Abstract
The invention discloses a steel-shelled reinforced concrete structural member. The structural member is a structure provided with at least two corresponding junction surfaces, wherein the structure is a hollow shell composed of a plurality of surface plates and curved plates, the hollow shell is formed by welding plates made of low-carbon steel and medium-carbon steel or casting cast steel, nodular cast iron and gray cast iron, and the thickness of each steel plate or the wall thickness of the casting is about 5-100mm; concrete and reinforced concrete are poured into the hollow shell; the hollow shell comprises side plates and connecting cover plates; at least one connecting cover plate is equipped with a pouring opening and a filling cover plate for sealing the pouring opening, and the connecting cover plates can be opened; and transverse thorn-shaped reinforcing bars are welded or cast on the inner surface of the hollow shell. The structure meets the requirements for mechanical manufacturing strength, reduces the transportation weight, lowers the transportation cost, shortens the machining, manufacturing and assembling period, and greatly lowers the comprehensive cost.
Description
Technical field
The present invention relates to a kind of structural member of the prestressed combined structure for weight equipment manufacture, especially a kind of prestressing force steel-shelled reinforced concrete structural member for hydraulic press.
Background technology
Heavy combining structure is adopt multiple structural member to form an overall structure through bolt or steel wire winding pretension.Because the structural member yardstick of combining structure is little, lighter in weight, manufacture difficulty are less, be convenient to transport and with low cost, adopted widely, the frame, the operating pressure that reach tens thousand of tons as carrying reach the high-pressure bottle, working cylinder, heavy dies etc. of 40-90MPa.Traditional reinforced concrete structure vibrates pouring, solidification forming in a template, because the die cavity precision be made up of template is low, and exists and solidifies-knockout course, cause drip molding precision not reach the required precision of mechanized equipment to component; On the other hand, mechanical weight equipment is collided unavoidably, and exposed concrete surface is also inappropriate, and thus traditional reinforced concrete structure cannot be used as the structural member of heavy combining structure.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of steel-shelled reinforced concrete structural member, steel concrete be not shaped in the template be disassembled, but be shaped in box hat, comprise High Temperature Curing and be shaped from shape pouring, once be shaped, steel concrete is no longer separated with box hat.Due to the existence of box hat, the accuracy of manufacture of pre-box hat reinforced concrete composite structure part can be made to reach the precision level of the combined structural members such as steel, cast iron casting, weldering and casting-weldering completely, meet the requirement of strength of machine-building, and hauled weight alleviates, reduce cost of transportation, in the cycle shorten processing, manufacturing and assemble, decline to a great extent integrated cost.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A kind of steel-shelled reinforced concrete structural member, described structural member is the structure at least with two corresponding joint faces, and described structure is the hollow housing of some planes and curved slab composition.
As a further improvement on the present invention, described hollow housing is to be welded by the sheet material of mild steel, medium carbon steel or cast steel, magnesium iron, grey iron casting form, and the wall thickness of steel plate thickness or foundry goods is about 5 ~ 100mm.
As a further improvement on the present invention, placing of concrete in described hollow housing.
As a further improvement on the present invention, steel concrete is watered in described hollow housing.
As a further improvement on the present invention, described hollow housing by side plate be connected cover plate and form, described at least one connection cover plate is provided with pouring mouth, be convenient to supplement placing of concrete in structure, supplement placing of concrete, and be provided with the filling cover plate can closing pouring mouth thereon, close pouring mouth with this.
As a further improvement on the present invention, described connection cover plate can be opened, so that a large amount of placing of concrete, then closes.
As a further improvement on the present invention, the concrete in described hollow housing can carry out centrifugal pouring, and High Temperature Curing and obtaining.
As a further improvement on the present invention, the inner surface of described hollow housing welds or is cast with laterally thorn shape rib, and laterally thorn shape rib plays the effect of the adhesion of increase box hat and steel concrete.
As a further improvement on the present invention, described hollow housing welds or has been cast with and reuses suspension ring, described suspension ring position is higher than the center of gravity of hollow housing, and during to ensure to lift by crane, structure can not turn over by Pour.
As a further improvement on the present invention, have at least one to connect cover plate not weld with side plate, and its face profile size matches with the overall size of the inner chamber of housing, described cooperation is loose fit, to ensure that prefastening load acts on steel concrete completely, instead of on box hat.
The invention has the beneficial effects as follows: the steel-shelled reinforced concrete structural member that the present invention proposes can give full play to the advantage of the high compressive strength of steel concrete, and its cost counts the structural member of the combining structure that the metal material such as cast steel, gray iron and the magnesium iron picking up ton are made far below certainly weighing.Be wound around in combining structure at various compressor wire, structural member mainly bears compressive load, and tensile stress can be controlled in lower scope, this is the main cause that box hat reinforced concrete structure can be adopted to do structural member, the steel concrete of carrying is creatively placed in by welding (, steel plate weld) and casts among box hat that (hollow casting) manufacture by the present invention, the various sizes such as the profile of box hat and the machined requirement reaching machine-building specification of form accuracy; Also be the protection to the steel concrete in it simultaneously.The box hat Plate Welding of 5 ~ 100mm forms, after machined raising appearance and size precision, then can in specialized factory centrifugally cast concrete carry out High Temperature Curing, the value of compressive stress improving steel-shelled concrete label with this and bear.Also accurately can process further the relative dimensions of box hat after pouring maintenance and be convenient to assembling and pretension winding.In general need join suitable reinforcing bar to heavy and medium texture part, and to small-scale structure part, then can be unworthy of reinforcing bar.Box hat internal chamber wall welds some thorn shape ribs, box hat and concrete strong bonded can be increased.The design of box hat should ensure that compressive load that pretension construction formed is born primarily of the concrete kernel of steel concrete, i.e. steel-shelled reinforced concrete structural member, and should not born by box hat.Steel-shelled reinforced concrete structural member is transported to heavy type structure erecting bed respectively, through assembling assembly, becomes as a whole combination heavy type structure by bolt or steel wire winding pretension.The manufacturing cost of box hat reinforced concrete composite structure part is far below the structural member of iron, steel, and hauled weight alleviates, and reduces cost of transportation, shortens processing, manufactures and cycle of assembling.
