Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to an edge safety protection device for roof construction. Background Technology

[0002] Edge protection refers to the protection of the perimeter of balconies without railings or the perimeter of roofs without external scaffolding to prevent falls and enhance safety. Existing roof structures vary, and for sloping roofs, external scaffolding is often erected. This method uses more materials, is more expensive, and involves a large amount of manual labor for assembly and disassembly, resulting in a longer construction period. Summary of the Invention

[0003] To reduce the construction period of roofing, this application provides an edge safety protection device for roofing construction.

[0004] This application provides a safety protection device for edges during roof construction, which adopts the following technical solution:

[0005] An edge safety protection device for roof construction includes multiple columns and a connecting rod installed between two columns. A cast-in-place area is formed at the bottom of the roof's sloping surface. Two U-shaped reinforcing bars are pre-embedded in the cast-in-place area and are arranged parallel to each other. A gap exists between the U-shaped reinforcing bars and the cast-in-place area, forming an installation space. Each column includes a pole, a first plate, and a second plate. The first and second plates are connected by a telescopic component. The pole is connected to the first plate, and the connecting rod is connected to the pole.

[0006] The length of the first plate is greater than the distance between the two U-shaped ribs, and a clamping component is provided between the first plate and the second plate; when the first plate and the second plate enter the installation space, the clamping component is used to clamp the first plate and the second plate against the opposite side walls of the installation space.

[0007] By adopting the above technical solution, when protecting the edge of the roof slope, the first and second plates are placed between two U-shaped ribs. Then, by rotating the uprights, the first and second plates are respectively placed into the installation space formed by the two U-shaped ribs and the surface of the cast-in-place area. At this time, using the clamping component, the first and second plates move to the side away from each other and clamp against the opposite side walls of the installation space. This completes the installation of the column and the roof, reduces the possibility of the first and second plates detaching from the installation space, and improves the stability of the column and roof installation.

[0008] Next, the connecting rods are installed to the columns, which can protect the workers on the roof. The installation method of the columns and the roof is relatively simple, which makes it easy to disassemble after the roof construction is completed, thus reducing the construction cycle. After the connection between the columns and the U-shaped bars is removed, the U-shaped bars can be hidden by pouring concrete in the cast-in-place area, which improves the aesthetics of the roof.

[0009] Optionally, the clamping assembly includes a rotating component and a base, the base being mounted on the side of the second plate near the first plate; the rotating component is rotatably mounted on the base, and the base divides the rotating component into a lifting portion and a pressing portion; the first plate is threaded with a bolt, the head of the bolt being rotatably connected to the pressing portion, and the lifting portion being used to abut against the bottom of the first plate.

[0010] By adopting the above technical solution, the bolt is tightened and rotated to the side of the second plate, thereby causing the pressing part to move toward the side of the second plate; and since the rotating part is rotated and installed on the base, the lifting part moves toward the first plate, so that the first plate and the second plate move toward the side away from each other, which can make the first plate and the second plate press against the opposite side walls of the installation space and reduce the possibility of separation.

[0011] Optionally, two sets of clamping components are provided, and the two sets of clamping components are respectively arranged at intervals along the length direction of the second plate. The pressing parts of the two rotating parts are connected, and the bolt is rotatably installed at the connection of the two pressing parts.

[0012] By adopting the above technical solution and setting two sets of clamping components, when the bolt is rotated toward one side of the second plate, the two lifting parts move toward one side of the first plate at the same time and lift it, so that both sides of the first plate in the length direction are simultaneously clamped to the opposite sides of the two U-shaped ribs, further improving the stability of the column installation on the roof.

[0013] Optionally, a support rod is provided in the middle of the roof, and a roller is rotatably mounted on the support rod. A steel wire rope is wound on the surface of the roller. The two ends of the steel wire rope are respectively connected to the uprights located on opposite sides of the roof.

[0014] By adopting the above technical solution and installing steel wire ropes, on the one hand, workers can hook their safety belts onto the steel wire ropes when working on the roof, and can also hold onto the steel wire ropes while walking, thus improving the safety of roof construction operations; on the other hand, if a worker accidentally falls and rolls onto the protective device, the column in contact with the worker will be subjected to pressure towards the side away from the supporting column, and the steel wire rope connected to that column will be subjected to tension. Since the two ends of the steel wire rope are connected to the columns on opposite sides of the roof respectively, the column on the side not in contact with the worker will provide a reverse force on the steel wire rope, that is, disperse the pressure on the column from the worker, reduce the possibility of the column breaking due to excessive bending, and improve the protection of workers.

[0015] Optionally, the wire rope is wound around the surface of the roller, and a torsion spring is provided between the support rod and the roller, the torsion spring being used to keep the wire rope taut.

[0016] By adopting the above technical solution and setting a torsion spring, the wire rope can be kept taut. When one end of the wire rope is subjected to a force toward the side away from the roller, both the torsion spring and the column located on the other side of the roof can provide directional force to the wire rope, further reducing the possibility of the column breaking due to excessive bending and improving the protective effect of the protective device.

[0017] Optionally, the end of the wire rope is fixed with a lobster buckle, and the upright is provided with a hanging ear, with the lobster buckle hooked to the hanging ear.

[0018] By adopting the above technical solution and setting up lobster clips, the connection between the steel wire rope and the upright can be easily removed after the roof construction is completed, making it easy to reuse the steel wire rope.

[0019] Optionally, the connecting rod includes a horizontal bar and a diagonal bar, both ends of which are connected by a mounting rod, and the mounting rod is detachably connected to the upright.

[0020] By adopting the above technical solution, and by setting up horizontal bars and diagonal bars, the triangle formed by the horizontal bars, diagonal bars and columns further improves the stability of the protective device, thereby enhancing the effective protection of roof construction workers.

[0021] Optionally, the mounting rod is provided with a plug-in rod, the outer wall of which is covered with a rubber sleeve; the upright is fixed with a mounting cylinder for the plug-in rod to be inserted into.

[0022] By adopting the above technical solution, the connecting rod can be installed between the columns through the insertion and engagement of the plug-in rod and the mounting cylinder. This installation method is relatively convenient and improves the disassembly efficiency of workers. Furthermore, the addition of a rubber sleeve further enhances the stability of the plug-in rod when inserted into the mounting cylinder.

[0023] Optionally, the telescopic component includes a sleeve, a movable rod, and a first spring. The sleeve is fixed to the second plate, the movable rod is fixed to the first plate, and the movable rod is movably installed inside the sleeve. The first spring is installed between the movable rod and the sleeve, and the first spring is kept in a compressed state.

[0024] By adopting the above technical solution, and by setting a first spring, the elastic force of the first spring can cause the first plate and the second plate to be subjected to a force that brings them closer together; when the first plate and the second plate are not installed between the two U-shaped ribs, the free swaying between the first plate and the second plate can be reduced.

[0025] Optionally, a rubber pad is provided on the side of the first plate away from the second plate.

[0026] By adopting the above technical solution and setting rubber pads, when the first plate and the second plate are pressed against the opposite side walls of the installation space, the first plate abuts against the U-shaped rib and causes the rubber pad to deform under force, further reducing the possibility of the first plate rotating out of the installation space and improving the stability of the column installation on the roof.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up columns and U-shaped reinforcements embedded in the cast-in-place area, the pull-out resistance of the columns on the roof can be improved, reducing the possibility of the columns detaching from the roof. It can also improve the impact resistance of the protective device on the roof slope, reducing the possibility of the U-shaped reinforcements detaching when workers accidentally roll down. Moreover, the structure is simple and easy for workers to assemble on the roof.

[0029] 2. By setting up a clamping component, the pressing part and the lifting part can be moved toward the side away from each other by rotating the bolts, so that the first plate and the second plate can move toward the side away from each other and clamp against the opposite sides of the installation space, thereby improving the stability of the column after installation on the roof.

[0030] 3. By installing steel wire ropes, when a worker accidentally falls and rolls onto the protective device, the column in contact with the worker is subjected to pressure towards the side away from the support column. The steel wire ropes can provide a reverse force to the column, which can reduce the impact force on the column, reduce the possibility of the column breaking due to excessive bending, and improve the protection of the worker.

[0044] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail. Example

[0045] This application discloses an edge safety protection device for roof construction.

[0046] Reference Figure 1 A safety protection device for the edge of a roof 3 during construction includes multiple columns 1 and a connecting rod 2 installed between two columns 1. The roof 3 has two sloping surfaces, and a cast-in-place area 31 is provided at the bottom of each of the two sloping surfaces. The columns 1 are installed in the cast-in-place area 31.

[0047] Reference Figure 1 and Figure 2 Multiple U-shaped ribs 32 are cast in the cast-in-place area 31, and the U-shaped ribs 32 are arranged in pairs. Each U-shaped rib 32 includes a first rod 321, two inclined rods 322 and two second rods 323. One end of each of the two second rods 323 is connected to the two inclined rods 322 respectively. Both ends of the first rod 321 are connected to the ends of the inclined rods 322 away from the second rods 323 respectively. The two first rods 321 are pre-embedded in the cast-in-place area 31 of the roof 3. The U-shaped ribs 32 have gaps with the surface of the cast-in-place area 31 and form an installation space 33.

[0048] Reference Figure 3 The column 1 includes a first plate 12, a second plate 13, and a pole 11. The pole 11 is welded to one side of the first plate 12 and is connected to a connecting rod 2. A telescopic assembly 14 is installed on the side of the first plate 12 away from the pole 11 and is connected to the second plate 13. The telescopic assembly 14 is used to movably connect the first plate 12 and the second plate 13. The length of the first plate 12 is greater than the spacing between the two U-shaped ribs 32, and the width of the first plate 12 is the same as the length of the first pole 321. When the column 1 is installed in the cast-in-place area 31, the two ends of the first plate 12 and the second plate 13 are respectively inserted into the installation space 33 of the two U-shaped ribs 32.

[0049] Reference Figure 4 The telescopic assembly 14 includes a sleeve 141, a movable rod 142, and a first spring 143. The sleeve 141 is welded to the second plate 13, and the side of the sleeve 141 with an opening faces the first plate 12. The movable rod 142 is welded to the first plate 12 and is movably installed inside the sleeve 141. The two ends of the first spring 143 are fixed to the movable rod 142 and the sleeve 141, respectively. The spring of the first spring 143 is in a compressed state, that is, the elastic force of the first spring 143 forces the first plate 12 and the second plate 13 to move toward each other.

[0050] Reference Figure 3 and Figure 4 A clamping component 4 is provided between the first plate 12 and the second plate 13. The clamping component 4 can change the minimum distance between the first plate 12 and the second plate 13. That is, when the first plate 12 and the second plate 13 are installed in the installation space 33, the first plate 12 is clamped against the first rod 321, and the second plate 13 is clamped against the surface of the cast-in-place area 31.

[0051] Reference Figure 3 Two sets of clamping components 4 are provided, and the two sets of clamping components 4 are spaced apart along the length direction of the first plate 12. The clamping component 4 includes a rotating member 41 and two bases 42. The two bases 42 are fixed to the second plate 13 and spaced apart along the width direction of the second plate 13. The rotating member 41 is rotatably mounted between the two bases 42 via a rotating shaft 43. The rotating shaft 43 divides the rotating member 41 into a lifting part 45 and a pressing part 44. The pressing parts 44 of the two rotating members 41 are connected by a connecting plate 46, and the connecting plate 46 is hinged to the pressing parts 44 respectively.

[0052] The first plate 12 has a threaded hole 16, and a bolt 15 is installed in the threaded hole 16. The connecting plate 46 has a rotating groove 47, and the bolt 15 passes through the threaded hole 16 and is rotatably connected to the rotating groove 47. By changing the position of the bolt 15 between the threaded hole 16, the pressing part 44 can be moved closer to the side of the second plate 13, so that the lifting part 45 can be connected to the first plate 12 and the first plate 12 can be moved away from the side of the second plate 13, so that the first plate 12 and the second plate 13 respectively abut against the opposite side walls of the installation space 33.

[0053] A rubber pad 17 is provided on the side of the first plate 12 away from the second plate 13. When the first plate 12 and the second plate 13 are pressed against the opposite side walls of the installation space 33, the rubber pad 17 can abut against the U-shaped rib 32 and deform. This improves the stability of the column 1 installed in the cast-in-place area 31 and further reduces the possibility of rotation after the first plate 12 and the second plate 13 are pressed against the installation space 33.

[0054] Reference Figure 5 A mounting cylinder 18 is welded to the side wall of the upright 11. The connecting rod 2 includes a diagonal rod 22 and a horizontal rod 21. Both ends of the horizontal rod 21 and the diagonal rod 22 are connected by a mounting rod 23. The extension direction of the diagonal rod 22 intersects the extension direction of the horizontal rod 21. An insert rod 24 is integrally formed on the side wall of the mounting rod 23. The insert rod 24 is used to insert into the mounting cylinder 18. The outer wall of the insert rod 24 is covered with a rubber sleeve. When the diagonal rod 22 and the horizontal rod 21 are installed between the two uprights 11, the insert rod 24 is inserted into the mounting cylinder 18 with an interference fit. This reduces the free movement of the insert rod 24 within the mounting cylinder 18 and improves the stability of the connecting rod 2 installed on the upright 11.

[0055] The horizontal bar 21, the diagonal bar 22, and the vertical bar 11 form a triangle, which increases the stability of the protective device and thus improves its protective effect. After the roof 3 is completed, the insert rod can be removed from the installation cylinder 18, thereby completing the disassembly of the connecting rod 2. This facilitates repeated use and reuse of the connecting rod 2, improves the ease of assembly and disassembly between the connecting rod 2 and the vertical bar 11, and further reduces the construction cycle.

[0056] The implementation principle of Embodiment 1 of this application is as follows:

[0057] When performing edge protection on the slope of the roof 3, the first plate 12 and the second plate 13 are placed between the two U-shaped ribs 32. Then, by rotating the upright 11, the first plate 12 and the second plate 13 are rotated and their ends are respectively inserted into the installation space 33 of the two U-shaped ribs 32. At this time, the bolt 15 is rotated toward the side of the second plate 13, so that the pressing part 44 moves closer to the side of the second plate 13. This allows the lifting part 45 to tilt upward and move closer to the side of the first plate 12, thereby moving the first plate 12 and the second plate 13 away from each other and pressing them against the opposite sides of the installation space 33 to complete the fixing of the column 1 to the roof 3. Then, the plug rod 24 is inserted into the installation cylinder 18, thus completing the installation between the connecting rod 2 and the column 1.

[0058] Embedding the U-shaped reinforcing bar 32 within the cast-in-place area 31 improves the pull-out resistance of the column 1 to the roof 3, reducing the likelihood of the column 1 detaching from the roof 3. It also enhances the impact resistance of the protective device on the slope of the roof 3, reducing the possibility of the U-shaped reinforcing bar 32 detaching if workers accidentally fall. Furthermore, the installation method between the column 1 and the roof 3, and between the column 1 and the connecting rod 2, is relatively convenient, facilitating disassembly and assembly by workers, improving construction efficiency, and reducing the construction period.

[0059] After the columns 1 and the roof 3 are removed, concrete is poured into the cast-in-place area 31 to cover the U-shaped reinforcement 32 in the cast-in-place area 31, thereby improving the aesthetics of the roof 3 after construction. Example

[0060] This application discloses an edge safety protection device for roof construction.

[0061] Reference Figure 7 and Figure 8The difference between Embodiment 2 and Embodiment 1 is that: a support rod 5 is installed in the middle of the roof 3, and the support rod 5 is located at the highest point of the roof 3; an installation column is pre-embedded in the roof 3, and the installation column has an installation groove 35 for the support rod 5 to be inserted. In this embodiment, the cross-section of the support column 34 is square, that is, the support rod 5 can be inserted into the installation groove 35 to reduce the occurrence of free rotation; the inner wall of the installation groove 35 has an insertion groove 36.

[0062] Reference Figure 9 The support rod 5 has a rotation space 52, and a rotating elliptical wheel 53 is rotatably installed in the rotation space 52. Multiple sharp teeth 531 are provided on both sides of the maximum diameter of the elliptical wheel 53. The mounting column has sliding grooves 521 on both sides, which are connected to the rotation space 52. A plug-in block 54 is slidably installed in the sliding groove 521 and is plugged into the plug-in groove 36. An anti-detachment block 542 is provided on the outer wall of the plug-in block 54. An anti-detachment groove 522 is provided on the inner wall of the sliding groove 521 for the anti-detachment block 542 to slide. A second spring 543 is provided between the anti-detachment block 542 and the inner wall of the anti-detachment groove 522. The elastic force of the second spring 543 forces the plug-in block 54 to move toward one side of the rotation space 52.

[0063] The plug block 54 has a toothed groove 541 on the side near the rotation space 52. When the elliptical wheel 53 rotates and the sharp teeth 531 engage with the toothed groove 541 of the plug block 54, the plug block 54 moves toward the side away from the rotation space 52 and is inserted into the plug groove 36, thereby completing the fixation of the support rod 5 and the support column 34.

[0064] Reference Figure 10 A turbine 56 is rotatably installed in the rotating space 52. The turbine 56 is fixed to the elliptical wheel 53 by a rotating rod 55. The support rod 5 has a through hole 523, which is connected to the rotating space 52. A worm 57 is inserted in the through hole 523. The extension direction of the worm 57 is perpendicular to the extension direction of the support rod 5. The worm 57 cooperates with the turbine 56. The outer wall of the worm 57 is provided with a threaded part 571. The inner wall of the through hole 523 is provided with a threaded groove. The threaded part 571 cooperates with the threaded groove.

[0065] Rotating the worm gear 57 causes the turbine 56 to rotate. Since the elliptical wheel 53 is connected to the turbine 56 via the rotating rod 55, the elliptical wheel 53 can also rotate. When the sharp teeth 531 of the elliptical wheel 53 engage with the tooth groove 541 of the insert block 54, it becomes more difficult for the operator to rotate the worm gear 57, indicating that the insert block 54 is inserted into the insert groove 36, completing the connection between the support rod 5 and the support column 34. When it is necessary to disassemble the support rod 5, the worm gear 57 is rotated again, requiring the sharp teeth 531 to engage with the tooth groove 541. At this time, the insert block 54 moves towards one side of the rotation space 52 under the spring force, thereby canceling the insertion engagement between the insert block 54 and the insert groove 36, allowing the support rod 5 to be disassembled.

[0066] Reference Figure 11 The support rod 5 is located at the highest point of the roof 3. A roller 51 is rotatably installed at the end of the support rod 5 away from the roof 3. A torsion spring is provided between the roller 51 and the support rod 5. A steel wire rope 6 is wound on the surface of the roller 51. The two ends of the steel wire rope 6 are respectively connected to the columns 1 on the slopes on both sides of the roof 3. The elastic force of the torsion spring can keep the steel wire rope 6 in a taut state.

[0067] Reference Figure 12 The end of the steel wire rope 6 is fixed with a lobster buckle 61, and the side of the upright 11 away from the cast-in-place area 31 is fixed with an ear plate. The ear plate has an installation hole 63, and the lobster buckle 61 is hooked into the installation hole 63 of the ear plate. By setting the lobster buckle 61, the steel wire rope 6 can be easily disassembled and reused after the roof 3 is constructed; and after the support rod 5 is disassembled, concrete is poured into the installation groove 35 in the support column 34 and its surface is plastered, thereby concealing the support column 34.

[0068] The implementation principle of Embodiment 2 of this application is as follows:

[0069] When workers are working on the slope of roof 3, they can hook their safety belts onto the wire rope 6 and hold onto the wire rope 6 while walking, thereby improving the safety of roof 3 construction work. If a worker accidentally falls and rolls onto the protective device, the column 1 in contact with the worker will be subjected to pressure on the side away from the support rod 5. At this time, the column 1 on the side not in contact with the worker will provide tension to the wire rope 6, that is, reduce the impact force on the column 1 from the worker, thereby reducing the possibility of the column 1 breaking due to excessive bending, and further improving the protection of the worker.

[0070] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
