Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to a scaffolding for building exterior wall construction. Background Technology

[0002] Scaffolding is a temporary construction tool erected on construction sites to facilitate worker operations and solve vertical and horizontal transportation. It is mainly used for exterior walls, interior decoration, or places where the floor height is too high for direct construction. It is mainly used for construction workers to move up and down, for the maintenance of external safety nets, and for the installation of components at height. Its materials usually include bamboo, wood, steel pipes, or composite materials. In the renovation of old buildings, when it is necessary to construct the exterior facade, due to the height of the building, multiple sets of scaffolding are usually required to be erected to form a temporary construction platform for construction.

[0003] Because of the height of the scaffolding, protective components need to be installed on the outside of the scaffolding. The existing protective components are mostly composed of two sets of steel pipes that are arranged in a cross pattern and fixed to the support frame with screws. The connection process is cumbersome, which affects the safety of construction. In addition, the protective area is small and there are large gaps, which cannot effectively protect the workers.

[0004] Therefore, it is necessary to invent a scaffold for building exterior wall construction to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a scaffold for building exterior wall construction, in order to solve the problems of existing protective components having a cumbersome connection process, affecting construction safety, and having a small protective area with large gaps, which cannot effectively protect workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scaffold for building exterior wall construction, comprising scaffold horizontal bars, wherein two sets of threaded columns are fixedly connected to the upper surface of the scaffold horizontal bars, and a protective frame is provided between the upper and lower sets of the scaffold horizontal bars. The protective frame includes a first protective bar, a second protective bar, a third protective bar, a fourth protective bar, a connecting shaft, a first fixed bar, a telescopic bar, a first overlapping plate, a first slot, a second fixed bar, a telescopic cylinder, a second overlapping plate, and a second slot.

[0007] By adopting the above technical solution, the first, second, third, and fourth protective rods, along with the connecting shaft, cooperate to allow the protective frame to be stretched and unfolded or retracted and folded. Through the cooperation of the first fixing rod, the first overlapping plate, the second fixing rod, the second overlapping plate, and the threaded column, the protective frame can be quickly fixed between the upper and lower sets of scaffold crossbars, improving the convenience and safety of installation. At the same time, the cooperation of multiple sets of protective rods effectively reduces gaps, improves the protective effect, and facilitates folding and transportation, improving the convenience of movement.

[0008] Optionally, the first protective rod and the second protective rod are rotatably connected at the middle, the first protective rod is rotatably connected to both ends of the second protective rod, and the second protective rod is rotatably connected to both the left and right ends of the second protective rod.

The rear ends of the connecting shafts at the right end of the first guard rod and the left end of the second guard rod are respectively fixedly connected to the surfaces of the two sets of first fixing rods, and the rear ends of the connecting shafts at the left end of the first guard rod and the right end of the second guard rod are respectively fixedly connected to the surfaces of the two sets of second fixing rods.

[0012] By adopting the above technical solution, during the unfolding or folding of the first, second, third, and fourth protective rods, the two sets of first and second fixed rods will be driven to separate or move closer to each other, thereby adjusting the distance between the two sets of first and second fixed rods.

[0013] Optionally, the first overlapping plate is fixedly connected to the upper end of the first fixing rod, and the first slot is formed on the surface of the first overlapping plate; the second overlapping plate is fixedly connected to the lower end of the second fixing rod, and the second slot is formed on the surface of the second overlapping plate.

[0014] By adopting the above technical solution, the first lap plate and the second lap plate are respectively placed on the surfaces of the upper and lower sets of scaffold crossbars, and the threaded column is inserted into the first slot and the second slot to fix the first lap plate and the second lap plate.

[0019] Optionally, the upper end of the first fixing rod is provided with a plug hole, and the lower end of the second fixing rod is fixedly connected with a plug rod, which is plugged into the plug hole for fixation.

[0020] By adopting the above technical solution, during the installation of the upper and lower protective frames, the plug-in rod on the surface of the second fixed rod in the upper protective frame is inserted into the plug-in hole on the surface of the first fixed rod in the lower protective frame, thereby improving the stability of the connection between the upper and lower protective frames.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. This utility model uses a first fixing rod, a first overlapping plate, a second fixing rod, a second overlapping plate, and a threaded column to quickly fix the protective frame between the upper and lower sets of scaffold crossbars, improving the convenience and safety of installation.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1 to 5 The scaffolding for building exterior wall construction shown includes scaffolding horizontal bars 1. The upper surface of the scaffolding horizontal bars 1 is fixedly connected with two sets of threaded columns 11 on the left and right sides. A protective frame 2 is set between the upper and lower sets of scaffolding horizontal bars 1. The protective frame 2 includes a first protective bar 21, a second protective bar 22, a third protective bar 23, a fourth protective bar 24, a connecting shaft 25, a first fixing bar 26, a telescopic bar 261, a first overlapping plate 264, a first slot 265, a second fixing bar 27, a telescopic cylinder 271, a second overlapping plate 274, and a second slot 275. The first fixing bar 26 overlaps the surface of the upper scaffolding horizontal bar 1, and the second fixing bar 27 overlaps the surface of the lower scaffolding horizontal bar 1.

[0033] The protective frame 2 is made of aluminum alloy, which is lightweight and strong. It provides strong protection while being easy to carry and transport. During installation, multiple sets of scaffold horizontal bars 1 and vertical bars are spliced ​​and fixed to form the scaffold. Then, a temporary construction platform is installed on the surface of the scaffold. After that, the protective frame 2 is unfolded and installed on the outside of the scaffold to protect the construction workers.

[0034] See Figure 2 and Figure 3The first protective rod 21 and the second protective rod 22 are rotatably connected at the middle. The first protective rod 21 is rotatably connected to both ends of the second protective rod 22. The second protective rod 22 is rotatably connected to both ends of the second protective rod 24. The third protective rod 23 and the fourth protective rod 24 on the same side are rotatably connected at their outer ends. The first protective rod 21, the second protective rod 22, the third protective rod 23 and the fourth protective rod 24 are rotatably connected to the connection points of the first protective rod 21, the second protective rod 22, the third protective rod 23 and the fourth protective rod 24. The first protective rod 21 and the second protective rod 22 are provided with two sets of first fixed rods 26 and second fixed rods 27 on their rear sides. The rear ends of the connecting shafts 25 at the right end of the first protective rod 21 and the left end of the second protective rod 22 are fixedly connected to the surfaces of the two sets of first fixed rods 26, respectively. The rear ends of the connecting shafts 25 at the left end of the first protective rod 21 and the right end of the second protective rod 22 are fixedly connected to the surfaces of the two sets of second fixed rods 27, respectively.

[0035] Specifically, the center of the first protective rod 21 and the center of the second protective rod 22 rotate around the central connecting shaft 25, the third protective rod 23 rotates around the connecting shafts 25 at both ends of the first protective rod 21, and the fourth protective rod 24 rotates around the connecting shafts 25 at both ends of the second protective rod 22. The third protective rod 23 and the fourth protective rod 24 rotate around the connecting shafts 25 at the outer ends, so that the protective frame 2 can be stretched and unfolded or folded and contracted. During transportation, the left and right ends are squeezed inward to fold the protective frame 2. Conversely, during installation, the left and right ends are stretched to the sides to unfold the protective frame 2.

[0036] See Figures 3 to 5 The first overlapping plate 264 is fixedly connected to the upper end of the first fixing rod 26. The first slot 265 is opened on the surface of the first overlapping plate 264. The second overlapping plate 274 is fixedly connected to the lower end of the second fixing rod 27. The second slot 275 is opened on the surface of the second overlapping plate 274. The telescopic rod 261 is fixedly connected to the lower end of the first fixing rod 26. The telescopic cylinder 271 is fixedly connected to the upper end of the second fixing rod 27. The telescopic rod 261 and the telescopic cylinder 271 are slidably connected. The surface of the telescopic rod 261 is provided with a locking hole 262. The surface of the telescopic cylinder 271 is provided with a threaded hole 272. The threaded hole 272 is internally threaded with a locking screw 276. The upper end of the first fixing rod 26 is provided with a plug-in hole 263. The lower end of the second fixing rod 27 is fixedly connected with a plug-in rod 273. The plug-in rod 273 is plugged into the plug-in hole 263 for fixation.

[0037] In addition, when the protective frame 2 is folded and retracted, the telescopic rod 261 will slide upward inside the telescopic cylinder 271. When the protective frame 2 is stretched and unfolded, the telescopic rod 261 will slide into the telescopic cylinder 271 until the telescopic rod 261 slides to the bottom of the telescopic cylinder 271. At this time, the locking hole 262 is located inside the threaded hole 272. Then, the locking screw 276 is tightened inward so that one end of it is locked inside the locking hole 262, thereby locking and fixing the telescopic rod 261 and the telescopic cylinder 271, thus fixing the protective frame 2. At this time, the protective frame 2 cannot be retracted or stretched, thus improving its stability.

[0038] At the same time, after unfolding the protective frame 2, the first overlapping plate 264 is directly hung on the surface of the upper scaffold crossbar 1, and the second overlapping plate 274 is hung on the surface of the lower scaffold crossbar 1. The threaded posts 11 on both sides of the upper side are respectively inserted into the first slot 265 and the second slot 275 to clamp and fix the positions of the first overlapping plate 264 and the second overlapping plate 274, thereby fixing the position of the protective frame 2.

[0039] Furthermore, during the installation of the upper protective frame 2, when the second overlapping plate 274 of the upper protective frame 2 is hung on the surface of the lower scaffold crossbar 1, it will press down on the upper side of the first overlapping plate 264 of the lower protective frame 2. The upper protective frame 2 presses down on the lower protective frame 2, effectively preventing the protective frame 2 from falling off. Therefore, no additional fixing is required for the protective frame 2, which effectively improves the ease of installation. In addition, the plug-in rod 273 on the surface of the second fixing rod 27 in the upper protective frame 2 will be inserted into the plug-in hole 263 on the surface of the first fixing rod 26 in the lower protective frame 2, so that multiple sets of protective frames 2 are connected into a whole, effectively improving the structural strength of the protective frame 2.

[0040] The working principle of this utility model is as follows: Through the cooperation of the first fixing rod 26, the first overlapping plate 264, the second fixing rod 27, the second overlapping plate 274 and the threaded column 11, the protective frame 2 can be quickly fixed between the upper and lower sets of scaffold crossbars 1, improving the convenience and safety of installation. The cooperation of multiple sets of protective rods effectively reduces gaps and improves the protective effect. At the same time, the cooperation of the first protective rod 21, the second protective rod 22, the third protective rod 23, the fourth protective rod 24 and the connecting shaft 25 allows the protective frame 2 to be stretched and unfolded or folded and retracted, improving the protective effect while facilitating folding and transportation, and improving the convenience of movement.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
