Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a building scaffolding support structure adapted to the shape of the exterior wall. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is classified into external scaffolding and internal scaffolding according to its location; and into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding according to different materials. It is widely used in construction, bridges, factories and other fields.

[0003] Existing buildings often feature protruding structures such as waistlines on the facade to emphasize the building's overall appearance and enhance its visual appeal. However, when erecting scaffolding on such facades, these protruding structures obstruct the formwork erection process. Therefore, care must be taken to avoid corners where the scaffolding is positioned relative to the protruding structures, reducing the efficiency of the erection. Furthermore, corners formed by scaffolding at protruding structures can lead to insufficient structural strength at those locations, posing safety hazards. Therefore, further improvements are needed. Summary of the Invention

[0004] In order to improve the efficiency of scaffolding formwork erection and the structural strength of scaffolding formwork located at protruding structural parts of buildings, this application provides a building external scaffolding formwork structure that adapts to the shape of the exterior wall.

[0005] The technical solution provided in this application for a building scaffolding support structure adapted to the shape of exterior walls is as follows: An external scaffolding support structure adapted to the shape of an exterior wall includes a first vertical rod, a second vertical rod, and sleeves. Multiple first and second vertical rods are provided. Each first vertical rod is equipped with an abutment member, which is used to abut against the upper or lower surface of a protruding structure. The first vertical rod abuts against the protruding structure through the abutment member. The number of sleeves corresponds to the number of second vertical rods. All sleeves are pre-embedded in the protruding structure to form multiple through-channels, through which the second vertical rods pass. Connecting rods can be detachably installed between adjacent first vertical rods, between adjacent second vertical rods, and between adjacent first and second vertical rods. All first vertical rods and all second vertical rods are connected as a whole by the connecting rods.

[0006] By adopting the above technical solution, through the setting of sleeves and clamping parts, multiple sleeves are pre-embedded in the protruding structure during the construction of the building's protruding structure, forming multiple through-passage channels. During the erection of scaffolding formwork, multiple second vertical members are correspondingly inserted into the through-passage channels. Multiple first vertical members are respectively clamped to the upper or lower surface of the protruding structure by clamping parts, and then connected to each other by connecting rods to form an integral scaffolding formwork. The second vertical members are inserted into the through-passage channels, thus eliminating the need to create corners at the location of the scaffolding formwork on the protruding structure, improving the erection efficiency of the scaffolding formwork. The inner wall of the through-passage channels limits the second vertical members, reducing the possibility of the scaffolding formwork tipping over, greatly improving the structural strength of the scaffolding formwork at the location of the protruding structure of the building, and reducing safety hazards.

[0007] Optionally, the outer peripheral wall of the second vertical rod is slidably fitted with a lower limit sleeve and an upper limit sleeve, which are respectively used to be inserted at both ends of the through-channel. The outer diameter of the lower limit sleeve is adapted to the inner diameter of the sleeve, and the inner diameter of the lower limit sleeve is adapted to the outer diameter of the upper limit sleeve. The inner peripheral wall of the lower limit sleeve and the outer peripheral wall of the upper limit sleeve are threadedly connected. The lower limit sleeve is provided with a fastening member. When the lower limit sleeve and the upper limit sleeve approach each other, the fastening member abuts against the outer peripheral wall of the second vertical rod.

[0008] By adopting the above technical solution, after the second vertical rod is inserted into the through-channel through the setting of the lower limit sleeve and the upper limit sleeve, the lower limit sleeve is inserted into the through-channel from the lower end, and the upper limit sleeve is inserted into the through-channel from the upper end, so that the upper limit sleeve is inserted into the lower limit sleeve. Then, the lower limit sleeve is fixed by a tool and the upper limit sleeve is rotated so that the lower limit sleeve and the upper limit sleeve are close to each other. The fastening member of the lower limit sleeve can abut against the outer peripheral wall of the second vertical rod to further limit the second vertical rod, reduce the possibility of the second vertical rod swaying in the through-channel, and thus improve the structural stability of the scaffold formwork.

[0009] Optionally, the fastening member includes a plurality of elastic plates, which are arranged at axial intervals around the lower limiting sleeve. One end of each elastic plate is connected to the inner peripheral wall of the lower limiting sleeve. When the lower limiting sleeve and the upper limiting sleeve approach each other, the upper limiting sleeve forces the elastic plate to deform and press against the outer peripheral wall of the second vertical rod.

[0010] By adopting the above technical solution, and through the setting of the elastic sheet, when the lower limit sleeve and the upper limit sleeve approach each other, the end face of the upper limit sleeve can push the elastic sheet and force the elastic sheet to deform, so that the elastic sheet abuts against the outer peripheral wall of the second vertical rod. As the lower limit sleeve and the upper limit sleeve continue to approach each other, the elastic sheet can be firmly pressed against the outer peripheral wall of the second vertical rod, thereby improving the structural stability of the second vertical rod.

[0011] Optionally, the end face of the upper limit sleeve away from the lower limit sleeve is provided with a rotating ring, and the peripheral wall of the rotating ring is provided with a rotating rod for driving the rotating ring to rotate; a connecting piece is provided between the rotating rods of the upper limit sleeves in two adjacent passage channels, and the rotating rods of the upper limit sleeves in two adjacent passage channels are detachably connected by the connecting piece.

[0012] By adopting the above technical solution, and through the setting of the rotating rod and the connecting piece, after the upper limit sleeve is inserted into the through-channel and then into the lower limit sleeve, the rotating rod drives the rotating ring to rotate, thereby driving the lower limit sleeve and the upper limit sleeve to move closer to each other. After the lower limit sleeve and the upper limit sleeve move closer to each other to limit the second vertical rod, the rotating rods of the upper limit sleeves in the two adjacent through-channels are connected to each other through the connecting piece. The two rotating rods limit each other to fix the relative position of the rotating rods, reduce the possibility of the rotating rods rotating freely and causing the lower limit sleeve and the upper limit sleeve to move away from each other, thereby improving the limiting effect of the second vertical rod.

[0013] Optionally, a docking hole is provided on the peripheral wall of the end of the rotating rod away from the rotating ring. The docking component includes a docking rod with two docking parts. The two docking parts are respectively used to be inserted into the docking holes of the rotating rods of two adjacent upper limit sleeves. The rotating rods of the two adjacent upper limit sleeves are connected to each other through the docking rod.

[0014] By adopting the above technical solution, after the lower limit sleeve and the upper limit sleeve limit the second vertical rod by setting the connecting rod, the two connecting parts of the connecting rod are respectively inserted into the connecting holes of the two adjacent rotating rods, so that the two rotating rods are connected together, making the rotating ring unable to rotate freely, thereby improving the limiting effect of the second vertical rod.

[0015] Optionally, the docking component includes a docking sleeve and a return spring. The docking sleeve is slidably fitted onto the outer peripheral wall of the end of the rotating rod away from the rotating ring. The return spring is installed between the docking sleeve and the rotating rod. In its normal state, the return spring causes the docking sleeve to partially move out of the end face of the rotating rod away from the rotating ring, so that the docking sleeve is fitted onto the outer peripheral wall of the rotating rod of the adjacent upper limit sleeve.

[0016] By adopting the above technical solution, through the setting of the docking sleeve and the return spring, the docking sleeve is pulled and forced to move towards the side closer to the rotating ring to squeeze the return spring, and then the rotating rod is driven to rotate. When the lower limit sleeve and the upper limit sleeve limit the second vertical rod and the end faces of the two rotating rods rotate to the opposite side, the docking sleeve is released. Under the action of the return spring, the docking sleeve is sleeved on the outer peripheral wall of the adjacent rotating rod, thereby connecting the two adjacent rotating rods into a whole, so that the rotating ring cannot rotate freely, and improving the limiting effect of the second vertical rod.

[0017] Optionally, the first vertical pole is provided with a triangular support frame, and a connector is provided between the triangular support frame and the first vertical pole. The triangular support frame is detachably installed on the first vertical pole through the connector. A protective frame is connected to the side of the triangular support frame away from the first vertical pole, and a safety protection zone for personnel to work on the edge is formed between the protective frame and the building facade.

[0018] By adopting the above technical solution, and through the setting of the triangular support frame and the protective frame, the triangular support frame provides an installation carrier for the protective frame, so that a safety protection zone for personnel to work on the edge is formed between the protective frame and the building facade, thereby improving the safety of the overall structural construction.

[0019] Optionally, a reinforcing rod is provided between the protective frame and the rotating ring. One end of the reinforcing rod rotates on the protective frame, and the other end is rotatably connected to the rotating ring. When the lower limit sleeve and the upper limit sleeve approach each other, the reinforcing rod exerts a tensile force on the protective frame.

[0020] By adopting the above technical solution and setting the reinforcing rod, on the one hand, the protective frame is connected to the first vertical rod through the triangular support frame and to the second vertical rod through the reinforcing rod, which indirectly improves the connection stability between the first vertical rod and the second vertical rod; on the other hand, when the lower limit sleeve and the upper limit sleeve approach each other, the reinforcing rod exerts a tensile force on the protective frame to improve the installation stability of the protective frame, thereby improving the safety of the overall structural construction.

[0021] Optionally, a reinforcing plate is provided on the side of the protective frame away from the rotating ring, and the end of the reinforcing rod away from the rotating ring is rotatably mounted on the reinforcing plate. The reinforcing rod is rotatably connected to the protective frame through the reinforcing plate. A clamping member is provided between the reinforcing plate and the protective frame, and the reinforcing plate and the protective frame are detachably connected through the clamping member.

[0022] By adopting the above technical solution, and by setting up reinforcing plates and clamping components, the reinforcing rod can be detachably installed on the protective frame.

[0023] Optionally, the protective frame includes multiple protective rods, and the clamping member includes a clamping ring for clamping the protective rods. The clamping ring is elastically set and fixed to the side wall of the reinforcing plate near the protective rod. The outer peripheral wall of the clamping ring has an inlet and outlet for the protective rod to enter and exit. The side wall of the clamping ring located at the inlet and outlet has a guide block for driving the clamping ring to deform. The guide block has a guide surface.

[0024] By adopting the above technical solution, through the setting of the clamping ring, when the reinforcing rod is connected to the protective frame, the inlet and outlet of the clamping ring of the reinforcing plate are aligned with the protective rod of the protective frame and pushed. When the guide block of the clamping ring abuts against the protective rod, the protective rod forces the clamping ring to deform through the guide surface of the guide block, thereby opening the inlet and outlet of the clamping ring, so that the protective rod can be fastened in the clamping ring, improving the connection convenience between the reinforcing plate and the protective frame, and thus improving the connection convenience between the reinforcing rod and the protective frame.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By using sleeves and clamping elements, multiple sleeves are pre-embedded in the protruding structure during its construction, forming multiple through-passage channels. During scaffolding formwork erection, multiple second vertical members are inserted one-to-one into these through-passage channels. Multiple first vertical members are clamped to the upper or lower surface of the protruding structure via clamping elements, and then connected to each other via connecting rods to form an integrated scaffolding formwork. The second vertical members are inserted into the through-passage channels, eliminating the need to create corners at the protruding structure location, thus improving the efficiency of scaffolding formwork erection. The inner wall of the through-passage channels limits the second vertical members, reducing the possibility of scaffolding formwork collapse, significantly improving the structural strength of the scaffolding formwork at the protruding structure location, and reducing safety hazards. 2. By setting up the rotating rod and the connecting piece, after the upper limit sleeve is inserted into the through-channel and then into the lower limit sleeve, the rotating rod drives the rotating ring to rotate, thereby driving the lower limit sleeve and the upper limit sleeve to move closer to each other. After the lower limit sleeve and the upper limit sleeve move closer to each other to limit the second vertical rod, the rotating rods of the upper limit sleeves in the two adjacent through-channels are connected to each other through the connecting piece. The two rotating rods limit each other to fix the relative position of the rotating rods, reduce the possibility of the rotating rods rotating freely and causing the lower limit sleeve and the upper limit sleeve to move away from each other, thereby improving the limiting effect of the second vertical rod. 3. By setting up the reinforcing rod, on the one hand, the protective frame is connected to the first vertical rod through the triangular support frame and to the second vertical rod through the reinforcing rod, which indirectly improves the connection stability between the first vertical rod and the second vertical rod; on the other hand, when the lower limit sleeve and the upper limit sleeve are close to each other, the reinforcing rod exerts a tensile force on the protective frame to improve the installation stability of the protective frame, thereby improving the safety of the overall structural construction.

[0028] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0029] Example 1: This application discloses a building scaffolding support structure adapted to the shape of the exterior wall, which is suitable for the scaffolding support and erection of buildings with protruding structures.

[0030] Reference Figure 1 A building scaffolding support structure adapted to the shape of the exterior wall includes a first vertical rod 1, a second vertical rod 2, and a sleeve 3. In this embodiment, multiple first vertical rods 1, multiple second vertical rods 2, and multiple sleeves 3 are provided. It should be noted that the first vertical rod 1 and the second vertical rod 2 are both formed by splicing multiple unit vertical rods. Multiple unit vertical rods are spliced ​​together by scaffolding clamps (scaffolding clamps are a common method in this field, and their structure will not be described in detail here, nor is it shown in the figure), and are combined to form a first vertical rod 1 or a second vertical rod 2 of a certain length.

[0031] Reference Figure 1The first vertical pole 1 and the second vertical pole 2 are both vertically arranged. Connecting rods 5 can be detachably installed between two adjacent first vertical poles 1, between two adjacent second vertical poles 2, and between adjacent first vertical poles 1 and second vertical poles 2. All first vertical poles 1 and all second vertical poles 2 are connected into a whole by connecting rods 5 to form the external scaffolding formwork of the building. In this embodiment, the connection between the connecting rod 5 and the first vertical pole 1 and the connection between the connecting rod 5 and the second vertical pole 2 are both detachably installed in the form of scaffolding clamps.

[0032] Reference Figure 1 , Figure 2 Each first vertical rod 1 has abutment members 4 installed at both ends. The abutment members 4 are used to press against the upper surface or lower surface of the protruding structure 9 of the building. The first vertical rod 1 is pressed against the protruding structure 9 by the abutment members 4. In this embodiment, the abutment member 4 includes an abutment sleeve 41 and an abutment screw 42. One end of the abutment sleeve 41 is detachably installed on the end face of the first vertical rod 1 by means of a scaffolding clamp. One end of the abutment screw 42 is slidably inserted into the abutment sleeve 41, and the other end... A stop block 43 is fixedly installed, which is used to abut against the upper surface or the lower surface of the protruding structure 9; an adjusting head 44 is rotatably installed on the outer peripheral wall of the end of the stop sleeve 41 away from the first vertical rod 1, and a stop screw 42 passes through the adjusting head 44 and is threadedly connected to the adjusting head 44; driving the adjusting head 44 to rotate around the axial direction of the stop sleeve 41 can drive the stop screw 42 to extend or extend into the stop sleeve 41, so that the stop block 43 can abut against the protruding structure 9.

[0033] Reference Figure 1 , Figure 3 In this embodiment, the number of second vertical rods 2 corresponds to the number of sleeves 3; the sleeves 3 are set as circular tubular structures with open ends, and the sleeves 3 are PVC sleeves 3. All sleeves 3 are used to be pre-embedded in the protruding structure 9 and form multiple through channels 31. All through channels 31 are set in correspondence with all second vertical rods 2, and each second vertical rod 2 is inserted into the corresponding through channel 31. With this design, the through channels 31 limit the second vertical rods 2 and improve the structural stability of the scaffold formwork.

[0034] Reference Figure 1 , Figure 3The outer periphery of the second vertical rod 2 is fitted with a lower limiting sleeve 21 and an upper limiting sleeve 22, respectively. The lower limiting sleeve 21 and the upper limiting sleeve 22 are respectively used to insert into the two ends of the through-channel 31. That is, the lower limiting sleeve 21 is inserted into the through-channel 31 through the lower opening, and the upper limiting sleeve 22 is inserted into the through-channel 31 through the upper opening. The outer diameter of the lower limiting sleeve 21 is adapted to the inner diameter of the sleeve 3, and the inner diameter of the lower limiting sleeve 21 is adapted to the outer diameter of the upper limiting sleeve 22. The lower limit sleeve 21 and the upper limit sleeve 22 are threaded together so that the lower limit sleeve 21 and the upper limit sleeve 22 can move closer to each other or further away from each other. In this embodiment, a rotating head 26 is fixedly installed on the end face of the lower limit sleeve 21 away from the upper limit sleeve 22 and the end face of the upper limit sleeve 22 away from the lower limit sleeve 21. The cross-sectional shape of the rotating head 26 is polygonal so as to connect with tools such as wrenches, and drive the lower limit sleeve 21 or the upper limit sleeve 22 to rotate so that the lower limit sleeve 21 and the upper limit sleeve 22 can move closer to each other or further away from each other.

[0035] Reference Figure 3 A fastening element is installed inside the lower limit sleeve 21. When the lower limit sleeve 21 and the upper limit sleeve 22 approach each other, the fastening element abuts against the outer peripheral wall of the second vertical rod 2. The fastening element includes multiple elastic pieces 23. The elastic pieces 23 are elastically arranged. All elastic pieces 23 are arranged at intervals around the axial direction of the lower limit sleeve 21. One end of each elastic piece 23 is fixedly connected to the inner peripheral wall of the lower limit sleeve 21. When the lower limit sleeve 21 and the upper limit sleeve 22 approach each other, the upper limit sleeve 22 abuts against the side wall of the elastic piece 23 and forces the elastic piece 23 to deform so that all elastic pieces 23 abut against the outer peripheral wall of the second vertical rod 2.

[0036] The implementation principle of Embodiment 1 of this application is as follows: On the one hand, the sleeve 3 is pre-embedded in the protruding structure 9 of the building, so that when the scaffolding formwork is erected on the exterior of the building, the second vertical rod 2 can pass through the passage channel 31 of the sleeve 3 without having to avoid the protruding structure 9 of the building, which improves the erection efficiency of the scaffolding formwork and allows the scaffolding formwork to adapt to the shape of the building exterior wall; on the other hand, the second vertical rod 2 passes through the passage channel 31, and the passage channel 31 limits the second vertical rod 2, reducing the possibility of the scaffolding formwork tilting, improving the structural stability of the scaffolding formwork, and ensuring construction safety.

[0037] Example 2: This application discloses a building scaffolding support structure adapted to the shape of the exterior wall.

[0038] Reference Figure 4 The difference between the building scaffolding support structure adapted to the exterior wall shape disclosed in this application and Embodiment 1 is that: In this embodiment, each upper limit sleeve 22 in the through-channel 31 is provided with a rotating ring 24. The rotating ring 24 is used to drive the upper limit sleeve 22 to rotate. The rotating ring 24 is fixedly installed on the end face of the upper limit sleeve 22 away from the lower limit sleeve 21. A rotating rod 25 is fixedly installed on the rotating ring 24. One end of the rotating rod 25 is fixedly connected to the outer peripheral wall of the rotating ring 24. For ease of description, the end of the rotating rod 25 away from the rotating ring 24 is defined as the free end of the rotating rod 25.

[0039] Reference Figure 4 When the free ends of the rotating rods 25 of the upper limit sleeves 22 in the two adjacent passages 31 rotate to a relative state, the upper limit sleeves 22 and the lower limit sleeves 21 approach each other so that the elastic piece 23 abuts against the outer peripheral wall of the second vertical rod 2; a connecting piece 6 is installed between the two adjacent rotating rods 25, and the rotating rods 25 of the upper limit sleeves 22 in the two adjacent passages 31 are detachably connected by the connecting piece 6.

[0040] Reference Figure 4 The outer peripheral wall of the free end of the rotating rod 25 is provided with a docking hole 251 that passes through the rotating rod 25. In this embodiment, the docking part 6 is set as a docking rod 61. The docking rod 61 is long and narrow. The two ends of the docking rod 61 are bent to form a U-shaped structure and form two docking parts 611. The two docking parts 611 are respectively used to be inserted into the docking holes 251 of the rotating rods 25 of the two adjacent upper limit sleeves 22. The two adjacent rotating rods 25 are connected to each other through the docking rod 61.

[0041] The implementation principle of Embodiment 2 of this application is as follows: the rotating ring 24 is driven to rotate by the rotating rod 25, which forces the lower limiting sleeve 21 and the upper limiting sleeve 22 to move closer to each other, so that the elastic piece 23 abuts against the outer peripheral wall of the second vertical rod 2, thereby further limiting the position of the second vertical rod 2. Then, the two docking parts 611 of the docking rod 61 are respectively inserted into the docking holes 251 of the two adjacent rotating rods 25, so that the two adjacent rotating rods 25 are connected as a whole, thereby limiting the two adjacent upper limiting sleeves 22, reducing the possibility that the upper limiting sleeve 22 will rotate freely and cause the lower limiting sleeve 21 and the upper limiting sleeve 22 to move away from each other, thereby keeping the elastic piece 23 abutting against the second vertical rod 2 and improving the limiting effect on the second vertical rod 2.

[0042] Example 3: This application discloses a building scaffolding support structure adapted to the shape of the exterior wall.

[0043] Reference Figure 5 The difference between the building scaffolding support structure adapted to the exterior wall shape disclosed in this application and Embodiment 2 is that: In this embodiment, the docking component 6 includes a docking sleeve 62 and a return spring 63. The docking sleeve 62 is slidably sleeved on the outer peripheral wall of the free end of the rotating rod 25, and the return spring 63 is sleeved on the outer peripheral wall of the rotating rod 25. One end of the return spring 63 is fixedly connected to the docking sleeve 62, and the other end is fixedly connected to the outer peripheral wall of the rotating rod 25. Normally, the return spring 63 causes the docking sleeve 62 to partially move out of the end face of the rotating rod 25 away from the rotating ring 24, and causes the docking sleeve 62 to be sleeved on the outer peripheral wall of the free end of the adjacent rotating rod 25.

[0044] The implementation principle of Embodiment 3 of this application is as follows: Pulling the docking sleeve 62 forces the docking sleeve 62 to compress the return spring 63, so that the return spring 63 has elastic force. Then, the free ends of the two adjacent rotating rods 25 are rotated to a relative state (at this time, the lower limit sleeve 21 and the upper limit sleeve 22 are close to each other). Finally, the pulling effect of the docking sleeve 62 is released. Under the action of the return spring 63, the docking sleeve 62 is partially sleeved on the outer peripheral wall of the free end of the adjacent rotating rod 25, so that the two adjacent rotating rods 25 are connected as one, improving the convenience of connecting or separating the two rotating rods 25.

[0045] Example 4: This application discloses a building scaffolding support structure adapted to the shape of the exterior wall.

[0046] Reference Figure 6 , Figure 7 The difference between the building scaffolding support structure adapted to the exterior wall shape disclosed in this application and Embodiment 2 is that: In this embodiment, a triangular support frame 7 is installed on the first vertical rod 1. A connector 71 is installed between the triangular support frame and the multiple first vertical rods 1. The triangular support frame 7 is detachably installed between the multiple first vertical rods 1 through the multiple connectors 71. In this embodiment, the connector 71 includes a connecting sleeve 711 and a connecting bolt 712. The outer peripheral wall of the connecting sleeve 711 is welded and fixed to the side wall of the triangular support frame 7. The connecting sleeve 711 is slidably sleeved on the outer peripheral wall of the first vertical rod 1. A connecting hole communicating with the inside of the connecting sleeve 711 is opened on the outer peripheral wall of the connecting sleeve 711. The connecting bolt 712 passes through the connecting hole and abuts against the outer peripheral wall of the first vertical rod 1. The connecting bolt 712 is threadedly connected to the inner peripheral wall of the connecting hole.

[0047] Reference Figure 7 , Figure 8A protective frame 8 is installed on the side of the triangular support frame 7 away from the first vertical rod 1. The protective frame 8 is spaced apart from the building facade to form a safety protection zone 81 for personnel to work on the edge. The protective frame 8 includes multiple horizontally and vertically arranged protective rods 84, which are hollow. A plug-in post 72 is vertically installed on the side of the triangular support frame 7 away from the first vertical rod 1. The plug-in post 72 is used to insert into one end of the protective rod 84. A first fixing hole is opened on the outer peripheral wall of the protective rod 84, and a second fixing hole is opened on the outer peripheral wall of the plug-in post 72, which is opposite to the first fixing hole. The protective rod 84 is equipped with fixing bolts 841, which are sequentially inserted into the first fixing hole and the second fixing hole and threadedly connected to the second fixing hole to connect the protective frame 8 with the triangular support frame 7. It should be noted that during actual construction, a footboard (not shown in the figure) needs to be placed on the top wall of the triangular support frame 7 for personnel to step on.

[0048] Reference Figure 7 , Figure 8 A reinforcing plate 83 is installed on the side of the protective frame 8 away from the rotating ring 24. A clamping member is installed between the reinforcing plate 83 and the protective frame 8. The reinforcing plate 83 is detachably installed on the protective frame 8 via the clamping member. In this embodiment, the clamping member is set as a clamping ring 85. The clamping ring 85 is elastically set and is used to fasten the protective rod 84 of the protective frame 8. The clamping ring 85 is fixedly installed on the side wall of the reinforcing plate 83 near the protective frame 8. The outer peripheral wall of the clamping ring 85 has an inlet and outlet 851 for the protective rod 84 to enter and exit. A guide block 852 is integrally formed on the side wall of the clamping ring 85 at the inlet and outlet 851. The guide block 852 is used for the protective rod 84 to abut against, so that the clamping ring 85 deforms and expands the inlet and outlet 851. The guide block 852 has a guide surface 853. The inner diameter of the clamping ring 85 in this application is adapted to the inner diameter of the protective rod 84, and the clamping ring 85 can slide along the length direction of the protective rod 84.

[0049] Reference Figure 7 , Figure 8 A mounting post 241 is fixedly installed on the upper surface of the rotating ring 24. A reinforcing rod 82 is installed between the reinforcing plate 83 and the rotating ring 24. One end of the reinforcing rod 82 is rotatably connected to the side wall of the reinforcing plate 83 near the protective frame 8. The other end of the reinforcing rod 82 has a mounting hole 821 for the mounting post 241 to be inserted. The end of the reinforcing rod 82 away from the reinforcing plate 83 is rotatably connected to the rotating ring 24 through the mounting post 241. When the lower limit sleeve 21 and the upper limit sleeve 22 approach each other (i.e., after the two adjacent rotating rods 25 are connected), the rotating ring 24 pulls the reinforcing rod 82 through the mounting post 241, and the reinforcing rod 82 exerts a tension on the protective frame 8.

[0050] The implementation principle of Embodiment 4 of this application is as follows: The protective frame 8 serves to shield and protect, thereby improving the safety of personnel during construction. The two adjacent rotating rods 25 are rotated so that their free ends are opposite each other, and are limited by the connecting rod 61. At this time, the lower limit sleeve 21 and the upper limit sleeve 22 approach each other to abut against the second vertical rod 2, thereby fixing the second vertical rod 2. During the rotation of the rotating ring 24 driven by the rotating rod 25, the rotating ring 24 pulls the reinforcing rod 82 through the mounting column 241 to tighten it against the protective frame 8, thereby improving the connection stability between the protective frame 8 and the overall structure and improving work safety.

[0051] 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.
