Description

Technical Field

[0002] In industrial or commercial buildings, holes are usually opened in the building floor for transporting raw materials or finished products, so as to achieve rapid transmission of materials within the building and improve production efficiency; at the same time, such holes can also be used for measuring and positioning building wiring, helping construction workers to accurately determine the location of building components and ensure construction quality and accuracy.

[0003] For the sake of safety during construction, when there is no need to transport materials or lay out wires, cover plates are usually used to block the openings to prevent construction workers from accidentally stepping into the openings during construction and causing safety hazards. If the openings are blocked directly with cover plates, when it is necessary to lay out wires or transfer materials, the cover plates need to be removed before laying out wires or transferring materials can be performed, and after the work is completed, the openings need to be blocked again with the cover plates. In the process of frequently removing and installing the cover plates, construction workers need to use tools to perform manual construction operations.

[0040] The present invention relates to a device for sealing a hole in a building floor slab and a construction method. Compared with a traditional sealing device, the device of the present invention is simple to operate and can greatly reduce the workload of construction personnel by driving a cover plate in an automated manner. When a floor slab hole needs to be sealed with concrete, the device of the present invention can also serve as a template to ensure the quality of sealing the floor slab hole.

[0041] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0042] A device for sealing a hole in a building floor, specifically, Figure 1 As shown, it includes a support plate 1, a sleeve 4, a lifting rod 5 and a cover plate 6. A driving device 2 is installed inside the support plate 1; the sleeve 4 is a hollow cylindrical structure, and its lower end is connected to the support plate 1; the lifting rod 5 is vertically and adjustably inserted into the sleeve 4, and its lower end passes through the sleeve 4 and the upper surface wall of the support plate 1 in turn, and is connected to the driving device 2; the cover plate 6 is connected to the upper end of the lifting rod 5.

[0043] In actual operation, the support plate 1 is placed above the floor opening to cover the floor opening; the driving device 2 is started to drive the lifting rod 5 to rotate and move upward, further driving the cover plate 6 to move upward, and when the cover plate 6 contacts the upper building floor, the driving device 2 is closed;

[0044] When removing the blocking device, the driving device 2 is operated in reverse to make the lifting rod 5 rotate in the opposite direction and move downward, further driving the cover plate 6 to move downward, so that the cover plate 6 gradually moves away from the upper building floor, and finally the blocking device can be removed.

[0045] In some embodiments, Figure 4As shown, the above-mentioned driving device 2 is optimized. In this embodiment, the driving device 2 includes a power supply 11, a first motor 8, a rotating rod 9, a second gear 10, a first gear 7 and a threaded screw 3. The power supply 11 is electrically connected to the first motor 8; the output end of the first motor 8 is connected to the rotating rod 9; the rotating rod 9 is connected to the second gear 10; the second gear 10 is meshed with the first gear 7; the first gear 7 is connected to the threaded screw 3; the upper end of the threaded screw 3 passes through the first gear 7 and is connected to the lifting rod 5.

[0046] During actual operation, after starting the driving device 2, the output end of the first motor 8 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the second gear 10 to rotate. At the same time, the first gear 7 also rotates with the rotation of the second gear 10, and the first gear 7 drives the threaded screw 3 to rotate. The rotation of the threaded screw 3 drives the lifting rod 5 to rotate and move upward or downward.

[0047] In some embodiments, Figure 1 , 2 As shown, the cover plate 6 and the support plate 1 are optimized. In this embodiment, a clearance component 12 is installed on the cover plate 6 and the support plate 1; a clamping component 13 is installed at both ends of the bottom end of the support plate 1; a pull wire component 14 is connected to the opening edge of the clearance component 12 on the bottom end of the cover plate 6; and a detection component 15 is installed at the bottom end of the support plate 1.

[0048] In fact, the function of the give way component 12 is to cooperate with the wire pulling component 14 to realize the auxiliary work of wire laying after the installation of the sealing device, and to provide an entrance for pouring concrete when pouring concrete to seal the hole on the other hand; the function of the clamping component 13 is to fix the sealing device when installing the sealing device to prevent the sealing device from being displaced due to external force, thereby causing failure to seal the hole; the function of the wire pulling component 14 is to assist in the wire laying work, which is convenient for construction personnel to carry out the wire laying work from bottom to top; the detection component 15 is used to detect the completion of pouring concrete when pouring concrete to seal the hole. When the concrete pouring is completed, the detection component 15 will be pressure-sensitive to remind the construction personnel to stop pouring concrete.

[0049] In some embodiments, Figure 3 As shown, the give-way component 12 is optimized. In this embodiment, the give-way component 12 includes a give-way opening 121, a first groove 122, a first electric telescopic rod 123 and a baffle 124. The give-way opening 121 is opened through the cover plate 6 and the support plate 1, and the opening positions of the two correspond to each other in the vertical direction; the first groove 122 is opened on the side wall of the give-way opening 121; the fixed end of the first electric telescopic rod 123 is connected to the side wall of the first groove 122, and the telescopic end is connected to the baffle 124; the side wall of the baffle 124 is in contact with the inner wall of the give-way opening 121, and can be accommodated in the first groove 122 through the first electric telescopic rod 123.

[0050] In the default state, the first electric telescopic rod 123 is in an extended state, and the baffle 124 is located in the make way opening 121 and blocks the make way opening 121; when it is necessary to cooperate with the wire pulling assembly 14 to assist in the wire releasing work, the first electric telescopic rod 123 will be transformed into a retracted state, and at the same time drive the baffle 124 to move toward the first groove 122, and finally accommodate the baffle 124 in the first groove 122.

[0051] In some embodiments, Figure 6 As shown, the clamping assembly 13 is optimized. In this embodiment, the clamping assembly 13 includes a second groove 131, a second electric telescopic rod 132, a clamping plate 133, a round rod 134 and a blocking plate 135. The second groove 131 is opened at both ends of the bottom of the support plate 1; the fixed end of the second electric telescopic rod 132 is connected to the upper wall of the second groove 131, and the telescopic end is connected to the clamping plate 133; the round rod 134 is rotatably connected to the side wall of the second groove 131 through a first torsion spring, and its rod wall is connected to the blocking plate 135.

[0052] In the default state, the second electric telescopic rod 132 is in a retracted state, and the clamping plate 133, the round rod 134 and the blocking plate 135 are all accommodated in the second groove 131; when installing the blocking device, after the support plate 1, the lifting rod 5 and the cover plate 6 are in place, the second electric telescopic rod 132 is changed to an extended state and drives the clamping plate 133 to move downward. When the clamping plate 133 moves downward, it provides a downward torque for the round rod 134 and the blocking plate 135, prompting the round rod 134 to rotate downward around the first torsion spring. When the clamping plate 133 is completely moved out of the second groove 131 and contacts the inner wall of the building floor opening, the second electric telescopic rod 132 stops extending and remains in the extended state. When the second electric telescopic rods 132 at both ends of the bottom of the cover plate 6 are all changed to the extended state, the entire blocking device can be fixed relative to the building floor opening to avoid movement due to external force, resulting in blocking dislocation and exposing the building floor opening to the outside.

[0053] In some embodiments, Figure 7 , 8As shown, the wire pulling assembly 14 is optimized. In this embodiment, the wire pulling assembly 14 includes a shell 141, a connecting plate 142, a second torsion spring 143, a winding rod 144, an L-shaped plate 1410, a mounting plate 1411, a stopper 1413 and a wire pulling wire 1414; the shell 141 is fixedly connected to the bottom end of the cover plate 6, and a strip opening 1412 is provided at the lower end thereof; the connecting plate 142 is vertically connected to the inner wall of the shell 141; one end of the winding rod 144 passes through the connecting plate 142 and can be It rotates around its own axis, and the other end is connected to the inner wall of the shell 141 through the second torsion spring 143; the two L-shaped plates 1410 are symmetrically and invertedly fixed to the support plate 1 below the shell 141; the stopper 1413 is connected to the side walls of the two L-shaped plates 1410 through the third torsion spring; one end of the pull wire 1414 is fixed on the winding rod 144, and the other end passes through the strip opening 1412 and is connected to the mounting plate 1411; the mounting plate 1411 is located below the plate wing of the L-shaped plate 1410.

[0054] When construction workers need to carry out line laying work, they move the wire of the lower layer from the clearance opening 121 to the current working layer, and wrap one end of the wire around the mounting plate 1411, then rotate the mounting plate 1411 90 degrees with the pull wire 1414 as the axis, so that the mounting plate 1411 extends out from the gap between the two L-shaped plates 1410, and at the same time rotate the winding rod 144 to make the pull wire 1414 continuously wrapped around the outer wall of the winding rod 144, and drive the mounting plate 1411 to move upward until the wire is moved under the cover plate 6. At this time, the staff on the upper layer removes the wire from the mounting plate 1411 through the clearance opening 121, pulls the wire to the upper layer, and then uses the upper layer's blocking device to continue transmitting the wire until all line laying work is completed.

[0055] In some embodiments, Figure 7 As shown, the wire pulling assembly 14 has been further optimized. In this embodiment, the wire pulling assembly 14 also includes a power mechanism: a second motor 146, a transmission rod 147, a third electric telescopic rod 148, a first magnet 145 and a second magnet 149. The second motor 146 is connected to the outer wall of the outer shell 141 at one end away from the winding rod 144; one end of the transmission rod 147 passes through the outer shell 141 and is connected to the output end of the second motor 146, and the other end is connected to the third electric telescopic rod 148; the fixed end of the electric telescopic rod 148 is connected to the transmission rod 147, and the telescopic end is connected to the second magnet 149; the first magnet 145 is connected to one end of the winding rod 144 that passes through the connecting plate 142.

[0056] When performing auxiliary work of line-releasing, the power mechanism can provide power support for rotating the winding rod 144. Specifically: by default, the third electric telescopic rod 148 is in a retracted state. When line-releasing is required, the third electric telescopic rod 148 is controlled to be transformed into an extended state, driving the second magnet 149 to move in the direction of the first magnet 145, so that the second magnet 149 contacts the first magnet 145. At this time, the first magnet 145 and the second magnet 149 are attracted to each other through magnetic force, and then the second motor 146 is started, so that the output end of the second motor 146 drives the transmission rod 147 to rotate, and the transmission rod 147 drives the third electric telescopic rod 148 to rotate, and then drives the second magnet 149 and the first magnet 145 to rotate, and finally achieves the purpose of driving the winding rod 144 to rotate.

[0057] In some embodiments, Figure 5 As shown, the detection component 15 is optimized. In this embodiment, the detection component 15 includes a third groove 151, a pressure sensor 152, a support spring 153 and a floating plate 154. The third groove 151 is opened at the bottom end of the support plate 1; the pressure sensor 152 is connected to the upper wall of the third groove 151; one end of the support spring 153 is connected to the pressure sensor 152, and the other end is connected to the floating plate 154.

[0058] When it is necessary to pour concrete to seal the opening of the building floor, pour the concrete into the opening of the building floor from the clearance opening 121, and use the lower cover plate 6 as a template to support the concrete. As the concrete is poured, when the concrete is poured to a certain height, it will push the floating plate 154 to overcome the elastic force of the support spring 153 and move toward the inside of the third groove 151. At this time, the pressure sensor 152 detects pressure, indicating that the concrete pouring is completed. At this time, stop pouring the concrete, wait for the concrete to solidify, and then remove the sealing device.

[0059] In some embodiments, Figure 2 As shown, the cover plate 6 is optimized. In this embodiment, a smoke detector 16 and an alarm 17 are connected to the bottom end of the cover plate 6 , and the alarm 17 is electrically connected to the smoke detector 16 .

[0060] In actual operation, when a fire occurs on the floor where the blocking device is located and smoke is generated, the smoke detector 16 can promptly detect the smoke in the air and transmit the fire signal to the alarm 17. The alarm 17 will simultaneously sound an alarm to inform the construction workers of the fire at the construction site, so that the construction workers can escape from the construction site in time when a fire occurs.

[0061] In some embodiments, Figure 1 As shown, the sleeve 4 is optimized, and in this embodiment, a warning light strip 18 is connected to the outer wall of the sleeve 4.

[0062] During actual work, the warning light strip 18 connected to the outer wall of the sleeve 4 can always remind the construction workers that there is a building floor opening nearby, so as to prevent the construction workers from stepping on empty space and falling from the building floor opening and causing accidents.

[0063] A construction method of a building floor opening blocking device, applicable to any of the above-mentioned building floor opening blocking devices, specifically comprising:

[0064] Place support plate 1: Place support plate 1 above the floor opening to cover the floor opening;

[0065] Start the driving device 2: start the first motor 8, so that the output end of the first motor 8 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the second gear 10 to rotate. At the same time, the first gear 7 also rotates with the rotation of the second gear 10, and the first gear 7 drives the threaded screw 3 to rotate. The rotation of the threaded screw 3 drives the lifting rod 5 to rotate and move upward, further driving the cover plate 6 to move upward. When the cover plate 6 contacts the upper building floor, the driving device 2 is closed;

[0066] Start the clamping assembly 13: Start the second electric telescopic rod 132, drive the clamping plate 133 to move downward, so that the round rod 134 overcomes the elastic force of the first torsion spring and drives the blocking plate 135 to rotate, and further drives the clamping plate 133 to move downward and extend from the second groove 131, so that the side wall of the clamping plate 133 conflicts with the inner wall of the floor opening, so that the support plate 1 does not move sideways, the support plate 1 is fixed, and the floor opening is blocked;

[0067] Disassembling the blocking device: control the second electric telescopic rod 132 to retract, so that the clamping plate 133 returns to the initial position, and at the same time control the driving device 2 to make the lifting rod 5 rotate in the opposite direction and descend, driving the cover plate 6 to move downward and away from the upper floor, and finally take away the entire device to realize the disassembly of the blocking device.

[0068] When it is necessary to release the wire, the first electric telescopic rod 123 is controlled to retract, driving the baffle 124 to move into the first groove 122, so that the baffle 124 does not block the clearance opening 121, and the wire of the lower layer is moved from the clearance opening 121 to the current working layer, and one end of the wire is wound around the mounting plate 1411, and then the mounting plate 1411 is rotated 90 degrees with the pulling wire 1414 as the axis, so that the mounting plate 1411 extends out from the gap between the two L-shaped plates 1410, and at the same time, the third electric telescopic rod 148 is controlled to extend, driving the second magnet 149 to move in the direction of the first magnet 145, so that the second magnet 149 contacts the first magnet 145, and the first magnet 145 contacts the second magnet 145. The iron 149 is attracted by magnetic force, and then the second motor 146 is started, so that the output end of the second motor 146 drives the transmission rod 147 to rotate, and the transmission rod 147 drives the third electric telescopic rod 148 to rotate, and then drives the second magnet 149, the first magnet 145 and the winding rod 144 to rotate. When the winding rod 144 is wound, the pull wire 1414 is continuously wound around the outer wall of the winding rod 144, and drives the mounting plate 1411 to move upward until the wire is moved to the bottom of the cover plate 6. At this time, the staff on the upper level removes the wire from the mounting plate 1411 through the yield opening 121, pulls the wire to the upper level, and then uses the upper level blocking device to continue to transmit the wire until all the wire laying work is completed.

[0069] When it is necessary to cast concrete to seal the opening of the building floor, first control the second electric telescopic rod 132 to contract, drive the clamping plate 133, the round rod 134 and the sealing plate 135 to be all accommodated in the second groove 131; then control the first electric telescopic rod 123 to contract, drive the baffle 124 to move into the first groove 122, so that the baffle 124 does not block the clearance opening 121; then pour the concrete from the clearance opening 121 into the opening of the building floor, and use the lower cover plate 6 as a template to support the concrete. As the concrete is poured, when the concrete is poured to a certain height, it will push the floating plate 154 to overcome the elastic force of the support spring 153 and move toward the inside of the third groove 151. At this time, the pressure sensor 152 detects pressure, indicating that the concrete pouring is completed. At this time, stop pouring the concrete, and wait for the concrete to solidify before disassembling the sealing device.
