w beam guardrail metal crash barrier manufacturer introduce

w beam guardrail metal crash barrier manufacturer are specialized in providing guardrails, w beam guardrail metal crash barrier manufacturer are widely distributed in China.

Talking about Installation Requirements of Anti-collision Barrier.Because the section size of anti-collision barrier is basically large and small, the formwork must be pressed by embedded reinforcement bar to prevent the formwork from floating when pouring concrete.

w beam guardrail metal crash barrier manufacturer is easy to accumulate air bubbles on the side of the guardrail when pouring concrete. When pouring concrete, two layers of air bubbles should be poured at the corner, so that the air bubbles of the lower concrete can be dispersed as early as possible. In the process of concrete vibration, the slant of formwork is knocked artificially to minimize the phenomenon of more bubbles on the slant of concrete.

Bridges on horizontal curves should carefully check the position of guardrails and the relative relationship with beams and slabs so as to prevent the embedding of steel bars in w beam guardrail metal crash barrier manufacturer.

w beam guardrail metal crash barrier manufacturer the position and angle of the true seam should be accurate, and the die should be completely disconnected. After removing the moulds of the guardrail, the real joints should be cleaned up in time, and no hard objects such as concrete and stones should be left in the joints to prevent blind joints.

w beam guardrail metal crash barrier manufacturer class S guardrail belongs to the reinforced type, which is suitable for the use of roads with special danger on the roadside, and Class A is used for special highway.The approximate specifications of the price match are:

Guardrail: 4320*310*85*2.75/2.85/3.0Pillars: 114 * 4.5 * 1200 - 1800 (the height of the column depends on the installation terrain).Bracket: 70 * 300 * 4.5, or anti-blocking: 196 * 178 * 200 * 3

Guardrail end terminals

The bracket and the blocking block have the same function. They are directly connected to the plate and the column. They can be substituted for each other, but the cost of blocking prevention is higher.Column cap: 114 * 150 / 100 (114 suitable).Bolts are divided into connecting bolts and splicing bolts. M16*170, M16*42, M16*35
