[0032] It should be understood that the fixed length of the guardrail or baffle of the protective device makes it impossible to protect the building edges of different lengths. The fixed length of the guardrail or baffle means that a large number of models of protective devices need to be prepared to be applicable to building edges of different lengths, which in turn increases the cost.
[0033] To address the aforementioned issues, this embodiment discloses an edge protection device for construction. Please refer to [reference needed]. Figures 1 to 9 The edge protection device for construction in this embodiment mainly includes two columns and two first uprights. This device is mainly used to protect the edges of buildings of different lengths. The columns 1 can be rectangular, cylindrical, or other columnar structures; in this embodiment, the columns 1 are cylindrical. In this embodiment, a protective component 2 is provided between the two columns 1 to protect the building edges.
[0034] In this embodiment, as Figure 1As shown, both columns 1 have multiple circumferential protrusions 11 on their outer walls. The multiple circumferential protrusions 11 are arranged sequentially at intervals along the axial direction of the column 1. The number of circumferential protrusions 11 can be set according to factors such as the height of the circumferential protrusions 11 and the height of the column 1. In this embodiment, for ease of description, two circumferential protrusions 11 are used, and the two circumferential protrusions 11 are respectively located near the upper end and the lower end of the column 1.
[0035] In this embodiment, as Figure 1 As shown, two first uprights 3 can be respectively set on one side of two columns 1. The first uprights 3 are parallel to the axis of the columns 1. Multiple fixed sliders 31 are provided between the side wall of the first uprights 3 facing the columns 1 and the columns 1. The multiple fixed sliders 31 are arranged sequentially at intervals along the axis of the columns 1. The multiple fixed sliders 31 are detachably connected to multiple circumferential bosses 11, so that the first uprights 3 and the columns 1 are detachably connected, thereby making the transportation of the first uprights 3 and the columns 1 more convenient.
[0036] In this embodiment, as Figures 1-4 As shown, the first upright 3 has a first mounting groove 32 on its side wall away from the column 1, and the first mounting groove 32 is parallel to the axis of the column 1. The first mounting groove 32 is used to install the protective structure 4. Specifically, when the protective length of the protective component 2 is short and therefore cannot provide sufficient protection for the building edge, the two ends of the protective structure 4 are respectively installed into the two first mounting grooves 32 of the two columns 1 of the two edge protection devices used for construction. This increases the protection range of the edge protection device used for construction, thereby protecting the building edge with a larger length range. The shape of the first mounting groove 32 is consistent with that of the first upright 3. In this embodiment, the first mounting groove 32 is rectangular.
[0037] The protective structure 4 can be made of materials such as steel pipes, square timber, or wooden boards. In this embodiment, steel pipes are used as the protective structure 4. Multiple steel pipes are installed sequentially into the first mounting slots 32 of the two edge protection devices used for construction, thereby protecting the long building edge. Furthermore, since steel pipes are used on-site, the cost is lower. In addition, steel pipes of different lengths can be selected according to the length of the building edge, or the steel pipes can be cut, so that the device can be applied to building edges of different lengths.
[0038] In this embodiment, as Figure 1 , Figure 2 and Figure 6As shown, the upper and lower sidewalls of the circumferential boss 11 are both provided with annular grooves 111. The sidewall of the fixed slider 31 facing the column 1 has a groove 311 that matches the height of the circumferential boss 11. The upper and lower sidewalls of the fixed slider 31 are both provided with bolt holes 312. The circumferential boss 11 and the fixed slider 31 are slidably connected. Specifically, the upper and lower sidewalls of the fixed slider 31 are both provided with bolt holes 312. A bolt 6 with its inner end abutting in the annular groove is provided in the bolt hole. The bolt 6 passes through the bolt hole 312 and abuts against the annular groove 111, thereby making the first column 3 and the circumferential boss 11 detachably slidably connected through the annular groove 111 and the fixed slider 31. Through the bolt connection, the user can change the position of the first column 3 along the circumference of the annular groove 111, so that the edge protection device used for construction can protect the building edge with different bending angles, thus making the edge protection device used for construction have a wide range of applications.
[0039] Meanwhile, the first upright 3 is detachably connected to the circumferential boss 11, which makes the edge protection device used for construction more convenient to transport and less restricted by environmental conditions with limited transport space.
[0040] In this embodiment, as Figures 1-2 As shown, when the circumferential boss 11 is connected to the first upright 3, the upper and lower sidewalls of the fixed slider 31 are respectively attached to the upper and lower sidewalls of a portion of the circumferential boss 11, and the inner wall of the fixed slider 31 facing the upright 1 abuts against and is attached to the sidewall of the circumferential boss 11, thereby making the connection between the circumferential boss 11 and the fixed slider 31 relatively stable.
[0041] In this embodiment, as Figures 1-2 As shown, when the circumferential boss 11 is bolted to the first upright 3, the bolt holes 312 on the upper and lower sidewalls of the fixed slider 31 are located on the upper and lower sides of the upper and lower annular grooves 111 of the circumferential boss 11, respectively, so that one end of the bolt 6 abuts against the inner wall of the annular groove 111 in the vertical direction, thereby making the connection between the circumferential boss 11 and the first upright 3 stable.
[0042] In this embodiment, the building edge is protected by two columns 1 and a protective component 2, and the protection range of the edge protection device for construction is increased by the circumferential boss 11, the fixed slider 31, the first upright 3 and the first mounting groove with a protective structure thereon, so that the device is suitable for building edges of different lengths.
[0043] Among them, such as Figures 1-2 As shown, the lower end of the column 1 has multiple support blocks 5 on its outer wall. The multiple support blocks 5 are arranged sequentially and spaced apart along the circumference of the outer wall of the column 1. The support blocks 5 have fixing holes 51. When the column 1 is in use, the bolts 6 pass through the fixing holes 51 and are inserted into the ground to fix the column 1.
[0044] In some embodiments, such as Figures 3-5 As shown, a first fixing plate 33 is provided on one side of the inner wall opposite to the first mounting groove 32. Both first fixing plates 33 are parallel to the inner wall of the first mounting groove 32. Both first fixing plates 33 are rectangular and adapted to the first mounting groove 32. Both sides of the first upright 3 are provided with a first threaded rod 34 perpendicular to the side wall of the first upright 3. The first threaded rod 34 passes through the side wall of the first upright 3 and abuts against the side wall of the first fixing plate 33. The first threaded rod 34 is located at the center of the side wall of the first upright 3 in the vertical direction, and one end of the first threaded rod 34 abuts against the center of the first fixing plate 33. Thus, the first threaded rod 34 can be rotated to push the first fixing plate 33 against the outer wall of the protective structure 4 such as the steel pipe installed in the first mounting groove 32, thereby fixing the protective structure 4 such as the steel pipe.
[0045] In this embodiment, as Figures 3-5 As shown, two first limiting rods 35 are provided on both sides of the first upright 3. The two first limiting rods 35 on the same side are positioned opposite each other at the upper and lower ends of the first threaded rod 34. The axial direction of the first limiting rods 35 is consistent with the axial direction of the first threaded rod 34. One end of each of the two first limiting rods 35 passes through the side wall of the first upright 3 and is fixedly connected to the side wall of the first fixing plate 33, thereby stabilizing the position and displacement direction of the first fixing plate 33.
[0046] The first fixing plate 33 allows the first mounting groove 32 to install and fix protective structures 4 such as steel pipes and square timber of different sizes.
[0047] In this embodiment, as Figures 3-4 As shown, rubber pads 7 are provided on the opposite sides of the two first fixing plates 33, so that protective structures 4 with small size differences can be installed simultaneously in the first mounting groove 32.
[0048] In some embodiments, such as Figure 1 , Figure 2 and Figure 7 As shown, the protective component 2 includes multiple telescopic members 21 and two second uprights 22. The side walls of the two second uprights 22 are respectively connected to the two columns 1 through multiple telescopic members 21. The opposite side walls of the two second uprights 22 are provided with second mounting grooves 221 for installing the protective structure 4. The telescopic members 21 can be electric push rods, telescopic rods, hydraulic cylinders and other telescopic devices, so that the distance between the two second uprights 22 is adjustable, thus making the device suitable for building edges of different length ranges.
[0049] In this embodiment, as Figures 7-8As shown, a second fixing plate 222 is provided on one side of the inner wall opposite to the second mounting groove 221. Both second fixing plates 222 are parallel to the inner wall of the second mounting groove 221. Both second fixing plates 222 are rectangular and adapted to the second mounting groove 221. Both sides of the second upright 22 are provided with a second threaded rod 223 perpendicular to the side wall of the second upright 22. The second threaded rod 223 passes through the side wall of the second upright 22 and abuts against the side wall of the second fixing plate 222. The second threaded rod 223 is located at the center of the side wall of the second upright 22 in the vertical direction, and one end of the second threaded rod 223 abuts against the center of the second fixing plate 222. Thus, the second threaded rod 223 can be rotated to push the second fixing plate 222 against the outer wall of the protective structure 4 such as the steel pipe installed in the second mounting groove 221, thereby fixing the protective structure 4 such as the steel pipe.
[0050] In this embodiment, as Figures 7-9 As shown, two second limiting rods 224 are provided on both sides of the second upright 22. The two second limiting rods 224 on the same side are positioned opposite each other at the upper and lower ends of the second threaded rod 223. The axial direction of the second limiting rods 224 is consistent with the axial direction of the second threaded rod 223. One end of each of the two second limiting rods 224 passes through the side wall of the second upright 22 and is fixedly connected to the side wall of the second fixing plate 222, thereby stabilizing the position and displacement direction of the second fixing plate 222.
[0051] Among them, since the protective structure 4 mainly uses materials that are readily available on the construction site, such as steel pipes, the cost of this device is low and it is easy to transport.
[0052] The second fixing plate 222 is provided so that the second mounting groove 221 can be used to install and fix protective structures 4 such as steel pipes and square timber of different sizes.
[0053] In this embodiment, as Figures 7-8 As shown, rubber pads 7 are provided on the opposite sides of the two second fixing plates 222, so that protective structures 4 with small size differences can be installed in the second mounting groove 221 at the same time.
[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
