Description
Technical field
This technology relates to the core rod that Extruder for concrete core slab uses, and specifically, is the core rod extruding use in storehouse of Extruder for concrete core slab.
Background technology
In order to produce concrete core slab, generally use Extruder for concrete core slab.This Extruder for concrete core slab has one and extrudes storehouse, and core rod is arranged on to be extruded in storehouse.Concrete (material) is added the import of extruding storehouse, then material is promoted by push pedal, make material through core rod and the gap of extruding between the inwall of storehouse, again from extruding the outlet in storehouse out, when concrete leaves core rod, core rod place originally just defines concrete hollow part, has so just produced concrete core slab.Existing core rod, generally the periphery of its cross section remains unchanged, and causes that the concrete of concrete core slab hollow part periphery easily caves in, slump, causes the concrete core slab of preparation off quality.
Summary of the invention
The object of this technology is to provide a kind ofly can ensure that the hollow part periphery concrete of the concrete core slab prepared is intact, can not cave in, the core rod extruding use storehouse in of the Extruder for concrete core slab of slump.
This Extruder for concrete core slab extrude the core rod used in storehouse, core rod passes through, and reduces gradually after the periphery of its cross section increases gradually again.
The beneficial effect of this technology: due to the periphery of core rod cross section increase gradually after reduce gradually again; That is, core rod outer surface and the gap of extruding between the inwall of storehouse first reduce to increase gradually more gradually.We are core rod outer surface and extrude the region that gap between the inwall of storehouse first reduces gradually and be referred to as compressional zone, and core rod outer surface and the region increased gradually after extruding between the inwall of storehouse gap are referred to as to loosen district.When concrete passes through from core rod outer surface and the gap of extruding between the inwall of storehouse, first from compressional zone by time increased by compacted, density, and then through loosening district, volume of concrete after compression increases, unclamps (its internal stress may be made to be discharged), when such concrete leaves core rod, core rod place originally just defines concrete hollow part, and the concrete of hollow part periphery can not cave in, slump.If core rod outer surface and the gap of extruding between the inwall of storehouse remain unchanged or remain unchanged after first reducing gradually again, concrete is compressed rear one and is kept this state, when leaving core rod Deng concrete, perhaps due to the releasable more greatly and not reason of concrete internal stress, the concrete of hollow part periphery also can cave in, slump, and product quality is defective.
Above-mentioned core rod, core rod passes through, and remains unchanged again, and then reduce gradually after the periphery of its cross section increases gradually.Core rod passes through, and remains unchanged again, and then reduce gradually after the periphery of its cross section increases gradually.We are core rod outer surface and extrude the region that the gap between the inwall of storehouse remains unchanged and be referred to as pressurize district, when concrete passes through from core rod outer surface and the gap of extruding between the inwall of storehouse, first from compressional zone by time increased by compacted, density, keep volume, density constant again through pressurize district, and then through loosening district, volume of concrete after compression increases, unclamps (its internal stress may be made to be discharged), like this, the change of concrete internal stress is more mild, prevent hollow part periphery further concretely to cave in, slump.
Above-mentioned core rod, described core rod has multiple, and each mold insert structure is identical; Each core rod maximum cross section area sum is x, each core rod one end cross-sectional area sum is y, each core rod other end cross-sectional area sum is z, extrude storehouse cross-sectional area w, 3.5 (w-x) >=w-y >=2.5 (w-x), w-x> w-z>w-y.Like this, further ensure concrete compression ratio (about 2.5 to 3.5 times), meanwhile, also ensure that the concrete of hollow part periphery can not cave in, come off, improve the quality of cored slab.
Above-mentioned core rod, each core rod is distributed on same horizontal plane, and the distance between adjacent two core rods is equal.Like this, the cored slab with multiple hollow part (identical with core rod quantity) be positioned in same level can be produced.The core rod one end cross section be connected with knife rest bar is hexagon, and other end cross section is the quadrangle of band fillet.Like this, on the concrete core slab produced, namely hollow part is the quadrangle of multiple band fillet be positioned in same level, and this cored slab can carry larger power.
Above-mentioned core rod, each core rod is distributed at least two horizontal planes, and the distance between adjacent two core rods of a horizontal plane is equal, and the core rod being positioned at different level staggers setting up and down.Like this, the cored slab with multiple hollow part (identical with core rod quantity) be positioned on different level can be produced.Core rod is distributed on three horizontal planes, and the core rod other end is hexagon.Like this, on the concrete core slab produced, namely hollow part is multiple hexagons be positioned on three horizontal planes, and this cored slab can carry larger power, and the concrete of hollow part periphery caves in, the possibility that comes off is less.
