[0040] Embodiment 1:

[0041] The protective fence protected by the utility model application includes a plurality of protective posts arranged evenly and linearly, and a plurality of transverse blocking members detachably connected to each protective post. The protective fence is arranged on a platform on top of a steel frame, and the steel frame platform is constructed by a plurality of evenly and parallel transverse steel bars and a plurality of evenly and parallel longitudinal steel bars, and the transverse steel bars are perpendicular to the longitudinal steel bars. In this embodiment, the protective fence is arranged parallel to the transverse steel bars and is arranged at the edge of the steel frame platform. The two sides of the protective fence are respectively a protective side close to the edge of the steel frame platform and a safety side away from the edge of the steel frame platform.

[0042] See also Figure 1 The protective column includes a base 1, a connection component and a support column 3. The transverse steel bar located at the setting position of the protective column is selected as the first steel bar, and the longitudinal steel bar located at the setting position of the protective column is selected as the second steel bar. The protective column is set at the intersection of the first steel bar and the second steel bar. The connection component fastens the base 1 with the first steel bar and the second steel bar, thereby achieving a temporary fixation effect. The support column 3 is detachably connected to the base 1 and remains in a vertical state under the support of the base 1.

[0043] See also Figure 1 , Figure 2 and Figure 3The base 1 includes a bottom plate 11 and a sleeve 12. The bottom plate 11 is constructed as a rectangular flat plate structure, which is horizontally supported above the first steel bar and the second steel bar. The size of the bottom plate 11 is matched with the spacing between adjacent transverse steel bars and adjacent longitudinal steel bars. In this embodiment, the center position of the bottom plate 11 corresponds to the intersection of the first steel bar and the second steel bar. At this time, the bottom plate 11 is supported by three transverse steel bars and three longitudinal steel bars at the same time, which improves the stability of the base 1. The bottom plate 11 is provided with two through holes 111, and the midpoint of the line connecting the two through holes 111 coincides with the center position of the bottom plate 11, and the direction of the line connecting the two through holes 111 has an angle with the first steel bar and the second steel bar. The sleeve 12 is arranged at the center position of the side of the bottom plate 11 away from the first steel bar, and is arranged perpendicular to the bottom plate 11, so that the two through holes 111 are distributed on both sides of the sleeve 12. The inner wall of the sleeve 12 is provided with a blocking portion 121, which includes two identical arc-shaped columnar structures. The blocking portion 121 of the sleeve 12 is formed at one end of the sleeve 12 away from the bottom plate 11, and its height is half the height of the sleeve 12. The two columnar structures are separated and evenly arranged from each other, so that two identical slots 122 are formed between the two columnar structures. The direction of the slots 122 is parallel to the longitudinal steel bars, and is used for connecting the support column 3.

[0044] The base 1 also includes two steel bar grooves 13 of the same structure, separated from each other and symmetrically arranged. The steel bar groove 13 is connected to the bottom plate 11 and is configured as a U-shaped structure. The steel bar groove 13 includes a connecting portion 131 and a parallel portion 131 connected to each other. The connection of the steel bar groove 13 is vertically arranged in a semicircular shape, parallel to the transverse steel bar and connected to the safety side of the base 1. The parallel portion 131 of the steel bar groove 13 is parallel to the base 1 and is arranged on the side of the transverse steel bar away from the base 1. The steel bar groove 13 has an opening facing the protective side of the protective fence, which is used to clamp the transverse steel bar, further reducing the risk of the protective column tilting toward the protective side of the protective fence. The width of the steel bar groove 13 is slightly smaller than the spacing between adjacent longitudinal steel bars, and the spacing between the two steel bar grooves 13 is slightly larger than the diameter of the longitudinal steel bar, so that the two steel bar grooves 13 are respectively located in the gap between the second steel bar and the longitudinal steel bars adjacent to both sides thereof. The length of the bottom surface of the steel bar groove 13 is adapted to the position of the through hole 111, so that the projection of the through hole 111 in the vertical direction is away from the bottom surface of the steel bar groove 13.

[0045] The connection assembly includes a U-shaped bolt 21 and two nuts 22. The U-shaped bolt 21 has two threaded ends 211, and the two threaded ends 211 are connected by an arc-shaped arc end 212 to form a nearly U-shaped structure. The two nuts 22, the two threaded ends 211 and the two through holes 111 of the base plate 11 cooperate with each other, so that the connection assembly is detachably connected to the base 1. Through the fastening connection between the U-shaped bolt 21 and the nut 22, the intersection of the first steel bar and the second steel bar is fastened and connected between the arc end 212 of the U-shaped bolt 21 and the base plate 11, thereby achieving temporary fixation of the base 1. In this embodiment, the two threaded ends 211 of the U-shaped bolt 21 are of different lengths, which facilitates the installation and fixation of the U-shaped bolt 21.

[0046] The support column 3 has a first end 31 and a second end 32 opposite to the first end 31. A clamping portion 33 that matches the blocking portion of the sleeve 12 is formed at the outer wall of the first end 31 of the support column 3. The outer wall diameter of the first end 31 of the support column 3 is the same as the inner wall diameter of the blocking portion of the sleeve 12. The clamping portion 33 of the support column 3 is configured to match the structure of the clamping groove 122 of the sleeve 12, and the height is the same as the blocking portion of the sleeve 12. After the clamping portion 33 of the support column 3 passes through the blocking portion of the sleeve 12 from the clamping groove 122 of the sleeve 12, it rotates in the horizontal direction, so that the clamping portion 33 of the support column 3 is clamped to the blocking portion of the sleeve 12, so as to realize the detachable connection between the first end 31 of the support column 3 and the sleeve 12. The second end 32 and the middle part of the support column 3 are provided with a lifting lug 34 for fixing a safety rope. The lifting lug 34 is configured in a U shape and both ends are connected to the support column 3, forming a vertically arranged annular structure. The direction of the lifting ear 34 is perpendicular to the clamping portion 33 . When the support column 3 is installed on the base 1 , the direction of the lifting ear 34 is parallel to the longitudinal reinforcement and is located on the protective side of the support column 3 . The two lifting ears 34 are located in the same vertical plane.

[0047] The support column 3 is also provided with a plurality of accommodating rings 35. In this embodiment, two accommodating rings 35 are provided, which are respectively located at the second end 32 of the support column 3 and the middle part of the support column 3, and the two accommodating rings 35 are located in the same vertical plane. The accommodating ring 35 is configured in a circular ring shape, parallel to the lifting ear 34, and is provided on the side opposite to the lifting ear 34. When the support column 3 is installed on the base 1, the accommodating ring 35 is located on the safe side of the support column 3. The height of the accommodating ring 35 is substantially the same as that of the lifting ear 34, which helps to balance the protective column.

[0048] See also Figure 4The transverse blocking member includes a plurality of blocking steel pipes 41 connected end to end and stoppers 42 arranged at both ends of the transverse blocking member. The outer wall diameter of the blocking steel pipe 41 is slightly smaller than the inner wall diameter of the accommodating ring 35, and passes through the inner wall of the accommodating ring 35. The blocking steel pipe 41 with a shorter length is easy to install, and the blocking steel pipe 41 is supported and limited in the accommodating ring 35. When the blocking steel pipe 41 is subjected to a force toward the protective side of the protective fence, the blocking steel pipe 41 contacts the support column 3, thereby improving safety. In this embodiment, the structures of the blocking steel pipes 41 are the same. One end of the blocking steel pipe 41 is configured as a cylindrical structure with threads formed on the outer wall, and the other end is configured as a circular cylindrical structure with threads formed on the inner wall. The threads at both ends cooperate with each other, so that the adjacent blocking steel pipes 41 are connected end to end. The stoppers 42 are all configured in a right angle shape, and the two ends are respectively configured in the same structure as the two ends of the blocking steel pipe 41, so that the two sets of protective fences can be connected at a right angle.

[0049] The beneficial effect of this embodiment is that it improves the convenience of installing and disassembling the protective fence, saving time and effort. After disassembly, the protective fence can be recycled and reused, and the structure of the steel frame platform does not change, saving costs and reducing damage to the structure of the steel frame platform. The overall structure is relatively strong, which helps to improve safety performance.

[0050] Embodiment 2:

[0051] The only difference between this embodiment and the first embodiment is that this embodiment includes two types of blocking steel pipes 41, both ends of one blocking steel pipe 41 are constructed as a cylindrical structure with threads formed on the outer wall, and both ends of the other blocking steel pipe 41 are constructed as a ring columnar structure with threads formed on the inner wall, and the two types of blocking steel pipes 41 are arranged at intervals and connected to each other.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
