Description
(1) technical field
The utility model relates to the packing material in a kind of reinforced concrete hollow floor structure, and the gas cell of especially a kind of landfill in concrete belongs to buildings in general structure field.
(2) background technology
At building field, along with the large-span concrete structure is increasing, increasing floor adopts the hollow building cover structure technology.Sometimes in order to reduce dead load or to strengthen concrete insulation, heat insulation, sound insulation, damping effect, need place some lightweight fillers in the concrete the inside.Come the instead of part concrete can not influence the stress performance of structure substantially with lightweight filler, but the deadweight that can alleviate structure greatly.
From the construction angle, construction most convenient when the cross sectional shape of packing material is circle or polygon, concrete is built closely knit easily.In " concrete thin-wall cylindrical shell member " (ZL98231113.3) " fibre reinforced hollow thin-wall tube for filling in bar reinforced concrete and manufacture method thereof " (ZL99115649.8) and in " having the light porous material obturator that multiple cross sectional shape is used for concrete " (ZL02293406.5) etc. early stage correlation technique, packing material cross sectional shape circular or near circular.But this cross sectional shape hollow building cover is that hollow rate is less, and is economical relatively poor.
From mechanics principle, the desirable cross sectional shape of packing material is a rectangle, the hollow rate maximum that can make superstructure of this shape, and structure is the lightest.But the greatest drawback of this cross sectional shape packing material is: can't guarantee that the concreting below the packing material is closely knit.Therefore, Mr. Wang Benmiao has invented " thin wall box in-situ poured concrete hollow slab thin-wall box body " (ZL02282207.0), this thin-wall box body is a tabular, seal with top, bottom panel by perisporium, at the casing axis of centres to hollow section is set, connect box top, bottom panel, the centre bore of hollow section runs through top, bottom panel, and concrete can be closely knit with the concreting below the casing by hollow section.But the casing central hollow tube is provided with, and it is stressed to make concrete in the hollow section not participate in any structure, just increases the deadweight of superstructure.Afterwards, I have invented " a kind of lightweight foam material filling member with the hard enhancement Layer " (ZL200420077923.9), the upper and lower surface configuration of packing material is broken line or camber line, though it is smaller that the hollow rate of superstructure is compared with the square-section, can guarantee concrete construction quality well.Mr. Wang Benmiao had applied for two appearance designs afterwards again, be respectively " casing (fillet) " (ZL200530117113.1) and " casing (right angle) " (ZL200530117112.7), in above-mentioned appearance design, the upper and lower surface design of casing is become cambered surface, but this shape is suitable for GRC class material.
On hollow building cover packing material material, several big classes such as metal material, high-strength cement goods (GRC), rubber or plastic products are roughly arranged, pluses and minuses are respectively arranged during use.The metal bellows cost is higher, and foot-operated the rubbing in when construction cause bellows seaming cracking easily, and electricity, gas welding carry out operation and may burn hole if be close to bellows simultaneously.The hollow section deadweight of being made by fragile material (high-strength cement etc.) is bigger, and water absorption rate is higher, and is cracked easily when withstanding shocks load and stacking weight.Rubber or plastic thin-wall tube need to strengthen wall thickness and cause cost higher if will keep certain intensity.Therefore developing the air filling type packing material also has a good application prospect.
At present the technology that adopts the inflation mode to form packing material has: " shaped form combination inflation internal mold " (ZL87205722), be characterized in easily to curve the single flexible pipe inflation and the combination of various curves, form the combination inflating die of different cross section contour shape by the plastic pipe of varying number flexible pipe and different-diameter respectively; Or utilize thin metal sheet to make the core skeleton of various curves, on every side with the combination inflating die of soft gas tube parcel with formation different cross section shape.My relatives once invented " a kind of inflation light-wall pipe that plays filling effect that is used for concrete " (ZL02293407.3), and this inflation light-wall pipe is made up of light-wall pipe, end plug, fluid sealant, barrier coating, air-filled pore and compressed air.The technology that Mr.'s Qiu Zeyou patented technology " a kind of inflation mould component for concrete filling " (ZL200710200791.2) is disclosed is two-layer covering clamping wrapping frame, two-layer covering forms the capsule of sealing, covering is provided with charging connector, forms each surface of obturator." a kind of inflating mould for concrete filling " be disclosed inflating mould (ZL200710200852.5), comprise soft mode wall, inflation plug-in unit, the sealing of soft mode wall constitutes loose tool, and the inflation plug-in unit is for extracting the charging connector that plug-in unit can seal voluntarily out, and the soft mode wall is provided with charging connector." a kind of inflating mould for concrete filling " (ZL200710200795.0) then discloses a kind of charging component is basin-shaped component, forms tub wall by gas cell, and the inwall of charging component is or/and outer wall is provided with skeleton or drawstring or stay cord.More than three kinds of technology are each faces that constitute obturator by independent two-layer covering inflation back, for a hexahedron, the covering of 12 faces, relatively waste material.In 200710200795.0, by being provided with skeleton or drawstring or stay cord, only be that each face with obturator links together, do not go to control the shape of the single external surface of obturator by drawstring or stay cord.
In above-mentioned numerous technology, different shortcomings is arranged respectively, in this case, it is reasonable to develop a kind of cross sectional shape, easy to makely can be used for the air filling type product that concrete is filled, and has become urgent problem in the current hollow building cover.
(3) summary of the invention
In the prior art, have that the hollow building cover hollow rate is low, structure stress is unreasonable, the packing material cost is higher or problem such as inconvenience is installed, the purpose of this utility model is to provide the gas cell of a kind of landfill in concrete, this gas cell cross sectional shape is relatively more perfect, under the prerequisite that guarantees structure stress, can improve the hollow rate of superstructure as much as possible, can guarantee concrete pouring quality again, this production, transportation and installation simultaneously is all very convenient, and the anti shock and vibration performance is good.
