DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0035] Example 1: Reference Figures 1-15 A floor-embedded detachable edge protection system includes: an embedded upright base system 1, a scaffolding system 3, a protective net 35 and a sheet metal 4. Multiple sheet metals 4 are fixed on the floor, and each sheet metal 4 is connected to the top of an embedded upright base system 1. A vertical pole 31 in the scaffolding system 3 is inserted on the top of the embedded upright base system 1. Two adjacent vertical poles 31 are connected by a protective net 35. The end face of the vertical pole 31 facing the edge of the floor is connected to the sheet metal 4 through an embedded inclined base system 2.

[0036] The principles of the above scheme are:

[0037] Before carrying out edge construction, multiple sheet metals 4 are fixed parallely and equidistantly on the top of the floor slab using steel bars, and are set perpendicular to the edge of the floor slab. Then, the embedded upright base system 1 is connected to the sheet metal 4, and the scaffolding system 3 is inserted on the top of the embedded upright base system 1. A protective net 35 is connected to the two vertical poles 31. The embedded inclined base system 2 is connected to the end face of the vertical pole 31 facing the edge of the floor slab to complete the fixation of the entire device. Then, construction is started. When the construction is completed, the scaffolding system 3 is removed from the top of the embedded upright base system 1, and the connection between the scaffolding system 3 and the embedded inclined base system 2 is released.

[0038] The beneficial effects of the above scheme are:

[0039] The device uses an embedded upright base system 1 on the floor slab to insert a vertical pole 31 of the scaffolding system 3, and uses a protective net 35 on the vertical pole 31 to protect personnel and equipment performing edge construction, thereby avoiding external force on the support system under the slab and improving safety during construction.

[0040] The plug-in cooperation between the embedded upright base system 1 and the upright pole 31 improves the efficiency of the installation, disassembly and transportation of the device, and reduces the capital cost invested in production;

[0041] The support of the vertical rod 31 by the embedded inclined base system 2 further improves the overall stability of the device;

[0042] Since the function of the device is to provide edge protection before the floor slab is poured with concrete, and the sheet metal 4 is fixed to the floor slab through steel bars, after the construction is completed, the upright base system 1, the inclined base system 2 and the sheet metal 4 are poured into the concrete, and can be connected to formal protective devices such as guardrails through the upright base system 1 and the inclined base system 2 to be used as a new protective device. First, the setting of the upright base system 1, the inclined base system 2 and the sheet metal 4 as the basic mechanism can not only facilitate the installation of the scaffolding system 3 and the protective net 35 for temporary protection, but also can The basic components used for the new protective device improve the functional diversity of the device when in use and avoid the removal of the sheet metal 4 on the floor slab, which not only reduces the labor intensity of workers but also avoids accidental damage to the floor slab. In addition, the upright base system 1 and the inclined base system 2 can be used as a reference for the pouring thickness of the floor slab concrete, which is convenient for improving the quality of construction and improving construction efficiency. In addition, after the upright base system 1, the inclined base system 2 and the sheet metal 4 as metal components are poured into the concrete of the floor slab, it is convenient to increase the structural strength of the floor slab and further improve the construction quality.

[0043] Example 2: Reference Figures 1-15The two adjacent vertical poles 31 are connected by a cross bar 32, and the cross bar 32 is set between the protective net 35 and the edge of the floor.

[0044] The principles and beneficial effects of the above scheme are:

[0045] The two vertical rods 31 are connected to the horizontal rod 32, which further increases the structural strength of the device, so that it will not be deformed after transportation and installation.

[0046] Example 3: Reference Figures 1-15 The two adjacent vertical poles 31 are connected by a footboard 34, and the footboard 34 is set between the protective net 35 and the edge of the floor.

[0047] The principles and beneficial effects of the above scheme are:

[0048] Two adjacent uprights 31 are connected by a toe plate 34. The provision of the toe plate 34 facilitates the operator to identify which side of the device faces the edge of the floor slab and to install the embedded inclined base system 2, thereby reducing the probability of errors during installation and improving the efficiency of installation and removal of the device.

[0049] Example 4: Reference Figures 1-15 The embedded upright base system 1 includes: a base plate 11, a screw 12, a round rod 13, a limit plate 14, a threaded sleeve 15 and a plastic sleeve protective cover 16. A base plate 11 is placed on each of the sheet metals 4, and a screw 12 is connected to the base plate 11. The screw 12 is connected to the sheet metal 4 through a fixing part. The screw 12 is threadedly connected to the bottom of the threaded sleeve 15, and the top of the threaded sleeve 15 is connected to the round rod 13. The round rod 13 is inserted into the circular hole at the bottom of the vertical rod 31. The top of the limit plate 14 on the round rod 13 contacts and cooperates with the bottom of the vertical rod 31. The threaded sleeve 15 is covered with a plastic sleeve protective cover 16.

[0050] The principles and beneficial effects of the above scheme are:

[0051] After the sheet metal 4 is fixed on the floor, a base plate 11 is placed on the top of each sheet metal 4. The top of the base plate 11 is connected to a screw rod 12. The screw rod 12 is connected to the sheet metal 4 through a fixing piece. When the vertical rod 31 needs to be installed, the threaded sleeve 15 is threadedly connected to the screw rod 12 to further complete the installation of the round rod 13. Then, the round hole at the bottom of the vertical rod 31 is plugged into the round rod 13. The bottom of the vertical rod 31 contacts and cooperates with the limiting plate 14 on the round rod 13 to complete the installation of the vertical rod 31. The arrangement of the round hole and the limiting plate 14 improves the stability of the vertical rod 31 after installation.

[0052] After the use of the device is completed, the connection between the round hole and the round rod 13 is completed, that is, the vertical pole 31 and the protective net 35 are removed and transported to the next work station to perform new edge protection preparations. At this time, the top opening of the plastic sleeve protective cover 16 installed on the threaded sleeve 15 is adjusted to be higher than the top setting of the threaded sleeve 15, and then the cement is poured on the floor slab, and it is ensured that the top opening of the plastic sleeve protective cover 16 is higher than the height of the cement. After the cement is dry, the round rod 13 is rotated to complete the threaded connection between the threaded sleeve 15 and the screw 12. The plastic sleeve protective cover 16 can protect the threaded sleeve 15 before the cement dries to prevent the cement from solidifying on the threaded sleeve 15, reduce the difficulty of cleaning the threaded sleeve 15, and at the same time avoid the occurrence of rust on the threaded sleeve 15 due to the presence of moisture in the cement, thereby extending the service life of the parts.

[0053] Example 5: Reference Figures 1-15 The embedded inclined base system 2 includes: a bottom plate 21, an inclined screw 22, an inclined round rod 23, an inclined limit plate 24, an inclined threaded sleeve 25 and an inclined plastic sleeve protective cover 26. A bottom plate 21 is placed on every three sheet metals 4. The bottom plate 21 is arranged between the cross bar 32 and the edge of the floor slab. The bottom of the inclined screw 22 is connected to the bottom of the bottom plate 21. The inclined screw 22 is connected to the sheet metal 4 through another fixing part. The top of the inclined screw 22 is threadedly connected to the bottom of the inclined threaded sleeve 25. The top of the oblique threaded sleeve 25 is connected to the bottom of the oblique round rod 23. The oblique round rod 23 is plugged into the second round hole at the bottom of the oblique rod 33. The top of the oblique rod 33 is connected to the vertical rod 31. The bottom of the oblique rod 33 contacts and cooperates with the top surface of the oblique limit plate 24. The oblique limit plate 24 is connected to the oblique round rod 23.

[0054] The principles and beneficial effects of the above scheme are:

[0055] After the protection net 35 is installed, the bottom plate 21 is placed on the sheet metal 4. The two adjacent sheet metals 4 form a span, and a bottom plate 21 is placed every three spans. This not only ensures that the bottom plate 21 has sufficient supporting force after installation, but also reduces the number of bottom plates 21 set up, which is beneficial to reducing the investment of funds when performing edge protection and saving production costs; another fixing part on the inclined screw 22 is used to connect with the sheet metal 4, and then the inclined threaded sleeve 25 is threadedly connected to the inclined screw 22, and the inclined round rod 23 is plugged into the round hole 2 of the inclined rod 33. The bottom of the inclined rod 33 is in contact with the inclined limit plate 24 of the inclined round rod 23, and then the top of the inclined rod 33 is connected to the vertical rod 31 to complete the support for the vertical rod 31, further improving the stability of the device during use, preventing the device from overturning due to strong winds or impact of objects, and improving the safety of the device during protection.

[0056] Example 6: Reference Figures 1-15The acute angle between the oblique rod 33 and the vertical rod 31 is 45°-60°.

[0057] The principles and beneficial effects of the above scheme are:

[0058] Setting the acute angle between the diagonal rod 33 and the vertical rod 31 to be between 45° and 60° not only helps to fully exert the supporting effect of the diagonal rod 33 on the vertical rod 31, but also reduces the area of ​​the floor occupied by the device, providing convenience for construction.

[0059] Example 7: Reference Figures 1-15 The fixing member includes: a mounting plate 5, a bottom plate 51, a longitudinal tube 52, a transverse tube 53, a push rod 54 and a spiral groove 55. The screw 12 and the oblique screw 22 are respectively connected to a mounting plate 5, each mounting plate 5 is connected to a bottom plate 51, and two longitudinal tubes 52 are connected to the bottom plate 51. The side wall of each longitudinal tube 52 is connected to the end of a transverse tube 53. The other ends of the two transverse tubes 53 are arranged opposite to each other. A push rod 54 is slidably connected in the transverse tube 53. The end of the push rod 54 It is provided with an arc surface, which is coplanar with the inner wall of the longitudinal tube 52 and is arranged toward the spiral groove 55. The middle part of the fire wire is connected to the sheet metal 4, and the two ends of the fire wire are respectively inserted into a horizontal tube 53. The arc surface cooperates with the inner wall of the longitudinal tube 52 to clamp the ends of the fire wire. The spiral groove 55 is longitudinally opened on the inner wall of the longitudinal tube 52. The side wall of the horizontal tube 53 is connected to the end of the spring 56. The other end of the spring 56 is set away from the horizontal tube 53 and is connected to the mounting ring on the side wall of the push rod 54.

[0060] The principles and beneficial effects of the above scheme are:

[0061] The screw rod 12 and the oblique screw rod 22 are respectively provided with a mounting plate 5. When the screw rod 12 and the oblique screw rod 22 need to be fixed, the middle part of the burning wire is first connected to the sheet metal 4. The burning wire is specifically a steel wire rope. Then, the two ends of the burning wire are respectively inserted into a longitudinal tube 52. The two push rods 54 are moved in opposite directions. Under the guidance of the transverse tube 53, the arc surface of the end of the push rod 54 toward the spiral groove 55 contacts one side of the burning wire. After continuing to apply thrust to the push rod 54, The other side of the burnt wire contacts the spiral groove 55, and the longitudinal tube 52 and the transverse tube 53 cooperate to clamp the end of the burnt wire. The spiral groove 55 provided in the longitudinal tube 52 can increase the friction between the end of the burnt wire and the longitudinal tube 52, further preventing the end of the burnt wire from falling out of the longitudinal tube 52. After the two ends of the burnt wire are fixed, the screw 12 and the oblique screw 22 are fixed, further achieving the fixation of the bottom plate 11 and the bottom plate 21 on the sheet metal 4.

[0062] When the push rod 54 is pushed into the interior of the longitudinal tube 52, the spring 56 is compressed. When the device is in the non-operating state, the spring 56 on the push rod mounting ring 54 can limit the position of the push rod 54 in the transverse tube 53, preventing the arc surface of the push rod 54 from penetrating into the interior of the tube 52 and being unable to be moved out when the device is moved. At the same time, since the arc surface is coplanar with the inner wall of the longitudinal tube 52, there is no need to adjust the position of the arc surface before clamping for fire wires of different diameters, and thus there is no need to deliberately move the push rod 54, so that the arc surface clears the end of the fire wire, thereby avoiding contact between the parts and the end of the fire wire, thereby preventing the end of the fire wire from colliding with the internal parts of the device and becoming scattered and unable to be clamped smoothly, and also preventing the end of the fire wire from contacting the push rod 54 and erroneously judging that the clamping is completed when there is no clamping, thereby avoiding the phenomenon that the bottom plate 11 and the bottom plate 21 are not successfully fixed on the sheet metal 4, thereby avoiding the safety accident of the device disintegrating when performing edge protection.

[0063] During the process of inserting the end of the fire wire into the interior of the longitudinal tube 52, the spiral groove 55 can contact and rub against the end side wall of the fire wire. When there is rust on it, it can be removed by the friction of the spiral groove 55, thereby increasing the clamping force applied by the device when clamping the end of the fire wire.

[0064] Example 8: Reference Figures 1-15 The other end of the push rod 54 away from the cross tube 53 is connected to the side wall of the thrust arc 57. A chamfer 58 is provided at the top of the inner wall of the thrust arc 57. The chamfer 58 is arranged toward the second chamfer 61. The second chamfer 61 is arranged at the bottom of the cylinder 60. The cylinder 60 is arranged above the thrust arc 57. The cylinder 60 is coaxially connected to the second cylinder 62. The side wall of the second cylinder 62 is connected to the base plate 51 through the second spring 63. The sleeve 64 connected to the side wall of the second cylinder 62 is slidably matched with the top of the guide column 65. The bottom of the guide column 65 is connected to the base plate 51.

[0065] The principles and beneficial effects of the above scheme are:

[0066] It is necessary to move the push rod 54 toward the inside of the longitudinal tube 52, and the downward movement of the second cylinder 62 drives the cylinder 60 to move synchronously. When the second chamfer 61 contacts the chamfer 58, the thrust arc 57 is pushed to move, and the movement of the thrust arc 57 drives the movement of the push rod 54. The second spring 63 provides an upward elastic force for the second cylinder 62 when the device is not in use to prevent the second chamfer 61 thereon from contacting the chamfer 58, which would cause the push rod 54 to malfunction. When the second cylinder 62 moves downward, the guide column 65 on the bottom plate 51 slides with the sleeve 64 on the second cylinder 62 to provide guidance for the smooth downward movement of the second cylinder 62.

[0067] Example 9: Reference Figures 1-15The side wall of the second cylinder 62 is longitudinally provided with multiple locking blocks 66, and the chamfer three 67 at the bottom of the locking block 66 is set toward the chamfer four 68, and the chamfer four 68 is set at the end of the second locking block 69. The second locking block 69 is slidably connected to the base plate 51 through the optical axis, and the second locking block 69 is connected to the base plate 51 through the spring three 691.

[0068] The principles and beneficial effects of the above scheme are:

[0069] When the second cylinder 62 moves downward, it needs to be locked to prevent it from resetting under the elastic force of the second spring 63. As the second cylinder 62 moves downward, the locking block 66 moves synchronously. After the chamfered corner 3 67 at the bottom of the locking block 66 and the chamfered corner 4 68 frictionally cooperate, the locking block 2 69 moves away from the second cylinder 62 under the sliding cooperation between the bottom plate 51 and the optical axis. At the same time, the spring 3 691 is compressed, and after ending the contact and cooperation with the locking block 66, under the elastic force of the spring 3 691, the locking block 2 69 is reset and uses its bottom to contact and cooperate with the top of the locking block 66 to prevent it from resetting, thereby preventing the second cylinder 62 from resetting, thereby improving the stability of the device after the fire-burning wire is clamped, and further preventing the fire-burning wire from falling out of the device.

[0070] Since a plurality of locking blocks 66 are longitudinally and equidistantly arranged on the side wall of the second cylinder 62, the mechanism can lock the burning wires of different diameters.

[0071] Example 10: Reference Figures 1-15 The push rod 54 is connected to the piston 71 through the connecting rod 70. The connecting rod 70 and the end of the liquid storage tank 72 are slidably sealed. The piston 71 and the liquid storage tank 72 are slidably sealed. The other end of the liquid storage tank 72 is connected to the end of the pipe 73. The other end of the pipe 73 penetrates into the interior of the longitudinal tube 52. The end face of the piston 71 facing the longitudinal tube 52 and the inner wall of the liquid storage tank 72 store metal glue. A one-way valve is installed in the pipe 73.

[0072] The principles and beneficial effects of the above scheme are:

[0073] While the push rod 54 is clamping the end of the fire wire, the connecting rod 70 drives the piston 71 to move synchronously. The piston 71 applies pressure to the metal glue inside the liquid storage tank 72. The metal glue is specifically epoxy resin glue, which is characterized by high strength, high temperature resistance, corrosion resistance and higher hardness after curing. As the piston 71 moves, the pressure of the metal glue increases. As the piston 71 continues to move, the metal glue in the pipe 73 passes through the one-way valve and enters the longitudinal pipe 52. Since the longitudinal pipe 52 is provided with a spiral groove 55, the metal glue can flow between the fire wire and the inner wall of the longitudinal pipe 52. Then, when the device completes the clamping of the fire wire, the metal glue bonds the longitudinal pipe 52, the spiral groove 55 and the fire wire, further ensuring the stability of the fire wire.

[0074] Since the fire wire itself has different diameters, when its diameter is large, the movement distance of the piston 71 is small, and the volume of metal glue discharged into the longitudinal tube 52 is small. The device can fully clamp the fire wire through the arc surface. At this time, the metal glue bonds to the bottom of the fire wire, helping to improve the stability of the fire wire in the longitudinal tube 52. When the diameter of the fire wire is small, the movement distance of the piston 71 is large, and the volume of metal glue discharged into the longitudinal tube 52 is large. Since the diameter of the fire wire is small at this time, although the arc surface can contact the fire wire, the clamping force is relatively reduced. The discharged metal glue can be used as an auxiliary means to bond the side wall of the fire wire and then fix it, thereby improving the ability of the device to work in different environments.

[0075] Example 11: Reference Figures 1-15 The middle part of the bottom plate 51 is connected to the tube body 511, the inner wall of the tube body 511 is rotatably connected to the side wall of the second tube body 512, the bottom of the second tube body 512 is connected to the top of the mounting plate 5, and the side wall of the second cylinder 62 is provided with a receiving groove 621. The inner wall of the bottom of the receiving groove 621 is rotatably connected to the end of the locking bar 622. The top surface of the locking bar 622 is connected to the inner wall of the top of the receiving groove 621 through a compression spring 623. The other end of the locking bar 622 is plugged into the longitudinal groove 624. The longitudinal groove 624 is provided on the inner wall of the tube body 511. The bottom of the locking bar 622 is plugged into the transverse groove 625. The transverse groove 625 is provided on the top surface of the second tube body 512.

[0076] The principles and beneficial effects of the above scheme are:

[0077] Before a downward force is applied to the second cylinder 62, the other end of the lock bar 622 engages with the longitudinal groove 624. The bottom of the lock bar 622 and the transverse groove 625, under the action of the elastic force of the compression spring 623, lock the tube body 511 and the second tube body 512 to prevent them from rotating relative to each other.

[0078] When the second cylinder 62 is pressed down without discharging the metal glue into the interior of the longitudinal tube 52, the locking bar 622 rotates relative to the second cylinder 62, and the other end of the locking bar 622 moves toward the interior of the receiving groove 621, while compressing the compression spring 623. The receiving groove 621 has enough space to accommodate the compressed compression spring 623 and the recovered locking bar 622. At this time, the relative locking of the tube body 511 and the second tube body 512 is completed, and the bottom plate 51 can be rotated relative to the mounting plate 5. Synchronously, the longitudinal tube 52 rotates relative to the screw 12 and the inclined screw 22, so that the relative position between the longitudinal tube 52 and the end of the fire-burning wire can be adjusted, thereby reducing the difficulty of clamping the fire-burning wire.

[0079] Example 12: Reference Figures 1-15The tube body 511 is placed on the side wall below the bottom plate 51 and is connected to a worm gear 75. The worm gear 75 is meshed with the worm 76, and the worm 76 is rotatably connected to the mounting plate 5. A bearing rod 513 is connected to the bottom plate 51, and the bearing rod 513 contacts and cooperates with the end side wall of the fire wire. The two ends of the fire wire are cross-arranged on both sides of the bearing rod 513. Two baffles 514 are coaxially slidably connected to the bearing rod 513. The two baffles 514 are connected by bolts 8. The baffles 514 are threadedly connected to the screw holes of the bearing rod 513 through bolts 81. Multiple screw holes are opened on the side wall of the bearing rod 513 along the length direction of the sheet metal 4. The bearing rod 513 is arranged above the second cylinder 62. The inner wall of the top of the longitudinal tube 52 is connected to the inner wall of the rubber ring 521, and the top opening of the longitudinal tube 52 is connected to the aluminum foil disk 522.

[0080] The principles and beneficial effects of the above scheme are:

[0081] After the middle part of the fire wire is connected to the sheet metal 4, it is located below the mounting plate 5. Since the cross section of the sheet metal 4 is U-shaped, after being connected to the sheet metal 4, the side walls of the two ends of the fire wire first contact the top of the two sides of the cross section of the sheet metal 4. Before the ends of the two fire wires are respectively inserted into a longitudinal tube 52, the two ends of the fire wire are cross-arranged, and the side walls of the end of the fire wire are in contact with the top of the bearing rod 513. After adjusting the two baffles 514 to clamp the side walls of the two ends of the fire wire, use the bolt 8 to fix the two baffles 514 together, and fix the bolt 2 81 to the bearing rod 513. The bearing rod 513 is located at the top of the cross section of the sheet metal 4 and the cylindrical The ends of the two fire wires are then plugged into the longitudinal tube 52. At this time, since the relative locking between the tube body 511 and the second tube body 512 is completed, the worm 76 can be rotated, and the worm 76 drives the worm gear 75 meshing with it to rotate, and the worm gear 75 drives the tube body 511 to rotate, thereby realizing the rotation of the bottom plate 51. At this time, the two baffles 514 can be understood as two fingertips for clamping the fire wire. The side walls of the two crossed fire wires begin to entangle under the contact of the bearing rod 513 and the restriction of the baffle 514, preventing the fire wire from loosening and further increasing the stability of the fire wire after connection.

[0082] The rubber ring 521 provided on the inner wall of the top of the longitudinal tube 52 reduces the diameter of the interior of the longitudinal tube 52. In the process of inserting the end of the fire-burning wire into the interior of the longitudinal tube 52, the aluminum foil disc 522 needs to be pierced first. The setting of the aluminum foil disc 522 can not only protect the interior of the longitudinal tube 52 and prevent external dust from accumulating in the tube parts, but also prevent the push rod 54 from rusting and the internal clamping force of the device from being unable to be applied. In addition, the opening in the middle of the pierced aluminum foil disc 52 faces downward, which cooperates with the fire-burning wire and the rubber ring 521 to protect the interior of the longitudinal tube 52 again, preventing the device from a sudden increase in the clamping force causing the metal glue output pressure to be too high and causing the metal glue to overflow, thereby avoiding the problem of metal glue adhering to the surface of the threaded sleeve 15 and the oblique threaded sleeve 25, or the threaded parts of the two, or the connection between the two and the screw 12 and the oblique screw 22, which will cause the appearance of reduced cleanliness and increased disassembly difficulty.

[0083] The meshing connection between the worm wheel 75 and the worm 76 can lock the rotated base plate 51 .
