Description
Technical field
The utility model relates to a kind of concrete hollow building roof building structure technology field, is specifically related to a kind of arc gypsum evacuated mould box structure, and it is to add the one-time formed light-weight building material of fortifying fibre by the gypsum powder body material to pour into.
Background technology
In field of civil engineering, steel concrete is low, sturdy and durable owing to cost, thereby is used in a large number.For floor system, normally form jointly by beam and plate.Depth of beam is more much bigger than thickness of slab, wants head beam at the bottom of the plate, and the building headroom is reduced.When post net span is big, for satisfying rigidity requirement, need to strengthen deck-molding, make the building headroom littler.For overcoming this defective and increasing superstructure rigidity, the close rib building roof system has appearred.Under identical span, close girt strip height is less, and good rigidity is stressed relatively good.But the defective of close rib building roof is that construction is complicated, because close girt strip spacing is less, the formwork more complicated is time-consumingly taken a lot of work and consumed template.For simplifying working procedure, special-purpose formwork such as polypropylene plastic forms frp mould appearred.This formwork is as construction formwork, and concrete will be removed after reaching early strength, and the formwork of scrapping can pollute environment.Use the still inconvenience popularization of special-purpose formwork for a large amount of medium and small engineerings.
In the last few years, packing material replaced formwork and the development and the utilization of the cast-in-situ hollow building roof that forms have had large development.Such as BDF thin wall cylinder core hollow building cover, WFB hollow-ribbed floor.They are that cylindrical duct or thin-wall box body are built in superstructure with concrete, form the superstructure deadweight and reduce, save concrete arch without beam.The utility model proposes a kind of hollow building cover that adopts novel packing material, promptly be filled in the hollow building cover with the arc plaster mould box, the diaphragm capsule build of design is reasonable, easy to use, and the construction period diaphragm capsule is as the template of concreting; Application phase diaphragm capsule is not removed, and is stressed jointly with concrete.Use the arc plaster mould box to be filled in the superstructure and compare and have the advantages that rigidity is big, shock resistance is strong, bearing capacity is high with conventional concrete floor system structure.Can save reinforcing bar, concrete consumption significantly.Reduce the building deadweight, reduce construction costs, have better economic.Because deck-molding is less, the building headroom is increased.The concrete floor system bottom of moulding, smooth in appearance is smooth, and the flooring partition wall is flexible arrangement arbitrarily.Because the existence of mould internal cavity, hollow rate is big, and structural weight per square meter is reduced, and superstructure sound insulation, heat-proof quality are good.Primary raw material ardealite, desulfurated plaster that diaphragm capsule is made are the discarded objects of phosphate fertilizer plant and steam power station.Reclaim refuse reclamation, walk recycling economy, the road of sustainable development meets the national industrial policies guiding.Simultaneously, gypsum is again desirable constructional materials, and it is low to have unit weight, and the initial setting time is short, the characteristics that shape easily
Summary of the invention
The purpose of this utility model is that a kind of processing and fabricating that provides is easy, stress good, sound insulation, insulation, fireproof performance are good, and dead load is little, and crack resistance is good, the arc gypsum evacuated mould box that tensile strength is high.
The technical scheme that the utility model technical solution problem is adopted is:
Arc gypsum evacuated mould box, include gypsic horizon (4) and cavity (5), it is that gypsic horizon (4) is positioned at external surface, arc gypsum cavity (5) is positioned at the inboard, ribs (6) is established in the cavity center, the diaphragm capsule facade is symmetrical combinatorial surface by vertical facade (11), and the bottom is by contacting stressed circular arc (8), circular arc (9) part formation with girt strip, and the bottom surface is smooth rectangle (10).
The cross section cavity is circular-arc or parabolic shape (7) in the above-mentioned arc gypsum evacuated mould box, its arcuation, and the ribs (6) that set up the center is cross.
Above-mentioned arc gypsum evacuated mould box, its planar dimension is from 500mm～2400mm.
The utility model compared with prior art; by above structure as can be known: the outer side elevation of plaster mold is combined by arc surface and vertical face, and the cross section is circular-arc or parabolic shape in the cavity, thereby is convenient to Mold Making in the process; prefabricated processing diaphragm capsule is convenient in demoulding, and is easy to accomplish scale production.In the handling process, can avoid the damage that causes by wedge angle; The cavity inboard is arcuation and arranges that the principle that can make full use of arching is born floor load.Construction period, the effect of arch makes the arc diaphragm capsule can better bear constructor's working load such as materials hauling, assembling reinforcement thereon, though diaphragm capsule is thin, can not damage.
