Specifications and installation standards of 4.5-meter high anti-climbing metal partition walls for prisons​, access doors and access doors

1. 4.5 meters high anti-climbing metal isolation mesh wall

 

1. 4.5m high anti-climbing metal fence
Main technical specifications of anti-climbing metal isolation net
(1) The total height of the metal isolation net is 4500mm, the height of the mesh is 4000mm, and the distance between the center of the column is 2500mm.
(2) The column material is Q235B cold-formed steel, the column specification: 60*60*3mm, the column flange chassis 120*120*10mm and the embedded steel plate are welded and fixed.
(3) The connecting side ear pieces of the mesh and the column are 40*40*4mm.
(4) A metal cap is installed on the top of the Y-pillar support.
(5) The frame material is Q235B cold-formed square steel, the mesh frame is 40*20*2.0mm, and the mesh hole is 100*150mm diamond-shaped hole. The mesh wire and the frame are welded, and the welding quality meets the requirements of the CO2 shielded welding welding procedure specification.
(6) The height of the mesh frame from the ground is not more than 100mm;
(7) Surface treatment: The raw material mesh and column are treated with plastic spraying, and the surface has no bad phenomena such as pinholes, cracks, plastic leakage, and plastic liquid flowing.

(8) Surface treatment of the screen frame: dark green plastic spray (the same color as the original installation, the thickness of the plastic layer is ≥ 150um);

2. Stainless steel 304 accordion-shaped knife barbed wire: technical specifications barbed wire length 22mm±1mm, width 15mm±1mm, plate thickness 0.5mm±0.05mm, inner wire diameter 2.5mm±0.1mm, knife spacing 36mm±1mm; technical requirements: 10 single circles per meter, the diameter of the barbed circle is 500mm, and both inside and outside are made of SUS304 stainless steel + secondary coating to repair scratches (double-layer anti-corrosion). It is fixed with 4 stainless steel wires with a diameter of 2.5mm. The wire drawing and stabbing are tied with stainless steel wires with a diameter of 1mm or special clips. The material is SUS304;
3. The metal isolation mesh should be treated with double anti-corrosion treatment of “hot-dip galvanizing + surface dark green spraying”, and the designed anti-corrosion period is not less than 10 years.

4. Installation basis and installation part
(1) Basic part (may be determined according to the actual environment of the site)
A. The size of the foundation pit: 400mmX400mm*500mm, the embedded plate is 150*150*10mm, 4 Ø12 steel bars are reinforced and embedded, and the steel plate and the column are fully welded. The excavation depth is 500mm (if the soil is backfilled, the foundation depth needs to be below the backfill);
B. Pre-embedded is adopted, and the bottom of the column needs to be lengthened by 500mm;
C. The bottom of the foundation pit is compacted, and the formwork is poured with C25 concrete.
(2) Installation part
A. The mesh must be connected to the Y-shaped column with anti-disassembly bolts to form a solid anti-climbing steel mesh wall.
B. Stainless steel 304 accordion-shaped barbed wire mesh is straightened and evenly arranged not less than 7 circles/meter.
C. All connections must be tight and not loose.
