The first point, the technical requirements of the fence material
1 handrails should adopt the diameter 32mm (2.5mm thickness) of the steel column should adopt the diameter 32mm (thickness 2.5mm) steel tube, column clearance should be 1000mm.
2 by 150 x 3 manufacturing flat baffle. If the platform is provided with other structures that meet the requirements of the baffle and strength, allow for no other baffle.
3 all the components of the railing with a performance of not less than A - F Q235 steel manufacturing.
4 by 30 * 4 steel bar. The spacing of the bar and the upper and lower members shall not be greater than 380mm.
5 the structure of the rail should be welded, welding requirements should be in accordance with the technical requirements of GBJ 205, should be full of welding, welding firm, after welding should be the reliability of the experiment. When the welding is inconvenient, but also can be bolted connection, but must ensure that the structural strength of the provisions of the fifth chapter.
The 6 rail surface must be carefully and rust, anticorrosion coating.
7 rail should be around the connection or the end must be set up or connected to the building, and no one side of the fence.
8 all structural surfaces shall be smooth and without burr, and shall not be crooked, twisted, deformed and other defects after installation.
9 outdoor railing, the gap between the platform and the platform is 10 ~ 20mm, indoor without gap.
Second points, fence color: yellow.
Third, according to the regional or equipment to set the appropriate specifications for the safety of the fence.
Fourth points, fence height: when the platform, the channel and the working site is less than 2m, the height of the protective railing should not be less than 900 mm. In the distance from the base height is greater than or equal to 2M and less than 20m of the platform, channel and operating sites should not be less than 1050mm. In the distance from the base height is not less than 20m of the platform, channel and operating sites should not be less than the height of the protective railing 1200mm. Stationary industrial protective railings; protective equipment (see photo) for the installation of fixed installations along platforms, channels and workplaces. Vertical member of a railing. A protective member fixed to the upper end of the upright post. Bar: the connecting rod is fixed to the middle of the column. Shield plate fixed to the lower part of the upright post.
Fifth point, the strength of the requirements of the design of the rail, must ensure that the arm can withstand the horizontal direction of the vertical load is not less than 500N/m.
