Description

Technical Field

[0001] This application relates to the technical field of building safety nets, and in particular to a building perimeter safety net. Background Technology

[0002] Construction safety nets, also known as climbing scaffold nets, are mainly used to protect against falls from heights when installed on horizontal or vertical surfaces during the construction of high-rise buildings.

[0003] In the prior art, there is a building perimeter protective netting, which includes a climbing frame arranged circumferentially on the outer perimeter of the building and a support frame covering the outside of the climbing frame to surround the building, with a net covering the support frame.

[0004] Regarding the aforementioned technologies, in the construction environment, the mesh is easily corroded or damaged. When the mesh is damaged, the existing technology requires disassembling the connection between the mesh and the support frame point by point, and removing the entire mesh from top to bottom for replacement, which is quite troublesome. Summary of the Invention

[0005] To address the cumbersome method of replacing mesh in existing technologies, this application provides a safety net for the perimeter of buildings.

[0006] The following technical solution is adopted:

[0007] A safety net for the perimeter of a building, comprising:

[0008] Several fixed frames are interconnected and cover the outer perimeter of the building body along the direction of gravity;

[0009] A plurality of release tubes are connected to the end of the corresponding fixed frame away from the ground, including a first tube body, a first winding rod and a mesh cloth. The first winding rod is rotatably connected to the tube body. One end of the mesh cloth is wound onto the first winding rod, and the other end extends out of the tube body towards the ground.

[0010] Several fabric take-up tubes are connected to the end of the corresponding fixed frame near the ground, including a second tube body and a second roll rod. The second roll rod is rotatably connected to the second tube body. The end of the net fabric away from the first roll rod passes through the second tube body and is wound onto the second roll rod.

[0011] Several pressing frames are arranged parallel to the fixed frame. The pressing frame is slidably connected between the release tube and the take-up tube. After the pressing frame can slide, it presses the mesh fabric onto the fixed frame.

[0012] Several control components are disposed on the release tube for controlling the movement of the pressing frame.

[0013] By adopting the above technical solution, the release tube releases the mesh fabric, and the take-up tube collects the mesh fabric. After the mesh fabric is damaged, the second coil is used to rewind the mesh fabric until the damaged part enters the take-up tube, thereby forming a new mesh fabric cover. The mesh fabric is then pressed onto the fixed frame by the pressing frame, thus providing a convenient roll-changing method.

[0014] Optionally, the fixing frame includes a fixed outer frame and several fixed inner frames. The array of several fixed inner frames is connected to the fixed outer frame to divide the space inside the fixed outer frame into several small sections. One end of the fixed outer frame is connected to the release tube, and the other end is connected to the take-up tube.

[0015] By adopting the above technical solution, the fixing frame of the inner frame is divided into several small sections, so that the contact surface between the fixing frame and the mesh is as large as possible, and the support of the fixing frame for the mesh is more stable.

[0016] Optionally, the pressing frame includes a pressing outer frame and several pressing inner frames. The pressing outer frame corresponds to the shape and position of the fixed outer frame. Several pressing inner frames are arrayed inside the pressing outer frame to divide the space inside the pressing outer frame into several small sections. An X-shaped reinforcing rod is provided inside the pressing inner frame.

[0017] By adopting the above technical solution, the pressing outer frame corresponds to the fixed outer frame, so that the edge of the mesh is pressed and fixed. The pressing inner frame corresponds to the fixed inner frame, so that the area of ​​the mesh being clamped is as large as possible, and the connection between the mesh and the fixed frame is more stable. The reinforcing rod of the X-shaped structure provides support for the part of the mesh in the pressing inner frame area, thereby improving the structural stability of the mesh.

[0018] Optionally, the pressing frame is provided with a first pressing strip at one end near the release tube, and the fixing frame is provided with a first fixing strip at one end corresponding to the first pressing strip. The first pressing strip is provided with a plurality of first main protrusions and first main grooves interlaced along the length direction. The first fixing strip is provided with a first secondary groove corresponding to the first main protrusion and a first secondary protrusion corresponding to the first main groove along the length direction.

[0019] By adopting the above technical solution, the mesh fabric is clamped by the cooperation of the first pressing strip and the first fixing strip, and the cooperation of the protrusion and the groove increases the stability of the mesh fabric connection.

[0020] Optionally, one end of the pressing frame extends into the first tube and is provided with a cutting element. A blade block is provided on the tube wall of the first tube at a position corresponding to the cutting element. The mesh is located between the blade block and the cutting element, and the end of the cutting element near the mesh is a pointed tip.

[0021] By adopting the above technical solution, once the mesh is released to the appropriate position, it can be fixed by the pressing frame and cut, which facilitates the recycling and replacement of the mesh roll and avoids placing new mesh in the release tube for a long time, thus affecting its service life.

[0022] Optionally, the pressing frame is provided with a second pressing strip at one end near the take-up tube, and the fixing frame is provided with a second fixing strip at one end corresponding to the second pressing strip. The second pressing strip is provided with a plurality of second main protrusions and second main grooves interlaced along the length direction. The second fixing strip is provided with a second secondary groove corresponding to the second main protrusion and a second secondary protrusion corresponding to the second main groove along the length direction.

[0023] Optionally, the control component includes a screw and several balance bars. The screw is rotatably connected to the inside of the release tube perpendicular to its length. A vertically oriented groove is formed on the outer wall of the release tube. One end of the pressing frame is provided with a slider that passes through the groove and enters the release tube. The screw passes through the slider and is threadedly connected to it. The balance bars are arranged parallel to the screw inside the release tube. Several balance grooves parallel to the groove are formed on the outer wall of the release tube. One end of the pressing frame is provided with a groove that passes through the balance groove and enters the release tube, and is slidably connected to the balance bars.

[0024] By adopting the above technical solution, a method for driving the pressing frame to move is provided. The screw rotation drives the slider to move along its length direction, and the balance bar is used to stabilize the pressing frame, so that the pressing frame can move smoothly.

[0025] Optionally, the inner wall of the release tube is provided with a rotation drive component, the output end of the rotation drive component is provided with a driving helical gear, and the screw is coaxially provided with a driven helical gear that meshes with the driving helical gear.

[0026] Optionally, the protective netting may also include a protective frame for workers to climb, with one side of the protective frame connected to the building structure and the other side connected to the fixed frame.

[0027] Optionally, the first tube body has a first placement groove vertically formed on the tube wall at both ends for mounting the first coil rod, with the opening of the first placement groove facing upwards. The second tube body has a second placement groove formed on the tube wall at both ends for placing the second coil rod, with the second placement groove being inverted J-shaped and the end of the second placement groove away from the arc edge extending outwards.

[0037] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 This application will be described in further detail.

[0038] Reference Figure 1 and Figure 2This application discloses a safety net for the outer perimeter of a building. The safety net includes: a protective frame 1, several fixed frames 2, several release tubes 3, several take-up tubes 4, and several pressing frames 5. The protective frame 1 is installed on the outer perimeter of the building 7 for workers to climb. The protective frame 1 is generally made of bamboo, wood, or steel to form a frame for support. One side of the protective frame 1 is connected to the building 7, and the other side is connected to the fixed frames 2. The fixed frames 2 are long rectangular frames, connected to the outside of the protective frame 1 along the direction of gravity. The fixed frames 2 abut against each other and are sequentially connected to cover the outer perimeter of the protective frame 1, forming a protective net. The release tubes 3 are connected to the ends of the corresponding fixed frames 2 away from the ground. The release tubes 3 include a first tube body 31, a first coiled rod 32, and a mesh 33. The release tubes 3 are hollow tubes closed at both ends. The first coil rod 32 is rotatably connected to the first tube 31. One end of the mesh fabric 33 is wound onto the first coil rod 32, and the other end extends out of the tube towards the ground. The take-up tube 4 is connected to the end of the corresponding fixed frame 2 near the ground. The take-up tube 4 includes a second tube 41 and a second coil rod 42. The second coil rod 42 is rotatably connected to the second tube 41. The end of the mesh fabric 33 away from the first coil rod 32 passes through the second tube 41 and is wound onto the second coil rod 42. The pressing frame 5 is arranged parallel to the fixed frame 2. The pressing frame 5 is slidably connected between the release tube 3 and the take-up tube 4. After the pressing frame 5 can slide, it presses the mesh fabric 33 onto the fixed frame 2. The protective net also includes a control component 6 disposed on the release tube 3 for controlling the movement of the pressing frame 5. The release tube 3 releases the mesh 33, and the take-up tube 4 takes in the mesh 33. After the mesh 33 is damaged, the second winding rod 42 is used to wind up the mesh 33 until the damaged part enters the take-up tube 4, thereby forming a new mesh 33 covering it. The mesh 33 is then pressed onto the fixed frame 2 by the pressing frame 5, thus providing a convenient way to change the roll.

[0039] Reference Figure 1 and Figure 2 Furthermore, the fixing frame 2 includes a fixed outer frame 21 and several fixed inner frames 22. The several fixed inner frames 22 are arrayed and connected inside the fixed outer frame 21, dividing the space inside the fixed outer frame 21 into several small sections. One end of the fixed outer frame 21 is connected to the release tube 3, and the other end is connected to the take-up tube 4. By dividing the fixing frame 2 into several small sections through the fixed inner frames 22, the contact surface between the fixing frame 2 and the mesh fabric 33 is maximized, making the support of the fixing frame for the mesh fabric 33 more stable.

[0040] Reference Figure 1 and Figure 2Furthermore, the pressing frame 5 includes a pressing outer frame 51 and several pressing inner frames 52. The pressing outer frame 51 corresponds to the fixed outer frame 21 in shape and position. The several pressing inner frames 52 are arrayed and connected inside the pressing outer frame 51, dividing the space inside the pressing outer frame 51 into several small sections. X-shaped reinforcing rods 53 are provided inside the pressing inner frames 52. The pressing outer frame 51 corresponds to the fixed outer frame 21, so that the edges of the mesh fabric 33 are pressed and fixed. The pressing inner frames 52 correspond to the fixed inner frame 22, so that the area where the mesh fabric 33 is clamped is as large as possible, making the connection between the mesh fabric 33 and the fixed frame more stable. The X-shaped reinforcing rods 53 provide support for the portion of the mesh fabric 33 within the pressing inner frame 52 area, thereby improving the structural stability of the mesh fabric 33.

[0041] Reference Figures 2 to 4 Furthermore, a first pressing strip 54 is provided at one end of the pressing frame 5 near the release tube 3, and a first fixing strip 23 corresponding to the first pressing strip 54 is provided at one end of the fixing frame 2.

The first fixing strip 23 has a first secondary groove 231 corresponding to the first main protrusions 541 and a first secondary protrusion 232 corresponding to the first main grooves 542 along its length. Through the cooperation of the first pressing strip 54 and the first fixing strip 23, the mesh fabric 33 is clamped, and the cooperation of the protrusions and grooves increases the stability of the mesh fabric 33 connection.

[0042] Reference Figures 2 to 4 Furthermore, one end of the pressing frame 5 extends into the first tube 31 and is equipped with a cutting element 55. A blade-holding block 311 is positioned on the wall of the first tube 31 corresponding to the cutting element 55. The mesh fabric 33 is located between the blade-holding block 311 and the cutting element 55, with the end of the cutting element 55 near the mesh fabric 33 being a pointed tip. When the mesh fabric 33 is released to a suitable position, it can be fixed by the pressing frame 5 and cut, facilitating the recycling and replacement of the mesh fabric roll and avoiding the long-term storage of new mesh fabric 33 inside the release tube 3, which would affect its service life.

[0043] Reference Figures 2 to 4 Furthermore, a second pressing strip 56 is provided at one end of the pressing frame 5 near the receiving tube 4, and a second fixing strip 24 is provided at one end of the fixing frame 2, which is located at the position corresponding to the second pressing strip 56. The second pressing strip 56 is provided with a plurality of second main protrusions 561 and second main grooves 562 interlaced along the length direction. The second fixing strip 24 is provided with a second secondary groove 241 corresponding to the second main protrusion 561 and a second secondary protrusion 242 corresponding to the second main groove 562 along the length direction.

[0044] Reference Figures 2 to 4Furthermore, the control component 6 includes a screw 61 and several balance bars 62. The screw 61 is rotatably connected to the release tube 3 along its length. The outer wall of the release tube 3 has a vertically oriented groove 34. One end of the pressing frame 5 is provided with a slider 57 that passes through the groove 34 and enters the release tube 3. The screw 61 passes through the slider 57 and is threadedly connected to the slider 57. The balance bars 62 are parallel to the screw 61 and are provided in the take-up tube 4. The outer wall of the take-up tube 4 has several balance grooves 43 that are parallel to the groove 34. One end of the pressing frame 5 is provided with a balance block 58 that passes through the balance groove 43 and enters the release tube 3. The balance bars 62 pass through the balance block 58, so that the two are slidably connected. Lubricating oil can be applied to the inside of the balance block 58 to increase the smoothness of the pressing frame 5 when sliding. A scheme is provided to drive the pressing frame 5 to move. The screw 61 rotates, causing the slider 57 to move along its length. The balance bar 62 is used to stabilize the pressing frame 5, allowing the pressing frame 5 to move smoothly. In addition, the take-up tube 4 is also provided with the same balance groove 43, and the take-up tube 4 is also provided with a balance bar 62. The end of the pressing frame 5 near the take-up tube 4 is also provided with several balance blocks 58 that can be slidably connected to the corresponding balance bars 62.

[0045] Reference Figures 2 to 4 Furthermore, a rotation drive 63 is provided on the inner wall of the release tube 3, and a driving helical gear 631 is provided at the output end of the rotation drive 63. A driven helical gear 611 that meshes with the driving helical gear 631 is provided on the screw 61 coaxially.

[0046] Reference Figures 2 to 4 Furthermore, the first tube 31 has a first placement groove 312 vertically opened on the tube wall at both ends for mounting the first coil rod 32. The first placement groove 312 opens upward. The second tube 41 has a second placement groove 411 for mounting the second coil rod 42 on the tube wall at both ends. The second placement groove 411 is in the shape of an inverted J, and the end of the second placement groove 411 away from the arc edge is set outward.

[0047] The implementation principle of a building perimeter safety net according to an embodiment of this application is as follows:

[0048] A protective frame 1 is erected on the exterior facade of the building. Several fixed frames 2 are sequentially connected to the outside of the protective frame 1 to form a perimeter enclosure of the building. One end of the mesh fabric 33 is connected to the release tube 3 and wound onto the first roll rod 32. The other end extends vertically downward into the take-up tube 4 and is wound onto the second roll rod 42, covering the fixed frames 2. The pressing frame 5 presses the mesh fabric 33 tightly onto the fixed frames 2 from the outside in, thus forming perimeter protection for the building. When the mesh fabric 33 is damaged, the pressing frame 5 is moved away from the mesh fabric 33, and the old mesh fabric 33 is removed. The mesh fabric 33 is released from the release tube 3, and a weight is suspended from one end of the mesh fabric 33. Under the action of gravity, the weight is lowered, and one end of the mesh fabric 33 is connected to the second roll rod 42. The second roll rod 42 is rotated to move the mesh fabric 33 and keep it flat. The pressing frame 5 is moved to press the new mesh fabric 33 onto the fixed frames 2, forming a new mesh fabric 33 protection. At the same time, one end of the mesh fabric 33 can be cut off to facilitate the recycling of the roll of mesh fabric 33.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
