Description

Technical Field

[0001] This utility model relates to the field of exterior wall construction technology, specifically to a safety protection device for exterior wall construction of high-rise residential buildings. Background Technology

[0002] In the construction of the exterior walls of high-rise residential buildings, safety protection mainly relies on the coordinated operation of cantilevered scaffolding and metal planks: the scaffolding is mainly made of steel and is firmly connected to the wall through embedded parts to form a stable operating platform and is equipped with protective nets. The planks are mostly made of galvanized steel or aluminum alloy, with anti-slip holes and reinforcement structures on the surface. They not only support workers and materials, but also ensure safety through standardized installation.

[0003] When decorating exterior walls, in order to improve construction efficiency, workers often temporarily place construction materials such as tiles on top of scaffolding steps for easy access. However, when stacking materials on the steps, they are easily unstable and may fall from a height. Therefore, a safety protection device for exterior wall construction of high-rise residential buildings is proposed to solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4 As shown, a safety protection device for the construction of exterior walls of high-rise residential buildings includes scaffolding boards 1, with a limiting mechanism 2 installed on one side of the scaffolding boards 1. The limiting mechanism 2 includes a shelf 201, with a vertical frame 204 fixedly installed on the side of the shelf 201. A handrail 205 is fixedly connected to the top of the vertical frame 204. The vertical frame 204 extends vertically as a whole. A lifting block 207 is fitted on the outer wall of the vertical frame 204. A sliding hole 208 is opened in the middle of the lifting block 207. The inner side of the sliding hole 208 is slidably connected along the vertical frame 204. A limiting groove 209 is opened in the middle of the outer wall of the lifting block 207. A rotating plate 213 is fitted and rotatably connected to the inner side of the limiting groove 209. A telescopic plate 214 is slidably connected to the inner wall of the rotating plate 213. Both the rotating plate 213 and the telescopic plate 214 extend horizontally. Figure 4 As shown, a limiting end plate is provided at the end of the telescopic plate 214 to prevent the telescopic plate 214 from completely detaching from the inside of the rotating plate 213.

[0018] The telescopic plate 214, located at the end furthest from the rotating plate 213, has a threaded rod 215 connected through it. A knob 216 is fixedly connected to the top of the threaded rod 215, and a pressure plate 217 is fixedly connected to the bottom of the threaded rod 215. Figure 3 As shown, a non-slip rubber pad is bonded to the bottom surface of pressure plate 217.

[0019] An extension plate 210 is fixedly connected to the top surface of the lifting block 207 near the sliding hole 208. A pin 211 is threaded through the middle of the extension plate 210. An anti-slip sleeve 212 is glued and fixed to the outside of the pin 211. The outer wall of the anti-slip sleeve 212 is slidably connected to and abuts against the extension plate 210. Figures 1-3As shown, the anti-slip sleeve 212 is made of rubber, which increases the friction between the pin 211 and the extension plate 210 and the socket 206, preventing the pin 211 from easily loosening.

[0020] The bottom surface of the shelf 201 is symmetrically and fixedly connected with threaded posts 202. Each threaded post 202 is perpendicular to the bottom surface of the shelf 201, and a nut 203 is threaded onto the outer side of each threaded post 202. Several insertion holes 206 are provided on the side of the upright 204 near the lifting block 207. Each insertion hole 206 is equidistant along the length of the upright 204. The insertion holes 206 are connected to pins 211, and the inner wall of the insertion holes 206 is slidably connected to an anti-slip sleeve 212. Figures 1-3 As shown, the position of the lifting block 207 on the upright 204 is fixed by the pin 211.

[0021] The scaffolding platform 1 includes a platform body 101, with hooks 102 fixedly installed around its circumference. Several anti-slip holes 103 are formed on the surface of the platform body 101. The sides of the platform body 101 are supported and connected to a shelf 201. The bottom surface of the platform body 101 abuts against each nut 203. The inner sides of the anti-slip holes 103 are connected to threaded posts 202. Figure 1 As shown, fasteners or connecting ropes can be inserted into the anti-slip hole 103 to facilitate connection and fixation with the scaffolding.

[0022] The working principle of this utility model: When the device is in use, the shelf 201 can be pressed against the edge of the pedal body 101, and the threaded post 202 can be passed through the anti-slip hole 103. Then, the nut 203 is installed at the end of the threaded post 202 and tightened. The top surface of the nut 203 presses against the bottom surface of the pedal body 101 and is clamped and fixed with the shelf 201. After that, the pedal body 101 can be installed on the scaffold with the hook 102 and fasteners. Secondly, when it is necessary to temporarily store the construction board above the pedal body 101, the board can be placed on the top of the shelf 201. After the pin 211 is pulled out of the insertion hole 206, the lifting block 207 moves up and down along the upright 204. The lifting block 207 drives the rotating plate 213 to move above the board and pushes the pin 211 into the nearby insertion hole 206 to complete the fixation. Then, the rotating plate 213 is rotated around the lifting block 207 until the pressure plate 217 moves above the board. Then, the screw 215 is rotated by the knob 216, the screw 215 is pressed by the thread and the pressure plate 217 is driven to fall. The pressure plate 217 can press down and position the top surface of the board, thereby preventing the board from falling from above the pedal body 101.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
