolt is screwed into the lower screw hole 6 from bottom to top and then stopped. During this process, the bolt pushes the lower roller 24, which in turn drives the roller frame 23 to move. This causes the lower rotating shaft 21 to rotate, which in turn causes the pull rod 22 on the other side to move in the opposite direction. This causes the pull rod 22 to pull the pull rope 27, which in turn pulls the second locking block 26 inside the sleeve 25 to the compression spring 28. At this time, the second locking block 26 moves out of the second locking slot 20 and is no longer inserted inside the second locking slot 20. This allows the rotating sleeve 13 to rotate. At this time, the connecting strip 10 can be pulled down, so that the safety net 9 is unwound from the outside of the shaft 8. The connecting strip 10 will then be inserted into the connecting groove 7 at the upper end of the lower crossbar 3. A transmission rod assembly two is installed on the lower side inside the upper inner cavity 29. The left and right ends of the inner wall of the connecting groove 7 are movably connected to the transmission rod assembly two via locking blocks 34. The left and right ends of the connecting strip 10 are each provided with locking slots 11 for insertion into the locking blocks 34. The transmission rod assembly two includes an upper rotating shaft 30, an L-shaped frame 31, an upper roller 32, and a connecting rod 33. The upper rotating shaft 30 is rotatably connected to the interior of the upper inner cavity 29. The L-shaped frame 31 is fixed outside the upper rotating shaft 30. The upper roller 32 is rotatably connected to the long end of the L-shaped frame 31. The connecting rod 33 is rotatably connected to the short end of the L-shaped frame 31. One end of each locking block 34 is located inside the upper inner cavity 29, and the other end of the connecting rod 33 is rotatably connected to the locking block 34. Both ends of the connecting rod 33 are fixed with convex shafts, and the two convex shafts are respectively connected to the locking blocks. The L-shaped frame 31 and the connecting bar 34 are connected. After the connecting bar 10 is inserted into the connecting groove 7, the slot 11 of the connecting bar 10 will correspond to the locking block 34. Then, the bolt is tightened so that the bolt passes through the round hole of the disc 2 and is screwed into the upper screw hole 6. At this time, the bolt pushes the upper roller 32, which pushes the long end of the L-shaped frame 31. The L-shaped frame 31 rotates through the upper rotating shaft 30, so the short end of the L-shaped frame 31 moves and pushes the connecting rod 33. The connecting rod 33 pushes the locking block 34, so the locking block 34 will be inserted into the slot 11 of the connecting bar 10, thereby limiting the connecting bar 10 inside the connecting groove 7. In this way, the safety net 9 is installed at the same time during the installation of the crossbar 3, which reduces the workload of the workers. Because the scaffolding and safety net 9 can be installed quickly, the construction period can also be shortened.
