[0023] For ease of understanding, the edge opening protection device provided by the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings of the specification.

[0024] The utility model provides a protective device for edge openings, such as Figure 1-Figure 3 As shown, it comprises: a plurality of horizontally arranged handrails 1, each handrail 1 comprises a steel pipe 11 and two bases 12 respectively used for fixing the ends of the steel pipe 11;

[0025] The base 12 includes: a steel plate 121, and a C-shaped steel 127 connected to the steel plate 121; the steel plate 121 is fixed to the walls on both sides of the adjacent opening by expansion bolts, and the two ends of the steel pipe 11 are respectively placed in the C-shaped steel 127 and fixed to form a whole by bolts and nuts.

[0026] Compared with the prior art, the edge opening protection device described in the embodiment of the utility model has the following advantages:

[0027] In the edge opening protection device provided by the embodiment of the utility model, since each railing 1 includes a steel pipe 11 and two bases 12 respectively used to fix the ends of the steel pipe 11; and the base 12 includes: a steel plate 121, and a C-shaped steel 127 connected to the steel plate 121; the steel plate 121 is fixed to the walls on both sides of the edge opening by expansion bolts, and the two ends of the steel pipe 11 are respectively placed in the C-shaped steel 127, and fixed to form a whole by bolts and nuts; therefore, when the later construction is carried out, such as wall laying, door frame installation and other processes, it is only necessary to remove the bolts and nuts in one of the bases, and then rotate through the bolts of the other base, and only the bolts and screws need to be restored after the construction is completed. From this analysis, it can be seen that the edge opening protection device provided by the embodiment of the utility model can be used for multiple times after one investment, and the cost is effectively reduced; by using this protection device, in the later construction processes such as wall laying, plastering, etc., it is necessary to temporarily remove the protective railing, and it is not necessary to remove the protection, and it can be restored after the construction is completed, which is very simple and can be used continuously.

[0028] It should be noted that, in the edge opening protection device provided by the embodiment of the utility model, the C-shaped steel 127 is the core of the entire device. First, it is connected to the steel plate 121 of the base 12, and then connected to the steel pipe 11. That is, the C-shaped steel 127 plays both a fixing role and a bearing role in the middle, and the steel pipe 11 can be opened or closed by axial rotation (specifically, the steel pipe 11 can be rotated by screws and then fixed to another base 12).

[0029] Among them, Figure 1-Figure 3 As shown, the above-mentioned steel plate 121 can have a plurality of square holes 122 distributed in a matrix, and the square holes 122 can be used to penetrate the expansion screws 124 and cooperate with the expansion screw caps 123 to fix the steel plate 121 to the wall, so that the steel plate 121 can ensure that the base 12 is fixed to the walls on both sides of the adjacent opening through the expansion bolts.

[0030] Specifically, Figure 1-Figure 3 As shown, bolt holes 129 can be respectively provided at both ends of the steel pipe 11, and fastening bolt holes 128 can be correspondingly provided at the upper and lower parts of the C-shaped steel 127, and the fastening bolt holes 128 are adapted to the bolt holes 129; thus, the bolts 126 can be fastened and fixed by the nuts 125 after passing through the fastening bolt holes 128 and the bolt holes 129, thereby fixing the steel pipe 11 and the C-shaped steel 127 (i.e., the base 12) to form a whole.

[0031] Furthermore, if Figure 1-Figure 3 As shown, the C-shaped steel 127 and the steel plate 121 can be fixedly connected by welding (ie, forming a weld 13 ) to form an integral structure.

[0032] Among them, Figure 1-Figure 3 As shown, the C-shaped steel 127 can be processed into a C-shaped structure by a steel plate piece, and the width of the steel plate piece is larger than the diameter of the steel pipe 11, so that it is convenient to fix the steel pipe 11 through the C-shaped steel 127.

[0033] Specifically, Figure 1-Figure 3 As shown, the steel plate 121 may preferably have four square holes 122 distributed in a matrix, and the four square holes 122 may be evenly distributed around the steel plate 121, thereby facilitating the fixing effect of the base 12 and the wall.

[0034] Furthermore, if Figure 1-Figure 3 As shown, the steel plate 121 may be in a square structure, so as to facilitate the processing and assembly of the base 12 .

[0035] Furthermore, if Figure 1-Figure 3As shown, the distance from the end of the steel pipe 11 to the bottom relative to the center point of the C-shaped steel 127 can be 2 / 3, so as to facilitate the assembly of the steel pipe 11.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
