Description

Technical Field

[0001] This utility model relates to the field of building construction protection technology, specifically a protective net installation support for exterior wall renovation. Background Technology

[0002] With urbanization, land resources are becoming increasingly scarce, leading to a continuous increase in building height. In high-rise construction, the installation of safety nets on building exterior walls is crucial, playing a vital role in construction safety. Currently, common horizontal safety nets on building exteriors are typically installed using steel pipes. While this method is convenient due to readily available materials, it also presents disadvantages. As buildings grow taller, the installation height increases, making installation and dismantling difficult and posing safety hazards. Furthermore, the steel pipes need to be transported between floors, which is inconvenient. The construction period is long, the workload at height is substantial, the work is dangerous, and the efficiency and labor intensity are low. Therefore, we propose a new type of safety net installation support for exterior wall renovations. Utility Model Content

[0029] Please see Figures 1-5 This utility model proposes a protective net installation support for exterior wall renovation, including an exterior wall body 1. An upper installation device 2 and a lower installation device 3 are fixedly connected to the outer wall of the exterior wall body 1. Through the cooperation of the upper installation device 2 and the lower installation device 3, the protective net body 4 can be installed and fixed. The protective net body 4 is arranged on the side of the lower installation device 3. The lower installation device 3 is provided with a limit rod 5 and a limit device 6. The front part of the outer wall of the limit rod 5 is provided with a threaded groove to facilitate the subsequent fixing of the protective net body 4 and the adjustment of its angle. The limit device 6 includes a ratchet 61, and the ratchet 61 is penetrated by the limit rod 5 and fixedly connected to the limit rod 5. The ratchet 61 is engaged with the elastic telescopic rod 62. The engagement of the ratchet 61 and the elastic telescopic rod 62 enables one-way limiting of the limiting rod 5, preventing it from rotating downwards and allowing it to rotate only upwards. Specifically, when the ratchet teeth of the ratchet 61 rotate downwards, they are limited by the telescopic end of the elastic telescopic rod 62. When the ratchet teeth of the ratchet 61 rotate upwards, the helical edge of the ratchet teeth compresses the telescopic end of the elastic telescopic rod 62, allowing the ratchet 61 to rotate normally. A pull rod 65 is provided on the side of the elastic telescopic rod 62. The outer wall of the telescopic end of the elastic telescopic rod 62 is hinged to a hinge rod 67, and the other end of the hinge rod 67 is hinged to the pull rod 65.

[0030] In this embodiment of the invention, in order to adjust and fix the angle of the protective net body 4, and to provide protection for the protective net body 4, specifically, a pull rod 65 passes through and is slidably connected to a fixing cylinder 63. A pad 64 is slidably connected to the inner wall of the fixing cylinder 63. The pad 64 is passed through and fixedly connected to the pull rod 65. The pad 64 is elastically connected to the inner wall of the fixing cylinder 63 by a spring 66. A connecting foot 41 is fixedly connected to the side of the protective net body 4 near the lower mounting device 3. The internal part is provided with a threaded hole. After the limiting rod 5 is rotated and inserted into the connecting foot 41, it can be threadedly connected to the connecting foot 41. During this process, first pull the lever 65 to drive the telescopic end of the elastic telescopic rod 62 to retract. After the limiting rod 5 is fully rotated and inserted into the connecting foot 41, the ratchet 61 rotates and moves above the elastic telescopic rod 62. Then release the lever 65 so that the telescopic end of the elastic telescopic rod 62 is reset and engaged with the ratchet 61, thereby achieving the fixed limit of the protective net body 4. After the engagement between the ratchet 61 and the elastic telescopic rod 62 is released, the angle of the protective net body 4 can be adjusted.

[0031] Furthermore, in order to install and fix the protective net body 4, specifically, the upper mounting device 2 includes an upper mounting plate 21, on the side of the upper mounting plate 21 away from the outer wall body 1, a first support plate 22 is fixedly connected, and a winding device 23 is fixedly connected to the upper side of the first support plate 22. The winding device 23 is an existing device that can drive the winding roller to rotate through a stepper motor, thereby realizing the winding and unwinding of the pull rope 24, which facilitates the subsequent angle adjustment of the protective net body 4. The pull rope 24 is wound on the outer wall of the winding device 23, and the end of the pull rope 24 away from the winding device 23 is fixedly connected to the protective net body 4. The lower mounting device 3 includes a lower mounting plate 31, on the side of the lower mounting plate 31 away from the outer wall body 1, a second support plate 22 is fixedly connected. The upper side of the second support plate 32 is fixedly connected to a limiting protective block 33. Through the use of the second support plate 32 and the limiting protective block 33, the protective net body 4 can be provided with secondary protection, further preventing the protective net body 4 from rotating and causing dangerous situations. The lower mounting plate 31 is fixedly connected to a support block 34 on the side away from the outer wall body 1. The inner wall of the support block 34 is penetrated by a tie rod 65 and is slidably connected to the tie rod 65. The inner wall of the support block 34 is fixedly connected to an elastic telescopic rod 62. By pulling the tie rod 65, the telescopic end of the elastic telescopic rod 62 is retracted, so that the elastic telescopic rod 62 releases the limit on the ratchet 61. Then, the winding device 23 is started, and the angle of the protective net body 4 can be adjusted.

[0032] In this utility model, when installing the protective net body 4, first insert the connecting foot 41 into the groove of the support block 34, then pull the pull rod 65 to retract the telescopic end of the elastic telescopic rod 62, then rotate the limiting rod 5. After the limiting rod 5 is fully rotated and inserted into the connecting foot 41, the ratchet 61 rotates and moves above the elastic telescopic rod 62. Then release the pull rod 65 to reset the telescopic end of the elastic telescopic rod 62 and engage with the ratchet 61, thereby achieving the fixed limiting of the protective net body 4. Then fix the pull rope 24 to the protective net body 4 to complete the installation of the protective net body 4.

[0033] Meanwhile, when it is necessary to adjust the angle of the protective net body 4, by pulling the pull rod 65, the telescopic end of the elastic telescopic rod 62 is retracted, so that the elastic telescopic rod 62 releases the limit on the ratchet 61, and then the winding device 23 is started to realize the winding and unwinding of the pull rope 24, thereby realizing the angle adjustment of the protective net body 4.

[0034] Meanwhile, when the pull rope 24 breaks, the elastic telescopic rod 62 engages with the ratchet 61, preventing the protective net body 4 from rotating downwards, thus protecting the protective net body 4 and preventing it from rotating uncontrollably and causing danger. When the limiting device 6 of the device is damaged and cannot limit the protective net body 4, the second support plate 32 and the limiting protection block 33 can provide secondary protection for the protective net body 4 when the pull rope 24 breaks, further preventing the protective net body 4 from rotating and causing danger.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
