Description
Technical field
Present technique relates to the core rod that uses on the concrete core slab extruder, specifically, is the core rod that uses in the storehouse of extruding of concrete core slab extruder.
Background technology
In order to produce concrete core slab, generally use the concrete core slab extruder.This concrete core slab extruder has one and extrudes the storehouse, and core rod is arranged on to be extruded in the storehouse.Concrete (material) is added the import of extruding the storehouse, then promote material by push pedal, make material through core rod and extrude gap between the inwall of storehouse, again from the outlet of extruding the storehouse out, when concrete leaves core rod, core rod place has originally just formed concrete hollow part, has so just produced concrete core slab.Existing core rod, generally the periphery of its cross section remains unchanged, and causes the concrete of concrete core slab hollow part periphery easily to cave in, slump, causes the concrete core slab of preparation off quality.
Summary of the invention
The purpose of present technique be to provide a kind of hollow part periphery concrete that can guarantee the concrete core slab for preparing intact, can not cave in, the core rod of extruding the use storehouse in of the concrete core slab extruder of slump.
The core rod of extruding use in the storehouse of this concrete core slab extruder, core rod passes through, and the periphery of its cross section reduces after increasing gradually more gradually.
The beneficial effect of present technique: reduce gradually again after increasing gradually due to the periphery of core rod cross section; That is to say, core rod outer surface and the gap of extruding between the inwall of storehouse first reduce to increase gradually more gradually.We are the core rod outer surface and extrude the zone that the gap between the inwall of storehouse first reduces gradually and be referred to as the compressional zone, behind core rod outer surface and the gap of extruding between the inwall of storehouse gradually the zone of increase be referred to as to loosen the district.Concrete is from the core rod outer surface and extrude gap between the inwall of storehouse when passing through, compressed compacting when first passing through from the compressional zone, density increase, and then through loosening the district, volume of concrete after compression increases, unclamps (may make its internal stress be discharged), when concrete leaves core rod like this, core rod place has originally just formed concrete hollow part, and the concrete of hollow part periphery can not cave in, slump.If the core rod outer surface and extrude that gap between the inwall of storehouse remains unchanged or first reduce gradually after remain unchanged again, this state of the compressed rear a kind of maintenance of concrete, when leaving core rod Deng concrete, the reason that perhaps can not discharge because the concrete internal stress is large, the concrete of hollow part periphery also can cave in, slump, and product quality is defective.
