Pier head reinforced ultra-high performance concrete cover plate and production method thereof
The invention discloses a pier head reinforced ultra-high performance concrete cover plate. The pier head reinforced ultra-high performance concrete cover plate comprises an ultra-high performance concrete layer, wherein a steel bar framework parallel to the lower end surface of a cover plate body is arranged at the position, which is far away from the lower end surface and four sides of the cover plate body by a distance of 10-20mm, in the ultra-high performance concrete layer; the steel bar framework comprises longitudinally arranged stress bars and horizontally arranged distribution bars; pier heads are arranged at two ends of each stress bar; the outer diameter of the pier heads is 1.3-2.0 times to the diameter of the stress bars. The invention also discloses a production method of the pier head reinforced ultra-high performance concrete cover plate. The pier head reinforced ultra-high performance concrete cover plate can be used for improving the sliding resistance between the steel bars and ultra-high performance concrete in the cover plate, delaying the occurrence of cracks of the cover plate, improving the crack load of the cover plate and improving the durability of cover plate products, and has a very good economic benefit.
