While some guard rails adjacent the edge opening are also disclosed in the prior art, further optimization of the existing rail construction is needed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is overcome prior art not enough, provide a building site with facing limit entrance to a cave protector, it has higher efficiency of setting up efficiency, demolising temporarily and recovering, and installation, dismantlement, the interim all simple easy operation of relieving, the aesthetic property is stronger.
In order to solve the technical problem, the utility model provides a technical scheme does: a protection device for a side opening for a building site comprises a plurality of railings which are arranged in parallel, wherein each railing comprises a steel pipe and two bases which are used for fixing the end parts of the steel pipe respectively; the base is fixed on the wall on the two sides of the edge opening through expansion bolts.
As a further improvement of the above technical solution: the steel sheet groove is of a transverse trapezoidal structure with an opening at the bottom formed by bending a steel sheet twice, and the width of the steel sheet is larger than the diameter of the steel pipe.
Furthermore, the number of the threaded holes on each base is three or four, and the threaded holes are evenly distributed in different directions of the base.
Furthermore, the base is of a square structure or a circular structure, and the side length or the diameter of the base is 80-150 mm.
Further, the fastening bolt is provided on an upper side or a lower side of the steel sheet groove.
Further, the height of the fastening bolt relative to the base surface is not less than the diameter of the 1/2 steel pipe.
Further, the steel sheet groove and the base are of an integrated structure, or the steel sheet groove and the base are fixedly connected in a welding connection mode.
Further, the distance between two adjacent railings is not more than 0.4m, and the distance between the railing of the lowermost layer and the bottom edge of the edge opening is not more than 0.4 m.
Compared with the prior art, the utility model has the advantages of:
when the utility model is used, firstly, holes are drilled on two sides of the near-edge opening, the base is fixed by expansion bolts, then the steel pipe is placed in the steel pipe groove on the base, the steel pipe is fixed by twisting the fastening bolts, when the steel pipe is temporarily removed, the steel pipe can be removed by twisting the fastening bolts, the protection is removed, and the steel pipe is installed when the steel pipe is recovered; demolish the later stage, demolish the steel pipe earlier, demolish the base afterwards, collect regularly, use repeatedly, have higher efficiency of setting up, demolish temporarily and the efficiency that resumes, installation, dismantlement, interim removal all simple easy operation, the aesthetic property is stronger, safety ring protects.
